Electric connector and manufacturing method thereof

Abstract

The invention provides an electric connector. The electric connector comprises an insulation body, a first row of conductive terminals, a second row of conductive terminals, and a metal sheet. Each row of conductive terminals comprises a grounding terminal located at the outer side, a power terminal located at the inner side and a plurality of secondary terminals, the insulation body comprises a first insulation body, a second insulation body and a third insulation body which is subjected to injection moulding at the outer portions of the first insulation body and the second insulation body, each row of conductive terminals comprises a main body portion moulded in the insulation body and a welding portion extended backwards from the main body portion, the main body portion is provided witha head extended out of the first insulation body and the second insulation body forwards, the main body portions of the rows of conductive terminals are connected through material straps arranged atthe front end of the heads prior to moulding of the rows of the conductive terminals at the insulation body, and the head portions of the power terminals of the rows of conductive terminals are punched in an opposite direction so that the head portions of the power terminals of the two rows of conductive terminals which are injection moulding behind the insulation body are abutted against each other prior to injection moulding of the two rows of conductive terminals in the insulation body.

Description

[0001] 【Technical Field】 [0002] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector suitable for positive and negative insertion. [0003] 【Background technique】 [0004] In the prior art, the Type C socket connector includes an insulating body, two rows of conductive terminals injection molded into the insulating body, and a metal sheet clamped between the two rows of conductive terminals. In order to make the socket connector transmit large currents, Each terminal head of each row of conductive terminals is punched once, and then the heads of the power terminals of the two rows of conductive terminals are further punched twice so that the heads of the power terminals of the two rows of conductive terminals after being formed abut each other in the up and down direction. In order to facilitate the stamping and forming of the heads of each row of terminals, the terminals of each row of conductive terminals ar...

Problems solved by technology

[0004] In the prior art, the Type C socket connector includes an insulating body, two rows of conductive terminals injection-molded in the insulating body, and a metal sheet clamped between the two rows of conductive terminals. Each terminal head of each row of conductive terminals is punched once, and then the heads of the power terminals of the two rows of conductive terminals are further punched twice so that the heads of the power terminals of the two rows of conductive terminals after forming are against each other in the up and down direction. In order to facilitate the stamping of the heads of each row of terminals, the terminals of each row of conductive terminals are connected through material bridges, but after injection molding each row of terminals into the insulating body, it is necessary to cut off each terminal one by one. The material bridge connected between them, this method is relatively cumbersome, and the manufacturing process is more complicated
