Description

Technical Field

[0002] In the field of new energy battery technology, battery pack connectors are key components for connecting battery packs to external systems, and their performance directly affects the safety and reliability of the entire system.

[0003] Currently, the sealing ring design of existing connectors has significant technical shortcomings, making it difficult to adapt to the unavoidable dimensional differences during component manufacturing. This design flaw easily leads to two types of problems: first, excessive clearance between the sealing ring and the component causes waterproofing failure; second, insufficient clearance accelerates the aging and wear of the sealing ring. Furthermore, due to the combined effects of manufacturing tolerances and assembly errors, even connectors from the same batch cannot guarantee that all products achieve ideal sealing performance, posing safety hazards. More importantly, the sealing ring will age or deform due to environmental factors during long-term use, and traditional connector structures cannot adjust the sealing condition, requiring the replacement of the entire connector to solve the problem, significantly increasing subsequent maintenance costs.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-6 An electrical connector 100 according to a first aspect embodiment of the present invention is described.

[0029] like Figures 1-4 As shown, the electrical connector 100 according to the first aspect of the present invention includes: a first insertion assembly 10, a second insertion assembly 20, a sealing member 30, and an adjustment mechanism 40.

[0030] Specifically, the first plug-in assembly 10 includes a socket 11 and a first conductive element 12 disposed on the socket 11; the second plug-in assembly 20 includes a plug 21 and a second conductive element 22 disposed on the plug 21, the plug 21 and the socket 11 being connected in a first direction (e.g., Figure 4 The first conductive element 12 is connected to the second conductive element 22 in the left-right direction shown in the figure, so that the first conductive element 12 is electrically connected to the second conductive element 22. The first direction is the length direction of the first plug assembly 10. The sealing element 30 extends in an annular shape around the first direction. In the radial direction of the sealing element 30, the sealing element 30 seals against the plug 21 and the socket 11. The adjusting mechanism 40 is provided on the socket 11 or the plug 21. The adjusting mechanism 40 is configured to adjust the amount of compression of the sealing element 30 along the first direction.

[0031] like Figures 1-4 As shown, the sealing element 30 is a sealing ring, which is annular and sleeved on the outside of the plug 21. When the first plug assembly 10 and the second plug assembly 20 need to be plugged in, one end of the plug 21 is inserted into the socket 11. At this time, the sealing element 30 abuts against the inner wall of the socket and the outer peripheral surface of the plug 21 to achieve a seal. This allows the first conductive element 12 and the second conductive element 22 to be electrically connected while being isolated from the external environment. This ensures that the first conductive element 12 and the second conductive element 22 are not affected by the external environment, ensuring the stability and reliability of the electrical connection between the first conductive element 12 and the second conductive element 22, and ensuring the sealing performance of the plugging connection between the first plug assembly 10 and the second plug assembly 20.

[0032] Furthermore, the electrical connector 100 of this embodiment also includes an adjustment mechanism 40. The adjustment mechanism 40 can be disposed on the socket 11 or on the plug 21. The adjustment mechanism 40 is used to adjust the compression amount of the seal 30 in the first direction. For example, the adjustment mechanism 40 can be configured to push the seal 30 in the first direction. By further pressing or releasing the seal 30, the compression amount of the seal 30 can be adjusted. Alternatively, the adjustment mechanism 40 can also be provided with an elastic abutment member. The elastic abutment member abuts against the seal 30. The elastic abutment member can be pre-compressed. When the compression amount of the seal 30 decreases, the elastic abutment member can automatically compensate for the compression amount of the seal 30.

[0033] In this embodiment, by setting an adjustment mechanism 40 to adjust the compression amount of the sealing element 30, the sealing element 30 can be precisely matched to the sealing requirements, avoiding sealing failure. For example, the compression amount can be increased to enhance the sealing surface fit and reduce the risk of sealing failure. Alternatively, the compression amount can be reduced to prevent contact damage caused by excessive deformation of the sealing element 30.

[0034] Meanwhile, the sealing gap of the first plug-in component 10 and the second plug-in component 20 of the electrical connector 100 may change due to processing errors or environmental changes. By adjusting the compression of the sealing element 30 by the adjustment mechanism 40, these deviations can be flexibly compensated, and sealing failure caused by the inability to adapt to a fixed compression amount can be avoided.

