Description

Technical Field

[0001] This utility model relates to the technical field of helium testing fixtures, and in particular to a helium testing connector for a water-cooled plate of a new energy vehicle battery. Background Technology

[0002] Helium gas chromatography-mass spectrometry (GC-MS) leak detection technology has become the "gold standard" for testing the sealing performance of high-end radiators due to its extremely high detection sensitivity, rapid response characteristics, and non-destructive testing advantages. This technology uses helium as a tracer gas, precisely detecting its escape amount through specialized equipment to determine whether a leak has occurred and its extent. However, to efficiently and reliably apply this advanced detection technology to specific radiator products, it requires precisely matched specialized testing fixtures (grips) as support.

[0003] Existing as Figure 1 The connecting pipe of the water-cooled plate shown is required to be connected to the testing fixture. It includes a pipe body and a convex ring set on the pipe body. The difficulty in clamping the connecting pipe is that its pipe end is not a straight round pipe. The side wall of its pipe end is tapered. The general testing fixture can only seal the end face of the pipe end. However, due to the small end face area of ​​the tapered pipe end, the sealing between the testing fixture and the pipe end is poor. Utility Model Content

[0004] In order to facilitate the sealing and clamping of connecting pipes with tapered sidewalls at the pipe ends by the testing fixture, this application provides a helium test connector for water-cooled plates of new energy vehicle batteries.

[0005] The technical solution provided in this application for a helium detector connector for a water-cooled plate of a new energy vehicle battery is as follows: A helium detector connector for a water-cooled plate of a new energy vehicle battery includes a fixed tube fixed to a tooling body, a movable tube movably sleeved outside the fixed tube, a rubber sealing ring, and several clamping segments that clamp the connecting tube and limit the protrusion. The clamping segments can be spliced ​​into a complete circle. The top of each clamping segment has an integrally formed protrusion. A steel wire ring is embedded around the periphery of each protrusion. The protrusion has a groove for embedding the steel wire ring. The fixed tube has a slot for the protrusion to be engaged. The protrusion is inclined near the inner side of the fixed tube. The inner wall of the movable tube slides against the side wall of the clamping segment. The end of each clamping segment has a protrusion to prevent the movable tube from falling off. The movable tube has a groove adapted to the protrusion. The rubber sealing ring is engaged inside the fixed tube. A slider is slidably disposed inside the fixed tube. A driving assembly is provided on the fixed tube to drive the slider to compress the rubber sealing ring. An elastic component is provided between the fixed tube and the movable tube.

[0006] Preferably, the slider has an air hole that connects to the inner cavity of the fixed tube, the air hole penetrates the side wall and end of the slider, and the side wall of the fixed tube has a groove for the air hole to slide through the pipeline.

[0007] Preferably, the drive assembly includes a connecting shaft, a cam, and a handle. The cam and the handle are integrally formed. The connecting shaft is connected to the top of the fixed tube and is arranged radially along the fixed tube. The connecting shaft passes through the cam. The cam has a connecting hole for the connecting shaft to pass through, and the eccentric part of the cam has an abutment plane.

[0008] Preferably, the elastic component includes a retaining ring and a spring. The retaining ring is bonded to the outside of the retaining tube and is arranged circumferentially along the retaining tube. The spring is sleeved on the outside of the retaining tube, with one end of the spring abutting against the retaining ring and the other end abutting against the movable tube.

[0009] Preferably, the fixing tube has an installation groove, which is arranged along the circumference of the fixing tube, and a nylon washer is fitted in the installation groove, which is located below the rubber sealing ring.

[0010] In summary, this application includes the following beneficial technical effects: This utility model provides a helium test connector for a water-cooled plate of a new energy vehicle battery. Through the downward pressure of the movable tube and the constraint of the steel wire ring, multiple clamping flaps synchronously and stably contract centripetally and fit tightly against the connecting tube, effectively limiting the convex ring on the connecting tube. By driving the slider to slide inside the fixed tube through the drive component, a stable and uniform extrusion force can be applied to the rubber sealing ring, which is conducive to the rubber sealing ring fully deforming and filling the gap between the end of the connecting tube and the fixed tube, forming a reliable seal. This achieves the effect of making it easy for the testing fixture to seal and clamp the connecting tube with a tapered sidewall at the end. Attached Figure Description
