Connector assembly

Abstract

The application relates to a connector assembly, comprising a first connector and a second connector. The first connector further comprises a buckle, an elastic member and a locking member. The buckle rotates relative to the first housing along an axis of rotation. The buckle has a free position, a first operating position and a second operating position relative to the first housing. The first operating position is between the free position and the second operating position. The elastic member is arranged between the buckle and the first housing, and the elastic member generates an elastic force on the buckle. The elastic force is used to reset the buckle to the free position. When the first power terminal and the second power terminal are separated, the load current has already stopped, so that arc discharge does not occur when the first power terminal and the second power terminal are separated, thereby avoiding melting or vaporization of the power terminal and preventing carbonization and decomposition of the insulating material around the power terminal.

Description

Technical Field

[0001] This application relates to the field of electrical connection device technology, and in particular to a connector assembly. Background Technology

[0002] Connector assemblies are devices used to enable electrical connections between different devices. The application of connector assemblies improves the efficiency of electrical connections between different devices and is currently widely used in the automotive, communications, consumer electronics, data processing, and industrial machinery industries.

[0003] A connector assembly typically includes two connectors that enable electrical connection. One connector serves as a socket, fixed to a device, panel, or circuit board. The other connector serves as a plug, connecting to one end of a cable.

[0004] The connector has internal power terminals. When the two connectors are mated, they form a locking engagement through a locking structure, creating a stable conductive contact between the power terminals. At this point, one connector can transfer load current to the other.

[0005] However, when load current is being transferred between the two connectors, the two connectors are in a free-separating state when the locking mechanism unlocks, and a large current still flows through the power terminals of the two connectors before separation. At the instant the power terminals separate, an arc discharge occurs between them due to the inductance in the circuit. This arc discharge may cause the power terminals to melt or vaporize, resulting in pits or burrs on the surface, potentially leading to poor contact during subsequent use. Furthermore, the arc discharge may also cause the insulation material around the power terminals to carbonize and decompose, resulting in a decrease in insulation effectiveness. Summary of the Invention

[0006] Based on this, the present invention provides a connector assembly that can solve or at least alleviate the above-mentioned technical problems.

[0007] This invention provides a connector assembly, comprising:

[0008] The first connector includes a first housing, a snap-fit ​​member rotatably mounted on the first housing, and a locking member slidably connected to the first housing; the snap-fit ​​member has a free position, a first operating position, and a second operating position relative to the first housing; the first operating position is located between the free position and the second operating position; the locking member has a first position and a second position relative to the first housing; one of the snap-fit ​​member and the locking member is provided with a first stop surface, and the other is provided with a second stop surface and a recess;

[0009] The second connector includes a second housing and a limiting portion connected to the second housing; the limiting portion is provided with a third stop surface and a fourth stop surface; the third stop surface is disposed downstream of the fourth stop surface along the insertion direction; the orientations of the third stop surface and the fourth stop surface correspond to the insertion direction respectively; the third stop surface has a first free edge, and the fourth stop surface has a second free edge; along the radial direction of the second housing, the first free edge and the second free edge are spaced apart by a first preset distance;

[0010] The first housing has a locked position and an unlocked transition position relative to the second housing. When the first housing is in the locked position, the latch is in the free position, and the locking member is in the first position, the latch and the third stop surface form a stop engagement, and the first stop surface and the second stop surface are opposite to each other and spaced apart by a second preset distance. When the first housing is in the unlocked transition position, the latch is in the first operating position, and the locking member is in the first position, the latch and the fourth stop surface form a stop engagement, and the first stop surface and the second stop surface form a stop engagement. When the latch is in the second operating position and the locking member is in the second position, the first stop surface is accommodated in a recess, and the latch avoids the fourth stop surface.

