[0001] This utility model belongs to the field of connector technology, and particularly relates to a standard terminal connector. Background Technology

[0002] Terminal connectors are a common type of electronic connector, widely used in data acquisition instruments, PCB board connections, modular equipment, and other fields. The existing processing steps include: (1) terminal forming, which involves stamping several independent terminals; (2) injection molding of the housing, which involves placing several terminals one by one into a mold to form a hollow housing with terminals; and (3) terminal bending, which involves bending the terminals with a bending tool to bend them relative to the hollow housing to form terminals that can be inserted into the circuit board. However, this processing method has the following drawbacks: limited operating space in the mold, low placement efficiency, narrow gap between the formed insertion section and the hollow housing, and the bending tool is prone to breakage due to being too thin. Utility Model Content

[0003] The purpose of this invention is to provide a target terminal connector, which aims to solve the technical problems in the prior art.

[0004] To achieve the above objectives, the present invention provides a target terminal connector comprising a hollow housing, a plurality of targets, and an assembly. The hollow housing has a cavity with a rear end opening, and a plurality of first through holes are provided at the front end of the cavity. One end of each target passes through the first through hole and is bent outside the hollow housing to form a plug-in section. The other end of each target is fixed inside the hollow housing by the assembly and forms a wiring section. The hollow housing has a triangular groove recessed inward at one end near the plug-in section.

[0005] Optionally, the groove includes a slot corresponding to a plurality of the insertion segments, and a partition plate is provided between adjacent slots.

[0006] Optionally, the assembly has a second through hole that corresponds one-to-one with the wiring segment.

[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, a connector for terminal 2 is provided, including a hollow housing 1, a plurality of terminals 2 and an assembly 3. The hollow housing 1 has a cavity 11 with a rear opening. The front end of the cavity 11 is provided with a plurality of first through holes 12. One end of each terminal 2 passes through the first through hole 12 and is bent outside the hollow housing 1 to form a plug section 21. The other end of each terminal 2 is fixed inside the hollow housing 1 by the assembly 3 and forms a wiring section 22. The hollow housing 1 has a triangular groove 13 recessed inward at one end near the plug section 21. First, several guides 2 are installed and fixed on the assembly 3. Then, the assembly 3 with guides 2 is placed into the injection mold and a semi-finished product is obtained by injection molding. Finally, the guides 2 are bent by the bending mold to form the insertion section 21. This application uses the assembly 3 to assemble several guides 2 outside the mold, which reduces the difficulty of placing the guides 2 and helps to improve production efficiency. By using the triangular groove 13, the gap between the insertion section 21 and the hollow shell 1 is increased. Triangular reinforcing ribs can be processed on the inner side of the bending tool, thereby reducing the breakage caused by the bending tool being too thin and helping to improve the service life of the bending tool.

[0029] In one embodiment of this utility model, such as Figures 1-2 As shown, the groove 13 includes slots corresponding one-to-one with a plurality of the insertion segments 21, and partition plates 14 are provided between adjacent slots. Specifically, a pair of adjacent partition plates 14 are used to form a gap for the insertion of the triangular reinforcing ribs of the cutting tool, so as to achieve the positioning effect of the bending tool.

[0030] In one embodiment of this utility model, such as Figure 3 As shown, the assembly 3 has a second through hole 31 that corresponds one-to-one with the wiring segment 22. Specifically, the second through hole 31 is rectangular in shape, and the guide 2 is interference-fitted with the second through hole 31.

[0031] In one embodiment of this utility model, such as Figure 3As shown, a first reinforcing piece 23 extends outward from the left side of the guide 2. The first reinforcing piece 23 includes a first horizontal section 231 and a first vertical section 232 connected together. A first slot is provided on the left side of the second through hole 31 for the first horizontal section 231 to be inserted. The first vertical section 232 is bent upward, with one side abutting against the inner cavity of the hollow shell 1 and the other side abutting against the fitting 3. Specifically, by using the first vertical section 232 to abut against the inner wall of the hollow shell 1, a limiting force is provided for the guide 2 in its axial direction, which helps to reduce the possibility of the guide 2 falling off. The insertion and cooperation of the first horizontal section 231 with the first slot further improves the stability of the guide 2 and the fitting 3.

[0032] In one embodiment of this utility model, such as Figure 3 As shown, a second reinforcing piece 24 extends outward from the right side of the guide 2. The second reinforcing piece 24 includes a connected second horizontal section and a second vertical section. A second slot is provided on the right side of the second through hole 31 for the second horizontal section to be inserted. The second vertical section is bent downward, with one side abutting against the inner cavity of the hollow shell 1 and the other side abutting against the fitting 3. Specifically, by using the second vertical section to abut against the inner wall of the hollow shell 1, a limiting force is provided for the guide 2 in its axial direction, which helps to reduce the possibility of the guide 2 falling off. The insertion and cooperation of the second horizontal section with the second slot further improves the stability of the guide 2 and the fitting 3.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, a guide strip 111 protrudes from the inner top wall of the hollow housing 1 along the insertion / removal direction of the assembly 3, and a guide groove 32 is formed on the top of the assembly 3 to slide and engage with the guide strip 111. The engagement of the guide strip 111 and the guide groove 32 improves the stability of the assembly 3 during installation within the hollow housing 1.

[0034] In one embodiment of this utility model, such as Figure 3 As shown, the wiring segment 22 has a protrusion structure 25 at the mating point with the first through hole 12. Specifically, the protrusion structure 25 is a rectangular protrusion on both sides of the wiring segment 22, which increases the contact area between the guide pin 2 and the first through hole 12, and helps to improve the fixing effect of the guide pin 2.

[0035] In one embodiment of this utility model, such as Figure 2 As shown, the top of the hollow housing 1 is provided with a positioning post 15. Specifically, the PCB board has positioning holes corresponding to the positioning post 15. When the plug section 21 is inserted into the PCB board, the positioning post 15 and the positioning hole are used to achieve the positioning effect of the hollow housing 1 on the PCB board.
