Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector and connector assembly. Background Technology

[0002] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and distribution cabinets) to downstream devices. They are commonly used to distribute main power to various electrical devices.

[0003] Existing electrical connectors typically enclose metal terminals in an insulating housing and require insertion into other electrical connectors to achieve electrical conduction. However, the connectors remain energized during insertion and removal, posing a risk of electric shock to operators. Utility Model Content

The housing has a first through hole penetrating the first protrusion and the base, and a second through hole penetrating the second protrusion and the base. The power supply terminal module is disposed within the first through hole and is used to conduct current. The signal terminal module includes a first signal terminal passing through the second protrusion and a second signal terminal located on the base.

[0011] The rotation of the connecting arm drives the connecting rod to move, so that the first guide slope pushes the second guide slope and drives the transmission component to press against the second signal terminal to switch to the disconnected state.

[0012] In one embodiment, the transmission component includes a first rod and a second rod, the first rod and the second rod being connected at an angle, the first rod being partially slidably disposed in the slide groove, and the first rod having a hook protruding toward the second signal terminal, the hook being used to abut against the second signal terminal and drive the second signal terminal to move.

[0013] In one embodiment, the groove wall of the slide is provided with a first boss, and one end of the transmission member is provided with a second boss, the second boss being slidable between the first boss and the bottom of the slide.

[0034] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and distribution cabinets) to downstream devices. They are commonly used to distribute main power to various electrical devices.

[0035] Existing electrical connectors typically enclose metal terminals in an insulating housing and require insertion into other electrical connectors to achieve electrical conduction. However, the connectors remain energized during insertion and removal, posing a risk of electric shock to operators.

[0036] This utility model proposes an electrical connector and connector assembly, which aims to disconnect the power when the electrical connector is plugged in or unplugged, so as to avoid damage to equipment and personnel caused by plugging and unplugging while the power is on.

[0037] Please see Figures 1 to 6In one embodiment of this utility model, the electrical connector 10 includes a housing 11, a power supply terminal module 12, and a signal terminal module 13. The housing 11 includes a base 111, a first protrusion 112, and a second protrusion 113. The first protrusion 112 and the second protrusion 113 are spaced apart on one surface of the base 111. The housing 11 has a first through hole penetrating the first protrusion 112 and the base 111, and a second through hole penetrating the second protrusion 113 and the base 111. The power supply terminal module 12 is disposed in the first through hole and is used to conduct current. The signal terminal module 13 is disposed in the second through hole and includes components passing through the second protrusion. The signal terminal module 13 has a first signal terminal 131 and a second signal terminal 132 located on the base 111. One end of the second signal terminal 132 has a conducting state that abuts against the first signal terminal 131 in a direction perpendicular to the axis of the second through hole and a disconnected state that moves away from the first signal terminal 131. The signal terminal module 13 is used to conduct signals. The other end of the second signal terminal 132 has a connecting part for electrical connection with a cable. The signal terminal module 13 has a conducting state and a disconnected state. In the conducting state, one end of the second signal terminal 132 is connected to the first signal terminal 131. In the disconnected state, one end of the second signal terminal 132 is separated from the first signal terminal 131.

[0038] In this embodiment, the electrical connector 10 is used as a wire end, and the outer shell 11 is made of an insulating material, such as hard plastic or hard rubber, to prevent current leakage through the outer shell 11 and causing short circuits or other problems. The outer shell 11 includes a base 111, a first protrusion 112, and a second protrusion 113. The base 111, the first protrusion 112, and the second protrusion 113 can be integrally formed by injection molding, or they can be connected as one piece by bonding or ultrasonic welding, etc., without further limitation. The signal terminal module 13 includes a separately disposed first signal terminal 131 and a second signal terminal 132. The first signal terminal 131 is located on the second protrusion 113 and is used to connect with the current terminal of another electrical connector 10 to achieve signal conduction. The second signal terminal 132 is located on the base 111 and has an open state away from the first signal terminal 131 along the length direction of the housing 11 and an on state abutting the first signal terminal 131 along the length direction. The other end of the second signal terminal 132 has a riveting structure for connecting to an electrical wire to transmit signals. Therefore, the second signal terminal 132 can be switched to the open state before plugging or unplugging the electrical connector 10, thereby de-energizing the electrical connector 10 and improving the safety factor during plugging and unplugging.

