Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector. Background Technology

[0002] With the development of the automotive industry, the application of high-voltage, high-current connectors in the new energy sector is becoming increasingly widespread. The electrification trend in the automotive and marine industries is becoming more pronounced, intensifying the demand for high voltage and high current. Electrical components (PDUs, battery boxes, etc.) in electrical connection lines generate significant heat, leading to a growing need for liquid cooling. Cooling of electrical connection lines is typically achieved by setting up cooling channels, with high-voltage connectors and cooling channel connectors connecting different electrical components. However, the connectors for high-voltage lines and cooling channels are usually separate, requiring separate connections, which significantly increases installation difficulty. Utility Model Content

[0003] The main purpose of this invention is to provide a connector that reduces the difficulty of setting up electrical connection lines and cooling flow paths.

[0004] To achieve the above objectives, this utility model proposes a connector, the connector comprising:

[0005] A first connector, the first connector being provided with a first electrical connector and a first cooling head;

[0006] A second connector is provided, comprising a second electrical connector and a second cooling head. The second electrical connector is used to insert and mate with the first electrical connector, and the second cooling head is used to insert and mate with the first cooling head.

[0007] A locking handle is rotatably connected to the first connecting seat. The locking handle is provided with a first locking tooth, and the second connecting seat is provided with a first locking groove.

[0008] Specifically, rotating the locking handle relative to the first connecting seat causes the first locking tooth to engage or disengage from the first locking slot, thereby locking or unlocking the relative positions of the first connecting seat and the second connecting seat.

[0009] In one embodiment, the locking handle includes a gripping part and a locking gear. The gripping part is rotatably connected to the first connecting seat, and the locking gear is connected to the gripping part. The locking gear is arranged around the rotation axis of the gripping part, and the first locking tooth is provided on the periphery of the locking gear.

[0010] In one embodiment, the second connector is provided with a plurality of second locking teeth, which are spaced apart along the insertion and removal direction of the second connector, and a first locking groove is formed between two adjacent second locking teeth.

[0011] In one embodiment, the first locking teeth include a plurality of teeth, which are spaced apart circumferentially along the locking gear; the first locking slots also include a plurality of slots, with each first locking tooth corresponding to one of the first locking slots.

[0012] In one embodiment, the gripping part includes a first segment, a second segment, and a third segment connected at an angle. The first segment has a first connecting end at the end away from the second segment, and the third segment has a second connecting end at the end away from the second segment. The first connecting end and the second connecting end are respectively rotatably connected to both sides of the first connecting seat.

[0013] In one embodiment, the snap-fit ​​gears include two gears, which are respectively arranged around the rotation axis of the first connecting end and the rotation axis of the second connecting end.

[0014] In one embodiment, the first connecting seat is provided with a snap-fit ​​groove, and the locking handle further includes a first elastic member and a snap-fit ​​block. One end of the first elastic member is connected to the grip portion, and the other end of the first elastic member is connected to the snap-fit ​​block. The snap-fit ​​block is used to snap into the snap-fit ​​groove to lock the position of the grip portion.

[0015] In one embodiment, the gripping part is provided with a first limiting groove, the snap-fit ​​block is at least partially limited in the first limiting groove, the bottom of the first limiting groove is provided with a limiting post, the end of the snap-fit ​​block near the limiting post is provided with a second limiting groove, one end of the first elastic member is sleeved on the limiting post, and the other end of the first elastic member is limited in the second limiting groove.

[0016] In one embodiment, the snap-fit ​​block includes a connecting portion, a snap-fit ​​portion, and an abutting portion. The connecting portion is provided with a second limiting groove. The snap-fit ​​portion is located on the end side of the connecting portion away from the opening of the second limiting groove. The snap-fit ​​portion is used to engage with the second limiting groove. The abutting portion is located on the periphery of the connecting portion. The abutting portion is used to abut against the periphery of the snap-fit ​​groove.

[0017] In one embodiment, the second cooling head includes a main body, a second elastic member, and a blocking member. The main body has a cold flow channel and an opening communicating with the cold flow channel. One end of the second elastic member is connected to the main body, and the other end of the second elastic member is connected to the blocking member. The blocking member is disposed in the cold flow channel and is used to block the opening.

