[0038] [First Embodiment]

[0039] Please see Figures 1 to 3 The present invention provides an electrical connection device that conforms to the Type C specification and can be applied to plug electrical connectors or socket electrical connectors. This embodiment discloses a plug electrical connector. The electrical connection device includes a base 1, a terminal group 2, a circuit board 3, a switch unit 4, a housing 5, and a gripper 6.

[0040] The base 1 is made of insulating material such as plastic. The terminal group 2 is disposed on the base 1. The terminal group 2 can be disposed inside or outside the base 1. In this embodiment, the base 1 is a hollow body, so that the terminal group 2 can be disposed inside the base 1.

[0041] The terminal group 2 includes multiple terminals 21 made of a highly conductive metal. The terminals 21 can be arranged in two rows, top and bottom, and can be located on the top and bottom sides inside the base 1. One end of each terminal 21 can extend out of the base 1 and be electrically connected to the circuit board 3. A metal shell 7 can also be provided on the outside of the base 1 to protect the base 1 and the terminal group 2 and to provide electromagnetic shielding. The circuit board 3 can also be electrically connected to a transmission line 9.

[0042] The circuit board 3 is located behind the base 1 and is electrically connected to the plurality of terminals 21. The switch unit 4 may be located on the circuit board 3 and is electrically connected to the circuit board 3. The structure of the switch unit 4 is not limited, and the switch unit 4 may be a micro switch, spring contact, spring pin, or sensor, or other various switch components.

[0043] The outer shell 5 is made of insulating material such as plastic and covers the base 1 and the circuit board 3. One end (front end) of the base 1 and the metal shell 7 can extend out of the outer shell 5, so that the base 1 and the terminal group 2 can be plugged into the docking connection device 100 to achieve electrical connection.

[0044] The gripper 6 is made of insulating material such as plastic and is a hollow shell, which can be a one-piece structure. The gripper 6 has an actuating part 61, which can be located at a lower horizontal height. The gripper 6 is fitted onto the outside of the outer shell 5 and can move on the outer shell 5, that is, it can move along an insertion direction A and a withdrawal direction B. The insertion direction A is the direction in which the electrical connection device engages with the mating connection device 100, and the withdrawal direction B is the direction in which the electrical connection device separates from the mating connection device 100. The insertion direction A and the withdrawal direction B are opposite directions. The gripper 6 is fitted onto the outside of the outer shell 5, and there is a predetermined tightness between the outer shell 5 and the gripper 6, so that the gripper 6 can be properly positioned on the outer shell 5, allowing the gripper 6 to drive the entire electrical connection device to perform insertion and withdrawal actions. The outer shell 5 and the gripper 6 are not limited to being made of plastic; for example, they can also be made of metal or other materials.

[0045] When the grip 6 moves along the insertion direction A and the withdrawal direction B, it can be used to control the switch unit 4, causing the switch unit 4 to open or close. Specifically, the user can hold the grip 6 to perform insertion and removal operations on the electrical connection device. When the user holds the electrical connection device, the grip 6 can be used to drive the electrical connection device to insert with the docking connection device 100. When the electrical connection device is inserted with the docking connection device 100, due to the predetermined tightness between the housing 5 and the grip 6, the grip 6 will not move relative to the housing 5, but the grip 6 can move together with the housing 5. When the electrical connection device is inserted into the docking connection device 100 in a position (e.g. Figure 2 As shown), that is, when the electrical connection device and the docking connection device 100 are fully connected, the housing 5 is stopped and positioned when it touches the front end of the docking connection device 100. Only then will the gripping member 6 begin to move relative to the housing 5, and the gripping member 6 continues to move along the connection direction A (as shown). Figure 3 As shown, the actuating part 61 of the gripper 6 actuates the switch unit 4, causing the switch unit 4 to open, at which point the electrical connection device is energized and transmits power. Since the electrical connection device and the mating connection device 100 only begin to transmit power after the insertion is completed, arc discharge can be effectively avoided.

