Abstract: An electrical connector assembly according to the current invention comprises a receptacle and a composite action beam. The composite action beam is located in the receptacle and has a movable end and a fixed end. During initial phase of insertion cycle, a movable end of the composite action beam moves as the pin is inserted into the connector. This movement reduces insertion force. During an intermediate phase of the insertion cycle, the movable end reaches the inside wall of the connector and the composite action beam now functions as a two-end supported beam. The composite action beam thereon exerts sufficiently high normal force against the inserted pin so as to retain the pin in the inserted position. Thus, the composite action beam reduces insertion force without compromising normal force once the pin is inserted.

Abstract: An electrical terminal comprises an inner contact body and an outer spring body. The outer spring body is box-shaped and encloses the inner contact body. The outer spring body comprises spring beams edge-stamped out of top and bottom walls respectively. Protrusions are positioned centrally along the spring beams, and project beyond side walls of the outer spring body such that when the terminal is inserted into a corresponding housing cavity, the protrusions interfere with walls thereof. The spring beams are thus resiliently biased and the terminal is resiliently held within the housing cavity such that chattering of the terminal therein is prevented. Vibration movements parallel to the top and bottom walls causes the spring beams to act in the plane of the metal, and vibration movements perpendicular thereto cause the spring beams to act in torsion. Due to the edge-stamping of the spring beams out of top and bottom walls, they are very simple to manufacture, yet very effective, robust and reliable.

A method of making the connector includes a step of press-fitting the power contact member into the one passage from the interior compartment with the contact member circular portion leading the contact member blade portion, such that the circular portion is in interference fit in the one passage and that the blade portion is resident in the interior compartment.

Each flange face has about the same radius of curvature (C) as that of the hole, and the web is narrower than the flanges, but thick enough to avoid substantial bending.

This connection arrangement is used, inter alia, when contact is made between the connecting wires (12) of coils.

Abstract: In a connector comprising: a connector housing having a terminal accommodating chamber with a flexible terminal locking extended in the latter; and a terminal having a male tab at the end, which is inserted into the terminal accommodating chamber with the male tab protruded through an opening of the terminal accommodating chamber; a pair of swing preventing protrusions are formed on the inner wall of the terminal accommodating chamber at the end on the side of the opening, which wall is confronted with the terminal locking arm, in such a manner that the protrusions form a hole for insertion of for the male tab, each of the swing preventing protrusions has a first sloped guide surface on the terminal insertion side, and a second sloped guide surface on the side in opposition to the terminal locking arm, and a male tab receivable space, which is relatively wide, is formed using the second sloped surfaces, whereby the terminal can be smoothly inserted into the connector housing without play.

Abstract: An electrical terminal (10) including a contact section (14) extending from a body section (12), and a pin section (16) extending from the body section to be inserted into a circuit board through hole (20). The pin section (16) is defined by a pair of spaced apart opposing legs (30) each having a compliant portion (42) defined by a pair of arcuate beams (48) spaced apart by a slot (50), the arcuate beam pair at outer edges (54) being larger in dimension than the through hole diameter. Insertion compresses the arcuate beams (48) of each pair together generating force in a first direction, and compresses the legs toward each other generating force in an orthogonal direction.

Abstract: An electrical connector comprises, an insulating body, electrically conductive posts projecting from the body and extending outwardly for insertion along apertures of a circuit board, each of said posts being one of three types, a first type having a protrusion adapted to engage a circuit board and prop the body to prevent the body from tipping over while the body is engaged against a circuit board, a second type having a retention feature tending to retain the body engaged against a circuit board, and a third type having neither said protrusion nor said retention feature.