[0018] When the first cooling head is inserted into the second cooling head, at least a portion of the first cooling head pushes the blocking member, and the second elastic member deforms to open the opening.

[0019] The technical solution of this utility model involves simultaneously mounting a first electrical connector and a first cooling head on a first connecting base, and simultaneously mounting a second electrical connector and a second cooling head on a second connecting base. The first and second electrical connectors are used to connect cables, and the first and second cooling heads are used to connect cooling pipes. When the first and second connecting bases are connected, the first and second electrical connectors, as well as the first and second cooling heads, can simultaneously insert and engage to achieve simultaneous connection of the electrical connection lines and cooling pipes. A locking handle is also rotatably connected to the first connecting base. After the first and second connecting bases are connected, the locking handle can be rotated to a locked state, causing the first locking tooth on the locking handle to engage with the first locking groove of the second connecting base, thereby locking the positions of the first and second connecting bases and ensuring the reliability of the connection between the electrical connection lines and the cooling flow path. This application, through the connection of the first and second connecting bases and the simultaneous locking of their positions by the locking handle, enables rapid and reliable connection of the electrical connection lines and cooling pipes, greatly reducing the difficulty of setting up the electrical connection lines and cooling pipes.

[0035] Please combine Figures 1 to 8 As shown, this utility model proposes a connector 100, which includes a first connecting seat 1, a second connecting seat 2, and a locking handle 3. The first connecting seat 1 is provided with a first electrical connector 12 and a first cooling head 13; the second connecting seat 2 is provided with a second electrical connector 22 and a second cooling head 23. The second electrical connector 22 is used to insert and cooperate with the first electrical connector 12, and the second cooling head 23 is used to insert and cooperate with the first cooling head 13. The locking handle 3 is rotatably connected to the first connecting seat 1. The locking handle 3 is provided with a first locking tooth 321, and the second connecting seat 2 is provided with a first locking groove 25. Relative to the first connecting seat 1, rotating the locking handle 3 causes the first locking tooth 321 to engage or disengage from the first locking groove 25, thereby locking or unlocking the relative position of the first connecting seat 1 and the second connecting seat 2.

[0036] In this embodiment, the connector 100 includes a first connector 1 and a second connector 2. The first connector 1 is provided with a first electrical connector 12 and a first cooling head 13. The second connector 2 is provided with a second electrical connector 22 and a second cooling head 23 that match the first electrical connector 12 and the first cooling head 13. The first electrical connector 12 and the second electrical connector 22 can be connected to cables respectively, and the second cooling head 23 and the first cooling head 13 can be connected to cooling pipes 4 respectively. When the first connector 1 and the second connector 2 are connected, the second electrical connector 22 is inserted into the first electrical connector 12, and the second cooling head 23 is inserted into the first cooling head 13, thereby simultaneously realizing the electrical connection of the circuit and the connection of the cooling pipe 4. That is, the connection of the circuit and the cooling pipe 4 can be achieved through the same connector 100, which can effectively reduce the difficulty of setting up the internal wiring and cooling flow path of the vehicle body and improve the installation efficiency. In addition, connector 100 also includes a locking handle 3, which is rotatably connected to the connector male seat. The locking handle 3 is provided with a first locking tooth 321, and the second connector 2 is provided with a first locking groove 25 that mates with the first locking tooth 321. After the first connector 1 and the second connector 2 are inserted into place, the locking handle 3 can be rotated relative to the first connector 1 to make the first locking tooth 321 engage with the first locking groove 25 on the second connector 2, thereby locking the relative position of the first connector 1 and the second connector 2. This effectively prevents loosening due to vibration, ensures the stability of the circuit connection and the connection of the cooling pipe 4, and improves the safety and reliability of the connection.

