DETAILED DESCRIPTION

[0047] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In the present application, unless specifically and expressly defined otherwise, a first feature is "on" or "under" a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0050] Signal connectors are components used to connect between electronic devices or circuits, mainly for transmitting signals or power, which provide reliable electrical connection, allowing data transmission, communication and power supply between devices. In the field of energy storage, the temperature rise requirement of the connector is getting higher and higher, and the liquid cooling technology is also gradually mature, and the ability of the connector to resist cooling liquid is also getting higher and higher, and the connector needs to be immersed in the cooling liquid for long-term use without oil leakage. However, the existing connector is difficult to achieve long-term work immersed in the cooling oil, and the oil pressure of the cooling oil is relatively large, and the traditional sealing structure is difficult to achieve good sealing.

[0051] In order to overcome the above technical problems, with reference to Figures 1-5 The connector provided by the embodiment includes a shell 01, a sealing plug 03, a contact terminal 02 and a cable. The shell 01 is provided with a terminal insertion hole 011. The sealing plug 03 is arranged in the terminal insertion hole 011, and the sealing plug 03 is provided with a threading hole 031. The contact terminal 02 is arranged in the terminal insertion hole 011 and located on the side of the head of the sealing plug 03 close to the shell 01. The cable extends from the tail of the shell 01 into the terminal insertion hole 011, passes through the threading hole 031 and is connected to the contact terminal 02, and the inner and outer wall surfaces of the sealing plug 03 are tightly attached to the cable and the shell 01 respectively.

[0052] The structure of the connector of the embodiment can be applied to a male connector or a female connector.

[0053] The contact terminal 02 is a structure for contacting each other when two connectors are connected. The cable (not shown in the figure) is a structure for connecting the contact terminal 02 and transmitting signals or currents. The cable itself has an insulating layer. When threading, the insulating layer of the cable needs to extend into the threading hole 031 and tightly contact the sealing plug 03. The conductor at the end of the cable is connected to the contact terminal 02. According to the actual application requirement, a proper number of terminal insertion holes 011 can be arranged on the shell 01. Specifically, one terminal insertion hole 011 is arranged corresponding to each contact terminal 02. One sealing plug 03 is arranged corresponding to each terminal insertion hole 011. One cable is connected corresponding to each contact terminal 02.

[0054] Based on the connector of the embodiment, the sealing plug 03 with the wire hole 031 is arranged in the terminal insertion hole 011 of the shell 01, and the cable is connected with the contact terminal 02 after passing through the sealing plug 03 during wiring. In the scheme, the sealing plug 03 is arranged in the narrow terminal insertion hole 011 to provide independent sealing protection for each contact terminal 02. The contact area of the sealing plug 03 in the terminal insertion hole 011 with the cooling oil is small, and thus the pressure borne by the sealing plug 03 is small. Therefore, the structure can provide more reliable and more compact sealing structure for each contact terminal 02, thereby improving the ability of resisting high-pressure cooling oil, providing a good sealing environment for the contact terminal 02, and ensuring the stable working of the contact terminal 02.

[0055] In an embodiment, the inner wall of the sealing plug 03 is provided with a first sealing corrugation 0321.

[0056] The first sealing corrugation 0321 can increase the contact area between the sealing plug 03 and the cable, thereby enhancing the sealing effect. This design helps to prevent cooling liquid or other corrosive substances from seeping into the connector through a small gap and causing damage. At the same time, the corrugated structure has a certain elastic deformation ability and can adapt to the slight deformation or movement of the cable to a certain extent, maintaining the continuity of the sealing.

[0057] In an embodiment, the outer wall of the sealing plug 03 is provided with a second sealing corrugation 0322.

[0058] Similarly, the second sealing corrugation 0322 can increase the contact area between the sealing plug 03 and the shell 01, thereby enhancing the sealing effect. This design helps to prevent cooling liquid or other corrosive substances from seeping into the connector through a small gap and causing damage. At the same time, the corrugated structure has a certain elastic deformation ability and can adapt to the slight deformation or movement of the cable to a certain extent, maintaining the continuity of the sealing.

[0059] In an embodiment, the contact terminal 02 is riveted and connected with the sealing plug 03 and the cable.

