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 socket is common power supply equipment and is used for inserting plugs, adapters and other power taking parts of various electrical appliances. The sockets include various types such as rail sockets, panel sockets, and the like. The adapter provided by the embodiment of the disclosure can be applied to various sockets such as a track socket and a panel socket.

Fig. 1 is an exploded view of an adapter provided in an embodiment of the present disclosure, and as shown in fig. 1, the adapter includes a plug pin assembly 1, a housing 2, and a resilient assembly 3.

One part of the latch assembly 1 is located inside the housing 2 and the other part is located outside the housing 2 and is movable relative to the housing 2. The resilient member 3 is compressed between the latch member 1 and the inner wall of the housing 2.

The elastic component 3 is configured to contact the plug bush of the socket and keep the plug pin component 1 at the first position when the plug pin component 1 is triggered to the first position of the shell 2; when the latch assembly 1 is actuated to the second position of the housing 2, the latch assembly 1 is spaced from the socket of the receptacle and remains in the second position.

To more clearly describe the manner in which the adapter is used, the manner in which the adapter is assembled to the rail receptacle 100 will be described with reference to fig. 2. Fig. 2 is a schematic view showing the assembly of the adaptor to the rail socket, and as shown in fig. 2, the rail socket 100 has an elongated slide hole 110 which penetrates through the top surface of the rail socket 100 and extends along the length direction of the rail socket 100. Accordingly, the socket 120 is a strip-shaped socket. The plug pin assembly 1 of the adapter is inserted into the sliding hole 110 from the opening of the end of the rail socket 100, so that the plug pin assembly 1 can take electricity in the rail socket 100. The panel socket is common and therefore not described herein.

The manner of use of the adapter is described below in connection with fig. 3 and 4.

Fig. 3 is a schematic diagram of the power-getting state of the adapter, referring to fig. 3, if the adapter needs to get power from the socket, the plug pin assembly 1 is moved to the first position, and at this time, the portion of the plug pin assembly 1 located outside the housing 2 contacts with the plug bush 120 of the socket, and the adapter is in the power-getting state. In addition, under the action of the elastic component 3, the plug pin component 1 can be kept at the first position, so that the plug pin component 1 can be always kept in contact with the plug bush 120 of the socket, namely, the adapter can be stably powered.

Fig. 4 is a schematic diagram of the adapter in the non-power-taking state, referring to fig. 4, if the adapter does not need to take power from the socket, the plug pin assembly 1 is moved to the second position, and at this time, the portion of the plug pin assembly 1 located outside the housing 2 is spaced from the plug bush 120 of the socket, and the adapter is in the non-power-taking state. In addition, the plug pin assembly 1 can be kept at the second position under the action of the elastic assembly 3, so that the interval between the plug pin assembly 1 and the plug bush 120 of the socket can be always kept, namely, the stable power-off of the adapter is realized.

That is, when the latch assembly 1 is in the first position, the adapter is in the power-on state. When the bolt assembly 1 is in the second position, the adapter is in a non-power-taking state. Therefore, when the adapter is idle, the adapter does not need to be detached from the socket, and only the plug pin assembly 1 needs to be adjusted to the second position, and the plug pin assembly 1 and the plug bush 120 of the socket are always spaced under the action of the elastic assembly 3, that is, the power-off state of the adapter is kept. Therefore, potential safety hazards are eliminated, and the use convenience of the adapter is improved.

As mentioned above, the present disclosure provides an adapter that can be adapted to either a rail receptacle 100 or a panel receptacle. The two kinds of sockets are taken as examples, and the insertion manner of the adapter will be described below.

For the track socket 100, since the adapter needs to move along the length direction of the track socket 100, when the adapter is in the non-power-taking state, only the plug pin assembly 1 is no longer in contact with the plug bush 120 of the socket, and the whole adapter is still installed on the track socket 100, so that the adapter can move to other required positions along the length direction of the track socket 100. To achieve this, the bottom surface (the surface facing the track panel) of the housing 2 has a catch 23, and the catch 23 is inserted into the slide hole 110 from the opening at the end of the track socket 100, as in the plug assembly 1, so that the catch 23 is movably located in the track socket 100. Furthermore, the buckle 23 is in sliding contact with the plate surface where the sliding hole 110 is located, and the size is larger than the pitch of the sliding hole 110, so that the plug pin assembly 1 can stably slide without deviating from the rail socket 100 even if not in contact with the plug bush 120 of the socket.

