Abstract

The utility model discloses a kind of fuse conducting structure being applicable to ring main unit, comprise conductive seat and fuse, conductive seat inwardly has circular groove from outer right wall, circular cross-section along the diverse location place of circular groove groove face inwardly has annular conductive groove and location notch, fuse left end is fixed with conducting circular cylinder, the circular cross-section at the diverse location place of conducting circular cylinder cylinder is fixed by socket respectively spring touch finger and insulation locating ring, conducting circular cylinder to be embedded in circular groove and not to contact circular groove groove face, spring touch finger is connected in conductive trough, the locating ring that simultaneously insulate is connected in location notch.It is little that the utility model has volume, more reliably, and easily processes, the features such as cost is low.

Description

A kind of fuse conducting structure being applicable to ring main unit
Technical field
The utility model relates to a kind of fuse conducting structure.
Background technology
In looped network cabinet equipment, fuse is at middle pressure field protection transformer; good with on-load switch mating protection characteristic; and fuse is for protect more reliably; needs are accomplished better through-flow in conduction, and structure is simpler, because conventional conductive structure is copper coin repeatedly bending; then support with spring steel wire and produce contact; the difficulty of processing of this structure own is large, need multistage punch die, and strain is wayward.
Summary of the invention
For solving the problems referred to above that existing conductive structure exists, the utility model patent provides a kind of fuse conducting structure being applicable to ring main unit, and its technical scheme taked is:
Comprise conductive seat and fuse, conductive seat inwardly has circular groove from outer right wall, circular cross-section along the diverse location place of circular groove groove face inwardly has annular conductive groove and location notch, fuse left end is fixed with conducting circular cylinder, the circular cross-section at the diverse location place of conducting circular cylinder cylinder is fixed by socket respectively spring touch finger and insulation locating ring, conducting circular cylinder to be embedded in circular groove and not to contact circular groove groove face, and spring touch finger is connected in conductive trough, and the locating ring that simultaneously insulate is connected in location notch.
This structure uses spring touch finger to conduct electricity, and contact point is many, and contact is reliable, and dynamic and thermal stability is good, and through-current capability is good, and therefore to have volume little for the utility model, more reliably, and easily processes, the features such as cost is low.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, conductive seat 1 inwardly has circular groove 3 from outer right wall, circular cross-section along the diverse location place of circular groove 3 groove face inwardly has annular conductive groove and location notch, fuse 5 left end is fixed with conducting circular cylinder 6, the circular cross-section at the diverse location place of conducting circular cylinder 6 cylinder is fixed by socket respectively spring touch finger 2 and insulation locating ring 4, conducting circular cylinder 6 to be embedded in circular groove 3 and not to contact circular groove 3 groove face, and spring touch finger 2 is connected in conductive trough, and the locating ring 4 that simultaneously insulate is connected in location notch.The loose contact that insulation locating ring 4 can prevent conductive seat endoporus and fuse conducting face place from causing because of decentraction.Insulation locating ring 4 is dielectric, and electric current can only carry out conducting by spring touch finger 2, so both ensure that the concentric of conductive seat 1 and fuse 5, has the decrement that can ensure spring touch finger 2, thus ensure that the conductive capability of spring touch finger 2.
