[0004] The connector assembly, battery device and electrical equipment provided in this application are intended to solve the problem of poor sealing performance of the connector assembly and easy coolant leakage.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: to provide a connector assembly, including: a connecting socket, configured to be connected to a heat exchanger; a connecting tube, sleeved on the connecting socket and configured to be connected to an infusion tube; a sealing member, including a sealing body and a first sealing portion and a second sealing portion formed on the sealing body; at least a portion of the sealing body is arranged between the connecting socket and the connecting tube; the first sealing portion is arranged between the connecting socket and the connecting tube along a first direction; the second sealing portion is arranged between the connecting socket and the connecting tube along a second direction; wherein the first direction intersects with the second direction.

[0006] The connector assembly, by providing a first sealing portion and a second sealing portion between the connection socket and the connection tube, seals the gap between the connection socket and the connection tube in two different directions, thereby improving the sealing reliability between the connection socket and the connection tube and reducing the risk of coolant leakage. At the same time, the connector assembly uses different parts of the same seal to seal the gap between the connection socket and the connection tube in different directions. Compared with the scheme in which the connector assembly seals the gap between the connection socket and the connection tube in different directions using two sealing rings, the number of parts is reduced, the rapid assembly of the connector assembly is facilitated, and the risk of displacement of the first sealing portion and the second sealing portion relative to the sealing body and the risk of coolant leakage caused by the gap formed by the assembly of multiple parts are reduced.

[0007] In one embodiment, the connecting socket has a first end and a second end, and the first end of the connecting socket is configured to be connected to the heat exchange member; the connecting pipe includes a tube body and a stopper; the tube body is sleeved on the connecting socket; the stopper is connected to the tube body and abuts against the end surface of the second end of the connecting socket; wherein the first sealing portion is clamped between the connecting socket and the tube body along the first direction; and the second sealing portion is clamped between the end surface of the second end of the connecting socket and the stopper along the second direction.

[0008] In the above scheme, the first sealing portion seals the gap between the connecting socket and the connecting tube along the axial direction of the connecting socket, and the second sealing portion seals the gap between the connecting socket and the connecting tube along the radial direction of the connecting socket, which effectively improves the sealing reliability between the connecting socket and the connecting tube.

[0010] The above scheme can further seal the gap between the connecting socket and the connecting tube along the axial direction of the connecting socket through the sleeve portion; and seal the gap between the connecting socket and the connecting tube along the radial direction of the connecting socket through the abutment portion, so that the sealing performance between the connecting socket and the connecting tube is better.

[0011] In one embodiment, there are multiple first sealing parts, and the multiple first sealing parts are spaced apart along the axial direction of the sleeve part; and / or there are multiple second sealing parts, and the multiple second sealing parts are spaced apart along the direction of the abutment part away from the sleeve part.

[0012] The above scheme can perform multiple sealing on the gap between the connecting socket and the connecting tube along the axial direction of the connecting socket by using multiple first sealing parts; and can also perform multiple sealing on the gap between the connecting socket and the connecting tube along the radial direction of the connecting socket by using multiple second sealing parts; so as to further increase the sealing reliability between the connecting socket and the connecting tube.

[0014] The above scheme, by making the first sealing part and / or the second sealing part in a closed loop, can seal each position between the connection socket and the connection pipe along the circumferential direction of the sealing body through the first sealing part and / or the second sealing part, so as to improve the sealing reliability and reduce the risk of cooling liquid leakage. At the same time, by making the first sealing part a first flange formed on the sleeve part and the second sealing part a second flange formed on the abutment part, not only can the risk of displacement of the first sealing part and the second sealing part relative to the sealing body be reduced; and in the process of preparing the sealing part, the sealing body and the first sealing part and the second sealing part can be formed synchronously, which can simplify the process and save costs.

