Small-volume and high-current temperature controller

Abstract

The invention provides a small-volume and high-current temperature controller, which comprises a head cover, a shell, a first terminal, a second terminal, a spring blade, a fixed contact, a movable contact, a ceramic rod, a disc and a seal cover, wherein two terminal installation parts are provided with the first terminal and the second terminal through rivets respectively; the first terminal is in a straight sheet form; the second terminal is in a folded sheet form; the spring blade is in a fan-shaped sheet form; a rectangular clamping part is arranged on the edge of the spring blade; a first contact installation hole is formed in one side edge opposite to the clamping part; the clamping part of the spring blade is clamped between the terminal installation parts of the first terminal and the shell; the movable contact is fixedly connected to the first contact installation hole of the spring blade; the fixed contact is fixedly connected to a contact installation part of the second terminal; the disc is arranged at the lower part of a barrier of the shell; the seal cover is packaged at the bottom part of the shell; the ceramic rod is inserted into a guide hole of the shell and is propped between the center of the spring blade and the disc; and the head cover is arranged at the top part of the shell. The small-volume and high-current temperature controller is small in volume, good in heat dissipation performance and suitable for high-current work places.

Description

technical field [0001] The invention relates to the field of thermostats, in particular to a thermostat with small volume and high current. Background technique [0002] The thermostat has the function of high-temperature power-off protection and is a very important safety product in the electrical field. The current that can be carried is one of the indicators to measure the performance of a thermostat. Generally, a high-current thermostat has a larger volume and a more complicated internal structure, and due to electric heating, it is particularly easy to overheat and burn out during work. On the one hand, this kind of thermostat has poor working stability and is more sensitive to electric heating caused by high current. On the other hand, the complex structure of the thermostat leads to a bulky volume, which makes it difficult to apply to some occasions that require a smaller volume. [0003] It is not difficult to see that there are certain defects in the prior art. ...

The amount of current that can be carried is one of the indicators to measure the performance of a thermostat. Generally, a high-current thermostat has a larger volume and a more complex internal structure, and due to electric heating, it is particularly easy to overheat and burn out during work.

On the one hand, this kind of thermostat has poor working stability and is more sensitive to electric heating caused by high current.

On the other hand, the complex structure of the thermostat leads to a bulky volume, which is difficult to apply to some occasions that require a smaller volume
