In this utility model, a plurality of injection grooves 212 are formed by a plurality of annular protrusions 211 spaced apart, so that after the terminal body 21 and the housing 1 are injection molded, the housing 1 has a protruding part that is inserted into the injection groove 212, thereby preventing the housing 1 and the terminal body 21 from falling off after injection molding, thereby improving the connection stability between the two.

[0024] In one specific embodiment, the first end face of the terminal body 21 has a first threaded groove 22; the first threaded groove 22 is the first wiring part, and a first wiring screw 31 is screwed into the first threaded groove 22. In this embodiment, when it is necessary to connect an external cable to the first wiring part, after the cable is crimped with the lug (or washer), the screwing of the first wiring screw 31 and the first threaded groove 22 plays a locking role for the cable, thereby realizing current carrying. By setting the first wiring part on the end face of the first end of the terminal body 21, it is not necessary to extend an additional part from the first end, thereby reducing the length of the terminal.

[0025] In one specific embodiment, the second end of the terminal body 21 is connected to a wire-passing portion exposed outside the housing 1; the wire-passing portion is a second wiring portion 23; the wire-passing portion is provided with a second threaded groove 231, and a second wiring screw 32 is screwed into the second threaded groove 231. In this embodiment, the wire-passing portion is connected to the end face of the second end and extends away from the end face of the second end. By providing a second threaded groove 231 on the wire-passing portion, and the second threaded groove 231 being perpendicular to the extension direction of the wire-passing portion, it is more convenient for the second wiring portion 23 to be connected to the cable. Specifically, when screwing, after the cable is crimped with the lug (or washer), the screwing of the second wiring screw 32 and the second threaded groove 231 plays a locking role for the cable, thereby realizing current carrying.

[0026] In one specific embodiment, the housing 1 includes a cavity covering portion 11 and a mounting portion 12 sleeved on the outer side wall of the covering portion 11; the terminal body 21 is located inside the cavity, and the first wiring portion and the second wiring portion 23 are exposed outside the cavity; the mounting portion 12 is used to connect to the panel of the device for connecting the current terminal 2.

[0027] In one specific embodiment, the mounting part 12 is provided with a first through hole, the covering part 11 passes through the first through hole and both ends are exposed in the first through hole, and the mounting part 12 is provided with a plurality of screw assemblies 4 at circumferential intervals.

[0030] In one specific embodiment, a dustproof protective cover 7 is detachably connected to the housing 1; the dustproof protective cover 7 is provided with a receiving space for accommodating the first wiring part, and the dustproof protective cover 7 serves to prevent personnel from accidentally touching the live parts.

[0031] Furthermore, the covering part 11 is provided with a slot 111, and the dustproof protective cover 7 is provided with a guide groove 71; the two side walls of the guide groove 71 are engaged in the slot 111. By engaging the two side walls of the guide groove 71 in the slot 111, the dustproof protective cover 7 and the slot 111 can be detachably engaged, so that when it is necessary to connect the cable to the first wiring part, the dustproof protective cover 7 can be removed for easy installation.

[0032] Furthermore, the guide groove 71 is an annular guide groove 71, which includes a sliding section 711 and a snap-fit ​​section 712 connected to the sliding section 711. The width of the sliding section 711 is slightly smaller than the radius of the guide groove 71. The snap-fit ​​section 712 is adapted to the shape of the guide groove 71. Since the dustproof protective cover 7 is made of an elastic material, the guide groove 71 can pass through the sliding section 711, open the sliding section 711, and move into the snap-fit ​​section 712 and snap into it. An anti-detachment protrusion 713 is provided between the sliding section 711 and the snap-fit ​​section 712. The anti-detachment protrusion 713 can keep the guide groove 71 snapped into the snap-fit ​​section 712 without external force.
