Description

Technical Field

[0001] This disclosure relates to the field of socket technology, and more specifically to an adapter and a track socket. Background Technology

[0002] A track socket is a portable socket consisting of a track and an adapter, which can be fitted at different locations on the track to draw power.

[0003] A related technology provides an adapter comprising a fixed socket body and a power-receiving body. The socket body is used to mate a plug, and the power-receiving body extends into the interior of a track to draw power. The power-receiving body includes a power-receiving housing and contact pieces. The contact pieces have contacts that protrude from the sidewall of the power-receiving housing. When the adapter is assembled in the track, the contacts contact conductive plates in the track to draw power from the track.

[0004] However, because the contacts protrude from the power-receiving housing, they are easily worn, which undoubtedly reduces the reliability and lifespan of the adapter. Summary of the Invention

[0102] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0103] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0104] This disclosure provides an adapter, such as... Figure 1 and Figure 2 As shown, the adapter includes a socket body 1 and a power-receiving body 2, with the socket body 1 and the power-receiving body 2 fixedly connected. The socket body 1 includes a socket housing 11 and a socket assembly 12, with the socket assembly 12 located inside the socket housing 11. The power-receiving body 2 includes a power-receiving housing 21, a contact assembly 22, and a driving member 23. The contact assembly 22 is electrically connected to the socket assembly 12, with one side of the contact assembly 22 having a contact 220, and the side wall of the power-receiving housing 21 having an opening 210 corresponding to the contact 220. The driving member 23 is movably connected to the power-receiving housing 21, and the driving member 23 is configured to control the contact 220 to extend or retract through the opening 210 into the power-receiving housing 21.

[0105] The socket body 1 is used for accommodating a plug. The socket body 1 includes a socket housing 11 and a socket sleeve assembly 12. The portion of the socket housing 11 corresponding to the socket sleeve assembly 12 has a socket hole for inserting the plug. In addition, the socket body 1 may also include a protective door assembly, which is located inside the socket housing 11 and covers the socket hole.

[0106] The power-receiving element 2 is used to extend into the interior of the track to draw power. The power-receiving element 2 is fixedly connected to the socket body 1, as in some examples, such as... Figure 1 As shown, the power take-up element 2 is fixedly connected to the side of the socket body 1 facing away from the socket, and there is a gap between the power take-up element 2 and the socket body 1 for accommodating the sidewall of the track. In other examples, the power take-up element 2 may also be fixedly connected to the sidewall of the socket body 1, which is perpendicular to the shell wall where the socket is located. The power take-up element 2 may also be referred to as a plug or a hanger, etc.

[0107] The contact assembly 22 has contacts 220 for contacting conductive plates in the track to draw power from the track. The contact assembly 22 may include two contacts 221 (L-pole contact and N-pole contact), or three contacts 221 (L-pole contact, N-pole contact, and E-pole contact). Each contact 221 may have one contact 220 on one side. In some examples, such as... Figure 1 As shown, the heights of the multiple contacts 220 are different along the insertion direction of the power-taking body 2. Of course, the heights of the multiple contacts 220 can also be the same, and this embodiment does not limit this.

[0108] The driving element 23 is used to control the contact 220 to extend or retract through the opening 210 into the power receiving housing 21. There are various ways to implement the driving element 23, and this embodiment does not limit it.

[0109] The technical solution shown in this embodiment allows the contact 220 to extend from the power-receiving housing 21 via the drive unit 23 when the adapter is in a power-receiving state, making contact with the conductive sheet in the track. When the adapter is in a power-off state, such as when it is pulled out of the track, the contact 220 can be retracted from the power-receiving housing 21 via the drive unit 23, reducing the possibility of wear on the contact 220 and thus improving the reliability and service life of the adapter.

[0110] The following is an exemplary description of the driver 23:

[0111] like Figure 3 As shown, the drive member 23 is located on the side of the contact assembly 22 opposite to the contact 220. The drive member 23 is configured to push the contact assembly 22 so that the contact 220 extends out of the power receiving housing 21 through the opening 210.

[0112] When the driving component 23 does not push the contact assembly 22, the contact assembly 22 can drive the contact 220 to spring back through the opening 210 into the power-taking housing 21 under its own elastic drive.

