Abstract
Description
Technical Field
[0001] The present disclosure relates to a safety connection structure and a safety connector. Background Art
[0002] As connector products continue to evolve, connector safety is increasingly becoming a priority. For example, according to IEC60335, when the output voltage exceeds 42 volts, the metal on the connector output terminals must not be exposed, or the test voltage for exposed metal must not exceed 42 volts. While existing connectors feature protective covers or are designed to retract the metal terminals for increased safety, the slender structure of the probes used during safety testing means that even connectors with non-exposed metal can still be touched by the probes, failing to comply with safety regulations such as IEC60335. Summary of the Invention
[0003] In view of this, an object of the present disclosure is to provide a secure connection structure and a secure connector that can solve the above-mentioned problems.
[0004] In order to achieve the above-mentioned purpose, according to one embodiment of the present disclosure, a safety connection structure includes a first connector and a second connector detachably connected to the first connector. The first connector includes a first outer shell, a first inner shell, a first conductive terminal, a first connecting bridge and a conductive rod. The first inner shell is located in the first outer shell. The first inner shell has a first through-hole. The first conductive terminal is located in the first through-hole in the first inner shell. The first connecting bridge is accommodated in the first outer shell and can rotate in the first outer shell. The conductive rod passes through the first connecting bridge and is fixed to the first connecting bridge, and protrudes outward from the first outer shell along a coupling direction. The second connector includes a second outer shell and a second conductive terminal. The second outer shell is configured to couple with the first outer shell. The second conductive terminal is located in the second outer shell. When the first connector is not connected to the second connector, the conductive rod is not aligned with the first through-hole and is in a non-conductive state with the first conductive terminal in the first through-hole. When the first connector is connected to the second connector along the coupling direction, the conductive rod is connected to the second conductive terminal, and the first outer shell rotates relative to the second outer shell about a rotation axis parallel to the coupling direction. The first inner shell rotates with the first outer shell until the first through-hole is aligned with the conductive rod. The first connector and the second connector are further pushed together along the coupling direction, so that the conductive rod passes through the first through-hole and connects to the first conductive terminal, so that the first conductive terminal is in a conductive state with the second conductive terminal through the conductive rod.
[0005] In one or more embodiments of the present disclosure, the first connector includes a first guiding mechanism, and the second connector includes a second guiding mechanism. The first guiding mechanism and the second guiding mechanism are used to assist the first connector and the second connector in relative movement or rotation.
[0006] In one or more embodiments of the present disclosure, the first guide mechanism includes a groove disposed on the outer surface of the first housing. The groove comprises a first groove, a second groove communicating with the first groove, and a recess at the end of the second groove. The second guide mechanism includes a cantilever disposed on the outer surface of the second housing. The cantilever has a free end and a fixed end fixed to the second housing. When the first connector and the second connector move or rotate relative to each other, the free end of the cantilever moves within the first and second grooves.
[0007] In one or more embodiments of the present disclosure, the second guide mechanism includes a groove disposed on the outer surface of the second housing. The groove comprises a first groove, a second groove communicating with the first groove, and a recess at the end of the second groove. The first guide mechanism includes a cantilever disposed on the outer surface of the first housing. The cantilever has a free end and a fixed end fixed to the first housing. When the first connector and the second connector move or rotate relative to each other, the free end of the cantilever moves within the first and second grooves.
[0008] In one or more embodiments of the present disclosure, when the first shell rotates relative to the second shell, the free end of the cantilever moves in the first groove; when the first through-hole is aligned with the conductive rod and the first connector and the second connector are further pushed together along the coupling direction, the free end of the cantilever moves in the second groove.
[0009] In one or more embodiments of the present disclosure, the second groove has a recess at an end of the second groove. When the first connector and the second connector are further pushed together along the coupling direction, the free end of the cantilever moves in the second groove, so that the free end of the cantilever is locked in the recess.
[0010] In one or more embodiments of the present disclosure, the first inner shell further includes an arcuate groove disposed on a surface adjacent to the first connecting bridge, and the first through-hole of the first inner shell is connected to one end of the arcuate groove.
[0011] In one or more embodiments of the present disclosure, the second connector further includes a second inner housing located within the second outer housing, wherein the second inner housing has a second through hole for accommodating the second conductive terminal.
[0012] In one or more embodiments of the present disclosure, the second connector further includes a second connecting bridge, and the conductive rod passes through the second connecting bridge and is connected to the second conductive terminal.
[0013] In one or more embodiments of the present disclosure, the first connector further includes an elastic member disposed between the first inner housing and the first connecting bridge.
