Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a terminal block assembly and a circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can cut off and connect load circuits, as well as cut off fault circuits to ensure safe operation. It is one of the important distribution electrical appliances in low-voltage power grid systems.

[0003] When multiple circuit breakers are to be connected to distribute the total current to multiple power circuits, they can be connected via a busbar. A busbar interface is usually provided in the circuit breaker for plugging the busbar to connect multiple circuit breakers.

[0004] However, this connection method is only applicable to the connection between the circuit breaker and a busbar of a specific specification and has poor versatility. Utility Model Content

[0005] The present application provides a terminal block assembly and a circuit breaker, which can adapt to the connection of buses of different specifications and improve versatility.

[0006] In a first aspect, the present application provides an operating handle mechanism, comprising a housing, a terminal and an elastic member. The housing has a receiving cavity inside, and a cavity wall of the receiving cavity is provided with a socket, which is connected to the outside of the housing. The terminal is slidably arranged in the receiving cavity, part of the terminal is opposite to the socket, and there is a wiring space inside the terminal. The elastic member has a first end and a second end opposite to each other, the first end abuts against the cavity wall of the receiving cavity, and the second end abuts against the terminal.

[0007] The socket is used to plug the bus. During the plugging process of the bus, the bus pushes the elastic member through the terminal so that different parts of the wiring space are opposite to the socket. The bus extends into the wiring space through the socket and abuts against the terminal.

[0008] In the terminal assembly provided in the embodiment of the present application, the busbar can push the terminal to change the position of the terminal and the socket, so that the wiring space can be opposite to the socket. In this way, part of the wiring space opposite to the socket can be exposed to facilitate the insertion of the busbar.

[0009] For buses of different specifications, the sliding distance of the rear terminal after the bus pushes against the terminal is different, which can make the compression degree of the elastic member different. In this way, the relative parts of the terminal and the socket are also different, which can adapt to the plugging of buses of different specifications and improve the versatility of the terminal assembly.

[0010] Optionally, the terminal assembly further includes an adjusting pad, which is arranged on a side of the terminal away from the elastic member, and an end of the adjusting pad away from the terminal abuts against the housing.

[0011] When the socket is not connected to the busbar, one end of the adjusting pad facing the terminal abuts against the terminal, and the adjusting pad presses the elastic member through the terminal to put the elastic member in a compressed state.

[0012] Through the above arrangement, the two ends of the terminal are respectively connected to the adjusting pad and the elastic member. The adjusting pad is located on the side of the terminal away from the elastic member, so the adjusting pad and the elastic member can support the terminal on both sides of the terminal.

[0013] Optionally, a mounting plate is provided on the housing, and the mounting plate is located on a side of the terminal facing away from the elastic member.

[0014] The adjusting pad includes a limit part and a support part connected to each other, and the limit part and the support part are distributed along the sliding direction of the terminal. The limit part is embedded in the mounting plate, and the support part extends outward from the mounting plate. The support part is used to abut against the terminal when the socket is not plugged with a busbar.

[0015] By arranging the mounting plate in the housing, a mounting position can be provided for the adjusting pad, so as to install the adjusting pad.

[0016] The adjusting pad includes a limiting part and a supporting part, wherein the limiting part can be embedded in the mounting plate to fix the position of the adjusting pad. The supporting part is arranged toward the terminal and can abut against the terminal when the busbar is not plugged in to achieve support for the terminal.

[0017] Optionally, a clamping groove is provided on one side of the mounting plate facing the terminal, and the clamping groove has a groove bottom, and a first groove wall and a second groove wall opposite to each other.

[0018] In the sliding direction of the terminal, the projection of the first groove wall partially overlaps with the projection of the groove bottom, and / or, in the sliding direction of the terminal, the projection of the second groove wall partially overlaps with the projection of the groove bottom.

[0019] The limiting portion is embedded in the clamping groove and abuts against the groove bottom, the first groove wall and the second groove wall.

[0020] When the terminal assembly is plugged with a busbar, the first slot wall and / or the second slot wall can block the movement of the limiting portion in the sliding direction of the terminal, thereby reducing the possibility of the limiting portion being detached from the clamping slot.

[0021] Optionally, the accommodating cavity has a first cavity wall and a second cavity wall opposite to each other, a third cavity wall is connected between the first cavity wall and the second cavity wall, and the socket is arranged on the third cavity wall. A first limiting column is arranged on the first cavity wall, and a second limiting column is arranged on the second cavity wall, and the first limiting column and the second limiting column are arranged in a staggered manner.

[0022] There are multiple adjusting pads, some of which are opposite to the first limiting column and are located between one end of the first limiting column away from the first cavity wall and the second cavity wall. Another part of the adjusting pads are opposite to the second limiting column and are located between one end of the second limiting column away from the second cavity wall and the first cavity wall.

