Abstract

PROBLEM TO BE SOLVED: To use a coupler housing chamber as a reinforcing beam between flexible plate faces so as to bring the coupler housing chamber side wall into contact with a coupler for preventing the coupler from turning by expanding the recessed cavity type coupler housing chamber formed in a first plate face part to a second plate face part in formation. SOLUTION: A coupler 14 having a lead wire 14b is housed in a coupler housing chamber 13 formed in a bracket. The coupler housing chamber 13 is formed into a recessed cavity shape in a first plate face part while expanded toward a second plate face part 11b. As the coupler 14 is installed with fitted inside the coupler housing chamber 13, the coupler 14 is prevented from protruding and its mounting structure can be compact in size. Because the coupler housing chamber 13 is arranged in a dead space, a space is formed between an interior plate and it, and interference can be prevented. The coupler housing chamber 13 functions as a reinforcing rib connecting flexible inside face parts of the first and second plate face parts 11a, 11b together. As two sides are opened in the recessed cavity type coupler housing chamber 13, assembly of the coupler 14 is not disturbed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to a technical field for mounting a coupler to which a lead wire is connected.

[0002]

2. Description of the Related Art Generally, when this type of coupler is mounted on a plate-shaped bracket portion of a base material, it is sometimes required to mount the coupler in a non-rotating manner on the bracket.
In such a case, conventionally, as shown in FIG. 6, a detent piece 30a is formed so as to protrude from the plate-shaped bracket portion 30, and this detent piece 30a is raised on the coupler 31 side to interfere with the side wall of the coupler 31. I was trying to stop it.

[0003]

However, in this case, since it is necessary to form the detent piece 30a, the position of the coupler mounting portion is not allowed to be limited to the edge of the bracket portion 30, and the bracket portion 30a is not allowed. Is bent to the opposite side to the coupler mounting surface, the coupler 3
1 is mounted in a state of protruding from the bracket portion, so that it is inevitably increased in size and easily interferes with other members. In addition, when the bracket portion 30 is bent, it is necessary to appropriately form a reinforcing bead (rib) 32 to protect the bent portion, and there is a problem that the bracket structure becomes complicated. These have problems to be solved by the present invention.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems in view of the above-mentioned circumstances, and when attaching a coupler to a bracket portion, the bracket portion is It has a first plate surface portion and a second plate surface portion that are continuous in a bent shape, and the coupler mounting portion is
A concave coupler housing chamber formed in the first plate surface portion so as to swell toward the second plate surface portion is formed so as to reach the second plate surface portion. In this case, the coupler accommodating chamber is a reinforcing bead at the bent portion of the first and second plate surface portions. According to the present invention, in this manner, the coupler housing chamber can be used as a reinforcing bead between the bent plate surfaces, and the side wall of the coupler housing chamber interferes with the coupler so that the coupler is stopped from rotating. This eliminates the need to provide an upright portion on the coupler side from the bracket, thereby preventing the coupler from protruding from the bracket surface.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes an electric motor for a vehicle. The electric motor 1 includes a motor shaft 3 rotatably supported by a bottomed cylindrical yoke 2, and a motor shaft 3.
Armature core 4 attached to armature core 4, coil 5 wound around armature core 4, permanent magnet 6 attached to the inner peripheral surface of yoke 2, commutator 7 attached to motor shaft 3, commutator 7 , And is configured using various members such as a brush 8 which is slidably contacted with the base member.

On the other hand, reference numeral 9 denotes a case frame integrally attached to the opening-side edge of the yoke 2. The tip of the motor shaft 3 projects from the yoke 2 and is housed in the case frame 9. However, at the tip of the motor shaft 3,
A series of members for deceleration are provided and output to the output shaft 10 in a decelerated state, which also has a conventional configuration. The output shaft 10 passes through a through hole 17 a provided in a window glass 17 provided continuously with a vehicle body outer panel (outer panel) 16, and the grommet 1.
8. The wiper arm 15 is supported in a watertight manner by using a collar 19, and a tip end of the output shaft 10 protruding outside the vehicle.
Is attached using an attachment member such as a nut (not shown).

The electric motor 1 and the case frame 9 are provided in a plate-like bracket 11 in which the present invention is implemented.
Mounted on In other words, the bracket 11 is bent at both ends of the first plate surface portion 11a to which the electric motor 1 and the case frame 9 are mounted so as to be continuous in an L shape toward the electric motor mounting surface side in a side view.
It has third plate portions 11b and 11c, and the second plate portion 11b and the first plate portion 11a on the case frame 9 side.
In between, the coupler mounting portion 12 is formed.
In other words, the coupler mounting portion 12 is formed by forming the coupler accommodating chamber 13 formed in a concave shape in the first plate surface portion 11a so as to swell toward the second plate surface portion so as to reach the second plate surface portion 11b. Thereby, the coupler housing chamber 13 has a side opposite to the side where the second plate surface 11b of the first plate surface 11a is bent and a side opposite to the side where the first plate surface 11a of the second plate surface 11b is bent. Each of the side walls 13a constituting the coupler accommodating chamber 13 functions as a bead (reinforcing rib) for reinforcing a bent portion between the first and second plate surface portions 11a and 11b. It has become. A mounting hole 13b is formed in the bottom wall portion of the coupler accommodating chamber 13 so as to penetrate the engaging projection 14a provided on the coupler 14 in a forcibly fitting manner and to attach the coupler 14 thereto. The coupler 14 is mounted so as to fit inside the coupler housing chamber 13, and the mounted coupler 14 is set to be prevented from rotating by hitting both side walls 13 a of the coupler housing chamber 13. In addition, 14b is a lead wire connected to the coupler 14. The three mounting portions 11d provided on the bracket 11 are bolted to the inner panel 16a provided on the rear surface side of the outer panel 16 of the vehicle via a mount rubber or the like. Also, an interior plate 20 that forms the interior surface of the vehicle is covered on the inside of the vehicle at this mounting portion so as to cover the motor 1.
a.

In the embodiment of the present invention configured as described above, the coupler 14 having the lead wire 14a connected thereto.
Is mounted in a state of being internally fitted in a coupler accommodating chamber 13 formed in the bracket 11, and the coupler accommodating chamber 13 is swelled toward the second plate surface side.
1a is formed so as to reach the second plate surface portion 11b as it is. As a result, the coupler 14 is fitted inside the bent portion of the bracket 11 instead of outside the bent portion. As a result, the coupler 14 does not protrude to the outside, and as a result, the coupler 14 can be prevented from protruding outside the contour of the bracket as in the related art, thereby achieving compactness. By locating in the conventional dead space, a clearance is created between the coupler 14 attached to this portion and the interior plate 20, and the problem of easy interference can be solved. In addition, since the coupler accommodating chamber 13 functions as a reinforcing rib connecting the bent inner side surfaces of the first and second plate surfaces 11a and 11b, the two plate surfaces 11a and 11b
Can be effectively used as it is without separately forming a reinforcing rib, and the bracket 1 can be used.
1 can be simplified. Since the two sides are open, the insertion of the coupler (not shown) on the opposite side will not be hindered even though the coupler housing chamber 13 has the concave shape as described above.
