Description
Technical field
The present invention relates to a kind of explosion type Closing Switch, is a kind of normal open switch, belongs to the electric switch technical field, is applicable to various automatically controlled occasions, is specially adapted to the control automatically of ship electricity.
Background technology
Existing conventional low contactor mainly is to make moving contact realize contact closure through certain stroke by electromagnetic mechanism, under the certain situation of current-carrying part unit volume ampacity, because traditional contactor needs the driving mechanism of the relative current-carrying part several times of volume, causes the overall dimension of traditional contactor and quality can't further dwindle always.And the conventional low contactor can't bear the environment of HI high impact vibration owing to be subjected to the restriction of self structure, volume and quality.For example, as the protection switch that uses in the ship electric control, it is fast to require switch to have closing speed, and volume is little, in light weight, characteristics such as shock-resistant and reliability height, and the existing mechanical switch can not meet the demands.
Summary of the invention
The objective of the invention is: provide a kind of simple in structure, closing speed is fast, size is little, in light weight, shock-resistant and explosion type Closing Switch that reliability is high.
Technical scheme of the present invention is as follows:
A kind of explosion type Closing Switch, it comprises an insulating sleeve, and an axis hole shoulder is arranged in its inner chamber, and a side of this axis hole shoulder has a fixed contact as main circuit conductor, and opposite side has a base as conductor; This base intracavity is equipped with igniter, moving contact from outside to inside; This moving contact has a sliding cavity between the end face of the end face of an end of axis hole shoulder and fixed contact; An isolation valve is arranged between one end of moving contact and the axis hole shoulder; The inner chamber of fixed contact and base has a groove, is equipped with one in this groove respectively and electrically contacts ring.
Described explosion type Closing Switch, the ring that electrically contacts of its fixed contact moves the endoporus mouth diameters of first end greater than the moving contact external diameter, so that moving contact enters electrically contacting in the ring of fixed contact in the clear by movable contact.
Described explosion type Closing Switch, its initial inside diameter and moving contact that electrically contacts ring is an interference fit.
Described explosion type Closing Switch, its isolation valve are annular, and hoop is a plurality of grooves of radial even distribution outward in it, and interior ring diameter is less than the moving contact external diameter.
Described explosion type Closing Switch, the difference of the inside radius of the axis hole shoulder in its insulating sleeve inner chamber and the outer radius of moving contact is greater than the thickness of isolation valve.
Described explosion type Closing Switch has air vent hole on its fixed contact outer face.
Described explosion type Closing Switch, its igniter is made up of electric detonator, electric detonator sheath and igniter base.
Described explosion type Closing Switch, the plastic insulating material of its isolation valve is selected polyformaldehyde for use, or polyamide, or polytetrafluoroethylene.
The basic functional principle of explosion type Closing Switch: it is to utilize the characteristics that the explosive charge reaction speed is fast, the acting ability is strong, and when electric system needed protection, the triggering signal ignition charge exploded moving contact rapidly and closes, and reaches the purpose of protection electric system.That is: because electric detonator in the enormous impact power that explosion time produces, makes the moving contact that is in base intracavity overcome the resistance generation axial motion of isolation valve, and moving contact contacts with fixed contact by the ring that electrically contacts in the compression fixed contact groove rapidly, switch is closed fully.
Advantage and technique effects such as that the present invention has is simple in structure, resistance to impact is high, closing speed is fast, closed reliability is high and easy to maintenance; The explosion type Closing Switch is applicable to various automatically controlled occasions, is specially adapted to the control automatically of ship electricity.The impact that the explosion type Closing Switch can be born hundreds of gravity inertial acceleration is: when switch did not come into operation, moving contact was between igniter and isolation valve, and its motion is restricted; When switch was in closed operating state, moving contact was subjected to electrically contacting the restoring force effect of ring and isolation valve, and for this reason, the impact that switch can tolerate hundreds of gravity inertial acceleration of moment can not change state yet.
