Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and more specifically to a small wiring module. Background Technology

[0002] With the increasing miniaturization and integration of electronic devices and electrical systems, switchgear, as a key component for electrical connections, faces numerous challenges and demands for transformation. Existing switchgear wiring modules are often integrated into the switchgear itself, using screws for wire connections. This method is not only cumbersome, requiring tools, but also prone to loosening due to vibration and temperature changes over time, leading to unstable electrical connections and increasing the risk of equipment failure. Therefore, existing technologies have developed wiring modules that can be detached independently from the switchgear. Wires are directly connected to the wiring module, which can then be removed for maintenance, making it far more convenient than integrating wiring into the switchgear.

[0003] Currently, the internal structure of this wiring module is not stable enough in clamping the wires and needs improvement. In addition, the wiring module is divided into single-hole and double-hole types. The double-hole type means that two wires are connected to one wiring module. Depending on different needs, these two wires sometimes need to be plugged in and unplugged at the same time when connected to the wiring module, and sometimes they need to be plugged in and unplugged separately. The existing wiring module cannot adapt well to this need and needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a small wiring module with a reasonable internal structure design, stable wire clamping, and dual-hole connection. It can also control the clamping of two wires simultaneously or independently, making it convenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small wiring module, including a housing, on which a conductive cage is provided. The conductive cage has a frame-shaped structure and an opening. Two wiring cavities corresponding to the conductive cage are symmetrically arranged inside the housing. Each of the two wiring cavities is provided with a V-shaped wire clamping spring. Both ends of the wire clamping spring extend into the conductive cage through the opening and abut against the inner wall of the frame-shaped structure of the conductive cage. A wiring hole is provided on the housing. The wiring hole is located on one side of the opening of the conductive cage and at the position where the wire clamping spring and the inside of the conductive cage abut against each other. A movable pressing block is provided next to the wiring hole. One end of the pressing block extends into the two wiring cavities and abuts against the wire clamping spring, while the other end protrudes from the housing.

[0006] The present invention is further configured such that: a support column is provided in the wiring cavity, the bent part of the wire clamping spring cooperates with the support column, and a symmetrical narrowing structure is provided on the support column, and the wire clamping spring corresponds to the narrowing structure after bending and deformation.

[0007] The present invention is further configured such that: a protrusion is provided on the inner wall of the wiring hole of the conductive cage, and the protrusion abuts against the end of the clamping spring.

[0008] The present invention is further configured such that: a pushing part is provided at one end of the pressing block that abuts against the wire clamping spring, the pushing part is configured as an arc-shaped structure with protruding edges, the arc-shaped structure abuts against the wire clamping spring, and the edges are located on both sides of the wire clamping spring.

[0009] The present invention is further configured such that: one end of the pressing block extending into the two wiring cavities includes end a and end b, and end a and end b move synchronously and are integrally formed.

[0010] The present invention is further configured such that: one end of the pressing block extending into the two wiring cavities includes end a and end b, and end a and end b move independently or synchronously.

[0011] The present invention is further configured such that: a rotating component is provided inside the pressing block, and a rotating cavity for accommodating the rotating component is provided between the ends a and b; the rotating component has a locking position and an unlocking position; in the locking position, the ends a and b move synchronously; in the unlocking position, the ends a and b move independently.

[0012] The present invention is further configured such that: a linkage pin is provided on the rotating component, and an arc-shaped groove is provided at the positions corresponding to ends a and b of the rotating cavity; when the linkage pin is inserted into the arc-shaped groove, the rotating component is in a locked position; when the linkage pin is removed from the arc-shaped groove, the rotating component is in an unlocked position.

[0013] The present invention is further configured such that one end of the rotating component extends out of the pressing block, and a groove is provided on the end face for external tools to drive it.

[0014] The present invention is further configured such that: a limiting piece is provided on the rotating component, the limiting piece being used to prevent the rotating component from dislodging from the rotating cavity.

