Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] The invention discloses a usb hub, as shown in Fig. 1 to Figure 4 As shown, it includes a housing and a circuit board 3 fixed in the housing and provided with at least two usb interfaces 31 , and a light emitting module for emitting light is also provided on the circuit board 3 . In the present invention, since the circuit board 3 of the usb hub is provided with a light-emitting module for lighting, the usb hub is powered on, and the light-emitting module emits light, thereby showing the working state of the usb hub; once the usb hub breaks down, the light-emitting module does not emit light; and when used When the usb hub is connected with the device, the light emitting module emits light, which is convenient for use.

[0023] As shown in Figure 1, the casing includes a front casing 1 and a rear casing 2, combined figure 2 and Fig...

Abstract

The invention discloses a usb (Universal Serial Bus) concentrator which comprises a shell and a circuit board, wherein the circuit board is fixed in the shell and is provided with at least two usb interfaces; the circuit board is also provided with a light emitting module for emitting light. According to the invention, the circuit board of the usb concentrator is provided with the light emitting module for emitting light, and thus, when the usb concentrator is powered on, the light emitting module emits light so as to display the working state of the usb concentrator; once the usb concentrator goes wrong, the light emitting module does not emit light; when the usb concentrator is connected with equipment, the light emitting module emits light, so that the usb concentrator is convenient to use.

Description

technical field [0001] The invention relates to the field of household electrical appliances, and more specifically relates to a usb hub. Background technique [0002] There are more and more usb devices, such as: U disk, MP3, MP4, MP5, usb lights, usb speakers, etc., and most of the mobile phones used by people now use usb data cables to connect or charge computers. More and more, the usb interface on the computer can no longer meet people's needs. [0003] I have designed a usb hub, which includes a housing and a circuit board fixed in the housing. The circuit board is provided with at least two usb interfaces. This program is unpublished. Once the usb hub fails during use, it is not easy to find. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a usb hub with light emitting function. [0005] The object of the present invention is achieved through the following technical solutions: a usb hub, comprising a h...