[0046] When the user holds the electrical connection device, the grip 6 can also be used to separate the electrical connection device from the docking connection device 100. When the electrical connection device and the docking connection device 100 are separated, due to the certain tightness between them, the docking connection device 100 can temporarily position the base 1 and the outer shell 5, allowing the grip 6 to move relative to the outer shell 5. The grip 6 can move along the pull-out direction B (e.g., Figure 2 As shown, the actuating part 61 of the gripper 6 is moved away from the switch unit 4, causing the switch unit 4 to close. At this time, the electrical connection device will not conduct power transmission, and the gripper 6 continues to move along the pull-out direction B, so as to drive the electrical connection device and the docking connection device 100 to separate. Since the electrical connection device and the docking connection device 100 are de-energized before separation, the phenomenon of arc discharge can be effectively avoided.

[0047] [Second Embodiment]

[0048] Please see Figure 4 and Figure 5 In this embodiment, the circuit board 3 can also be electrically connected to a light-emitting component 8, which can be a light-emitting diode or a light bulb, etc. The housing 5 and the grip 6 can also be light-transmitting, or have a light-transmitting portion 62 corresponding to the light-emitting component 8, so that the light emitted by the light-emitting component 8 can be emitted outwards. When the switching unit 4 is activated (turned on), (e.g.) Figure 5As shown, the light-emitting component 8 emits light outward to create a light display effect, informing the user that the electrical connection device is in a conductive state. Additionally, a front positioning part 51 and a rear positioning part 52 can be provided on the housing 5. When the gripper 6 moves along the insertion direction A to a predetermined position, the gripper 6 can abut against the front positioning part 51 and be positioned. When the gripper 6 moves along the withdrawal direction B to another predetermined position, the gripper 6 can abut against the rear positioning part 52 and be positioned.

[0049] [Third Embodiment]

[0050] Please see Figure 6 In this embodiment, the switching unit 4 may include a touch switch 41 and an electronic switch 42. The electronic switch 42 may be a metal-oxide-semiconductor (MOS) switching circuit. The touch switch 41 and the electronic switch 42 are connected and electrically connected between two terminals 21, which serve as a power supply terminal and a ground terminal, respectively. When the gripper 6 moves along the insertion direction A and the withdrawal direction B, it can be used to press or release the touch switch 41 of the switching unit 4 to drive the electronic switch 42 to perform a switching action, thereby opening or closing the switching unit 4.

[0051] [Fourth Embodiment]

[0052] Please see Figure 7 In this embodiment, the gripper 6 may also be provided with a front protrusion 63 and a rear protrusion 64. When the gripper 6 moves to a predetermined position along the insertion direction A, the front protrusion 63 of the gripper 6 can abut against the outer shell 5 and be positioned. When the gripper 6 moves to another predetermined position along the pull-out direction B, the rear protrusion 64 of the gripper 6 can abut against the outer shell 5 and be positioned.

[0053] [Fifth Embodiment]

[0054] Please see Figure 8 In this embodiment, the switch unit 4 can also be placed on the terminal 21 of the terminal group 2. That is, the terminal 21 can be extended to form a touch switch 41, so that the switch unit 4 is electrically connected to the circuit board 3, which can simplify the overall structure and reduce costs.

[0055] [Sixth Embodiment]

[0056] Please see Figure 9 and Figure 10 In this embodiment, an elastic member 10 can also be provided between the grip 6 and the outer shell 5. The elastic member 10 can push the grip 6 to move along the insertion direction A, so that the touch part 61 of the grip 6 touches the switch unit 4, so that the switch unit 4 is turned on, and the electrical connection device can conduct power transmission when the user lets go.

[0057] [Seventh Embodiment]

[0058] Please see Figure 11 In this embodiment, the switch unit 4 can also be a slide switch, and the grip 6 can be used to touch and push the switch unit 4 to control the switch unit 4 to open and close.

[0059] [Eighth Embodiment]

[0060] Please see Figure 12 In this embodiment, the circuit board 3 in the above embodiment is omitted. The electrical connection device in this embodiment includes a base 1, a terminal group 2, a switch unit 4, a housing 5, and a gripper 6. The terminal group 2 is mounted on the base 1, the switch unit 4 is electrically connected to the terminal group 2, the housing 5 covers the base 1, and the gripper 6 is a hollow housing with an actuating part 61 that can actuate the switch unit 4. The gripper 6 is sleeved on the outside of the housing 5 and can move on the housing 5 along the insertion direction A and the withdrawal direction B, which are opposite directions. When the gripper 6 moves along the insertion direction A and the withdrawal direction B, it can control the switch unit 4 to open and close, so that when the electrical connection device is inserted into the docking connection device 100, it is fully inserted before conduction, and the power is cut off before being pulled out.

