[0001] This application relates to the technical field of electrical connection, and particularly to a first connection structure of a connector, a connector, and an energy storage device. Background Art

[0002] A connector generally includes a first connection structure and a second connection structure. The first connection structure includes a housing, a buckle, and a button assembly linked with the buckle. The second connection structure is formed with a buckle groove matching the buckle. When the first connection structure is inserted into the second connection structure, it is necessary to press the button assembly to cause the button assembly to retract towards the interior of the housing, so as to drive the buckle to tilt upwards away from the housing. After the first connection structure is completely inserted into the second connection structure, release the button assembly to release the buckle, and the buckle snaps into the buckle groove to lock the first connection structure on the second connection structure, thereby preventing the first connection structure and the second connection structure from falling off.

[0003] However, after the first connection structure is inserted into the second connection structure, the button assembly may be accidentally touched, and the button assembly drives the buckle to tilt upwards, resulting in the buckle falling off from the buckle groove, and further causing the connection between the first connection structure and the second connection structure to be disconnected, resulting in the failure of the connector connection.

[0047] Please refer to Figures 1 to 3 , the present application provides a first connection structure 100 of a connector 1000. The first connection structure 100 includes a housing 10, a buckle assembly 30, a button assembly 50, and a slider 70. A guide member 11 is provided inside the housing 10. The buckle assembly 30 is rotatably mounted on the housing 10. The button assembly 50 is connected to the buckle assembly 30 and includes a portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, it can move along the first direction Z to drive the buckle assembly 30 to rotate relative to the housing 10. The slider 70 includes a locking portion 71. The slider 70 is mounted on the guide member 11 and can move relative to the guide member 11 along a second direction X, and the first direction Z is perpendicular to the second direction X. When the slider 70 moves relative to the guide member 11 along the second direction X until the locking portion 71 abuts against the portion to be locked 511, the movement of the button assembly 50 along the first direction Z is restricted; when the slider 70 moves relative to the guide member 11 along the second direction X until the locking portion 71 disengages from the portion to be locked 511, the force can cause the button assembly 50 to move along the first direction Z.

[0048] Specifically, the connector 1000 includes a first connection structure 100, a second connection structure 300, and a connection line 500. The second connection structure 300 includes a buckle groove 301. The buckle groove 301 is connected to the buckle assembly 30, and the connection line 500 is connected to the housing 10. Please refer to Figure 11, when using the connector 1000, after connecting the second connection structure 300 of the connector 1000 to the first component to be connected (such as the energy storage battery 3000), connect the second connection structure 300 to the housing 10 of the first connection structure 100. The housing 10 contains electrical connectors (not shown) so that the energy storage battery 3000 and the electrical connectors form an electrical connection. The snap groove 301 is connected to the snap component 30 to further fix the second connection structure 300 and the first connection structure 100. One end of the connection line 500 is connected to the housing 10, and the other end is connected to the second component to be connected, such as the circuit board 5000 of the Battery Management System (BMS). Thus, a circuit path from the energy storage battery 3000, through the electrical connectors, the connection line 500 to the circuit board 5000 can be formed to realize the management of the energy storage battery 3000 by the battery management system. After the electrical connection of the connector 1000 is completed, the connection between the snap groove 301 and the snap component 30 can fix the second connection structure 300 and the housing 10. However, in some cases, the button may be accidentally touched, causing the snap component to disengage from the snap groove after the button is subjected to a force in the first direction Z, resulting in the failure of the connection between the second connection structure and the housing.

[0049] In this application, the first direction Z is the height direction of the connector 1000, the second direction X is the length direction of the connector 1000, and the third direction Y is the width direction Y of the connector 1000.

[0050] The housing 10 is a structure for installing other components of the connector 1000 and accommodating other components inside the housing 10. The housing 10 can be an integral structure or a split structure. The housing 10 of this application is a split structure, and the housing 10 includes a first housing 13 and a second housing 14. The cross-sectional shape of the first housing 13 can be, but is not limited to, circular, elliptical, rectangular, or other polygons, etc. The cross-sectional shape of the first housing 13 in this application is rectangular. The material of the first housing 13 can be plastic, metal, etc. When the material of the first housing 13 is plastic, the first housing 13 has good insulation performance, low cost, and light weight. When the material of the first housing 13 is metal, the first housing 13 has high strength, good wear resistance, and long service life.

