Abstract
The utility model discloses a clip for fuse, including interior clamp, anchorage bar and fuse, interior clamp is used for the centre gripping fuse, periphery that the fastening rod cover pressed from both sides including establishing, and interior clamp is equipped with the opening, the base opening of anchorage bar, decide with interior clamping on its base behind the opening that presss from both sides in the anchorage bar passes, just the anchorage bar is made by memory alloy. This kind of structure can guarantee that fuse and interior clamp at any time can firm interlocks, and convenient separation during the outage realizes normal cooperation and separation.
Description
Technical field
This utility model relates to a kind of high-tension fuse structure, particularly to a kind of clip structure.
Background technology
At present, the clip of domestic use is owing to it is frequently necessary to change fuse or being heated during longtime running and the impact of electrodynamic repulsion force easily produces tired and aging, therefore loosening between clip and fuse occur, cause loose contact, contact resistance increase, electric energy loss, even not clamping fuse, have much room for improvement.
Utility model content
The purpose of this utility model, is in that to provide a kind of fuse clip, and it can ensure that fuse and inner clip at any time can firm be engaged, and convenient during power-off separates, it is achieved proper engagement with separate.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of fuse clip, including inner clip, anchorage bar and fuse, inner clip is used for clamping fuse, anchorage bar is set in the periphery of inner clip, inside it is folded with peristome, the base opening of anchorage bar, after the peristome of anchorage bar traverse inner clip, its base is fixed with inner clip, and described anchorage bar is made up of memorial alloy.
Above-mentioned inner clip is several fonts, includes square frame portion successively, tightens portion, clamping part and peristome, and wherein, clamping part is for being clipped in the outer wall of fuse.
Peristome and the square frame portion of above-mentioned inner clip offer fixing hole, and anchorage bar is fixed on the periphery of inner clip through this fixing hole.
Above-mentioned anchorage bar is the convex of base opening, and its top margin is corresponding with the peristome of inner clip, and base is corresponding with the square frame portion of inner clip.
After adopting such scheme, this utility model by being set with the anchorage bar being made up of memorial alloy in the periphery of inner clip, utilize the memorial alloy deformation behavior to variations in temperature, when clip due to Rig up error or load excessive and when causing clip temperature to exceed memorial alloy temperature deformation point, anchorage bar occurrence temperature deformation, inwardly link closely inner clip, reduces the contact resistance between inner clip and fuse, reduce heating, saves energy; When clip carrying is normal, the super-elasticity of memorial alloy can prevent clip from loosening; When fuse is changed in power-off, owing to temperature is reduced to ambient temperature, after the critical temperature of memorial alloy, anchorage bar restPoses, and outwards unclamps inner clip so that fuse is easily extracted. This utility model can overcome existing clip due to it is frequently necessary to change fuse or be heated during longtime running with the impact contacting repulsion and produce tired and aging, causing loosening between clip and fuse, cause the defect that conduction is bad, contact is reliable, well conducting, it is convenient to change.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model composition front elevational schematic;
Fig. 2 is structure of the present utility model composition left view schematic diagram;
Fig. 3 is inner clip of the present utility model and memorial alloy anchorage bar composition structural upright schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1 to Figure 3, this utility model provides a kind of fuse clip, including inner clip 1, anchorage bar 2 and fuse 3, introduces separately below.
The structure of inner clip 1 is several fonts, includes square frame portion successively, tightens portion, clamping part and peristome, can coordinate shown in Fig. 1, wherein, clamping part is for being clipped in the outer wall of fuse 3, and offers fixing hole at peristome and square frame portion also symmetry, is used for fixing anchorage bar 2.
Described anchorage bar 2 is designed as open annular, the overall convex in base opening in the present embodiment, its top margin is corresponding with the peristome of inner clip 1, and the fixing hole on traverse peristome, and the opening on base is through the fixing hole in square frame portion, thus being located on the periphery of inner clip 1; Described anchorage bar 2 is formed by memorial alloy sheet shearing, press process, then through Technology for Heating Processing, and 800 DEG C of quenchings, 500 DEG C of tempering, there is super-elasticity and temperature deformation effect; After fuse temperature exceedes marginal value, anchorage bar 2 deforms upon, and curvature increases, and makes the pressure between the clamping part of inner clip 1 and fuse 3 increase, and after ambient temperature is lower than marginal value, anchorage bar 2 returns to original state.
During use, as depicted in figs. 1 and 2, at normal temperatures, the clamping part of inner clip 1 is pulled open, be clipped on the outer wall of fuse 3, namely complete inner clip 1 and the flexible fastening of fuse 3.
There is temperature deformation and super-elasticity due to anchorage bar 2, when inner clip 1 exceedes memorial alloy temperature deformation point due to Rig up error or the excessive temperature causing inner clip 1 of load, anchorage bar 2 occurrence temperature deformation, inner clip 1 is automatically generated fastening force, reduce the contact resistance between inner clip 1 and fuse 3, thus reducing the heating of inner clip 1, saves energy; When inner clip 1 bears normal current load, the elastic performance of anchorage bar 2 is relied on to prevent inner clip 1 from loosening because of electrodynamic repulsion force; When fuse is changed in power-off, owing to temperature is reduced to ambient temperature, after the critical temperature of the anchorage bar 2 in inner clip 1, anchorage bar 2 restPoses, and outwards unclamps inner clip 1 so that fuse 3 is easily extracted. This utility model can guarantee that fuse, inner clip at any time can firm be engaged, and convenient during power-off separates, it is achieved proper engagement with separate.
Above example is only explanation technological thought of the present utility model; protection domain of the present utility model can not be limited with this; every according to the technological thought that the utility model proposes, any change done on technical scheme basis, each fall within this utility model protection domain.
