[0002] The purpose of threading the terminal wire through the flat mesh tube is to provide protection for the wire harness. The existing method of threading the flat mesh tube mainly relies on manual operation. It is necessary to manually expand the port of the flat mesh first, and the mesh needs to be dragged while threading the wires, which is inefficient. Moreover, in the process of threading the flat tube mesh, the terminal may be deformed and foreign matter may enter the terminal hole, resulting in poor electrical performance of the terminal. In view of the above situation, it is urgently necessary to provide a handheld syringe jig for quickly threading the flat mesh tube. Utility Model Content

[0007] Adhesive tape is fixed to the tail end of the syringe and is used to fix the wiring harness wires.

[0008] Preferably, the main body of the needle is in the shape of a long rod, and a tapered portion is formed by the head end of the needle.

[0009] Preferably, the barrel portion of the syringe tapers gradually along one end and is integrally connected with a joint portion, which is detachably connected to the needle.

[0010] Preferably, the needle and the joint portion of the syringe are matched and connected via a threaded structure.

[0011] Preferably, a U-shaped limiting structure extends from the other end of the barrel portion of the syringe, and the adhesive tape is fixed on the U-shaped limiting structure.

[0012] Preferably, the U-shaped limiting structure has a support arm distributed in a U shape, a notch is formed on one side of the support arm, and the adhesive tape is wrapped around and fixed on the support arm through the notch.

[0013] The utility model discloses a hand-held syringe fixture for fast threading of flat mesh tubes, which can quickly locate and thread the wires with the needle as a guide, solving the problem of low efficiency of the existing manual threading of flat mesh tubes. At the same time, the syringe provides protection performance, avoiding damage to the terminal during the threading of the flat tube and the problem of foreign matter entering the terminal hole, ensuring stable and reliable electrical performance of the terminal, and reducing the electrical performance failure rate of the wiring harness.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The utility model discloses a hand-held syringe fixture for quickly inserting a flat mesh tube, which is a new tool designed to solve the operational drawbacks of the existing terminal line inserting a flat mesh tube. Figure 1 and Figure 2 As shown, it mainly includes three parts: a needle 1, a syringe 2, and an adhesive tape 3;

[0020] The needle 1 is located at the head end of the handheld syringe fixture, and the main body is in the shape of a long rod. The tapered portion is formed by the head end of the needle 1, which can more easily pass through the flat mesh tube.

[0021] The syringe 2 is located at the rear side of the needle 1 and is detachably connected to the needle 1. Specifically, the barrel 21 of the syringe 2 gradually tapers along one end and is integrally connected with a joint 22, and the joint 22 is detachably connected to the needle 1 through a threaded structure 5. The needle 1 and the syringe 2 are connected through a threaded structure, which is convenient for disassembly and can be adapted to syringes of different specifications; for different terminals, only the syringe of the corresponding specification needs to be replaced, which is convenient for replacement and has the advantage of reducing the cost of the fixture.

[0022] When the terminal harness 6 is passed through the flat tube, the syringe 2 provides a location for inserting the harness terminal, thereby protecting the terminal inserted therein.

[0023] At the same time, the adhesive tape 3 is fixed to the rear end of the syringe 2 and is used to fix the wire harness conductor after the wire harness terminal is placed in the syringe 2.

[0024] Specifically, a U-shaped limiting structure 4 is extended from the other end of the barrel portion 21 of the syringe 2, and the adhesive tape 3 is fixed on the U-shaped limiting structure 4. Figure 3 As shown, the U-shaped limiting structure 4 has a U-shaped support arm 4a, and a notch 4b is formed on one side of the support arm 4a. After passing through the notch 4b, the adhesive tape 3 can be wrapped and fixed on the support arm 4a, thereby fixing the adhesive tape 3 on the U-shaped limiting structure 4.

[0025] The adhesive tape 3 is fixed by adhesive to limit the wiring harness, preventing the terminal from coming out of the syringe during the process of passing through the flat mesh tube. After the terminal wiring harness 6 passes through the flat mesh tube, the terminal wire can be taken out of the syringe by simply opening the adhesive tape, which is convenient and quick.

[0026] In summary, for the handheld syringe jig for quickly inserting a flat mesh tube disclosed by the utility model, the head and the syringe are connected by a threaded structure, which is convenient for disassembly and can be adapted to syringes of different specifications, thereby meeting the use requirements of different specifications of terminal harnesses passing through flat tubes. The shape structure of the head end of the needle is conical, which can be more easily passed through the flat mesh tube, improving work efficiency. The syringe protects the terminal from damage during the tube insertion process, ensures the stable and reliable electrical performance of the terminal, and reduces the electrical performance failure rate of the harness.

[0027] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
