Yet the said goods but exists following problem and defective:
1, the cylindrical body of the external conductor processing back of curling does not add fixingly again, relies on medium to limit it fully and keeps circle, for this small sized product, the medium diapire is very thin, in the product use, is easy to produce drawing deformation, thereby cause gap, 51 place, junction to become big, the destruction of scattering.
2, this small sized product drawing dynamics in use is difficult to control, after being welded on the circuit substrate, during drawing, the weld part 52 of external conductor and circuit substrate is in stress point and stress concentration point, cause easily pull the weldering in addition material tear, make product breaking circuit substrate.
3, be right angle (wedge angle) structure 53 entirely outside the leg position that product combines with circuit substrate, in transmission signal process, be easy to cause point discharge, cause external circuit is disturbed.Horn structure also causes the staff to scratch easily.
4, normal structure or other similar structures that adopts 54 places of the axial restraint of center conductor and medium, for this small internal conductor, difficulty of processing is too big.
The utility model content
The purpose of this utility model is to provide a kind of radio-frequency (RF) coaxial electric connector, the cylindrical body that mainly solves the existing product external conductor is scattered in using easily, the weld part of external conductor and circuit substrate pulls easily, technical problems such as point discharge are caused at the leg position that product combines with circuit substrate easily, it can improve the reliability of external conductor, improve the adhesive force of external conductor and circuit substrate, the prevention point discharge, minimizing is disturbed external circuit, improves medium to the confining force of center conductor and prevent ability and the convenient processing that fusion scolding tin adheres to.
For realizing above-mentioned utility model purpose, the technical solution of the utility model is:
A kind of radio-frequency (RF) coaxial electric connector, it comprises the external conductor with cylindrical portion and leg, the center conductor of the contact site that extends towards axial direction in the inner space of cylindrical portion, and make external conductor and center conductor conductor bottom molding connect into the medium of type; It is characterized in that: the joint portion of described external conductor cylindrical portion has tenon type interface.
Described radio-frequency (RF) coaxial electric connector is characterized in that: the leg of described external conductor has bilateral circular arc type groove.
Described radio-frequency (RF) coaxial electric connector is characterized in that: described center conductor bottom has extension below medium and towards the radial direction portion of radial direction outside curve; Bottom surface in this radial direction portion forms the leg that contacts with circuit substrate; Center conductor with contact-making surface that medium contacts on have the Ministry of worker that adds through being processed into tenon shape, add the Ministry of worker and engage with medium.
Described radio-frequency (RF) coaxial electric connector is characterized in that: described center conductor and external conductor and the outside, circuit substrate contact site all have arc end.
Compared with prior art, the beneficial effects of the utility model are:
1, the joint portion of external conductor cylindrical portion has tenon type interface in the utility model product, and it can improve the reliability of external conductor, in product plug process, guarantees the integrality of external conductor, and is not yielding.
2, the leg of external conductor has bilateral circular arc type groove in the utility model product, it can effectively make this connector in product plug process between cylindrical portion and weld part the stress point of active force transfer to the centre position from the marginal position of weld part, improve the adhesive force of soldering, be difficult for pulling, be difficult for tearing; Prevent that fusion scolding tin from adhering to; Increase the contact area of dielectric and external conductor, increase adhesion.
3, center conductor and external conductor and the circuit substrate contact site outside all has arc end in the utility model product, and it can prevent the product point discharge, reduces the interference to external circuit, and can improve the fail safe in the production process.
4, the center conductor bottom has extension below medium and towards the radial direction portion of radial direction outside curve in the utility model product; Bottom surface in this radial direction portion forms the leg that contacts with circuit substrate; Center conductor with contact-making surface that medium contacts on have the Ministry of worker that adds through being processed into tenon shape, adding the Ministry of worker engages with medium, this structure processing simply can reach the confining force that improves medium and center conductor again equally, even the external force of bearing, center conductor is difficult drop-off also, even simultaneously welding is heated, can not form the gap owing to thermal expansion and between medium yet, can effectively avoid fusion scolding tin etc. to enter the effect in gap.
