The case can prevent liquid or other foreign matters from affecting the charge or discharge of the battery cells to some extent. In some cases, the battery cells may be used directly, i.e., the battery may not include a case, which is not limited herein.

In the battery, when the number of the battery cells is multiple, the battery cells can be connected in series or in parallel, and the series-parallel connection refers to that the battery cells are connected in series or in parallel. The plurality of battery monomers can be directly connected in series or in parallel or in series-parallel, and then the whole formed by the plurality of battery monomers is accommodated in the box body; of course, the battery can also be in a form of a battery module formed by connecting a plurality of battery monomers in series or parallel or series-parallel connection, and then connecting a plurality of battery modules in series or parallel or series-parallel connection to form a whole body and accommodating the whole body in the box body. The battery may further include other structures, for example, a bus member for making electrical connection between the plurality of battery cells.

The battery is used as a carrier and a supply source of electric energy, and needs to be charged and discharged for use. This requires the use of an electrical connector to connect the battery to an external circuit to effect charging and discharging of the battery. In the high-power charge and discharge application, the charge and discharge voltage and current are high, and correspondingly, the passing current in the electric connector is also high. Since the conductive contacts of the plug of the electrical connector are in contact with the conductive terminals of the receptacle for conducting electricity. And the contact position of the conductive contact and the conductive terminal has contact resistance, when large current passes through, larger heat can be generated, and the heat is focused in the electric connector, so that the normal use of the electric connector can be influenced, and even safety accidents can be caused.

In the prior art, a metal plate is arranged in the electric connector for heat dissipation, however, an insulating part is generally required to be used for supporting the conductive contact, so that the contact part of the conductive contact and the conductive terminal is difficult to conduct to the metal plate, and the heat dissipation performance is poor.

Water cooling is arranged in other electric connectors, and a liquid cooling pipeline is arranged inside the lead so as to realize liquid cooling and heat dissipation. However, the structure is large in size, the connector is inconvenient to use, and the damage to the pipeline inside the lead is easily caused by long-term vibration, so that the risk of short circuit occurs.

Based on the above consideration, in order to solve the heat dissipation problem of the electrical connector, the embodiment of the application provides an electrical connector, wherein the first heat conduction structure is made of a material comprising a phase change heat conduction material on the main body of the plug to support the conductive contact, so that the heat of the conductive contact and the conductive terminal can be actively absorbed, the conductive contact and the conductive terminal can be well dissipated, and the heat is conducted to the heat conduction base through the second heat conduction structure, so that the heat dissipation of the whole electrical connector is realized, the influence on the charge and discharge performance is reduced, and the charge and discharge safety is improved.

The electric connector disclosed by the embodiment of the application can be used for an electric device using a battery as a power supply or various energy storage devices using the battery as an energy storage element, such as an energy storage power supply system or an energy storage device applied to hydraulic power, firepower, wind power, solar power stations, energy storage cabinets and the like. The power device may be, but is not limited to, a cell phone, a tablet, a notebook computer, an electric toy, an electric tool, an electric bicycle, an electric motorcycle, an electric automobile, a ship, a spacecraft, and the like. Among them, the electric toy may include fixed or mobile electric toys, such as game machines, electric car toys, electric ship toys, electric plane toys, and the like, and the spacecraft may include planes, rockets, space planes, and spacecraft, and the like.
