Description

A kind of radio frequency connector

Technical field

The utility model relates to electric connector field, is specifically related to a kind of radio frequency connector.

Background technology

The application requirement day by day promoted along with the field such as electronics, communication, radio frequency contact right electrical property and frequency requirement more and more higher.Traditional radio frequency connector frequency band is narrow, and performance is general, makes troubles, often needs integral replacing during updating apparatus, cause the wasting of resources to the expansion of equipment and optimization.

Utility model content

Utility model object: for problems of the prior art with not enough, provide a kind of radio frequency connector, can solve frequency issues, has reliable electrical property simultaneously and connects.

Technical scheme: a kind of radio frequency connector, comprise corresponding socket and plug, when mutually plugging together, the outside end face of described plug casing fully contacts with between the hole end surface of described Socket casing, simultaneously, the maintenance gap, outer face of the hole inner face of described plug casing and the outer resilient contact of described socket, this structure forms good electric property.

Preferably, the hole end surface of described Socket casing is 8.5 ± 0.10mm to the degree of depth of bottom, and the hole end surface of described plug casing is 8.3 ± 0.10mm to the distance of outside end face, and this size can form effective interstitial structure after plugging together.

Preferably, the described socket plugged together for a pair and the inner conductor outer diameter of plug are 2.1 ± 0.10mm, and outer conductor internal diameter is 4.9 ± 0.10mm, and the connecting thread that socket and plug plug together is M12x1.

Further, the outer resilient contact of described socket is six grooves or the contact of eight grooves, and notch, by least two cambered surface rounding ofves, can ensure to coordinate smooth and easy time slotting with plug, ensures electric continuity and excellent electrical property simultaneously.

Further, the contact head of described outer resilient contact is step, and front end and middle part form two-stage step, to improve its mechanical strength and useful life.

Further, the inner wire resilient contact of described socket is three groove contacts, and the inner wire termination of described plug is that semicircle is spherical, better plugs together from mechanical angle, promotes plug number of times, reduces friction, in the improving product life-span, have more excellent electrical property.

Further, the hole end surface chamfering of described plug casing is 10 ~ 12 °, and the hole end surface chamfering of described Socket casing is 15 ~ 25 °, and two end faces, all by arc angle rounding off, ensure that product is smooth and easy gently when mutually plugging together.

Further, the housing of described plug can set up sealing ring or sealing gasket according to different needs, improves the classification of waterproof of product.

Beneficial effect: 1, can to overcome the electrical property of former radio frequency connector not enough for the utility model, and cut-off frequency can reach 27GHz, and have fast insert-pull, connect reliable characteristic, there is good voltage standing wave(VSW) when intermodulation index, resistance to power;

2, the utility model outer conductor adopts and is threaded, and is equipped with outer resilient contact, makes product can fast insert-pull; In addition, owing to adopting outer Elastic Contact, with the coordinating of plug, make the signal of telecommunication be in continuous situation always, therefore ensure that the electrical performance indexes of product is stronger;

3, outer resilient contact is designed to 6 groove ~ 8 grooves, significantly improves the useful life of product, by the design of this structure, makes rise at least 1000 times the mechanical endurance of product, and still have excellent electrical property after repeatedly plugging together;

4, inner wire adopts 3 groove designs, has and well plugs together characteristic, guarantee that product plugs together and more excellent electrical property.
