Description

[Detailed explanation of the invention] (1) Purpose of the invention (industrial application field) This invention is used in the technical field of holding a multi-pole connector and directing a multi-core cable connected to the multi-pole connector. The present invention relates to a cover case for a multi-polar connector that is used, and particularly allows the multi-core cable to be set in any direction.

(Prior art) As a cover case for this type of multi-pole connector, Japanese Utility Model Publication No. 51-28627 and Utility Model Publication No. 58-109175
The one disclosed in No.

These known cover cases are provided with a plurality of cable outlets, one of which is appropriately selected to guide the cable therein, and the other unused cable outlets are left open or It takes the form of a stopper.

In the case of the above-mentioned known cover case, as mentioned above, there is an increase in the number of parts required for processing other cable outlets that are not used, and the labor involved, or an increase in the cost of the molding die due to the complexity of the shape, and furthermore, there are problems with the structure. For this reason, there were problems in that multiple cable exits were limited to the same plane.

(Problems to be solved by the invention) The present invention solves the above-mentioned conventional problems, has a simple structure, has a single cable exit, eliminates the conventional unused cable exit, and has a three-dimensional structure. To provide a cover case for a multi-pole connector that can selectively orient cables in different directions.

(2) Structure of the invention (means for solving the problems) In order to solve the above problems, this invention accommodates a multi-pole connector and guides the multi-core cable connected to the multi-pole connector. a pair of half-casings that pass through the cable outlet and are split into two parts that can be joined together in a plane parallel to the cable axis at the cable outlet, the cable outlet having: A cable guide extending outwardly in the direction of the cable axis and then bent at a right angle is engaged, the cable outlet and the cable guide forming regular polygons corresponding to each other about the cable axis, The cable guide is characterized in that one side of the cable guide is provided with a locking protrusion and the other side is provided with a locking groove for receiving the locking protrusion.

(Function) To orient the multi-core cable using the cover case of the multi-pole connector of the present invention, proceed as follows.

First, the pair of half-cases of the cover case are separated, and the connector to which the multi-core cable is connected is held at a predetermined position in one half-case.

The cable is guided into a cable guide, which is then engaged with the cable exit portion of the one case half at the desired bending position of the cable. This engagement is achieved by fitting the locking protrusions and locking grooves provided on the cable outlet portion of the half case and the cable guide into each other.

Finally, the other half case is joined to the one half case. This connection is achieved by tightening both half cases with, for example, screws, after engaging the locking protrusions and locking grooves provided on the cable exit portion of the other half case and the cable guide, respectively. .

The cable thus has its orientation selectively set in the desired direction.

Furthermore, if it is desired to guide the cable in the same direction as it is connected to the connector without bending it at right angles by the cable guide, it is sufficient to simply connect the pair of half cases without using the cable guide.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is an exploded perspective view of the cover case of this embodiment, showing a cable guide 3 disposed between a pair of half cases 1 and 2, with the cable guide 3 partially broken.

The cover case of this embodiment consists of the pair of half cases 1 and 2 and a cable guide 3.

The pair of half cases 1 and 2 are provided with a screw hole 11 on one side for connecting the two half cases 1 and 2, and a guide hole 21 on the other side for passing the screw 4 that is screwed into the screw hole 11. It is made symmetrically, with the exception of the fact that the case is split in the middle. Therefore, regarding the shape of the half-cases, only one half-case 1 will be described.

The half case 1 is open at the bottom and on the side to be connected to the other half case, and forms a connector housing space 12 in which half of the multipolar connector 8 is accommodated. A locking step 13 is provided on the inner surface of one side wall of the half case 1 forming the space 12, and when the connector 8 is housed in the space 12, the shoulder 81 of the connector
This locks the connector to position the connector and prevent it from falling off.

In the center part of the ceiling part 14 of the half case 1,
A square groove 15 is provided which forms one half of the cable outlet for attaching a cable guide, which will be described later. The square groove 15 is approximately in the shape of half a square, and triangular corner edges 16, 16 as locking protrusions are left at the corners of the square groove 15.

The cable guide 3 has a groove-shaped cross section formed by three sides of a substantially square shape, and is bent at a right angle to form an elbow shape. As shown in the figure, the cable guide 3 is continuously open at the bottom and the right side bent at right angles, and by disposing the cable inside the cable guide 3, the cable can be reliably bent. I'm starting to do that. The lower end periphery 33 of the cable guide 3 is dimensioned to fit into the square groove 15 described above, and is pressed inward by press molding, and furthermore, a locking groove is formed at the corner by punching. 34 is formed.

The installation of such a cover case is carried out as follows.

First, the connector 8 is placed in the connector accommodating space 12 of one half case 1. At this time, the shoulder section 81 of the connector is engaged with the engagement step section 13 formed on the inner wall surface of the half case, thereby positioning the connector and preventing it from falling off.

Next, a cable (not shown) connected to the connector is guided into the cable guide 3, and the outlet of the cable guide 3 is oriented in a predetermined direction, and the cable guide 3 is inserted into the half case. Insert into the square groove 15 of. This fitting is done by inserting the corner edge 16 of the half case 1 into the locking groove 34 of the cable guide 3.

Next, the other half case 2 is joined to the one half case 1. In this connection, the corner edge of the other half case 2 is connected to the remaining locking groove 3 of the cable guide.
4 and then tightening the screw 4.

The connector is thus held by the cover case with the cable oriented in a predetermined direction (see FIG. 2).

When fitting the cable guide 3 into the square groove 15,
By changing the direction of the cable guide 3, the cable can be directed in the direction of the arrow in FIG. 4 or 5. Furthermore, if you want to extend the cable upward without bending it, you do not need to use a cable guide as shown in FIG. 3.

(3) Effects of the invention The invention as described above produces the following effects.

A cover case with a single cable outlet allows the cable to be selectively bent in each direction simply by changing the direction of the cable guide, making it extremely convenient.

Since there is only one cable exit, there are no unused cable exits, which saves time and effort for post-processing.

Since the shape is simple, the cost of the mold is also reduced.
