A high voltage electrical connection includes an electrical receptacle connector and a mating electrical plug connector. The electrical receptacle connector includes a receptacle that is mounted over a hole in the casing and fastened thereto with a plurality of terminated electrical leads that are attached to an internal component of an electrical device inside the casing and threaded through a hole in the casing. The receptacle has a chamber including an inlet at one end that is aligned with the hole in casing and an outlet at the other end. The electrical receptacle connector also includes a terminal holder and a terminal housing, both of which are made of electrical insulation material. The holder retains the plurality of terminals, of the respective leads is inserted into the chamber through the outlet of the receptacle and retained in the chamber. The terminal housing is then inserted into the chamber via the outlet with its flange being disposed in the outlet. The flange has a plurality of spaced holes, each one of which receives one of the plurality of terminals. Flange includes a stop to locate the terminal housing with respect to the receptacle in a longitudinal direction of the terminals, and an integral shroud that extends outwardly of the outlet whereby the electrical receptacle connector is adapted to receive the mating plug connector. The mating electrical plug connector which includes a plurality of terminals each attached to one of a plurality of electrical leads, a connector body housing the plurality of terminals, a terminal position assurance (TPA)/wire dress feature for the plurality of terminals and electrical leads, and an, electromagnetic interference (EMI) shield.

A slide contact electrical connector preferably for an oxygen sensor is assembled in such a way as to protect the precious metal surface of multiple contact pads of an edge card . The edge card is encased by a ceramic capsule . Trailing portions of terminals are laterally inserted into longitudinally extending channels of a core being radially and axially locked in place. The terminals extend forward from the core and are positioned about the trailing end of the edge card from a longitudinal direction. A collar compresses the terminals against the edge card from a lateral direction thereby making the electrical contact. A shield encircles the capsule , collar , terminals and core thereby protecting the electrical connection integrity. A seal is disposed at a trailing end of the shield penetrated by a plurality of insulated electrical wires

Slide contact electrical connector

A sleeve terminal which provides a continually assured level of normal force with respect to a received pin terminal, even as the sleeve member thereof may tend to relax over time. The sleeve terminal includes a sleeve member having a slot which allows the sleeve member to be resiliently expanded when a pin terminal is inserted therewithin. A pair of resilient arms characterized by an opposing V-shape are formed integrally with the sleeve member on opposing sides of the slot. The apex of the resilient arms provides a contact location with the inner surface of a barrel which is concentrically receives the sleeve terminal. A free end of each resilient arm is spaced a predetrmined distance from the sleeve member. A wire mount is connected to the sleeve member opposite the slot. In operation, a pin terminal is inserted into the sleeve member, causing the sleeve member to be resiliently expanded as the slot widens. The sleeve terminal is then received into a barrel, during which operation the resilient arms tend to become flattened, eventually resulting in the free ends abutting the sleeve member, whereupon any further compression of the resilient arms is accompanied by an increased application of normal force against the inner surface of the barrel in one direction and against the sleeve member, and in turn the pin terminal, in the opposite direction.

An improved IDC trim resistor connector assembly made up of a generally open top cup shape connector with side wall slots and an interior first array of terminal posts arranged for passage therethrough of a first lead wire of sensor circuitry. A first stamped metal IDC terminal is push-on mounted on the terminal posts for IDC cradling and electrically and mechanically receiving and connecting to the first lead wire. A conventional trim resistor substrate is loose mounted but accurately positioned on the connector bottom wall and has an &ldquo;E&rdquo; pattern of resistive material adapted for center leg laser trimming to calibrate the associated sensor circuitry. A first IDC terminal spring leg overlap contacts one side leg of the trim resistor E-pattern and thereby spring clamps the resistor substrate. A cover is snap-latch mounted on the connector and has an access opening to enable laser trimming of the trim resistor after cover installation. One end of a second lead wire is received in a second IDC metal terminal in turn mounted on a second array of connector-interior terminal posts and also having a spring leg overlap electrically contacting and clamping the other E-pattern side leg. Spring barbs on the terminals anchor the same once fully inserted downwardly onto the terminal posts. Connector locking tangs and cover locking ears provide snap-on retention of the cover on the connector, and press-in/keeper internal cover projections cause push-down assembly of the lead wires as the cover is latched onto the connector. Cover locking tangs and cap latching ears provide snap-together locking of a cap on the cover when the cap is pushed down on the cover to seal the access opening after completion of laser trimming and in-filling of the covered container with sealant. In a second embodiment a crimp-type terminal, also provided with a spring clamping leg, is fastened to the second lead wire and has a barbed mounting strap clasping a modified second terminal post array when fully installed thereon.

A low profile electrical bussing plate for electrically connecting a plurality of spaced pin terminals carried by an insulated housing of an electrical connector assembly, the housing having a planar face from which the terminals project and which is matable with an insulated housing or member for connection with the housing having an end face for engaging and holding the bussing plate against the planar end face of the housing when connected thereto. The bussing plate includes an elongated planar base plate having a plurality of spaced apart, generally rectangularly shaped openings, a plurality of spaced pairs of first and second arms integral with the base plate along its opposite elongated sides and located transversely of the openings and with the arms each being folded across the base plate toward each other and bent to provide arcuate portions which face one another. The first and second arms at the free ends terminated adjacent the plane containing the base and are deflectable when engaged by a pin terminal upon the latter being inserted therebetween to biasingly engage the pin terminals and the bussing plate having first and second sides respectively integral with the side edges of the openings and extending perpendicular to its base so as to straddle the first and second arms and align the pin terminals in the bussing plate.

An electrical connector comprises a connector body having two rows of terminal cavities that are on opposite sides of a divider wall that terminates in a tapered projection that extends part way into a common lateral slot at the cable end of the connector body. A bifurcated lock member is attached to the connector body to prevent withdrawal of the electrical terminals disposed in the terminal cavities. The bifurcated lock member has two plates that are spread apart by the tapered projection so that substantially the ends of the plates are solidly behind short stop tabs of the electric terminals in the respective rows.

An electrical header assembly for a printed circuit board or the like comprises a housing of thermoplastic material having a mating portion and a conductor portion and a row of laterally spaced insert molded blade terminals of stamped sheet metal construction. The blade terminals have tails which are bent vertically in a secondary bending operation to provide vertical legs which are positioned and retained by laterally deflectable walls defining channels at the end of the conductor portion of the housing. The housing has a narrow peripheral groove which is defined by confronting faces of the mating and conductor portions of the housing and which is adapted for mounting the electrical header connector on an apertured panel wall.
