Description

Technical Field

[0001] This application relates to the technical field of pipeline connection, and in particular to a connection connector and a battery pack. Background Technology

[0002] Connecting joints are mainly used as communication structures between mating joints and connecting pipes. A connecting joint typically consists of a connecting body and a locking spring. The connection is achieved through the self-locking of the locking spring and the connecting body. During disassembly, a disassembly tool is usually inserted and applied to the mating surface of the locking spring and the connecting body to release the self-locking mechanism.

[0003] However, the main body of existing connectors is generally set as a fixed structure. In narrow spaces or complex working conditions, the disassembly tool is affected by the surrounding components and cannot be directly inserted into the assembly position surface or there is a deviation in the disassembly angle. This requires the disassembly of its adjacent components before it can be operated, which increases maintenance costs and is prone to structural damage during disassembly, resulting in a poor user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a connection joint that is easy to disassemble, reduces maintenance costs, and is less likely to cause structural damage during disassembly.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A connecting connector for connecting and communicating a mating joint and a connecting pipe, the connecting connector comprising:

[0007] A connecting body for insertion and mating with the mating joint in a first direction;

[0008] A locking spring is inserted into the connecting body in a second direction and detachably connected to the connecting body for locking the mating joint inserted into the connecting body.

[0009] A connector tube, pivotally connected to the connecting body, is used to connect the connecting tube;

[0010] The connecting body can drive the locking spring to rotate relative to the connector tube, thereby changing the position of the locking spring.

[0011] Understandably, this application achieves non-destructive disassembly by configuring a connecting body and a connector tube. The connecting body rotates the locking spring relative to the connector tube, changing the position of the locking spring and aligning it with the connecting body at an angle where a disassembly tool can easily insert. This allows for operation without disassembling adjacent components, reducing maintenance costs for the connector and connector tube, and avoiding disassembly angle deviations that could damage adjacent components or the connector itself, thus improving the user experience of the connector.

[0012] In one embodiment, the connector tube is capable of being inserted into the connecting body, and the connecting body abuts and limits the connector tube in the first direction.

[0013] It is understandable that by setting a limit on the connection between the main body and the connector pipe in the first direction, stable assembly of the two can be achieved.

[0014] In one embodiment, a retaining rib is formed on the connector tube, and a boss is formed on the connecting body;

[0015] In the first direction, a positional interference is formed between the baffle and the boss, which is used to limit the connector tube to the connecting body.

[0016] It is understandable that the positional interference between the retaining rib and the boss allows them to rotate relative to each other while being stably assembled, so that the connecting body can drive the locking spring to rotate relative to the connector tube, adjusting the angle between the locking spring and the assembly surface of the connecting body relative to the connector tube, thereby facilitating disassembly and maintenance.

[0017] In one embodiment, the retaining rib is ring-shaped;

[0018] The number of protrusions is configured to be multiple, and the multiple protrusions are arranged at intervals along the circumferential direction of the connecting body.

[0019] Understandably, the ring-shaped baffle allows the connecting body to rotate nearly 360° relative to the connector tube, making the connector suitable for assembly and disassembly conditions that require large angle adjustments. Furthermore, the multiple bosses not only increase the limiting stability between the connecting body and the connector tube, but also, in conjunction with the ring-shaped baffle, allow the connector to drive the locking spring to rotate at a large angle relative to the connector tube, thus increasing the applicable scenarios for the connector.

[0020] In one embodiment, the plurality of the bosses are arranged symmetrically in the second direction.

[0021] In one embodiment, a first guide slope is formed on the baffle, and a second guide slope is formed on the boss. The baffle can push the second guide slope through the first guide slope to guide the baffle through the boss and to make the baffle and the boss abut and limit each other in the first direction.

[0022] Understandably, the design of the first and second guide ramps can guide the retaining ribs through the boss, improving the accuracy and convenience of assembling the connecting body and the connector pipe.

[0023] In one embodiment, an annular protrusion is further formed on the connecting body, the annular protrusion being correspondingly disposed with the boss, and the boss being disposed on the inner circumferential surface of the corresponding annular protrusion;

[0024] The annular convex plate can undergo elastic deformation under the action of the corresponding protrusion.

[0025] Understandably, the annular convex plate undergoes elastic deformation under the action of the corresponding boss, so as to facilitate the assembly and connection of the connecting body and the connector pipe, avoid damage caused by the forced contact between the boss and the retaining rib during the assembly or disassembly of the connecting body and the connector pipe, and improve the service life of the connecting joint.

[0026] In one embodiment, the annular protrusion is provided with a through groove, which is located on the front side of the protrusion in the first direction.

