摘要： PURPOSE:To reduce the size of a controlling board, etc., by disposing a reset lever for reversing and resetting a reverse spring and an adjusting dial for adjusting the performing position of a release lever through an adjusting link at the upper end of a case in parallel relationship. CONSTITUTION:On a side of a heat element 1 disposed correspondingly to a three-phase main circuit is provided a reverse mechanism part 90 comprising a reverse spring 9 formed of a flat spring and adapted to move reversely, and a release lever 3 axially supported by an adjusting link 8. A contact mechanism part 65 driven by the reverse spring 9 is installed on the upper part of the heat element 1, and a reset lever 5 for reversing and resetting the reverse spring 9, and an adjusting dial 4 for adjusting the performing position of a release lever 3 through the adjusting link 8 are disposed on the upper face of a case in parallel relationship, and installation of only a reverse mechanism part 90 on the side of the heat element 1 enables the size of the breadth of a thermal type overload relay to be reduced. Since the size of the breadth of the thermal type overload relay does not exceed that of the width of an electromagnetic contactor, these apparatus can be highly densitied to be contained in a controlling board or the like and thus the controlling board or the like can be made smaller.

摘要： PROBLEM TO BE SOLVED: To allow no burning accident of a relay even when in a state where overcurrent keeps flowing in the heat element of the relay, lessen the number of parts, and improve assembling performance. SOLUTION: A heat element 8 is made of a resistance heating plate in a non-bound state of strip thin plates, one part or all of length in a longitudinal direction is arranged along the face of a bimetal, and a length range in the longitudinal direction where the temperature of the heat element 8 becomes highest is processed into a bound state. At least one point in the length range in the longitudinal direction in the bound state is joined with the bimetal 1 so as to integrate with the bimetal 1, and a relative position to the bimetal 1 is immovably held so as to stabilize temperature rise to heighten the operation reliability of a relay. When two or more of joining points are provided, non- joining portions 8E having deflection are formed between the joining points so that the bimetal 1 can be freely bent.

摘要： PURPOSE:To provide possibility of easily offering a relay embodied in different contact constitution or combination comprising small width and height of cases by coupling a main and an aux. case which dividedly accommodate the mechanism part of contacts and opening/closing, and thereby forming a thermal type over-load relay. CONSTITUTION:When an aux. case 201 is combined with a main case 101 through engaging of detent projections 101a, 101b with detaining holes 202a, 202b, the tip of a slider 109 comes into the aux. case 201 to push a movable contact piece 207b to the position as shown by the dot-and-dash line, and a movable contact 206b in contact with a fixed contact 204b is separated to put it in the a-contact state. At this time, another fixed contact 204a and the fixed contact 206b remain in the b-contact state as they have been. If now an over- current flows through a heat element 102, an opening/closing mechanism is actuated to put a slider 109 into movement, and a prong 109a separates a contact 206a from the fixed contact 204a while another prong 109b returns to its original position, and now the movable contact 206b contacts the fixed contact 204b. Thus opening and closing of the contacts are performed.

摘要： PURPOSE:To eliminate the effect of gravity to a moving part when an electromagnetic contactor is mounted on a floor surface or a ceiling surface. CONSTITUTION:The non-moving side end part of a back spring 11 giving return force to a moving part such as a moving iron core 3 or a contact support 5 is supported by a seat 13 moving in the axial direction of the back spring 11 by operating an adjustment cam 14, and the set length of the back spring 11 is thus made variable. The load force of the back spring 11 can be adjusted to the case of mounting a normal vertical surface by operating the adjustment cam 14 even when a floor surface is to be mounted, for which the gravity to the moving part works against the back spring 11, or when a ceiling surface is used to mount, in which, on contrary, the gravity works in the same direction as the force of the back spring 11, and there may be no need for replacing the back spring 11 according to the aposture of mounting.
