For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0043] Please refer to Figures 1 to 6 , Fig.15 and Fig.17 The present embodiment provides a locking mechanism, which includes a movable baffle 10 and an unlocking member 20 connected with the movable baffle 10; the unlocking member 20 has a driving portion 22, and the movable baffle 10 has a first opening 12; when one end of the driving portion 22 extends from the unlocking opening on the outer shell of the wiring module, the unlocking member 20 is locked with the shell 210 of the outer shell so that the movable baffle 10 is locked relative to the shell 210; when the driving portion 22 is driven to retract into the unlocking opening, the movable baffle 10 is unlocked from the shell 210 under the action of the unlocking member 20, and the movable baffle 10 can move relative to the shell 210 so that the copper bar 220 of the wiring module extends out of the first opening 12. The locking mechanism can reliably cover the copper bar 220 after the circuit breaker is pulled out of the wiring base 200.
[0044] The locking mechanism includes a movable baffle 10 and an unlocking member 20, wherein the movable baffle 10 is used to cover or expose the shell 210 of the wiring module, and the unlocking member 20 is used to lock the movable baffle 10 on the shell 210, or unlock the movable baffle 10 relative to the shell 210 so that the movable baffle 10 can move relative to the shell 210.
[0045] It should be noted that the above-mentioned shell 210 is the shell 210 of the wiring base 200 of the wiring module.
[0046] The movable baffle 10 has a first opening 12. Figure 3 and Figure 4As shown, the unlocking opening is used for the driving part 22 of the unlocking member 20 to pass through, and the first opening 12 is used for the copper bar 220 of the wiring module to pass through. It should be noted that when the circuit breaker is not inserted, the copper bar 220 is accommodated in the movable baffle 10 and is hidden by the movable baffle 10; when the circuit breaker is inserted, the circuit breaker can drive the unlocking member 20 to move, so that the unlocking member 20 drives the movable baffle 10 and the housing 210 to unlock relative to each other, and the movable baffle 10 can move to expose the copper bar 220 from the first opening 12 of the movable baffle 10.
[0047] The shape of the unlocking opening should be adapted to the driving part 22 of the unlocking member 20, and the shape of the first opening 12 should be adapted to the shape of the copper bus 220. It should be noted that the unlocking opening is provided on the housing, and the housing includes a shell 210 and a connecting member 70. Figure 1 and Figure 3 As shown, the unlocking opening may be on the connecting member 70 of the housing (ie, the unlocking opening is the second opening 111); or Fig.14 and Fig.15 As shown, the unlocking opening may be on the housing 210 of the shell (ie, the unlocking opening is the third opening 2104 ).
[0048] In this embodiment, when the wiring module is not inserted into the circuit breaker, one end of the driving part 22 can extend from the unlocking opening (the second opening 111 of the movable baffle 10 or the third opening 2104 of the housing 210). At this time, the unlocking member 20 is connected to the movable baffle 10 on one hand and locked with the housing 210 on the other hand. At this time, under the action of the unlocking member 20, the movable baffle 10 cannot move relative to the housing 210, which can avoid the risk of the user accidentally pressing the movable baffle 10 and touching the live copper bus 220;
[0049] When the circuit breaker is inserted into the wiring base 200 of the wiring module, the circuit breaker touches the driving part 22 exposed outside the unlocking opening (the second opening 111 or the third opening 2104), and the driving part 22 retracts into the unlocking opening. The movement of the unlocking member 20 can release the lock between the movable baffle 10 and the shell 210. At this time, the movable baffle 10 can move relative to the shell 210. In this way, the circuit breaker continues to be driven to be inserted into the wiring base 200. Driven by the circuit breaker, the movable baffle 10 moves toward the direction of the copper bus 220, and the copper bus 220 can pass through the first opening 12 and extend out of the first opening 12.
[0050] It should be noted that, in this embodiment, the housing includes a shell 210 and a connector 70. In one implementation, the connector 70 is fixedly connected to the movable baffle 10 and movably connected to the shell 210, that is, the connector 70 is integrally arranged with the movable baffle 10, and the connector 70 is movably connected to the shell 210. In this way, when the circuit breaker is inserted, the connector 70 moves relative to the shell 210 following the movable baffle 10. In this implementation, it is equivalent to integrally arranging the connector 70 with the movable baffle 10. The following mainly takes this method as an example for specific introduction.