[0014] In order to achieve the above-mentioned purpose, according to one embodiment of the present disclosure, a safety connector includes an outer shell, an inner shell, a conductive terminal, a connecting bridge and a conductive rod. The inner shell is located inside the outer shell. The inner shell has a through-hole. The conductive terminal is located in the through-hole of the inner shell. The connecting bridge is accommodated in the outer shell and is configured to be rotatable inside the outer shell. The conductive rod passes through the connecting bridge and is fixed to the connecting bridge, and protrudes outward from the outer shell along the coupling direction. When the safety connector is in an unconnected state, the conductive rod is not aligned with the through-hole and is in a non-conductive state with the conductive terminal in the through-hole. When the inner shell is rotated relative to the connecting bridge with an axis of rotation parallel to the coupling direction until the through-hole is aligned with the conductive rod, and the inner shell and the connecting bridge are further pushed together along the coupling direction, the conductive rod passes through the through-hole and connects the conductive terminal, so that the conductive terminal and the conductive rod are in a conductive state.
[0015] In one or more embodiments of the present disclosure, the outer surface of the housing has a first groove, a second groove connected to the first groove, and a groove located at an end of the second groove.
[0016] In one or more embodiments of the present disclosure, the outer surface of the housing has a cantilever having a free end and a fixed end fixed to the housing.
[0017] In one or more embodiments of the present disclosure, the inner shell further includes an arcuate groove disposed on a surface adjacent to the connecting bridge. A through-hole in the inner shell is connected to one end of the arcuate groove; when the inner shell rotates relative to the connecting bridge, the end of the conductive rod adjacent to the inner shell moves along the arcuate groove.
[0018] In one or more embodiments of the present disclosure, the safety connector further includes an elastic member disposed between the inner housing and the connecting bridge.
[0019] In summary, in the safety connection structure and safety connector disclosed herein, because the first inner shell has a first perforation, when a user couples the first and second connectors, the conductive rod can first be stopped by the arcuate groove and prevented from immediately passing through the first perforation and contacting the first conductive terminal, thereby achieving the effect of preventing electrical conduction while the conductive rod remains exposed. In the safety connection structure and safety connector disclosed herein, because the arcuate groove has an arc shape and is configured for the conductive rod to abut, when the first and second connectors rotate relative to each other, the arcuate groove can guide the conductive rod to move within the arcuate groove. Overall, the safety connection structure and safety connector disclosed herein improve safety for users when using the connector.

[0074] The following drawings illustrate various embodiments of the present disclosure. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be construed as limiting the present disclosure. In other words, these practical details are not essential for some embodiments of the present disclosure.

[0075] The secure connection structure 100 according to one or more embodiments of the present disclosure will be described in detail below.
[0076] Please refer to Figure 1 . Figure 1 FIG is a perspective view of a safety connection structure 100 according to an embodiment of the present disclosure. Figure 1As shown, in this embodiment, the safety connection structure 100 includes a first connector 110 and a second connector 120. The first connector 110 is detachably connected to the second connector 120 and is configured to rotate relative to the second connector 120. The first connector 110 and the second connector 120 are configured to couple with each other. The first connector 110 includes a first housing 111, a conductive rod CR, and an output cable OPC. The second connector 120 includes a second housing 121 and an input cable IPC. In this embodiment, the output cable OPC is electrically connected to the input cable IPC via the conductive rod CR. The output cable OPC is connected to the first housing 111. The output cable OPC protrudes from the first housing 111 and extends away from the conductive rod CR. The conductive rod CR protrudes outward from the first housing 111 along a coupling direction (e.g., direction X) to couple with the second connector 120. The second housing 121 is configured to couple with the first housing 111 and accommodate the conductive rod CR. The coupling direction refers to the direction in which the first connector 110 moves toward the second connector 120 to enable connection.
[0077] In some embodiments, the first connector 110 and the second connector 120 each have a corresponding first guide mechanism and a corresponding second guide mechanism to assist the first connector 110 and the second connector 120 in performing relative movement or rotation and other connection operations. In this embodiment, the first guide mechanism is implemented as a groove 112, and the second guide mechanism is implemented as a cantilever 122.
[0078] like Figure 1 As shown in the embodiment, the first connector 110 has a groove 112. The first housing 111 has an outer surface 111a. The groove 112 is provided on the outer surface 111a of the first housing 111, and the groove 112 has an inlet ET, a first groove 1121, and a second groove 1122. The inlet ET is connected to one end of the first groove 1121, the second groove 1122 is connected to the other end of the first groove 1121, and a groove 1123 is provided at the end of the second groove 1122. Figure 1 As shown in the embodiment, the structural configuration of the inlet ET, the first trench 1121 and the second trench 1122 makes the trench 112 have a zigzag shape.
