Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended to prevent mistakes in the arrangement sequence when connecting a multi-core cable used for wiring of a computer and various electric devices to a connector. The present invention relates to an electric wire holder that can hold individual electric wires in a separated state.

[Prior art]

Generally, a multicore cable for signals is used for internal wiring of electronic computers and various electrical equipment, or for internal wiring of industrial equipment and connections between electrical equipment, and a connector is connected to the end of the cable. .

This multi-core cable, which is used in small electronic computers and word processors, is usually an assembly of 16 (8 twin) or more electric wires, and one or both ends are connected to a connector. However, it is always necessary to make sure that the wires are arranged in the correct order. In addition to the case of a single electric wire, depending on the application, there are a plurality of electric wires twisted into a single electric wire. For example, a large number of electric wires are accommodated in a single covering such as a telephone cable. In that case, it is not an easy task to make sure that the arrangement order is correct.

Although the wires that make up a multi-core cable are colored so that they can be easily distinguished from each other, as described above, in the case of a large number of wires, the correct order must be confirmed within a short time by color coding. Is difficult. Also, after connecting the connector to the end of the multi-core cable, it is always necessary to check whether the connection between the two connectors is correct.

Also, in some cases, in order to identify the electric wires, a mark band is attached to each wire and then soldered, and after confirming that there is no mistake, the work of removing the mark band is performed.

Therefore, in order to facilitate the work of connecting the multi-core cable to the connector, for example, the electric wires are arranged in a sheet according to the arrangement of the connectors, a supporting plate is applied to the back surface of the electric wires, and the individual electric wires are connected with a thread. Has adopted a method that facilitates connection work. However, in this method, it is necessary to carefully arrange the individual electric wires so as not to mix, and to tie them on the support plate using one thread so that this order is not disturbed, and the work is extremely complicated. It was a thing.

Further, as a means for holding a plurality of electric wires in parallel, a "electric wire clamp" of Japanese Utility Model Laid-Open No. 56-117473 has been proposed, but the electric wire holder (clamp) according to the present invention has a large thickness. Although it has a plate-like shape and is provided with a plurality of electric wire holding grooves on one side thereof, it can be bent only in its thickness direction. This electric wire holding plate is not originally intended to arrange and hold electric wires, but is a component for tightening and fixing electric wires incorporated in a wiring box, and it is possible to peel, cut, and connect electric wires at the same time. It's the purpose. And
Because the direction of structural deformation is limited, it is not possible to hold the sheath of a multi-core cable or a plurality of drawn wires on a flat surface near the excised portion of the sheath and arrange them in an organized state. Is. Furthermore, in order to hold and release the electric wire, it is necessary to bend the entire electric wire holding plate and then insert or pull out the electric wire. There are problems such as badness.

In addition, there is an idea of a "multiple connector" proposed in Japanese Utility Model Publication No. 54-150896, but the wire holder (connector) according to the present invention has holes for inserting terminals and wires in the upper and lower terminal surfaces. The provided housings are connected at their terminal surfaces with a pleated connecting plate so that the distance between the housings can be adjusted slightly. However, this is originally a component of a printed wiring board, and since it absorbs the error on the terminal side, the spacing between the housings can be adjusted slightly, and the flexibility is poor. It is impossible to hold a plurality of electric wires drawn out from the body in a state in which they are spread and arranged on a plane near the cut portion of the covering body. In addition, especially in that the wire end has to be fitted in the hole on the end surface of the housing,
There is a problem in that it is impossible to perform a necessary step in arranging several electric wires and holding the electric wires in the longitudinal direction.

Further, there is an idea of "structure of a simple terminal display device" proposed in Japanese Utility Model Publication No. 48-114074, but the electric wire holding plate constituting this device is provided with a protruding holding claw on itself,
A plurality of grooves are provided in parallel. However, since this wire holding plate cannot be bent in its width direction, the holding plate lacks flexibility, and like the above, the wire cannot be held in a state in which it is spread on a flat surface near the cut portion of the covering and arranged. I have a problem.

[Purpose of device]

The present invention has been achieved in order to solve the problems of the conventional multi-core cable holder, and a plurality of electric wires drawn out from the multi-core cable are spread and simply arranged in a fan-shaped arrangement. An object of the present invention is to provide an electric wire holder or an electric wire connection preparation tool capable of holding and soldering or other wiring work quickly and easily without connection mistakes.

[Constitution of device]

In order to achieve the above object, an electric wire holder according to the present invention comprises:
An electric wire holder capable of expanding and holding a plurality of bundled electric wires in a fan-shaped arrangement, wherein a plurality of holding members have a slight distance from each other by a connecting body arranged near one end thereof. The holding member has a cylindrical shape with a C-shaped cross section and has a narrow opening in the upper surface longitudinal direction.
The connecting body is configured so that its length is shorter than the length of the holding members and is flexible so as to allow movement between the holding members, and these are integrally molded integrally with synthetic resin. ing.

