【Background technique】

Electrical connectors are widely used in computers, consumer electronics and other electronic equipment to connect other electronic components. U.S. Patent No. 6,971,902 discloses an electrical connector mounted on a circuit board for connecting a chip component, which includes an insulating body containing a number of conductive terminals, metal sheets framed around the body, and respectively rotatably connected Pressure rods and glands at opposite ends of the metal sheet. When the chip component is placed on the insulating body, rotate the gland to press it on the chip component, and then turn the pressure rod to buckle the end of the gland, and the hand-held end of the pressure rod can be buckled on the corresponding part of the metal sheet, and then the Chip components are securely mounted in the connector. The connecting part of the metal sheet and the pressing bar is bent to form a "C" shaped limiting piece, which limits the pressing bar from above the pressing bar. Although this structure can realize the limit of the pressure rod, its structural strength is poor, especially when the pressure rod buckles the gland, it will give the limit piece a lot of resistance, which may cause the limit piece to deform, and even cause The pressure rod came off the sheet metal, causing damage to the electrical connector.

【Detailed ways】

1 to 3 of the present utility model, the electrical connector 1 is assembled on a circuit board 2 to connect a chip component 3, which includes an insulating body 4 for carrying the chip component 3, and is framed on the outside of the insulating body 4. The surrounding fixing parts 5, and the pressing rods 6 and glands 7 which are respectively rotatably connected to the opposite ends of the fixing part 5. A plurality of conductive terminals 40 are disposed in the insulating body 4 to achieve electrical connection with the circuit board 2 and the chip component 3 .

The fixing part 5 is a frame-like structure and surrounds the insulating body 4 around. Each of its two ends is provided with a pair of limiting pieces 50 formed by drawing upwards from the fixing member 5 . The limiting piece 50 includes a horizontal upper blocking portion 500 and connecting portions 51 extending downward on both sides of the upper blocking portion 500 and connected to the fixing member 5 . Since the limiting sheet 50 is drawn, a closed limiting hole 502 is formed between it and the fixing member 5 . A mounting hole 503 is defined on the upper blocking portion 500 , and a bolt 53 passes through the mounting hole 503 to fix the fixing member 5 to the circuit board 2 . The two limiting pieces 50 at one end of the fixing member 5 are used to connect the pressing bar 6 , and the fixing member 5 is bent upwards between the two limiting pieces 50 at the other end to form a connecting portion 51 with a connecting hole 510 thereon. In addition, the fixing part 5 can also be set as a separate type, that is, the pressure bar and the gland are respectively connected to an independent fixing part located at two ends outside the insulating body.

The pressing rod 6 is substantially "L" shaped and includes a rotating shaft portion 60 and an operating portion 61 . A buckling part 62 is provided in the middle of the shaft part 60, and the shaft part 60 is divided into two sections, and the two sections of the shaft part 60 are respectively inserted into the corresponding limiting holes 502, so that the pressing rod 6 is rotatably mounted on the fixing member 5 on. At the same time, the bolt 53 in the limiting hole 502 can further constrain the rotating shaft portion 60 of the pressure rod 6 to prevent it from shaking in the limiting hole 502 . The end of the operation part 61 is reversely bent to form a handle part 63 for the user to operate. The gland 7 is roughly in a frame structure, and its opposite front and rear ends are respectively provided with a tongue 71 and a pair of arc-shaped hooks 70. The hooks 70 cooperate with the connecting holes 510 of the connecting part 51 on the fixing part 5 to realize The gland 7 is rotatably installed on the fixing member 5 .

After the chip component 3 is placed on the insulating body 4, turn the pressing cover 7 to press it on the chip component 3, then turn the pressing rod 6 so that the buckle 62 presses the tongue 71 at the end of the pressing cover 7, and at the same time press the rod The end of the operating portion 61 of 6 is buckled on a buckle 52 provided at a corresponding position on the fixing member 5 . Since then, the chip component 3 has been stably and reliably installed in the electrical connector 1 . The above is the preferred implementation mode of the present invention for buckling the chip component. In addition, it can also be directly buckled on the chip component through the pressing rod, and the gland structure is omitted.

When the pressing rod 6 buckles the pressing cover 7 , it will exert a relatively large force on the limiting piece 50 . Since the limiting piece 50 of the present invention is formed by drawing directly from the fixing member 5 , the limiting piece 50 has a high structural strength and will not be easily deformed by the force of the pressing rod 6 . At the same time, due to the existence of the closed limiting hole 502 , the pressing rod 6 will not fall off from the fixing member 5 .
