Abstract
The utility model relates to a circuit switch device, in particular to a novel knife switch, which comprises an insulating chassis, dual blades, a knife insulating handle, and an input junction plate, an output junction plate and a knife rest which are respectively fixed on the chassis, wherein the output junction plate is respectively arranged on the lower portions of the dual blades, and one end thereof close to the knife rest is extended upwards to form a blade holder, and the dual blades are movably connected with the upper end of the knife rest. The knife switch further comprises four connection sleeves and fastening screws, the two sides of the input junction plate and the output junction plate are respectively provided with grooves which are adapted with the length sides of the connection sleeves, and the connection sleeves are respectively sleeved in the grooves on the input junction plate and the output junction plate. The utility model improves the split type blade holder and copper junction plates in an existing knife switch into an integral structure, thereby guaranteeing the excellent contact of the junction. In addition, the connection sleeves are sleeved in the grooves on the input junction plate and the output junction plate, which avoids damages of cables which is caused by directly screwing the cable with the screws in original products on the one hand, and the connection sleeves can not slide from the junction plates, and the use is convenient.
Description
Technical field
The utility model relates to a kind of circuit switch equipment, particularly relates to a kind of novel knife switch.
Background technology
Knife switch is a kind of simple in structure, uses circuit switch equipment very widely, as the control assembly of appliance terminal, by a large amount of uses.The structure of knife switch generally is made of the base and the lug of porcelain or insulating material, and on the base of porcelain or insulating material, blade support is connected as a whole with lug lug by screw by screw.The design under the prerequisite that realizes function of this knife switch shows loaded down with trivial details slightly, and because the lug volume is bigger than normal, copper material is caused certain waste, in addition, also can increase contact resistance, cause the waste of the energy owing to the split between blade support and the lug plate connects.
The utility model content
Technical problem to be solved in the utility model is that to solve between the blade support of knife switch and the lug plate contact resistance big, the problem of the wasting of resources.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of novel knife switch, comprise insulator foot, the duplex blade, plug-in strip insulated handle and be separately fixed at input, output connection sheet and knife rest on the base, the upper end of duplex blade and knife rest flexibly connects, and the output connection sheet is separately positioned on the below of blade and an end of the close knife rest of output connection sheet extends upward the formation blade support.
As improvement of the present utility model, also comprise four sleeves and trip bolt, described sleeve is the tetragonal body that strip conductor surrounds, the upper surface of sleeve is provided with the screwed hole suitable with trip bolt; Be respectively equipped with on the two sides of described input, output connection sheet and the suitable groove of the sleeve length of side, sleeve is set in the groove on input, the output connection sheet; In the screwed hole of trip bolt spinning on sleeve.
The material of described insulator foot and plug-in strip insulated handle is a pottery.
The utility model, the blade support and the lug of split type connection in the existing knife switch are improved to an overall structure, the output connection sheet extends upward the formation blade support near an end of knife rest, because output connection sheet and blade support are structure as a whole, therefore can guarantee the good contact of wiring.In addition, input, be respectively installed with sleeve on the output connection sheet and sleeve is stuck in input, the output connection sheet upper groove, by trip bolt wiring is fixed, avoided so on the one hand that screw directly screws the damage that cable causes to cable in the original product, and sleeve can be from landing on the lug plate, and is easy to use.

Fig. 3 is an output connection chip architecture schematic diagram;
Fig. 4 is the connection diagram of blade and blade support.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises insulator foot 1, duplex blade 4, plug-in strip insulated handle 5 and be separately fixed at input wires sheet 2, output connection sheet 8 and knife rest 3 on the base 1, duplex blade 4 flexibly connects with the upper end of knife rest 3, and output connection sheet 8 is separately positioned on the below of duplex blade 4 and an end of output connection sheet 8 close knife rests 3 extends upward formation blade support 9.
Preferably, the utility model also comprises four sleeves 6 and trip bolt 7, and the tetragonal body that described sleeve 6 surrounds for strip conductor, the upper surface of sleeve 6 are provided with the screwed hole suitable with trip bolt 7; Be respectively equipped with and the suitable groove 10 of sleeve 6 length of sides on the two sides of input, output connection sheet 2,8, sleeve 6 is set in the groove 10 on input, the output connection sheet; In the screwed hole of trip bolt 7 spinnings on sleeve 6.
The material of described insulator foot 1 and plug-in strip insulated handle 5 is a pottery.
During wiring, the lead of removing insulating barrier is inserted into respectively in the bottom surface and the space between the lug plate lower surface of sleeve 6, because the upper surface butt of the bottom of trip bolt 7 and lug plate, move up along the groove on the lug plate 10 so screw trip bolt 7 drive sleeves 6, lead is pressed between the bottom surface and lug plate lower surface of sleeve 6.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection range of the present utility model.
Claims (3)
1, a kind of novel knife switch, comprise insulator foot, the duplex blade, plug-in strip insulated handle and be separately fixed at two groups of inputs, output connection sheet and knife rests on the base, described output connection sheet is separately positioned on the below of duplex blade, the upper end of described duplex blade and knife rest flexibly connects, and it is characterized in that the output connection sheet extends upward the formation blade support near an end of knife rest.
2, novel double linkage brake knife switch as claimed in claim 1 is characterized in that also comprising four sleeves and trip bolt, and described sleeve is the tetragonal body that strip conductor surrounds, and the upper surface of sleeve is provided with the screwed hole suitable with trip bolt; Be respectively equipped with on the two sides of described input, output connection sheet and the suitable groove of the sleeve length of side, sleeve is set in the groove on input, the output connection sheet; In the screwed hole of trip bolt spinning on sleeve.
