Abstract
The utility model discloses an electricity cabinet temperature alarm, including the warning light, the warning light includes the base, the one end of base is equipped with the casing, the other end of base is equipped with light permeable member, install the light source in light permeable member, and locate the binding post of casing bottom, be equipped with two -sided PCB printing plate in the casing, PCB printing plate simultaneously is equipped with the measuring circuit, the another side is equipped with warning circuit, the last thermistor that still is equipped with of PCB printing plate, thermistor's pin connects on PCB printing plate through the resistance eyelet welding, thermistor wears out the casing and has the clearance with the casing outer wall, binding post is connected with the measuring circuit electricity, light source and alarm circuit electrically connected. This electricity cabinet temperature alarm is small, and the energy consumption is low and measurement accuracy is high.
Description
Technical field：
This utility model is related to a kind of electricity cabinet temperature alarm.
Background technology：
In industrial and mining establishment, often result in in-cabinet temperature during unit exception in small space such as electronic box electricity cabinet too high, if not
Find in time, will result in failure propagation, the carrying out that impact produces.Existing electricity cabinet temperature alarm is typically case structure,
Not only volume is big, and high energy consumption is equipped with many requirements for installation position, and is connected by lead between sensor and wiring board,
Certainty of measurement is affected it is impossible to accurately reflect actual temperature.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of small volume, the electricity that energy consumption is low and certainty of measurement is high
Cabinet temperature alarm.
Technical solution of the present utility model is to provide a kind of electricity cabinet temperature alarm, including warning lamp, described warning
Lamp includes base, one end of base is provided with housing, the other end of base is provided with light transparent member, the light being installed in light transparent member
Source and the binding post located at housing bottom, are provided with two-sided PCB printed panel in housing, PCB printed panel one side is provided with measurement electricity
Road, another side is provided with warning circuit, and PCB printed panel is additionally provided with critesistor, and the pin of critesistor is connect by resistance eyelet welding
On PCB printed panel, critesistor passes housing and has gap with housing exterior walls, and described binding post and measuring circuit are electrically connected
Connect, described light source is electrically connected with warning circuit.
Using after above structure, compared with prior art, this utility model has advantages below：Existing warning lamp is entered
Row transformation, cancels the reduction voltage circuit in housing and lead originally, the substitute is the PCB printed panel of printed on both sides, PCB
The two sides of printed panel is respectively equipped with measuring circuit and warning circuit, and the pin of sensor critesistor is also welded in PCB print
On brush board, critesistor passes housing and is located at outside housing and keeps spacing with housing exterior walls, it is to avoid critesistor is subject to case temperature
Impact, adds that original binding post electrically connects with measuring circuit, described light source is electrically connected with warning circuit, makes entirely to warn
Lamp becomes an electric cabinet temperature alarm, not only small volume, installs and is not limited by space, and measuring circuit is divided with warning circuit
Not Bu Zhi assist side a face, both are each independent, will not interfere, in addition sensor also integrated in the circuit board,
Overcome the impact to certainty of measurement for the lead, improve certainty of measurement.
Preferably, the element of described measuring circuit and warning circuit is surface mount elements.Make product miniaturization, be easy to pacify
Dress size, identical with general warning lamp structure, it is easily installed.
Preferably, described housing is straight-tube shape structure, PCB printed panel is rectangle structure, and PCB printed panel is inserted in bottom
On seat.
Further, described housing is additionally provided with fixed installation hole.
Brief description：
Accompanying drawing is structural representation of the present utility model.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As illustrated, a kind of electricity cabinet temperature alarm, including warning lamp, described warning lamp include base 1, the one of base 1
End is provided with housing 2, the other end of base 2 is provided with light transparent member 3, the light source being installed in light transparent member and located at housing bottom
The binding post 6 in portion, is provided with two-sided PCB printed panel 4 in housing 2, PCB printed panel 4 one side is provided with measuring circuit, and another side is provided with
Warning circuit, the element of described measuring circuit and warning circuit is surface mount elements, makes product miniaturization, is easily installed, and PCB prints
Critesistor 5 is additionally provided with brush board 4, the pin of critesistor 5 is connected on PCB printed panel by resistance eyelet welding, and critesistor 5 is worn
Go out housing and with housing exterior walls, there is gap, described binding post 6 is electrically connected with measuring circuit, described light source is electric with warning circuit
Connect.Preferably, described housing 2 is straight-tube shape structure, PCB printed panel 4 is rectangle structure, and PCB printed panel 4 is inserted in bottom
On seat, further, for convenience of fixedly mounting, described housing 2 is additionally provided with fixed installation hole.Total of the present utility model
Utilize existing warning lamp structure to greatest extent, and improve and become temperature alarming device, make this utility model miniaturized structure, and
And certainty of measurement is high it is adaptable to all electricity cabinets are installed.
Below only this utility model preferred embodiment is described, but is not to be construed as the limit to claim
System.Every equivalent structure being done using this utility model description and accompanying drawing content or equivalent flow conversion, are included in this
Within the scope of patent protection of utility model.
