Abstract
A battery contact and shielded enclosure having a high frequency energy filtering characteristic includes a battery contact having a movable portion and a fixed portion, the fixed portion mechanically coupled to a dielectric portion of a carrier having a conductive portion, and a chip capacitor electrically coupled between the fixed portion and the conductive portion the chip capacitor providing a low impedance path from the fixed portion to the conductive portion for high frequency energy on the battery contact.
Claims2
A shielded enclosure having a battery contact with a high frequency energy filtering characteristic for supplying power to the enclosure, comprising in combination:
- an electrically conductive housing having a port through which power is provided to an interior of the enclosure;
- a carrier, mechanically coupled to said housing, having a dielectric portion and a conductive portion, said dielectric portion coveting said port and said conductive portion electrically coupled to said housing and coveting a portion of said dielectric portion;
- a battery contact, mechanically coupled to said dielectric portion, having a first part external to the enclosure and a second part within said interior;
- and
- a bypass capacitor within said interior mechanically coupled to said carrier and having a first contact and a second contact, said first contact electrically connected to said battery contact and said second contact electrically connected to said conductive portion, said bypass capacitor thereby providing a low impedance path from said battery contact to said housing for high frequency energy on said battery contact.
