A connector bank with two rows of insulation displacement contacts for connecting insulated conductors, in particular of cables for telecommunication and data systems, comprising a surge arrester magazine to be inserted into the connector bank. In order to provide a connector bank having a voltage surge protection and allowing connecting and disconnecting as well as testing the attached cable conductors at the insulation displacement contacts even with inserted voltage surge protection, the two rows of insulation displacement contacts are arranged on different sides of the connector bank. An insulation displacement contact of the first row is connected over a connecting element with an insulation displacement contact of the second row. The surge arrester magazine is arranged laterally approximately centrally between the two rows of insulation displacement contacts.

A thermal protection device for overvoltage suppressor which includes spaced contacts 6 mounted in overvoltage suppressor magazines 11 of communication systems. A bow-type spring 3 and a melt element 2 l are arranged with the overvoltage suppressor which is mounted in a chamber of a case body or housing 13. The melt element is pierced by at least one arm of the bow-type spring when an overvoltage occurs for short-circuiting the two contacts of the overvoltage suppressor. A thermal protection device with simple components prevents creepage currents between the bow-type spring and the contacts of the overvoltage suppressor 6, a chamber for the overvoltage suppressor is adjacent and abutting to a separate chamber formed in the case body for accommodating a bow-type spring. Between the two chambers there is a separating wall comprising a thermoplastic melt element.

A plug connector for printed circuit boards includes a number of contact elements positioned in a housing. The contact elements each have two connection ends and an intermediate contact positioned between the two ends, where one connection end is in the form of an insulation displacement contact for connecting wires. The insulation displacement contacts are supported on the housing, so that the contact elements are held captively in the housing when connection forces act on the insulation displacement contacts.

The invention relates to a plug-in connector for printed circuits, comprising a plurality of contact elements, whereby said contact elements have two connecting faces each. The one connecting face is configured as an insulation displacement contact for connecting cores and the other connecting face is configured as a tuning fork contact for contacting contact surfaces on a printed circuit. The insulation displacement contacts of the contact elements can be inserted into a plastic housing. At least one lower edge of the insulation displacement contacts is supported on the plastic housing so that the contact elements are captivated in the plastic housing when connecting forces act upon the insulation displacement contacts. The plastic housing comprises at least one chamber-type area. The tuning fork contacts are completely received by the plastic housing in the longitudinal direction. The contact element is configured as a two-part element, a first part of the contact element comprising the insulation displacement contact and the second part comprising the tuning fork contact. One contact arm each is positioned on both parts of the contact element and the two contact arms interact to give a disconnector.
