The specific implementation is as follows:

referring to fig. 1 to 6, a fuse box capable of being replaced quickly comprises a box body 1, a fuse holder 2 and the box body 1.

Box body 1, the both sides of box body 1 are all fixed to be provided with the pencil and connect 11, have seted up first wiring hole 12 on the pencil connects 11 for the pencil terminal penetrates to its inside from the outside of box body 1, makes the pencil terminal can penetrate the inside of box body 1 from first wiring hole 12, contacts with fuse holder 2, in order to guarantee the unblocked of electric current.

The inside of box body 1 slides and is provided with fuse block 2 for contact with corresponding pencil terminal, the both sides of fuse block 2 lower part all are fixed and are provided with first metal block 21, recess 22 has been seted up to first metal block 21, recess 22's both sides all are fixed and are provided with first spring 23, the fixed second metal block 24 that is provided with of one end of first spring 23, and second metal block 24 can be set up in recess 22 with pincers sliding from top to bottom, second wiring hole 25 has all been seted up on first metal block 21 and the second metal block 24, and first wiring hole 12 and second wiring hole 25 are in same horizontal plane, make under the effect of external force, can coincide second wiring hole 25 on first metal block 21 with second wiring hole 25 on second metal block 24, so that peg graft the pencil terminal in second wiring hole 25, and under the effect of first spring 23, make second metal block 24 have the trend that slides relative to recess 22, until first wiring hole 12, second wiring hole 25 on first metal block 21 and second wiring hole 24 are in second wiring hole 25, and can be in the same horizontal plane through the wiring terminal, the wiring terminal is in order to avoid when the pencil terminal is connected in the certain mode, such a pencil is connected with the terminal, wire harness terminal in order to have been connected in the mode, such a certain horizontal plane, wire harness is connected mode is easily.

Specifically, when the pencil terminal passes first wiring hole 12 and second wiring hole 25, first wiring hole 12, second wiring hole 25 on first metal block 21 and second wiring hole 25 on second metal block 24 just are in same horizontal plane, first wiring hole 12 and second wiring hole 25 are the same axiality this moment, so that the pencil terminal passes, the aperture of having avoided second wiring hole 25 is less than pencil terminal diameter size, need apply great external force just can insert the pencil terminal in second wiring hole 25, and then cause the damage to pencil terminal end.

The box body 1 is hinged with the cover plate 3 and used for driving the fuse holder 2 to slide in the box body 1, so that under the action of the cover plate 3, the fuse holder 2 can automatically slide relative to the second metal block 24 until the second wiring hole 25 on the first wiring hole 12 and the first metal block 21 and the second wiring hole 25 on the second metal block 24 are located on the same horizontal plane.

When the cover plate 3 is covered with the box body 1, a certain pressure is applied to the fuse holder 2 by the cover plate 3, at this time, the lower part of the second metal block 24 abuts against the lower part of the inner cavity of the box body 1, the first metal block 21 slides along the track of the groove 22 and gradually approaches to the upper part of the second metal block 24, so that the first spring 23 is gradually in a compressed state until the first wiring hole 12, the second wiring hole 25 on the first metal block 21 and the second wiring hole 25 on the second metal block 24 are in the same horizontal plane, the wiring harness terminal is sequentially inserted into the second wiring hole 25 from the first wiring hole 12, and finally the cover plate 3 is covered with the box body 1, the pressure applied to the fuse holder 2 by the cover plate 3 by the fuse holder 2 is lost, the first spring 23 is in a recovery state, and a certain thrust is applied to the second metal block 24, so that the second metal block 24 slides in the groove 22 until the wiring harness terminal is completely fixedly connected with the fuse holder 2, and the terminal cannot be easily separated from the fuse holder 2 when the terminal is pulled.

Referring to fig. 2, 3 and 6, fuse fixing grooves 26 have been all seted up to the both sides on fuse holder 2 upper portion, are provided with fault indication fuse 27 in the fuse fixing groove 26, and fault indication fuse 27 is located the top of first metal block 21 for under fault indication fuse 27's effect, the position of mark fault fuse that can be quick, so that staff's maintenance.

To be further described, the wire harness connector 11 is a glan head, and is used for protecting the wire harness terminal, so as to avoid the situation of electric leakage of the wire harness terminal under the condition of frequent screwing.

As shown in fig. 1, fig. 3, fig. 4, fig. 5 and fig. 6, a limiting groove 13 is formed in one side of the box body 1, a clamping groove 14 is formed in the limiting groove 13, the clamping groove 14 extends to the outside of the box body 1, an elastic sheet 31 is fixedly arranged on one side of the cover plate 3, a buckle 32 is fixedly arranged on the elastic sheet 31, the elastic sheet 31 is slidably inserted into the limiting groove 13, and the buckle 32 is clamped in the clamping groove 14, so that the cover plate 3 can be completely fixed on the box body 1 under the effect of the combination of the clamping groove 14 and the buckle 32, and the situation that the box body 1 is easily opened is avoided.

The second embodiment is as follows:

this example is the same as example 1, except that:

in this embodiment, the first spring 23 is not disposed in the groove 22.

Combine as shown in fig. 2, fuse holder 2 passes through telescopic link 4 and box body 1 fixed connection, and the cover is equipped with second spring 41 on telescopic link 4 for under the effect of telescopic link 4 and second spring 41, can reach the effect the same with first spring 23, and can carry out fixed connection with fuse holder 2 and box body 1 through telescopic link 4, avoid fuse holder 2 to take out in following box body 1 easily, and then play the effect of protection to fuse holder 2.

When the cover plate 3 is covered with the box body 1, a certain pressure is applied to the fuse holder 2 by the cover plate 3, at this time, the lower portion of the second metal block 24 abuts against the lower portion of the inner cavity of the box body 1, the first metal block 21 slides along the track of the groove 22, and under the guiding action of the telescopic rod 4, the first metal block 21 gradually approaches to the upper portion of the second metal block 24, meanwhile, the second spring 41 gradually assumes a compressed state until the first wiring hole 12, the second wiring hole 25 on the first metal block 21 and the second wiring hole 25 on the second metal block 24 are in the same horizontal plane, the wire harness terminal is sequentially inserted into the second wiring hole 25 from the first wiring hole 12, finally, the cover plate 3 is covered with the box body 1, the fuse holder 2 loses the pressure applied to the fuse holder 2 by the cover plate 3, the second spring 41 assumes a restored state, a certain upward pushing force can be applied to the lower portion of the fuse holder 2, the fuse holder 2 is under the guiding action of the fuse holder 4, the fuse holder 2 does not slide relative to the second metal block 21, and the wire holder 2 can not easily slide relative to the second wiring holder, and the wire holder 2, no matter how the wire harness terminal is easily connected with the telescopic rod.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
