JPH0556536A - Formation of connector unit having l-type cable connector - Google Patents

Abstract

PURPOSE:To arrange the direction of L-type connector correctly and automatically by forming a linear mark or an index on the surface of cable sheath or outer semiconductor layer and fixing L-type connectors to the opposite ends of the cable. CONSTITUTION:A central cable conductor 11 is coated with a cable insulator 12, an outer semiconductor layer 13 of cable, and a cable sheath 14. A linear mark 131 is printed in the longitudinal direction of cable on the outer semiconductor layer 13 or an index, e.g. a protrusion, is formed in the longitudinal direction of cable at the time of extrusion coating of the outer semiconductor layer 13. When L-type connectors are fixed to the opposite end of the cable, L-type connectors 2A, 2B are fixed with reference to the linear mark 131 while matching the direction thereof. According to this invention, direction of L-type connector can be matched easily without requiring additional work or a jig.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting method for attaching an L-shaped connector to both ends of a cable for connecting electrical equipment by processing it in advance.

[0002]

2. Description of the Prior Art Referring to the drawings, the cable ends will be L
An example of a cable in which a shape connector is processed will be described. In FIG. 4, L-shaped connectors 2A and 2B are provided at both ends of the cable 1.
It shows a state where is attached. The L-shaped connectors 2A and 2B at both ends are L-shaped according to the other electrical equipment to be connected.
It is necessary to determine the orientation of the shaped connectors 2A and 2B and attach them.

Here, for convenience of explanation, L-shaped connectors 2A and 2B are used.
A case will be described in which the processing is performed by matching the directions of. FIG. 5 shows a case where the directions of the L-shaped connectors 2A and 2B deviate by θ degrees. If this is not matched, the cable will be twisted and therefore must be processed to match.

[0004]

As described above, in order to match the directions of the L-shaped connectors 2A and 2B, the following serious work is required. First, the cable 1 generally has a curl, etc., which is straightened and one L-shaped connector is attached, and then the other L-shaped connector is attached.
When mounting the shape connector, various troublesome means are required to make the angle θ shown in FIG. 2 as small as possible.

As means for this, there are a method of visually matching and a method of fitting and attaching jigs and tools whose both ends are in the same direction. This is cumbersome and inefficient for the work, and the accuracy of adjusting the angle θ is low.

The present invention has been made in view of the above circumstances, and when processing the L-shaped connector at both ends of the cable, the direction of the L-shaped connector at both ends can be easily changed without using additional work or jigs. Can be matched to L
An object of the present invention is to provide a method for forming a shape connector.

[0007]

According to the present invention, in a connection unit in which L-shaped connectors are provided at both ends of a cable, a straight line mark or mark is formed on the sheath surface of the cable or on the outer semiconductive layer, and the L mark is formed at both ends of the cable. A method for forming a connection unit having an L-shaped cable connector, characterized in that the L-shaped connectors at both ends are processed in a desired direction by processing the L-shaped connector.

[0008]

[Function] By using a cable in which an outer semiconductive layer of the cable to be used or a surface of the cable sheath is provided with a mark such as a color-coded linear mark or a protruding streak, the L mark on both ends is followed according to the linear mark or the marker. As the mounting process is performed by matching the direction of the shape connector, it is automatically and accurately L without any additional work or jigs and tools.
It is possible to match the orientations of the shape connectors, and the efficiency is greatly improved.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 are perspective views showing a configuration of a cable in which L-shaped connectors are attached to both ends in a state in which end states are stripped off. That is, the outer periphery of the central cable conductor 11 is covered with the cable insulator 12, the cable outer semiconductive layer 13, and the cable sheath 14.

In FIG. 1, a linear mark 131 is formed by printing on the cable outer semiconductive layer 13 in the cable length direction, or a mark such as a protrusion is formed in the cable length direction during extrusion coating of the outer semiconductive layer 13. It was provided by. The straight line mark or mark may be formed by a discontinuous mark or mark such as a dotted line or a character pattern, instead of forming a continuous line or a linear body as shown in the drawing.

In FIG. 2, a straight mark 141 is formed on the cable sheath 14 by printing in the cable length direction, or a protrusion is formed on the cable sheath 14 at the time of extrusion coating of the cable sheath to provide a mark. The linear mark 141 may be formed so as to be conspicuous with ink or the like having a different color from the cable sheath 14. Also in this case, the straight line mark or sign may be formed by a discontinuous mark or sign such as a dotted line or a character pattern, instead of forming a continuous line or a linear body.

In order to attach and process L-shaped connectors at both ends using these cables, the linear mark 131 on the cable sheath 14 is used as a mark as shown in FIG. The mounting process is performed so that the connectors 2A and 2B are oriented in the same direction.

Therefore, the directions of the L-shaped connector can be completely matched at both ends, and the directions of the L-shaped connector can be matched very easily without using additional work or jigs.

In the above example, the L-shaped connectors mounted on both ends are aligned in the same direction.
When mounting the connector in a tilted manner, the required angle is determined on the basis of the sign. When it is desired to attach the mark accurately, if the marks such as the linear marks are formed in two different colors at the desired angle, the angle can be accurately set in the same manner.

[0015]

As described above, according to the method of forming the L-shaped connector of the present invention, the L-shaped connector may be attached to both ends of the cable based on the mark such as the straight line mark of the cable, so that the cable has a winding tendency. Even if it is attached, it can be processed without straightening. Also, even if you attach the L-shaped connector to one end of the cable and then attach the L-shaped connector to the other end, you can attach it according to the marking of the cable, so you do not need to check the orientation of both ends individually, Can be attached to. Further, with the above advantages, there is no need to use jigs and tools, and the efficiency of attachment can be improved. As a result, the L-shaped connectors on both ends are aligned in the same direction, and the accuracy is more accurate.
