Abstract
The utility model relates to a high voltage transmission and distribution equipment part, in particular to a fuse support with a cylindrical high voltage fuse in high voltage transmission distribution equipment. A pair of opposite through holes is arranged on an elastic contact plate of the fuse support, flat slots passing through the centers of the through holes are further arranged at the positions of the through holes, a C-shaped spring is arranged on the outer side of the elastic contact plate, and a flat portion is arranged at the two ends of the spring. When a plane with a material center line of the spring is parallel to a bottom plate, the two ends of the spring can run through the inner side of the elastic contact plate from the outer sides of the two through holes, the end of the spring can not exit from the through holes after the spring passes through and rotates for 90 degrees around the centers of the through holes, simultaneously two sides of the spring are compressed on the outer side of the elastic contact plate. The fuse support is simple in structure and convenient in installation, and can compress the outer side of elastic contact plate through the spring, thereby guaranteeing the contact pressure of the fuse support with the end of the fuse, and enhancing the reliability of conductive connection.
Description
Technical field
The utility model relates to a kind of high pressure equipment for power transmission and distribution parts, specifically is a kind of fuse support that cylindrical high-tension fuse is installed in the high pressure equipment for power transmission and distribution.
Background technology
Common high-tension fuse is cylindrical, the current-carrying part at its two ends is installed on a pair of fuse support in the mode of inserting when mounted, common fuse support generally includes a pair of elastic contact blade that adapts with the fuse end shape, and two elastic contact blade lower ends connect as one by the egative film of one section level.This structure in use, the fuse end is inserted between the elastic contact blade and is promptly finished installation, elastic contact blade is connected with conduction between the fuse and relies on the elastic properties of materials of elastic contact blade to guarantee fully, less or the contact pressure of conduction contact can't be guaranteed when causing distance between contact wafers excessive when elastic properties of materials power owing to contact distortion, thus the reliability that conduction connects reduced.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of fuse support of conduction connection reliability when improving fuse and installing is provided.
Fuse support of the present utility model includes a pair of elastic contact blade, and two elastic contact blade lower ends connect as one by the egative film of one section level; Have a pair of relative through hole on two elastic contact blades, also have a flat groove by the through hole center at the through hole position, the width of flat groove is less than through-hole diameter, and the length of flat groove is greater than through-hole diameter; The spring that a C shape is arranged in the arranged outside of elastic contact blade, two end tools, one section of the having flat part of spring, the thickness of this flat part is less than the width of above-mentioned flat groove, simultaneously the width of flat part is greater than through-hole diameter, make spring the end from flat groove pass and rotate to an angle after can't withdraw from; And, when the plane at the material center line place of spring is parallel with egative film, two ends of spring can penetrate into the elastic contact blade inboard from two above-mentioned through hole outsides, and penetrate and can't withdraw from through hole around the end of through hole center half-twist rear spring when spring, the dual-side of spring is pressed on the outside of elastic contact blade simultaneously.
Described two elastic contact blades upper end is provided with the flange that outwards is bent to level, and the outer ledge of flange is provided with groove, and when the dual-side of above-mentioned spring was pressed on the elastic contact blade outside, this dual-side was stuck in the groove.
A bight of the outer ledge of described flange is provided with lead angle, so that the side to spring leads when spring rotates.
Fuse supporting structure of the present utility model is simple, easy for installation, and it can be oppressed the elastic contact blade outside by spring, to guarantee itself and the contact pressure of fuse end, has improved the reliability of conduction connection; In addition, because spring has prevented that being blocked in after the fuse installation above the fuse in use fuse is deviate from support.

Embodiment
As shown in the figure, the fuse mounting bracket includes the egative film 2 of a pair of elastic contact blade 1, two elastic contact blade lower end by one section level and connects as one; Have a pair of relative through hole 11 on two elastic contact blades, also have a flat groove 12 by the through hole center at the through hole position, the width of flat groove is less than through-hole diameter, and the length of flat groove is greater than through-hole diameter; The spring 3 that a C shape is arranged in the arranged outside of elastic contact blade, two end tools, one section of the having flat part 31 of spring, the thickness of this flat part is less than the width of flat groove 12, simultaneously the width of flat part is greater than through hole 11 diameters, make spring the end from through hole and flat groove pass and rotate to an angle after can't withdraw from.
As Fig. 1, Fig. 2, shown in Figure 3, when melting when mounted, spring 3 is positioned at level, and this moment, two ends of spring 3 can penetrate into the elastic contact blade inboard from two through holes and the flat groove outside; As Fig. 4, shown in Figure 5, and after spring penetrates around through hole center half-twist, this moment, through hole can't be withdrawed from the end of spring, simultaneously the dual-side 32 of spring is pressed on the flange 13 in the outside of elastic contact blade, and is stuck in the groove 14 at flange edge.A bight of the outer ledge of flange 13 is provided with lead angle 15, so that the side 32 to spring leads when spring 3 rotations.
