Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The embodiment of the disclosure provides an adapter, as shown in fig. 1 and fig. 2, the adapter includes a socket body 1 and a power-taking body 2, and the socket body 1 is fixedly connected with the power-taking body 2. The socket body 1 includes a socket housing 11 and a socket assembly 12, the socket assembly 12 being located inside the socket housing 11. The power take-off body 2 includes a power take-off housing 21, a contact assembly 22, and a driving member 23. The contact assembly 22 is electrically connected to the socket assembly 12, one surface of the contact assembly 22 has a contact 220, and a portion of the sidewall of the power-taking housing 21 corresponding to the contact 220 has an opening 210. The driving member 23 is movably connected to the power-taking housing 21, and the driving member 23 is configured to control the contact 220 to extend out of or retract into the power-taking housing 21 through the opening 210.

Wherein the socket body 1 is used for butting a plug. The socket body 1 includes a socket housing 11 and a plug bush assembly 12, and a portion of the socket housing 11 corresponding to the plug bush assembly 12 has a plug hole into which a plug is inserted. In addition, the socket body 1 may further include a protective door assembly located inside the socket housing 11 and blocking the insertion holes.

The electricity taking body 2 is used for extending into the track to take electricity. The power taking body 2 is fixedly connected with the socket body 1, in some examples, as shown in fig. 1, the power taking body 2 is fixedly connected with one side of the socket body 1, which faces away from the jack, and a gap for accommodating a side wall of the track is formed between the power taking body 2 and the socket body 1. In other examples, the power extractor 2 may be fixedly connected to a sidewall of the socket body 1, the sidewall being perpendicular to a wall of the socket. The electricity collector 2 may also be called an insertion sheet, a hanging sheet, or the like.

The contact assembly 22 has contacts 220, the contacts 220 for contacting conductive strips in the track to draw electricity from the track. The contact piece assembly 22 may include two contact pieces 221 (L-pole contact piece and N-pole contact piece), or may include three contact pieces 221 (L-pole contact piece, N-pole contact piece, and E-pole contact piece). One face of each contact pad 221 may have one contact 220. In some examples, as shown in fig. 1, the plurality of contacts 220 differ in height along the insertion direction of the power take-off 2. Of course, the heights of the plurality of contacts 220 may be the same, which is not limited by the embodiment of the disclosure.

The driving member 23 is used for controlling the contact 220 to extend out of or retract into the electricity-taking housing 21 through the opening 210, and the implementation manner of the driving member 23 may be various, which is not limited in the embodiment of the disclosure.

According to the technical scheme shown in the embodiment of the disclosure, when the adapter is in the power taking state, the driving part 23 controls the contact 220 to extend out of the power taking shell 21 so as to be in contact with the conducting strip in the track. When the adapter is in a power-off state, such as being pulled out of the track, the driving member 23 can control the contact 220 to retract into the power taking housing 21, so as to reduce the possibility that the contact 220 is abraded, and further improve the reliability and the service life of the adapter.

In the following, the drive member 23 is exemplarily illustrated:

as shown in fig. 3, the actuator 23 is located on a side of the contact assembly 22 facing away from the contacts 220. The driver 23 is configured to push the contact assembly 22 such that the contacts 220 extend out of the power take-out housing 21 through the opening 210.

When the driving member 23 does not push the contact assembly 22, the contact assembly 22 can be driven by its own elastic force to drive the contact 220 to rebound to the inside of the electricity-taking housing 21 through the opening 210.

In some examples, the driving member 23 is slidably connected to the power take-out housing 21 along the inserting and extracting direction of the power take-out body 2. The drive member 23 has a raised portion facing the contact assembly 22. When the driving member 23 slides in the pull-out direction, the convex portion comes into contact with the contact assembly 22 and pushes the contacts 220 to gradually protrude out of the power take-out housing 21. When the driving member 23 slides in the insertion direction, the protruding portion gradually separates from the contact piece assembly 22, and the contact 220 gradually rebounds to the inside of the electricity-taking housing 21.

In some examples, the portion of the drive member 23 used to urge the contact blade assembly 22 is resilient. And, in the case that there is no external block for the contact 220, the maximum length that the driver 23 can push the contact 220 to protrude out of the power-taking housing 21 is L1, and when the driver 23 pushes the contact 220 to contact with the conductive sheet in the track, the length that the contact 220 protrudes out of the power-taking housing 21 is L2, where L1 is greater than L2.

