Communication device with antenna retaining device

摘要

A communication device includes a housing (20) and an antenna (10). The housing comprises a retaining portion (22). The retaining portion defines a hole (24) surrounded by an inner wall (21). The inner wall includes a plurality of rib portions (28) parallel to a center axis (220) of the hole. A length of each of the rib portions is shorter than an overall length of the inner wall. Ends of the rib portions cooperatively form a step (27), and a pair of stop walls (29) is formed at opposite ends of the step respectively. The rib portions define a plurality of slots (26) therebetween. The antenna is rotatably attached to the retaining portion. The antenna includes a protrusion (166), and a width of each of the slot is slightly smaller than that of the protrusion. The stop wall and the protrusion cooperatively prevent the antenna from rotating excessively.
