The invention discloses a coil and a relay thereof. The coil comprises a coil rack, a coil pin and an enameled wire. The bottom part of the coil rack is provided with a pin inserting hole of which the opening is downward. The upper part of the coil pin is inserted in the pin inserting hole of the coil rack and the upper part of the coil pin is enabled not to appear in the winding window of the coil rack. The side surface of the bottom part of the coil rack is also provided with a lead slot enabling the winding window of the coil rack and the space below the bottom part of the coil rack to be communicated so that the enameled wire connected with the coil pin below the bottom part of the coil rack is enabled to be led to the winding window through the lead slot. The structure of the coil rack is improved so that the length of the coin pin can be greatly reduced, leading of the enameled wire is also facilitated, winding of the enameled wire can be completed after inserting of the coil pin without bending and re-straightening technologies, and the defects of damage and breaking of the enameled wire can be effectively avoided.
Description
technical field [0001] The invention relates to a coil and its relay. Background technique [0002] Relay is an automatic switching element with isolation function, which is widely used in communication, automobile, automatic control, household appliances and other fields, and is one of the most important control elements. [0003] Relays are divided into monostable, bistable, AC, and DC. Different application fields have different requirements for relays with different functions. The bistable relay can keep the relay in the closed or open state without additional power consumption; the AC relay can meet the requirements of the application fields that require AC input. Because with the rapid development of home furnishing and industrial control, the use of relays is increasing, and the cost has become a very important competitiveness; the coil, as the heart of the relay, provides power for the work of the relay, and its quality requirements are high. The cost ratio is larg...
