In conclusion, the electrical connector of the present invention has the following beneficial effects.
(1) According to the electrical connector of the present invention, the carrying member 2 is directly pivoted to the insulating body 1, specifically, each of the two ends of the pivoting side of the carrying member 2 is provided with a pivot shaft, the fixing holes 12 are formed at an outer side of the insulating body 1, and the pivot shafts are pivoted into the fixing holes 12. In this way, the carrying member 2 is rotatingly pivoted to the insulating body 1 without the assistance of any pivoting device for pivoting the carrying member 2. The structure of the electrical connector is simplified, the electrical connector can be assembled more easily, assembly efficiency is improved, and cost is saved at the same time.
(2) According to the electrical connector of the present invention, the carrying member 2 and the pressing plate 3 are arranged on two adjacent peripheral sides of the insulating body 1. Compared with a mode that the carrying member 2 and the pressing plate 3 are arranged on the same side or opposite sides of the insulating body 1, there is no need to increase the length of the electrical connector of the present invention, so that the electrical connector occupies less space of a circuit board, the space of the circuit board is saved, and therefore the electrical connector is suitable for the current miniaturization tendency of electronic products.
(3) By taking one long side of the carrying member 2 as the pivoting side, the center of gravity of the carrying member 2 is lowered. When the carrying member 2 carries the chip module 8 to conduct downward pressing, the downward pressing force of the carrying member 2 is reduced. It ensures that the buffer portion 55 has enough buffering force to buffer the downward pressing force of the carrying member 2, a situation that the carrying member 2 carrying the chip module 8 directly falls onto the terminals 11 on the insulating body 1 is avoided, and the risk of misoperation is reduced.
(4) Each of the two ends of the pivoting side of the carrying member 2 is provided with a pivot shaft, the pivot shafts are pivoted into the fixing holes 12, and pivoting of the carrying member 2 can be achieved without any other pivoting component, so that the electrical connector can be assembled more easily and cost can be reduced.
(5) A buffer portion 55 extends upwards from each second elastic portion 54, the buffer portion 55 is located between the insulating body 1 and the carrying member 2, and the carrying member 2 is concavely provided with the engaging portion 22 corresponding to the buffer portion 55. When the carrying member 2 pivots to the insulating body 1, the engaging portion 22 abuts against the buffer portion 55, the buffer portion 55 applies a buffering force to the carrying member 2 to reduce the downward pressing force of the carrying member 2, so that the carrying member 2 stops moving, a situation that the carrying member 2 carrying the chip module 8 directly falls onto the terminals 11 on the insulating body 1 is avoided, and the risk of misoperation is reduced. And meanwhile, the buffer portion 55 stops the carrying member 2 from moving leftwards and rightwards, so that downward pressing accuracy of the carrying member 2 is ensured.
(6) The main body portion 51 is provided with the multiple soldering portions 57, the soldering portions 57 fix the main body portion 51 to the base 4, fixation is steadier through laser soldering, no solder is needed, usage of other fixing structures is avoided at the same time, and soldering is more convenient.
(7) The side of the carrying member 2 opposite to the pivoting side is provided with two first guide portions 23. The two short sides of the carrying member 2 are provided with the second guide portions 24, respectively, each of the first guide portions 23 and the second guide portions 24 is provided with a chamfer, the first guide portions 23 and the second guide portions 24 are engaged with the outer wall of the insulating body 1 to guide the carrying member 2 to move downwards to the insulating body 1, so that engaging is more convenient and positioning is more accurate when the carrying member 2 pivots to the insulating body 1.
(8) In the closed state, when the pressing plate 3 presses the carrying member 2 or the chip module 8, elastic deformation of the first elastic portion 53 occurs under stress; when the electrical connector is opened, the carrying member 2 or the chip module 8 is not pressed by the pressing plate 3, the first elastic portion 53 springs back to the state before being pressed, namely the buffered state, so that the chip module 8 is moved out of the insulating body 1 without damaging the terminals 11 on the insulating body 1.
