[0005] The floating joint on the existing floating connector can only swing around the center and cannot rotate in the circumferential direction, which is not conducive to the floating deviation insertion during the male and female joint insertion process. UTILITY MODEL CONTENT

[0006] In view of the deficiencies of the prior art, the utility model provides a small pad floating radio frequency connector, and the floating joint can be floating adjusted to adapt to the tolerance matching.

[0007] To achieve the above purpose, the utility model provides the following technical scheme:

[0008] A small pad floating radio frequency connector, comprising a fixed base and a floating joint, the fixed base comprises a fixed outer conductor and a fixed insulator connected; the floating joint comprises a floating outer conductor, a floating insulator and a floating inner conductor, which are sequentially arranged from outside to inside and are connected; characterized in that: the floating outer conductor is provided with an elastic sheet inward, and the top of the elastic sheet is elastically abutted with the outer wall of the fixed outer conductor; the lower end of the floating outer conductor is provided with an elastic hook, and the fixed insulator is provided with a radial bone extending outward, which is inserted into the elastic hook.

When the floating insulator rotates forward, the convex diameter abuts against one side of the concave position, and when the floating insulator rotates reversely, the convex diameter abuts against the other side of the concave position. In this way, between the gap between the convex diameter and the concave position, the floating insulator can smoothly swing around the fixed insulator as the axis, and the convex diameter on the fixed insulator is also the downward limit of the floating insulator.

[0014] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0015] 1. The floating outer conductor and the fixed outer conductor are electrically connected. When the tolerance is generated during plugging, the floating outer conductor, the floating insulator and the floating inner conductor are compressed by external force. At this time, the elastic section in the middle of the floating inner conductor is deformed to realize the up-and-down floating and circumferential swinging adjustment of the floating inner conductor. The elastic sheet on the floating outer conductor elastically abuts against the outer wall of the fixed outer conductor, and the elastic hook at the lower end of the floating outer conductor cooperates with the diameter gap on the fixed insulator. In this way, the fixed insulator does not affect the swinging of the floating outer conductor within the set range, and also limits the upward floating space of the floating outer conductor to adapt to the tolerance matching of the floating outer conductor.

[0016] 2. The floating insulator and the fixed insulator are cooperated through the convex diameter and the concave position gap. Between the gap between the convex diameter and the concave position, the floating insulator can smoothly swing around the fixed insulator as the axis to adapt to the tolerance matching of the floating connector and the male connector in the circumferential direction. Meanwhile, the convex diameter on the fixed insulator is also the downward limit of the floating insulator. When the floating connector is pressed downward, the top end of the convex diameter supports the floating insulator upward to limit the downward limit position of the floating insulator. The structure is simple and practical. BRIEF DESCRIPTION OF DRAWINGS

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0030] Please refer to Figures 1-7 A small-pad floating radio frequency connector, comprising a fixed base and a floating joint.

[0031] In the present application, the fixed base comprises a fixed outer conductor 5 and a fixed insulator 3 which are fixedly connected.

[0032] In the present application, the floating joint comprises a floating outer conductor 1, a floating insulator 2 and a floating inner conductor 4, which are sequentially arranged from outside to inside and fixedly connected. The upper part of the floating inner conductor 4 is a plug joint, the middle part is an elastic section 401, and the lower end is an inner conductor solder leg. The elastic section 401 is inserted into the center hole of the fixed base, so that the floating joint can be adjusted floatingly with the fixed base as the center axis.

[0033] In the application, the lower part of the floating outer conductor 1 is stamped to form an elastic piece 101 which is bent inward, and the top of the elastic piece 101 elastically abuts against the outer wall of the fixed outer conductor 5, so that the floating outer conductor 1 is electrically connected with the fixed outer conductor 5, and the floating outer conductor 1 is in contact with and movably cooperates with the fixed outer conductor 5.

