Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-core structure in which two or three core wires, each of which is insulated and coated from a single conducting wire generally used as a power line, are arranged in parallel, and the outer periphery thereof is covered with a sheath. Alternatively, for a three-core VVF cable, another VVF cable such as branching a power system in another direction or branching a wiring for a switch, for example, at the time of wiring such a VVF cable or at an existing wiring already wired. In order to obtain a branch line by connecting the existing lines, the current lines of the existing line and the branch line must be connected with the same polarity without error, and a simple operation can be performed even if the VVF cable of the existing line is a live line that is energized. The present invention relates to a connector that enables branch connection.

[0002]

2. Description of the Related Art Conventionally, such a two-core or three-core VVF is used.
When connecting a separate 2-core or 3-core VVF cable to a cable to obtain a branch line, it is generally necessary to distinguish between the positive and negative sides of the core when energizing various devices.
In a VF cable, the coating of a plurality of conducting wires is colored according to a color that is easy to identify. On the other hand, a display mark indicating the position of the core wire on at least the positive electrode side or the negative electrode side at the same time as the distinction by color of each core wire is provided on the outer surface of the cable.
There is a VF cable.

[0003] In the case of such a branch line taking out work, if the main line is a live line, after turning off the power to eliminate the danger, the VVF cable on the main line and the VV cable on the branch side are usually turned off.
Expose the energizing wires of the respective core wires of the F cable, insert the energizing wires of the same polarity of both VVF cables together and insert them into the metal sleeve inside the closed end insulating cap, and apply pressure from above using a pressurizing tool. The pressurized metal sleeve is deformed under pressure and connected by crimping. However, in such a means, when the main line is a live line, it is necessary to stop the power supply before the branching work because of the necessity of electric shock prevention, and during that time a power outage state is inevitable, and Since the work is very troublesome, the construction time is long and the work efficiency is low.

[0004] In order to solve such a problem, the applicant has invented and proposed a connector shown in FIG. 11 which takes the case of a two-core VVF cable as an example. That is, the parts common to the embodiment will be described using the same reference numerals. The insulation sheath 31 and the insulation inner skin 32 of each of the main line side VVF cable 3 and the branch side VVF cable 3 'are cut to connect the two cables. A metal contact 1 in which two notches 11 to be contacted with the conducting wires 33 of the same polarity to be formed are formed at a predetermined interval and the top surface 1a is covered with an insulating resin plate 15; The main body 2 is made of a resin. The main body 2 is made of a synthetic resin. The main body 2 is made up of half body parts 2 a and 2 b connected by a folding part 24 and a connecting part 25.
a and a cover body 26 connected to the
In a, grooves 21 and 22 corresponding to half of the wiring holes through which the main line side VVF cable 3 and the branch side VVF cable 3 'are respectively inserted.
2 are arranged in parallel, and in order to insert two of the contacts 1 one by one at predetermined positions, the contacts 1 are mutually shifted in the width direction of the cable by a distance d between the positive and negative energizing wires 33. Inserted holes 23 are formed at two places, and grooves 21 ′ and 22 ′ corresponding to half of the wiring holes are formed in the main body 2 b corresponding to the grooves 21 and 22. ing.

[0005] The work procedure is as follows: the main body structure 2a and the main body structure 2b of the main body 2 are bent and united, and the groove 21 and the groove 2 are formed.
1 'and the main line side VVF cable 3
After inserting the ends of the branch-side VVF cable 3 'into the wiring holes formed by the grooves 22 and 22', respectively,
The contact 1 is inserted from one of the insertion holes 23 and pressed, so that the positive-side conducting wire 33 of the main-line-side VVF cable 3 is cut between the one cut-out portion 11 of the contact 1 and the other cut-out portion. 11, the positive conducting wire 33 of the branch-side VVF cable 3 ′ is cut into and electrically connected to both conducting wires. Next, another contact 1 is inserted from the other insertion hole 23 and pressed, and the main line V
The negative conducting wire 33 of the VF cable 3 is electrically connected to the negative conducting wire 33 of the branch VVF cable 3 '. Thereafter, the cover 26 is covered with the main body 2a to close the insertion hole 23.

