Referring now to fig. 1-3, fig. 1 illustrates a schematic structural view of a connector according to an embodiment of the present application, fig. 2 illustrates a schematic structural view of another view of the connector of fig. 1, fig. 3 illustrates an exploded view of the connector of fig. 1, and an embodiment of the present application provides a connector 100 for a cooling system of a battery device, including, but not limited to, a battery pack, an energy storage container, an energy storage cabinet, and the like. The connector 100 is provided with a communication flow passage 102, and at least two connectors 104 are formed on the connector 100, wherein one connector 104 is used for fluid inflow, the other connector 104 is used for fluid outflow, and the other connectors 104 can be arranged according to actual requirements. The joint 100 includes a main body 110 and a connection pipe body 120. One end of the connection pipe body 120 is connected to the main body 110, one joint 104 is formed at the other end of the connection pipe body 120, and a pipe (an internal flow passage) of the connection pipe body 120 forms at least part of the communication flow passage 102. Also, at least a portion of the pipe section of the connection pipe body 120 has a certain deformation allowance. It should be noted that, the other port 104 may be formed on the main body 110, so that a portion of the communication flow channel 102 is formed in the main body 110, and a portion of the communication flow channel 102 is formed in the connecting pipe 120; or another port 104 may be formed at an end of the connection pipe body 120 connected to the main body 110 such that the entire communication flow path 102 is disposed within the connection pipe body 120.

By arranging the connecting pipe body 120 on the main body 110, at least part of the pipe section of the connecting pipe body 120 has a certain deformation allowance and comprises a deformation part, when the connecting pipe is applied to a cooling system of battery equipment, the communication flow passage 102 of the joint 100 is communicated between a liquid port of a liquid cooling plate and a liquid valve or other pipelines, wherein one end of the connecting pipe body 120 far away from the main body 110 is communicated with the liquid valve or other pipelines, and as the at least part of the pipe section of the connecting pipe body 120 is the deformation part, when the liquid valve or other pipelines are collided by foreign objects, the bending leakage force of the deformation part of the connecting pipe body 120 is reduced, and the risk of fracture at the connection part caused by rigid collision is reduced or avoided; the deformed portion of the connection pipe body 120 may be automatically rebounded or manually corrected when no external force is applied, without affecting the normal use of the joint 100. The structure communicating with the connector 100 is not limited to a liquid valve and a pipeline, and may be other types of connectors or other devices for passing fluid.

Referring to fig. 4 and 5, in conjunction with fig. 3, fig. 4 shows a top view of the joint in the present embodiment, fig. 5 shows a cross-sectional view of the joint along line I-I in fig. 4, and the connecting tube 120 includes a hose segment 121 and a connecting segment 122 that are connected to each other, where an end of the hose segment 121 remote from the connecting segment 122 is connected to the main body 110. Since the hardness of the connection section 122 is greater than that of the hose section 121, it can improve the connection strength with the liquid valve or other pipeline, the hose section 121 plays a role of buffering, and the leakage force is transmitted to the connection section 122 due to the impact. It is understood that in other embodiments, the connecting pipe 120 is a hose as a whole, i.e. the connecting section 122 is also a hose, so as to have a better force release effect, and the material may be metal, plastic or a combination of metal and plastic.

Further, the hose segment 121 is a metal tube, at least part of the hose segment 121 is a corrugated segment 123, and the corrugated segment 123 is in communication with the connecting segment 122. The hose section 121 made of metal has certain rigidity, can not bend under normal conditions, does not affect normal use, and can bend towards the same direction after being subjected to certain external force so as to achieve the purpose of releasing force. It should be noted that, in other embodiments, the hose segment 121 may be a plastic tube, which may be connected to the main body 110 by an adhesive or a threaded connection, and connected to the connecting segment 122 by an adhesive, a threaded connection, or a clamping connection.

In this embodiment, the connection section 122 is also a metal tube, that is, the entire connection tube 120 is a metal tube, where the connection section 122 and the hose section 121 are welded, and the welding method may be, but is not limited to, brazing. Obviously, in other embodiments, the hose section 121 and the connecting section 122 which are made of metal materials can be integrally formed, so that the welding step is saved, the process is simplified, and the production efficiency is improved. In other embodiments, the connecting section 122 may be made of plastic, and has a certain rigidity, and may be connected to the metal hose section 121 by screwing or bonding.

In this embodiment, the portion of the tube section 121 is a flat tube section 124, and the rest is a corrugated tube section 123, and the flat tube section 124 is connected to the main body 110. The flat tube section 124 is made of a metal material with certain flexibility, so that the flat tube section can be deformed under stress and can also play a role in leakage. Obviously, the bellows segment 123 has better deformation properties, it is directly connected with the connection segment 122, and directly leaks the force to the connection segment 122, if the external force is too large, the flat tube segment 124 leaks the force further through deformation, and the risk of fracture at the connection of the bellows segment 123 and the flat tube segment 124 is reduced or avoided. It will be appreciated that in other embodiments, the entire hose segment 121 is the bellows segment 123, which has better deformation properties and better force release.

