Abstract
The utility model discloses a fuse, which comprises a vacuum glass tube and copper caps connected to two ends of the glass tube. A fuse wire is arranged in the glass tube; metal pins are arranged on the copper caps and comprise horizontal parts which extend to the two ends in the horizontal direction, arc bending parts and lead-out parts which vertically and downwards extend; the summation of the lengths of the glass tube and the copper caps is the same as the distance between the two lead-out parts, so that the length of the whole fuse is greatly reduced; and in addition, the metal pins can be used without being bent and are easy in connection.
Description
Technical field
The utility model belongs to the overload protection element, particularly a kind of fuse that shields when overtension.
Background technology
Existing fuse mainly is made of airtight insulation shell and the copper cap that is connected the housing two ends, be provided with in the housing level to fuse, the copper cap is provided with metal pins, mostly metal pins is level yearning two ends extension, the length overall of fuse is the length that shell length adds two terminals like this, and whole insurance filament is long, and it is bigger to take up room, and metal pins bending 90 degree need be welded on the circuit board then when using, operation is trouble quite.
The utility model content
The purpose of this utility model provides a kind of fuse little, ease of connection that takes up room.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of fuse, the copper cap that comprises the glass tube of vacuum and be connected the glass tube two ends, be provided with fuse in the glass tube, the copper cap is provided with metal pins, described metal pins is yearned for the horizontal part that extends at two ends, the bend of arc and the lead division that vertical yearning is extended down by level and is constituted, and glass tube is identical with the distance between two lead divisions with the length sum of copper cap.
Wherein, be filled with carbon dioxide in the described glass tube, described fuse tilts to be located in the glass tube.
The beneficial effects of the utility model are: metal pins is yearned for the horizontal part that extends at two ends, the bend of arc and the lead division that vertical yearning is extended down by level and is constituted, glass tube is identical with the distance between two lead divisions with the length sum of copper cap, the length of whole like this fuse reduces greatly, and metal pins need not bending and just can use, and connects to become easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, the utility model discloses a kind of fuse, comprise the glass tube 1 of vacuum and the copper cap 2 that is connected glass tube 1 two ends, be filled with carbon dioxide in the described glass tube 1, be provided with fuse 3 in the glass tube 1, described fuse 3 tilts to be located in the glass tube 1, copper cap 2 is provided with metal pins, described metal pins is yearned for the horizontal part 41 that extend at two ends by level, the bend 42 of arc and the vertical lead division 43 of yearning for extension down constitute, glass tube 1 is identical with the distance between two lead divisions 43 with the length sum of copper cap 2, the length of whole like this fuse reduces greatly, and metal pins need not bending and just can use, and connects to become easy.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
Claims (2)
