Technical field
The utility model relates to the technical field of voltage transformer, and is relevant with the fuse device for ejecting structure of band striker hole mode voltage transformer.
Background technology
In the prior art, the fuse device for ejecting of band striker hole mode voltage transformer as shown in Figure 1, the end of fuse 10 is enclosed within on the cover for seat 20 of back, the bottom of back cover for seat 20 has the through hole 201 that passes for striker 30, back cover for seat 20 is installed on the fixed head 50 by two shell fragments 40, cooperate Fig. 2 to shown in Figure 4, the through hole 201 of corresponding back cover for seat 20 also has the through hole 501 that passes for striker 30 on the fixed head 50, and fixed head 50 is by screw 60 and once connect inserts 70 and be fixed on the instrument transformer 80.During use, with the through hole 201 of the through hole 501 of the through hole 901 on striker 30 perforated shrouds 90, fixed head 50 and back cover for seat 20 end near fuses 10, again striker 30 is pushed away to fuse 10, the end of striker fuse 10, fuse 10 is ejected from back cover for seat 20, be convenient for changing fuse 10.
Anatomize said structure, be not difficult to find that there is following deficiency in it:
One, shell fragment 40 is too hard, when changing fuse 10, is not easy to eject fuse 10;
Two, be connected by two shell fragments 40 between cover for seat 20 and the fixed head 50 of back, the flexibility of two shell fragments 40 is often inconsistent, cause back cover for seat 20 to produce skew, produce dislocation after making between the through hole 501 of the through hole 201 of cover for seat 20 and fixed head 50, make striker 30 can't pass through hole 501 and through hole 201 smoothly, the bump operation has some setbacks even can't operate;
Three, the useful life of shell fragment 40 not long, rupture easily through long-term compression, influence the normal use of device;
Four, shell fragment 40 adopts rivets 401 to be fixed on back cover for seat 20 and the fixed head 50, cooperates shown in Figure 4ly, needs eight rivets altogether, and number of rivets is many, waste man-hour, inconvenience is installed.
In view of this, the inventor improves at the structure of existing fuse device for ejecting, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of fuse device for ejecting with striker hole mode voltage transformer, and it is installed easily, and the life-span is long, and uses easy to operate, smooth and easy.
In order to reach above-mentioned purpose, solution of the present utility model is:
The fuse device for ejecting of band striker hole mode voltage transformer comprises back cover for seat, spring and fixed head; Back cover for seat is the end that is enclosed within fuse, and the bottom of back cover for seat is protruded and formed connection part, forms the centre bore that runs through for striker on the bottom of back cover for seat and the connection part; Spring be arranged on fuse the end and the back cover for seat the bottom between; Fixed head is fixed together by screw and back cover for seat, and the centre bore of corresponding back cover for seat also forms the through hole that runs through for striker on the fixed head, and fixed head also is fixed on the instrument transformer.
Above-mentioned spring is a carbon spring steel wires.
Form screw on the connection part of above-mentioned back cover for seat, form unthreaded hole on the fixed head, screw passes unthreaded hole and is screwed onto in the screw, and fixed head and back cover for seat are fixed together.
The said fixing plate by screw with once be connected inserts and be fixed on the instrument transformer.
After adopting such scheme, the utility model compared with prior art has following advantage:
One, replace shell fragment by spring, good springiness ejects fuse easily;
Two, the long service life of spring, the normal use of assurance device;
Three, is connected by screw between connection part and the fixed head of back cover for seat, the centre bore that has guaranteed back cover for seat aligns with the through hole of fixed head and does not misplace, and makes striker can pass through hole and centre bore smoothly, clash into operate smooth and easy;
Four, spring directly is provided with between back cover for seat and the fixed head, need not to add in addition fixing, then adopts screw between cover for seat and the fixed head, and is easy for installation.

Embodiment
As shown in Figure 5, be preferable case study on implementation of the present utility model.
The fuse device for ejecting of band striker hole mode voltage transformer comprises back cover for seat 1, spring 2 and fixed head 3.
Cooperate Fig. 6 to shown in Figure 8, back cover for seat 1 is the end that is enclosed within fuse 10, and the bottom of back cover for seat 1 is protruded and formed connection part 11, forms the centre bore 12 that runs through for striker 30 on the bottom of back cover for seat 1 and the connection part 11.
Fixed head 3 is the L type, the riser of fixed head 3 is fixed together by screw 4 and back cover for seat 1, concrete fixed structure can be: form screw on the connection part 11 of back cover for seat 1, form unthreaded hole on the riser of fixed head 3, screw 4 passes unthreaded hole and is screwed onto in the screw, and fixed head 3 and back cover for seat 1 are fixed together.The centre bore 12 of corresponding back cover for seat 1 also forms the through hole 31 that runs through for striker 30 on the riser of fixed head 3.And, the transverse slat of fixed head 3 also by screw 5 with once be connected inserts 6 and be fixed on the instrument transformer 80.