[0051] In another implementation, the connector 70 is fixedly connected to the housing 210 and movably connected to the movable baffle 10. In this case, when the circuit breaker is inserted, the movable baffle 10 moves relative to the housing 210, while the connector 70 remains stationary. In this implementation, the connector 70 is equivalent to being integrally arranged with the housing 210.
[0052] Optionally, in the present embodiment, when the housing includes a shell 210 and a connector 70, the unlocking member 20 may be connected to the connector 70; or, the unlocking member 20 may also be connected to the shell 210. When the unlocking member 20 is connected to the connector 70, if the connector 70 is fixedly connected to the movable baffle 10, after the unlocking member 20 unlocks the movable baffle 10 and the shell 210, the movement of the movable baffle 10 toward the copper bus 220 will drive the unlocking member 20 to move synchronously. When the unlocking member 20 is connected to the shell 210, after the unlocking member 20 unlocks the movable baffle 10 and the shell 210, the movable baffle 10 moves toward the copper bus 220, and the unlocking member 20 does not move with the movable baffle 10. The present application does not limit the specific connection position of the unlocking member 20, and those skilled in the art may select a suitable method as needed.
[0053] To summarize, the locking mechanism provided in the present application includes a movable baffle 10 and an unlocking member 20 that is cooperatively connected to the movable baffle 10; the unlocking member 20 has a driving portion 22, and the movable baffle 10 has a first opening 12; when one end of the driving portion 22 extends from the unlocking opening on the outer shell of the wiring module, the unlocking member 20 is locked with the shell 210 of the outer shell so that the movable baffle 10 is locked relative to the shell 210; when the driving portion 22 is driven to retract into the unlocking opening, the movable baffle 10 is unlocked from the shell 210 under the action of the unlocking member 20, and the movable baffle 10 can move relative to the shell 210 so that the copper bus 220 of the wiring module extends out of the first opening 12. The present application sets an unlocking member 20, so that when the circuit breaker is not inserted, the driving part 22 of the unlocking member 20 can extend from the unlocking opening, thereby limiting the movable baffle 10 from moving in the direction close to the copper busbar 220, and preventing the user from accidentally pressing the movable baffle 10 to expose the copper busbar 220 and causing a safety accident; when the circuit breaker is inserted, the circuit breaker can squeeze the driving part 22 to retract the driving part 22 into the unlocking opening, at this time, the unlocking member 20 moves relative to each other, and the movable baffle 10 and the shell 210 can be unlocked under the action of the unlocking member 20. At this time, the movable baffle 10 can move relative to the shell 210, thereby moving toward the direction of the copper busbar 220 driven by the circuit breaker, and then the copper busbar 220 passes through the first opening 12 and extends out of the first opening 12. Through the above configuration, the present application can achieve that the electrical connection between the circuit breaker and the copper busbar 220 is not affected when the circuit breaker needs to be inserted, and the copper busbar 220 can be effectively shielded when the circuit breaker does not need to be inserted, thereby avoiding safety accidents caused by the exposure of the copper busbar 220.
[0054] In a first feasible implementation, optionally, the outer shell includes a shell 210 and a connecting member 70, the connecting member 70 is fixedly connected to the movable baffle 10 and movably connected to the shell 210, the unlocking opening is a second opening 111 arranged on the connecting member 70, and when the driving part 22 is driven to retract into the second opening 111, the unlocking member 20 moves linearly along the central axis direction of the second opening 111.
[0055] That is to say, in this implementation, the driving portion 22 retracts into the second opening 111, and the unlocking member 20 performs a linear motion. Figure 7 , Figure 8 , Figures 10 to 13 shown.
[0056] Please refer to Figures 5 to 8Optionally, the unlocking member 20 includes a first body 21 and a locking portion 23, the driving portion 22 and the locking portion 23 are respectively connected to the first body 21, and the shell 210 is provided with a first matching portion 2101 adapted to the locking portion 23; when one end of the driving portion 22 extends from the second opening 111, the locking portion 23 cooperates with the first matching portion 2101 to lock the unlocking member 20 and the shell 210; when the driving portion 22 retracts into the second opening 111, the locking portion 23 is released from the first matching portion 2101 to unlock the unlocking member 20 and the shell 210.
