The technical solution of the present invention will be explained with reference to specific embodiments.

As shown in fig. 1-3, a card-type radio frequency connector includes a central conductor 1, an outer shell 3 and a set of insulators 2; the central conductor 1 is arranged in the outer shell 3, a boss 11 is arranged on the central conductor 1, the insulator 2 is positioned between the central conductor 1 and the outer shell 3, a circle of elastic split structure 21 is arranged on the periphery of the insulator 2, and a circle of groove 31 is arranged along the inner wall of the outer shell 3;

after the insulator 2 is arranged between the central conductor 1 and the outer shell 3, the end face of the insulator 2 abuts against the boss 11, and the end part of the elastic split structure 21 is clamped into the groove 31 under the action of elasticity.

According to the invention, the insulator with the elastic split structure is arranged, the groove is arranged on the inner wall of the outer shell, and the boss structure is arranged on the central conductor, so that after the insulator is inserted from two sides, the front end of the insulator is just abutted against the boss, and meanwhile, the end part of the elastic split structure can be clamped into the groove under the action of elasticity, at the moment, the relative position relation among the insulator, the central conductor and the outer shell can be locked, uncertain factors caused by part deformation generated by press mounting can not occur, and the quality of a product can be ensured.

The boss 11 may be specifically configured as a ring of convex structure disposed along the outer periphery of the central conductor 1, and the central conductor 1 may be configured as either a solid conductor 13 or a hollow conductor 12, which is not specifically limited herein.

In an realizable manner, the elastic split structure 21 comprises a cylinder body 214 arranged outside the insulator 2, a plurality of split grooves 211 uniformly arranged along the circumference of the cylinder body 214, and hanging platforms 212 arranged at the ends of the cylinder body 214; the cylinder 214 is arranged coaxially with the insulator 2, and the hanging table 212 can abut against the side wall of the groove 31; the hanging platform 212, the cylinder 214 and the insulator 2 may be integrally formed, and the peripheral surface of the hanging platform 212 may be provided with an inclined surface 213 to facilitate the forward pushing of the elastic split structure 21 when the insulator 2 is inserted.

Because a circle of cylinder body 214 with a plurality of split grooves 211 is arranged outside the insulator 2, and the split grooves are evenly distributed on the cylinder body 214, so that the elastic split structure has elastic deformation force along the radial direction, when the insulator 2 is inserted, the elastic split structure is firstly in a compressed state, when the hanging platform 212 at the end part of the cylinder body 214 is inserted to the position of the groove 31, the hanging platform 212 can extend into the groove 31 under the action of elastic force, furthermore, because the hanging platform 212 is arranged, the hanging platform 212 can be just clamped at the position of the side wall of the groove 31, and the arrangement of the boss 11 enables the adjacent end of the insulator 2 and the central conductor 1 to generate acting force, when the insulator 2 is inserted from two sides, the insertion end parts of the insulators 2 at two sides are both abutted against the boss 11, and the hanging platforms 212 on the insulators 2 at two sides are clamped at the position of the side wall of the groove 31, so that the insulator 2 is pushed, the position of the central conductor 1 is not changed because of the blocking effect of the insulators 2 on the two sides, and the relative position relation among the insulator 2, the central conductor 1 and the outer shell 3 is locked finally.

The embodiments given above are preferable examples for implementing the present invention, and the present invention is not limited to the above-described embodiments.