[0051] The second housing 14 is used to install the electrical connector, and at least part of the electrical connector is received inside the second housing 14 to protect the electrical connector. The cross-sectional shape of the second housing 14 is the same as that of the first housing 13 to facilitate the combination of the second housing 14 and the first housing 13. The material of the second housing 14 is the same as that of the first housing 13. The electrical connector is made of a conductive material, and the conductive material includes but is not limited to metals, graphite, conductive polymers, oxides, or carbon nanotubes, etc. Among them, the metals include but are not limited to copper, aluminum, silver, gold, and nickel, etc.; the oxides include but are not limited to copper oxide, zinc oxide, and magnesium oxide, etc.

[0052] The button assembly 50 is provided on the housing 10. The user can press the button assembly 50 to retract the button assembly 50 into the housing 10, thereby driving the buckle assembly 30 to tilt upward. Among them, the direction in which the user presses the button assembly 50 is the first direction Z. The button assembly 50 can be one or more. The button 51 can be provided on any side wall surrounding the second connection structure 300, that is, the button assembly 50 can be provided on two side walls in the first direction Z (such as the second wall 105) and two side walls in the second direction X. In this application, the button assembly 50 is one. More specifically, when the first connection structure 100 and the second connection structure 300 are connected, the user presses the button assembly 50, so that the button assembly 50 receives a force in the first direction Z and moves along the first direction Z, that is, the button assembly 50 retracts into the housing 10, so as to drive the end of the buckle 31 of the buckle assembly 30 provided with the tongue 3111 to rotate away from the housing 10, that is, the end of the buckle assembly 30 provided with the tongue 3111 tilts upward, so that the first connection structure 100 can be inserted into the second connection structure 300 and the tongue 3111 is opposite to the buckle groove 301 in the first direction Z. After the first connection structure 100 is completely inserted into the second connection structure 300, the button assembly 50 is released to release the buckle 31, and the end of the buckle 31 provided with the tongue 3111 rotates toward the housing 10 to snap into the buckle groove 301. Thus, the buckling of the buckle 31 and the buckle groove 301 forms a firm connection between the first connection structure 100 and the second connection structure 300, thereby preventing the first connection structure 100 and the second connection structure 300 from falling off.

[0053] The guide member 11 is provided in the housing 10. Preferably, the guide member 11 is provided on the first housing 13 to avoid interference with the electrical connector. The guide member 11 can be provided on any side wall of the first housing 13 different from the side wall where the button assembly 50 is provided. The guide member 11 can be one or more, and multiple guide members 11 can be provided on one side wall. The guide member 11 is used to enable the sliding member 70 to slide along it, that is, the guide member 11 is used to guide the sliding of the sliding member 70 to make the sliding of the sliding member 70 more stable and smooth.

[0054] The first connection structure 100 of the embodiment of the present application is provided with a guide member 11 and a sliding member 70. When the button assembly 50 does not need to move along the first direction Z, the sliding member 70 moves relative to the guide member 11 along the second direction X to a position where the locking portion 71 abuts against the portion to be locked 511, restricting the movement of the button assembly 50 along the first direction Z. Thus, it is avoided that the button assembly 50 is accidentally touched when it does not need to be pressed, which may cause the button assembly 50 to drive the buckle assembly 30 to rotate. Thereby, the connection stability between the buckle assembly 30 and the components connected thereto can be ensured. When the button assembly 50 needs to move along the first direction Z, the sliding member 70 moves relative to the guide member 11 along the second direction X to a position where the locking portion 71 disengages from the portion to be locked 511, ensuring that the button assembly 50 can move along the first direction Z.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, the guide member 11 is a guide cavity 110, and the housing 10 further includes a fixing member 15. The fixing member 15 is located inside the first housing 13 and is connected to the first housing 13 to form the guide cavity 110, and the sliding member 70 is movably received in the guide cavity 110.