[0079] like Figure 1As shown in the embodiment, the second connector 120 includes a cantilever 122. The second housing 121 has an outer surface 121a. The cantilever 122 is disposed on the outer surface 121a of the second housing 121, and the cantilever 122 has a fixed end XE and a free end FE. The fixed end XE is disposed on the outer surface 121a of the second housing 121. The free end FE is located at an end of the cantilever 122 away from the second housing 121. The free end FE of the cantilever 122 is configured to move in the groove 112 (for example, the free end FE of the cantilever 122 is configured to move in the first groove 1121 and the second groove 1122), so that the first connector 110 and the second connector 120 are connected at Figure 1 When the second connector 120 and the first connector 110 are coupled together along a direction (eg, direction X), the free end FE of the cantilever 122 moves in the second groove 1122. Figure 1 As shown in the embodiment, when the first connector 110 and the second connector 120 are connected, the free end FE of the cantilever 122 enters the first groove 1121 and the second groove 1122 through the entrance ET and is snapped into the groove 1123, so that the first connector 110 and the second connector 120 can remain positioned after connection without being separated.
[0080] In some embodiments, the first connector 110 is a power output terminal of the safety connection structure 100, and the second connector 120 is a power receiving terminal of the safety connection structure 100. In some embodiments, the first connector 110 is a power receiving terminal of the safety connection structure 100, and the second connector 120 is a power output terminal of the safety connection structure 100.
[0081] like Figure 1 As shown, in some embodiments, the number of the conductive rods CR is two. However, the present disclosure is not intended to limit the number of the conductive rods CR, and the number of the conductive rods CR can be set to an appropriate number based on different design considerations.
[0082] In other embodiments, the first guiding mechanism and the second guiding mechanism may also be implemented in other appropriate ways respectively. In this embodiment, the first connector 110 includes a groove 112 to combine with the cantilever 122 correspondingly provided on the second connector 120. In other embodiments, the first connector 110 includes a groove and a cantilever, which may be combined with the cantilever and groove correspondingly provided on the second connector 120, respectively. In other embodiments, the first connector 110 may have two grooves arranged opposite to each other on the outer surface 111a, and the second connector 120 may include two cantilevers arranged corresponding to the above-mentioned two grooves. However, the present disclosure is not intended to limit the number of grooves and cantilevers. In another embodiment, the first connector 110 includes a cantilever to combine with the groove correspondingly provided on the second connector 120. In addition, the groove and the cantilever may also be respectively provided at appropriate positions on the outer surface 111a or the outer surface 121a, and their shapes may be adjusted accordingly. In another embodiment, the groove and / or cantilever of the first connector 110 is disposed on the first adjacent surface 111b of the outer surface 111a. When the first connector 110 is connected to the second connector 120, the first adjacent surface 111b is adjacent to the second adjacent surface 121b of the outer surface 121a of the second connector 120, thereby engaging with the corresponding cantilever and / or groove disposed on the second adjacent surface 121b. In another embodiment, the groove may be disposed beneath the outer surface of the connector, without exposing the groove-like structure.
[0083] Please refer to Figure 2 . Figure 2 FIG1 is an exploded view of a safety connection structure 100 according to an embodiment of the present disclosure. In this embodiment, the first connector 110 further includes a first inner shell 113, a first connecting bridge 114, a first conductive terminal 115, and an elastic member 116. The second connector 120 further includes a second inner shell 123, a second connecting bridge 124, and a second conductive terminal 125. The first inner shell 113 is located within the first outer shell 111. The first inner shell 113 has an arc-shaped groove 1131 and a first through-hole 1132 (see FIG1). Figure 3). An arcuate groove 1131 is provided on a surface adjacent to the first connecting bridge 114. The conductive rod CR is configured to move along the arcuate groove 1131. The first conductive terminal 115 is located in the first through-hole 1132 of the first inner shell 113 and is electrically connected to the output cable OPC. The elastic member 116 is provided between the first inner shell 113 and the first connecting bridge 114. The second inner shell 123 is located within the second outer shell 121. The conductive rod CR passes through the first connecting bridge 114 and is fixed to the first connecting bridge 114 in an appropriate position. The conductive rod CR extends beyond both ends of the first connecting bridge 114. When the first connector 110 and the second connector 120 are properly connected, the conductive rod CR can be connected to the first conductive terminal 115 and the second conductive terminal 125 respectively. However, when the first connector 110 and the second connector 120 are not connected or are not properly connected, the conductive rod CR is not connected to the first conductive terminal 115 and does not conduct electricity. The second conductive terminal 125 is located in the second inner shell 123.
