Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cable connection device for connecting terminals of interface cables, etc. of computers, etc., and in particular, to a cable connection device for connecting terminals of interface cables, etc. of computers, etc. The present invention relates to a cable connection device suitable for connection to a terminal of the present invention.

[Conventional technology]

Conventionally, the techniques for connecting multicore cables with multiple wires to connector terminals include soldering, screw tightening,
Techniques such as crimping have been used.

Recently, in order to reduce the number of connections required, pressure-contact type connectors have been widely used in which the wire is press-fitted into the slot of the terminal, penetrates the insulator, and makes contact between the wire conductor and the terminal to maintain continuity. It's becoming more and more difficult. In the case of this method, specified electric wires are arranged in accordance with the pitch of the terminals provided on the connector housing, and then the electric wires are press-fitted all at once into the slot portion using a press or the like.

By the way, in conventional devices of this type, when connecting multiple wires to each terminal of a connector, as described in Japanese Patent Publication No. 61-8557, the correspondence between wire numbers and terminal numbers is After the wires were connected to the terminals, the connectors at both ends were tested by probing them with continuity tefters, etc.

[Problem that the invention seeks to solve]

In the case of the above press-fitting method, if unspecified wires are press-fitted due to incorrect wiring, etc., it will not be possible to pair only the incorrect wiring, and the entire connector will need to be remanufactured, resulting in loss of one part and remanufacturing. Misalignment becomes a serious problem as it increases the number of man-hours required.

However, as mentioned above, the conventional cable connection method A is configured to check the correspondence between the wire number and the terminal number by probing the connector at both ends with a continuity tester after connecting the wire to the terminal. Therefore, there was a problem in that it was not possible to efficiently check the correspondence between wire numbers and terminal numbers before connection.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in the conventional cable connection bag (4) and to efficiently correspond the wire number and terminal number before connection. An object of the present invention is to provide a cable connection device that allows for accurate checking.

[Means for solving problems]

The above object of the present invention is to provide a cable connecting device for connecting a plurality of electric wires to a connector, including a wire guide block that simultaneously arranges both ends of the plurality of electric wires corresponding to each terminal of the connector; This is achieved by a cable connection device characterized in that it is provided with a probing terminal for continuity check disposed opposite to the cable connection device.

[Effect]

In the present invention, both ends of the cable to be connected to the connector are arranged at the same time, and before the multiple wires of the cable are press-fitted into the connector terminal at once, the wires at both ends are probed with the terminal of a continuity tester to check the arrangement order. If there is no misalignment, press-fitting is performed all at once.

The wire arrangement section is configured so that both ends of the wires can be arranged simultaneously in correspondence with the connector terminals.

The press section has a pilot pin for positioning the wire arrangement section, a continuity probing terminal, and a suppression header section for press-fitting the wires all at once into the slots of the connector terminals so that check terminals for continuity testing can be probed at both ends of the wires. ing.

The drive of the continuity probing terminal and the drive of the suppression header are independent, so after checking the arrangement order, the wires can be press-fitted into the slots of the connector terminal all at once. can be prevented from occurring.