[0056] Specifically, the housing 10 includes a first housing 13, a second housing 14, and a fixing member 15 provided on the first housing 13. In some embodiments, the first housing 13 and the fixing member 15 are an integral structure, that is, the first housing 13 and the fixing member 15 are a whole structure, which can improve the bonding strength between the first housing 13 and the fixing member 15, prevent the first housing 13 and the fixing member 15 from separating during the operation of the housing 10, and thus ensure the stability and reliability of the operation of the housing 10. In other embodiments, the first housing 13 and the fixing member 15 are a split structure, that is, the first housing 13 and the fixing member 15 are two different structures. In one example, the first housing 13 and the fixing member 15 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or screw connection, etc. In another example, the first housing 13 and the fixing member 15 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc.

[0057] In an embodiment of the present application, the first housing 13 and the fixing member 15 are of a detachable structure. The fixing member 15 is provided with bolt holes arranged along the second direction X to fix the fixing member 15 to the first housing 13 through bolts and be spaced from the first housing 13. The detachable structure design facilitates the disassembly and assembly of the first housing 13 and the fixing member 15, and also facilitates the removal of the sliding member 70. The first housing 13 and the fixing member 15 are spaced in the third direction Y to form a guiding cavity 110, and the guiding cavity 110 is located inside the housing 10. The guiding cavity 110 is used to accommodate the sliding member 70, enabling the sliding member 70 to move within the guiding cavity 110 while not falling off from the guiding cavity 110. It can be understood that in the second direction X, the size of the guiding cavity 110 is larger than that of the sliding member 70, thereby enabling the sliding member 70 to move in the second direction X.

[0058] The fixing member 15 is located inside the first housing 13 and is connected to the first housing 13 to form the guiding cavity 110, which can accommodate the sliding member 70, provide an installation space for the sliding member 70, sandwich the sliding member 70 between the first housing 13 and the fixing member 15, prevent it from falling out of the housing 10, and eliminate the need for an installation component, saving parts. The sliding member 70 is movably accommodated in the guiding cavity 110, enabling the sliding member 70 to move within the guiding cavity 110.

[0059] Please continue to refer to Figure 2 、 Figure 3 and Figure 5 In some embodiments, a groove 131 is provided on the inner wall 101 of the first housing 13. The sliding member 70 further includes a sliding portion 73. The locking portion 71 protrudes and extends from the sliding portion 73. The sliding portion 73 is movably accommodated in the groove 131. The fixing member 15 is installed on the inner wall 101 of the housing 10 and partially covers the groove 131 to block the sliding portion 73. The fixing member 15 is provided with a notch 151, and the locking portion 71 is accommodated in the notch 151. The guiding cavity 110 includes the groove 131 and the notch 151.

[0060] Specifically, a groove 131 is provided on the inner wall 101 of the first housing 13. The groove 131 can be formed by the depression of the inner wall 101 of the first housing 13, or can be formed by enclosing a groove 131 with one or more protrusions extending into the first housing 13 on the inner wall 101. The sliding portion 73 is accommodated in the groove 131, and the inner wall 101 of the groove 131 can limit the movement positions of the sliding portion 73 in the first direction Z and the second direction X, enabling the sliding portion 73 to move within the groove 131 without falling off in the first direction Z and the second direction X. The fixing member 15 partially covers the groove 131, which can block the sliding portion 73 from falling off in the third direction Y. In this way, the fixing member 15 is installed on the inner wall 101 of the housing 10, enabling the sliding portion 73 to be accommodated in the groove 131 and preventing the sliding portion 73 from falling off.

