Abstract

The utility model relates to a coaxial radio frequency electric connector with air medium. The coaxial radio frequency electric connector comprises a plug case, an internal conductor and an internal conductor bracket. The internal conductor bracket is cross-shaped, the internal conductor is cast on the cross-shaped bracket, the bracket is fixed at the contact point between the bracket and the case by a bracket groove, and PPO material is adopted for the cross-shaped bracket. The coaxial radio frequency electric connector adopts a novel material, the structure is unique, the performance is stable and reliable, and the standing wave wiht the electrical property of the coaxial connector is ensured not to be larger than 1.2 in a very wide frequency range, namely, DC-40 GHz, and the requirements on high frequency application can be realized.

Description

A kind of coaxial radio-frequency electric connector of air dielectric

Technical field

The utility model relates to the radio frequency electric connector, and relating in particular to the air is the coaxial radio-frequency electric connector of medium.

Background technology

Coaxial electric coupler is widely used in technical fields such as microwave communication, space flight navigation, armament systems and microwave measuring equipment, has that volume is little, a bandwidth, mechanical electric superior performance, and the reliability advantages of higher is widely used.But the frequency of utilization of coaxial electric coupler is in DC～12.4GHz scope for a long time, standing wave can accomplish≤and 1.2, surpass 12.4GHz, because the dielectric constant problem of dielectric, causing standing wave and inserting loss all has rapid increase, can not use.The high frequency use problem of coaxial connector never is well solved.Way in the reality is screening at present, from batch, screen by test, and such waste of manpower as a result and material resources, and be difficult for guaranteeing.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of coaxial radio-frequency electric connector of air dielectric is provided, this connector construction uniqueness, and stable performance, reliable can realize the demand that high frequency uses.

The technical scheme that realizes the utility model purpose is: a kind of coaxial radio-frequency electric connector of air dielectric, comprise plug casing, inner wire, inner wire support, and described inner wire support is cross; The inner wire casting is on cross support; At the contact point of support and housing, support is fixed with bracket groove; Cross support adopts the PPO material, in the bottom design of inner wire dustproof gasket is arranged.

The characteristics that the utility model compared with prior art has are: the inner wire support adopts dielectric constant to approximate 1 high-low temperature resistant, high-intensity rigidity PPO material through Mould Machining and inner wire casting together, has guaranteed concentricity.Support is cross, and air is negotiable, has realized that the dielectric dielectric constant approximates 1, thus guarantee connector electrical property standing wave in frequency range DC～40GHz smaller or equal to 1.2.At the contact point of support and housing, realize the inner wire anti-rotation thereby there is bracket groove that support is fixed.

Embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of coaxial radio-frequency electric connector of air dielectric comprises plug casing 2, inner wire 1, inner wire support 3, and wherein inner wire support 3 is cross; Inner wire 1 casting is on cross support 3; At support 3 contact point, support is fixed with bracket groove 4 with housing 2; Cross support 3 adopts high-low temperature resistants, high-intensity rigidity PPO material, in the bottom design of inner wire 1 dustproof gasket 5 is arranged.

This connector has adopted novel PPO material, the structure uniqueness, and stable performance, reliable has guaranteed that coaxial connector electrical property standing wave in quite wide frequency range DC～40GHz realized the demand that high frequency uses smaller or equal to 1.2.
