Description

Technical Field

[0001] This utility model relates to the field of switch connector technology, and in particular to a wiring structure and a push-button switch. Background Technology

[0002] A push-button switch is a switch that uses a button to actuate a transmission mechanism, causing the moving contact to connect or disconnect with the stationary contact, thus switching the circuit. Push-button switches are simple in structure and widely used control electrical appliances. In electrical automatic control circuits, they are used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] According to existing technology, there is an anti-disconnection switch, publication number CN222868240U, which has a wire clamping groove on the bottom shell. One side of the wire clamping groove abuts against the side wall of the bottom shell. A first metal part and a second metal part are respectively provided on both sides of the wire clamping groove. A metal contact is hinged in the middle of the wire clamping groove. The fact that one side of the wire clamping groove abuts against the side of the bottom shell means that the wire can only connect to the terminal piece through the area between the other side of the wire clamping groove and the bottom shell. The wiring method is simple and inflexible. Moreover, there is no structure inside the bottom shell to limit the cable, which is inconvenient for cable arrangement.

[0004] In addition, two clamping claws are used to clamp the cable. The clamping claws need to be pressed down to clamp the cable and prevent it from coming off. However, if the pressing force deviates even slightly when pressing down on the clamping claws, it is easy to press the clamping claws off-center, which greatly reduces the clamping effect on the cable and makes it unreliable. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a wiring structure and push-button switch that are flexible in wiring and easy to arrange cables.

[0006] To achieve the above objectives, the technical solution of this utility model is: a wiring structure, comprising: The clamping part is used to clamp the cable. The clamping part has a first end and a second end in the radial direction of the clamping part. There are wiring grooves for the cable to pass through between the first end, the second end and the inner sidewall of the housing. A limiting part is used to radially limit the cable, and the limiting part is disposed inside the housing.

[0007] With the above structure, this utility model has the following advantages compared with the prior art: there are wiring grooves between the first end and the second end of the clamping part and the inner side wall of the shell, so that the cable can be arranged in any wiring groove, and the wiring is flexible; a limiting part is set to radially limit the cable, which facilitates the arrangement of the cable.

[0008] Preferably, the limiting part includes two limiting posts, and the cable is passed between the two limiting posts, which is simple in structure.

[0009] Preferably, it also includes a flexible support portion, with both ends of the flexible support portion fixed to the clamping portion. The inner wall of the flexible support portion and the surface of the clamping portion near the flexible support portion form a closed shape, through which the cable passes. When the flexible support portion is compressed, it indents towards the clamping portion to clamp the cable. The flexible support portion is provided on the clamping portion, and the flexible support portion and the clamping portion form a closed shape. The cable passes through the closed shape. In this way, compressing the flexible support portion can clamp the cable. Because it is a closed shape, the cable is not easy to detach from the flexible support portion, resulting in high reliability.

[0010] Preferably, the flexible support portion is provided with at least one crease that facilitates bending of the flexible support portion. The crease is distributed along the width direction of the flexible support portion, making it easier for the flexible support portion to be pressed onto the cable.

[0011] Preferably, it also includes a cable clamping part, on which the cable is clamped. The cable clamping part further limits and tightens the cable, resulting in high reliability.

[0012] A push-button switch, comprising a wiring structure as described in any of the preceding claims, further comprising: Housing; the wire clamping part is disposed inside the housing along the axial direction of the housing, and the first end and the second end of the wire clamping part are respectively provided with wiring grooves between them and the inner sidewall of the housing for the cable to pass through.

[0013] Preferably, the housing is provided with a wire clamping groove, and the wire clamping part is disposed in the wire clamping groove, which facilitates the placement of the wire clamping part inside the housing.

[0014] Preferably, the limiting part is located on the wiring groove, which does not take up space.

[0015] Preferably, the cable clamping part is located inside the housing, which facilitates clamping and limiting the cable located inside the housing.