[0023] The two ends of some adjustment pads can respectively abut against the first limiting column and the second cavity wall, and the two ends of other adjustment pads can respectively abut against the second limiting column and the first cavity wall, so as to limit the adjustment pads in the arrangement direction of the first cavity wall and the second cavity wall.

[0024] Optionally, the shell includes a base and a cover, and the base and the cover are buckled together to form a receiving cavity.

[0025] The socket is arranged on a side of the base facing the cover body, and / or the socket is arranged on a side of the cover body facing the base.

[0026] By configuring the shell to include a base and a cover that can be buckled with each other, the socket on the shell can be configured in different ways.

[0027] Optionally, the terminal includes a wiring frame and a wiring baffle, the wiring frame has a wiring space inside, and the second end abuts the wiring frame. The wiring baffle is fixedly connected to the wiring frame and faces the socket, the wiring baffle covers part of the socket, and the other part of the socket is used to plug the busbar.

[0028] During the plugging process of the bus, the bus extends into the accommodating cavity through the other part of the socket to push the wiring baffle, and the wiring baffle pushes the elastic member through the wiring frame, so that the bus extends into the wiring space and abuts against the wiring frame.

[0029] The wiring frame can provide a wiring space for the busbar. During the plugging process of the busbar, the busbar can extend into the wiring space inside the wiring frame and abut against the wiring frame to achieve electrical connection between the busbar and the terminal.

[0030] The wiring baffle and the socket cooperate to form a space for the busbar to enter the accommodating cavity. The wiring baffle can cover part of the socket, and the other part of the socket is not covered by the wiring baffle, so as to form a space for plugging the busbar.

[0031] Optionally, the terminal further comprises a guide post, a guide hole is provided on one side of the wiring frame facing the elastic member, the guide post is passed through the guide hole, and a portion of the guide post extends out of the wiring frame. The elastic member is sleeved on the guide post, and the guide post is used to guide the expansion and contraction of the elastic member.

[0032] In this way, the guide column can guide the extension and retraction of the elastic member, thereby reducing the possibility of the elastic member being offset during the extension and retraction process.

[0033] Optionally, the terminal further includes an adjusting member. In the sliding direction of the terminal, the wiring frame has opposite first and second plates. The second plate abuts against the second end, and the wiring baffle is fixed to the second plate. An adjusting hole is provided on the first plate. The adjusting member passes through the adjusting hole and can move along the sliding direction of the terminal.

[0034] A wiring port is further provided on the cavity wall of the accommodating cavity. The wiring port faces the wiring space and is used to connect a wire. A wiring board is connected to the adjusting member. The wiring board is located on the side close to the wiring port. The adjusting member can drive the wiring board to move so that the wiring board blocks the wiring port or is misaligned with the wiring port.

[0035] In this way, the adjusting member can drive the wiring board to move, so that the relative position between the wiring board and the wiring port changes. When the wiring board is misaligned with the wiring port, part of the wiring space can be exposed through the wiring port. At this time, a wire can be connected into the wiring space through the wiring port.

[0036] In a second aspect, the present application provides a circuit breaker, which includes the wiring terminal assembly according to any one of the above first aspects.

[0037] For the circuit breaker provided in the above second aspect and each possible design of the above second aspect, the beneficial effects can refer to the beneficial effects brought by the above first aspect and each possible implementation manner of the first aspect, which will not be elaborated here.

[0058] An embodiment of the present application provides a circuit breaker, which includes a terminal block assembly 100 as Figure 1 shown.

[0059] In the circuit breaker equipped with the above terminal block assembly 100, the busbar can be inserted through the terminal block assembly 100, improving the convenience of busbar insertion, and it can adapt to the insertion of busbars of different specifications, improving the versatility of the circuit breaker.

[0060] The following will introduce the terminal block assembly 100 provided by the embodiment of the present application in detail with reference to the drawings.

[0061] Referring to Figure 1 shown, the operating handle mechanism includes a housing 10, a terminal 20 and an elastic member 30. The housing 10 has an accommodation cavity 11 inside, and a socket 101 is provided on the cavity wall of the accommodation cavity 11, and the socket 101 communicates with the outside of the housing 10. The terminal 20 is slidably arranged in the accommodation cavity 11, and part of the terminal 20 is opposite to the socket 101, and a wiring space 21 is provided inside the terminal 20. The elastic member 30 has opposite first end 31 and second end 32, the first end 31 abuts against the cavity wall of the accommodation cavity 11, and the second end 32 abuts against the terminal 20.

[0062] The socket 101 is used for inserting the busbar. During the insertion process of the busbar, the busbar pushes the elastic member 30 through the terminal 20, so that different parts of the wiring space 21 are opposite to the socket 101, and the busbar extends into the wiring space 21 through the socket 101 and abuts against the terminal 20.

