A gel plastic encapsulated miniature solid state relay

Abstract

The invention discloses a gel plastic-package miniature solid relay. The gel plastic-package miniature solid relay comprises a shell, wherein a terminal is arranged on an outer surface of a lower endof the shell in a penetrating way, a gel block and a circuit board are arranged at a position, near to an upper end, of an inner surface of the shell, the gel block is arranged at an upper side of thecircuit board, the circuit board is fixedly connected with the gel block, a terminal is fixedly connected with an outer surface of a lower end of the circuit board, a rubber ring is arranged at a position, near to the rubber block, of an outer surface of the upper end of the shell, first sleeves are fixedly connected with surrounding corners of the outer surface of the upper end of the shell, second sleeves are arranged on outer surfaces of upper ends of the first sleeves, and springs are arranged in the first sleeves and the second sleeves. The gel plastic-package miniature solid relay can have a function of vibration reduction, the device maintenance efficiency is effectively improved, moisture is prevented from being stayed on the outer surface of the shell, the corrosion and the damage to the shell are reduced, and the service lifetime of the device is prolonged.

Description

technical field [0001] The invention relates to the field of relays, in particular to a gel plastic encapsulated miniature solid state relay. Background technique [0002] Due to the development of digitization, multimedia, microelectronics, optoelectronics and power electronics technology, the speed of information processed by corresponding complete machines and systems, such as various communication and network switching equipment, optical communication and its transmission system, remote control and telemetry systems, etc. The faster, the greater the amount of information, and more and more channels. Solid state relays are widely used in military, industrial and household appliances. The development of communication, remote control, and telemetry plays an important role. Traditional solid state relays are small in size during use, and users can easily drop them during installation, causing the terminals to collide with the ground or collide with other objects to cause dam...

[0002] Due to the development of digitization, multimedia, microelectronics, optoelectronics and power electronics technology, the speed of information processed by corresponding complete machines and systems, such as various communication and network switching equipment, optical communication and its transmission system, remote control and telemetry systems, etc. The faster, the greater the amount of information, and more and more channels. Solid state relays are widely used in military, industrial and household appliances. The development of communication, remote control, and telemetry plays an important role. Traditional solid state relays are small in size during use, and users can easily drop them during installation, causing the terminals to collide with the ground or collide with other objects to cause damage. It is distorted and deformed. At the same time, a large amount of heat will be generated during the conductive operation of the solid state relay, and it is difficult to dissipate heat in time. After a long time of use, the aging and damage of the device will be accelerated. Use will corrode the shell and reduce its service life