In this way, the driver 23 is able to stroke compensate the contact 220 by a maximum stroke equal to the difference between L1 and L2. When the contact 220 is reduced in length due to abrasion, the driving member 23 can push the contact 220 to continue to extend, so that when the contact 220 is in contact with the conductive sheet in the track, the length L2 of the contact 220 does not decrease due to abrasion of the contact 220, and the contact 220 and the conductive sheet in the track can be always in close contact with each other, so that the reliability is high.

Of course, the portion of the driving member 23 for pushing the contact blade assembly 22 may have no elasticity, which is not limited by the embodiment of the disclosure.

In the following, the structure of the driving member 23 is exemplified by a specific example:

as shown in fig. 4 and 5, the driving member 23 includes a supporting member 231 and an elastic piece 232. The support 231 is slidably connected to the power take-out housing 21 along the inserting and extracting direction of the power take-out body 2. One part of the elastic sheet 232 is fixedly connected with the supporting piece 1, the other part of the elastic sheet 232 extends along the insertion direction of the power taking body 2 and is provided with a convex part 2321 protruding towards the contact piece assembly 22, and the convex part 2321 is used for pushing the contact piece assembly 22.

The supporting member 231 may be a plastic member. The elastic sheet 232 is elastic and may be a metal elastic sheet.

According to the technical scheme provided by the embodiment of the disclosure, the elastic sheet 232 with elasticity is used for pushing the contact piece assembly 22, so that the driving piece 23 can compensate the stroke of the contact 220, the contact of the contact 220 and a conducting sheet in a track can be tight, and the reliability is improved.

The embodiment of the present disclosure does not limit the position and the forming manner of the protruding portion 2321. In some examples, as shown in fig. 4 and 5, the protrusion 2321 is formed by tilting an end of the elastic piece 232 away from the support 231. In other examples, the protruding portion 2321 may be formed by bending a middle portion of the elastic sheet 232. In other examples, the protruding portion 2321 may be formed by adhering or welding a bump to a side of the body of the elastic piece 232 facing the contact piece assembly 22, for example, adhering a plastic block to a side of the elastic piece 232 facing the contact piece assembly 22 (the elastic force is provided by the elastic piece 232).

In addition, when the contact assembly 22 includes a plurality of contacts 221, the number of resilient pieces 232 is also plural. Moreover, the elastic pieces 232 should be capable of pushing the contacts 220 to extend out of the power taking housing 21, so when the contacts 220 are at different heights along the inserting and extracting direction of the power taking body 2, the protruding portions 2321 of the elastic pieces 232 are also at different heights, and the positions of the protruding portions 2321 correspond to the positions of the contacts 220 one to one.

The specific configuration of the supporting member 231 is exemplified as follows:

as shown in fig. 4 and 5, the support 231 includes a plate body portion 2311 and an operation portion 2312. The plate body 2311 is fixedly connected with the elastic sheet 232, and the plate body 2311 is slidably connected with the power taking shell 21. The operation portion 2312 is fixedly connected to the plate body portion 2311, and the operation portion 2312 protrudes relative to the plate body portion 2311 and is exposed outside the power taking housing 21. The operation portion 2312 may be a protrusion located on the plate body portion 2311.

The embodiment of the present disclosure does not limit the exposed position of the operation portion 2312 in the power taking housing 21.

In some examples, as shown in fig. 5 and 6, the operating portion 2312 is located on a side of the plate body portion 2311 away from the contact assembly 22, and is exposed at the first side wall 211 of the power-taking housing 21, where the first side wall 211 is opposite to the side wall (i.e., the second side wall 212) where the opening 210 is located. In the process of inserting the power-taking body 2 into the track, the track wall on the opening side of the track pushes the operating part 2312 to slide, so as to drive the driving part 23 to push the contact piece assembly 22.

Wherein, the operation portions 2312 may be two, and the two operation portions 2312 are flush, so that the rail wall may push the two operation portions 2312 at the same time, and the sliding of the driving member 23 is smoother.

By exposing the operation portion 2312 on the first side wall 211, the insertion of the adapter and the extension of the contact 220 out of the power-taking housing 21 are completed synchronously, and the operation of a user is simple and convenient.

In addition, as shown in fig. 6, by exposing the operation portion 2312 in the gap between the socket body 1 and the power take-out body 2, the operation portion 2312 is hard to be touched by the user in a state where the adapter is pulled out of the rail, thereby reducing the possibility that the contact 220 protrudes out of the power take-out housing 21 due to the user's mistaken touch.

