Abstract
Description
Technical Field
[0001] The utility model relates to a positioning module, in particular to a positioning module for blindly threading a conductor. Background Art
[0002] With the continuous development of electrical connection technology, various application fields have increasingly strong requirements for the miniaturization of electrical connectors. In the field of molded crimping connection technology for ultra-micro connectors and 30AWG wires, since the outer diameter of the wire is only 0.61mm and the outer diameter of the core wire is only 0.30mm, it is difficult for the core wire of the wire to smoothly pass through the open crimping barrel at the tail of the contact and be in place. At present, through manual threading, it is easy for 1-2 strands of multi-strand core wires to fail to pass through the crimping barrel, resulting in the inability to guarantee the tensile strength of the crimping and easily causing short circuits after assembly. Therefore, the development of a positioning module for blind threading of wires to ensure that the wires pass smoothly and accurately into the crimping barrel has become a problem that needs to be solved by technical personnel in this field. Utility Model Content
[0003] The utility model is to solve the above-mentioned shortcomings and provides a positioning module for blind wire passing.
[0004] The above-mentioned purpose of the utility model is achieved through the following technical scheme: a positioning module for blind threading of wires, including an online threading positioning piece and an offline threading upper positioning piece, wherein the online threading positioning piece has an inclined semicircular hole on the lower right side and an upper hole chamfer; the offline threading positioning piece has a 1 / 4 arc hole and a hole chamfer on the upper right side, and a threading channel is formed when the online threading positioning piece is closed.
[0005] Furthermore, the online threading positioning piece is connected to the offline threading positioning piece through a hexagon socket screw, the online threading positioning piece and the offline threading positioning piece are positioned and guided by a guide positioning pin and a guide positioning groove, and a compression spring is provided between the online threading positioning piece and the offline threading positioning piece.
[0006] Furthermore, a limiting rib is provided at the bottom of the threading lower positioning piece.
[0007] Furthermore, a material belt protection tooth avoidance groove is provided at the bottom of the threading lower positioning piece.
[0008] Compared with the prior art, the utility model has the following advantages: the original manual threading method is used, and it is easy for 1-2 strands of core wires to fail to penetrate into the crimping barrel, resulting in the inability to ensure the tensile strength of the crimping and the possibility of short circuit after assembly. The utility model forms a threading channel by closing the upper and lower threading positioning pieces, and the core wire of the conductor can easily pass through the threading channel to smoothly and accurately penetrate into the crimping barrel, which can well ensure that the core wire is not exposed to ensure the tensile strength of the crimping. Not only the electrical performance of the crimping is guaranteed, but also the risk of short circuit between adjacent contacts after the insulator of the connector is installed is avoided.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0020] like Figures 1 to 6 As shown, a blind wire positioning module includes an upper threading positioning member 2 and an upper threading positioning member 1. The lower right side of the upper threading positioning member 2 has an inclined semicircular hole 201 and an upper hole chamfer 202; the upper right side of the lower threading positioning member 1 is correspondingly provided with a 1 / 4 arc hole 101 and a hole chamfer 102, and a threading channel A is formed when the upper threading positioning member is closed. The upper threading positioning member 2 is connected to the lower threading positioning member 1 through a hexagon socket screw 5, and the upper threading positioning member 2 and the lower threading positioning member 1 are positioned and guided by a guide positioning pin 3 and a guide positioning groove 9, and a compression spring 4 is provided between the upper threading positioning member 2 and the lower threading positioning member 1. The bottom of the lower threading positioning member 1 is provided with a limiting rib 103 and a material belt protection tooth avoidance groove 102.
[0021] The working principle of the "blind wire" in this utility model:
[0022] like Figure 7 , Figure 8 and Fig.10 As shown, the blind threading wire positioning module C of the utility model is first fixed on the wire crimping machine 7, and the limiting rib 103 of the positioning module is inserted into the limiting groove of the wire crimping machine 7 to ensure that the core wire 601 of the wire 6 is aligned with the opening of the contact crimping barrel 802 of the material strip 8. The protective tooth 801 of the material strip 8 is inserted into the avoidance groove 102 of the threading positioning member 1. The threading positioning member 2 is pressed down and closed with the threading positioning member 1 to form a threading channel A, and the wire 6 is inserted from A to the chamfered threading channel A until the core wire 601 is smoothly inserted into the contact crimping barrel 802. The punch 701 is pressed down to complete the crimping of the wire 6 and the contact crimping tube 802; the threading positioning piece 2 is released, and the compression spring 4 lifts the right side wire protection edge 203 of the threading positioning piece 2 upward to form a certain gap, ensuring that the wire 6 moves together when the material strip 8 moves forward to avoid the wire 6 being blocked; at this time, a working cycle of blind threading (and crimping) of the wire is completed.
