Abstract
The utility model discloses an improvement structure of fuse end cap, but the fuse includes insulating tube, diagonal sets up the fuse -element in the insulating tube and coordinate in the end cap at insulating tube both ends, concave part in end cap bottom surface middle part forms. The indent position is inboard in the pipe wall of insulating tube, forms soldering tin slot -Filler between the lateral wall of interior concave part and end cap. When the end cap is established to insulating pipe box, but the tip of fuse -element is arranged in soldering tin slot -Filler. The utility model discloses simple structure, material cost's efficiency is realized reducing by the quantity of the soldering tin that can significantly reduce.
Description
Technical field
This utility model relates to the technical field belonging to circuit over-current protection device, the improved structure of a kind of electric fuse end cap.
Background technology
The production of current miniature fuse-links, it is that scolding tin is preset in end cap, fuse structure as shown in Figure 1, the insulation tube 1 ' of open at both ends mounts a fusable links 2 ', fusable links 2 is arranged in diagonal positions, fusable links 1 ' bending is fixed on the tube wall of insulation tube end, then makes scolding tin 4 ' melt end cap 3 ' heating, is welded together to form in the insulation tube being provided with fusable links is inserted end cap.For this kind of mode of production, the end cap of current miniature fuse-links is flat, when fusable links is disposed in diagonal in insulation tube, effective welding scolding tin is mainly the scolding tin near insulation tube inwall and the scolding tin of the gap location between insulation tube lateral surface and end cap medial surface, and the scolding tin being in end cap central region does not play effective welding effect.For in actual production, for reducing soldering tin amount, the effect of the soldering tin amount reducing end cap central region can be reached, but also will necessarily reduce the soldering tin amount near insulation tube inwall (the tin soldering liquid height for starting at bottom end cap) simultaneously, also reduce the scolding tin height of gap location between insulation tube lateral surface and end cap medial surface, fusable links contacts minimizing with scolding tin, so will reduce the reliability of welding.
Nature resource is limited, the current energy-saving and cost-reducing common recognition having become as the whole society, in miniature fuse-links industry, industrialized mass production, on the premise of not reducing quality and properties of product, reduces the consumption Ye Shige specialized factory of the materials such as metal material and constantly studies and pursue.In view of this, the design people does not attains perfect caused many disappearances and inconvenience in the structure design of existing electric fuse end cap, and deeply conceives, and actively research improvement has a fling at and develops and design this creation.
Utility model content
This utility model relates to the improved structure of a kind of electric fuse end cap, its simple in construction, can greatly reduce the consumption of scolding tin, it is achieved reduce effect of material cost.
In order to reach above-mentioned purpose, solution of the present utility model is:
The improved structure of a kind of electric fuse end cap, electric fuse includes the fusable links that insulation tube, diagonal are set up in insulation tube and the end cap being matched with insulation tube two ends, forms an inner fovea part in the middle part of end cap bottom surface.
Further, inner fovea part is positioned at inside the tube wall of insulation tube, forms scolding tin filling slot between inner fovea part and the sidewall of end cap.
Further, during the sheathed end cap of insulation tube, the end of fusable links is positioned in scolding tin filling slot.
After using said structure, this utility model defines inner fovea part in the middle part of the bottom surface of end cap, eliminate the waste that middle part scolding tin is caused, only need to set a certain amount of scolding tin at the scolding tin filling slot midpoint of end cap, the end of fusable links will contact scolding tin smoothly, ensure that the reliability of welding, the consumption of scolding tin can be greatly reduced, it is achieved reduce effect of material cost.

Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated.
As in figure 2 it is shown, the improved structure of a kind of electric fuse end cap of this utility model announcement, this electric fuse includes insulation tube 1, fusable links 2, end cap 3 and is located at the scolding tin 4 in end cap 3 bottom interior wall.Wherein, mounting fusable links 2 in two ends form uncovered insulation tube 1, the two ends afterbody of fusable links 2 bends bottom insulation tube 1, and fusable links 2 is arranged in diagonal positions.And two end caps 3 are matched with the two ends of insulation tube 1, end cap 3 is metal end caps, can be copper cap.Scolding tin 4 on contact end cap 3 bottom surface, the two ends inwall of fusable links 2, is fixed on end cap 3 after being made scolding tin 4 melted by heating end cap 3 thus be coated on the end of fusable links 2.
Of the present utility model the improvement is that, form concave inward structure in the middle part of the bottom surface of end cap 3, in the middle part of end cap bottom surface, form an inner fovea part 31, as shown in Figures 2 to 4, be that end cap 3 bottom surface of plane is inwardly stamped and formed out an inner fovea part 31 originally.Inner fovea part 31 is positioned at inside the tube wall of insulation tube, and fusable links 2 end is through the gap inner fovea part and tube wall.Can form scolding tin filling slot 32 between inner fovea part 31 and the sidewall of end cap, when insulation tube 1 sheathed end cap 3, the end of fusable links 2 is positioned in this scolding tin filling slot 32.When end cap 3 is connected, the scolding tin 4 of some amount is set at scolding tin filling slot 32 midpoint of the bottom surface of end cap 3, also in scolding tin filling slot 32 after scolding tin 4 is melted, fusable links 2 end is coated in scolding tin, and fusable links 2 is connected on end cap by scolding tin 4, ensure that the reliability of welding, meet electric fuse conducts function simultaneously.
In this utility model, because the scolding tin being in end cap central region does not play effective welding effect, inner fovea part 31 is defined in the middle part of the bottom surface of end cap, eliminating the waste that middle part scolding tin is caused, only need to set a certain amount of scolding tin at scolding tin filling slot 32 midpoint of end cap, the end of fusable links 2 will contact scolding tin 4 smoothly, ensure that the reliability of welding, simple in construction, can greatly reduce the consumption of scolding tin, it is achieved reduce effect of material cost.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as without departing from patent category of the present utility model.