[0060] During assembly, the cable is first passed through the sealing plug 03, and then the contact terminal 02, the sealing plug 03, and the cable are riveted and connected, and then the contact terminal 02 and the sealing plug 03 are inserted into the terminal insertion hole 011 from the tail of the shell 01. This can greatly simplify the subsequent assembly steps, and the assembly personnel do not need to handle multiple components in a narrow space at the same time, thereby reducing the operation difficulty and assembly time.

[0061] Meanwhile, the riveting connection can ensure the precise alignment and firm connection between the contact terminal 02, the sealing plug 03 and the cable, and this pre-assembly method helps to maintain the accurate position of the assembly during the subsequent assembly process, avoiding assembly errors. Riveting connection is a mechanical connection method, which realizes fastening through metal deformation, has high connection strength and durability, and can resist the influence of external factors such as vibration and impact, ensuring the reliability of the connector in long-term use.

[0062] In addition, since the contact terminal 02, the sealing plug 03 and the cable are riveted and connected first during the assembly process, and then the whole is inserted into the terminal insertion hole 011, damage to the sealing plug 03 during the assembly process can be avoided, and this assembly method helps to maintain the integrity and sealing performance of the sealing plug 03.

[0063] In an embodiment, referring to Figure 4 , the contact terminal 02 includes a first riveting part 021, a second riveting part 022 and a contact part 023 connected in sequence, the first riveting part 021 is riveted and connected with the sealing plug 03, and the second riveting part 022 is riveted and connected with the cable.

[0064] The design of the first riveting part 021 and the second riveting part 022 makes it easier to achieve riveting connection, and these two parts usually have a large surface area and appropriate shape to provide sufficient contact area and fastening force during riveting. This design helps to ensure the firmness and durability of the riveting connection.

[0065] In an embodiment, the sealing plug 03 includes a sealing column part 032 and a connecting column part 033 connected together, the inner and outer wall surfaces of the sealing column part 032 are tightly attached to the cable and the shell 01 respectively; the connecting column part 033 is located at one end of the sealing column part 032 close to the contact terminal 02, and the first riveting part 021 is riveted and connected with the connecting column part 033.

[0066] The inner and outer wall surfaces of the sealing column part 032 are tightly attached to the cable and the shell 01 respectively, forming two tight sealing barriers, specifically, the first sealing corrugation 0321 and the second sealing corrugation 0322 are arranged in the sealing column part 032.

[0067] The design of the connecting column part 033 makes it easier for the first riveting part 021 to rivet and connect with it, and the connecting column part 033 usually has appropriate shape and size to provide sufficient contact area and fastening force during riveting. This design helps to ensure the firmness and durability of the riveting connection.

[0068] In an embodiment, referring to Figure 5The first crimping part 021 includes a connecting base sheet 0211 and two side guard sheets 0212 connected to both sides of the connecting base sheet 0211, respectively. The connecting base sheet 0211 is connected to the second crimping part 022, and the two side guard sheets 0212 embrace the connecting column part 033 from both sides, respectively.

[0069] The side guard sheets 0212 embrace the connecting column part 033 from both sides. The first crimping part 021 can firmly hold the sealing plug 03 through the embracing structure, thereby ensuring the reliability of the connection between the contact terminal 02 and the sealing plug 03.

[0070] In an embodiment, the connecting column part 033 is provided with an anti-disengagement flange 0331 at an end away from the sealing column part 032. The anti-disengagement flange 0331 limits the side guard sheets 0212 from disengaging from the connecting column part 033.

[0071] The presence of the anti-disengagement flange 0331 provides a physical barrier for the side guard sheets 0212, preventing them from disengaging from the connecting column part 033 when subjected to external forces. This ensures that the connection between the connecting terminal and the sealing plug 03 is more stable, thereby improving the overall reliability of the connector.

[0072] In an embodiment, the housing 01 is provided with a plurality of terminal insertion holes 011. Each terminal insertion hole 011 is provided with one sealing plug 03 and one contact terminal 02.

[0073] Providing a plurality of terminal insertion holes 011 can provide a channel for the connection of a plurality of cables and a plurality of contact terminals 02, thereby achieving the purpose of multi-channel transmission of signals and currents.

[0074] On the other hand, referring to Figures 6-17 The embodiment also provides a connector assembly, which includes a first connector 1, a second connector 2, a connecting sleeve 3, and a self-locking spring 4. The outer wall of the first connector 1 is provided with a lock groove 11. The connecting sleeve 3 is rotatably connected to the second connector 2. The inner wall of the connecting sleeve 3 is provided with a lock block 33 that cooperates with the lock groove 11. The self-locking spring 4 connects the second connector 2 and the connecting sleeve 3. The connecting sleeve 3 is driven to rotate to a position where the lock block 33 is locked with the lock groove 11 by the self-locking spring 4, so that the first connector 1 and the second connector 2 are stably connected.

