Abstract
An improved earthing connector, especially for earthing components or devices, e.g. screen filters in particular, for display screen work stations, are distinguished in that the earthing connector (15) is electrically connected to an earth conductor in a contact (I) and is in contact with a corresponding contact body (3) or is connected to the earth conductor in the contact body (3) via a separate earthing cable (25).
Description
.
Ear thing contac t The invention relates to an earthing contact, in particular for 8creen filters, keyboard hand-rests and 5 the like, according to the preamble of Claim l.
80-aalled screen filters are oten fitted on the front end of ~ monitor not only to improve the picture display on a monitor but al~o, above all, to shield the electromagnetic radiation issuing from the monitor. This 10 is particularly ~dvisable especially where the monitors were manufactured les3 recently.
Fur~h~ ~~e, it is also known in principle that, for example, the keyboard~ and/or the hand-rests which may or may not be used can, under certain circumstances, 15 become statically charged.
For this reason, anti~tatic armrests, ball of the thumb rests, keyboards or generally antistatic supports, too, are also known. These can be at least surface-conductive, but as a rule preferably volume-conductive.
20 Volume-conductive meana that the material a8 a whole i9 conductive, rather than just its surface.
~ Iowever, in order to achieve the co~le~ ding effect, it is necessary to earth these at least surface-conductive and preferably volume-conductive rests or 25 supports, including, for example, the screen filter which can be mounted in front of or on the front end of a monitor .
For this purpose, the correaponding mounted devices are provided with an earthlng cable on which, as 30 a rule, a term;n~l is fltted by which the cable can be clamped to a sultable earthed object, such as, for ~xample, a heating .~lement cr radiator, a ve~tilation filter of the computer, etc. Examples of earthing are disclo8ed, inter alia, in US-A-4 717 3~9, DE-U-8B 09 799 AMEllDED E;URI~'r 2 ~ 89~73 and G}3-A-88 64 64.
The object o~ the pre3ent invention, by contrast, i~3 to provide an improved earthing exclusion [sic]
possibility for 8uch mounted parts to be earthed, in 5 particular in the field of computers.
The ob~ect is achieved according to the invention by the features specified in Claim 1. Advantageous refinements of the invention are ~pecified in the ~aubclaim3 .
10 The preaent invention use~ extremely simple technical measure# to provide for the fir~t time an ;, .,v~ - t having optimum suitability for such purposes.
8pecifically, it iB provided according to the invention that the earthing connection is formed on a plug contact it~elf or is connected to a lead which leads to a plug contact, the mains plug or the mains aocket of a mains cable serving as plug contact. A~ a rule, such mains cables are nowadays provided with a machine connector, that is to Elay a machine E~ocket, which can be plugged to or onto a monitor-~ide machine plug connection. In other words, the earthing connection according to the invention can bc formed on this cable-~aide machine plug or on this machine Elocket or can be provided on a cable which leadn to the machine plug or to the machine socket.
In a particularly preferred embodiment of the invention, however, the earthing connection is formed on an intermediate plug or contact connector. 8uch a compact int~ te element, which is also referred to below as nn int~ te plug contact, COnE~il3ts of a machine plug and a machine ~ocket formed at the opposite end. The machine socket is plugged, for example, into the corre-apondlng monitor plug connection. The machine socket of the monitor mains cable can then be plugged in on the freely acces~ible machine plug. Tho earthing connectlon iE~ then provided on thiE~ int{~ te plug contact, conceived a~ a separate component, or on a cable connec-tion issuing from the intermediate plug contact.
The earthing contact on the plug contact can have AN~lDl~D Sm; l~T

In uae, for example, a customary maina cable of a monitor cable ia not connected directly to the monitor 15 but rather with the interpoaition of the plug oontact 1 illuatrated in Figurea 1 and 2. In other words, for example, the end connection part of the plug contact which forma the machine aocket 5 ia plugged in and connected to the COL~ OO~u~,ding connection of the monitor, 20 in order then to plug the monitor maina cable, that ia to say the machine plug, into the machine plug 9 formod on the plug contact 1.
