On body, and the fairlead connected with the accommodating cavity.The lead of temperature sensor can be led to by fairlead during winding displacement accommodating
Outside chamber, so that temperature sensors are connected with external electrical components.
Preferably, effectively to discharge lead in order, effectively lead is led to outside drilling, described measuring staff body edge
Winding displacement groove is provided with its length direction, the winding displacement groove is connected with fairlead.
As the another embodiment of above-mentioned technical proposal, described bus-bar construction includes being separately positioned on measuring staff body
The pin end of internal thread one end and the female joint of this extracorporeal thread of measuring staff one end, described pin end and female joint are and accommodating cavity
The lead electrical connection of interior temperature sensor, when two neighboring measuring staff body is connected by internal thread and external screw thread, described public access
Head and female joint coordinate contact.The lead of temperature sensor effectively can be hidden in measuring staff body using pin end and female joint
Interior so that measuring staff is more attractive, outward appearance is more succinct, installs more convenient.
Preferably, described pin end is spring, described female joint is conductive spacer.Can effectively it be protected using spring
Demonstrate,prove the contact between pin end and female joint, it is to avoid open circuit is formed between pin end and female joint.
Beneficial effect：Temperature sensor is arranged in measuring staff body in the application, temperature sensor is effectively prevent and exists
Damage during installation, measuring staff body not only acts as supporting role, and temperature sensor formation is protected；In addition, being surveyed some
Bar body connects to form temperature measuring staff, easy for installation, can be connected according to the measuring staff body of the specifically chosen varying number of demand, shape
It is easy for installation into the temperature measuring staff of different length, do not limited by tunnel small space.
