Description

Technical Field

[0001] This utility model mainly relates to the technical field of wire harness cable ties, specifically a high-strength wire harness locking tongue structure. Background Technology

[0002] The main function of wire harness cable ties is to securely fasten wire harnesses, ensuring they are firmly and reliably fixed to various parts of the vehicle body, such as sheet metal holes, bolts, and steel plates. This fastening helps prevent the wire harness from interfering with other components due to vibration or movement during vehicle operation, thus avoiding damage to the wire harness. By rationally planning the routing and fixing positions of the wire harness and using wire harness cable ties for fixing and bundling, the entire vehicle's wire harness can look neater and more orderly, thereby improving the overall quality of the vehicle. Wire harness cable ties usually come with a clip for installing studs, but existing clips can only be used with studs of the corresponding specifications, resulting in poor compatibility and requiring the purchase of additional studs.

[0003] According to application number 201921915561.9, an automotive wiring harness cable tie includes a fixing seat with a fixing groove and a strip-shaped cable body. A connecting groove is provided on the end face of the fixing seat, and one end of the cable body has a columnar connector. The connector is axially inserted into the connecting groove and can rotate relative to the fixing seat. A snap-fit ​​structure is provided in the connecting groove to axially position the connector.

[0004] The above document is applicable to wire harnesses in different directions, making it more versatile, but it cannot be adapted to studs of different specifications, and it cannot reduce procurement costs. Utility Model Content

[0008] Preferably, the side of the latch frame is a right-angled trapezoidal structure, the latch frame includes a trapezoidal groove in the middle, and the cable tie is connected to the narrower end of the latch frame, with the connection point being integrally molded.

[0009] Preferably, the toothed belt lock tongue and the lock tongue frame connection point are integrally molded, one end of the toothed belt lock tongue is a three-layer lock tooth, the other end is an arc structure, the toothed belt lock tongue lock tooth is away from the buckle frame, and the toothed belt lock tongue top has upward contraction capability.

[0010] Preferably, the buckle frame is cylindrical, including a cross-shaped clamping groove arranged in the middle, and the buckle frame is connected with the wider end of the lock tongue frame, and the connection point is integrally molded.

[0011] Preferably, four screw column lock tongues are arranged at the upper half position of the cross-shaped clamping groove, the screw column lock tongue and the cross-shaped clamping groove connection point are integrally molded, one end of the screw column lock tongue is a three-layer lock tooth, the other end is an arc structure, the screw column lock tongue lock tooth faces the central axis of the buckle frame, and the screw column lock tongue bottom has downward contraction capability.

[0012] Preferably, the strap includes a pull belt arranged away from the lock tongue frame, and a toothed belt arranged at the bottom of the pull belt.

[0013] In summary, the technical scheme mainly has the following beneficial effects:

[0014] In the embodiment, by arranging a cross-shaped clamping groove in the buckle frame, and arranging four three-layer lock tongue structure screw column lock tongues in the cross-shaped clamping groove, T5 / M5 / M6 / T6 four specifications of screw columns can be simultaneously matched, and the procurement and management cost of screw columns is reduced.

[0015] Through the design of the lock tongue structure with one end fixed and one end retractable, it can be ensured that the toothed belt strip and the screw column can only be installed in the designed direction and cannot be pulled out, and the plug-in performance of the matched screw column is greatly improved. By arranging a pull belt at one end of the strap and a toothed belt at the bottom of the pull belt, the friction during pulling can be increased, and the strap can be prevented from slipping during installation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a high-strength wire harness latch structure includes a cable tie 1, a latch frame 2 at one end of the cable tie 1, a snap-fit ​​frame 3 at the other end of the latch frame 2, a toothed strip 4 at the top center of the cable tie 1, a toothed latch 5 at one end inside the latch frame 2, and four stud latches 6 arranged in a ring inside the snap-fit ​​frame 3. The side of the latch frame 2 is a right-angled trapezoidal structure, and the latch frame 2 includes a trapezoidal groove 21 in the middle. The cable tie 1 is connected to the narrower end of the latch frame 2, and the connection point is integrally molded. The toothed latch 5 is integrally molded to the latch frame 2. One end of the toothed latch 5 has three-layer latch teeth, and the other end has an arc-shaped structure. The latch teeth of the toothed latch 5 face away from the snap-fit ​​frame 3, and the top of the toothed latch 5 has an upward retraction capability. The cable tie 1 includes a pull strap 11 at the end away from the latch frame 2 and a toothed strip 12 at the bottom of the pull strap 11.

[0024] It should be noted that when using cable tie 1, the cable tie is inserted into the locking tongue frame 2 from the oblique side of the locking tongue frame 2, so that the toothed strip 4 can engage with the toothed locking tongue 5. Since the top of the toothed locking tongue 5 has the ability to retract upward, when the toothed strip 4 is inserted, the toothed locking tongue 5 will retract upward so that the toothed strip 4 can enter smoothly. When the toothed strip 4 is pulled outward, the toothed strip 4 is locked because the toothed locking tongue 5 cannot retract downward.

[0025] As described above, when using this device, after wrapping the cable tie 1 around the wire harness, insert it into the trapezoidal groove 21 of the locking tongue frame 2 so that the toothed strip 4 can engage with the toothed locking tongue 5. By pulling the cable tie 1 with the pull strap 11 and the grinding toothed strap 12, the toothed locking tongue 5 will retract upward, allowing the toothed strip 4 to enter smoothly. Use scissors to cut off the excess cable tie 1 to tightly tie the wire harness together.

[0026] Please refer to the attached document carefully. Figure 1 , 2As shown in Figs. 1-4, the buckle frame 3 is cylindrical and includes a cross-shaped clamping groove 31 in the middle, the buckle frame 3 is connected with the wider end of the lock tongue frame 2, and the connecting point is integrally molded; four stud lock tongues 6 are arranged at the upper half of the cross-shaped clamping groove 31, the connecting point of the stud lock tongue 6 and the cross-shaped clamping groove 31 is integrally molded, one end of the stud lock tongue 6 is the lock tooth of the three-layer lock tongue, the other end is an arc structure, the lock tooth of the stud lock tongue 6 faces the central axis of the buckle frame 3, and the bottom of the stud lock tongue 6 has a downward contraction capability.

[0027] It should be noted that the stud is inserted into the cross-shaped clamping groove 31 from above the buckle frame 3, and the downward contraction capability of the stud lock tongue 6 facilitates the smooth entry of the stud when being inserted, and when the stud moves upward, the three-layer lock tongue of the stud lock tongue 6 locks the threads of the stud, so that the stud cannot be pulled out.

[0028] When the wire harness is tied, the stud is inserted into the cross-shaped clamping groove 31 from above the buckle frame 3, a suitable fixing position is selected, the stud is installed at the position by using a screwdriver, and in this process, the downward contraction capability of the stud lock tongue 6 facilitates the smooth entry of the stud, and after the stud is tightened, the installation is completed.

[0029] The above embodiments only illustrate the technical idea of the present application, and cannot limit the protection scope of the present application, and any modification made on the basis of the technical scheme according to the technical idea of the present application falls within the protection scope of the present application.