[0006]

In the connector proposed by the present inventor, the pressing of the contact 1 can be easily performed by a one-handed operation using a crimping tool. Since the top surface 1a of the contact 1 is covered with the insulating resin plate 15 and the contact 1 has a function of cutting and peeling off the insulating coating of the cable, the live part is not exposed to the human body during the work. It has the feature that even if the main line side VVF cable is energized, even non-experts can work safely and without erroneous recognition of polarity, but it is one of the main parts The contact 1 is formed by press-molding a metal plate, plated for rust prevention, and further has an insulating resin plate 15 separately formed by synthetic resin molding or the like fixed to the top surface 1a. Manufacturing man-hours Ku, was and is a problem to be solved by the manufacturer price because the wood material and anti-rust plating also is necessary to say that the higher the order of the insulating material.

Accordingly, the present invention is based on the connector proposed by the present inventor and proposes an improved contact for a branch connector which is simple in structure and inexpensive, thereby covering the VVF cable. It is an object of the present invention to provide an inexpensive connector with a simple structure, which can safely and quickly perform a branching operation of an electric wire even when power is supplied without completely removing the connector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In implementing a connector having such a configuration, any applicable VVF cable may be used. First, the polarity of each energized line of a main line and a branch line is determined. From the standpoint of discriminating without error, V
As the VF cable, the polarity of the core wire can be identified as shown in the drawings of the embodiment and the conventional example, or the display mark 34 indicating the position of the conducting wire on the positive electrode side or the negative electrode side.
It is desirable to use a VVF cable provided with a cable outer surface.

The contact 1 is made of a material having higher hardness and higher conductivity than soft copper used for the conducting wire 33 of the VVF cable 3, such as a hard copper alloy plate having high hardness. preferable. A material metal plate having an insulating coating film 14 on both surfaces or at least one surface of such a metal plate has a cross-sectional shape as viewed from the side surface of two parallel pieces 1c.
A substantially inverted U-shape having a VVF cable 3,
By cutting the insulating inner skin 3 'of the cable 3', two cut portions 11 and 11 are formed at a predetermined interval D so as to come into contact with the conducting wire 33 to be connected to the cable, and the insulating sheath 31 of the cable is cut. Molding is performed so that the cutting blades 13 that enter between the adjacent insulating inner skins 32 and separate the right and left sides are formed near the cut portions 11, 11. In this case, the insulating coating film 14 is provided on at least the outer surface of the contact 1, that is, the top surface 1a and the boundary side surface 1b. By forming the above-mentioned insulating coating film 14 by, for example, baking, a coating film having high mechanical strength that can withstand press molding can be obtained.

In this way, the outer surface of the contact 1 is kept electrically insulative, and the contact 1 is electrically connected to the crimping tool A when it is press-fitted into the main body 2 to make contact with the energizing wire 33 at two places. The branch connection can be performed even when the main line is energized. Further, when the insulating coating film 14 is applied to both surfaces of the material metal plate, plating for rust prevention becomes unnecessary, and the insulating resin plate 15 in the conventional example and the mounting process thereof are also unnecessary. In addition to this, it is possible to significantly contribute to cost reduction as compared with the conventional example.

In order to maintain the contact 1 in an insulated state, in addition to the above-described means, after forming a metal plate on which the insulating coating film 14 is not formed into a predetermined shape, at least the top surface 1a when the contact 1 is mounted. In addition, a coating may be applied to the boundary side surface 1b of the cutting blade 13 located between the adjacent insulating inner skins 32, 32 in the cable to form the insulating coating film 14. In this case, if the metal plate as the raw material is a material having high corrosion resistance, rust-proof plating can be omitted. In the case where the insulating coating film 14 is formed by painting, the contact 1 may be formed by simply processing a single flat plate so that the side surface has a predetermined shape.

