摘要： Peripheral surfaces of end portions of individual optical fibers constituting a first optical fiber array are in close contact with an optical fiber fitting surface of a base, while the peripheral surfaces of the end portions of the individual optical fibers are in close contact with one another. Peripheral surfaces of end portions of optical fibers on both sides out of the individual optical fibers constituting the first optical fiber array are in close contact with a pair of stopper members, respectively, disposed on both sides of an end portion of the first optical fiber array. A second optical fiber or optical fiber array is opposed to an end face of the end portion of the first optical fiber array. Between projecting portions of the pair of stopper members projected from the end face of the first optical fiber array, peripheral surfaces of end portions of the individual optical fibers constituting the second optical fiber or optical fiber array are in close contact with the optical fiber fitting surface of the base.

摘要： A polarized relay with an electromagnetic drive comprises an electromagnetic yoke composed of a core wound with a coil and a yoke body, and having one end portion of one magnetic polarity and a pair of bifurcated end portions of the other magnetic polarity opposite to the one magnetic polarity. The bifurcated end portions are separated in opposition from each other. The one end portion of the yoke is disposed between the bifurcated end portions so as to cooperate to form a pair of working gaps. A movable block of a substantially C-like configuration incorporating a permanent magnet has two magnetic pole pieces which are disposed within the working gaps, respectively. Guide is provided for guiding the movable block in response to energization and deenergization of the coil so that the pole pieces are movable within the respective working gaps. A contact mechanism including movable contacts is mechanically coupled to the movable block to make or break circuit.

摘要： An electromagnetic contactor according to the present invention is so constructed that the electromagnetic device and the fixed point of contact are fixedly fitted into a casing which is divisible in the direction along the moving direction of a polar contact. Moreover, a bottom casing with a screw mounting hole is fitted in the outer peripheral portion at the lower end of the casing. Therefore, the rigidity of the casing as a whole is enhanced, and at the same time the working characteristics can be prevented from being changed when the screw is mounted. Furthermore, the positioning accuracy of the electromagnetic device relative to the fixed point of contact is determined only by the dimensional accuracy of the casing and the electromagnetic device, and by the position accuracy of the fixed point of contact. The contact pressure is improved to be stable.

摘要： An electromagnetic relay includes an electromagnet, an armature assembly opposed to the electromagnet which moves according to the selective energization of the electromagnet, a contact mechanism which operates according to the movement of the armature assembly, and a pair of sheet springs which support the armature assembly so that it can reciprocate along its direction of motion. Thus, because the biasing force characteristic curve may be altered by altering the spring forces and characteristics of either or both of the sheet springs, it is possible to greatly expand the possible range and variety of adjustment of the relay, as opposed to the case in which only one sheet spring is used. The two sheet springs may optionally be mounted one on either side of the armature assembly, with respect to its direction of motion. And, optionally, a first one of the sheet springs is coupled to the armature assembly by its central portion and to a fixed member by its two end portions, while a second one of the sheet springs is coupled to the armature assembly by its two end portions and to a fixed member by its central portion. The fixing of the springs to the armature assembly and/or to the fixed members may either be loose, sliding, turning, or cantilever type; each has its benefits in terms of preventing wobbling of the armature assembly. The armature assembly may be provided with guide feet for keeping its motion rectilinear and orthogonal to the longitudinal direction of the electromagnet.

摘要： A polarized electromagnetic relay apparatus for assembling a coil spool with a terminal carrying base plate is disclosed. The coil spool assembly has a front collar with a projecting piece. The projecting piece is adapted to engage with a latch hole in the terminal carrying base plate. The terminal carrying base plate has jaw-like, offset portions which engage with supporting offset portions formed in the rear collar of the coil spool assembly. The flexible projecting pieces may be of deformable material in order to easily engage with the latch hole of the base plate. The flexible projecting pieces can be tapered, also to facilitate engagement with the base plate latch hole. A terminal holder is formed on the rear collar of the coil spool assembly and is adapted to receive terminals from the coil. The terminal holder comprises the supporting offset portions which engage with the jaw-like offset portions of the base plate. The terminal holder is of a greater thickness than the base plate.
