Each dent is clamped with the extending tongue 25 of the clamping device, so that each fusible core is reliably and stably arranged in the fusing cavity, and the connection effect of the fusible cores is ensured.

The sliding groove is provided with a first inclined portion 26, one end of the ejection rod 27 close to the protruding tongue 25 is provided with a second inclined portion, and the first inclined portion 26 and the second inclined portion are abutted against each other. Specifically, the sliding tray is equipped with and runs through stretch out the tongue main part, the groove width of sliding tray with the biggest shaft diameter isowidth of pop-up rod makes pop-up rod 27 can run through perpendicularly at the in-process that presses stretch out tongue 25, makes it realizes to stretch out tongue 25 under the extruded effect stretch out the tongue and move backward, relieve to each the effect of the joint of leaning on of fusible core. Be equipped with first slope 26 in the sliding tray, the pop-up pole is close to the one end of first slope 26 is equipped with the second slope, first slope 26 with the second slope just to setting up and laminating each other. After the clamping button is pressed, the second inclined part of the ejection rod extrudes the first inclined part 26 to enable the extension tongue to face one side of the reset spring, so that the extension tongue 25 retracts to relieve the clamping of the fusible core, and at the moment, the fusible core can be replaced.

The two sides of the extending tongue 25 are provided with clamping blocks, and the clamping blocks are symmetrically arranged on the two sides of the extending tongue 25. Specifically, the clamping blocks are arranged on two sides of the extending tongue 25, so that the clamping blocks cannot be separated from the clamping cavity in the process of extending the extending tongue. The symmetrically-arranged clamping blocks enable the two sides of the extending tongue to extend horizontally all the time, so that the extending tongue does not deviate, the extending tongue is aligned with each dent of the fusible core all the time, and the extending tongue is clamped with the dent. In this embodiment, the depth of the indentation corresponds to the distance the protruding tongue protrudes out of the fusing chamber, so that the protruding tongue can be reliably connected with the indentation.

The power supply portion is provided with a plurality of power supply contacts 43. Specifically, each that power supply portion was equipped with power supply contact 43, each the contact is equipped with screw and deposit the wire casing, the screw link up perpendicularly deposit the wire casing. In the process of being connected with the wire, deposit the wire of inslot be in deposit under the extrusion of screw with deposit the fixed adapter of wire casing, guarantee the wire with the effect of power supply portion power supply also can guarantee that the effect that switches on is better, also can guarantee to change more convenience to the wire. In addition, the screw is preferably a cross screw. In this embodiment, the structure of the power supply socket can also adopt the existing technology, namely: the effect of connecting the wire with the power supply part can be adopted, and the structure connected with the wire is not described in detail.

To sum up, the fuse of the utility model is arranged in the fusing chamber by adopting the fusible core, and the two ends of the fusible core are respectively connected with the contact heads of the power supply part in a clamping manner, so that the fuse can be fused by current in the fusible core, and the fusing effect of the fuse is realized; the power supply seat and the clamping body can be stably and reliably connected by adopting the matching use of the locking hook and the locking groove, the better continuous power supply effect of the fuse can be effectively ensured, and the protection effect of the fuse can also be ensured; the clamping plates are adopted to perform adaptive clamping according to the size of the clamping cavities extending into the clamping cavities, so that the clamping plates can be ensured to adapt to different connecting rods, and the clamping plates and the clamping cavities can be matched to ensure that more application scenes can be possessed; the stand columns of the clamping plates and the abutting springs are mutually nested to form a powerful clamping device for the clamping plates, so that the clamping plates are tightly attached when the connecting rods are clamped, and the conducting effect between each clamping plate and each clamping plate is realized; through adopting being equipped with the indenture on the just right fusible core of latch, the indenture extends along the length direction of each fusible core for the fusible core can carry out the joint with latch, and indenture and each latch joint make each fusible core be located each fusing appearance intracavity all the time, guarantee good joint, also guarantee that the intercommunication effect between each latch reaches the best state.