[0061] [Ninth Embodiment]

[0062] Please see Figure 13 In this embodiment, a touch-sensitive switch 20 can also be provided on the grip 6. The touch-sensitive switch 20 is electrically connected to the circuit board 3. The user can use the touch-sensitive switch 20 to control the conduction and disconnection of the electrical connection device. The device is turned on immediately after the hand touches and leaves the touch-sensitive switch 20. In another embodiment, the grip 6 can also be made fixed, so that the grip 6 is fixed to the outside of the housing 5. The opening and closing can be controlled entirely by the touch-sensitive switch 20. When the electrical connection device is plugged in and unplugged from the docking connection device, the touch-sensitive switch 20 can be used to control the connection. The device is turned on only when fully inserted, and the power is turned off before being pulled out.

[0063] [Tenth Embodiment]

[0064] Please see Figures 14 to 17In this embodiment, the terminal group 2 includes multiple terminals 21, which are made of a metal material with good conductivity. Each terminal 21 includes a first segment 211, a second segment 212, and a third segment 213. The first segment 211 and the second segment 212 are connected by a zigzag line 214. The length of the second segment 212 is less than the length of the first segment 211. The second segment 212 and the third segment 213 are spaced apart and located on a straight line. The first segment 211 and the second segment 212 can be bent along the zigzag line 214, so that a portion of the first segment 211 overlaps the second segment 212. The portion of the first segment 211 not overlapping the second segment 212 is bent to form an elastic arm 215 (e.g., ...). Figure 14 and Figure 15 As shown, the elastic arm 215 is located above the third segment 213, thus forming the switch unit 4. The actuating part 61 of the gripper 6 can actuate the elastic arm 215 of the switch unit 4, causing the elastic arm 215 to contact the third segment 213 and become conductive. The actuating part 61 of the gripper 6 can also disengage from the elastic arm 215 of the switch unit 4, causing the elastic arm 215 to detach from the third segment 213 and become disconnected. A reset elastic member 216 can also be provided below the elastic arm 215. The reset elastic member 216 can push the elastic arm 215 upward to provide elasticity for the elastic arm 215 to reset.

[0065] The actuating part 61 of the gripper 6 can be used to actuate the switch unit 4. When the gripper 6 moves along the insertion direction and the withdrawal direction, it can be used to control the switch unit 4 to open and close, so that when the electrical connection device and the docking connection device are inserted or removed, the connection is made only when fully inserted, and the power is cut off before being pulled out.

[0066] [Beneficial Effects of the Examples]

The switching unit is electrically connected to the circuit board. The housing covers the base and the circuit board. The gripper is a hollow shell with an actuating part that can actuate the switching unit. The gripper is sleeved on the outside of the housing and can move along the insertion and removal directions on the housing. When the gripper moves along the insertion and removal directions, it can control the opening and closing of the switching unit. This ensures that when the electrical connection device is inserted into or removed from the mating connection device, it is fully inserted before conduction, and de-energized before removal. Therefore, when the electrical connection device is inserted into or removed from the mating connection device, no arc discharge occurs between the terminals and other components, effectively protecting the internal components of the system.

The gripper is sleeved on the outside of the shell and can move on the shell along an insertion direction and an extraction direction, which are opposite directions. When the gripper moves along the insertion direction and the extraction direction, it can control the switch unit to open and close, so that when the electrical connection device is inserted into and removed from a mating connection device, it is fully inserted before conduction, and the power is cut off before removal. The terminal group includes multiple terminals, one of which includes a first segment, a second segment, and a third segment. The first segment and the second segment are connected by a zigzag line, and the second segment and the third segment are spaced apart. The second segment and the third segment are located on a straight line. The first segment and the second segment can be bent along the zigzag line so that a portion of the first segment overlaps the second segment. The portion of the first segment that is not overlapped with the second segment is bent to form an elastic arm. The elastic arm is located above the third segment, thus forming the switching unit.
