[0031] [First Embodiment]

[0032] Please see Figures 1 to 3 This utility model provides an electrical connection device that conforms to the Type C standard 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.

[0033] 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.

[0034] The terminal group 2 includes multiple terminals 21, which are made of a highly conductive metal material. The terminals 21 can be arranged in two rows, 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.

[0035] 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 disposed 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.

[0036] 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.

[0037] The gripper 6 is made of insulating material such as plastic and is a hollow shell. The gripper 6 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 sleeved on the outside of the outer shell 5 and can move on the outer shell 5. That is, the gripper 6 can move on the outer shell 5 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 sleeved on 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.

[0038] 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 2As 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.

[0039] 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.

[0041] 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 5 As 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.

[0042] [Third Embodiment]

[0043] Please see Figure 6In 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.

[0044] [Fourth Embodiment]

[0045] 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.

[0046] [Fifth Embodiment]

[0047] 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.

[0048] [Sixth Embodiment]

[0049] 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.

[0050] [Seventh Embodiment]

[0051] 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.

[0052] [Eighth Embodiment]

[0053] Please see Figure 12In 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 mating connection device, it is fully inserted before conduction, and the power is cut off before being pulled out.
