Description

High-voltage fuse card seat

Technical Field

The invention relates to the field of fuses, in particular to a high-voltage fuse card holder.

Background

A fuse (fuse) is an electric device that fuses a fuse body by heat generated by itself when a current exceeds a predetermined value, thereby breaking an electric circuit. The fuse melts the melt by the heat generated by the fuse after the current exceeds a specified value for a period of time, so as to cut off the circuit; a current protector is made by applying the principle. The fuse is widely applied to high and low voltage distribution systems, control systems and electric equipment, and is one of the most commonly applied protection devices as a short circuit and overcurrent protector.

The existing clamping seat is completely clamped by a copper spring plate, but the elasticity can be failed after long-time use, the clamping of the fuse is loosened, the problem of poor contact can be caused, the elastic clamping of the root part of the spring plate is completely realized during clamping, and if the root part is broken through total replacement, the fuse clamping seat with high reliability is needed.

Disclosure of Invention

The invention provides a fuse card seat with high reliability, in particular to a high-voltage fuse card seat.

The technical problem solved by the invention can be realized by adopting the following technical scheme:

a high-voltage fuse card seat at least comprises an insulating seat and a clamping device, wherein the clamping device is relatively detachably connected to two ends of the insulating seat;

clamping device comprises base, support, contact plate, wiring board, a pair of curb plate and a pair of spring board, the base can be dismantled and connect on insulating seat, and is a pair of the support is fixed in base upper surface both sides, the contact plate both ends are fixed between the support, and the contact plate bottom is fixed with the base, the wiring board is fixed with the contact plate, and is a pair of the curb plate is fixed at the relative inboard of support, and bottom and contact plate both ends fixed connection, and is a pair of spring board one end respectively with curb plate fixed connection, the support is located spring board other end position opening spout, the spring board other end is located the spout.

The contact plate, the wiring board, the side plate and the spring plate are made of pure copper.

The spring plate is arc-shaped.

And transverse frames are fixed between the supports, and spring clamping plates are fixed on the transverse frames.

The spring clamping plate is of a U-shaped structure, one end of the spring clamping plate is fixed with the cross beam, and the other end of the spring clamping plate is provided with a right-angled bulge.

An opening is formed between the two sides of the spring plate.

The invention has the beneficial effects that: replace traditional centre gripping mode by contact plate, curb plate and spring board, through will separately contact and centre gripping, can not damage contact plate and curb plate, only need change the spring board can, simultaneously through the spring cassette, can make the spring board continue to the fuse centre gripping under the unable circumstances that plays the effect, play dual clamping effect.

Drawings

The invention is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a top view of the present invention.

Fig. 3 is a side view of the present invention.

In the figure: 1-an insulating base; 2-a base; 3-a scaffold; 4-a contact plate; 5-a patch panel; 6-side plate; 7-a spring plate; 8-a transverse frame; 9-spring catch plate.

Detailed Description

Example (b):

referring to fig. 1-3, the high-voltage fuse card seat at least comprises an insulating seat 1 and a clamping device, wherein the clamping device is detachably connected to two ends of the insulating seat 1;

clamping device comprises base 2, support 3, contact plate 4, wiring board 5, a pair of curb plate 6 and a pair of spring board 7, connection can be dismantled on insulating seat 1 to base 2, and is a pair of support 3 is fixed in base 2 upper surface both sides, 4 both ends of contact plate are fixed between

support

3, and 4 bottoms of contact plate are fixed with base 2, wiring board 5 is fixed with contact plate 4, and is a pair of curb plate 6 is fixed at 3 relative inboards of support, and bottom and 4 both ends fixed connection of contact plate, and is a pair of 7 one end of spring board respectively with 6 fixed connection of curb plate, support 3 is located 7 other end position opening spouts of spring board, the 7 other ends of spring board are located the spout.

The contact plate 4, the wiring board 5, the side plate 6 and the spring plate 7 are made of pure copper.

The spring plate 7 is arc-shaped.

And transverse frames 8 are fixed between the brackets 3, and spring clamping plates 9 are fixed on the transverse frames 8.

The spring catch plate 9 is of a U-shaped structure, one end of the spring catch plate 9 is fixed with the cross frame 8, and the other end of the spring catch plate is provided with a right-angled bulge.

An opening is formed between the two sides of the spring plate 7.

In actual use: firstly fix in circuit line position through insulator seat 1, then be connected with the circuit through wiring board 5, then on placing the arrester in spring plate 7, then press the arrester, the arrester both ends are impressed in spring plate 7, contact plate 4 and curb plate 6 contact, the arrester is when impressing spring plate 7, the arrester both ends contact with spring cardboard 9 on the crossbearer 8, spring cardboard 9 extrudees the arrester both ends simultaneously, accomplish the installation.