[0061] The fixing member 15 is provided with a notch 151 for accommodating the locking portion 71. The notch 151 and the groove 131 are oppositely arranged and communicated in the third direction Y to jointly form a guiding cavity 110. The locking portion 71 protrudes and extends from the sliding portion 73 in the third direction Y. Thus, the locking portion 71 can be accommodated in the notch 151, and the sliding portion 73 can be accommodated in the groove 131. The locking portion 71 and the sliding portion 73 are of an integral structure, thereby improving the bonding strength between the locking portion 71 and the sliding portion 73, preventing the locking portion 71 and the sliding portion 73 from separating during the operation of the sliding member 70, and thus ensuring the stability and reliability of the operation of the sliding member 70. When the sliding member 70 moves relative to the guiding member 11 in the second direction X, the sliding portion 73 moves in the groove 131 in the second direction X, and the locking portion 71 moves in the notch 151 in the second direction X. The locking portion 71 and the to-be-locked portion 511 are in contact at some positions (i.e., when the sliding member 70 is in the first extreme position M). Thus, when the button 51 is subjected to a force in the first direction Z and the to-be-locked portion 511 moves in the direction close to the locking portion 71, the locking portion 71 can provide a supporting force for the to-be-locked portion 511 to limit the movement of the to-be-locked portion 511 in the first direction Z.

[0062] Please refer to Figure 4 , Figure 5 and Figure 7 , in some embodiments, the groove 131 includes opposite first side wall 1311 and second side wall 1312 in the second direction X. When the sliding portion 73 abuts against the first side wall 1311, the sliding member 70 is in the first extreme position M, and the movement of the button assembly 50 in the first direction Z is restricted, as Figure 7 shown; when the sliding portion 73 abuts against the second side wall 1312, the sliding member 70 is in the second extreme position N, and the acting force can make the button assembly 50 move in the first direction Z, as Figure 5 shown.

[0063] Specifically, one end of the sliding portion 73 close to the first side wall 1311 is the first end 731 of the sliding portion, and one end of the sliding portion 73 close to the second side wall 1312 is the second end 733 of the sliding portion. The sliding portion 73 can move between the first side wall 1311 and the second side wall 1312 in the second direction X. That is, the first side wall 1311 is used to limit the sliding portion 73 from moving in the direction (positive direction) close to the first side wall 1311 in the second direction X, and the second side wall 1312 is used to limit the sliding portion 73 from moving in the direction (reverse direction) close to the second side wall 1312 in the second direction X. When the first end 731 of the sliding portion abuts against the first side wall 1311, the slider 70 is in the first limit position M, and the sliding portion 73 cannot continue to move forward in the second direction X. At this time, the locking portion 71 abuts against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the locking portion 71 can provide a supporting force for the portion to be locked 511 to limit the movement of the portion to be locked 511 in the first direction Z, thereby restricting the relative rotation of the buckle assembly 30 with respect to the housing 10. When the second end 733 of the sliding portion abuts against the second side wall 1312, the slider 70 is in the second limit position N, and the sliding portion 73 cannot continue to move in the reverse direction in the second direction X. At this time, the locking portion 71 does not abut against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the portion to be locked 511 can move in the first direction Z to drive the buckle assembly 30 to rotate relative to the housing 10.

[0064] Please refer to Figure 5 , in some embodiments, the notch 151 includes opposite first inner wall 1511 and second inner wall 1512 in the second direction X. When the locking portion 71 abuts against the second inner wall 1512, the slider 70 is in the second limit position N, and the acting force can cause the button assembly 50 to move in the first direction Z.

[0065] Specifically, one end of the locking portion 71 close to the first inner wall 1511 is the first end 711 of the locking portion, and one end of the locking portion 71 close to the second inner wall 1512 is the second end 713 of the locking portion. The locking portion 71 can move within the notch 151. Among them, the second inner wall 1512 is used to limit the locking portion 71 from moving in the direction (positive direction) close to the second inner wall 1512 in the second direction X. When the second end 713 of the locking portion abuts against the second inner wall 1512, the slider 70 is in the second limit position N, and the locking portion 71 cannot continue to move forward in the second direction X. At this time, the locking portion 71 does not abut against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the portion to be locked 511 can move in the first direction Z to drive the buckle assembly 30 to rotate with respect to the housing 10.

[0066] In some embodiments, the first inner wall 1511 is configured to restrict the locking portion 71 from moving in the second direction X towards the direction (reverse direction) close to the first inner wall 1511. When the locking portion 71 abuts against the first inner wall 1511, the slider 70 is in the first extreme position M, and the movement of the button assembly 50 in the first direction Z is restricted. When the first end 711 of the locking portion abuts against the first inner wall 1511, the slider 70 is in the first extreme position M, and the locking portion 71 cannot continue to move in the reverse direction of the second direction X. At this time, the locking portion 71 abuts against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the locking portion 71 can provide a supporting force for the portion to be locked 511 to restrict the movement of the portion to be locked 511 in the first direction Z, thereby restricting the rotation of the snap component 30 relative to the housing 10.

