Abstract
A plate shaped heater for heating a heat shrink tube on a cable includes a housing, multiple heating tubes arranged within the housing, and a heating wire arranged in the multiple heating tubes. The housing defines opposite ends in its longitudinal direction. The heating tubes extend along a transverse direction of the housing and are arranged in a row along the longitudinal direction of the housing. An arrangement density of the heating tubes in two end regions proximate two ends of the housing is greater than an arrangement density of the heating tubes in a middle region between the two end regions of the housing.
