Technical Field

[0001] The present application relates to the technical field of welding auxiliary tools, and in particular to a wiring harness fixing fixture. Background Art

[0002] With the development and progress of electronic technology, there are more and more electronic devices. However, no matter what kind of electronic device it is, its production process is inseparable from the connection between circuit boards and wiring harnesses or electronic components.

[0003] Conventional soldering methods mainly include reflow soldering and wave soldering. Reflow soldering is suitable for SMD components. Wave soldering is suitable for corner components. The connection between the wire harness and the circuit board is usually soldered by wave soldering. The main process includes inserting the end of the wire harness into the mounting hole on the circuit board, and then passing the circuit board over the liquid solder to form a solder joint at the location of the wire harness pin to complete the soldering.

[0004] However, the wiring harness itself is a slender flexible structure, and the end of the wiring harness is prone to skew during the welding process, resulting in poor welding effect between the wiring harness and the circuit board. Utility Model Content

[0012] By adopting the above technical solution, the wiring harness is limited in multiple directions through the limiting groove. On the one hand, it can be convenient for the staff to clamp the wiring harness in the correct position. On the other hand, it can make the two clamping rods fit together, thereby improving the stability of the clamping and limiting components after they are matched.

[0013] Optionally, the limiting groove is arranged in plurality along the length direction of the clamping rod.

[0014] By adopting the above technical solution, a plurality of limiting grooves are provided to facilitate the clamping and limiting components to clamp and limit a plurality of wiring harnesses.

[0015] Optionally, the clamping and limiting components are arranged in multiple groups along a direction parallel to the base plate.

[0018] By adopting the above technical solution, the two clamping rods are limited by two limit blocks, so that the clamping rods can stably clamp the wire harness. The clamping rod can be taken out from between the two limit blocks to separate the two clamping rods, so that the wire harness can be placed between the two clamping rods.

[0019] Optionally, the limiting member further includes an end stopper, which is disposed between two limiting blocks and connected with the limiting blocks to form a U-shaped structure with an opening facing the clamping rod.

[0020] By adopting the above technical solution, the clamping rod is inserted into the U-shaped structure, and the limiting member of the U-shaped structure can limit the displacement of the clamping rod in multiple directions, thereby further improving the stability of the clamping assembly in limiting the wiring harness.

[0021] Optionally, a rotating block is provided on the limiting member, and when the rotating block is rotated, the rotating block can abut against a side of the clamping rod away from the bottom plate.

[0022] By adopting the above technical solution, after the clamping rod clamps the wiring harness, the clamping rod is placed between the two limit blocks in a direction perpendicular to the base plate, and then the rotating block is rotated to make the rotating block abut against the clamping rod, thereby preventing the clamping rod from detaching from between the two limit blocks.

[0023] Optionally, a mounting groove for placing a circuit board is provided on one side of the bottom plate close to the clamping rod.

[0027] The following is combined with Figure 1 This application is described in further detail.

[0028] The embodiment of the present application discloses a fixture for fixing a wiring harness.

[0029] Reference Figure 1 The fixed wiring harness fixture includes a base plate 1 and a clamping and limiting assembly 2. The clamping and limiting assembly 2 is installed on the base plate 1. A gap for placing a circuit board is provided between the clamping and limiting assembly 2 and the base plate 1. The clamping and limiting assembly 2 is used to clamp the end of the wiring harness. One end of the wiring harness is inserted into the mounting hole on the circuit board. At the same time, the clamping and limiting assembly 2 is clamped on the wiring harness to limit the wiring harness, thereby reducing the tilt of the end of the wiring harness. An avoidance hole (not shown in the figure) that passes through the base plate 1 is opened at the position corresponding to the wiring harness on the base plate 1 to facilitate the welding of the wiring harness and the circuit board by wave soldering or other welding methods from the side of the base plate 1 away from the clamping and limiting assembly 2.

