Electrical connectors

Abstract

This invention relates to an electrical connector, which has a mating space inside an insulating base. A plurality of signal terminals of a mating terminal group have mating sides extending into the mating space on one side and fixed sides extending outwards from the insulating base on the other side. Furthermore, the first and second upper and lower rows of power terminals of the first and second mating terminal groups have mating sides extending into the mating space on one side and fixed sides extending outwards from the insulating base on the other side. Waterproof portions are provided on the multiple fixed sides, multiple first upper and lower row fixed sides, and multiple second upper and lower row fixed sides, respectively, located inside the mating space of the insulating base, thereby achieving a good waterproof effect for the electrical connector.

Claims

1. An electrical connector comprising an insulating base and a mating terminal assembly passing through the insulating base, wherein: The insulating base has a mating space inside. The mating terminal assembly includes a plurality of mating signal terminals, a first mating power terminal portion and a second mating power terminal portion located outside the plurality of mating signal terminals, so that each mating side of the plurality of mating signal terminals on one side extends into the mating space, and each fixed side on the other side extends outward from the insulating base. The first mating power terminal portion includes two opposing first upper row terminals and a first lower row terminals. Each first upper row mating side of the first upper row terminals and each first lower row mating side of the first lower row terminals on one side extends into the mating space. Each first upper row fixed side of the first upper row terminals and each first lower row fixed side of the first lower row terminals on the other side... The fixed sides of the two terminals extend to the outside of the insulating base, and the second docking power terminal part includes two opposing second upper row terminals and second lower row terminals. The second upper row docking side on one side of the second upper row terminal and the second lower row docking side on one side of the second lower row terminal extend to the docking space. The second upper row fixing side on the other side of the second upper row terminal and the second lower row fixing side on the other side of the second lower row terminal extend to the outside of the insulating base. Waterproof parts are provided on the inner side of the docking space of the insulating base on the plurality of fixing sides, the plurality of first upper row fixing sides, the plurality of first lower row fixing sides, the plurality of second upper row fixing sides, and the plurality of second lower row fixing sides.

2. The electrical connector as described in claim 1, wherein the insulating base of the electrical connector includes a first base and a second base, and the first base includes a body and a connecting body extending outward from one side of the body. The connecting body has protrusions spaced apart and waterproof rings fitted on its surface, and an assembly groove for assembling the second base is recessed inside the body and the connecting body. A connecting side for assembly at the assembly groove is provided on one side of the second base, and the waterproof part is provided between the outside of the connecting side and the inside of the assembly groove. A shielding shell is covered on the outside of the second base, and a through-type mating space is provided inside the second base.

3. The electrical connector as claimed in claim 2, wherein the electrical connector is a waterproof liner of the waterproof part, which is an insulating material that is cured and molded through potting, between the outer side of the connection side on the second base side of the insulating base and the inner side of the assembly groove of the first base.

4. The electrical connector as claimed in claim 1, wherein the plurality of mating signal terminals of the electrical connector comprises a frame in the shape of an 1, and each frame has two opposing bent mating sides extending in the same direction on one side and a fixing side extending horizontally on the other side.

5. The electrical connector as described in claim 1, wherein the first upper row of terminals of the first mating power terminal portion of the electrical connector includes a first upper row body, a plurality of first upper row mating sides extending outward from one side of the first upper row body, and a plurality of first upper row fixing sides extending outward from the other side; and the first lower row of terminals of the first mating power terminal portion includes a first lower row body, a plurality of first lower row mating sides extending outward from one side of the first lower row body, and a plurality of first lower row fixing sides extending outward from the other side, and the two upper row terminals and the two lower row terminals are arranged in an upper and lower opposite manner.

6. The electrical connector as claimed in claim 1, wherein the second upper row of terminals of the second mating power terminal portion of the electrical connector includes a second upper row body, a plurality of second upper row mating sides extending outward from one side of the second upper row body, and a plurality of second upper row fixing sides extending outward from the other side; and the second lower row of terminals of the second mating power terminal portion includes a second lower row body, a plurality of second lower row mating sides extending outward from one side of the second lower row body, and a plurality of second lower row fixing sides extending outward from the other side, and the two upper row terminals and the two lower row terminals are arranged in an upper and lower opposite manner.
