Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, and in particular to a wiring assembly and a circuit breaker. Background Technology

[0002] A low-voltage circuit breaker (formerly known as an automatic switch) is a switching device that can connect and disconnect not only normal load current and overload current, but also short-circuit current. Low-voltage circuit breakers are typically connected to external conductors via wiring assemblies.

[0003] In related technologies, wiring assemblies typically include a rectangular frame and screws threaded to the frame. The screws can crimp external conductors into the frame using their threaded ends or a crimping plate. However, in vibration-prone environments such as rail transit, construction sites, and reciprocating or rotating machinery, the clamping of the wiring assembly onto the conductors may loosen under the influence of vibration, leading to conductor detachment and line faults.

The supporting part, the first connecting part, the second crimping part, the second connecting part, and the third connecting part are bent into shape in sequence. The third connecting part overlaps the supporting part. A wiring channel is formed between the supporting part, the first connecting part, the second crimping part, and the second connecting part. The first crimping part passes through the wiring channel, and the first connecting part and the second connecting part form a limiting fit with the first crimping part to restrict the rotation of the wiring frame.

[0012] Optionally, the third connecting part is provided with a positioning hole, the supporting part is provided with a flange hole, the flange of the flange hole is inserted into the positioning hole, and the screw part passes through the flange hole and is threadedly connected to the flange hole.

[0013] Optionally, the limiting platform is provided with a first through hole through which the screw part can pass, the diameter of the first through hole is larger than the diameter of the screw part, and the diameter of the first through hole is smaller than the diameter of the head;

[0014] And / or, the first crimping portion is provided with a second through hole through which the screw portion can pass, and the diameter of the second through hole is larger than the diameter of the screw portion.

The small end of the first threaded sleeve is inserted into the first connecting hole, and the large end of the first threaded sleeve is located on the side of the support portion near the second pressing portion.

[0017] Optionally, the wiring frame further includes a first connecting part, a second connecting part, and a third connecting part. The supporting part, the first connecting part, the second crimping part, the second connecting part, and the third connecting part are bent in sequence. The third connecting part overlaps the supporting part. A wiring channel is formed between the supporting part, the first connecting part, the second crimping part, and the second connecting part. The first crimping part is inserted into the wiring channel.

[0018] The third connecting part is provided with a positioning hole, and the small end of the first threaded sleeve is sequentially inserted into the first connecting hole and the positioning hole.

[0019] Optionally, the second crimping portion is provided with a second connecting hole, and the threaded sleeve includes a second threaded sleeve. The second threaded sleeve is stepped, with the small end of the second threaded sleeve inserted into the second connecting hole, and the large end of the second threaded sleeve located on the side of the second crimping portion away from the support portion.

[0020] Optionally, the housing is provided with a limiting part, and the head is located between the limiting part and the limiting platform along the first direction.

[0022] Beneficial effects: The wiring assembly provided by this utility model allows for the following steps during wiring: First, the screw connector is tightened to disengage the screw portion from the second crimping portion. As the head of the screw connector abuts against the limiting platform, the wiring frame moves away from the head of the screw connector. The tail end of the screw portion and the first crimping portion both form a space with the second crimping portion to accommodate the wiring terminal. Then, the wiring terminal is inserted between the first and second crimping portions, and the screw connector is tightened in opposite directions. As the head of the screw connector abuts against the limiting platform, the wiring frame moves closer to the head of the screw connector. The screw portion of the screw connector passes through the through hole of the wiring terminal and is threadedly connected to the second crimping portion. As the screw connector is further tightened, the first and second crimping portions clamp the wiring terminal. When the first and second crimping parts clamp the terminal, the supporting part and the second crimping part tend to move away from each other, resulting in greater contact pressure between the first and second crimping parts and the screw part of the screw connector. Both the supporting part and the second crimping part are threadedly connected to the screw part of the screw connector, creating a larger threaded contact area between the terminal frame and the screw part of the screw connector. This improves the friction between the threads, enhancing the stability and reliability of the threaded fastening, thereby reducing the risk of thread loosening and ensuring stable and reliable wiring. Furthermore, the screw part of the screw connector passes through the through-hole of the terminal, which helps reduce the risk of the terminal detaching from the wiring assembly. In addition, compared to directly crimping external wires, the first and second crimping parts provide a more stable and reliable contact with the terminal, resulting in a more stable and reliable clamping of the terminal.