[0063] The housing 10 can provide an installation space for the terminal 20 and the elastic member 30. Thus, the terminal 20 and the elastic member 30 can be installed in the accommodation cavity 11 in the housing 10.

[0064] The cavity wall of the accommodation cavity 11 is provided with the socket 101. Since the socket 101 communicates with the outside of the housing 10, the busbar can extend into the accommodation cavity 11 through the socket 101 and be connected to the terminal 20 in the accommodation cavity 11 to realize the electrical connection between the busbar and the terminal 20.

[0065] In the embodiment of the present application, the terminal 20 can be slidably arranged in the accommodation cavity 11 through the elastic member 30. When the terminal 20 slides under force, the terminal 20 can push against the elastic member 30 through the second end 32, so that the elastic member 30 is compressed.

[0066] During the sliding process of the terminal 20, the position of the wiring space 21 inside the terminal 20 can change, so that the relative position between the wiring space 21 and the socket 101 changes accordingly.

[0067] When inserting the bus bar into the terminal block assembly 100, the bus bar can enter the accommodation cavity 11 through the socket 101. At the same time, the bus bar can apply a force to the terminal 20, so that the terminal 20 slides and pushes against the elastic member 30. During the sliding process of the terminal 20, the position of the wiring space 21 also changes accordingly.

[0068] When the terminal 20 slides to a position where the wiring space 21 is opposite to the socket 101 and a part of the wiring space 21 opposite to the socket 101 is adapted to the bus bar, the bus bar can extend into the wiring space 21 and abut against the terminal 20. In this way, the insertion of the bus bar can be realized, so that the bus bar is electrically connected to the terminal 20.

[0069] Therefore, in the terminal block assembly 100 provided in the embodiment of the present application, the bus bar can push against the terminal 20 to change the position of the terminal 20 and the socket 101, so that the wiring space 21 can be opposite to the socket 101. In this way, a part of the wiring space 21 opposite to the socket 101 can be exposed to facilitate the insertion of the bus bar.

[0070] Since the terminal 20 is installed through the elastic member 30, when the terminal 20 slides, it can push against the elastic member 30, so that the elastic member 30 can be compressed.

[0071] For bus bars of different specifications, after the bus bar pushes against the terminal 20, the sliding distance of the terminal 20 is different, and the compression degree of the elastic member 30 can also be different. In this way, the relative part between the terminal 20 and the socket 101 is also different, which can adapt to the insertion of bus bars of different specifications and improve the versatility of the terminal block assembly 100.

[0072] For the sake of convenience of description, as Figure 1 shown, the direction from the terminal 20 to the elastic member 30 is called the first direction X, and the direction from the elastic member 30 to the terminal 20 is called the reverse of the first direction X.

[0073] In the embodiment of the present application, during the process that the bus bar pushes against the terminal 20 to make the terminal 20 squeeze the elastic member 30, the terminal 20 can slide along the first direction X.

[0074] During the process of removing the busbar, the contact between the busbar and the terminal 20 decreases. Under the action of its own elastic force, the elastic member 30 pushes the terminal 20 to slide in the reverse direction of the first direction X, so that the terminal 20 can slide to the position when the busbar is not inserted.

[0075] Moreover, the arrangement of the elastic member 30 can also make the electrical connection between the busbar and the terminal 20 more reliable.

[0076] Specifically, when the busbar is located in the wiring space 21, the elastic member 30 has a tendency to recover its deformation under the action of its own elasticity, and can apply a force in the reverse direction of the first direction X to the terminal 20, so that the terminal 20 can be in reliable contact with the busbar.

[0077] It should be noted that the elastic member 30 can be a spring, a spring sheet or other components made of elastic materials. The specific type of the elastic member 30 is not specifically limited in the embodiments of the present application.

[0078] In some embodiments, as Figure 1 and Figure 2 shown, the housing 10 may include a base 13 and a cover 14, and the base 13 and the cover 14 are fastened together to form a receiving cavity 11. The socket 101 is disposed on one side of the base 13 facing the cover 14, and / or the socket 101 is disposed on one side of the cover 14 facing the base 13.

[0079] The housing 10 includes a base 13 and a cover 14 that can be fastened to each other. Thus, the aforementioned terminal 20, elastic member 30, adjusting pad 40, etc. can all be disposed between the base 13 and the cover 14.

[0080] When the housing 10 includes a base 13 and a cover 14, the socket 101 on the housing 10 can be arranged in different ways.

[0081] Specifically, the socket 101 can be disposed on one side of the base 13 facing the cover 14. Alternatively, the socket 101 can also be disposed on one side of the cover 14 facing the base 13.

[0082] Or, the socket 101 can be disposed on one side of the base 13 facing the cover 14 and on one side of the cover 14 facing the base 13.