[0084] like Figure 2 As shown, the first connecting bridge 114 has several through-holes, referred to as through-holes TH to distinguish them from other components. The second connecting bridge 124 has several through-holes, referred to as through-holes TH to distinguish them from other components. The conductive rod CR has a first end E1 and a second end E2. The first end E1 of the conductive rod CR passes through the first connecting bridge 114 via the through-holes TH of the first connecting bridge 114 and extends beyond the first connecting bridge 114 by an appropriate length, enabling operation to connect to the first conductive terminal 115. The second end E2 of the conductive rod CR also extends beyond the first connecting bridge 114 by an appropriate length. When the first connector 110 and the second connector 120 are connected, the second end E2 of the conductive rod CR can pass through the second connecting bridge 124 via the through-holes TH of the second connecting bridge 124. The first end E1 is the end of the conductive rod CR closest to the output cable OPC, and the second end E2 is the end of the conductive rod CR closest to the input cable IPC. The first end E1 of the conductive rod CR moves along the arcuate groove 1131.
[0085] like Figure 2 As shown, the second inner shell 123 has a second through hole 1232 configured for the conductive rod CR to pass through. The second conductive terminal 125 is accommodated in the second through hole 1232 of the second inner shell 123 .
[0086] like Figure 2 As shown, in some embodiments, the number of first conductive terminals 115 and second conductive terminals 125 is two each, and the number of second through-holes 1232 is two. Specifically, the number of first conductive terminals 115, second conductive terminals 125, and second through-holes 1232 is substantially equal to the number of conductive rods CR. However, the present disclosure is not intended to limit the number of first conductive terminals 115, second conductive terminals 125, and second through-holes 1232.
[0087] Please continue to refer to Figure 3 . Figure 3 FIG1 is a perspective view of a first inner shell 113 according to an embodiment of the present disclosure. The first inner shell 113 further includes a first through-hole 1132 connected to one end of the arcuate groove 1131. In some embodiments, the first through-hole 1132 of the first inner shell 113 extends through the first inner shell 113 along a coupling direction (e.g., direction X). In some embodiments, the first conductive terminal 115 is received in the first through-hole 1132 of the first inner shell 113. In some embodiments, the conductive rod CR is configured to abut the arcuate groove 1131. The first connecting bridge 114 and the conductive rod CR fixed to the first connecting bridge 114 can be rotated relative to the first inner shell 113 to align the conductive rod CR with the first through-hole 1132. This allows the conductive rod CR to contact the first conductive terminal 115 when pushed into the first through-hole 1132 and to disengage the conductive rod CR from the first through-hole 1132.
[0088] In some embodiments, the first inner shell 113 may not be provided with the arc-shaped groove 1131. In some other embodiments, the first inner shell 113 may also adopt a circular groove or other suitable guiding mechanism, so that the conductive rod CR moves along the edge of the circular groove or multiple guiding mechanisms, and can move the conductive rod CR to align with or offset from the first through hole 1132.
[0089] In some embodiments, there are two first through-holes 1132. Specifically, the number of first through-holes 1132 is substantially equal to the number of conductive rods CR and the number of arc-shaped grooves 1131. However, the present disclosure is not intended to limit the number of first through-holes 1132.
[0090] The following will describe in detail the secure connection structure 100 in the first state S1, the second state S2, the third state S3 and the fourth state S4 of the present disclosure. In order to obtain a better understanding of the secure connection structure 100 in the first state S1, please refer to Figure 4 as well as Figure 5 To obtain a better understanding of the secure connection structure 100 in the second state S2, please refer to Figure 6 as well as Figure 7 To obtain a better understanding of the secure connection structure 100 in the third state S3, please refer to Figure 8 as well as Figure 9 To obtain a better understanding of the secure connection structure 100 in the fourth state S4, please refer to Figure 10 as well as Figure 11 .
[0091] Please continue to refer to Figure 4 . Figure 4According to an embodiment of the present disclosure, Figure 1 A three-dimensional cross-sectional view of the safety connection structure 100 in the first state S1 along the cutting line AA'. Figure 4 As shown, in this embodiment, the first state S1 refers to a state in which the first connector 110 has not yet contacted the second connector 120. Figure 4 As shown, the conductive rod CR passes through the first connecting bridge 114, and the conductive rod CR extends from the first shell 111 along a coupling direction toward the second connector 120. The conductive rod CR is fixed to the first connecting bridge 114. In detail, when the safety connection structure 100 is in the first state S1, the first end E1 of the conductive rod CR is located in the arc groove 1131 but is misaligned with the first through-hole 1132. The conductive rod CR cannot contact the first conductive terminal 115, resulting in a non-conductive state between the two. The second end E2 of the conductive rod CR does not pass through the through-hole TH of the second connecting bridge 124 and the second through-hole 1232 of the second inner shell 123. Figure 4 As shown, when the safety connection structure 100 is in the first state S1, the conductive rod CR does not contact the first conductive terminal 115 and the second conductive terminal 125, so that the output cable OPC and the input cable IPC are not conductive. Figure 4 As shown, the elastic member 116 has elastic restoring force, so that the elastic member 116 abuts between the first outer shell 111 and the first connecting bridge 114. In another embodiment, the elastic member 116 may also be disposed between the first inner shell 113 and the first connecting bridge 114.
