Description

Technical Field

[0001] This utility model is a self-locking structure for wire harnesses, belonging to the field of electrical engineering. Background Technology

[0002] In current wire harness applications, a problem of wobbling exists after assembly, affecting the performance and stability of the wire harness. For example, the assembled wire harness may shift back and forth, which can lead to unstable connections, affecting signal transmission or power supply. Furthermore, long-term wobbling can cause wear, breakage, and other damage, reducing the lifespan of the wire harness. In fields with high reliability requirements, such as automotive and aerospace, the impact of this wobbling problem is even more severe. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-locking structure for wire harnesses to solve the problems mentioned in the background technology. This utility model prevents the cables from shifting back and forth and ensures that they remain stable during use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire harness self-locking structure, comprising a base plate, two rubber sleeves mounted on one side of the base plate, a cable inserted inside the rubber sleeves, a tail cap fitted onto the cable, the tail cap fitting onto the rubber sleeves and engaging with them, a plurality of claws equidistantly arranged in a ring shape inside the tail cap, the claws being inside the rubber sleeves and in contact with the cable and rubber sleeves in a compressed state, and a first fixing hole being provided at each of the two opposite corners of the base plate, with a positioning component installed at the location of the first fixing hole on the base plate.

[0005] Furthermore, the positioning component includes a semi-circular groove. The portion of the base plate where the first fixing hole is located has a semi-circular groove, which divides the first fixing hole into two. A disc is inserted into the semi-circular groove. A screw hole aligned with the first fixing hole is located in the middle of one side of the disc. A connecting screw threaded into the screw hole is inserted into the first fixing hole. An ear plate is mounted on the outer surface of the disc. A U-shaped plate is mounted on the end of the ear plate away from the disc via a fastener formed by a screw and nut. One end of one U-shaped plate is connected to one end of another U-shaped plate via a fastener formed by a screw and nut. An L-shaped plate is mounted on the U-shaped plate furthest from the ear plate via a fastener formed by a screw and nut. A second fixing hole is located on one side of the L-shaped plate.

[0006] Furthermore, two first circular holes are provided at the contact points between the ear plate and the U-shaped plate, two second circular holes are provided on each of the two parallel side surfaces of the U-shaped plate, and two third circular holes are provided at the contact points between the L-shaped plate and the U-shaped plate. Screws connecting the U-shaped plate and the ear plate pass through the first circular holes and the corresponding second circular holes, screws connecting the two U-shaped plates pass through the two corresponding second circular holes, and screws connecting the U-shaped plate and the L-shaped plate pass through the second circular holes and the corresponding third circular holes.

[0007] Furthermore, the ear plate has an "L" shaped structure, and the ear plate and the disc are integrally formed.

[0008] Furthermore, the outer surface of the rubber sleeve is connected and fixed with two protrusions, and the outer surface of the tail cap is provided with two slots, in which the protrusions are inserted.

[0009] Furthermore, the tail cover has two notches at one end near the seat plate, and each of the two notches is provided with a guide strip that contacts the inner wall of the notch. The guide strip is connected and fixed to the rubber sleeve.

[0010] Furthermore, a terminal head is installed at one end of the cable, and a small hole is opened on one side of the terminal head.

[0011] Furthermore, a rib is installed between the two rubber sleeves. The rib has an "I"-shaped structure and is integrally formed with the rubber sleeve and the seat plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Multiple claws, arranged in a ring at equal intervals inside the tail cap, are compressed within the rubber sleeve, making close contact with the cable and the sleeve. This creates a strong locking force on the cable, allowing the base plate to be installed on the required carrier. This prevents the cable from shifting back and forth, improving its stability and ensuring it remains stable during use. It also reduces problems such as unstable connections, signal transmission issues, or power supply disruptions caused by shaking, thus extending the cable's lifespan.

[0014] 2. Use connecting screws to confine the disc in the circular groove. Then, increase or decrease the number of U-shaped plates between the L-shaped plate and the ear plate. Use screws and nuts to connect the L-shaped plate, U-shaped plate, and ear plate. This allows the distance between the second fixing hole and the base plate to be changed according to the needs of on-site installation, so that the bolts that restrict the position of the base plate can be installed in different positions as needed.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a wire harness self-locking structure, including a base plate 1, two rubber sleeves 2 are installed on one side of the base plate 1, and a rib frame 15 is installed between the two rubber sleeves 2. The rib frame 15 is an "I" shaped structure. The rib frame 15, rubber sleeves 2, and base plate 1 are integrally formed. The rib frame 15, rubber sleeves 2, and base plate 1 are made of thermoplastic elastomer. The rib frame 15 improves the stability of the structure.

