Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for an actuator used in an automobile or a motor used for driving a pump.

[0002]

2. Description of the Related Art One example of a conventional motor connector is shown in FIGS.

[0005] That is, in FIGS. 5, 6 and 7, a lead elastic body 23 inserted into a notch 22 provided at an end of a motor frame 21 is sandwiched between a peripheral edge of the notch 22 and a bracket 24. It is fixed.

As shown in FIG. 7, a portion of the motor frame 21 other than the cutout portion 22 is filled with a sealant 25 at a portion where the end surface of the motor frame 21 and the inner surface of the bracket 24 abut. As a result, the sealing property between the motor frame 21 and the bracket 24 was maintained.

In the notch 22, the sealing property is maintained by compression of the lead elastic body 23 inserted through the terminal 26, or a sealing agent 25 is applied to the outer periphery of the lead elastic body 23 as shown in FIG. The sealability was maintained.

[0006]

However, in the above-mentioned conventional structure, the sealing property of the portion of the lead elastic body 23 through which the terminal 26 is inserted is not sufficient, water may enter the motor, and the sealing agent may be used. 25 is a lead elastic body 2
The workability of coating the outer periphery of No. 3 was not good.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems in the structure of the prior art, and to provide a motor connector having better sealing properties by simple and reliable work.

[0008]

In order to solve the above-mentioned problems of the prior art, the present invention provides a base for inserting a terminal or a lead wire, an inner wall formed around the base,
An outer wall portion formed around the inner wall portion and connected to the inner wall portion by a connecting portion is integrally formed of insulating resin, the base portion is inserted into a cutout of a motor frame, and a front surface of the base portion, an inner wall portion, A motor connector that can be mounted in a liquid-tight manner on the motor frame and the bracket by filling a gap between the outer wall and the gap between the outer wall and the bracket and the gap between the outer wall and the motor frame with a sealant. It is.

Therefore, according to the motor connector of the present invention, the notch and the bracket of the motor frame can be mounted in a liquid-tight manner with the sealing agent, and the mounting operation is performed only by the filling operation of the sealing agent. It is.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a base according to a first embodiment of the present invention; FIG. 2 is a perspective view of the base; FIG. A motor connector in which the outer wall portion connected to the inner wall portion by a connecting portion is integrally formed of an insulating resin, wherein the base portion is inserted into a cutout portion of a motor frame,
A sealing agent is filled into the front surface of the base, between the inner wall and the outer wall, between the outer wall and the bracket, and between the outer wall and the motor frame, and is mounted in a liquid-tight manner on the motor frame and the bracket. It can be implemented.

The terminal or the lead wire serves to supply power to the motor, and is essential for the motor. The motor connector of the present invention prevents water from entering the motor, and furthermore, seals the sealant. It is very convenient because it can be mounted by a simple operation of filling.

According to the present invention, the brush can be easily mounted in the motor by forming the brush holder integrally with the base of the motor connector so as to be located in the motor. Things. Therefore, according to the present invention, not only a terminal or a lead wire for supplying power to the motor but also a brush for supplying power to the rotor can be integrally formed and mounted on the motor. Can be dramatically simplified as compared to The resin forming the motor connector may be not a special resin but an extremely general resin.

[0013]

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

(Embodiment 1) In FIGS. 1, 2 and 3,
The motor connector 1 supplies power to the motor, and is made of a heat-resistant synthetic resin such as polyethylene, polypropylene, polybutylene, nylon or polyethylene terephthalate.
It is made of a material such as a fluorine-based resin such as polypropylene terephthalate and polybutylene terephthalate, has a rectangular frame shape, and mainly includes an outer wall portion 2 and an inner wall portion 3 formed therein.

The outer wall portion 2 and the inner wall portion 3 are connected by a connecting portion 4. The bottom surface of the inner wall portion 3 has a base 6 through which a terminal 5 is conducted. The base 6 is a motor frame 7 made of an iron plate. And is held by being inserted into the notch 8 provided in the above. Reference numeral 9 denotes a bracket that supports a motor shaft bearing 10 and is press-fitted into the motor frame 7. Reference numeral 11 denotes a sealant having adhesiveness or adhesiveness such as a heat-resistant epoxy resin or polyamide resin, which is provided on the surface of the base 6 of the motor connector 1, between the inner wall 3 and the outer wall 2, and on the outer wall. A gap 12 between the part 2 and the bracket 9;
Further, the space 13 between the outer wall portion 2 and the motor frame 7 is filled. Therefore, the motor connector 1 is mounted in a liquid-tight manner with the sealant 11 on the adhesive portion including the notch 8 of the motor frame 7 and the bracket 9, and there is a fear that water may enter the motor through the mounting portion of the motor connector 1. Absent.

In addition, the work of mounting the motor connector 1 is simpler than filling the seal rubber 25 around the lead rubber 23 as described above. Note that the terminal 5 may be a lead wire.

(Embodiment 2) Next, Embodiment 2 of the present invention will be described in detail with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted.

The second embodiment is different from the first embodiment in that a brush holder 14 protruding into the motor frame 7 is formed integrally with the base 6 of the motor connector 1, and the brush holder 14 is used for the motor rotor. The point is that the brush 15 for feeding power is held.

Therefore, according to the second embodiment, the brush 15 can be held by using the motor connector 1 mounted on the motor frame 7 and the bracket 9 in a liquid-tight manner. The mounting to the motor connector 1 can be performed at the same time as the mounting of the motor connector 1, and the workability is good.

[0020]

As described above, according to the present invention, a motor connector in which an inner wall and an outer wall are integrally formed around a base through which a terminal or a lead wire for supplying power to a motor is inserted is provided with a notch of a motor frame and a bracket. Since the sealant is filled with a sealing agent in a liquid-tight manner, water does not enter the motor from the mounting portion of the motor connector, and the mounting of the motor connector is simple and has good workability.
