Abstract
The utility model discloses a dropping fuse which comprises an insulation frame. The top of the insulation frame is fixed on and connected with an upper connection plate by two fastening bolts. The upper connection plate is connected with a rain shield. The bottom of the insulation frame is connected with the upper connection plate and a lower connection plate and the frame. The upper connection plate and the lower connection plate are respectively connected with an upper contact and a lower contact which are arranged on two ends of a fusion tube by a upper touch plate and a lower touch plate. The utility model respectively uses two fastening bolts fixing and arranging the upper connection plate and the lower connection plate and the frame on the insulation frame. The utility model not only is reliably connected but also effectively prevents the loosening and torsion situations among the components, so the utility model can be widely used in the production of dropping fuse.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage electric device, particularly a kind of outdoor high-voltage drop type fuse.
Background technology
Fuse is a kind of protection equipment that the protection electric equipment is avoided short circuit, overload infringement.Fuse includes insulating support, the insulating support upper end is connected with upper wiring board, upper wiring board is connected with rain cover, described insulating support lower end is connected with following terminal block and support, upper and lower terminal block is in contact with one another by the small contact on the upper and lower contact at upper and lower contact and fusion tube two ends respectively, its operation principle is that the melt in the fusion tube of fuse is melted when line short or overload, thus interrupting short circuit.
At present, the upper and lower terminal block of the outdoor high-voltage drop type fuse that uses in the electric power system all has only a screw rod to connect with insulating support, be subjected to the influence of outdoor environment, be easy to become flexible, reverse after operation a period of time, also the punch forming of support employing brass sheet, and the cost of raw material is than higher, intensity is also not so good, and there is tangible weak spot in support intensity, is easy to flexural deformation, and these problems are easy to cause operating trouble in service; All have a small contact in upper and lower contact end in addition, so promptly increased the conduction link, influenced the electric conductivity of product, also increased difficulty of processing and manufacturing cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of fuse switch reliable, that conduct electricity very well that connects.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fuse switch, it comprises insulating support, the insulating support upper end is fixedly connected with upper wiring board by two fastening bolts, upper wiring board is connected with rain cover, the lower end of described insulating support is connected with following terminal block and support by two fastening bolts, and upper and lower terminal block directly contacts with the upper and lower contact at fusion tube two ends by upper and lower contact respectively;
As improvement of the technical scheme, described support and rain cover adopt the corrosion resistant plate punch forming;
As further improvement in the technical proposal, described support is in the form of slot and extend to junction with insulating support.
The beneficial effects of the utility model are: this product adopts respectively by two fastening bolts and will go up, following terminal block and support are fixedly mounted on the insulating support, this design not only connects reliable, and effectively prevented between accessory loosening, situation about reversing occurs, in addition, support that this product uses and rain cover adopt corrosion resistant plate or general steel plate punch forming, both increased mechanical strength, reduced manufacturing cost again, outward appearance is more beautiful, simultaneously, last contact and following contact all are not provided with small contact, directly directly contact with following contact respectively with the upper contact head at fusion tube two ends, improve the electric conductivity of product, reduced difficulty of processing and manufacturing cost simultaneously, made this product can be widely used in the making of fuse switch.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of fuse switch, it comprises insulating support 1, insulating support 1 upper end is fixedly connected with upper wiring board 3 by two fastening bolts 2, upper wiring board 3 is connected with rain cover 4, the lower end of described insulating support 1 is connected with following terminal block 5 and support 6 by two fastening bolts 2, and upper and lower terminal block 3,5 directly contacts with the upper and lower contact 11,12 at fusion tube 10 two ends by upper and lower contact 8,9 respectively.
This product adopts respectively by two fastening bolts 2 and will go up, following terminal block 3,5 and support 6 be fixedly mounted on the insulating support 1, this design not only connects reliable, and effectively prevented between accessory loosening, situation about reversing occurs, in addition, support 6 that this product uses and rain cover 4 adopt corrosion resistant plate or general steel plate punch forming, both increased mechanical strength, reduced manufacturing cost again, outward appearance is more beautiful, and in design support 6 is designed to the groove shape and extends to junction with insulating support 1, the weak spot that former support exists has effectively been eliminated in this design, strengthened the support strength of product, simultaneously, last contact 8 and following contact 9 all are not provided with small contact, directly directly contact with following contact 12 with the upper contact head 11 at fusion tube two ends respectively, have improved the electric conductivity of product, reduce difficulty of processing and manufacturing cost simultaneously, made this product can be widely used in the making of fuse switch.