[0113] In some examples, the drive member 23 is slidably connected to the power-collecting housing 21 along the insertion / removal direction of the power-collecting body 2. The drive member 23 has a protrusion facing the contact assembly 22. When the drive member 23 slides along the removal direction, the protrusion contacts the contact assembly 22 and pushes the contact 220 gradually out of the power-collecting housing 21. When the drive member 23 slides along the insertion direction, the protrusion gradually separates from the contact assembly 22, and the contact 220 gradually springs back into the power-collecting housing 21.

[0114] In some examples, the portion of the actuator 23 used to push the contact assembly 22 is elastic. Furthermore, when there is no external obstruction to the contact 220, the actuator 23 can push the contact 220 out of the power-collecting housing 21 by a maximum length L1, while when the actuator 23 pushes the contact 220 to contact the conductive sheet in the track, the length of the contact 220 extending out of the power-collecting housing 21 is L2, where L1 is greater than L2.

[0115] In this way, the drive unit 23 can compensate for the travel of the contact 220, and the maximum compensated travel is equal to the difference between L1 and L2. When the length of the contact 220 decreases due to wear, the drive unit 23 can push the contact 220 to continue to extend, so that when the contact 220 contacts the conductive sheet in the track, the extension length L2 of the contact 220 will not decrease due to wear. The contact 220 and the conductive sheet in the track can always be in close contact, resulting in high reliability.

[0116] Of course, the part of the driving component 23 used to push the contact assembly 22 may not be elastic, and this disclosure does not limit this.

[0117] The structure of the driver 23 will be illustrated below with a specific example:

[0118] like Figure 4 and Figure 5 As shown, the driving member 23 includes a support member 231 and a spring piece 232. The support member 231 is slidably connected to the power-collecting housing 21 along the insertion direction of the power-collecting body 2. A portion of the spring piece 232 is fixedly connected to the support member 1, and another portion of the spring piece 232 extends along the insertion direction of the power-collecting body 2 and has a protrusion 2321 protruding toward the contact assembly 22. The protrusion 2321 is used to push the contact assembly 22.

[0119] The support component 231 can be made of plastic. The spring 232 is elastic and can be made of metal.

[0120] The technical solution provided in this embodiment uses an elastic spring 232 to push the contact assembly 22, so that the driving member 23 can compensate the stroke of the contact 220, which can make the contact 220 make close contact with the conductive sheet in the track and improve reliability.

[0121] This disclosure does not limit the location or formation of the protrusion 2321. In some examples, such as Figure 4 and Figure 5As shown, the protrusion 2321 is formed by the end of the spring 232 that is raised away from the support 231. In other examples, the protrusion 2321 may also be formed by bending the middle portion of the spring 232. In other examples, the protrusion 2321 may be formed by attaching or welding a protrusion to the side of the body of the spring 232 facing the contact assembly 22, for example, by attaching a plastic block (the elasticity is provided by the spring 232) to the side of the spring 232 facing the contact assembly 22.

[0122] Furthermore, when the contact assembly 22 includes multiple contacts 221, there are also multiple springs 232. Moreover, the multiple springs 232 should be able to simultaneously push multiple contacts 220 out of the power-collecting housing 21. Therefore, when the multiple contacts 220 are at different heights along the insertion / removal direction of the power-collecting body 2, the protrusions 2321 of the multiple springs 232 are also at different heights, and the positions of the multiple protrusions 2321 correspond one-to-one with the positions of the multiple contacts 220.

[0123] The specific form of the support member 231 will be described below by way of example:

[0124] like Figure 4 and Figure 5 As shown, the support member 231 includes a plate portion 2311 and an operating portion 2312. The plate portion 2311 is fixedly connected to the spring piece 232 and is slidably connected to the power-collecting housing 21. The operating portion 2312 is fixedly connected to the plate portion 2311, protrudes relative to the plate portion 2311, and is exposed on the outside of the power-collecting housing 21. The operating portion 2312 may be a boss located on the plate portion 2311.

[0125] The embodiments disclosed herein do not limit the exposed position of the operation unit 2312 in the power-taking housing 21.

[0126] In some examples, such as Figure 5 and Figure 6 As shown, the operating part 2312 is located on the side of the plate part 2311 away from the contact assembly 22, and is exposed on the first side wall 211 of the power receiving housing 21. The first side wall 211 is opposite to the side wall where the opening 210 is located (i.e., the second side wall 212). During the insertion of the power receiving body 2 into the track, the track wall on the opening side of the track pushes the operating part 2312 to slide, thereby driving the driving member 23 to push the contact assembly 22.

[0127] There can be two operating parts 2312, and the two operating parts 2312 are flush, so that the track wall can push the two operating parts 2312 at the same time, making the sliding of the drive member 23 smoother.

