This Europe round plug comprises housing and latch, described latch is fixed in described housing, and in described housing, extend to outside the housing, its main feature is, described housing comprises base and end cap, and described base and end cap are involutory fixing, and described base comprises two involutory assemblies, described two involutory assemblies are the half slide structure assembly with embedded chute combining form, and described latch is fixed on the described base by described half slide structure.
In this Europe round plug, described latch has the stiff end that is fixed on the described base, and the cross sectional shape of described stiff end is arc and polygonal amalgamation shape.
In this Europe round plug, described cross sectional shape is the amalgamation shape of a semicircle and a groove shaped.
In this Europe round plug, has the interference bonding structure between described latch stiff end and described base.
In this Europe round plug, described interference bonding structure is the semi-surrounding structure.
In this Europe round plug, described latch surface is covered with a nickel coating.
In this Europe round plug, this plug also comprises earthing member, and described earthing member is arranged in the described housing and is fixed on the described base.
In this Europe round plug, described earthing member has the drawer structure that engages with described base, and this drawer structure compresses by end cap and is sticked on the described base.
In this Europe round plug, an end of described earthing member has a barb, and described earthing member is connected in the sidewall of a side of described base by described barb, and the other end of described earthing member supports and is located in the sidewall of base opposite side.
In this Europe round plug, described end cap outer surface is provided with tread plate.
Adopted the Europe round plug of this utility model, because it comprises housing and latch, described housing comprises involutory fixing base and end cap, described base comprises two involutory assemblies, described two involutory assemblies are the half slide structure assembly with embedded chute combining form, described latch is fixed on the described base by described half slide structure, make that the base plastic is less, production cost is lower, the assembling of latch and base is simple simultaneously, and be difficult for taking place the phenomenon of latch loose shift, can effectively guarantee the security performance of plug.Europe of the present utility model round plug construction is simple, with low cost, and range of application is comparatively extensive.

Fig. 2 is the contour structures schematic diagram (base half slide structure open mode) after the round plug assembling of Europe of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also Figure 1 and Figure 2, be the structural representation of Europe of the present utility model round plug.
In a kind of execution mode of the present utility model, this Europe round plug comprises housing 1 and latch 2, and described latch 2 is fixed in described housing 1, and extends to outside the housing 1 in described housing 1.Described housing 1 comprises base 11 and end cap 12, and described base 11 is involutory fixing with end cap 12.Described base 11 comprises two involutory assemblies 18,19, the half slide structure assembly of described two involutory assemblies 18,19 for having embedded chute combining form, and described latch 2 is fixed on the described base 11 by described half slide structure.Described latch 2 surfaces are covered with a nickel coating.
In a kind of more preferably execution mode, described latch 2 has the stiff end 21 that is fixed on the described base 11, and the cross sectional shape of described stiff end 21 is arc and polygonal amalgamation shape.
In a kind of further preferred embodiment, the cross sectional shape of described stiff end 21 is the amalgamation shape of a semicircle and a groove shaped.
In another kind of further preferred embodiment, 11 of described latch stiff end 21 and described bases have the interference bonding structure.
Further preferred embodiment in, described interference bonding structure is the semi-surrounding structure.
A kind of preferred embodiment in, this plug also comprises earthing member 3, described earthing member 3 is arranged in the described housing 1 and is fixed on the described base 11.
In a kind of preferred execution mode, described earthing member 3 has the drawer structure that engages with described base 11, and this drawer structure compresses by end cap 12 and is sticked on the described base 11.
In the preferred execution mode of another kind, one end of described earthing member 3 has a barb 31, described earthing member 3 is connected in the sidewall of a side of described base 11 by described barb 31, and the other end of described earthing member 3 supports and is located in the sidewall of base 11 opposite sides.
Another preferred embodiment in, described end cap 12 outer surfaces are provided with tread plate 17.
In practical application of the present utility model, the base of this Europe round plug adopts half slide structure.With respect to the frame mode that two involutory backs of plastic use spiral shell to tighten, half slide structure is more reasonable.Its assembling is more convenient, need not screw-driving technology, only needs latch is positioned over predeterminated position, and by two plastics of embedded chute combination of half slide structure, then latch can be fixed on the base.Simultaneously, half slide structure can reduce plastic quantity, reduces the mould investment, reduces production costs.
