It should be noted that the first external device and the second external device can be electrical devices such as energy storage devices, new energy vehicles, etc.

[0058] For the above socket assembly 10, see Figure 3 The socket assembly 10 includes a mounting seat 11 and a first conductive column 12. The mounting seat 11 is provided with a mounting groove 11a, the mounting seat 11 is mounted on a first external device, and the first conductive column 12 is electrically connected to the first external device, for example, the first conductive column 12 and the first external device are respectively connected by a wire to realize current or electrical signal transmission between the socket assembly 10 and the first external device. In this embodiment, the first conductive column 12 is used to transmit current.

[0059] In some embodiments, there are multiple first conductive pillars 12 , and the multiple first conductive pillars 12 are arranged at intervals.

[0060] The socket assembly 10 further includes a first signal column 13, which is disposed in the mounting groove 11a, and is spaced apart from the first conductive column 12. The first signal column 13 is electrically connected to the first external device, for example, by connecting the first signal column 13 and the first external device respectively through a wire to achieve current or electrical signal transmission between the socket assembly 10 and the first external device. In this embodiment, the first signal column 13 is used to transmit electrical signals.

[0061] In some embodiments, there are multiple first signal pillars 13 , and the multiple first signal pillars 13 are arranged at intervals.

[0062] See also Figure 3-Figure 4 The mounting seat 11 is also provided with a card slot 11b, which is located on the outer surface of the mounting seat 11 and extends along the plugging direction. The card slot 11b has a first side wall 11b1 and a second side wall 11b2 opposite to each other, and a convex portion 111 is extended from the first side wall 11b1 to the second side wall 11b2, and a second opening 11b3 is formed between the convex portion 111 and the second side wall 11b2.

[0063] In some embodiments, the protrusion 111 is provided with a first guide inclined surface 111a, and the first guide inclined surface 111a is used to guide the clamping portion 211 to align with the second opening 11b3, so that the plug assembly 20 can be plugged into the socket assembly 10 more smoothly, thereby improving the user experience.

[0064] See also Figure 5-Figure 6 A first insulating portion 112 protrudes from the bottom wall of the mounting groove 11a. A first insulating hole 112a is formed on the end surface of the first insulating portion 112 along the direction of the socket assembly 10 toward the plug assembly 20. The first conductive column 12 is located in the first insulating hole 112a. The side wall of the first insulating hole 112a has insulating properties to reduce the contact between the first conductive column 12 and external objects, thereby reducing the risk of electric shock.

[0065] The bottom wall of the mounting groove 11a also protrudes with a second insulating portion 113, and the first insulating portion 112 and the second insulating portion 113 are arranged at intervals. Along the direction of the socket assembly 10 toward the plug assembly 20, the end surface of the second insulating portion 113 is provided with a second insulating hole 113a, and the first signal column 13 is located in the second insulating hole 113a. The side wall of the second insulating hole 113a has insulating properties to reduce the contact between the first signal column 13 and external objects, thereby reducing the risk of electric shock. In addition, the height of the first signal column 13 is less than the depth of the second insulating hole 113a, which further increases the creepage distance of the first signal column 13.

[0066] The first conductive column 12 is made of a conductor with conductive properties, for example, the first conductive column 12 is made of copper. A first conductive hole 12 b is disposed at the end of the first conductive column 12 from the socket assembly 10 toward the plug assembly 20 .

[0067] The first signal column 13 is also made of a conductor with conductive properties, for example, the first signal column 13 is made of copper. A second conductive hole 13a is provided at the end of the first signal column 13 along the direction from the socket assembly 10 to the plug assembly 20. Figure 8 The first signal column 13 includes a column portion 131, a first elastic portion 132 and a second elastic portion 133. The first elastic portion 132 and the second elastic portion 133 are spaced apart at the other end of the column portion 131. The second conductive hole 13a extends from the gap between the first elastic portion 132 and the second elastic portion 133 to the column portion 131, and the first elastic portion 132 is inclined toward the second elastic portion 133, and the second elastic portion 133 is inclined toward the first elastic portion 132, so that the cross-section of the second conductive hole 13a gradually decreases from the column portion 131 toward the first elastic portion 132 or the second elastic portion 133.