[0011] In the aforementioned connector assembly, when the first housing is in the unlocked transition position relative to the second housing, the locking member can be switched from a first position to a second position by sliding the locking member relative to the first housing. When the locking member is in the second position, the recess aligns with the first stop surface, providing further room for movement for the latching member in the first operating position. When the latching member continues to be operated, rotating a certain distance from the first operating position, the structure around the first stop surface is accommodated within the recess, allowing the latching member to reach the second operating position. When the latching member is in the second operating position, it bypasses the fourth stop surface, and the second connector can continue to move relative to the second housing in the pull-out direction until the first power terminal and the second power terminal are completely separated. Since the load current stops when the first power terminal and the second power terminal separate, no arc discharge occurs during separation, thus preventing melting or vaporization of the power terminals and preventing carbonization and decomposition of the insulating material around the power terminals.

[0012] In one embodiment, the second stop surface and the recess are disposed on the locking member; the second stop surface is disposed downstream of the recess along the insertion direction; the first connector has a pre-insertion position relative to the second connector; in the pre-insertion position, the locking member in the second position is abutted against the second connector along the insertion direction.

[0013] In one embodiment, at the pre-insertion position, the locking member is abutted against the second housing in the insertion direction.

[0014] In one embodiment, the locking member includes a mounting portion and a contact portion connected to the mounting portion; the mounting portion is movably disposed between the snap fastener and the first housing; the second stop surface and the recess are disposed on the mounting portion; the recess, the second stop surface and the contact portion are sequentially distributed along the insertion direction; at the pre-insertion position, the contact portion and the second connector are abutted against each other along the insertion direction.

[0015] In one embodiment, the locking member further includes a first force-applying portion connected to the mounting portion; the first force-applying portion is at least partially disposed outside the first housing; along the insertion direction, the outer surface of the first force-applying portion is inclined in a direction away from the first housing.

[0016] In one embodiment, the second connector further includes a second power terminal positioned within the second housing; the distance between the fourth stop surface and the second power terminal is less than the distance between the third stop surface and the second power terminal along the radial direction of the second housing.

[0017] In one embodiment, the limiting portion is provided with an inclined surface; the fourth stop surface is disposed downstream of the inclined surface along the insertion direction; along the insertion direction, the inclined surface is inclined toward the direction close to the second power terminal.

[0018] In one embodiment, the fastener includes a main fastening portion and a second force-applying portion connected to the main fastening portion; the main fastening portion is rotatably disposed relative to the first housing along the rotation axis; the second force-applying portion is disposed downstream of the rotation axis along the insertion direction.

[0019] In one embodiment, the second housing is provided with a guide groove; the guide groove is for the buckle to pass through; the limiting part is disposed in the guide groove, and the limiting part protrudes relative to the inner wall surface of the guide groove.

[0020] In one embodiment, the fastener includes a main fastener portion and a side block portion; the main fastener portion is rotatably disposed relative to the first housing along a rotation axis; the first stop surface is disposed on the side block portion; and the main fastener portion is connected to the side block portion on at least one side in a direction parallel to the rotation axis.

For example, they can refer to fixed connections, detachable connections, integral connections, mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0044] Combination Figure 1 and Figure 2 As shown, this application provides a connector assembly 300, including a first connector 100 and a second connector 200.

[0045] In some embodiments, the first connector 100 is used for electrical connection to one device, and the second connector 200 is used for electrical connection to another different device. Once the first connector 100 and the second connector 200 are mechanically and electrically mated, electrical energy or electronic signals can be transmitted between the two devices. In other embodiments, the first connector 100 and the second connector 200 can also be used within the same device to transmit electrical energy and electronic signals between two different modules of that device.

[0046] In some embodiments, the first connector 100 and the second connector 200 are mechanically locked in their relative positions by a snap-fit ​​connection. In some embodiments, after the first connector 100 and the second connector 200 are snap-fitted, their ports remain in a plugged-in state.

[0047] In some embodiments, one of the first connector 100 and the second connector 200 may serve as a socket and be fixed to a device, panel, or circuit board. In one embodiment, one of the first connector 100 and the second connector 200 may be fixed to a cabinet panel of the device. The other of the first connector 100 and the second connector 200 serves as a plug and is connected to another device via an electrical cable.

