There are two common ways to connect solder pins and signal wires: 1. Solder the signal wires and solder pins, and then cover the connecting parts with heat-shrinkable tubes. This method has low assembly efficiency and uneven assembly quality; Second, install metal socket terminals and plastic connectors on the signal lines, and then insert them with solder pins. Although the method of soldering the original signal lines and solder pins and then covering the connection parts with heat-shrinkable tubes improves the assembly efficiency and assembly quality, but the process is more complicated, adding parts such as metal connector terminals, and it is difficult to realize automatic production

The invention discloses a connecting structure for voltage input of a relay coil, and a processing method of the connecting structure. The connecting structure comprises the relay coil and a signal line, wherein the relay coil comprises a coil frame and a solenoid wound on the coil frame; and the signal line extends into the relay coil, is connected with lead wires at both ends of the solenoid, and is fixed to the coil frame. According to the connecting structure for voltage input of the relay coil, the signal line is directly led out from the interior of the relay coil, the structure is simple and stable, the strength of a connecting part of the relay coil and the signal line is ensured, the adoption of components such as metal plug-in terminals and heat shrinkable tubes is reduced, the production cost is decreased, and the automatic production is facilitated.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a connection structure for voltage input of a relay coil and a processing method thereof. Background technique [0002] The magnetic latching relay is a new type of relay. With the development of the electric energy meter, the magnetic latching relay has become an indispensable and important part of the electric energy meter. Most of the lead-out ends of the existing magnetic latching relay coils are welding pins, which are then connected to the welding pins through signal lines, and then connected to the circuit. There are two common ways to connect solder pins and signal wires: 1. Solder the signal wires and solder pins, and then cover the connecting parts with heat-shrinkable tubes. This method has low assembly efficiency and uneven assembly quality; Second, install metal socket terminals and plastic connectors on the signal lines, and then insert them with so...