[0068] See also Figure 4 , and combined with Fig. 9The socket assembly 10 further includes a bracket 14, which is made of insulating material. The bracket 14 is mounted on the mounting seat 11, and the bracket 14 is used to support and limit the first conductive column 12 and the first signal column 13, so that the first conductive column 12 and the first signal column 13 are locked relative to the mounting seat 11. Specifically, the mounting seat 11 is provided with a mounting hole 11d adapted to the bracket 14, and the side wall of the mounting hole 11d is provided with a snap-fit ​​hole 11e, and the outer surface of the bracket 14 is provided with a snap-fit ​​portion 14a, and the bracket 14 is inserted into the mounting hole 11d, and the snap-fit ​​portion 14a is inserted into the snap-fit ​​hole 11e, so that the bracket 14 is locked relative to the mounting seat 11.

[0069] The bracket 14 is also provided with a first supporting hole 14b, and the first conductive column 12 is provided with a first step 12c protruding along its radial direction. Part of the first conductive column 12 is inserted into the first supporting hole 14b, and one end of the first step 12c is abutted against the hole opening of the first supporting hole 14b, and the other end of the first step 12c is abutted against the mounting seat 11. It can be understood that the mounting seat 11 and the bracket 14 jointly clamp the first step 12c, so that the first conductive column 12 is locked relative to the mounting seat 11.

[0070] The bracket 14 is provided with a second supporting hole 14c, and the first signal column 13 is provided with a second step 13b protruding along its radial direction. Part of the first signal column 13 is inserted into the second supporting hole 14c, and one end of the second step 13b is abutted against the hole opening of the second supporting hole 14c, and the other end of the second step 13b is abutted against the mounting seat 11. It can be understood that the mounting seat 11 and the bracket 14 jointly clamp the second step 13b, so that the first signal column 13 is locked relative to the mounting seat 11.

[0071] In some embodiments, the mounting seat 11 is provided with a positioning column 114, and a positioning groove 14d is provided on the outer surface of the bracket 14. When the bracket 14 is mounted on the mounting seat 11, the positioning column 114 is inserted into the positioning groove 14d to play a positioning role.

[0072] In some embodiments, the mounting seat 11 is further provided with a guide portion 115, the guide portion 115 extends along the axial direction of the mounting hole 11d, and the guide portion 115 is aligned with the positioning column 114, that is, the line connecting the guide portion 115 and the positioning column 114 is parallel to the axial direction of the mounting hole 11d. The positioning groove 14d extends along the axial direction of the bracket 14 to form a guide groove. When the bracket 14 is inserted into the mounting hole 11d, the guide portion 115 corresponds to the guide groove, and the guide portion 115 is inserted into the guide groove. The guide portion 115 also has a limiting function, that is, the bracket 14 cannot rotate relative to the mounting seat 11.

[0073] In some embodiments, the bracket 14 is provided with a partition 14 e . The partition 14 e is made of an insulating material. The partition 14 e is used to separate the first conductive column 12 and the first signal column 13 .

[0074] In some embodiments, the outer wall of the mounting seat 11 is provided with a first opening 11f, and the first opening 11f is connected to the mounting hole 11d, so that the side wall of the mounting hole 11d forms an elastic wall, and the snap-fit ​​hole 11e is provided on the elastic wall. When the bracket 14 is inserted into the mounting hole 11d, the elastic wall is elastically deformed, making it easier for the bracket 14 to be inserted into the mounting hole 11d. Optionally, there are multiple first openings 11f, and the multiple first openings 11f are arranged at intervals to form multiple elastic walls.