[0048] In some implementations, combined Figure 7 and Figure 8 As shown, the first connector 100 includes a first housing 11, a first signal terminal 12, and a first power terminal 13. The first signal terminal 12 and the first power terminal 13 are respectively positioned and housed within the first housing 11. Exemplarily, the first connector 100 further includes a first insulating member 14 housed within the first housing 11. The first signal terminal 12 and the first power terminal 13 are respectively inserted into the first insulating member 14.

[0049] In some implementations, combined Figure 6 and Figure 7 As shown, the second connector 200 includes a second housing 21, a second signal terminal 22, and a second power terminal 23. The second signal terminal 22 and the second power terminal 23 are respectively positioned and housed within the second housing 21. Exemplarily, the second connector 200 also includes a second insulating member 24 housed within the second housing 21. The second signal terminal 22 and the second power terminal 23 are respectively inserted into the second insulating member 24.

[0050] Specifically, in combination Figure 1 and Figure 2 As shown, the first connector 100 and the second connector 200 correspond to a predetermined insertion direction F1. When the position of the second connector 200 is relatively fixed, a portion of the first connector 100 can be accommodated into the second connector 200 along the insertion direction F1. Exemplarily, the first housing 11, the first signal terminal 12, or the first power terminal 13 can be accommodated into the second connector 200 along the insertion direction F1. The first connector 100 and the second connector 200 also correspond to a predetermined withdrawal direction F2. When the position of the second connector 200 is relatively fixed, the first connector 100 can be separated from the second connector 200 along the withdrawal direction F2. Understandably, the withdrawal direction F2 is opposite to the insertion direction F1.

[0051] Specifically, in combination Figure 6As shown, the second connector 200 also includes a limiting portion 25 connected to the second housing 21. The limiting portion 25 has a third stop surface 251 and a fourth stop surface 252. The third stop surface 251 is disposed downstream of the fourth stop surface 252 along the insertion direction F1, and the orientations of the third stop surface 251 and the fourth stop surface 252 correspond to the insertion direction F1, respectively. The third stop surface 251 has a first free edge 253, and the fourth stop surface 252 has a second free edge 254. Along the radial direction of the second housing 21, the first free edge 253 and the second free edge 254 are spaced apart by a first preset distance.

[0052] For example, the orientation of the third stop surface 251 and the orientation of the fourth stop surface 252 are approximately in the same direction as the insertion direction F1. For example, the orientation of the third stop surface 251 or the orientation of the fourth stop surface 252 may have a certain angle relative to the insertion direction F1 to prevent the latching member 15 from loosening from the third stop surface 251 or the fourth stop surface 252.

[0053] Specifically, in combination Figure 7 and Figure 10a As shown, the first housing 11 has a locked position and an unlocked transition position relative to the second housing 21.

[0054] Specifically, in combination Figures 3 to 5 As shown, the first connector 100 further includes: a snap-fit ​​member 15, an elastic member 16, and a locking member 17. The snap-fit ​​member 15 is rotatable relative to the first housing 11 along its rotation axis. The snap-fit ​​member 15 has a free position, a first operating position, and a second operating position relative to the first housing 11. The first operating position is located between the free position and the second operating position. The elastic member 16 is disposed between the snap-fit ​​member 15 and the first housing 11, and the elastic member 16 generates a spring force on the snap-fit ​​member 15. The spring force is used to reset the snap-fit ​​member 15 to the free position. The locking member 17 is slidably connected to the first housing 11, and the locking member 17 has a first position and a second position relative to the first housing 11. One of the snap-fit ​​member 15 and the locking member 17 has a first stop surface 151, and the other has a second stop surface 171 and a recess 172. When the latching member 15 is in the free position and the locking member 17 is in the first position, the first stop surface 151 and the second stop surface 171 are opposite to each other and spaced apart by a second preset distance. When the latching member 15 is in the first operating position and the locking member 17 is in the first position, a stop engagement is formed between the first stop surface 151 and the second stop surface 171. When the latching member 15 is in the first operating position and the locking member 17 is in the second position, the first stop surface 151 is opposite to the recess 172.