[0039] The power supply terminal module 12 is located in the first through hole and is used to conduct current. The power supply terminal module 12 includes a tubular metal terminal, an insulating post, and an annular terminal. The tubular metal terminal has a tubular structure with a through-hole inside. The material can be copper or aluminum, etc. The tubular metal terminal passes through the through hole, and the connection between the tubular metal terminal and the hole wall can be a snap-fit ​​connection or a plug-in connection. The insulating post passes through the cavity of the tubular metal terminal and is connected to the cavity wall. Furthermore, one end of the insulating post is detachably connected to the cavity wall, such as by a threaded connection or a plug-in connection. The insulating post is made of insulating material such as silicone or rubber to prevent accidental electric shock caused by finger contact. One end of the insulating post is connected to the cavity wall of the receiving cavity, thereby dividing the receiving cavity inside the tubular metal terminal into a first receiving cavity and a second receiving cavity. The other end of the insulating post extends from the cavity wall to the opening of the first receiving cavity. The opening of the first receiving cavity is used to insert another electrical connector 10. The annular terminal is disposed on the cavity wall of the first receiving cavity. The second receiving cavity is used to solder electrical connection wires to realize signal input or output.

[0040] The technical solution of this utility model employs a signal terminal module 13, including a first signal terminal 131 and a second signal terminal 132. Signal conduction is achieved through the contact or separation between the first signal terminal 131 and the second signal terminal 132 within the signal terminal module 13. When the signal is conducted, the power supply terminal module 12 is controlled to transmit current. When plugging or unplugging the electrical connector 10, the second signal terminal 132 and the first signal terminal 131 of the signal terminal module 13 can be moved apart before the plugging or unplugging operation, avoiding damage to equipment or personnel caused by hot-plugging.

[0041] In an embodiment of this utility model, the electrical connector 10 further includes a locking module 16, which is movably connected to the base 111. When the locking module 16 rotates relative to the base 111, the locking module 16 drives the second signal terminal 132 to switch between a conducting state and a disconnected state.

[0042] In this embodiment, the latching module 16 extends along the length of the outer shell 11. The latching module 16 moves along the length of the outer shell 11 and drives the connection to the second signal terminal 132, allowing the second signal terminal 132 to switch between a conducting state and a disconnected state. The latching module 16 can be made of insulating material, such as plastic or rubber. The connection between the latching module 16 and the second signal terminal 132 can be achieved by having a clearance opening in the latching module 16, through which the second signal terminal 132 passes. Movement of the clearance opening in the latching module 16 causes the second signal terminal 132 to move along with the latching module 16, switching between a conducting state and a disconnected state. Alternatively, a protrusion can be provided on the latching module 16. Movement of the latching module 16 causes the protrusion to push the second signal terminal 132 from a conducting state to a disconnected state.

[0043] In the embodiments of this utility model, the locking module 16 has a locked state that is fixedly connected to other connectors and an unlocked state that is separated from other connectors. When the locking module 16 switches from the locked state to the unlocked state, it drives the second signal terminal 132 to switch to the disconnected state.

[0044] In this embodiment, the locking module 16 and the base 111 are rotatably or slidably connected. The locking module 16 can move relative to the base 111, thus having a locked state connected to other connectors and an unlocked state separated from other connectors. When the locking module 16 switches from the locked state to the unlocked state, it drives the second signal terminal 132 to switch to the disconnected state before performing the plugging and unplugging operation, thus avoiding damage to equipment or personnel caused by hot plugging and unplugging. Before insertion, the locking module 16 is in the unlocked state and the second signal terminal 132 is in the disconnected state. At this time, the electrical connector 10 is not energized, and the insertion connection has a higher safety factor. After insertion, the locking module 16 switches from the unlocked state to the locked state to make the connection between the electrical connector 10 and the other electrical connector 10 more stable, and the second signal terminal 132 switches to the conducting state, so that the electrical connector 10 is energized. Before unplugging the electrical connector 10, the locking module 16 is switched from the locked state to the unlocked state, and the second signal terminal 132 is switched to the disconnected state to de-energize the electrical connector 10. At this time, unplugging the electrical connector 10 has a higher safety factor.

[0045] In an embodiment of this utility model, the locking module 16 includes two connecting arms 161, a connecting beam 162, and two fastening parts 164. One end of the connecting arm 161 is rotatably connected to a side wall of the base 111, and the other end of the connecting arm 161 is connected to one end of the connecting beam 162. A fastening part 164 is connected to a connection between the connecting beam 162 and the connecting arm 161 and is used for fastening connection with other connectors.

[0046] A connecting rod 163 is provided on the side of the connecting beam 162 facing the base 111. The electrical connector 10 also includes a transmission component 14, which is slidably connected to the base 111. When the locking module 16 switches from the locked state to the unlocked state, the connecting rod 163 pushes the transmission component 14 and drives the second signal terminal 132 to switch to the disconnected state.

