Aluminum hull is amplexiformed, structure is more simple and crude, is easy to scratch the aluminum hull of power battery, and due to directly contacting, thermal resistance has by aluminum hull
On the risk of electrolytic corrosion that is stained with.
Utility model content
The invention is to improve shortcoming in the prior art, and provide a kind of shell that will not scratch power battery
And the needle bed temperature probe for avoiding thermal resistance from being corroded.
For this purpose, providing a kind of needle bed temperature probe, including probe casing, the bottom of probe casing is equipped with the gold of arc-shaped
Belong to seal cap, metal sealing cap is built-in to be had for the thermal resistance to needle bed transmitting electric signal, between metal sealing cap and thermal resistance
Filled with thermal conducting agent, the signal pins of thermal resistance pass through probe casing and the one end not sealed from probe casing is stretched out.
Wherein, the thermal conducting agent is specifically silica gel.
Wherein, metal sealing cap and probe casing are integrally formed.
Wherein, the peripheral side of probe casing is equipped with the sleeve that can be fixed on needle bed.
Wherein, sleeve is slideably covered also is cased with spring, bullet on the peripheral side of probe casing, the peripheral side of probe casing
Spring is sandwiched between sleeve and metal sealing cap.
Wherein, the periphery of metal sealing cap is greater than the periphery of probe casing, to form ladder, one end of spring resists set
Cylinder bottom, the other end resist the ladder.
Wherein, location hole is provided on sleeve to be fixed on needle bed.
The utility model has the advantages that
The needle bed temperature probe of the utility model includes probe casing, and the metal that the bottom of probe casing is equipped with arc-shaped is close
Sealing cap, thermal resistance is interior to ensconce in metal sealing cap, avoids thermal resistance from directly contacting electrolyte and corroded, pushes in test step
Needle bed temperature probe makes the shell of metal sealing cap contact power battery realize heat transfer, by metal sealing cap and thermoelectricity
Thermal conducting agent is filled between resistance, the temperature on metal sealing cap is passed into thermal resistance, make thermal resistance is heated to generate electric signal, electricity
Signal is transferred to needle bed electric-control system through the signal pins across probe casing, since metal sealing cap is arranged to arc-shaped, under
Metal sealing cap will not scratch the shell of power battery during pressure, guarantee power battery product appearance.
Detailed description of the invention
The invention is described further using attached drawing, but the embodiment in attached drawing is not constituted to the invention
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is the structural schematic diagram of needle bed temperature probe.
Fig. 2 is the sectional view of needle bed temperature probe.
Specific embodiment
The invention is further described with the following Examples.
As shown in Figure 1, needle bed temperature probe includes a probe casing 1, the bottom of probe casing 1 is equipped with metal sealing cap
2 are sealed.Metal sealing cap 2 is made into semicircle shape, and bottom surface has circular arc, circular arc and power battery during pushing
Shell contact, avoid the shell for scratching power battery, guarantee power battery product appearance.See that Fig. 2, metal sealing cap 2 are built-in
Have for the PT100 thermal resistance 3 to needle bed transmitting electric signal, the signal pins 31 of PT100 thermal resistance 3 up pass through probe casing
1 and from the upper end that probe casing 1 is not sealed stretch out.Due to ensconcing in metal sealing cap 2 in thermal resistance 3, thermal resistance 3 will not be because
It directly contacts electrolyte and is corroded.Heat conductive silica gel A is poured into probe casing 1 from the upper end of probe casing 1, makes metal sealing
Full heat conductive silica gel A is filled in cap 2 and probe casing 1, thus fixed PT100 thermal resistance 3 and its signal pins 31.Test work
Needle bed temperature probe is pushed in sequence, the shell for making metal sealing cap 2 contact power battery realizes that heat transfer, heat conductive silica gel A again will
Temperature on metal sealing cap 2 passes to thermal resistance 3, makes thermal resistance 3 is heated to generate electric signal, electric signal is passed through across probe casing
1 signal pins 31 are transferred to needle bed electric-control system, for needle bed electric-control system acquisition and recording.It should be noted why adopting
It is thermally conductive with silica gel A, it is because the thermal coefficient of silica gel A is higher, is 0.63KJ/m. hr. DEG C, and it has dry, moisture-proof spy
Property, being applicable in very much the exposed environment of power battery electrolyte during needle bed charge-discharge test, (environment is specifically charge and discharge
Test process is needed to power battery progress dirt, should need to beat the cavity for being used to store electrolyte of power battery in the process
It opens, keeps electrolyte exposed, change electrolyte gas caused by dirt and externally shed).
To simplify needle bed temperature probe structure and its assembling process, in the fabrication process by metal sealing cap 2 and probe set
Pipe 1 is cast on together to be integrally formed.Certainly, another alternative uses 1 screw thread of metal sealing cap 2 and probe casing
The mode of connection is detachable to realize metal sealing cap 2.
Further, it is slideably cased with a sleeve 4 on the peripheral side of probe casing 1, is provided on sleeve 4 for fixing
Location hole 41 on needle bed, in use, sleeve 4 is fixed on needle bed by location hole 41.The peripheral side of probe casing 1 also covers
There is spring 5, spring 5 is sandwiched between sleeve 4 and metal sealing cap 2.Needle bed temperature probe, metal sealing are pushed in test step
Continue to push after cap 2 initial contact to the shell of power battery, stretches out probe casing 1 more above sleeve 4,5 quilt of spring
Compression generates elastic recovering force, and the elastic recovering force of spring 5 forces metal sealing cap 2 to be pressed on the outer of power battery under this state
On shell, guarantee heat conduction efficiency.To simplify 1 structure of probe casing, the periphery of setting metal sealing cap 2 is greater than probe casing 1
Periphery, so that the intersection of metal sealing cap 2 and probe casing 1 forms ladder, 5 one end of spring resists 4 bottom of sleeve, the other end
Ladder is resisted, and does not have to separately set fixing piece to resist for spring 5.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the invention, rather than to this hair
It is bright create protection scope limitation, although being explained in detail referring to preferred embodiment to the invention, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the invention, without departing from this
The spirit and scope of innovation and creation technical solution.
