An receiving groove is provided inside the lower insulating block. The number of second mounting holes is the same as that of the second mounting columns and they are all opened on the surface of the terminal.

[0008] In an embodiment of the present invention, a plurality of first mounting posts are fixedly connected inside the terminal, and the upper shell and the lower shell are both fixedly connected to the first mounting posts.

[0009] In an embodiment of the present invention, first mounting holes are formed on the surface of the terminal, and the number of the first mounting holes is the same as the number of the first mounting posts.

[0010] In an embodiment of the present invention, the number of the terminals is two, the opposite ends of the two terminals are fixedly connected with fuses, and a fuse connecting portion is fixedly connected between the two fuses.

[0011] In an embodiment of the present invention, a through hole is formed on the surface of the terminal.

[0012] In an embodiment of the present invention, a transparent plate is provided on the top of the upper shell.

[0013] The technical effect of the utility model is that when the fuse burns out, the connection between the two fuses is broken, and the accommodating groove separates the fuses to avoid danger caused by continued power supply after the fuse burns out, making the fuse more durable and having a strong fusing ability, and solving the problem that the space left inside the fuse is large, the withstand voltage strength is low, and the current breaking ability is weak in the event of a short circuit.
