Description

A kind of rocket projectile end cap with sealing and conducting function

Technical field

The utility model relates to a kind of rocket projectile end cap with sealing and conducting function, belongs to and plays the arrow technical field.

Background technology

At present, in military, civil rocket, the applying light end cap carrys out the canned motor jet pipe, and need to have some wires to arrive at its afterbody from the rocket top for the control of rocket.For the rocket projectile that increases electric wiring, often adopt the mode of electric connector to connect the instruments such as full bullet and Binding Instrument, detector, need to socket be arranged on end cap in mode through walls.As shown in Figure 1, old-fashioned plate shape end cap dress cylindrical socket, cause the approximately outstanding body of 1/2nd cylinders of installation rear socket, and this structure makes rocket in duties are processed, and hindered by clashing and breaking, so cause short circuit, the fault such as open circuit; Moreover the outstanding body of socket also is unfavorable for the package storage of full bullet.So traditional end cap can't meet current instructions for use.

The utility model content

The purpose of this utility model is in order to solve conventional panels shape rocket projectile end cap subject to damage, to be unfavorable for the shortcomings such as package storage of full bullet, and a kind of rocket projectile end cap with sealing and conducting function is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of rocket projectile end cap with sealing and conducting function of the present utility model, this end cap is hat-shaped structure, the crown position of end cap has socket mounting hole, and the edge of end cap extends annular connected unit towards the crown direction, and the inwall of this annular connected unit is processed with internal thread; The material of main part of end cap is insulating materials, the inside compacting conducting strip of end cap, and this conducting strip makes the annular connected unit outer shroud of end cap and the crown position conducting of end cap, and conducting strip connects terminal screw at the crown place to the crown front end; The inside bottom of annular connected unit is processed with the sealing ring mounting groove;

This end cap is threaded in rocket projectile housing rear end by annular connected unit, and in annular connected unit and rocket projectile housing junction, sealing ring is installed; Be fixedly connected with socket in the socket mounting hole of end cap crown position, gang socket is drawn wire at the inboard end of body and is connected with the inner bookbinding of rocket projectile circuit, and the terminal screw at the crown place of end cap extremely is connected with one of firing circuit.

Beneficial effect:

End cap of the present utility model, by the metallic conduction sheet is pressed in insulating materials, has been realized sealing and conducting function simultaneously, and by ignition circuit with set, detection line separates, and solves multi interference problem, improved security.Simultaneously, the end cover designs of hat-shaped structure has been eliminated after socket is installed the situation of giving prominence to body, protects the accidental injury of socket, has improved the reliability of operability and electric wiring, is beneficial to duties processing and full bullet storage.

The accompanying drawing explanation

The structural representation that Fig. 1 is traditional slab structure end cap;

The structural representation that Fig. 2 is the utility model end cap;

The left view that Fig. 3 is conducting strip in the utility model end cap.

The specific embodiment

Below in conjunction with drawings and Examples, content of the present utility model is described further.

Embodiment

A kind of rocket projectile end cap with sealing and conducting function of the present utility model, as shown in Figure 2, this end cap is hat-shaped structure, and the crown position of end cap has socket mounting hole, the edge of end cap extends annular connected unit towards the crown direction, and the inwall of this annular connected unit is processed with internal thread; The material of main part of end cap is insulating materials, the inside compacting conducting strip of end cap, and this conducting strip makes the annular connected unit outer shroud of end cap and the crown position conducting of end cap, and conducting strip connects terminal screw at the crown place to the crown front end; The inside bottom of annular connected unit is processed with the sealing ring mounting groove;

This end cap is threaded in rocket projectile housing rear end by annular connected unit, and in annular connected unit and rocket projectile housing junction, sealing ring is installed; Be fixedly connected with socket in the socket mounting hole of end cap crown position, gang socket is drawn wire at the inboard end of body and is connected with the inner bookbinding of rocket projectile circuit, and the terminal screw at the crown place of end cap extremely is connected with one of firing circuit.
