Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a clamping type fuse. Background Art

[0002] A fuse is also called a fuse. The IEC127 standard defines it as a "fuse-link". It is an electrical component installed in a circuit to ensure the safe operation of the circuit. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As a short circuit and overcurrent protector, they are one of the most commonly used protective devices. Common fuses require certain tools such as screwdrivers to connect to wires, which is very inconvenient, and existing fuses cannot protect them after installation. To this end, we propose a snap-on fuse. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a snap-in fuse.

[0004] The technical solution adopted by the utility model to solve its technical problems is a clip-on fuse, comprising a base, a connecting mechanism is installed on the top of the base, and the connecting mechanism is composed of a clip-on seat, a connecting plate, a threaded rod, a gasket, a threaded sleeve and an arc spring piece. A group of symmetrical clips are fixedly installed on the top of the base, a group of symmetrical gaskets are installed on the top of a group of clip-on seats, a connecting plate is welded at the outer wall of a group of clip-on seats, a threaded rod is welded at the plate wall of the connecting plate, the threaded rod passes through a group of gaskets of a limiting wire, a threaded sleeve is threadedly connected at the rod wall of the threaded rod, and the threaded sleeve is located on the top of the gasket.

[0005] By adopting the above technical scheme, when the fuse body is clamped, since a connecting mechanism is installed on the top of the base, the connecting mechanism is composed of a clamping seat, a connecting plate, a threaded rod, a gasket, a threaded sleeve and an arc spring piece. Since a group of symmetrical clamping seats are installed on the top of the base, and a group of symmetrical arc spring pieces are installed on the top of the clamping seat, after a person inserts one end of the fuse body into the arc spring pieces, the arc spring piece is used to squeeze and fix one end of the fuse body to achieve clamping of the fuse body. Since a threaded rod is welded on the outside of the clamping seat, and the threaded rod passes through a group of gaskets, after a person wraps the external wire around the threaded rod, the wire is located between the gaskets, and a threaded sleeve is threadedly connected to the rod wall of the threaded rod. The person twists the threaded sleeve so that the threaded sleeve squeezes the gasket to fix the wire.

[0006] Specifically, it also includes a limiting mechanism, and the limiting mechanism is installed on the top of the base.

[0007] By adopting the above technical solution, the fuse body can be protected by the limiting mechanism.

[0008] Specifically, the limiting mechanism is composed of a concave shell, a positioning rod, a positioning hole and a locking bolt. A group of symmetrical positioning rods are fixedly installed on the shell wall of the concave shell, a group of symmetrical positioning holes are opened on the top of the base, and the positioning rods are located in the positioning holes. A group of symmetrical locking bolts are threadedly connected to the outer wall of the base, and the other end of the locking bolt is located on one side of the positioning rod.

[0009] By adopting the above technical solution, when protecting the fuse body, a limiting mechanism is installed on the top of the base, and the limiting mechanism is composed of a concave shell, a positioning rod, a positioning hole and a locking bolt. Since a group of symmetrical positioning holes are opened on the top of the base, a group of symmetrical positioning rods are welded on the shell wall of the concave shell, so that the positioning rods are inserted into the positioning holes, and the locking bolts are turned so that the locking bolts squeeze the positioning rods to fix the concave shell, thereby protecting the fuse body.

[0010] Specifically, a fuse body is plug-connected between the card connectors.

[0011] By adopting the above technical solution, it is convenient to clamp the fuse body.

[0012] Specifically, a through hole connected to an external bolt is provided on the top of the base.

[0013] By adopting the above technical solution, the base can be conveniently fixed by passing the external bolts through the through holes.

One end of the fuse body 5 is squeezed and fixed to realize the clamping of the fuse body 5. Since a threaded rod 403 is welded on the outside of the clamping seat 401, and the threaded rod 403 passes through a group of gaskets 404, after the personnel wrap the external wire around the threaded rod 403, the wire is located between the gaskets 404.
