Double sensor adaptive structure

Abstract

The invention relates to the technical field of temperature control sensor, specifically relates to a double sensor adaptive structure. The structure comprises a temperature-sensitive housing and a plastic support, the plastic support is arranged in the temperature-sensitive housing and is matched and connected with the housing, an accommodating frame and a positioning frame are arranged on the upper end surface of the plastic support, a temperature-sensitive component is arranged in the accommodating frame, two fuse links are arranged in the positioning frame, a heat conductive hose clamp is connected between the two fuse links, and the heat conductive hose clamp and the temperature-sensitive component separately contact against a temperature-sensitive surface on the upper end of the temperature-sensitive housing. According to the invention, the structure is reasonable, two fuse links are integrally connected with each other through the conductive hose clamp and are integrally mounted with the temperature-sensitive component on the upper end surface of the plastic bracket, the radial dimension of the sensor can be effectively reduced, the positioning frame and the accommodating frame separately comprises openings of fixed pin to avoid a problem of low assembly efficiency on punching; the assembly efficiency and the automation degree are improved, the heat conductive hose clamp coordinated with the two fuse links maintains simultaneous temperature sensing capacity, so that the sensor acquires better heat sensitivity than before.

Description

technical field [0001] The invention relates to the technical field of temperature control sensors, in particular to a dual sensor adaptation structure. Background technique [0002] In recent years, with the rapid development of plastic materials, they have been replaced in many metal material applications because of their complex processing capabilities, fast efficiency, simultaneous processing of multiple workpieces, and high integration. In the field of plastic materials, with the gradual improvement of the weather resistance of plastic materials, there are more options for use, especially in the field of adaptive structures. [0003] For example, Chinese patent 201510214517.5 in an integrated sensor patent group discloses the structure of multi-functional integrated parts such as adapting thermal components, thermal fuses, trigger mechanisms, switches, anti-dry heating, and PTC, which indicates that the industry is using plastic materials to replace In the past, alumin...

[0003] For example, Chinese patent 201510214517.5 in an integrated sensor patent group discloses the structure of multi-functional integrated parts such as adapting thermal components, thermal fuses, trigger mechanisms, switches, anti-dry heating, and PTC, which indicates that the industry is using plastic materials to replace In the past, aluminum-plated metal materials were used as the beginning of the adaptation structure, but the current sensor structure is set to the action of the outer spring of the bracket, and the action sensitivity is not enough. It is difficult to achieve good contact with the temperature-sensing surface of the thermistor and the fixed position of the fuse. Large; and due to the needs of product installation and shape design, there is an urgent need for a structural design with a smaller size

[0004] Chinese patents 201520625189.3 and 201520625105.6 disclose an adaptation structure in which ceramic pillars are used to fix the thermistor, plastic parts fix the fuse and then lead wires are perforated. The sensitivity is reduced, and the adhesion mode between the ceramic column and the temperature-sensitive aluminum cover is easy to fall off at high temperature and other adverse effects. The lead wire is led out through the perforation, which leads to a decrease in assembly efficiency, and the thermal fuse is only one layer of protection and is prone to failure.
