Description

Fuse with concatenation function

Technical Field

The utility model belongs to the technical field of the fuse, especially, relate to a fuse with concatenation function.

Background

The metal conductor is used as a melt to be connected in series in a circuit, and when overload or short-circuit current passes through the melt, the melt is fused due to self heating, so that the circuit is broken. The fuse has simple structure and convenient use, and is widely used as a protective device in an electric power system, various electrical equipment and household appliances;

in some factories, fuses are required to be connected in series for use due to more switches of control equipment, management is convenient, the fuses are single bodies in the market, and if the fuses are required to be connected in series, the fuses are required to be fixed one by one to be tidy, so that the control equipment is very troublesome to install.

SUMMERY OF THE UTILITY MODEL

The utility model provides a fuse with concatenation function, this fuse with concatenation function has solved the problem that the aforesaid provided.

In order to achieve the above object, the utility model discloses a fuse with concatenation function's concrete technical scheme as follows: the utility model provides a fuse with concatenation function, includes the fuse casing, the fillet hole has been seted up to one side of fuse casing, and the opposite side threaded hole, and the fuse casing is two kinds in addition, and the fillet hole is all seted up to one both sides, and the screw hole is all seted up to another kind of both sides, the fillet hole has cup jointed the blanking cover, the screw hole cover has joint spare.

Further, a top cover is installed at the opening at the top of the fuse shell.

Further, the blanking cover includes gasket and latex head, the latex head is installed to the one end of gasket, the first surface of latex is pegged graft with the fillet hole on the fuse casing.

Further, the joint spare includes double-screw bolt and plastics dop, screw hole threaded connection on double-screw bolt and the fuse casing, the plastics dop that is used for splicing the fuse is installed to the outer end of double-screw bolt.

Furthermore, the fuse shell is made of flame-retardant plastic.

Borrow by above-mentioned technical scheme, the utility model provides a fuse with concatenation function. The method at least has the following beneficial effects:

this fuse with concatenation function, fuse housing divide into three kinds, one kind is that one side sets up fillet hole opposite side and sets up the screw hole, and the second kind is that both sides all set up the fillet hole, and the third kind is that both sides all set up the screw hole, just so can install in the screw hole to the fuse series connection concatenation more than three groups through joint spare, and the completion that relaxes like this assembles the concatenation to the fuse.

FIG. 4 is a fourth schematic illustration provided by the present example;

fig. 5 is a fifth schematic diagram provided in this example.

In the figure: 1 fuse shell, 2 top cover, 3 screw holes, 4 round angle holes, 31 clamping pieces, 311 screw bolts, 312 plastic clamping heads, 41 blanking covers, 411 gaskets and 412 latex heads.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following figures are combined to describe the fuse with the splicing function in further detail.

As shown in fig. 1-2, fuse with concatenation function, 1 two liang concatenations of fuse casing or splice more than three and four groups, just must set up screw hole 3 and fillet hole 4 with fuse casing 1 differentiation when rising to 1 concatenation of fuse casing more than three groups, a fuse casing 1 sets up fillet hole 4 opposite side for one side and sets up screw hole 3, the second kind is that 1 both sides of fuse casing set up fillet hole 4, the third kind is that 1 both sides of fuse casing all set up screw hole 3, just so can let 1 concatenation of fuse casing more than three.

The above description is at least three, and there are many combinations according to actual operation.

As shown in fig. 3-4, in the fuse with splicing function of the present invention, the stud 311 of the clamping member 31 and the threaded hole of the fuse housing 1 are mounted when they are to be spliced, when two fuse housings 1 are spliced, the fuse housing 1 with the clamping member 31 and the fuse housing 1 with the round hole 4 are clamped with the corresponding positions, and the plastic clamp 312 of the clamping member 31 is inserted into the round hole 4 to realize clamping;

because the middle of the plastic clamping head 312 is provided with a space and a groove structure close to the stud 311, the plastic clamping head 312 can realize a locking state after being inserted into the round-corner hole 4 to complete clamping and fixing of every two fuse shells 1;

since the fuse housing 1 located at the outermost end of the fuse housing 1 when splicing is to avoid that the inner part of the fuse housing 1 enters ash or the plug 41 with the latex head 412 is plugged in the round hole 4 because of the round hole 4, the plug 41 should be applied to the fuse housing 1 with the round hole 4 at the outermost end when splicing the fuse.

As shown in fig. 5, the fuse with splicing function of the present invention shows that three fuse housings 1 are spliced, wherein the fuse housing 1 in the middle of the drawing can be provided with round holes 4 on both sides, and at least one side of the fuse housings 1 at both ends in the drawing is provided with a threaded hole 3 for realizing the clamping;

in the second case, the two sides of the middle fuse housing 1 are both provided with threaded holes 3, and at least one side of the fuse housing 1 at the two ends in the drawing is provided with the fuse housing 1 with a round-angle hole 4;

therefore, the number of the arrangement combinations is large, and the arrangement combinations are matched according to the specific number of the fuse shells 1 in practical use.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
