The present invention relates to a process for the production of assembly carrying parts connector components you and connector device reduced to the line.

[0002]

2. Description of the Related Art Conventionally, a motor connector device, for example,
2. Description of the Related Art There is a connector device for power supply such as a wiper motor with worm speed reducer in which a plurality of terminals are vertically arranged and arranged in a row so as to face each other.

In this case, each terminal is connected to the motor body side using a lead wire, and each lead wire is insulated by mounting an insulating material such as a varnish tube. There is.

[0004]

In the above-mentioned conventional connector device, when a plurality of terminals are vertically arranged and arranged in a row so as to face each other, each terminal is manufactured as a single item and assembled. Will be brought into the line,
In this state, each terminal must be carried into the assembly line, which increases the number of parts carried into the assembly line and the number of carrying-in steps.
Furthermore, connect each terminal to the motor body with lead wires,
Moreover, since the varnish tube is used for insulation, there is a problem that assembly is complicated and automation is difficult.

Therefore, by arranging a plurality of terminals on one plane and arranging the wide surfaces thereof side by side in the width direction, a plurality of terminals with leads are manufactured as an integral part and carried into an assembly line. By cutting and separating the integrated terminals into multiple parts on the assembly line, it is conceivable to reduce the number of parts to be carried in and the number of carrying-in steps, and also to simplify the connection between each terminal and the motor body. .

By the way, when a plurality of such terminals are arranged on one plane and their wide surfaces are arranged side by side in the width direction,
The space in the width direction becomes large, and in some cases, it may not be desired to take much space in the width direction.

In such a case, it is possible to reduce the space in the width direction by stacking a plurality of terminals in the direction perpendicular to the wide surface. When stacking a plurality of terminals in this way, it is necessary to insert an insulating member between the stacked terminals to insulate the stacked terminals from each other. As a result, the number of carrying-in parts and the number of carrying-in steps increase.

The present invention has been made by paying attention to the above-mentioned conventional problems, and an object thereof is to reduce the number of parts to be carried in to an assembly line and also to reduce the carrying-in process, thereby facilitating automation. It is to provide a method of manufacturing a connector component Contact and connector device.

Further, terminals 42 a and 42 b for connection with the motor body 12 are attached to the end portion of the housing portion 30 on the motor body 12 side.

In addition, the first terminal layer 26 and the second terminal layer 2
The insulating member 40 interposed between the first terminal layer 2 and
6 and the second terminal layer 28 are required to be laminated. If the insulating member 40 is used as a single component, the number of components is increased and the number of components to be carried into the assembly line is increased. The number will increase.

Therefore, in the present embodiment, as shown in FIG. 1, the insulating member 40 is integrally molded with the gear cover 18 in advance when the gear cover 18 is manufactured, and the gear cover 18 and the insulating member 40 are combined into a single connector component 50. By doing so, the gear cover 18 and the insulating member 40 are carried in as one component at the time of loading into the assembly line, and the number of loading components and the number of loading steps are reduced. Then, the insulating member 40 integrated with the gear cover 18 is cut and separated at the time of assembling to separate the terminal mounting portion 38 of the gear cover 18.
I am trying to install it on.

Also, as shown in FIGS. 2 and 3, the insulating member 40 is a gripper 44 (see FIG. 1) as a conveying means in the assembly line on the outer peripheral surface of the storage cover 20.
Is connected to and integrated with the non-contact portion 46 with the gripper 44 except for the area that contacts the gear cover 18 when the gear cover 18 is conveyed, so that it does not interfere with the conveyance.

In this case, the gear cover 18 of the insulating member 40
Since the connecting portion 48 with is a non-contact portion with other parts when it is assembled to the terminal mounting portion 38, even if burrs and the like at the time of cutting remain after cutting and separating, there is no need for assembling. Since there is no obstacle, there is no need to carry out deburring work.

Next, as shown in FIG. 6, the insulating member 40 cut and separated from the gear cover 18 in FIG. 5 is assembled on the first terminal layer 26 assembled in the terminal mounting portion 38.

It is in a state where it does not come into contact with a, 26b, 26c, the wall surface of the terminal mounting portion 38, or the like.

Then, after the insulating member 40 is assembled on the first terminal layer 26 as shown in FIG. 6, as shown in FIG.
The second terminals 28 a and 28 b forming the second terminal layer 28 are assembled and laminated on the insulating member 40.

In this case, the second terminal layer 28
The terminals 28a, 28b of the first terminal layer 26 are integrally formed in advance and carried into the assembly line as one component, as in the case of the first terminals 26a, 26b, 26c forming the first terminal layer 26. It is cut and separated on the attachment line and assembled on the insulating member 40.

Further, these second terminals 28a, 28b
Since the wide surfaces are arranged side by side in the width direction on one plane and the lead portions are integrally formed, it is possible to assemble without performing the lead wire connection work or the like. It has become.

In this way, the first terminal layer 26 and the second terminal layer 28 are laminated, and insulation is provided between the first terminal layer 26 and the second terminal layer 28 by using the insulating member 40. In spite of this, the number of carrying-in parts to the assembly line can be reduced, and the number of carrying-in steps can be reduced. Since the connector component 50 is transported to the step of assembling the insulating member 40, the number of transport steps can be reduced.

Further, since the insulating member 40 is provided in the non-contact portion 46 with the gripper 44 for carrying, it does not interfere with the carrying, and the connecting portion 48 of the insulating member 40 with the gear cover 18 is provided. Since it is a part that does not contact other parts during assembly, assembly can be done easily without performing work such as deburring after cutting, and generation of dust after deburring can also be prevented. .
