Description

a junction box

technical field

The invention relates to a junction box specially used for switches/sockets, which belongs to the optimization technology of switches and sockets.

Background technique

The existing switch/socket junction boxes for storing wires and fixing switches/sockets connected to the wires in the junction box are mainly divided into two types: surface installation and concealed installation, and have basically achieved standardization. Therefore, switches/sockets of different manufacturers and brands The sockets can all be used in conjunction with each other.

When the existing switch/socket is connected to the electric wire drawn from the junction box, the direct connection method is mainly adopted, and the advantage is that the connection is simple and no additional equipment is required. Screws are usually used to fix the wires to the terminals on the switch/socket. During the installation process, the following situations are often encountered: First, if the reserved wire length is short, the installation distance between the switch/socket panel and the junction box is also small. , the insufficient movable space of the installation tool leads to installation difficulties; second, if the length of the reserved wires is longer, although the above-mentioned problems are overcome, due to the limited space of the junction box, it is relatively difficult to put a large number of wires into the limited space. Difficult; if the number of wiring is large or the distribution direction is large or the wire diameter is large, the junction box is even more difficult to store.

Therefore, it is necessary to find a junction box that is easy to install and has simpler connections.

The fixing device is a fixed pressure groove, and the fixed pressure groove is fixed on the inner side of the bottom wall of the junction box. A groove is provided on the side of the fixed pressure groove facing the bottom wall, and a groove is provided in the groove to penetrate to the other end surface of the fixed pressure groove. bayonet 61; said bayonet 61 runs through the bottom wall of the junction box; the terminal block 1 is fixed on the bottom wall of the junction box by inserting the bayonet 61 into the bayonet; the stop protrusion on the bay is located in the groove.

The junction box is provided with wire holes 64 in five directions for power supply wires to go in and out.

Beneficial effect:

1. Provide a junction box capable of fixing quick-installation connectors. The wires are summarized and fixed in the junction box in advance, which can effectively avoid the cumbersome operation process of installing switches/sockets in the past.

2. By using the junction box of the present invention in the switch/socket, quick installation and quick disassembly of the switch/socket can be realized.

detailed description

As shown in Figures 1 to 6, a junction box is used for supporting the switch/socket panel. The bottom wall of the junction box 6 is provided with a fixing device for fixing the terminal block 1 of the quick installation joint, and the terminal block is fixed by the fixing device In the junction box; the terminal block 1 is provided with a terminal 2 and a socket 3, the terminal 2 and the socket 3 are perpendicular to each other, and each terminal 2 is composed of one or more than two interconnected connection ports ; The terminal 2 and the jack 3 are connected through the connecting conductor 4; the terminal 2, the jack 3 and the connecting conductor 4 are made of conductive materials.

The quick installation connector mainly includes a terminal block and a terminal and a socket provided on the terminal block.

When installing, cut off the insulator at the end of the wire entering the junction box, insert the exposed part into the corresponding wiring opening according to the phase, and then press the terminal seat connected with the wire to the rear wall of the junction box to bend the wire until The terminal block reaches the fixed position of the terminal block located on the inner wall of the junction box and is fixed.

There are multiple schemes for the setting of the fixing device, the preferred solution is: the fixing device is a bayonet socket 61 arranged on the junction box, and the terminal block 1 is fixed by inserting the bayonet socket located on the terminal block into the bayonet socket 61 On the bottom wall of the junction box.

The bayonet 61 runs through the bottom wall of the junction box, and the stop protrusion on the bay is stuck outside the bottom wall of the junction box.

Around the bayonet 61, a fixing groove is provided on the outside of the bottom wall of the junction box. After the terminal block is fixed, the bead matched with the fixing groove is pressed into the fixing groove, so that the bayonet and the bay are covered by the bead.

The advantage of the preferred solution of the above-mentioned fixing device is that the junction box can be made thinner, and the stop protrusion of the card seat protrudes outside the bottom wall of the junction box.