[0015] In one embodiment, the tube body has a first groove on one side surface facing the connecting socket; the seal also includes a first limiting rib provided on the sleeve portion, and the first limiting rib is embedded in the first groove; and / or the stop portion has a second groove on one side surface facing the connecting socket; the seal also includes a second limiting rib provided on the abutting portion, and the second limiting rib is embedded in the second groove.

[0019] In one embodiment, the first sealing portion and / or the second sealing portion is arranged on a side surface of the sealing body facing away from the connecting pipe.

[0020] The above scheme, by making the first sealing part and the first limiting rib; and / or the second sealing part and the second limiting rib respectively arranged on both sides of the sealing body, can seal the gap between the sealing body and the connecting socket through the first sealing part and / or the second sealing part, and seal the gap between the sealing body and the connecting pipe through the first limiting rib and the second limiting rib; compared with the scheme in which the first sealing part and the first limiting rib; and / or the second sealing part and the second limiting rib are respectively arranged on the same side of the sealing body, the sealing performance of the sealing member on the gap between the connecting socket and the connecting pipe is better.

[0060] In one embodiment, see Figures 1 to 3 , Figure 1 A schematic diagram of the overall structure of a connector assembly provided in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the connector assembly taken along the line AA; Figure 3 for Figure 1 A schematic diagram of the disassembly of the connector assembly is shown. A connector assembly is provided, which includes a connecting socket 1, a connecting tube 2 and a sealing member 3. The connecting socket 1 is configured to be connected to a heat exchange member. The connecting tube 2 is sleeved on the connecting socket 1, and the connecting tube 2 is configured to be connected to an infusion tube. The sealing member 3 includes a sealing body 31 and a first sealing portion 32 and a second sealing portion 33 formed on the sealing body 31; at least a portion of the sealing body 31 is disposed between the connecting socket 1 and the connecting tube 2; the first sealing portion 32 is disposed between the connecting socket 1 and the connecting tube 2 along a first direction X; the second sealing portion 33 is disposed between the connecting socket 1 and the connecting tube 2 along a second direction Y; wherein the first direction X intersects with the second direction Y.

[0061] The connection socket 1 has a communication hole 10. After the connection socket 1 is connected to the heat exchanger, the communication hole 10 of the connection socket 1 is arranged corresponding to the first port or the second port of the heat exchanger to communicate with the liquid guide channel of the heat exchanger. The connection socket 1 can be connected to the heat exchanger by welding. Of course, the connection socket 1 can also be connected to the heat exchanger by fixing parts such as screws and studs.

[0062] As an example, the connecting socket 1 includes a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 is configured to be connected to a heat exchange member. The second connecting portion 12 is connected to a side surface of the first connecting portion 11 and extends in a direction away from the first connecting portion 11. In particular, along the axial direction Y of the connecting socket 1, the size of the second connecting portion 12 is much larger than the size of the first connecting portion 11; for example, along the axial direction Y of the connecting socket 1, the ratio of the size of the second connecting portion 12 to the size of the first connecting portion 11 is not less than 3. The connecting hole 10 passes through the first connecting portion 11 and the second connecting portion 12 along the axial direction Y of the connecting socket 1. In particular, the first connecting portion 11 and the second connecting portion 12 can be integrally formed to enhance the strength of the connecting socket 1 itself.

[0063] In this example, the connecting tube 2 is sleeved inside the connecting socket 1 from the end of the second connecting portion 12 away from the first connecting portion 11, and the following embodiments of the present application take this as an example. Of course, the connecting tube 2 can also be sleeved outside the connecting socket 1 from the end of the second connecting portion 12 away from the first connecting portion 11. The connecting tube 2 can be a curved tube to adjust the connection direction of the connecting tube 2 and the infusion tube.

[0064] The infusion tube can be any tubular structure that can transport liquid or gas, which can be a soft tube or a hard tube. The soft tube and the hard tube are two different pipe materials, which differ in material, use, advantages and disadvantages. For example, the soft tube is usually made of multiple layers of materials, such as polyvinyl chloride (PVC), rubber, etc., and is flexible. The hard tube is usually made of a single material, such as copper pipe, iron pipe, aluminum pipe, etc.