[0027] Understandably, the through groove design makes the annular convex plate more prone to elastic deformation, reducing structural damage during assembly and disassembly of the connecting body and the connector pipe, and further improving the service life of the connecting joint.

[0028] In one embodiment, the connecting body also has an abutment surface, the locking spring has an unlocking part, the unlocking part is disposed on the outer side of the abutment surface in the second direction, and an unlocking chamber is enclosed between the unlocking part and the abutment surface, the unlocking chamber being used for inserting an unlocking rod.

[0029] This application also provides the following technical solutions:

[0030] A battery pack including the connector described in any of the above embodiments.

[0031] Compared to existing technologies, the aforementioned connector and battery pack, by configuring a connecting body and a connector tube, allows the connecting body to rotate a locking spring relative to the connector tube, changing the position of the locking spring. This rotates the mounting surface of the locking spring and the connecting body to an angle where disassembly tools can easily insert, thus achieving damage-free disassembly. This allows operation without disassembling adjacent components, reducing maintenance costs for the connector and connector tube, and avoiding disassembly angle deviations that could damage adjacent components or the connector itself, thereby improving the user experience of the connector.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0045] Please see Figures 1 to 5 This application provides a connecting joint 100, which is used to connect and communicate a mating joint and a connecting pipe. The main purpose is to facilitate the disassembly and removal of the joint from the connecting joint 100 through structural design, so as to facilitate later maintenance and replacement. This avoids structural damage caused by deviation of the disassembly angle when space is narrow or working conditions are complex, or increased maintenance costs caused by disassembling adjacent components.

[0046] Specifically, the connecting joint 100 includes a connecting body 10, a locking spring 20, and a connecting tube 30. The connecting body is used to insert and mate with the mating joint in a first direction. The locking spring 20 can be inserted into the connecting body 10 in a second direction and is detachably connected to the connecting body 10 to lock the mating joint inserted into the connecting body 10. The connecting tube 30 is pivotally connected to the connecting body 10 and is used to connect the connecting tube. The connecting body 10 can drive the locking spring 20 to rotate relative to the connecting tube 30 to change the position of the locking spring 20.

[0047] It should be explained that the existing connector 100, as described in Chinese Patent Publication No. CN115493011B, mainly achieves locking of the connector and communication between the connector and the connector tube through the insertion and engagement of the locking spring 20 and the connecting body 10. When disassembling the connector, a tool needs to be inserted and applied to the assembly surface of the locking spring 20 and the connecting body 10 to pry it open, allowing the connector to be removed independently. In this type of connector 100, the connecting body 10 is a one-piece fixed structure. In narrow or complex working conditions, the position of the assembly surface of the locking spring 20 and the connecting body 10 may not be convenient for inserting a disassembly tool. Generally, it is necessary to disassemble adjacent components before operation, resulting in high maintenance costs. Furthermore, if forced insertion is performed when the disassembly angle is off, it can easily damage the connecting body 10, the locking spring 20, or other components. Therefore, this application achieves non-destructive disassembly by configuring a connecting body 10 and a connector tube 30, and enabling the connecting body 10 to rotate the locking spring 20 relative to the connector tube 30, thereby changing the position of the locking spring 20 and rotating the mounting surface of the locking spring 20 with the connecting body to an angle position where a disassembly tool can easily insert. In this way, operation can be performed without disassembling adjacent components, reducing the maintenance cost of the connector and connecting joint 100, and avoiding disassembly angle deviations, thus preventing damage to adjacent components or the connector itself, and improving the user experience of the connecting joint 100.

[0048] Here, the first direction is the axial direction of the connecting body 10, and the second direction is the circumferential direction of the connecting body 10.

[0049] In one embodiment, the connecting body 10 is manufactured using a one-piece injection molding process. It is understood that the one-piece molding process reduces the connection structures between the various components on the connecting body 10, increases the structural stability of the connecting body 10, and improves production efficiency while reducing production costs.

[0050] like Figures 1 to 3 As shown, the connecting body 10 can be inserted and mated with the connector tube 30, and the connecting body 10 abuts and limits the connection with the connector tube 30 in a first direction. In this way, a stable assembly of the two can be achieved.

[0051] Furthermore, a boss 11 is formed on the connecting body 10, and a retaining rib 31 is formed on the connector tube 30. In the first direction, a positional interference is formed between the boss 11 and the retaining rib 31 to limit the connector tube 30 to the connecting body 10. In this way, through the positional interference between the boss 11 and the retaining rib 31, they can rotate relative to each other while being stably assembled, so that the connecting body 10 can drive the locking spring 20 to rotate relative to the connector tube, adjusting the angle between the assembly position surface of the locking spring 20 and the connecting body 10 and the connector tube 30, thereby facilitating disassembly and maintenance.

