Fixing seat for positive temperature coefficient (PTC)-type heater

Abstract

The invention provides a fixing seat for a positive temperature coefficient (PTC)-type heater. The fixing seat comprises a lower base and an upper top plate which can be clamped and fixed in a matching way, wherein a U-shaped groove is formed in the lower base, a strip-shaped through hole is inwards formed in a middle segment along a clamping surface, first connection plates are symmetrically arranged on outer walls of two sides of a lower segment, a limitation rod is arranged on an outer wall of one side of a bottom end, a temperature controller clamping groove is formed in one side of a top surface of the upper top plate, a fuse fixing clamp opening is formed in the other side of the top surface, a second connection plate is arranged at one side of the lower segment, and a limitation hook is arranged at the bottom end and is adaptive to the limitation rod. The fixing seat has the advantages that electrode plates can be prevented from being exposed, the situation that the two electrode plates are touched to cause short circuit can also be prevented, and the safety performance is improved; a circuit is orderly and reasonable to arrange and convenient to assemble and disassemble, and the working efficiency is improved; a temperature controller and a fuse can be respectively connected in series with two circuits connected with the electrode plates, and the application safety is further ensured; and the phenomena that the fixing seat swings leftwards and rightwards and the upper top plate slips off are prevented after the lower base and the upper top plate are clamped, and subsequence connection operation with a plug can be facilitated.

Description

technical field [0001] The invention relates to the technical field of PTC heaters, in particular to a fixing seat for a PTC heater. Background technique [0002] PTC plus heating element has the incomparable advantages of traditional heating elements such as constant temperature heating, no open flame, high heat conversion rate, safety and energy saving, little influence on power supply voltage, and long natural life. It is more and more popular in the application of electric heating appliances. of favor. After the PTC thermistor is powered on, it heats up by itself, and the surface temperature of the PTC thermistor will remain constant when heated at a constant temperature. This temperature is only related to the Curie temperature of the PTC thermistor and the applied voltage, but basically has nothing to do with the ambient temperature. [0003] At present, when the two electrode pieces of the PTC heater are assembled into the market, it is necessary to add a base to the...

Problems solved by technology

[0003] At present, when the two electrode pieces of the PTC heater are assembled into the market, it is necessary to add a base to the electrode pieces of the PTC heater to fix it. However, the existing base is first used for the PTC heater. After fixing, the designed line layout groove is unreasonable, and there are potential safety hazards. Secondly, the line layout operation is difficult, difficult to disassemble and assemble, and time-consuming and laborious