In the cooling system of the battery equipment, the liquid valve is generally made of plastic materials, the liquid valve is provided with a butt joint pipe body (a butt joint pipe orifice), the butt joint pipe body (the butt joint pipe orifice) of the liquid valve is connected with the joint 100 through screw locking, and if the locking torque force is not well controlled in the process of locking the liquid valve, the strength of the liquid valve is exceeded, so that the butt joint pipe body of the liquid valve is broken.

In view of the above, the outer surface or the inner surface of the connection section 122 is provided with threads (not shown), the connection section 122 is provided with a limiting portion 125, and the limiting portion 125 is used for abutting against an end portion of the pipe body in threaded connection. When the liquid valve is locked and attached to the connecting section 122 through threaded connection, the limiting part 125 can be abutted against the end part of the butt joint pipe body of the liquid valve and bear a certain acting force, so that the bearable torque of the butt joint pipe body of the liquid valve is improved, and the risk that the thread position of the liquid valve is broken due to overlarge torque is reduced or avoided.

In this embodiment, the inner surface of the connecting section 122 is provided with threads, while the outer surface of the butt joint pipe body of the liquid valve is provided with threads, and the limiting portion 125 is located on the inner surface of the connecting section 122. It will be appreciated that in other embodiments, threads may be provided on the outer surface of the connection section 122, the stop 125 being provided on the outer surface of the connection section 122 and threads on the nipple of the fluid valve being provided on the inner surface.

In order to improve the tightness of the connection between the connection section 122 and the butt joint pipe body of the liquid valve, the joint 100 further includes a sealing ring 130, where the sealing ring 130 is disposed on the limiting portion 125 and is pressed between the limiting portion 125 and the end portion of the butt joint pipe body, so as to implement butt joint sealing. Meanwhile, the sealing ring 130 can bear the acting force when the locking torque of the liquid valve is larger, and has a certain buffering function, so that the torque bearable by the butt joint pipe body of the liquid valve is further improved. Moreover, the threaded opening of the liquid valve will have a certain deformation of the hose section 121 when the locking torque is greater, which partial deformation counteracts the abutment between the end of the connecting section 122 and the locking portion of the liquid valve and reduces the risk of breakage due to increased torque. It should be noted that, in other embodiments, the sealing ring 130 may be disposed on the inner side of the connection section 122, and pressed between the inner side of the connection section 122 and the outer side of the butt-joint pipe body, so that the sealing connection between the two may be achieved.

Further, the limiting portion 125 is provided with a mounting ring groove 126, and the sealing ring 130 is disposed in the mounting ring groove 126, so that the sealing ring 130 is convenient to mount and is prevented from falling off from the limiting portion 125.

In this embodiment, the main body 110 includes a main body 111 and a connecting portion 112, the main body 111 is provided with a connecting through hole 113, and the connecting portion 112 is disposed on a wall of the connecting through hole 113. The connection portion 112 is hermetically connected to one end of the connection pipe body 120 such that at least a portion of the outer surface of the connection pipe body 120 is spaced apart from the wall of the connection through hole 113. By providing the space 106 between at least part of the outer surface of the connecting pipe 120 and the wall of the connecting through hole 113, a reserved space is provided for bending deformation of the hose portion of the connecting pipe 120, and the situation that the hose portion is nested on the wall of the connecting through hole 113 and cannot be bent to cause leakage force failure is avoided.

In this embodiment, at least part of the hose section 121 of the connecting tube body 120 is located in the connecting through-hole 113, wherein the straight tube section 124 of the hose section 121 is located in the connecting through-hole 113 and the bellows section 123 of the hose section 121 is located outside the connecting through-hole 113. It will be appreciated that in other embodiments, bellows segment 123 of tube segment 121 may also be located within connection throughbore 113 such that the entire tube segment 121 is located within connection throughbore 113.

Further, the connection part 112 has a ring shape, and an inner circumferential surface of the connection part 112 is connected with an outer circumferential surface of one end of the connection pipe 120, thereby improving sealability and stability of the connection. In other embodiments, one end of the connecting tube 120 may be connected to an end surface of the connecting portion 112, which may be achieved by welding or bonding, and the shape of the connecting portion 112 is not limited to a ring body, so long as the connecting tube can be connected to one end of the connecting tube 120 in a sealing manner.

In this embodiment, the main body 110 is a metal block, and the connecting portion 112 is connected to one end of the connecting tube 120 by welding, which may be, but not limited to, soldering, spot welding, or the like.