[0083] Specifically, a first groove can be provided on one side of the base 13 facing the cover 14, and a second groove can be provided on one side of the cover 14 facing the base 13. The first groove and the second groove are opposite and communicate with each other to form the socket 101, as Figure 2 shown.

[0084] The specific arrangement of the socket 101 can be selected according to the actual situation, and is not specifically limited in the embodiments of the present application.

[0085] In some embodiments, Figure 1 As shown, the terminal assembly 100 may further include an adjusting pad 40 , which is disposed on a side of the terminal 20 away from the elastic member 30 , and an end of the adjusting pad 40 away from the terminal 20 abuts against the housing 10 .

[0086] When the socket 101 is not plugged with a busbar, the end of the adjusting block 40 facing the terminal 20 abuts against the terminal 20 , and the adjusting block 40 presses the elastic member 30 through the terminal 20 , so that the elastic member 30 is in a compressed state.

[0087] Through the above arrangement, when the busbar is not plugged in, the two ends of the terminal 20 are respectively in contact with the adjustment pad 40 and the elastic member 30. Therefore, the adjustment pad 40 and the elastic member 30 can support the terminal 20 on both sides of the terminal 20.

[0088] Furthermore, the adjusting pad 40 can also provide a force along the first direction X to the terminal 20 and the elastic member 30 , so that the elastic member 30 can be in a pre-stressed state.

[0089] In this way, when the busbar is not plugged in, the elastic member 30 can provide the terminal 20 with a force in the opposite direction along the first direction X, so that the terminal 20 can be in reliable contact with the adjustment pad 40 .

[0090] Of course, in addition to the arrangement of the adjusting pad 40 , the terminal 20 facing away from the elastic member 30 may be supported in other ways, so that the position of the terminal 20 in the accommodating cavity 11 is relatively stable when the bus is not plugged in.

[0091] For example, the side of the terminal 20 facing away from the elastic member 30 may directly abut against the cavity wall of the accommodating cavity 11 .

[0092] Alternatively, a spring may be provided on the side of the terminal 20 away from the elastic member 30. The spring and the elastic member 30 are respectively connected to the two ends of the terminal 20. The two may cooperate to allow the terminal 20 to slide in the accommodating cavity 11 and improve the smoothness of the sliding of the terminal 20.

[0093] Specifically, during the process of plugging the bus, the terminal 20 slides along the first direction X to compress the elastic member 30 and stretch the spring. During the process of removing the bus, the elastic member 30 stretches under its own elasticity, and the spring contracts under its own elasticity, so that the terminal 20 slides in the opposite direction of the first direction X.

[0094] In some embodiments, Figure 1 and Figure 3As shown, a mounting plate 12 may be provided in the housing 10, and the mounting plate 12 is located on the side of the terminal 20 away from the elastic member 30. The adjusting spacer 40 includes a limiting portion 41 and a supporting portion 42 connected to each other, and the limiting portion 41 and the supporting portion 42 are distributed along the sliding direction of the terminal 20. The limiting portion 41 is embedded in the mounting plate 12, and the supporting portion 42 extends out of the mounting plate 12. The supporting portion 42 is used to abut against the terminal 20 when the bus bar is not inserted into the socket 101.

[0095] By providing the mounting plate 12 in the housing 10, a setting position can be provided for the adjusting spacer 40 so as to mount the adjusting spacer 40.

[0096] When the housing 10 includes a base 13 and a cover 14, the mounting plate 12 can be provided on the base 13, or can also be provided on the cover 14. Or, the mounting plate 12 can also be composed of two parts, one part is provided on the base 13 and the other part is provided on the cover 14.

[0097] The limiting portion 41 can be embedded in the mounting plate 12 to fix the position of the adjusting spacer 40.

[0098] The supporting portion 42 is arranged towards the terminal 20 and can abut against the terminal 20 when the bus bar is not inserted, so as to support the terminal 20.

[0099] In the embodiment of the present application, the adjusting spacer 40 only supports the terminal 20 when the bus bar is not inserted.

[0100] Specifically, when the bus bar is not inserted, the supporting portion 42 abuts against the terminal 20 to provide support. If the bus bar is inserted into the terminal block assembly 100, the terminal 20 will slide in the receiving cavity 11, so that the terminal 20 is separated from the supporting portion 42. At this time, the terminal 20 is supported by both the bus bar and the elastic member 30, and the adjusting spacer 40 cancels the support for the terminal 20.

[0101] In the embodiment of the present application, the adjusting spacer 40 is embedded in the mounting plate 12 through the limiting portion 41, and the connection between the adjusting spacer 40 and the limiting portion 41 is a detachable connection. Therefore, when the bus bar is inserted, in the sliding direction of the terminal 20, the adjusting spacer 40 may fall off the mounting plate 12.

