Description
Technical field
The present invention relates to the radio frequency connector of field of wireless communication, especially relate to a kind of low intermodulation and insert the radio frequency connector and method of operation thereof that are connected with screw thread compatibility soon.
Background technology
Radio frequency connector is important connection in microwave transmission system and disjunction components and parts, and the radio circuit form connected mainly contains between the inner each functional module of Wireless Telecom Equipment, between antenna and receipts transmitter module, between various radio frequency coaxial-cable, the connection of microstrip circuit and printed circuit etc.; The main application market of radio frequency connector has the fields such as Wireless Telecom Equipment, vehicle electronics, medicine equipment, Aero-Space and military navigation.The function of radio frequency connector and performance index require: can connect with except breaking function except possessing, also must meet electric property, mechanical performance under its connection status, and the requirement of environmental resistance.Specifically, radio frequency connector will transmit radio frequency electromagnetic signal and energy effectively, and its characteristic impedance must match with the characteristic impedance of be connected radio system; Moreover along with the fast development of global communication cause and the continuous advancement of science and technology, the electric property such as intermodulation index, return loss, shield effectiveness of radio frequency connector itself proposes new requirements at the higher level.
Based on function and the requirement of above-mentioned radio frequency connector, connected mode of the prior art and version varied.Separate design (namely mechanical reference surface does not overlap with electrical reference face), in order to meet the connection request under different condition and environment, has been made in mechanical reference surface and electrical reference face by the radio frequency connector of prior art; Meanwhile, socket outer conductor contact head or plug outer conductor contact head are done the design of slotting; To realize the contacts side surfaces between outer conductor, make signal code by side conducting.
Such as: the international standard issued in 1976: IEC60169-13 " radio frequency connector the 13rd part: outer conductor internal diameter is 5.6mm, characteristic impedance is 75 Ω (1.6/5.6 type) and 50 Ω (1.8/5.6 type), there is the less radio frequency connector plugging together size ", made separate design to mechanical electric datum level, namely mechanical reference surface does not overlap with electrical reference face; Meanwhile, the design of slotting has been done to plug outer conductor contact head, has referred to this international standard original text Fig. 1, Fig. 2.Its special benefits of above-mentioned design, has done the statement that both pictures and texts are excellent in the standard, refers to this international standard original text Fig. 3, Fig. 4, Fig. 5; Namely this structure can adapt to the realization of multiple locking mechanism or connected mode, comprises fast slotting mode; But the defect of this structure have lost upper limit radio frequency bandwidth, also design is not made to concrete Kuai Cha mechanism.
Again such as: the international standard issued in 1975: IEC60169-4 " radio frequency connector the 4th part: outer conductor internal diameter is 16mm, characteristic impedance is 50 Ω, the radio frequency (RF) coaxial connector (7-16 type) that is threaded ", mechanical electric datum level does not do the design be separated, but arbitrary design of slotting or do not slot has been done to socket outer conductor contact head, and require that its contact head of design of fluting should meet contact performance requirement, refer to this international standard original text Fig. 2.But the defect of this structure is structure is only adapted to the locking mechanism mode that is threaded, can not adapt to the requirement of fast inserting structure design.
Again such as: what take in the fast inserting structure of prior art connector be cross section is leg-of-mutton jump ring (springy locking member), it is axial lock face by a right-angle side in triangle, and another right-angle side is for radially sliding face; And the inclined-plane in triangle is for separating locking face; Though but this structure only local environment application but defect be insert with unlock unhappy; Meanwhile, this structure must contain due to three square rings and require that the shell body of locking plug can meet the reliability under vibration environment; But consequently insecure through realistic simulation test, namely three square rings only rely on natural resiliency to be difficult to lock plug outer housing, and therefore its applied environment of this syndeton has larger circumscribed defect.
In sum, some the concrete defects in prior art products and not enough main manifestations as follows:
1) the intermodulation index that mobile communication is important and return loss index not yet arrive the requirement of modern complete machine communication equipment good level;
2) due to outer conductor contacts side surfaces, and Summerside accepts, the existence of outer conductor end play, causes and reduces due radio frequency bandwidth;
3) insert and unlock unhappy, can not adapt to have the application under larger vibration environment;
4) plug of same specification or close specification can not compatible be connected with socket;
5) fast-insertion self-locking mechanism needs corresponding draw-in groove, and due to the existence of manufacturing tolerance, unavoidably leaves gap when inserting; Namely having caused shelves locking, is also the main cause causing axial endplay or come off;
6) because contact head needs split to design and process and assembling, cause manufacturing cost to raise, the accuracy of manufacture is also affected.