[0092] like Figure 4 As shown, in some embodiments, a plurality of conductive rods CR are arranged along a direction (eg, direction Z).
[0093] like Figure 4 As shown, the second through hole 1232 of the second inner shell 123 is aligned with the through hole TH of the second connecting bridge 124 in a combining direction (eg, direction X) to accommodate the conductive rod CR.
[0094] like Figure 4 As shown, in some embodiments, the second conductive terminal 125 is tubular and has a cavity, and the cavity of the second conductive terminal 125 is configured to accommodate the portion of the conductive rod CR near the second end E2 for connection and electrical conduction. In other embodiments, the second conductive terminal 125 can also be configured as a rod or other suitable shape, capable of connecting with the contact surface of the conductive rod CR for electrical conduction.
[0095] Please refer to Figure 5 . Figure 5 According to an embodiment of the present disclosure, Figure 1 A cross-sectional view of the first connector 110 in the first state S1 along the cutting line BB'. Figure 5As shown, in this embodiment, when the safety connection structure 100 is in the first state S1, the two conductive rods CR respectively abut against the two arc-shaped grooves 1131. In some embodiments, the two conductive rods CR respectively abut against one end of the two arc-shaped grooves 1131 and are not aligned with the first through-holes 1132 at the other end of the two arc-shaped grooves 1131. Figure 5 It can be clearly seen that the conductive rod CR is not aligned with the first through hole 1132 and cannot contact the first conductive terminal 115 .
[0096] like Figure 5 As shown, in some embodiments, the first conductive terminal 115 is disposed on the inner wall of the first through-hole 1132. In some embodiments, the first conductive terminal 115 is tubular and has a cavity, and the cavity of the first conductive terminal 115 is configured to accommodate the portion of the conductive rod CR near the first end E1 for connection and electrical conduction. In other embodiments, the first conductive terminal 115 can also be configured as a rod or other suitable shape, capable of connecting with the contact surface of the conductive rod CR for electrical conduction.
[0097] like Figure 4 as well as Figure 5 As shown, a plurality of conductive rods CR are arranged along a direction (e.g., direction Z), and a plurality of first conductive terminals 115 are arranged along a direction (e.g., direction Y). Therefore, in the first state S1, by staggering the positions of the conductive rods CR and the first conductive terminals 115, the conductive rods CR are not connected to the power supply via the first conductive terminals 115, thus eliminating safety concerns.
[0098] Please refer to Figure 6 . Figure 6 According to an embodiment of the present disclosure, Figure 1 A three-dimensional cross-sectional view of the safety connection structure 100 in the second state S2 along the cutting line AA'. Figure 6As shown, in this embodiment, the second state S2 refers to a state in which the first connector 110 contacts the second connector 120 but the output cable OPC and the input cable IPC are not yet electrically conductive. Specifically, when the safety connection structure 100 changes from the first state S1 to the second state S2, the first connector 110 moves relative to the second connector 120 along the coupling direction (i.e., movement direction D1), and the second connector 120 moves relative to the first connector 110 along the coupling direction (i.e., movement direction D2). In other words, when the safety connection structure 100 changes from the first state S1 to the second state S2, the first connector 110 and the second connector 120 move toward each other. In some embodiments, the first connector 110 is relatively stationary (e.g., fixed to a power supply device), and the second connector 120 moves toward the first connector 110 along the movement direction D2. In some embodiments, the second connector 120 is relatively stationary (e.g., fixed to a charged device), and the first connector 110 moves toward the second connector 120 along the movement direction D1.
[0099] Specifically, when the safety connection structure 100 is in the second state S2, the first end E1 of the conductive rod CR still abuts against the arc groove 1131, but is not aligned with the first through hole 1132 and does not contact the first conductive terminal 115. The second end E2 of the conductive rod CR passes through the through hole TH of the second connecting bridge 124 and the second through hole 1232 of the second inner shell 123. Figure 6 As shown, when the safety connection structure 100 is in the second state S2, the conductive rod CR does not contact the first conductive terminal 115 but contacts the second conductive terminal 125, so that the output cable OPC and the input cable IPC are still not conductive. Figure 6 As shown, when the safety connection structure 100 is in the second state S2 , the free end FE of the cantilever 122 enters the groove 112 through the entrance ET.
