Abstract

The utility model relates to a knife and socket integrated switch. Two screws and screw caps for fixing fuses on the lower part of a porcelain base of a knife switch are fixed with two spring clamps of a socket, and the distance between two spring clamps of the socket coincides with the distance between standard single-phase double-pole plug pieces. The upper side of a lower cover of the knife switch is provided with two socket holes corresponding to clamp openings of the spring clamps of the socket. The knife and socket integrated switch has the advantages of low cost, safety, and convenient use; the knife and socket integrated switch can be smoothly provided with the socket without making a big change on the knife switch in the prior art.

Description

Plug-in strip socket integral switch

The utility model relates to a kind of low-voltage power device, particularly a kind of plug-in strip socket integral switch that is used for civilian low pressure.

Along with society constantly develops, people's living standard is also more and more higher, and various household electrical appliance are leapt up in a large number into family.As air-conditioning, electric rice cooker, electric frying pan, warmer, electric furnace ... or the like the bigger electrical equipment of power consumption, all need an electrical equipment one knife switch, use just convenient and safe.And China's existing HK series knife switch (being existing small-sized single-phase bipolar power knife switch) function singleness, supply socket all must be installed in addition, connects with power line, could use.Not only wasted but also hidden adventurous accident potential.

The purpose of this utility model is to provide a kind of installing to save easily the plug-in strip socket integral switch that is easy to use safe to the public.

The technical scheme that the utility model adopted is:

Existing knife switch (as HK series) and receptacle combinations are integral.

Concrete technical measures are:

The hand-tight nut 4 of existing knife switch lower cover is screwed off, open knife switch lower cover 3, will be with regard to two of knife switch porcelain base 6 the belows fixedly screw and the nuts of fuse, two socket spring folders 8 are fixed up, the distance of two socket spring folders is determined according to standard single-phase bipolar plug blades distance, processes on the knife switch lower cover and two corresponding two socket apertures of socket spring folder dop.

If single-phase bipolar band ground protection socket knife switch and three-phase three pole socket knife switches; socket spring clamping is decided method such as above-mentioned; a single-phase bipolar band ground earth electrode of protection just increasing and grounding receptacle spring folder, the distance of three socket spring folder socket spring folders is determined according to the plug blades distance of standard three-terminal polarized plus plug.On the knife switch lower cover, process and three corresponding three socket apertures of socket spring folder dop.

If three-phase three utmost point band ground protection socket knife switch, socket spring clamping is decided method such as above-mentioned, just increases an earth electrode and grounding receptacle spring folder, and the distance of four socket spring folders is determined according to the plug blades distance of standard four utmost point plugs.On the knife switch lower cover, process and four corresponding four socket apertures of socket spring folder dop.

Advantage of the present utility model is;

1, with low cost, benefit is obvious.Can not add cartridge socket smoothly with moving big " operation " to existing knife switch, socket spring folder can be bought and be used to make the socket spring folder stock that usefulness is pulled in wiring on the market.The socket aperture that covers under the knife switch, as long as on its mould, increase by two, or three, or four die sheets get final product.

2, safe and reliable, easy to use.High pressure resistant and the high temperature of knife switch porcelain base, appropriate as long as fuse is selected, it is reliable, easy to use to be perfectly safe.

Embodiment

The hand-tight nut of existing knife switch lower cover is screwed off, open the lower cover of knife switch, to socket spring clamping be got up surely with regard to the screw and the nut of the fixedly fuse below the knife switch porcelain base, the distance of two socket spring folders is determined according to standard single-phase bipolar plug blades distance.On the knife switch lower cover, process and two corresponding two socket apertures of socket spring folder dop.

Can not add cartridge socket smoothly with moving big " operation " to existing knife switch, socket spring folder can be bought and be used to make socket spring that wiring pulls usefulness on the market and press from both sides from stock and get final product, or strikes out material piece with copper sheet on mould, and then drawing.The socket aperture that covers under the knife switch, as long as on its mould, increase by two, or three, or four die sheets get final product.

Claims

1, a kind of plug-in strip socket integral switch is characterized in that: below knife switch porcelain base the two fixedly screw and the nuts of fuse, be fixed with two socket springs folders, and the distance of two socket spring folders and standard single-phase bipolar plug blades are apart from consistent; Two and the corresponding socket aperture of socket spring folder dop are arranged on the lower cover of knife switch.

2, plug-in strip socket integral switch according to claim 1, it is characterized in that: single-phase bipolar band ground protection socket knife switch and three-phase three pole socket knife switches, three socket spring clampings fix on three fixedly on the screw of fuse, and one of single-phase bipolar band ground protection switch is earth electrode and grounding receptacle spring folder; The distance of three socket spring folder socket spring folders is determined according to the plug blades distance of standard three-terminal polarized plus plug; On the lower cover of knife switch, have and three corresponding three socket apertures of socket spring folder dop.

3, plug-in strip socket integral switch according to claim 1, it is characterized in that: three-phase three utmost point band ground protection socket knife switch, socket spring clamping fixes on four fixedly on the screw of fuse, one of them is earth electrode and grounding receptacle spring folder, and the distance of four socket spring folders is determined according to the plug blades distance of standard four utmost point plugs; On the knife switch lower cover, process and four corresponding four socket apertures of socket spring folder dop.