[0057] The unlocking member 20 includes a first body 21, a locking portion 23 and a driving portion 22. Figure 5 and Figure 6 As shown, the locking portion 23 and the driving portion 22 are respectively provided on the first body 21, and the driving portion 22 is used to extend out of the second opening 111 or be driven to retract into the second opening 111. The locking portion 23 is used to cooperate with the first matching portion 2101 on the housing 210 to lock the movable baffle 10 relative to the housing 210, or to disengage from the first matching portion 2101 on the housing 210 to unlock the movable baffle 10 and the housing 210.
[0058] It should be noted that when the unlocking member 20 retracts into the second opening 111 , the subsequent resetting of the unlocking member 20 can be achieved by its own structure or with the assistance of an elastic member.
[0059] For example, optionally, Figure 7 and Figure 8 , Fig.10 and Fig.11 As shown, the unlocking member 20 may also include a first hook 24 connected to the first body 21, a limiting protrusion 11 is provided on the connecting member 70, a second hook 112 is provided on the limiting protrusion 11, and the first hook 24 and the second hook 112 are hooked; when the driving part 22 retracts into the second opening 111, the first hook 24 stores energy.
[0060] The second opening 111 can be set through the limiting protrusion 11. Figure 7 and Figure 8 As shown; alternatively, the second opening 111 and the limiting protrusion 11 can also be independently provided.
[0061] In this manner, the unlocking member 20 is reset by its own structure. When the driving portion 22 extends from the second opening 111, as shown in FIG. Figure 7 and Figure 8 As shown, the first hook 24 connected to the first body 21 is hooked on the second hook 112, and the first hook 24 is in a natural state (no energy is stored); when the driving part 22 is driven to retract into the second opening 111, as shown in FIG. Fig.10 and Fig.11As shown, at this time, since the first hook 24 and the second hook 112 are in a hooked state, the first hook 24 will deform and store energy; when the drive of the driving part 22 is released, the driving part 22 can be reset under the energy release of the first hook 24 and extend out from the second opening 111.
[0062] For example, optionally, Fig.12 and Fig.13 As shown, the locking mechanism further includes a first return spring 30 having one end connected to the unlocking member 20 and the other end connected to the movable baffle 10 ; the first return spring 30 is used to store energy when the driving portion 22 retracts into the second opening 111 .
[0063] That is to say, in this manner, the reset of the unlocking member 20 is achieved through the auxiliary effect of the elastic member (ie, the first reset spring 30 ).
[0064] When the driving portion 22 extends out from the second opening 111, Figure 7 and Figure 8 As shown, the first return spring 30 is in a natural state (no energy is stored); when the driving part 22 is driven to retract into the second opening 111, the driving part 22 will act on the first return spring 30 to store energy in the first return spring 30; when the driving part 22 is released, the driving part 22 can be reset under the energy release of the first return spring 30 and extend from the second opening 111. In this embodiment, the first return spring 30 is a torsion spring, such as Fig.13 shown.
[0065] In a second possible implementation, optionally, as Fig.14 and Fig.15 As shown, the outer shell includes a shell 210 and a connecting member 70, the connecting member 70 is fixedly connected to the movable baffle 10 and movably connected to the shell 210, the unlocking opening is a third opening 2104 arranged on the shell 210, and when the driving part 22 is driven to retract into the third opening 2104, the unlocking member 20 can be linearly moved relative to the shell 210 along the central axis direction of the third opening 2104.
[0066] When the driving portion 22 is driven to retract toward the third opening 2104, the unlocking member 20 performs a linear motion. Optionally, as shown in FIG. Fig.14 and Fig.15As shown, when the driving portion 22 is driven to retract into the third opening 2104, the unlocking member 20 may further include a second body 25, a first limiting portion 26 and a second limiting portion 27, the driving portion 22, the first limiting portion 26 and the second limiting portion 27 are respectively connected to the second body 25, the housing 210 is provided with a second matching portion 2103 adapted to the first limiting portion 26, and the connecting member 70 is provided with a third matching portion 14 matched with the second limiting portion 27; at one end of the driving portion 22 from the third opening When the driving portion 22 retracts into the third opening 2104, the second limiting portion 27 disengages from the third matching portion 14, and when the movable baffle 10 is driven to move toward the direction close to the copper bus 220, the driving portion 22 disengages from the third opening 2104 to unlock the unlocking member 20 and the movable baffle 10.