Of course, the operation portion 2312 may be exposed at the other side wall of the power taking housing 21, which is not limited in the embodiment of the present disclosure.

In some examples, the operation portion 2312 may also be located on a surface of the plate body portion 2311 close to the contact assembly 22, and is exposed at the second sidewall 212 of the power-taking housing 21 (as shown in fig. 6, the second sidewall 212 is a sidewall where the opening 210 is located). In the process of inserting the power-taking body 2 into the track, the track wall on the side of the opening of the track also pushes the operating portion 2312 to slide, so as to drive the driving member 23 to push the contact assembly 22.

In addition, the insertion of the adapter and the extending of the contact 220 out of the power-taking housing 21 may not be completed at the same time, in other examples, the operation portion 2312 is exposed at the third side wall or the fourth side wall of the power-taking housing 21 (both the third side wall and the fourth side wall are perpendicular to the first side wall 211), and at this time, after the user inserts the adapter into the inside of the track, the user pulls the driving member 23 to push the contact piece assembly 22 by toggling the operation portion 2312, so that the contact 220 extends out of the power-taking housing 21.

In order to make the adapter free from external force, the contact 220 can automatically rebound to the inside of the power-taking housing 21 and can be stabilized in the inside of the power-taking housing 21, in some examples, as shown in fig. 7, the supporting member 231 further includes a spring mounting portion 2313, and the driving member 23 further includes a return spring 233. One end of the return spring 233 close to the protruding portion 2321 contacts the spring mounting portion 2313, one end of the return spring 233 far from the protruding portion 2321 contacts the inner wall of the power taking housing 21, and the return spring 233 is in a compressed state. The return spring 233 is configured to push the support 231 to slide so as to separate the boss 2321 from the contact blade assembly 22.

Wherein, the axial direction of the return spring 233 may be parallel to the sliding direction of the supporter 231. The return spring 233 is located on a side of the support 231 remote from the boss 2321.

According to the technical scheme provided by the embodiment of the disclosure, by arranging the return spring 233, when the adapter is pulled out from the rail, the return spring 233 can automatically push the supporting piece 231 to slide, so that the protruding portion 2321 is separated from the contact piece assembly 22, and then the contact 220 is automatically retracted into the electricity taking shell 21. The user does not need to carry out additional operation, and the operation is very convenient.

The number of the spring mounting portions 2313 and the number of the return springs 233 are not limited in the embodiment of the present disclosure, for example, as shown in fig. 7, two spring mounting portions 2313 and two return springs 233 are both provided, the two spring mounting portions 2313 are respectively located at two sides of the plate body portion 2311, and the two return springs 233 are respectively abutted to the two spring mounting portions 2313. Therefore, the stress of the supporting member 231 is more uniform, and the sliding of the supporting member 231 is smoother.

The form of the spring mounting portion 2313 is not limited in the embodiments of the present disclosure, and for example, as shown in fig. 8, the spring mounting portion 2313 includes a spring mounting plate 23131 and a spring mounting post 23132. The spring mounting plate 23131 abuts against the return spring 233. The spring mounting post 23132 is fixed to the plate surface of the spring mounting plate 23131 and extends into the interior of the return spring 233.

In order to stabilize the state in which the contact 220 protrudes out of the power taking housing 21, as shown in fig. 9 and 10, the plate body portion 2311 has a locking hole 23111 on the plate surface, and the adaptor further includes a locking piece 24. The locking hole 23111 may be a through hole or a blind hole, which is not limited in the embodiment of the present disclosure.

The lock 24 is configured to extend into the lock hole 23111 when the contact 220 extends out of the power take-out housing 21 through the opening 210. Thus, the lock member 24 can lock the driving member 23, so that the contact 220 can be stabilized in a state of being extended out of the electricity-taking housing 21.

The embodiment of the present disclosure does not limit the implementation manner of the locking member 24, and provides a possible implementation manner as follows:

as shown in fig. 11, the lock member 24 includes a lock rod 241, a lock spring 242, and an unlock member 243. The locking rod 241 is slidably connected to the inner wall of the power taking housing 21, the sliding direction of the locking rod 241 intersects with the sliding direction of the plate body 2311, and the locking rod 241 is used for extending into the locking hole 23111. One end of the locking spring 242 close to the plate body portion 2311 abuts against the locking lever 241, one end of the locking spring 242 far from the plate body portion 2311 abuts against the inner wall of the electricity taking housing 21, and the locking spring 242 is in a compressed state. The unlocking member 243 is fixedly connected to the locking rod 241, and the unlocking member 243 is exposed outside the socket housing 11, and the unlocking member 243 can drive the locking rod 241 to slide in a direction away from the plate portion 2311.

