Abstract

The utility model relates to a terminal box, used for fix a solid wire without fixing by a screw. The terminal box can be fixed by inserting a wire end directly. The terminal box comprises one box body in a rectangular shape roughly and a plurality of copper sheets fixedly arranged in the box body. Numbers pairs of upper open holes and lower open holes are opened at the two sides of the box body. A plurality of copper sheets are insulative to each other. An opening whose two ends bend into a barb outward faces towards the upper open holes and the lower open holes. When copper wire inserts into a lower opening, the copper wire can be clamped by the barb. When the copper wire inserts into an upper opening, the barb can be open.

Description

Terminal box

As long as the utility model relates to a kind of terminal board, especially relates to the direct terminal board that the direct insertion of the line end of single cord can be fixed.

Terminal board is common in the occasion of various distribution applications, in order to many electric wires (or cable) locking to be provided, so that energising.

Traditional terminal board as shown in Figure 1, comprises that one roughly is rectangle with the made box body 1 of insulating material, and a plurality of copper sheet 2.Copper sheet roughly is rectangle, and a screw 3 is respectively locked at two ends.Between each copper sheet 2 is mutually insulated, is separated by the dividing plate 4 of box body 1.

Please refer to Fig. 2 when using, the copper cash 6 of two electric wires (or cable), 5 inside be tie wrapped to screw 3 around, and screw 3 is locked on the copper sheet 2, copper cash 6 is well contacted with copper sheet 2 maintenances, and finishes the connection of two electric wires (or cable) 5.

Traditional terminal board must be with the de-epithelization of electric wire 5 in wiring operation, and with the copper cash 6 of inside, curved around screw 3.For thicker electric wire or cable,, it be suitable difficulty and requiring great effort around the screw, so make the efficient of wiring operation low because its copper cash is very thick and stiff usually.

The purpose of the utility model promptly is to provide a kind of terminal board structure of novelty.This terminal board is characterised in that and comprises a box body that roughly is rectangle, an and copper sheet more than being fixedly arranged in the box body, the both sides of this box body offer several on perforate and following perforate, these a plurality of copper sheet mutual insulatings, its two ends are bent into barb outwardly, and the opening of this barb can be by the embedded folder of this barb when copper cash inserts this under shed over against this upper shed and this under shed, when copper cash inserted this upper shed, this barb can open.Terminal board of the present utility model can make wiring operation finish easily and quickly.

The detailed content of the utility model is specified in down with reference to the accompanying drawings.

Fig. 1 is traditional terminal box front view.

Fig. 2 is the distribution formula of traditional terminal board.

Fig. 3 is the stereogram of the utility model.

Fig. 4 is the stereogram of copper sheet.

Fig. 5 is the cutaway view of the utility model, shows wiring method.

Label 1 expression prior art terminal board in the accompanying drawing, 2 expression prior art copper sheets, 3 expression screws, 4 expression dividing plates, 5 expression electric wires, 6 expression copper cash, 7 expression box terminals, 8 expression perforates, and 9 expression perforates, 10 expression copper sheets, 11 expression copper cash, 12 expression copper cash.

See also Fig. 3.In appearance, the box body of the terminal board 7 of the utility model roughly is rectangle, and terminal board 7 is made by megohmite insulant, for example plastic cement.The both sides of terminal board 7 are provided with several not shown to perforate 8 and 9(opposite side).The copper cash external diameter of the slightly larger in diameter of perforate 8 and perforate 9 in electric wire (or cable) inserts for copper cash.

In the inside of terminal board 7, be provided with several copper sheets 10, to match with perforate 8 and perforate 9.Copper sheet 10 is that the copper sheet by the tool favorable elasticity is bent into shape shown in Figure 4, its left-right symmetric, and two ends are bent into barb outwardly.The minimum range of its barb is little than the external diameter of copper cash, so that the copper cash embedding is sandwiched in wherein.

See also Fig. 5, copper sheet 10 is to be fixedly arranged within the terminal board 7, and mutually insulated between each copper sheet 10.The opening of the barb of copper sheet 10 is over against perforate 8 and 9 up and down.

When using terminal board 7, and will desire earlier that skin divests outside the wire connecting, expose the copper cash 11 of inside as terminal box.Then copper cash 11 is inserted by the perforate 9 of terminal board 7, copper cash 11 promptly enters the barb of copper sheet 10, and is copper sheet 10 embedded folders.Heavy coated with last action, after all desire wire connecting insertions, promptly finish wiring operation.Owing to copper cash must not gone for a stroll and locks, so the speed of distribution can greatly improve.

When distribution need be removed, as long as with another root copper cash 12, as shown in Figure 6, insert perforate 8 in the direction of arrow A, the barb of copper sheet 10 is partly opened, copper cash 11 can be extracted out in the direction of arrow B, and then extraction copper cash 12 gets final product.

Claims

1, a kind of " terminal board ", it is characterized in that comprising a box body that roughly is rectangle, an and copper sheet more than being fixedly arranged in the box body, the both sides of this box body offer several on perforate and following perforate, these a plurality of copper sheet mutual insulatings, its two ends are bent into barb outwardly, the opening of this barb perforate and this time perforate on this, can be when copper cash inserts this under shed by the embedded folder of this barb, when copper cash inserted this upper shed, this barb can open.
