Interface protection device and protection method

Abstract

The invention discloses an interface protection device. The interface protection device is arranged in a first device and comprises a detection unit and a connection unit, wherein the connection unit is connected with an exposed contact of the first device, an internal circuit of the first device and the detection unit, the detection unit is used for sending a connection signal to the connection unit when an external wire gets close to or is connected with the exposed contact and is not used for sending the connection signal to the connection unit when the external wire deviates from or is disconnected with the exposed contact, the external wire is a data line or a charging line of the first device, and the connection unit is used for making the exposed contact and the internal circuit connected when the connection signal sent by the detection unit is received and making the exposed contact and the internal circuit disconnected when the connection signal sent by the detection unit is not received. The invention also discloses an interface protection method.

Description

technical field [0001] The invention relates to the field of interface technology, in particular to an interface protection device and a protection method. Background technique [0002] A wearable device refers to a portable device that can be directly worn on the body or integrated into the user's clothes or accessories, such as a wrist-supported watch device (including products such as watches and wristbands). [0003] Current wearable devices, due to limited size, mostly use contact interface design. Such interfaces are mostly used to charge wearable devices, communicate with computers to exchange data, or update firmware and download programs when the device leaves the factory. Wait. [0004] see figure 1 One of the schematic diagrams of the contact-type wearable device is shown. Since the contacts of the wearable device are directly exposed on the surface of the device, the contacts are splashed with water, wet, etc., which will cause a short circuit of the power supp...

Problems solved by technology

[0004] see figure 1 One of the schematic diagrams of the contact-type wearable device is shown. Since the contacts of the wearable device are directly exposed on the surface of the device, the contacts are splashed with water, wet, etc., which will cause a short circuit of the power supply on the wearable device, thereby causing Damage to wearables

In this regard, the commonly used protection or waterproof design is usually to add a rubber plug (see figure 2 The schematic diagram of the contact wearable device shown in the second), when charging the wearable device or exchanging data with the wearable device through the device contact, the rubber plug does not block the device contact, in other cases, the rubber plug is used to block live device contacts, however, figure 2 The design shown will not only increase the production cost and workload, but the cumbersome operation of inserting and pulling out the rubber plug and using the rubber plug to block the contacts for a long time will also make the rubber plug easy to fall off
