DD200252A1 - CONTACT DEVICE FOR ELECTRICALLY SEALING CLOSURE OF VISOR ELEMENTS - Google Patents

Abstract

The invention relates to a contact device for the electrically sealed closure of shielding elements, in particular applicable in electronic and telecommunications devices. The object of the invention is to achieve an electrically sealed and secure closure of shielding elements by this contact device, wherein the same is technologically efficient to produce and easy to assemble and thus a uniform and electrically secure contact between the upper and lower part of the shielding elements is guaranteed. According to the invention, the object is achieved by using a spring element with a pyramid-shaped roof structure, having a V-shaped tongue and provided with a plurality of stable contact points.

Title of the invention

Contact device for the electrically sealed closing of screen elements

Anwe area of the invention

The invention relates to a contact device for sealing of shielding elements, in particular of shields and cassettes in electronic and Nachriehtentechnischen devices.

Characteristics he d be known technical solutions

It is known that in electrical engineering, electronics and telecommunications, especially when working with high

• Erequenzenj often electrically sealed cassettes and shielding systems are needed.

Various shielding constructions are known which. are divided by intermediate walls into several chambers, are partially pluggable and can be fixed by suitable holes, lugs or pins by soldering each other and on circuit boards. Such cassettes or shielding systems are preferably made

- Metal "manufactured and are usually closed by a lid for sufficiently secure electrical shielding of the respective components or assemblies.

   2 · -

The disadvantage here is that the electrically sealed closing of the shields and cassettes by screwing or soldering the lid with the cassette base is done · It is also known for contact connection between the cassette and shield top and bottom slotted or chamber-like spring elements, which are firmly connected to the cassette lid are and sit when closing the cassette on the walls. The disadvantage here is the complex production and assembly,

Object of the invention

The aim and purpose of the invention is to eliminate the known disadvantages in closing cassettes and shields taking into account high-frequency technical requirements by a suitable contact device largely ·

Explanation of the essence of the invention

The invention has for its object to develop a contact device for an electrically sealed and secure closing of cassettes and shields, which is technologically rational and producible by simple mounting on appropriate cover, cassette or Abschirmrahmenwandung can be placed and so a uniform and electrically secure contact of the According to the invention, the object is achieved in that a spring element has a pyramid-shaped roof structure which is provided with a plurality of stable contact points and thus allows a resilient, line-shaped contacting possibility, wherein the spring element has projecting tongues, according to the invention be made by suitable partial tearing and bending. The walls

or Deckelabkantungen receive corresponding breakthroughs into which engage the tongues of the spring elements, whereby a secure and captive connection of the spring is made with the wall _e ·

Execution example

The invention will be explained in more detail below using an exemplary embodiment, in the attached drawing

Fig. 1 Eontaktvorrichtung in side view Fig. 2 Eontaktvorrichtung in plan view .Fig. 3 contact device between the lid and the cassette wall

The spring elements 1 according to the invention are pushed in a simple assembly on the respective wall 4- or cover edge 5, wherein the tongues 2 of the same engage in the corresponding openings 3 and as a captive connection of the spring element 1 with the "wall 4 · and the cover edge 5 is formed.

The pyramidal roof structure of the spring element 1 guarantees when placing the lid 5 on the cassette wall small resilient contact with a plurality of linear contact points.