[0100] In one usage scenario, a user grasps the first connector 110 and the second connector 120 with both hands and moves the first connector 110 and the second connector 120 toward each other, causing the secure connection structure 100 to transition from the first state S1 to the second state S2 and allowing the free end FE of the cantilever 122 to enter the groove 112 through the entrance ET. In some embodiments, the first connector 110 moves toward the second connector 120 along a movement direction D1, and the second connector 120 moves toward the first connector 110 along a movement direction D2. In some embodiments, the first connector 110 is relatively stationary (e.g., fixed to a power supply device), and the user grasps the second connector 120 and moves the second connector 120 toward the first connector 110 along a movement direction D2. In some embodiments, the second connector 120 is relatively stationary (e.g., fixed to a charged device), and the user grasps the first connector 110 and moves the first connector 110 toward the second connector 120 along a movement direction D1.
[0101] like Figure 6 As shown, when the safety connection structure 100 is in the second state S2, the second end E2 of the conductive rod CR is housed in the cavity of the second conductive terminal 125 and does not contact the input cable IPC. However, the present disclosure is not limited to this. For example, the second end E2 of the conductive rod CR may contact the input cable IPC when housed in the cavity of the second conductive terminal 125.
[0102] Please refer to Figure 7 . Figure 7 According to an embodiment of the present disclosure, Figure 1 A cross-sectional view of the first connector 110 in the second state S2 along the cutting line BB'. Figure 7 The structural configuration of the first connector 110 is similar to that of Figure 5 The structure and configuration of the first connector 110 are the same, so they will not be described again here.
[0103] Please refer to Figure 8 . Figure 8 According to an embodiment of the present disclosure, Figure 1 A three-dimensional cross-sectional view of the safety connection structure 100 in the third state S3 along the cutting line AA'. Figure 8As shown, in this embodiment, the third state S3 refers to the first connector 110 and the second connector 120 rotating relative to each other after the first connector 110 contacts the second connector 120, but at this time the output cable OPC and the input cable IPC are not yet conductive. Specifically, when the safety connection structure 100 changes from the second state S2 to the third state S3, the first connector 110 rotates relative to the second connector 120 along the rotation direction RT1, and the second connector 120 rotates relative to the first connector 110 along the rotation direction RT2. In other words, when the safety connection structure 100 changes from the second state S2 to the third state S3, the first connector 110 and the second connector 120 rotate in a direction parallel to a coupling direction (for example, Figure 8 In some embodiments, the first connector 110 is stationary (eg, fixed to a power supply device), and the second connector 120 is parallel to a coupling direction (eg, Figure 8 In some embodiments, the second connector 120 is stationary (e.g., fixed to the charged device), and the first connector 110 is parallel to a coupling direction (e.g., Figure 8 The rotation axis (direction X) rotates relative to the second connector 120 along the rotation direction RT1.
[0104] like Figure 8 As shown, when the safety connection structure 100 changes from the second state S2 to the third state S3, the free end FE of the cantilever 122 moves in the first groove 1121 along the rotation direction RT2, so that the free end FE of the cantilever 122 moves from the end of the first groove 1121 near the inlet ET to the end of the first groove 1121 near the second groove 1122. When the first connector 110 rotates relative to the second connector 120, the first outer shell 111 drives the first through-hole 1132 of the first inner shell 113 to rotate along the rotation direction RT1, so that the first through-hole 1132 is in a coupling direction (for example, Figure 8 The conductive rod CR is aligned with the first end E1 in the direction X) of the conductive rod, but the conductive rod CR does not yet contact the first conductive terminal 115. The second end E2 of the conductive rod CR still passes through the through hole TH of the second connecting bridge 124 and the second through hole 1232 of the second inner shell 123. Figure 8 As shown, when the safety connection structure 100 is in the third state S3 , the conductive rod CR does not contact the first conductive terminal 115 but contacts the second conductive terminal 125 , so that the output cable OPC and the input cable IPC are still not conductive.
