With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below.

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.

As shown in fig. 1, the rail socket is a mobile socket, and includes a rail 1 and an adapter 2, and the adapter 2 can be assembled at different positions of the rail 1 to take power.

In the following, the adapter and the rail provided by the embodiment of the present disclosure are respectively explained:

the embodiment of the present disclosure provides an adapter, as shown in fig. 2, the adapter includes a socket body 11, a power-taking body 12, and a protection body 13. The socket body 11 is fixedly connected with the power-taking body 12, and a gap 10 for accommodating a wall of the rail is formed between the socket body 11 and the power-taking body 12. The power extractor 12 has a contact 122 at a first casing wall 121a, and the first casing wall 121a is any one of two casing walls opposite to the socket body 11. The shield 13 is slidably connected to the power extractor 12, and the shield 13 is located on the first housing wall 121a and can cover or expose the contact 122 by sliding.

When the adapter provided by the embodiment of the present disclosure requires power, as shown in the left half of fig. 2, the control shield 13 slides away from the contact 122 to expose the contact 122, so that the contact 122 can contact a bus bar in the track and take power from the bus bar.

As shown in the right half of fig. 2, when the adapter does not need to be powered, for example, when the adapter is pulled out of the track, the shield 13 can be controlled to slide toward the contact 122 until the contact 122 is shielded, and the possibility that the contact 122 is abraded is reduced, so that the reliability and the service life of the adapter are improved.

It should be noted that the first housing wall 121a shown in fig. 2 is the housing wall far from the socket body 11 of the two housing walls opposite to the socket body 11, and in practical applications, the first housing wall 121a may also be the housing wall near the socket body 11 of the two housing walls opposite to the socket body 11. The drawings provided by the embodiments of the disclosure only illustrate the first housing wall 121a as the housing wall far from the socket body 11.

In the following, various components of the adapter provided by the embodiments of the present disclosure are exemplarily described:

the socket body 11 is used for mating with a plug. The socket body 11 includes a socket housing and a plug bush, the plug bush is fixed inside the socket housing, and the plug bush is electrically connected to the contact 122. The part of the socket shell corresponding to the plug bush is provided with a jack for inserting the plug. In addition, the socket body 11 may further include a protective door assembly located inside the socket housing and blocking the insertion holes.

The power taking body 12 is used for extending into the track to take power, and the power taking body 12 can also be called an inserting sheet, a hanging sheet and the like. The power take-off 12 has contacts 122, the contacts 122 being for contact with a conductive strip in the track.

The shield 13 is configured to shield the contact 122, and in particular, to shield the contact 122 in the power-off state, thereby reducing the possibility of the contact 122 being worn. The protective body 13 is connected with the electricity-taking body 12 in a sliding way.

In the following, the protective body 13 is illustrated in more detail:

the sliding direction of the protecting body 13 is not limited in the embodiments of the present disclosure, and in some examples, as shown by the direction indicated by the arrow in fig. 2, the sliding direction of the protecting body 13 is parallel to the direction in which the power take-off body 12 is inserted into the track.

As shown in fig. 3, during the process of inserting the power-taking body 12 into the track, the raised strips 211 of the track push the shielding body 13 to slide, so as to expose the contact piece 122.

According to the technical scheme provided by the embodiment of the disclosure, as shown in fig. 3 and 4, by the design, when the adapter is inserted into the track, the protruding strip 211 automatically pushes the protective body 13 to slide towards the direction away from the contact piece 122, and the contact piece 122 is exposed. The user does not need extra action to operate the protection body 13 independently, and the operation is simple and convenient.

Of course, the above is only one possible example. In practical applications, the protecting body 13 and the power-taking body 12 can be connected in a sliding manner along other directions, and the action of inserting the power-taking body 12 into the track and the action of sliding the operation protecting body 13 can be two actions. For example, the user may first operate shield 13 to slide away from contacts 122 and expose contacts 122, and then insert the adapter into the track.

The embodiment of the present disclosure does not limit the specific structure of the protection body 13, and the following provides a possible implementation form:

as shown in fig. 5, the shield body 13 includes a shield door 131 and a first elastic member 132. The protective door 131 is slidably connected to the power take-off body 12, and the protective door 131 is located on the first housing wall 121 a. The first elastic member 132 is located inside the power take-off body 12, one end of the first elastic member 132 away from the contact piece 122 abuts against the inner wall of the power take-off body 12, the other end abuts against the protective door 131, and the first elastic member 132 is in a compressed state.

Wherein, the first elastic member 132 may be a spring. The number of the first elastic members 132 may be two, so that the force applied to the protective door 131 is more uniform.

According to the technical scheme provided by the embodiment of the disclosure, the first elastic member 132 is arranged, so that the protective body 13 can automatically shield the contact piece 122 without external force, the user does not need to specially operate the protective body 13 to shield the contact piece 122, and the possibility that the contact piece 122 is exposed due to forgetting operation by the user is reduced.

