Abstract
An improvement of heart beat transmitter includes a circuit board, a pair of conductive rubber posts, a housing, a pair of fastening straps and a pair of conductive rubber plates. The housing is provided with a metal plate and installs the conductive rubber plate jointly with the fastening strap. The underside of the circuit board is provided with conductive spring plate or rubber post to establish a conducting loop with the metal plate to avoid the manufacturing difficulty. On the other hand, the conduction therebetween is enhanced. The conductive rubber plate is provided with an insulating layer to reduce the contacting area with skin. Accordingly, the noise interference is reduced and the performance is increased.
