Description

Technical Field

[0001] This utility model relates to the field of FAKRA wire harness technology, specifically a fixing device for FAKRA wire harnesses. Background Technology

[0002] FAKRA wiring harnesses are standardized radio frequency connection harnesses designed specifically for high-frequency signal transmission in automobiles. They feature high-frequency performance, anti-interference capabilities, miniaturized design, high reliability, standardized interfaces, quick connection and disconnection, and adaptability to harsh automotive environments. They are widely used in automotive wireless communication systems and are evolving towards higher performance, miniaturization, and integration.

[0003] The prior art discloses a wire harness fixing device for wire harness production, with announcement number CN221008656U, belonging to the field of wire harness production technology. It includes a fixing frame with multiple fixing slots evenly spaced on the frame. Each fixing slot has an inner wall with a receiving groove on one side. Hollow slots are provided inside the fixing frame at the top and bottom of each fixing slot. Through slots are provided between two hollow slots and their corresponding receiving grooves. Two sets of moving adjustment mechanisms are installed between the hollow slots and the receiving grooves. Each set of moving adjustment mechanisms includes a lead screw, a moving block, and an adjustment knob. A clamping component is installed at one end of the moving block. Through the cooperation of the lead screw, moving block, and adjustment knob of the moving adjustment mechanism, the clamping component can adjust the tightness of the wire harness fixed in the fixing slots, thereby meeting the requirements of different tightness fixation conditions for the wire harness under different circumstances and satisfying more needs.

[0004] The aforementioned movable block is installed inside the cavity groove, and a clamping assembly is installed at one end of the movable block. After repeated use of the clamping assembly, the compression spring inside the clamping assembly will become fatigued. Fatigue will lead to a decrease in spring stiffness, making it unable to maintain the deformation under the design load. The compression spring needs to be repaired and replaced, which requires disassembling the entire device and replacing the compression spring, which takes a lot of time. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for FAKRA wire harnesses to solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: A fixing device for a FAKRA wire harness includes a clamping device 1 and a threaded rod 2. The clamping device 1 is threaded with fastening bolts 3 at both ends. The threaded rod 2 is inserted into the front and rear ends of the clamping device 1 and is located on the outward side of the clamping device 1.

[0022] The clamping device 1 includes a connecting ear 11, and a rectangular plate 12 is fixedly connected to the back of the connecting ear 11. The rectangular plate 12 is threaded to the front and rear surfaces of the clamp 13.

[0023] The clamp 13 includes a FAKRA wire harness fixing housing 131, a second threaded rod 2 inserted into the front end of the connecting ear 11, the second threaded rod 2 locking and fixing the two FAKRA wire harness fixing housings 131, and determining the position of the FAKRA wire harness fixing housings 131. The second fastening bolt 3 is threaded into the inside of the rectangular plate 12 and threaded into the front and rear ends of the FAKRA wire harness fixing housing 131, the second fastening bolt 3 locking and fixing the rectangular plate 12 and the FAKRA wire harness fixing housing 131, and determining the position of the rectangular plate 12.

[0024] The FAKRA wiring harness fixing housing 131 has a threaded rod 132 fixedly connected to the left and right ends of the inner wall surface. A connecting frame 135 is slidably connected to the inner end of the threaded rod 132. A fixing roller 134 is installed on the inner end of the connecting frame 135. The connecting frame 135 is slidably connected to the surface of the threaded rod 132. The fixing roller 134 slides on the surface of the threaded rod 132 to maintain the stability of the fixing roller 134 and increase the service life of the fixing roller 134.

[0025] A rigid spring 136 is installed on the outer surface of the connecting frame 135. A limit cover 133 is slidably connected to the outer end of the threaded rod 132. The limit cover 133 is movably connected to the outer surface of the rigid spring 136. The rigid spring 136 pushes the connecting frame 135 to move inward. The restoring force of the rigid spring 136 can be converted into a clamping force on the wire harness.

[0026] The upper and lower ends of the limiting cover 133 are threaded with fastening bolts 137. The limiting cover 133 is movably connected to the left and right sides of the FAKRA wire harness fixing housing 131. The fastening bolts 137 limit the limiting cover 133, making it easy to disassemble and replace the limiting cover 133, thus making the maintenance of the rigid spring 136 more convenient. The fastening bolts 137 are bolted to the left and right ends of the FAKRA wire harness fixing housing 131, and the fastening bolts 137 lock the FAKRA wire harness fixing housing 131 and the limiting cover 133 together.

[0027] When in use, rotate the fastening bolt 137 outward to disengage the fastening bolt 137 from the FAKRA wire harness fixing housing 131 and the limiting cover 133, thereby loosening the connection between the FAKRA wire harness fixing housing 131 and the limiting cover 133.

[0028] Pull the limiting cover 133 outward to detach it from the FAKRA wire harness fixing housing 131. Then pull the rigid spring 136 outward to move it outward, causing the rigid spring 136 to drive the connecting frame 135 outward, which in turn drives the fixing roller 134 outward.

[0029] This allows the fixed roller 134, connecting frame 135, and rigid spring 136 to detach from the FAKRA wiring harness fixing housing 131, facilitating maintenance of the fixed roller 134, connecting frame 135, and rigid spring 136.

[0030] The FAKRA harness is inserted into the middle position of the FAKRA harness fixing housing 131. The FAKRA harness fixing housing 131 can push the fixing roller 134 to move left and right inside the FAKRA harness fixing housing 131. The FAKRA harness fixing housing 131 pushes the connecting frame 135 to move left and right inside the FAKRA harness fixing housing 131.

[0031] When the connecting frame 135 moves inside the FAKRA harness fixing housing 131, the connecting frame 135 slides on the surface of the threaded rod 132, and at the same time, the rigid spring 136 can be compressed between the limiting cover 133 and the connecting frame 135.

[0032] After the FAKRA harness reaches the appropriate position inside the FAKRA harness fixing housing 131, the rigid spring 136 begins to rebound. The rigid spring 136 pushes the connecting frame 135 to move outward, causing the connecting frame 135 to push the fixing roller 134 to move inward. Then, the fixing roller 134 clamps and fixes the FAKRA harness, maintaining the stability of the FAKRA harness.

[0033] 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 the 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.
