Description
Technical field
The present invention relates to technical field of electric connectors, specifically a kind of elasticity with radial and axial float function
Hollow out radio frequency (RF) coaxial connector, the connector has blindmate characteristic, has and provides radial and axial larger amount of floating when coordinating
Function, transimission power is larger and low cost.
Background technology
The interconnection of plate plate is one of main application of radio frequency (RF) coaxial connector, can be used for radio-frequency module and is interconnected with radio-frequency module,
Interconnection between circuit board and radio-frequency module.In electronic communication industry, in view of manufacturing cost is constantly reduced and connector uses use
Way is widened, in order to reduce the connection of device interior cable as far as possible, make full use of limited inner space, reduction machine volume, reduction
Manufacturing cost, raising assembling capacity, multicore and multi signal connector arise at the historic moment, and various unlike signal simultaneous transmissions promote electricity
The degree of modularity more and more higher of sub- communication products.It is that cannot observe multiple power supplys or signalling contact when connector is plugged together
Relative position, it is desirable to connector must have the performance of blindmate to realize the connection of power supply or signal.Connect in the market
The main product of device mostly uses hard blindmate connected mode, and which is higher to the component locations degree requirement in module, processing
Relatively costly, careless slightly, product does not just coordinate, and causes to scrap.Future is more and more high with the integration degree of product, should
Connected mode is no longer practical by what is become.Therefore, develop a kind of less demanding to mounting position degree, while radio-frequency performance can be met again
Connector just seem very necessary.Occurs plate plate floating blind plugging connector mostly three-body type in recent years, by intermediate connector
Position skew realizes that plate partitioned signal is transmitted, relatively costly, portable poor.
The content of the invention
A kind of there is radial and axial float function, less demanding to mounting position degree present invention aim to provide
The coaxial connector of radio-frequency performance can be met again simultaneously.
Realizing the concrete technical scheme of the object of the invention is：
A kind of elastic hollow out radio frequency (RF) coaxial connector with radial and axial float function, the connector include plug and
Socket, socket and plug grafting, feature is that plug is made up of pressure pipe, spring silk, inner sleeve and interior bar, and interior club head is " Ω "
Shape, inner sleeve is " H " shape, and pressure pipe is fixed in interior bar, and spring silk is several, and inner sleeve is inserted in the front end of spring silk after bending backward
It is interior, in interior bar insertion spring silk and inner sleeve, it is fixed in interior bar by pressure pipe；Wherein, the inner sleeve and interior club head set
Gap is connect and maintains, inner sleeve outer ring is provided with chamfering, it is ensured that spring silk head is close to inner sleeve wall.
The spring silk makes for elastic conducting material, with certain degree of hardness.
Have gap between the inner sleeve and interior bar, inner sleeve can 360 ° freely swing.Inner sleeve realizes nothing when rotating
Hinder to swing, make connector that there is radial direction with axially larger amount of floating.
Beneficial effects of the present invention：
The present invention is used for the plate of electronic communication equipment and device to plate occasion, and elastic openwork part is provided in use
Radial and axial larger amount of floating, it is ensured that connector contact is good, and provides reliable and stable docking, and the hollow out cavity of formation is
High impedance transmission is provided in signals transmission, for radio frequency connector impedance matching provides high resistant optimization, is improved signal and is passed
Transmission quality.The present invention can be high-power connector, can be used for the diversified forms such as PCB transmission, cable transmission and distinct interface switching.
The present invention is double-body bike, and relative to three-body type floating blind plugging connector, amount of floating is big, docks outside functional, and simple structure is easy
OK, it is cost-effective.

Specific embodiment
Refering to Fig. 1, the present invention is made up of plug 1 and socket 2.Socket 2 and the grafting of plug 1；The head of plug 1 is provided with several springs
Silk 11, spring silk 11 front end bend backward after insert inner sleeve 12 in, interior bar 13 insertion spring silk 11 with inner sleeve 12 in, by pressure pipe
10 are fixed in interior bar 13.12 outer ring chamfering of inner sleeve 121 ensures that spring 11 heads of silk are close to the wall of inner sleeve 12, and spring silk 11 is in inner sleeve
Circumferentially type is uniformly distributed cylinder 12, it is ensured that be oriented to when plug 1 is docked with socket 2 good.Spring silk 11 is elastic conducting material, is had
Certain degree of hardness, docks with certain amount of contraction, it is ensured that contact is good, and signal transmission reliability is high with socket 2.Inner sleeve 12 with
There is certain interval between interior bar 13, when plug 1 is docked with socket 2, due to reasons such as processing, installation accuracies, it will usually there is center
Offset, misalign phenomenon, freely swung by 360 ° of inner sleeve 12, plug 1 can be inserted smoothly in socket 2.Interior bar 13
Portion is " Ω " shape, and inner sleeve 12 realizes without hindrance swing when rotating, and connector is had radial direction with axially larger amount of floating.
Interior bar 13 and spring silk 11 between be air dielectric, in signals transmission be one section of high impedance, compensate for automatically by
Diminish the discontinuity capacitance that causes in the impedance that brings of contact, by appropriate optimization, realize that impedance matching is good, reduce signal and pass
Defeated distortion rate.
The present invention can set the thickness of spring silk 11 according to connector using the height of power, and spring silk 11 is relatively thick, for height
Power connector, can plant for diversified forms such as PCB transmission, cable transmission and distinct interface switchings.Relatively with common three-body type
Plate connector for substrate, the present invention is simple and reliable for structure, and cost is relatively low, and excellent electrical properties.
Refering to Fig. 2, it is assumed that the theoretical distance between plate and plate is H.In actually used, plug 1 is placed in installing plate with socket 2
3 ends, when plug 1 is inserted to socket 2, if plate is not aligned with plate, then the taper face 21 of socket 2 can guide plug 1 smoothly to insert
Enter in socket 2, due to the elastic reaction and the automatic swing of inner sleeve 12 of spring silk 11, plug 1 is inclined one relative to socket 2
Determine angle, used without influence product, so as to eliminate damage of product that traditional hard blindmate connected mode causes and bad, realize
Radial floating.Due to the presence of the upper tolerance of manufacture, distance between plates is probably（H±a）, now, the elasticity work of the spring silk 11 of plug 1
With alloing it along the inwall slide anteroposterior of socket 2 apart from 2a, while ensureing that its contact is reliable, performance requirement is met, from
And realize axial floating.