[0016] Preferably, the housing includes: A first housing and a second housing; the clamping part is disposed inside the second housing, and the first housing is provided with a pressing part for pressing the flexible support part; When the first and second housings are joined together, the extrusion portion applies a force to the flexible support portion in the direction of the clamping portion.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Figure 1 This is a perspective view of a wiring structure according to this utility model. Figure 2 This is a perspective view of the push-button switch of this utility model without the first housing, as shown below. Figure 1 and 2 In the illustrated embodiment, a wiring structure includes a clamping portion 1 for connecting cables. The clamping portion 1 has a stationary contact piece. The clamping portion 1 is disposed within the housing 2 along the axial direction of the housing 1. The clamping portion 1 has a first end and a second end along the radial direction of the clamping portion 1. A wiring groove 3 is formed between the first end of the clamping portion 1 and the inner sidewall of the housing 2 near the first end of the clamping portion 1. A wiring groove 3 is also formed between the second end of the clamping portion 1 and the inner sidewall of the housing 2 near the second end of the clamping portion 1. This allows the cable to be arranged in one of the wiring grooves 3 according to the actual situation, providing flexible wiring. Specifically, the width of the wiring grooves 3 is uniform, making the wiring grooves 3 symmetrical about the axis of the housing 2. The housing 2 is an axisymmetric structure. The housing 1 can be aligned or deviated by 180°, which allows the cable to be assembled in the wiring groove 3, facilitating cable assembly. If there is only one wiring groove 3, the housing 1 must be aligned to assemble the cable, which is inconvenient.

[0023] In one embodiment, the clamping portion 1 is provided with a flexible support portion 110. Both ends of the flexible support portion 110 are fixed to the clamping portion 1. The inner wall of the flexible support portion 110 and the surface of the clamping portion 1 near the flexible support portion 110 form a closed shape, through which the cable passes. When the flexible support portion 10 is compressed, it indents towards the cable, adhering tightly to the cable and clamping it. Because it is a closed shape, the cable is less likely to detach from the flexible support portion 10, resulting in high reliability. Specifically, the flexible support portion 10 is made of polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyurethane, rubber, or other materials.

[0024] Furthermore, the flexible support portion 110 is arc-shaped with its opening facing the clamping portion 1, which is adapted to the shape of the cable, making it easy for the flexible support portion 110 to be pressed against the outer side of the cable.

[0025] Furthermore, the flexible support portion 110 is provided with at least one crease 111 to facilitate bending of the flexible support portion 110, and the crease 111 is distributed along the width direction of the flexible support portion 110. When the flexible support portion 110 is compressed, the flexible support portion 110 is concave along the direction of the crease 111, and the flexible support portion 110 is more easily compressed against the outer side of the cable. Specifically, there are three creases 111, which are located at both ends and the middle of the flexible support portion 110, respectively, making the flexible support portion 110 more easily deformed when subjected to pressure.

[0026] As one embodiment, it also includes a limiting part 410 for radially limiting the cable. The limiting part 410 is disposed inside the housing 2, restricting the cable within a certain range and providing radial limiting for the cable arrangement. Specifically, the limiting part 410 includes two limiting posts 411, and the cable passes between the two limiting posts 411. Further, one end of the limiting post 411 is fixed to the bottom surface of the housing 2, and the other end of the limiting post 411 is close to or abuts against the top surface of the housing 2. The cable is less likely to detach from the limiting part 410 in the area between the other end of the limiting post 411 and the top surface of the housing 2, resulting in high reliability. Specifically, the other end of the limiting post 411 is close to the top surface of the housing 2, and the distance between the other end of the limiting post 411 and the top surface of the housing 2 is less than the diameter of the cable.

[0027] As one embodiment, it also includes a cable clamping part 5, on which the cable is clamped, further limiting and tightening the cable, resulting in high reliability. Specifically, the cable clamping part 5 is provided with a cable clamping groove 510, on which the cable is clamped to achieve limiting and tightening.