[0105] In one usage scenario, a user grasps the first connector 110 and the second connector 120 with both hands and rotates the first connector 110 and the second connector 120 relative to each other, causing the secure connection structure 100 to transition from the second state S2 to the third state S3 and causing the free end FE of the cantilever 122 to move from the end of the first groove 1121 near the inlet ET to the end of the first groove 1121 near the second groove 1122. In some embodiments, the first connector 110 rotates relative to the second connector 120 along a rotational direction RT1, and the second connector 120 rotates relative to the first connector 110 along a rotational direction RT2. In some embodiments, the first connector 110 is relatively stationary, and the user grasps the second connector 120 to rotate the second connector 120 relative to the first connector 110 along a rotational direction RT2. In some embodiments, the second connector 120 is relatively stationary, and the user grasps the first connector 110 to rotate the first connector 110 relative to the second connector 120 along a rotational direction RT1.
[0106] In some embodiments, the first inner shell 113 is fixedly disposed within the first outer shell 111, and the first connecting bridge 114 is rotatably disposed within the first outer shell 111. Driven by the first outer shell 111, the first inner shell 113 can rotate relative to the first connecting bridge 114 about a rotation axis parallel to a coupling direction (e.g., direction X), thereby aligning the first through-hole 1132 of the first inner shell 113 with the conductive rod CR.
[0107] like Figure 8 As shown, the output cable OPC contacts the first conductive terminal 115 , and the input cable IPC contacts the second conductive terminal 125 .
[0108] Please refer to Figure 9 . Figure 9 According to an embodiment of the present disclosure, Figure 1 A cross-sectional view of the first connector 110 in the third state S3 along the cutting line BB'. Figure 9 The structural configuration shown is similar to Figure 7 The illustrated configuration is generally similar, differing in that the first connector 110 rotates relative to the second connector 120 along the rotational direction RT1. When the secure connection structure 100 is in the third state S3, the two conductive bars CR are aligned with the first through-holes 1132 located in the two arc-shaped grooves 1131. Consequently, the two conductive bars CR are also aligned with the first conductive terminals 115.
[0109] Please refer to Figure 10 . Figure 10 According to an embodiment of the present disclosure, Figure 1A three-dimensional cross-sectional view of the safety connection structure 100 in the fourth state S4 along the cutting line AA'. Figure 10 As shown, in this embodiment, the fourth state S4 refers to a state in which the first connector 110 contacts the second connector 120 and the output cable OPC is in electrical contact with the input cable IPC. Specifically, when the safety connection structure 100 transitions from the third state S3 to the fourth state S4, the first connector 110 continues to move relative to the second connector 120 along the movement direction D1, and the second connector 120 continues to move relative to the first connector 110 along the movement direction D2. In other words, when the safety connection structure 100 transitions from the third state S3 to the fourth state S4, the first connector 110 and the second connector 120 move toward each other. In some embodiments, the first connector 110 is relatively stationary, and the second connector 120 moves toward the first connector 110 along the movement direction D2. In some embodiments, the second connector 120 is relatively stationary, and the first connector 110 moves toward the second connector 120 along the movement direction D1.
[0110] Specifically, when the safety connection structure 100 is in the fourth state S4, the first connector 110 and the second connector 120 are further pushed together along the coupling direction, and the first end E1 of the conductive rod CR passes through the first through hole 1132 and contacts the first conductive terminal 115. The second end E2 of the conductive rod CR still passes through the through hole TH of the second connecting bridge 124 and the second through hole 1232 of the second inner shell 123 and contacts the second conductive terminal 125. Figure 10 As shown, when the safety connection structure 100 is in the fourth state S4, the conductive rod CR contacts the first conductive terminal 115 and the second conductive terminal 125 at the same time, and the first conductive terminal 115 can be in a conductive state with the second conductive terminal 125 through the conductive rod CR, so that the output cable OPC and the input cable IPC are conductive. Figure 10As shown, when the secure connection structure 100 transitions from the third state S3 to the fourth state S4, the first connector 110 and the second connector 120 move toward each other along a coupling direction (e.g., direction X), causing the free end FE of the cantilever 122 to move along the coupling direction within the second groove 1122. When the free end FE of the cantilever 122 abuts the end of the second groove 1122, the free end FE snaps into the groove 1123. At this point, the first connecting bridge 114 moves toward the first outer shell 111 (or first inner shell 113), compressing the elastic member 116. With the free end FE snapping into the groove 1123, the first connector 110 and the second connector 120, after being connected, remain positioned and prevent disengagement in the fourth state S4. In the fourth state S4, if the first connector 110 and the second connector 120 are pulled apart and the free end FE is disengaged from the groove 1123, the elastic member 116 will reset and move the first connecting bridge 114 away from the first outer shell 111 (or the first inner shell 113), so that the conductive rod CR can immediately stop contacting the first conductive terminal 115, thereby ensuring that the conductive rod CR is immediately in a non-conductive state.
