[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector structure for connecting an electric wire / cable terminal to an input / output terminal of a motor mounted on an electric vehicle or an input / output terminal of general equipment.

[0002]

2. Description of the Related Art Generally, an electric wire / routed from a power source
When connecting the end of the cable to the input / output terminal on the device side,
There are many structures in which terminal fittings such as a flat terminal called an LA terminal crimped to an electric wire / cable end are fastened together with a device connecting terminal with a bolt. On the other hand, as an example of a special structure of terminal fittings that replaces flat terminals, the conductor of the wire / cable end is crimped on one side, and the "female screw" formed on the other side is screwed with a bolt to connect to the device side. It may be fastened to the terminal.

As such a terminal fitting with a female screw, for example, the actual open flat 6-58 previously proposed by the applicant of the present application.
There is one disclosed in a shield connector directly attached to a device described in Japanese Patent No. 560. This will be schematically described with reference to FIG.

As a device example, a drive motor mounted on an electric vehicle is disclosed, and a flat plate terminal 2 is crimped to the end of a power supply connecting cable 1 drawn from the motor. In addition, in this case, the power supply wire / cable that has been routed from the power supply battery mounted on the vehicle to the vehicle body is shown as the shielded wire 3, and the terminal metal fitting 4 is attached to the conductor 3a exposed by peeling off the shielded wire end. It is crimped at one end. On the other hand, a shield connector 6 is fixed with bolts 7 using a metal motor outer plate case 5 as a body to be attached. Through the shield connector 6, the flat plate terminal 2 of the motor side cable terminal and the power source side shielded wire terminal are connected. Terminal fittings 4
Is connected to each other to achieve electrical conduction.

In this case, the terminal fitting 4 has the conductor 3a on one end side.
Is crimped, and a female screw 4a is threaded on the other end side. Therefore, by inserting the bolt 8 into the flat plate terminal 2 of the terminal of the motor side cable 1 and screwing the bolt 8 into the female screw 4a of the terminal fitting 4, the flat plate terminal 2 and the terminal fitting 4 are
Fasten and connect.

[0006]

By the way, in the previously proposed shield connector directly attached to a device shown in FIG. 5, the terminal metal fitting 4 with the female screw 4a is used as a connection terminal of the shielded electric wire 3 routed from the power source. Since it is used, improvement is desired in the following points.

Is what you are doing. At that time, if the flat plate terminal 2 or the peripheral member has a positional deviation or an error in dimensional accuracy on the motor side, or if each member such as the terminal fitting 4 has an error in dimensional accuracy or assembly on the connector housing 6a side, such an error is generated. There is little freedom to absorb. As a result, when the bolt 8 is screwed into the female screw 4a, fastening the flat plate terminal 2 and the terminal fitting 4 takes time, which may make the assembly work difficult.

First, the terminal fitting 4 has a portion for crimping the wire conductor 3a on one end side thereof, and the female screw 4 on the other end side thereof.
Since a is threaded, the number of manufacturing steps increases and the component cost rises regardless of whether the threading is machining by cutting or forging by rolling.

In order to solve the above problems, an object of the present invention is, for example, to connect a power source side electric wire / cable terminal to a motor terminal mounted on an electric vehicle through a connector,
The accuracy error between the members is absorbed to improve the efficiency of assembly work,
Another object of the present invention is to provide a wire / cable connector structure that can reduce the manufacturing cost of terminals at low cost.

In order to fix it to the housing, various components for electromagnetic wave shielding such as a shield shell 14 and a braid fixing ring 15 are mounted on the housing 11 of the connector.
When the plate terminal 24 on the electric wire side is displaced from the initially set position due to an error in the dimensional accuracy or the assembly accuracy of the holding member or the shield component, the position deviation of the bus bar 33 is absorbed to absorb the positional deviation. Connection work with the connection terminal, for example, the flat plate terminal 31, can be performed without any trouble.

The above construction is particularly effective in the connector structure for connecting the electric wire / cable from the power battery to the motor mounted on the electric vehicle. That is, in this case, the mounted body 40, which is a member for mounting and fixing the connector, is a metal motor outer plate case grounded to ground. The housing 11 fixed to the motor outer case 40 while ensuring oil proofness is an insulator. For example, a resin molded product can be used as the insulating housing 11. Therefore, it becomes possible to provide the error absorbing concave portion 18 by resin-molding the housing shape into an arbitrary shape. On the other hand, even if there is an error in the molding accuracy because it is a resin molded product, the position adjustment of the fastening part using the bolt and nut between the flat plate terminal 24 which is the wire / cable connecting terminal and the bus bar 33 is absorbed by the error.