[0128] By exposing the operating part 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 simultaneously, making the operation simple and convenient for the user.

[0129] In addition, such as Figure 6 As shown, by exposing the operating part 2312 in the gap between the socket body 1 and the power receiving body 2, it is difficult for the user to touch the operating part 2312 when the adapter is unplugged from the rail, thereby reducing the possibility that the contact 220 will protrude from the power receiving housing 21 due to accidental touch by the user.

[0130] Of course, the operating part 2312 may also be exposed on the other side wall of the power receiving housing 21, and this embodiment of the present disclosure does not limit this.

[0131] In some examples, the operating part 2312 may also be located on the side of the plate part 2311 near the contact assembly 22, and on the second sidewall 212 of the power receiving housing 21 (e.g. Figure 6 As shown, the second sidewall 212 (the sidewall where the opening 210 is located) is exposed. During the process of inserting the power take-off body 2 into the track, the track wall on the side of the opening of the track will also push the operating part 2312 to slide, so as to drive the driving member 23 to push the contact assembly 22.

[0132] In addition, the insertion of the adapter and the extension of the contact 220 out of the power-collecting housing 21 can be performed at different times. In some other examples, the operating part 2312 is exposed on the third or fourth side wall of the power-collecting housing 21 (both the third and fourth side walls are perpendicular to the first side wall 211). In this case, after the user inserts the adapter into the track, he drives the driving member 23 to push the contact assembly 22 by moving the operating part 2312, so that the contact 220 extends out of the power-collecting housing 21.

[0133] To ensure that when the adapter is not subjected to external force, the contact 220 can automatically spring back into the power-taking housing 21 and remain stably inside the power-taking housing 21, in some examples, such as... Figure 7 As shown, the support member 231 further includes a spring mounting portion 2313, and the drive member 23 further includes a return spring 233. One end of the return spring 233 near the protrusion 2321 contacts the spring mounting portion 2313, and the other end of the return spring 233 away from the protrusion 2321 contacts the inner wall of the power-collecting housing 21, and the return spring 233 is in a compressed state. The return spring 233 is configured to push the support member 231 to slide, thereby separating the protrusion 2321 from the contact assembly 22.

[0134] The axis of the return spring 233 can be parallel to the sliding direction of the support member 231. The return spring 233 is located on the side of the support member 231 away from the protrusion 2321.

[0135] The technical solution provided in this embodiment, by setting a reset spring 233, allows the support member 231 to slide automatically when the adapter is pulled out of the track, causing the protrusion 2321 to separate from the contact assembly 22, thereby causing the contact 220 to automatically retract into the power-taking housing 21. This eliminates the need for additional user intervention and is very convenient.

[0136] The embodiments disclosed herein do not limit the number of spring mounting portions 2313 and return springs 233. For example, such as... Figure 7 As shown, there are two spring mounting portions 2313 and two return springs 233, with the two spring mounting portions 2313 located on both sides of the plate portion 2311, and the two return springs 233 abutting against the two spring mounting portions 2313 respectively. Therefore, the force on the support member 231 is more even, and the sliding of the support member 231 is smoother.

[0137] The embodiments disclosed herein do not limit the shape of the spring mounting portion 2313; for example, such as Figure 8 As shown, the spring mounting part 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 surface of the spring mounting plate 23131 and extends into the interior of the return spring 233.

[0138] To make the contact 220 more stable when it extends out of the power-taking housing 21, such as Figure 9 and Figure 10 As shown, the plate body 2311 has a locking hole 23111 on its surface, and the adapter also includes a locking member 24. The locking hole 23111 can be a through hole or a blind hole; this embodiment does not limit the type of hole.

[0139] The locking member 24 is configured to extend into the locking hole 23111 when the contact 220 extends out of the power-receiving housing 21 through the opening 210. Thus, the locking member 24 can lock the drive member 23, so that the contact 220 can be stably kept in the state of extending out of the power-receiving housing 21.

[0140] This disclosure does not limit the implementation of the locking member 24. Below, a possible implementation is provided:

[0141] like Figure 11As shown, the locking member 24 includes a locking rod 241, a locking spring 242, and an unlocking member 243. The locking rod 241 is slidably connected to the inner wall of the power supply housing 21, and the sliding direction of the locking rod 241 intersects the sliding direction of the plate portion 2311. The locking rod 241 is used to extend into the interior of the locking hole 23111. The end of the locking spring 242 near the plate portion 2311 abuts against the locking rod 241, and the end of the locking spring 242 away from the plate portion 2311 abuts against the inner wall of the power supply housing 21. 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 protrudes from the outside of the socket housing 11. The unlocking member 243 can drive the locking rod 241 to slide away from the plate portion 2311.

