Its primary function is to absorb heat generated by heating components and conduct it away through the coolant flowing through it. The airtightness of the liquid cold plate is a key indicator of its performance, as poor airtightness can lead to coolant leakage, impacting battery performance and safety. Therefore, before a liquid cold plate is put into operation, it must undergo rigorous airtightness testing to ensure its safety and reliability.

[0003] In the prior art, the locking structure of the connector is relatively simple in design and may only include a basic snap connection or a threaded connection.

[0004] This results in a relatively weak locking structure for the air tightness detection joint, and the joint can only be used on one type of faucet, resulting in poor compatibility. Utility Model Content

[0006] To achieve the above-mentioned object, the utility model provides a joint for testing the air tightness of a liquid cooling plate, comprising a joint body and a connecting assembly;

[0007] The connecting assembly includes an upper limit buckle, a lower limit buckle and multiple positioning pins. The upper limit buckle is slidably connected to the joint body and is located on the upper side of the joint body. The lower limit buckle is slidably connected to the joint body and is located on the lower side of the joint body. The multiple positioning pins are respectively inserted into the joint body to fix the upper limit buckle and the lower limit buckle to the joint body.

[0008] Among them, the joint body has two grooves, which are respectively located on the upper and lower sides of the joint body, and respectively cooperate with the upper limit buckle and the lower limit buckle. The upper limit buckle and the lower limit buckle have extension parts on the side close to the joint body, and the extension parts extend into the grooves.

[0009] Wherein, the connector body has a plurality of positioning pin holes, and the plurality of positioning pin holes are respectively distributed on the upper and lower sides of the connector body and matched with the positioning pins.

[0010] Wherein, the joint for air tightness testing of the liquid cooling plate further includes two sealing rings, which are respectively fixedly connected to the joint body and are respectively located on the inner side of the joint body.

[0011] Wherein, the joint for testing the air tightness of the liquid cooling plate further includes an air pipe quick plug, which is fixedly connected to the joint body and is located at the end of the joint body.

[0012] The utility model provides a joint for testing the air tightness of a liquid cooling plate. When installing the joint, the tails of the upper limit buckle and the lower limit buckle are pressed downward steadily and evenly, the upper limit buckle and the lower limit buckle are opened outward, the joint body is gently pressed onto the water spout, and the position is adjusted until the upper limit buckle and the lower limit buckle are stuck in the water pipe groove, which means that the joint installation is complete. When disassembling the joint, the tails of the upper limit buckle and the lower limit buckle are pressed downward steadily and evenly until the bracket is disengaged from the water spout groove, and the tails of the upper limit buckle and the lower limit buckle are pressed and gently pulled upward to complete the disassembly of the joint. The upper limit buckle and the lower limit buckle can both be relatively displaced with the joint body to achieve matching for water spouts of different lengths and specifications, thereby improving the compatibility of the joint.

[0022] In this specific embodiment, the upper limit buckle 102 is slidably connected to the connector body 101 and is located on the upper side of the connector body 101. The lower limit buckle 103 is slidably connected to the connector body 101 and is located on the lower side of the connector body 101. A plurality of positioning pins 104 are respectively inserted into the connector body 101 to fix the upper limit buckle 102 and the lower limit buckle 103 to the connector body 101. The rear protrusions of the upper limit buckle 102 and the lower limit buckle 103 extend into the connector body 101, respectively, and can move relative to each other on the upper and lower sides of the connector body 101. There are four positioning pins 104, which are respectively inserted into the connector body 101 and are located on both sides of the protrusions of the upper limit buckle 102 and the lower limit buckle 103, thereby limiting the upper limit buckle 102 and the lower limit buckle 103, fixing the limit buckle to the connector body 101, and improving structural stability. The improvement of the upper limit buckle and the lower limit buckle 103 is intended to improve the connection reliability between the connector and the liquid cooling plate water nozzle, and effectively combine the connector and the liquid cooling plate water nozzle tightly without the risk of loosening.

[0023] The connector body 101 has two grooves 105, which are located on the upper and lower sides of the connector body 101 and respectively cooperate with the upper limit buckle 102 and the lower limit buckle 103. The upper limit buckle 102 and the lower limit buckle 103 have extensions 106 on the side close to the connector body 101, and the extensions 106 extend into the grooves 105.
