Abstract

A flexible contact device is installed in an electronic apparatus for contacting with the battery and transmitting electrical power from the battery to the electronic apparatus. The flexible contact device for use with a battery includes a fixing part, a first flexible arm, and a second flexible arm. The first flexible arm extends from one side of the fixing part and a contacting part is formed at one end of the first flexible arm. The second flexible arm extends from another side of the fixing part. A pushing part is formed at one end of the second flexible arm. The pushing part pushes the inner side of the first flexible arm. Thereby, the flexible contact device provides enough contacting force and reduces the contacting resistance. The deformation of the flexible contact device is low and the rebound of the flexible contact device is good.

Claims

1. A flexible contact device for use with a battery, comprising:

a fixing part;

a first flexible arm extending from one side of the fixing part, the first flexible arm having a contacting part formed at a distal end thereof; and

a second flexible arm extending from another side of the fixing part, the second flexible arm having a pushing part formed thereon, the pushing part being disposed in contiguous contact with an inner side of the first flexible arm to apply a bias force thereto, the second flexible arm having a through hole formed therein for receiving a portion of the contacting part of the first flexible arm therein responsive to a fixed displacement of the first flexible arm by contact with a battery.

2. The flexible contact device for use with a battery as claimed in claim 1, wherein the contacting part of the first flexible arm has a substantially circular longitudinal cross-sectional contour.

3. The flexible contact device for use with a battery as claimed in claim 2, wherein the second flexible arm has a through hole formed therein for receiving a portion of the contacting part of the first flexible arm therein responsive to a fixed displacement of the first flexible arm by contact with a battery.
