Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric wire with a protector that is used in the same way as ribbon electric wires such as twist flat cables and sagging cables.

Conventional Technology Conventionally, when connecting single coated wires to multi-pole connectors, the method of press-connecting each wire one by one was extremely inefficient, so in order to improve efficiency, Ribbon wires such as those described above are coming into use. The manufacturing methods for such ribbon wires include arranging a large number of covered wires at a constant pitch and fixing them by melting the covering material and adhering them to each other, or by coating the lined covered wires with synthetic resin such as vinyl. There were methods such as covering it with and fixing it. Also, Mikiakiaki
As disclosed in Japanese Patent No. 57-45112, in order to facilitate connector attachment, a plurality of parallel single wires are connected together with connecting tape at appropriate intervals. A similar cable has been proposed.

Problems to be Solved by the Invention In the conventional ribbon wire manufacturing method described above, a means for accurately arranging a large number of coated wires at a certain pitch is required, which requires a lot of work, melting, and
A mold for coating with vinyl or the like is also required, which causes many problems in processing, and as a result, this type of ribbon wire has become expensive.

In addition, in the conventional cables mentioned above that facilitate connector attachment, the position where the single wires arranged in parallel are integrated is fixedly determined by the position of the connecting tape, and this position cannot be changed. It is not possible. Therefore, even if it is possible to connect the connector at the position of the connecting tape, the connection position of the connector with respect to the cable cannot be freely selected. Also,
Connecting tape in locations where connectors do not need to be connected must remain stuck to the cable even though it is not needed, which is not only wasteful, but can sometimes cause the connecting tape to attach to the cable. It is also possible that being stuck is a hindrance. Moreover, even if the connector can be connected at the position of the connecting tape, the connecting tape does not sufficiently protect the connecting portion of the connector.

An object of the present invention is to provide an electric wire with a protector that can solve the problems of the prior art as described above.

Means for Solving the Problems The electric wire with a protector according to the present invention includes a plurality of insulated electric wires arranged in parallel, and a protector attached to the insulated electric wires so as to be detachable from the insulated electric wires and movable along the insulated electric wires. a plurality of protectors arranged at intervals along the line and holding the covered wires in the parallel arrangement, each of the protectors including a base, and the base body A plurality of holding members are arranged adjacently at corresponding positions on both sides so as to create an insertion space for receiving and press-fitting each of the covered electric wires, and the rows of holding members on both sides are The holding members each have a plurality of openings at positions corresponding to the covered wires arranged in parallel to receive the tips of the press-contacting parts of the contacts of the connector. A portion is formed, and the shape of the protruding portion guides the press-fitting of each covered electric wire into the insertion space and prevents each covered electric wire press-fitted into the insertion space from coming out from the insertion space. When a connector is coupled to any one of the protectors, the tip of the press-contact portion of each contact of the connector breaks the sheath of each corresponding covered wire held by the protector. The protector is characterized in that, by protruding into the corresponding openings, the insulation displacement connection between each covered wire and each contact is performed, and at the same time, the protector functions as a protection member for the connector.

Embodiments Next, the present invention will be described in more detail with regard to embodiments of the present invention based on the accompanying drawings.

FIG. 1 is a perspective view schematically showing an electric wire with a protector as an embodiment of the present invention. As shown in FIG. Therefore, they are held in parallel at a constant pitch, and a plurality of protectors 2 are assembled along the covered wire 1 at predetermined intervals.

As shown in a partially perspective view in FIG. 4, each protector 2 is made of synthetic resin and has a base 3 into which the tip of the pressure contact portion of the contact of the connector enters. An opening 4 is formed between which a partition wall 5 is provided. Continuous arrow-shaped holding members 6 are formed symmetrically at a constant pitch at corresponding positions on both ends of the partition wall 5, that is, on both side surfaces of the protector 2.
has a protruding part 7 at the top as shown by the arrow, and this protruding part 7 widens at the base, and the distance between adjacent protruding parts 7 is equal to the width of the covered wire 1. It is slightly narrower than that. At the bottom of this protrusion 7,
The covered wire 1 is connected to the upper surface of the opening 4 of the base 3 and the protrusion 7.
An insertion space 8 is provided between the two.

FIG. 2 is an enlarged plan view for clearly showing the relationship between the protector 2 and each coated wire 1 in the protector-equipped wire of FIG. 1. FIG. As clearly shown in FIG. 2, the covered electric wires 1 are inserted into the respective insertion spaces 8 of the protector 2. That is, when the covered electric wire 1 is press-fitted from the top across the opposing holding members 6, the covered electric wire 1 is press-fitted into the insertion space 8 and held there. In this way, the protector 2 is attached to the covered wire 1 at a predetermined interval, as shown in FIG. Note that, as a matter of course, each array position of each covered electric wire 1 of each protector 2 is held in the insertion space 8 without intersecting.

When a connector is connected to the protector 2 at any position of such a wire with a protector,
The tip of the pressure welding part of each contact of the connector is inserted between the opposing holding members 6, 6, and the slit breaks the sheath of the insulated wire 1 and comes into pressure contact with the core wire of the insulated wire, and the tip of the pressure welding part of each The connection is completed by protruding into the corresponding opening 4, and in this connected state, the protector 2 can also function as a holder for a conventional connector, that is, protect the connection portion of the connector.