[0037] Understandably, when it is necessary to disconnect the connection between the first connecting seat 1 and the second connecting seat 2, the locking handle 3 can be rotated again relative to the first connecting seat 1 to disengage the first locking tooth 321 from the first locking groove 25 of the second connecting seat 2, thereby releasing the lock between the first connecting seat 1 and the second connecting seat 2, and then the first connecting seat 1 and the second connecting seat 2 can be separated. This allows for quick disconnection of the first connecting seat 1 and the second connecting seat 2, which is beneficial for the later maintenance of the internal wiring and cooling flow path of the vehicle body. Optionally, the cooling medium flowing in the cooling pipe 4 can be water, oil, etc.

[0038] Optionally, the first electrical connector 12 is a male electrical connector and the second electrical connector 22 is a female electrical connector, or the first electrical connector 12 is a female electrical connector and the second electrical connector 22 is a male electrical connector; similarly, the first cooling head 13 can be a cooling plug and the second cooling head 23 can be a cooling connector, or the first cooling head 13 can be a cooling connector and the second cooling head 23 can be a cooling plug.

[0039] In practical implementation, the first connector 1 includes a first housing 11, with a first electrical connector 12 and a first cooling head 13 spaced apart on the first housing 11. The first electrical connector 12 and the first cooling head 13 can be detachably connected to the first housing 11 via bolts or clips. The second connector 2 includes a second housing 21, with a second electrical connector 22 and a second cooling head 23 spaced apart on the second housing 21. The second electrical connector 22 and the second cooling head 23 can be detachably connected to the first housing 11 via bolts or clips. The detachable arrangement of the first electrical connector 12 and the first cooling head 13, as well as the second electrical connector 22 and the second cooling head 23, facilitates later maintenance and replacement, and allows for the replacement of different models of the first electrical connector 12 and the first cooling head 13, as well as the second electrical connector 22 and the second cooling head 23, thereby improving the adaptability of the connector 100.

[0040] Specifically, the first cooling head 13 is provided with a threaded section and a limiting platform surrounding the threaded section. The first housing 11 is provided with a connecting hole. The threaded section of the first cooling head 13 passes through the connecting hole from one side of the first housing 11 until the limiting platform abuts against the first housing 11. Then, a nut that mates with the threaded section is screwed into the threaded section from the other side of the first housing 11 until the nut abuts against the first housing 11, thereby installing the first cooling head 13 onto the first housing 11. The connection method between the second cooling head 23 and the second housing 21 can refer to the connection method between the first cooling head 13 and the first housing 11, and will not be described in detail here. Optionally, the locking handle 3 can be rotatably connected to the first housing 11 through a shaft hole fit or a bearing or other structure.

[0041] In embodiments of this utility model, such as Figures 4 to 7 As shown, the locking handle 3 includes a gripping part 31 and a locking gear 32. The gripping part 31 is rotatably connected to the first connecting seat 1, and the locking gear 32 is connected to the gripping part 31. The locking gear 32 is arranged around the rotation axis of the gripping part 31, and the periphery of the locking gear 32 is provided with a first locking tooth 321.

[0042] In this embodiment, the locking gear 32 is connected to the gripping part 31. When the gripping part 31 rotates relative to the first connecting seat 1, the locking gear 32 also rotates with the gripping part 31, so as to drive the first locking tooth 321 provided on the periphery of the locking gear 32 to rotate around the rotation axis, so that the first locking tooth 321 engages or disengages from the first slot 25 on the second connecting seat 2, thereby locking or unlocking the relative position of the first connecting seat 1 and the second connecting seat 2.

[0043] Understandably, the engaging gear 32 is arranged around the rotation axis of the gripping part 31. That is, when the gripping part 31 rotates relative to the first connecting seat 1, the engaging gear 32 rotates around the rotation axis of the gripping part 31, and the first locking tooth 321 moves circumferentially along the engaging gear 32 to engage or disengage from the first locking groove 25. By using the gripping part 31 to drive the engaging gear 32 to rotate, the gripping part 31 forms a lever to reduce the force required for the rotation of the engaging gear 32 and reduce the difficulty of engaging the first locking tooth 321 into the first locking groove 25. It should be noted that when the gripping part 31 is rotatably connected to the first connecting seat 1 via a rotating shaft, the rotation axis of the gripping part 31 is the axis of the rotating shaft.