[0102] At this time, since the adjusting spacer 40 is separated from the terminal 20, the adjusting spacer 40 is in a free state and is likely to shift in the receiving cavity 11. This will cause problems that it is not easy for the adjusting spacer 40 to abut against the terminal 20 and it is not easy for the adjusting spacer 40 to be embedded in the mounting plate 12 again after the bus bar is removed.

[0103] To reduce the possibility of the adjusting spacer 40 falling off the mounting plate 12, the present application further improves the setting manner of the limiting portion 41 and the mounting plate 12 as follows.

[0104] As Figure 1 , Figures 3 to 5 shown, a clamping groove 121 may be provided on the side of the mounting plate 12 facing the terminal 20. The clamping groove 121 has a groove bottom 122, and opposite first and second groove walls 123 and 124. The limiting portion 41 may be embedded in the clamping groove 121 and abut against the groove bottom 122, the first groove wall 123, and the second groove wall 124.

[0105] Since, in the sliding direction of the terminal 20, the projection of the first groove wall 123 overlaps with the projection of the groove bottom 122, and / or, in the sliding direction of the terminal 20, the projection of the second groove wall 124 overlaps with the projection of the groove bottom 122. Therefore, when the limiting portion 41 is embedded in the clamping groove 121, the first groove wall 123 and / or the second groove wall 124 can limit the limiting portion 41 and reduce the movement of the adjusting spacer 40 in the sliding direction of the terminal 20.

[0106] So when the bus bar is inserted into the terminal block assembly 100, the first groove wall 123 and / or the second groove wall 124 can also block the movement of the limiting portion 41 in the sliding direction of the terminal 20 and reduce the possibility of the limiting portion 41 disengaging from the clamping groove 121.

[0107] Thus, even if the supporting portion 42 is separated from the terminal 20, the adjusting spacer 40 can still maintain an embedded relationship with the mounting plate 12, which is convenient for the abutment between the terminal 20 and the adjusting spacer 40 after the bus bar is removed subsequently.

[0108] Among them, as Figure 5 shown, the projection of the first groove wall 123 overlaps with the projection of the groove bottom 122, which can be specifically achieved by setting the angle between the first groove wall 123 and the groove bottom 122 to be an acute angle.

[0109] Continuing to refer to Figure 5 , the projection of the second groove wall 124 overlaps with the projection of the groove bottom 122, which can also be achieved by setting the angle between the second groove wall 124 and the groove bottom 122 to be an acute angle.

[0110] The limiting portion 41 abuts against the groove bottom 122, the first groove wall 123, and the second groove wall 124, which can be achieved by setting the shape of the limiting portion 41 to be adapted to the shape of the clamping groove 121, as Figure 3 and Figure 5 shown.

[0111] In the embodiment of the present application, it is possible to set only the projection of the first groove wall 123 to partially overlap with the projection of the groove bottom 122. At this time, the first groove wall 123 limits the limiting portion 41 on one side thereof. To ensure the limiting effect, the angle between the first groove wall 123 and the groove bottom 122 can be relatively small, so that the contact portion between the first groove wall 123 and the limiting portion 41 is relatively large.

[0112] Alternatively, it is also possible to set only the projection of the second groove wall 124 to partially overlap with the projection of the groove bottom 122. At this time, the second groove wall 124 limits the limiting portion 41 on one side thereof. To ensure the limiting effect, the angle between the second groove wall 124 and the groove bottom 122 can be relatively small, so that the contact portion between the second groove wall 124 and the limiting portion 41 is relatively large.

[0113] Or, it is possible to set the projection of the first groove wall 123 to partially overlap with the projection of the groove bottom 122, and at the same time set the projection of the second groove wall 124 to partially overlap with the projection of the groove bottom 122, as Figure 5 shown. At this time, both the first groove wall 123 and the second groove wall 124 are inclined relative to the groove bottom 122, so that the clamping groove 121 is wedge-shaped, and the first groove wall 123 and the second groove wall 124 can limit the limiting portion 41 on both sides, and the limiting effect is better.

[0114] The arrangement direction of the first groove wall 123 and the second groove wall 124 is defined as the second direction Y. The clamping groove 121 proposed in the present application is adapted to the adjusting cushion block 40, so that the adjusting cushion block 40 can be limited in both the first direction X and the second direction Y.

[0115] It should be noted that multiple clamping grooves 121 can be provided on the mounting plate 12. In this way, multiple adjusting cushion blocks 40 can be provided, and the multiple adjusting cushion blocks 40 can all support the terminal 20, improving the stability of the terminal 20 in the receiving cavity 11.

[0116] For example, the number of the clamping grooves 121 can be 2, 3, 4, etc. Of course, the number of the clamping grooves 121 can also be 1. The specific number of the clamping grooves 121 on the mounting plate 12 is not specifically limited in the embodiment of the present application.

