Abstract
The utility model aims at providing a novel power switch which mainly has the technical scheme that a cuboid ceramic base is provided with a guillotine device; two pieces of inverted hooks are arranged at the tail end under the cuboid ceramic base; and the inverted hooks are rotatably connected with waist holes at the tail parts of two pieces of elastic sheet iron at the bottom of a plastic cover in a buckling way. The novel power switch is simple in structure and easy in manufacturing and processing; the material adopted by the power switch resists high temperature and high pressure, and has low manufacturing cost and long service life; and a circuit is convenient and fast for refitting and disconnecting, and the novel power switch has wide market prospect.
Description
Affiliated technical field:
The present invention relates to a kind of electrical equipment, instrument mains switch, especially a kind of novel power supply switch.
Technical background:
At present, common on the market mains switch, top chopper device pedestal is set to face directly, the metallic conductor that chopper exposes when closed is more, and fail safe is not very high, and the below lid adopts pottery more, and be fixed on the cuboid base with screw, need turn on screw during the wiring dismounting, and be that the monoblock lid removes, place cumbersome.
Summary of the invention:
The utility model is in order to solve the problem of above-mentioned existence, aim to provide a kind of novel power supply switch, the problems referred to above are properly settled, the purpose of this utility model is achieved in that a kind of novel power supply switch, mainly be by a chopper device is set above the cuboid ceramic base, the below end is provided with two barbs, with cover below the waist hole revotating card of two elasticity iron plate afterbodys of vinyl cover bottom link and connect.Described its base of chopper device is set to the above arc-shaped curved surface of 2 groups or 2 groups and fixes with the cuboid ceramic base.
Described cuboid ceramic base inside is provided with 3 groups or 3 groups of above wiring grooves, is provided with two groups of interval troughs at least, and its inside has the above rectangle counterbore of 5mm at least.
Described elasticity iron plate is set to
Shape is fixed in the vinyl cover bottom.
Described vinyl cover afterbody is provided with two rectangular through-hole.
The utility model is simple in structure understands that processing and fabricating is easy, and the material high temperature high voltage resistant of employing is cheap, and long service life is rebuild, convenient and swift when disconnecting circuit, and market prospects are wide.
Description of drawings:
Fig. 1 is the utility model embodiment stereogram;
Fig. 2 is that the utility model embodiment takes schematic diagram apart.
Number in the figure explanation: cuboid ceramic base 1, barb 2, vinyl cover 3, elasticity iron plate 4, waist hole 5, arc-shaped curved surface 6, wiring groove 7, interval trough 8, rectangle counterbore 9, rectangular through-hole 10.
Embodiment:
Below in conjunction with drawings and Examples structure of the present invention and principle are further described:
A kind of novel power supply switch mainly is by a chopper device is set above the cuboid ceramic base 1, and the below end is provided with two barbs 2, with cover below waist hole 5 revotating cards of two elasticity iron plate 4 afterbodys of vinyl cover 3 bottoms link and connect.Described its base of chopper device is set to 2 groups or 2 groups of above arc-shaped curved surfaces 6 and fixing with 1 of cuboid ceramic bottom; Described cuboid ceramic base inside is provided with 3 groups or 3 groups of above wiring grooves 7, is provided with two groups of interval troughs 8 at least, and its inside has the above rectangle counterbore 9 of 5mm at least; Described elasticity iron plate 4 is set to
Shape is fixed in vinyl cover 3 bottoms; Described vinyl cover 3 afterbodys are provided with two rectangular through-hole 10.
When circuit is overhauled use, turn off the chopper switch, slightly firmly can open vinyl cover 3, rotation is come, the waist hole 5 of elasticity iron plate 4 afterbodys on the vinyl cover 3 is tangled by the terminal barb that is provided with in cuboid ceramic base 1 below, next can carry out service work; After maintenance is finished, vinyl cover 3 rotation is got on, the rectangle counterbore 9 by cuboid ceramic base 1 inside with vinyl cover 3 on elasticity iron plate 4 snap fit, chopper device again closes.Convenient to operation, simultaneously, the chopper device pedestal is set to arc-shaped curved surface 6, makes the metallic conductor that exposes that chopper can lack to the greatest extent when rotated, has strengthened the coefficient of safety of work greatly.
