Description

  The present invention relates to a relay connector unit used for electrical wiring of a vehicle, for example.

  A relay connector is often used for electrical wiring of a vehicle such as an automobile. FIG. 8 is a diagram showing a general relay connector unit (relay connector) 101. This relay connector unit 101 is connected to, for example, an A / T case of a vehicle. The oil-inside female connector 120 to which the electric wire 130 (harness) with the crimp terminal as shown in FIG. 8A is attached is attached to the relay connector main body 110. Further, as shown in FIG. 8B, the bracket 140 is attached to the relay connector main body 110. In this type of relay connector unit 101, as shown in FIG. 8 (c), due to the tension (indicated by the arrow in the figure) that occurs when the relay connector unit 101 is routed, and in particular, the wiring operation of the electric wire 130 with the crimp terminal is performed. When the relay connector main body 110 is pulled, the bracket 140 may be inclined. This must be avoided because it can cause damage and failure.

  Various countermeasure technologies have been proposed for such problems. For example, the relay connector main body is swingable in the front-rear and left-right directions and elastically supported by the first bracket receiver and the second bracket receiver provided at two positions displaced by 90 ° with respect to the bracket, There is a technique of mounting in a vertically slidable state (see, for example, Patent Document 1).

Therefore, the cap 50 can move by a predetermined amount (by gaps c and d) on both sides in the X direction from the design center point. That is, the presence of the gaps c and d enables the relay connector main body 10 to be aligned in the X direction.

  Further, as shown in FIG. 5B, in the state where the relay connector main body 10 is attached to the bracket 40, the second protrusion one end face 16c and the second attachment hole side one end face 47c along the Y direction. A gap g is provided between the second projection part other end face 16d and the second attachment hole side other end face 47d. Therefore, the second protrusion 16 can move by a predetermined amount (by gaps g and h) from the design center point to both sides in the Y direction. That is, the presence of these gaps g and h enables the Y-direction alignment of the relay connector main body 10.

  Further, as shown in FIG. 5A, in a state where the relay connector main body 10 is attached to the bracket 40, a gap is formed between the cap side upper surface 50a and the first attachment hole side upper surface 44a along the Z direction. a is provided, and a gap b is provided between the cap-side lower surface 50b and the first attachment hole-side lower surface 44b. Further, as shown in FIG. 5B, in the state where the relay connector main body 10 is attached to the bracket 40, the second protrusion 16 and the second attachment hole 47 are formed along the Z direction. A gap e is provided between the part upper surface 16a and the second attachment hole side upper surface 47a, and a gap f is provided between the second protrusion lower surface 16b and the second attachment hole side lower surface 47b. Therefore, the cap 50 can move by a predetermined amount (by the gaps a and b) from the design center point to both sides in the Z direction. Further, the second protrusion 16 is movable by a predetermined amount (by gaps e and f) to both sides in the Z direction from the design center point. That is, the presence of the gaps a and b and the gaps e and f enables the relay connector main body 10 to be aligned in the Y direction. The gap a and the gap e may be the same or may be set to different values. The same applies to the gap b and the gap f.

<Subduction suppression function>
As described above, in the state where the relay connector main body 10 is attached to the bracket 40, the gap b is provided between the cap side lower surface 50b and the first attachment hole side lower surface 44b along the Z direction. Further, as shown in FIG. 5 (b), in a state where the relay connector main body 10 is attached to the bracket 40, the second protrusion bottom surface 16b and the second mounting hole side lower surface 47b are arranged along the Z direction. Is provided with a gap f. Therefore, the sinking of the relay connector body 10 can be suppressed by the contact of these facing surfaces.
