Abstract

A conductance path mechanism of wireless heartbeat transmitter comprising: a circuit board, a spiral spring, an U-shaped contact rod integrally molded to both side ends of a bottom cover, and a rubber conductible sheet; wherein the horizontal portion of said U-shaped contact rod is totally inserted inside a foundation of a bottom cover to form a steady mechanism; and, one vertical end of said U-shaped contact rod forms three upward vertical pins which are inserted into a rubber conductible sheet to make a steady conductible contact mechanism of insert-connection; the other vertical end of said U-shaped contact rod forms a contact positioning pin which makes a spiral spring collar a contact positioning pin in order to make a superior electrical contact formed by said circuit board and said U-shaped contact rod and to construct a steady conductance path mechanism so as to increase the accuracy of monitored heartbeat signal.

Claims

1. A conductance path mechanism of wireless heartbeat transmitter, comprising an upper cover, a bottom cover provided with a front wall rib and a rear wall rib, a circuit board, two spiral springs, two U-shaped contact rods integrally molded to both left and right sides of said bottom cover, two fixing bands, two rubber conductible sheets, and two pressing plate, wherein the conductance path mechanism of said wireless heartbeat transmitter is included;

said bottom cover further has a left wall rib and a right wall rib at locations connected to near side end of said front wall rib and said rear wall rib respectively, and two rib walls located at the symmetrical side of said left wall rib and said right wall rib to form a spring detent groove;

said U-shaped contact rod has one horizontal portion totally inserted inside the foundation of said bottom cover and two vertical ends, wherein one of vertical ends of said U-shaped contact rods is provided with three upward vertical pins protruded out of the foundation of said bottom cover and inserted into said rubber conductible sheet at the bottom of said fixed band to form a conductible contact mechanism of insert-connection, and the other vertical end of said U-shaped contact rods forms a contact positioning pin which protrudes a height to said spring detent groove to make each spiral springs at both sides of the bottom of said circuit board placed inside the collar of said contact positioning pin; and

the lower section of said spiral spring is tightly inserted inside said spring detent groove to make said spiral spring and said bottom cover form a tight and steady mechanism and to make said spiral spring and said contact positioning pin form a superior electrical contact and an excellent conductance path.

2. The conductance path mechanism of wireless heartbeat transmitter as defined in claim 1, wherein said path mechanism is further installed with a sheet of pressing plate at the front end surface of each fixing band to make said three upward vertical pins of said U-shaped contact rod completely inserted into the interior of said rubber conductible sheet.