[0034] In order to limit the movement range of the floating outer conductor 1, in the application, the lower end of the floating outer conductor 1 is provided with an elastic hook 100, the elastic hook 100 includes a pair of hooks, the fixed insulator 3 is provided with a radial bone 305 extending outward, the radial bone 305 is inserted into the elastic hook 100, and the hooks on the elastic hook 100 are located just below the radial bone 305. When the floating outer conductor 1 is not deflected, the radial bone 305 and the elastic hook 100 have a gap therebetween, and when the floating outer conductor 1 moves upward or is deflected, the radial bone 305 limits the upward movement or deflection of the elastic hook 100, so that the radial bone 305 does not affect the swing of the floating outer conductor 1 within the set range, and limits the upward floating space of the floating outer conductor 1 to adapt to the tolerance of the floating outer conductor 1, and meanwhile, the structure of the floating outer conductor 1 and the fixed insulator 3 is simple, easy to form, and low in manufacturing cost.

[0035] When the female connector is connected with the male connector, the elastic section 401 on the floating inner conductor 4 can be elastically supported, the floating outer conductor 1, the floating insulator 2 and the head of the floating inner conductor 4 are offset and floated up and down under pressure, and are elastically reset through the elastic section 401 after losing the pressure, so that the correct plug-in with the male connector is realized.

[0036] In the application, the fixed insulator 3 is provided with an outer ring 306, the fixed insulator is in a hollow columnar shape and is arranged at the center of the outer ring 306, the outer ring 306, the radial bone 305 and the fixed insulator 3 are integrally injection molded into an integrated structure. The radial bone 305 is arranged between the inner wall of the outer ring 306 and the outer wall of the fixed insulator 3. The outer ring 306 has a shielding effect of hiding the elastic piece 101 and the radial bone 305 in the outer ring 306, and also has a protective effect of protecting the elastic piece 101, so that the situation that the floating outer conductor 1 is excessively deflected and causes the failure of the connector is avoided.

[0037] In the application, the elastic piece 101 has four, and the four elastic pieces 101 are circumferentially distributed.

[0038] In the application, the fixed outer conductor 5 is clamped on the fixed insulator 3, the floating outer conductor 1 is arranged on the outer side of the floating insulator 2, the floating insulator 2 is opposite to the fixed insulator 3, and the floating inner conductor 4 is arranged in the floating insulator 2.

[0039] In the application, the floating insulator 2 and the fixed insulator 3 are matched through the convex diameter 302 and the concave position 201.

In this way, the floating insulator 2 can swing smoothly with the fixed insulator 3 as the center in the gap between the convex diameter 302 and the concave position 201. The convex diameter 302 on the fixed insulator 3 is also the downward limit of the floating insulator 2. When the floating connector is pressed downward, the top end of the convex diameter 302 supports the floating insulator 2 upward to limit the downward limit position of the floating insulator 2.

[0040] In the application, the bottom end of the floating insulator 2 has a spherical protrusion 202, and the top end of the fixed insulator 3 is provided with a concave part 303 capable of matching the spherical surface of the spherical protrusion 203. During the plug-in process, the floating insulator 2 is pressed downward, and the spherical protrusion 203 is supported in the concave part 303 and rotates, so that the floating connector can be adjusted as the center of the fixed base during the plug-in and plug-out connection of the male connector and the female connector, and the elastic section 401 on the floating inner conductor 4 is prevented from being damaged due to excessive pressing.

[0041] In the application, the top end of the floating outer conductor 1 has a plurality of guide springs 102, and the guide springs 102 are used for elastic contact with the outer conductor of the male connector. Specifically, the top end of the floating outer conductor 1 has a plurality of guide springs 102, and the plurality of guide springs 102 are opened from bottom to top. The plurality of guide springs 102 form a main body which is wide at the top and narrow at the bottom, and guide the floating connector when the male connector is connected. The guide springs 102 are distributed with a certain interval, and elastically deform toward the center when compressed, so as to realize elastic contact.