[0024] See Figure 1 , Figure 2 , Figure 4 and Figure 5A cable 4 is inserted inside the rubber sleeve 2. A terminal head 11 is installed at one end of the cable 4. A small hole is opened on one side of the terminal head 11. A tail cover 3 is fitted onto the cable 4. The tail cover 3 is fitted onto the rubber sleeve 2 and is snapped into place. Two protrusions 12 are fixedly connected to the outer surface of the rubber sleeve 2. Two slots 18 are opened on the outer surface of the tail cover 3 so that the protrusions 12 are inserted into the slots 18, thus completing the snapping of the tail cover 3 and the rubber sleeve 2. Two notches 19 are opened at the end of the tail cover 3 near the base plate 1. Guide strips 5 are provided in both notches 19 and contact the inner wall of the notches 19. The guide strips 5 are fixedly connected to the rubber sleeve 2 so that when the tail cover 3 is fitted onto the rubber sleeve 2, the guide strips 5 and the notches 19 cooperate with each other to achieve the function of guiding and limiting.

[0025] See Figures 1-5 The tail cap 3 has multiple claws 14 evenly spaced in a ring shape. These claws 14 are located within the rubber sleeve 2 and are in contact with the cable 4 and the rubber sleeve 2 under pressure. The base plate 1 has two diagonally opposite corners with first fixing holes 17. In this self-locking structure of the cable harness, multiple claws 14 are evenly distributed around the inside of the tail cap 3. When the tail cap 3 is fitted onto the rubber sleeve 2, these claws 14 are pressed against the inner wall of the rubber sleeve 2, thus tightly adhering to the cable 4 and the rubber sleeve 2. This tight contact provides strong binding force to the cable 4. After the claws 14 secure the cable 4, the base plate 1 is installed onto the corresponding carrier, thus firmly fixing the cable 4. This effectively prevents the cable 4 from shifting back and forth, whether in a static or dynamic environment. The improved stability of the cable 4 ensures it remains stable during operation, greatly reducing a series of problems caused by shaking. Issues such as loose connections, signal transmission interruptions or interference, and unstable power supply can all be effectively prevented. This not only ensures the normal operation of the equipment, but also greatly extends the service life of cable 4, reducing the increased costs and wasted time caused by frequent replacement of cable 4.

[0026] See 1. Figure 2 and Figure 4A semi-circular groove 16 is provided at the location where the first fixing hole 17 is opened on the base plate 1. The first fixing hole 17 is divided into two by the semi-circular groove 16. A disc 13 is inserted into the semi-circular groove 16. A screw hole is opened in the middle of one side of the disc 13, which is aligned with the first fixing hole 17. A connecting screw 6 is inserted into the first fixing hole 17 and threaded into the screw hole. An ear plate 7 is installed on the outer surface of the disc 13. The "L"-shaped ear plate 7 is integrally formed with the disc 13. A U-shaped plate 8 is installed on the end of the ear plate 7 away from the disc 13 by a fastener formed by screws and nuts. One end of one U-shaped plate 8 is connected to one end of another U-shaped plate 8 by a fastener formed by screws and nuts. The U-shaped plate 8 farthest from the ear plate 7 is... Plate 8 is fastened with an L-shaped plate 10 using screws and nuts. One side of the L-shaped plate 10 has a second fixing hole 9. Two first circular holes are located at the contact points between the ear plate 7 and the U-shaped plate 8. Two second circular holes are located on each of the two parallel sides of the U-shaped plate 8. Two third circular holes are located at the contact points between the L-shaped plate 10 and the U-shaped plate 8. Screws connecting the U-shaped plate 8 and the ear plate 7 pass through the first circular holes and the corresponding second circular holes. Screws connecting two U-shaped plates 8 pass through the two corresponding second circular holes. Screws connecting the U-shaped plate 8 and the L-shaped plate 10 pass through the second circular holes and the corresponding third circular holes. First, using connecting screws 6, the disc 13 is securely fixed within the semi-circular groove 16. During installation, the number of U-shaped plates 8 between the L-shaped plate 10 and the ear plate 7 can be flexibly adjusted according to actual site requirements. Then, the L-shaped plate 10, U-shaped plate 8, and ear plate 7 are sequentially connected using screws and nuts. During this process, as the number of U-shaped plates 8 changes, the distance between the second fixing hole 9 on the L-shaped plate 10 and the base plate 1 will also change accordingly. In this way, the bolts used to limit the position of the base plate 1 can be installed in different positions according to specific circumstances, meeting the requirements of various on-site installation conditions.
