Background

The temperature measuring device of a plurality of switch cabinet plum blossom contacts at present is directly attached to the outer wall of the switch cabinet plum blossom contact through plastic binding bands and the like, because errors exist in the butt joint process of the switch cabinet plum blossom contacts, the outer diameter of the switch cabinet plum blossom contacts can change, the switch cabinet plum blossom contacts are connected through the binding bands and the like and are not provided with elastic deformation capability or are poor in elastic deformation capability, the switch cabinet plum blossom contacts are inconvenient to install and detach, are very troublesome to use, are very difficult to replace, are very easy to age, are easy to damage, break or fail under the condition of expanding the outer diameter, are unstable in work, lead to stopping or inaccuracy of temperature measuring work, and lead to electric accidents due to the breakage of the binding bands.

Disclosure of Invention

The utility model aims to provide a temperature measuring device for the plum blossom contact of a switch cabinet, which is convenient to use and stable in structure, and is particularly suitable for temperature measuring work of the plum blossom contact of the switch cabinet.

The technical scheme of the utility model is as follows: the utility model provides a cubical switchboard plum blossom contact temperature measuring device, includes mounting panel, spring, temperature sensor and protective housing, the both ends of mounting panel set up the mounting hole, the central symmetry of mounting panel lateral wall sets up down the fixed orifices, mounting panel one side center sets up temperature sensor, temperature sensor bonds the mounting panel, the opposite one side center with temperature sensor on the mounting panel sets up the buckle, the buckle sets up two with mounting panel central symmetry about mounting panel, temperature sensor's outside sets up the protective housing, protective housing bilateral symmetry sets up the fixed orifices, it is coaxial with lower fixed orifices to go up the fixed orifices, it is the same with lower fixed orifices aperture size down to go up the fixed orifices, the spring both ends are connected respectively through the couple to the mounting hole at mounting panel both ends, spring welding couple, go up the fixed orifices and pass through the screw connection with lower fixed orifices.

Furthermore, the temperature sensor adopts RFID technology.

Further, the distance between the buckles is larger than the contact piece width of the plum blossom contact.

Further, the spring is an arc spring.

Further, the mounting plate and the buckle are made of metal and preferably copper.

The utility model has the advantages and positive effects that:

1. because the mounting plate is matched with the spring, the spring is wound outside the plum blossom contact of the switch cabinet, the mounting is simpler, the influence on the work of the plum blossom contact of the switch cabinet is reduced, and meanwhile, the spring can provide elastic deformation capacity when the plum blossom contact of the switch cabinet changes, so that the spring is tightly attached to the plum blossom contact of the switch cabinet, and meanwhile, the spring is connected with the mounting plate through the hook, so that the plum blossom contact of the switch cabinet is convenient to fix and detach, and the maintenance work is convenient.

2. Because the mounting panel has adopted the buckle, the buckle sets up in the side that is close to the plum blossom contact in pairs, fixes the mounting panel in the contact outside of plum blossom contact through the buckle, avoids the mounting panel to take place side-to-side or direction change, provides the locate function of installation, guarantees the stability of operating condition and the fixed of relative position, and the buckle card is established on the contact of plum blossom contact simultaneously, can also provide good laminating nature and temperature conduction's function, increases temperature detection's timeliness and precision.

3. Due to the adoption of the RFID temperature measurement technology, the temperature sensor can supply power wirelessly, temperature information is fed back in real time, temperature measurement is more timely, and the mounting plate and the buckle can conduct heat in time, so that timely and accurate measurement is ensured.

4. The protection shell is sleeved outside the temperature sensor, so that the safety of the temperature sensor can be protected, and the chip damage caused by collision in the working process is avoided.
