Description

TECHNICAL FIELD

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

[0002] A kind of electric connector is disclosed in Chinese patent CN202210624516.8, which is a PCIE6.0 connector used to plug electronic cards such as PCIE cards to transmit high-speed signals. The electric connector includes an insulating body, multiple 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 multiple terminal slots that accommodate corresponding terminals one by one, the terminal slots 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 slot and a conductive insertion part inserted into the ground terminal slot. The plug includes a bottom plate, which includes a conductive plate layer and an insulating plate layer connected to each other. The insulating plate layer wraps the upper and lower surfaces of the conductive plate layer. The conductive insertion part is formed by extending upward from the conductive plate layer, and the insulating insertion part is formed by extending upward 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, and then 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 side of the bottom plate is provided with a row of columnar insertion parts, and 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] The above-mentioned electric connector is provided with a row of terminals on each of the two side walls of the slot. The number of terminals cannot be increased, so the signal transmission channel cannot be increased, and the signal transmission speed cannot be greatly improved. The terminal and the plug are of a split type and are installed in the insulating body by plug-in mounting. During assembly, they need to be assembled separately, which requires multiple assembly steps and has a high probability of assembly errors.

[0006] In addition, the Chinese patent CN202110230847.9 discloses a card edge connector, which comprises a longitudinal insulating body, the top surface of the insulating body is recessed in the longitudinal direction to form a central slot, at least one anti-misinsertion block is arranged in the central slot, two accommodation holes are arranged on the two sides of the central slot in the width direction, a conductive terminal is arranged at each accommodation hole, and the accommodation hole penetrates the inner wall surface of the top and bottom surfaces of the insulating body and the side walls on the two sides of the central slot in the width direction. Two towers are arranged at the two ends of the insulating body, and an ear is pivotally connected to each tower. The card edge connector does not have a shielding shell, and cannot shield external interference signals.