[0055] Specifically, when the first housing 11 is in the locked position, the latching member 15 is in the free position, and the locking member 17 is in the first position, a stop engagement is formed between the latching member 15 and the third stop surface 251, and the first stop surface 151 and the second stop surface 171 are opposite each other and spaced apart by a second preset distance. When the first housing 11 is in the unlocked transition position, the latching member 15 is in the first operating position, and the locking member 17 is in the first position, a stop engagement is formed between the latching member 15 and the fourth stop surface 252, and the first stop surface 151 and the second stop surface 171 are also in a stop engagement. When the latching member 15 is in the second operating position and the locking member 17 is in the second position, the first stop surface 151 is accommodated in the recess 172, and the latching member 15 avoids the fourth stop surface 252.

[0056] The connector of this application, combined with Figure 7 and Figure 8 As shown, when the first housing 11 is in the locked position relative to the second housing 21, a nested fit is formed between the first housing 11 and the second housing 21, a conductive contact is formed between the first signal terminal 12 and the second signal terminal 22, a conductive contact is formed between the first power terminal 13 and the second power terminal 23, and the first connector 100 and the second connector 200 are in a fully mated state. Specifically, load current can be transmitted between the first power terminal 13 and the second power terminal 23.

[0057] Combination Figure 7 and Figure 8 As shown, when the first housing 11 is in the locked position relative to the second housing 21 and the locking member 17 is in the first position, when the latching member 15 is in the free position due to elastic reset, a stop engagement is formed between the latching member 15 and the third stop surface 251. The third stop surface 251 inhibits the latching member 15 from moving relative to the second connector 200 in the pull-out direction F2, keeping the first connector 100 and the second connector 200 in a fully mated state, thereby ensuring the stable transmission of signals and load current. At the same time, the first stop surface 151 and the second stop surface 171 are opposite each other and spaced apart by a second preset distance, allowing the latching member 15 to rotate from the free position to the first operating position.

[0058] Combination Figure 9a and Figure 9b As shown, when the latching member 15 is subjected to a predetermined operation and rotates a certain distance from its free position, the first stop surface 151 abuts against the second stop surface 171, causing the latching member 15 to stop in the first operating position. When the latching member 15 is in the first operating position, the latching member 15 avoids the third stop surface 251, and the first connector 100 can then move relative to the second housing 21 in the pull-out direction F2 until the latching member 15 forms a stop engagement with the fourth stop surface 252, causing the first housing 11 to stop relative to the second housing 21 in the unlocked transition position.

[0059] Combination Figure 10a and Figure 10b As shown, when the first housing 11 is in the unlocked transition position relative to the second housing 21, the first power terminal 13 and the second power terminal 23 maintain conductive contact. Electrical isolation is formed between the first signal terminal 12 and the second signal terminal 22. This separation provides feedback to the external control module, which then uses corresponding switching devices to stop the load current based on this feedback.

[0060] Combination Figure 11a and Figure 11b As shown, when the first housing 11 is in the unlocked transition position relative to the second housing 21, the locking member 17 can be switched from the first position to the second position by sliding it relative to the first housing 11. When the locking member 17 is in the second position, the recess 172 faces the first stop surface 151, providing further room for movement for the latching member 15 in the first operating position. Figure 12a and Figure 12b As shown, when the latching member 15 continues to be subjected to a predetermined operation, after rotating a certain distance from the first operating position, the structure around the first stop surface 151 is accommodated in the recess 172, allowing the latching member 15 to reach the second operating position. When the latching member 15 is in the second operating position, the latching member 15 avoids the fourth stop surface 252, and the second connector 200 can continue to move relative to the second housing 21 in the pull-out direction F2 until the first power terminal 13 and the second power terminal 23 are completely separated. Since the load current has stopped when the first power terminal 13 and the second power terminal 23 are separated, no arc discharge will occur when the first power terminal 13 and the second power terminal 23 are separated, thereby avoiding melting or vaporization of the power terminals and preventing carbonization and decomposition of the insulating material around the power terminals.

