Abstract
The utility model provides an easy-installing temperature sensor of a wire connecting terminal, belonging to the technical field of testing. The easy-installing temperature sensor is used for solving the installing problem. The technical scheme of the easy-installing temperature sensor is as follows: the easy-installing temperature sensor comprises the sensor used for measuring the temperature; a fixed clamping seat is additionally arranged at the outer part of the sensor, a U-shaped groove which is matched with an insulating jacket of a cable connected with the wire connecting terminal is arranged at one face of the fixed clamping seat, a groove which is matched with the temperature sensor is arranged at the inner part of the U-shaped groove, and the sensor is fixed in the groove. The easy-installing temperature sensor can be conveniently and reliably fixed at the root part of the cable which is connected with the wire connecting terminal under the circumstance of not affecting the connecting reliability of the present cable; moreover, the easy-installing temperature sensor has the characteristics of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of temperature sensor that is used for monitoring panel box, switch board cable connecting terminal heating situation, belongs to technical field of measurement and test.
Background technology
In train panel box, switch board, used a large amount of connection terminals, if connection terminal is connected reliably with cable, and the terminal screw is fastening normal, then under big current work situation, the temperature rise of terminal is normal substantially, can not produce abnormal failure.When train is advanced, because jolting of rail, various electric components meeting high vibrations in panel box, the switch board, it is loosening that connection terminal is connected, contact resistance increases, and causes terminal unusual temperature rise to occur when big current work, if untimely processing, but therefore fire hazard is necessary the terminal temperature is monitored.
Traditional temperature monitoring method can be divided into wireless monitor and by two kinds of temperature sensor monitors, the wireless monitoring device cost is too high, is difficult to allow the people accept.If adopting temperature sensor monitors the terminal temperature, then need temperature sensor is fixed near connection terminal head or its, but because most of cables and consumer joint do not allow to change, to prevent to influence the connection reliability of existing cable, cause equipment failure, thereby the difficulty of sensor installation becomes very big.Therefore, how that the temperature sensor of monitoring equipment is fixing reliably, do not influence the reliability that existing cable connects again, be the difficult problem that the technician faces.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of need not change the easy-to-install connection terminal temperature sensor that just can easily and reliably be fixed to existing connection terminal.
The alleged problem of the utility model is that the following stated technical scheme realizes:
A kind of easy-to-install connection terminal temperature sensor, it comprises a sensor that is used to measure temperature, Fixing clamp-seat is set up in outside at described sensor, the one side of described Fixing clamp-seat is provided with the U-lag that the insulating sheath with cable that connection terminal connects is complementary, also be provided with the groove that is complementary with temperature sensor in U-lag inside, described sensor is fixed in the groove.
Above-mentioned easy-to-install connection terminal temperature sensor is provided with tie-hole in the outside of U-lag.
When installing, the utility model need not dismantle original connection terminal, only need make U-lag and connection terminal connect that the cable root fits together and with band Fixing clamp-seat and cable are tied firm getting final product, U-lag can make the installation of Fixing clamp-seat more firm, groove in the U-lag then is used for temperature sensor is positioned, and makes it reliably to contact towards cable that connection terminal connects and with cable all the time; Purpose in the outer setting tie-hole of U-lag is to prevent that band from coming off from Fixing clamp-seat, improves this device reliability.The utility model can easily and reliably be fixed in connection terminal and connect the cable root under the situation that does not influence the existing cable connection reliability, and simple in structure, with low cost.
Description of drawings
Fig. 1 is the planform figure of Fixing clamp-seat in the utility model;
Fig. 2 is that sensor is installed in the position view in the Fixing clamp-seat;
Fig. 3 is that the utility model is installed in the position view on the cable.
Each label is among the figure: 1, groove; 2, sensor; 3, tie-hole; 4, band; 5, cable; 6, Fixing clamp-seat; 7, sensor pin, 8, U-lag.
Embodiment
Referring to Fig. 1, Fixing clamp-seat 6 top by with connection terminal the U-lag 8 that is complementary of the insulating sheath of company's cable, the groove 1 with temperature sensor 2 couplings is arranged at U-lag 8 middle parts, tie-hole 3 is arranged below Fixing clamp-seat 6.Fixing clamp-seat 6 forms for extraordinary nylon material compacting, the small and exquisite exquisiteness of outward appearance, intensity height, difficult aging, good insulation preformance.
Referring to Fig. 2, the groove 1 that sensor 2 is embedded in Fixing clamp-seat 6 is interior, coat Heat Conduction Material again, sensor 2 can reliably be contacted with cable surface be beneficial to heat conduction, sensor pin 7 is stretched out from a side of Fixing clamp-seat 6, the temperature-sensitive of sensor 2 is towards last, and should be a little more than the bottom of U-lag 2, to increase the pressure between temperature sensor 2 and the cable.
Referring to Fig. 3, U-lag 8 and cable 5 are fit together the back with band 4 binding Fixing clamp-seat 6 and cables 5, sensor 2 is closely contacted with the insulating sheath of cable 5, guarantee that heat-transfer effect is good.
After the utility model installed, sensor pin 7 was connected with testing circuit by connector, and testing circuit is suitably revised the signal of temperature sensor output, can calculate the temperature value of connection terminal.
Claims (2)
1, a kind of easy-to-install connection terminal temperature sensor, it comprises a sensor that is used to measure temperature, it is characterized in that, set up Fixing clamp-seat (6) in the outside of described sensor (2), the one side of described Fixing clamp-seat (6) is provided with the U-lag (8) that the insulating sheath with cable that connection terminal connects is complementary, also be provided with the groove (1) that is complementary with temperature sensor (2) in U-lag (8) inside, described sensor (2) is fixed in the groove (1).
