Description

Universal Serial Bus connector

technical field

The utility model relates to a universal serial bus connector, in particular to a side vertical universal serial bus connector.

Background technique

Commonly used USB connectors are mostly flat and horizontal, with relatively large upper and lower areas, and thus need to occupy a large space on the circuit board during assembly, which is not conducive to the miniaturization of the circuit board. Therefore, a side-standing universal serial bus connector has appeared. The current side-standing universal serial bus connector generally includes an insulating seat, several terminals fixed on the insulating seat and a shell covered outside the insulating seat. The seat has a vertically elongated plate body, the middle part of the front surface of the plate body protrudes forward with a vertical plate-shaped insertion part, and there are several rearward extending parts on the two sides of the insertion part. And the rear end is in the slot extending downward on the board body. The terminals all have a vertical plate-shaped holding part, a contact part extending forward from the upper end of the holding part, and a welding part extending downward from the lower end of the holding part. The terminals are divided into two groups and assembled on both sides of the insulating seat respectively. The parts protrude from the side of the shell with a small area in two rows, and are inserted and welded on the circuit board to reduce the space occupied when assembling with the circuit board and achieve the purpose of miniaturization.

However, since the commonly used side vertical USB connector is inserted on the insulating seat, and the terminals are divided into two groups and assembled on both sides of the insulating seat, there is an assembly gap between the terminal and the insulating seat. It is easy to loosen when it is docked with the butt connector, and the welding part protrudes from the side of the shell with a small area in two rows and is inserted and welded on the circuit board. The assembly area with the circuit board is small, so it is easy to integrate with the circuit board. There is looseness between the boards and the connection is not stable.

The first insulating base has a vertically elongated first plate body, and a vertical plate-shaped insertion portion protrudes forward from the middle of the front surface of the first plate body. Wherein each first terminal includes a vertical strip-shaped first welding portion, wherein each second terminal includes a vertical strip-shaped second welding portion, and the first welding portion protrudes from the bottom of the first insulating seat On the surface, the second welding part protrudes from the lower surface of the second insulating seat, and the first welding part and the second welding part protrude below the shell in two rows.
