Abstract

The utility model relates to a safe wire junction box, having a junction box and a wiring plate. The junction box is reserved with wire threading holes, and the wiring plate is arranged in the junction box. The wiring plate consists of power conductors and insulating materials. The power conductors containing a plurality of wire terminals which are respectively independent and mutually communicated are embedded in the wiring plate made by insulating material. In the utility model, the connector of each cable is fixed on the wire terminal inside the wiring plate. Wires are neatly arranged in the junction box with regular connection and without false connection, calorification and short circuit. The utility model is also characterized in safe use and convenient maintenance.

Description

Safety terminal box

Technical field

The utility model relates to a kind of circuit connection and uses accessory, specifically relates to a kind of terminal box.

Background technology

Present employed terminal box when newly constructed house or decorating house comprises the base box of switch, socket only providing a space that is used to place power lug that inside does not have any device.Its mode of connection is: with pliers with the live wire of main power source and zero line respectively with minute branch road promptly lead to another or a plurality of terminal box, the live wire and the zero line that are connected lamp and many wires of switch, socket be screwed in, be placed in the terminal box after wrapping up with insulating tape again.

The electrical equipment kind of using in current family, the office is more and more, and power load is also in continuous increase, and therefore, electric wire is just overstriking constantly thereupon also.When adopting specification is 2.5mm ²During above copper cash,, be difficult to many wires head firmly closely is screwed in together, cause the loose contact of the end of a thread easily, make conductor joint heating waste electric energy, also may occur the virtual connection sparking when serious, even damage electrical equipment because the quality of copper cash is harder.The end of a thread is too much in terminal box, and electric wire is crossed again when thick, joint takes up room greatly, has both hindered the installation of switch, socket panel, is not easy to again keep in repair.Simultaneously, after service time was long, the insulating tape of parcel power lug can aged deterioration, reduces insulation property, causes short circuit accident easily, perhaps initiation fire etc.

Summary of the invention

It is quick that the purpose of this utility model provides a kind of easy-to-connect that can make, the reliable Safety terminal box of Electrical Safety.

The utility model is made up of terminal box and terminal block, on the box body of terminal box, be reserved with through wires hole, be provided with terminal block in the terminal box, terminal block is made of electric conductor and insulating material, by several independent, the electric conductor formed of the binding post of conducting is embedded in the insulating material terminal block each other again.

Can embed one group or two groups of electric conductors on terminal block, every group of electric conductor is made up of 2～5 binding posts.Terminal block can directly be fixed on the base of terminal box, becomes one with terminal box, can also be fixedly connected on the bottom of terminal box by the terminal block of screw with activity.

Safety terminal box of the present utility model all is fixed on every wire joint on the binding post in the terminal block, and the electric wire layout is neat in the terminal box, connects well, safe in utilization, can not produce the heating power consumption phenomenon and the short circuit accident that cause because of the joint virtual connection; And whole terminal box is simple in structure, and the wiring processing ease is easy to maintenance quick.

Embodiment

Embodiment 1:

As shown in Figure 1 and Figure 2, terminal box is a rectangle box, is reserved with 8 through wires holes 5 on its bottom and four sides, is convenient to electric wire and in any direction penetrates in the terminal box.The terminal block 3 of two insulating material is separately fixed at the bottom of terminal box 2 and is close to the side, be processed as one with terminal box 2, one group of electric conductor in each embedding in each terminal block 3, and every group of electric conductor includes 3 square binding posts 4, each binding post is separate, again conducting each other.Binding post 4 on one of them terminal block is used for fixing all live wire joints, and the binding post 4 on another terminal block is used for fixing all zero line joints.

During wiring, electric wire is penetrated in the terminal box 2 from the through wires hole 5 of needs, earlier the live wire of main power line and zero line are separately fixed on any one binding post 4 on the different terminal blocks, and then other and other terminal box, lamp and switch or socket wire connecting distinguished live wire and zero line, be separately fixed on other binding post 4 of terminal block separately, after connecting all power lugs, be fixed on the screw hole 1 of terminal box 2 with the panel of screw, promptly finished wiring and installation switch, socket.

Embodiment 2:

As shown in Figure 3, Figure 4, on the bottom of a rectangular terminal box 2 and four sides, be reserved with 8 through wires holes 5, a terminal block 3 is fixedly connected on the bottom of terminal box 2 by screw 6, be embedded with two groups of parallel electric conductors at

terminal block

3,3 square binding posts 4 are arranged on every group of electric conductor, and each binding post is independently of one another, is communicated with each other again.Wherein the binding post 4 on one group of electric conductor is used for fixing all live wire joints, and the binding post 4 on another group electric conductor is used for fixing all zero line joints.

The user is what of the end of a thread number of wiring as required, change the terminal block that has different number binding posts 4 on electric conductor, use to have more flexibility, and when needs increase circuit, only need to change terminal block, need not change terminal box, keep in repair convenient, economical.

Fixing and the allocation method of the end of a thread is with embodiment 1 in the terminal box.
