BEST MODE FOR CARRYING OUT THE INVENTION As an embodiment of the present invention, a movable connector with a fitting guide attached to an instrument panel of an automobile will be described. FIG. 1 is a perspective view showing a male connector 11 fitted into a female connector 21 mounted in a mounting hole 32 of an instrument panel bracket of an automobile. The male connector 11 is provided with a plate-shaped guide rod 13 protruding in the central portion of the connector housing 12 in the fitting direction with the mating female connector 21 and having an axis aa '. There are tapes on the four sides of the tip of the guide bar 13.
A pad 14 is provided and the tip is tapered.
A plurality of electric terminals 15 are arranged on a pair of upper and lower surfaces of the guide rod 13. The guide rod 1 of the male connector 21 is provided at the center of the connector housing 22 of the female connector 21.
An insertion hole 23 into which 3 is inserted is provided. Insertion hole 2
Tapers 26 are provided on the four sides of the hole edge portion on the guide rod insertion side of No. 3 to widen the entrance portion. The flexible arm 24 extends in the direction of the mounting hole 32 of the instrument panel bracket with an appropriate bending distance e between the flexible arm 24 and the outer wall of the connector housing 22 through the rising base portion 27, and is provided at the tip of the arm. It is locked in the mounting hole 32 of the instrument panel bracket by the claw 28. Further, a retainer 25 is provided in a square of the connector housing 22 in the direction in which the flexible arm 24 extends. The quadrilateral formed by the four retaining members 25 is made larger than the mounting hole 32 of the instrument panel bracket. Further, the retainer 25 has a flexible connector to which the female connector 21 is attached.
The size is such that the female connector 21 does not come off from the mounting hole 32 of the instrument panel bracket even when the maximum bending distance e of the frame 24 is moved. The female connector 21 is attached to a mounting hole 32 of the instrument panel bracket by a flexible arm 24 and a retaining member 25.

FIG. 2 shows the female connector 21 mounted in the mounting hole 32 of the instrument panel bracket 31 and the mounting hole 34 of the instrument panel design surface 33 in the mounting hole 34 of the instrument panel design surface 33 on the driver's side B of the instrument panel design surface 33.
It is sectional drawing which shows the state in the middle of fitting the male connector 11 inserted from. First, a method of attaching the female connector 21 to the attachment hole 32 of the instrument panel bracket 31 will be described. Female connector 21 mounting hole 3
When the instrument panel bracket 31 is inserted from the engine room side A with respect to 2, the flexible arm 24 passes through the rising base portion 27, and the maximum rising portion 29 catches the mounting hole 32. Here, when the female connector 21 is pushed in a little more, the flexible arm 24 bends, the maximum rising base portion 29 passes through the mounting hole, and the retainer 25 comes into contact with the instrument panel bracket 31. The claw 28 at the tip of the hole 24 engages with the hole edge of the mounting hole 32, and the female connector 21 is mounted in the mounting hole 32 of the instrument panel bracket 31. FIG.
As shown in, the spring portions 42 of the electric terminals 41 are arranged in pairs in the insertion hole 23 of the female connector 21 so as to face each other. The distance f between the pair of spring portions 42 is set to be slightly smaller than the thickness g of the terminal forming portion 15 of the guide rod 13 of the male connector 11. Further, terminals other than the above-mentioned electric terminals can be arranged on the surface of the male connector 11 on which the guide rod 13 is attached, other than the portion on which the guide rod 13 is attached. Correspondingly, it can be arranged on the surface of the female connector 21 on the insertion side of the insertion hole 23 other than the portion of the insertion hole 23.

FIG. 3 shows that the male connector 11 has been fitted to the female connector 21 mounted in the mounting hole 32 of the instrument panel bracket 31, and the male connector 11 has been completed.
FIG. 6 is a cross-sectional view showing a state in which the instrument panel design surface 33 is also attached to a mounting hole 34. Here, a method of fitting the male connector 11 to the female connector 21 will be described. First, as shown in FIG. 2, the insertion hole 23 of the female connector 21 attached to the attachment hole 32 of the instrument panel bracket 31 is inserted from the driver seat side B of the attachment hole 34 of the instrument panel design surface 33. Even if the guide rod 13 of the inserted male connector 11 is slightly displaced, the taper 26 of the insertion hole 23 of the female connector 21 picks up the taper 14 of the guide rod 13 of the male connector 11, and the taper of the insertion hole 23 is removed. The position of the guide bar 13 is gradually corrected while being guided by the par 26. At this time, the female connector 21
Due to the flexibility of the flexible arm 24, the main body of the female connector 21 moves upward, and the taper 26 of the insertion hole 23 is guided by the guide rod 13.
To assist the function of guiding. Further, when the fitting is further advanced, the tip of the guide rod 13 is inserted so as to widen the gap f of the spring portion 42 of the electric terminal 41 in the insertion hole 23, and as shown in FIG. The spring portion 42 of the terminal 41 sandwiches the electric terminal 15 of the guide rod 13, and both electric terminals are connected. As shown in FIG. 3, the fitting of both connectors is completed in a state where the male connector 11 is mounted in the mounting hole 34 of the design surface 33 of the instrument panel via the flexible arm 16. At this time, both terminals are completely in contact with each other due to the effect of the spring of the spring portion 42 of the electric terminal 41 in the insertion hole 23. As shown in FIG. 3, the mounting hole 32 of the instrument panel bracket 31 is attached to the mounting hole 34 of the instrument panel design surface 33.
Has been constructed slightly off, but
Guide function for both connectors and insertion hole 2 for male connector 11
By the effect of the spring of the spring portion 42 of the electric terminal 41 and the position correcting function of the flexible arm 24 of the female connector 21 in FIG. 3, the fitting of both connectors is made smooth at the regular position. .

The present invention can be used not only as an instrument panel of an automobile but also as an electric connector for various electric wirings, and the shape and structure of each member is also limited to the illustrated embodiment. Not something.

[0010]

By using the present invention, (a) the guide function of the guide rod of the male connector and the insertion hole of the female connector, and the flexibility of the flexible arm allows the female connector to move vertically and horizontally. As a result, the positions of both connectors are regulated to an appropriate position where they can easily be fitted together, so that both connectors can be reliably and smoothly fitted at the proper positions. (B) Due to the spring action of the electric terminal in the insertion hole, both terminals are reliably connected even if there is a dimensional error in manufacturing such as the guide rod or the insertion hole, and contact failure does not occur. (C) The guide rod and the insertion hole do not only have a guide function,
Since both have electric terminals, space efficiency is good. And so on.
