[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] One embodiment of this application provides an airtight test connector for the non-threaded inlet and outlet of a heat sink, such as... Figures 1-5 As shown, it includes: a transition sleeve 2 that mates with the oil inlet / outlet 11 of the nozzle, the transition sleeve 2 being threadedly connected to an adapter nut 3, the adapter nut 3 being connected to the corresponding interface of the gas tightness testing equipment; it should be noted that the structure and operation of the gas tightness testing equipment are existing technologies and will not be described in detail here. The focus of this application is: how to achieve the connection between the oil inlet / outlet 11 of the nozzle and the corresponding interface of the gas tightness testing equipment; The transition sleeve 2 includes a first transition sleeve 21 and a second transition sleeve 22, which cooperate to form a complete transition sleeve 2. A protrusion 211 is formed on the side end face of the first transition sleeve 21, and a groove 221 is formed on the side end face of the second transition sleeve 22 to cooperate with the corresponding protrusion 211. The first transition sleeve 21 and the second transition sleeve 22 are connected by the protrusion 211 and the groove 221, making the connection between them more convenient. A first inner annular groove 212 is formed on the inner side of the first transition sleeve 21 near its upper end face, which cooperates with the flange 12 of the oil inlet / outlet port 11 of the nozzle. The second transition sleeve 22 is formed near its upper end face... The inner side of the sleeve has a second inner ring groove 222 that mates with the flange 12 of the oil inlet / outlet 11 of the nozzle. During connection, the first inner ring groove 212 and the second inner ring groove 222 mate with the corresponding flange 12. Then, the first transition screw half sleeve 21 and the second transition screw half sleeve 22 are connected by the engagement of the protrusion 211 and the groove 221, so as to connect the transition screw sleeve 2 with the oil inlet / outlet 11 of the nozzle. The outer side of the first transition screw half sleeve 21 has a first external thread, and the outer side of the second transition screw half sleeve 22 has a second external thread. The first external thread on the outer side of the first transition screw half sleeve 21 and the second external thread on the outer side of the second transition screw half sleeve 22 constitute a complete external thread to facilitate the threaded connection of the adapter nut 3.

[0017] Furthermore, in one embodiment, as Figure 5 As shown, the lower ends of the first transition screw half-sleeve 21 and the second transition screw half-sleeve 22 are respectively formed with first polygonal flat edges 23 to facilitate the rotation of the wrench.

[0018] Furthermore, in one embodiment, as Figure 3 As shown, the adapter nut 3 includes an adapter nut body 31. The adapter nut body 31 has a connecting recess 32 that mates with the upper part of the transition sleeve 2. The inner side of the connecting recess 32 is threaded to the external thread of the transition sleeve 2. Rotating the adapter nut 3 fixes the transition sleeve 2 relatively, so that the adapter nut 3 and the transition sleeve 2 are tightened or separated. The nut body 31 has a threaded through hole 33, which communicates with the connecting recess 32 and is connected to the corresponding interface of the gas tightness test equipment.

[0019] In one embodiment, such as Figure 2 As shown, the outer side of the nut body 31 has a second polygonal flat edge 34 for easy wrench engagement.

[0020] In one embodiment, such as Figure 3 As shown, it also includes an O-ring 4, which is located at the bottom of the connecting recess 32. After installation, the O-ring 4 presses against the end face of the oil inlet / outlet 11 of the light tube nozzle to achieve a sealing effect. The connecting recess 32 has an installation groove for installing the O-ring 4.

[0021] In use, the first transition screw half-sleeve 21 and the second transition screw half-sleeve 22 are fitted onto the oil inlet / outlet 11 of the light nozzle. An O-ring 4 is placed in the connecting recess 32 of the adapter nut 3. The adapter nut 3 is then screwed onto the transition screw sleeve 2. At this time, the flange 12 of the oil inlet / outlet 11 of the light nozzle acts as a limit, allowing the O-ring 4 inside the adapter nut 3 to press smoothly onto the end face of the oil inlet / outlet 11 of the light nozzle while the position of the transition screw sleeve 2 remains unchanged, ensuring a seal. Finally, tighten with a wrench. After the fixture is installed, the air inlet connector can be connected to the threaded through hole 33.