The interval (D) between the two cut portions 11 of the contact 1 is set equal to the mutual interval (= D) between the arranged VVF cables 3 and the connected VVF cables 3 '. Further, the notch width of the notch 11 is determined by pressing the contact 1 against the VVF cable 3 and cooperating with the cutting blade 13 to cut off the insulating sheath 31 and the insulating inner skin 32 of both cables, and oppose the notch 11. Since the energization is performed with the energizing line 33 on the inner side surface, the width is preferably slightly smaller than the thickness of the energizing line 33. By doing so, it is possible to firmly press and hold from both sides while plastically deforming the conducting wire 33 by the pressing force during this conducting operation. The thickness of the contact 1 and the width of the cutout 11 are related to the amount of plastic deformation of the conducting wire 33 received by the pressing force. It is preferable to set the area so as to have the above area. Also, notch 1
1 is to incline with respect to the insertion direction, so that the positive and negative conducting wires in one cable are separated from each other when the conducting wire is pressed and clamped, to prevent accidents such as short circuit. Can be.

In addition, a cutting blade 13 is formed on the end surface near the cut portion 11 of the contact 1 by cutting the insulating sheath 31 and entering between the insulating inner cores 32 of the adjacent core wires to separate them. Crimping work becomes easy. In this case, since the insulating coating film 14 is applied to the outer surface of the cutting blade 13, that is, the boundary side surface 1 b located between the insulating inner skins 32, 32, the positive and negative conducting wires are erroneously contacted via the contact 1. And has the effect of favorably maintaining the insulation state between the positive and negative core wires.

The connector body 2 is composed of two body structures 2a and 2b of substantially the same shape and a half-shape, and a cover body 26. The shape of the body connected by the folding part 24 and the connecting part 25 is nylon, polyethylene, or the like. The whole is integrally molded with a resin material such as polypropylene. The grooves 21 and 22 formed in the main body components 2a and 2b are arranged side by side with each other and are arranged in parallel with a distance D between the centers of the grooves. 3 is formed as a wiring hole passing through the main body 2, and the VV of the branch line is formed.
Since the groove 22 through which the F cable 3 ′ is inserted starts from the connection portion of the main line of the VVF cable 3, it becomes a dead end wiring hole inside the main body 2. In this case, a groove 2 that is a dead end
The shield wall 28 may be provided at the end of the second line to prevent rainwater from entering the end surface of the VVF cable 3 'of the branch line. In the case of bidirectional branching, the VVF cable 3 'of the branch line passes through the main body 2 like the VVF cable 3 of the main line, so that the shielding wall 28 can be easily cut off in order to serve also in this case. Structure or
A shielding wall 28 is provided near the ends of the grooves 21, 22, 21 'and 22'.
For example, a structure may be adopted in which the shielding wall 28 is detachable, for example, by forming a shielding wall groove 29 for fitting therein, and fitting a shielding wall 28 made of a transparent body into the shielding wall groove 29.
Further, by making the shielding wall 28 of such a separate member a transparent body, the polarity can be confirmed by looking at the cut surface of the VVF cable 3 ′.

In another embodiment, the groove 22 is formed in the groove 2.
The two cables may be formed so as to overlap with each other, and the two cables may be overlapped and arranged in parallel. In this case, the groove 22 overlaps with the groove 21 to be a common groove, and the appearance is such that either groove is deepened so as to simply accommodate two cables. The contact 1 is connected between the energizing line on the right side of the VVF cable 3 and the energizing line on the right side of the VVF cable 3 '(that is, the same polarity), and between the energizing line on the left side of the VVF cable 3 and V
The contact holes 23 of the contacts 1 are provided at the positions on the side surfaces in the longitudinal direction of the respective cables so that the left conducting wires of the VF cables 3 'are brought into contact with each other. Of course, in the case of this other embodiment, it is needless to say that the polarity indication marks 34 of the main line VVF cable 3 and the branch line VVF cable 3 'must be arranged so as to overlap in the same direction.

