【Detailed ways】

As shown in Figures 2 to 3, the electrical connector 1 of the present invention is used to electrically connect the chip module (not shown) to the circuit board (not shown), which includes a holding frame 11, placed in the holding frame 11 The nearby insulating body 12, and several connecting pieces 13 connecting the holding frame 11 to the circuit board.

The holding frame 11 is generally made of hard material (such as metal). The holding frame 11 includes a main body 110 with a substantially square central opening 111 and a pair of mounting portions 112 extending from the main body 110 . The main body 110 is substantially a rectangular plate-shaped structure. The mounting portions 112 extend outward from a pair of opposite sides of the main body 110 respectively, and the two mounting portions 112 are disposed near corners of the main body 11 and are symmetrical to each other. Each mounting portion 112 is provided with an opening 113 , which is a round hole here, and can also be in other shapes. A plurality of slots 114 are defined around the opening 113 , and the slots 114 are substantially elongated and communicate with the opening 113 . In addition, a plurality of positioning holes 115 are evenly formed on four sides of the main body 110 .

The insulating body 12 is assembled on the holding frame 11 and has a substantially rectangular plate-like structure. A number of conductive terminals (not shown) are accommodated in the insulating body 12. The upper and lower surfaces 120, 121 of the insulating body 12 are respectively connected to the chip module and the holding frame 11. The positioning posts (not shown) are used to cooperate with the positioning holes 115 on the main body 110 of the holding frame 11 , so as to assemble the insulating body 12 to the holding frame 11 . In addition, the insulating body 12 can also be clamped in the middle opening 111 of the holding frame 11 ; it can also be placed in the middle opening 111 and directly welded to the circuit board through the welding part on the conductive terminal.

After the insulating body 12 is combined with the holding frame 11 , the above-mentioned combination is mounted on the circuit board by using the connector 13 . The electrical connector 1 is placed at a predetermined position on the circuit board, the opening 113 is aligned with the corresponding pin hole on the circuit board, and then the connector 13 is passed through the opening 113 and inserted into the pin hole on the circuit board. 13 and the opening 113, and the fit between the connector 13 and the pin hole, the electrical connector 1 is assembled to the circuit board.

In the present utility model, the connecting piece 13 is a cylindrical pin made of a hard material (such as metal), but the connecting piece 13 of the present utility model is not limited to a cylinder, as long as it can use interference fit to connect the electrical connector 1 to The circuit board will do.

Around the opening 113 of the holding frame 11 of the electric connector 1 of the present utility model, there are several slots 114 connected thereto. The range of the amount of interference of the component 13 is larger, therefore, it is easier to control the size, thereby improving the assemblability.
