Description

Technical Field

[0001] This utility model relates to the field of automotive connection technology, specifically a multi-wire detachable automotive control connection cable. Background Technology

[0002] Automotive control wiring harnesses, also known as high-voltage wiring harnesses, are important components of the electrical system in new energy vehicles. They are separate wiring harnesses that bundle multiple cables together, allowing one port to be connected to multiple different connection ports simultaneously.

[0003] The existing connection cable has a simple structure, which only connects one end of multiple cables to the connector. The cable portion is exposed on the outside. During use, the cables are easy to get tangled together and are easily scratched by the edges of metal parts inside the car, affecting their use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing cables, such as easy tangling and easy damage from metal parts, and to provide a multi-wire detachable automotive control connection cable.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-wire detachable automotive control connection wire, comprising a wire harness, wherein the wire harness is composed of a plurality of cables, one end of the wire harness is provided with a first connector, and the connector is fixedly connected to the plurality of cables, the other end of the plurality of cables is fixedly connected to a second connector, a sleeve is provided on the outside of the wire harness, one end of the sleeve is fixedly connected to the first connector, and the other end is fixedly connected to a fixing mechanism.

[0006] As described above, the first connector has a first groove on both the left and right sides, and a movable plate is provided in each of the two first grooves. Several barbs with triangular cross sections are fixedly connected to the outside of the movable plate.

[0007] As described above, a movable block is provided in the first groove. The movable block is L-shaped, and the opposite sides of the movable plate and the movable block are both inclined surfaces and fit together. A spring is fixedly connected between the movable block and the first groove.

[0008] As described above, the sleeve includes an inner tube and an outer tube. The inner tube is sleeved on the outside of the wire harness, and the outer tube is sleeved on the outside of the inner tube. The outer tube is a plastic corrugated pipe, the inner tube is a rubber hose, and a fireproof cloth layer is filled between the inner tube and the outer tube.

[0009] The aforementioned fixing mechanism includes a frame, which is fixedly connected to the end of the sleeve. The frame contains several clamping blocks, and several semi-circular arc-shaped grooves are opened on opposite sides of two adjacent clamping blocks, through which the cable passes.

[0010] As described above, a second groove is provided on the inner wall of the frame, and two symmetrically arranged U-shaped plates are provided in the groove, with the clamping block located between the two U-shaped plates.

[0011] As described above, the frame is provided with threaded holes, and screws are threaded into the threaded holes. The screws are movably connected to the U-shaped plate, and elastic rubber pads are fixedly connected between two adjacent clamping blocks and between the clamping blocks and the U-shaped plate.

[0012] Compared with existing technologies, this multi-wire split-type automotive control connection cable has the following advantages:

[0013] I. This utility model uses a sleeve to cover the outside of the wire harness, thereby constraining the wire harness and keeping it neat during connection, preventing the wire harness from getting tangled with each other or with other connecting wires.

[0014] Second, this utility model provides protection for the wire harness by setting a sleeve to prevent the wire harness from being scratched by the edges of metal parts inside the equipment. The sleeve is also equipped with a fireproof cloth layer to improve the fire resistance and flame retardancy of the wire harness. The movable end of the sleeve is equipped with a rubber connection to improve the sealing performance and prevent water ingress.

[0015] Third, by setting up movable blocks and barbs, this utility model increases the surface roughness of the first connector, thereby increasing the friction between the first connector and the plug port, resisting the tendency of the first connector to move outward relative to the plug port, and thus preventing the first connector from falling off due to vehicle vibration.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a multi-wire detachable automotive control connection wire, including a wire harness 1, which is composed of a plurality of cables 101. One end of the wire harness 1 is provided with a first connector 102, and the connector is fixedly connected to the plurality of cables 101. The other end of the plurality of cables 101 is fixedly connected to a second connector 103. A sleeve 2 is provided on the outside of the wire harness 1. One end of the sleeve 2 is fixedly connected to the first connector 102, and the other end is fixedly connected to a fixing mechanism 3.

[0025] According to the overall structure of the device, the first connector 102 and the second connector 103 are respectively plugged into the corresponding plug-in ports to connect the control system. The sleeve 2 protects the wire harness 1 to prevent the cables 101 from getting tangled and to prevent the cables 101 from being cut. The end of the sleeve 2 can move on the wire harness 1 to accommodate different separation points of the cables 101, which facilitates the connection of the cables 101. A fixing mechanism 3 is set at the movable end of the sleeve 2 for fixing.

