Abstract: Electromagnetic relay including an insulating base housing, an operating electromagnet arranged on the base housing and a case covering the base housing and electromagnet. A movable contact and a fixed contact are attached to the base housing. The electromagnet includes a flat-plate-form yoke, a winding frame and an armature. The base housing includes a protrusion protruding upward in a vicinity of a first leg of the yoke. The winding frame includes an extension extending from a winding body on a side of the first leg, and which has an upper portion positioned at least above the first leg. The upper portion includes a recess which extends parallel to a direction of extension of the body of the yoke. The armature has a projection protruding upward on the upper end of the pivoting shaft. The projection is positioned inside a space defined by the recess of the winding frame and the protrusion of the base housing.

Abstract: A ball grid array connector having an insulative housing with a plurality of contacts in electrical connection with corresponding solder balls that protrude from a surface of the housing. The solder balls form a soldering region for attachment to a circuit board. The housing has a center of gravity biased from a center of the soldering region, and a positional compensation member is attached to the housing and the circuit board. The positional compensation member prevents the housing from becoming inclined with respect to the circuit board when the solder balls are attached to the circuit board and prevents the housing from becoming inclined with respect to an electronic part when the electronic part is mounted to the housing on a side opposite from the circuit board.

Abstract: Electromagnetic relay having an increased insulating distance between a primary side circuit consisting of an excitation coil and an armature and a secondary side circuit consisting of a movable contact and a fixed contact, so that the withstand voltage of the relay is increased in comparison to prior art electromagnetic relays. The electromagnetic relay includes a base housing having a first insulating wall extending between the excitation coil and the armature, and a second insulating wall separating the movable and fixed contacts and the armature. An operating part of the relay presses the movable contact via a hole formed in substantially the central portion of the second insulating wall of the base housing.
