Description

Technical Field

[0001] This utility model relates to the field of conductive connection technology, and more specifically to a connector for interconnecting electrical wires. Background Technology

[0002] Efficient and reliable wire connections are crucial for ensuring stable circuit operation. Traditional wire interconnection methods include screw crimping or insulation piercing. Screw crimping requires stripping the wire ends and manually adjusting the screw pressure, which is not only complex but also demands a high level of skill and experience from the operator. Excessive screw pressure can damage the wire, while insufficient pressure can cause it to loosen. Furthermore, screw crimping has extremely limited compatibility with wire diameters. Insulation piercing eliminates the need for wire stripping, but it places high demands on the thickness and material of the wire insulation, and prolonged use may lead to poor wire contact due to stress relaxation. In addition, traditional wire interconnection methods lack guiding design, making wires prone to misalignment during interconnection and affecting wiring efficiency.

[0003] Existing technologies include methods that use elastic clamps to hold the stripped ends of wires to achieve wire interconnection. Compared to traditional wire interconnection methods, this reduces operational complexity to some extent, but several problems remain: First, the clamping force provided by the elastic clamps depends on the elasticity of the material, which is prone to fatigue with long-term use; second, the elastic clamps are not ideally adaptable to the wire diameter, making it difficult to clamp thinner wires and thicker wires; third, there is a lack of multi-directional anti-loosening mechanisms, which leads to decreased reliability, especially in scenarios involving vibration or temperature changes. Utility Model Content

[0004] This utility model provides a wiring device for electrical maintenance in order to avoid the shortcomings of the prior art.

[0005] The present invention adopts the following technical solution to solve the technical problem: a wiring device for electrical maintenance, including a housing, and is provided with a wiring block, a limiting plate and a rotating column; The rotating column has a cylindrical structure, is installed through the terminal block with its axis upright, and is rotatably connected to the terminal block; An elliptical limiting groove is formed on the outer periphery of the rotating column on the wiring block, and wire grooves extending through the front and rear ends of the limiting groove to the front and rear ends of the wiring block are formed respectively; an elliptical arc-shaped plate-like limiting plate is provided inside the limiting groove. A through slot is radially opened on the rotating column, communicating with a pair of wire slots, and a wiring area is formed between the rotating column and the limiting plate, with the gap size decreasing from both ends to the middle of the wiring block. The outer casing is fitted onto the outside of the wiring block, and at least one end of the rotating column extends out of the outer casing.

[0006] Furthermore, the inner surface of the limiting plate is densely covered with limiting teeth.

[0007] Furthermore, the outer surface of the rotating column is densely covered with tooth structures corresponding to the shape of the limiting teeth.

[0008] Furthermore, the groove has a trapezoidal groove structure with a width decreasing from the end to the middle of the wiring block.

[0009] Furthermore, the end shape and dimensions of the groove facing the through groove correspond to the end shape and dimensions of the through groove.

[0010] Furthermore, one end of the rotating column extending outside the outer casing is covered and fixed with a knob made of insulating material.

[0011] Furthermore, the cross-section of the limiting groove is co-centered with the cross-section of the rotating column.

[0012] This utility model provides a connector for electrical maintenance, which has the following advantages: 1. This utility model rotates a rotating column, causing the wire passing through the slot to rotate. The wire follows the rotation of the slot and is clamped into the wiring area formed between the rotating column and the limiting plate, and is pressed and fixed. The wires are interconnected through the rotating column, which greatly reduces the difficulty of wiring and the complexity of operation, improves wiring efficiency, and almost never loses the limiting function due to practical fatigue, thus having high reliability.

[0013] 2. The limiting teeth densely arranged on the inner side of the limiting plate of this utility model can embed into the insulation layer of the wire when the wire is pressed and locked between the rotating column and the limiting plate, providing multi-directional biting force to the wire, realizing the wire anti-loosening limiting, and further improving the reliability of the connector operation.

