Detailed Description
The utility model is described in further detail below with reference to fig. 1-2.
The embodiment of the utility model discloses a fixing structure with a temperature sensor and an outer sleeve not easy to separate, which comprises a lead 1 and a sensing chip 2 arranged on the lead 1 and used for detecting temperature, wherein the sensing chip 2 is a common ntc thermistor in the market, a pin is welded on the sensing chip 2, the pin on the sensing chip 2 is connected with the lead 1 through welding, and when the fixing structure works, the sensing chip 2 senses temperature change and then converts the temperature change into an electric signal to be transmitted to an electric instrument through the lead 1, and the electric instrument converts the electric signal into a temperature value. The sensing chip 2 is sleeved with the heat shrinkage tube 5, an operator is sleeved with the heat shrinkage tube 5 on the sensing chip 2 and then heats the heat shrinkage tube 5, so that the sensing chip 2 is wrapped by the heat shrinkage tube 5 in a shrinkage manner, and the heat shrinkage tube 5 can protect the sensing chip 2.
Referring to fig. 1 and 2, a protective jacket 3 is sleeved on a wire 1, a sensing chip 2 is positioned in the protective jacket 3, an epoxy resin layer 6 is arranged between the protective jacket 3 and a heat shrinkage tube 5, an operator fills epoxy resin into the protective jacket 3, then the sensing chip 2 is placed in the protective jacket 3, and the epoxy resin layer 6 can be formed after the epoxy resin is solidified; the excellent physical and mechanical and electrical insulation properties of the epoxy resin, the adhesion properties with various materials, and the flexibility of its use process are not possessed by other thermosetting plastics, and the epoxy resin can improve the heat conduction efficiency, thereby improving the reaction sensitivity of the sensing chip 2.
Referring to fig. 1 and 2, a fixing sleeve 4 is sleeved on a wire 1, a glue layer is arranged between the fixing sleeve 4 and the wire 1, the glue layer is a polyurethane glue layer, and polyurethane can well adapt to the soft characteristic of the wire 1; the side wall of one end of the fixing sleeve 4, which is close to the sensing chip 2, is integrally formed with two elastic clamping blocks 41, and in the embodiment, the number of the elastic clamping blocks 41 on the lead 1 is two; the inner wall of the protective jacket 3 is provided with two clamping grooves, the two elastic clamping blocks 41 correspond to the positions of the two clamping grooves, and the elastic clamping blocks 41 are matched with the clamping grooves in a clamping way. When the operator places the sensing chip 2 into the protective outer sleeve 3, the elastic clamping block 41 is clamped in the clamping groove, so that the connection stability between the sensing chip 2 and the protective outer sleeve 3 can be greatly improved, and the condition that the sensing chip 2 is separated from the protective outer sleeve 3 is avoided.