[0075] The first connector 1 and the second connector 2 each include the structure of the connector described above.

[0076] Specifically, one of the first connector 1 and the second connector 2 serves as a male connector, and the other serves as a female connector.

[0077] Specifically, in combination with Figures 6-9After the first connector 1 and the second connector 2 are plugged, the first connector 1 cannot rotate relative to the second connector 2, but the first connector 1 and the second connector 2 can still be separated by relative axial movement. In order to keep the reliability of the connection between the first connector 1 and the second connector 2, the scheme is provided with a connecting sleeve 3, which is rotationally connected to the second connector 2, indicating that it can rotate relative to the second connector 2, but cannot move axially relative to the connecting sleeve 3; after plugging, the inner wall locking block 33 of the connecting sleeve 3 can be engaged with the outer wall locking groove 11 of the first connector 1, thereby limiting the relative axial movement of the connecting sleeve 3 and the first connector 1. Therefore, on the basis that the first connector 1 and the second connector 2 cannot move axially relative to the connecting sleeve 3, the freedom of relative axial movement of the first connector 1 and the second connector 2 is locked, and the first connector 1 and the second connector 2 cannot be separated.

[0078] Based on the connector assembly of the embodiment, the connecting sleeve 3 is provided, which can lock the connection between the first connector 1 and the second connector 2. In the specific structure, the connecting sleeve 3 is rotationally installed on the second connector 2, and the connecting sleeve 3 and the first connector 1 are provided with the locking block 33 and the locking groove 11 that cooperate with each other. After the first connector 1 and the second connector 2 are plugged, the connecting sleeve 3 can rotate relative to the first connector 1 and the second connector 2, so that the locking block 33 and the locking groove 11 are locked, thereby preventing the first connector 1 and the second connector 2 from being separated. Importantly, the scheme is also provided with the self-locking spring 4, which connects the second connector 2 and the locking sleeve. After plugging, the self-locking spring 4 can drive the connecting sleeve 3 to rotate to the position where the locking block 33 and the locking groove 11 are locked by using the elastic force of the self-locking spring 4, thereby avoiding the problem of free rotation of the connecting sleeve 3 that causes connection loosening and failure.

[0079] In summary, in the scheme, the elastic force of the self-locking spring 4 is used to keep the connection between the connecting sleeve 3 and the first connector 1 locked, which can avoid the problem of free rotation of the connecting sleeve 3 that causes connection loosening and failure during use. In addition, the self-locking spring 4 can compensate for the wear caused by repeated disassembly and installation through its elastic deformation allowance, thereby ensuring that the connection remains firm after long-term repeated use and increasing the service life of the connector.

[0080] In an embodiment, in combination with Figure 13 and Figure 14 , the outer wall of the second connector 2 and / or the inner wall of the connecting sleeve 3 is provided with a receiving groove 21, and the self-locking spring 4 is arranged in the receiving groove 21, one end of the self-locking spring 4 abuts against the second connector 2, and the other end abuts against the connecting sleeve 3, thereby driving the connecting sleeve 3 to rotate.

[0081] The accommodation groove 21 can be arranged on the outer wall of the second connector 2, or on the inner wall of the connecting sleeve 3, or both, to provide more stable support and more uniform spring pressure distribution. The shape and size of the accommodation groove 21 should be customized according to the shape and size of the self-locking spring 4 to ensure that the spring can be firmly installed in the groove while allowing it to freely stretch and rotate. One end of the self-locking spring 4 abuts against the second connector 2, and the other end abuts against the connecting sleeve 3. When the first connector 1 and the second connector 2 are plugged in, the spring force will push the connecting sleeve 3 to rotate relative to the second connector 2 until the locking block 33 inside the connecting sleeve 3 is fully locked with the locking groove 11 on the first connector 1; the self-locking spring 4 not only drives the rotation of the connecting sleeve 3, but also maintains the tight locking state between the locking block 33 and the locking groove 11 through its continuous spring force, effectively preventing the loosening of the connector.