[0067] Please refer to Figure 9 and Figure 10 , in some embodiments, the guiding member 11 is a guide rail 117 extending in the second direction X. The guide rail 117 is a protruding structure provided on the housing 10, and the slider 70 is movably sleeved on the guide rail 117.

[0068] Specifically, the guiding member 11 may be a protruding structure formed by the inner wall 101 of the housing 10 protruding and extending towards the inside of the housing 10. The guide rail 117 may be one or more. The slider 70 is sleeved on the guide rail 117 and can move in the second direction X. The movement of the slider 70 on the guide rail 117 can be linear or curved.

[0069] As a part of the housing 10, the guide rail 117 can ensure the connection stability between the guide rail 117 and the housing 10, which helps to maintain the rigidity and durability of the overall assembly.

[0070] Please continue to refer to Figure 9 and Figure 10 , in some embodiments, the guide rail 117 is provided with a first limiting portion 1171 and a second limiting portion 1173. When the slider 70 abuts against the first limiting portion 1171, the slider 70 is in the first extreme position, and the movement of the button assembly 50 in the first direction Z is restricted; when the slider 70 abuts against the second limiting portion 1173, the slider 70 is in the second extreme position, and a force can cause the button assembly 50 to move in the first direction Z.

[0071] Specifically, one end of the slider 70 close to the first limiting portion 1171 is the first end 711 of the slider 70, and one end of the slider 70 close to the second limiting portion 1173 is the second end 713 of the slider 70. The slider 70 can move between the first limiting portion 1171 and the second limiting portion 1173 in the second direction X. That is, the first limiting portion 1171 is used to limit the slider 70 from moving in the second direction X towards the direction (positive direction) close to the first limiting portion 1171, and the second limiting portion 1173 is used to limit the slider 70 from moving in the second direction X towards the direction (reverse direction) close to the second limiting portion 1173. When the first end 711 of the slider 70 abuts against the first limiting portion 1171, the slider 70 is in the first extreme position M, and the slider 70 cannot continue to move in the positive direction of the second direction X. At this time, the slider 70 abuts against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the slider 70 can provide a supporting force for the portion to be locked 511 to limit the movement of the portion to be locked 511 in the first direction Z, thereby restricting the rotation of the buckle assembly 30 relative to the housing 10. When the second end 713 of the slider 70 abuts against the second limiting portion 1173, the slider 70 is in the second extreme position N, and the slider 70 cannot continue to move in the positive direction of the second direction X. At this time, the slider 70 does not abut against the portion to be locked 511. When the button assembly 50 is subjected to a force in the first direction Z, the portion to be locked 511 can move in the first direction Z to drive the rotation of the buckle assembly 30 relative to the housing 10.

[0072] Please refer to Figure 2 and Figure 4 , in some embodiments, a through hole 1031 communicating with the groove 131 is formed in the first wall 103 of the housing 10. The slider 70 includes a side surface 75 facing the through hole 1031, and a locking mark 751 and an unlocking mark 753 are provided on the side surface 75. When the slider 70 is in the first extreme position M, the locking mark 751 is exposed from the through hole 1031, and the unlocking mark 753 is hidden inside the housing 10, as Figure 8 shown; when the slider 70 is in the second extreme position N, the unlocking mark 753 is exposed from the through hole 1031, and the locking mark 751 is hidden inside the housing 10, as Figure 6 shown.

