[0031] Further, it further includes a dielectric ring 5. The dielectric ring 5 is sleeved on the outer periphery of the tail pin 11, and the dielectric ring 5 is arranged between the inner conductor 4 and the outer conductor 12.

[0032] As can be seen from the above description, adding the dielectric ring 5 can achieve performance compensation and also play a shielding effect to prevent the inner conductor 4 and the outer conductor 12 of the radio frequency connector 1 to be tested from being conductively connected through air and causing a short circuit.

[0033] Further, the projection of the inner conductor 4 on the plane where the end face of the dielectric ring 5 is located does not protrude beyond the end face of the dielectric ring 5.

[0035] Further, the mounting assembly 3 includes a mounting cover plate 31 and a connecting member 32. The mounting cover plate 31 is detachably connected to the housing 2 through the connecting member 32, and a partial area of the RF connector 1 is clamped between the mounting cover plate 31 and the housing 2.

[0039] Further, the mounting cover plate 31 is annular, and the mounting cover plate 31 is sleeved on the outer periphery of the RF connector 1.

[0040] As can be seen from the above description, the annular mounting cover plate 31 can provide uniform pressure on the periphery of the RF connector 1 to be tested, and avoid the RF connector 1 tilting relative to the housing 2.

[0041] Further, the number of the connecting members 32 is multiple, and the multiple connecting members 32 are evenly distributed around the circumference of the mounting cover plate 31.

[0042] As can be seen from the above description, the even distribution of the multiple connecting members 32 around the circumference of the mounting cover plate 31 can provide uniform pressure on the periphery of the RF connector 1 to be tested, and avoid the RF connector 1 tilting relative to the housing 2.

[0043] Further, limiting ring grooves 21 are respectively arranged at both ends of the inner peripheral surface of the housing 2, and the outer peripheral edge of the RF connector 1 is arranged in the limiting ring grooves 21.

[0045] Please refer to Figures 1 to 3, Embodiment 1 of the present utility model is: A radio frequency connector test tooling for testing a radio frequency connector 1, where the radio frequency connector 1 includes a tail pin 11, an outer conductor 12, and a connector housing 13 sleeved from the inside out in sequence. The radio frequency connector test tooling includes a housing 2, a mounting assembly 3, and an inner conductor 4.

Just fix two radio frequency connectors 1 to be tested at both ends of the housing 2 through the mounting assembly 3, and insert the tail pins 11 of the two radio frequency connectors 1 to be tested into the jacks 41 at both ends of the inner conductor 4 respectively, and then the two radio frequency connectors 1 to be tested can be connected to the test equipment for testing.

[0046] To facilitate the insertion of the tail pin 11 of the radio frequency connector 1 to be tested into the jack 41, as Figure 3 shown, a chamfer structure is provided at the opening of the jack 41.

[0047] As Figure 3 shown, a plurality of notches 42 are respectively opened at both ends of the inner conductor 4. The plurality of notches 42 are arranged around the circumference of the inner conductor 4, and the plurality of notches 42 communicate the outer peripheral surface of the inner conductor 4 and the jack 41. It is easy to understand that an elastic arm is formed between two adjacent notches 42 at the end of the inner conductor 4, which can undergo elastic deformation to facilitate the insertion of the tail pin 11 of the radio frequency connector 1.

[0048] As Figure 2 shown, the radio frequency connector test tooling further includes a dielectric ring 5. The dielectric ring 5 is sleeved on the outer periphery of the tail pin 11, and the dielectric ring 5 is disposed between the inner conductor 4 and the outer conductor 12.

Adding the dielectric ring 5 can achieve performance compensation and also play a shielding effect to prevent the inner conductor 4 and the outer conductor 12 of the radio frequency connector 1 to be tested from conducting through the air and causing a short circuit.

[0049] To improve the shielding ability of the inner conductor 4, as Figure 2 shown, the projection of the inner conductor 4 on the plane where the end face of the dielectric ring 5 is located does not protrude from the end face of the dielectric ring 5. Specifically, the inner diameter of the end face of the inner conductor 4 is greater than or equal to the inner diameter of the end face of the dielectric ring 5, and the outer diameter of the end face of the inner conductor 4 is less than or equal to the outer diameter of the end face of the dielectric ring 5.

[0050] As Figure 1 and Figure 2As shown, the installation component 3 includes an installation cover plate 31 and a connecting member 32. The installation cover plate 31 is detachably connected to the housing 2 through the connecting member 32, and a partial area of the RF connector 1 is clamped between the installation cover plate 31 and the housing 2.

The number of the connecting members 32 is multiple, and the multiple connecting members 32 are evenly distributed around the circumference of the installation cover plate 31.

[0052] As Figure 2 shown, limiting ring grooves 21 are respectively provided at both ends of the inner peripheral surface of the housing 2, and the outer peripheral edge of the RF connector 1 is arranged in the limiting ring grooves 21. The limiting ring grooves 21 are used to limit the relative positions of the housing 2 and the RF connector 1 to be tested.

[0053] In summary, the RF connector test tooling provided by the present utility model can be applicable to testing RF connectors without installation holes or threaded holes. Only need to fix two RF connectors to be tested at both ends of the housing through the installation component, and insert the tail pins of the two RF connectors to be tested into the jacks at both ends of the inner conductor respectively. Subsequently, the two RF connectors to be tested can be connected to the test equipment for testing. The chamfer structure can facilitate the insertion of the tail pins of the RF connectors to be tested into the jacks. An elastic arm is formed between two adjacent notches at the end of the inner conductor, which can undergo elastic deformation to facilitate the insertion of the tail pins of the RF connector. Adding a dielectric ring can achieve performance compensation and also play a shielding effect to prevent the inner conductor and the outer conductor of the RF connector to be tested from being conductively connected through the air, resulting in a short circuit. The limiting ring groove is used to limit the relative positions of the housing and the RF connector to be tested.
