Terminal fastening structure of sheath-type platinum resistance thermometer

摘要

The present invention provides a number of terminals (for example, 2, 3, etc.) for connecting a thermocouple wire (nickel wire) drawn from a platinum resistance thermometer and a compensation wire leading to a measuring instrument. 4, 6) to form multiple drill center grooves in the insulating block for the optional processing of bolt through holes, so that one type of insulating block can be applied to various terminals. The structure relates to a plurality of terminals (40) for accommodating the platinum resistance thermometer (T1) and connected with a sheath cable (35) having thermocouple wires (30a, 31a, 32a) and thermocouple wires (30a, 31a, 32a). , 41, 42, insulation having terminal locator grooves 51, 52, 53, 54, 55, 56 for determining the position of the terminals 40, 41, 42 and the lead-out hole 58 in the center Shizuke having a terminal 50 and a terminal accommodating chamber 71 which is opened and closed by a cover 60 and a cover 60 and a sheath cable 35 is installed at a lower portion thereof. The cable connection part 72 is formed and the side part is comprised by the terminal housing 70 which has the lead opening 73 for drawing out the compensation wire 30b, 31b, 32b connected to the terminal 40, 41, 42 to the outside. Drill center grooves 51a, 52a, 53a for the formation of bolt through holes 51b, 53b, 55b through which terminal fixing bolts 80, 81, 82 screwed to terminals 40, 41, 42 pass through them; 54a, 55a, 56a are formed in the terminal locator grooves 51, 52, 53, 54, 55, 56, and for preventing short circuits between the drill center grooves 51a, 52a, 53a, 54a, 55a, 56a. The barrier ribs 91, 92, 93, 94, 95 and 96 are formed.