[0035] Furthermore, after prolonged use, the seal 30 may experience aging, permanent deformation, or seal failure due to undervoltage. In such cases, adjusting the compression of the seal 30 via the adjusting mechanism 40 can control the compression of the seal 30 within the optimal range, thereby reducing material consumption, lowering frictional resistance during insertion and removal, reducing wear on the seal 30, improving the durability of the electrical connector 100, and extending the service life of the seal 30.

[0036] According to the embodiment of the present invention, the electrical connector 100 is provided with an adjustment mechanism 40 for adjusting the compression amount of the seal 30 along the first direction. By changing the compression amount of the seal 30, the seal 30 can be adapted to different dimensional tolerances and processing errors. Furthermore, the compression amount of the seal 30 can be compensated after the performance of the seal 30 deteriorates, so as to ensure the sealing performance of the seal 30 and thereby reduce the maintenance cost of the electrical connector 100.

[0037] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the socket 11 defines a sealing cavity 112, which faces the plug 21 in a first direction (e.g., Figure 4The right side of the sealing cavity shown is open. The plug 21 includes a sealing section 211, which fits into the sealing cavity 112. In the radial direction of the sealing member 30, the sealing member 30 seals against the inner circumferential surface between the sealing section 211 and the sealing cavity 112. In this embodiment, by forming a sealing cavity 112 on the socket 11, the sealing cavity 112 can provide a precise fitting space for the sealing section 211 of the plug 21 and the sealing member 30, so as to ensure that the sealing member 30 can reliably abut against the plug 21 and the socket 11, improve the blocking effect against foreign objects intruding into the socket 11, and improve the sealing performance of the connection between the plug 21 and the socket 11.

[0038] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the outer peripheral surface of the sealing section 211 is provided with a receiving groove 214 extending in an annular direction along the circumference of the sealing section 211, and the sealing element 30 is disposed within the receiving groove 214. Thus, the receiving groove 214 can position and limit the sealing element 30, preventing the sealing element 30 from shifting or falling off during the insertion of the first plug-in assembly 10 and the second plug-in assembly 20, thereby ensuring the sealing performance between the first plug-in assembly 10 and the second plug-in assembly 20. Furthermore, by providing the receiving groove 214 so that the sealing element 30 is partially accommodated within the receiving cavity, the radial gap between the sealing section 211 and the peripheral wall of the sealing cavity 112 can be reduced, thereby further improving the sealing performance between the first plug-in assembly 10 and the second plug-in assembly 20, preventing external dust and impurities from entering the plug-in cavity 111, and extending the service life of the electrical connector 100.

[0039] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the adjustment mechanism 40 is provided on the plug 21. The adjustment mechanism 40 includes a pressure ring 41, which is disposed in the receiving groove 214 and extends in a ring shape along the circumference of the receiving groove 214. The pressure ring 41 is arranged on at least one side of the seal 30 in the first direction. The position of the pressure ring 41 in the receiving groove 214 along the first direction is adjustable to adjust the compression of the seal 30.

[0040] In some examples, there may be one pressure ring 41, arranged on one side of the seal 30 in the first direction; for example, the pressure ring 41 may be arranged on the left or right side of the seal 30. The adjusting mechanism 40 pushes the seal 30 against one side wall of the receiving groove 214 via the pressure ring 41 to adjust the compression of the seal 30. In other examples, there may be two pressure rings 41, arranged on opposite sides of the seal 30 in the first direction. The adjusting mechanism 40 can clamp the seal 30 along the first direction using the two pressure rings 41 to adjust the compression of the seal 30 in the first direction.

[0041] In this embodiment, an annular pressure ring 41 is provided in the receiving groove 214 of the plug 21, and the position of the pressure ring 41 along the first direction is adjustable. By adjusting the position of the pressure ring 41 in the first direction, the compressive force on the seal 30 can be flexibly increased or decreased, so that the compression amount of the seal 30 is adapted to the optimal range required by different working conditions. This achieves precise control of the compression amount of the seal 30, avoiding overpressure leading to aging and deformation of the seal 30 or underpressure leading to sealing failure.

[0042] Meanwhile, the annular pressure ring 41 can apply force evenly to the seal 30 around the circumference of the receiving groove 214, preventing the seal 30 from shifting due to uneven local force, and ensuring a tight fit with the inner wall of the sealing cavity 112; and the pressure ring 41 can limit the seal 30, and when insertion or removal is required, the position of the pressure ring 41 can be adjusted to reduce the squeezing force of the pressure ring 41 on the seal 30, thereby reducing the wear of the seal 30 during insertion and removal, and further improving the sealing reliability and service life of the electrical connector 100.