[0052] In one embodiment, the number of bosses 11 is configured to be multiple, and the multiple bosses 11 are arranged at intervals along the circumferential direction of the connecting body 10. In this way, the limiting stability between the connecting body 10 and the connector tube 30 can be increased.

[0053] Here, the number of bosses 11 can be configured as two, four, or six. Of course, this is not a limitation; the number of bosses 11 can be determined according to the actual situation. In this embodiment, the number of bosses 11 is configured as four.

[0054] Furthermore, the multiple protrusions 11 are arranged symmetrically in the second direction.

[0055] like Figure 4 and Figure 5 As shown, a second guide slope 111 is formed on the boss 11, and a first guide slope 311 is formed on the baffle 31. The baffle 31 can push the second guide slope 111 through the first guide slope 311 to guide the baffle 31 through the boss 11 and to make the baffle 31 abut and limit the boss 11 in a first direction. It can be understood that the setting of the first guide slope 311 and the second guide slope 111 can guide the baffle 31 through the boss 11, improving the accuracy and convenience of assembling the connecting body 10 and the connector tube 30.

[0056] Furthermore, an annular protrusion 12 is formed on the connecting body 10, and the annular protrusion 12 is correspondingly provided with a boss 11, with the boss 11 located on the inner circumferential surface 121 of the corresponding annular protrusion 12; wherein, the annular protrusion 12 can undergo elastic deformation under the action of the corresponding boss 11. It can be understood that the elastic deformation of the annular protrusion 12 under the action of the corresponding boss 11 facilitates the assembly and connection of the connecting body 10 and the connector pipe 30, avoids damage from the forced contact between the boss 11 and the retaining rib 31 during the assembly or disassembly of the connecting body 10 and the connector pipe 30, and improves the service life of the connecting joint 100.

[0057] In one embodiment, a through groove 122 is provided on the annular convex plate 12, and the through groove 122 is located on the front side of the protrusion 11 in the first direction. The through groove 122 makes the annular convex plate 12 more prone to elastic deformation, reduces structural damage during assembly and disassembly between the connecting body 10 and the connector tube 30, and further improves the service life of the connecting connector 100.

[0058] In this embodiment, please refer to Figures 2 to 5 The connecting body 10 also has an abutment surface 13, the locking spring 20 has an unlocking part 21, the unlocking part 21 is disposed on the outer side of the abutment surface 13 in the second direction, and an unlocking chamber 22 is enclosed between the unlocking part 21 and the abutment surface 13, the unlocking chamber 22 is used for the insertion of the unlocking rod.

[0059] Here, the unlocking chamber 22 corresponds to the assembly surface of the locking spring 20 and the connecting body 10, and the unlocking rod corresponds to the disassembly tool. Of course, the disassembly tool is not limited to the unlocking rod; it can also be a pry bar or other tools capable of disassembly.

[0060] Please continue to refer to this. Figure 2 and Figure 5 The retaining rib 31 is arranged in a ring shape. It can be understood that the ring shape of the retaining rib allows the connecting body 10 to rotate nearly 360° relative to the connector tube, so that the connecting connector 100 can be used for assembly and disassembly conditions that require large angle adjustments.

[0061] Here, the connector tube 30 is a one-piece injection molded structure. This reduces the number of connecting structures between the various components on the connector tube 30, increases the structural stability of the connector tube 30, improves production efficiency, and reduces production costs.

[0062] This application also provides the following technical solutions:

[0063] A battery pack includes the connector 100 described in any of the above embodiments.

[0064] It is understood that the connector 100 in this application is suitable for connecting the mating connector and the connecting pipe in the battery pack cooling system. By optimizing the structure of the connector 100, the maintenance of the battery pack is made simpler, structural damage during maintenance and disassembly is avoided, and the service life of the battery pack is extended.

[0065] In this application, the connecting joint 100 is rotatably connected to the connecting body 10 and the connecting tube 30, so that the circumferential position of the locking spring 20 relative to the connecting tube 30 can change. This allows it to adapt to the connection and disassembly of the mating joint and connecting tube at various angles in the cooling system of the battery pack. While ensuring the connection stability between the mating joint and the connecting tube, it also facilitates the disassembly and maintenance of the battery pack.

[0066] In one embodiment, the connector 100 is made of polyhexamethylene adipamide (PA66). It is understood that this material has good aging resistance, chemical resistance, and solvent resistance, which can extend the service life of the connector 100.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
