When the terminal pin 12 is connected and assembled with the circuit board, because the terminal pin 12 is only limited by the insertion hole 114 of the plastic part 11, the terminal pin 12 is prone to bending deformation during the assembly process, which will reduce the overall assembly speed. The defects that caused the product assembly cost to be too high and easy to short circuit; and the defects presented in the above content are the development engine of this case.

Utility model content

The technical problem to be solved by the utility model is to provide a connector structure to increase assembly efficiency.

In order to solve the above-mentioned technical problems, the utility model allows the plastic parts to be assembled with end pins, and a pressing block is set on the plastic part, and the pressing blocks are provided with slots corresponding to each end pin row, so that the pressing blocks can be used for each end by each slot. Foot positioning, thereby increasing the positioning between the end foot and the plastic part, so that the end foot can be accurately positioned on the plastic part.

After adopting the above structure, the terminal pin of the utility model is not easy to shake, loosen and bend due to external force, and the combination and positioning of the terminal pin and the circuit board can be more accurate and reliable, achieving more stable impedance and better conduction rate The effect is to increase the efficiency of assembly.

Detailed ways

First please refer to FIG. 2, which shows that it is composed of an iron shell 20, a plastic part 30, a plurality of end pins 40 and a pressing block 50, wherein:

The iron shell 20 is an integrally formed member, one end of which is provided with a slot 21, and the opposite groove walls of the slots 21 are respectively formed with semi-cylindrical guide rails 22, and are located on the opposite groove walls of the slot 21 and below the guide rails 22. Each part is bent inwardly to form a buckle 23, and in addition, a second retaining portion 24 is formed outwardly at the lower edge of the opening of the slot 21, and there is a gap between each retaining portion 24;

The plastic part 30 is an integrally formed member, and a guide groove 31 is formed on both sides corresponding to the guide rails 22 of the iron shell 20. In the slot 21, a buckle 32 is respectively provided on the buckles 23 corresponding to the iron shell 20 on both sides of the plastic part 30, and the buckle 23 of the iron shell 20 is fastened and positioned with the buckle holes 32. In addition, the plastic part 30 and the iron The other end of the combination of the shell 20 is provided with a container 33, and the opposite side walls of the container 33 are each formed with a transverse locking recess 34, and a plurality of insertion holes 35 are provided in the container 33 toward the direction of the iron shell 20;

The end pin 40 is an L-shaped metal component, and the longer end is inserted into the insertion hole 35 of the plastic part 30;

The briquetting block 50 is provided with a slot 51 corresponding to the shorter end of each end pin 40. The briquetting block 50 uses the slot 51 for the insertion and positioning of the end pins 40, and the briquetting block 50 is set in the container of the plastic part 30. In the groove 33, two card convex parts 52 are formed on both sides corresponding to the two card concave parts 34 of the plastic part 30, and the pressing block 50 is slidably arranged on the card concave part 34 of the plastic part 30 with the card convex parts 52, and positioned on the plastic part. 30, then the assembler bends the retaining portion 24 of the iron shell 20 so that the retaining portion 24 can be positioned in the limiting groove 53 of the briquetting block 50, and the briquetting block can be moved by the sheet-like retaining portion 24 50 and the plastic part 30 are confined in the slot 21 of the iron shell 20, so as to avoid the backward defect of the pressing block 50 when the end pin 40 inserted by the pressing block 50 is further connected with the circuit board;
