Description

Technical Field

[0001] This application relates to the field of electrical connection device technology, and in particular to a connector. 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 power terminals inside. When the two connectors are mated in place, one connector forms a locking engagement with the other connector through a snap-fit ​​component, and a stable conductive contact is formed between the power terminals of the two connectors. At this time, the snap-fit ​​component is in a free position.

[0005] When load current is being transmitted between two connectors, in order to prevent the two connectors from separating directly, conventional technology involves the latching component being operated to the unlocked position and the two connectors moving a predetermined distance in the pull-out direction. After this, the latching component is stopped again, allowing the control module to recognize the separation of the signal terminals and stop the load current using a switching device.

[0006] However, some users may not be clear about how to operate the latching component. They may release the latching component quickly after it has been moved to the unlocked position. This results in the latching component not being stopped a second time after the signal terminals are separated. The control module and switching devices do not receive the necessary response time, causing a large current to still flow through the power terminals of the two connectors when they are separated, resulting in arc discharge. Utility Model Content

[0007] Based on this, the present invention provides a connector that can solve or at least alleviate the above-mentioned technical problems.

[0008] This utility model provides a connector, comprising:

[0009] First shell;

[0010] A latching component is rotatably disposed relative to the first housing along a rotation axis; it 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.

[0011] An elastic element is used to generate a spring force on the snap-fit ​​component; the spring force is used to return the snap-fit ​​component to a free position; and

[0012] A locking member is movably connected to the first housing and has a first position and a second position relative to the first housing. One of the latching member and the locking member has a first stop surface, and the other has a second stop surface and a recess. When the latching member is in the free position and the locking member is in the first position, the first stop surface and the second stop surface are opposite to each other and spaced apart by a first preset distance. When the latching member is in the first operating position and the locking member is in the first position, the first stop surface and the second stop surface form a stop fit. When the latching member is in the first operating position and the locking member is in the second position, the first stop surface and the recess are opposite to each other.

[0013] In the aforementioned connector, with the locking member in the first position relative to the first housing, the user can only move the latching member from the free position to the first operating position. At this time, the first housing can only move relative to the second housing to the unlocked transition position. After the user moves the latching member from the free position to the first operating position and immediately releases it, the latching member cannot avoid the fourth stop surface. After the latching member is moved to the first operating position, the user needs to further switch the locking member from the first position to the second position before the latching member can rotate to the second operating position and avoid the fourth stop surface. The time period between the signal terminal separation point and the power terminal separation point includes the operation time for switching the locking member from the first position to the second position, thereby ensuring that the control module and switching devices receive the necessary response time, avoiding the occurrence of arc discharge when the first power terminal and the second power terminal are separated.

[0014] In one embodiment, the fastener includes a main fastening portion and a fastening portion connected to the main fastening portion; the main fastening portion is rotatably connected to the first housing; the fastening portion is disposed downstream of the rotation axis along the insertion direction; and the elastic element abuts between the main fastening portion and the first housing.

[0015] In one embodiment, the fastener further includes a first force-applying portion connected to the main fastener; the first force-applying portion is disposed downstream of the rotation axis along the insertion direction; the locking member has a second force-applying portion; the second force-applying portion is disposed adjacent to the first force-applying portion along the insertion direction.

[0016] In one embodiment, the second force-applying part is at least partially disposed outside the first housing; along the insertion direction, the outer surface of the second force-applying part is inclined in a direction away from the first housing.

[0017] In one embodiment, the locking member further includes a mounting portion connected to the second force-applying portion; a portion of the mounting portion is disposed between the main buckle portion and the first housing.

[0018] In one embodiment, one of the latching member and the locking member is provided with a slot, and the other is provided with a protrusion; the extending direction of the slot and the extending direction of the protrusion correspond to the rotation axis; when the locking member is in the second position, the protrusion is at least partially accommodated in the slot.

[0019] In one embodiment, the fastener includes a main fastener portion and a side block portion; the main fastener portion is rotatably connected to the first housing; 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 along a direction parallel to the rotation axis.

[0020] In one embodiment, the side blocks are connected to both sides of the main buckle; the locking member has the second stop surface and the recess respectively formed on both sides of the main buckle.

[0021] In one embodiment, the first housing includes a first main shell and a boss portion connected to the first main shell; the boss portion protrudes from the outer peripheral side of the first main shell; the boss portion has an opening; the fastener and the locking member are respectively movably inserted through the opening.

[0022] In one embodiment, the locking member further includes a connecting portion that is movably inserted through the opening of the boss portion; when the locking member moves to the second position, the connecting portion and the latching member form a stop engagement.

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.

[0049] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2 As shown, this application provides a connector for electrical mating with another connector. For simplicity and ease of understanding, the connector provided in this application is referred to as a first connector 100, and the other connector is referred to as a second connector 200. Understandably, the first connector 100 and the second connector 200 are combined to form a connector assembly.

[0051] 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 connected, 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Specifically, in combination Figure 6 As 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 second preset distance.

[0058] 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.

[0059] 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.

[0060] 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 rotatably disposed relative to the first housing 11 along a 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 movably 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 is provided with a first stop surface 151, and the other is provided with a second stop surface 171 and a recess 172. When the snap-fit ​​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 each other and spaced apart by a first 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 positioned opposite to the recess 172.

[0061] The connector of this application, combined with Figure 7 and Figure 8As 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.