Of course, the above shield body 13 including the shield door 131 and the first elastic member 132 is only an example. In practical applications, it is also possible to arrange that the protective body 13 does not include the first elastic member 132, and the protective door 131 can be actively operated by a user to shield or expose the contact 122. In addition, in this case, when the protective door 131 covers the contact piece 122, the protective door 131 and the power-taking body 12 can be synchronously clamped, so that the protective door 131 is stable.

The specific form of the protective door 131 is not limited in the embodiments of the present disclosure, and in some examples, as shown in fig. 6, there are a plurality of contacts 122, and the plurality of contacts 122 are diagonally distributed on the first housing wall 121 a. The end of the protective door 131 close to the contacts 122 is in a multi-step shape, the number of the step steps is the same as that of the contacts 122, and the protective door 131 can synchronously shield or expose a plurality of contacts 122.

In some examples, as shown in fig. 6, there are three contacts 122, i.e., L-pole, N-pole and E-pole contacts, and the shield door 131 has three steps near the end of the contacts 122.

In other examples, where there are two contacts 122, an L-pole contact and an N-pole contact, the guard door 131 has two steps near the end of the contact 122.

As shown in fig. 7, the protection door 131 includes a plate body 1311, a second mounting post 1312, and a stopper 1313. The second mounting post 1312 and the stopper 1313 may be two each.

Two second mounting posts 1312 are fixed to an end of the plate 1311 away from the contact 122 and are spaced apart from each other. The second mounting post 1312 is used to extend into one end of the first elastic member 132, so that the first elastic member 132 is more stable. In addition, a mounting post may be disposed at the power-taking housing 121, and the mounting post extends into the other end of the first elastic member 132.

The two limiting blocks 1313 are fixed to two sides of the board 1311, and are used for matching with an inner wall of the power taking housing 121 to prevent the protective door 131 from completely separating from the power taking housing 121.

Next, a specific structure of the current collector 12 will be exemplarily described:

in some examples, as shown in fig. 8, the power take-off body 12 includes a power take-off housing 121, a contact piece 122, and a second elastic piece 123. The first wall 121a of the power-taking housing 121 has an opening 120. Contacts 122 are located in the openings 120. One end of the second elastic member 123 abuts against the electricity-getting housing 121, and the other end abuts against the contact piece 122.

As shown in fig. 9, in the power-off state, the contact 122 is blocked by the shield 13, and in the power-on state, the second elastic member 123 drives the contact 122 to extend out of the power-on housing 121.

When the adapter is inserted into the track, the raised strips 211 of the track push the shield 13 to move away from the contact 122 until the shield 13 no longer blocks the contact 122, and then the contact 122 extends out of the power-taking housing 21 and contacts with the bus bar in the track under the driving of the second elastic member 123.

As the adapter is pulled out of the track, shield 13 gradually moves toward contact 122 as it gradually moves away from rib 211. When the shield 13 contacts the contact piece 122, the shield 13 drives the contact piece 122 to retract into the inside of the power-taking housing 121 against the elastic force of the second elastic member 123.

The technical scheme that this disclosure provided is connected with contact 122 through setting up second elastic component 123 for under the outage state, contact 122 can contract to the inside of getting electric casing 121 under the effect of protective body 13, and under the state of getting electric, second elastic component 123 can promote contact 122 and stretch out and get electric casing 121.

And, the contact piece 122 is more closely contacted with the conductive strip of the track under the pushing of the second elastic member 123. Also, when the contact piece 122 is reduced in length due to wear, the second elastic member 123 may continue to extend and push the contact piece 122 into close contact with the bus bar.

Furthermore, the travel of the contact piece 122 is longer, so that the conducting strip 22 can be better hidden in the track shell 21, and the safety of the track socket is higher.

To facilitate shield 13 driving contact 122 back, in some examples, as shown in fig. 9, the side of shield 13 facing extractor 12 has a guide ramp 130. The guiding inclined plane 130 is adjacent to the end of the shield 13 close to the contact 122, and the distance between the guiding inclined plane 130 and the power-taking body 12 gradually decreases along the direction away from the end. Wherein the guide slope 130 is located on the guard door 131.

In some examples, as shown in fig. 9, the end surface of shield 13 near contact 122 transitions in an arc with guide ramp 130.

The specific structure of the contact 122 is not limited in the embodiments of the present disclosure, and in some examples, as shown in fig. 10, the contact 122 includes a first contact segment 1221, a second contact segment 1222, and a third contact segment 1223 connected in sequence, where the first contact segment 1221 is opposite to the third contact segment 1223. The first contact section 1221 is intended to be in contact with a conductor strip in a track, the connection portion 1220 of the first contact section 1221 and the second contact section 1222 is in an arc-shaped transition, and the connection portion 1220 is intended to be in contact with an end of the shield 13. The third contact section 1223 abuts against the second resilient member 123.

