Description

Technical Field

[0001] The invention relates to the technical field of electronic wire harnesses, in particular to an electronic wire harness with a pulling protection structure. Background Art

[0002] In the patent document with application announcement number CN118198813B, it includes. Advantages: The present invention sets a central stopper composed of a stopper cylinder and an end cover in the middle of the wire harness, and limits the wire part of the data connection line through the buried wire groove set on the stopper cylinder, so as to ensure the neatness of the wire harness, and through the rotation of the winding shaft column set inside the stopper cylinder, the damping swivel and the damping dial block on it wind up the excess length of the data connection line, thereby solving the problem of data confusion caused by the different lengths of the connection lines in the current wire harness, reducing the construction process and improving the installation efficiency.

[0003] In the prior art including the above-mentioned patents, the tensile strength of the electronic wiring harness during use needs to be enhanced in addition to the connection points. When the electronic wiring harness breaks due to strong tensile force, it will cause power outages, short circuits and other problems affecting normal use. Since the wiring harness is relatively soft, it is also difficult to find the source of the breakage at a later stage and needs to be replaced as a whole. Summary of the invention

[0004] The problem to be solved by the present invention is that the electronic wire harness itself is relatively weak and has a relatively weak pulling resistance, and is easily broken and damaged when subjected to left and right lateral pulling forces.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: an electronic wiring harness with a pulling protection structure, comprising a wiring harness rubber sleeve, a copper core is arranged inside the wiring harness rubber sleeve, a tensile structure is arranged on the top and bottom of the copper core, and a fixing groove is arranged on the bottom of the inner wall of the wiring harness rubber sleeve; The tensile structure includes a tensile block, the bottom of which is in close contact with the surface of the copper core, the tensile block is trapezoidal in shape, a slide groove is provided inside the tensile block, through grooves are provided on the front and rear sides of both sides of the tensile block, blocks are fixed on the top and bottom of the inner wall of the slide groove, and a slider is slidably provided inside the slide groove.

[0006] Preferably, a plurality of power blocks are provided at the top and bottom of the sliding block in a rectangular array, and the power blocks are cylindrical and the tops thereof are closely attached to the tops of the sliding grooves.

[0007] Preferably, a spring plate is fixedly provided on one side of the sliding block, and the spring plates on one side of each tensile block are fixedly connected in an integral shape, and the spring plates are adapted to the through slots.

[0008] Preferably, a connecting plate is provided at the bottom of the tensile block, and an electric contact terminal is provided at the bottom of the connecting plate.

[0009] Preferably, connecting plates are fixedly provided on both sides of the tensile block, a fixing block is fixedly provided on the top of the connecting plate, and the fixing block is buried inside the wiring harness rubber sleeve.

[0010] Preferably, connectors are provided on both sides of the wiring harness rubber sleeve, and wiring terminals are provided on the front sides of the connectors.

[0011] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) A tensile structure is provided inside the wiring harness rubber sleeve, and a spring plate is provided on the tensile structure. The spring plate will not affect the normal up and down bending of the wiring harness. The spring plate can improve the overall resilience of the wiring harness, so that it can quickly restore its shape after bending. After the wiring harness is subjected to tension, the spring plate cooperates with the slider to be limited by the block to increase the overall tensile resistance of the wiring harness. If the tensile force continues and reaches a certain level, the block will break. At this time, the wiring harness has exceeded the overall maximum tensile resistance and the copper core will break. After the copper core breaks, the spring plate can cooperate with the slider to continue to connect the current, and the wiring harness can continue to transmit current without causing power outages. Compared with ordinary wiring harnesses that lose current and power outages after breaking, the present invention can not only increase the overall tensile resistance of the device, but also continue to connect and provide current transmission after the copper core breaks; (2) Connecting plates and fixing blocks are also provided on both sides of the tensile block. The fixing block is provided inside the wiring harness rubber sleeve. When the wiring harness is broken, the maintenance personnel only need to gently pull the wiring harness, and the connecting block will drive the fixing block to move sideways. Then a recessed position will appear on the rubber sleeve. The recessed position is the position where the wiring harness is broken, so that the maintenance personnel can quickly locate the broken position at the first time and choose to repair or replace it, without spending a long time to eliminate it bit by bit.

[0016] like Figures 1 to 10 As shown, an electronic wiring harness with a pulling protection structure provided by the present invention comprises: a copper core 9 is provided inside a wiring harness rubber sleeve 1, a tensile structure 2 is provided on the top and bottom of the copper core 9, and a fixing groove is provided on the bottom of the inner wall of the wiring harness rubber sleeve 1; The tensile structure 2 includes a tensile block 204, the bottom of which is tightly attached to the surface of the copper core 9. The tensile block 204 is trapezoidal in shape, and a slide groove 4 is provided inside the tensile block 204. Through grooves are provided on the front and rear sides of both sides of the tensile block 204. Blocks 203 are fixed on the top and bottom of the inner wall of the slide groove 4, and a slider 201 is slidably provided inside the slide groove 4.

[0017] A plurality of power blocks 206 are provided in a rectangular array at the top and bottom of the slider 201 . The power blocks 206 are cylindrical and the tops thereof are closely attached to the tops of the slide slots 4 .

[0018] A spring plate 202 is fixedly provided on one side of the sliding block 201 , and the spring plates 202 on one side of each tensile block 204 are fixedly connected to form an integral body, and the spring plates 202 are adapted to the through slots.

[0019] A connecting plate 205 is provided at the bottom of the tensile block 204 , and an electric contact terminal 5 is provided at the bottom of the connecting plate 205 .

[0020] Connecting plates 7 are fixedly provided on both sides of the tensile block 204 , and a fixing block 6 is fixedly provided on the top of the connecting plate 7 . The fixing block 6 is buried inside the wiring harness rubber sleeve 1 .

[0021] Connectors 3 are provided on both sides of the wiring harness rubber sleeve 1 , and wiring terminals 8 are provided on the front of the connector 3 .

[0022] The working principle and use process of the present invention are as follows: when the wiring harness is subjected to lateral pulling force from the left and right sides during use, the wiring harness sleeve 1, the spring plate 202 and the copper core 9 can provide initial tensile resistance. When the pulling force increases, the slider 201 inside the tensile block 204 will be pulled to one side by the spring plate 202, and will be fixed by the clamping block 203 after moving to a certain position. The clamped clamping block 203 can provide further tensile resistance for the wiring harness. When encountering instantaneous or continuous high-strength tensile force, the tensile strength exceeds the resistance strength of the copper core 9 and the clamping block 203 themselves, which will cause the copper core 9 and the clamping block 203 to break. After the copper core 9 breaks, the current will be conducted to the electric shock terminal 5 and the current will be transmitted to the tensile block 20 4, after the block 203 breaks, the spring plate 202 will extend outward for a distance, and the current will continue to be transmitted along with the spring plate 202, so that even if the copper core 9 breaks, the current can still be kept from being interrupted and can continue to be transmitted, avoiding circuit breakage and power outages. When the maintenance personnel find the break and perform maintenance, if the length of the wire harness is long and the break position cannot be quickly determined, the wire harness rubber sleeve 1 can be gently pulled, and the two tensile blocks 204 at the break will drive the connecting plate 7 to move, and the connecting plate 7 will drive the fixing block 6 to tilt. The tilted fixing block 6 will form an obvious pit on the surface of the wire harness rubber sleeve 1, and the user can quickly find the break position of the copper core 9 according to the position of the pit.