The sliding direction of the locking lever 241 may be perpendicular to the sliding direction of the plate body 2311.

The axis of the locking spring 242 is parallel to the sliding direction of the locking lever 241, and the locking spring 242 functions to push the locking lever 241 to be extended, so that the locking lever 241 can be stabilized in a state of being extended into the inside of the locking hole 23111.

The unlocking member 243 is used for driving the locking rod 241 to retract from the locking hole 23111 so as to release the locking state of the driving member 23, and the contact 220 can be smoothly rebounded to the inside of the electricity taking housing 21.

The operating principle of locking member 24 is:

when the contact 220 extends out of the power taking housing 21, the lock lever 241 extends into the lock hole 23111 by the urging force of the lock spring 242. The driving member 23 is locked, and the contact point 220 is stabilized in a state of being extended out of the electricity-taking housing 21.

When it is necessary to release the locked state of the driver 23, the unlocking member 243 is pushed against the elastic force of the locking spring 242 to retract the locking rod 241 from the locking hole 23111. The driving member 23 is unlocked and the contact 220 can be retracted into the power-taking housing 21 smoothly.

In order to automatically complete the locking action of the driving member 23 while the driving member 23 controls the contact 220 to extend out of the power-taking housing 21, in some examples, as shown in fig. 12, a side wall of the plate body portion 2311 for touching the locking lever 241 has a first guide inclined surface 23112, and the first guide inclined surface 23112 is inclined with respect to the sliding direction of the plate body portion 2311 and faces the locking lever 241. One end of the lock lever 241 near the plate body portion 2311 has a second guide slope 2410, and the second guide slope 2410 is inclined with respect to the sliding direction of the lock lever 241 and toward the first guide slope 23112. The first guide slope 23112 is configured to push the lock lever 241 to retract by the second guide slope 2410.

In the process that the driving member 23 pushes the contact 220 to extend out of the electricity-getting housing 21, the first guiding inclined surface 23112 of the plate body portion 2311 contacts with the second guiding inclined surface 2410, and the plate body portion 2311 pushes the locking lever 241 to gradually retract against the elastic force of the locking spring 242, and meanwhile, the plate body portion 2311 continues to move upwards. When the locking rod 241 is aligned with the locking hole 23111, the locking rod 241 is out of the block, and under the elastic force of the locking spring 242, the locking rod 241 extends into the locking hole 23111, so that the driving member 23 is locked. Meanwhile, the action of the driving member 23 to push the contact 220 to extend out of the power-taking housing 21 is also completed synchronously.

As shown in FIG. 13, to provide an exploded view of lockout member 24 in accordance with an embodiment of the present disclosure, lockout member 24 includes a lockout lever 241, a lockout spring 242, and an unlocking member 243.

The lock lever 241 includes a lock lever body 2411 and a first coupling portion 2412, the lock lever body 2411 having an opening 24111, the opening 24111 having a mounting post 24112 adjacent an inner wall of the actuator 23. The inner wall of the power-taking housing 21 may have a baffle 213 (as shown in fig. 11), and the baffle 213 may be located on a side of the opening 24111 away from the driving member 23. The locking spring 242 may be positioned in the opening 24111 with one end looped over the post 24112 and the other end abutting the stop 213. The first connection portion 2412 has a snap hole.

The unlocking member 243 includes a push button 2431 and a second connecting portion 2432, and one end of the second connecting portion 2432 is connected to the push button 2431 and the other end thereof has a catch. The buckle of the second connecting portion 2432 is in snap-fit connection with the snap-fit hole of the first connecting portion 2412. The push button 2431 is exposed on the outside of the receptacle housing 11 for pushing by a user.

The following, in conjunction with the above, illustrates the overall operation of the adapter:

during insertion of the adapter into the track, the track wall on the open side of the track pushes the handle 2312 to slide the entire drive member 23. During the sliding of the driving member 23, the protruding portion 2321 of the resilient tab 232 pushes the contact assembly 22, so that the contact 220 gradually protrudes from the opening 210.

