    摘要： A miniaturized electromagnet has an enhanced armature attraction force and reliable armature movement. The electromagnet comprises an L-shaped flat magnetic plate of magnetic material with a horizontally extending core and a first yoke leg depending from one end of the core. An excitation coil is wound around the core. A second yoke member is formed separately from the magnetic plate into a plate configuration and is coupled secured at its upper end to the other end of the core so as to depend therefrom in an opposed relation to the first yoke leg. The lower end portion of the second yoke leg is bent toward the first yoke leg to define thereat a pole plate extending parallel with the core. An armature extends in a parallel relation to the core and is magnetically coupled at its one end to the first yoke leg and is pivotally supported adjacent thereto such that the armature is pivotable within a horizontal plane between set and reset positions of having the pole end attracted to and spaced away from the second yoke leg in response to the energization and deenergization of the excitation coil, respectively. With the provision of the pole plate extending toward the first yoke leg, the armature can be made to have a correspondingly reduced effective length and equivalent mass, whereby the armature can have an increased magnetically attraction force for reliable electromagnetic operation.

    摘要： An electromagnetic relay has a base provided with an insulation enclosure and with a contact block outwardly of the enclosure. An electromagnet block is received within the enclosure and includes a coil, yokes, and an armature extending through the coil along the length of the enclosure. The armature is magnetically coupled to the coil and is movable relative to the yokes upon energization of the coil. A card is provided to connect the armature and a movable contact of the contact block for closing and opening the contact. A cover fitted on the base includes an insulation partition which extends between the enclosure and the contact block to accomplish a double-wall insulation between the electromagnet and the contact block. The card has a trunk for connection with the armature and a crosspiece for connection with the movable contact. The trunk extends into the enclosure through a front is opening thereof to fit around the end of the armature such that the entire length of the armature is insulated from the contact block by the enclosure and by the trunk. The crosspiece extends from the trunk longitudinal outwardly of the enclosure for connection with the movable contact outwardly of the insulation enclosure and partition. Further, the partition is contiguous along substantially the entire length of the enclosure. With these features, the relay can have an improved double-wall insulation between the electromagnet block and the contact block without leaving any insulation break along the length of the electromagnet block.

    摘要： The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion. The electrical leads extend into the concave to make electrical connections between the elongate sheets and the electrical leads. In the present invention, since the piezoelectric element can be attached accurately at a predetermined direction to the supporting member by forcing it into the slit, it is possible to stably supply the acceleration detector having excellent sensitivity to the acceleration without causing variations in detecting direction of the acceleration.

    摘要： A polarized electromagnetic relay having a pair of first and second pole members which are magnetized to opposite polarity by a permanent magnet coupled thereto and which define therebetween a magnetic gap into which the other end of the armature extends. The first pole member and the armature are magnetically coupled to the base so as to cause a magnet flux of the permanent magnet to circulate through the second pole member, the armature, the base, and the first pole member for attracting the armature to the second pole member. Upon energization of the coil, a resulting coil flux circulates through the armature, the base, and the first pole member in opposing direction to the magnet flux for attracting the armature to the first pole member. A cover and base of magnetic material is included to fit over the base and be magnetically coupled thereto. The second pole member is disposed adjacent to the inner wall of the cover so as to define therebetween an air gap which is cooperative with the second pole member, the armature, base, and the cover in order to circulate an additional coil flux in the opposing direction to the magnet flux across the second pole member and the armature upon energization of the coil, weakening the magnetic flux and therefore expediting the armature movement by the coil flux to thereby improve repsonse sensitivity.

The wire holding block includes a wire holding portion in which a holding hole for transmitting the electric wire from the rear side thereof and holding the electric wire is formed and a reception groove for receiving the U-shaped blade of the connection terminal. The U-shaped blade of the connection terminal includes a core pressing blade having a step-shaped slit with two different widths in the vertical direction and a wire holding blade having a step-shaped slit with two different widths in the vertical direction, sequentially from the inside in an electric wire insertion direction. Adapting to the outer shape of an electric wire, the electric wire can be held with a wire holding slit (upper step portion) 53a or a wire holding slit (lower step portion) 53b.