[0065] Combination Figures 2 to 5 , Figure 4 A schematic diagram of the overall structure of a seal provided in one embodiment of the present application; Figure 5 for Figure 4 The AA section view of the seal shown in the figure; the sealing body 31 is clamped between the connection socket 1 and the connection pipe 2, and is used to seal the connection gap between the connection socket 1 and the connection pipe 2. The first sealing portion 32 is provided on the side surface of the sealing body 31 facing the connection socket 1 or the side surface facing the connection pipe 2, so as to seal the gap between the connection socket 1 and the connection pipe 2 along the axial direction Y of the connection socket 1. The second sealing portion 33 can also be provided on the side surface of the sealing body 31 facing the connection socket 1 or the side surface facing the connection pipe 2, so as to seal the gap between the connection socket 1 and the connection pipe 2 along another direction different from the axial direction Y of the connection socket 1, thereby improving the sealing reliability of the seal 3.

[0066] The sealing body 31, the first sealing part 32 and the second sealing part 33 are all elastically compressed between the connection socket 1 and the connection tube 2 to better seal the gap between the connection socket 1 and the connection tube 2. The sealing body 31, the first sealing part 32 and the second sealing part 33 can be integrally formed; the materials of the three can be the same; for example, the materials of the three can be elastic materials such as plastic and rubber.

[0067] Among them, the first direction X can be perpendicular to the axial direction Y of the connecting socket 1; the second direction Y can be parallel to the axial direction Y of the connecting socket 1, so as to seal the connecting socket 1 and the connecting pipe 2 from both the axial and radial directions through the first sealing portion 32 and the second sealing portion 33, thereby effectively improving the sealing reliability of the seal 3 on the gap between the connecting socket 1 and the connecting pipe 2.

[0068] The connector assembly provided in this embodiment provides a first sealing portion 32 and a second sealing portion 33 between the connection socket 1 and the connection tube 2 to seal the gap between the connection socket 1 and the connection tube 2 in two different directions, thereby improving the sealing reliability between the connection socket 1 and the connection tube 2 and reducing the risk of coolant leakage. At the same time, the connector assembly uses different parts of the same seal 3 to seal the gap between the connection socket 1 and the connection tube 2 in different directions. Compared with the solution in which the connector assembly seals the gap between the connection socket 1 and the connection tube 2 in different directions using two sealing rings, the number of parts is reduced, the rapid assembly of the connector assembly is facilitated, and the risk of displacement of the first sealing portion 32 and the second sealing portion 33 relative to the sealing body 31 and the risk of coolant leakage caused by the gap formed by the assembly of multiple parts are reduced.

[0069] In one embodiment, in combination Figure 2 and Figure 6 , Figure 6 The overall structural diagram of the connecting pipe provided in one embodiment of the present application; the connecting socket 1 has a first end and a second end, and the first end of the connecting socket 1 is configured to be connected to the heat exchanger. The connecting pipe 2 includes a tube body 21 and a stopper 22; the tube body 21 is sleeved on the connecting socket 1. The stopper 22 is connected to the tube body 21 and abuts against the end face of the second end of the connecting socket 1. Among them, the first sealing portion 32 is clamped between the connecting socket 1 and the tube body 21 along the first direction X; the second sealing portion 33 is clamped between the end face of the second end of the connecting socket 1 and the stopper 22 along the second direction Y.

[0070] As an example, along the axial direction Y of the connection socket 1 , an end of the first connection portion 11 away from the second connection portion 12 serves as the first end of the connection socket 1 , and an end of the second connection portion 12 away from the first connection portion 11 serves as the second end of the connection socket 1 .

