[0001] This utility model relates to the technical field of automotive wiring harness fixing ties, and in particular to bidirectional detachable ties for fixing automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are the main network components of automotive circuits. Their role in the vehicle is to transmit and exchange power and data signals from the electrical system, thereby fulfilling the functions and requirements of the electrical system.

[0003] When wiring, automotive wiring harnesses need to be secured. Cable ties are typically used for this purpose. Cable ties are generally made of materials such as nylon, possessing a certain degree of flexibility and strength. They can be flexibly adjusted according to the thickness and shape of the wiring harness, binding the harness together and fixing it in a designated position. Cable tie securing is simple to operate, inexpensive, and suitable for various complex wiring scenarios.

[0004] Traditional cable ties can only be tightened more and more when used for fixing, and the tightness cannot be adjusted according to the situation. Over-tightening may damage the wire harness and affect its performance. They also cannot be disassembled and reused. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bidirectional detachable cable tie for fixing automotive wiring harnesses that can be adjusted according to the situation to avoid damage to the wiring harness caused by excessive tightness and affecting its performance.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional detachable cable tie for fixing automotive wiring harnesses, comprising a chuck and a locking assembly. The right end of the chuck is integrally connected to a retaining ring, and multiple locking grooves are equidistantly spaced at the bottom end of the chuck. The locking assembly includes a contact piece, which is integrally fixedly connected to the lower side of the inner wall of the left end of the retaining ring. A locking block is integrally connected to the upper side of the right end of the contact piece, matching the locking groove. The locking block is perpendicular to the contact piece. Limiting blocks are integrally connected to both the front and rear ends of the contact piece. A pressure plate is integrally connected to the end of the limiting block furthest from the contact piece. Limiting grooves are provided through both the front and rear ends of the retaining ring. Two sets of limiting blocks are slidably installed in the two sets of limiting grooves, and the inner sides of the two sets of pressure plates are in contact with the front and rear ends of the retaining ring. A U-shaped spring sheet is fixedly connected between the inner wall of the contact piece and the inner wall of the left side of the retaining ring.

[0008] Preferably, positioning grooves are provided on the inner sidewall of the contact piece and the left inner wall of the retaining ring, and the positioning grooves have the same thickness as the U-shaped spring sheet. The left and right ends of the U-shaped spring sheet are respectively fixedly connected in the two sets of positioning grooves.

[0009] Preferably, ribs are fixedly connected between the front and rear ends and the bottom end of the right side of the cartridge and the left end of the clasp.

[0010] Preferably, the left end of the cartridge is integrally connected to a plug.

[0011] Preferably, both sets of tablets have anti-slip stripes on their right ends.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the cassette is bent downwards and inserted into the retaining ring, so that the side of the cassette with the locking groove faces the locking block. The locking groove is a right-angled trapezoid, with a vertical surface on the left and an inclined surface on the right. The cable harness is looped through the cassette. After the cassette passes through the retaining ring, the vertical surface of the locking groove is on the upper side, and the inclined surface is on the lower side. By pulling the cassette upwards, the lower inclined surface of the locking groove presses against the locking block to the left, compressing the U-shaped spring sheet. This allows the locking groove to be continuously pulled upwards. The rebound generated by the compression of the U-shaped spring sheet... The locking block engages with the locking groove at the appropriate position, tightening the strap and securing the wire harness. The locking block, acting against the vertical surface, locks the strap, preventing it from retracting. If it is too tight or needs to be removed, hook your hand onto the pressure plate and press the contact plate to the left using the limit block. This further compresses the U-shaped spring, causing the locking block to disengage from the locking groove. The strap can then retract or be pulled out of the retaining ring to adjust the tightness or remove it. This allows for adjustment of the tightness as needed, preventing damage to the wire harness from excessive tightness and ensuring its performance. The strap is removable and reusable.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] Example