[0043] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the adjusting mechanism 40 includes an adjusting member 42, which is connected to the pressure ring 41 and is used to drive the pressure ring 41 to move along a first direction. Therefore, the position of the pressure ring 41 can be controlled by the adjusting member 42, making it easy and convenient to control the pressure on the sealing element 30, and simplifying operation. The adjusting member 42 can be manually or automatically adjusted. When the adjusting member 42 is manually adjusted, it can be an adjusting screw, adjusting nut, paddle, or adjusting knob, etc.

[0044] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the plug 21 may also include a main body section 212, which is connected to the sealing section 211 on the side away from the socket 11 along the first direction. The adjusting member 42 is disposed on the main body section 212. The adjusting mechanism 40 also includes a transmission assembly 43, which is connected between the adjusting member 42 and the pressure ring 41.

[0045] like Figure 3 and Figure 4As shown, the plug 21 extends in a cylindrical shape along a first direction. The plug 21 includes a sealing section 211, a main body section 212, and a connecting section 213. The sealing section 211, connecting section 213, and main body section 212 are all cylindrical and sequentially connected along the first direction. For example, the sealing section 211, connecting section 213, and main body section 212 can all extend in a cylindrical shape along the first direction and be sequentially connected and coaxially arranged. The cross-sectional area of ​​the sealing section 211 is smaller than that of the connecting section 213, and the cross-sectional area of ​​the connecting section 213 is smaller than that of the main body section 212. A receiving groove 214 is provided on the outer peripheral surface of the sealing section 211, and an adjusting member 42 is provided on the main body section 212.

[0046] In this embodiment, a transmission assembly 43 is connected between the adjusting member 42 and the pressure ring 41. When the adjusting member 42 is operated, it drives the pressure ring 41 to move along a first direction via the transmission assembly 43, thereby adjusting the compression force on the sealing member 30 and adjusting the compression amount of the sealing member 30. Thus, the transmission assembly 43 can easily convert and transmit the movement of the adjusting member 42 to the pressure ring 41, ensuring smooth execution of the adjustment operation. Furthermore, the adjusting member 42 can be operated externally to the electrical connector 100 to adjust the compression amount of the sealing member 30 located in the sealing cavity 112, making operation convenient. The transmission assembly 43 can be a worm gear mechanism, a lead screw mechanism, a connecting rod mechanism, etc.

[0047] In some embodiments of this utility model, such as Figures 3-5 As shown, the transmission assembly 43 may include: a lead screw 431 and a threaded sleeve 432, the lead screw 431 extending along a first direction, one end of the lead screw 431 (e.g. Figure 4 The left end of the lead screw 431 shown is fixedly connected to the pressure ring 41; the threaded sleeve 432 is threadedly fitted onto the lead screw 431, and the adjusting member 42 is connected to the threaded sleeve 432 to drive the threaded sleeve 432 to rotate. (See reference...) Figure 3 The adjusting member 42 can be set as an annular shape along the circumference of the plug 21. In this case, the central axis of the annular adjusting member 42 is set parallel to the central axis of the threaded sleeve 432.

[0048] In this embodiment, the specific structure of the adjusting member 42 is not limited, as long as the adjusting member 42 can drive the threaded sleeve 432 to rotate. For example, the adjusting member 42 can be a drive knob fixed coaxially with the threaded sleeve 432. By turning the drive knob, the drive knob can drive the threaded sleeve 432 to rotate synchronously around its central axis. As another example, the adjusting member can be a drive handle fixed to the threaded sleeve 432 and eccentrically positioned on the central axis of the threaded sleeve 432. By pushing the drive handle along the circumference of the threaded sleeve, the drive handle can drive the threaded sleeve 432 to rotate around its central axis. Here, the rotation center axis of the adjusting member (drive handle) is coaxial with the rotation center axis of the threaded sleeve 432.

[0049] When the adjusting element 42 directly or indirectly drives the threaded sleeve 432 to rotate, since the threaded sleeve 432 is threadedly engaged with the lead screw 431, and the lead screw 431 extends along the first direction and is fixed to the pressure ring 41, the rotational motion of the threaded sleeve 432 can be converted into the axial movement of the lead screw 431, which in turn drives the pressure ring 41 to move along the first direction, thereby changing the squeezing force of the pressure ring 41 on the seal 30 and adjusting the compression amount of the seal 30.

