Abstract

The utility model discloses a multipurpose bipolar plug, which comprises an insulation rubber body and inserting pins, wherein the inserting pins are fixed onto the insulation rubber body through rotatable insulation gear parts, each insulation gear part is provided with a square hole matched with the corresponding inserting pin, the insulation rubber body is formed by fixing an upper shell and a lower shell by means of screwing, one end of each inserting pin extending into the insulation rubber body is provided with a binding screw hole, a binding screw for fixing a wire is arranged on the corresponding binding screw hole, and the wire penetrates through a wiring channel of the insulation rubber body to enter the insulation rubber body and then to be connected with the binding screw holes and is fastened in the binding screw holes through the binding screws. The multipurpose bipolar plug has the advantages that the additionally arranged plastic insulation gear parts widen the use range of the bipolar plug, so that the bipolar plug can be used with not only a single-phase 10A bipolar socket but also a single-phase 10A tripolar socket, the use amount of wall sockets can be decreased, and further the use ratio of existing resources is increased.

Description

A kind of two utmost point multipurpose plugs

Technical field

The utility model relates to a kind of electrical accessorie, relates to a kind of two utmost point multipurpose plugs more specifically.

Background technology

The combination of plug and socket is the most conventional connector of electric equipment and power connection.Existing market common plug be divided into two-wire plug and three-terminal polarized plus plug; Wherein the latch of two-wire plug is fixed in the insulation colloid; Its position is can't moving or rotate of fixing; Can only with the specific supporting use of two pole sockets, the jack on these two specific pole sockets also must be suitable with latch position and size on the two-wire plug.Therefore people in daily life, the electrical equipment that occurs having two-wire plug through regular meeting is too much, two utmost point jacks that connect power supply very little, the vacant situation of three utmost point jacks on the contrary.

The utility model content

The purpose of the utility model is to provide a kind of two utmost point multipurpose plugs, has solved the problem that existing plug only is applicable to two utmost point jacks that are complementary with it.

For addressing the above problem, the technical scheme that the utility model is taked is:

A kind of two-wire plug comprises insulation colloid and latch, and described latch is fixed on the insulation colloid through rotating insulation gear.

For making the utility model play better technique effect:

Technical scheme further is to have the square hole suitable with latch on the above-mentioned insulation gear.

Technical scheme further is that above-mentioned insulation colloid is to be spirally connected by upper shell and lower house fixedly to form; The end that described latch stretches in the insulation colloid is provided with the wiring screw; The wiring screw is provided with the terminal screw that is used for fastening electric wire; The wire casing that electric wire passes the insulation colloid gets in the insulation colloid and links to each other with the wiring screw, and is fastened in the wiring screw through terminal screw.

Technical scheme further is in the above-mentioned insulation colloid tension disc to be installed further.

Adopt the beneficial effect that technique scheme produced to be: in the utility model with setting up plastic gear spare respectively on two latches; Through the mutual interlock between plastic gear spare; Rotate latch and change its angle; Realized that promptly two-wire plug can insert two utmost point jacks and can insert the needed angle of three utmost point jacks again, realized the functional diversities of two-wire plug, improved the utilance of plate jack.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail: like Fig. 1 and shown in Figure 4: a kind of two utmost point multipurpose plugs; Comprise insulation colloid and latch 3; Latch 3 is fixed on the location notch 11 of insulation colloid through rotating insulation gear member 4; Insulation has with latch 3 on the gear member 4 and penetrates suitable square hole 13, and screw 10 backs that the insulation colloid penetrates upper shell screw 16 and lower house by screw 6 are tightened fixedly with nut 14 and formed.The end that latch 3 puts in the insulation colloid is provided with wiring screw 12; Wiring screw 12 is provided with the terminal screw 5 that is used for fastening electric wire; The wire casing 15 that electric wire passes the insulation colloid gets in the insulation colloids and links to each other with wiring screw 12, and is fastened in the wiring screw through terminal screw 5.In the insulation colloid tension disc 7 is installed also further, tension disc 7 is fixed on the screw 9 of lower house through screw 8, is used for fixing electric wire.

When socket is only reserved two utmost point jacks, the corresponding installation of the square end surface of plastic gear spare 4, the position when inserting two utmost point jacks corresponding (combination assumption diagram is with reference to figure 2) with latch; When socket was only reserved three utmost point jacks, the mutual interlock of the gear face of plastic gear spare 4 was installed, and rotated latch 3 to the angle (combination assumption diagram is with reference to figure 3) that is fit to insert three utmost point jacks.This novel two-wire plug of having realized can insert the demand that two utmost point jacks can insert three utmost point jacks again, has realized that the variation of two-wire plug function changes, and has improved the utilance of plate jack.

Claims
