Abstract

A selective call receiver (100) includes a receiver for receiving a message and a housing (104) for enclosing a receiver (102). A substantially semicircular arcuate recess (106) shaped in a portion of the housing receives a first substantially semicircular arcuate contact (108) that has a substantially arcuate outer surface which provides a non-movable mechanical coupling with the substantially semicircular arcuate recess (106). The first substantially semicircular arcuate contact (108) has a substantially arcuate inner surface, and a second substantially arcuate contact (114) terminates an end of a wrist band antenna (112'"'"') which has an outer contact surface for coupling with the substantially arcuate inner surface of the first substantially semicircular arcuate contact (108) thereby forming a movable electrical coupling therebetween.

Claims

1. A selective call receiver, comprising:

means for receiving a message;

a housing for enclosing the receiving means, a substantially semicircular arcuate recess shaped in a portion of said housing for receiving a first substantially semicircular arcuate contact having a substantially arcuate outer surface for providing a non-movable mechanical coupling with the substantially semicircular arcuate recess, said first substantially semicircular arcuate contact having a substantially arcuate inner surface; and

a second substantially arcuate contact terminating an end of a wrist band antenna, said second substantially arcuate contact having an outer contact surface for coupling with said substantially arcuate inner surface of the first substantially semicircular arcuate contact thereby forming a movable electrical coupling therebetween.

2. The selective call receiver according to claim 1 wherein the wrist band antenna is disposed within a securing means comprising a flexible watch band assembly.

3. The selective call receiver according to claim 1 wherein the housing comprises a wrist watch enclosure.

4. The selective call receiver according to claim 1 wherein the outer surface of the second substantially arcuate contact comprises at least one protrusion for electrically coupling with the substantially arcuate inner surface of the first substantially arcuate contact.

5. The selective call receiver according to claim 4 wherein the at least one protrusion on the outer surface of the second substantially arcuate contact couples with the substantially arcuate inner surface of the first substantially semicircular arcuate contact for providing a wiping electrical coupling therebetween.
