Abstract: The present invention relates to an ignition coil for ignition systems, in particular a rod ignition coil for internal-combustion engines, comprising at least one primary winding and at least one secondary winding, a high voltage being induced in the secondary winding when current flows in the primary winding. A ferromagnetic core is surrounded in part by the primary winding and the secondary winding and one of the two windings is additionally surrounded at least in part by the other. To provide an improved ignition coil which ensures increased reliability in operation and energy efficiency and a reduced risk of overheating during operation, at least one of the windings comprises at least one portion having an elevated winding density relative to the remaining winding density, the diameter of the innermost turns in the at least one portion being smaller than the diameter of the innermost turns in the remaining winding portions.

A seal member has a plurality of adjacent wire receiving through-holes through which the electric wires extend. The seal member has cylindrical areas around a circumference of each of the wire receiving through-holes. The cylindrical areas partially overlap to form a continuous integral structure. The seal member is formed from an elastomer.
Abstract: An electrical connector has an insulating housing provided with first and second contacts. A positioning guide protrudes from a mating surface of the housing. At least one barrier wall is formed between the first and second contacts that separates the first contacts from the second contacts. A mating connector has an insulating mating housing provided with first and second mating contacts and a positioning recessed member that receives the positioning guide. A barrier wall recessed member is formed between the first and second mating contacts that separates the first mating contacts from the second mating contacts. The barrier wall recessed member receives the barrier wall when the electrical connector is mated with the mating connector. A shutter member is provided on the mating connector and is moveable between an upper position and a lower position. The shutter member covers the first and second mating contacts in the upper position.
Abstract: A connecting arrangement includes at least first and second housings in which at least one conductor of a first cable can be electrically connected to at least one conductor of a second cable fed via a cable receiver. At least one piercing element is electrically connected to the second cable and configured to be inserted transversely into the conductor of the first cable. The cable receiver is constructed as an integral unit with the second housing and the piercing element. A sealing element configured to seal a piercing point of the piercing element is arranged on an inner side of the second housing and the cable receiver is disposed on an outer side of the second housing. The sealing element and the cable receiver are formed in one piece through the second housing.

Abstract: An electrical connector for flat cables has an insulative housing, contacts and a shield member. The insulative housing is mountable onto a circuit board having a conductive pad. The contacts are disposed in the insulative housing for contacting a shield of a flat cable to be inserted into the connector. The shield member is mounted on the insulative housing so as to substantially cover the outer surfaces thereof and electrically connect the shield of the flat cable to the conductive pad of the circuit board when the shield member is mounted on the insulative housing.
Abstract: The present invention provides a crimping apparatus that can adapt widely to various diameters of the insulating coatings of wires. The crimping apparatus has a crimp height adjustment mechanism for an insulating coating of a wire, the front of the crimping apparatus facing in a direction opposite to the direction of a core of the wire. The adjustment mechanism includes a shaft member having a regular polygon part and an eccentric shaft part that are connected thereto, and an adjustment dial which is disposed in the eccentric shaft part so as to face in the same direction as the front of the crimping apparatus. Therefore, this crimping apparatus can perform the crimping of terminals having various diameters of the insulating coatings of wires.
Abstract: An electrical component comprises a housing having a plurality of compliant pins. A circuit board is provided with though-holes. Each of the through-holes has an inner surface with a plating layer. Each of the compliant pins has an elastic press-fit portion with an outer surface provided with a step. The step has an engaging surface that engages the plating layer of the though-hole to secure the compliant pin therein. The engaging surface has a width in a direction substantially perpendicular to the inner surface of the through-hole smaller than a thickness of the plating layer.
Abstract: A plug (10) for connecting to a plug socket comprises a plug contact region (18) having one or more contacts for producing one or more electrical connections between the plug (10) and the plug socket. The plug also comprises a latch spring (32) having a first plug latching element (36) for connecting the plug (10) to a first socket latching element of the plug socket and a second plug latching element (38) for latching the plug (10) to a second socket latching element of the plug socket.

Abstract: A card connector comprises an insulating housing having a first card receiving slot provided with a plurality of contacts. At least one elastic projection extends into the first card receiving slot. The elastic projection is formed to have a first inclined surface that rises at an inclination in a card insertion direction and a second inclined surface that rises at an inclination in a card removal direction. The second inclined surface is steeper than the first inclined surface. A first card electrically connected to the contacts. The first card is removeably receivable in the first card receiving slot and has a flange protruding from a main surface thereof. The flange is formed to engage the first inclined surface when the first card is inserted in the first card receiving slot and to engage the second inclined surface when the first card is removed from the first card receiving slot.
Abstract: A programmable system for testing relays and controlling systems is provided. In one embodiment the present disclosure provides a programmable device capable of, for example, testing relays. The device includes a signal generator for generating signals to test relays. The device includes a memory location, and a first program stored in the memory location. The first program supports relay testing. The device includes a versioned program to support relay testing, and a processor in communication with the signal generator and the memory location. The device also includes a routine that is operable by the processor to install a versioned program in the memory location replacing the first program.

Abstract: An apparatus for positioning and press-fitting press-fit portions of roughly L-shaped legs of contacts arranged in multiple rows in a connector into a substrate includes a press-fitting head and an alignment plate. The press-fitting head is rotatable between a rest position and a press-fitting position and has vertical grooves for receiving the contacts in the press-fitting position. The alignment plate is arranged proximate the press-fitting head when the press-fitting head is in the press-fitting position and aligns the press-fit portions of the contacts with press-fitting apertures in the substrate. The alignment plate is retracted from the press-fitting head when the press-fitting head press-fits the press-fit portions into the substrate.
Abstract: A docking connector comprises a first connector and a second connector. The first connector has an insulating first housing. The first housing includes guide pins that extend from a mating surface of the first housing. The guide pins are moveable toward and away from the first housing. The guide pins are locked in a position away from the first housing by a locking member. The second connector has an insulating second housing. The second housing includes guide pin receiving openings that receive the guide pins. The second connector has a lock release member for unlocking the guide pins during insertion of the guide pins in the guide pin receiving openings.