[0071] Combination Figure 2, the tube body 21 can be a curved tube, and the tube body 21 is sleeved in the second connection part 12 of the connecting socket 1. The stopper 22 is arranged on the outer wall surface of the side wall of the tube body 21; and the stopper 22 can be arranged along the circumferential direction of the tube body 21. After the connecting tube 2 is connected to the connecting socket 1, the stopper 22 abuts against the side surface of the second connection part 12 away from the first connection part 11, and the stopper 22 abuts against each position of the second connection part 12 along its circumferential direction. Among them, the outer diameter of the connecting tube 2 corresponding to the position where the stopper 22 is located can be larger than the outer diameter of the second connection part 12, and smaller than the outer diameter of the first connection part 11, so as to facilitate the disassembly of the connecting tube 2 and the connecting socket 1. In this embodiment, the connecting tube 2 can limit the depth of the connecting tube 2 inserted into the connecting socket 1 by setting the stopper 22.

[0072] In this embodiment, the first sealing portion 32 can seal the gap between the inner wall surface of the connection socket 1 and the connection tube 2 to reduce the risk that the gap between the inner wall surface of the connection socket 1 and the connection tube 2 becomes larger due to the force on the connector assembly, resulting in the coolant leaking from the gap between the inner wall surface of the connection socket 1 and the connection tube 2. At the same time, the second sealing portion 33 can seal the gap between the end surface of the connection socket 1 and the connection tube 2 to reduce the risk that the end surface of the second end of the connection socket 1 and the connection tube 2 are not effectively abutted, or the gap between the end surface of the second end of the connection socket 1 and the connection tube 2 becomes larger due to the force on the connector assembly, resulting in the coolant leaking from the gap between the end surface of the connection socket 1 and the connection tube 2, thereby effectively improving the sealing reliability between the connection socket 1 and the connection tube 2.

[0073] In one embodiment, in combination Figures 2 to 4 The sealing body 31 includes a sleeve portion 311 and a contact portion 312. The sleeve portion 311 is sleeved on the tube body 21, and the first sealing portion 32 is formed on the sleeve portion 311; the contact portion 312 is connected to the sleeve portion 311 along the circumferential direction of the sleeve portion 311, and is located between the stop portion 22 and the connecting socket 1, and the second sealing portion 33 is formed on the contact portion 312.

[0074] The sleeve portion 311 is sleeved on the outer side wall of the side wall of the tube body 21, and the first sealing portion 32 is formed on a side surface of the sleeve portion 311 away from the tube body 21, and the first sealing portion 32 can be in a closed loop along the circumferential direction of the sleeve portion 311. The abutting portion 312 can be connected to one end of the sleeve portion 311 along the axial direction Y of the sealing member 3. The abutting portion 312 is specifically provided on a side surface of the stopper portion 22 facing the connection socket 1, and is clamped between the end surface of the second connection portion 12 away from the first connection portion 11 and the stopper portion 22.

And / or there are multiple second sealing portions 33, which are spaced apart along the direction in which the abutting portion 312 is away from the sleeve portion 311.

[0078] As an example, the number of the first sealing parts 32 is multiple, and the multiple first sealing parts 32 are spaced apart along the axial direction Y of the sleeve part 311.

And / or the second sealing portion 33 is a second flange formed on the abutting portion 312, the second flange extends along the circumferential direction of the abutting portion 312, and is in a closed loop shape.

[0083] The first flange and the second flange are integrally formed with the sealing body 31 and protrude from the sealing body 31 .

[0084] As an example, the first sealing portion 32 is a first flange formed on the sleeve portion 311; or the second sealing portion 33 is a second flange formed on the abutting portion 312; or the first sealing portion 32 is a first flange formed on the sleeve portion 311, and the second sealing portion 33 is a second flange formed on the abutting portion 312.

