摘要： A locking plate portion is disposed so as to be movable in a lateral direction. A connection terminal is inserted while a locking piece of a connection portion of the connection terminal passes through an insertion groove of the locking plate portion Subsequently, an operating member is pushed in an arrow direction with respect to the locking plate portion and the locking plate portion is laterally moved by a wedge mechanism. Then, the locking piece is transferred to a locking portion provided in the front end side portion of the insertion groove. As a result, the locking portion locks the rear portion of the locking piece and a rearward movement of the connection terminal is regulated.

摘要： In the conductor crimping portion (3), side portions (3a, 3b) are folded into a bottom layer plate (3c) and a top layer plate (3d), and edges of the side portions (3a, 3b) are abutted against each other to form a joint (3g).Additionally, three long groove-like punched long holes (3i to 3k), for example, are provided in an oblique direction with respect to a longitudinal direction of the crimp connection terminal in a bottom portion (3h) of the top layer plate (3d). A shallow round recessed portion (3l) is formed in the surface of the punched long hole (3i) by stamping. Edges (3m) of this recessed portion (3l) and new edges (3n′) formed by edges (3n) of the punched long hole (3i), obtained by the punching, being pushed inward by the stamping are formed in two steps.

摘要： Seal portions at two locations communicate with each other and are integrated with each other to realize a waterproof structure. A first seal portion is provided onto an outer surface at a tip of a central cylinder inside a housing main body to realize a waterproof structure where a gap between the outer surface and a housing of a mating electrical connector is sealed in a waterproof manner. The seal portion is also connected to an inner surface of the central cylinder through a communication hole provided in the central cylinder, and a second seal portion is provided on the inner surface, integrally with the seal portion, to realize a waterproof structure where a gap between the inner surface and a terminal holder is sealed in a waterproof manner.

摘要： In a conductor crimping portion 3, a pair of crimping pieces 3c and 3d having a two-layer structure of an upper layer plate 3a and a lower layer plate 3b connecting the upper layer plate 3a is raised in a U-shape from both sides of a bottom portion 3e. A void 3g is formed inside a folded-back portion of the upper layer plate 3a from the lower layer plate 3b. In the conductor crimping portion 3, the crimping pieces 3c and 3d have a two-layer structure, and a conductor portion is elastically fixed and connection becomes strong due to the presence of the void 3g.