[0142] The sliding direction of the locking rod 241 can be perpendicular to the sliding direction of the plate part 2311.

[0143] The axis of the locking spring 242 is parallel to the sliding direction of the locking rod 241. The function of the locking spring 242 is to push the locking rod 241 out so that the locking rod 241 can be stably inserted into the locking hole 23111.

[0144] The unlocking component 243 is used to drive the locking rod 241 to retract from the locking hole 23111, thereby releasing the locking state of the driving component 23 and allowing the contact 220 to smoothly spring back into the power-taking housing 21.

[0145] The working principle of locking element 24 is as follows:

[0146] When contact 220 extends out of power-receiving housing 21, under the pushing force of locking spring 242, locking rod 241 extends into locking hole 23111. Drive member 23 is locked, and contact 220 is stabilized in the state of extending out of power-receiving housing 21.

[0147] When it is necessary to release the locking state of the drive component 23, the unlocking component 243 is pushed to overcome the elastic force of the locking spring 242, causing the locking rod 241 to retract from the locking hole 23111. Then the drive component 23 is unlocked, and the contact 220 can smoothly retract into the power-taking housing 21.

[0148] In order to automatically complete the locking action of the drive element 23 while the control contact 220 extends out of the power-taking housing 21, in some examples, such as Figure 12As shown, the side wall of the plate portion 2311 that contacts the locking rod 241 has a first guide slope 23112. The first guide slope 23112 is inclined relative to the sliding direction of the plate portion 2311 and faces the locking rod 241. The end of the locking rod 241 near the plate portion 2311 has a second guide slope 2410. The second guide slope 2410 is inclined relative to the sliding direction of the locking rod 241 and faces the first guide slope 23112. The first guide slope 23112 is configured to push the locking rod 241 back through the second guide slope 2410.

[0149] During the process of the driving member 23 pushing the contact 220 out of the power-collecting housing 21, the first guide slope 23112 of the plate portion 2311 contacts the second guide slope 2410, and the plate portion 2311 pushes the locking rod 241 to gradually retract against the elastic force of the locking spring 242. At the same time, the plate portion 2311 continues to move upward. When the locking rod 241 is aligned with the locking hole 23111, the locking rod 241 is no longer obstructed, and under the elastic force of the locking spring 242, the locking rod 241 extends into the interior of the locking hole 23111, and the driving member 23 is locked. At the same time, the action of the driving member 23 pushing the contact 220 out of the power-collecting housing 21 is also completed simultaneously.

[0150] like Figure 13 The image shown is an exploded view of a locking member 24 provided in an embodiment of this disclosure. The locking member 24 includes a locking rod 241, a locking spring 242, and an unlocking member 243.

[0151] The locking lever 241 includes a locking lever body 2411 and a first connecting portion 2412. The locking lever body 2411 has an opening 24111, and the opening 24111 has a mounting post 24112 near the inner wall of the driving member 23. The inner wall of the power supply housing 21 may have a baffle 213 (e.g., Figure 11 As shown, the baffle 213 can be located on the side of the opening 24111 away from the drive member 23. The locking spring 242 can be located in the opening 24111, with one end looped around the mounting post 24112 and the other end abutting against the baffle 213. The first connecting part 2412 has a snap-fit ​​hole.

[0152] The unlocking component 243 includes a push button 2431 and a second connecting part 2432. One end of the second connecting part 2432 is connected to the push button 2431, and the other end has a latch. The latch of the second connecting part 2432 engages with the latching hole of the first connecting part 2412. The push button 2431 is exposed on the outside of the socket housing 11 for the user to push.

[0153] The following is an illustrative description of the entire working process of the adapter, based on the above content:

[0154] During the insertion of the adapter into the track, the track wall on the open side of the track pushes the operating part 2312, causing the entire drive member 23 to slide. During the sliding of the drive member 23, the protrusion 2321 of the spring 232 pushes the contact assembly 22, causing the contact 220 to gradually protrude from the opening 210.