[0047] In this embodiment, the locking module 16 is made of metal or rigid plastic. The locking module 16 includes two connecting arms 161, a connecting beam 162, and two engaging parts 164. One end of each connecting arm 161 is rotatably connected to a side wall of the base 111. Both ends of the connecting beam 162 are connected to the other ends of the two connecting arms 161, respectively. An engaging part 164 is located at the connection between the connecting arm 161 and the connecting beam 162, and is used to engage with another electrical connector 10. The various parts of the locking module 16 can be integrally welded together, or they can be made of metal and integrally formed by stamping; no further limitation is made here. A connecting rod 163 is provided on the side of the connecting beam 162 facing the base 111. When the locking module 16 switches from a locked state to an unlocked state, it moves the connecting rod 163, causing the connecting rod 163 to push the transmission component 14 and switch the second signal terminal 132 to a disconnected state, thus de-energizing the electrical connector 10.

[0048] In a preferred embodiment, the locking module 16 further includes two handles, which are respectively disposed on opposite sides of the connecting beam 162, so as to drive the locking module 16 to switch between a locked state and an unlocked state.

[0049] In an embodiment of this utility model, the connecting rod 163 is provided with a first guide slope on the side facing the transmission member 14, the base 111 is provided with a sliding groove 1111, the sliding groove 1111 extends along the direction of contact or distance between the first signal terminal 131 and the second signal terminal 132, and communicates with the second through hole, the transmission member 14 is provided with a second guide slope on the side facing the connecting rod 163, and the transmission member 14 slides through the sliding groove 1111;

[0050] The connecting arm 161 rotates, causing the connecting rod 163 to move, so that the first guide slope pushes the second guide slope and causes the transmission component 14 to press against the second signal terminal 132 to switch to the disconnected state.

[0051] In this embodiment, the connecting rod 163 has a first guide slope on the side facing the transmission member 14, and the transmission member 14 has a second guide slope on the side facing the connecting rod 163. The connecting arm 161 drives the connecting beam 162, which in turn drives the connecting rod 163 to move, causing the first guide slope to move and abut against the second guide slope, pushing the second guide slope and causing the transmission member 14 to move away from the connecting rod 163, thereby causing the second signal terminal 132 to switch to the off state. Through the cooperation between the first guide slope and the second guide slope, the rotation of the connecting rod 163 can be converted into the horizontal movement of the transmission member 14 in the length direction of the housing 11, which in turn causes the second signal terminal 132 to switch from the on state to the off state.

[0052] The base 111 has a groove 1111 that communicates with the second through hole. The groove 1111 is oriented along the length of the outer casing 11, which is the direction in which the second signal terminal 132 and the first signal terminal 131 abut or move away from each other. The transmission member 14 is partially slidably inserted into the groove 1111, which restricts the sliding direction of the transmission member 14 and prevents the movement of the transmission member 14 from deviating. In a preferred embodiment, the groove 1111 is open on one side wall of the outer casing 11, so that the groove 1111 communicates with the outside, and a cover 114 is detachably connected to one side wall of the groove 1111.

[0053] In an embodiment of this utility model, the transmission member 14 includes a first rod and a second rod, the first rod and the second rod are connected at an angle, the first rod is partially slidably disposed in the slide groove 1111, and the first rod is provided with a hook protruding toward the second signal terminal 132. The hook is used to abut against the second signal terminal 132 and drive the second signal terminal 132 to move.

[0054] In this embodiment, the transmission component 14 includes a first rod and a second rod at an angle. The first rod is partially slidably disposed within the slide groove 1111, serving to guide the movement of the transmission component 14. The second rod protrudes outside the slide groove 1111 and is used to abut against the connecting rod 163 to increase the contact surface. A hook is provided on the surface of the first rod facing the second signal terminal 132. When the transmission component 14 moves, the hook moves, causing the second signal terminal 132 to switch from a conducting state to a disconnected state.

[0055] In an embodiment of this utility model, the groove wall of the slide 1111 is provided with a first boss 1111a, and one end of the transmission member 14 is provided with a second boss 141. The second boss 141 can slide between the first boss 1111a and the bottom of the slide 1111.

[0056] In this embodiment, the groove wall of the slide 1111 is provided with a first boss 1111a, and one end of the transmission member 14 is provided with a second boss 141. The second boss 141 can slide between the first boss 1111a and the bottom of the slide 1111, thereby limiting the moving length of the transmission member 14 and preventing the transmission member 14 from leaving the slide 1111.