[0030] Reference Figure 1The clamping and limiting assembly 2 includes two clamping rods 21, which are arranged parallel to each other, and the wire harness is clamped between the two clamping rods 21. A limiting groove 22 is provided on the side of at least one clamping rod 21 close to the other clamping rod 21, which penetrates in a direction perpendicular to the bottom plate 1. In this embodiment, only one clamping rod 21 is provided with a limiting groove 22, and the wire harness is passed through the limiting groove 22, and the limiting groove 22 can limit the displacement of the wire harness. Not only can the two clamping rods 21 abut against each other, improving the stability of the wire harness limit; but also it is convenient for the staff to clamp the wire harness in a specific position. In other embodiments, limiting grooves 22 can also be provided on the sides of the two clamping rods 21 close to each other. The cross-sectional area of ​​the limiting groove 22 on the plane parallel to the bottom plate 1 corresponds to the cross-sectional area of ​​the wire harness, so as to reduce the occurrence of the wire harness tilting in the limiting groove 22. A plurality of limiting grooves 22 may be provided at intervals along the length direction of the clamping rod 21 , so that the clamping rod 21 assembly can limit the positions of a plurality of wiring harnesses.

[0031] Reference Figure 1 The clamping limit assembly 2 also includes a limit member 23, which includes two limit blocks 231 fixedly connected to the base plate 1, the two limit blocks 231 are arranged at intervals, and the two clamping rods 21 are located between the two limit blocks 231, thereby preventing the two clamping rods 21 from moving away from each other; the clamping rod 21 is moved in a direction perpendicular to the base plate 1, and the clamping rod 21 can be detached from between the two limit blocks 231, making it convenient for the staff to disassemble the wiring harness or clamp the wiring harness again.

[0032] Reference Figure 1 The limiter 23 also includes an end stopper 232, which is arranged on one side of the clamping rod 21 along the length direction of the clamping rod 21, so as to limit the displacement of the clamping rod 21 along its own length direction. The end stopper 232 is located between the two limiter blocks 231. The two limiter blocks 231 and the two parallel side surfaces of the end stopper 232 are connected to form a U-shaped structure with an opening facing the clamping rod 21, which facilitates the installation of the end stopper 232 and the limiter block 231. There are two limiters 23, and the two limiters 23 are respectively arranged at the two ends of the clamping rod 21. On the one hand, it can further improve the stability of the clamping rod 21 in limiting the position of the wire harness, and on the other hand, it can prevent the clamping rod 21 from being displaced along its own length direction from multiple directions.

[0033] Reference Figure 1 The clamping rod 21 assembly can be arranged in multiple groups in a direction parallel to the bottom plate 1, so that the fixture can limit multiple groups of wire harnesses. In this embodiment, the clamping and limiting assembly 2 is arranged in two groups, and in other embodiments, it can be arranged according to the distribution of the wire harness on the circuit board.

[0034] Reference Figure 1, a rotating block 3 is arranged on the side of the limiter 23 away from the bottom plate 1, and the rotating block 3 is rotatably connected to the limiter 23, and the rotation axis of the rotating block 3 is perpendicular to the bottom plate 1. The side of the clamping rod 21 away from the bottom plate 1 is flush with the side of the limiter 23 away from the bottom plate 1, and the side of the rotating block 3 close to the limiter 23 is in contact with the limiter 23. The clamping rod 21 abuts on the side of the rotating block 3 close to the bottom plate 1, thereby preventing the clamping rod 21 from moving in a direction perpendicular to the bottom plate 1. Rotating the rotating block 3 can disengage the rotating block 3 from the clamping rod 21, and the clamping rod 21 can be taken out at this time, so as to facilitate the removal of the circuit board and the wiring harness from the jig. At the same time, before welding, the wiring harness can be placed on the two clamping rod 21 brackets, and then the staff pinches the two clamping rods 21 and places the two clamping rods 21 between the two limiter blocks 231, and finally rotates the rotating block 3 to abut against the clamping rod 21 to fix the circuit board and the wiring harness.

[0035] Reference Figure 1 A mounting groove 4 is provided on the side of the bottom plate 1 close to the clamping and limiting component 2. The circuit board is embedded in the mounting groove 4, and the side of the circuit board can abut against the side wall of the mounting groove 4, so that the displacement of the circuit board can be limited, thereby improving the stability of the circuit board during the wiring harness welding process.

[0036] Reference Figure 1 , a locking block 5 is provided on the bottom plate 1, and the locking block 5 is rotatably connected to the bottom plate 1. After the circuit board is embedded in the mounting groove 4, the locking block 5 is rotated, and the side of the locking block 5 close to the ground can abut against the circuit board, thereby limiting the circuit board and preventing the circuit board from escaping from the mounting groove 4, further improving the stability of the circuit board after being fixed. In order to facilitate the staff to rotate the locking block 5, a handle is welded on the locking block 5 to provide a force point for the staff.
