摘要:
An electrical switching device has a housing composed of an electrically conductive material, at least one conductor plate having a region of an electrically conductive material and arranged in the housing, plug connection means extending from the housing in a sealed manner, and an element for electrically conductive connection of the conductor plate with the housing. The element for electrically conductive connection includes a mechanically prestressed spring element. The spring element has one end abutting against the conductor plate in the region of an electrically conductive material and another end fixedly connected with the housing.

A plug connection with a plug (11) and an associated counterpart plug or socket (12) is intended to be formed such that shaping strains acting upon it have no or only slight disturbing influence on the contacts (25, 28) of the plug connection. To that end, the plug (11) has a packing element (19), supported on its outside in a contact carrier (14), in the form of an uninterrupted, encompassing radial rubber elastic element which, in addition to a framelike basic body (37), engages socket (12), also contains pinlike retaining segments (41), which are oriented inward, press resiliently against the contact elements (25) of the plug (11) and stabilize them in their position. This plug connection is preferably used in motor vehicles, in whose operation strong shaking strains must be expected, e.g. having Diesel engines.

A rammer for artillery shells with a carriage behind the gun's tube that supports a tray in alignment with the powder chamber, that has a mechanism at the rear to intercept the shell, that travels on slides along a track paralleling the axis R of the tube, that is coupled to a piston-and-cylinder drive mechanism to accelerate toward the tube, and that has a braking mechanism to brake it at a prescribed distance from the rear end of the tube. The braking mechanism has a shock absorber position in the longitudinal midplane of the carriage with a piston that moves against the force of a friction spring inside a cylinder and that has a piston rod projecting forward beyond the front of the carriage with a stop mounted on it, whereby the stop rests directly against the rear end of the tube when the carriage is in the forward and braked position.

In a method for longitudinal sealing of electrical conductors (2) that comprise one or more conductor elements (21) disposed inside an external sheath (22), and comprise cavities (23) between the individual conductor elements (21) and between the individual conductor elements (21) and the external sheath (22), according to the present invention the one end (2a), requiring sealing, of the conductor (2) is immersed in a liquid sealing compound (3), and the other end (2b) of the conductor (2) has negative pressure applied to it. A sealing apparatus (1) suitable for carrying out said method encompasses a supply reservoir (4) for the liquid sealing compound (3) into which the one end (2a), requiring sealing, of the conductor (2) is immersed; and a negative-pressure source (5) to which the other end (2b) of the conductor (2) is connected.

A connector arrangement of a control system with a controller in a motor vehicle is designed so that it can be manufactured advantageously and is reliable in operation.To do so, the connector arrangement and the respective controller are designed so that several separate connector sockets with externally accessible contact elements are arranged on the controller, which is mounted on the vehicle's internal combustion engine as a surface-mounted controller, some of the contact elements being designed as high-current contact elements which are connected directly to one another through busbars running inside the controller.The respective mating connectors can be connected to the connector sockets, the mating connectors being electrically connected to components of the vehicle over cable harnesses or cable segments, where a first mating connector connected to cable segments is composed of partial mating connectors which can be handled independently of one another.

A method and a device for producing a crimp are described. A crimp blank is plastically deformed by a forming tool. In particular when the forming tool is retracted, the force which the forming tool exerts on the crimp blank as well as the distance x by which the forming tool is displaced are measured. A change in the distance x between a position at maximum force Fmax and a position that for the first time is free from forces provides an indication of an elastic recovery, i.e., a spring-back, of the crimp blank. This indication represents a measure of the quality of the produced crimp.

A known fuel distributor for fuel injection systems of internal combustion engines for supplying fuel to at least two fuel injection valves comprises a fuel supply channel and a number of valve receptacles corresponding to the number of fuel injection valves. The valve receptacles each have a valve receptacle opening which communicates directly with the fuel supply channel and into which the connecting segments of the fuel injection valves can be inserted.With the novel fuel distributor, electric conductors for electric connection to the fuel injection valves which are integrated directly into and/or onto the fuel distributor and lead up to the valve receptacle openings. Contact springs are arranged in each valve receptacle opening so that, after insertion of the connecting segment of one of the fuel injection valves the said contact springs establish contact with contact faces, provided on the connecting segment so they are axially offset relative to one another with respect to the longitudinal axis of the fuel injection valve.

A circuit board structure, particularly adapted for use in motor vehicle control devices, features a PC board 1 with two different electronic assemblies, e.g. a power portion 5 and a control portion 4, mounted thereon. A card-edge 9 supports a card-edge connector 10 which is connected by leads 8 to a plurality of terminals 7 arranged intermediate the two assemblies 2, 3. In order to enhance electromagnetic compatibility, the terminals 7 are connected to card-edge connector 10 by means of L-shaped leads 8 which bridge over one of the two assemblies, preferably the power portion or assembly.
摘要:
A multipole electrical plug connection remains functionally stable even under vibrational stresses, in particular during the operation of an internal combustion engine. The plug connection is formed by coupling a first connector to a second connector. Attached to a contact carrier as part of a housing of the first connector are a first pressing element and a second pressing element, via which the two connectors are radially and axially biased when both connectors are joined. As a result, relative movements between the contacted contact elements and contact parts situated in the fixed connectors are prevented. The plug connection is preferably intended for use in automobile manufacturing.

In wiring harness connectors the function of the locking prong is integrated into the cover of the wiring harness connection that is placed on the connector housing, in such a way as to combine the cover and the further locking unit. The cover and the second locking system are configured as an integral part. Provision is also made for positioning cable outlets on both end faces of the connector.
