Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a high-strength wire harness suitable for high and low temperature environments. Background Technology

[0002] Cable ties, also known as wire ties, cable bundles, or locking straps, are straps used to bundle things together. They are generally classified by material into nylon cable ties, stainless steel cable ties, and powder-coated stainless steel cable ties, and by function into ordinary cable ties, retractable cable ties, label cable ties, fixed locking cable ties, pin-type cable ties, heavy-duty cable ties, and so on.

[0003] High and low temperature resistant cable ties are a cable management solution designed specifically for extreme temperature environments. Made from high-performance engineering plastics (such as reinforced nylon, PEEK, or special modified materials), they maintain excellent structural strength and flexibility across a wide temperature range of -60℃ to 200℃. Their unique molecular structure effectively resists UV radiation, chemical corrosion, and mechanical stress, ensuring long-term stable operation in scenarios such as automotive engine compartments, aerospace equipment, polar research instruments, or high-temperature industrial equipment. The product has obtained international certifications such as UL and RoHS. The toothed locking structure provides different binding tension levels from 5kg to 50kg, while also offering flame retardant and insulation properties, making it suitable for securing and protecting cable harnesses under complex working conditions.

[0004] Some high and low temperature resistant cable ties use a snap-lock design for easy disassembly and reuse. However, the tensile strength of snap-lock cable ties is far less than that of fixed-lock cable ties. In some situations requiring high-intensity operations, snap-lock cable ties cannot be used. Therefore, we propose a high-strength cable tie suitable for high and low temperature environments. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength cable tie suitable for high and low temperature environments, in order to solve the problem mentioned in the background art that some high and low temperature resistant cable ties adopt a snap-lock design for easy disassembly and reuse, but the tensile strength of snap-lock cable ties is far less than that of fixed-lock cable ties, and snap-lock cable ties cannot be used in some situations requiring high-intensity operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wire harness cable tie suitable for high and low temperature environments, comprising: a wire harness, the upper surface of which is evenly distributed with several locking teeth, a connector fixedly connected to the front end of the wire harness, a through hole being formed at the upper end of the connector near the rear edge, a locking tooth being fixedly connected to the middle of the rear end of the inner wall of the through hole, a movable block being movably connected inside the connector, a cavity being formed at the middle of the upper surface of the movable block, two sets of spring pieces being fixedly connected to the rear end of the inner wall of the cavity, a resistance block being fixedly connected to the front end of the spring pieces, and a rubber pad being fixedly connected to the rear end of the movable block.

[0007] Preferably, a groove 5 is provided on the upper surface of the movable block near the front end, a bolt is fixedly connected to the front end of the connector, a stop plate is rotatably connected to the outside of the bolt, a slot is provided on the left side of the stop plate, a button is movably connected inside the slot, and anti-slip strips are provided on the upper and lower surfaces of the movable block near the front edge.

[0008] Preferably, the resistance block and the connector are integrally injection molded, and the resistance block is elastically connected to the moving block through the spring sheet, and the moving block is slidably connected to the connector.

[0009] Preferably, the distance between the connector and the anti-reverse tooth is adapted to the thickness of the cable tie, and the shape of the locking tooth is adapted to the anti-reverse tooth.

[0010] Preferably, the height of the resistance block is equal to the inner diameter of the cavity, and the resistance block is movably connected to the moving block.

[0011] Preferably, the position of the stop piece corresponds to the position of the groove 5, the inner diameter of the slot is the same as the outer diameter of the button, and the bottom opening of the slot is slightly smaller than the diameter of the button.

