Abstract

A plug has a two-part housing accommodating a printed board with an electrical screening element for preventing propagation of electrical disturbing radiation during the operation of a gas discharge lamp. A mass of a durable elastic material such as silicon is applied on a part of the periphery of at least one screening element between the screening element and the adjoining housing part. The inner space of the housing is filled with a casting mass of an electrically insulating material in which also an elastic mass is enclosed. The elastic mass uncouples the screening element from the housing and from the casting mass, so that a thermal expansion of the screening element is possible and also vibrations of the plug are not rigidly transmitted to the screening element.