[0062] 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, the first stop surface 151 and the second stop surface 171 are opposite each other and spaced apart by a first preset distance, allowing the latching member 15 to rotate between the free position and the first operating position. When the latching member 15 is in the free position due to the action of the elastic force, 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, so that the first connector 100 and the second connector 200 are kept in a fully mated state, thereby ensuring the stable transmission of signals and load current.

[0063] 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.

[0064] 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.

[0065] Combination Figure 11a and Figure 11bAs 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 operating the movement of the locking member 17 relative to the first housing 11. When the locking member 17 is in the second position, the recess 172 is opposite to the first stop surface 151, giving the latching member 15, which is in the first operating position, further room for movement. 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.

[0066] 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.

[0067] Understandably, when the locking member 17 is in the first position relative to the first housing 11, the user can only operate the latching member 15 from the free position to the first operating position. At this time, the first housing 11 can only move relative to the second housing 21 to the unlocked transition position. After the user operates the latching member 15 from the free position to the first operating position and immediately releases it, the latching member 15 cannot avoid the fourth stop surface 252. After the latching member 15 is operated to the first operating position, the user needs to further switch the locking member 17 from the first position to the second position so that the latching member 15 can rotate to the second operating position and avoid the fourth stop surface 252. The time period between the signal terminal separation point and the power terminal separation point includes the operation time for switching the locking member 17 from the first position to the second position, thereby ensuring that the control module and switching devices receive the necessary response time, avoiding the occurrence of arc discharge when the first power terminal 13 and the second power terminal 23 are separated.

[0068] Understandably, the recess 172 is a structure capable of avoiding the first stop surface 151. Exemplarily, the recess 172 is recessed relative to the second stop surface 171.

[0069] 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.

[0070] In some implementations, combined Figure 7 As shown, the latching member 15 includes a main latching portion 152 and a fastening portion 153 connected to the main latching portion 152. The main latching portion 152 is rotatably connected to the first housing 11. The fastening 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 fastening 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 fastening portion 153 and the first power terminal 13 decreases sequentially. Correspondingly, 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. Exemplarily, the elastic member 16 abuts between the main latching portion 152 and the first main housing 111.

[0071] For example, combined Figure 7 As 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.

[0072] 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.

[0073] 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.

[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 first force-applying part 154 connected to the main latching part 152. The first 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 first force-applying part 154 to rotate the latching member 15 from the free position to the first operating position, or to move the latching member 15 from the first operating position to the second operating position.

[0077] In some implementations, combined Figure 4a and Figure 4b As 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 embodiments, the locking member 17 is slidably disposed relative to the first housing 11. Exemplarily, the sliding direction of the locking member 17 is substantially parallel to the insertion direction F1.

[0083] In some implementations, combined Figure 5 and Figure 8 As shown, the locking member 17 includes a mounting portion 174 and a second 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 second force-applying portion 173, causing the locking member 17 to move from a first position to a second position, or to move the locking member 17 from a second position to a first position.

[0084] In some embodiments, the second force-applying part 173 is disposed adjacent to the first force-applying part 154 along the insertion direction F1.

[0085] For example, the first force-applying part 154 and the second 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 first force-applying part 154 or the second 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 first force-applying part 154 or the second force-applying part 173.

[0086] For example, combined Figure 2 As shown, the first force-applying part 154 is disposed downstream of the second 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.

[0087] For example, combined Figure 14b and Figure 15a As shown, the first force-applying part 154 can also be disposed upstream of the second force-applying part 173 along the insertion direction F1, and the locking member 17 in the first position can slide to the second position along the insertion direction F1.

[0088] In some implementations, combined Figure 7 As shown, the second force-applying part 173 is at least partially disposed outside the first housing 11. Along the insertion direction F1, the outer surface of the second 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 second 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 second 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.

[0089] For example, combined Figure 5 and Figure 7 As shown, along the insertion direction F1, the outer surface of the second force-applying part 173 has a concave-convex transition, which helps to increase the friction between the finger and the second force-applying part 173.

[0090] 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.

[0091] 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.

[0092] For example, combined Figure 5As shown, the connecting portion 175 connects the mounting portion 174 and the second 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.

[0093] 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.

[0094] In some implementations, combined Figure 5 As shown, the locking member 17 also includes a contact portion 177 connected to the mounting portion 174. 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.

[0095] In some other embodiments, the locking member 17 may also be rotatably disposed relative to the first housing 11 along the outer circumference of the first housing 11. The fourth stop surface 252 and the recess 172 are disposed adjacent to each other in the circumferential direction.

[0096] 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.

[0097] In other embodiments, combined Figures 14b to 15b As shown, for the free position, the first operating position, and the second operating position, the distance between the engaging part 153 and the first power terminal 13 can also increase sequentially. Correspondingly, in conjunction with... Figure 13 As shown, 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.

[0098] Optionally, combined Figure 14a and Figure 15a As shown, the locking member 17 is provided with a sliding groove 178. A shaft 18 passes through the sliding groove 178. The extending direction of the sliding groove 178 is approximately parallel to the insertion direction F1. Understandably, the shaft 18 cooperates with the sliding groove 178 to maintain connection between the locking member 17 and the first housing 11, while allowing the locking member 17 to slide relative to the first housing 11. The above embodiments are merely descriptions of preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and improvements made to the technical solutions of this application by those skilled in the art without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
