The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 4 show a coaxial connector separation preventing structure according to the present invention, which includes an inner housing 10, a threaded sleeve 20, and a snap ring 30.

The inner shell 10 is provided with a boss 11. The boss 11 is located at the outer surface of the inner housing 10 and at the middle of the inner housing 10. Be equipped with first recess 12 on the boss 11, first recess 12 sets up on boss 11, can reduce the friction of other positions during the assembly. The first groove 12 includes two sidewalls 120 and a bottom wall 121. The two side walls 120 are parallel to each other. The bottom wall 121 is disposed between the two sidewalls 120 and perpendicular to the two sidewalls 120. An inclination angle 122 is provided at the intersection of one side wall 120 and the bottom wall 121, and the section of the inclination angle 122 is a straight line. The end of the inner shell 10 is provided with a plurality of gaps 14, and a plug-in part 13 is formed between two adjacent gaps 14. The plurality of inserting parts 13 are enclosed into a circle, and the plurality of inserting parts 13 can be folded for inserting through the gaps 14.

The screw sleeve 20 is provided with a second groove 21 and a receiving portion 22. The accommodating portion 22 extends through the entire screw sleeve 20. The second groove 21 is located in a concave position of the inner wall of the screw sleeve 20, so that friction of other parts during assembly is reduced. The second groove 21 communicates with the housing portion 22.

The snap ring 30 is a C-ring. The snap ring 30 is made of an elastic material. The thickness of the snap ring 30 is greater than the thickness of the first groove 12 and the second groove 21. The outer diameter of the snap ring 30 is larger than the outer diameter of the first groove 12.

When the separation preventing structure of the coaxial connector is installed, the snap ring 30 is snapped on the first groove 12, the inner housing 10 and the snap ring 30 are installed together in the threaded sleeve 20, and the snap ring 30 is shrunk in the snapping process. When the first groove 12 and the second groove 21 are located at the same position, the first groove 12 and the second groove 21 together form a clamping groove, and the snap ring 30 recovers deformation and is located in the clamping groove (half is located in the first groove 12, and the other half is located in the second groove 21), so that the threaded sleeve 20 and the inner shell 10 are not separated.

When the coaxial connector is used, the connector is screwed on the female head of adaptation, along with the increase of screwing force, the inner shell 10 and the thread insert 20 can receive a separating force, simultaneously, because the snap ring 30 has the existence of chamfer or R angle, when exerting force on an inclined plane or an arc surface, the force can be decomposed into 2 forces, at the same time, the snap ring 30 can receive a separating force and an inward extrusion force, the snap ring 30 can shrink and become small after receiving the extrusion force, the inner diameter of the snap ring 30 can touch the inclination angle 122, the inclination angle 122 prevents the snap ring 30 from continuing to become small, the inward extrusion force on the snap ring 30 is offset when receiving the resistance, the outer diameter of the snap ring 30 is not less than the inner diameter of the second groove 21 of the thread insert 20, the effect is still realized, and the thread insert 20 can not fall off from the inner shell 10.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, variations and modifications can be made without departing from the spirit of the utility model, and all equivalent modifications and changes can be made to the above embodiments according to the essential technology of the utility model, which falls into the protection scope of the utility model.