[0111] In one usage scenario, a user grasps the first connector 110 and the second connector 120 with both hands and moves the first connector 110 and the second connector 120 toward each other, causing the secure connection structure 100 to transition from the third state S3 to the fourth state S4. The free end FE of the cantilever 122 moves along the second groove 1122 and snaps into the recess 1123. In some embodiments, the first connector 110 moves toward the second connector 120 along a movement direction D1, and the second connector 120 moves toward the first connector 110 along a movement direction D2. In some embodiments, the first connector 110 is relatively stationary, and the user grasps the second connector 120 and moves it toward the first connector 110 along a movement direction D2. In some embodiments, the second connector 120 is relatively stationary, and the user grasps the first connector 110 and moves it toward the second connector 120 along a movement direction D1. As a result, the second connector 120 is coupled to the first connector 110, ensuring electrical conductivity between the output cable OPC and the input cable IPC, and preventing the conductive rod CR from being exposed.
[0112] like Figure 10 As shown, when the safety connection structure 100 is in the fourth state S4, the first end E1 of the conductive rod CR is accommodated in the cavity of the first conductive terminal 115 without contacting the output cable OPC, and the second end E2 of the conductive rod CR is accommodated in the cavity of the second conductive terminal 125 without contacting the input cable IPC, but the present disclosure is not limited to this. For example, the first end E1 of the conductive rod CR may contact the output cable OPC, and the second end E2 of the conductive rod CR may contact the input cable IPC.
[0113] Please refer to Figure 11 . Figure 11 According to an embodiment of the present disclosure, Figure 1 The cross-sectional view of the first connector 110 in the fourth state S4 is taken along the cutting line BB'. Figure 11 The structural configuration shown is similar to Figure 9 The structural configuration shown is the same, so it will not be repeated here.
[0114] In some embodiments, the process of removing the second connector 120 from the first connector 110 is as follows. The safety connection structure 100 can be removed from the first connector 110 by changing from the fourth state S4 to the third state S3, to the second state S2, and then to the first state S1. When the safety connection structure 100 changes from the fourth state S4 to the third state S3, the first connector 110 and the second connector 120 are pulled apart along a coupling direction (e.g., direction X) and move in opposite directions. Because the elastic member 116 has an elastic restoring force, the first connecting bridge 114 is pushed away from the first inner shell 113. The first end E1 of the conductive rod CR fixed to the first connecting bridge 114 thus leaves the first through-hole 1132 and does not contact the first conductive terminal 115, thereby causing the first conductive terminal 115 and the conductive rod CR to be in a non-conductive state. When the safety connection structure 100 transitions from the third state S3 to the second state S2, the first connector 110 and the second connector 120 rotate relative to each other, and the first outer shell 111 drives the first inner shell 113 to rotate accordingly, causing the first through-hole 1132 to misalign with the conductive rod CR, leaving the first conductive terminal 115 and the conductive rod CR in a non-conductive state. When the safety connection structure 100 transitions from the second state S2 to the first state S1, the first connector 110 and the second connector 120 are further pulled apart along a coupling direction (e.g., direction X) and move away from each other, causing the conductive rod CR to separate from the second connector 120. The first conductive terminal 115 and the conductive rod CR remain in a non-conductive state. This allows the user to safely remove the second connector 120 from the first connector 110.
[0115] By using the safety connection structure 100 shown in the present disclosure, it can be ensured that when the conductive rod CR is exposed, the conductive rod CR and the first conductive terminal 115 are in a non-conductive state. Therefore, when the conductive rod CR is exposed, the conductive rod CR and the output cable OPC are in a non-conductive state, which can comply with various safety regulations and allow users to safely operate the safety connection structure 100 to avoid the risk of electric shock.
[0116] From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the safety connection structure and safety connector of the present disclosure, because the first inner shell has a first perforation, when the user operates the first connector and the second connector to couple, the conductive rod can first be stopped and does not immediately pass through the first perforation and contact the first conductive terminal, thereby achieving the effect of non-conductivity while the conductive rod is still exposed. In the safety connection structure and safety connector of the present disclosure, because the arcuate groove has an arc shape and is configured for the conductive rod to abut, when the first connector and the second connector rotate relative to each other, the arcuate groove can guide the conductive rod to move in the arcuate groove. Overall, the safety connection structure and safety connector of the present disclosure improve the safety of users when using the connector.
[0117] The foregoing summarizes the features of several embodiments so that those skilled in the art can better understand the methods of this disclosure. Those skilled in the art will appreciate that the foregoing can readily serve as a basis for designing or modifying other variations without departing from the spirit and scope of this disclosure, thereby achieving the same objectives and / or advantages as the embodiments described herein. The foregoing should be understood as illustrative of this disclosure, and its scope of protection should be determined by the claims.
