Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electrical connector in which the terminal end of a group of conducting wires, such as a flat cable or an east wire, is accommodated in a housing.

(Prior Art) Conventionally, as electrical connectors in which multi-core wires are housed in a housing, one for flat cables and the other for East Line are known, but both ministries are using the IM construction.

However, when considering economic efficiency, it is necessary to avoid manufacturing the parts used for both F and securing the door for each. η
There is a need for a connector that can At the same time, such connectors should be able to be converted from one application to another to suit the application with a minimum of manipulation and minimize distortion of the coupe depending on the local circumstances of that application. is desired.

US Pat. No. 3,856.376 discloses an electrical=1 connector that can be adapted to a multi-conductor conductor of a certain size.

This electrical connector includes an insulating housing consisting of a pair of shells each having a connector surface and a conductor receiving surface;
A conductor fixing member having first and second conductor fixing surfaces having a curved shape, the conductor fixing member being stored inside when the pair of shells marked -F are combined. The conductive wire group corresponding to the first and second fixing portions is fixed by one of the surfaces of the first and second fixing portions formed on the opposite surface of the conductive wire member. This group of conductive wires is inserted into the shell from the wire receiving surface mentioned above and connected to the terminal arranged on the connection surface marked J8.

However, the electrical connector described above has a relatively complicated structure and requires a long time to assemble. In particular, when assembling the housing, there is a problem in that it takes a long time to assemble the housing because the negative phase clamping screw is tightened to reduce the distortion of the conductor. was there.

(Object of the Invention) The present invention provides a flat cable that is easy to assemble and can apply a conductor clamping pressure that is appropriate to the situation.
The purpose is to provide an electrical connector for common use on the East Line.

<Groove Bottom of the Invention) The electricity = 11 netata of the present invention, which can be used for any of the flat cable and the east line, is provided with a pair of conductor fixing members of the same shape in the housing, and this conductor fixing member is provided in the housing. A conductor pusher rib extending along the first edge of the first conductor fixing surface of the member is arranged parallel to the conductor when the housing is assembled, and this material is arranged in parallel with the conductor when the housing is assembled. When used for a cable, the first fixing surfaces of the inner conductor fixing member are arranged so as to sandwich the flat cable and face each other, and the ribs are arranged against each other in the direction in which the flat tour pull extends. The flat couple is clamped and fixed by this device, and when this netata is used for the East Line, the second fixing surface of the inner conductor fixing member is The two members are arranged to face each other with the wire bundle in between, and the notches of both members are combined to form an east line receiving opening.

Note that it is more preferable to form the ribs into a hook shape, since this allows the slack of the flat cable to be taken care of.

Further, it is more preferable to provide a guide for fixing the position of the conducting wire fixing member in the housing, since this allows the member to be properly positioned with respect to the conducting wire when assembling the housing.

(Effect of the invention 'A!) According to the electrical connector of the present invention, a pair of conductor fixing members are installed, and this conductor is fixed. Either the front side or the back side of the month A will be the first fixing surface for fixing the flat couple, the other side will be the second fixing surface for fixing the east line, and either surface can be attached to the other side depending on the purpose. Opposed to me! Because the conductor is sandwiched, the flat couple and the east line share electricity.
11 and 7 can be used, improving economical efficiency.

Further, since the ribs are arranged alternately with respect to the flat cable, the flat cable is formed in a wave shape.

In this state, if tension is applied to the flat cable due to vibration etc., the pressing force of the fixing member against the flat cable will increase, and this can reduce distortion of the flat cable, so it is recommended to use a member with a complicated structure. This makes it possible to quickly reduce the slack in the flat cable.
