Description

Electric connector

The utility model relates to a kind of electric connector, particularly relates to the electric connector that a kind of multi-layered high-density is arranged.

Electric connector terminal is the main element in the electric connector, it can be divided into butt end and substrate link substantially, wherein the butt end is arranged in the tank of insulation shell of electric connector, contact with the butt joint electric connector terminal realizing and conduct, its substrate link connecting circuit substrate realization conducts.The substrate link of terminal often was positioned on the center line of terminal overall profile and was symmetrical form in the past, as Taiwan patent application the 78212155th, 80101193,81205825,81212441,83210687,83212080 and No. 83212081 etc., and United States Patent (USP) the 4th, 175,821,4,720,276,4,720,277,4,721,484,5,151,056 and 5,252, No. 097 etc., but because computer is to gently, thin, short, little development trend, use the electric connector of multi-layered high-density terminal arrangement mode increasing, use the electric connector of aforementioned terminal terminal must be arranged with three-dimensional wrap direction again, or be staggered, just can realize double above high density of terminals arrangement with the terminal of more than one forms, as Taiwan patent application the 77207789th, 79214090,80209366,80207178,81212697,82213344,83216753,8420969,84208329 and No. 8411184 etc., but this way not only causes the electric connector volume to increase, and different terminal also needs to have increased manufacturing process and manufacturing cost with different die stampings.

For addressing the above problem, the utility model provides a kind of electric connector, and it can connect for butt connector, comprising: insulation shell, and it has the above terminal tank of three rows, and the described terminal tank of wherein at least one row is upset configuration up and down; Many rows carry son, are accommodated in the described terminal tank, and to realize electrical connection, wherein each terminal is provided with: the fixing fixed part of described terminal in the electric connector terminal tank; With the contact site that docks termination contact; Realize the substrate connecting portion that is electrically connected of described terminal and substrate, it is stretched by described fixed part one epitaxial lateral overgrowth, and the center line of the described fixed part of position deviation that is connected with described fixed part.

The advantage of the utility model device is, it can realize the arrangement of multi-layered high-density terminal with the terminal of single structure, makes simple and easyly, easy to assembly, dwindles taking volume, reduces cost.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