[0061] Understandably, the engagement between the fourth stop surface 252 and the latching member 15 in the first operating position creates a pause phase during the separation process of the first connector 100 and the second connector 200. This pause phase provides the necessary response time for the control module and switching devices, allowing them to stop the load current in time before the first power terminal 13 and the second power terminal 23 are completely separated, thus avoiding the occurrence of arc discharge.

[0062] Understandably, when the first housing 11 is in the unlocked transition position relative to the second housing 21, and the locking member 17 is in the first position, the operator needs to move the locking member 17 to the second position before the latching member 15, which is in the first operating position, can be further operated to the second operating position. Therefore, before moving the locking member 17 to the second position, the latching member 15 cannot be bypassed by operating it alone, so as to avoid the first connector 100 being able to separate from the second connector 200 in a short time due to the operation of the latching member 15 alone, and to ensure that there is a pause during the separation process between the second connector 200 and the first connector 100.

[0063] In some implementations, combined Figure 13 As shown, a second stop surface 171 and a recess 172 are disposed on the locking member 17. The second stop surface 171 is disposed downstream of the recess 172 along the insertion direction F1. The first connector 100 has a pre-insertion position relative to the second connector 200. In the pre-insertion position, the locking member 17 in the second position abuts against the second connector 200 along the insertion direction F1. Understandably, since the second stop surface 171 and the recess 172 are disposed on the locking member 17, and the second stop surface 171 is disposed downstream of the recess 172 along the insertion direction F1, the sliding direction of the locking member 17 from the second position to the first position is approximately in the same direction as the pull-out direction F2. During the mating process between the first connector 100 and the second connector 200, the first connector 100 approaches the second connector 200 along the insertion direction F1. When the first connector 100 reaches the pre-interlocking position relative to the second connector 200, the locking member 17 in the second position abuts against the second connector 200 along the insertion direction F1. Under the pushing action of the second connector 200, the locking member 17 slides relative to the first housing 11 along the pull-out direction F2, reaching the first position. Therefore, during the docking process between the first connector 100 and the second connector 200, the locking member 17 can be reset to the first position by the pushing action of the second connector 200, avoiding the need for the user to manually reset the locking member 17 to the first position, thus simplifying the operation of the locking member 17.

[0064] In other embodiments, the second stop surface 171 and the recess 172 may be provided on the fastener 15, with the recess 172 located downstream of the second stop surface 171 along the insertion direction F1.

[0065] In some embodiments, in the pre-insertion position, the locking member 17 and the second housing 21 are abutted against each other along the insertion direction F1. Exemplarily, the second housing 21 has an insertion end and a wire harness end facing each other along the insertion direction F1. In the fully mated state, the insertion end of the second housing 21 forms a nested fit with one end of the first housing 11. In the pre-insertion position, the locking member 17 in the second position is abutted against the insertion end of the second housing 21 along the insertion direction F1.

[0066] In some implementations, combined Figure 3 and Figure 7 As shown, the first housing 11 includes a first main housing 111 and a boss portion 112 connected to the first main housing 111. The boss portion 112 protrudes from the outer periphery of the first main housing 111. The boss portion 112 has an opening 113. A latching member 15 and a locking member 17 are respectively movably disposed through the opening 113. Understandably, a portion of the latching member 15 is housed within the boss portion 112, and another portion is exposed through the opening 113 of the boss portion 112, so that the user can operate the exposed portion of the latching member 15. A portion of the locking member 17 is housed within the boss portion 112, and another portion is exposed through the opening 113 of the boss portion 112, so that the user can operate the exposed portion of the locking member 17.

[0067] In some implementations, combined Figure 7 As shown, the latching member 15 includes a main latching portion 152 and a latching portion 153 connected to the main latching portion 152. The main latching portion 152 is rotatably connected to the first housing 11. The latching portion 153 is disposed downstream of the rotation axis along the insertion direction F1. An elastic member 16 abuts between the main latching portion 152 and the first housing 11. Understandably, by pressing the latching member 15 inward toward the first housing 11, the elastic member 16 can be compressed, causing the latching portion 153 to swing inward toward the first housing 11. For the free position, the first operating position, and the second operating position, the distance between the latching portion 153 and the first power terminal 13 decreases sequentially. Correspondingly, along the radial direction of the second housing 21, the distance between the fourth stop surface 252 and the second power terminal 23 is less than the distance between the third stop surface 251 and the second power terminal 23, that is, the second free edge 254 is closer to the second power terminal 23 relative to the first free edge 253. For example, the elastic element 16 abuts between the main buckle portion 152 and the first main housing 111. Understandably, the main buckle portion 152 is rotatably disposed relative to the first housing 11 along the axis of rotation.

