Reed switch relay with protective cover

Abstract

The invention discloses a reed switch relay with a protective cover, and belongs to the field of relays. The invention discloses the reed switch relay with the protective cover. The reed switch relaycomprises the following parts: a wiring base; a pin seat arranged on the wiring base, and a terminal of the pin seat inserted into a terminal hole of the wiring base; an electromagnetic coil arrangedon the pin seat; a reed switch arranged on the pin seat, wherein one end of the reed switch is electrically connected to the terminal of the pin seat, and the other end of the reed switch is connectedwith an external circuit; magnetic conductive sheets arranged at the two ends of the electromagnetic coil, wherein magnetic poles of the magnetic conductive sheets are close to the reed switch; the waterproof protective cover clamped on the wiring base through a clamping piece; after the electromagnetic coil on the pin seat is powered on, magnetic fields are generated at the two ends of a siliconsteel sheet in a coil framework and guided into the eight magnetic poles on the two sides of the coil through the magnetic conductive sheets; the magnetic conductive sheet is a high-magnetic-conductivity pure iron sheet and attracts magnetic materials in the reed switch, the reed switch is switched on, and the control purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a reed switch relay with a protective cover. Background technique [0002] The reed switch relay with a protective cover plays a very important role in the control of rail transit signals. The products used in the environment, with the rise and large-scale application of rail transit, signal control of various intensities of rail transit equipment It has become a problem that needs to be faced seriously. In the industry, imported products such as Yaskawa from Japan are mostly used, but their cost is expensive and the channels are uncontrollable. In the face of the national rail transit strategy, it is necessary to have similar products with high performance and high reliability made in China. An important topic in the domestic industry, especially for the harsh environment of rail transit signal control, a dry reed with a protective cover with fast response time, high sensitivity,...

[0002] The reed switch relay with a protective cover plays a very important role in the control of rail transit signals. The products used in the environment, with the rise and large-scale application of rail transit, control the signals of various intensities of rail transit equipment. It has become a problem that needs to be faced seriously. In the industry, imported products such as Yaskawa from Japan are mostly used, but their cost is expensive and the channels are uncontrollable. In the face of the national rail transit strategy, it is necessary to have domestically produced similar products with high performance and high reliability. An important issue in the domestic industry, especially for the harsh environment of rail transit signal control, a dry reed with a protective cover with fast response time, high sensitivity, long service life, and high reliability is suitable for harsh environments Tube relays are very important
