Abstract

A conjunction box is used in cooperation with a switch/socket panel. A fixing device of a connection terminal is arranged on the bottom wall of the conjunction box, and the connection terminal is fixed in the conjunction box through the fixing device. The conjunction box is used in combination with a rapid installation joint to classify and fix wires in the conjunction box in advance, thereby effectively simplifying tedious operation for installing a switch/socket.

Description

A kind of terminal box

Technical field

The utility model relates to a kind of terminal box that is exclusively used in switch/socket, belongs to the optimisation technique of switch, socket.

Background technology

Have the switch/socket terminal box with the fixing switch/socket be connected with electric wire in terminal box for containing electric wire now, mainly be divided into two kinds of bright dress and concealed installations, and substantially realize standardization, so the switch/socket of different manufacturers, brand can both support the use mutually.

When existing switch/socket is connected with the electric wire of drawing from terminal box, mainly adopt direct-connected mode, advantage is to connect simply, does not need to increase extra equipment.Usually adopt the key screw electric wire to be fixed on the binding post on switch/socket, often run into following situation in installation process: the one, if reserved wire length is shorter, mounting distance between switch/socket panel and terminal box is also less, makes the activity space deficiency of erecting tools cause installing difficulty; The 2nd, if reserved wire length is longer, although overcome above-mentioned problem, due to the limited space of terminal box, put a large amount of electric wires into limited space also more difficult; If wiring quantity is more or assign direction is more or wire diameter when larger, terminal box is more difficult having taken in just.

Therefore, need to find a kind of easy installation and connect more simple terminal box.

The utility model content

The purpose of this utility model is to provide a kind of terminal box for switch/socket that can Fast Installation.

The technical solution of the utility model is: a kind of terminal box, and for supporting the use with switch/socket panel, the terminal box diapire is provided with the fixedly fixture of the junction block 1 of Quick-mounting joint, and junction block is fixed in terminal box by fixture; Described junction block 1 is provided with binding post 2 and jack 3, and binding post 2 and jack 3 are orthogonal, and each binding post 2 is comprised of the connection jaws of one or more mutual conducting; Binding post 2 is connected by bonding conductor 4 with jack 3; Described binding post 2, jack 3 and bonding conductor 4 adopt electric conducting material to make.

Described fixture is the bayonet socket 61 be arranged on terminal box, and the deck 12 insertion bayonet sockets 61 that junction block 1 is located on junction block by handle are fixed on the terminal box diapire.

Described bayonet socket 61 runs through the diapire of terminal box, and the stop bit projection on deck 61 is stuck in outside the diapire of terminal box.

Around bayonet socket 61, be provided with holddown groove 62 in the bottom wall outer of terminal box, after junction block is fixed, the press strip 63 be complementary with holddown groove is compressed into to holddown groove, bayonet socket and deck are covered by press strip.

Described fixture is fixing indent, and fixedly indent is fixed on the terminal box inside bottom wall, and fixedly indent is provided with groove towards a side of diapire, in groove, is provided with to extend through the fixedly bayonet socket 61 of indent other end; Described bayonet socket 61 runs through the diapire of terminal box; Junction block 1 is fixed on the terminal box diapire by deck 12 is inserted to bayonet socket 61; Stop bit projection on deck 61 is positioned at groove.

Terminal box is provided with the line hole 64 supply lines turnover of five directions.

beneficial effect:

1,a kind of terminal box of fixedly Quick-mounting joint is provided, electric wire is concluded and is fixed in advance in terminal box, can effectively exempt operating process loaded down with trivial details while in the past switch/socket being installed.

2, by use terminal box of the present utility model in switch/socket, can realize Fast Installation and the quick-detachment of switch/socket.

Embodiment

As Fig. 1 to as shown in Fig. 6, a kind of terminal box, for supporting the use with switch/socket panel, the terminal box diapire is provided with the fixedly fixture of the junction block 1 of Quick-mounting joint, junction block is fixed in terminal box by fixture; Described junction block 1 is provided with binding post 2 and jack 3, and binding post 2 and jack 3 are orthogonal, and each binding post 2 is comprised of the connection jaws of one or more mutual conducting; Binding post 2 is connected by bonding conductor 4 with jack 3; Described binding post 2, jack 3 and bonding conductor 4 adopt electric conducting material to make.

Quick-mounting joint mainly comprises and connects junction block and be located at binding post and the jack on junction block.

During installation, entering wire terminations in terminal box prunes after insulator, exposed part is inserted in corresponding connection jaws by phase place, to be connected with electric wire the pressuring direction of complete junction block to the terminal box rear wall again, make the electric wire bending until junction block arrives the junction block fixed position be positioned at the terminal box inwall fixes.

Described fixture be provided with kinds of schemes, preferred version is: described fixture is the bayonet socket 61 be arranged on terminal box, junction block 1 is located at deck 12 on junction block by handle and inserts bayonet sockets 61 and be fixed on the terminal box diapire.

The advantage of the preferred version of above-mentioned fixture is that terminal box can be done thinlyyer, and the stop bit projection of deck is given prominence to outside the diapire of terminal box.

Another preferred version of described fixture is fixing indent, and fixedly indent is fixed on the terminal box inside bottom wall, and fixedly indent is provided with groove towards a side of diapire, in groove, is provided with to extend through the fixedly bayonet socket 61 of indent other end; Described bayonet socket 61 runs through the diapire of terminal box; Junction block 1 is fixed on the terminal box diapire by deck 12 is inserted to bayonet socket 61; Stop bit projection on deck 61 is positioned at groove.

The advantage of this fixture preferred version is that the back side evenness of terminal box is high.

The embodiment of terminal box as shown in Figure 1 to Figure 3 is the terminal box for single-phase socket or two-position switch.