[0050] This embodiment improves transmission accuracy by including a lead screw 431 and a threaded sleeve 432 in the transmission assembly 43, precisely controlling the displacement of the pressure ring 41 along the first direction, ensuring that the compression of the seal 30 is stable within the optimal range. At the same time, the threaded transmission has self-locking properties, which can effectively prevent the pressure ring 41 from shifting, further improving the sealing reliability.

[0051] In some embodiments of this utility model, such as Figures 4-6 As shown, there are multiple transmission components 43, which are arranged at intervals along the circumference of the pressure ring 41. For example, the number of transmission components 43 can be two, three, four, five, six, eight, or ten, etc., and the multiple transmission components 43 can be evenly spaced along the circumference of the pressure ring 41.

[0052] In this embodiment, multiple transmission components 43 are arranged at intervals along the circumference of the pressure ring 41. The multiple transmission components 43 can apply force synchronously from different circumferential positions of the pressure ring 41, driving the pressure ring 41 to move smoothly along the first direction. This can prevent the pressure ring 41 from tilting or shifting due to uneven force, ensure that the compression of the seal 30 is uniform in the circumference, and avoid the occurrence of local underpressure leakage or overpressure damage.

[0053] In some embodiments of this utility model, such as Figures 4-6As shown, the transmission assembly 43 may further include: a first gear 433, which is sleeved on the outside of the threaded sleeve 432 and fixed to the threaded sleeve 432; an adjusting member 42 is connected to the first gear 433 and is used to drive the first gear 433 to rotate. Specifically, when the adjusting member 42 drives the first gear 433 to rotate, since the first gear 433 is fixed to the threaded sleeve 432, it drives the threaded sleeve 432 to rotate synchronously; the threaded sleeve 432 is threadedly engaged with the lead screw 431, converting the rotation of the threaded sleeve 432 into the movement of the lead screw 431 along the first direction, thereby driving the pressure ring 41 to move and adjusting the compression of the sealing member 30.

[0054] In the above embodiments, the adjusting member 42 can be a gear or worm gear meshing with the first gear 433. When the gear or worm gear of the adjusting member 42 rotates, it can drive the first gear 433 to rotate through meshing. The first gear 433 then drives the coaxial threaded sleeve 432 to rotate. At this time, the central axis of the adjusting member (gear or worm gear) is parallel to and spaced apart from the central axis of the first gear. The adjusting member 42 can also be connected to the first gear 433 through a gear or worm gear, that is, the adjusting member 42 drives the first gear 433 to rotate through the gear or worm gear, thereby driving the coaxially fixed threaded sleeve 432 to rotate.

[0055] In some embodiments of this utility model, such as Figures 4-6 As shown, the adjusting mechanism 40 may further include: a gear ring 44, which extends in a ring shape along the circumference of the main body section 212; a first gear 433 is arranged on the inner side of the gear ring 44 and meshes with the gear ring 44; an adjusting member 42 extends in a ring shape along the circumference of the main body section 212 and is rotatably sleeved on the outer side of the main body section 212; and the gear ring 44 and the adjusting member 42 are fixed.

[0056] When it is necessary to adjust the compression of the seal 30, the annular adjusting member 42 sleeved on the outside of the plug 21 can be manually rotated. At this time, the annular gear ring 44 fixedly connected to the adjusting member 42 will rotate synchronously. Since multiple first gears 433 are arranged circumferentially along the inner side of the gear ring 44 and mesh with the gear ring 44, the rotation of the gear ring 44 will simultaneously drive all the first gears 433 to rotate in the same direction and at the same speed. Since each first gear 433 is fixed to the corresponding threaded sleeve 432, the first gear 433 can drive the corresponding threaded sleeve 432 to rotate synchronously. The threaded sleeve 432 is threadedly engaged with the lead screw 431 extending along the first direction. The rotational motion of the threaded sleeve 432 is converted into the axial movement of the lead screw 431, which ultimately pushes the pressure ring 41 fixed to the lead screw 431 to move smoothly along the first direction, thereby achieving precise adjustment of the compression of the seal 30.

[0057] In this embodiment, by setting a gear ring 44, which meshes with multiple first gears 433, multiple transmission components 43 can operate synchronously, making the circumferential force on the pressure ring 41 more uniform and avoiding insufficient or excessive local compression of the seal 30 due to the tilting of the pressure ring 41. At the same time, by setting the adjusting member 42 as a ring, the adjusting member 42 can be rotated around the plug 21 with one hand, making the operation of the adjusting member 42 more convenient and without the need for tools.