[0023] The circuit breaker provided by this utility model improves wiring stability and reliability through the arrangement of wiring components. Attached Figure Description

[0043] Reference Figures 1 to 6 As shown, this embodiment provides a wiring assembly, including a housing 100, a terminal block 200, a terminal frame 300, and a screw connector 400. Wherein, Figures 1 to 4 The image shows only a portion of the structure of the housing 100.

[0044] A limiting platform 110 is provided on the housing 100, and a terminal block 200 is fixed inside the housing 100. The terminal block 200 includes a first crimping portion 210. The terminal frame 300 includes a support portion 310 and a second crimping portion 320 spaced apart along a first direction. The support portion 310 is located between the limiting platform 110 and the first crimping portion 210, and the first crimping portion 210 is located between the support portion 310 and the second crimping portion 320. The screw connector 400 includes interconnected screw portions. The screw portion 410 and the head 420 are connected in a first direction. The limiting platform 110, the support portion 310, the first pressing portion 210 and the second pressing portion 320 are sequentially passed through the screw portion 410. The head 420 abuts against the limiting platform 110. The support portion 310 and the second pressing portion 320 are both threadedly connected to the screw portion 410. The first pressing portion 210 and the second pressing portion 320 can clamp the terminal 10. The screw portion 410 passes through the through hole 11 on the terminal 10.

[0045] For example, the screw connector 400 can be a screw, such as a Phillips head screw.

[0046] For example, the support portion 310, the first crimping portion 210 and the second crimping portion 320 are parallel to each other.

[0047] Understandably, the length of the screw portion 410 of the screw connector 400 extends along the first direction.

[0048] During wiring, the screw connector 400 can be tightened first to disengage the screw portion 410 from the second crimping portion 320. With the head 420 of the screw connector 400 abutting against the limiting platform 110, the wiring frame 300 moves away from the head 420 of the screw connector 400. The tail end of the screw portion 410 and the first crimping portion 210 both form space with the second crimping portion 320 to allow space for the wiring terminal 10. It is understood that the tool used to tighten the screw connector 400 will press against the head 420 of the screw connector 400, causing the head 420 of the screw connector 400 to abut against the limiting platform 110. Then, the terminal block 10 is inserted between the first crimping part 210 and the second crimping part 320, and the screw 400 is screwed in opposite directions. With the head 420 of the screw 400 abutting against the limiting platform 110, the wiring frame 300 moves close to the head 420 of the screw 400. The screw part 410 of the screw 400 passes through the through hole 11 of the terminal block 10 and is threadedly connected to the second crimping part 320. As the screw 400 is continued to be screwed, the first crimping part 210 and the second crimping part 320 clamp the terminal block 10. When the first crimping portion 210 and the second crimping portion 320 clamp the terminal 10, the supporting portion 310 and the second crimping portion 320 tend to move away from each other, resulting in a large contact pressure between the first crimping portion 210 and the second crimping portion 320 and the screw portion 410 of the screw connector 400. Both the supporting portion 310 and the second crimping portion 320 are threadedly connected to the screw portion 410 of the screw connector 400, creating a large threaded contact area between the terminal frame 300 and the screw portion 410 of the screw connector 400. This improves the friction between the threads, enhances the stability and reliability of the threaded fastening, and reduces the risk of thread loosening, ensuring stable and reliable wiring. Furthermore, the screw portion 410 of the screw connector 400 passes through the through hole 11 of the terminal 10, which helps reduce the risk of the terminal 10 detaching from the wiring assembly. In addition, compared to directly crimping external wires, the first crimping portion 210 and the second crimping portion 320 have a more stable and reliable contact with the terminal 10, resulting in a more stable and reliable clamping of the terminal 10. Understandably, terminal 10 is connected to an external wire.

