In general, the jack box is one form of a bus tapping unit, and buses are generally copper buses and aluminum alloy buses respectively; the copper bus is made of pure copper, the aluminum alloy bus is made of aluminum alloy, and the copper bus is high in mechanical strength, corrosion-resistant and high in price; the aluminum alloy bus is lighter and has lower cost. The aluminum alloy bus has the problems of weak mechanical strength, easy corrosion and oxidation, the plugging mode of the plug box in the aluminum alloy bus needs special attention, and the plug box of the existing aluminum alloy bus has two plugging modes:

The first type is air type plug-in connection, and the plug-in ports of the intensive buses are connected according to an air type mode as the name implies; the problems are that: the air type heat dissipation is poor, so that the whole current-carrying capacity of the bus is restricted;

the second type is that 400A (A is current unit: ampere) current-carrying capacity and the load below are of dense plug-in type, and the 400A current-carrying capacity is of fixed connection type, and the problems of the fixed connection type are that: the bus section is nonstandard, the standard section production cannot be realized, and the cost is increased; the fixed plug box can not realize plug-and-pull, and the advantages of the plug box are lost;

Therefore, when the aluminum alloy bus runs at a high current (for example, more than 400A), convenient plugging cannot be realized, and meanwhile, the manufacturing cost is increased and the change caused by variation occurs in the drawing planning process. For example, when a test of charging a power battery of a new energy automobile is performed, a charging pile distributes power from three-phase alternating current (380 V+/-57V) through a bus jack box in a quick charging mode and rectifies the alternating current into direct current, and the current in the quick charging mode is larger, generally between 150 and 400A and even more than 400A; at this time, because of the high current characteristic and the need of frequent plugging in the test process of the charging of the power battery, the bus jack box has higher requirements on the whole current-carrying capacity and the plugging convenience.

In order to solve the technical problems, the embodiment of the application provides a bus jack box and a bus jack system, which are used for improving the access mode of the jack box from a connector, improving the competitive advantage of an aluminum alloy bus and a traditional copper bus from a new position and a new angle, and realizing the improvement of the plug convenience of the jack box; referring to fig. 1 to fig. 4, fig. 1 is a schematic structural diagram of a bus jack provided in an embodiment of the present application, fig. 2 is a schematic structural diagram of a jack housing provided in an embodiment of the present application, fig. 3 is a schematic structural diagram of a jack housing and a jack pin row provided in an embodiment of the present application, and fig. 4 is a schematic structural diagram of a jack pin row provided in an embodiment of the present application;
