Background technology
Thermal resistance is a kind of temperature detection Automation Elements that middle low-temperature space is the most frequently used, is widely used in industrial temperature and surveys
Amount, currently mainly uses three-wire system PT100 formula thermal resistance.When three-wire system PT100 formula thermal resistance carries out temperature survey, from thermal resistance
Three lines of length and equal diameters are drawn at two ends altogether, and wherein a measurement signal line is drawn in one end, and the other end draws two surveys
Amount holding wire, the resistance of thermal resistance body deducts the resistance of both threads, the resistance of thermal resistance body equal to the resistance between two end lines
Value precise reaction temperature.
Thermal resistance check meter is mainly used in thermal resistance periodic inspection and measures the detection in loop.In thermal resistance inspection work,
When using the simulation of thermal resistance check meter to send three-wire system PT100 resistance signal, need to be from the jack of tester resistance signal two ends
Drawing length and three lines of equal diameters altogether, wherein single line is drawn in one end, and the other end draws two.Because work at present is adopted
With two single-line type wiring test pencils, generally need a test pencil end parallel connection from which to fix an extra supported signal line, then it is connect
Enter to measure loop, it has not been convenient to easily occur at staff's wiring and parallel connection to loosen.It addition, wiring test pencil predominantly pointer-type or
, also there is slip at terminal connections and get loose phenomenon in common alligator clamp.Because the measurement of resistance signal is affected greatly by wiring stability,
Slight loosening i.e. may result in resistance signal extremely, has a strong impact on certainty of measurement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of thermal resistance check meter fast-wiring
Test pencil, this thermal resistance check meter fast-wiring test pencil is reasonable in design, when using this test pencil to carry out thermal resistance regular maintenance and inspection,
More convenient can be efficiently completed verifying work task.
Realizing the technical scheme that this utility model purpose used is, a kind of thermal resistance check meter fast-wiring test pencil, bag
Include double lead fast-wiring test pencil and single lead-in wire fast-wiring test pencil, described double lead fast-wiring test pencil by binding post, two
Root wire and two wire clamps are constituted, and one end of two wires is all connected with binding post, the other end and is connected with two wire clamps respectively；Institute
State single lead-in wire fast-wiring test pencil to be made up of the binding post being linked in sequence, wire and wire clamp；Two folders up and down of described wire clamp
The inside of tooth is equipped with line ball steel plate.
Described binding post is sealed banana plug.
Described wire clamp is steel alligator clamp.
Described line ball steel plate is positioned at the folder point of wire clamp, and the position of two line ball steel plates is relative.
Before described line ball steel plate is positioned at the first sawtooth of wire clamp.
As shown from the above technical solution, the thermal resistance check meter fast-wiring test pencil that this utility model provides, for thermoelectricity
Special wiring demand during resistance inspection, designs double lead fast-wiring test pencil and the knot of single lead-in wire fast-wiring test pencil combination
Structure, wherein double lead fast-wiring test pencil is made up of binding post, two wires and two wire clamps, single lead-in wire fast-wiring test pencil
It is made up of the binding post being linked in sequence, wire and wire clamp, double lead fast-wiring test pencil and single lead-in wire fast-wiring test pencil
Three wire clamps are connected with three temperature terminal of three-wire system PT100 respectively, and binding post is sealed banana plug, convenient insertion
Tester test pencil wiring hole, one end of wire is connected with binding post, the other end is connected with wire clamp, it is achieved the transmission of the signal of telecommunication,
Wire clamp is steel alligator clamp, and the inside of two clip tooths up and down of wire clamp is equipped with line ball steel plate, clamps temperature terminal by wire clamp,
The sharp structure making Guan Bi of folder of wire clamp closed by line ball steel plate simultaneously, and wire clamp is connected jail with the wire of temperature survey terminal
Gu, be difficult to get loose.
The thermal resistance check meter fast-wiring test pencil that this utility model provides has the advantage that 1) stability, wire clamp connects