[0049] Understandably, the screw portion 410 of the screw connector 400 passes through the through hole 11 of the terminal block 10. When the thread tightening is loose, but the screw portion 410 of the screw connector 400 has not disengaged from the second crimping portion 320, the terminal block 10 can also be hung on the screw portion 410 of the screw connector 400.

[0050] For example, the limiting platform 110 is provided with a first through hole 111 through which the screw portion 410 of the screw connector 400 can pass. The diameter of the first through hole 111 is larger than the diameter of the screw portion 410 to facilitate the screw portion 410 of the screw connector 400 passing through the first through hole 111. The diameter of the first through hole 111 is smaller than the diameter of the head 420 to ensure a stable and reliable contact between the head 420 of the screw connector 400 and the limiting platform 110.

[0051] For example, the first crimping portion 210 is provided with a second through hole 211 through which the screw portion 410 of the screw connector 400 can pass. The diameter of the second through hole 211 is larger than the diameter of the screw portion 410, so as to facilitate the screw portion 410 of the screw connector 400 to pass through the second through hole 211.

[0052] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the wiring frame 300 also includes a first connecting portion 330, a second connecting portion 340, and a third connecting portion 350. The support portion 310, the first connecting portion 330, the second crimping portion 320, the second connecting portion 340, and the third connecting portion 350 are sequentially bent into shape. The third connecting portion 350 overlaps the support portion 310. A wiring channel (not shown) is formed between the support portion 310, the first connecting portion 330, the second crimping portion 320, and the second connecting portion 340. The first crimping portion 210 passes through the wiring channel, facilitating the forming of the wiring frame 300 and aiding in the positioning and assembly of the wiring frame 300 and the wiring board 200. It is understood that the wiring frame 300 can be formed by bending sheet metal.

[0053] For example, the wiring channel extends along the second direction, and the first crimping portion 210 passes through the wiring channel along the second direction. The first and second directions are perpendicular to each other.

[0054] For example, a limiting fit is formed between the first connecting portion 330 and the second connecting portion 340 and the first crimping portion 210 to limit the rotation of the wiring frame 300, so as to prevent the wiring frame 300 from rotating with the screw connector 400, and to facilitate the clamping of the wiring assembly on the terminal 10.

[0055] For example, the support portion 310, the second crimping portion 320 and the third connecting portion 350 are all perpendicular to the first connecting portion 330, and the first connecting portion 330 and the second connecting portion 340 are parallel to each other.

[0056] For example, the third connecting part 350 is provided with a positioning hole 351, and the screw part 410 of the screw connector 400 passes through the positioning hole 351.

[0057] In one feasible implementation, the support portion 310 is provided with a flanged hole 311, and the flange 3111 of the flanged hole 311 is inserted into the positioning hole 351 to realize the connection between the support portion 310 and the third connecting portion 350. This connection is stable and reliable, and helps to reduce the risk of separation between the support portion 310 and the third connecting portion 350 due to deformation of the wiring frame 300.

[0058] For example, the support portion 310 and the third connecting portion 350 can be welded together.

[0059] For example, the screw portion 410 passes through the flanged hole 311 and is threadedly connected to the flanged hole 311. The flanged design of the flanged hole 311 helps to extend the thread length inside the flanged hole 311, which helps to improve the stability and reliability of the thread fastening.

[0060] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, at least one of the support portion 310 and the second pressing portion 320 is connected to a threaded sleeve. The threaded sleeve is threadedly connected to the screw portion 410. The threaded sleeve has a long thread length, which is beneficial to improving the stability and reliability of the threaded fastening.

[0061] In one feasible embodiment, the support portion 310 is provided with a first connecting hole (not shown), and the threaded sleeve includes a first threaded sleeve (not shown). The first threaded sleeve is stepped, with its small end inserted into the first connecting hole, and its large end located on the side of the support portion 310 near the second crimping portion 320. This helps to reduce the risk of the first threaded sleeve detaching from the support portion 310. It is understood that when the first crimping portion 210 and the second crimping portion 320 clamp the terminal 10, the large end of the first threaded sleeve presses against the support portion 310.