For the panel socket, because the adapter is fixed in position on the panel socket, the requirement of moving does not exist, so when the adapter is in the non-power-taking state, only need guarantee that the adapter does not break away from the panel socket can. Therefore, the structure of the clip 23 can be simplified to reduce the production cost of the adapter.

From the foregoing, the switching between the power-taking state and the non-power-taking state of the adapter is mainly realized by the cooperation between the plug pin assembly 1 and the elastic assembly 3. Therefore, referring next again to fig. 1, the bayonet assembly 1 and the spring assembly 3 will be described.

In this embodiment, the latch assembly 1 includes a moving latch 11 and a toggle button 12. The moving bolt 11 is extended relative to the housing 2 and is movable relative to the housing 2, and the toggle button 12 is partly located outside the housing 2 and partly located inside the housing 2 and connected to the moving bolt 11, and the toggle button 12 is movable relative to the housing 2.

When the movable plug 11 is extended with respect to the housing 2 and comes into contact with the socket 120 of the socket, the adapter is in the power-on state. When the movable pin 11 is retracted relative to the housing 2 and spaced from the socket 120, the adapter is in a non-powered state. Since the toggle button 12 is partially located outside the housing 2, the user can easily dial. The user makes the movable bolt 11 move relative to the housing 2 by toggling the toggle button 12 which extends out of the housing 2, thereby realizing the switching between the power-taking state and the non-power-taking state of the adapter.

The elastic component 3 comprises two springs 31 respectively located on two sides of the moving direction of the toggle button 12, a first end of the spring 31 is connected to the toggle button 12, and a second end of the spring 31 is connected to the inner side wall of the housing 2.

The direction of movement of the toggle button 12 is the direction of movement of the latch assembly 1 when switching between the first and second positions. During the process of moving the moving bolt 11 relative to the housing 2 by the toggle button 12, the direction of the elastic force of the spring 31 changes. When the moving bolt 11 is extended relative to the housing 2 and contacts the socket 120 of the socket, the bolt assembly 1 is in the first position. At this time, the elastic force direction of the spring 31 is directed to the extending direction of the movable plug 11, so that the movable plug 11 can be pressed against the plug bush 120 of the socket by the elastic force, i.e. the plug pin assembly 1 is kept at the first position, and the adapter normally takes out power. Conversely, when the movable bolt 11 is retracted relative to the housing 2 and spaced from the socket 120, the bolt assembly 1 is in the second position. The direction of the spring force of the spring 31 now points in the direction of retraction of the moving bolt 11, so that the bolt assembly 1 can be held in the first position by the spring force and the adapter is de-energized.

The positions of the spring 31 in the power-on state and the power-off state will be described with reference to fig. 5 and 6, respectively.

FIG. 5 is a schematic diagram of the position of the spring when the adapter is in the power-on state. Referring to fig. 5, when the latch assembly 1 is triggered to the first position, the first end of the spring 31 is located below the second end with respect to the same horizontal plane.

In the above implementation, since the first end of the spring 31 is located below the second end, the elastic force of the spring 31 acting on the toggle button 12 is downward, i.e. directed to the extending direction of the moving latch 11, so that the latch assembly 1 is maintained in the first position.

FIG. 6 is a schematic diagram of the position of the spring when the adapter is not powered. Referring to fig. 6, when the latch assembly 1 is triggered to the second position, the first end of the spring 31 is located above the second end with respect to the same horizontal plane.

Based on the same principle, since the first end of the spring 31 is located above the second end, the spring force of the spring 31 acting on the toggle button 12 is upward, i.e. directed in the retracting direction of the moving latch 11, so that the latch assembly 1 is maintained in the second position.

