[0002] In the field of power batteries, liquid cooling systems are often used to cool the battery cells.

Example
[0022] like Figs. 1-3 As shown, this application discloses a sealing connector for a liquid cooling piping system, comprising a male connector 100 and a female connector 200 that mates with the male connector 100.

The outer shell 211 is sleeved on the steel ball sleeve 208 through the outer shell retaining spring 212 and restricts a number of steel balls 209 in the steel ball holes of the steel ball sleeve 208. Through the above structural design, the male head 100 and the female head 200 can not only achieve rapid coupling, but also are not easy to fall off after coupling, have stable locking, and are easy to use.
[0023] Specifically, the female valve seat 201 is provided with an internal thread, the female cavity 205 is provided with a first external thread that mates with the internal thread of the female valve seat 201, the steel ball sleeve 208 is provided with an internal thread, and the female cavity 205 is provided with a second external thread that mates with the internal thread of the steel ball sleeve 208.
[0024] Specifically, a first annular inclined surface 2041 is provided on the outer wall surface of the female valve core 204, and a second annular inclined surface 2051 that cooperates with the first annular inclined surface 2041 is provided on the inner wall surface of the female cavity 205.
[0025] Specifically, the outer protrusion on the outer wall of the sliding sleeve 207 is provided with a first limiting surface 2071, and the inner protrusion on the inner wall of the steel ball sleeve 208 is provided with a second limiting surface 2081 that cooperates with the first limiting surface 2071.
[0026] Specifically, the sliding sleeve 207 has a third annular inclined surface 2072 at one end relative to its outer protrusion, and the outer protrusion on the outer wall of the male head body 101 has a fourth annular inclined surface 1011 that cooperates with the third annular inclined surface 2072.
[0027] Specifically, the inner wall of the outer shell 211 is provided with a fifth annular inclined surface 2111 that cooperates with a plurality of steel balls 209, and the outer protrusion on the outer wall of the male head body 101 is also provided with a sixth annular inclined surface 1012 that cooperates with a plurality of steel balls 209.
[0028] Specifically, a first sealing ring 2011 is provided on the outer wall surface of the female valve seat 201 near the steel ball sleeve 208, a second sealing ring 2052 is provided between the outer wall surface of the female cavity 205 and the inner wall surface of the female valve seat 201, a third sealing ring 2053 is provided between the inner wall surface of the female cavity 205 and the outer wall surface of the male body 101, a fourth sealing ring is sleeved on the end of the valve stem near the male valve core, and a sixth sealing ring is sleeved on the end of the male valve core near the valve stem.
[0029] like Figs. 4-6 As shown, in the initial blocking state, the female valve core 204 is in a sealed state, and the end face of the female valve core 204 is coplanar with the end face of the valve stem 202; the sliding sleeve 207 is pushed by the sliding sleeve spring 206 and controlled by the first limiting surface and the second limiting surface, and the sliding sleeve 207, the outer shell 211, and the steel ball sleeve 208 constitute a steel ball limiting structure, at which time the female head 200 is in a pre-coupled state; the fourth annular inclined surface 1011 of the male head body and the third annular inclined surface 2072 of the sliding sleeve 207 are in just contact, at which time the end faces of the male and female heads are in a pre-coupled state. The connection is just about to make contact, but the flow channel of the connector is not connected. II. Coupling process: The second annular inclined surface of the female head cavity pushes the sliding sleeve 207 axially towards the female head, compressing the sliding sleeve spring 206, until the fourth annular inclined surface of the male head body contacts the third annular inclined surface of the sliding sleeve. During this process, the steel ball is released from its limiting position, and the outer shell loses the limiting position of the steel ball, thus being pushed by the outer shell spring towards the male head until the fifth annular inclined surface of the outer shell contacts the outer shell retaining spring. During this process, the fifth annular inclined surface of the outer shell pushes the steel ball inward until it is at its limiting position, until... Fig. 6At the indicated position, the steel ball contacts the sixth annular inclined surface of the male head body, thus forming a limiting structure together with the outer shell and steel ball sleeve, thereby achieving coupling between the male and female heads. During the movement of the locking mechanism, the male head body pushes the female head valve core to move towards the female head, compressing the female head valve core spring. The fourth sealing ring on the male head valve core achieves flow channel sealing with the outer wall of the male head body. The valve stem pushes the male head valve core to move towards the male head, compressing the male head valve core spring. The internal flow channel of the connector gradually opens until the male and female heads are coupled, as shown. Fig. 6 As shown, the flow channel of the connector is fully connected at this time; III. Decoupling process: During decoupling, pull the outer shell towards the female valve seat to compress the outer shell spring. At this time, the steel ball is released from the coupling limit, and the male and female valve core springs start to work, pushing the male body out of the female cavity. At the same time, the fourth ring of the male body pushes the steel ball outward, and the sliding sleeve is pushed towards the male direction by the sliding sleeve spring until the limit surface 1, so that the steel ball is in the pre-coupling state again, as shown in state one. At this time, the female valve core and the male valve core are reset, the flow channel of the connector is cut off, and the self-sealing action is completed.
[0030] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, good stability, and ease of application.
