Abstract
The invention discloses a shielding type connector which comprises a base. The base comprises an insulation body. A plurality of through grooves penetrate through one side of the insulation body. Due to the fact that the through grooves are further sunk, a plurality of locating grooves are formed and penetrate through the other side of the insulation body. Shielding bodies are arranged in the through grooves. The shielding bodies are not arranged in the locating grooves. At least one guide connection body is connected with each shielding body. The guide connection body is in electric connection with at least one export portion to a mother board. Each electric conduction terminal is provided with a contact portion. A main body portion extends from each contact portion. Each main body portion comprises a locating section, a breakover section, a notch and a connection portion, wherein the locating section extends from each contact portion and is in interference fit with each locating groove, and the breakover section extends from each locating section and enters into each through groove. The breakover sections are not in interference fit with the through grooves. Each notch is arranged in the junction of each locating section and each breakover section. The shielding type connector is capable of not only guaranteeing that the electric conduction terminals are stably fixed in the insulation body, but also avoiding that the electric conduction terminals are in short connection with the shielding bodies.