[0073] Specifically, the through hole 1031 is a spatial structure for other components to extend into. The through hole 1031 penetrates the first wall 103, which can reduce the material used for the first wall 103, thereby reducing the weight of the housing 10. The cross-sectional shape of the through hole 1031 includes but is not limited to circular, oval, triangular, quadrilateral, racetrack-shaped, or other polygonal shapes, etc. In this application, the through hole 1031 is racetrack-shaped. The slider 70 covers the through hole 1031. When the slider 70 is in the first extreme position M, the locking mark 751 is exposed from the through hole 1031, and the unlocking mark 753 is hidden inside the housing 10, as Figure 8 shown; when the slider 70 is in the second extreme position N, the unlocking mark 753 is exposed from the through hole 1031, and the locking mark 751 is hidden inside the housing 10, as Figure 6 shown.

[0074] The display of the locking mark 751 and the unlocking mark 753 at different positions, that is, when the slider 70 is in the first extreme position M, the locking mark 751 is exposed from the through hole 1031, and the unlocking mark 753 is hidden inside the housing 10; when the slider 70 is in the second extreme position N, the unlocking mark 753 is exposed from the through hole 1031, and the locking mark 751 is hidden inside the housing 10. Thus, the user can intuitively identify the current state of the slider 70.

[0075] Please refer to Figure 2 , in some embodiments, the buckle assembly 30 includes a buckle member 31 and an elastic member 35. The buckle member 31 is rotatably connected to the inner wall 101 of the housing 10 through a connecting shaft 33. The buckle member 31 includes a first portion 311 and a second portion 313 on both sides of the connecting shaft 33. A tongue 3111 is provided at one end of the first portion 311 away from the second portion 313. The tongue 3111 is located outside the housing 10, and the second portion 313 is accommodated inside the housing 10. The elastic member 35 is sleeved on the connecting shaft 33. The elastic member 35 includes two opposite abutting ends 351 and an abutting section 353 located between the two abutting ends 351. The two abutting ends 351 abut against the housing 10, and the abutting section 353 is used to abut against the buckle member 31 and / or the button assembly 50.

[0076] Specifically, the movement directions of the first part 311 and the second part 313 are different. When the connector 1000 is installed, when the user applies a force in the first direction Z to the button 51, the button 51 drives the first part 311 and the second part 313 to rotate. Among them, the second part 313 abuts against the button 51 and rotates in the direction close to the inside of the housing 10, and the first part 311 rotates in the direction away from the inside of the housing 10, that is, the first part 311 tilts up, the second part 313 presses down, and the tongue 3111 corresponds to the buckle groove 301 in the first direction Z; after releasing the force on the button 51, the second part 313 rotates in the direction away from the housing 10, and the first part 311 rotates in the direction close to the inside of the housing 10, that is, the second part 313 tilts up, and after the first part 311 presses down, the tongue 3111 is snapped into the buckle groove 301, thereby connecting the second connection structure 300 and the housing 10.

[0077] The elastic member 35 is a telescopic structure. The elastic member 35 includes, but is not limited to, structures such as a spring or a torsion spring. In this application, the elastic member 35 is a torsion spring. The two abutting ends 351 of the elastic member 35 include a first abutting end 3511 and a second abutting end 3513. The first abutting end 3511 and the second abutting end 3513 are located at both ends of the connecting shaft 33 and abut against the housing 10 to fix the elastic member 35 and prevent relative displacement between the elastic member 35 and the housing 10. The abutting section 353 is located on the side of the second part 313 away from the button 51. When a first force in the second direction X is applied to the button 51, the button 51 drives the first part 311 and the second part 313 to rotate around the connecting shaft 33, and the second part 313 abuts against the abutting section 353 and compresses the elastic member 35; after the user releases the force on the button 51, the compressed torsion spring relies on its own elastic force to push the buckle member 31 in the reverse direction, that is, provides an upward force for the second part 313, and drives the first part 311 to rotate in the direction close to the inside of the housing 10, so that the buckle member 31 returns to the initial position, and the initial position is the position of the buckle member 31 when the button 51 does not bear force.

[0078] Please continue to refer to Figure 2 , in some embodiments, the second wall 105 of the housing 10 is provided with a through hole 1051. The button assembly 50 includes a button 51 and a mounting seat 53. The button 51 is installed in the through hole 1051, and the part to be locked 511 is arranged on the first side 5101 of the button 51 facing the inside of the housing 10. The mounting seat 53 is connected to the first side 5101 of the button 51 and forms an installation cavity 55 together with the button 51. The second part 313 and the abutting section 353 are located in the installation cavity 55.

