Description

Technical Field

[0001] The utility model relates to the technical field of USB connectors, in particular to a USB connector with a self-protection structure. Background Art

[0002] The USB connector is a common connector used to connect USB devices. It is an external bus standard that regulates the connection and communication between computers and external devices. The USB interface has a hot-swappable function and can connect to a variety of peripherals, such as USB flash drives, mice, keyboards, etc.

[0003] The existing USB connector has no protection function. When the USB connector is not in use, the USB metal interface is directly exposed to the outside, which makes the USB metal interface easy to be damaged. For example, a USB data connector disclosed in application number CN200920000956.6 does not have a protection structure. The plug-in terminal is directly exposed to the outside and is easily damaged by external factors, such as dust, dirt, scratches, etc. These factors may cause poor contact or damage to the plug-in terminal, affect its normal operation, and reduce the service life of the USB connector.

[0004] Therefore, it is necessary to invent a USB connector with a built-in protective structure to solve the above problems. Summary of the invention

[0007] Preferably, a connector terminal is fixedly installed inside the USB metal interface, and the USB metal interface is arranged inside the second shell, so that the second shell can protect the USB metal interface.

[0008] Preferably, the first shell and the second shell are slidably connected, and a groove is provided at the contact position between the first shell and the second shell, so that the second shell can be slidably retracted inside the groove of the first shell.

[0009] Preferably, the slider is designed in a semicircular structure, 6 sliders are provided, and the slider and the slide groove are slidably connected, so that the No. 2 shell can slide through the slider and the slide groove, and the No. 1 shell can be tightly combined with the No. 2 shell, thereby improving the sealing performance.

[0010] Preferably, a buckle cover is provided at one end of the No. 2 shell, and hinges are installed on the top of the No. 2 shell and the buckle cover. The No. 2 shell and the buckle cover are hingedly connected so that the buckle cover can be flipped open or closed.

[0011] Preferably, two positioning plates are provided, and the positioning plates are hingedly connected to the mounting plate, and the two positioning plates are centrally symmetrical with respect to the No. 1 housing, so that the positioning plates can be rotated and adjusted on the mounting plate.

[0012] Preferably, a fixing bolt is connected through the positioning plate, and the fixing bolt is threadedly connected to the positioning plate, so that the fixing bolt can be screwed on the positioning plate but will not come off.

[0013] Preferably, a No. 1 screw hole and a No. 2 screw hole are provided at the contact position between the fixing bolt and the No. 2 shell, and two of the No. 1 screw hole and the No. 2 screw hole are provided, and the outer wall thread of the fixing bolt cooperates with the inner wall threads of the No. 1 screw hole and the No. 2 screw hole, so that when the fixing bolt is connected to the No. 1 screw hole, the state of the No. 2 shell accommodating the USB metal interface can be fixed, and when the fixing bolt is connected to the No. 2 screw hole, the state of the No. 2 shell exposing the USB metal interface can be fixed.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] Through the arrangement of the No. 1 shell and the No. 2 shell, the No. 1 shell, the No. 2 shell and the buckle cover form a sealing structure, so the connector body can be stored inside the No. 1 shell and the No. 2 shell when not in use, thereby protecting the USB metal interface from dust, dirt and other impurities, which helps to keep the USB metal interface clean and prevent poor contact or damage caused by dust and dirt. The connector body with the protective structure is easier to carry and store, which can reduce the friction and collision between the USB metal interface and other objects, protect the USB metal interface from damage, and enhance its service life.
