In the present invention, the lower end of the side surface of the insulative housing 10 (the rear side surface and the right side surface in the present example) is outwardly formed with a positioning block 13 , and the corresponding welding groove 153 of the positioning block 13 is vertically penetrated and provided with an outwardly extending positioning groove. 131, the welding groove 4 M429230 153 is in communication with the positioning groove m. A convex block 14 is protruded from the front surface of the insulative housing 10, and an annular retaining portion 123 having a central axis coincident with a central axis of the abutting portion 12 is protruded from the outer surface of the abutting portion 12, and the front surface of the annular latching portion 123 is An arcuate or inclined guide surface 1231 is formed at the joint of the outer surface of the abutting portion 12. Please refer to the second ®, the plurality of terminals 2D includes a plurality of electrical connection terminals (FIG. 2 unlabeled (2) P-lion terminals 2 丨. Specifically, the electrical connection includes two signal terminals 22, a ground terminal 23 and - a first switch terminal 24 and a second switch terminal 25. The auxiliary terminal 21 includes a retaining portion 2H and an elastic portion 212. The retaining portion 211 is retained in the auxiliary terminal slot 16 of the insulative housing 1 , and the elastic portion 212 protrudes into the mating hole 120 The signal terminal 22 includes a vertical plate-shaped holding portion 221, a contact portion 222 bent from the upper side edge of the holding portion 221 ▲ and a curved portion from the lower side edge of the holding portion 22 ι The crimping portion 223 is folded out. The grounding terminal 23 includes a vertical plate-shaped holding portion 231, a crimping portion 233 extending outwardly from the lower side edge of the holding member 231, and a front side edge from the holding portion an After extending forward, then extending inwardly and then extending inwardly and then extending inwardly, the bent portion 234 and the contact from the lower end of the front end of the folded portion 234 and the edge are bent inwardly. P 232 'contact portion 232 end inner side & a convex bulge 232 contact portion 232 extends into The convex hull 2321 extends through the opening 122 into the butting hole 12A. The first switch terminal 24 includes a vertical plate-shaped holding portion 241, and a yoke extending from the lower side of the holding portion 241 and the outer edge of the ridge. The formed crimping portion 243 and the contact portion formed by bending forward from the left edge of the holding portion 241.
