Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a quick-connect wire connector. Background Technology

[0002] In industrial production, construction, and daily life, wire connection is an unavoidable and very common operation. There are many traditional wire connection methods, but they all have some inherent defects. Early common connection methods include manual twisting and wrapping with insulating tape. This method depends on the worker's skill level, the connection quality is unstable, the insulation protection is insufficient, and it is easily affected by environmental factors and ages and fails, thus causing short circuits or leakage risks.

[0003] With technological advancements, methods such as screw-on terminals and welding connections have emerged. While screw-on terminals offer a more reliable physical connection, operating screws in confined spaces is often time-consuming and inconvenient, especially when batch connections are required, resulting in low efficiency. Furthermore, the tightness of the screw directly affects contact resistance; over-tightening can damage the wires, while under-tightening leads to loose connections and safety hazards. Welding connections provide stable connections with low resistance, but welding requires specialized tools and skills, involves complex processes, generates high temperatures, and poses safety risks. After connection, the welded joints typically require additional insulation, further increasing operation time and cost. Moreover, welded connections are usually permanent, making disassembly and repair extremely inconvenient if problems arise. In addition, regardless of the connection method, connected wires are often subjected to external mechanical stresses such as vibration, tension, or bending in practical applications. These mechanical stresses directly act on the connection points, leading to poor contact within the wires or damage to the insulation layer, thereby reducing the electrical performance and mechanical strength of the connection. Over time, this can result in loosening, open circuits, or short circuits at the connection points, seriously affecting the normal operation of equipment and personal and property safety, and reducing the overall system reliability.

[0004] Therefore, this utility model proposes a quick-connect wire connector to overcome the shortcomings of the prior art. Utility Model Content

[0018] 2.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 5 This utility model provides a quick-connect wire connector, which aims to solve the problems of complex operation, insufficient connection stability, and easy loosening of wires after connection in the prior art.

[0029] Please refer to Figure 1 and Figure 2 The quick-connect wire connector includes a wire body 1, a wiring mechanism 2, and a fixing mechanism 3. The wire body 1 is the wire to be connected. The wiring mechanism 2 is the core component of the wire connector that enables quick wire connection. The fixing mechanism 3 is used to further stabilize the wire after the connection is completed, ensuring the long-term reliability of the connection. The wiring mechanism 2 and the fixing mechanism 3 work together to form the overall structure of the quick-connect wire connector.

[0030] The wiring mechanism 2 includes a housing 201, a rotating ring 202, a connecting seat 203, a rubber screw 204, an air expansion ring 205, a limiting hole 206, a limiting rod 207, a lever 208, a return spring 209, and a fixing ring 210. The housing 201 is the main structure of the wiring mechanism 2, serving as the external frame and support platform for the entire wiring device. An air expansion ring 205 is provided on the inner wall of the housing 201, and a rubber screw 204 is slidably connected to the inner wall of the air expansion ring 205. The outer wall of the rubber screw 204... A retaining ring 210 is threaded onto the wall. The outer wall of the retaining ring 210 is fixedly connected to the rotating ring 202. The rotating ring 202 and the outer shell 201 are connected by a rotational fit. A connecting seat 203 is fixedly connected to the outer wall of the outer shell 201. A limiting hole 206 is opened on the outer wall of the rotating ring 202. A limiting rod 207 is slidably connected to the inner wall of the connecting seat 203. A lever 208 is connected to the left end of the limiting rod 207. A return spring 209 is fixedly connected to the outer wall of the lever 208.

[0031] The fixing mechanism 3 includes a fixing seat 301, a connecting frame 302, a locking groove 303, a locking block 304, a connecting rod 305, a clamping plate 306, a friction groove 307, a connecting hole 308, and a fixing rod 309. The fixing seat 301 is the external structure of the fixing mechanism 3 and is used to connect with the wiring mechanism 2. Multiple sets of locking grooves 303 are opened at both ends of the outer shell 201. The locking block 304 is fixedly connected to the fixing seat 301. The locking block 304 is connected to the locking groove 303 on the outer shell 201 by locking. Two sets of connecting rods 305 are slidably connected to the inner wall of the fixing seat 301. A clamping plate 306 is fixedly connected to the adjacent end of the connecting rod 305. The connecting frame 302 is connected at a height at the far end of the connecting rod 305. A friction groove 307 is opened on the adjacent side of the clamping plate 306. Multiple sets of connecting holes 308 are opened on the top of the connecting frame 302. The fixing rod 309 is slidably connected to the inner wall of the connecting hole 308.

[0032] Please refer to Figures 2 to 4 The air expansion ring 205, as a key component for initial clamping, is located on the inner wall of the outer shell 201. A rubber screw 204 is slidably connected to the inner wall of the air expansion ring 205. The outer wall of the rubber screw 204 is connected to the fixing ring 210 by a threaded connection. The outer wall of the fixing ring 210 is fixedly connected to the rotating ring 202. This structure allows gas to be injected into the air expansion ring 205 when the rubber screw 204 is pressed down, causing the air expansion ring 205 to expand due to the increased air pressure, thereby clamping and fixing the wire body 1 inserted from both ends of the outer shell 201. At the same time, the self-locking of the rubber screw 204 and the fixing ring 210 stabilizes the covering effect of the wire body 1.

