[0025] The present utility model will be further described below with reference to the drawings: As shown in the figure, a wiring terminal includes a housing 1, and also includes a power connection arm 2, and at least part of the power connection arm is disposed inside the housing; a fuse assembly 3, including a housing 31 and a fuse 32, the housing is detachably connected to the housing. When the housing is installed on the housing, the fuse is electrically connected to the power connection arm. One end of the power connection piece is connected to a wire, and the other end pushes the fuse to be in electrical contact with the power connection arm. Further, after the housing is installed in place, the fuse is in electrical contact with the power connection arm through an elastic power connection piece. If a fault occurs at the wiring point, only the power connection piece needs to be taken out and replaced. On the other hand, after the fuse is used, the entire housing can be removed and replaced. Preferably, a fuse is provided on each power connection arm, and the corresponding power connection arm and fuse are connected in series.
[0026] In this embodiment, as shown in the figure, an elastic electrical connection piece 33 is provided on the outer shell. One end of the electrical connection piece contacts the fuse to apply force to electrically connect the fuse to the electrical connection arm. The electrical connection piece can be elastic as a whole, or can form an elastic contact portion for contacting and conducting electricity with the fuse.
[0027] In this embodiment, as shown in the figure, the electrical connection piece is detachably connected to the outer shell. The electrical connection piece can be disassembled and assembled, and can be integrally installed into the outer shell after being connected to the wire.
[0028] In this embodiment, as shown in the figure, a positioning boss 311 is provided on the outer shell, and a positioning groove 331 matching the positioning boss is provided on the electrical connection piece. During installation, the positioning groove of the electrical connection piece can be aligned with the positioning boss, and then preliminary positioning installation can be achieved.
[0029] In this embodiment, as shown in the figure, barbs 332 are provided on the electrical connection piece, and an installation groove 312 matching the barbs is provided on the outer shell. The barbs will cooperate with the inner wall top of the installation groove to play a role in further fixing the installation.
[0030] In this embodiment, as shown in the figure, the electrical connection piece includes an upper piece 30 and a front piece 301. The positioning groove is provided on the upper piece, and the barb is provided on the front piece. The upper piece and the front piece are integrally bent, and the whole can be about ninety degrees, which is more conducive to assembly.
[0031] In this embodiment, as shown in the figure, the electrical connection piece further includes a push piece 302, and the push piece is used to contact the outer wall of the fuse. The push piece contacts the fuse, and the push piece has a certain elasticity to play a pre-tightening role.
[0032] In this embodiment, as shown in the figure, a polygonal operation hole 312 is provided on the outer side surface of the outer shell. It is convenient for tools to be inserted and rotated for installation.
[0033] In this embodiment, as shown in the figure, an installation tube 313 is provided on the outer shell, and at least part of the fuse is installed in the installation tube. One end of the fuse should be exposed for electrical connection to the electrical connection arm.
[0034] In this embodiment, as shown in the figure, a blocking wall 314 is provided in the installation tube. The fuse includes a middle section 320 with a smaller diameter and an outer end 323 with a larger diameter. The blocking wall is provided outside the middle end and is in limit cooperation with the outer end.
[0035] In this embodiment, as shown in the figure, a clamping block 315 is provided on the outer wall of the installation pipe, an installation hole 13 is provided on the housing, a limiting groove 14 is provided on the inner wall of the housing, a part of the installation pipe passes through the installation hole, and the clamping block is matched with the limiting groove. After the installation pipe passes through the installation hole (a through groove for the clamping block to pass through is provided on the installation hole) and rotates, the clamping block will fall into the limiting groove, which can prevent it from being pulled out. The assembly is relatively convenient and only requires rotation.