While the protrusion 2321 pushes the contact piece assembly 22, the plate body 2311 pushes the locking lever 241 to retract until the locking lever 241 is opposite to the locking hole 23111 on the plate body 2311, and under the pushing force of the locking spring 242, the locking lever 241 extends into the locking hole 23111, so that the position of the driving member 23 is locked. Also, in this position the contact 220 extends out of the power take-off housing 21 and contacts a conductive sheet in the track. At this time, since the contacts 220 protrude out of the power taking housing 21, the adapter is not easily pulled out.

When it is desired to de-energize the adapter, the unlocking member 243 is pushed to retract the locking rod 241 from the locking hole 23111, and the driving member 23 is unlocked. Under the thrust action of the return spring 233, the support 231 drives the protruding portion 2321 of the elastic sheet 232 to move towards the direction away from the contact blade assembly 22, the contact 220 gradually retracts to the inside of the electricity taking housing 21, and the adapter is powered off. At this time, the adapter can be pushed to slide or pulled out from the rail.

The disclosed embodiment is not limited to the manner in which the receptacle assembly 12 is electrically connected to the contact assembly 22, and in some examples, the receptacle assembly 12 may be welded to the contact assembly 22, and in other examples, the receptacle assembly 12 may be connected to the contact assembly 22 by a jumper.

The following is an exemplary description of the structure of the receptacle assembly 12 and the contact assembly 22, taking the receptacle assembly 12 and the contact assembly 22 as an example:

as shown in fig. 14, the sleeve assembly 12 includes a plurality of sleeves 121, each sleeve 121 includes a sleeve body 1211 and a connecting piece 1212, and a first end of the connecting piece 1212 is connected to the sleeve body 1211. Contact assembly 22 includes a plurality of contacts 221, with contacts 220 on one face of contacts 221. Second ends of the connecting pads 1212 of the plurality of sleeves 121 are respectively welded to ends of the plurality of contact blades 221 remote from the contacts 220.

In the solution shown in the embodiment of the present disclosure, the plurality of sockets 121 in the socket assembly 12 are respectively welded to the plurality of contacts 221 in the contact assembly 22, so that the electrical connection between the socket assembly 12 and the contact assembly 22 is more stable.

To improve the stability of the soldering, in some examples, as shown in fig. 15, the second end of the connecting pad 1212 has a soldering hole 12120, and the end of the contact blade 221 away from the contact 220 has a tab 22140, and the tab 22140 extends into and is soldered in the soldering hole 12120.

Of course, in other examples, the second end of the connecting pad 1212 may have a fin, and the end of the contact blade 221 away from the contact 220 may have a solder hole, into which the fin extends and is soldered.

The embodiment of the present disclosure does not limit the specific form of the insert sleeve 121. In some examples, the insert 121 may be formed by integral bending. When the plug bush 121 is manufactured, firstly, a metal plate is punched to obtain strip-shaped bending pieces, and then the bending pieces are bent to obtain the plug bush 121.

Compared with the conventional plug bush, the plug bush 121 provided by the embodiment of the disclosure is additionally provided with the connecting piece 1212, the increase of the connecting piece 1212 inevitably leads to the increase of the material consumption of the plug bush 121, and the plug bush 121 provided by the embodiment of the disclosure can increase the material consumption of the plug bush 121 little through reasonable structural design, so that the utilization rate of the material consumption is improved.

The following description exemplifies specific forms of the insert sleeve 121, taking the insert sleeve 121 as an L-pole insert sleeve, an N-pole insert sleeve, and an E-pole insert sleeve, respectively:

as shown in fig. 16, the insert 121 is an L-pole insert or an N-pole insert. The plug body 1211 includes a first main current carrying chip 12111 and two first clamping chip pairs 12112, and the two first clamping chip pairs 12112 are connected to one side of the first main current carrying chip 12111. The connecting piece 1212 includes a first connecting section 12121 and a second connecting section 12122 connected.

The first connecting section 12121 is located on the same side of the first main current tab 12111 as the first pair of tabs 12112, and the first connecting section 12121 is located between the two first pairs of tabs 12112 and is bent away from the E-pole plug wrap with respect to the first main current tab 12111.

The second connection section 12122 is located on the same side of the first connection section 12121 as one of the first pair of clip tabs 12112 and on a different side of the first connection section 12121 from the other of the first pair of clip tabs 12112. The first connection section 12121 and the second connection section 12122 may be in the same plane and perpendicular to each other. And, the second connecting section 12122 is contracted with respect to the first main carrier sheet 12111 in the unfolded state. The second connection section 12122 may have solder apertures 12120.