[0044] In actual implementation, the orientation of the opening of the first slot 25 is set at an angle to the insertion and removal directions of the first connecting seat 1 and the second connecting seat 2. Optionally, the orientation of the opening of the first slot 25 is set perpendicular to the insertion and removal directions of the first connecting seat 1 and the second connecting seat 2. When the first connecting seat 1 and the second connecting seat 2 are inserted, the first electrical connector 12 is limited by the second electrical connector 22 on the periphery, and the first cooling head 13 is limited by the second cooling head 23 on the periphery. The first connecting seat 1 and the second connecting seat 2 only have a degree of freedom of movement in the insertion and removal direction. When the first locking tooth 321 is engaged with the opening of the first slot 25, the relative position of the first connecting seat 1 and the second connecting seat 2 can be locked.

[0045] Optionally, in the radial direction of the engaging gear 32, the cross-sectional area of ​​the first locking tooth 321 gradually decreases from the end near the center of the engaging gear 32 to the end away from the center of the engaging gear 32, so that the first locking tooth 321 can engage with the first locking groove 25 as the engaging gear 32 rotates. The first locking tooth 321 may be triangular or trapezoidal in shape, and the shape of the first locking groove 25 matches the shape of the first locking tooth 321 to ensure the stability of the engagement between the first locking tooth 321 and the first locking groove 25.

[0046] Alternatively, the grip 31 and the locking gear 32 can be connected by a structure such as screws or clips.

[0047] In embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the second connector 2 is provided with a plurality of second locking teeth 24, which are spaced apart along the insertion and removal direction of the second connector 2, and a first slot 25 is formed between two adjacent second locking teeth 24.

[0048] In this embodiment, the second locking teeth 24 are arranged at intervals along the insertion and extraction direction of the second connecting seat 2, and two adjacent second locking teeth 24 form the two side walls of the first locking groove 25. After the second connecting seat 2 and the first connecting seat 1 are pre-inserted into place, the second connecting seat 2 and the first connecting seat 1 can be further inserted by utilizing the insertion and engagement of the first locking teeth 321 and the first locking groove 25. During the engagement or disengagement of the first locking teeth 321 and the first locking groove 25, the first locking teeth 321 rotate circumferentially along the locking gear 32 under the drive of the holding part 31, and will first abut against one side wall of the first locking groove 25, and drive the second connecting seat 2 to move along the insertion and extraction direction of the second connecting seat 2. Specifically, when the locking handle 3 is rotated forward relative to the first connecting seat 1 to engage the first locking tooth 321 into the first locking slot 25, the first locking tooth 321 will first abut against the second locking tooth 24 on the side of the first locking slot 25 closest to the first connecting seat 1. As the locking handle 3 rotates, the first locking tooth 321 will push the second locking tooth 24 to move the second connecting seat 2 in the insertion direction, so that the second connecting seat 2 and the first connecting seat 1 are more tightly connected, ensuring the stability of their connection. Conversely, when the locking handle 3 is rotated in the opposite direction relative to the first connecting seat 1 to disengage the first locking tooth 321 from the first locking slot 25, the first locking tooth 321 will first abut against the second locking tooth 24 on the side of the first locking slot 25 away from the first connecting seat 1. As the locking handle 3 rotates, the second locking tooth 24 will push the second locking tooth 24 to move the second connecting seat 2 in the extraction direction, so as to loosen the second connecting seat 2 and the first connecting seat 1, making them easier to separate.

[0049] Understandably, the arrangement of the second locking teeth 24 is similar to that of the rack structure. The locking gear 32 meshes with the rack structure of the second locking teeth 24. The rotation of the locking gear 32 can drive the second locking teeth 24 to move in a straight line, that is, in the insertion and removal direction of the second connecting seat 2.

[0050] Optionally, the edge of the first slot 25 is chamfered to facilitate the insertion of the first tooth 321, effectively reducing the wear of the first tooth 321 and the second tooth 24 during the insertion process, thereby extending the service life of the connector 100.