[0033] The rotating ring 202 is rotatably connected to the outer shell 201. A limiting hole 206 for positioning and locking is provided on the outer wall of the rotating ring 202. A connecting seat 203 is fixedly connected to the outer wall of the outer shell 201. The connecting seat 203 provides a mounting base and sliding guide for the limiting rod 207. The limiting rod 207 is slidably connected to the inner wall of the connecting seat 203. A lever 208 is connected to the left end of the limiting rod 207. A return spring 209 is fixedly connected to the outer wall of the lever 208. In the assembled state, the elastic force of the return spring 209 acts on the lever 208, thereby driving the end of the limiting rod 207 to engage in the limiting hole 206 of the rotating ring 202. This locking structure, which is composed of the return spring 209, lever 208, limiting rod 207 and limiting hole 206, ensures that the rotating ring 202 can be reliably locked after rotating to the predetermined position, thereby preventing the connection from loosening due to the reverse torque generated by the torsion of the wire body 1, and improving the stability of the connection.

[0034] For the rotation operation of the rotating ring 202, the paddle 208 needs to be squeezed towards the return spring 209 first. After the paddle 208 is subjected to force, it drives the limiting rod 207 to overcome the elastic force of the return spring 209 and move, so that the end of the limiting rod 207 is disengaged from the limiting hole 206, releasing the lock on the rotating ring 202. At this time, the rotating ring 202 can be rotated freely. The rotating ring 202 drives the air expansion ring 205 and the clamped wire body 1 to rotate synchronously through the fixing ring 210 and the rubber screw 204, thereby realizing the twisting and winding of the wire body 1.

[0035] In a preferred embodiment, the left end of the paddle 208 is connected to a limiting rod 207. The left end of the limiting rod 207 is fixedly connected to the paddle 208. When the paddle 208 is pressed, it will drive the limiting rod 207 to move, thereby allowing the limiting rod 207 to slide within the connecting seat 203, so as to achieve engagement or disengagement with the limiting hole 206.

[0036] In another preferred embodiment, the outer wall of the return spring 209 is fixedly connected to the outer wall of the paddle 208. One end of the return spring 209 is fixedly connected to the paddle 208, and the other end abuts against the inner wall of the connecting seat 203. When the paddle 208 is squeezed and displaced, the return spring 209 is compressed and generates a reaction force. This force is used to drive the limiting rod 207 to move in the opposite direction after the paddle 208 loses the external squeezing force, so that the end of the rod is inserted into the limiting hole 206 of the rotating ring 202, thereby locking the rotating ring 202 in a fixed position and preventing the rotating ring 202 from rotating unexpectedly when there is no human operation.

[0037] In a preferred embodiment, when connecting the wires, the insulation layer of the two wire bodies 1 is first stripped off. Then, the wire bodies 1 are inserted into the middle position from the front and rear ends of the outer casing 201. By pressing down on the rubber screw 204, the piston of the rubber screw 204 can be moved downward, compressing the air and thus filling the air expansion ring 205 with gas. The air expansion ring 205 expands outward due to the increase in internal air pressure, tightly clamping the inserted wire body 1, thus achieving the initial fixation and covering of the wire body 1.

[0038] In a preferred embodiment, the far end of the connecting rod 305 in the fixing mechanism 3 is connected to the bottom of the connecting frame 302. The top of the connecting frame 302 is a pressing surface. By pressing the connecting frame 302 inward, the connecting frame 302 drives the two sets of connecting rods 305 connected to it to slide towards the center of the fixing seat 301. The movement of the connecting rod 305 in turn drives the clamping plate 306 fixedly connected to it to move closer to the center, thereby squeezing and fixing the internal wire body 1 between the clamping plates 306.

[0039] As a preferred embodiment, friction grooves 307 are provided on each adjacent side of the clamping plate 306. The friction grooves 307 have a sawtooth or wavy structure, which are used to increase the friction between the clamping plate 306 and the insulation layer of the conductor body 1 when the clamping plate 306 squeezes and fixes the conductor body 1. Through the friction grooves 307, the stability of the clamping is effectively improved without damaging the conductor body 1, preventing the conductor body 1 from sliding or loosening after clamping, and strengthening the fixing effect.

[0040] In a preferred embodiment, after the clamping plate 306 clamps and fixes the conductor body 1, it is necessary to lock the clamping state to prevent loosening. The top of the connecting frame 302 is provided with two sets of connecting holes 308. When the two sets of connecting holes 308 overlap due to the pressing and moving of the connecting frame 302, the fixing rod 309 is inserted into the overlapping connecting holes 308. After the fixing rod 309 passes through the two sets of connecting holes 308, it can restrict the relative movement of the connecting frame 302, thereby fixing the position of the connecting frame 302 and the clamping plate 306, preventing the clamping plate 306 from loosening its clamping of the conductor body 1 due to accidental contact or stress on the conductor body 1, and ensuring the long-term stability of the connection.