[0058] In some embodiments of this utility model, such as Figures 4-6 As shown, a recessed first receiving groove 215 is provided on the outer peripheral surface of the main body section 212. The first receiving groove 215 extends in a ring shape along the circumference of the main body section 212. A second receiving groove 216 is provided on the bottom wall of the first receiving groove 215, which is recessed radially inward. The gear ring 44 is located in the first receiving groove 215, and the first gear 433 is located in the second receiving groove 216. The receiving groove 214 is formed by the radial inward recess of the outer peripheral surface of the sealing section 211. A connecting hole 217 extending in the first direction is formed on the plug 21. The second receiving groove 216 and the receiving groove 214 are connected through the connecting hole 217. The lead screw 431 passes through the connecting hole 217.

[0059] In some examples, there are multiple second receiving slots 216, each corresponding to a multiple first gears 433. In a projection plane perpendicular to the first direction, the inner wall of the second receiving slot 216 is arc-shaped; further, the projection of the inner wall of the second receiving slot 216 is a large arc. There are also multiple connecting holes 217, each corresponding to a multiple lead screw 431.

[0060] In this embodiment, by setting a recessed first receiving groove 215 and a second receiving groove 216 on the main body section 212, on the one hand, the transmission component 43 and the gear ring 44 can avoid occupying the space on the radially outer side of the socket 11, resulting in a compact structure. On the other hand, by arranging the gear ring 44 and the first gear 433 in the first receiving groove 215 and the second receiving groove 216 respectively, the mutual interference between the gear ring 44 and the first gear 433 can be reduced, and the shaking of the gear ring 44 and the first gear 433 during the transmission process can be reduced, thereby improving the adjustment accuracy.

[0061] In this embodiment, by providing a connecting hole 217, the lead screw 431 is inserted into the connecting hole 217. The connecting hole 217 not only provides space for the lead screw 431 to be arranged, but also provides guidance for the movement of the lead screw 431 along the first direction, so as to avoid the lead screw 431 from deviating or tilting, and to ensure the accuracy and reliability of the sealing adjustment.

[0062] In some embodiments of this utility model, such as Figures 1-4As shown, the socket 11 defines a plug cavity 111, which is connected to the sealing cavity 112 in a first direction. The plug cavity 111 is arranged on the side of the sealing cavity 112 away from the plug 21 in the first direction. The first conductive member 12 has a first plug portion 121 disposed in the plug cavity 111. The second conductive member 22 has a second plug portion 221 disposed in the plug cavity 111 and plugged into the first plug portion 121.

[0063] In this embodiment, by connecting the insertion cavity 111 and the sealing cavity 112 in a first direction, and with the insertion cavity 111 located on the side of the sealing cavity 112 away from the plug 21, the insertion cavity 111 provides a precise docking space for the first insertion part 121 and the second insertion part 221, ensuring the accuracy and stability of the insertion connection between the first insertion part 121 and the second insertion part 221, and ensuring smooth conductive path of the first conductive element 12 and the second conductive element 22. Simultaneously, by arranging the sealing cavity 112 on the side of the insertion cavity 111 facing the plug 21, the sealing cavity 112 and the sealing element 30 can provide front-end protection for the first insertion part 121 and the second insertion part 221 located within the insertion cavity 111, effectively preventing dust, moisture, and other foreign objects from entering the conductive parts within the insertion cavity 111, significantly improving the safety and reliability of the connection between the socket 11 and the plug 21.

[0064] like Figures 1-4 As shown, the socket 11 extends in a columnar shape along a first direction, which is the left-right direction. The socket 11 defines a plug-in cavity 111 and a sealing cavity 112. The plug-in cavity 111 and the sealing cavity 112 are arranged and connected along the left-right direction. The plug-in cavity 111 and the sealing cavity 112 are coaxially arranged. The plug-in cavity 111 is located on the side of the sealing cavity 112 opposite to the plug 21, and the cross-sectional area of ​​the plug-in cavity 111 is smaller than the cross-sectional area of ​​the sealing cavity 112. The socket 11 also has a first through hole that penetrates the bottom wall of the plug-in cavity 111 on the side opposite to the sealing cavity 112 along the left-right direction. The first conductive element 12 includes a first plug-in portion 121 and a first conductor. The first plug-in portion 121 is arranged inside the plug-in cavity 111. One end of the first conductor is connected to the first plug-in portion 121, and the other end extends through the first through hole to the side of the socket 11 opposite to the plug 21. The first plug-in portion 121 may be provided with a plug hole 1211 or a plug pin 2211 for plugging and connecting with the second conductive member 22. Further, a first positioning groove is formed on the bottom wall of the plug cavity 111 on the side opposite to the sealing cavity 112. The end of the first plug-in portion 121 connected to the first conductor fits into the first positioning groove, and the end of the first through hole penetrates the bottom wall of the first positioning groove.