[0062] For example, the small end of the first threaded sleeve and the first connecting hole can be an interference fit between the shaft and the hole.

[0063] For example, the first threaded sleeve and the support portion 310 can be connected together by welding.

[0064] For example, the small end of the first threaded sleeve is sequentially inserted into the first connecting hole and the positioning hole 351 to realize the connection between the support part 310 and the third connecting part 350, which is stable and reliable and helps to reduce the risk of separation between the support part 310 and the third connecting part 350 due to the deformation of the wiring frame 300.

[0065] For example, the small end of the first threaded sleeve and the positioning hole 351 can be an interference fit with the shaft hole.

[0066] In one feasible embodiment, the second crimping portion 320 is provided with a second connecting hole 321, and the threaded sleeve includes a second threaded sleeve 500, which is stepped. The small end of the second threaded sleeve 500 is inserted into the second connecting hole 321, and the large end of the second threaded sleeve 500 is located on the side of the second crimping portion 320 away from the support portion 310, which helps to reduce the risk of the second threaded sleeve 500 detaching from the second crimping portion 320. It is understood that when the first crimping portion 210 and the second crimping portion 320 clamp the terminal 10, the large end of the second threaded sleeve 500 presses against the second crimping portion 320.

[0067] For example, the small end of the second threaded sleeve 500 and the second connecting hole 321 can be an interference fit with the shaft hole.

[0068] For example, the second threaded sleeve 500 and the second crimping portion 320 can be connected together by welding.

[0069] In some embodiments, such as Figure 7 As shown, the wiring frame 300 is provided with a protrusion 360, and the housing 100 is provided with a sliding groove (not shown). The protrusion 360 is slidably disposed in the sliding groove along the first direction, which helps to improve the stability of the wiring frame 300 moving along the first direction and facilitates the threaded connection between the screw portion 410 of the screw connector 400 and the second crimping portion 320. For example, it facilitates the screw portion 410 to pass through the second threaded sleeve 500 on the second crimping portion 320.

[0070] For example, both the first connecting portion 330 and the second connecting portion 340 are provided with protrusions 360. For instance, at least one protrusion 360 is provided on both sides of the first connecting portion 330 along the second direction and on both sides of the second connecting portion 340 along the second direction, which helps improve the stability of the wiring frame 300 moving along the first direction. Alternatively, at least two protrusions 360 spaced apart along the first direction are provided on both sides of the first connecting portion 330 and both sides of the second connecting portion 340 along the second direction. The protrusions 360 can be formed by bending and extending from the edges of the first connecting portion 330 and the second connecting portion 340.

[0071] In some embodiments, such as Figure 1 , Figure 3 and Figure 8As shown, the housing 100 is provided with a limiting part 120, and the head 420 is located between the limiting part 120 and the limiting platform 110 along the first direction. For example, screwing the screw connector 400 causes the screw portion 410 of the screw connector 400 to disengage from the second crimping portion 320. The tail end of the screw portion 410 of the screw connector 400 and the first crimping portion 210 both form a space for the terminal 10 to be placed between the second crimping portion 320. When the large end of the first threaded sleeve abuts against the first crimping portion 210, screwing the screw connector 400 continues, and the screw connector 400 moves away from the second crimping portion 320 until the head 420 of the screw connector 400 abuts against the limiting portion 120. At this time, the space for the terminal 10 to be placed between the tail end of the screw portion 410 of the screw connector 400 and the first crimping portion 210 and the second crimping portion 320 is maximized, which is more conducive to the insertion of the terminal 10 between the first crimping portion 210 and the second crimping portion 320, and effectively prevents the screw portion 410 of the screw connector 400 from disengaging from the first threaded sleeve.

[0072] This embodiment also provides a circuit breaker including a housing (not shown) and a wiring assembly provided in any of the above embodiments, the wiring assembly being disposed within the housing. In this embodiment, the circuit breaker, through the arrangement of the wiring assembly, helps to improve wiring stability and reliability.

[0073] In some embodiments, the housing is integrally formed with the housing 100 of the wiring assembly; in other words, the housing 100 of the wiring assembly is part of the housing.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
