Background

The fuse is an overcurrent protector. The fuse is mainly composed of a fuse body, a fuse tube, an additional filler and the like. When the fuse protector is used, the fuse protector is connected in series in a protected circuit, when the current of the protected circuit exceeds a specified value and a certain time passes, the fuse body is fused by the heat generated by the fuse body, so that the circuit is disconnected, and the protection effect is achieved. The electric appliance which takes the metal conductor as the melt body and breaks the circuit is connected in series in the circuit, when overload or short-circuit current passes through the melt body, the melt body is heated and fused, thereby playing a certain protection role for a power system, various electrical equipment and household appliances. The fuse has the inverse time delay characteristic, and when the overload current is small, the fusing time is long; when the overload current is large, the fusing time is short. Therefore, the fuse can not be fused and can be continuously used until the current returns to normal within a certain overload current range.

The existing tubular fuse comprises a base, a connecting assembly and a fuse body, a binding post and a stud are arranged on the connecting assembly, the connecting assembly is connected with the base through the stud, a clamping portion comprises a pair of clamping pieces and a clamping rod, the clamping pieces are used for clamping the end portion of the fuse body and clamp the fuse body, the clamping rod is located on the outer side of the clamping pieces and clamps the two clamping pieces, the bottom of the clamping rod is generally fixed and cannot move, and the port portion can move. Then, when the melt is replaced, the melt may not be matched with the opening of the clamping piece due to the difference of models, so that the melt is too tight or too loose, and finally poor contact is caused.

Further, the fuse-element includes the body, and both ends set up insulating connecting plate, then are provided with the contact on the connecting plate, and the contact is arranged in the clamping piece.

Furthermore, the base comprises two side plates, a pin hole and a pin shaft assembly are respectively arranged at two ends of each side plate, a pin shaft is arranged in each pin shaft assembly, the pin shaft can rotate to be horizontal and vertical to the side plates, and when the pin shaft rotates to be vertical to the side plates, the pin shaft can be inserted into the pin holes of the side plates of the adjacent base.

Furthermore, a concave part is also arranged on the side plate, and the pin shaft assembly is positioned in the concave part; the pin shaft assembly further comprises a horizontal shaft, the horizontal shaft is parallel to the side plates, the end portion of the pin shaft is hinged to the horizontal shaft and can rotate around the horizontal shaft, a horizontal limiting plate is arranged at the end portion of the pin shaft by the side plates, and the limiting plate is used for keeping the pin shaft horizontal.

Furthermore, a pair of clamping bulges are further arranged in the concave part and are respectively positioned on two sides of the pin shaft, the end parts of the clamping bulges are made of deformable materials, and the clamping bulges are used for fixing the pin shaft in the concave part.

According to the above technical scheme, the utility model has the advantages of it is following: the utility model can adapt to melts of different models, when the contact of the melt is wide, the clamping rod can be moved downwards, when the contact of the melt is narrow, the contact can be moved upwards, and because the thickness of the clamping piece is gradually reduced from top to bottom, the clamping piece and the clamping rod can be always kept to be tightly matched, and the clamping rod slides out along the clamping piece; two fuses can arrange the concatenation use, and the concatenation is convenient.
