Surface contact type bus device

The invention provides a surface contact type bus device. A missile-borne surface contact bus is installed on the surface of an airborne weapon. A missile-borne signal adjustment modulator is connected with the missile-borne surface contact bus. The missile-borne signal adjustment modulator is installed in the airborne weapon. Meanwhile, an airborne surface contact bus is installed in the position, in contact with the missile-borne surface contact bus correspondingly, of the surface of an aircraft. An airborne signal adjustment modulator is connected with the airborne surface contact bus. In addition, the airborne surface contact bus and the missile-borne surface contact bus are each composed of a plurality of contact plates. The contact plates are of a grid structure. The missile-mounted signal adjustment modulator is used for modulating a signal transmitted from the airborne signal adjustment modular and processing the modulated signal into a feedback signal, then the feedback signal is modulated and input
