The utility model content
The purpose of this utility model provides a kind of battery case connector pole system for detecting temperature, has ignored the problem that connector pole temperature detection causes in the prior art in order to solve.
For achieving the above object, scheme of the present utility model is: a kind of battery case connector pole system for detecting temperature, comprise for the positive and negative terminals of battery case connector fixing a pair of heat conduction sensing head respectively, be provided with thermistor in the heat conduction sensing head, thermistor is connected to temperature collecting device; Described heat conduction sensing head is made of Heat Conduction Material, the heat conduction sensing head be provided with for the suitable mounting hole of the double-screw bolt of battery case connector pole.
Described Heat Conduction Material is heat-conducting glue, and described thermistor integral packaging is in heat-conducting glue.Described thermistor is the thermistor of 10k Europe negative temperature coefficient.Described thermistor profile is drops.
Detection for battery case connector pole temperature, the utility model is measured the pole temperature by a heat conduction sensing head, temperature information is converted to the resistance information of thermistor, feed back to temperature collecting device, temperature collecting device carries out temperature monitoring and analysis, the early stage of loose contact occur at connector and just can monitor, and can access processing, thereby the continuation that effectively prevents loose contact worsens.The utility model adopts fixes the bolt of heat conduction sensing head and pole, can comparatively fast detect the temperature of battery case connector pole, and can guarantee the precision that detects.
Description of drawings
Fig. 1 is heat conduction sensing head schematic diagram of the present utility model;
Fig. 2 is connector pole temperature detection schematic diagram.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
A kind of battery case connector pole system for detecting temperature, comprise for the positive and negative terminals of battery case connector fixing a pair of heat conduction sensing head 1 respectively, such as Fig. 1, be provided with thermistor 2 in the heat conduction sensing head 1, thermistor 2 is connected to the breakout box of temperature collecting device by wire 4; Heat conduction sensing head 1 is by heat-conducting glue and thermistor 2 integral packaging secondaries.The line ball end of heat conduction sensing head 1 be provided with for the suitable mounting hole 3 of the double-screw bolt of battery case connector pole, during installation, mounting hole passes double-screw bolt, fixes with bolt again, just can fix with pole.
Such as Fig. 2, the signal of thermistor 2 is connected to the LECU of temperature collecting device by behind the breakout box of temperature collecting device, along with the variation of pole temperature, and the thermistor change in resistance, LECU informs control system with temperature.Thermistor 2 is the thermistor of 10k Europe negative temperature coefficient, and the thermistor profile is drops (ellipsoid shape).Above-mentioned sensing head can effectively reduce thermal resistance, comparatively fast detects the temperature of battery case connector pole, and can guarantee the precision that detects.
