It is preferred that conduction is inserted as, the two poles of the earth are inserted or three extremely insert, suitable for existing frequently-used socket.

It is preferred that conductive one kind being inserted as during flat slotting, round slotting or side inserts.

It is preferred that the material of insulation sleeve and the material of hand-held insulating end are inconsistent, insulation sleeve and hand-held insulating end Can be separately manufactured, flexibility is good, while replacement insulation sleeve is also allowed for after insulation sleeve damage.

It is preferred that the material of insulation sleeve is consistent with the material of hand-held insulating end, it is easy to produce.

It is preferred that the material of the insulation sleeve is to possess insulation, high temperature resistant, waterproof, high tenacity, the work of high rigidity Journey plastics.

It is preferred that the material of insulation sleeve is one kind in PI, PEI, PES, PEEK, common engineering is selected to mould Material, is more convenient for obtaining, can reduce cost to a certain extent.

It is preferred that insulation sleeve is unrestricted in the shape that conduction is plugged.

It is preferred that conductive insert is integrally formed with insulation sleeve, it is easy to make.

Inserted and insulation sleeve adds shaping it is preferred that conductive, for example insulation sleeve is sleeved on conduction and plugs, it is this install or Person's assembling form, flexibility is good, and the requirement to manufacture is relatively low.

Plug it is preferred that insulation sleeve is sleeved on conduction and be embedded in hand-held insulating end.

The beneficial effects of the utility model are：

1st, insulation sleeve can form a layer insulating between pin and human body, effectively prevent plug in swapping process due to Human contact's pin exposed part and get an electric shock, also reduce pin and light a fire with aquatic products the harm of lace；

2nd, compact overall structure, rationally distributed, can be compatible with the progress of existing socket well.
