Abstract
The utility model relates to an improved radio frequency coaxial connector inner conductor which is good in electrical characteristic, excellent in plugging and pulling performance, and long in service life. The improved radio frequency coaxial connector inner conductor comprises a pin-plugging part and a connecting and plugging part. The pin-plugging part is provided with a hollow round cavity. The pin-plugging part and the connecting and plugging part are integrated, wherein the connecting and plugging part is provided with three vertical grooves which are evenly arranged in the axial direction of the connecting and plugging part. Plugging and pulling grooves are characterized by three-point contact instead of original two-point contact, and therefore electrical characteristics are improved by more than 30%, and plugging and pulling force and bearing capacity are greatly increased. The improved radio frequency coaxial connector inner conductor which can be plugged and pulled for more than 100 times is characterized by 100-200g bearing capacity, greatly prolonged service life and saved cost.
Description
Technical field
The utility model relates to the communications field, relates in particular to a kind of radio frequency (RF) coaxial connector inner wire.
Background technology
Radio frequency (RF) coaxial connector is to be installed on the cable or to be installed in a kind of element on the instrument, as the element that transmission line is electrically connected or separates, is the important component part of electric connector, at present to standardization, and seriation, the generalization direction develops.
The making material of existing radio frequency (RF) coaxial connector inner wire is phosphor-copper in the market, is made up of contact pin portion and Plug Division, and wherein, the Plug Division pinching end is provided with two guiding partss, and guiding parts is one-body molded with dual-side and become 135 ° of angles.The radio frequency (RF) coaxial connector inner wire electrical characteristics of this kind design are poor, low, the poor flexibility of contact engaging and separating force, and plug repeatedly back is yielding.
The utility model content
Technical problem to be solved in the utility model is to provide at above drawback that a kind of electrical characteristics are good, plug property is good, the radio frequency (RF) coaxial connector inner wire of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of radio frequency (RF) coaxial connector inner wire of improvement, comprise contact pin portion and Plug Division, the Plug Division has the hollow cylindrical cavity, wherein, described Plug Division front end axially is provided with three cannelures uniformly, has increased electrical characteristics, contact engaging and separating force and weight capacity greatly, can plug more than 100 times, load-bearing 100-200g has increased useful life greatly, has saved cost.
The radio frequency (RF) coaxial connector inner wire of above-mentioned improvement, wherein, the material of described inner wire changes beryllium copper into by phosphor-copper, has increased electrical characteristics greatly.
The beneficial effects of the utility model are:
1. the plug groove increases to 3 contacts by 2 original contacts, and electrical characteristics have been increased more than 30%.
2. increased contact engaging and separating force and weight capacity greatly, can plug more than 100 times, load-bearing 100-200g has increased useful life greatly, has saved cost.
3. the material of inner wire changes beryllium copper into by phosphor-copper, has increased electrical characteristics greatly.
Description of drawings
