Utility model content
Technical problem to be solved in the utility model is: provide a kind of battery charging and discharging detector probe carrying out Real-Time Monitoring when charging and discharging lithium battery to battery temperature.
For solving the problem, the technical solution adopted in the utility model is: the battery charging and discharging detector probe of lithium battery, comprise shank, the inside of shank is provided with voltage probe, and the outer cover of shank is provided with orienting sleeve, and the shank above orienting sleeve has been threaded feeler lever guide nut, the bottom of shank is syringe needle is the protuberance that diameter is larger, shank between syringe needle and orienting sleeve is provided with spring, and the bottom of described probe is provided with temp probe, has temperature sensor in temp probe.
Preferably, be provided with center pit in described temp probe, the size of center pit matches with the lower diameter of shank, and center pit is set on shank, by the lower end of spring make temp probe and syringe needle inconsistent.
Further technical matters to be solved in the utility model is: provide one automatically to adjust, to make the battery charging and discharging detector probe of lithium battery that between battery charging and discharging detector probe and the two poles of the earth of lithium battery, forming surface contacts.
For solving the problem, the technical solution adopted in the utility model is: the upper diameter of described shank is greater than lower diameter, the shank being positioned at the below of feeler lever guide nut has been threaded spigot nut, the bottom of spigot nut is the conical surface, the top of described orienting sleeve is the hydraucone shape matched with the conical surface, the lower inner wall of orienting sleeve is provided with bulge loop, and the internal diameter of bulge loop and the upper diameter of shank match.
The beneficial effects of the utility model are: above-mentioned battery charging detector probe, it is by being connected with temp probe and temperature sensor in the bottom of shank, thus the real time temperature of syringe needle and battery can be detected when carrying out charge and discharge to lithium battery, when temperature is too high, charge and discharge process can be stopped in time, allow equipment report to the police simultaneously, remind operating personnel, to analyze heating cause.The reason of loose contact then readjusts the contact condition between battery charging detector probe and the two poles of the earth of lithium battery in this way, thus efficiently avoid probe contact with lithium battery pole major gene unreliable or contact resistance is excessive and produce superheating phenomenon, avoid probe and pole to burn because of overcurrent, improve the serviceable life of probe.In addition, the shank of this battery charging detector probe has self-adjusting structure, the inclination can carrying out certain angle according to the state at the two poles of the earth of lithium battery realizes coordinating, avoid the phenomenon forming point cantact between battery charging detector probe and the two poles of the earth of lithium battery to a certain extent to occur, further increase probe and pole contact reliability.Early warning is made in the blast that simultaneously also likely can produce because heating excess temperature in Timeliness coverage Production Process of Lithium Battery, improves the security that lithium battery is produced.

Embodiment
Be described in further detail below by the battery charging and discharging detector probe of specific embodiment to a kind of lithium battery described in the utility model.
As shown in Figure 1 and Figure 2, the battery charging and discharging detector probe of lithium battery, comprise shank 1, the inside of shank 1 is provided with voltage probe 2, and the outer cover of shank 1 is provided with orienting sleeve 3, and the shank 1 above orienting sleeve 3 has been threaded feeler lever guide nut 4, the bottom of shank 1 is syringe needle 5 is the protuberance that diameter is larger, shank 1 between syringe needle 5 and orienting sleeve 3 is provided with spring 6, and the bottom of described voltage probe 2 is provided with temp probe 7, has temperature sensor in temp probe 7.
Preferably, be provided with center pit 8 in described temp probe 7, the size of center pit 8 matches with the lower diameter of shank 1, and center pit 8 is set on shank 1, makes temp probe 7 and syringe needle 5 inconsistent by the lower end of spring 6.By spring 6, temp probe 7 is pressed on the syringe needle 5 of shank 1, and passes through the cooperation of center pit 8, the reliable connection of temp probe 7 can be ensured.
Preferably, the upper diameter of described shank 1 is greater than lower diameter, the shank 1 being positioned at the below of feeler lever guide nut 4 has been threaded spigot nut 9, the bottom of spigot nut 9 is the conical surface, the top of described orienting sleeve 3 is the hydraucone shape matched with the conical surface, the lower inner wall of orienting sleeve 3 is provided with bulge loop 10, and the internal diameter of bulge loop 10 and the upper diameter of shank 1 match.Coordinated and the effect of bottom bulge loop 10 by upper inclined surface, make the top being arranged on shank 1 that orienting sleeve 3 is stable, and ensure that shank 1 and orienting sleeve 3 keep when relative movement almost coaxial to move.
Principle of work of the present utility model is: first, two above-mentioned battery charging detector probe are used to contact with the two poles of the earth of lithium battery respectively, at probe a jointing 11 is set between cap 4 and spigot nut 9 for galvanization, thus lithium battery is charged, by being connected with temp probe 7 in the bottom of shank 1 and connecting temperature sensor, thus the real time temperature of shank 1 bottom can be detected when charging to lithium battery, when temperature is too high, charging can be stopped in time, and the contact condition readjusted between battery charging detector probe and the two poles of the earth of lithium battery, thus efficiently avoid battery charging detector probe and lithium battery there is superheating phenomenon, avoid battery charging detector probe and burn the generation with lithium battery blast, improve security.
In addition, when above-mentioned battery charging detector probe is charged, along with moving down of orienting sleeve 3 and shank 1, the bottom of voltage probe 2 and the two poles of the earth of lithium battery inconsistent, orienting sleeve 3 continues to be displaced downwardly to the thin diameter segment in bottom that orienting sleeve 3 is positioned at shank 1, the bottom of shank 1 and the two poles of the earth of lithium battery inconsistent, now there is larger gap between the inwall of orienting sleeve 3 and the bottom outer wall of shank 1, when being point cantact between the bottom and the two poles of the earth of lithium battery of shank 1 and voltage probe 2, shank 1 can carry out suitable inclination in orienting sleeve 3, forming surface between the bottom of shank 1 and voltage probe 2 and the two poles of the earth of lithium battery is contacted, further increase security.
After charging complete, voltage probe 2 rises overally, shank 1 under spring 6 acts on relatively orienting sleeve 3 move down, under the double action on the inclined-plane of bottom bulge loop 10 and top guide nut 9, shank 1 can automatically reset to vertical state.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