[0067] It should be noted that the unlocking member 20 includes a second body 25, a driving portion 22 connected to the second body 25, a first limiting portion 26 connected to the second body 25, and a second limiting portion 27 connected to the second body 25. The housing 210 is provided with a second matching portion 2103 corresponding to the first limiting portion 26, and the connecting member 70 is provided with a third matching portion 14 corresponding to the second limiting portion 27.
[0068] When one end of the driving portion 22 extends out from the third opening 2104, Fig.15 As shown, the first limiting portion 26 is located in the second matching portion 2103, the second limiting portion 27 cooperates with the third matching portion 14, and the unlocking member 20 locks the movable baffle 10 and the shell 210; when the driving portion 22 is driven to retract into the third opening 2104, the first limiting portion 26 continues to move toward the second matching portion 2103, and the second limiting portion 27 disengages from the third matching portion 14. When the movable baffle 10 is driven to move in a direction close to the copper bus 220, the driving portion 22 disengages from the third opening 2104 to unlock the unlocking member 20 and the movable baffle 10.
[0069] It should be noted that the driving portion 22 may be provided with a guide surface 221 on a side facing away from the second matching portion 2103. Fig.15 As shown, when the movable baffle 10 is driven to move toward the copper bus 220 , the movable baffle 10 can act on the guide surface 221 of the driving part 22 to drive the driving part 22 to disengage from the third opening 2104 , thereby unlocking the unlocking member 20 and the movable baffle 10 .
[0070] In order to enable the unlocking member 20 to be quickly reset, in this mode, the locking mechanism may further include a fourth reset spring 60, one end of which is connected to the unlocking member 20 and the other end of which is connected to the housing 210; the fourth reset spring 60 is used to store energy when the driving portion 22 is retracted into the third opening 2104. The fourth reset spring 60 can be provided so that when the driving portion 22 is released, the unlocking member 20 can be quickly reset under the energy release of the fourth reset spring 60, and the driving portion 22 of the unlocking member 20 extends from the third opening 2104.
[0071] In a third possible implementation, optionally, as Fig.16 and Fig.17 As shown, the outer shell includes a shell 210 and a connecting member 70, the connecting member 70 is fixedly connected to the movable baffle 10 and movably connected to the shell 210, the unlocking opening is a third opening 2104 arranged on the shell 210, and when the driving part 22 is driven to retract into the third opening 2104, the unlocking member 20 can also rotate relative to the shell 210.
[0072] That is, in this implementation, the driving portion 22 retracts into the third opening 2104, the circuit breaker drives the driving portion 22 to move, and the unlocking member 20 rotates relative to the housing 210. Fig.16 and Fig.17 shown.
[0073] In this implementation, optionally, Fig.16 and Fig.17 As shown, when the driving portion 22 is driven to retract into the third opening 2104, the unlocking member 20 includes a third body 28 and a third limiting portion 29, and the third limiting portion 29 and the driving portion 22 are respectively connected to the third body 28; a fourth matching portion 15 for matching with the third limiting portion 29 is provided on the connecting member 70; the locking mechanism also includes a second return spring 40 connected to the third body 28 at one end and connected to the shell 210 at the other end; when the driving portion 22 retracts into the third opening 2104, the unlocking member 20 rotates relative to the shell 210 to unlock the third limiting portion 29 and the fourth matching portion 15, and the second return spring 40 stores energy.
[0074] It should be noted that the third body 28 can be rotatably connected to the shell 210. When the driving part 22 extends out of the third opening 2104, the third limiting part 29 cooperates with the fourth matching part 15 on the connecting member 70, so that the movable baffle 10 and the shell 210 are locked by the unlocking member 20. At this time, the second return spring 40 is in a natural state; when the driving part 22 is driven to retract into the third opening 2104, the unlocking member 20 rotates relative to the shell 210 to disengage the third limiting part 29 from the fourth matching part 15 and unlock. At this time, the movable baffle 10 can move relative to the shell 210. At this time, the second return spring 40 is compressed to store energy; after the driving part 22 is released from being driven, under the energy release action of the second return spring 40, the driving part 22 passes through the third opening 2104 and extends out of the third opening 2104, and the third limiting part 29 continues to be clamped at the fourth matching part 15.
