[0024] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] like Figures 1-9 The diagram shows a corrugated RF coaxial cable testing direct-insertion connector structure, with a connector body used in conjunction with the mating cable 17, such as... Figure 9 As shown, the connecting cable 17 includes an inner conductor 19 and an outer conductor 20. The outer conductor 20 is covered on the outer surface of the inner conductor 19. An insulation layer is provided between the outer conductor 10 and the inner conductor 19. The outer conductor 10 is also covered with a sheath.

[0026] The connector body includes a housing 18 and a pin 1. The inner cavity of the housing 18 is a stepped ring structure. The inner cavity of the housing 18 has a smaller left ring segment and a larger right ring segment. The inner cavity of the housing 18 is designed according to the required standard interface for the left ring segment and according to the required cable size for the right ring segment. At the same time, the diameter of the cable will affect the diameter of the right ring segment. Therefore, the right ring segment is not necessarily larger. The pin 1 is installed in the inner cavity of the housing 18.

[0027] An insulator 2 is installed in the middle ring section of the inner cavity of the outer casing 18, and the insulator 2 hugs the pin 1. An inner contact spring body 4 is installed at the end of the pin 1 facing the mating cable 17, and the inner contact spring body 4 is inserted into the inner conductor 19 of the mating cable 17.

[0028] An outer contact spring 3 is installed in the right annular cavity of the inner cavity of the outer casing 18 and is positioned by a positioning component. The outer contact spring 3 is in conjunction with the outer conductor 20 of the connecting cable 17.

[0029] The inner contact spring 4 and the outer contact spring 3 are coaxially arranged. The inner contact spring 4 and the outer contact spring 3 are inserted into the mating cable 17 and form elastic contact with the mating cable 17, thus completing the installation of the cable testing connector.

[0030] like Figure 3 As shown, the left end face of the right annular segment cavity in the inner cavity of the outer shell 18 is the positioning reference surface W.

[0031] Figures 7-8 As shown, the inner contact spring body 4 is made of silver-plated or gold-copper alloy, preferably copper alloy with a high elastic recovery coefficient. The inner contact spring body 4 is a tapered cone that tapers downwards. The cone end of the inner contact spring body 4 has a central shaft hole 8, in which the pin 1 is inserted. Several axially extending shrinkage grooves 9 are evenly provided on the side of the inner contact spring body 4. The cone bottom end of the shrinkage groove 9 is an open end, and the other end is a closed end. The shrinkage groove 9 divides the inner contact spring body 4 into several slotted spring pieces 10. The design of the slotted spring piece 10 needs to be designed according to the structure of the inner conductor 19. The elastic contact normal pressure between the slotted spring piece 10 and the inner conductor 19 can be adjusted to control the insertion and extraction force of the mating cable 17.

[0032] like Figures 5-6 As shown, the material of the outer contact spring body 3 is silver-plated or gold-copper alloy, preferably copper alloy with a high elastic recovery coefficient. The cross-sectional shape of the outer contact spring body 3 is "I" shaped. The outer contact spring body 3 has a hollow structure. Several contact grooves 11 extending axially are evenly opened on the side wall of the outer contact spring body 3. Both ends of the contact grooves 11 are closed ends. The contact grooves 11 divide the outer contact spring body 3 into several contact springs 12. Adjusting the effective contact diameter of the slotted spring 31 can control the insertion and extraction force of the mating cable 9.

[0033] like Figure 1 and Figure 3 As shown, the effective contact length L1 of the contact spring 12 is greater than the pitch dimension L2 of the mating cable 17, and the effective contact length L1 of the contact spring 12 is less than the maximum diameter D of the outer conductor of the mating cable 17. Adjusting the effective contact length of the contact spring 12 can control the insertion and extraction force of the mating cable 17.

[0034] The outer contact spring body 3 is divided into a left ring body 13, a middle ring body 14 and a right ring body 15 in sequence. The cross-sectional shape of the left ring body 13 and the right ring body 15 in the axial direction is "L" shaped. Several contact grooves 11 are opened on the ring wall of the middle ring body 14. The inner wall connection between the left ring body 13, the right ring body 15 and the middle ring body 14 is set with a rounded transition.

[0035] The outer casing 18 has a positioning ring groove at the right edge. A positioning element is installed in the positioning ring groove and abuts against the outer contact spring 3 to prevent the outer contact spring 3 from sliding out. The diameter of the positioning ring groove is larger than the diameter of the right ring cavity of the outer casing 18. The positioning element includes a first positioning block 5, a sealing ring 6, and a second positioning block 7 that are sequentially embedded in the positioning ring groove.

[0036] In addition, several anti-slip grooves 16 are provided on the outer surface of the housing 18 to increase the grip friction and facilitate the installation of the connecting cable 17.

[0037] Work process:

[0038] Step 1: Process the mating cable 9 so that the dimensions of the inner conductor 19 and the outer conductor 20 meet the requirements for contact between the outer contact spring 3 and the inner contact spring 4;

[0039] Step 2: As Figure 3 As shown, the outer conductor 20 is inserted into the outer contact spring 3, and the inner contact spring 4 is simultaneously inserted into the inner conductor 19, until the left end face of the mating cable 17 contacts the positioning reference surface W, as shown. Figure 4 As shown, this completes the installation of the through-hole connector for testing the corrugated RF coaxial cable;

[0040] Step 3: After testing the mating cable 9, simply unplug it. The connector can be reused.

[0041] The above description is only a specific embodiment of the present invention. Various examples and illustrations do not constitute a limitation on the substantive content of the present invention. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the specification without departing from the substance and scope of the invention.
