Abstract
The utility model discloses a switch terminal socket. The utility model is characterized in that a circuit board is arranged in a plastic insulation base body, one end of two input ends of the circuit board is connected with a voltage stabilizing tube and a resistor, and then is connected with an input end of a light isolating chip, the other end of the two input ends of the circuit board is connected with the other input end of the light isolation chip through the resistor, and a diode is also connected between the two input ends of the light isolation chip; one end of two output ends of the light isolation chip is connected with an output end of the circuit board and the other end of the two output ends of the light isolation chip is connected with the other output end of the circuit board after passing through the diode. The utility model can automatically convert external strong electrical signals into weak electrical signals. The utility model with the advantages of novel structure, reliable performance and cheap price is a new product in urgent need for the electric power system.
Description
The utility model relates to a kind of junction block that is used for electric wiring.
Usually need Signal Spacing and conversion in technical fields such as the automation of electric power system, Industry Control, at present domestic junction block that also can not realize the automatic conversion of signal strong, weak electricity.
The purpose of this utility model is to provide a kind of switching value junction block, when it can make outside forceful electric power signal by this junction block, converts the weak electric signal of isolation automatically to.
The technical solution of the utility model is achieved in that a kind of switching value junction block, it comprises the plastic insulation pedestal, be arranged on the dividing plate in the plastic insulation pedestal and connect the electric-conductor of input, output respectively, and the cover cap that matches with the plastic insulation pedestal, it is characterized in that: a circuit board is set in the plastic insulation pedestal, be connected with the input of light behind one termination, one voltage-stabiliser tube of two inputs of this circuit board and the resistance every chip, its other end is connected with light another input every chip by resistance, and light also is connected to a diode every between two inputs of chip; Light is every an output of a termination circuit plate of two outputs of chip, and its other end is by another output of connection circuit plate behind the diode; Two inputs of circuit board, output connect electric-conductor respectively.
The utility model is owing to adopt the Darlington to manage the photoelectric isolated chip of the way of output as main circuit, can be outside forceful electric power conversion of signals weak electric signal automatically, through test, the utility model can bear 50Hz between input and output, 3000KV lasts the alternating voltage of 1min, output can be for a long time by the electric current of 60mA, and can suppress high-frequency interferencing signal, and novel structure, dependable performance, cheap are the new products that electric power system is badly in need of.
