Description

Technical Field

[0001] This application relates to a high-speed socket electrical connector assembly, and particularly to a high-speed socket electrical connector assembly with stable structure and convenient assembly.

Background Art

[0002] Chinese Invention Patent Publication CN101789553B discloses a 2XN high-speed socket electrical connector. This electrical connector includes a housing formed by a first section and a second section. The housing has a hollow interior for filling a set of terminals. The housing also has complementary engaging tracks and channels, so that the two sections can be joined together in a structurally permitted form. However, due to space limitations, this structure has relatively weak strength.

Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a high-speed socket electrical connector assembly with a stable structure.

[0004] To achieve the above object, this application provides a high-speed socket connector assembly for cooperating with an insertion module of a high-speed cable. The high-speed socket connector assembly includes a shielding cage and a plurality of electrical connectors mounted on a circuit board. The shielding cage is provided with upper and lower rows of receiving channels for respectively receiving the aforementioned insertion modules. Each receiving channel has a top wall, a bottom wall and two side walls. The electrical connector includes a housing, a plurality of terminal pieces inserted forward into the housing, and a rear cover covering the rear side of the housing forward. The housing is provided with an upper clamping receiving groove and a lower clamping receiving groove with openings forward. The plurality of terminal pieces are overlapped horizontally and are located in the receiving space formed by the rear cover and the housing. A plurality of snap mechanisms are provided between the rear cover and the housing and are arranged on the first side and the second side opposite to each other in the transverse direction of the electrical connector. Each snap mechanism includes a hook provided on the housing and a buckle provided on the rear cover, and includes an upper snap mechanism at the upper end and a lower snap mechanism at the lower end on the first side in the transverse direction. The arrangement direction of the hook and the corresponding buckle in the cross-section perpendicular to the front-rear direction is the cooperation direction of the corresponding snap mechanism. The cooperation direction of the upper hook mechanism is perpendicular to the cooperation direction of the lower hook mechanism.

[0005] Compared with the prior art, the hook mechanisms with different cooperation directions in this application can prevent the rear cover from retreating compared with the guide rail structure in the prior art, and the guide rail has relatively weak strength and is easy to be damaged. Compared with the snap mechanism with a single cooperation direction of the rear cover, the structure of this application can also ensure the snap stability of the housing and the rear cover in multiple directions.

[0006] As a further design, the rear cover is formed by a conductive material.

[0007] As a further design, the mating direction of the upper snap mechanism is horizontal, and the mating direction of the lower snap mechanism is vertical.

[0008] As a further design, the hook of the upper snap mechanism is disposed inside the corresponding snap base in the horizontal direction, and the hook of the lower snap mechanism is disposed on the lower side of the corresponding snap base.

[0009] As a further design, the same upper snap mechanism and lower snap mechanism are provided on the second side of the electrical connector.

[0010] As a further design, the rear cover is provided with a rear wall and side walls extending forward from the two lateral sides of the rear wall. The rear wall is provided with an opening. Each terminal piece is provided with a rearward convex block, and the convex block is inserted into the opening of the rear wall and is positioned by the opening.

[0011] As a further design, the housing includes two side walls and a top wall. The top wall is provided with a plurality of dovetail grooves extending rearward. Each terminal piece is provided with a corresponding dovetail-shaped slider. The dovetail-shaped slider of each terminal piece is in guiding cooperation with the dovetail groove, facilitating the forward insertion of the terminal piece into the housing.

[0012] As a further design, the high-speed socket connector assembly further includes a plurality of light guide tubes. The plurality of light guide tubes are disposed between the upper receiving channel and the lower receiving channel and extend rearward to both sides of the electrical connector. The light guide tubes are used to guide the optical signals indicating the connection state of the corresponding electrical connector and the insertion module to the front end of the high-speed socket connector assembly.

[0013] As a further design, the rear cover is provided with a vertically extending groove, and the rear end of the light guide tube is received in the vertically extending groove of the rear cover.

[0014] As a further design, the high-speed socket connector assembly further includes a metal shell disposed between the plurality of light guide tubes and the electrical connector. The metal shell is provided with a metal convex bulge. The upper and lower sides of the metal convex bulge are cut open to form a horizontal mating surface, and the mating surface positions the plurality of light guide tubes in the up and down direction.