[0065] like Figure 4As shown, the plug 21 extends in a cylindrical shape along a first direction. A second through hole is formed on the plug 21, extending through the plug 21 along the first direction. The second conductive element 22 includes a second plug portion 221 and a second conductor. The second plug portion 221 is arranged on the side of the plug 21 facing the socket 11. One end of the second conductor is connected to the second plug portion 221, and the other end extends through the second through hole to the side of the plug 21 away from the socket 11. A second positioning groove is provided on the side of the plug 21 facing the socket 11. One end of the second through hole penetrates the bottom wall of the second positioning groove, and the end of the second plug portion 221 connected to the second conductor fits into the second positioning groove.

[0066] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the first plug-in portion 121 has multiple sockets 1211, and the second plug-in portion 221 has multiple pins 2211, each pin corresponding to a socket 1211. The number of sockets 1211 can be two, three, five, eight, ten, fifteen, twenty, or more. This embodiment, by having multiple pins 2211 corresponding to multiple sockets 1211, can precisely achieve the alignment and connection of the first plug-in portion 121 and the second plug-in portion 221, ensuring the stability of current or signal transmission. It also increases the contact area between the first plug-in portion 121 and the second plug-in portion 221, reducing contact resistance, minimizing heat loss, and reducing the risk of loosening due to vibration.

[0067] In some embodiments of this utility model, such as Figures 3-4 As shown, the second plug-in assembly 20 may further include: a protective sleeve 23, which extends along the first direction and is sleeved on the outside of the second plug-in portion 221, with one end of the protective sleeve 23 (e.g. Figure 4 The right end of the protective sleeve 23 shown is fixed to the plug 21, and the other end of the protective sleeve 23 (e.g., Figure 4 The left end of the protective sleeve 23 shown extends beyond the end of the pin 2211 away from the sealing section 211 (e.g., the end facing away from the sealing section 211). Figure 4 The left end edge of the pin 2211 shown.

[0068] When the first insertion assembly 10 and the second insertion assembly 20 are inserted and connected, the protective cylinder 23 can extend through the sealing cavity 112 into the insertion cavity 111. This serves to guide and position the second insertion assembly 20, improving insertion efficiency. Simultaneously, the protective cylinder 23 can cover multiple pins 2211, thereby reducing the risk of collision between the pins 2211 and the inner walls of the sealing cavity 112 and the insertion cavity 111, preventing the pins 2211 from being bent or damaged, and extending their service life. Furthermore, the protective cylinder 23 can reduce the risk of operators accidentally touching the pins 2211 during the insertion process, improving safety.

[0069] In some embodiments of this utility model, such as Figures 2-4 As shown, a guide protrusion 113 is formed on one of the outer peripheral surface of the protective cylinder 23 and the inner wall surface of the insertion cavity 111, and a guide groove 231 is formed on the other. The guide protrusion 113 is slidably fitted into the guide groove 231 along the first direction. For example, when the guide protrusion 113 is provided on the outer peripheral surface of the protective cylinder 23, the guide groove 231 is provided on the inner wall surface of the insertion cavity 111; when the guide groove 231 is provided on the outer peripheral surface of the protective cylinder 23, the guide protrusion 113 is provided on the inner wall surface of the insertion cavity 111. Both the guide protrusion 113 and the guide groove 231 extend into an elongated shape along the first direction.

[0070] In this embodiment, during the insertion and connection of the first insertion assembly 10 and the second insertion assembly 20, the guide protrusion 113 and the guide groove 231 slide in the first direction. This provides precise guidance for the docking process between the protective cylinder 23 and the insertion cavity 111, and for the insertion process between the first insertion part 121 and the second insertion part 221. This prevents misalignment and ensures that the pin 2211 is aligned with the socket 1211, thereby improving insertion efficiency. Simultaneously, the guide protrusion 113, fitted within the guide groove 231, also restricts the circumferential rotation of the protective cylinder 23 relative to the socket 11, preventing the pin 2211 from twisting or shifting during insertion. This ensures stable contact between the pin 2211 and the inner wall of the socket 1211, guaranteeing the reliability and lifespan of the electrical connection between the first insertion assembly 10 and the second insertion assembly 20.

