The invention discloses a modular contact component which comprises a movable contact, a contact guide seat, an
elastic component, a baffle, a
fastener and a wire, wherein the movable contact comprises a
precious metal contact, a guide rod and a conductive core; the
precious metal contact is arranged at one end of the guide rod, and the other end of the guide rod is connected with the wire; the conductive core is arranged inside the guide rod; the conductive core is connected with the
precious metal contact; a step is formed in the middle of the guide rod; a guide hole is formed in the contactguide seat; a contact fixing hole is formed in the baffle; the
tail end of the guide rod is nested into the
elastic component and then fixed in the contact fixing hole of the baffle; the
elastic component is positioned between the step and the baffle; the other end of the guide rod penetrates through the guide hole of the contact guide seat; and the baffle is fixed with the contact guide seat byvirtue of the
fastener. According to the modular contact component disclosed by the invention, after the elastic contact device is assembled and adjusted, the modular contact component is wholly mounted onto a
slip ring main body structure, so that the
contact pressure consistency, reliability and assembling manufacturability of the contact are increased, and losses of
electric energy transmissionat the contact part are reduced.