[0079] Specifically, the perforation 1051 is a spatial structure for other components to extend into. The perforation 1051 penetrates through the second wall 105, which can reduce the material used for the second wall 105, thereby reducing the weight of the housing 10. The cross-sectional shape of the perforation 1051 includes, but is not limited to, circular, oval, triangular, quadrilateral, racetrack-shaped, or other polygonal shapes, etc. In this application, the perforation 1051 is racetrack-shaped. Preferably, the cross-sectional shape of the perforation 1051 is adapted to the outer contour shape of the button 51 to reduce the gap between the perforation 1051 and the button 51 and prevent dust from entering the interior of the housing 10. In this application, after the button 51 extends into the perforation 1051, it is connected to the mounting base 53. The to-be-locked portion 511 is provided on the first side 5101 of the button 51 and is opposite to the guiding member 11 in the first direction Z. The to-be-locked portion 511 can move along with the button 51 in the first direction Z. The mounting base 53 and the button 51 together form a mounting cavity 55, which can save materials while providing a receiving space. The mounting base 53, as a fixing structure, can provide a stable support for the button 51 to prevent the button 51 from shifting or loosening during use, where the second part 313 and the abutting section 353 are located in the mounting cavity 55.

[0080] Please refer to Figure 2 , in some embodiments, a clamping arm 513 is further provided on the first side 5101 of the button 51. A clamping portion 5131 is provided on the clamping arm 513, and a mating portion 531 is provided on the mounting base 53. The clamping portion 5131 is in mating connection with the mating portion 531 to detachably connect the mounting base 53 and the button 51.

[0081] Specifically, the mounting base 53 and the button 51 are snap-connected. In the embodiment where the clamping portion 5131 is a snap, the mating portion 531 is a snap hole that mates with the snap; in the embodiment where the clamping portion 5131 is a snap hole, the mating portion 531 is a snap that mates with the snap. In this application, the clamping portion 5131 is a snap, and the mating portion 531 is a snap hole. The cooperation between the clamping portion 5131 and the mating portion 531 can make the connection between the button 51 and the second part 313 stable, so that the button 51 can drive the second part 313 to rotate in the first direction Z.

[0082] Please continue to refer to Figure 2 , in some embodiments, an anti-slip protrusion 515 is provided on the second side 5102 of the button 51 facing away from the interior of the housing 10.

[0083] Specifically, the second side 5102 of the button 51 is the side located in the external environment. The user applies a force to the second side 5102 to retract the button 51 into the interior of the housing 10. On the one hand, the anti-slip protrusions 515 can serve as a pressing mark to distinguish the second side 5102 from the outer side surface 75 of the housing 10, reminding the user that this place can be pressed. On the other hand, the anti-slip protrusions 515 can also increase the friction between the button 51 and the human hand, improving the user's pressing effect. The anti-slip protrusions 515 can be one or more. The projection of the anti-slip protrusions 515 on the plane where the second side 5102 is located can be circular, elliptical, triangular, quadrilateral or other polygons. In this application, the projection of the anti-slip protrusions 515 on the plane where the second side 5102 is located is a runway shape. Multiple runway-shaped anti-slip protrusions 515 are arranged at intervals in the third direction Y. The runway-shaped anti-slip protrusions 515 have no sharp corners, which can avoid scratching the user.

[0084] Please refer to Figure 2 and Figure 3 , in some embodiments, the first side 5101 of the button 51 is further provided with a first connecting portion 517, and the second portion 313 is provided with a second connecting portion 3131. The first connecting portion 517 cooperates with the second connecting portion 3131 to connect the button 51 to the second portion 313.