[0026] like Figure 2 , 4 As shown, the first connector 102 has a first groove on both the left and right sides. A movable plate 4 is provided in each of the two first grooves. Several barbs 6 with triangular cross sections are fixedly connected to the outside of the movable plate 4. Slide grooves are provided on the upper and lower sides of the movable plate 4. Limiting plates are provided at the top and bottom of the first grooves, and the limiting plates are inserted into the slide grooves.

[0027] The barbs 6 increase the friction between the first connector 102 and the plug-in port, strengthening the connection between the first connector 102 and the plug-in port. At the same time, the movable plate 4 can move within the first groove, allowing the barbs 6 to separate from the plug-in port, making it easier to pull out the first connector 102.

[0028] like Figure 4 As shown, a movable block 5 is provided in the first groove. The movable block 5 is L-shaped. The opposite sides of the movable plate 4 and the movable block 5 are both inclined surfaces and fit together. A spring 7 is fixedly connected between the movable block 5 and the first groove.

[0029] The spring force of the spring 7 pushes the movable block 5 to fit against the movable plate 4, so that the movable block 5 is inserted into the inner side of the movable plate 4 and abuts against the movable plate 4, thereby causing the barb 6 to be stuck inside the insertion port. The side of the movable block 5 opposite to the movable plate 4 is inclined, which makes it easy for the movable block 5 to be inserted into the inner side of the movable plate 4 or away from the movable plate 4. This controls the fixing and loosening of the movable plate 4. When the movable plate 4 is fixed, it improves the stability of the insertion. When it is loose, it is easy to pull out the first connector 102.

[0030] like Figure 5 As shown, the sleeve 2 includes an inner tube 202 and an outer tube 201. The inner tube 202 is sleeved on the outside of the wire harness 1, and the outer tube 201 is sleeved on the outside of the inner tube 202. The outer tube 201 is a plastic corrugated pipe, and the inner tube 202 is a rubber hose. A fireproof cloth layer 203 is filled between the inner tube 202 and the outer tube 201.

[0031] The inner tube 202 and the outer tube 201 provide multi-layer protection for the wire harness 1. The corrugated tube and rubber hose facilitate the bending of the wire harness 1 and the position adjustment of the movable end of the sleeve 2 is also convenient. The fireproof cloth layer 203 makes the sleeve 2 uniformly fireproof and flame-retardant, thereby improving the high temperature resistance of the wire harness 1.

[0032] like Figure 3 As shown, the fixing mechanism 3 includes a frame 301, which is fixedly connected to the end of the sleeve 2. The frame 301 has several clamping blocks 302 inside, and several semi-circular arc grooves are opened on opposite sides of two adjacent clamping blocks 302. The cable 101 passes through the arc grooves. A second groove is opened on the inner wall of the frame 301, and two symmetrically arranged U-shaped plates 303 are provided in the groove. The clamping blocks 302 are located between the two U-shaped plates 303. The frame 301 has a threaded hole, and a screw 305 is threaded into the threaded hole. The screw 305 is movably connected to the U-shaped plate 303. Elastic rubber pads 304 are fixedly connected between two adjacent clamping blocks 302 and between the clamping blocks 302 and the U-shaped plates 303.

[0033] The cable 101 is restrained by the frame 301, allowing it to pass through the arc-shaped groove between the clamping blocks 302. The clamping blocks 302 clamp and fix the cable 101. The clamping blocks 302 are connected by rubber pads 304, which facilitates the movement of the clamping blocks 302. The rubber pads 304 can seal the gaps between the clamping blocks 302 and the U-shaped plates 303 to prevent water ingress. By turning the screws 305, the two U-shaped plates 303 can be moved closer or further apart, thereby separating or fitting the clamping blocks 302. This fixes and loosens the cable 101, facilitating the adjustment of the position of the end of the sleeve 2.

[0034] Working principle: In use, the first connector 102 and the second connector 103 are respectively plugged into the corresponding plug-in ports to connect to the control system. The sleeve 2 protects the wire harness 1 to prevent the cables 101 from getting tangled and to prevent the cables 101 from being cut. The sleeve 2 is made of corrugated tube and rubber hose nested inside and outside, which makes it easy to bend with the cables 101. The fireproof cloth layer 203 between the inner tube 202 and the outer tube 201 improves the high temperature resistance of the wire harness 1. The end of the sleeve 2 can move on the wire harness 1 to suit different separation points of the cables 101 and facilitate the connection of the cables 101. A fixing mechanism 3 is set at the movable end of the sleeve 2 for fixing. By turning the screw 305, the clamp 302 is separated or attached, thereby loosening or confining the cables 101 and facilitating the position adjustment of the end of the sleeve 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