It should be noted that the above implementation utilizes the neutral uncertainty of the spring 31. Therefore, based on similar principles, in other embodiments, a metal dome with certain flexibility may be used as the elastic component 3, and the toggle button 12 is connected to the middle of the metal dome. When the bolt component 1 is in the first position state, the middle part of the metal elastic sheet is sunken downwards, and the middle part of the metal elastic sheet keeps sunken downwards under the action of the elastic force of the metal elastic sheet, so that the bolt component 1 is kept at the first position, and the adapter normally takes electricity. On the contrary, when the plug pin assembly 1 is in the second position state, the middle part of the metal elastic sheet protrudes upwards, and the middle part of the metal elastic sheet keeps protruding upwards under the action of the elastic force of the metal elastic sheet, so that the plug pin assembly 1 is kept in the second position, and the adapter normally takes electricity.

Fig. 7 is a schematic view of the toggle button 12, and the toggle button 12 will be described with reference to fig. 7.

In this embodiment, the toggle button 12 comprises a connecting arm 121 and an operating plate 123, the connecting arm 121 having one end connected to the moving latch 11 and connected to a first end of the spring 31 and the other end protruding relative to the housing 2 and connected to the operating plate 123.

In the above implementation, the connecting arm 121 is used to function as a connecting operation plate 123 and the moving latch 11. And the operation panel 123 is located outside the housing 2 to facilitate the user to toggle, so that the operation panel 123 can drive the moving latch 11 to move through the connecting arm 121.

Alternatively, the connecting arm 121 is disposed perpendicular to the moving direction of the moving latch 11, and the operating plate 123 is disposed perpendicular to the connecting arm 121. That is, when the moving latch 11 moves, the operation plate 123 may move synchronously along the moving direction of the moving latch 11, thereby preventing interference between the moving latch and other components.

In this embodiment, the toggle button 12 further includes two first mounting seats 122, the two first mounting seats 122 are both located on the connecting arm 121 and are respectively located on two sides of the moving direction of the toggle button 12, and the first end of the spring 31 is connected to the connecting arm 121 through the first mounting seat 122.

Since the outer wall of the connecting arm 121 is a smooth plane, the first end of the spring 31 is not easily connected to the connecting arm 121. Therefore, a first mounting seat 122 is provided on the connecting arm 121, and the first mounting seat 122 is used for providing a mounting base for the first end of the spring 31, so that the first end of the spring 31 can be stably mounted on the connecting arm 121.

The positions of the two first mounting seats 122 on the connecting arm 121 are symmetrical about the axis of the connecting arm 121, which enables the elastic force of the two springs 31 acting on the connecting arm 121 to be more concentrated, so as to better apply the elastic force on the connecting arm 121.

In this embodiment, the first mounting seat 122 comprises a base 1221 and a pin 1222, the base 1221 is located on the connecting arm 121, the pin 1222 is located on the base 1221 away from the connecting arm 121, the pin 1222 is perpendicular to the moving direction of the toggle button 12, and the pin 1222 is inserted in the spring 31.

The base 1221 is used for bearing the elastic force of the spring 31, and the pin 1222 is used for fixing the spring 31 to prevent the spring 31 from falling out of the first mounting seat 122. Because no matter bolt subassembly 1 is in primary importance or second place, spring 31 all the time is in compression state, so the suit that spring 31's first end can stabilize all the time is on round pin 1222, the problem that the pine takes off can not appear, has guaranteed the reliability of adapter.

In other embodiments, the pin 1222 may be replaced by a recess in the base 1221 at a location away from the connecting arm 121, and the first end of the spring 31 is inserted into the recess. Due to the elasticity of the spring 31, the second end of the spring 31 will always be inserted in the recess, and a secure connection of the first end of the spring 31 to the connecting arm 121 is also achieved.

Optionally, the base 1221 is a triangular prism, an axial direction of the base 1221 is perpendicular to the moving direction of the toggle button 12, a side surface of the base 1221 is located on the connecting arm 121, and a portion of the base 1221 facing away from the connecting arm 121 abuts against the spring 31.