[0117] In some embodiments, as Figure 2 、 Figure 4 and Figure 6 shown, the receiving cavity 11 can have opposite first cavity walls 111 and second cavity walls 112, and a third cavity wall is also connected between the first cavity walls 111 and the second cavity walls 112, and the socket 101 is provided on the third cavity wall.

[0118] Among them, as Figure 1 、 Figure 4 and Figure 6As shown, the arrangement direction of the first cavity wall 111 and the second cavity wall 112 is the third direction Z.

[0119] The socket 101 is arranged on the third cavity wall. Since the third cavity wall is located between the first cavity wall 111 and the second cavity wall 112, the terminal 20 can also be located between the first cavity wall 111 and the second cavity wall 112, so that the terminal 20 can be opposite to the socket 101 for plugging the bus bar.

[0120] As Figure 4 and Figure 6 shown, a first limiting post 114 is arranged on the first cavity wall 111, and a second limiting post 115 is arranged on the second cavity wall 112. The first limiting post 114 and the second limiting post 115 are arranged in a staggered manner.

[0121] The number of the adjusting pads 40 is multiple. Some of the adjusting pads 40 are opposite to the first limiting post 114 and are located between the end of the first limiting post 114 away from the first cavity wall 111 and the second cavity wall 112. Some other adjusting pads 40 are opposite to the second limiting post 115 and are located between the end of the second limiting post 115 away from the second cavity wall 112 and the first cavity wall 111.

[0122] In this way, in the third direction Z, both ends of some of the adjusting pads 40 can be abutted against the first limiting post 114 and the second cavity wall 112 respectively, and both ends of some other adjusting pads 40 can be abutted against the second limiting post 115 and the first cavity wall 111 respectively, realizing the limiting of the adjusting pads 40 in the third direction Z.

[0123] Based on this, the possibility that the adjusting pads 40 shift in the third direction Z and lose the supporting effect on the terminal 20 can be reduced.

[0124] In the embodiment of the present application, the clamping groove 121 can limit the adjusting pads 40 in the first direction X and the second direction Y, and the first limiting post 114, the second limiting post 115, the first cavity wall 111 and the second cavity wall 112 can limit the adjusting pads 40 in the third direction Z, so that the adjusting pads 40 are fixed in position in the accommodating cavity 11.

[0125] Of course, in addition to the above settings, the first limiting post 114 can also be arranged only on the first cavity wall 111, and the second limiting post 115 is not arranged on the second cavity wall 112. At this time, multiple first limiting posts 114 are opposite to multiple adjusting pads 40.

[0126] Or, the second limiting post 115 can also be arranged only on the second cavity wall 112, and the first limiting post 114 is not arranged on the first cavity wall 111. At this time, multiple second limiting posts 115 are opposite to multiple adjusting pads 40.

[0127] The first cavity wall 111 is the surface of the base 13 facing the cover 14 , and the second cavity wall 112 is the surface of the cover 14 facing the base 13 .

[0128] In some embodiments, Figure 1 , Figure 7 and Figure 8 As shown, the terminal 20 may include a wiring frame 22 and a wiring baffle 23, wherein the wiring frame 22 has a wiring space 21 inside, and the second end 32 abuts against the wiring frame 22. The wiring baffle 23 is fixedly connected to the wiring frame 22 and faces the socket 101, and the wiring baffle 23 covers part of the socket 101, and the other part of the socket 101 is used to plug the busbar.

[0129] During the plugging process of the bus, the bus extends into the accommodating cavity 11 through the other part of the socket 101 to push the wiring baffle 23, and the wiring baffle 23 pushes the elastic member 30 through the wiring frame 22, so that the bus extends into the wiring space 21 and abuts against the wiring frame 22.

[0130] The wiring frame 22 can provide a wiring space 21 for plugging in the bus. During the plugging process of the bus, the bus can extend into the wiring space 21 and abut against the wiring frame 22 to achieve electrical connection between the bus and the terminal 20.

[0131] The wiring baffle 23 cooperates with the socket 101 to form a space for the busbar to enter the accommodating cavity 11. Specifically, the wiring baffle 23 can cover part of the socket 101, and the other part of the socket 101 is not covered by the wiring baffle 23, so as to form a space for plugging the busbar. Figure 1 and Figure 2 shown.

[0132] During the plugging process of the bus, the user can push the bus into the housing 10 along the straight line direction where the second direction Y is located. The bus can first extend into the part of the socket 101 that is not blocked by the wiring baffle 23. As the bus continues to be pushed, the bus can apply force to the wiring baffle 23, so that the wiring baffle 23 drives the wiring frame 22 to slide along the first direction X.

[0133] When the wiring frame 22 slides to the wiring space 21 and faces the bus, the bus can extend into the wiring space 21 and abut against the wiring frame 22, and the insertion of the bus is completed.