Since it is configured as described above, the coating of the multi-core cable is peeled off, and the exposed and expanded plurality of electric wires are arranged and arranged to maintain the arrangement state. When it is pushed into the opening of the holding member of the holder, it is easily fitted and held.

The wire holder is designed to accommodate the movement of the wire to be held and changes in the vertical and horizontal directions during the work of holding and sorting the wires, and the fan-shaped expansion of the holding member can be expanded or contracted, and even vertically. You can easily work by changing and following.

The holding member can hold any position in the longitudinal direction of the electric wire, but since it can hold the electric wire by expanding it in a fan shape with its connecting body side as a fulcrum, it can be used near the base of the covering body to expand the electric wire. Since the electric wire can be held near the starting point, the exposed length of the electric wire, that is, the stripping length of the cable sheath, can be extremely short.

When a very large number of electric wires are accommodated in the cover like a telephone cable, a plurality of electric wire holders are used to expand the width of the electric wire holders in a width direction and adjust the width freely, so that a large number of electric wires are fan-shaped as a whole. Hold it in a flat plate shape, or stack the wires one after another with the wire holders slightly offset.
It is compact in plan view, and the overlap is not high and there is no confusion,
It can be sorted neatly.

The wire holder is designed to accommodate the movement of the wire to be held and changes in the vertical and horizontal directions during the work of holding and sorting the wires, and the fan-shaped expansion of the holding member can be expanded or contracted, and even vertically. You can easily work by changing and following.

Next, after performing the same procedure as above on the cable on the opposite side, wire the wires one after another.While this wire connection work, the holding member The fan-shaped expansion expands or contracts, and the direction is changed to follow the upper and lower steps, so that the wiring work can be performed very easily.

After wire connection, if one end of the wire holder is pulled, the wire is released from the opening of the holding member, and the wire holder can be easily removed. However, in some cases, the electric wire holder is flexible and not bulky, so there is no particular problem even if the electric wire is covered with the electric wire attached to the electric wire without removing it.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a front view of the electric wire holder 1, and FIG. 2 is II of FIG.
-II shows an arrow view, and FIG. 3 shows a partially enlarged view of FIG.

The electric wire holder 1 is configured by connecting a plurality of holding members 2 each having a slit-shaped opening 3 in parallel with a connecting body 4, and is wholly integrally molded of synthetic resin.

The holding member 2 is formed in a substantially cylindrical shape, the inner diameter D is made slightly larger than the diameter of the electric wire, and is slightly different depending on the thickness of the electric wire, but in this embodiment, it is about 2 mm and the length L is about 8 mm. To do. The opening size S of the slit-shaped opening 3 is
The cross-sectional shape of the opening is approximately V-shaped so that the electric wire 9 can be easily fitted thereinto. When the electric wire 9 is inserted from the opening 3 as described above, the electric wire 9 is held by the holding member 2.
Then, it is once supported by the opening 3 and reconfirmed, and then the elastic force of the opening edge 2'is used to push it in and hold it. At this time, since the opening side of the holding member 2 is thin and the portion from the center to the bottom is formed thick, the expanding / contracting operation of the upper portion is facilitated and the labor is saved.

As shown in FIG. 1, the connecting body 4 connecting the holding members 2 connects only one end of the holding member 2 and does not connect the other end portion 5. The connecting body 4 is formed to be shorter than the length of the holding member.

This provides the connecting body 4 with sufficient flexibility, and as shown in the plan view of FIG. 4, a large number of electric wires 9 taken out from the multi-core cable 8 are fanned out in a relatively short distance. This is for holding and allowing the terminals 10 of the connector 10 to be expanded substantially in accordance with the arrangement interval. In the wire holder 1 formed as described above, as shown in FIG. 4, the wires 9 are inserted in accordance with the arrangement order of the terminals 11 of the connector 10, and the tips are spread out in a fan shape to form the wires 9. Since they are arranged in a flat plate shape in the order of attachment so that they can be easily handled, they can be easily connected to the terminals 11 by soldering or the like.

If the holding member 2 or the connecting body 4 or the like is provided with a code or a mark matching the arrangement order of the terminals 11, the connection accuracy is further improved. As shown in FIG. 5, when the electric wire holder formed as described above accommodates an extremely large number of electric wires 31 in the covering such as the telephone cable 30, the electric wire holders 32 and 33 are used to connect the electric wires. If the electric wire holders 32 and 33 are sequentially shifted in the width direction and the longitudinal direction while being slightly shifted, they can be sorted compactly in a plan view without causing a high overlap and confusion.
