Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a single (not a fine twisted wire) energizing wire generally used as a power line, which is insulated and coated, and is arranged in parallel. For a VVF cable covered with an insulation coating, when wiring such a VVF cable or when connecting another VVF cable to an already-wired existing wiring to obtain a branch line, a current-carrying line and a branch line on the positive electrode side of the existing wiring are used. The present invention relates to a connector suitable for connecting and branching a current-carrying line on the positive electrode side without error.

[0002]

2. Description of the Related Art It is often necessary to connect such a VVF cable to another VVF cable to obtain a branch line. In this case,
In some cases, it is necessary to distinguish the positive side and the negative side of the current-carrying line when power is supplied to various devices, and therefore, the color of the interior coating of the VVF cable is generally a different color that can be easily identified.
For example, the color of the interior coating of VVF cables is often two colors, white and black. When a branch line is taken out from the main line, it is common practice to connect the white-covered conductive line of the main line to the white-covered conductive line of the branch line, and similarly connect the black-covered conductive lines to each other.

[0003] In such a branch line removal work, when the main line is a branch line, the power is turned off to eliminate the danger, and generally, as shown in FIG. First, the VVF cable 3 on the main line side is cut at a required location, the respective outer coverings 31 are removed, the covering wires on the positive and negative sides are respectively taken out, and the inner coverings 32 are further removed and passed. The electric wire 33 is exposed.
Similarly, for the VVF cable 3 'on the branch side, after removing the outer coating 31 and the inner coating 32 on the positive electrode side and the negative electrode side to expose the energizing wire 33, the VVF cable 3' is branched from the positive-side energizing wire 33a of the main line. The positive electrode side conducting wire 33a of the wire is put together,
The metal sleeve 5 is inserted into the metal sleeve 5 housed inside the closed end insulating cap 51, pressurized from above with a pressing tool to deform the metal sleeve 5 under pressure, and pressure-bonded to each other. The energizing wires were connected.

As another means, a VVF cable is taken out of the energizing line as described above, these are divided into a positive electrode side and a negative electrode side, respectively, and the energizing lines are twisted and connected by a tool. Alternatively, a method has also been used in which a copper sleeve is put on these members and pressure-bonded and connected, and then an insulating tape is wound around each surface to cover them.

[0005]

In these conventional means, after the outer skin of the VVF cable is peeled off for a certain length to take out the endothelium, the inner length is removed to expose the energizing wires, and then the energizing wires are connected to each other. Since the electrical connection is made, the connection between the current-carrying wires on the positive electrode side and the current-carrying wire on the negative electrode side can be made arbitrarily without requiring special consideration. However, if the main line that is the branch line is a branch line, the power must be turned off before the branching work because of the necessity of electric shock prevention. Since the work is very troublesome, the construction time is long and the work efficiency is poor.

[0006] Therefore, as a means for eliminating such danger and improving the work efficiency, in the branch connection work of a VVF cable, it is omitted without performing a complicated work of removing an insulating coating. In order to be able to safely and quickly perform the branch connection work of the electric wires without danger of an electric shock accident, the electric wires are branched without stripping the inner and outer coatings of the VVF cable at all. The present applicant has previously proposed a connector capable of performing the work (see Japanese Patent Application No. 8-78).

However, when this prior art connector is used, it is difficult in this prior art to recognize the above-described positive-side conductive lines and between the negative-side conductive lines and securely connect them. The present invention further improved this, and as described above,
It is a connector that can safely and quickly branch wires without stripping the inner and outer coatings of the VVF cable. It is an object of the present invention to provide a connector that can be recognized and securely connected.

[0008]

A connector used for connecting and branching a two-core VVF cable 3 ', comprising a contact 1 made of a metal plate having a high electrical conductivity and a main body 2 made of a synthetic resin having a high insulating property. Both VVF

The main body 2 is formed with two parallel grooves 2 formed at a predetermined interval E through which the two VVF cables 3 and 3 ′ are inserted.
The two main body components 2a and 2b are provided with the main body components 2a and 2b, which are provided with the insertion holes 23 of the contacts 1 and 22 and are foldably connected to each other by a folding part 24 on one side, and the two main body components 2a. , 2b are extended outwardly from the other folds 25, 25 and hook portions 27, 27
And two cover bodies 26, 26 that are foldably connected to the main body constituting bodies 2a, 2b, and the two grooves 21, 22 are provided in the two VVF cables 3, 3 ′.
Are formed to be substantially the same width as the width w on the narrow side of the main body 2a, 2b, and the facing width of the grooves 21, 21, 22, 22 in the folded posture between the two main body components 2a, 2b is equal to the VVF.
The two grooves 21 and 22 are formed so as to have substantially the same width as the width W of the cables 3 and 3 ′ on the side of the conducting wires.
And the two notches 11, 1 of the contact 1

Is provided with a through-hole 2h for confirming the cable inner wall, which penetrates in the thickness direction separately from the contact insertion hole 23.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In implementing a connector having such a configuration, a part of a bottom portion of a groove 21 provided with a through hole 2h for confirming the inside of a cable and a portion adjacent to the through hole 2h is partially formed. A portion 34 from which a part of the outer skin has been cut off to the extent that the color of the endothelium can be confirmed is applied to the built-up portion 29, and the connector and the The present invention can be embodied as a configuration in which the relative movement with the cable 3 on the branch line side is prevented and at the same time the color of the endothelium can be confirmed from the outside.

The two grooves 21 and 22 are formed so as to penetrate the entire width of the main body components 2a and 2b, respectively, and the VVF cable 3 'on the branch side is inserted into the insertion groove 22.
Of the cable 3 'protruding from both sides may be used as branch lines to obtain two branch lines, and the groove 22 through which the VVF cable 3' on the branch side is inserted may be formed. It is assumed that a shielding wall 28 is formed on one end side, and a cut end of the VVF cable 3 ′ on the branch side is applied to the shielding wall 28 and protrudes only in one direction to obtain only one branch line. It can also be implemented as one.

The contact 1 is preferably made of a material which is higher in hardness and superior in conductivity than soft copper used for the conducting wire of the VVF cable 3, such as a hard copper alloy plate having a high hardness. . The contact 1 is not limited to one flat plate, but may be used for connection of one line, for example, connection of a line on the positive electrode side. The shape is not limited to a flat plate, but may be a U-shape or a U-shape in a side view.
In short, it suffices that two notches 11, 11 that are in electrical contact with the conducting wire 33 are formed at two places on the flat plate portion at an interval D corresponding to the interval between the two VVF cables. .

The cut interval (slit interval) of the cut portion 11 is determined by pressing the contact 1 against the VVF cable 3 to cut the outer coating (outer skin) 31 and the inner coating (endothelium) 32 of the cable and cut. Since the energization line 33 is energized on the inner surface facing the portion 11, the width is preferably slightly smaller than the thickness of the energization line 33. In this manner, it is preferable that the energizing wire 33 be firmly pressed and clamped from both sides while plastically deforming the energizing wire 33 by the pressing force during the energizing operation.

Further, the thickness (plate thickness) of the contact 1 and the interval between the cuts 11 are set such that the contact area is equal to or larger than the cross-sectional area of the conducting wire 33 in the state of contact with the conducting wire 33. It is good to keep. Needless to say, when two or more contacts 1 are used to connect one of the wires, the sum of the contact areas of all the used sheets should be equal to or larger than the cross-sectional area of the conducting wire 33. By doing so, the electrical resistance of the contact portion between the contact 1 and the conducting wire 33 can be kept low, accidents such as heat generation can be prevented, and a connector that can be used safely can be obtained. it can.
