Preferably, the control circuit board is composed of a control chip and a control circuit, the male end hot plug signal pin 140 is connected to the control chip through a line, because the female end hot plug signal pin 240 is connected to a positive electrode line of the control circuit of the load through a line, after the male end hot plug signal pin 140 is contacted with the female end hot plug signal pin 240, the control chip will obtain a connection signal, such as a high level signal or a current signal, at this time, the control chip will send an instruction to the control circuit to realize the conduction of the charging and discharging circuit of the battery pack, such as the conduction of the control switch element to realize the conduction of the charging and discharging circuit of the battery pack. On the contrary, after the male end hot plug signal pin 140 is disconnected from the female end hot plug signal pin 240, the control chip loses the connection signal and sends an instruction to the control circuit to cut off the charging and discharging circuit of the battery pack, so that the electric spark generated in the hot plug process of the high-power battery connector can be avoided, and the problem of the service life reduction of the connector caused by the hot plug is solved.

The utility model discloses control system is inserted to hot drawing's theory of operation as follows:

the structure of the high-power battery connector is improved, a male end positive and negative electrode connecting needle for realizing electric transmission and a male end hot plug signal needle 140 for realizing hot plug control are arranged in a male end boss 120 of a male end 1 of the connector, similarly, a female end positive and negative electrode connecting needle for realizing electric transmission corresponding to the male end positive and negative electrode connecting needle is arranged in a female end ring groove 220, and a male end hot plug signal needle 140 for realizing hot plug control corresponding to the male end hot plug signal needle 140 is arranged in the female end ring groove 220. In particular, in order to avoid the electric spark generated when the male end 1 and the female end 2 of the connector are electrically pulled out, the male and female end positive and negative connecting pins are disconnected, the utility model discloses design the male end hot-plug signal pin 140 and the female end hot-plug signal pin 240 as the first disconnection contact, and design the connection of the male end positive and negative connecting pins and the female end positive and negative connecting pins as the second disconnection contact, that is, when the male end 1 and the female end 2 of the connector are plugged into each other, design the connection of the male end positive and negative connecting pins and the female end positive and negative connecting pins as the first contact, and design the connection of the male end hot-plug signal pin 140 and the female end hot-plug signal pin 240 as the second contact. Therefore, will the utility model discloses public end 1 of connector sets up on the lithium cell as the battery end, will the utility model discloses female end 2 of connector sets up on the storage battery car as the locomotive end, insert the battery end when serving the locomotive, although the positive negative pole of battery end contacts earlier with the positive negative pole of locomotive end, but this moment, the control circuit board of battery end is non-electrified through control circuit control lithium cell, therefore, can not produce the electric spark, wait to the hot plug signal needle of hot plug signal needle and the locomotive end of battery end contact the back, feedback signal gives the control circuit board of battery end, control circuit board opens immediately or postpones the battery pack formal circular telegram that the battery end was opened again to the settlement time through control circuit, electric spark takes place when can avoiding the connector to peg graft.

Similarly, when the battery end is pulled out from the locomotive end, the hot plugging signal pin of the battery end and the hot plugging signal pin of the locomotive end are disconnected firstly, at the moment, the control circuit board of the battery end immediately disconnects the power supply of the battery end due to the loss of the feedback signal of the hot plugging signal pin, and electric sparks are not generated when the positive and negative electrodes of the battery end are disconnected with the positive and negative electrodes of the locomotive end after the battery end is in the power-off state. Therefore, the utility model discloses high-power battery connector and hot plug control system can support high-power battery unlimited hot plug (electrified or take the load operation), can insert for high-power load's hot plug provides the guarantee, also can not be because of the maloperation, lead to the connector life-span to descend.

The utility model discloses in the above-mentioned embodiment, given the public end 1 of connector and carried out the example of being connected with the battery end, in other embodiments, can replace public end 1 of connector and female end 2 of connector, it can to change public, female end hot plug signal needle 240's connected mode simultaneously.

The above embodiments have been described in detail with reference to the accompanying drawings. Those skilled in the art can make various modifications and changes to the above embodiments without departing from the spirit of the present invention, and the scope of the present invention is also covered by the appended claims.