[0155] As the protrusion 2321 pushes the contact assembly 22, the plate 2311 pushes the locking rod 241 back until the locking rod 241 aligns with the locking hole 23111 on the plate 2311. Then, under the thrust of the locking spring 242, the locking rod 241 extends into the locking hole 23111, locking the position of the drive member 23. Furthermore, at this position, the contact 220 extends out of the power-collecting housing 21 and contacts the conductive sheet in the track. At this time, because the contact 220 extends out of the power-collecting housing 21, the adapter is not easily pulled out.

[0156] When you want to disconnect the adapter from power, push the unlocking member 243 to retract the locking lever 241 from the locking hole 23111, and the driving member 23 will release the lock. Under the pushing force of the return spring 233, the support member 231 drives the protrusion 2321 of the spring piece 232 to move away from the contact assembly 22, and the contact 220 gradually retracts into the power-taking housing 21, disconnecting the adapter from power. At this time, the adapter can be pushed to slide or pulled out of the track.

[0157] The embodiments disclosed herein do not limit the implementation of the electrical connection between the socket assembly 12 and the contact assembly 22. In some examples, the socket assembly 12 may be soldered to the contact assembly 22, while in other examples, the socket assembly 12 may be connected to the contact assembly 22 via jumpers.

[0158] The following example illustrates the structure of the socket assembly 12 and the contact assembly 22 by taking the welding of the socket assembly 12 and the contact assembly 22 as an example:

[0159] like Figure 14 As shown, the socket assembly 12 includes a plurality of sockets 121, each socket 121 including a socket body 1211 and a connecting piece 1212, the first end of the connecting piece 1212 being connected to the socket body 1211. The contact assembly 22 includes a plurality of contacts 221, one side of which has a contact point 220. The second ends of the connecting pieces 1212 of the plurality of sockets 121 are respectively welded to the ends of the plurality of contacts 221 away from the contact point 220.

[0160] The solution shown in this embodiment of the present disclosure makes the electrical connection between the socket assembly 12 and the contact assembly 22 more stable by welding the plurality of sockets 121 in the socket assembly 12 to the plurality of contacts 221 in the contact assembly 22.

[0161] To improve welding stability, in some examples, such as Figure 15 As shown, the second end of the connecting piece 1212 has a welding hole 12120, and the end of the contact piece 221 away from the contact point 220 has a lifting piece 22140, which extends into and is welded into the welding hole 12120.

[0162] Of course, in other examples, the second end of the connecting piece 1212 may have a tab, while the end of the contact piece 221 away from the contact point 220 may have a weld hole, into which the tab extends and is welded.

[0163] The specific form of the sleeve 121 is not limited in the embodiments disclosed herein. In some examples, the sleeve 121 can be integrally bent. During the manufacturing process of the sleeve 121, a strip-shaped bent piece is first stamped on a metal sheet, and then the bent piece is bent to obtain the sleeve 121.

[0164] Compared with conventional sockets, the socket 121 provided in this embodiment of the present disclosure adds a connecting piece 1212. The addition of the connecting piece 1212 inevitably leads to an increase in the material used in the socket 121. However, through reasonable structural design, the socket 121 provided in this embodiment of the present disclosure can reduce the material used in the socket 121 by a small amount, thereby improving the material utilization rate.

[0165] The following description uses examples of socket 121 as an L-type socket, N-type socket, and E-type socket to illustrate the specific form of socket 121:

[0166] like Figure 16 As shown, the socket 121 is either an L-pole socket or an N-pole socket. The socket body 1211 includes a first main current-carrying plate 12111 and two first clamping plate pairs 12112, which are connected to one side of the first main current-carrying plate 12111. The connecting piece 1212 includes a connected first connecting section 12121 and a connected second connecting section 12122.

[0167] The first connecting segment 12121 and the first clamping plate pair 12112 are located on the same side of the first main current carrier plate 12111. The first connecting segment 12121 is located between the two first clamping plate pairs 12112 and is bent away from the E-pole socket relative to the first main current carrier plate 12111.

[0168] The second connecting segment 12122 is located on the same side of the first connecting segment 12121 as one of the first clamping plate pairs 12112, and on a different side of the first connecting segment 12121 as another of the first clamping plate pairs 12112. The first connecting segment 12121 and the second connecting segment 12122 may be located in the same plane and perpendicular to each other. Furthermore, the second connecting segment 12122 is retracted relative to the first main flow carrier 12111 in its deployed state. The second connecting segment 12122 may have weld holes 12120.

[0169] like Figure 17 The diagram shows the material layout for the L-pole or N-pole socket with the above structure. As can be seen from the layout diagram, the addition of the connecting piece 1212 does not significantly increase the material usage of the socket 121, and the material utilization rate of the socket 121 is very high.

