Between, in actual use, the short circuit in the first device power source caused by the reasons such as will not be splashed, be drenched because of exposed contact, into
And avoid the damage of the first equipment or burn, it ensure that the safe handling of the first equipment.Below with regard to the embodiment of the present invention into
Row is specific to be introduced.
Embodiment one
It is one of the schematic diagram of interface protector provided in an embodiment of the present invention, the interface protector referring to Fig. 3
3 are built in the first equipment, and the interface protector 3 includes detection unit 31 and connection unit 32, the connection unit 32
It is connect respectively with the exposed contact 2 of first equipment, the internal circuit 4 of first equipment and the detection unit 31.
The detection unit 31 is used for when external connection 1 is close or connects the exposed contact 2, Xiang Suoshu connection unit
32 send connection signal；When external connection 1 is separate or disconnects the exposed contact 2, does not send and connect to the connection unit 32
Signal；The external connection 1 is the data line or charging cable of first equipment.
The connection unit 32, for making described exposed when receiving the connection signal that the detection unit 31 issues
Contact 2 and the internal circuit 4 are connected；When not receiving the connection signal that the detection unit 31 is sent, make described exposed
Contact 2 and the internal circuit 4 disconnect.
In the embodiment of the present invention one, (the first equipment ought not be carried out when disconnecting external connection 1 and exposed contact 2
When charging or not carrying out data transmission with the first equipment), or (work as when can't detect external connection 1 close to exposed contact 2
External connection 1 is far from exposed contact 2) when, exposed contact 2 is separated with internal circuit 4 using connection unit 32, is touched in this way in equipment
In the case that point is exposed, the mistake in the first device power source caused by the factors such as the first equipment of guarantee will not be splashed, be drenched because of contact
Short circuit, and then avoid the damage of the first equipment.And it (is carried out when to the first equipment when external connection 1 to be connect with exposed contact 2
When charging or carrying out data transmission with the first equipment), or when detecting external connection 1 close to exposed contact 2, utilize connection
The exposed contact 2 of first equipment is connect by unit 32 with internal circuit 4, to guarantee subsequent to be embodied as the first equipment charge or with
The function that one equipment carries out data transmission.