[0068] For example, combined Figure 7As shown, in the free position, the engaging portion 153 forms a stop engagement with the third stop surface 251. When the latching member 15 rotates from the free position to the first operating position, the engaging portion 153 rotates in the direction close to the first power terminal 13 and avoids the third stop surface 251. Subsequently, since the third stop surface 251 is disposed downstream of the fourth stop surface 252 along the insertion direction F1, the engaging portion 153 is now spaced apart from the fourth stop surface 252 along the insertion direction F1, allowing the first connector 100 to move relative to the second connector 200 along the withdrawal direction F2. When the engaging portion 153 abuts against the fourth stop surface 252, the first housing 11 is in an unlocked transition position relative to the second housing 21.

[0069] When the first housing 11 is in the unlocked transition position and the locking member 17 is in the second position, when the latching member 15 rotates from the first operating position to the second operating position, the latching part 153 rotates in a direction that is further closer to the first power terminal 13 and avoids the fourth stop surface 252.

[0070] In some implementations, combined Figure 3 and Figure 7 As shown, the first connector 100 also includes a shaft 18 parallel to the rotation axis, which is inserted into the latching member 15 and the first housing 11. At least one of the latching member 15 and the first housing 11 is rotatably disposed relative to the shaft 18. Exemplarily, the shaft 18 is inserted into the main latch portion 152 and the boss portion 112. Understandably, the position of the shaft 18 coincides with the rotation axis.

[0071] In some implementations, combined Figure 6 As shown, the limiting portion 25 is provided with an inclined surface 255. A fourth stop surface 252 is disposed downstream of the inclined surface 255 along the insertion direction F1. Along the insertion direction F1, the inclined surface 255 is inclined towards the direction of the second power terminal 23. Understandably, during the mating process between the first connector 100 and the second connector 200, when the latching member 15 moves along the insertion direction F1 to contact the limiting portion 25, the latching member 15 makes contact with the inclined surface 255 of the limiting portion 25. The inclination angle of the inclined surface 255 causes the inclined surface 255 to form a component force on the latching member 15, which can guide the latching member 15 in its free position to rotate towards the second operating position, thereby enabling the latching member 15 to automatically avoid the limiting portion 25. Exemplarily, during the mating process between the first connector 100 and the second connector 200, the inclined surface 255 is used to form a sliding contact with the fastening portion 153.

[0072] In some implementations, combined Figure 6As shown, the limiting part 25 is also provided with a transition surface 256, which is formed between the first free edge 253 and the fourth stop surface 252 along the insertion direction F1. Understandably, when the first housing 11 is in the unlocked transition position and the latching member 15 is in the first operating position, the latching member 15 is held in the first operating position by the abutment of the transition surface 256, thereby preventing the latching member 15 from springing back to the free position. After sliding the locking member 17 to the second position, the user only needs to press the latching member 15 slightly to make it avoid the fourth stop surface 252.

[0073] In some implementations, combined Figure 6 As shown, the second housing 21 is provided with a guide groove 211. The guide groove 211 is used for the fastener 15 to pass through. A limiting part 25 is disposed in the guide groove 211, and the limiting part 25 protrudes relative to the inner wall surface of the guide groove 211. Understandably, the fastener 15 passing through the guide groove 211 can limit the circumferential relative angle between the first connector 100 and the second connector 200. Since the limiting part 25 is disposed in the guide groove 211, under the guiding action of the guide groove 211, the fastener 15 can accurately cooperate with the third stop surface 251 or the fourth stop surface 252.

