Summary of the invention
Technical problem to be solved by the utility model is to provide one kind can save detection time, improves working efficiency
The plug-in adapter for radio frequency (RF) coaxial connector.
The utility model is used for the plug-in adapter of radio frequency (RF) coaxial connector, including outer housing, passes through inside outer housing
Insulator is equipped with inner conductor, is provided with reducing sleeve outside outer housing leading portion, it is characterised in that: reducing sleeve inner surface is provided with energy
Enough smooth stepped holes for outer housing cooperation grafting, outer housing leading portion wall portion is along the circumferential direction evenly arranged with a plurality of from front end face
The open slot longitudinally extended axially rearward, so that outer housing leading portion is configured to inside squeeze and reduces or expand outward opening
Flexible expansion nested structure, insulator extend to expansion sleeve structure inner chamber front end along shell intracoelomic cavity；
The outer housing middle section and reducing sleeve back segment inner surface are micro- interference fit, the micro- interference fit face in outer housing middle section with
There is one section of transition conical surface between limited step hole；
Position on the outer housing excircle by front end, which is provided with, swings to inclined-plane；
The outer housing leading portion wall is along the circumferential direction evenly arranged with six and longitudinally extends axially rearward from front end face
Open slot；
There is one section of annular knurl anti-slip section on the outer circumference surface of the reducing sleeve middle section；
It is provided with one section of toroidal cavity on external peripheral surface in the middle part of the inner conductor, outer housing is corresponding to toroidal cavity
Position is provided with handle hole.
The utility model is used for the plug-in adapter of radio frequency (RF) coaxial connector, and reducing sleeve passes through smooth stepped hole and shell
Body is quickly mating, and outer housing leading portion is arranged six vertical existing open slots and constitutes expansion nested structure, and expansion nested structure passes through elasticity

Detailed description of the invention
Fig. 1 is the plug-in adapter planar structure schematic diagram that the utility model embodiment is used for radio frequency (RF) coaxial connector.
Specific embodiment
As shown, a kind of plug-in adapter for radio frequency (RF) coaxial connector, including outer housing 5, inside outer housing 5
Inner conductor 6 is installed by insulator 12, reducing sleeve 1 is provided with outside 5 leading portion of outer housing, 1 inner surface of reducing sleeve is provided with energy
Enough smooth stepped holes for cooperating grafting for outer housing 5,5 leading portion wall portion of outer housing is along the circumferential direction evenly arranged with a plurality of from front end
The open slot 7 that face longitudinally extends axially rearward, so that outer housing leading portion is configured to inwardly squeeze diminution or outward expansion
The flexible expansion nested structure opened, insulator 12 extend to expansion sleeve structure inner chamber front end along 5 inner cavity of outer housing；Reducing sleeve
Quickly mating by smooth stepped hole and outer housing, expansion nested structure clasps insulator by elastic-restoring force clamping, even
It connects reliable, is connected without screw thread rotation, also can be quickly disassembled and exits after the completion of detection, detection process plug and pull, when consuming
Between it is few.
5 middle section of outer housing and reducing sleeve back segment inner surface are micro- interference fit, the micro- interference fit face 10 in 5 middle section of outer housing with
There is one section of transition conical surface 9 between limited step hole, since transition conical surface diameter is gradually increased when outer housing is inserted into reducing sleeve, insert
Termination process is easy to operate.
Position on outer housing excircle by front end, which is provided with, swings to inclined-plane 8, provides grafting guiding, positioning for outer housing
Accurately.
Outer housing leading portion wall is along the circumferential direction evenly arranged with six openings longitudinally extended axially rearward from front end face
Slot 7, expansion sleeve structure stress is uniform, and connection is reliable.
There is one section of annular knurl anti-slip section 2 on the outer circumference surface of reducing sleeve middle section, can prevent from skidding.
One section of toroidal cavity 11, outer housing and toroidal cavity corresponding positions are provided in the middle part of inner conductor on external peripheral surface
It installs and is equipped with handle hole 4, the packing material in toroidal cavity 11 is convenient for by handle hole 4, provides fixed limit for inner conductor.
The utility model is used for the plug-in adapter of radio frequency (RF) coaxial connector, and reducing sleeve passes through smooth stepped hole and shell
Body is quickly mating, and outer housing leading portion is arranged six vertical existing open slots and constitutes expansion nested structure, and expansion nested structure passes through elasticity
Insulator is clasped in restoring force clamping, and connection is reliable, is connected without screw thread rotation, also be can be quickly disassembled and is exited after the completion of detection,
Mass production detection time is shortened, is improved work efficiency, manpower, time input cost are reduced.
Specific technical solution:
1. product (SO) SMA-JK product belongs to the adapter in SMA series, improved by conventional screw-type connection connector
For quick plug-in connector
2. improved advantage is obvious, service efficiency can be greatly improved, when usage scenario is a large amount of test jobs, effectively
The shortening testing time, improve efficiency, cost of labor can be further decreased in very big program.
