Described lock screw stretches out location hole.
The external part of described lock screw is fixed by nut check, is provided with spring shim, flat shim between described nut and the location hole.
Described copper compression terminals afterbody is provided with the compression end of crimping attached cable copper conductor.
Described base is provided with 5 copper rods, and described T connector, copper compression terminals, lock screw are equipped with 5 groups.
Also comprise tarpaulin, this tarpaulin is plugged in the top of T connector.
Also comprise the insulation bolt, this insulation bolt is set on the untapped copper rod that is enclosed with electro-insulating rubber.
Also comprise lining, this lining is plugged in the cable inlet end of T connector.
Compared with prior art, advantage of the present invention comprises:
(1) in narrow ground, in the inlet port, can connect maximum 5 branches (main line 1, branch 4);
(2) in narrow ground in the inlet port, the cable of connection can be by overbending;
(3) hydraulic pressure of 0.5kg/cm2 does not have water yet and is immersed in the connector in the time of can bearing maximum water depth and be 5m.
