Description

TECHNICAL FIELD

[0001] The utility model belongs to NTC support technical field, concretely relates to a NTC support of flexible abutment. BACKGROUND

[0002] The NTC support is a structure for fixing and supporting NTC (negative temperature coefficient) thermistors, which is usually made of insulating materials. Its main function is to fix the NTC thermistor at a specific position to ensure its stable operation in the circuit. It can provide mechanical support to prevent the thermistor from displacement or damage when subjected to external force or vibration, and also play the role of insulation and protection to avoid short circuit between the thermistor and other components.

[0003] The structure of the NTC support is generally simple, and the common shapes are sheet, column and the like. It usually has specific mounting holes or clamping grooves to facilitate its fixation on the circuit board or other equipment by screws, buckles and the like. The NTC support undertakes the key task of supporting NTC thermistors and other components. However, different electronic devices have great differences in the specification requirements of components, and the types of components are various and the weights are not the same. When the NTC support is used to support these components with different specifications, the adaptability problem will be highlighted. Some heavy components are difficult for the support to bear their gravity after being installed on the NTC support with limited bearing capacity, resulting in great stress at the butt joint part of the support. Under the combined action of gravity and vibration generated during equipment operation and other external forces, the NTC support is prone to bending or even folding. The bending and folding of the NTC support not only changes the original installation position of the NTC thermistor and other components, causing deviation in temperature sensing and reducing the accuracy of temperature measurement and control, but also may cause loose connection between the components and the circuit, leading to poor contact and other problems.