As shown in fig. 17, a layout diagram corresponding to the L-pole plug bush or the N-pole plug bush of the above structure is shown. As can be seen from the layout diagram, the addition of the connecting piece 1212 does not increase the material consumption of the plug sleeve 121 too much, and the material consumption of the plug sleeve 121 is high.

Specifically, the connecting piece 1212 is located between the two first clamping piece pairs 12112 and is shorter than the sleeve body 1211 in the length direction, so that the material is not added to the connecting piece 1212 in the length direction.

Since the connecting pad 1212 is located on the same side of the first main current tab 12111 as the pair of first clamping tabs 12122, there is no excessive increase in material in the width direction.

As shown in fig. 18, the insert 121 is an E-pole insert. The plug body 1211 includes a second main current carrying chip 12113 and a second pair of holding chips 12114, and the second pair of holding chips 12114 is connected to one side of the second main current carrying chip 12113. The connecting piece 1212 includes a third connecting segment 12123, a fourth connecting segment 12124, and a fifth connecting segment 12125 connected thereto. The third connecting segment 12123 is located on the same side of the second main current tab 12113 as the second pair of clip tabs 12114. The fourth connecting segment 12124 is located on the side of the third connecting segment 12123 distal from the second pair of clamping tabs 12114. Fifth connecting segment 12125 is located on a side of fourth connecting segment 12124 away from second main current carrying tab 12113.

As shown in fig. 19, a layout corresponding to the E-pole insert sleeve of the above structure is shown. As can be seen from the layout diagram, the addition of the connecting piece 1212 does not increase the material consumption of the plug sleeve 121 too much, and the material consumption of the plug sleeve 121 is high.

Specifically, since the connecting pad 1212 is located on the same side of the second main current tab 12113 as the second pair of clamping tabs 12114, there is no excessive increase in material in the width direction.

Also, fourth connecting segment 12124 is located on a side of third connecting segment 12123 away from second pair of tabs 12114 and fifth connecting segment 12125 is located on a side of fourth connecting segment 12124 away from second main current tab 12113, as shown in fig. 19, so that the corresponding discharges of the E-pole insert pocket do not have excessive added material in the length direction. In addition, in the discharge corresponding to two adjacent E pole plug bushes, the fifth connecting section 12125 of one E pole plug bush can extend into the notch c of the other E pole plug bush, so that the material consumption of the E pole plug bushes in the width direction is further reduced.

In some examples, the fifth connecting segment 12125 is bent relative to the fourth connecting segment 12124 and perpendicular to each other. The fifth connection section 12125 may have solder holes 12120.

In order to make the contact assembly 22 more stable inside the electricity-taking housing 21, as shown in fig. 20, the contact assembly 22 further includes an adhesive-coated plate 222. The encapsulating plate 222 fixes the plurality of contacts 221 together, and the encapsulating plate 222 is fixedly connected with the power-taking housing 21.

Wherein the contacts 220 are not covered by the encapsulation plate 222.

The embodiment of the present disclosure does not limit the position of the contact 221 covered by the encapsulating plate 222. In some examples, the end of the contact blade 221 distal from the contact 220 should be exposed for welding with the jack assembly 12. In addition, a section of the contact 220 should be exposed, so that the contact 220 is in a suspended state inside the power-taking housing 21, and the contact 220 is more easily pushed by the driving member 23.

Illustratively, as shown in fig. 21, the contact sheet 221 includes a flying section 2211, a first fixed section 2212, a second fixed section 2213 and a connecting section 2214 connected in sequence. The end of the overhanging section 2211 away from the first fixed section 2212 has a contact 220, the second fixed section 2213 is bent towards the plug bush assembly 12 relative to the first fixed section 2212, and the connecting section 2214 is welded with the contact piece 221.

The adhesive coating plate 222 coats the first fixing section 2212 and the second fixing section 2213, and the suspension section 2211 is suspended inside the power taking shell 21, so that the suspension section 2211 is more easily pushed by the driving member 23.

The first fixing segment 2212 may be parallel to a plugging direction of the power taking body 2, and the second fixing segment 2213 may be perpendicular to the first fixing segment 2212.

The disclosed embodiment also provides a rail socket, as shown in fig. 22, which includes a rail a and an adapter b.

When the adapter b is in the power-taking state, the contact 220 of the adapter b extends out of the power-taking housing 21 and contacts the conductive sheet in the track a.

When adapter b is in the power-off state, contacts 220 of adapter b retract into power-taking housing 21, separating from the conductive strips in track a.
