Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of connector, concretely relates to a high speed high density communication storage electric connector. BACKGROUND

[0002] Chinese patent CN202210624516.8 discloses an electric connector, which is a PCIE6.0 connector used for inserting electronic cards such as PCIE cards to transmit high-speed signals. The electric connector includes an insulating body, a plurality of terminals and a plug. The insulating body is provided with a mating surface, a slot formed by recessing from the mating surface, a slot bottom surface facing the mating surface, and two inner wall surfaces connecting the mating surface and the slot bottom surface. The top surface of the insulating body constitutes the mating surface, and the electronic card is inserted into the slot through the mating surface. The insulating body includes two side walls located on both sides of the slot, each side wall is provided with a plurality of terminal grooves for accommodating corresponding terminals, the terminal grooves penetrate downward, inwardly penetrate the inner wall surface, and upwardly penetrate the mating surface.

[0003] The terminal includes a fixed part, an elastic arm and a pin part.

[0004] The plug is of an integrated structure and is installed on the insulating body. The plug includes an insulating insertion part inserted into the signal terminal groove and a conductive insertion part inserted into the ground terminal groove. The plug includes a bottom plate including a conductive plate layer and an insulating plate layer connected to each other. The insulating plate layer is wrapped on the upper and lower surfaces of the conductive plate layer. The conductive insertion part is formed by extending upwardly from the conductive plate layer. The insulating insertion part is formed by extending upwardly from the insulating plate layer. The conductive insertion part is made of conductive plastic material. The conductive plate layer and the conductive insertion part are formed by first injection molding. The insulating plate layer and the insulating insertion part are formed on the upper and lower surfaces of the conductive plate layer by second injection molding, thereby forming the plug of an integrated structure. The conductive insertion part and the insulating insertion part are both columnar insertion parts. Each of the two sides of the bottom plate is provided with a row of columnar insertion parts. Each row of columnar insertion parts extends in the longitudinal direction. The columnar insertion part abuts against the holding part of the terminal in the upper half close to the slot bottom surface, and is spaced apart from the terminal by a certain distance in the lower half away from the slot bottom surface. The interference between the columnar insertion part and the insulating body increases the holding force of the plug and the insulating body.

[0005] A row of terminals is arranged on each of the two side walls of the slot of the electric connector. The number of terminals cannot be increased, so the signal transmission channel cannot be increased, and the signal transmission speed cannot be greatly improved. Moreover, the terminal and the plug are of a split structure and are installed in the insulating body by insertion. The assembly needs to be inserted separately, and the probability of assembly error is high. Therefore, improvement is needed. UTILITY MODEL CONTENTS
