Solderless battery contact

摘要

Described in this disclosure are battery contacts for use in electronic devices usable without soldering to a circuit board. The battery contact includes one or more contact features supported by leaf springs. The contact features touch a corresponding pad on the circuit board at time of assembly, providing an electrically conductive pathway. One or more of the battery contacts may include a spring-biased member configured to apply pressure to one or more batteries.

主权项

1. A device comprising a battery compartment configured to hold a set of one or more batteries, wherein the battery compartment includes:
a first contact aperture at a first end and a second contact aperture at a second end, wherein the first contact aperture is configured to pass a positive terminal of a battery in the set of one or more batteries through the first end and prevent a negative terminal of the battery in the set of one or more batteries from passing through the first end; a positive battery contact proximate to the first end of the battery compartment, the positive battery contact comprising: a positive contact body having a battery contact feature configured to be mounted in the first body proximate to the first contact aperture, wherein the battery contact feature is configured to contact, through the first contact aperture, the positive terminal protruding from the set of one or more batteries positioned in the battery compartment; and a plurality of leaf springs extending from the positive contact body, each leaf spring including one or more arcuate sections and one or more contact features; a negative battery contact at a second end of the battery compartment, the negative battery contact comprising: a negative contact body having a post and configured to be mounted in the first body proximate to the second contact aperture, wherein the post comprises one or more stiffening features and a coil spring engagement feature; a coil spring arranged along a common axis with the post and having a post engagement feature configured to couple to the coil spring engagement feature; a battery contact cap configured to couple to the coil spring, wherein a portion of the battery contact cap is configured to pass through the second contact aperture and contact a negative terminal on the set of one or more batteries positioned in the battery compartment and the coil spring is configured to bias the portion of the battery contact cap through the second contact aperture; and a plurality of leaf springs in extending from the negative contact body, each leaf spring including one or more arcuate sections and one or more contact features; and a circuit board comprising a plurality of electrical contact pads, the electrical contact pads arranged to come into contact with the one or more contact features of the first plurality of leaf springs and the second plurality of leaf springs upon placement proximate to the first body.
