[0035] The seat body 10 and the integrated cover 20 are integrally formed and connected into one body through the turning part 30. The integrated cover 20 can rotate around the turning part 30 to close the seat body 10 and press the fuse tube.

[0036] The seat body 10 is provided with a clamping groove 130, and the integrated cover 20 is provided with a clamping head 210; the integrated cover 20 and the seat body 10 are fixedly connected through the cooperation between the clamping groove 130 and the clamping head 210.

[0037] The seat body 10 is provided with two connecting grooves 110 for assembling the conductive connecting pieces 40, and the two connecting grooves 130 are provided with a tube body accommodating groove 120. In use, the end caps of the fuse tube are arranged in the corresponding connecting grooves 110, and the tube part of the fuse tube is accommodated in the tube body accommodating groove 120.

[0038] The connecting groove 110 has a square groove structure, and the sidewall of the groove body is provided with an elastic buffer presser 1110, which divides the connecting groove 110 into a card slot 1120 and a heat dissipation slot 1130.

[0039] The elastic buffer pressure foot 1110 comprises a vertical part 1111, a deformation part 1112 and a horizontal part 1113 which are integrally formed; the vertical part 1111 is fixedly connected to the side wall of the connecting groove 110, the horizontal part 1113 is parallel to the groove bottom of the connecting groove 110, and the deformation part 1112 is obliquely arranged between the vertical part 1111 and the horizontal part 1113.

[0040] The horizontal part 1113 and the groove bottom of the connecting groove 110 are at a certain distance, that is, the bottoms of the card slot 1120 and the heat dissipation slot 1130 are communicated with each other. The horizontal buffer part 420 of the connecting groove 110 is used for assembling the conductive connecting piece 40, so that the distance between the horizontal part 1113 and the groove bottom of the connecting groove 110 is preferably equal to the thickness of the matching part of the conductive connecting part 40, so as to increase the stability of the connection.

[0041] The conductive connecting piece 40 comprises a vertical clamping pipe part 410, a horizontal buffer part 420 and a vertical pin part 430; the vertical clamping pipe part 410 and the vertical pin part 430 are respectively arranged on both sides of the horizontal buffer part 420.

When the vertical pin part 430 of the fuse seat is inserted into the circuit, the external force is transmitted to the horizontal buffer part 420 through the vertical pin part 430; under the action of the horizontal buffer part 420, the deformation part 1112 of the elastic buffer pressure foot 1110 is elastically deformed, and at the same time, the horizontal part 1113 slides to the middle on the horizontal buffer part 420 of the conductive connecting piece 40, so as to buffer the force received by the vertical pin part 430, thereby avoiding affecting the electrical connection quality between the fuse tube and the clamping pipe circular groove 4130.