[0028] Figure 3 This is a front sectional view of the push-button switch of this utility model, as shown below. Figure 3 In the illustrated embodiment, this utility model provides a push-button switch, including a housing 2. Two wire clamping portions 1 are provided inside the housing 2 to clamp cables. The wire clamping portions 1 are both located within the housing 2 along its axial direction. A wiring groove 3 for the cable to pass through is provided between the first end and the second end of each wire clamping portion 1 and the inner sidewall of the housing 2. Specifically, each wire clamping portion 1 corresponds to a stationary contact piece, and each wire clamping portion 1 corresponds to a cable. One cable is directly connected to its corresponding wire clamping portion 1, while the other cable needs to pass through the wiring groove 3 to connect to its corresponding wire clamping portion 1.

[0029] As one embodiment, the housing 2 is provided with a wire clamping groove 4, and the wire clamping part 1 is disposed in the wire clamping groove 4. Specifically, the way the wire clamping part 1 is fixed in the wire clamping groove 4 is similar to that of an anti-derailment switch in the prior art.

[0030] In one embodiment, the housing 2 includes a first housing 210 and a second housing 220. A clamping portion 1 is disposed within the second housing 220. The first housing 210 contains a pressing portion 211 for pressing the flexible support portion 110. The pressing portion 211 is located on the top surface of the first housing 210 corresponding to the flexible support portion 110. When the first housing 210 and the second housing 220 are joined together, the pressing portion 211 applies a force to the flexible support portion 110 in the direction of the clamping portion 1, causing the flexible support portion 110 to indent. Specifically, the pressing portion 211 can be columnar or rod-shaped.

[0031] In one embodiment, a limiting part 410 is provided in the wire clamping groove 4, and the number of limiting parts 410 is at least one. One end of the cable is clamped on the wire clamping part 1, and the other end of the cable passes through the limiting posts 411. Specifically, there are two limiting parts 410, and each limiting part 410 corresponds to one of the wire clamping parts 1, so that the two cables in the housing 2 can be limited.

[0032] As one embodiment, the wire-clamping part 5 is disposed inside the second housing 220, and the number of wire-clamping parts 5 is at least one. Specifically, there are two wire-clamping parts 5, and each wire-clamping part 5 corresponds to a wire-clamping part 1, so that the two cables inside the housing 2 can be clamped and limited.

[0033] Specifically, the locking groove 510 extends through both outer sides of the wire-clamping part 5 along the axial direction of the locking groove 510, and extends through the wire-clamping part 5 in the radial direction of the locking groove 510 toward the first housing 210, thus making the locking groove 510 an open groove, which facilitates the clamping of the cable within it. Specifically, the wire-clamping part 5 corresponds one-to-one with the wire-clamping part 1. The first cable passes through the closed pattern, the limiting part 410, the wire-clamping part 5, and the wiring groove 3 in sequence to extend out of the housing 2, and the second cable passes through the closed pattern, the limiting part 410, and the wire-clamping part 5 in sequence to extend out of the housing 2. The first cable connects to the stationary contact piece away from the outlet of the housing 2, and the second cable connects to the stationary contact piece near the outlet of the housing 2.

[0034] Specifically, the housing 2 has two wire clamping parts 1. The first cable is mounted on one of the wire clamping parts 1 through the wiring groove 3, and the second cable is mounted directly on the other wire clamping part 1. The first cable and the second cable are electrically connected to the stationary contact piece, respectively.

[0035] The principle of this utility model is that there are wiring grooves 3 between the first end and the second end of the clamping part 1 and the inner side wall of the housing 2, so that the first cable can be arranged in any of the wiring grooves 3, and the wiring is flexible; a limiting part 410 is set to radially limit the cable, which facilitates the arrangement of the cable.

[0036] Working principle: The first housing 210 and the second housing 220 are fixed together by bolts. When the first housing 210 and the second housing 220 are together, the pressing part 211 presses the middle of the flexible support part 110. The flexible support part 110 is recessed along the crease 111 towards the second cable. The flexible support part 110 presses on the second cable, achieving clamping of the second cable. The flexible support part 110 and the clamping part 1 form a closed shape. The second cable passes through the closed shape, and the second cable is not easy to detach from the flexible support part 110, resulting in high reliability.

[0037] Based on the above solutions, if any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
