Referring to Fig. 4, the coaxial terminal includes the coaxial cable 26 of two straight micro coaxle connectors 191 and arc, arc
The both ends of the coaxial cable of shape are connected with two straight micro coaxle jointings respectively.
Include straight micro coaxle jointing 191, right angle micro coaxle jointing referring to Fig. 5, or the coaxial terminal
192 and the coaxial cable 26 of straight form, the both ends of the coaxial cable of straight respectively with straight micro coaxle jointing and right angle
Micro coaxle jointing connects.
The electrical property of electric connector depends on all elements rather than some element.The peak frequency of coaxial line must be passed
The maximum useful frequency of most weak element in defeated line, for example, the frequency of use of some radio frequency connector is 10GHZ, with
The frequency of use for the cable that it is connected is 5GHZ, and the maximum useful frequency of this component is exactly 5GHZ.The synthesis of all factors is determined
The frequency of use of whole transmission line is determined.
When electric connector is applied on a printed circuit, when cable outlet direction needs to turn round downward, in inserting for closing
Coaxial cable transition is used in seat, what coaxial cable was selected is semi-rigid cable, and this semi-rigid cable can reach the use of 20GHZ
Frequency, has the advantages that frequency is high, decay is low, standing wave is small, advantages of good shielding performance, reliability height etc., hence it is evident that improve electric connector
Electrical property.
Referring to Fig. 2-Fig. 3, a guide groove 18, the guide groove are respectively provided with the upper bottom of the D types matching port
Protrude and positioned opposite, tilted toward the direction away from jack, angle of inclination r is more than 90 degree inside D types matching port.Insert
Head is equipped with trapezoidal inner sleeve, and an arc groove, the guide groove and the arc groove phase are respectively provided with bottom in trapezoidal inner sleeve
Coordinate.It can so realize the accurate positionin of socket and plug, ensure that can be inserted perpendicularly into and separate when socket and plug plug.This
When guide groove with arc groove be that line contacts, then when promoting and breakaway plug, frictional resistance diminishes, it is easier to operates.
D types insulation board 15 is equipped with the D types matching port, the D types insulation board is by between the multiple coaxial terminal
Insulation, and will insulate between the multiple coaxial terminal and the housing, D types insulation board can be rubber slab, resin plate etc.；
The multiple coaxial terminal further includes external terminal 20, inner terminal 14 and insulating part 17, and 14 He of inner terminal is equipped with the external terminal
Insulating part 17, is filled with insulating part between the external terminal and inner terminal, insulating part can use rubber ring, resin circle etc..
In the application, applicant has also done following design, and referring to Fig. 6-Fig. 7, the inner terminal is equipped with jack 12 and is oriented to
Hole 23, the pilot hole are conical bore, and the angle a of the conical bore is 90 degree；The design of inner terminal pilot hole, which is met, to be electrically connected
Guiding guide function during device interfix is connect, but is typically due to the thin damage for easily leading to product of wall, pilot hole is designed as conical bore,
Its angle a is designed as 90 degree, not only ensure that the wall thickness in hole, but also plays the role of guiding.If the wall of the inner terminal used is thin,
It is likely to that hole interior metal can be caused hereby to be broken in follow-up crimping, assembling, experiment and transportational process, metal is hereby broken
It is fewer when may have no effect on use, fracture it is more when conducting resistance will be caused the failure such as to become larger；
Since aperture wall is thin, also easily causes destruction to jack in plug, break down.Multiple inner terminals are made of copper product,
It is gold-plated in jack, ensure that contact pin and jack contact are good.The pilot hole is connected with the jack, is set on the multiple inner terminal
Have an axial grooving 24, in the vestibule of jack on have protrusion 25, the protrusion staggers vertically.Because inner terminal is equipped with axially
Grooving, makes jack play elastic deformation, and avoiding contact pin from being interference fitted with jack causes contact engaging and separating force excessive, therefore plugs soft, guarantee
Mechanical life of product；Protrusion 25 is had in the vestibule of jack, the protrusion staggers vertically, because of contact pin and raised structure
Into good retaining structure, it ensure that contact pin is tightly combined with jack, the reliability of docking.
The housing of the socket includes metal shell 33 and non-metal shell 31, and the metal shell is equipped with metal flange
11, the non-metal shell is connected with the metal flange, and the non-metal shell is equipped with two mounting holes 32.Non-metal case
Body uses resin embedding housing, reduces manufacturing cost.In the application, metal flange can be matched port with D types and set
One is calculated as, selects metal material to make；Electric connector can be fixed to by mounting hole on printed circuit board, goes out wire bonding
Solder joint on to printed circuit board will not be influenced and snapped by external force, all be risen during follow-up experiment, transport and use
The effect of protection solder joint is arrived.
Metal O-ring 21 is fixed with the metal flange.After plugs and sockets locking, pass through compressed metal O-ring, metal
O-ring deforms, and is adjacent to the mating surface of plugs and sockets, efficiently solves the jamproof problem of electric connector magnetic conduction.
The metal flange is equipped with the nut 16 of step, described to have the nut of step is interior to be equipped with threaded hole 22.Match somebody with somebody with it
The plug of set is equipped with bolt, and the bolt is closed with the corresponding threaded holes.Electric connector both ends are using thread fitting
Mode is locked, both convenient for assembly, also be can guarantee that and is reliably locked between plugs and sockets.
Referring to Fig. 8-Fig. 9, the socket is equipped with protective cover 28, and the protective cover cooperates with the socket；It is described
Protective cover is equipped with guide way 29 and trapezoidal overcoat 30, and the trapezoidal overcoat is engaged with D types matching port；The guiding
The end of body is cone 291, and the conical cone angle A is 90 degree.Due to the cone angle of the pilot hole of inner terminal
Also it is 90 degree, both cooperate, and play the role of sealing.When electric connector is non-working condition, protective case and socket phase
Mutually coordinate, play dust protection, prevent foreign matter from entering in the jack of socket；When inner terminal in use, if generated
Flexural deformation, since the cone angle of guide way is consistent with the cone angle of the pilot hole of inner terminal, by the guiding of guide way
The vertical of correction inner terminal can be played, ensures that the contact pin of plug is normally inserted into use.
Micro coaxle electric connector provided by the utility model, the guide groove matched by D types on port are accurately positioned so that
Socket and plug can be inserted perpendicularly into and separate when plugging, and so contact pin and jack will not be caused to be damaged, ensure that the use of product
Service life.In addition, the reliability that contact pin is connected with jack significantly improves, plug operation is easy.Therefore, which is electrically connected utensil
There is the characteristics of structure size is small, easy to install, connection reliability is high.
