Description

Technical Field

[0001] The present invention relates to the field of electrical devices, and in particular to a DP connector. Background Art

[0002] The DP connector is mainly used to connect video sources to devices such as displays, supports video output up to 8K resolution, and supports the transmission of audio signals. By using the DP connector, users can transfer digital materials and content to third-party devices while maintaining high resolution (up to 8K).

[0003] The existing Chinese patent with publication number CN111682371B discloses an aviation connector that complies with the standard HDMI and DP signal definitions. It is a plug self-locking connector structure. The connector includes a male head and a female head. The male head's pin is installed in a circular male head installation cavity. The female head is correspondingly provided with a jack. The male head has 20 pins, which are evenly distributed in the male head installation cavity. There are a total of four groups of high-speed differential pairs with ground wires and eight single ends. Each group of high-speed differential pairs contains two signal lines and one ground wire. The signal lines are distributed near the circumferential edge of the male head installation cavity, and the ground wire is set at a position close to the center of the male head installation cavity. The two signal lines are connected, and the insulator between the signal lines is provided with dumbbell-shaped air compensation. The ground wire and the two signal lines are triangular, and the ground wire and the two signal lines are isolated by an insulator.

[0004] The above patent does not use a flip fastener to assist in connection and fixation after the terminals are connected, which is a defect; however, some other existing DP connectors currently use a flip fastener to achieve locking after the terminals are connected, but it still has defects. For example, during the flipping process of the flip fastener, it often cannot be effectively restricted due to the large swing angle, and may be rotated to various angles to achieve locking, affecting the locking. Summary of the invention

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a DP connector to solve the problems mentioned in the background technology that the connection is easy to loosen and the flip fastener is difficult to control the angle.
