The electrical connection between the motor and the switch mechanism does not employ a method of directly inserting and connecting a female socket to each connection terminal. For example, in the case of a motor, this means that a female socket is not inserted and connected to a connection terminal directly protruding from the motor. This is because the mounting position of the motor itself is not constant, and the positions of the connection terminals protruding from the motor are also uneven due to individual differences. . Conventionally, as shown in FIG. 1, a male socket c is formed by insert-molding a middle position in the length direction of a metal terminal a formed to a predetermined length on a synthetic resin base b. 1, the tip is connected to the connection terminal f of the motor e, the male socket c is inserted into the pin g, fixed so as not to come off, and the female socket d is fitted. However, in FIG. 1, the male socket c is formed by insert-molding the middle of the terminal a on the synthetic resin base b. However, this method is disadvantageous in that the cost is high and the male socket c is connected to the pin g. Is inserted and fixed, there is a disadvantage that this operation is troublesome, and there is a problem that the connection between the terminal a and the connection terminal f is a place that cannot be seen, so that the connection is made relying on the feeling, so that it is uncertain. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
1 is a front case (or one case), 2 is a rear case (or the other case), and both the front case 1 and the rear case 2 are made of synthetic resin. The front case 1 and the rear case 2 of the embodiment are both formed such that the lower side is bent rearward (FIG. 2) because the shape is adapted to the shape of the vehicle door.

An output shaft 3 is fixed to the front case 1, and a sector gear 4 fixed to the output shaft 3 is attached to the front case 1. Reference numerals 5 and 6 denote reduction gears, which cover the mounting metal plate 7 on the rear side and are fixed with screws 8, and the motor 9 is fixed to the mounting metal plate 7. The motor 9 fixes the front side of the motor 9 to the mounting metal plate 7 so that the axis thereof projects rearward with the shaft center in the front-rear direction, and meshes the reduction gear 6 with the drive shaft projecting forward of the motor 9.

Reference numeral 10 denotes a pair of connection terminals protruding to the rear side of the motor 9. When the motor 9 is energized, the sector gear 4 rotates about the output shaft 3, and turns clockwise to lock, and turns counterclockwise to unlock (the opposite is also possible). A switch 11 for detecting lock / unlock is used for mounting. The contact piece provided on the back side of the metal plate 7 via an insulating material or on the front case 1 and provided on the sector gear 4 comes into contact with the switch 11 to indicate lock / unlock. 1
2 is a lead cord group having one end connected to the switch 11, 13
Is a terminal, and the terminal 13 is exposed to the outside at an intermediate position between the front case 1 and the mounting metal plate 7. The reason that the terminal 13 is exposed to the outside is that the connection can be monitored with the naked eye. Reference numeral 14 denotes a sub cover formed of a synthetic resin, which has a hook shape when viewed from above, includes a head 15 and side portions 16, and has a rotating shaft on the rear side of the motor 9 inside the head 15. A recess 18 is formed in which an end of the motor 17 is fitted.
An insertion portion 21 composed of a circular through hole 19 slightly larger in diameter than the terminal 10 and a square through hole sub-through hole 20 communicating with the through hole 19.
To form

A terminal 22 connected to the terminal 10 for forming the male socket has a curled cap 23 inserted from the outside into the through hole 19 to cover the connection terminal 10 completely, and a terminal 22 from the outside into the sub through hole 20. The terminal part 24 is formed integrally with a side face of the cap 23. Terminal 2
2 can be inserted from the inside of the head 15.

A connection terminal 25 inserted and connected to the terminal 13 is fixed to the outer surface of the side portion 16. The terminal portion 24 and the connection terminal (terminal portion) 25 protrude rearward from insertion holes 26 and 27 formed in the rear case 2 of the same length at an interval determined to be a male socket.

Rear case 2 in which insertion holes 26 and 27 are formed
The wall surface 28 also has the function of pressing the terminal portions 24 and 25 and the head portion 15 on the inner surface to prevent the terminal portion from moving. The terminal portions 24 and 25 protrude outward longer than the insertion holes 26 and 27, and form a coupler 29 therearound. The coupler 29 has a cylindrical shape with the wall surface 28 as a bottom, and has several ribs 30 formed on the outer surface. The rear case 2 is fixed to the front case 1 by screws.
At 8, the terminal portions 24 and 25 are pressed to form a precision male socket similar to the insert molded terminal sub-b of the known example.

[0011]

After the output shaft 3, the sector gear 4, the reduction gears 5 and 6, the switch mechanism 11 and the like are assembled on the front case 1, the mounting metal plate 7 is put on and fixed with screws 8. The front side of the motor 9 is mounted on the mounting metal plate 7 so that the axial center is in the front-rear direction, and the connection terminal 10 of the motor 9 is protruded rearward (FIGS. 3 and 4). The end of the drawer cord 12 is fixed to the switch 11 attached to the front case 1, and the terminal 13 of the drawer cord 12 is fixedly exposed to the outside of the mounting metal plate 7 on the side of the front case 1. I do.

On the outer surface of the side portion 16 of the separately formed synthetic resin sub-cover 14, several small projections 3 are formed.
Since the holes 3 are formed, the through holes 34 of the connection terminal 25 are aligned with and engaged with the small projections 33, and are fused and fixed.

The head 15 of the sub-cover 14 is formed with an insertion portion 21 and a recess 18 formed of a through hole 19 and a sub-through hole 20. The recess 18 is fitted to the rotating shaft 17 of the motor 9, and the connection terminal 2
5 is fitted to the terminal 13 of the withdrawal cord group 12. The connection between the connection terminal 25 and the terminal 13 can be confirmed directly with the naked eye. After the sub cover 14 is mounted, the cap 23 of the terminal 22 is fitted into the through hole 19 from the outside of the head 15, and the terminal portion 24 of the terminal 22 is fitted into the sub through hole 20. This condition can also be confirmed directly with the naked eye.

