As improvement, be respectively equipped with in the upper and lower both sides of said screen iron cover and prevent that screen iron cover from adorning the first anti-fool proof portion the utility model.

As improvement, be respectively equipped with the second fool proof portion that prevents that assembly is anti-inserted in the and arranged on left and right sides of said screen iron cover to the utility model.

As the improvement to the utility model, the material thickness of the front end of said plural upper terminal and plural lower terminal is less than the material thickness of the middle rear end of said plural upper terminal and plural lower terminal.

The utility model also provides a kind of connector that includes above-mentioned arbitrary said PDMI line-end connector assembly; Connector comprises upper casing and lower casing; Said upper casing and lower casing become complete box body after fastening, and the welding position of said PDMI line-end connector assembly is in said box body.

As improvement, in said box body, also be provided with the wire clamp that is used to locate external connection to the utility model.

The utility model is owing to adopted split type grab and U-shaped grounding elastic part structure, the relatively good Miniaturized problem of connector that solved; The structure that connector adopts arch shrapnel and plural terminals to adopt head to thin has overcome the not enough problem of connection space; Connector adopts and shell integral type button, practices thrift a mold, reduces artificial built-up time, and can reach the purpose of accurate positioning.
