A method for combining an internal insulating sleeve and an external insulating sleeve of an antenna for a communication instrument, including the steps: a coil and positioning and electric connecting members are mounted in the internal insulating sleeve; the internal and external insulating sleeves are slipped one over the other, the internal insulating sleeve has a connecting section partially exposed to the outside; the internal and external insulating sleeves are closed to form a joint between them with a radial thickness for melting; the internal and the external insulating sleeves are sent into a melting machine in which the temperature for melting is set, and a transient electrical turning on for melting is done to combine the internal and external insulating sleeves integrally. The structural strength and durability of the antenna thus is largely increased. |
