Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is a connector that connects a large number of circuits at the same time, such as in computer-related equipment. The present invention relates to a flat cable pressure welding jig that presses two flat cables from both sides and covers the outer surfaces of both flat cables with a pair of covers.

(Prior Art) An inexpensive press-fitting jig for flat cables that can manually press-fit a flat cable to a connector one side at a time is widely known.

As a device of this type, an expensive one with double-sided pressure welding was proposed in Japanese Patent Publication No. 55-25712, which is a wire positioning jig that supports a connector on a positioning jig and can approach both sides of the connector by swinging. and a wire insertion board,
A device is disclosed in which the electric wires are positioned one by one on the jig and each member is pressed toward the contact using the left and right handles.

Furthermore, in the application of Japanese Patent Application No. 1-83230, the applicant previously disclosed a base, a connector holder that holds a connector and is attached to the base so as to be slightly movable in the direction of both sides of the connector; A cable guide that covers the top of the connector and can be opened and moved forward and backward in the longitudinal direction, and has a narrow top, and a holder arm that is pivoted to the base and can be stopped at positions on either side of the connector. , a housing chuck attached to the holder arm and holding the housing; a support surface also attached to the holder arm and supporting one surface of the end edge of the flat cable oriented toward the gap between the housing chuck and the connector; The cable holder includes a locking claw and a locking piece that can move forward and backward in the width direction of the cable with respect to the other surface, and a pair of pressure plates that press the flat cable together with the housing toward the protruding piece. We have proposed a cable connection device for connectors with characteristics.

(Problems to be Solved by the Invention) The invention described in Japanese Patent Publication No. 55-25712 requires a lot of effort to position the electric wire, and it is difficult to balance the left and right forces when pressing the electric wire to the contact. There is a risk that they will not be pressed in the same condition. In addition, the invention described in Japanese Patent Application No. 1-83230, which solves this problem, holds both ends of a flat cable with a cable holder, and uses a pressure plate to hold the cable while preventing it from coming out with a non-return claw. Since the cable is pressed, there is no displacement of the cable relative to the connector, and the connection can be ensured.

Such double-sided pressure welding equipment is expensive. When a flat cable is press-connected to a connector on one side at a time in the prior art, there is a problem in that the flat cable is not clamped sufficiently, resulting in a lack of reliability in press-fitting accuracy. There is also the problem that it takes time and effort to put on the cover by hand.

The present invention has been made to solve the above problems, and its purpose is to connect a flat cable to a connector reliably, and at the same time cover the outer surface of the flat cable with a cable cover. The present invention aims to provide a pressure welding jig for flat cables that can be used for flat cables.

(Means for Solving the Problems) In order to remotely achieve the above object, the present invention arranges the above connector between guide blocks fixed to a locator plate, and attaches left and right locking supports to the locator plate. A flat cable holding plate connected to the left and right arms, each swingably supported on the locking support base, is provided with an elastic member for holding down the flat cable, and one end of each of the arms is provided with the locking support. It is characterized by providing a latch that engages with the base.

Further, it is recommended that the elastic member is a sponge plate.

(Function) By configuring as above, the cable cover dummy is attached to the connector and placed between the guide blocks, the flat cable holding plate is raised upwards, the flat cable is placed on the connector, and the flat cable dummy is placed on the connector. Hold the flat cable with the elastic member of the holding plate, then place the cable cover on top of the flat cable and press it with a hand press. Each core wire of the flat cable is press-fitted into the slit of each contact, and the cable cover is attached to the flat cable. It is covered and attached to the connector.

Next, remove the cable cover dummy, turn the connector over and place it between the guide blocks, similarly hold the flat cable placed on the connector with the elastic member of the flat cable holding plate, and then place the cable cover on the flat cable. When placed on top and pressed with a hand press, each core wire of the flat cable is press-fitted into the slit of each contact, and the cable cover is placed over the flat cable and attached to the connector and the opposing cable cover.
