Abstract
The utility model discloses a SMA connector, including the shell, set up in insulator in the shell, set up in contact pin in the insulator, and the cover is located snap ring on the shell, swivel nut, be equipped with on the shell and be used for the installation the snap ring groove of snap ring, be equipped with the buffering step on the snap ring groove. The utility model has the advantages that change the structure of shell snap ring groove department, made the snap ring have buffer space, not only improved the fastness of swivel nut, still stopped the phenomenon that the swivel nut breaks away from, effectively ensured connector normal use, improved the quality of product greatly.
Description
Technical field
This utility model relates to a kind of radio frequency connector, specifically a kind of SMA type adapter.
Background technology
SMA adapter is a kind of widely used small-sized threaded coaxial connector.SMA adapter is applicable to the application of the microwave regime of the straight 26.5GHz of frequency range.It has, and bandwidth, performance be excellent, highly reliable, the feature of life-span length, and range of application is relatively wide, such as telecom communication, network, wireless telecommunications, detection, measurement instrument.
But existing SMA adapter, it docks with SMA-K head when screwing, and swivel nut easily comes off, and affects the normal use of adapter.
Utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model is to provide a kind of adapter, and when screwing for solving to dock with SMA-K head, swivel nut holds caducous problem.
Technical scheme: a kind of SMA adapter, including shell, is arranged at the insulator in described shell, it is arranged at the contact pin in described insulator, and it being sheathed on the snap ring on described shell, swivel nut, described shell is provided with the annular groove for installing described snap ring, and described annular groove is provided with buffering step.
Further, for ensureing the air-tightness of adapter, shell is also equipped with seal washer.
Further, for ensureing the mechanicalness of adapter, shell is coated with ternary alloy three-partalloy.
Beneficial effect: compared with prior art, the utility model has the advantages that the structure that have changed shell annular groove place, makes snap ring have cushion space, not only increase the fastness of swivel nut, also having stopped the phenomenon that swivel nut departs from, effective guarantee adapter normally uses, and substantially increases the quality of product.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the structural representation of shell；
Fig. 3 be in Fig. 2 A to partial view.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is all fallen within the application claims limited range by those skilled in the art.
As it is shown in figure 1, a kind of SMA adapter, including shell 1, insulator 2, contact pin 3, snap ring 4, swivel nut 5, seal washer 8.Insulator 2 is arranged in shell 1, and contact pin 3 is arranged in insulator 2.Snap ring 4, seal washer 8 and swivel nut 5 are installed on shell 1.As Figure 2-3, snap ring 4 is installed in the annular groove 6 of shell 1.The junction of annular groove 6 and shell 1 is provided with a taper buffering step 7.Buffering step 7 setting, make snap ring 4 have certain cushion space, adapter dock with SMA-K head screw time, snap ring has had certain cushion effect, has stopped the phenomenon that swivel nut 5 comes off.Shell 1 is coated with ternary alloy three-partalloy, further increases the mechanical performance of adapter, more firmly, reliably.
During assembling, being pressed in shell 1 by insulator 2, then be installed in annular groove 6 by snap ring 4, seal washer 8 is also mounted on shell 1, then swivel nut 5 is loaded on shell 1, finally inserts in insulator 2 by contact pin 3,.
