However, since the outer casing is made of plastic, the process of combining the sealing groove of the coil bobbin with the outer casing and soldering brings a lot of trouble to the manufacture of the product, especially after the internal components are installed, the coil bobbin is often sealed. When the glue tank and the shell are packaged, the high temperature causes the shell to expand, just like the bulge at the bottom of the thermos liner, which affects the appearance of the product
At the same time, when the relay is working, the current can be close to 15A when it is closed. However, due to the short distance between the two poles of this relay, when the relay is under too high pressure, an arc will also be generated in the shell, which will increase a lot of heat and affect the relay. usage time

Abstract
The invention discloses a switching relay processing method. The system according to the method comprises an external shell (1), a moving contact lead-out pin (2), a normally-open contact lead-out pin(3), a normally-closed contact lead-out pin (4), a coil lead-out pin 1 (5), a coil lead-out pin 2 (6) and a coil bobbin (7). The coil bobbin (7) is provided with a sealing glue slot (7-3) and an ironcore hole (7-2). The integrally formed coil bobbin is arranged in the external shell, and the integrally formed coil bobbin and the shell are reinforced by using the epoxy resin glue through the ironcore hole. The periphery of the sealing glue slot of the coil bobbin and the external shell are sealed by the epoxy resin glue, the temperature can be 120 DEG C and the hot air is discharged throughthe ventilation hole so that damage of the hot air to the external shell can be reduced, the conventional processing tool does not need to be improved or replaced, the technology process can be simplified and the production efficiency can be enhanced.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, and specifically relates to a processing method for a switching relay. Background technique [0002] A relay is an electronic control device, which has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is usually used in an automatic control circuit. In fact, a smaller current is used to control a larger current A kind of "automatic switch". In the circuit, it plays the role of automatic adjustment, safety protection, conversion circuit, etc., and is widely used. In particular, a switching relay is not only resistant to high voltage, but also has high sensitivity. It is a commonly used relay in the field of industrial circuit boards. However, since the outer casing is made of plastic, the process of combining the sealing groove of the coil bobbin with the outer casing and soldering brings a lot of trouble to the manufac...
