Abstract
The utility model relates to an insulating terminal used for a laser gyro, in particular to a minitype high-voltage sealed insulating terminal used for the laser gyro in an aircraft inertial navigation system. The insulating terminal is characterized in that the side wall of a plug is provided with a connecting lead so that the space in the height direction can be saved, the structure is compact and the space occupying is small. The plug and the socket are fixedly connected with each other by a countersunk head screw so as to reduce the occupying space to the maximum degree. An insulating sheet is clamped between the socket and the plug; when the socket and the plug are fixedly arranged, the insulating sheet is extruded, the air between the socket and the plug is extruded empty, the insulating sheet is made of rubber material which has higher insulation performance than the air; therefore, the two diagonal inserting pins can realize the requirement of bearing the 6000V medium high-voltage at shorter distance, and reduces the volume of the whole insulating terminal simultaneously.

Summary of the invention
The objective of the invention is to overcome the existing bulky shortcoming of high pressure sealing connector, the laser gyro that a kind of compact conformation is provided, takes up room little minitype high voltage sealed insulation terminal, this terminal can be realized the function of sealing and High-Voltage Insulation in very little space.
Realize the technical scheme of the object of the invention: a kind of laser gyro minitype high voltage sealed insulation terminal, comprise socket, plug, be symmetrically arranged with some contact pins on the socket, the position of the corresponding contact pin of plug is provided with pin hole, use the polytetrafluoroethylene press seal around the pin hole, the sidewall of plug is provided with the connection lead, is provided with the insulating trip that contact pin can pass between on the socket and plug, is with sealing ring on the socket.
Aforesaid a kind of laser gyro is fastenedly connected by sunk screw between socket, the plug with minitype high voltage sealed insulation terminal.
Aforesaid a kind of laser gyro connects lead and is provided with insulating sleeve outward with minitype high voltage sealed insulation terminal, and the model that connects the lead employing is AF2500.2.
Aforesaid a kind of laser gyro minitype high voltage sealed insulation terminal, plug epoxy resin press seal.
Aforesaid a kind of laser gyro adopts iron-cobalt-nickel glass sealing alloy material with minitype high voltage sealed insulation terminal, contact pin.
Aforesaid a kind of laser gyro minitype high voltage sealed insulation terminal, socket symmetric is provided with four contact pins, and uniform each other spacing is 5.5mm, and diagonal pitch is 7.77mm, the about 4mm of distance of pin and socket sidewall.
Aforesaid a kind of laser gyro minitype high voltage sealed insulation terminal, insulating trip, sealing ring all adopt silastic material.
Effect of the present invention is: the sidewall of plug is provided with the connection lead, can save the space of short transverse, make compact conformation, take up room little.Adopt sunk screw to be fastenedly connected and to reduce to greatest extent to take up room between plug and the socket.Insulating trip is clipped between the socket and plug, when socket and plug fixedly mounts, insulating trip is stressed, air between the socket and plug is emptied, insulating trip adopts elastomeric material, the insulating properties of rubber is higher than air, just can realize bearing than short distance the requirement of 6000V medium high pressure like this between two contact pins in diagonal angle, simultaneously the volume of whole insulated terminal is reduced.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 1, a kind of laser gyro comprises the socket 1, the plug 2 that are fastenedly connected by sunk screw with minitype high voltage sealed insulation terminal.The shell of socket 1 is cylindrical, is symmetrically arranged with four contact pins 8 above the plate of socket 1, is symmetrically arranged with four root bead pins 11 below the plate, is used for bonding wire.The shell of plug 2 also is cylindrical, and the position of the corresponding contact pin 8 of plug 2 plates is provided with pin hole 7, uses the polytetrafluoroethylene press seal around the pin hole 7, and the connection lead 5 that it is AF2500.2 that plug 2 side wall of outer shell are provided with four models connects the lead 5 outer insulating sleeves that are provided with.The plate of socket 1, plug 2 is glass sintering layer 10.Be provided with the insulating trip 3 that contact pin 2 can pass between socket 1 and the plug 2, be with sealing ring 4 on the socket 1.Use the epoxy resin press seal above the plug 2.Contact pin 8 adopts iron-cobalt-nickel glass sealing alloy material.Four uniform each other spacings of contact pin 8 are 5.5mm, and diagonal pitch is 7.77mm, the about 4mm of distance of pin and socket sidewall.Insulating trip 3, sealing ring 4 all adopt silastic material.
The sidewall of plug is provided with the connection lead, and the space that can save short transverse is stretched out in stretching out direction and can adjusting as required of lead from the side, make compact conformation, take up room little.The thickness of lead can be selected according to the size of electric current.Insulating trip is clipped between the socket and plug, when tightening the mounting screw of plug, insulating trip is stressed, and the air between the socket and plug is emptied, the insulating properties of rubber is higher than air, just can realize bearing than short distance the requirement of 6000V high pressure like this between diagonal angle two pins.This design of insulating trip is that this insulated terminal is than the little key of existing available connector volume.Sealing ring adopts silastic material, and diameter of section Φ 1mm can satisfy seal request and can satisfy the requirement in 10 years of system's storage again.
