Description

Technical Field

[0001] The utility model relates to the technical field of data connectors, in particular to a high-speed plug connector with stable transmission in a high-frequency band. Background Art

[0002] The plug connector is suitable for realizing the butt joint between data lines, and further realizing the transmission of high-frequency signals between two devices. After retrieval, the patent with the authorization number of CN214542810U in China discloses a plug connector for realizing four-channel high-frequency signal transmission. Although the male plug of this plug connector will not retreat when encountering external pulling force, ensuring the electrical connection between the four-channel pins and the four-channel pin holes, so as to realize stable high-frequency signal transmission, when this plug connector is disconnected without use, since the slot at one end of the female head is in an open state, external dust will enter the slot inside the female head end, resulting in a large amount of dust accumulating in the slot at the female head end. And because there are pins inside the female head, it is not convenient to clean the dust inside the female head, which will cause the male plug not to be inserted in place due to too much dust, thus affecting the connection stability of the connector. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a high-speed plug connector with stable transmission in a high-frequency band, which solves the problem that external dust will enter the female head when the existing plug is not in use, resulting in too much dust inside the female head and affecting the butt joint of the male plug as mentioned in the background art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A high-speed plug connector with stable transmission in a high-frequency band includes a female head, a docking head, a clamping plate and a clamping block. A docking head is arranged at one end of the female head. The docking head is used to dock with a male plug. The male plug penetrates inside the docking head. Pins are arranged inside the docking head. The pins are docked with the hole grooves on the surface of one end of the male plug. Data lines are connected to both the male plug and the other end of the female head. One end of the top of the female head is rotatably connected to one end of the clamping plate through a connecting shaft. A coil spring is sleeved outside the connecting shaft. The coil spring is used to close the clamping plate.

[0005] Preferably, the inner surface of one end of the docking head is in an arc chamfer structure, and the inner wall of the docking head is closely attached to the surface of the male plug, and the edge of one end of the male plug is in an arc chamfer shape, which is beneficial to expanding the insertion port at one end of the docking head, facilitating the docking and insertion of the male plug. When the male plug is inserted, it will align with the pins along the arc chamfer structure.

[0006] Preferably, a dial is adhesively connected to the top of the clamping plate. The surface of the dial is in a concave-convex structure, and rubber coatings are provided on the surface of the dial and the surface of the clamping plate. The rubber coatings are beneficial to improving the tightness between the clamping plate and the docking head, and further beneficial to improving the dust-proof effect.

[0007] Preferably, a raised blocking block is provided on the inner surface of the bottom of the card plate, and the blocking block is connected to the limit block by rotating the card plate. The limit block is provided on the top surface of the male head. Under the action of the coil spring, one end of the bottom of the card plate can be pressed against the top surface of the male head, so that the blocking block on the surface of the card plate can be engaged with the limit block on the top of the male head.

[0008] Preferably, the clamping block is wedge-shaped, and one side surface of the limiting block is inclined, and the inclined surface of one side of the limiting block fits with the slope of one side of the clamping block, which is beneficial to improve the firmness of the clamping block and the limiting block.

[0009] The utility model provides a high-speed plug connector with stable transmission in high frequency band, which has the following beneficial effects:

[0010] (1) A high-frequency band stable transmission high-speed plug connector. When in use, the paddle is pushed backward to open the card plate at one end of the connector, thereby exposing the slot at the female end, so that the male end can be plugged in for connection. When the connector is not in use, after the male end is unplugged, the card plate will rotate through the top shaft under the action of the coil spring, so that the card plate can be automatically closed, so that the card plate can cover the hole slot at one end of the connector, thereby achieving a dust-proof effect and preventing external dust from entering the female end when the connector is not in use.

[0011] (2) This high-frequency band stable transmission high-speed plug connector, when the card plate is opened and the male head is inserted into the female head, the paddle is released, so that the card plate can press one end of the bottom of the card plate against the top surface of the male head under the action of the coil spring, and then the card block on the card plate surface can be engaged with the limit block on the top of the male head, so that the male head will not fall out of the female head when pulled by external force, which is beneficial to improve the firmness of the connection.

[0012] This solves the problem that external dust enters the female head when the existing plug is not in use, causing a lot of dust inside the female head and affecting the docking of the male head. BRIEF DESCRIPTION OF THE DRAWINGS
