Description

A kind of millimeter wave connector insulator assembly that is suitable for highly-efficient processing

One, technical field:

The utility model relates to a kind of millimeter wave connector, especially relates to a kind of millimeter wave connector insulator assembly that is suitable for highly-efficient processing.

Two, background technology:

Radio frequency (RF) coaxial connector is widely used in every field such as microwave communication project, military project weapon and space flight and aviation system, has advantages such as easy to connect, easy maintenance.Connector more and more trends towards aspect development such as miniaturization, high-frequency simultaneously.

Millimeter wave connector typically refers to the connector of operation wavelength below 10mm, is a kind of Subminiature microwave coaxial connector.Its feature is the operating frequency height, physical dimension is little, required precision is high.Be widely used in aspects such as satellite communication, system testing.

Having released the millimeter wave connector kind at present in the world has: millimeter wave connectors such as 1.9mm, 3.5 series, 2.92 series (K type), 2.4 series, 1.85 series, 1.0 series.Wherein, though 1.9mm connector frequency can arrive more than the 50GHz, because of poor reliability fails to apply.The millimeter wave coaxial connector with excellent electrical properties of the practicality that 3.5 series is the mid-1970s to be released the earliest by U.S. HP and Amphenol company, obtained using widely, but because its 8mm whole frequency of can not working, and the manufacturing cost costliness, thereby limited the extensive use of this connector and further developed.Nineteen eighty-three, the William.Old.Field senior engineer of Wiltron company develops a kind of novel K type (2.9 series) connector.It can use in the DC-40GHz frequency band range, has good electrical properties, and can with widely used SMA connector compatibility now, be one of millimeter wave joint that is most widely used in the world at present.Almost meanwhile, some experts of U.S. Hewlett-Packard Corporation newly develop 2.4 serial millimeter wave connectors.

The millimeter wave connector volume is little, precision is high, the very difficult control of part processing difficulty height, insulator sizes, so most of manufacturer does not have to reach the batch process of millimeter wave connector.Because the millimeter wave product structure is special, mostly at present a lot of insulators and inner wire are the structure as Fig. 1 and Fig. 2.The at present most car system of millimeter wave insulator machines individual, also have indivedual producers to adopt injection mo(u)lding processing, but production efficiency is not high, and qualification rate is also very low, and the insulator versatility is very poor.After insulator processes with slit of insulator cutting, then by the slit inner wire of packing into, usually also can be at lining of insulator overcoat, be used for guaranteeing that inner wire and insulator combine closely, as Fig. 3.

Three, utility model content:

The utility model is in order to solve the weak point in the above-mentioned background technology, a kind of millimeter wave connector insulator assembly that is suitable for highly-efficient processing is provided, it can both can guarantee millimeter wave connector high-performance, high-frequency requirement, satisfies the product lot quantity production requirement again simultaneously.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of millimeter wave connector insulator assembly that is suitable for highly-efficient processing comprises inner wire, and inner wire is arranged on the insulator, and lining is arranged on exterior insulator.

The endoporus of above-mentioned lining can be a unthreaded hole.

The endoporus of above-mentioned lining can have step or hangnail.

The groove of above-mentioned inner wire can have step or hangnail.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, structure of the present utility model makes it can adopt the processing of millimeter wave insulator insert molding, and it has inherited the advantage of plastic shaping, is beneficial to batch process, has improved the working (machining) efficiency of millimeter wave product insulator greatly.

2, the millimeter wave insulator processing method of the utility model employing has very strong versatility.The strictness of millimeter wave connector dimensional requirement, small size all can influence its electric, mechanical performance.The processing method that the utility model provides can adjust the millimeter wave connector performance by hole dimension in change inner wire size, the lining, and everything need not be changed mould, does not influence the processing and forming operation.This has not only improved life cycle of the product, and can lack the die sinking tool, reduces cost.Lining can remove after moulding is finished, and can effectively reduce the size of insulator assembly.

3, accessory size guarantees easily, can improve the millimeter wave connector electric property.Adopt millimeter wave insulator processing method, as long as die size is stable, accessory size stability is easy to guarantee, can utilize simultaneously the advantage of moulding, produce comparatively complicated insulator structure, can effectively reduce the insulator effective dielectric constant, can improve the millimeter wave connector electric property.