[0085] In this embodiment, by making the first sealing part 32 and / or the second sealing part 33 in a closed loop, each position between the connecting socket 1 and the connecting pipe 2 can be sealed along the circumferential direction of the sealing body 31 by the first sealing part 32 and / or the second sealing part 33, so as to improve the sealing reliability and reduce the risk of cooling liquid leakage. At the same time, by making the first sealing part 32 a first flange formed on the sleeve part 311 and the second sealing part 33 a second flange formed on the abutting part 312, not only can the risk of displacement of the first sealing part 32 and the second sealing part 33 relative to the sealing body 31 be reduced; and in the process of preparing the sealing member 3, the sealing body 31 can be formed synchronously with the first sealing part 32 and the second sealing part 33, which can simplify the process and save costs.

[0086] In one embodiment, in combination Figure 5 and Figure 6 The tube body 21 has a first card groove 211 on one side surface facing the connecting socket 1; the sealing member 3 also includes a first limiting rib 34 provided on the sleeve portion 311, and the first limiting rib 34 is embedded in the first card groove 211; and / or the stop portion 22 has a second card groove 221 on one side surface facing the connecting socket 1; the sealing member 3 also includes a second limiting rib 35 provided on the abutting portion 312, and the second limiting rib 35 is embedded in the second card groove 221.

[0087] The first card groove 211 extends along the circumferential direction of the tube body 21. The entire first limiting rib 34 is embedded in the first card groove 211, so that the sealing body 31 is in close contact with the tube body 21, thereby improving the sealing performance between the tube body 21 and the sleeve portion 311. The second card groove 221 extends along the circumferential direction of the stopper portion 22, and the entire second limiting rib 35 is fully embedded in the second card groove 221, so that the sealing body 31 is in close contact with the surface of the stopper portion 22 facing the connection socket 1, thereby improving the sealing performance between the stopper portion 22 and the sealing body 31.

Alternatively, the tube body 21 has a first groove 211 on one side of the surface facing the connection socket 1; the seal 3 also includes a first limiting rib 34 provided on the sleeve portion 311, and the first limiting rib 34 is embedded in the first groove 211; and the stopper 22 has a second groove 221 on one side of the surface facing the connection socket 1; the seal 3 also includes a second limiting rib 35 provided on the abutment portion 312, and the second limiting rib 35 is embedded in the second groove 221.

[0089] In this embodiment, the first limiting rib 34 and the first clamping groove 211 are clamped together to reduce the risk of displacement of the seal 3 relative to the connecting pipe 2 along the axial direction Y of the seal 3 or even falling off the connecting pipe 2. At the same time, the second limiting rib 35 and the second clamping groove 221 are clamped together to reduce the risk of displacement of the seal 3 relative to the connecting pipe 2 along the radial direction of the seal 3.

[0090] In one embodiment, in combination Figure 5 , the first limiting rib 34 is a third flange formed on the sleeve portion 311, and the third flange is in a closed loop along the circumferential direction of the sleeve portion 311. Or the second limiting rib 35 is a fourth flange formed on the abutting portion 312, and the fourth flange is in a closed loop along the circumferential direction of the abutting portion 312. Or the first limiting rib 34 is a third flange formed on the sleeve portion 311, and the third flange is in a closed loop along the circumferential direction of the sleeve portion 311; and the second limiting rib 35 is a fourth flange formed on the abutting portion 312, and the fourth flange is in a closed loop along the circumferential direction of the abutting portion 312.

[0091] The third flange is integrally formed with the sealing body 31, and protrudes toward the inside of the sealing member 3 along the radial direction of the sealing member 3. The fourth flange is integrally formed with the sealing body 31, and protrudes from the abutting portion 312 toward the direction away from the sleeve portion 311 along the axial direction Y of the sealing member 3. The fourth flange is specifically provided at a side edge of the abutting portion 312 away from the sleeve portion 311 along the radial direction of the sealing member 3. It should be noted that the first to fourth flanges involved in the present application can all be understood as the protruding portion of the sealing body 31.