[0023] Please see Figures 1-7 This utility model discloses a bidirectional detachable cable tie for fixing automotive wiring harnesses, comprising a clasp 1 and a contact piece 4. A retaining ring 2 is integrally connected to the right end of the clasp 1. Multiple locking grooves 3 are equidistantly spaced at the bottom end of the clasp 1. The contact piece 4 is integrally fixedly connected to the lower side of the inner wall of the left end of the retaining ring 2. A locking block 5 is integrally connected to the upper right end of the contact piece 4, matching the locking groove 3. The locking block 5 is perpendicular to the contact piece 4. Limiting blocks 6 are integrally connected to both the front and rear ends of the contact piece 4. The end of the limiting block 6 furthest from the contact piece 4 is integrally connected to... The pressure plate 7 and the retaining ring 2 both have through-holes 8 at their front and rear ends. Two sets of limiting blocks 6 are slidably installed in the two sets of limiting grooves 8, and the inner sides of the two sets of pressure plates 7 are in contact with the front and rear ends of the retaining ring 2, respectively. A U-shaped spring plate 9 is fixedly connected between the inner wall of the contact plate 4 and the inner wall of the left side of the retaining ring 2. In use, the card strap 1 is bent downwards and inserted into the retaining ring 2, so that the side of the card strap 1 with the locking groove 3 faces the locking block 5. The locking groove 3 is in the shape of a right-angled trapezoid, with the left side being a vertical surface and the right side being an inclined surface. After the cable 1 is looped through the retaining ring 2, the vertical surface of the locking groove 3 is on the upper side, and the inclined surface is on the lower side. By pulling the cable 1 upward, the lower inclined surface of the locking groove 3 presses the locking block 5 to the left, compressing the U-shaped spring 9. This allows the locking groove 3 to be pulled upward continuously. The rebound generated by the compression of the U-shaped spring 9 allows the locking block 5 to engage in the locking groove 3 at the appropriate position, tightening the cable 1 and thus binding the wire harness. Under the action of the surface, the cassette 1 is locked so that it will not retract. If it is too tight or needs to be disassembled, you can hook your hand on the pressure plate 7 and press the contact plate 4 to the left through the limit block 6. The U-shaped spring plate 9 is further compressed, so that the locking block 5 is disengaged from the locking groove 3. Then the cassette 1 can be retracted or pulled out from the retaining ring 2 to adjust the tightness or disassemble it. This allows you to adjust the tightness according to the situation, avoid damage to the wire harness caused by over-tightening, and avoid affecting the performance of the wire harness. It can be disassembled and reused.

[0024] Positioning grooves 10 are provided on the inner side wall of the contact piece 4 and the left inner wall of the retaining ring 2. The positioning grooves 10 have the same thickness as the U-shaped spring piece 9. The left and right ends of the U-shaped spring piece 9 are fixedly connected in the two sets of positioning grooves 10 respectively. By setting the positioning grooves 10, the U-shaped spring piece 9 can be limited to prevent it from disengaging when the contact piece 4 is pressed, thereby making the connection of the U-shaped spring piece 9 more stable.

[0025] Ribs 11 are fixedly connected between the front and rear ends and the bottom end of the right side of the cassette 1 and the left end of the retaining ring 2. By setting the ribs 11, the connection between the cassette 1 and the retaining ring 2 can be made more secure, so that the retaining ring 2 will not break from the cassette 1.

[0026] The left end of the cartridge 1 is integrally connected to a plug 12; by setting the plug 12, the cartridge 1 can pass through the retaining ring 2 more easily.

[0027] Both sets of pressure plates 7 are provided with anti-slip stripes 13 on the right end; by providing anti-slip stripes 13, when the hand hooks the pressure plate 7 and presses the contact plate 4 to the left, the hand is less likely to slip.

[0028] This utility model discloses a bidirectional detachable cable tie for securing automotive wiring harnesses. Its working principle is as follows: When in use, the cable tie 1 is bent downwards and inserted into the retaining ring 2, with the side of the cable tie 1 having the locking groove 3 facing the locking block 5. The locking groove 3 is a right-angled trapezoid, with a vertical surface on the left and an inclined surface on the right. The cable tie 1 is used to secure the wiring harness. After the cable tie 1 passes through the retaining ring 2, the vertical surface of the locking groove 3 is on the upper side, and the inclined surface is on the lower side. By pulling the cable tie 1 upwards, the inclined surface on the lower side of the locking groove 3 compresses the locking block 5 to the left, compressing the U-shaped spring 9. This allows for continuous upward pulling of the locking groove 3. The compression of the U-shaped spring 9 generates a return force... The spring allows the locking block 5 to engage with the locking groove 3 at the appropriate position, tightening the strap 1 and securing the wire harness. Under the action of the locking block 5 and the vertical surface, the strap 1 is locked, preventing it from retracting. If it is too tight or needs to be disassembled, you can hook your hand onto the pressure plate 7 and press the contact plate 4 to the left through the limit block 6. The U-shaped spring plate 9 is further compressed, causing the locking block 5 to disengage from the locking groove 3. Then the strap 1 can be retracted or pulled out of the retaining ring 2 to adjust the tightness or disassemble it. It should be noted that all other parts except the U-shaped spring plate 9 are made of nylon, while the U-shaped spring plate 9 is made of thin stainless steel spring sheet.

[0029] The bidirectional detachable cable tie for fixing automotive wiring harnesses of this utility model can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
