Abstract

The invention discloses a thermosensitive ceramic heater combination comprising mounting sheet metal. The mounting sheet metal is provided with corresponding mounting holes connected with the whole combination and matching with mounting support fitting holes; the mounting sheet metal is further provided with an insulating positioning junction box. The invention further discloses a heater of the thermosensitive ceramic heater combination, a production process of the heater and a mounting support of the heater. Through the process design wherein heat transfer pipes are subjected to gradual rolling and non-heat conductive faces are subjected to positioning and clamping, and through the structural design of positioning wheels, operational noise of the heater is eliminated. Through the design where incoming and outgoing power leads of the heater are all gathered to the positioning junction box located on the mounting sheet metal, electric connection reliability is improved, and reasonable wiring, electric connection safety and reliability and compact structure are achieved. Meanwhile, the mounting support helps greatly improve connection reliability and application safety of a heating rod and a connecting wire set of the heater. The thermosensitive ceramic heater combination, the heater and the mounting support have the advantages that manufacturing cost is greatly reduced and production efficiency is improved.

Description

technical field [0001] The invention relates to a heater assembly, in particular to a heat-sensitive ceramic heater assembly, heater and mounting bracket thereof. Background technique [0002] The existing technologies are as follows: [0003] A bracket for a PTC heat-sensitive ceramic electric heater and a PTC electric heater (publication number CN201174784), including a mounting surface and a supporting surface, a concave cavity for installing and fixing a heating element is arranged on the supporting surface, and the bottom of the concave cavity is also There is an inwardly extending cavity for placing the wires connected to the lead-out terminals of the heating element, and a lead-out hole is provided on the supporting surface at the bottom of the cavity. A through hole for placing the fuse is provided on one side wall of the supporting surface. [0004] Through this technical solution, the fuse can be combined with the bracket to prevent it from being connected to the...
