Description
Technical field
The utility model belongs to technical field of temperature measurement, and in particular to a kind of thermometer spring compression joint type connecting terminal.
Background technique
The armoured thermometer that 1, No. 2 unit of certain nuclear power station uses more than 700 branch Rosemounts to produce, thermometer are directly installed on
On thermometer boss or hot trap, casing or hot trap are mounted in process pipe or equipment using welding manner.Since unit quotient transports
Use experience show that the type thermometer performance is relatively stable, but the thermometer wiring being frequently found in certain equipment loosen or
The case where wiring is broken.
Part processing equipment, pipeline body vibration frequency are higher, cause the wiring of thermometer original thread formula easily de- by vibration；If
Because high-frequency vibration is difficult to fasten wiring when overhauling thermometer between the received shipment departure date；Meanwhile screw-type wiring easily the fastening end period of the day from 11 p.m. to 1 a.m because
Overexertion causes the too deep and easy vibration of wiring impression disconnected.
Summary of the invention
The technical issues of the utility model solves:
The utility model provides a kind of thermometer spring compression joint type connecting terminal, increases the vibration resistance of connecting terminal, avoids
Wiring loosens；Meanwhile the binding post of original thread connection is eliminated because of the firmly excessive damage to core.
The technical solution adopted in the utility model:
A kind of thermometer spring compression joint type connecting terminal, including upper terminal, lower terminal, upper terminal threading hole, lower terminal are worn
String holes, upper terminal and spring weld, spring, lower terminal and spring weld；
Lower terminal is hollow cylindrical body, and lower end surface sealing, upper surface is provided with through-hole；Upper terminal is cylindrical body, is passed through down
The through-hole of terminal upper surface；The upper terminal of the lower end surface of upper terminal is connect with one end of spring weld and spring, spring it is another
One end is connect with the lower terminal on lower terminal interior lower end face with spring weld；Under upper terminal threading hole is located in upper terminal
Portion, lower terminal threading hole is two short cylinder holes, positioned at the middle and upper part of lower terminal.
When spring is in relaxed state, upper terminal threading hole is higher than lower terminal threading hole.
When wiring, upper terminal is moved down, compressed spring, when upper terminal threading hole and lower terminal threading hole grade height, electricity
Cable wiring is also cross upper terminal threading hole and lower terminal threading hole.
The utility model has the beneficial effects that
(1) a kind of thermometer spring compression joint type connecting terminal provided by the utility model, increases the vibration resistance of connecting terminal,
Wiring is avoided to loosen；Meanwhile the binding post of original thread connection is eliminated because of the firmly excessive damage to core；
(2) a kind of thermometer spring compression joint type connecting terminal provided by the utility model has line convenient and efficient, antivibration
The characteristics of performance is good, will not damage cable core, is worthy to be popularized onto the connecting terminal of other high-frequency apparatus.

Specific embodiment
In the following with reference to the drawings and specific embodiments to a kind of thermometer spring compression joint type terminals provided by the utility model
Son is described in further detail.
As shown in Figure 1, a kind of thermometer spring compression joint type connecting terminal provided by the utility model, including upper terminal 1, under
Terminal 2, upper terminal threading hole 3, lower terminal threading hole 4, upper terminal and spring weld 5, spring 6, lower terminal and spring weld
Place 7；
Lower terminal 2 is hollow cylindrical body, and lower end surface sealing, upper surface is provided with through-hole；Upper terminal 1 is cylindrical body, is passed through
The through-hole of 2 upper surface of lower terminal；The upper terminal and spring weld 5 of the lower end surface of upper terminal 1 and one end of spring 6 are welded and are connected
It connects, the other end of spring 6 and the lower terminal on 2 interior lower end face of lower terminal and spring weld 7 pass through welded connecting；Upper terminal
Threading hole 3 is located at the middle and lower part of upper terminal 1, and lower terminal threading hole 4 is two short cylinder holes, in lower terminal 2 on
Portion；When spring 6 is in relaxed state, upper terminal threading hole 3 is higher than lower terminal threading hole 4.
As shown in Fig. 2, upper terminal 1 moves down when wiring, compressed spring 6, when upper terminal threading hole 3 is worn with lower terminal
When string holes 4 etc. is high, cable connection 8 is also cross upper terminal threading hole 3 and lower terminal threading hole 4.
