Description
Technical field
The present invention relates to a kind of cylindrical member syndeton preventing inner lead to be wound around, belong to and play arrow mounting technology field.
Background technology
At civilian bullet arrow new product day by day in the R&D process of intelligent direction development, often can run into such class problem: some being positioned at projectile nose Guidance and control parts need to be drawn from afterbody by solid propellant rocket in the middle part of body for the wire carrying out Starting Technical state parameter and set.Existing technical scheme is generally that the igniter by being arranged on rocket chamber's head realizes continuing of wire, namely in igniter, preset the wire needed, body general assembly in conjunction with time is connected presetting wire in Guidance and control component leads and igniter, thus form the wire line of needs.Guidance and control parts are generally realize being connected by screw thread and rocket engine, and wire is wound around that the such as solder joint that may cause stressedly gets loose, conductor insulation sheath damages the problems such as the stressed generation fracture of even wire mutually when connecting by screw thread rotation.
Summary of the invention
In the middle of when the object of the invention is to solve two cylindrical member threaded engagement can there is the problem be mutually wound around in multiply docking wire, and provide a kind of cylindrical member syndeton preventing inner lead to be wound around.
The object of the invention is to be achieved through the following technical solutions:
A kind of cylindrical member syndeton preventing inner lead to be wound around of the present invention, comprises front connector, expansion bracket, connector, circlip, adapter ring, rear connectors and rear end connector assembly;
Expansion bracket is the intersection that is arranged in same plane and many flexible connection with connecting rod be arranged in order forms;
Adapter ring is the cirque structure that sidewall is processed with axial location ring;
Rear connectors center has stepped throughhole, and the through hole internal diameter of small-bore, rear connectors rear end and the circular ring structure external diameter of adapter ring match, and wide-aperture through hole front end, rear connectors front end is processed with back-up ring mounting groove;
The rear end of adapter ring is inserted in the stepped throughhole of rear connectors, makes adapter ring by the ladder platform screens backward of rear connectors, in the back-up ring mounting groove of rear connectors stepped throughhole, installs circlip, make adapter ring by circlip screens forward; The front end surface of adapter ring fixes one end of expansion bracket telescopic direction by connector, the other end of expansion bracket telescopic direction and front connector are fixed; The front end of rear end connector assembly is inserted the inner ring of adapter ring and fixes with its screw thread, sealed by seal washer between rear end connector assembly and adapter ring, the inner ring of wire through adapter ring is drawn in the front end of rear end connector assembly, and through the side of expansion bracket, be finally connected with the connector assembly of front connector inside.
The course of work
Because front connector, expansion bracket, connector, adapter ring and rear end connector assembly are for being fixedly connected with, when current connector and the docking of rear connectors screw thread, front connector is relative to expansion bracket, connector, between adapter ring and rear end connector assembly, circumferencial direction is synchronous, rear connectors independently rotates, and in screw thread docking operation, expansion bracket shrinks under front connector and the inside squeezing action of rear connectors, the axis shift change before realizing between connector and rear connectors.
Beneficial effect:
Syndeton of the present invention processing is simple, uses reliable, and in the middle of when solving two cylindrical member threaded engagement, the problem be mutually wound around can occur multiply docking wire, improves efficiency of assembling and product assembly quality.
Accompanying drawing explanation
Fig. 1 is the connection diagram of cylindrical member syndeton of the present invention;
Wherein, connector before 1-; 2-expansion bracket; 3-connector; 4-circlip; 5-adapter ring; 6-seal washer; 7-rear connectors.
Embodiment
Below in conjunction with drawings and Examples, content of the present invention is further described:
Embodiment
A kind of cylindrical member syndeton preventing inner lead to be wound around of the present invention, as shown in Figure 1, comprises front connector 1, expansion bracket 2, connector 3, circlip 4, adapter ring 5, rear connectors 7 and rear end connector assembly 8;
Expansion bracket 2 for the intersection that is arranged in same plane and many flexible connection with connecting rod be arranged in order form;
Adapter ring 5 is processed with the cirque structure of axial location ring for sidewall;
Rear connectors 7 center has stepped throughhole, and the through hole internal diameter of small-bore, rear connectors 7 rear end and the circular ring structure external diameter of adapter ring 5 match, and wide-aperture through hole front end, rear connectors 7 front end is processed with back-up ring mounting groove;
The rear end of adapter ring 5 is inserted in the stepped throughhole of rear connectors 7, make adapter ring 5 by the ladder platform screens backward of rear connectors 7, in the back-up ring mounting groove of rear connectors 7 stepped throughhole, circlip 4 is installed, makes adapter ring 5 by circlip 4 screens forward; The front end surface of adapter ring 5 fixes one end of expansion bracket 2 telescopic direction by connector 3, the other end and the front connector 1 of expansion bracket 2 telescopic direction are fixed; The front end of rear end connector assembly 8 is inserted the inner ring of adapter ring 5 and fixes with its screw thread, sealed by seal washer 6 between rear end connector assembly 8 and adapter ring 5, the inner ring of wire through adapter ring 5 is drawn in the front end of rear end connector assembly 8, and through the side of expansion bracket 2, be finally connected with the connector assembly of front connector 1 inside.
Because front connector 1, expansion bracket 2, connector 3, adapter ring 5 and rear end connector assembly 8 are for being fixedly connected with, when current connector 1 and the docking of rear connectors 7 screw thread, front connector 1 is relative to expansion bracket 2, connector 3, between adapter ring 5 and rear end connector assembly 8, circumferencial direction is synchronous, rear connectors 7 is independent to be rotated, and in screw thread docking operation, expansion bracket 2 shrinks under front connector 1 and the inside squeezing action of rear connectors 7, the axis shift change before realizing between connector 1 and rear connectors 7.