[0074] In some implementations, combined Figure 4a and Figure 7 As shown, the latching member 15 has a slot 156. When the first housing 11 is in the locked position relative to the second housing 21, the limiting part 25 is fully inserted into the slot 156 when the locking member 17 is in the first position. When the first housing 11 is in the unlocked transition position relative to the second housing 21, the limiting part 25 is partially inserted into the slot 156 when the locking member 17 is in the first operating position.

[0075] For example, the slot 156 is provided in the fastening part 153. For example, the slot 156 is a through slot structure. For example, the slot 156 is a recessed structure.

[0076] In some implementations, combined Figure 4b and Figure 7 As shown, the latching member 15 also includes a second force-applying part 154 connected to the main latching part 152. The second force-applying part 154 is disposed downstream of the rotation axis along the insertion direction F1. Understandably, the user can press the latching member 15 through the second force-applying part 154 to rotate the latching member 15 from the free position to the first operating position, or to slide the latching member 15 from the first operating position to the second operating position.

[0077] In some implementations, combined Figure 4a and Figure 4bAs shown, the latching member 15 also includes a side block portion 155. A first stop surface 151 is provided on the side block portion 155. The main latching portion 152 is connected to the side block portion 155 on at least one side in a direction parallel to the rotation axis. Understandably, the side block portion 155 protrudes relative to the side of the main latching portion 152. When the main latching portion 152 rotates relative to the first housing 11, the side block portion 155 rotates accordingly.

[0078] For example, the first stop surface 151 is generally perpendicular to the side of the main buckle portion 152.

[0079] Optionally, the first stop surface 151 or the second stop surface 171 is not limited to being disposed on one side of the fastener 15, but may also be disposed in the middle of the fastener 15 or other positions.

[0080] In some implementations, combined Figures 4a to 5 As shown, side blocks 155 are connected to both sides of the main buckle 152. The locking member 17 has a second stop surface 171 and a recess 172 formed on both sides of the main buckle 152. Understandably, when the locking member 17 is in the first position, when the latching member 15 rotates to the first operating position, the side blocks 155 on both sides of the main buckle 152 respectively engage with the locking member 17, thereby reliably preventing the latching member 15 from rotating to the second operating position.

[0081] For example, the locking member 17 abuts between the side block portion 155 and the first housing 11.

[0082] In some implementations, combined Figure 5 and Figure 8 As shown, the locking member 17 includes a mounting portion 174 and a first force-applying portion 173 connected to the mounting portion 174. Understandably, the user can exert a pushing force on the locking member 17 through the first force-applying portion 173, causing the locking member 17 to slide from a first position to a second position, or to slide the locking member 17 from a second position to a first position.

[0083] In some embodiments, the first force-applying part 173 is disposed adjacent to the second force-applying part 154 along the insertion direction F1.

[0084] For example, the second force-applying part 154 and the first force-applying part 173 are provided on the outside of the opening 113 of the boss part 112 to facilitate user operation. For example, along a direction parallel to the rotation axis, the width of the second force-applying part 154 or the first force-applying part 173 is greater than the width of the opening 113 of the boss part 112, thereby increasing the force-receiving area of ​​the second force-applying part 154 or the first force-applying part 173.

[0085] For example, combined Figure 2As shown, the second force-applying part 154 is disposed downstream of the first force-applying part 173 along the insertion direction F1. The locking member 17, which is in the first position, slides to the second position along the insertion direction F1.

[0086] In some implementations, combined Figure 7 As shown, the first force-applying part 173 is at least partially disposed outside the first housing 11. Along the insertion direction F1, the outer surface of the first force-applying part 173 is inclined in a direction opposite to the first housing 11. Understandably, the sliding direction from the first position to the second position is approximately in the same direction as the insertion direction F1. Along the insertion direction F1, since the height of the outer surface of the first force-applying part 173 relative to the first housing 11 gradually increases, it is beneficial for the finger to generate a pressing force on the first force-applying part 173. This pressing force is approximately in the same direction as the insertion direction F1, generating a pushing effect on the locking member 17, which helps to reduce the operating force required for the locking member 17.

