The installation department includes first installed part and second installed part, first installed part is equipped with the spout, the second installed part is equipped with spacing post, during the concatenation of first installed part and second installed part, spacing post is spacing in the spout.
The casing is equipped with first spout, spacing post is located first spout when the installation department installs in the casing time limit.
The casing is internally provided with an elastic pressing sheet, and the elastic pressing sheet compresses the fusible core when the installation part is installed on the casing.
The elastic pressing sheet comprises an upper pressing sheet and a lower pressing sheet, and the upper pressing sheet and the lower pressing sheet clamp the fusible core.
The casing is equipped with the terminal, elasticity preforming one end and fusible core electric connection, the other end and terminal electric connection.
The shell comprises an upper shell and a lower shell, and the upper shell and the lower shell are connected through screws.
The mounting portion is at least partially exposed outside the housing when the mounting portion is mounted on the housing.
When the mounting part is mounted on the shell, the mounting part is exposed out of the outer part of the shell and is trapezoidal, the part close to the shell is a trapezoidal narrow part, and the part far away from the shell is a trapezoidal wide part.
The utility model has the advantages that: the utility model provides a pair of fuse of removable fusible core need not to take off the circuit with the fuse and disassemble in the occasion that needs to change the fusible core, only need take off the installation department change the fusible core can, convenient operation, the cost is reduced.

Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Referring to fig. 1, a fuse of removable fusible core, including casing 1, the installation department 2 that is used for installing fusible core 3, casing 1 includes casing 101 and casing 102 down, goes up casing 101 and casing 102 threaded connection down, and the installation department 2 partially exposes in casing 1 when installing in casing 1, and the exposure part is trapezoidal, is close to casing 1 part and is trapezoidal narrow portion, keeps away from casing 1 part and is trapezoidal wide portion, and the installation department is extracted to the trapezoidal part of gripping with the hand when conveniently changing the fusible core.
Referring to fig. 2-4, the installation part 2 is provided with a limiting cavity 7 of a limiting fusible core, the installation part 2 comprises a first installation part 201 and a second installation part 202, the first installation part 201 is provided with a sliding groove 6, the second installation part 202 is provided with a limiting column 5, and when the first installation part 201 and the second installation part 202 are spliced, the limiting column 5 is limited in the sliding groove 6.
Referring to fig. 1-5, a plurality of limiting grooves 11 are formed in a shell 1, a bump 4 corresponding to the limiting grooves 11 is formed in an installation portion 2, a first sliding groove 10 is formed in the shell 1, a limiting column 5 is located in the first sliding groove 10 when the installation portion 2 is installed in the shell 1, and the shell 1 and the installation portion 2 are detachably installed. Be equipped with the elasticity preforming 8 in the casing 1, this elasticity preforming 8 includes preforming and preforming down, goes up preforming and the tight fusible core 3 of lower preforming clamp, and the casing is equipped with terminal 9, and elasticity preforming 8 is conductive metal, and the electrically conductive department contact of its one end and fusible core 3's tip, and the other end passes through the metal busbar and is connected with terminal 9.
When fusible core 3 fuses and needs to be changed, grip the trapezoidal part that installation department 2 exposes casing 1 with the hand and upwards pull out, make lug 4 break away from spacing recess 11 to make spacing post 5 slide along spout 6 until installation department 2 breaks away from casing 1, take off fusible core 3 that has fused and change, arrange 6 lapse of spout in with spacing post 5 during the installation, and make elasticity preforming 8 press from both sides tight fusible core 3, the installation is accomplished when lug 4 is spacing in spacing recess 11.
The examples should not be construed as limiting the invention, and any non-inventive modifications based on the spirit of the invention should be construed as within the scope of the invention.
