摘要： PURPOSE:To facilitate an interchange of termianl positions and the increase of capacity of a relay and to prevent generation of chips during assembly by enabling a fixed contact spring and a movable contact spring which constitute the relay to be replaced by each other. CONSTITUTION:A relay is provided with a coil 12 wound around a bobbin 6 and a U-shaped iron core 13 passed through the coil 12 and a contact 15 opposite to the end face of the iron core 13 is freely rockingly fixed to to the end of the iron core 13 via a movable contact spring 16. A fixed contact 19 is secured to a make-side fixed contact spring 3 and a fixed contact 20 is secured to a break-side fixed contact spring 4 and the springs 3, 4 are inserted from one side into a pair of respective support grooves 61 provided in the front face of the bobbin 6 and are fixed to the bobbin 6 by rectangular holes 62 provided in the respective bottoms of the grooves 61. The positions of make- side and break-side extension terminals can thus be interchanged by replacement of the spring 4.

摘要： PURPOSE:To provide a low operating noise electromagnetic relay, assembled in acoustic system and no-vehicle equipment, which shuts off noise arising in operation recovery restoration without conveying to the outside by lowering noise released via a base and through a cover. CONSTITUTION:An electromagnetic relay mainframe 2 is housed in a container which consists of a base 1 and a cover 5. An electromagnetic relay comprises the cover 5 formed of resin, inside which a metal plate 51 is buried and the opening of which is insertedly fitted to the base 1. The middle portions of lead terminals 4 which are attached to the electromagnetic relay mainframe 2 are fixed to the base 1, and the electromagnetic relay mainframe 2 is constructed to float over the base 1.

摘要： PURPOSE:To reduce a shock generated when a moving contact is brought into contact with a fixed contact by eliminating armatures, and limiting the shock sound generating source to contacts only. CONSTITUTION:When driving voltage is applied to a solenoid coil 42, a plunger 51 is magnetized and moved to a fixed contact terminal 62 side, and a moving contact 61 is pushed to a fixed terminal 63. A moving contact terminal 64 is connected to the other end of the plunger 51 via a plate spring 52, and the terminal 62 and terminal 64 are closed when the moving contact 61 is pressed to the fixed contact 63. When the driving voltage is cut off, the plunger 51 is recovered by the action of the plate spring 52, and the closed terminal 62 and terminal 64 are opened. Armatures are eliminated, and the shock sound generating source can be limited only to contacts. The moving speed of the plunger 51 moving in a hollow bobbin 41 is nearly constant, and the shock generated when the contact 61 is brought into contact with the contact 63 can be reduced.

摘要： PURPOSE:To balance the contact pressure at the contact position and to realize a long service life of an electromagnetic relay by shifting each other the positions of two projections in the axial direction of a movable spring where a force is applied to the movable spring. CONSTITUTION:Since a card 6 linking to an armature 3 makes a rotating movement as well as a reciprocating movement, the first projection 6-2 moves in the direction to a movable contact 7-1 as well as in the direction to push a movable spring 7. On the other hand, the second projection 6-3 moves in the reverse direction to the movable contact 7-1 as well as in the direction to push the movable spring 7. In this case, the first projection 6-2 of the two projections is arranged to shift to separate from the movable contact 7-1 in the axial direction of the movable spring, to the second projection 6-3, shifting each other. As a result, the positions of the first projection 6-2 and the second projection 6-3 where the force is applied to the movable spring 7 can be made coincident. Consequently, the contact pressure at the contact position is balanced, and a long service life can be realized.

摘要： PURPOSE:To improve the productivity of magnetic heads by setting the head gap length according to the recess part formed vertically on the head gap forming surface. CONSTITUTION:An R/W head gap 33 and an erasion head gap 35 has the prescribed length decided by a pair of bottomed holes (recess parts) 37 and another pair of bottomed holes (recess parts) 38 formed vertically on the head gap forming surface (upper side surface) respectively. It is possible to form those bottomed holes at a time. Thus the conventional forming processes are decreased and furthermore the positioning accuracy can be secured extremely easily when an R/W core bar is put together with an erasion core bar via a glass adhesive layer 36. In addition, each bottom hole has no fragile sharp end. This eliminates the defective products caused by a conventional process to form a triangular groove.
