USB female base with built-in mechanical switch

Abstract

The invention discloses a USB female base with a built-in mechanical switch, which comprises a metal shell (1) used for encapsulation and equipped with an front opening, a tongue-shaped fixation base (3) installed inside the metal shell, and a metal pin (4) inlaid in the fixation base, wherein a boss (5) is disposed on the rear part of the fixation base, a groove is disposed in the boss, a switch is inlaid in the groove, a key part (6) of the switch is extruded from inside of the boss to the part above the metal pin, and a front end of a USB plug can trigger the key part in order to trigger the switch when the USB plug is inserted in the USB female base. The USB female base with the built-in mechanical switch disclosed by the invention is small in volume, and can be installed like a common female base. The switch is reliable in work and can be used widely, wherein (1) the switch can be connected into a VCC or a GND of the USB female base in order to realize on-off control of a power source end; (2) as an independent switch, the switch can also be connected into an applicable circuit to realize circuit control; and (3) a circuit with power consumption can be thoroughly disconnected by the switch in order to realize the zero power consumption at a stand-by state.

Description

technical field [0001] The invention relates to a USB port connector, in particular to a USB female seat with a built-in mechanical switch. Background technique [0002] At present, it is very common for various electronic devices to use the standard USB socket (USB-AF) as the interface, especially the USB2.0 socket. The USB2.0 version has four metal pins VCC, D-, D+, and GND. Used to provide power and data transmission, commonly used electronic devices such as mobile phone chargers, mobile power banks (power bank), etc., all use USB2.0 sockets as charging ports. [0003] In practical applications, some electronic devices need to start some control modules synchronously when they are connected to the charger (or other electronic products) through the USB socket, such as the start detection module, the start function module, the stop function module, etc., but the existing USB socket does not With a switch, which brings great inconvenience to the design of the control circui...

Problems solved by technology

This is especially important for some battery-powered devices. In practical applications, some devices are always consuming power when they are in standby (some built-in circuit components, etc.), and often the stored power is exhausted after a period of time. Equipment too numerous to list

The general solution is to set an additional switch. This additional switch not only takes up a limited space on the device or PCB, but also needs to be manually controlled, which is very inconvenient to use. Therefore, the existing USB socket can no longer meet the actual and future demands. Developed applications and needs
