Abstract
The utility model relates to a novel drop type fuse. A problem that when an elastic piece of an existing drop type fuse is used for a long time, the elasticity is decreased, the connection with a fusion tube is poor, a circuit is disconnected in the condition of no fault, and the normal working of the circuit is affected is solved. The novel drop type fuse is characterized in that an upper connection plate is provided with an elastic electrical connection plate, the fusion tube is provided with an electricity input clamping plate, the elastic electrical connection plate is provided with a U type groove, the electricity input clamping plate is provided with a clamping part which is matched with the groove, the elastic electrical connection plate is provided with an elastic reinforcing plate which is provided with a spring, one end of the spring is connected with the elastic reinforcing plate, and the other end of the spring is connected with the upper connection plate. The novel drop type fuse is provided with the U type groove, the service life of the elastic piece is greatly prolonged, and the stability of a mechanism is improved.
Description
Technical field
The utility model relates to a kind of fuse, is specifically related to a kind of novel fuse switch.
Background technology
Fuse switch is that fuse is passed on the contact that fusing carrier is fixed on two ends.When line short or overload, fuse in the fuse forms electric arc, and at the drop-down long arc of the effect of elastic body, make inner aerogenesis medium resolve into gas, in the fusing carrier pipe, form very high pressure, the electric arc that forms is blown out, thus interrupting short circuit, and fusing carrier falls and forms an isolation fracture.Many employing flexure strips contact between the junction block fusion tube on the existing fuse, flexure strip is after long-term the use, and elastic force descends, and can't connect fusion tube preferably, and open circuit under trouble-free feelings money influences the circuit operate as normal.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel fuse switch, mainly solve the flexure strip of existing fuse switch after long-term the use, elastic force descends, can't connect fusion tube preferably, open circuit under trouble-free situation influences the problem of circuit operate as normal.
The technical scheme that the utility model adopts is: a kind of novel fuse switch, comprise insulation column, fusion tube, described insulation column is provided with upper wiring board, described upper wiring board is provided with elasticity and connects electroplax, described fusion tube is provided with into electric clamping plate, described elasticity connects electroplax and is provided with U-shaped groove, describedly advance electric clamping plate and be provided with the Access Division adaptive with groove, described elasticity connects electroplax and is provided with the elastic reinforcement plate, described elastic reinforcement plate is provided with spring, described spring one end is connected with the elastic reinforcement plate, and an end is connected with upper wiring board.
Described insulation column is provided with down terminal block, and described fusion tube is provided with the crimping plate, and described terminal block down contacts with the crimping plate.
Described Access Division forms by advancing the bending of electric clamping plate.
The beneficial effects of the utility model are: be provided with U-shaped groove, greatly prolonged the useful life of flexure strip, improved mechanism stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged drawing at the utility model A place.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of novel fuse switch, comprise insulation column 1, fusion tube 2, described insulation column 1 is provided with upper wiring board 3, described upper wiring board 3 is provided with elasticity and connects electroplax 4, described fusion tube 2 is provided with into electric clamping plate 5, described elasticity connects electroplax 4 and is provided with U-shaped groove 6, describedly advance electric clamping plate 5 and be provided with the Access Division 7 adaptive with groove 6, described elasticity connects electroplax 4 and is provided with elastic reinforcement plate 8, described elastic reinforcement plate 8 is provided with spring 9, and described spring 9 one ends are connected with elastic reinforcement plate 8, and an end is connected with upper wiring board 3.
Described insulation column 1 is provided with down terminal block 10, and described fusion tube 2 is provided with crimping plate 11, and described terminal block 10 down contacts with crimping plate 11.
Described Access Division 7 forms by advancing electric clamping plate 5 bendings.
The concrete use of the utility model is as follows: during use, because the Access Division of advancing on the electric clamping plate 57 embeds grooves 6, fusion tube 2 is connected firmly and indefatigability with upper wiring board 3.When groove 6 is clamp-oned in Access Division 7, make spring 9 and 8 distortion of elastic reinforcement plate, 8 pairs of grooves 6 of spring 9 and elastic reinforcement plate apply one perpendicular to the power on groove 6 tops, make fusion tube 2 more firm with being connected of upper wiring board 3.
The beneficial effect of utility model is: be provided with U-shaped groove, greatly prolonged the useful life of flexure strip, improved mechanism stability.