[0092] In this embodiment, combined Figure 6 The first card groove 211 is arranged along the circumferential direction of the tube body 21, and the closed-loop first limiting rib 34 corresponds to the first card groove 211 and is embedded in the first card groove 211 along the extension direction of the first card groove 211, so as to limit the sealing member 3 and the connecting tube 2 along the axial direction Y of the connecting socket 1, and at the same time, play a certain sealing role in the gap between the connecting socket 1 and the connecting tube 2 along the axial direction of the connecting socket 1.

[0093] Similarly, the second slot 221 is also arranged in a circle along the circumferential direction of the stop portion 22, and the closed-loop second limiting rib 35 corresponds to the second slot 221 and is embedded in the second slot 221 along the extension direction of the second slot 221, so as to limit the seal 3 and the connecting tube 2 along the radial direction of the connecting socket 1 while playing a certain sealing role in the gap between the connecting socket 1 and the connecting tube 2 along the radial direction of the connecting socket 1.

[0094] In some examples, the seal 3 can be formed on the connection tube 2 by overmolding. That is, the connection tube 2 is first prepared, and the first card slot 211 and the second card slot 221 are correspondingly formed on the connection tube 2. Then the connection tube 2 is placed in a mold, and the injection molding material is injected to form a first limiting rib 34 in the first card slot 211 and a second limiting rib 35 in the second card slot 221; at the same time, the sealing body 31, the first sealing part 32 and the second sealing part 33 are formed. Finally, the combined structure of the connection tube 2 and the seal 3 is inserted into the connection socket 1 to form a connector assembly.

[0095] As another example, the first limiting rib 34 and the first clamping groove 211, and / or the second limiting rib 35 and the second clamping groove 221 may also be connected by interference fit to achieve a better sealing effect.

[0096] In this embodiment, by making the first limiting rib 34 a third flange formed on the sleeve portion 311, and / or the second limiting rib 35 a fourth flange formed on the abutting portion 312, the sealing body 31 can be formed synchronously with the first limiting rib 34 and the second limiting rib 35 during the preparation of the sealing member 3, which can simplify the process and save costs. At the same time, by making the third flange and / or the fourth flange in a closed loop, the gap between the connecting socket 1 and the connecting pipe 2 can be sealed from the side of the sealing member 3 toward the connecting pipe 2 through the cooperation between the third flange and the first card groove 211, and the cooperation between the fourth flange and the second card groove 221, so as to further improve the sealing reliability of the connector assembly.

[0097] In one embodiment, in combination Figure 2 , the first sealing portion 32 is provided on the side surface of the sealing body 31 away from the connecting pipe 2. Or the second sealing portion 33 is provided on the side surface of the sealing body 31 away from the connecting pipe 2. Or the first sealing portion 32 is provided on the side surface of the sealing body 31 away from the connecting pipe 2, and the second sealing portion 33 is provided on the side surface of the sealing body 31 away from the connecting pipe 2.

[0098] That is, the first sealing portion 32 and the first limiting rib 34 are located on both sides of the sealing body 31 ; and / or the second sealing portion 33 and the second limiting rib 35 are located on both sides of the sealing body 31 .

[0099] In this embodiment, by arranging the first sealing portion 32 and the first limiting rib 34; and / or the second sealing portion 33 and the second limiting rib 35 on both sides of the sealing body 31 respectively, the gap between the sealing body 31 and the connecting socket 1 can be sealed by the first sealing portion 32 and / or the second sealing portion 33, and the gap between the sealing body 31 and the connecting pipe 2 can be sealed by the first limiting rib 34 and the second limiting rib 35; compared with the scheme in which the first sealing portion 32 and the first limiting rib 34; and / or the second sealing portion 33 and the second limiting rib 35 are respectively arranged on the same side of the sealing body 31, the sealing performance of the sealing member 3 on the gap between the connecting socket 1 and the connecting pipe 2 is better.

