Abstract
The utility model relates to a slide contact loading switch. The utility model is composed of a base (1), a wiring sheet (2), a wire pressing sheet (3), a touch knife (6), a contact (8), a fuse wire wiring sheet (7), screws, a gasket, etc. The utility model is characterized in that an arc separation groove and an arc separation wall (4) are arranged on the base (1); the contact (8) which is provided with two parallel elastic metal sheets is arranged on the base (1); a slide groove is arranged on the fuse wire wiring sheet; the touch knife (6) slides along the slide groove which is arranged on the fuse wire wiring sheet (7) so that the touch knife is inserted into or withdrawn from a position between the two elastic metal sheets of the contact (8), and thereby, a circuit is switched on or off. Because the utility model uses slide wire contact, the utility model has the advantages of flexible and stable contact, copper material saving, reduced cost, good arc separation, safety, etc.
Description
The utility model relates to the electric switch technical field, particularly the load electric switch of low pressure sliding contact.
At present, the on-load switch of low voltage control circuit use all gets HK2 or HK4, HK8 type knife switch usually.This switch is a contact in the moment of closing a floodgate, or the contact of very short line, so the temporary impact electric current is big, plays spark sometimes, damages electric equipment easily.And this knife switch consumption copper material is many, the cost height.
The purpose of this utility model provides a kind of flexible operation, and arc is effective, and the instantaneous of connection is low pressure (380 volts of following voltage) the loaded line sliding contact formula on-load switch of steady line contact.
The utility model is design like this: it is by low-voltage insulation electroceramics base, lug plate, pressure-ray film, contact, contact knife, steel ball, handle, packing ring, Bakelite Cover, fuse lug plate, composition such as insulating packing, screw, wherein, insulation electroceramics base is provided with the hole and the arc separating wall (groove) of parts such as terminal screw that three-phase power line inlet wire and outlet are installed respectively, contact knife, contact, fuse lug plate, hold-down screw; Conductive contact has two good conductive metal sheets of parallel to each other and close elasticity; The fuse lug plate is fixed on the base, which is provided with chute; The conduction contact knife that can slide along the chute of fuse lug plate has in the middle of two parallel metal sheets that can inject contact and the blade of good line contact is arranged with it; Handle is installed on the contact knife.
The utlity model has following premium properties: 1, control crank can promote contact knife and steadily and neatly moves around along the chute on the fuse lug plate, thereby realize contact knife and contact stably moment line contact with service time interior face contact and circuit be switched on or switched off, avoid producing instantaneous high heavy current surge and producing electric arc with the connecting and disconnecting of electric line, spark even damage power consumption equipment instrument because of on-load switch.2, this on-load switch is being saved respectively more than copper material 60% or 40% on the knife switch basis between the HK2 of existing use HK4 and HK8 type.3, arc is effective.
Introduce structure of the present utility model in detail below in conjunction with embodiment.
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment, and Fig. 2 is the vertical view of Fig. 1; Among the figure: 1, base, 2, lug plate, 3, pressure-ray film, 4, arc separating wall, 5, handle, 6, contact knife, 7, fuse lug plate, 8, contact, 9, steel ball, L1～L7 hold-down screw.
Embodiment:
Present embodiment as shown in Figure 1 and Figure 2, the line situation of each phase of three characteristics of the middle term power line is identical, so only one being that example describes in detail mutually wherein. Lug plate 2 and 2 pressure-ray films 3 are fixed on the electroceramics base 1 by hold-down screw L2 and terminal screw L1, L3, contact 8 is by hold-down screw L6, pressure-ray film, terminal screw L7, be fixed on the base 1, fuse lug plate 7 is fixed on the base 1 by hold-down screw 5, and pressure-ray film is fixed on the fuse lug plate 7 by terminal screw L4, contact knife 6 is installed in the chute of fuse lug plate by steel ball 9, and handle is contained on the contact knife.Between terminal screw 3 and screw 4, set up fuse (peace when using) by the user, between terminal screw 1 and pressure-ray film 3, connect electric power incoming line, between terminal screw 7 and pressure-ray film 3, connect output line, just can energized power in the middle of two sheet metals of control crank 5 with contact knife 6 propelling contacts 8.When stopping using, control crank 5 withdraws from contact knife 6 in the middle of two sheet metals of contact 8, and circuit just is disconnected.