[0014] 3. The toothed structure on the outer side of the rotating column of this utility model can reduce or eliminate the relative sliding between the limiting column and the wire, and can embed the insulation layer of the wire when the wire is pressed between the rotating column and the limiting plate. Together with the limiting teeth, it provides multi-directional biting force to the wire, further improving the stability and reliability of the wiring. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] A type of electrical maintenance connector, such as Figures 1-3 As shown, its structural relationship is as follows: it includes a shell 1, and is provided with a wiring block 3, a limiting plate 4 and a rotating column 5; The rotating column 5 has a cylindrical structure and is installed through the terminal block 3 with its axis upright. It is rotatably connected to the terminal block 3 with its own axis as the pivot. An elliptical limiting groove 32 is formed on the outer periphery of the rotating column 5 on the wiring block 3, and wire grooves 31 are formed from the front end and the rear end of the limiting groove 32 to the front end and the rear end of the wiring block 3, respectively; an elliptical arc-shaped plate-like limiting plate 4 is covered inside the limiting groove 32. A through slot is radially opened on the rotating column 5, which communicates with a pair of wire grooves 31. A wiring area is formed between the rotating column 5 and the limiting plate 4, with the gap size decreasing from both ends to the middle of the wiring block 3. The outer casing 1 is fitted onto the outside of the wiring block 3, and at least one end of the rotating column 5 extends out of the outer casing 1.

[0019] Since the wires need to be interconnected via the rotating post 5, the portion of the rotating post 5 that contacts the conductive section of the wire end exposed outside the insulation should be made of conductive material.

[0020] Preferably, the inner surface of the limiting plate 4 is densely provided with limiting teeth 41. The limiting teeth 41 can be embedded in the insulation layer of the wire after the wire is pressed between the rotating column 5 and the limiting plate 4, providing multi-directional biting force to the wire and realizing the wire's anti-loosening limiting.

[0021] Preferably, the outer surface of the rotating post 5 is densely covered with tooth structures corresponding to the shape of the limiting teeth 41, so that the limiting post 5 can more easily bring the wire into the wiring area and press it, reduce or eliminate the relative sliding between the limiting post 5 and the wire, and can embed the insulation layer of the wire when the wire is pressed between the rotating post 5 and the limiting plate 4, together with the limiting teeth 41 to provide multi-directional biting force to the wire, further improving the stability and reliability of the wiring.

[0022] Preferably, the wire groove 31 has a trapezoidal groove structure with a width decreasing from the end to the middle of the connector block 3. The trapezoidal groove structure of the wire groove 31 can realize the guidance and centering of the wire so that the wire can pass smoothly through the wire groove 31 and the through groove.

[0023] Preferably, the end shape and dimensions of the groove 31 facing the through groove correspond to the end shape and dimensions of the through groove.

[0024] Preferably, the end of the rotating column 5 extending out of the outer casing 1 is covered and fixed with a knob 2 made of insulating material. When in use, the rotating column 5 can be easily rotated by applying force to the knob 2.

[0025] Preferably, the cross-section of the limiting groove 32 is co-centered with the cross-section of the rotating column 5.

[0026] Interconnecting wires using the above-described connectors includes the following process: The first step is to strip the insulation from the ends of the wires to be interconnected, exposing the conductive sections at the ends of the wires; the length of the stripped conductive sections is preferably 5 to 10 mm.

[0027] The second step is to insert the wires that need to be interconnected through the wire groove 31 at one end of the connector block 3, so that the wires pass through the wire groove 31 on the connector block 3 and the through groove on the rotating column 5.

[0028] The third step is to apply force to the knob 2 to drive the rotating column 5 to rotate relative to the limiting plate 4. The wire in the through groove follows the rotation of the through groove, so that the wire starts to be inserted into the wiring area formed between the rotating column 5 and the limiting plate 4 from the part located at the junction of the through groove and the wire groove 31. As the gap of the wiring area shrinks, it is gradually pressed between the rotating column 5 and the limiting plate 4. At the same time, it should be ensured that after the wire is pressed between the rotating column 5 and the limiting plate 4, the conductive part of the wire can maintain good contact with the rotating column 5. As the wire is gradually pressed between the rotating column 5 and the limiting plate 4, the limiting teeth 41 and the tooth structure are also gradually embedded into the insulation layer of the wire, thereby achieving the anti-loosening and limiting of the wire.