[0100] In one embodiment, in combination Figure 2 and Figure 3 The connection socket 1 has a communication hole 10, the connection pipe 2 is sleeved in the communication hole 10, and the inner wall surface of the communication hole 10 is provided with a limit groove 13; the outer wall surface of the connection pipe 2 is provided with a clamping groove 212. The connector assembly also includes a limiter 4, which is sleeved on the outer side of the connection pipe 2, and at least part of the limiter 4 along the radial direction is embedded in the limit groove 13, and part of the limiter 4 along the axial direction Y is embedded in the clamping groove 212.

[0101] The limiting groove 13 can be arranged along the circumferential direction of the connecting socket 1. The clamping groove 212 can be arranged along the circumferential direction of the tube body 21. Figure 3 The limiting member 4 is annular and is sleeved on the outside of the tube body 21. The portion of the limiting member 4 along the axial direction Y is bent toward the inside of the tube body 21 in the radial direction of the tube body 21 and embedded in the clamping groove 212 to reduce the risk of relative displacement between the limiting member 4 and the connecting tube 2.

[0102] Furthermore, the portion of the stopper 4 along the radial direction thereof is embedded in the stopper groove 13, so as to fix the relative position between the connecting tube 2 and the connecting socket 1 through the stopper 4. The stopper 4 may be an elastic member, and during the assembly process of the connector assembly, the stopper 4 may be sleeved on the outer side of the tube body 21, and inserted into the connecting hole 10 of the connecting socket 1 together with the tube body 21. During the insertion of the connecting tube 2 into the connecting hole 10, the stopper 4 is elastically compressed, and when the stopper 4 is inserted to the position where the stopper groove 13 is located, the stopper 4 is restored to the initial state under the action of the elastic restoring force, so as to be embedded in the stopper groove 13, thereby fixing the relative position between the connecting tube 2 and the connecting socket 1 along the axial direction Y thereof, and reducing the risk of the connecting tube 2 falling off the connecting socket 1.

[0103] Of course, in some other examples, the stopper 4 can also be pre-set in the stopper groove 13 before the connecting tube 2 is inserted into the communicating hole 10; in this example, the portion of the stopper 4 along the axial direction Y protrudes toward the communicating hole 10. During the process of inserting the connecting tube 2 into the communicating hole 10, the connecting tube 2 squeezes the protruding portion of the stopper 4, and when the protruding portion of the stopper 4 is correspondingly arranged with the clamping groove 212, the protruding portion of the stopper 4 returns to the initial state and is embedded in the clamping groove 212 to fix the relative position of the connecting tube 2 and the connecting socket 1.

[0104] Among them, combined Figure 3 The limiting member 4 may have a notch along its circumferential direction so that the limiting member 4 can be arranged in the limiting groove 13.

[0105] In this embodiment, by partially embedding the limiting member 4 into the limiting groove 13 and partially embedding the limiting member 4 into the clamping groove 212 , the risk of the connecting pipe 2 falling off the connecting socket 1 can be reduced.

[0106] In one embodiment, in combination Figure 2 The outer diameter of the limiting member 4 gradually decreases along the direction in which the connecting pipe 2 is inserted into the communicating hole 10 .

[0107] The outer diameter of the stopper 4 refers to the maximum radial dimension corresponding to the outer wall surface of the side wall of the stopper 4. As an example, the cross-sections of the first connection portion 11, the second connection portion 12, the connecting hole 10, the sleeve portion 311 and the tube body 21 can all be circular. The direction in which the connecting tube 2 is inserted into the connecting hole 10 is also the direction in which the second connection portion 12 faces the first connection portion 11.

[0108] In this embodiment, by gradually reducing the outer diameter of the stopper 4 along the direction in which the connecting pipe 2 is inserted into the communicating hole 10 , it is convenient for the connecting pipe 2 to be inserted into the communicating hole 10 of the connecting socket 1 , thereby facilitating the assembly of the connector assembly.
