Abstract
The invention relates to improved radio frequency coaxial connector inner conductor. The improved radio frequency coaxial connector inner conductor is good in electrical characteristic and plugging and plucking performance, and long in service life. The improved radio frequency coaxial connector inner conductor comprises a pin-plugging portion and an in-plugging portion. The pin-plugging portion is provided with a hollow round cavity. The pin-plugging portion and the in-plugging portion are integrated, wherein three vertical grooves are evenly placed in an axial direction of the in-plugging portion. Each plugging and plucking groove is of three-point contact instead of original two-point contact, and therefore the electrical characteristics are improved by more than 30%, and plugging and plucking strength and bearing capacity are greatly increased. The improved radio frequency coaxial connector inner conductor can be plugged and plucked for more than 100 times, and can bear 100-200g, and therefore service life is greatly prolonged and cost is saved.
Description
Technical field
The present invention relates to the communications field, relate 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 transmission line electrical connection or the element that separates, is the important component part of electric connector, at present to standardization, and seriation, generalization future development.
The making material of existing radio frequency (RF) coaxial connector inner wire is phosphor-copper in the market, is comprised of contact pin section 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, and low, the poor flexibility of contact engaging and separating force is yielding after the plug repeatedly.
Summary of the invention
Technical problem to be solved by this invention is to provide for 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, technical scheme of the present invention is:
A kind of radio frequency (RF) coaxial connector inner wire of improvement, comprise contact pin section 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 greatly increased electrical characteristics, contact engaging and separating force and weight capacity, 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 greatly increased electrical characteristics.
Beneficial effect of the present invention is:
1. the plug groove increases to 3 contacts by 2 original contacts, and electrical characteristics have been increased more than 30%.
2. greatly increased contact engaging and separating force and weight capacity, 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 greatly increased electrical characteristics.

Fig. 2 is original radio frequency (RF) coaxial connector inner wire front view
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, the making material of existing radio frequency (RF) coaxial connector inner wire is phosphor-copper in the market, by Plug Division 11 and contact pin section extrusion molding about in the of 5, wherein, Plug Division 11 pinching ends 33 are provided with two guiding partss 22, and guiding parts 22 and dual-side 44 are one-body molded and become 135 ° of angles.The radio frequency (RF) coaxial connector inner wire electrical characteristics of this kind design are poor, and low, the poor flexibility of contact engaging and separating force is yielding after the plug repeatedly.
As shown in Figure 1, the radio frequency (RF) coaxial connector inner wire after a kind of improvement, its material changes beryllium copper into by phosphor-copper, has greatly increased electrical characteristics; This inner wire comprises Plug Division 1 and contact pin section 5, and Plug Division 1 has the hollow cylindrical cavity, is used for patching inner wire, and wherein, the head of Plug Division 1 axially evenly mills out all suitable three cannelures 3 of the degree of depth and width along inner wire; And the internal diameter of the front end of Plug Division 1 is less than back end inside diameter.The plug groove increases to 3 contacts by 2 original contacts, and electrical characteristics have been increased more than 30%, has greatly increased contact engaging and separating force and weight capacity, can plug more than 100 times, and load-bearing 100-200g has increased useful life greatly, has saved cost.
Claims (2)
1. the radio frequency (RF) coaxial connector inner wire of an improvement comprises contact pin section and Plug Division, and the Plug Division has the hollow cylindrical cavity, it is characterized by, and described Plug Division front end axially is provided with three cannelures uniformly.
2. the radio frequency (RF) coaxial connector inner wire of a kind of improvement as claimed in claim 1 is characterized by, and the material of described inner wire changes beryllium copper into by phosphor-copper