Further, the connecting portion 112 is disposed at one end of the connecting through hole 113, so that one end of the connecting pipe 120 forms another interface 104, i.e. one end of the connecting pipe 120 is disposed corresponding to one end of the connecting through hole 113, thereby facilitating welding, reducing welding difficulty and improving welding effect; meanwhile, most pipe sections of the connecting pipe body 120 are located in the connecting through hole 113, so that the length of the joint 100 is reduced, and the occupation of space is reduced. Wherein the entire communication flow passage 102 of the joint 100 is formed in the connection pipe body 120. It should be noted that, in other embodiments, the connection portion 112 may be disposed between two ends of the connection through hole 113, and another interface 104 is formed on the body portion 111, and a portion of the communication flow channel 102 is formed in the body portion 111; or one end of the connection pipe body 120 may be welded to the other end of the connection through hole 113, since the entire connection pipe body 120 is substantially exposed to the main body 110 without considering a reserved space, and without providing the connection part 112.

Referring to fig. 5, from another point of view, the main body 110 is formed with a connection part 112 by providing a stepped through hole 114, in other words, the main body 110 is provided with a small hole 115 and a large hole 116 therein, an outer surface of one end of the connection pipe 120 is hermetically connected with a wall of the small hole 115, and the other end of the connection pipe 120 extends out of the large hole 116. Further, one end of the connection pipe 120 is disposed corresponding to the outer end of the small hole 115, so that one end of the connection pipe 120 forms the other interface 104. It should be noted that, in other embodiments, other interfaces 104 may be provided on the connector 100, and the other interfaces 104 may be used to connect with meters, sensors, etc. to monitor the fluid passing therethrough.

Referring to fig. 6 and 7, fig. 6 is a schematic structural view of a pipeline assembly according to an embodiment of the present application, fig. 7 is a sectional view of the pipeline assembly according to fig. 6, and an embodiment of the present application provides a pipeline assembly 200, including a connector 210 and a connector 100, wherein the connector 210 is connected to the other end of the connecting tube 120 of the connector 100. The specific structure of the joint 100 refers to the above embodiment, and since the pipeline assembly 200 of this embodiment adopts all the technical solutions of all the embodiments, the joint also has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

In this embodiment, the communicating vessel 210 is a liquid valve, specifically a two-way stop valve, which is made of plastic material and can control the two-way flow of the cooling medium, and when the liquid valve is separated from other pipelines, the cooling medium in the liquid cooling plate can be prevented from flowing out of the liquid valve. It should be noted that, in other embodiments, the connector 210 may be a pipeline, other valve, or other type of joint.

In this embodiment, one interface 104 of the connector 100 is used for communicating with a liquid inlet or a liquid outlet of the liquid cooling plate, the other interface 104 is used for communicating with a liquid valve, the liquid valve is communicated with other pipelines of the cooling system, and a cooling medium of the cooling system can enter a cooling flow passage in the liquid cooling plate through the liquid valve and the connector 100 communicated with the liquid inlet, and finally flows back through the connector 100 and the liquid valve communicated with the liquid outlet, so that a cooling cycle is completed. It will be appreciated that in other embodiments, other lines of the cooling system may be in direct communication with the interface 104 without the need for a liquid valve.

In this embodiment, the connector 210 includes a butt joint pipe 212, the butt joint pipe 212 is also provided with threads corresponding to the threads on the connection section 122 of the joint 100, the butt joint pipe 212 is provided with a locking portion 214, and the butt joint pipe 212 is in threaded connection with the connection section 122. The end of the connection pipe 212 abuts against the stopper 125, and the end of the connection section 122 abuts against the locking portion 214. After the butt joint pipe 212 is locked, the end part of the butt joint pipe 212 extrudes the limiting part 125, the end part of the connecting section 122 extrudes the locking part 214, and the end surface of the limiting part 125 and the end surface of the locking part 214 are stressed simultaneously, when the locking torque is larger, the end surface of the limiting part 125 and the end surface of the locking part 214 bear more acting force simultaneously, the bearable torque is greatly improved, the breaking torque is theoretically improved by more than 1.5 times, and the risk that the thread position of the butt joint pipe 212 is broken due to overlarge torque is reduced or avoided. The length of the connecting section 122 may be adjusted according to the length between the end face of the end of the butt joint pipe 212 and the end face of the locking portion 214, so that the length between the end face of the end of the butt joint pipe 212 and the end face of the locking portion 214 is consistent with the length between the end face of the limiting portion 125 of the connecting section 122 and the end face of the end of the connecting section 122.

In this embodiment, the sealing ring 130 can improve the tightness of the threaded locking between the connecting section 122 and the butt joint pipe 212, and reduce the risk of leakage. When the butt joint pipe 212 is locked, after the sealing ring 130 is compressed, the end face of the butt joint pipe 212 props against the limiting part 125, and the sealing ring 130 can bear certain pressure and has certain buffering function, so that the bearable torque of the butt joint pipe 212 is further improved. Moreover, the threaded mouth of the docking tube 212 may have a certain deformation of the hose segment 121 when the locking torque is greater, which may counteract the abutment between the end of the connection segment 122 and the locking portion 214 and reduce the risk of breakage due to increased torque. It will be appreciated that the seal 130 may be provided on the sides to provide a side seal, as well as reduce the risk of leakage.