In addition to the side of the base 1221 that is located on the connecting arm 121, the base 1221 comprises an upper side that is arranged towards the top side of the housing 2 and a lower side that is arranged towards the bottom side of the housing 2. Setting the base 1221 to a triangular prism ensures stable compression of the spring 31 when the latch assembly 1 is in the first and second positions. For example, when the latch assembly 1 is located at the first position, the first end of the spring 31 is located below the second end, and at this time, the first end of the spring 31 abuts against the upper side of the base 1221, so that the contact area between the spring 31 and the base 1221 is increased by using the upper side, and the stability of the spring 31 on the first mounting seat 122 is improved. Based on the same principle, when the latch assembly 1 is located at the second position, the first end of the spring 31 is located above the second end, and at this time, the first end of the spring 31 abuts against the lower side surface of the base 1221, so that the contact area between the spring 31 and the base 1221 is increased by using the lower side surface, and the stability of the spring 31 on the first mounting seat 122 is improved.

In addition, the portion of the base 1221 facing away from the connecting arm 121 may be an outer chamfer 1223, so that when the latch assembly 1 is switched between the first position and the second position, the first end of the spring 31 can swing relative to the base 1221, which facilitates the switching between the upper side and the lower side of the first end of the spring 31.

The first end of the spring 31 is described above in connection with fig. 7 to achieve a secure mounting on the connecting arm 121 using the first mounting seat 122. Referring again to fig. 6, the manner in which the second end of the spring 31 is mounted on the inner wall of the housing 2 will now be described.

In the present embodiment, the inner wall of the housing 2 has two second mounting seats 21, the two second mounting seats 21 are respectively disposed opposite to the two first mounting seats 122, and the second end of the spring 31 is connected to the inner wall of the housing 2 through the second mounting seats 21.

Since the inner wall of the housing 2 is also a smooth flat surface, the second end of the spring 31 is not easily attached to the inner wall of the housing 2. Therefore, a second mounting seat 21 is provided on the inner wall of the housing 2, and the second mounting seat 21 is used for providing a mounting base for the second end of the spring 31, so that the second end of the spring 31 can be stably mounted on the inner wall of the housing 2. The structure of the second mounting seat 21 may be the same as that of the first mounting seat 122, and thus, the description thereof is omitted.

From the foregoing, it can be seen that the movable plug 11 is used for taking power in the socket, i.e. for electrically connecting the socket 120 of the socket with the socket 4 of the adapter. The moving latch 11 will now be described with reference to figure 8.

Fig. 8 is a schematic structural diagram of a moving latch, and in this embodiment, the moving latch 11 includes a sliding seat 111, a blade 112 and a contact 113. One part of the sliding seat 111 is positioned outside the shell 2, the other part is positioned inside the shell 2 and can move relative to the shell 2, and the inserting sheet 112 is positioned on the sliding seat 111 and is used for inserting the inserting sleeve 4 of the adapter; contacts 113 are located on slider 111 and are connected to blades 112, contacts 113 for contacting sleeves 120 of the receptacle.

In the above implementation, the male tab 112 can be separated from or inserted into the female sleeve 4 of the adapter as the movable plug 11 moves. Likewise, the contact 113 may be separated from or brought into contact with the socket 120 of the socket as the moving pin 11 moves. Slider 111 provides a mounting base for blades 112 and contacts 113 so that blades 112 and contacts can be connected together to electrically connect the receptacle's sleeve 120 to the adapter's sleeve 4.

It will be readily appreciated that the number of blades 112 and contacts 113 should be one-to-one. If the adapter is adapted for a two-hole receptacle, the number of blades 112 and the number of contacts 113 should both be two. If the adapter is adapted for a three-jack receptacle, the number of blades 112 and the number of contacts 113 should each be three (as shown in FIG. 8). That is, the number of blades 112 and contacts 113 may be adjusted according to the applicable socket, which is not limited by this disclosure.