[0015] In summary, this utility model has the following beneficial effects:

[0016] Compared with the prior art, this utility model can stably clamp the wire by using the combination of the conductive cage and the clamping spring. The conductive cage is provided with a protrusion, which can limit the clamping spring and, when the wire is inserted, the downward pressure of the clamping spring and the protrusion can form a clamping force to prevent the wire from being misaligned, making the wire clamping more stable.

[0017] This utility model is equipped with a pressing block and a protruding shell on the outside of the pressing block, which makes it more convenient for manual operation and pressing. At the same time, the ends a and b of the pressing block can be integrally formed and move synchronously. In other embodiments, a split structure can be adopted, and synchronous and independent movement can be achieved by relying on the rotating component and the structure inside the rotating cavity. To meet different usage needs, two wires can be plugged in and unplugged at the same time or one wire can be plugged in and unplugged individually, making the usage flexible.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This embodiment discloses a small wiring module, such as Figure 1-6 As shown, the device includes a housing 1, on which a conductive cage 2 is mounted. The conductive cage 2 has a frame-shaped structure and an opening. Two wiring cavities 101 corresponding to the conductive cage 2 are symmetrically arranged inside the housing 1. (Refer to...) Figure 2Two wiring cavities 101 are located on opposite sides of the housing 1. The conductive cage 2 is relatively wide, allowing the two wiring cavities 101 to correspond precisely to it. Each wiring cavity 101 contains a V-shaped wire clamping spring 3. Both ends of the wire clamping spring 3 extend into the conductive cage 2 through its opening and rest against the inner wall of the frame structure of the conductive cage 2. A wiring hole 102 is provided on the housing 1, located on one side of the opening of the conductive cage 2 and at the point where the wire clamping spring 3 abuts against the interior of the conductive cage 2. (Refer to...) Figure 3 The wire 8 can enter through the wiring hole 102 and pass through the opening of the conductive cage 2, extending into the position between the wire clamping spring 3 and the conductive cage 2. (Refer to...) Figure 1-2 A movable pressing block 4 is provided next to the wiring hole 102. One end of the pressing block 4 extends into the two wiring cavities 101 and abuts against the wire clamping spring 3, while the other end protrudes from the housing 1. The protruding setting of the pressing block 4 from the housing 1 allows the operator to press it more easily. When pressed, the end abutting against the wire clamping spring 3 will push the clamping spring 3 to deform, thereby opening the gap between the wire clamping spring 3 and the inner wall of the conductive cage 2.

[0027] Furthermore, refer to Figure 2-3 A support post 6 is provided inside the wiring cavity 101. The bent part of the wire clamping spring 3 cooperates with the support post 6. A symmetrical narrowing structure 601 is provided on the support post 6. Figure 3 When the wire clamping spring 3 bends and deforms, it corresponds to the narrowing structure 601. The narrowing structure 601 supports the bent and deformed part of the wire clamping spring 3, preventing excessive bending due to excessive pushing of the pushing block 4 or thick wires, which would lead to a decrease in elasticity. Compared with the traditional cylindrical structure, the narrowing structure 601 provides better support at the bend of the wire clamping spring 3, making it less prone to excessive bending and effectively extending its service life.

[0028] Furthermore, refer to Figure 3 The conductive cage 2 has a protrusion 201 on the inner wall of the wiring hole 102, which abuts against the end of the wire clamping spring 3. The protrusion 201 serves two purposes: firstly, it limits the position of the wire clamping spring 3; secondly, when the wire 8 is inserted, if the wire clamping spring 3 provides a downward clamping force, the protruding part 201 is positioned on the opposite side, providing a counterforce, thus generating a force similar to... Figure 3 The misaligned clamping force, indicated by the dashed arrow, provides a more stable and secure grip on the wire 8. Compared to the traditional flat bottom structure, which only provides upward reaction force and friction but lacks the oblique force of the protrusion 201, the clamping force is generally weak, making it easy for the wire to come out. The clamping force of this embodiment is significantly better.