[0075] For the above-mentioned plug assembly 20, please refer to Figure 3-Figure 4 The plug assembly 20 includes a plug body 21 and a second conductive column 22. The second conductive column 22 is a conductor with conductive properties. The second conductive column 22 is disposed on the plug body 21, and the second conductive column 22 is electrically connected to a second external device. When the plug assembly 20 is plugged into the socket assembly 10, the first conductive column 12 is inserted into the first conductive hole 12b, and the second conductive column 22 elastically abuts against the side wall of the first conductive hole 12b, so that the first conductive column 12 is connected to the second conductive column 22, thereby reducing the risk of poor contact between the first conductive column 12 and the second conductive column 22, and further realizing current transmission between the socket assembly 10 and the plug assembly 20.

[0076] The plug assembly 20 further includes a second signal column 23, which is a conductor with conductive properties. The second signal column 23 is disposed on the plug body 21, and the second conductive column 22 and the second signal column 23 are disposed at intervals, and the second signal column 23 is electrically connected to the second external device. When the plug assembly 20 is plugged into the socket assembly 10, the second signal column 23 elastically abuts against the side wall of the second conductive hole 13a, and the first signal column 13 and the second signal column 23 are conductively connected, thereby reducing the risk of poor contact between the first signal column 13 and the second signal column 23, and realizing the transmission of electrical signals between the socket assembly 10 and the plug assembly 20.

[0077] For the above-mentioned plug body 21, please refer to Figure 3 , and combined with Fig.10The plug body 21 includes a plug seat body 212. Along the direction of the plug assembly 20 toward the socket assembly 10, the plug seat body 212 extends with a third insulating portion 213. The outer diameter of the third insulating portion 213 is adapted to the inner diameter of the mounting groove 11a. The third insulating portion 213 is provided with a third insulating hole 213a and a fourth insulating hole 213b. The second conductive column 22 is located in the third insulating hole 213a, and the second signal column 23 is located in the fourth insulating hole 213b. The side walls of the third insulating hole 213a and the side walls of the fourth insulating hole 213b are both insulating, thereby reducing the contact between the second conductive column 22 and external objects, thereby reducing the risk of electric shock and increasing the creepage distance between the second conductive column 22 and the second signal column 23. When the plug assembly 20 is plugged into the socket assembly 10, the third insulating portion 213 corresponds to the mounting groove 11a, the first insulating portion 112 corresponds to the third insulating hole 213a, the second insulating portion 113 corresponds to the fourth insulating hole 213b, and the first insulating portion 112 is inserted into the third insulating hole 213a, the second insulating portion 113 is inserted into the fourth insulating hole 213b, and the third insulating portion 213 is inserted into the mounting groove 11a.

[0078] In some embodiments, please refer to Figure 6 , and combined with Fig.10 The side wall of the third insulating hole 213a is recessed to form a slide groove 213c, and a slide portion 1121 protrudes from the outer surface of the first insulating portion 112. When the plug assembly 20 is plugged into the socket assembly 10, the slide portion 1121 is inserted into the slide groove 213c, and the slide portion 1121 can slide along the slide groove 213c, thereby limiting the rotation of the first insulating portion 112 relative to the third insulating hole 213a, and further limiting the rotation of the plug assembly 20 relative to the socket assembly 10. When the plug assembly 20 rotates relative to the socket assembly 10, the first conductive column 12 or the first signal column 13 that is not located in the installation groove 11a is likely to collide with the first insulating portion 112 and bend or break.

[0079] See also Fig.10 The plug body 21 is provided with a clamping portion 211. When the drive socket assembly 10 is plugged into the plug assembly 20, part of the plug body 21 extends into the mounting groove 11a, the first conductive column 12 abuts against the second conductive column 22, and the clamping portion 211 is snapped into the clamping groove 11b, so that the plug assembly 20 is locked relative to the socket assembly 10.

