Description of the embodiments

Embodiments of the present utility model are further described below with reference to the accompanying drawings.

As shown in fig. 1-4, a connector harness assembly comprises a housing 1, the housing 1 includes outer fringe 11 and a plurality of hole 12, the hole 12 can supply pencil 101 to pass through, the hole 12 is embedded to be equipped with shielding structure, shielding structure includes interior shielding hoop 5, outer shielding hoop 4, interior shielding hoop 5 cover is located pencil 101 surface, outer shielding hoop 4 locates between hole 12 wall and the interior shielding hoop 5 surface, the end of pencil 101 is equipped with binding post 2, housing 1 is equipped with tail cap 7 for binding post 2's outside, tail cap 7 and housing joint, set up buckle 33 on the tail cap 7, be equipped with the spacing portion 31 that is used for preventing buckle 33 excessively upwarp on the buckle 33, when need dismantle tail cap 7, relay when spacing portion 31 can be conveniently dismantled, prevent buckle 33 by excessively upwarp thereby take place the fracture, because tail cap 7 is integrated into one piece, buckle 33 fracture need wholly be changed, set up spacing portion 31 can effectively prevent its fracture, reduced maintenance cost.

In this embodiment, the limiting portion 31 is in an arch shape, and includes two connecting portions 32 and an arch portion 34, the two connecting portions 32 are respectively disposed on two sides of the buckle 33, and the arch portion 34 is disposed above the buckle 33.

Further, a sealing ring 6 is arranged between the tail cover 7 and the shielding structure, and the sealing ring 6 can ensure that the shielding structure positioned in the inner hole 12 is not influenced by the outside, so that the shielding effect is ensured.

Further, be equipped with a plurality of constant head tanks 35 on the tail-hood 7, correspond constant head tank 35 on the casing 1 and be equipped with a plurality of positioning lug 13, when tail-hood 7 and casing 1 joint, positioning lug 13 limit is located in the constant head tank 35, guarantee that tail-hood 7 and casing 1 are connected steadily firmly.
