BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay connector for connecting electrical equipment.

[0002]

2. Description of the Related Art Conventionally, for example, the relay connector shown in FIG. 6 is known. As shown in FIG. 6, the relay connector has terminals c projecting from housings a and b in which connection plugs (not shown) are formed so as to be freely inserted. The terminal c is inserted into a mounting hole (not shown) formed in the printed circuit board d, and the terminal c and the printed wiring e are soldered to form a pair of the two housings a and b. The terminals c, c are made conductive, and the housings a, b are connected to both side surfaces of the printed circuit board d.

[0003]

However, in the relay connector described above, it is necessary to secure a working space for soldering the terminals c and the printed wirings e. a, a and b,
b, b must be connected with a predetermined interval f between them. Therefore, high-density connection to the substrate d becomes impossible, and the printed circuit board is required in addition to increasing the size.

The present invention has been made in view of the above-mentioned problems of the above-mentioned conventional relay connector, and it is easy to assemble a predetermined arrangement simply by pressing a pair of housings symmetrically into a mounting bracket. An object of the present invention is to provide a relay connector that can be used, does not require a printed board, can use a mounting plate such as an iron plate, can be easily and densely fixed to the mounting plate, and has a low cost.

[0005]

In order to achieve the above object, a relay connector according to the present invention includes a square-tube-shaped mounting bracket, a pair of housings and terminals, and the mounting bracket includes left and right mounting brackets. A horizontal receiving piece for holding the hole edge of the mounting hole formed in the mounting plate and a locking piece having elasticity so as to be elastically deformable inward are provided at a predetermined interval substantially in the middle of the side wall of the mounting plate in the vertical direction. At the top and bottom of the left and right side walls, the locking pieces for each housing are inclined downward from the upper part to the lower inner side, and the locking pieces on the lower side are lowered from the lower part to the upper side. The pair of housings are formed so that they can be fitted to the upper and lower portions in the mounting bracket and can be joined together at a substantially central position in the mounting bracket. Each of the mounting brackets on the left and right side wall surfaces At the position corresponding to the stop piece, when the two housings are butted together in the mounting bracket, each of the locking pieces is provided with a locking concave groove that slides and locks, and a terminal step portion thereof. A terminal insertion hole is provided through the bottom of the insertion recess at a predetermined interval and penetrates the terminal. The pair of terminals are connected at both upper and lower ends, and are bent at the center to form a substantially half-crank side surface. The pair of housings are pushed into the mounting bracket from both ends from both ends to abut each other at a center position, and the pair of terminals are inserted and held in terminal insertion holes of each housing. And

[0006]

When a pair of two housings are pushed into the openings at both ends of the mounting bracket, a locking piece protruding from the inner surface of the side wall of the mounting bracket outwardly against the spring property due to the outer surface of the housing. By being pressed and deformed, the two housings are pushed into the mounting bracket, and the protruding ends of a plurality of terminals fixed and protruded in advance in one housing are inserted into the terminal insertion holes formed in the other housing. When the two housings abut against each other at the intermediate portion of the mounting bracket, the locking piece returns to the locking groove formed in the outer surface of the two housings by a spring property, and the leading end and the groove are returned. The relay connector is formed by engaging the two end surfaces with each other and combining the two housings and the mounting bracket.

[0007] In the relay connector thus formed, both ends of each terminal protrude into a concave hole for insertion of a connection plug, which is provided in both housings.

When the relay connector is fixed to the mounting plate, the mounting bracket is pushed into the mounting hole formed in the mounting plate from one end thereof, and a projecting locking piece is formed on the side wall surface of the mounting bracket. By abutting against the opening edge of the mounting hole and further pushing in, the locking piece is pressed and deformed inwardly against the spring property, so that the mounting bracket is pushed down to an intermediate portion thereof,
The receiving piece abuts one side of the mounting plate. At this time, the locking piece comes off from the opening edge of the mounting hole and at the same time returns to the outside by the spring property, and its tip is locked to the other side surface of the mounting plate. As a result, the mounting plate is sandwiched between the receiving piece and the locking piece, and the relay connector is fixedly held by the mounting plate.