[0080] Please continue reading Fig.10The plug body 21 further includes a rotating sleeve 214 and an elastic member 215. The rotating sleeve 214 is in a hollow cylindrical shape, and is rotatably connected and sleeved on the plug seat 212. Part of the plug seat 212 is located in the rotating sleeve 214, and the rotating sleeve 214 can rotate relative to the plug seat 212. The clamping portion 211 is disposed on the rotating sleeve 214, and there is a gap between the plug body 21 and the rotating sleeve 214, and the gap is disposed around the rotation axis of the rotating sleeve 214. The elastic member 215 is disposed in the gap, and one end of the elastic member 215 is connected to the plug body 21, and the other end of the elastic member 215 is connected to the rotating sleeve 214. When the card portion 211 is engaged in the card slot 11b and under the action of the elastic member 215, the card portion 211 can remain against the side wall of the card slot 11b to reduce the risk of the plug assembly 20 being detached relative to the socket assembly 10. When the driving rotating sleeve 214 is driven to rotate relative to the plug seat body 212, the external force overcomes the elastic force of the elastic member 215 to make the card portion 211 detach from the side wall of the card slot 11b, thereby realizing the plug assembly 20 being pulled out relative to the socket assembly 10.

[0081] In some embodiments, the third insulating portion 213 has an extending portion 21 b extending toward the rotating sleeve 214 , and the extending portion 21 b , the third insulating portion 213 and the rotating sleeve 214 form a receiving cavity 21 c , and the elastic member 215 is disposed in the receiving cavity 21 c .

[0082] When the plug assembly 20 is plugged into the socket assembly 10, the first conductive column 12 of the plug assembly 20 is pre-aligned with the second conductive column 22, and the first signal column 13 is pre-aligned with the second signal column 23, that is, the third insulating portion 213 corresponds to the mounting groove 11a, the first insulating portion 112 corresponds to the third insulating hole 213a, and the second insulating portion 113 corresponds to the fourth insulating hole 213b. When the first conductive column 12 is aligned with the second conductive column 22, and the first signal column 13 is aligned with the second signal column 23, the clamping portion 211 is aligned with the protrusion 111, that is, the line connecting the clamping portion 211 and the protrusion 111 is parallel to the plug-in direction, and the plug assembly 20 is driven to move toward the socket assembly 10 by applying an external force until the clamping portion 211 abuts against the protrusion 111. When the plug assembly 20 is driven to move toward the socket assembly 10, the protrusion 111 squeezes the clamping portion 211, so that the protrusion 111 applies a reaction force to the clamping portion 211, and the protrusion 111 pushes the clamping portion 211, and the rotating sleeve 214 rotates from the first preset position to the second preset position, and the elastic member 215 is compressed. The first elastic force generates an elastic force. When the protrusion 111 is aligned with the second opening 11b3, that is, the line connecting the protrusion 111 and the second opening 11b3 is parallel to the plugging direction, the plug assembly 20 is continuously driven to move toward the socket assembly 10, and the clamping portion 211 abuts against the bottom of the clamping slot 11b, and the bottom of the clamping slot 11b has a limiting effect on the clamping portion 211. Under the elastic force of the first elastic force, the first elastic force drives the rotating sleeve 214 to rotate relative to the plug body 21, and the clamping portion 211 abuts against the side wall of the clamping slot 11b, and the protrusion 111 is aligned with the protrusion 111 again, thereby realizing that the plug assembly 20 is locked relative to the socket assembly 10. When the plug assembly 20 is locked relative to the socket assembly 10, by pulling out the plug assembly 20 in a direction away from the socket assembly 10, the protrusion 111 has a limiting effect on the clamping portion 211, so that the plug assembly 20 cannot be pulled out relative to the socket assembly 10.

[0083] Compared with the prior art, even if the plug assembly 20 is vibrated or impacted, the plug assembly 20 cannot be pulled out relative to the socket assembly 10, thereby reducing the risk of the plug assembly 20 being detached from the socket assembly 10 when power is on, further reducing the risk of electric shock, and improving the safety factor.

