The invention relates to a U-shaped spring fixing sheet of a balance force type sealed relay and the balance force type sealed relay. The U-shaped spring fixing sheet comprises a sheet-shaped body, and the body is provided with clamping grooves matched with two clamping parts on a lower portion of a U-shaped spring and a welding part used for welding a conversion pin. Each clamping groove is located in one end of the body. A length direction of each clamping groove is arranged along a first direction, the welding part is perpendicularly arranged on the body, the length direction of the weldingpart is arranged along a second direction, the second direction is perpendicular to the first directionso that a welding surface perpendicular to each clamping groove is formed on the welding part.Aproblem that a position size of each clamping groove of an existing U-shaped spring fixing sheet in an X direction cannot meet a product requirement is solved.
Description
technical field [0001] The invention relates to the technical field of electromagnetic relay manufacturing, in particular to a U-shaped spring fixing piece of a balanced force sealed relay and a balanced force sealed relay. Background technique [0002] The balanced force sealed relay has the same armature holding force and contact pressure in the excited and de-energized state, so it has excellent environmental resistance and mechanical properties, and is widely used in the aerospace field. [0003] The structure of an existing balanced force type sealed relay is as attached in the patent with the notification number CN201319355Y figure 1 Because the armature structure on the magnetic circuit system is a seesaw structure that rotates around the axis, the connection between the switching pin on the contact system and the moving reed on the armature structure generally uses a U-shaped spring to achieve soft connection. Under good contact conditions, there will be no obvious ...
