Description

[Detailed Description of the Invention] The present invention relates to an improvement of a branch connection device for indoor wiring electric wires and cables.

Conventionally, as a branch connection device for indoor wiring wires and cables, so-called quick-connect terminals (width locking terminals) are used to complete electrical and mechanical connection by inserting the conductor of the wiring cable to save labor in wiring work. Devices that connect and branch multiple cables are widely used.

However, in this case, the number of lines inserted is generally 2 to 4, and the wiring inside the device is 1 input line and 3 branch lines.
It is limited to a few patterns that are rarely used, such as one input line and a line that is branched from human power and one side is the load and the other side is the switch.

Therefore, its use is limited in recent indoor wiring, which is complex and has a large number of circuits.

/ On the other hand, these days, there are many lights in one room, and there are many cases where it is necessary to branch and connect the electric wires and cables of several circuits such as switch circuits and outlets for various electric appliances. When making a device, there are many types of wiring patterns, and there is no degree of freedom at all.
Furthermore, when the number of wires is small, there is a disadvantage that the number of times is left over, making it uneconomical.

In order to eliminate these drawbacks, a box with a large number of quick-connect terminal attachment parts is prepared, a plurality of quick-connect terminals for the required circuit are incorporated in this box, and these quick-connect terminals are connected. Although the problem can be solved, the following problem occurs in this case.

In other words, 1. Because the quick-connect terminals are installed around the box wall and the wiring for this connection is concentrated in the center of the box,
Wiring between terminals intersects in a narrow space, leading to the risk of incorrect wiring, resulting in poor workability.

2. It was difficult to systematically arrange each quick-connect terminal, and there was a risk of incorrect connection.

etc., and a solution is desired in this regard.

In order to meet the above-mentioned needs, the present invention enables quick-connection terminals to be arbitrarily incorporated and wired into a device having a large number of terminal attachment parts, and the connection of a large number of quick-connection terminals can be performed reliably with good workability on a wide flat area. The present invention also provides a branch connection device in which quick connection terminals can be systematically arranged on a flat surface so as to commonly face each other.

In other words, its gist is that it has a table surface and a wide back surface opposite to the table surface, and has a large number of conductor insertion holes that are coaxially drilled from the periphery of the table surface toward the back surface, and on the back surface. an insulating board having a large number of terminal accommodating parts formed therein and communicating with each conductor insertion hole; an insulating cover fitted on the back surface of the board; The device is housed in a plurality of terminal units and has a ready-to-connect terminal facing the conductor insertion hole and a connection terminal led out on the back surface, and is configured to connect a plurality of the terminal units. The branch connection device is characterized in that each connection terminal is internally connected in a wiring space set between the back surface and the insulating cover.

As explained below with reference to the drawings, 1 is a table surface 1a.
It is an insulating substrate having a wide back surface 1b on the opposite side, and a large number of conductor insertion holes 2, 2.2, etc. are coaxially formed around the central part of the table surface 1a. The conductor insertion hole 2 and the terminal storage portion 3 are provided with a large number of terminal storage portions 3, 3. are communicated within the substrate 1.

Reference numeral 4 denotes a hat-shaped insulating cover that is fitted over the back surface 1b, and has a flat portion 4a that is equivalent to the table surface 1a.

Reference numeral 5 designates a terminal unit to be attached to each terminal storage part 3, including a quick-connect terminal 5a stored in the terminal storage part 3 and arranged facing at the bottom opening of the conductor insertion hole 2, and a terminal unit 5a located above the back surface 1b from this storage part 3. and a connection terminal 5b led out to the
It is mounted on the back surface 1b with a presser plate 6 fixed with screws or the like.

Reference numeral 7 designates a wiring wire, which is connected to the wiring terminal 5b and is internally wired using the wide internal space 8 between the back surface 1b and the insulating cover 4.

In the device of the present invention, the number of terminal units 5 may correspond to all of a large number of terminal storage sections 3, 3, 3, etc., and the number of terminal units 5 may correspond to all of the terminal storage sections 3, 3, 3, . In some cases, the selection is made depending on the branching mode.

When incorporating a plurality of terminal units selected according to the request, the insulating cover 4 is removed and attached to the required terminal storage part 3, 3.3, etc., and fixed with the holding plate 6. Each connection terminal 5b led out around the wide surface on the rear surface 1b is connected with an electric wire 7, and an insulating cover 4 is fitted over the connection terminal 5b to complete the desired branch connection device.

The specific structure of the quick-connect terminal 5a is not particularly limited, but one made of a plate spring is suitable, and a disconnection device may be provided if necessary.

Further, the shape of the connection terminal 5b is usually selected to be suitable for spot welding with soldering, and if necessary, it may be of a ready-to-connect structure.

The device assembled in this way is transported to the wiring site,
A conductor 10 obtained by stripping the end of the cable 9 is inserted into a predetermined conductor insertion hole 2 from the front of the table surface 1a, and then inserted into a quick-connect terminal 5a to perform predetermined wiring.

A large number of cables 9 are used as required to configure one line for the power supply and multiple lines for outlets, electric lights, etc., but according to the present invention, conductor insertion holes are formed around the flat surface of the table surface 1a. 2, 2.2, . . . are set, each insertion position of the conductor can be easily selected.

In particular, by taking advantage of the feature that conductor connection work can be completed on the table surface 1a, a label with a circuit diagram or a connection instruction diagram is attached to the center of the table surface 1a, and branch connections are made by checking each conductor insertion hole and the label. This makes it possible to do this and is very effective in eliminating incorrect wiring.

In addition, according to the present invention, the side surface of the insulating substrate 1 may be other than the circular shape shown in the embodiment diagram, or may be a rectangular shape, or may be any other shape as long as it provides a wide table surface and a wide back surface. Can be changed.

As explained above, according to the branch connection device of the present invention, when a large number of quick-connect terminals are installed, each quick-connect terminal can be connected on a wide flat surface, so wiring can be made in a wide space with plenty of room for mistakes. Wiring etc. can be cleaned up and workability can be improved, and each quick-connect terminal can be arranged coaxially and systematically on the flat part of the table surface, making it easier for workers to connect multiple cables. The effects are enormous, such as being able to reliably and easily achieve the following.
