Detailed description of the invention

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the present invention Accompanying drawing in embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that Described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based in the present invention Embodiment, those of ordinary skill in the art obtained under not making creative work premise all its His embodiment, broadly falls into the scope of protection of the invention.

The interface protector that the embodiment of the present invention provides, in the first equipment, described first equipment has Have the exposed contact on its surface, described first equipment utilization its expose contact and be charged or carry out data biography It is defeated, i.e. by the charging wire of the first equipment being exposed contact with the first equipment respectively and power supply is connected, it is achieved It is the first equipment charge, by the data wire of the first equipment being exposed contact with the first equipment respectively and communication sets Standby (such as computer etc.) connect, it is achieved the communication between the first equipment and communication equipment.Wherein, described One equipment can be that any one utilization exposes the equipment that contact is charged or carries out data transmission, specifically Ground, described first equipment is wearable device, but does not limit wearable device.

The interface protector of the embodiment of the present invention is arranged at the first equipment and exposes in contact and the first equipment Between portion's circuit, in actual use, first will be caused to set because exposing the reasons such as contact is dabbled, drench The short circuit of standby power source, and then avoid causing the damage of the first equipment or burning, it is ensured that the peace of the first equipment Full use.Below the embodiment of the present invention is specifically introduced.

Embodiment one

See Fig. 3, for one of schematic diagram of interface protector that the embodiment of the present invention provides, described interface Protection device 3 is built in the first equipment, and described interface protector 3 includes detector unit 31 and connects unit 32, described connection unit 32 respectively with described first equipment expose contact 2, the inside of described first equipment Circuit 4 and described detector unit 31 connect.

Described detector unit 31, for when exposing contact 2 described in external connection 1 is close or connects, to described company Order unit 32 sends and connects signal；When external connection 1 away from or disconnect described in expose contact 2 time, not to described company Order unit 32 sends and connects signal；Described external connection 1 is data wire or the charging wire of described first equipment.

Described connection unit 32, for when receiving the connection signal that described detector unit 31 sends, makes institute State and expose contact 2 and connect with described internal circuit 4；When not receiving the connection letter that described detector unit 31 sends Number time, make described in expose contact 2 and disconnect with described internal circuit 4.

In the embodiment of the present invention one, when by external connection 1 with expose when contact 2 disconnects (when not setting first For when being charged or do not carry out data transmission with the first equipment), or when can't detect external connection 1 In time exposing contact 2 (i.e. when external connection 1 is away from exposing contact 2), utilize connection unit 32 will expose tactile Point 2 separates with internal circuit 4, so in the case of device contact exposes, it is ensured that the first equipment will not be because touching The factors such as point is dabbled, drench cause the mistake short circuit in the first device power source, and then avoid the damage of the first equipment Bad.And by external connection 1 with expose when contact 2 is connected (when the first equipment being charged or with first When equipment carries out data transmission), or when detecting that external connection 1, in time exposing contact 2, utilizes and connects list The contact 2 of exposing of the first equipment 32 is connected by unit with internal circuit 4, to ensure follow-up to be embodied as the first filling apparatus Electricity or the function carried out data transmission with the first equipment.

Embodiment two

The two of the schematic diagram of interface protector shown in Figure 4, on the basis of above-described embodiment one, Described detector unit 31 is specifically as follows magnetic switch 311, and described external connection 1 is magnetic contact external connection.

Described magnetic switch 311, for the Guan Bi when exposing contact 2 described in described external connection 1 is close or connects, And export the signal of telecommunication to described connection unit 32；When described external connection 1 away from or disconnect described in expose contact 2 Time disconnect, do not export the signal of telecommunication to described connection unit 32；The described signal of telecommunication is described connection signal.

Described connection unit 32, for when receiving the connection signal that described magnetic switch 311 sends, makes Described contact 2 of exposing is connected with described internal circuit 4；When not receiving connecing of described magnetic switch 311 transmission During messenger, make described in expose contact 2 and disconnect with described internal circuit 4.

In the embodiment of the present invention two, it is assumed that the first equipment is wearable device.Generally outside wearable device Wiring 1 all contains and is magnetic, and when external connection 1 touches wearable device, can stable absorption set wearable Standby upper, to ensure charging or the integrity of data interaction.

In the embodiment of the present invention two, it is single that interface protector 3 comprises two parts, magnetic switch 311 and connection Unit 32.Magnetic switch 311 is for when there being external connection 1 to come close to or in contact with wearable device, due to external connection 1 containing being magnetic, when it near wearable device or with wearable device expose contact be connected time, magnetic is opened Close 311 Guan Bis, and export the signal of telecommunication to open connection unit 32 so that wearable device exposes on contact 2 Pin can be communicated on wearable device internal circuit 4.Other situation magnetic switch 311 cuts out, such magnetic Switch 311 signal at stop exported down in off position connection unit 32 so that wearable device exposes tactile Pin and wearable device internal circuit 4 on point 2 are isolated.Connect unit 32 to be used for realizing outside wearable device Revealing the pin on contact 2 and the short circuit of wearable device internal circuit 4 or open circuit, the state of short circuit or open circuit takes Certainly in Guan Bi or the disconnection of magnetic switch 311.Visible, only at special magnetic charging wire or magnetic data Line comes close to or in contact with wearable device when exposing contact, and the contact of exposing of wearable device just sets with wearable Standby internal circuit connects.

When magnetic bodies is close or connects interface protector 3, the magnetic switch in interface protector 3 is just Can close, the usual above-mentioned design of some simple demands just meets requirement, but in some strict demands, Also need to increase detection magnetic contact external connection and expose the detection module that contact the most really connects.Specifically See embodiment three to embodiment five.
