[0007]

[Action]

 In the wire connecting structure of the present invention, the connecting block is engaged with the connecting block of the wire located on the back side of the carrier plate, and the flange portion provided on the connecting block is inserted into the connecting hole of the carrier plate. By penetrating the plate from the back side to the front side and displacing the plate by a predetermined amount, the flange portion is prevented from coming off the connection hole and the carrier plate and the wire are connected. This makes it possible to easily connect the wires while keeping them on the back surface side of the carrier plate.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

This embodiment is an example of application as a wire connecting structure at a raising / lowering position of a windshield of an automobile, and as shown in FIG. 1, supports a windshield (not shown) and raises / lowers it. The carrier plate 1 is movably guided along the direction (arrows A and B in the figure), and is stretched so as to be located on the back side of the carrier plate 1 and reciprocates in the vertical direction of the windshield. It is configured to connect the wire 2 to be moved.

As shown in FIG. 2, the carrier plate 1 is provided with a flat circular thin portion 1A and a connecting hole 1B located in the thin portion 1A. The connecting hole 1B has a generally rectangular plane shape as a whole, a large-diameter portion 1B-1 is provided between the short side portions of the pair, and a plane substantially circular shape is formed by notching in the long side portion of the pair. A small diameter portion 1B-2 is formed between the arcuate portions. On the other hand, a substantially rectangular connecting block 3 is fixed to an intermediate portion of the wire 2.

Reference numeral 4 denotes a connecting body integrally formed of a synthetic resin material or the like, a lower portion (lower portion in FIG. 2) 4A of which has a cylindrical shape, and an intermediate portion 4B has a substantially square planar shape which is larger than the connecting hole 1B. The upper portion (upper portion in FIG. 2) 4C has a planar circular shape that is large enough to pass through the small diameter portion 1B-2 of the connecting hole 1B, and further, the connecting hole is formed on the left and right side portions of the upper portion 4C in FIG. A flange portion 4D having a quadrangular planar shape having a size passing through the large diameter portion 1B-1 of 1B is formed. A gap S (see FIG. 3) is formed between the flange portion 4D and the intermediate portion 4B. In addition, as shown in FIG. 4, the connecting body 4 is formed with a slit 4E that divides the connecting body 4 into two substantially from the upper portion 4C to the middle portion of the lower portion 4A. The width of the slit 4E is set so that the wire 2 can pass through it, and at the middle portion of the slit 4E in the left-right direction in FIG. 3, a flat surface having a size into which the connecting block 3 of the wire 2 can be fitted from above. A substantially square groove portion 4F is formed.

Next, a procedure for connecting the carrier plate 1 and the wire 2 will be described.

First, the wire 2 and the connecting block 3 are fitted into the slits 4E and the groove portions 4F of the connecting body 4, and then the connecting body 4 is connected to the connecting block 3 and the axis O as shown in FIG. Is rotated by 90 ° in one direction (in the case of this example, the direction of arrow C in FIG. 2). At that time, the wire 2 is slightly curved in the front and rear portions of the connection block 3. Then, the connection block 4 is inserted into the connection hole 1B from the back surface side of the carrier plate 1, the flange portion 4D is passed through the large diameter portion 1B-1, and the upper surface 4C is passed through the small diameter portion 1B-. It fits in 2. After that, the connecting block 3 together with the connecting body 4 is rotated by 90 ° in the opposite direction (in the case of this example, the direction of arrow D in FIG. 2) about the axis O, and the flange portion 4D is moved to the thin portion 1A of the carrier plate 1. Pressure contact with the upper surface of. As a result, as shown in FIG. 1, the connecting body 4 is prevented from coming off and the carrier plate 1 and the wire 2 are connected.

Then, in such a connected state, the wire 2 is reciprocated in the directions of arrows A and B, whereby the window glass (not shown) moves up and down together with the carrier plate 1.

At that time, the posture of the connecting body 4 is maintained by the tension of the wire 2 extending in the directions of the arrows A and B, and the connecting body 4 is prevented from falling off. Further, when the pulling direction of the wire 2 with respect to the carrier plate 1 is slightly changed, the connecting body 4 is rotationally displaced about the axis O 2 accordingly, the bending of the wire 2 is avoided, and its durability is improved. It will also be done.

In the above embodiment, the flange 4F is prevented from coming off by rotating the connecting body 4 by 90 °, but the rotation angle is the shape of the flange 4F and the connecting hole 1B. It can be arbitrarily set according to. Further, for example, by forming the connecting hole 1B into a shape in which the large-diameter hole portion and the small-diameter hole portion are continuous with each other, the connecting portion is linearly displaced to prevent the flange portion 4F from coming off. You can also

[0017]

[Effect of device]

 As described above, according to the wire connecting structure of the present invention, the connecting body is engaged with the connecting block located on the rear surface side of the carrier plate, and the flange portion provided on the connecting body is connected to the carrier plate. By piercing the carrier plate from the back side to the front side in the hole and then displacing it by a predetermined amount, the flange part is prevented from slipping into the connecting hole to connect the carrier plate and the wire. You can easily connect them while keeping them on the back side of the carrier plate.
