Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0024] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0025] refer to Figures 1-9 .

[0026] This utility model provides a miniature radio frequency test connector, including a test socket 1 and a test plug 2. The test socket 1 includes a housing 10, and the housing 10 includes a top panel 100. A probe socket 101 is provided through the top panel 100. The test plug 2 includes a shielding ring 20 and a probe 21 disposed in the inner ring of the shielding ring 20. The shielding ring 20 includes a shielding ring body 22 and an insertion positioning part 202 connected to the inner edge of the bottom end of the shielding ring body 22. The insertion positioning part 202 can be inserted into the probe socket 101, and the bottom end of the probe 21 extends beyond the bottom end face of the insertion positioning part 202.

[0027] Its working principle is as follows: by setting an insertion positioning part 202 along the inner edge of the bottom end of the shielding ring body 22, during testing, the insertion positioning part 202 can be inserted into the probe socket 101 to realize the connection between the test plug 2 and the test socket 1. This can greatly reduce the size of the test plug 2, meet the customer's small-pitch arrangement requirements when multiple RF test sockets are used at the same time, and has good connection stability and can be repeatedly plugged and unplugged.

[0028] Example 1, as shown in the appendix Figure 4 , 6 As shown, the shielding ring body 22 includes an outer ring 200 and an inner ring 201 disposed inside the outer ring 200. The top end of the outer ring 200 is connected to the top end of the inner ring. The insertion positioning part 202 includes a plurality of arc-shaped connecting plates 202a evenly distributed at the bottom end of the inner ring 201 and extending beyond the bottom end surface of the outer ring 200. The bottom outer edge of the arc-shaped connecting plate 202a is provided with a buckle part 202b. When the insertion positioning part 202 is inserted into the probe insertion hole 101, the buckle part 202b can be fastened to the probe insertion hole 101. The top outer edge of the buckle part 202b is provided with a first guide slope 202a. Specifically, when the insertion positioning part 202 is inserted into the probe socket 101, the buckle part 202b can be fastened onto the probe socket 101 to achieve the connection and fixation of the test plug 2 and the test base 1; when it is necessary to remove the test plug 2, the insertion positioning part 202 is pulled outward from the test base 1, the first guide slope 202a will abut against the bottom edge of the probe socket 101, the bottom end of the inner ring 201 will elastically contract, and the buckle part 202b will disengage from the probe socket 101, thereby pulling the insertion positioning part 202 out of the probe socket 101.

[0029] Based on the above embodiments, a second guide slope 101a is provided on the inner edge of the top end of the probe insertion hole 101, which can play a role in avoiding and guiding the undercut part 202b, and reducing the wear of the undercut part 202b.

[0030] Example 2, as shown in the appendix Figure 7 , 8 As shown, the outer edge of the insertion positioning part 202 is provided with a third guide slope 202d. During testing, the insertion positioning part 202 is inserted into the probe socket 101. When the third guide slope 202d abuts against the inner wall of the probe socket 101, the bottom end face of the shielding ring body 22 abuts against the top surface of the top panel 100.
