Relays with increased control sensitivity

Abstract

The invention discloses a relay with the control sensitivity improving function. Double metal pieces are provided with a fixing frame and supporting frames. The supporting frames are connected with the double metal pieces. A guide plate is arranged in a sliding groove and sinks inwards to form grooves. The double metal pieces are arranged in the grooves. Resistance wires are arranged between the double metal pieces and connected with the double metal pieces. The guide plate is connected with an ejector rod which is connected with compensation double metal pieces. The compensation double metal pieces are connected with a push rod which is connected with a connecting rod. The push rod is connected with a leaf spring which is connected with a movable contact, an arch spring and a manual reset button. A reset regulating screw is arranged between the compensation double metal pieces and the movable contact. According to the relay, the buffer spring is arranged to prevent the metal pieces from impacting the fixing frame, and thus the structure of the relay is prevented from being damaged. Meanwhile, the ends of the metal pieces are fixed, so that the metal pieces deform and move more accurately, control over sensitivity is facilitated, and the relay can work stably.

Description

technical field [0001] The invention relates to a relay, in particular to a relay with the function of increasing control sensitivity. Background technique [0002] Relay, also known as electric relay, is an electronic control device, which has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it is actually used in smaller A kind of "automatic switch" that controls the larger current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. The relay coil is represented by a rectangular box symbol in the circuit. If the relay has two coils, draw two parallel rectangular boxes. At the same time, mark the text symbol "J" of the relay in the rectangular box or beside the rectangular box. There are two ways to represent the contacts of the relay: one is to draw them directly on the side of the rectangular box, which is more i...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the above-mentioned existing relay processing reaction time is slow, the heat generation inside the computer cannot be cut off and processed in time, and the components are easily bumped and loosened when the components move, so that the structure of the relay is damaged. A relay with the function of increasing control sensitivity. The relay prevents the impact of the metal sheet and the fixed frame by setting a buffer spring to prevent the structure of the relay from being damaged. At the same time, the end of the metal sheet is fixed to make the metal sheet deform and move more easily Accurate, easy to control the sensitivity, so that the work of the relay can be stable, which solves the problem that the existing relay has a slow processing response time, cannot cut off and deal with the heating inside the computer in time, and is easy to cause impact and looseness when the components move, making the relay The problem of damage to the structure of the
