DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a multi-polar contactor device including a structural body member which laterally encloses a contact wafer member disposed in the structural body member. The contactor device includes a first end aperture for connection of the leads, and a second end aperture, by the intermediary of which the contactor may be interconnected with a coupling member which may include another coupling member, connection strip etc.
So-called contactor wafers are already well-established in electrical contact technology. Such a contact wafer consists of a flat unit including a number of parallel-disposed contactor members (plugs, jack plugs) which are baked into/disposed in a body of plastic or the like. A ribbon cable or the like may be connected to the contactor wafer. In such an instance, the contactor wafer is disposed in a structural body which, together with the contactor wafer, forms the contactor device. The latter is interconnected with a corresponding (compatible) connector device, connection strip, etc.
Contactor devices of the above-mentioned types may be employed in coordination with one another, so that it is possible to form a large number of connection points (jack plugs) in a thus formed unit.
SUMMARY OF THE INVENTION
In the prior art, problems are experienced in achieving a number of contact points, which could be satisfied in number, space and mutual location, by contactor devices of current standards. For example, placing two contactor devices of the above-mentioned type adjacent to one another entails that the contactor device density will be relatively small because the walls of the outer structural bodies of adjacent contactor devices reduce available space and so on.
The object of the present invention is to realize a contactor device which solves the above-disclosed and other structural problems. The novel feature of the apparatus according to the invention is that the structural body member is provided with one or more compartments which may each be allocated with a contactor wafer so that two or more contactor wafers may be placed in the body member and together therewith form the contactor device.
According to another feature, one of the side portions of the structural body member is disposed so as to be disconnectable even when the contactor device assumes an interconnected position with the above-mentioned coupling bodies (another contactor device, connection strip, etc.). In the above-described position, at least half of the contactor wafers are disconnectable/connectable from and to, respectively, the coupling members. In one preferred embodiment, the contactor wafers in the compartments are disposed in two parallel adjacent rows, seen in the horizontal section of the contactor device. The contactor wafers which are placed close to the removable side section, will be disposed for disconnection and connection when the side section is removed and the contactor device is interconnected with the coupling member.
The inventive concept as herein disclosed includes contactor devices which enclose contactor wafers with the same and/or a different number of conductors. In the event of a differing number of conductors, the contactor wafers in the compartments of the body member are of different sizes.
The subject matter of the present invention is preferably disposed in compact electronics equipment of the type which is used in, for example, sighting units. The subject matter of the present invention is also highly suited in electronic equipment, which is to be resistant to or insensitive to electromagnetic interference (EMI). In such an instance, the contactor device is cooperable with an outer unit of metal/alloy which encloses the contactor device and coupling member and which acts as a screen against the electromagnetic interference (EMI). This outer unit may be included in another enclosure unit for electronics of the above-mentioned type. The enclosure unit may include an extension along its one longitudinal size. The extension includes
