Description

Technical Field

[0001] The utility model relates to an electric connector, in particular to an electric connector with high detection sensitivity and better safety performance protection. Background Art

[0002] Among the types of electrical connectors commonly used in various electronic products, the connectors with Universal Serial Bus (USB) specifications are the most widely used. With the advancement of technology, there are more and more types of USB, such as USB 2.0, USB 3.0, Micro USB, Mini USB or USB TYPE-C. Among them, USB TYPE-C connectors have been widely used in various electronic products.

[0003] However, when people use various electronic products, they often accidentally come into contact with water or other liquids, causing water or liquids to adhere to the electrical connectors of the electronic products. In addition, they are often charged when they are not completely dry, which aggravates the corrosion of the copper material of the electrical connectors and causes dangers in use.

[0004] Chinese Patent Publication No. 214673264 discloses "an electrical connector", including an insulating body, wherein at least one opening is provided on the surface of the insulating body; an intermediate piece is arranged in the insulating body; a side piece is arranged in the insulating body, the side piece is relatively arranged on the side of the intermediate piece and is separated from the intermediate piece, the intermediate piece is provided with an intermediate piece corresponding side, the side piece is provided with a side piece corresponding side, the intermediate piece corresponding side and the side piece corresponding side correspond to each other in the opening of the insulating body, and are connected to the outside of the insulating body through the opening; and a plurality of terminals are arranged in the insulating body.

[0005] However, the above-mentioned electrical connector is designed for serious water ingress conditions such as falling into water. Electrical conduction will only be achieved when water enters the opening and the middle piece contacts the water. The above-mentioned electrical connector has low detection sensitivity. In the case of water repellent or less water, water will only adhere to the surface of the insulating body and will not enter the opening. Therefore, the middle piece will not be conductive if it does not contact the water, causing the electrical connector to continue to operate in the presence of water.

[0006] Therefore, it is necessary to provide an electrical connector with high detection sensitivity and better safety protection. Utility Model Content

In the left-right direction of the insulating body 1, the retaining portion 91 of the detection terminal 9 is aligned with the fixing portions 213 of the plurality of terminals 211.

[0044] Since the detection portion 92 of the detection terminal 9 has a larger width than the terminals 211, the signal terminal 2112 located on the left side of the detection terminal 9 has a first bending structure 23, and the first bending structure 23 is used to avoid the left side of the detection portion 92. The power terminal 2111 located on the right side of the detection terminal 9 has a second bending structure 24, and the second bending structure 24 is used to avoid the right side of the detection portion 92.

The width of the notch 217 of the signal terminal 2112 adjacent to the detection terminal 9 is greater than the distance between two adjacent signal terminals 2112. In a specific implementation, the distance between the notch 217 of the signal terminal 2112 and the left rear oblique edge 923 of the detection terminal 9 may also be equal to the distance between the power terminal 2111 and the detection portion 92 of the detection terminal 9. The width of the notch 217 of the signal terminal 2112 adjacent to the detection terminal 9 may also be equal to the distance between two adjacent signal terminals 2112.

[0058] As mentioned above, the electrical connector 100 of the present invention has an innovative structural design, and the two detection terminals 9 are respectively arranged on the inner sides of the two power terminals 2111, and the detection portion 92 of the detection terminal 9 is in the shape of a pebble, which increases the detection area and improves the detection effect. When water flows to the electrical connector 100 of the present invention, the capacitance of the electrical connector 100 of the present invention increases. When the detection terminal 9 detects that the capacitance of the electrical connector 100 of the present invention has changed, the electrical connector 100 of the present invention stops charging or transmitting signals to protect the electrical connector 100 of the present invention from stopping working in the presence of water. Therefore, the electrical connector 100 of the present invention has high detection sensitivity and better safety performance to protect the electrical connector itself and the user.
