Abstract
The utility model relates to a temperature sensor connector which comprises a thermal resistor, a metal casing and two temperature signal lines. The thermal resistor is connected with two contact pins through the two temperature signal lines; the two contact pins are welded with a groove-shaped base, which forms a connector assembly; the two temperature signal lines and the thermal resistor are poured in the metal casing through epoxy resin; the two contact pins and the groove-shaped base are fixed at the upper part of the metal outer casing through epoxy resin; the metal casing is a tapered step shaft which is bigger at the top part; the upper section of the shaft of the metal outer casing adopts a hexangular surface; pipe taper threads are formed at the middle section of the shaft of the metal casing; the thermal resistor is positioned at the bottom part of the lower section of the shaft of the metal outer casing; and a sealing groove is formed at a shaft shoulder between the upper and the middle sections of the metal casing. The utility model has the advantages of convenient assembly and disassembly and good sealing performance.
Description
Technical field
The utility model relates to a kind of temperature sensor joint, belongs to the temperature sensor technical field.
Background technology
Temperature sensor mainly by thermistor, play induction and the metal shell of protective effect and the temperature signal line of unofficial biography signal constitute; thermistor is arranged in the metal shell and changes with the induction water temperature; with the resistance value output that thermistor changes, realize temperature control by the temperature signal line.But temperature sensor does not dispose the installation bayonet socket usually, therefore when temperature sensor is installed in monitoring location, operates comparatively loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides a kind of easy to loading and unloading, the temperature sensor joint of good airproof performance.
The utility model for the technical scheme that achieves the above object is: a kind of temperature sensor joint, comprise thermistor, metal shell and two temperatures signal wire, it is characterized in that: described thermistor is connected with two contact pins by the two temperatures signal wire, two contact pins and the welding of flute profile base constitute connector, two temperatures signal wire and thermistor use poured with epoxy resin in metal shell, two contact pins and flute profile base are fixed on the top of metal shell by epoxy resin, metal shell is up big and down small step axle, shaft part has Six Point on the metal shell, middle shaft part has the pipe taper thread, thermistor is positioned at the bottom of shaft part under the metal shell, and the shaft shoulder place on the metal shell between the middle shaft part is provided with seal groove.
The utility model constitutes connector with two contact pins and the welding of flute profile base, and contact pin is connected with thermistor by the two temperatures signal wire, therefore can be connected reliably by the plug-in unit that this connector and another match, to control circuit input temp signal.Shaft part adopts the pipe taper thread in the metal shell of the present utility model, can not only conveniently spin and be installed in the measured position, and can also reach the effect of sealing by the pipe taper thread, and can directly the temperature sensor joint be equipped with liquid medium or gas medium measured position, directly contact with medium.The utility model adopts connector to be connected with control circuit, and is connected with pipeline by the pipe taper thread, loads and unloads very easy to use.