[0087] For example, combined Figure 5 and Figure 7 As shown, along the insertion direction F1, the outer surface of the first force-applying part 173 has a concave-convex transition, which helps to increase the friction between the finger and the first force-applying part 173.

[0088] In some implementations, combined Figure 7 and Figure 8 As shown, a portion of the mounting portion 174 of the locking member 17 is disposed between the main latch portion 152 and the first housing 11. Understandably, since the main latch portion 152 of the latching member 15 is rotatably connected to the first housing 11, when the rotation range of the main latch portion 152 is limited to a certain extent, the main latch portion 152 can cooperate with the first housing 11 to limit the range of motion of the mounting portion 174, thereby preventing the locking member 17 from disengaging from the first housing 11.

[0089] In some implementations, combined Figure 8 As shown, the locking member 17 also includes a connecting portion 175. The connecting portion 175 is movably inserted through the opening 113 of the boss portion 112. When the locking member 17 moves to the second position, the connecting portion 175 and the latching member 15 form a stop engagement to prevent the locking member 17 from moving too much and to prevent the first stop surface 151 from failing to align with the recess 172.

[0090] For example, combined Figure 5 As shown, the connecting portion 175 connects the mounting portion 174 and the first force-applying portion 173. When the locking member 17 slides to the second position along the insertion direction F1, the connecting portion 175 abuts against the side block portion 155, thereby restricting further movement of the locking member 17 along the insertion direction F1. Exemplarily, when the locking member 17 is in the second position, the connecting portion 175 is arranged approximately parallel to the side block portion 155, which facilitates guiding the side block portion 155 into the recess 172.

[0091] In some implementations, combined Figure 4b and Figure 11b As shown, one of the latching member 15 and the locking member 17 has a slot 157, and the other has a protrusion 176. The extending directions of the slot 157 and the protrusion 176 correspond to the axis of rotation, respectively. When the locking member 17 is in the second position, the protrusion 176 is at least partially received in the slot 157. Understandably, after the locking member 17 is slid to the second position, since the protrusion 176 is at least partially received in the slot 157, it helps to stably keep the locking member 17 in the second position, preventing spontaneous movement of the locking member 17 that would prevent the latching member 15 from rotating from the first operating position to the second operating position.

[0092] In some implementations, combined Figure 5 As shown, the locking member 17 also includes a contact portion 177 connected to the mounting portion 174. The mounting portion 174 is slidably disposed between the snap fastener 15 and the first housing 11. A second stop surface 171 and a recess 172 are disposed on the mounting portion 174. The recess 172, the second stop surface 171, and the contact portion 177 are sequentially distributed along the insertion direction F1. In the pre-insertion position, the contact portion 177 and the second connector 200 are abutted against each other along the insertion direction F1. Understandably, the contact portion 177 plays a transmission role between the mounting portion 174 and the second connector 200. The second connector 200 pushes the mounting portion 174 to move through the contact portion 177, causing the recess 172 to move away from the position opposite to the first stop surface 151, while the second stop surface 171 moves to the position opposite to the first stop surface 151.

[0093] For example, a portion of the mounting portion 174 is disposed between the main latch portion 152 and the first housing 11. The contact portion 177 is accommodated within the boss portion 112, and the contact portion 177 is at least partially disposed on the outer peripheral side of the edge of the opening 113.

[0094] For example, the contact portions 177 are arranged in pairs, with the two contact portions 177 respectively disposed on both sides of the fastener 15.

[0095] In other embodiments, the second stop surface 171 and the recess 172 may be provided on the side block portion 155, and the first stop surface 151 may be provided on the locking member 17.

[0096] In other embodiments, the distance between the engaging portion 153 and the first power terminal 13 may increase sequentially for the free position, the first operating position, and the second operating position. Correspondingly, the distance between the third stop surface 251 and the second power terminal 23 is less than the distance between the fourth stop surface 252 and the second power terminal 23, that is, the first free edge 253 is closer to the second power terminal 23 than the second free edge 254.

[0097] The above embodiments are merely preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