According to the technical scheme provided by the embodiment of the disclosure, the connecting portion 1220 provided with the first contact piece segment 1221 and the second contact piece segment 1222 is in arc transition, so that when the protective body 13 touches the connecting portion 1220, the protective body 13 can push the contact piece 122 to retract more smoothly.

As shown in fig. 10, the second resilient member 123 is a spring, and the contact 122 further includes a first mounting post 1224. First mounting post 1224 is connected at one end to third contact section 1223 and extends into the interior of second resilient member 123 at the other end.

According to the technical scheme provided by the embodiment of the present disclosure, the first mounting post 1224 is additionally arranged on the third contact section 1223, and the first mounting post 1224 extends into the second elastic member 123, so that the second elastic member 123 is more stable.

In some examples, in order to make the end of the second elastic element 123, which abuts against the power-taking housing 121, more stable, as shown in fig. 9, a wall of the power-taking housing 121 opposite to the first wall 121a has a third mounting column 124, and the third mounting column 124 extends into the second elastic element 123.

It should be noted that the above power take-off body 12 including the power take-off housing 121, the contact piece 122, and the second elastic member 123 is merely an example. In practical applications, the power take-off body 12 may only include the power take-off housing 121 and the contact 122, and the contact 122 protrudes from the power take-off housing 121. In this case, the shield 13 does not touch the contact piece 122 during the sliding.

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

when the adapter is needed to take power:

the adapter is inserted into the track, and when the guard door 131 is not yet in contact with the convex strip 211 of the track, the guard door 131 shields the contact piece 122 under the pushing of the first elastic member 132.

When the end of the shutter 131 contacts the raised strip 211 of the track, and the adapter is inserted, the raised strip 211 pushes the shutter 131 to slide away from the contact 122.

When the protective door 131 slides to no longer block the contact piece 122, the contact piece 122 extends out of the power-taking housing 21 and contacts with the bus bar in the track under the driving of the second elastic member 123.

When adapter power down is required:

the adapter is pulled out of the track and the shutter 131 slides toward the contact 122 under the urging of the first resilient member 132.

Continuing to withdraw the adapter, the shutter door 131 contacts the contact piece 122, and under the driving force provided by the first elastic member 132, the shutter door 131 pushes the contact piece 122 to retract gradually against the elastic force of the second elastic member 123.

The protective door 131 continues to slide by the first elastic member 132 until the first elastic member 132 is in an ultimate extension state.

After the process is completed, the adapter is not yet completely pulled out of the rail, the adapter can be completely pulled out of the rail at the moment, or the adapter can be inserted into the rail after the adapter is slid to a proper position in the rail.

It should be added that, since the socket is fixed inside the socket housing and the contact piece 122 can move relative to the power-taking housing 121, the contact piece 122 can move relative to the socket. Thus, the electrical connection between the receptacle and the contacts 122 may be through a flexible jumper, such that the jumper is able to accommodate movement of the contacts 122 relative to the receptacle by flexing.

The disclosed embodiment also provides a track, as shown in fig. 11, for docking the above-mentioned adapter, the track comprising a track housing 21 and a conductive strip 22. The conductive strip 22 is fixed to the inside of the second wall 21a of the track housing 21. The inner side of the second shell wall 21a has a protruding strip 211, the protruding strip 211 extends along the same direction as the conductive strip 22, and the protruding strip 211 is used for pushing the protective body 13 of the adapter to slide towards the direction away from the contact piece 122.

The track housing 21 is used for supporting and protecting the conductive strip 22, and the track housing 21 has an opening 20, and the opening 20 is extended in the same direction as the conductive strip 22 for inserting the power-taking body 12 of the adapter 1.

As shown in fig. 11, there may be three conductive strips 22, which are an L-pole conductive strip, an N-pole conductive strip and an E-pole conductive strip, and the three conductive strips 22 are distributed in sequence along the insertion direction of the adapter into the track.

The ribs 211 extend in the same direction as the conductive strips 22 so that the ribs 211 push the shield 13 to slide away from the contact 122 no matter where the adapter is inserted from the track.

The protruding strip 211 may be located between two conductive strips 22 away from the opening 20, the protruding strip 211 being used to push the most protruding portion of the end of the guard door 131.

The embodiment of the present disclosure further provides a rail socket, as shown in fig. 1, the rail socket includes the above adapter 1 and the above rail 2.

As shown in fig. 3 and the left half of fig. 9, when the guard door 131 is not in contact with the convex strip 211 of the track 2 during the insertion of the adapter 1 into the track 2, the guard door 131 shields the contact piece 122 under the driving of the first elastic member 132. Then, when the protective door 131 contacts the protruding strip 211, the protective door 131 moves in a direction away from the contact piece 122 under the pushing of the protruding strip 211, and the contact piece 122 is gradually exposed.

As shown in fig. 4 and the right half of fig. 9, the contact piece 122 loses the blocking of the guard door 131, and the contact piece 122 extends to the outside of the power-taking housing 121 and contacts the conductive bar 22 in the track 2 under the driving of the second elastic member 123, so that the adapter 1 is electrified.