The mating relationship between blades 112 and adapter sleeve 4 is described below in conjunction with fig. 9 and 10. It should be noted that, in order to more clearly show the connection between the blades 112 and the plug sockets 4 of the adapter, the housing 2 is hidden in fig. 9 and 10.

Fig. 9 is a schematic diagram of the position of the plug-in sheet when the adapter is in the power-taking state, when the movable plug 11 extends out relative to the housing 2 and the contact 113 contacts with the plug bush 120 of the socket, the plug-in sheet 112 is also plugged into the plug bush 4 of the adapter, so that the contact 113 and the plug-in sheet 112 can conduct the plug bush 120 of the socket and the plug bush 4 of the adapter, so as to achieve power-taking of the adapter.

Note that, in order to ensure that the insertion piece 112 can be in good contact with the plug bush 4 of the adaptor, the thickness of the insertion piece 112 is slightly larger than the insertion opening of the plug bush 4 of the adaptor. Because the plug bush 4 of adapter is the copper spare, so can have certain toughness, guarantee that the inserted sheet 112 that thickness is great also can smooth and easy grafting to the plug bush 4 of adapter.

Fig. 10 is a schematic diagram illustrating the position of the plug blade when the adapter is in the non-power-supply state, and when the movable pin 11 is retracted relative to the housing 2 and the contact 113 is spaced from the plug bush 120 of the socket, the plug blade 112 is also spaced from the plug bush 4 of the adapter, so that the contact 113 and the plug blade 112 are no longer in conduction with the plug bush 120 of the socket and the plug bush 4 of the adapter, so as to achieve the power-off of the adapter.

Fig. 11 is a schematic view showing the internal structure of the adaptor, and referring to fig. 11, in this embodiment, the housing 2 has a guide groove 22 therein, the guide groove 22 extends along the moving direction of the latch assembly 1, and the slide 111 has a guide table 114 thereon, and the guide table 114 is movably inserted into the guide groove 22.

In the above implementation manner, since the guide groove 22 extends along the moving direction of the plug pin assembly 1, the guide groove 22 can guide the movement of the sliding seat 111, thereby preventing the sliding seat 111 from unnecessarily shaking or tilting during the moving process, and ensuring the reliability of the adapter.

Alternatively, the sliding base 111 is a plate-shaped structural member, the guide table 114 is a long strip-shaped structural member extending from two side edges of the sliding base 111, and the length direction of the guide table 114 is the same as the moving direction of the sliding base 111. Because the two sides of the sliding seat 111 are both provided with the guide platforms 114, the sliding seat 111 can be more stably guided, and the reliability of the adapter is further ensured.

The following describes the manner in which the adapter provided in the practice of the present disclosure is used on a rail receptacle 100:

ensuring that the plug assembly 1 is already in the second position avoids the adapter being energized upon insertion into the track socket 100, eliminating a safety hazard. The plug pin assembly 1 and the catch 23 are inserted into the slide hole 110 from the opening of the end of the rail receptacle 100, thereby completing the installation of the adapter on the rail receptacle 100. In this case, the adapter can freely slide on the rail receptacle 100 along the slide hole 110, thereby moving to a proper position for use by the user.

When the user needs the adapter to get the electricity, move bolt subassembly 1 to the primary importance, the part that bolt subassembly 1 is located the casing 2 outside this moment contacts with the plug bush 120 of socket, has realized getting the electricity of adapter. In addition, under the action of the elastic component 3, the plug pin component 1 can be kept at the first position, so that the plug pin component 1 can be always kept in contact with the plug bush 120 of the socket, namely, the adapter can be stably powered.

When the user does not need the adapter to get the electricity, then move bolt subassembly 1 to the second position, the part that bolt subassembly 1 is located outside casing 2 this moment is with the plug bush 120 interval of socket, has realized the outage of adapter. In addition, the plug pin assembly 1 can be kept at the second position under the action of the elastic assembly 3, so that the interval between the plug pin assembly 1 and the plug bush 120 of the socket can be always kept, namely, the stable power-off of the adapter is realized.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