[0051] In embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the first locking teeth 321 include multiple first locking teeth 321, which are spaced apart along the circumference of the locking gear 32; the first locking groove 25 also includes multiple first locking teeth 321, which are arranged in a one-to-one correspondence with the first locking groove 25.

[0052] In this embodiment, the periphery of the locking gear 32 is provided with multiple first locking teeth 321, arranged along the insertion and removal direction of the second connector 2. After the first connector 1 and the second connector 2 are pre-inserted into place, the locking handle 3 can be rotated relative to the first connector 1 to cause the locking gear 32 to drive the peripheral first locking teeth 321 to rotate. As the locking gear 32 rotates, the multiple first locking teeth 321 can sequentially engage with the corresponding first locking slots 25, so that the first connector 1 and the second connector 2 are further inserted, improving the tightness of the insertion between the first connector 1 and the connector female. When manufacturing the connector 100, the number and length of the first locking teeth 321 and the first locking slots 25 can be set according to the further insertion stroke required for the first connector 1 and the second connector 2.

[0053] Understandably, the first slot 25 is formed by two adjacent second teeth 24, and a second slot 322 is formed between two adjacent first teeth 321. After the locking handle 3 is locked in place, the first teeth 321 are engaged in the first slot 25, and the second teeth 24 on both sides of the first slot 25 are also engaged in the second slot 322 adjacent to the first teeth 321, so as to improve the locking effect of the locking handle 3 on the relative position of the first connecting seat 1 and the second connecting seat 2.

[0054] In embodiments of this utility model, such as Figures 6 to 7 As shown, the gripping part 31 includes a first segment 311, a second segment 312 and a third segment 313 connected at an angle. The first segment 311 has a first connecting end at the end away from the second segment 312, and the third segment 313 has a second connecting end at the end away from the second segment 312. The first connecting end and the second connecting end are respectively rotatably connected to the two sides of the first connecting seat 1.

[0055] In this embodiment, the gripping part 31 is rotatably connected to both sides of the first connecting seat 1 via the first connecting end and the second connecting end, respectively, to ensure the flexibility and stability of the gripping part 31 in rotating relative to the first connecting seat 1. The first segment 311, the second segment 312, and the third segment 313 are connected at an included angle to form a clearance space between the first segment 311, the second segment 312, and the third segment 313, thereby avoiding the first connecting seat 1 during rotation.

[0056] In actual implementation, the first segment 311 and the third segment 313 are arranged in parallel, with equal lengths. The rotation axes of the first connecting end and the second connecting end are collinear to ensure smooth rotation of both ends. When rotating the locking handle 3, the second segment 312 can be held, simultaneously rotating the first segment 311 and the third segment 313 to ensure balanced force on the locking handle 3 and prevent tilting or instability under load. Optionally, the first segment 311, the second segment 312, and the third segment 313 are integrally formed. The first and second connecting ends can be rotatably connected to the first connecting seat 1 via shaft holes or hinges.

[0057] In an embodiment of this utility model, the snap-fit ​​gear 32 includes two gears, which are respectively arranged around the rotation axis of the first connecting end and the rotation axis of the second connecting end.

[0058] In this embodiment, the central axes of the two locking gears 32 are respectively set to correspond to the rotation axes of the first connecting end and the second connecting end. Correspondingly, the two sides of the second connecting seat 2 are also provided with first slots 25 to engage with the first teeth 321 on the two locking gears 32. When the locking handle 3 locks the relative position of the first connecting seat 1 and the second connecting seat 2, the first teeth 321 on the two locking gears 32 are respectively engaged in the first slots 25 on both sides of the second connecting seat 2 to ensure the uniformity of the force on the first connecting seat 1 and the second connecting seat 2, and to effectively improve the stability of the locking handle 3 when locked.

[0059] In actual implementation, the rotation axis of the first connecting end and the rotation axis of the second connecting end are set collinearly to ensure the synchronization of the rotation of the two locking gears 32.

