Description

[Detailed Description of the Invention] The present invention relates to a branch line connector for insulated wires.

A branch line connector has been proposed that electrically connects a main line and a branch line using a wire restraint fitting with a blade without destroying the insulation.

This type of connector has a pair of insulating frames that approach each other by tightening bolts, and a wire clamp that has multiple blades that are attached to one or both of the insulating frames and bite into the insulating coating layer of the main line and branch line. It consists of metal fittings.

The main line and branch line are inserted into both frames without peeling off the insulation coating layer, the frame is tightened with bolts, and the blade of the wire holding fitting is brought into contact with the conductor of the main line and branch line, thereby connecting the main line and branch line with electricity. connected.

However, in a branch line connector with this structure, if it becomes necessary to replace the branch line, the bolts are loosened, the frame is disassembled, the main line and the branch line are removed from the connector, and the main line and the new branch line to be replaced are connected again. Since the main line and branch line must be electrically connected in the same way as described above by inserting it between the retaining metal fittings, it is necessary to disassemble the connector each time the branch line is replaced, which makes replacing the branch line troublesome. Ta.

An object of the present invention is to provide a branch line connector that can easily connect a branch line and a main line without disassembling the connector.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a branch line connector 10 according to the present invention.

This branch line connector 10 includes a case 12, a pair of wire holding fittings 14 and 14' installed in the case 12, and a terminal 16 disposed inside the case 12 and integrally formed with the wire holding fitting 14. and a bolt 18 passing through the center of the case 12.

The case 12 consists of a pair of box-shaped case halves 20.degree. 20, and is assembled by fitting one case half 20 into the other case half 20.

As shown in FIG. 1, the case half parts 20, 20 are integrally formed with semi-cylindrical main line penetration parts 20a, 20a and semi-cylindrical branch line penetration parts 20b.

A bolt 18 for tightening these case halves 20 passes through a circular hole 20C in the case half 20, and a nut 21 is screwed into the bolt 18.

A pair of wire holding fittings 14, 14'U each with a plurality of blades 2
2 and 22', and holes 14a and 14a' for the bolt 18 to pass through are provided in the center.

These wire holding fittings 14 and 14' are fixedly attached to the inner wall surface of the case half 20.degree. 20 with a plurality of blades 22 and 22' facing each other.

A bolt 18 is screwed into the hole 14a'.

The female terminal 16 is integrally formed with the wire holding fitting 14 and has a tulip-like elastic structure fitted into a cylindrical hole 16a provided in the center thereof coaxially aligned with the branch wire penetration part 20b of the case half 20. It consists of a spring member 24.

The branch line connector of the present invention is characterized in that the branch line can be detachably attached after being connected to the main line side.

That is, the main line 26 made of an insulated wire is inserted into the main line penetrating portion 20a of one case half 20.

20a, and the other case half 20 is inserted into this case half 20.

Next, the bolt 18 is passed through the hole 20C1 of one case half 20, the holes 14a and 14a' of the wire holding fitting 14°14', and the bolt 18 is passed through the hole 20c of the other case half 20, and then the nut 21 is inserted.
are screwed together and the case halves 20, 20 are tightened together.

In this way, as shown in FIG.
2' bites into the insulating coating layer 26a of the main wire 26 and the conductor 2
The female terminal 16, which is in contact with the wire holding member 6b and is therefore integrally formed with the wire holding fitting 14, is in electrical contact with the main wire 26 when the connector 10 is attached to the main wire 26.

To connect the branch wire 2B made of an insulated wire to this female terminal 16, attach a male terminal 30 made of a compression strip IJ to the end of the conductor, and connect this male terminal 30 to the case half 2B.
It is fitted into the elastic spring member 24 of the female terminal 16 through the branch line penetration portions 0 and 20.

Therefore, when replacing a branch line, pull the branch line 28 to pull out the male terminal 30 from the female terminal 16, and insert the male terminal fixed to the new branch line to be replaced into the elastic spring member 24 of the @terminal 16. Bye.

Note that reference numeral 32 is an insulating cap that is fitted into the hole 20c of the case half 20 to cover the head of the bolt 18.

Another embodiment is shown in FIG.
It consists of a leaf spring 36 which is disposed in a space 34 surrounded by 4.14' and fixed to one of the wire holding fittings 14.

Therefore, the male terminal 30 is connected to the main line 26 via the leaf spring 36.

In addition, in the above two implementations, the male terminal 30 is used, or if the conductor of the branch line is made of a single wire, the conductor may be inserted directly into the female terminal without using the male terminal. .

According to the present invention, as described above, the main wire is connected to a wire holding fitting having a blade that bites into the insulating coating layer, and the branch wire is connected to the wire holding fitting, so that the conductor of the branch line can be elastically attached and detached. Since the branch line is connected to the elastic female terminal to be engaged, it is easy to attach and detach the branch line, and the branch line can be easily replaced without disassembling the branch line connector.
