Description

A kind of double pins and three foot insert groups close two-pin plug

Technical field

The utility model is related to a kind of double pins and three foot insert groups to close two-pin plug, for only pair pins or three pins Socket takes electricity.

Background technology

When the construction of many occasions takes electricity, because socket only has two receptacle electrical connectors or three receptacle electrical connectors, three pins of carrying Plug or double pin plugs, cannot normal use.

Utility model content

In view of the above-mentioned problems, the utility model is intended to provide a kind of technical solution, show as a kind of double pins and Three pins combine two-pin plug.

The utility model is made of shell, pin, capping（Fig. 1）.

Shell 0 constructs for hollow, rectangular body, has entrance hole 12, entrance hole 13 on a face, is used for the access of power cord.Column Shape protrusion 3, columnar projections 4 and shell 0 are integrated construction, housing wall 16 of the cylindrical shell perpendicular to place.

There is silk mouth 17 in columnar projections 3（Fig. 2）, have silk mouth 18 in columnar projections 4（Fig. 3）.

Pin has 5, including live prong 5, zero line pin 6, live prong 7, zero line pin 8, earth pin 9.

Live prong 5 and live prong 7 are connected by conducting wire 15, and there is wiring hole 10 in the end of conducting wire 15；Zero line pin 6, Zero line pin 8 is connected by conducting wire 14, and there is wiring hole 11 in the end of conducting wire 14.

Live prong 5, zero line pin 6 pass through the housing wall 16 of columnar projections 3 and place face, are fixed on shell.Firewire Jack on construction between pin 5, zero line pin 6, with matching two spring hole scoket of two-phase matches.

Live prong 7, zero line pin 8, earth pin 9 pass through the housing wall 16 of columnar projections 4 and place face, are fixed on shell On body.Jack on construction between live prong 7, zero line pin 8, earth pin 9, with matching two-phase Three-hole socket Match.

There are two cappings, respectively covers 1, capping 2.Capping 1, capping 2 are all internal thread constructions.On the inner wall of capping 1, have Silk mouth 19（Fig. 4）.On the inner wall of capping 2, there is silk mouth 20（Fig. 5）.

The silk mouth 19 of capping 1 and the silk mouth 17 of columnar projections 3 match, and cover 1 silk mouth 20 and the silk mouth of columnar projections 4 18 match.

Specific implementation mode

In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, specific embodiment of the present utility model is described below.

There are two cappings, respectively covers 1, capping 2.Capping 1, capping 2 are all internal thread constructions.On the inner wall of capping 1, have Silk mouth 19.On the inner wall of capping 2, there is silk mouth 20.

The silk mouth 19 of capping 1 and the silk mouth 17 of columnar projections 3 match, and cover 1 silk mouth 20 and the silk mouth of columnar projections 4 18 match.

Under non-working condition, capping 1 is fixed in columnar projections 3, and capping 2 is fixed in columnar projections 4.It needs to take electricity When, according to socket outlet situation, determine using double pins or three pins.

When taking electricity using three pins, capping 1 to be removed, capping 2 keeps original state, in order to avoid touch pin 8, pin 9 gets an electric shock. When taking electricity using double pins, capping 2 to be removed, capping 3 keeps original state, in order to avoid touch pin 5, pin 6 gets an electric shock.

Claims (1)