[0041] In a preferred embodiment, multiple sets of engaging slots 303 are provided at both ends of the housing 201. The engaging slots 303 are groove structures used to cooperate with engaging blocks 304 on the fixing base 301. The fixing base 301 is fixedly connected to the engaging blocks 304, which are protruding structures that match the shape and size of the engaging slots 303. After the wiring is completed, the wire body 1 is passed through the inside of the fixing base 301, and then the engaging blocks 304 on the fixing base 301 are pushed into the engaging slots 303 on the housing 201. The assembly of the fixing base 301 and the housing 201 is completed by engaging. This connection method makes it easy to install and remove the fixing base 301, and also provides a preliminary fixing effect on the outside of the connector.

[0042] Working principle: When quick wiring of the conductor body 1 is required, firstly, manually strip the insulation layer of the two conductor bodies 1 at the connection points. Then, insert the two sets of conductor bodies 1 into the middle position inside the outer casing 201 from the front and rear ends respectively. By pressing down on the rubber screw 204, gas is injected into the air expansion ring 205, increasing the air pressure in the air expansion ring 205 and clamping and fixing the conductor body 1, thereby covering the two sets of conductors to be connected in the middle, achieving the initial connection effect. Due to the rubber screw 204... The outer wall of the casing is threaded with a retaining ring 210, and the outer wall of the retaining ring 210 is fixedly connected with a rotating ring 202. Therefore, when the rubber screw 204 is pressed down to make the air expansion ring 205 wrap around the conductor body 1, the rubber screw 204 and the retaining ring 210 are threaded together to achieve self-locking, thereby stabilizing the wrapping effect on the conductor body 1. Since the rotating ring 202 is rotatably connected to the outer casing 201, rotating the rotating ring 202 drives the internal air expansion ring 205 and the conductor body 1 to rotate, causing the internal conductor body 1 to twist. The wires are better wound together, thus strengthening the connection effect of the main body 1. Since the outer wall of the rotating ring 202 has a limit hole 206, the outer wall of the outer shell 201 is fixedly connected to the connecting seat 203, and the inner wall of the connecting seat 203 is slidably connected to the limit rod 207. The left end of the limit rod 207 is connected to the lever 208, and the outer wall of the lever 208 is fixedly connected to the return spring 209. Therefore, before rotating the rotating ring 202, the lever 208 is first pressed towards the return spring 209, and the lever 208 drives the limit rod 207 to move. This prevents the limiting rod 207 from restricting the rotation of the rotating ring 202. After the rotating ring 202 has finished rotating, the pressure on the paddle 208 is released. Under the reaction force of the return spring 209, the limiting rod 207 is displaced in the opposite direction and thus gets stuck into the inner wall of the limiting hole 206, thereby fixing the position of the rotating ring 202 at this time and preventing the loosening of the internal wire body 1 by twisting. This achieves the effect of stable connection. Finally, the wiring mechanism 2 completes the quick connection of the wire body 1, which saves operation time and reduces the operation threshold.

[0043] After the wiring of the main body 1 is completed, in order to prevent the main body 1 from loosening inside the outer casing 201 and weakening the connection effect, the main body 1 can be fixed by the fixing mechanism 3, thereby reducing the shaking of the main body 1. Since multiple sets of engaging slots 303 are opened at both ends of the outer casing 201, and engaging blocks 304 are engaged on the inner wall of the engaging slots 303, and fixing seats 301 are fixedly connected to the outer wall of the engaging blocks 304, after the wiring is completed, the inside of the fixing seat 301 is passed through the main body 1, so that the engaging blocks 304 on the fixing seat 301 are engaged into the engaging slots 303 on the outer casing 201, thereby completing the assembly of the fixing seat 301 and the outer casing 201, thus completing the preliminary fixing effect before fixing. Since two sets of connecting rods 305 are slidably connected to the inner wall of the fixing seat 301, and clamps 306 are fixedly connected to adjacent ends of the connecting rods 305, and connecting brackets 3 are connected at a height of the far end of the connecting rods 305. 02. Therefore, by pressing the connecting frame 302 inward, the clamping plate 306 is moved closer to the center, thereby squeezing and fixing the internal conductor body 1. Since friction grooves 307 are provided on both adjacent sides of the clamping plate 306, the friction between the clamping plate 306 and the conductor body 1 is increased by the friction grooves 307 when squeezing the conductor body 1, thus strengthening the fixing effect. Since multiple sets of connecting holes 308 are provided on the top of the connecting frame 302, and the inner wall of the connecting hole 308 is slidably connected to the fixing rod 309, after the clamping plate 306 has finished clamping and fixing the conductor body 1, the fixing rod 309 is inserted into the connecting holes 308 of the two sets of connecting frames 302, thereby fixing the position of the connecting frame 302 and the clamping plate 306, preventing the clamping plate 306 from loosening the conductor body 1, and playing a role in strengthening the connection. Finally, the fixing mechanism 3 fixes the conductor body 1, improving the stability of the wiring.