[0071] In some embodiments of this utility model, such as Figure 4 As shown, there are multiple guide protrusions 113, which are arranged at intervals along the circumference of the protective cylinder 23. There are also multiple guide grooves 231, with each guide protrusion 113 and guide groove 231 corresponding to the other. The cooperation between the multiple guide protrusions 113 and guide grooves 231 provides precise guidance for the insertion of the protective cylinder at multiple positions along the circumference of the socket 11, further improving the guiding accuracy, preventing the protective cylinder 23 from shifting or twisting during docking, ensuring the positional accuracy of the insertion, further improving the insertion efficiency, and further reducing the probability of the protective cylinder 23 shaking, thereby improving the reliability and durability of the electrical connection between the first plug-in assembly 10 and the second plug-in assembly 20.

[0072] In some embodiments of this utility model, such as Figures 1-4As shown, the first plug-in assembly 10 further includes a connecting sleeve 13, which extends along a first direction. Both ends of the connecting sleeve 13 are respectively fitted onto the outside of the socket 11 and the plug 21, and are threadedly connected to the socket 11 and the plug 21, respectively. For example, the connecting sleeve 13 can be fitted onto the outside of the socket 11 and threadedly connected to it. After the first plug-in assembly 10 and the second plug-in assembly 20 are plugged in, the connecting sleeve 13 can be screwed on to thread it onto the plug 21. This further improves the connection strength and reliability between the first plug-in assembly 10 and the second plug-in assembly 20. Furthermore, the connecting sleeve 13 can also enclose the connection position (seam) between the plug 21 and the socket 11, thereby further improving the sealing performance between the first plug-in assembly 10 and the second plug-in assembly 20. In addition, the threaded connection improves the assembly and disassembly efficiency of the electrical connector 100.

[0073] The battery device according to a second aspect of the present invention includes an electrical connector 100 according to the first aspect of the present invention described above.

[0074] According to the battery device of the present invention, by providing the electrical connector 100 of the first aspect embodiment described above, the overall performance of the battery device is improved.

[0075] The following will refer to Figures 1-6 This invention describes an electrical connector 100 according to a specific embodiment of the present invention. The electrical connector 100 of this embodiment is used in a battery device, which may be a battery pack.

[0076] refer to Figure 1-6 The electrical connector 100 includes: a first plug assembly 10, a second plug assembly 20, a seal 30, and an adjustment mechanism 40. The first plug assembly 10 includes a socket 11, a first conductive element 12, and a connecting sleeve 13. The first conductive element 12 includes a connected first conductor and a first plug portion 121. The first plug portion 121 forms a plurality of plug holes 1211. The second plug assembly 20 includes a plug 21, a second conductive element 22, and a protective sleeve 23. The second conductive element 22 includes a connected second conductor and a second plug portion 221. The second plug portion 221 is provided with a plurality of pins 2211. The seal 30 is a sealing ring. The adjustment mechanism 40 includes an adjustment element 42, a gear ring 44, a pressure ring 41, and a transmission assembly 43. The transmission assembly 43 includes a lead screw 431, a threaded sleeve 432, and a first gear 433.

[0077] like Figures 2-4As shown, the socket 11 is adapted to the plug 21, the socket 1211 is adapted to the pin 2211, the right side of the socket 11 is open, and defines a coaxially arranged insertion cavity 111 and a sealing cavity 112. The sealing cavity 112 is arranged and connected to the right side of the insertion cavity 111. The cross-sectional diameter of the insertion cavity 111 is smaller than the cross-sectional diameter of the sealing cavity 112. The first insertion part 121 of the first conductive member 12 is provided in the insertion cavity 111 of the socket 11, and the left end of the first conductor of the first conductive member 12 extends to the left side of the socket 11. The inner peripheral wall of the insertion cavity 111 is provided with a plurality of guide protrusions 113 arranged in a ring array. The outer surface of the socket 11 is provided with an external thread. The connecting sleeve 13 is sleeved on the outside of the socket 11 and threadedly connected to the socket 11.

