To ground terminal.In this way, when contact signal output end pin3 is not electrically connected with host equipment 2, the detecting of first processing units 11 is believed
The first signal M that number input terminal 112 detects, when contact signal output end pin3 is electrically connected with host equipment 2, the first processing
The detection signal input terminal 112 of unit 11 detects second signal N, and in this implementation, the first signal M is low level signal, the
Binary signal N is high level signal.
When implementing, the second signal interconnecting piece 22 of host equipment 2 has the ground connection of contact signal input end pin3 and second
Pin1 is held, contact signal input end pin3 electrical connection levels voltage input unit 23, the second ground terminal pin1 is used to connect ground terminal,
Also that is, relative to conventional signal interconnecting piece, the socket end that the ends pin2 shown in Fig. 3 b can be used for connecting power supply is omitted, on
All statements with the second signal interconnecting piece 22 are stated to refer both to connect with the contact signal input end pin3 of the second signal interconnecting piece 22,
Also that is, the signal input end 211 and level voltage input unit 23 of contact signal input end pin3 coupling second processings unit 21.
Level voltage input unit 23 has the first level voltage input end and first resistor R1, the first level voltage input end
The first level voltage vcc is provided, one end of first resistor R1 is electrically connected the first level voltage end Vcc, and first resistor R1's is another
The signal input end 211 of end electrical connection contact signal input end pin3 and second processing unit 21.In this way, when input controlling equipment
1 with host equipment 2 when being electrically connected, and the first level voltage input end, first resistor R1, triode Q1 can be in first processing units
When 11 signal output end 111 has the first signal I1 output, primary Ioops are formed, when the of the base stage b for being sent to triode Q1
When one signal I1 changes, exports to the signal of the second processing unit 21 of host equipment 2 and also change therewith, to meet
The transmission of different signals.So, it is only necessary to which connection can be completed to transmit signal in two ends pin, is conducive to the small-sized of signal interconnecting piece
Change the saving with cost, meanwhile, without providing power supply on signal interconnecting piece, it ensure that the safety of host equipment.
In practical operation, when the first detecting unit 12 detects second signal N (high level signal), and inputs manipulation and set
When transmitting second signal interconnecting pieces 22 of the first signal I1 to host equipment 2 by the first signal interconnecting piece 13 for 1, input manipulation
The first processing units 11 of equipment 1 control the first detecting unit 12 and stop detecting, when input controlling equipment 1 no longer passes through the first news
When number interconnecting piece 13 transmits second signal interconnecting pieces 22 of the first signal I1 to host equipment 2, input controlling equipment 1 control first
Detecting unit 12 continues to detect.System energy consumption can so be reduced.Alternative, when the first detecting unit 12 detects second signal N
After (high level signal), if the first detecting unit 12 of input controlling equipment 1 detects the first signal I1 to continue first again
Preset time T 1 then judges that the first signal interconnecting piece 13 is disconnected with the second signal interconnecting piece 22.
By the way that level voltage input unit to be set on host equipment, detecting unit is set to input controlling equipment
On, by detecting input controlling equipment signal interconnecting piece signal intensity come judge input controlling equipment whether with host equipment
Connection, ensure that the accuracy of detecting result, and level voltage is provided by host equipment, avoid input this kind of movement of controlling equipment
After the electric quantity consumption of communication apparatus, lead to the reduction of level voltage, influences to detect effect.
