Abstract: In a process for fitting a round cable provided with a number of single wires with a multi-way, preferably flat, plug into which the single wires are placed, the single wires have their free ends stripped of insulation and are fitted with contacts. In such a process, assembly can be carried out in a cost-effective manner and the risk of damage to the small contacts is greatly reduced. Provision is made for the single wires to be placed alongside each other in a wire holder of the plug, for the ends projecting beyond the wire holder to be cut to the same projecting length and stripped of insulation to the same length and for a contact carrier to be provided with the corresponding number of adjacent contacts and connected to the end of the wire holder receiving the single wire ends, and for the opposing regions of stripped single wire ends and connection elements of the contacts to be interconnected to make electrical contact.

Abstract: The invention relates to a switch configuration that can be used in a receptacle that is equipped with a shield. In this case, the shield can be arranged offset relative to the receptacle within the framework of given tolerances. The novel switch arrangement is used to compensate for the offset of the shield relative to the receptacle with the aid of a cap that is mounted in a floating manner. In this case, the friction of an actuation cap, which actuates a switch via an actuator, is to be kept as low as possible relative to the guide surfaces of the corresponding shield opening.

Abstract: A night vision binocular assembly (10) capable of converting low light and infrared energy into a visible image. The night vision binocular assembly (10) includes at least one objective lens assembly (62), image intensifier tube (64), collimator lens assembly (66) and diopter cell assembly (68) encased in an easy to assembly waterproof housing (16). The objective lens assembly (62), image intensifier tube (64), collimator lens assembly (66) and diopter cell assembly (68) are all supported by a common base structure (80) within the housing (16). As a result, variations caused by thermal expansions and contractions are evenly distributed among the various optical elements, thereby preserving a predetermined optical relationship between those elements. Simple button controls (28, 30, 31) are used to operate and adjust the night vision binocular assembly (10). The button controls (28, 30, 31) are disposed on a common circuit board (38).

Abstract: A plug-receiving connector is provided, which includes a molded plastic housing (12) for mounting on a circuit board, which minimizes stress on the plastic housing in mounting it and in latching to a mating plug. A sheet metal bracket (14) has a top plate part (46) that lies over the top wall (28) of the plastic housing and has a pair of depending sheet metal parts (47, 48, 58, 59) at each of the opposite sides of the top plate part. One of the depending sheet metal parts of each pair is a holding tab (58, 59) that extends through a slit (31, 32) in the plastic housing top wall, through a plug-receiving cavity (16) formed by the housing, and into a slit (33, 34) in a plastic housing bottom wall (29). Each of the second depending sheet metal parts comprises a sheet metal side (47, 48) that lies closely outside a corresponding plastic housing side wall (26, 27), so each plastic housing side wall is sandwiched between a sheet metal holding tab and a sheet metal side.

Abstract: A radar system is described, which includes a built-in calibration/fault detection apparatus that enables rapid and easy calibration of the system. The system includes a long extrusion (70) forming a feed waveguide (90), a calibration waveguide (92), and a base (94) of a horn antenna. A linear array of TR (transmit/receive) units (42) are mounted on the extrusion, with each having a feed probe (100) that receives a feed signal, changes its phase and amplifies it, and delivers it through a monopole (110) to the horn. The calibration waveguide is coupled through holes (130) to the horn, with a calibration pickup (132) mounted at the end of the calibration waveguide. During calibration, one TR unit at a time is energized, and its output is detected by the calibration pickup to check the amplitude and phase of the TR unit.