[0057] In an embodiment of this utility model, the electrical connector 10 further includes an elastic element 15, one end of which is connected to the bottom of the groove 1111, and the other end of which is connected to one end of the transmission element 14.

[0058] In this embodiment, an elastic element 15 is provided between the bottom of the groove 1111 and one end of the transmission member 14. When the transmission member 14 is in the initial state and the second signal terminal 132 is in the conducting state, the elastic element 15 is in the relaxed state. When the locking module 16 switches to the locking state, pushes the transmission member 14 to move, and drives the second signal terminal 132 to switch to the disconnected state, the elastic element 15 is compressed at the same time, the locking module 16 is converted to the unlocked state, the elastic element 15 restores its deformation, pushes the transmission member 14 to move, and drives the second signal terminal 132 or the second signal terminal 132 switches to the conducting state under its own deformation.

[0059] In the embodiments of this utility model, there are multiple first protrusions 112, and the distance between the centers of two adjacent first protrusions 112 is greater than or equal to 16mm and less than or equal to 20mm.

[0060] The distance between the center of the first protrusion 112 near the second protrusion 113 and the center of the second protrusion 113 is greater than or equal to 10 mm and less than or equal to 14 mm.

[0061] In this embodiment, there are multiple first protrusions 112, and correspondingly, there are also multiple power supply terminal modules 12. The distance between the centers of two adjacent first protrusions 112 is greater than or equal to 16mm and less than or equal to 20mm, such as 16mm, 18mm, 20mm or any value within the above range. The distance between the centers of two adjacent first protrusions 112 should not be too large, as this would result in the electrical connector 10 being too long and the overall size being too large. The distance between the centers of two adjacent first protrusions 112 should also not be too small, as this would result in a short creepage path between two adjacent power supply terminal modules 12, which could easily lead to flashover or breakdown problems.

[0062] The distance between the center of the first protrusion 112 near the second protrusion 113 and the center of the second protrusion 113 is greater than or equal to 10 mm and less than or equal to 14 mm, such as 10 mm, 12 mm, 14 mm or any value within the above range. The distance between the center of the second protrusion 113 and the adjacent first protrusion 112 should not be too large, otherwise the width of the electrical connector 10 will be too large and the overall size will be too large. The distance between the center of the second protrusion 113 and the adjacent first protrusion 112 should not be too small, otherwise the creepage path between the two adjacent power supply terminal modules 12 and signal terminal modules 13 will be too short, which will easily cause flashover or breakdown problems.

[0063] Please see Figure 7 and Figure 8 The present invention also proposes a connector assembly 100, which includes an electrical connector 10 and a board-end connector 20 as described above. The board-end connector 20 includes a housing 21, a third terminal module 22 and a fourth terminal module 23. The housing 21 has a first groove 211 and a second groove 212. The third terminal module 22 is disposed in the first groove 211 and the fourth terminal module 23 is disposed in the second groove 212. A first protrusion 112 is inserted into the first groove 211 so that the third terminal module 22 is electrically connected to the power supply terminal module 12. A second protrusion 113 is inserted into the second groove 212 so that the fourth terminal module 23 is electrically connected to the signal terminal module 13.

[0064] In this embodiment, the first protrusion 112 of the electrical connector 10 is inserted into the first groove 211 of the board end connector 20, the power supply terminal module 12 is electrically connected to the third terminal module 22 to realize signal conduction, the second protrusion 113 of the electrical connector 10 is inserted into the second groove 212 of the board end connector 20, and the signal terminal module 13 is electrically connected to the third terminal module 22 to realize current conduction.

[0065] The insertion and removal process of the electrical connector 10 and the board-end connector 20 is as follows: Before insertion, the locking module 16 of the electrical connector 10 is in the unlocked state. The connecting rod 163 of the locking module 16 pushes the transmission member 14 to slide towards the bottom of the slide groove 1111, causing the second signal terminal 132 to switch to the disconnected state and compressing the elastic member 15, so that the electrical connector 10 is inserted into the board-end connector 20 in a de-energized state. After insertion, the locking module 16 is pushed to switch from the unlocked state to the locked state. The latching part 164 of the locking module 16 is engaged with the latching position of the board-end connector 20. The connecting rod 163 of the locking module 16 moves away from and disengages from the transmission member 1111. 4. When the transmission component 14 loses the external force of the connecting rod 163, the elastic element 15 recovers its deformation, pushing the transmission component 14 away from the bottom of the slide groove 1111. The transmission component 14 drives the second signal terminal 132 to switch to the conducting state, making the electrical connector 10 electrically connected to the board end connector 20. When it is necessary to disconnect the electrical connector 10, the locking module 16 is switched to the unlocked state.