As the wiring work, the groove 2 of the main body structure 2b is used.
1 and a VVF cable 3 'in a groove 22, and a cut end face thereof is abutted against a shielding wall 28 and housed therein, and the main body 2a is placed on the main body 2b. When the contact 1 is inserted from the insertion hole 23 and pressed by the crimping tool A, the cut portion 11 cooperates with the cutting blade 13 to cover the insulating sheath 3 of the cable.
1 and the insulation endothelium 32 or the insulation endothelium 32 are cut off to supplement the energizing wire 33, and the energizing wire 33 is firmly pressed from both sides while being plastically deformed by pressing force. After the contact 1 is inserted, the cover 26 is placed from behind the main body 2a to prevent rainwater or the like from entering through the insertion hole 23.

The contact state between the conducting wire 33 and the contact 1 depends on the plate thickness of the contact 1 and the cut 1
Since the interval of 1 is set so that the contact area thereof becomes larger than the cross-sectional area of the conducting wire 33 due to the plastic deformation of the conducting wire 33, the contact resistance is extremely low, and there is no problem such as heat generation. .

The surface of the contact 1 has an insulating coating 14
Is formed, and is completely insulated from the crimping tool A. Therefore, even if the main line is in a live state, no accident such as a short circuit or an electric shock occurs, and the main line and the branch line can be operated in one operation. Is completed completely and without any error such as polarity.

In the case where the surfaces 1c, 1c are present at a small interval, the work is facilitated by cutting the insulating outer cover 31 in the length direction. Further, the cut portion 11 is formed to be slightly inclined so as to widen the interval between the two core wires of the VVF cable. Increasing the distance between the two core wires facilitates the longitudinal cutting of the insulating sheath 31 by the cutting blade 13 as described above, and at the same time, prevents the cutting blade 13 from making erroneous contact with the other adjacent core wire in parallel. .

(Not shown). This modification is similar to the insertion hole 2 of the main body 2 as described later.
By making the shape 3 the same as that of the top surface 1a, it has a feature that the direction can be given when the contact 1 is inserted.

In the main body 2, the main body components 2a and 2b, the cover body 26, the folded portion 24, and the connecting portion 25 are manufactured by integral molding of a synthetic resin. The raw material synthetic resin uses polypropylene, but nylon, polyethylene,
Polycarbonate or the like may be used. In the main body 2 of the first embodiment, a shielding wall groove 29 for fitting the shielding wall 28 is formed near the ends of the grooves 21, 22, 21 ', 22'.
The structure is such that a shielding wall 28 made of a transparent material is fitted into the shielding wall groove 29. By doing so, the grooves 21, 22, 21 ′, 2 of the main cable and the branch cable are formed.
It is possible to freely deal with any of the positional relationship with respect to 2 ', bidirectional branch, and unidirectional branch. Further, during and after the work, the connection polarity of the conducting wire can be confirmed by looking at the cut surface of the VVF cable 3 '.

In the first embodiment, the connection operation will be described with reference to FIGS. 1 and 5 and thereafter. The connection operation between the main line VVF cable 3 and the branch line VVF cable 3 'is as follows.
First, the main line VVF cable 3 is inserted into the groove 21 'of the main body 2b, and the branch side VVF cable 3' is inserted into the groove 22 '.

The contact 1 is inserted from the insertion hole 23 (FIG. 5) and pressed by the crimping tool A (FIG. 6). In cooperation therewith, the insulating sheath 31 and the insulating inner skin 32 of the cable are cut to supplement the conducting wire 33, and the conducting wire 33 is firmly pressed and clamped from both sides while being plastically deformed by the pressing force. After the contact 1 is inserted, the cover body 26 is put over the back of the main body component 2a, and the hook 27a is hooked and fixed on the hook ring 27b to prevent rainwater or the like from entering through the insertion hole 23. FIG. 7 shows a cross section in this connection state. FIG. 8 shows an appearance state after the work is completed.

FIG. 9 shows a second embodiment, in which a three-core VFF cable is branched using a contact 1 having an insulating coating film 14 formed by painting on the surface of the main part shown in FIG. This is an example. In the figure, although hidden inside and cannot be seen, grooves 21 and 22 wider than those of the first embodiment are arranged in the main body components 2a and 2b in parallel with the three-core VVF cable. Insert holes 23,...
