Abstract

The utility model discloses an anti-interference socket connector for an airborne multi-way data bus. The anti-interference socket connector adopts the structure that a first insulator and a third insulator both arranged left and right in the axial direction of a jack in a contact manner are coaxially sleeved on the jack; an outer conductor is coaxially sleeved on both a second insulator and a fourth insulator which are arranged left and right in the axial direction of the outer conductor in a contact manner; intermediate conductors are coaxially and tightly fixed between the first insulator and the third insulator as well as between the second insulator and the fourth insulator respectively; one end of the fourth insulator is fixedly connected with a knurled circular ring positioned in the inner chamber of the outer conductor; and three bayonet pins are uniformly fixed on the outer wall of the outer conductor in the circumferential direction. In the utility model, as the intermediate conductors are arranged between the jack and the outer conductor, three-layer conduction is adopted and insulating medium serves as filling, the anti-interference socket connector can completely well adapt to special coaxial cables used in the aerospace field to satisfy the technical requirements of aerospace communication, and can also be used in coordination with electronic systems on weapon platforms such as chariots, vessels and the like.

Description

The anti-interference socket connector of airborne multiplex data bus

Technical field

The utility model relates to a kind of radio-frequency (RF) coaxial socket connector, is used for airborne multiplex data bus.

Background technology

Traditional radio frequency (RF) coaxial connector current-carrying part is made up of shell and inside and outside two-layer conductor, is with insulator in the conductor, and outer conductor is installed outside insulator, and outer conductor is with the swivel nut fixed housing, and the radio frequency (RF) coaxial connector of this structure is most widely used.At present, the development of the airborne multiplex data bus technology of China is backward relatively, when traditional radio frequency (RF) coaxial connector is used for airborne multiplex data bus, its shield effectiveness is low, be not suitable for the demanding aircraft airborne electronic system of shield effectiveness, performance index do not reach the requirement of current radar, radio station, airborne carrier-borne electronics and microwave communication yet.

Summary of the invention

The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of precision height, good reliability is provided, can be fit to the anti-interference socket connector of airborne multiplex data bus of high shielding requirements.

The technical solution adopted in the utility model is: have coaxial jack and outer conductor, along jack axially about first insulator arranged of contact and the 3rd insulator with outer shaft sleeve on jack, outer conductor with outer shaft sleeve along its axially about on contact second insulator and the 4th insulator arranged, coaxially between first insulator, the 3rd insulator and second insulator, the 4th insulator closely fix a middle conductor; The fixedly connected knurling annulus that is arranged in the outer conductor inner chamber of one end of the 4th insulator; Outer wall along described outer conductor circumferentially evenly fixedly installs three bayonet locks.

The utility model is owing to be provided with middle conductor between jack and outer conductor, the tactic pattern of the inside and outside two-layer conduction of current-carrying part abandoning tradition connector adopts three layers of conduction, fills with dielectric between three layers of conductor.When the utility model is connected with contact pin connector, have two inner wires and corresponding insulation body in connector inside, this connector can be connected well with the special coaxial cable that space industry uses fully, to satisfy the specification requirement of space communication, also can be the supporting use of electronic system on the weapon platforms such as battlebus, naval vessel.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;

Fig. 1 is that the utility model structure is partly cutd open figure;

Among the figure: 1. jack; 2. first insulator; 3. second insulator; 4. the 3rd insulator; 5. the 4th insulator; 6. middle conductor; 7. outer conductor; 8. knurling annulus; 9. nut; 10. internal tooth lock washer; 11. weld tabs; 12. bayonet lock.

Embodiment

As shown in Figure 1, the utlity model has jack 1 and outer conductor 7, jack 1 and outer conductor 7 are coaxial, first insulator 2 and the 3rd insulator 4 coaxial fixed jackets on jack 1, and first insulator 2 and the 3rd insulator 4 along jack 1 axially about contact layout.Outer conductor 7 coaxial fixed jackets on second insulator 3 and the 4th insulator 5, and second insulator 3 and the 4th insulator 5 along outer conductor 7 axially about contact layout.Coaxially between first insulator 2, the 3rd insulator 4 and second insulator 3, the 4th insulator 5 closely fix a middle conductor 6, promptly second insulator 3, the 4th insulator 5 fixed jackets are on middle conductor 6, and middle conductor 6 fixed jackets are on first insulator 2, the 3rd insulator 4.

The fixedly connected knurling annulus 8 of one end of knurling annulus of the fixed installation in outer conductor 7 inner chambers 8, the four insulators 5, knurling annulus 8 is with spacing the 4th insulator 5.Nut 9, internal tooth lock washer 10 and weld tabs 11 are installed on outer conductor 7 outer walls, and nut 9, internal tooth lock washer 10 and weld tabs 11 are spun on respectively on the outer conductor 7.On outer conductor 7 outer walls, along circumferentially evenly fixedly installing three bayonet locks 12, promptly three bayonet locks are 120 ° of distributions.When the utility model and pin connector when inserting, bayonet lock 12 slips into location hole along the spiral guide slot that has on the pin connector, thereby realizes locking, makes contact more reliable, realizes plugging together fast separation.

Middle conductor 6 adopts the tin bronze material with higher-strength and superior elasticity, with coating the LJ-2004 protective agent after its surface gold-plating with the use ability that increases its anti-environment and anti-plug and the ability that increases the service life, reduces resistivity, avoids getting rusty.Each insulator all adopts the less relatively polytetrafluoroethylene of dielectric constant as dielectric material.Be fixing middle conductor 6 better, can boss be set on middle conductor 6 and be used to install corresponding insulation.For preventing that middle conductor 6 from rotating, be pressed in the corresponding insulator after middle conductor 6 can being rolled straight burr.
