The housing 1 of the electrical connector is provided with bracket insertion and fixing parts 2, 2 on both end faces thereof, respectively, for attaching a bracket 3 which is fixed in advance to an automobile or the like. The bracket 3 is provided with upright parts 3a, 3a at both ends thereof, which stand up along the mounting direction of the bracket 3 (direction of arrow C in the figure), and the upright parts 3a, 3a are connected to the bracket insertion and fixing parts 2, 2. are inserted respectively. Note that since the bracket insertion and fixing parts 2, 2 are symmetrical, one of them will be explained below. As shown in FIGS. 2 and 3, the internal structure of the bracket insertion and fixing portion 2 includes guide portions 4A, 4A that are provided integrally with the side end surface 1a of the housing 1 and extend vertically from the side end surface 1a. An outer wall plate 7 supported so as to be parallel to the side end surface 1a with the support parts 6 and 6' as legs forms a gap into which the upright part 3a can be inserted. The inner wall surface 7a of the outer wall plate 7 and the side end surface 1a of the housing opposite to the inner wall surface 7a are provided with flexible bridges 8, 8' which are convex toward the inside, respectively. The pair of guide parts 4A, 4A' are provided with an interval equal to or slightly narrower than the width of the upright part 3a in the front-rear direction (direction of arrow B in FIG. 2).
The guide parts 4A, 4A' are followed by the bridge 8,
8', second guide parts 4B and 4 are provided with the same spacing as the guide parts 4A and 4A'.
It is inserted into the bracket insertion and fixing part 2 while being guided by B' and pressing the bridges 8, 8' to bend them. A protruding locking portion 5 is provided on the surface of this bridge 8, and a locking portion 3b that engages with this locking portion 5 is provided on the standing portion 3a, so that the bridge The locking portion 5 and the locking portion 3b of the standing portion engage with each other to prevent the standing portion 3a from coming off in the direction opposite to the insertion direction. Furthermore, the bracket 3 is provided with an upright piece 3c that stands up in the same direction as the upright part 3a through a groove part 3d, and the width of the groove part 3d gradually decreases downward, and the locking part 5 and Both lower ends of the guide portion 4A come into contact with the groove portion 3d at the position where the upright portion 3a is inserted to the position where the locking portion 3b is engaged. Further, a stepped portion 3e is formed on the opposite side of the raised portion 3a from the groove portion 3d, and is adapted to come into contact with the guide portion 4A' when the raised portion 3a is inserted to the above-mentioned position.

Therefore, the upright portion 3a is not inserted beyond the position where the locking portion 5 and the locking portion 3b are engaged, and the position is fixed without wobbling in the vertical direction. In addition, since it is supported by the two pairs of guide parts 4A, 4A' and 4B, 4B' in the front-rear direction (direction of arrow B), there is no risk of positional deviation, and the upright part 3a can be inserted to a predetermined position. After that, the housing 1 can be securely fixed to the bracket 3.