[0060] In embodiments of this utility model, such as Figures 6 to 8 As shown, the first connecting seat 1 is provided with a snap-fit ​​groove 14, and the locking handle 3 also includes a first elastic member 33 and a snap-fit ​​block 34. One end of the first elastic member 33 is connected to the grip part 31, and the other end of the first elastic member 33 is connected to the snap-fit ​​block 34. The snap-fit ​​block 34 is used to snap into the snap-fit ​​groove 14 to lock the position of the grip part 31.

[0061] In this embodiment, when the locking handle 3 is rotated to the position, locking the relative positions of the first connecting seat 1 and the second connecting seat 2, the locking block 34 on the grip 31 can be engaged with the locking groove 14 of the first connecting seat 1 to fix the position of the grip 31. This ensures that the first locking tooth 321 on the locking gear 32 continues to be tightly engaged with the first locking groove 25 of the second connecting seat 2, preventing the locking handle 3 from shaking after being locked in place, which would cause the first locking tooth 321 to come out of the first locking groove 25 and affect the locking effect on the first connecting seat 1 and the second connecting seat 2.

[0062] Specifically, the latching block 34 is connected to the gripping part 31 via the first elastic member 33, allowing the latching block 34 to move relative to the gripping part 31, making it easier to insert into or disengage from the latching slot 14. During the process of the latching block 34 being inserted into the latching slot 14, the latching block 34 is pressed against the outer periphery of the latching slot 14, causing the first elastic member 33 to elastically deform, gradually moving the latching block 34 towards the opening of the latching slot 14 until it bypasses the outer periphery and enters the latching slot 14 from the opening. The first elastic member 33 then rebounds, and the latching block 34 extends into the latching slot 14, thereby fixing the position of the locking handle 3. When unlocking the locking handle 3, the latching block 34 can be moved, causing the first elastic member 33 to deform, and then the latching block 34 can be moved out of the opening range of the latching slot 14, thus unlocking the locking handle 3. The second elastic element ensures the stability of the locking block 34 within the locking groove 14, effectively preventing the locking handle 3 from accidentally coming loose and improving the stability and reliability of the connector 100.

[0063] Optionally, the snap-fit ​​block 34 is provided with a guide slope. When the snap-fit ​​block 34 abuts against the outer periphery of the snap-fit ​​groove 14, the guide slope abuts against the outer periphery of the snap-fit ​​groove 14 to guide the snap-fit ​​block 34 to move away from the snap-fit ​​groove 14, so that the first elastic member 33 deforms and the snap-fit ​​block 34 bypasses the periphery of the snap-fit ​​groove 14. This can reduce the difficulty of the snap-fit ​​block 34 snapping into the snap-fit ​​groove 14.

[0064] In embodiments of this utility model, such as Figure 8 As shown, the gripping part 31 is provided with a first limiting groove 314, the snap-fit ​​block 34 is at least partially limited in the first limiting groove 314, the bottom of the first limiting groove 314 is provided with a limiting post 315, the snap-fit ​​block 34 is provided with a second limiting groove 3411 at one end near the limiting post 315, one end of the first elastic member 33 is sleeved on the limiting post 315, and the other end of the first elastic member 33 is limited in the second limiting groove 3411.

[0065] In this embodiment, the snap-fit ​​block 34 is movably confined within the first limiting groove 314. Thus, the first limiting groove 314 guides the snap-fit ​​block 34. When the snap-fit ​​block 34 is displaced, it also moves along the extension direction of the first limiting groove 314, preventing the snap-fit ​​block 34 from deflecting during the snap-fit ​​insertion process and thus ensuring smooth entry into the snap-fit ​​groove 14. Simultaneously, one end of the first elastic member 33 is sleeved on the limiting post 315, and the other end of the first elastic member 33 is confined within the second limiting groove 3411. The setting of the limiting post 315 and the second limiting groove 3411 restricts the deformation direction of the first elastic member 33, allowing it to deform along the moving direction of the snap-fit ​​block 34. This improves the stability of the snap-fit ​​block 34 under force and further ensures the stability of the snap-fit ​​block 34 confined within the second limiting groove 3411. Optionally, the first elastic member 33 is a helical spring.