[0078] The second connector 221 of the second conductive element 22 is arranged on the left side of the plug 21, and the second conductor of the second conductive element 22 extends through the plug 21 to the right side of the plug 21. A cylindrical protective tube 23 is fixedly connected to the left side of the plug 21, and the outer diameter of the protective tube 23 is adapted to the inner diameter of the plug cavity 111 of the socket 11. The pins 2211 of the second connector 221 are arranged inside the protective tube 23, and guide grooves 231 arranged in a ring array and adapted to the guide protrusions 113 are formed on the outer peripheral surface of the protective tube 23.

[0079] The plug 21 includes a sealing section 211, a connecting section 213, and a main body section 212 arranged from left to right. All three sections are cylindrical and coaxially arranged, with their cross-sectional diameters increasing sequentially. The outer diameter of the sealing section 211 matches the inner diameter of the insertion cavity 111. The outer diameter of the connecting section 213 is the same as the outer diameter of the socket 11, and the outer surface of the connecting section 213 has an external thread that matches the internal thread of the connecting sleeve 13. The outer surface of the sealing section 211 has an annular receiving groove 214, and the sealing element 30 is fitted within the receiving groove 214.

[0080] The pressure ring 41 of the adjusting mechanism 40 is located in the receiving groove 214 and is in close contact with the sealing member 30 in the left and right direction. Multiple transmission components 43 of the adjusting mechanism 40 are located in the plug 21. The multiple transmission components 43 are arranged in a ring array and are connected to the pressure ring 41 located in the receiving groove 214. The adjusting member 42 of the adjusting mechanism 40 is sleeved on the outside of the main body section 212 of the plug 21.

[0081] Multiple transmission components 43 have lead screws 431 arranged in a ring array and extending into an annular receiving groove 214. The left ends of the multiple lead screws 431 are fixedly connected to the same pressure ring 41. Multiple threaded sleeves 432 are arranged in a ring array and are respectively sleeved on the outside of the right end of the lead screws 431 and threadedly connected to the corresponding lead screws 431. Each threaded sleeve 432 has a first gear 433 fixedly connected to its outside. The adjusting member 42 is a rotating ring and is rotatably sleeved on the outside of the main body section 212 of the plug 21. The adjusting member 42 has a gear ring 44 that extends into the plug 21 and meshes with the multiple first gears 433.

[0082] When the first plug assembly 10 and the second plug assembly 20 are connected, the guide groove 231 on the outside of the protective cylinder 23 is aligned with the guide protrusion 113 on the inner wall of the plug cavity 111, and the protective cylinder 23 is inserted into the plug cavity 111 of the socket 11 until the sealing section 211 of the plug 21 is inserted to the bottom of the plug cavity 111. At this time, the pin 2211 of the second plug part 221 is inserted into the socket 1211 of the first plug part 121 to complete the electrical connection, and the sealing member 30 is in close contact with the inner wall of the sealing cavity 112.

[0083] Then, rotate the connecting sleeve 13 to make the external thread of the connecting sleeve 13 and the connecting section 213 of the plug 21 threaded together, which can prevent the socket 11 and the plug 21 from loosening and separating.

[0084] After the first insertion assembly 10 and the second insertion assembly 20 are inserted, the gear ring 44 is rotated by rotating the adjusting member 42. Since the gear ring 44 meshes with multiple first gears 433, it drives the threaded sleeve 432 to rotate synchronously. Since the threaded sleeve 432 is threadedly connected to the lead screw 431 and the lead screw 431 is fixedly connected to the pressure ring 41, the threaded engagement between the threaded sleeve 432 and the lead screw 431 converts the rotational motion of the threaded sleeve 432 into the linear motion of the lead screw 431. The lead screw 431 drives the pressure ring 41 to move, thereby changing the clamping force on the seal 30 and thus changing the compression ratio of the seal 30.

[0085] The electrical connector 100 of this embodiment can compensate for the dimensional tolerances of the plug 21 and the socket 11 by adjusting the compression amount of the sealing element 30 through the adjusting mechanism 40, so as to accommodate the different processing errors of the socket 11 and the plug 21. The compression amount of the sealing element 30 can be adjusted according to the usage conditions, and compensation can be made when the sealing performance of the sealing element 30 decreases. Moreover, the sealing element 30 is easy to replace without replacing the entire electrical connector 100, thus reducing maintenance costs. Therefore, the electrical connector 100 of this embodiment has the advantages of adjustable sealing performance, long-term reliability, and low maintenance costs.