[0084] In some embodiments, see Figure 3 , and combined with Fig.11The plug assembly 20 also includes a bolt 24. The plug body 21 is provided with a through hole 21d. The bolt 24 passes through the through hole 21d and is screwed to the first external device, so that the plug assembly 20 is locked to the first external device, thereby reducing the risk of the plug assembly 20 being detached from the socket assembly 10 when power is on, and further reducing the risk of electric shock. Specifically, the bolt 24 includes a nut 241, a rod 242 and a threaded portion 243. The rod 242 is adapted to the through hole 21d. One end of the rod 242 passes through the through hole 21d and is connected to the threaded portion 243. The nut 241 is connected to the other end of the rod 242. The diameter of the rod 242 is smaller than the diameter of the nut 241 and the diameter of the threaded portion 243, so that the two opposite openings of the through hole 21d are formed with a first limiting step 21d1 and a second limiting step 21d2. The first limiting step 21d1 is used to limit the movement of the nut 241 toward the threaded portion 243, and the second limiting step 21d2 is used to limit the movement of the threaded portion 243 toward the nut 241 to prevent the bolt 24 from falling off or falling relative to the plug body 21.

[0085] In some embodiments, please refer to Fig.11 The rotating sleeve 214 has a protruding portion 2142 extending in the radial direction, and the through hole 21d is disposed on the protruding portion 2142. When the rotating sleeve 214 is located at the first preset position, the through hole 21d is misaligned with the screw hole of the first external device. When the rotating sleeve 214 rotates from the first preset position to the second preset position, the through hole 21d is aligned with the screw hole of the first external device. In other words, when the clamping portion 211 is aligned with the second opening 11b3 or snapped into the clamping groove 11b, the bolt 24 can be screwed into the screw hole of the first external device, so that the socket assembly 10 and the plug assembly 20 are doubly locked.

[0086] In some embodiments, the plug assembly 20 also includes a first elastic structure 25, one end of the first elastic structure 25 is connected to the plug body 21, and the other end of the first elastic structure 25 abuts against the nut 241 of the bolt 24. The first elastic structure 25 is used to maintain abutment with the bolt 24. The first elastic structure 25 maintains applying elastic force to the nut 241 of the bolt 24 to prevent the bolt 24 from loosening when locked relative to the first external device.

[0087] Please refer to Figure 6 and Figure 7 The plug assembly 20 also includes an elastic sleeve 26, the outer wall of the elastic sleeve 26 elastically abuts against the inner wall of the first conductive hole 12b.

[0088] In some embodiments, the elastic sleeve 26 includes a plurality of elastic arms 261 and an elastic hoop 262, and the plurality of elastic arms 261 are connected to the elastic hoop 262. Along the axial direction of the elastic hoop 262, the elastic hoop 262 is provided with an opening 262a, and the opening 262a penetrates the elastic hoop 262, so that the elastic hoop 262 forms a first elastic portion 262b and a second elastic portion 262c, and the opening 262a provides a deformation space for the first elastic portion 262b and the second elastic portion 262c, and the first elastic portion 262b and the second elastic portion 262c maintain a tendency to move in opposite directions, so that the elastic hoop 262 elastically abuts against the inner wall of the first conductive slot. The plurality of elastic arms 261 are arranged at intervals along the circumference of the elastic hoop 262, and the plurality of elastic arms 261 are inclined toward the central axis of the elastic hoop 262, and the plurality of elastic arms 261 are used to clamp the second conductive column 22.

[0089] In some embodiments, a groove 112b is formed in the side wall of the first insulating hole 112a, and the elastic sleeve 26 is disposed in the groove 112b, and the groove 112b is used to install the elastic sleeve 26. Of course, two spaced limiting portions may be protruded from the side wall of the first insulating hole 112a, and the elastic sleeve 26 is disposed between the two limiting portions, and the two limiting portions have a limiting effect on the elastic sleeve 26.

[0090] In some other embodiments, the number of the elastic hoop 262 is two, one elastic hoop 262 is disposed at one end of the plurality of elastic arms 261 , and the other elastic hoop 262 is disposed at the other end of the plurality of elastic arms 261 .

The plug assembly 20 also includes a sealing ring 28, which is arranged in the sealing groove 21a, and part of the sealing ring 28 protrudes from the sealing groove 21a. The sealing ring 28 protruding from the sealing groove 21a is used to abut against the side wall of the installation groove 11a to prevent dust or rainwater from entering the first insulating hole 112a, the second insulating hole 113a, the third insulating hole 213a and the fourth insulating hole 213b, thereby reducing the risk of short circuit of the first conductive column 12 or the first signal column 13.