[0082] The design of the accommodation groove 21 allows the self-locking spring 4 to be compactly installed inside the connector, reducing the overall size of the connector and improving space utilization; the concealed installation and stable support of the self-locking spring 4 enhance the overall structural stability of the connector, making it better able to withstand vibration and impact loads; in addition, since the self-locking spring 4 is protected by the accommodation groove 21, damage to the spring caused by external environmental factors (such as dust, moisture, etc.) is reduced, thereby extending the service life of the connector and simplifying maintenance work.

[0083] In one embodiment, the accommodation groove 21 is arranged on the outer wall of the second connector 2, and the self-locking spring 4 is completely embedded in the accommodation groove 21 with one end abutting against the second connector 2; the inner wall of the connecting sleeve 3 is provided with a matching push block 31, which is embedded in the accommodation groove 21, and the other end of the self-locking spring 4 abuts against the matching push block 31.

[0084] When the first connector 1 and the second connector 2 are plugged in, the spring force of the self-locking spring 4 is transmitted to the connecting sleeve 3 through the matching push block 31, pushing the connecting sleeve 3 to rotate relative to the second connector 2, and as the connecting sleeve 3 rotates, the locking block 33 on its inner wall gradually aligns with and locks with the locking groove 11 on the first connector 1; during this process, the spring force of the self-locking spring 4 always maintains the tight contact between the locking block 33 and the locking groove 11, effectively preventing the loosening of the connector.

[0085] The inner wall of the connecting sleeve 3 is provided with a matching push block 31, and the main purpose of this design is to achieve precise matching with the other end of the self-locking spring 4. The matching push block 31 provides another support point for the spring, ensuring that the spring can generate sufficient driving force when pushing the connecting sleeve 3 to rotate.

[0086] In an embodiment, the second connector 2 is provided with a first insertion slot 22 communicating with one side of the accommodation slot 21, the first insertion slot 22 is correspondingly arranged with the matching push block 31, and the first insertion slot 22 allows the matching push block 31 to slide into the accommodation slot 21.

[0087] The first insertion slot 22 is arranged on the second connector 2, communicates with the accommodation slot 21, and is correspondingly arranged with the matching push block 31. The main function of this design is to allow the matching push block 31 to smoothly slide into the accommodation slot 21 during the assembly of the connector, and to realize precise matching with the self-locking spring 4. The size and shape of the first insertion slot 22 should be customized according to the size and shape of the matching push block 31, so as to ensure that the push block can smoothly slide into and stably stay in the accommodation slot 21.

[0088] When the connecting sleeve 3 is assembled on the second connector 2, first align the matching push block 31 with the first insertion slot 22, and axially move the connecting sleeve 3 to be sleeved on the second connector 2. After the matching push block 31 moves to the accommodation slot 21, rotate the connecting sleeve 3, so that the matching push block 31 is limited to the accommodation slot 21 and cooperates with the self-locking spring 4.

[0089] In an embodiment, in combination with Figure 13 , the outer wall of the second connector 2 is provided with a rotating connection slot 23, and the inner wall of the connecting sleeve 3 is provided with a rotating connection protrusion 32 corresponding to the rotating connection slot 23. The rotating connection protrusion 32 is embedded in the rotating connection slot 23, and the rotating connection slot 23 guides the rotation of the connecting sleeve 3 relative to the second connector 2, while limiting the axial movement of the connecting sleeve 3 away from the second connector 2.

[0090] The design of the rotating connection slot 23 on the outer wall of the second connector 2 and the rotating connection protrusion 32 on the inner wall of the connecting sleeve 3 is a key innovation point, which ensures the stability and reliability of the connector during the rotation locking process, and prevents the connecting sleeve 3 from being axially separated from the second connector 2.

[0091] In an embodiment, in combination with Figure 14 , the second connector 2 is provided with a second insertion slot 24 communicating with one side of the rotating connection slot 23, the second insertion slot 24 is correspondingly arranged with the rotating connection protrusion 32, and the second insertion slot 24 allows the rotating connection protrusion 32 to slide into the rotating connection slot 23.

[0092] The second insertion slot 24 is ingeniously arranged on the second connector 2, communicates with the rotating connection slot 23, and is correspondingly arranged with the rotating connection protrusion 32. The main function of this design is to allow the rotating connection protrusion 32 to smoothly slide into the rotating connection slot 23 during the assembly of the connector, so as to ensure that the connecting sleeve 3 can stably rotate and lock on the second connector 2.

