At present, along with the economic development of society and the gradual improvement of the awareness of human environmental protection and energy conservation, new energy automobiles are also becoming more and more accepted. With the development of new energy automobiles, the requirements of people on the endurance mileage of the new energy automobiles are also increasing. In order to improve the endurance mileage of the new energy automobile, a technician proposes two solutions of quick charge and quick change. The quick-charging scheme reduces the charging time by increasing the charging rate, and the quick-changing scheme realizes the electric energy supplement by changing the battery with low electric quantity to a full-charged battery. In order to realize the quick-change scheme of the vehicle, the battery must meet the quick-change requirement, and the common connector needs to be replaced by a quick-change connector on the basis of the traditional battery so as to realize quick-change of the battery.

The inventor finds that the battery of the new energy automobile is generally installed on the chassis of the vehicle, the connector plug of the battery is in plug-in fit with the connector socket of the vehicle to realize the electric connection between the battery and the power utilization system of the vehicle, however, the connector plug of the battery is arranged at the top of the battery and is plugged upwards in the connector socket of the vehicle along the vertical direction, so that the phenomenon of water inflow is extremely easy to occur in the process of changing electricity after rainy weather or the vehicle wades. However, the connector plug in the prior art is provided with a sealing structure or a protective shell, so that two male end connecting terminals of the connector plug are arranged in the sealing structure or the protective shell to form a sealing interface, thereby playing a certain role in protection and sealing, however, due to the sealing structure or the protective shell also forming a closed space, the connector plug is easy to accumulate water after the water inlet phenomenon occurs in the sealing structure or the protective shell, and the accumulated water is not easy to discharge, thereby reducing the electric gap and the creepage distance between the two metal connecting terminals, easily causing the risks of abnormal electric connection and abnormal insulation, and further causing the short circuit phenomenon of the connector plug, so that the vehicle has a large potential safety hazard in the use process.

Based on the above consideration, in order to solve the problem that the vehicle has a large potential safety hazard in the use process, the inventor has conducted intensive studies and designed a connector plug, by canceling the protective housing on the connector plug and arranging a plurality of bosses on the base of the connector plug, each male end connecting terminal is respectively mounted on the corresponding boss, and a sealing element is arranged on each boss, so that the sealing element can seal the gap between the boss and the female end connecting terminal when the male end connecting terminal of the connector plug is plugged into the female end connecting terminal of the connector socket, thereby playing a sealing role.

In the quick-change process of the battery is realized by the connector plug with the structure, as each male end connecting terminal is arranged on the boss corresponding to the base, and each boss is provided with a sealing piece to seal a gap between the boss and the female end connecting terminal, on one hand, a protective shell is not required to be arranged, so that the risk of ponding is reduced when the connector plug is in a water inlet phenomenon, and ponding can be conveniently discharged after the connector plug is in water inlet, and thus the risks of abnormal electrical connection and abnormal insulation of the connector plug can be reduced, the potential safety hazard of a vehicle in the use process can be reduced, and on the other hand, each male end connecting terminal is independently sealed, so that the sealing interface only contains the single male end connecting terminal, and the risk of abnormal connection among a plurality of male end connecting terminals is reduced.

In addition, through setting up every public end connecting terminal on a boss, that is to say, every public end connecting terminal's bottom all is provided with the boss to can effectively increase the creepage distance between a plurality of public end connecting terminals, be favorable to reducing the risk of using of connector plug.

The connector plug disclosed by the embodiment of the application can be used for electric devices such as vehicles, ships or aircrafts, but is not limited to the electric devices. The power supply system with the connector plug, the battery and the like can be used for forming the power utilization device, so that the risk of abnormal electrical connection and abnormal insulation of the power utilization device is reduced, and potential safety hazards of the power utilization device in the use process are reduced.