[0012] Compared with the prior art, this utility model provides a high-strength wire harness cable tie suitable for high and low temperature environments, which has the following beneficial effects: the connector of the high-strength wire harness cable tie suitable for high and low temperature environments adopts a front-end pull-out movable block, which achieves the purpose of unlocking by reverse decompression. The anti-reverse teeth are still fixedly connected to the connector, which will not affect the tensile strength of the cable tie. In addition, a rubber pad is added to the rear end of the movable block to increase the friction between the cable tie and the back of the connector, thereby increasing the compressive strength.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5 As shown, a high-strength wire harness cable tie suitable for high and low temperature environments includes: a wire harness 1, with several evenly distributed teeth 2 on the upper surface of the wire harness 1 for locking; a connector 3 is fixedly connected to the front end of the wire harness 1; a hole 31 is provided through the upper end of the connector 3 near the rear edge for the wire harness 1 to pass through; a retaining tooth 32 is fixedly connected to the middle of the rear end of the inner wall of the hole 31; the distance between the connector 3 and the retaining tooth 32 is adapted to the thickness of the wire harness 1; the shape of the teeth 2 is adapted to the retaining tooth 32 for locking; fixing it inside the connector 3 does not affect the tensile strength of the wire harness 1; a movable block 4 is movably connected inside the connector 3; a cavity 41 is provided in the middle of the upper surface of the movable block 4. Two sets of spring plates 42 are fixedly connected to the rear end of the inner wall of cavity 41. A resistance block 33 is fixedly connected to the front end of the spring plate 42. The resistance block 33 and the connector 3 are integrally injection molded. The resistance block 33 is elastically connected to the moving block 4 through the spring plate 42. The moving block 4 is slidably connected to the connector 3. The height of the resistance block 33 is equal to the height of the inner diameter of cavity 41. The resistance block 33 is movably connected to the moving block 4. When the moving block 4 is pulled outward, the rear end of the moving block 4 moves away from the anti-retraction tooth 32. At this time, the cable tie 1 can be untied. When the moving block 4 is released, the moving block 4 returns to its original position under the pushing force of the spring plate 42. At this time, the cable tie 1 can be reused. A rubber pad 43 is fixedly connected to the rear end of the moving block 4 to increase the friction with the back of the cable tie 1, thereby increasing the tensile strength.

[0025] like Figures 1 to 3As shown, a groove 45 is provided on the upper surface of the movable block 4 near the front end. A bolt 34 is fixedly connected to the front end of the connector 3. A stop piece 341 is rotatably connected to the outside of the bolt 34. The position of the stop piece 341 corresponds to the position of the groove 45. The stop piece 341 can engage with the groove 45 to fix the movable block 4. A slot 342 is provided on the left side of the stop piece 341. A latch 343 is movably connected inside the slot 342. The inner diameter of the slot 342 is the same as that of the latch 343. The outer diameter of 343 is the same, and the bottom opening of the slot 342 is slightly smaller than the diameter of the button 343. Pressing down slightly on the left side of the stop piece 341 can lock the slot 342 onto the button 343, thus locking the moving block 4. Lifting up slightly on the left side of the stop piece 341 can disengage the slot 342 from the button 343, thus releasing the locked state of the moving block 4. Anti-slip strips 44 are provided on the upper and lower surfaces of the moving block 4 near the front edge to prevent slipping.

[0026] Working principle: When using this high-strength cable tie suitable for high and low temperature environments, the worker first holds the connector 3 with one hand and uses the other hand to bundle the wires to be bundled together with the cable tie 1, with the side with the locking teeth 2 facing inward. Then, the tail of the cable tie 1 is inserted into the connector 31 and pulled outward. At this time, the anti-reverse teeth 32 engage with the locking teeth 2, fixing the cable tie 1 in place, thus completing the bundling of the wire harness. The rear end of the moving block 4 is fixedly connected to a rubber pad 43, which increases the friction between the moving block 4 and the back of the cable tie 1, thereby increasing the tensile strength. When it is necessary to remove the cable tie 1, a slight upward lift of the anti-reverse teeth 32 completes the bundling of the wire harness. The left side of the movable piece 341 disengages the slot 342 from the button 343, releasing the locking state of the movable block 4. Then, pinch the front end of the movable block 4 and pull it outward to move the rubber pad 43 away from the cable tie 1, allowing the cable tie 1 to be pulled out. After releasing the movable block 4, it returns to its original position under the pushing force of the spring piece 42. Finally, move the stop piece 341 into the groove 45 and press down slightly on the left side of the stop piece 341 to make the slot 342 snap onto the button 343, thus locking the movable block 4 and achieving the effect of reuse. This is the working principle of the high-strength cable tie suitable for high and low temperature environments.

[0027] 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.
