Abstract
The utility model provides a kind of new SMA types jack to jack adapter adapter, including by part inner wire, outer conductor, insulating supporting.Insulator in this programme, embedding hole is not had to beat on outer conductor, also without annular groove is driven on inner wire, assembling is also fairly simple, finally only needs that outer conductor one, outer conductor two are screwed and tightened, the encapsulating process for eliminate complicated and more difficult operation, controlling.Most importantly advantage is the electrical property that this structure for not opening embedding hole greatly improves product, mainly solves SMA type jack to jack adapter adapters because the presence in embedding hole causes adapter hydraulic performance decline and the big problem of radio frequency leakage change occur in high band (18~26.5GHz).
Description
Technical field
It the utility model is related to a kind of new SMA types jack to jack adapter adapter.
Background technology
Existing SMA types jack to jack adapter adaptor structure is relatively simple, is generally made up of inner and outer conductor, insulating supporting, in order to protect
The axial restraint performance of card inner and outer conductor reaches 26.7N strength, it is necessary to drive an annular groove among inner wire, while right
The insulating supporting and outer conductor position answered open two embedding holes, it is necessary to which the tapping from outer conductor is inside after the completion of Product Assembly
The epoxy resin embedding adhesive of special proportioning is injected, and needs the Ageing Treatment of more than 48 hours, can be only achieved enough
Intensity, ensure the fixation of inner and outer conductor and insulating supporting, simultaneously because the appearance of embedding hole and annular groove result in the property of product
Energy.
The major defect of prior art mainly have it is following some：1st, due to the annular groove of inner wire, insulating supporting, with leading outside
Body embedding hole appears in same position, which results in the discontinuous of this section of impedance, microwave reflection increase, and product is used in 18~
Performance substantially reduces during 26.5GHz；2nd, complex operation, injecting glue process need the operation of skilled operation；It is although the 3rd, existing
There is the embedding hole that technique injecting glue is filled with outer conductor, insulating supporting, but due to epoxy resin and metal ingredient be present, therefore have
Radio-frequency leakage produces, for that can not be used under the higher environment of some electromagnetic shielding requirements；4th, epoxide-resin glue is matching
Easily it is affected by the external environment with potting process, for example, temperature, humidity, cleanliness factor, the easy band when a certain condition changes
Carry out some bad consequences, for example insulaion resistance, dielectric strength be not up to standard, severe patient even can cause inner and outer conductor stationarity
Do not reach standard, directly contribute product rejection.
This patent mainly solves SMA type jack to jack adapter adapters because the presence in embedding hole causes adapter in high band (18
~26.5GHz) there is hydraulic performance decline and the big problem of radio frequency leakage change.
Utility model content
