Abstract
The utility model discloses a wiring reinforcement plate used in a drop type fuse, which comprises a fixing mounting part, an outgoing wire connecting part and a stopping part. The fixing mounting part extends horizontally, the outgoing wire connecting part is perpendicular to the fixing mounting part, the tail end of the outgoing wire connecting part slantingly extends downwards to form the stopping part, and a boss is transversally arranged at the tail end of the stopping part. The lateral surface of the wiring reinforcement plate is fundamentally C-shaped, and the wiring reinforcement plate is in a reverse T shape after being spread. The wiring reinforcement plate has excellent elasticity, and does not block a fuse tube due to the fact that the stopping range is increased.
Description
Technical field
The utility model belongs to the fuse technical field, is specifically related to a kind of wiring stiffener that is used for fuse switch.
Background technology
Fuse is a kind of protection equipment that the protection electric equipment was avoided the short circuit infringement.Its operation principle is when line short or overload, melt in the fuse fusing carrier is dissolved formation electric arc, and at the drop-down long arc of the effect of elastic body, high arc temperature makes the inner aerogenesis medium of fusing carrier resolve into gas simultaneously, in the fusing carrier pipe, set up very high pressure, free metal gas bleed pipe is made arc extinction outward, thereby cut-off short circuit current, fusing carrier falls under the effect of deadweight simultaneously, forms a visible isolation fracture.The history in existing more than 50 year of the development of China's fuse switch, in early days based on imitative Soviet Union product, the mid-1970s has improved many products from grinding, because of product material and design level are limit, manufacture level improves little, the later stage eighties increases along with introducing with exchange of technology, and product has had tremendous development, has possessed world standard substantially.Because the short circuit interruption ability of fuse improves constantly and good and economic, now accepted and be extensive use of by vast power consumer, nearly 2,000,000 of annual demand.
Fuse switch is one of the most frequently used electrical device of distribution system, also is the power product of distribution system use amount maximum.But because its unit value is lower, structure is simple relatively, all is some small-sized manufacturing firm processings basically in China, and product exists shortcomings such as break performance instability, through-current capability is low, the life-span is short, and is not solved well recent decades.
At present, no matter be domestic or external product, used wiring stiffener since shape too simplify, narrow and small, stuck cartridge fuse phenomenon takes place easily.
The utility model content
The purpose of this utility model provides a kind of wiring stiffener that is used for fuse switch that has elasticity and can not block cartridge fuse.
The technical scheme that realizes the utility model purpose is: a kind of wiring stiffener that is used for fuse switch comprises fixed installation portion that horizontal direction extends, the outlet connecting portion vertical with fixed installation portion and from the stop part of described outlet connecting portion end diagonally extending formation downwards; The end of described stop part is provided with boss along horizontal direction; The side basic configuration of described wiring stiffener is a C shape, described wiring rib being shaped as after flattening
Shape.
Described fixed installation portion is provided with the fixed installation hole, and described outlet connecting portion is provided with connecting hole.
The utlity model has positive effect: (1) the utility model is owing to comprise from the stop part of described outlet connecting portion end diagonally extending formation downwards; The end of described stop part is provided with boss along horizontal direction; The side basic configuration of described wiring stiffener is a C shape, described wiring rib being shaped as after flattening
Shape; The wiring stiffener of this shape has good elasticity, also permanent deformation can not take place under violent bump, in addition, owing to have the boss of extending transversely, has increased and stops scope, effectively prevents to block the generation of cartridge fuse phenomenon.
Description of drawings
Fig. 1 is a kind of perspective view of the present utility model;
Fig. 2 is the end view of wiring stiffener shown in Figure 1.
Be labeled as shown in the accompanying drawing: fixed installation portion 1, fixed installation hole 11, connecting hole 21, outlet connecting portion 2, stop part 3, boss 4.
Embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of embodiment of the present utility model, and wherein Fig. 1 is a kind of perspective view of the present utility model; Fig. 2 is the end view of wiring stiffener shown in Figure 1.
Present embodiment is a kind of wiring stiffener that is used for fuse switch, comprises fixed installation portion 1 that horizontal direction extends, the outlet connecting portion 2 vertical with fixed installation portion 1 and from the stop part 3 of described outlet connecting portion 2 ends diagonally extending formation downwards; The end of described stop part 3 is provided with boss 4 along horizontal direction; The side basic configuration of described wiring stiffener is a C shape, described wiring rib being shaped as after flattening
Shape.
Described fixed installation portion 1 is provided with fixed installation hole 11, and described outlet connecting portion 2 is provided with connecting hole 21.
Owing to comprise from the stop part 3 of described outlet connecting portion 2 ends diagonally extending formation downwards; The end of described stop part 3 is provided with boss 4 along horizontal direction; The side basic configuration of described wiring stiffener is a C shape, described wiring rib being shaped as after flattening
Shape; The wiring stiffener of this shape has good elasticity, also permanent deformation can not take place under violent bump, in addition, owing to have the boss of extending transversely, has increased and stops scope, effectively prevents to block the generation of cartridge fuse phenomenon.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
Claims (2)
