Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the temperature controller with the integrated polar ring comprises a base 1 and a mounting plate 2, wherein a temperature control assembly 3 is arranged on the mounting plate, a polar ring 4 is arranged on the base, a static contact piece 5 is integrally arranged on the polar ring, and a movable contact piece 6 is arranged on the base and is opposite to the static contact piece. The integrative degree of difficulty that sets up the static contact can reduce later stage assembly on the utmost point circle, and the relative riveted temperature rise of an organic whole between the two is lower moreover, has effectively reduced the cost of manufacturing moreover, and the movable contact can pass through the screw etc. and install on the base, and further can set up the installation boss on the base, passes through the screw with the one end of movable contact and is connected with the installation boss, and the other end corresponds the setting in the static contact below.

The utility model discloses in, as shown in the figure, temperature control assembly includes bimetallic strip 31 and ejector pin 32, bimetallic strip is used for overheated time through the ejector pin promotes the movable contact spring with the static contact separation. The bimetallic strip is heated and deformed to push the ejector rod, and the ejector rod is stressed to push the movable contact piece and the static contact piece to be separated to realize electric breaking.

The utility model discloses in, as shown in the figure, still can dismantle on the base and be connected with clamp plate 7, be equipped with movable groove 72 on the clamp plate, the ejector pin part install in movable inslot. The movable groove on the pressing plate is used for the ejector rod to move after the pressing plate is installed, so that the guiding effect is achieved, and the use is more stable.

The utility model discloses in, as shown in the figure, be equipped with mounting groove 11 on the base, the clamp plate bottom be equipped with mounting groove joint complex boss 71. The pressing plate is installed in a clamping mode, and the pressing plate is convenient to assemble and disassemble.

The utility model discloses in, as shown in the figure, the mounting groove runs through the setting, the static contact passes the mounting groove. In addition, because the integral movable contact piece needs a larger through hole for the static contact piece to pass through, the mounting groove also plays a role, and the structure is more compact.