[0066] In embodiments of this utility model, such as Figure 8 As shown, the snap-fit ​​block 34 includes a connecting part 341, a snap-fit ​​part 342, and an abutting part 343. The connecting part 341 is provided with a second limiting groove 3411. The snap-fit ​​part 342 is provided on the end side of the connecting part 341 away from the opening of the second limiting groove 3411. The snap-fit ​​part 342 is used to insert and cooperate with the second limiting groove 3411. The abutting part 343 is provided on the periphery of the connecting part 341. The abutting part 343 is used to abut against the periphery of the snap-fit ​​groove 14.

[0067] In this embodiment, the connecting portion 341 is confined within the first limiting groove 314, allowing the locking block 34 to move along the extending direction of the first limiting groove 314. The cross-sectional dimensions of the connecting portion 341 are approximately equal to those of the first limiting groove 314 to prevent the connecting portion 341 from shifting within the first limiting groove 314. One end of the connecting portion 341 is provided with the opening of the second limiting groove 3411, and the connecting portion 341 is positioned away from the opening of the second limiting groove 3411. The end of the connector 341 is provided with a locking part 342. When the locking part 342 is engaged into the locking groove 14, the abutment part 343 located on the periphery of the connecting part 341 abuts against the periphery of the locking groove 14 to limit the depth of the locking part 342 into the locking groove 14. This ensures that the first elastic member 33 does not fully rebound when the locking part 342 is engaged into the locking groove 14, applying a spring force towards the locking groove 14 to the locking block 34, preventing the locking part 342 from accidentally coming out of the locking groove 14. At the same time, the abutment part 343 can also be held by the user. When the locking handle 3 is in the unlocking position, the locking block 34 can be moved through the abutment part 343, reducing the difficulty of disengaging the locking block 34 from the locking groove 14.

[0068] Optionally, the connecting part 341, the snap-fit ​​part 342, and the abutting part 343 can be integrally formed. The abutting part 343 is located outside the first limiting groove 314 and the second limiting groove 3411 to facilitate the user's grip.

[0069] In an embodiment of this utility model, the second cooling head 23 includes a main body, a second elastic member, and a blocking member. The main body is provided with a cold flow channel and an opening communicating with the cold flow channel. One end of the second elastic member is connected to the main body, and the other end of the second elastic member is connected to the blocking member. The blocking member is disposed in the cold flow channel and is used to block the opening. When the first cooling head 13 is inserted into the second cooling head 23, at least part of the first cooling head 13 pushes the blocking member, and the second elastic member deforms to open the opening.

[0070] In this embodiment, under normal conditions, i.e., when the second cooling head 23 is not inserted into the first cooling head 13, the plugging member, under the action of the second elastic member, maintains the position of the blocked opening to seal the cold flow channel. When the first cooling head 13 is inserted into the second cooling head 23, the second cooling head 23 pushes the plugging member to move along the cold flow channel, causing the second elastic member to deform and the opening to open. The cooling medium can then flow through the opening into the first cooling head 13, i.e., the second cooling head 23 and the first cooling head 13 are connected. When the first cooling head 13 is pulled out from the second cooling head 23, the second elastic member springs back to its original position, causing the plugging member to re-seal the opening, preventing the cooling medium from flowing out of the opening. This ensures that the second cooling head 23 automatically seals when not inserted into the first cooling head 13 and automatically connects when inserted into the first cooling head 13, effectively preventing leakage between the second cooling head 23 and the first cooling head 13 during insertion and removal.

[0071] In actual implementation, the opening diameter is smaller than the inner diameter of the cold flow channel. The plug can be spherical, and its diameter is smaller than the inner diameter of the cold flow channel but larger than the opening diameter. In this way, the plug can both seal the opening and prevent blockage of the cold flow channel. The end of the cold flow channel opposite to the opening is connected to the cooling pipe 4, that is, the second cooling head 23 is only connected to the first cooling head 13 through the opening.

[0072] Optionally, the inner wall of the cold flow channel is provided with a stepped portion, one end of the second elastic element is connected to the blocking element, and the other end of the second elastic element is connected to the stepped portion. The second elastic element can be a coil spring.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
