As shown in FIG. 1 and FIG. 2, the base connector 1 includes a base housing 1 h, and the base housing 1 h has a base 12 which is fixed along the mounting surface 51, a pair of opposing side walls 12 a and 12 b erected on base 12, and a back wall 12 c which is orthogonal to the opposing first side wall 12 a and 12 b. The concave part 11 is surrounded by three sides of the base 12, the pair of opposing side walls 12 a and 12 b, and the back wall 12 c. As shown in FIG. 1 and FIG. 2, three planar blade contacts 3 are arranged at the back wall 12 c of the concave part 11, in parallel with the pair of opposing side walls 12 a and 12 b. As shown in FIG. 5, the blade contact 3 is held by the base 12 and second side wall 12 c in a state that it is inserted and engaged to fixing holes 121 and 122 formed at the back wall 12 c. As shown in FIG. 9, the blade contact 3 includes a rectangular board-shaped contact connection part 31 for connecting to the opposing contact 4 and a fixing part 32 which is provided at the base end of the contact connection part 31 and is inserted and engaged within the back wall 12 c. A bottom face extending in the longitudinal direction of the contact connection part 31 is in contact with the bottom surface of the concave part 11. The fixing part 32 extends the lead part 36, which is solder bonded to the printed circuit board 5, in the opposite direction of the contact connection part 31.
On the other hand, as shown in FIG. 3 and FIG. 4, in opposing housing 2 h, two convex pieces 24 a and 24 b are provided on a second outer wall formed in direction Y1, which is the opposite direction in which lead wire 4 w extends (refer to FIG. 1). In addition, second protrusions 25 a and 25 b are provided on one outer wall of these convex pieces 24 a and 24 b. When the opposing connector 2 is inserted towards the concave part 11, two convex pieces 24 a and 24 b are inserted into two grooves 14 a and 14 b, and second protrusion 25 a and 25 b go over first protrusions 15 a and 15 b, respectively. When the opposing connector 2 is completely inserted into the concave part 11, the second protrusions 25 a and 25 b are engaged with the first protrusions 15 a and 15 b, and the locked state of the socket connector 2 and the base connector 1 is maintained (refer to FIG. 11)
As shown in FIG. 1 and FIG. 2, a pair of projection parts 18 a and 18 b which face each other is provided on a pair of internal wall of 12 a and 12 b in the concave part 11. One projection part 18 a divides a fitting groove 13 a and a fitting concave part 16 a. In addition, one projection part 18 a is inserted between projection piece 23 a and fitting convex part 26 a. The other projection part 18 b divides the fitting groove 13 b and the fitting concave part 16 b. In addition, the other projection part 18 b is inserted between projection piece 23 b and fitting convex part 26 b. As shown in FIG. 1, FIG. 2, and FIG. 5, the pair of reinforcement tabs 17 a and 17 b, made of a metallic reinforcement component, is pressed to the pressing groove formed on the front lower part of the base housing 1 h. A part thereof is exposed to the bottom surface of the base housing 1 h, and it is solder bonded to the mounting surface 51 of the printed circuit board 5.
In FIG. 3 and FIG. 4, the opposing connector 2 has a rectangular opposing housing 2 h. A reception hole 21 is provided in opposing housing 2 h, in the direction in which the lead wire 4 w is ex holes 21 are aligned and provided in the opposing housing 2 h. Each reception hole 21 accommodates a socket contact 4 which is crimped to the end of the lead wire 4 w, respectively (refer to FIG. 9).
In addition, the pressing part 33 includes a pressing protrusion 33 a which is engaged within the back wall 12 c on the side facing the fixing arm 34. The pressing protrusion 33 a can be a fine protrusion which protrudes in a mountainous state and can be pressed such as to chumble the internal back wall which is formed of synthetic resin. In addition, the position of the blade contacts 3 are maintained firmly by mutually associated fixing arm 34 and pressing part 33 sandwiching the internal back wall 12 c. As shown in FIG. 9, a chamfer is formed on the upper edge 31 a and front edge 31 b of the contact connection part 31, facilitating the easy insertion of socket contact 4. In addition, a bottom surface extending in the longitudinal direction of the contact connection part 31 is in contact with the bottom surface of the concave part 11.