[0029] Furthermore, refer to Figure 4 The pressing block 4 is provided with a pushing part 7 at the end that abuts against the wire clamping spring 3. The pushing part 7 is set with an arc-shaped structure and protruding edges. The arc-shaped structure abuts against the wire clamping spring 3, and the edges are located on both sides of the wire clamping spring 3. The arc-shaped structure can push the wire clamping spring 3 better, and when the wire clamping spring 3 deforms and changes its abutting position, the arc-shaped structure can adapt well and will not damage the wire clamping spring 3. The edges can constrain and clamp the spring 3 to prevent it from shifting laterally.

[0030] Furthermore, based on the above embodiments, there are two embodiments depending on the different structures of the push block.

[0031] Example 1: As Figure 4 The pressing block 4 extends into one end of the two wiring cavities, including end a401 and end b402. Ends a401 and b402 move synchronously and are integrally formed. This structure is simple and reliable. Furthermore, the wiring module in this embodiment has a dual-hole structure, with two wiring holes on the housing 1, each corresponding to one of the two wiring cavities. The integrally formed pressing block 4 can simultaneously control the movement of ends a401 and b402, thus simultaneously controlling the clamping and releasing of the wires within the dual holes.

[0032] Example 2: Depending on the requirements, the wires within the dual holes may need to be disassembled and repaired individually, in addition to being simultaneously clamped and released. Therefore, ends a401 and b402 can move independently or synchronously. For details, refer to... Figure 5-6 The pressing block 4 is equipped with a rotating component 403, and a rotating cavity 5 is provided between ends a and b to accommodate the rotating component 403. The rotating component 403 has a locking position and an unlocking position. In the locking position, ends a and b move synchronously, and in the unlocking position, ends a and b move independently. Thus, by rotating the rotating component 403, the linkage relationship between ends a and b can be switched, which can be adjusted according to actual needs, making it more convenient.

[0033] like Figure 6 The rotating component 403 is equipped with a linkage pin 404. Arc-shaped grooves 501 are provided at the corresponding positions of ends a401 and b402 in the rotating cavity 5. When the linkage pin 404 is engaged in the arc-shaped groove 501, the rotating component is in a locked position; when the linkage pin 404 is removed from the arc-shaped groove 501, the rotating component is in an unlocked position. Specifically, the linkage pins 401 are symmetrically arranged. When the rotating component 403 rotates clockwise as shown in the figure, the upper linkage pin engages at end b, and the lower linkage pin engages at end a (not shown in the figure). Thus, ends a and b are linked together by the rotating component 403 and the linkage pins 404, allowing them to move synchronously. When independent movement is required, the rotating component 403 is rotated to the position shown in the figure. Figure 6At this position, the linkage pin 404 is exactly in the gap between end a and end b, and end a and end b can be pushed forward independently to assemble and disassemble the wires in the individual wiring holes.

[0034] Furthermore, one end of the rotating component 403 extends beyond the pressing block 4, and a groove for driving external tools is provided on its end face. (See reference...) Figure 6 The groove shown in the attached image is a flathead type, which is convenient for rotation and adjustment using a flathead screwdriver. Of course, other groove types such as Torx or Phillips head can also be selected.

[0035] Further, refer to Figure 6 A limiting piece 405 is provided on the rotating component 403 to prevent the rotating component from dislodging from the rotating cavity 5. Specifically, the limiting piece 405 is located at the innermost end, and there is space between it and the end face of the arc-shaped groove 501 for the pushing block 4 to push forward (this space is greater than or equal to the stroke of the forward pushing of the clamping spring). In this way, when pushing end a or end b forward individually, the limiting piece will not interfere with the independent movement of end a and end b. When the rotating component 403 dislodles outward, the limiting piece 405 can prevent it from dislodging. Generally, end a and end b are linked together by the rotating component 403. Only when necessary, the rotating component 403 is rotated to the unlocking position, so that end a and end b can move independently. After the disassembly and assembly of the corresponding single-hole wire is completed, the rotating component 403 can be rotated back to the locking position.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