[0092] In some embodiments, please refer to Fig.10 The card portion 211 is provided with a second guide inclined surface 211a, and the second guide inclined surface 211a is used to guide the card portion 211 to align with the second opening 11b3, so that the plug assembly 20 is plugged into the socket assembly 10 more smoothly, thereby improving the user experience.

In addition, the end face of the anti-touch portion 271 is provided with a guide bevel, and the guide bevel is rounded. The guide bevel is used to guide the second conductive column 22 to be inserted into the first conductive hole 12b of the first conductive column 12.

[0095] In an embodiment of the present application, a connector 100 is provided. The connector 100 includes a socket assembly 10 and a plug assembly 20. The socket assembly 10 includes a mounting seat 11 and a first conductive column 12. The mounting seat 11 is provided with a mounting groove 11a. The first conductive column 12 is arranged in the mounting groove 11a. The mounting seat 11 is used to be installed on a first external device. The first conductive column 12 is used to be electrically connected to the first external device. The plug assembly 20 includes a plug body 21, a second conductive column 22 and a bolt 24. The second conductive column 22 is arranged on the plug body 21. The first conductive column 12 corresponds to the second conductive column 22. The second conductive column 22 is used to be electrically connected to the second external device. The plug body 21 is provided with a through hole 21d. The bolt 24 passes through the screw hole and is screwed to the screw hole of the first external device, thereby reducing the risk of the plug assembly 20 being detached from the socket assembly 10 when power is on, further reducing the risk of electric shock, and improving the safety factor.

[0096] See also Figure 20-23The present invention also provides an embodiment of an energy storage device 200, which includes a housing 2001, a micro switch 2002, a controller (not shown) and the above-mentioned connector 100. The micro switch 2002, the controller and the mounting seat 11 are all arranged in the housing 2001, and the micro switch 2002 and the socket assembly 10 are both electrically connected to the controller. When the bolt 24 is aligned with the screw hole 200b of the shell 2001, the micro switch 2002 is aligned with the bolt 24, and the bolt 24 passes through the through hole 21d and is screwed into the screw hole 200b of the shell 2001, so that the plug assembly 20 is locked relative to the shell 2001, and the bolt 24 is against the micro switch 2002. The controller controls the energy storage device 200 and the plug assembly 20 to switch from a power-off state to a power-on state. When the bolt 24 is disengaged from the micro switch 2002, the controller controls the energy storage device 200 and the plug assembly 20 to switch from a power-on state to a power-off state. When a user pulls out the plug assembly 20, the micro switch 2002 controls the current between the socket assembly 10 to stop transmitting, thereby improving the safety of the connector 100 and reducing the risk of electric shock.

[0097] The micro switch 2002 includes a base (not shown) and a telescopic rod (not shown), the base is fixed to the housing 2001, the telescopic rod is slidably connected to the base, and the base is provided with a first conductive part, the telescopic rod is provided with a second conductive part, the controller is electrically connected to the first conductive part and the second conductive part respectively, the telescopic rod is used to be driven by the bolt 24, and drives the telescopic rod to move relative to the base, so that the first conductive part and the second conductive part are abutted or separated. When the first external device and the plug assembly 20 are in a power-on state, the first conductive part and the second conductive part are abutted, and when the first external device and the plug assembly 20 are in a power-off state, the first conductive part and the second conductive part are separated.

[0098] In some embodiments, the micro switch 2002 further includes a second elastic structure (not shown), one end of the second elastic structure is connected to the base, and the other end of the second elastic structure is connected to the telescopic rod. This reduces the risk of the telescopic rod moving toward the base due to its own gravity, and can also improve the sensitivity of the telescopic rod. When the bolt 24 drives the telescopic rod to move toward the base, the second elastic structure generates an elastic force, and the elastic force of the second elastic structure resists the bolt 24 from moving toward the base. When the bolt 24 drives the telescopic rod to move away from the base, the elastic force of the second elastic structure drives the telescopic rod to reset.
