The pure electric excavator works through the electric drive motor, and aiming at the excavator driven by the power battery, when the battery is low in electric quantity, the pure electric excavator needs to be charged, the charging has a direct current mode and an alternating current mode, when the alternating current is used for carrying out heavy current charging, a plurality of chargers need to work simultaneously, and then a single wire harness accessed from an alternating current power grid needs to be divided into a plurality of branch lines to be accessed to the chargers.

The technical scheme in the prior art is as follows:

at present, an alternating current charging wire bundle needs to be branched in a welding mode after being led out from an alternating current power grid, namely a plurality of wires needing to be branched are welded on one main wire bundle;

the alternating current charging wire uses a high-voltage shielding wire, and when welding, the shielding layers of the wires need to be peeled off and welded together, and meanwhile, the shielding layers of the wires need to be connected together and grounded;

the welding joint is subjected to thermal shrinkage and water proofing by using a thermal shrinkage pipe at present.

The prior art has the following disadvantages:

branching by adopting a welding mode, particularly the diameter of a high-current charging wire generally reaches 70mm, and the welding mode is unreliable;

the alternating current charging wire uses a high-voltage shielding wire, a shielding layer of a wire needs to be stripped and the shielding layers need to be welded together during welding, and the welding of the shielding layers is also unreliable;

the welding department uses the pyrocondensation pipe to carry out the pyrocondensation waterproof at present, probably the pyrocondensation is not in place when welding point pyrocondensation pipe pyrocondensation to welding both sides line footpath difference is great causes the welding point to have the gap, has the risk of intaking.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a branch box charges.

For solving the prior art problem, the utility model discloses a branch box charges, include: wire inlet gland head, case lid, the gland head of being qualified for the next round of competitions, box, insulated column and connection copper bar, wire inlet gland head is located one side of box, the gland head of being qualified for the next round of competitions is located the opposite side of box, the connection copper bar passes through the insulated column is located the inner chamber of box, it is equipped with inlet wire mounting hole and wire hole to connect the copper bar, the case lid is used for the lid to close the box.

Further, still include: the shell bonding column is arranged outside the box body.

Further, the method also comprises the following steps: and the exhaust hole is used for exhausting or air intake of the inner cavity of the box body.

Furthermore, the box cover is connected with the box body through a sealing rubber pad.

Furthermore, a waterproof rubber sleeve is arranged inside the inlet gland head and/or the outlet gland head.

Further, the insulating column is installed at the bottom of the inner cavity of the box body through rivets.

The utility model discloses beneficial effect who has:

the copper bar connection replaces a welding mode, the waterproof box body replaces a heat shrink tube to enable the high-voltage charging harness to be safer and more reliable, and the occurrence of electric leakage accidents in the using process is effectively avoided.