Since the protector 2 shown in FIG. 4 has the above-described configuration, it is not only possible to attach and hold the covered electric wire easily using a simple tool, but also to remove it or attach it to the electric wire while it is still attached. It can also be easily moved along the road. Therefore, in the electric wires with protectors shown in FIGS. 1 and 2, the first protector 2 and
The distance from the second protector 2' can be adjusted by moving either protector along the wire.
You can change it at will. Further, if there is no need to wire the connector, the protector at that portion can be removed from the wire.

In addition, according to the present invention, as shown in FIGS. 5 and 6, by attaching protectors 2 to the covered wires at regular intervals, the connector can be connected by pressure welding continuously, which shortens the connection time. and cost reduction. Moreover, this allows a continuously connected connector to be easily formed.
Furthermore, protectors attached to coated wires at regular intervals can be wound up on a take-up reel and stored in the same way as conventional flat cables, and can be stored in the required quantity when needed. It is very convenient because it is only necessary to take out the wire from the take-up reel and connect it to the connector by pressure contact. In addition, as disclosed in FIG. 6, the protector 2
Protectors 2', 2'' of almost the same shape are attached to the wire near the wire, and are provided at the same period.By this, the length of the interval between one protector 2 and the next protector 2 can be easily adjusted. For example, if you want the shortest distance, you can install the connector C integrally on the left protector 2'' and the right protector 2, and cut the wires at both ends. To do this, attach the connectors C to the left protector 2 and the right protector 2'', remove the protectors between them, and cut the wires at both ends.

Figure 7 shows the connector attached to the protector.
It is an explanatory view for manufacturing a connector with a cable. That is, it is manufactured as follows.

(1) Protector 2 is attached to covered wire 1 at relatively short intervals.
and 2' (Fig. 7A).

Moreover, the product made in this way may be wound up on a take-up reel and stored.

(2) Next, connect the connector C to the left protector 2' using a pressure welding tool (not shown) (see Fig. 7A).
and B).

(3) Next, cut the left covered wire of the left protector 2' (Fig. 7C).

(4) Finally, connect the connector C to the right protector 2 in the same way by pressure contact, and cut the wires to complete the connector with cable connected on both sides as shown in FIG. 7D.

By repeating the above steps, a connector with a cable can be completed in a short time and with simple work.

FIG. 8 shows another embodiment. That is, a second protector 2' having the same shape as the first protector 2 is provided relatively close to the left side, and a first protector 2 and a second protector 2' are similarly provided on the right side. are provided adjacent to each other, another protector P having a different size is provided between the first protector 2 and the second protector 2', and then a connector C' that fits the protector P is attached. In this case, for example, the protector P can be attached even if it is different from the pitch at which the parallel electric wires of the protector 2 are attached. Alternatively, the protector P and the protector 2 may have different sizes (FIG. 8A to C). Next, the electric wire on the left side of the protector P is cut, and the protector 2' is removed from the electric wire. Furthermore, a protector P is attached between the right protectors 2 and 2'' and the same operation is repeated.As a result, as shown in FIG. 8E, a protector P different from the protectors 2 and 2'', that is, a connector ′, C″ can be easily connected to the cable by pressure contact.

In the embodiment shown in FIG. 3, two adjacent covered wires 1 are twisted together within the predetermined interval described above to prevent twisting, tangling, etc. within the predetermined interval. In this case, the covered wires between the protectors 2 and 2' are arranged in parallel.

Effects of the invention The electric wire with a protector of the present invention has protectors that hold a large number of covered electric wires in a parallel state arranged at intervals, and furthermore, these protectors can be freely removed from the covered electric wires and can be attached along the covered electric wires. Since it is made to be movable, it exhibits the following various effects.

(1) Although the insulated wire is a single wire, it can be connected to a connector by pressure connection in the same way as a ribbon wire such as a flat cable wire, a twisted flat cable, or a ribbon cable, and after the connector is connected by pressure connection, the protector It also has the function of protecting the wiring part.

(2) By attaching a large number of covered wires to the protector in parallel, and by attaching a large number of protectors at appropriate intervals in advance, it is possible to connect connectors to the protector with a cable in a short time, and at low cost. A connector with a cable can be completed.

(3) Since the protector can be removed and attached more easily than the covered electric wire and can be moved while attached to the covered electric wire, the distance between the connectors of the connector with cable can be set arbitrarily.

(4) Like flat cable wires or ribbon wires, it can be wound and stored on a take-up reel, so it is convenient to store and can be pulled out from the take-up reel to manufacture connectors with cables whenever necessary. It is considered very convenient because it allows you to

(5) Since it is only necessary to use a protector to attach a single wire to a connector and make it into a flat cable, there is no manufacturing equipment required compared to conventional flat cables, and it is also cheaper and there is no need to worry about wire pitch accuracy. is not necessary at all and is considered highly reliable.

(6) Since protectors of different sizes can be easily attached between the parallel electric wires between the protectors, it is easy to connect different connectors. In this case, unnecessary protectors can also be easily removed.

(7) Twisting the covered wires between the protectors to prevent twisting of the wires between the protectors.
Tangle etc. can also be prevented.