[0134] In addition, when the terminal assembly 100 includes the adjustment block 40 , the adjustment block 40 may abut against a side of the terminal 20 that is away from the elastic member 30 .

[0135] Since the adjusting spacer 40 can adjust the preloading degree of the elastic member 30. Therefore, in the case where the busbar is not plugged in, the terminal 20 can be positioned at different positions by adjusting the spacer 40, so that the wiring baffle 23 is in different positions, thereby changing the portion of the socket 101 that is not blocked by the wiring baffle 23.

[0136] Specifically, by setting the adjusting spacer 40 to have different lengths, the preloading degree of the elastic member 30 can be made different, so that the wiring baffle 23 is located at different positions. In this way, when the busbar is not plugged in, the socket 101 that is not blocked by the wiring baffle 23 can be adjusted.

[0137] Based on this, the length of the adjusting spacer 40 can be set according to the specifications of the busbar to be plugged in, so that the socket 101 that is not blocked by the wiring baffle 23 is adapted to the specifications of the busbar.

[0138] Thus, it is possible to reduce the possibility that the socket 101 that is not blocked by the wiring baffle 23 is too small, resulting in the busbar being unable to be plugged in and the need for additional tools. It is also possible to reduce the possibility that the socket 101 that is not blocked by the wiring baffle 23 is too large, resulting in the busbar being unable to push against the terminal 20 when the busbar is plugged in.

[0139] Wherein, the length of the adjusting spacer 40 is the dimension of the adjusting spacer 40 at opposite ends in the first direction X.

[0140] In the case where the adjusting spacer 40 includes a limiting portion 41 and a supporting portion 42, the supporting portion 42 can have different lengths to adjust the socket 101 that is not blocked by the wiring baffle 23, so that the socket 101 that is not blocked by the wiring baffle 23 can be adapted to the busbar.

[0141] It should be noted that the wiring baffle 23 can be misaligned with the wiring space 21. Refer to Figure 1 and Figure 7 , the wiring baffle 23 can be connected to the side of the wiring frame 22 facing the elastic member 30, which can reduce the possibility that after the busbar is plugged in, it abuts against the wiring baffle 23 and cannot abut against the inner surface of the wiring frame 22.

[0142] Wherein, the wiring baffle 23 can be flush with the inner surface of the wiring frame 22 close to the elastic member 30, or can also be lower than the inner surface of the wiring frame 22 close to the elastic member 30.

[0143] In some embodiments, such as Figure 1 、 Figures 7 to 9As shown, the terminal 20 further includes a guiding post 24. A guiding hole 221 is provided on one side of the wiring frame 22 facing the elastic member 30. The guiding post 24 passes through the guiding hole 221, and a part of the guiding post 24 extends outside the wiring frame 22. The elastic member 30 is sleeved on the guiding post 24, and the guiding post 24 is used to guide the expansion and contraction of the elastic member 30.

[0144] Since a part of the guiding post 24 extends outside the wiring frame 22, when the elastic member 30 is arranged, the side of the elastic member 30 facing the wiring frame 22 can be sleeved on the guiding post 24. Thus, the guiding post 24 can guide the expansion and contraction of the elastic member 30, reducing the possibility of the elastic member 30 deviating during the expansion and contraction process.

[0145] It should be noted that for the convenience of connecting the guiding post 24 and the wiring frame 22. The guiding hole 221 can be a threaded hole, and an external thread is provided on the side of the guiding post 24 facing away from the elastic member 30. In this way, the guiding post 24 and the guiding hole 221 can be connected in a threaded connection manner. At this time, for the convenience of setting the thread in the guiding hole 221, the guiding hole 221 can be a through hole.

[0146] At this time, for the convenience of applying force to the guiding post 24 to thread-connect the guiding post 24 and the guiding hole 221, the side of the guiding post 24 facing away from the wiring frame 22 can be in the shape of a cuboid, or an irregular cylinder shape, etc. For example, referring to Figure 9 , a plane can also be machined on the side surface of the cylinder for easy gripping and applying force.

[0147] Moreover, a stepped hole can also be provided on the guiding post 24 to control the feed depth when threading the external thread.

[0148] Of course, the guiding hole 221 and the guiding post 24 can also be connected in other ways. For example, the guiding hole 221 is a smooth hole. After the guiding post 24 is inserted into the guiding hole 221, the part of the guiding post 24 located in the wiring space 21 can be upset.

[0149] It should also be noted that to further reduce the possibility of the elastic member 30 deviating during the expansion and contraction process, a receiving groove 16 can also be provided on the base 13 and / or the cover 14. The elastic member 30 can be located in the receiving groove 16, and the receiving groove 16 can also limit the elastic member 30, as Figure 4 and Figure 6 shown.