[0170] Specifically, since the connecting piece 1212 is located between the two first clamping pieces 12112 and is shorter than the sleeve body 1211 in the length direction, the addition of the connecting piece 1212 does not increase the material used in the length direction.

[0171] Since the connecting piece 1212 and the first clamping piece pair 12122 are located on the same side of the first main current carrier piece 12111, there is no excessive increase in material usage in the width direction.

[0172] like Figure 18 As shown, the socket 121 is an E-pole socket. The socket body 1211 includes a second main current carrier plate 12113 and a second clamping plate pair 12114, the second clamping plate pair 12114 being connected to one side of the second main current carrier plate 12113. The connecting piece 1212 includes a connected third connecting segment 12123, a fourth connecting segment 12124, and a fifth connecting segment 12125. The third connecting segment 12123 and the second clamping plate pair 12114 are located on the same side of the second main current carrier plate 12113. The fourth connecting segment 12124 is located on the side of the third connecting segment 12123 away from the second clamping plate pair 12114. The fifth connecting segment 12125 is located on the side of the fourth connecting segment 12124 away from the second main current carrier plate 12113.

[0173] like Figure 19 The diagram shows the material layout for the E-pole socket of the above structure. As can be seen from the layout, the addition of the connecting piece 1212 did not significantly increase the material usage of the socket 121, and the material utilization rate of the socket 121 is very high.

[0174] Specifically, since the connecting piece 1212 and the second clamping piece pair 12114 are located on the same side of the second main current carrier piece 12113, there is no excessive increase in material usage in the width direction.

[0175] Furthermore, the fourth connecting segment 12124 is located on the side of the third connecting segment 12123 away from the second clamping plate pair 12114, and the fifth connecting segment 12125 is located on the side of the fourth connecting segment 12124 away from the second main carrier plate 12113, as shown below. Figure 19 As shown, this design ensures that the material used for the E-pole socket does not increase excessively in the length direction. Furthermore, in the material layouts corresponding to two adjacent E-pole sockets, the fifth connecting segment 12125 of one E-pole socket can extend into the notch c of the other E-pole socket, further reducing the material used for the E-pole socket in the width direction.

[0176] In some examples, the fifth connecting segment 12125 is bent relative to the fourth connecting segment 12124 and is perpendicular to each other. The fifth connecting segment 12125 may have a weld hole 12120.

[0177] To make the contact assembly 22 more stable inside the power-taking housing 21, such as Figure 20 As shown, the contact assembly 22 also includes a rubber-coated plate 222. The rubber-coated plate 222 fixes the multiple contacts 221 together, and the rubber-coated plate 222 is fixedly connected to the power-collecting housing 21.

[0178] Contact 220 is not covered by the rubber-coated plate 222.

[0179] This disclosure does not limit the position of the contact piece 221 covered by the rubber sheet 222. In some examples, the end of the contact piece 221 away from the contact 220 should be exposed for welding to the socket assembly 12. In addition, the section containing the contact 220 should be exposed so that the contact 220 is suspended inside the power receiving housing 21, thereby making the contact 220 easier to be pushed by the drive member 23.

[0180] For example, such as Figure 21 As shown, the contact piece 221 includes a suspended section 2211, a first fixed section 2212, a second fixed section 2213, and a connecting section 2214 connected in sequence. The end of the suspended section 2211 away from the first fixed section 2212 has a contact point 220. The second fixed section 2213 is bent relative to the first fixed section 2212 toward the socket assembly 12. The connecting section 2214 is welded to the contact piece 221.

[0181] The rubber-coated plate 222 covers the first fixed section 2212 and the second fixed section 2213, and the suspended section 2211 is suspended inside the power-collecting housing 21, so that the suspended section 2211 is more easily pushed by the driving member 23.

[0182] The first fixed section 2212 can be parallel to the insertion and removal direction of the power-taking body 2, and the second fixed section 2213 can be perpendicular to the first fixed section 2212.

[0183] This disclosure also provides a track socket, such as Figure 22 As shown, the track socket includes track a and adapter b.

[0184] When adapter b is in the power-drawing state, the contacts 220 of adapter b extend out of the power-drawing housing 21 and come into contact with the conductive sheet in track a.

[0185] When adapter b is in the power-off state, the contacts 220 of adapter b retract into the power-receiving housing 21 and separate from the conductive sheet in track a.
