Abstract
A glass electrode plug for industrial and non-industrial bridge wire detonators is provided. The conventional electrode plug for bridge wire detonator is usually produced from plastic by die-casting and has environmental limits on application. In order to solve the above problem, the utility model provides glass electrode plug with good resistance to high temperature, chemical corrosion and oil corrosion. It comprises electrode wires (1,2) and connection bridge wire (3). The electrode wires (1,2) are sintered at a certain distance inside a glass base (4). The electrode wires (1,2) are parallel to each other in said glass base (4). The utility model can increase the reliability and security of bridge wire detonator and is widely used for industrial and non-industrial bridge wire detonators.
Description
Affiliated technical field
The utility model belongs to the bridge silk detonator of industry and non-technical, relates in particular to the electrode plug of bridge silk detonator special use.
Background technology
Traditional detonator adopts chemistry to ignite mostly, often lost efficacy easily by such environmental effects, and reliability is low, and has bigger potential safety hazard.Widely used in recent years bridge silk detonator adopts electrode plug to make initiator, and when giving the minor diameter resistance wire element, promptly connect the bridge silk when applying the high voltage high energy pulse, resistance wire explodes because of the big energy of release fast, this energy chemical explosion sequence of detonating.This initiator is subjected to such environmental effects less, and is safer reliable.Though at present common electrode plug can satisfy the instructions for use of bridge silk detonator, mostly be the plastics punch die and cast, can not high temperature resistant and acid-alkali-corrosive-resisting, the ability that adapts to abominable working environment is relatively poor.
Summary of the invention
The utility model purpose is the deficiency that exists at prior art, and the bridge silk detonator electrode plug of a kind of anti-higher temperature, acid-alkali-corrosive-resisting is provided.
The purpose of this utility model realizes like this: comprise wire electrode 1,2 and connect bridge silk 3, it is characterized in that wire electrode 1,2 keeps at a certain distance away sintering in glass seat 4.Described wire electrode 1,2 is parallel to each other.And an end is mutually neat with glass seat 4, and the other end is longer than glass seat 4, connects bridge silk 3 and glass seat 4 wire electrode 1,2 connections of neat end mutually.
And wire electrode 1,2 adopts alloy can cut down silk.Connect bridge silk 3 and adopt NiCr alloy silk, with raising electrode plug operating temperature,
The utility model is used for bridge silk formula detonator, and when applying the 0.2A safe current, the detonating primer of misfiring in 5 minutes has certain secure threshold.And when applying the 1A firing current, get angry detonating primer in 30 seconds.
The utility model is formed by glass and metal sintering, deft design, the technology uniqueness can guarantee under the Environmental Technology condition of 230 ℃, 4 hours and 250 ℃, 12 hours, electrode plug does not melt, and connects do not come off anti-higher temperature, acid and alkali-resistance and oil of bridge silk and wire electrode and corrodes.
Description of drawings
Fig. 1 is the utility model structure and connection diagram.
The specific embodiment
Describe in detail below in conjunction with accompanying drawing.
As Fig. 1, two parallel electrodes silks, 1,2 sintering of electrode plug are in glass seat 4, and in order to reach the purpose with glass sintering, but the wire of selecting for use is a raft alloy silk.Electrode plug blank cylindrical behind the sintering grinds off unnecessary part through grinding, and the part that the electrode plug blank is unnecessary grinds off; Wire electrode 1,2 smooths of beveled electrode plug blank end face can improve the soldering reliability that connects bridge silk 3; Connect bridge silk 3 usefulness NiCr alloy silks, and use high melting point solder to be welded to connect bridge silk 3 to reach resistant to elevated temperatures requirement; Earlier scolder is cut into measure-alike fritter during welding, can better controlled spot size and uniformity.
Protection domain of the present utility model is not limited to shown in the accompanying drawing.