[0150] Furthermore, as Figure 4 shown, ribs 161 can also be provided on the groove wall of the receiving groove 16. When the elastic member 30 is a spring, the ribs 161 can be embedded between the coils of the spring, which can reduce the possibility of the elastic member 30 coming out of the receiving groove 16 when the terminal 20 moves away from the elastic member 30.

[0151] In addition, a chute 17 may be provided on the base 13 and / or the cover 14, and the chute 17 faces the wiring baffle 23. During the sliding of the terminal 20 in the first direction X, the wiring baffle 23 can slide into the chute 17, as Figure 4 and Figure 6 shown.

[0152] In this way, on the one hand, it can provide a sliding space for the sliding of the wiring baffle 23, reducing the possibility of the sliding of the wiring baffle 23 being blocked when inserting the busbar. On the other hand, when the terminal 20 slides a large amount, the chute 17 can guide the sliding of the wiring baffle 23, and thus play a role in guiding the terminal 20.

[0153] In some embodiments, as Figure 7 and Figure 8 shown, the terminal 20 further includes an adjusting member 25. In the sliding direction of the terminal 20, the wiring frame 22 has opposite first plate 26 and second plate 27. The second plate 27 abuts against the second end 32, and the wiring baffle 23 is fixed to the second plate 27. An adjusting hole 222 is provided on the first plate 26, and the adjusting member 25 passes through the adjusting hole 222 and can move along the sliding direction of the terminal 20.

[0154] As Figure 1 , Figure 4 and Figure 6 shown, a wiring port 15 is further provided on the cavity wall of the accommodating cavity 11. The wiring port 15 faces the wiring space 21, and the wiring port 15 is used to connect a wire.

[0155] As Figure 1 and Figure 7 shown, a wiring board 28 is connected to the adjusting member 25. The wiring board 28 is located on the side close to the wiring port 15. The adjusting member 25 can drive the wiring board 28 to move so that the wiring board 28 blocks the wiring port 15 or is misaligned with the wiring port 15.

[0156] In this way, the adjusting member 25 can drive the wiring board 28 to move, so that the relative position between the wiring board 28 and the wiring port 15 is changed. When the wiring board 28 is misaligned with the wiring port 15, a part of the wiring space 21 can be exposed through the wiring port 15. At this time, a wire can be connected into the wiring space 21 through the wiring port 15.

[0157] That is to say, in the present application, the terminal 20 can be connected to a wire and a busbar at the same time, which can expand the use range of the circuit breaker and facilitate wiring.

[0158] It should be noted that, in order to facilitate the control of the movement of the adjusting member 25, the adjusting member 25 can be a threaded member, and an internal thread can be provided in the adjusting hole 222. Therefore, when it is necessary to control the movement of the adjusting member 25, the threaded member can be rotated.

[0159] To make the structure and principle of this application clearer, the use of the terminal block assembly 100 will be described herein in conjunction with it.

[0160] When it is necessary to plug in the bus bar and the wire, the adjusting member 25 can be first controlled to move away from the elastic member 30, so that the adjusting member 25 withdraws from the installation space. Secondly, the bus bar can be plugged into the socket 101, and the wire can be inserted into the wiring port 15. After that, the adjusting member 25 can be controlled to move towards the elastic member 30, so that the wire and the bus bar can be connected.

[0161] In addition, when the terminal block assembly 100 proposed in this application is applied, it is not limited to connecting the wire and the bus bar at the same time, and only the bus bar can also be connected. At this time, the adjusting member 25 can also be first controlled to move away from the elastic member 30, then the bus bar can be plugged into the socket 101, and after that, the adjusting member 25 can be controlled to move towards the elastic member 30, so that the adjusting member 25 abuts against the bus bar, realizing the connection between the bus bar and the terminal 20.

[0162] It should also be noted that multiple terminals 20 can be provided in the housing 10. At each terminal 20, an elastic member 30 can be connected to adapt to bus bars of different specifications. Refer to Figure 1 , two terminals 20 are provided in the figure, and both terminals 20 can adjust the size of the socket 101 not blocked by the wiring baffle 23 through the elastic member 30.

[0163] In the terminal block assembly 100 provided in the embodiment of this application, the bus bar can push against the terminal 20 to change the position of the terminal 20 and the socket 101, so that the wiring space 21 can be opposite to the socket 101. In this way, a part of the wiring space 21 opposite to the socket 101 can be exposed to facilitate the plugging of the bus bar.

[0164] For bus bars of different specifications, the sliding distances of the terminals 20 after the bus bars push against the terminals 20 are different, which can also make the compression degrees of the elastic members 30 different. In this way, the relative parts of the terminals 20 and the sockets 101 are also different, which can adapt to the plugging of bus bars of different specifications and improve the versatility of the terminal block assembly 100.

[0165] Finally, it should be noted that: the above embodiments are only specific implementation manners of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