[0075] Similarly, the driving portion 22 may also be provided with a guide surface 221 on a side facing away from the third body 28. Fig.17 As shown, when the driving portion 22 retracts into the third opening 2104 and the movable baffle 10 is driven to move toward the direction close to the copper bus 220, the movable baffle 10 can act on the guide surface 221 of the driving portion 22 to drive the driving portion 22 to disengage from the third opening 2104, thereby unlocking the unlocking member 20 and the movable baffle 10.
[0076] In addition, it should be noted that the multiple matching parts mentioned above can be groove structures, and correspondingly, the locking part 23 and the limiting part etc. that match the corresponding groove structures can be convex structures. Alternatively, the groove structure and the convex structure can also be interchangeable.
[0077] Please refer to Fig. 9 Optionally, a sliding groove is provided on the locking mechanism, and a guide bar 2102 adapted to the sliding groove is convexly provided on the shell 210, and the extension direction of the guide bar 2102 is parallel to the length direction a of the copper busbar; when the driving part 22 retracts into the unlocking opening (the second opening 111 or the third opening 2104), the sliding groove is driven to slide along the extension direction of the guide bar 2102.
[0078] The sliding groove on the locking mechanism can be provided only on the connecting member 70, or can be formed by the connecting member 70 and the unlocking member 20. The guide bar 2102 is provided on the housing 210, and the setting of the guide bar 2102 and the sliding groove can guide the movement of the movable baffle 10 relative to the housing 210, so that the movement of the movable baffle 10 is more reliable.
[0079] In order to further improve the sliding reliability of the movable baffle 10, optionally, please refer to Figures 2 to 4The movable baffle 10 is provided with a third hook 13 on one side close to the guide bar 2102. When the driving part 22 is retracted into the unlocking opening (the second opening 111 or the third opening 2104), the third hook 13 overlaps the guide bar 2102. In this way, the third hook 13 and the sliding groove can play a dual guiding role.
[0080] To facilitate the driving of the driving part 22, especially to facilitate the driving of the driving part 22 by the circuit breaker when the circuit breaker is inserted into the wiring base 200 of the wiring module, the driving part 22 can be optionally provided with a first guide surface 221, and the first guide surface 221 is arranged at an acute angle to the central axis of the unlocking opening (the second opening 111 or the third opening 2104), such as Figure 1 and Figure 2 The arrangement of the guide surface 221 enables the driving portion 22 to retract quickly.
[0081] Optionally, see Figure 2 As shown, the locking mechanism also includes a third return spring 50, one end of the third return spring 50 is connected to the housing 210, and the other end is connected to the movable baffle 10, and the third return spring 50 is used to provide the movable baffle 10 with a movement tendency in a direction away from the copper bus 220.
[0082] When the driving portion 22 extends from the unlocking opening (the second opening 111 or the third opening 2104), the third return spring 50 is in a natural state; when the movable baffle 10 moves toward the copper bar 220, the third return spring 50 stores energy; when the drive to the movable baffle 10 is released, the movable baffle 10 can be reset under the action of the third return spring 50. The present application can quickly reset the movable baffle 10 by providing the third return spring 50.

[0084] Among them, the specific structure and technical effects of the above-mentioned locking mechanism have been described and explained in detail in the previous text and will not be repeated here.
[0085] In the wiring module of the present application, when the circuit breaker is not inserted into the wiring base 200, the driving part 22 of the locking mechanism extends from the unlocking opening (the second opening 111 or the third opening 2104), and the movable baffle 10 is locked relative to the shell 210 and cannot move, which can avoid the safety accident caused by the movable baffle 10 accidentally touching and exposing the copper bus 220; when the circuit breaker is inserted into the wiring base 200, the circuit breaker acts on the driving part 22 of the locking mechanism, and the driving part 22 retracts into the unlocking opening (the second opening 111 or the third opening 2104), and the unlocking member 20 unlocks the shell 210 and the movable baffle 10, and the movable baffle 10 can move toward the copper bus 220 under the drive of the circuit breaker, and at this time, the copper bus 220 can be exposed from the first opening 12 on the movable baffle 10, so as to be electrically connected to the circuit breaker.
