Abstract

The invention relates to a radio-frequency three-coaxial connector, comprising a plug and a socket. The interfaces of the plug and the socket are respectively composed of an external conductor, a middle conductor and an internal conductor, the three conductors are coaxial and insulated by insulators. The external conductor does not transfer signals, protects the signals from outside disturb, restrains the radiation of the signals of the system, and also improves the transmission capability and the anti-interference capability of the data transmission system. The socket is connected with the plug by three bayonets or screw threads or the socket is connected with the plug in push type. The radio-frequency three-coaxial connector has the advantages of convenient connection, reliable locking, steady electrical property, rapid plugging or unplugging, good electrical properties and good mechanical property, applicability to connecting soft symmetric radio frequency cable, three coaxial cables for radio equipments and the radio frequency loops of electronic devices, in particular to the radio frequency application requiring high shielding property.

Description

Radio frequency three coaxial connector

Technical field

The present invention relates to a kind of connector, specifically is the three coaxial connector in a kind of suitable the loop of rf.

Background technology

Along with the popularization of computer, data transmission system and local area network (LAN), electromagnetic interference is becoming the crucial difficult point problem that people must solve.Guarantee the communication quality and the stability of transmission line, improve the antijamming capability of communication loop, essential method is to adopt shielding construction.Existing radio frequency (RF) coaxial connector is made up of internal and external conductor, and internal and external conductor is formed a loop, and outer conductor plays certain function of shielding simultaneously, but its shielding properties is poor, and signal transmission attenuation is bigger.

Summary of the invention

In order to overcome the low deficiency of coaxial connector shielding properties in the prior art, the purpose of this invention is to provide a kind of shielding properties height, exempt from the interference of external electromagnetic ripple, can suppress intrasystem signal to extraradial radio frequency three coaxial connector.

The technical solution used in the present invention is: a kind of radio frequency three coaxial connector, comprise plug and socket, the interface of plug and socket is made of outer conductor, middle conductor, three coaxial conductors of inner wire respectively, between three coaxial conductors by the insulator mutually insulated, outer conductor is transmission signals not, the shielding external disturbance.

Three coaxial conductor afterbodys of described socket connect three coaxial conductors and form double nip formula three coaxial sockets, perhaps welding of the terminals of three of socket coaxial conductor afterbodys or attaching cable; The terminals welding or the attaching cable of described plug.

Described socket and plug interface is three bayonet sockets or screw thread or push-in type connected mode.

The plug and socket interface section of this radio frequency three coaxial connector is made up of inner wire, middle conductor, the outer conductor of mutually insulated; outer conductor is transmission signals not; guard signal exempts from external interference; and can suppress intrasystem signal to external radiation; its shielding properties exceeds 40～50dB than non-shielded connector; improved the transmittability and the antijamming capability of data transmission system, compared, better shielding properties has been arranged with general shielded connector.Adopt three bayonet sockets or screw thread or push-in type connected mode between the socket and plug, easy to connect, reliable lock, electric property is stable, but fast insert-pull has good electrical properties, mechanical performance.This radio frequency three coaxial connector is applicable in the loop of rf of wireless device and electronic instrument, connects soft symmetrical radio frequency cable, triaxial cable, is specially adapted to require the radio frequency applications occasion of high shielding properties.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is further described.

As shown in Figure 1, inner wire 2, outer conductor 6 in the socket are an integral body, and middle conductor 4 is that two parts are integrally welded when assembling, and three coaxial conductors are formed double nip formula three coaxial connector respectively by

interior insulator

3,10 and 5,12 insulation of middle insulator.

Interior insulator

3,10 is installed on the inner wire 2 from two ends, the left and right sides respectively, on the

insulator

3,10, is welded as a whole then in two parts of middle conductor 4 also are installed in respectively, and

insulator

5,12 in putting is fixed with pressure ring 11, puts outer conductor 6 at last.Installing hole with socket slave unit panel during use passes, and from the another side of panel sealing ring 9, bullet pad 8 is installed then, at last with nut 7 lockings.

As shown in Figure 2, the inner wire 13 in the plug, middle conductor 15 and 17 of outer conductors are insulated by interior insulator 14 and middle insulator 16 respectively, form the tip side of connector plug, the other end attaching cable of plug.During use, the interface end of plug plugs together the interface end in socket, and rotation is installed in the card cap 18 on the outer conductor 17 then, makes the helicla flute 19 of pin 1 on the card cap on the socket rotate to spiral groove end locking.

The connected mode of socket and cable has interface formula, installation type, three kinds of forms of welded type:

1, Figure 1 shows that double nip formula three coaxial connector socket, when being connected with cable, need only the left end interface that the plug of cable link is inserted this socket, the card cap on the rotatable cable plug is locked then.

2, Figure 3 shows that and cable installation type socket, its right-hand member interface structure is identical with double nip formula socket shown in Figure 1, and its left end and cable connected mode adopt installation type, the inner wire of cable, middle conductor are connected with the tail end of socket inner wire 2, middle conductor 4 respectively, the shielding netting wire of cable places on the taper sheath 20, load onto line ball cover 21 after, line ball nut 22 is screwed in outer conductors 6 left end inner chambers, compress shielding netting wire, outer conductor and the conducting of cable shield netting twine.Connector plug left end shown in Figure 2 also is to adopt this kind crimping form with being connected of cable.

3, Figure 4 shows that and cable welded type socket, its right-hand member interface structure is identical with double nip formula three coaxial connector shown in Figure 1, and its left end and cable connected mode adopt welded type, the inner wire of cable, middle conductor weld mutually with the left end of socket inner wire 2, middle conductor 4 respectively, the shielding netting wire of cable then be welded on outer conductor 6 contacted weld tabs 23 on.
