Description

Technical Field

[0001] The utility model relates to the technical field of USB interfaces, in particular to a USB connector with an anti-loosening interface. Background Art

[0002] With the development of the electronics industry, more and more electronic products have penetrated into people's daily life and work. USB connectors (such as data cables) as products for interconnection and communication of electronic products have been widely used by electronic product users. USB is the abbreviation of Universal Serial Bus in English. It is an external bus standard used to regulate the connection and communication between computers and external devices. USB is also a technical specification of input and output interfaces. It is widely used in information communication products such as personal computers and mobile devices, and has been extended to other related fields such as photographic equipment, digital TVs (set-top boxes), and game consoles. The latest generation is USB3.1, with a transmission speed of 10Gbit / s, a three-stage voltage of 5V / 12V / 20V, and a maximum power supply of 100W. The new Type C plug-in type is no longer divided into positive and negative. As a high-speed connection standard for computer peripherals, USB has been widely used in various external devices. In order to meet the development requirements of miniaturization and multi-functionality of electronic products, new USB connectors are constantly being launched. USB3.0 uses a new physical interface and new cables to ensure higher-speed connection with new devices. The new interface maintains the same specifications as the 4-wire USB2.0, and adds more lines on the original basis for receiving and transmitting.

[0003] According to the "Anti-loosening Line Connector" disclosed in Chinese Patent Publication No. CN212626331U, the first clamp and the second clamp can wrap and clamp the fixing ring through the provided fixing ring, so as to ensure the connection stability between the male connector and the female connector. The first clamp and the second clamp can be clamped and fixed by the provided first fixing block, the second fixing block, the connecting rod, the connecting block, the spring and the clamping block.

[0004] However, the above device has the problem that when used for a long time, the socket connected thereto will generate a lot of dust and other stains, which will affect the service life of the connector. Utility Model Content

[0005] The utility model aims to provide a USB connector with an anti-loosening interface to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a USB connector with an anti-loosening interface, comprising a main body structure and an anti-loosening structure, wherein the outer wall of the main body structure is fixedly connected with the anti-loosening structure;

[0007] The main structure includes a connector shell, a USB slot is arranged on the outer wall of the connector shell, sliding grooves are opened on the outer walls on both sides of the connector shell, a sliding block is slidingly arranged inside the sliding groove, and a dust cover is fixedly connected to one end of the sliding block away from the sliding groove.

[0008] Preferably, a fixing groove is provided on the outer wall of the connector housing, a fixing block is provided inside the fixing groove, and the top of the fixing block is semicircular.

[0009] Preferably, a return spring is fixedly connected to the inner bottom wall of the fixing groove, and the top of the return spring is fixedly connected to the bottom of the fixing block.

[0010] Preferably, a positioning groove is provided on the inner wall of the dust cover, and the shape and size of the positioning groove are matched with the shape and size of the fixing groove.

[0011] Preferably, the anti-slip structure comprises a fixing frame, a sliding rod is arranged on the top of the fixing frame, an extrusion block is fixed on the top of the sliding rod, and a limiting plate is fixedly connected to the bottom of the sliding rod.

[0012] Preferably, the bottom of the sliding rod passes through the outer wall of the fixing frame and extends into the inside of the fixing frame, and the sliding rod is slidably connected to the fixing frame.

[0013] Preferably, damping pads are provided on the inner wall of the fixing frame and the bottom of the limiting plate.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model pulls the dust cover so that the sliding block drives the dust cover to move toward the USB slot through the sliding groove. When the positioning groove on the dust cover is aligned with the fixing groove on the connector housing, the reset spring exerts an outward force on the fixing block to make the fixing block disengage from the fixing groove and snap into the positioning groove, thereby completing the fixing of the dust cover, so that the dust cover shields the USB slot from dust, thereby preventing dust from being generated at the connection port of the connector and affecting its service life.

[0016] Second, when the utility model connects the male socket to the female socket in the connector housing through the USB slot in the fixing frame, when the dust cover is pulled to protect the socket from dust, the dust cover squeezes the extrusion block at the same time, so that the extrusion block moves downward through the sliding rod and drives the limit plate to move downward at the same time. The limit plate that moves downward squeezes and fixes the male socket, thereby fixing the USB interface body and preventing the USB interface body from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