After confirming the fitting of the connection terminal 25 and the terminal 13 and the fitting of the cap 23 and the connection terminal 10, the rear case 2
When the terminal portion 24 is projected from the insertion hole 26 to the rear of the connection terminal 25 from the insertion hole 27, the insertion holes 26 and 27 are formed at an accurate insertion interval. Connection terminal 25
Protrude in parallel, and the coupler 29 is formed around it, so that it becomes a male socket. Therefore, if the female socket 32 is inserted into the coupler 29, it can be accurately connected.

[0015]

As described above, the electrical connection between the motor and the switch mechanism is not such that the female socket is directly connected to each connection terminal. For example, in the case of a motor, if a female socket is inserted and connected directly to the connection terminal protruding from the motor, the mounting position of the motor itself is not constant, and the positions of the connection terminals protruding from the motor are relatively uneven. This is because, for some reasons, poor contact occurs. In a conventional example, as shown in FIG. 1, a lengthwise intermediate portion of a metal terminal a is inserted into a synthetic resin base b to form a precisely formed male socket c, which is fitted as shown in the figure. The female socket d is fitted so that it does not come off with the pin g, but in the case of FIG. 1, the middle of the terminal a is insert-molded into the synthetic resin base b to form the male socket c. The disadvantage is that the cost is high because of this, the disadvantage is that the male socket c must be fixed with the pin g because the terminal a is inserted only into the connection terminal f, so that the terminal a may come off. Since the connection with the terminal f is a place that cannot be seen, there is a problem that the connection is made by feeling.

In the present invention, however, one case 1 made of synthetic resin to which the motor 9 and the switch mechanism 11 and the like are fixed, and the other case 2 made of synthetic resin surrounding the motor 9 and the switch mechanism 11 and the like are provided. The terminal portions 24 and 25 connected to the motor 9 and the switch mechanism 11 and the like are provided with the insertion holes 2 formed at predetermined intervals formed in the other case 2 when the other case 2 is covered.
6 and 27 are provided so as to protrude outward in the same length in a fixed manner, and a coupler 29 for inserting the female socket 32 is provided on the outer surface around the insertion holes 26 and 27.
Since the connection device for a vehicle actuator is formed integrally and swelled on the other case, when the other synthetic resin case 2 is put on the connection device, it is provided at a predetermined interval formed on the case 2. Terminal part 2 from insertion holes 26 and 27
4 and 25 are fixedly protruded outward in the same length, and the coupler 29 for inserting the female socket 32 is integrally swelled with the case 2 so that the other case 2 Since the male socket is also used, there is no need for insert molding as in the known example, so that it can be formed at low cost.
Is fixed only with screws, so that there is an effect that the trouble of fixing a separately formed male socket with pins as in a known example can be omitted. The present invention also relates to a front case 1 made of synthetic resin to which a motor 9 and a switch mechanism 11 are fixed, a mounting metal plate 7 fixed to the front case 1 with screws 8, and a mounting metal plate 7. A motor 9 having a connection terminal 10 fixed in a direction protruding rearward, a lead cord 12 such as the switch mechanism 11 having a terminal 13 exposed on a side of the motor 9, and a front end attached to a side of the motor 9. A sub-cover 1 made of synthetic resin having a connection terminal 25 inserted and connected to the terminal 13 and a rear end protruding rearward.
4, a terminal 22 connected to the connection terminal 10 of the motor 9 and having a terminal portion 24 projecting rearward from the rear end, and a terminal portion 24 that is covered from the rear and the rear end portion of the terminal portion 24 and the connection terminal 25 are inserted. And a synthetic resin rear case 2 having insertion holes 26 and 27 protruding rearward and a coupler 29 for inserting a female socket 32 integrally bulging around the insertion holes 26 and 27. Since the connection device for the vehicle actuator is used, the connection between the terminal 13 and the connection terminal 25 and the connection terminal 1 of the motor 9 are performed.
Since the connection between the terminal 0 and the terminal 22 can be monitored with the naked eye, there is an effect that the connection is complete. The present invention also relates to a front case 1 made of synthetic resin to which a motor 9 and a switch mechanism 11 are fixed, a mounting metal plate 7 fixed to the front case 1 with screws 8, and a mounting metal plate 7. A pair of connection terminals 1
The motor 9 is fixed so that the terminal 0 protrudes rearward, the pull-out cord 12 is provided so that the terminal 13 is exposed on the side of the motor 9, and the terminal portion 24 is connected and fitted to the connection terminal 10 so that the terminal portion 24 is rearward. A pair of terminals 22 provided so as to project in parallel to each other, and when attached to the side of the motor 9, the terminals 22 are pressed toward the motor 9 and the front end is inserted and connected to the terminal 13 and the rear end is connected. Is a synthetic resin sub-cover 14 having a connection terminal 25 protruding rearward in parallel with the terminal portion 24, and surrounding the motor 9 from the rear side to allow the terminal portion 24 and the rear end of the connection terminal 25 to pass therethrough. And a coupler 29 for inserting the female socket 32 is integrally formed around the insertion holes 26 and 27 so as to protrude rearward. Since the connection device for a vehicle actuator comprising the rear case 2 made of oil is used, the effect of the above-mentioned item 1 can be achieved as it is, and the use of the synthetic resin sub-cover 14 allows the terminal to be formed by the synthetic resin sub-cover 14. 22 can also be pressed down, and the attachment of the terminal portions 24 and 25 is facilitated.
