Abstract
The utility model relates to a safety fuse, wherein a binding post is connected with a lifting component through nails in the lifting component respectively. When the lifting component is lifted up, the nails are locked to press closely a wire and prevent the lifting component from detachment. A gap is arranged on the front upper portion of a base, a plurality of concave-convex lines are arranged on the interior of the head portion of a fusion loading component, which enables the fingers to extend into the fusion loading component to conveniently break off the fusion loading component when the hands are carrying out the breaking off operation on the fusion loading component, thereby can forcefully separate the contact of a blowout body and a contact and achieve labor saving without sliding. The safety fuse is suitable for power distribution equipments with a rated voltage of alternative current 220V or 380 V and a rated current which reaches up to 63 A for avoiding overloading and short circuit.
Description
The utility model relates to a kind of fusing isolator, fuses immediately by fuse-link at line short or when seriously transshipping, up to protective effect.
The screw of existing its lifters of fuse easily unclamps, thereby influences the firm of lead that binding post connects, and the easy slippage of lifters is fallen down.Because stopping of base shell makes to point when pulling fusing carrier to be difficult to put in, and is difficult for catching fusing carrier, also is difficult for firmly with strength, thereby makes operating difficulties.Because the position of pulling with finger on the fusing carrier is smooth, frictional force is little, thereby not only require great effort but also easily skid when operating, and has influenced separating rapidly or engaging of fuse-link and contact.
The purpose of this utility model is: a kind of fuse is provided, it can be pinned the screw of lifters, not slippage of lifters, guarantee wire to terminal firmly, and easy to operate, laborsaving, can guarantee the good bond of fuse-link and contact or separate.
The technical scheme that realizes the utility model purpose is as follows: a kind of fuse comprises: pedestal, fusing carrier, two contacts, two binding posts, two lifters and fuse-link, form fuse-holder by pedestal, contact and fusing carrier.Two contacts are fixedlyed connected with two binding posts respectively, and two binding posts are connected with two lifters by the screw in the lifters respectively, are pinned by pressure handle screw under the lifters.Pulling open or closing up and fuse-link and contact are engaged or separate by fusing carrier.Fore-upper part at pedestal has breach, has some concave convex textures in the inner portion of carrying melt.
Described two lifters can be to be horizontal sides above being bent into, and side is the hook-like part of vertical edges, and the horizontal sides of hook-like part is pushed down binding post.
Owing to adopt technique scheme, when the vertical edges with the hook-type lifters in the utility model fuse upwards rises, screw is compressed downwards along the binding post screw, thereby the lifters screw pins, not slippage of lifters, it is firm also to make binding post connect lead.Owing to have breach in the fore-upper part of pedestal, make when pulling fusing carrier with hand and operate, put in a part the breach that the forefinger finger tip can be opened from pedestal, make things convenient for fusing carrier to pull open, and can effectively separate contacting of fuse-link and contact.Again owing to increased concave convex texture with pointing the position pull at the fusing carrier head, make when pulling open very laborsavingly by finger, non-sliply do not wear and tear again.Therefore compared with prior art, the utility model both can pin the lifters screw, make the binding post wire-bonds firm, and not slippage of lifters can make finger manipulation convenient and strength-saving again, thereby can guarantee the good combination of fuse-link and contact or separate.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure chart of the utility model fuse
Among the figure, 3,10. binding post 4,11. contacts 5. cylinder hat fuse-links
6. fusing carrier 7. pedestals 12,13. lifters
In the embodiment of the utility model fuse shown in Figure 1, comprise two symmetries and binding post 3,10, contact 4,11 and the lifters 12,13 of putting.Contact 4,11 is fixedlyed connected with binding post 3,10 respectively, and binding post 3,10 is connected with lifters 13,12 by the screw in the lifters respectively.Be horizontal sides above lifters 12,13 is and is bent into, side is the hook-like part of vertical edges, and the horizontal sides of hook-type is pushed down binding post 3,10, and the lifters screw is pinned, and cylinder hat fuse-link 5 places between two contacts 4,11.Form fuse-holder by pedestal 7, two contacts 4,11 and fusing carrier 6, this supporter is made power supply and is not connected continually and the disjunction load circuit in circuit, use very convenient, laborsaving.This supporter and fuse-link 5 supporting uses are operated by fusing carrier 6, pull open or close up fuse-link 5 and contact 4,11 engaged or to separate.Fore-upper part at pedestal 7 has breach, has some concave convex textures in the inner portion of fusing carrier 6.
The utility model as connecting circuit, then is placed on cylinder hat fuse-link 5 in the fusing carrier 6 when operation, and fusing carrier 6 is pulled forward, promptly pulls to the right among Fig. 1, makes fusing carrier 6 rotations, and fuse-link 5 is contacted with two contacts 4,11, and circuit is connected.When wanting open-circuit line, then fusing carrier 6 is pulled backward, promptly pulled left among Fig. 1, fusing carrier 6 rotates counterclockwise, and fuse-link 5 separates with two contacts 4,11, and circuit disconnects, and fuse-link 5 is pulled out from fusing carrier 6.When line short or overload, fuse-link 5 fusing, circuit disconnects, the load device in the protection circuit.After circuit is repaired, also replaceable new fuse-link.
The utility model is applicable to that rated voltage is alternating current 220V/380V, rated current to the power distribution equipment of 63A as the usefulness of overload and short-circuit protection.