[0093] In the process of assembling the connecting sleeve 3 to the second connector 2, the rotating connecting protrusion 32 is aligned with the second insertion slot 24, and the connecting sleeve 3 is axially moved to be sleeved on the second connector 2, the rotating connecting protrusion 32 is moved to the rotating connecting slot 23, and then the connecting sleeve 3 is rotated, so that the rotating connecting protrusion 32 is limited in the rotating connecting slot 23.

[0094] In an embodiment, in combination Figure 16 , the outer wall of the first connector 1 is provided with a third insertion slot 12, and the third insertion slot 12 allows the lock block 33 to slide into the bottom of the lock slot 11.

[0095] The third insertion slot 12 is arranged on the outer wall of the first connector 1, corresponding to the lock block 33 and the lock slot 11, and the main function of this design is to allow the lock block 33 to smoothly slide into the bottom of the lock slot 11 during the connector plugging process, thereby realizing the quick locking of the connector.

[0096] During the connector assembly or plugging process, the lock block 33 first slides into the bottom of the lock slot 11 through the third insertion slot 12, which simplifies the assembly process, reduces the assembly time and cost, and improves the assembly accuracy. With the plugging of the first connector 1 and the second connector 2, the connecting sleeve 3 rotates under the elastic force of the self-locking spring 4, pushes the lock block 33 to move along the track of the lock slot 11, until the lock block 33 is completely locked in the lock slot 11, and the design of the third insertion slot 12 makes the lock block 33 more easily enter the bottom of the lock slot 11, thereby speeding up the locking process.

[0097] In an embodiment, the third insertion slot 12 is trumpet-shaped towards the insertion direction of the lock block 33.

[0098] The opening part of the third insertion slot 12 is designed to be trumpet-shaped, that is, the opening gradually expands towards the insertion direction of the lock block 33, and the main function of this design is to guide the lock block 33 to more easily enter the lock slot 11 and gradually align with the lock slot 11 during the insertion process, thereby simplifying the alignment and locking process.

[0099] Importantly, the trumpet-shaped third insertion slot 12 can greatly facilitate the user's plugging operation. Referring to Figure 4In particular, during the plugging process, the user aligns the first connector 1 with the second connector 2, the lock block 33 first rotates along the third insertion slot 12 in the direction of avoiding unlocking, and the self-locking spring 4 is further compressed during the process; when sliding to the bottom of the third insertion slot 12 (i.e. the position of aligning the lock slot 11), the connecting sleeve 3 is pushed to rotate in the locking direction under the elastic force of the self-locking spring 4, driving the lock block 33 to slide into the lock slot 11 to achieve locking. That is, during the entire assembly process, the user does not need to manually twist the connecting sleeve 3, but only needs to axially align the second connector 2 for insertion, and the plugging process is extremely simple and convenient. Conversely, when unlocking, the user needs to twist the connecting sleeve 3 in the direction of unlocking, and the lock block 33 will slide out along the third insertion slot 12 during the twisting process, and the second connector 2 is pushed out synchronously during the sliding process, that is, the operation of quick pulling out is achieved.

[0100] In an embodiment, in combination with Figure 15 One side of the lock block 33 is provided with a guide inclined surface 331, which can guide the lock block 33 to slide into the third insertion slot 12.

[0101] During the assembly or plugging process of the connector, the lock block 33 gradually slides into the third insertion slot 12 along the guide inclined surface 331, which makes the lock block 33 more easily find the entrance of the third insertion slot 12 and smoothly enter the bottom of the lock slot 11, thereby further simplifying the assembly process.

[0102] In an embodiment, referring to Figure 9 The inner wall of the first housing of the first connector 1 is provided with a sealing ring 5, and after the first connector 1 is plugged with the second connector 2, the sealing ring 5 abuts against the second connector 2, thereby achieving sealing and waterproofing after the butt joint.

[0103] In an embodiment, referring to Figures 16-17 Further comprising a mounting plate 6 for supporting the first connector 1, the mounting plate 6 is provided with a hole position, the first connector 1 is provided with a threaded portion and a shoulder, the first connector 1 abuts against the mounting plate 6 after passing through the hole position, and a mounting nut 61 is installed on the threaded portion, thereby fixing the first connector 1 to the mounting plate 6.

[0104] Preferably, a buffer pad 62 is arranged between the mounting plate 6 and the shoulder.
