DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of an L-shaped multi-core cable connector most suitable for use as a wiring means on the back side of various electronic devices such as a computer device.

[0002]

2. Description of the Related Art Conventionally, as an example of a multi-core cable connector, for example, an Amphenol D-SU used as an input terminal of various electronic devices such as a computer device.
There is a B connector of a 14-pin type, in which 14 covered conductors of a multi-core cable are connected to conductor press-contact portions of 14 connector terminals of a connector body. And this kind of conventional multi-core cable connector is connected to the connector buried on the back side of various electronic devices by being wound horizontally by the connector main body and connecting the multi-core cable horizontally to the back side of the connector main body. It is something to be drawn out.

[0003]

However, in a multi-core cable used in a conventional multi-core cable connector of this type, a conductor for grounding is wound around an outer periphery of a large number of, for example, 14 coated conductors in a cylindrical shape. In addition, the outer periphery of the multi-core cable is configured with a multi-core structure, and the multi-core cable has a large diameter and low flexibility (poor). In a state where the multi-core cable is wound and connected, the multi-core cable is pulled out horizontally over a long distance to the back side of the various electronic devices, and a large wiring space for wiring the multi-core cable is required. There was a problem to say that.

Japanese Patent No. 2889653 discloses an L-type coaxial cable connector in which an outer conductor and a center conductor of a coaxial cable are soldered at right angles to an outer contact and a center contact of a connector body. However, in a multi-core cable connector using a multi-core cable in which a number of coated wires such as 14 are inserted in an insulating tube, a large number of coated wires of the multi-core cable are connected to a number of connector terminals of the connector body at right angles. The work is very complicated when it is attempted to solder in a shape. That is, many connector terminals of the connector main body are arranged close to each other at a small interval, and it is extremely difficult to solder the coated conductors to the connector terminals one by one so as not to short-circuit the connector terminals. Then, in order to ensure reliability, it is necessary to increase the interval between a large number of connector terminals, and in particular, there is a problem that a multi-core cable connector based on predetermined specifications cannot be realized.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. In a multi-core cable connector in which a large number of coated conductors need to be connected to a large number of connector terminals, a wiring space for the multi-core cable is reduced. It is an object of the present invention to provide an L-shaped multi-core cable connector that can save space.

[0006]

To achieve the above object, an L-shaped multi-core cable connector according to the present invention is a multi-core cable in which a large number of covered conductors of a multi-core cable are connected to a large number of connector terminals of a connector body. In the connector, a cable guide portion is integrally formed at a substantially right angle integrally with an end of a connector cover portion covering an outer periphery of the connector body, and a multi-core cable is drawn in a substantially right angle shape in the cable guide portion. .

In the L-shaped multi-core cable connector of the present invention configured as described above, a cable guide portion is integrally formed substantially at right angles integrally with an end of a connector cover portion that covers the outer periphery of the connector body, and a large number of coatings are formed. The multi-core cable with the conductors connected to the many connector terminals of the connector body was pulled out in the cable guide part by bending it approximately at right angles, so that the many coated conductors of the multi-core cable were connected to the many connector terminals of the connector body as before. The multi-core cable can be pulled out of the connector body in a substantially right-angled manner.
