The technical solution of the present invention is described below with reference to the accompanying drawings and examples.
As shown in fig. 1, the insulation packaging supporting structure of a temperature sensing head according to the present invention comprises a body 1 having a certain length, wherein N partition plates 2 are disposed on the body 1, N is an even number greater than 3, and the N partition plates 2 are equiangularly spaced along an outer edge of the body 1; the outer end of the partition plate 2 is provided with two support sheets 3, and the two support sheets 3 symmetrically extend to two sides of the partition plate 2 to form a Y-shaped integrated structure with the partition plate; the partition panels 2 distributed at equal angles divide the inner cavity of the sensor, two adjacent partition panels 2 and two opposite support sheets 3 on the partition panels 2 form an open clamping structure, an independent channel cavity is formed in the inner cavity of the sensor, the N partition panels 2, the support sheets 3 on the N partition panels 2 and the body 1 form a cylinder with an approximate snowflake-shaped cross section, the support sheets 3 are abutted against the inner wall of the sensor and keep certain elastic friction force, the thermistor and a welding spot are arranged in the middle to form positioning, a pin lead of the thermistor and the welding spot of the pin lead penetrate through the channel cavity to form clamping and positioning, intervals are formed between the welding spots and between the welding spot and the metal inner wall of the sensor, and the sensor can be ensured to have enough electrical insulation by subsequent sealant injection.
The vertical projections of the outer end surfaces of the support pieces 3 on the N partition panels 2 are positioned on the same circumference, and the included angle between the two support pieces 3 on the same partition panel 2 is larger than 90 degrees; the two supporting pieces 3 on the same partition plate 2 are opened towards two sides to form supporting connection with the inner wall of the sensor, and the opened supporting pieces 3 can provide higher friction force to avoid the displacement problem during the subsequent injection of the sealing glue; and two opposite support sheets 3 on the adjacent partition plates 2 can clamp the outer sides of welding points, so that the welding points are prevented from being too close to the inner wall of the sensor, and the electrical insulation performance of the sensor is improved.