[0085] Specifically, the first connecting portion 517 can be one or more, and the second connecting portion 3131 can be one or more. Preferably, the number of the first connecting portion 517 and the second connecting portion 3131 is the same. In this application, the first connecting portion 517 is two, and the second connecting portion 3131 is also two. The two first connecting portions 517 cooperate with the two second connecting portions 3131 respectively to form two connecting groups. If one of the connecting groups is damaged, there is still one connecting group that can play a connecting role, thereby providing a redundant design. In one example, the first connecting portion 517 and the second connecting portion 3131 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or screw connection, etc. In another example, the first connecting portion 517 and the second connecting portion 3131 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc. In this application, the first connecting portion 517 is a protrusion extending along the first direction Z of the button 51, and the second connecting portion 3131 is a through hole matching the protrusion. After the button 51 is connected to the mounting seat 53, the first connecting portion 517 passes through the second connecting portion 3131, thereby limiting the second portion 313 and preventing the second portion 313 from shifting during rotation in the Z direction.

[0086] Please refer to Figure 2, in some embodiments, a limiting protrusion 519 is provided on at least one side wall 5103 of the button 51. The limiting protrusion 519 is located inside the housing 10 and abuts against the inner wall 101 of the housing 10.

[0087] Specifically, the limiting protrusion 519 is used to prevent the button 51 from falling off from the inside of the housing 10. The limiting protrusion 519 can be one or more, and the number of limiting protrusions 519 on different side walls 5103 can be different. In the present application, two limiting protrusions 519 are respectively provided on two side walls 5103 in the second direction X of the button 51. In the present application, the limiting protrusion 519 is a protrusion formed from the side wall 5103 where the limiting protrusion 519 is located in a direction away from the side wall 5103, that is, the limiting protrusion 519 and the button 51 are of an integral structure, thereby enhancing the bonding strength between the limiting protrusion 519 and the button 51. In other embodiments, the limiting protrusion 519 and the button 51 can be of a split structure.

[0088] In the projection in the first direction Z, the button 51 is located outside the projection of the through hole 1051, and at least part of the limiting protrusion 519 is located outside the projection of the through hole 1051. Thus, when the button 51 is subjected to a force opposite to the force in the first direction Z, the limiting protrusion 519 can abut against the inner wall 101 of the housing 10 to prevent the button 51 from falling off from the through hole 1051. Two limiting protrusions 519 are respectively provided on two side walls 5103 of the button 51, which can provide uniform support for the button 51.

[0089] In some embodiments, a support portion 533 is provided on the side of the mounting seat 53 facing the button 51, and the support portion 533 is used to support the first portion 311.

[0090] Specifically, the support portion 533 is provided at one end of the mounting seat 53 close to the elastic member 35 and protrudes and extends in a direction close to the button 51. In the case where the button assembly 50 is released after being subjected to a force in the first direction Z, the first portion 311 can rotate in the direction of the inside of the housing 10. At this time, the support portion 533 can support the first portion 311, that is, the support portion 533 can provide a support point for the first portion 311, so that the rotation of the buckle member 31 is more stable.

[0091] Please refer to Figure 11 , the present application further provides an energy storage device 10000. The energy storage device 10000 includes the connector 1000, the energy storage battery 3000, and the circuit board 5000 according to any one of the above embodiments. The connector 1000 is used to electrically connect the energy storage battery 3000 and the circuit board 5000.

[0092] Among them, the energy storage battery 3000 is a device for storing electric energy and supplying power to other components. The energy storage device 10000 is a device including a plurality of electrically connected energy storage batteries 3000. The energy storage device 10000 can be an outdoor power supply, a home energy storage power supply, a photovoltaic system, etc.

[0093] In the first connection structure 100 of the energy storage device 10000 of the present application, by providing the guiding member 11 and the sliding member 70, when the button assembly 50 does not need to move along the first direction Z, the sliding member 70 moves relative to the guiding member 11 along the second direction X to a position where the locking portion 71 abuts against the portion to be locked 511, restricting the movement of the button assembly 50 along the first direction Z, thereby avoiding accidental touch of the button assembly 50 when it does not need to be pressed, resulting in the button assembly 50 driving the buckle assembly 30 to rotate. Thus, the connection stability between the buckle assembly 30 and the components connected thereto can be ensured; when the button assembly 50 needs to move along the first direction Z, the sliding member 70 moves relative to the guiding member 11 along the second direction X to a position where the locking portion 71 disengages from the portion to be locked 511, ensuring that the button assembly 50 can move along the first direction Z.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
