Abstract
The utility model relates to the technical field of electronic components, in particular to a novel test safety pipe, which comprises a glass pipe, opening sealing caps, an electric fuse, electronic pins and silicon dioxide particles, wherein the electric fuse is arranged in the glass pipe, the silicon dioxide particles are arranged in the glass pipe, both ends of the glass pipe are provided with the opening sealing caps for forming a sealed cavity, the outer side of the opening sealing caps is provided with the electronic pins, and both ends of the electric fuse are connected with the opening sealing caps and the electronic pins. The structural design is scientific. When the voltage is too high, and the current is too strong, the phenomenon of pipe blasting of the transparent glass pipe can not occur, and injury can not be brought to test personnel.
Description
Technical field:
The utility model relates to the electronic components technical field, refers in particular to a kind of novel test protective tube.
Background technology:
In the electronic components field, protective tube also is fuse, and it is made up of transparent glass tube, the cap body that seals, electronics pin, electric fuse, and fuse is also referred to as fuse, and it is a kind of being installed in the circuit, guarantees the electric elements of circuit safety operation.The effect of fuse is: when circuit breaks down or be unusual, be accompanied by electric current and constantly raise, and the electric current that raises might damage some important devices or valuable device in the circuit, also might burn circuit even cause fire.If correctly settled fuse in the circuit, so, fuse will current anomaly be elevated to certain height and certain in, electric current is cut off in self fusing, thereby plays the effect of protective circuit safe operation.
The test of customary risks pipe is to adopt high pressure energising test, has now in the test of protective tube a problem, be exactly work as overtension, when electric current is excessive, the phenomenon of transparent glass tube booster can take place, and can bring injury to the tester.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, and a kind of novel test protective tube is provided, and its scientific structure design is worked as overtension, when electric current is excessive, the phenomenon of transparent glass tube booster can not take place also, can not bring injury to the tester.
For achieving the above object, the utility model adopts following technical scheme, it comprises glass tube, seal cap, electric fuse, electronics pin, silica dioxide granule, electric fuse places in the glass tube, be provided with silica dioxide granule in the glass tube, the two ends of glass tube are provided with seals cap and forms a seal chamber, and the outside of sealing cap is provided with the electronics pin, the two ends of electric fuse with seal cap and the electronics pin is connected.
Described silica dioxide granule is sandstone.
The described cap that seals is a metalwork.
Described glass tube with seal cap by the glue adhering and sealing.
The utility model beneficial effect is: electric fuse places in the glass tube; be provided with silica dioxide granule in the glass tube; work as overtension; when electric current is excessive; silica dioxide granule can absorb the heat of generation; silica dioxide granule has the non-conducting performance simultaneously, and the phenomenon of transparent glass tube booster so just can not take place, and can not bring injury to the tester.
Description of drawings:
Fig. 1 is the structural representation of prior art test protective tube;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a decomposition texture schematic diagram of the present utility model.
Embodiment:
See that Fig. 1 is to shown in Figure 3: the utility model comprises glass tube 1, seals cap 2, electric fuse 3, electronics pin 4, silica dioxide granule 5, it is characterized in that: electric fuse 3 places in the glass tube 1, be provided with silica dioxide granule 5 in the glass tube 1, the two ends of glass tube 1 are provided with seals seal chamber of cap 2 formation, the outside of sealing cap 2 is provided with electronics pin 4, the two ends of electric fuse 3 with seal cap 2 and electronics pin 4 is connected.
Described silica dioxide granule 5 is sandstone, and it is convenient that sandstone are got material, and production cost is low, when electric current was excessive, sandstone can absorb the heat of generation, and sandstone have the non-conducting performance simultaneously, the phenomenon of transparent glass tube booster so just can not take place, and can not bring injury to the tester.
The described cap 2 that seals is metalwork.
Described glass tube 1 with seal cap 2 by the glue adhering and sealing.
The protective tube that will the test sandstone of packing into, be made into testing tube of the present utility model after, test, if stable performance meets the requirements, just the protective tube of this model can be come into operation.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
