Description

The combined electric connector of grafting printed circuit board (PCB)

The utility model relates to a kind of combined electric connector of the printed circuit board (PCB) of pegging graft, but is meant the multiple different electric connector of a kind of combination in any especially, and combined electric connector simple in structure, that the assembly work station is few.

The product of computer and ancillary equipment thereof, also develops towards direction compact and that be easy to carry about with one except having functions such as voice, image, 3-D cartoon simultaneously through updating.According to this development trend, the connector that has turn-on power and signal serial connection function in the computer also needs enough matching design relatively, so that can be connected in series to motherboard smoothly with the equipment of the synchronous upgrading of computer.Electric connector in the existing printed circuit board (PCB) is arranged in an edge side of motherboard mostly, and after main frame was finished assembling, coverboard formed the grafting port in the wings, as the bridge of each ancillary equipment of conducting.Yet along with the amplification rapidly of ancillary equipment, the grafting port that existing arrangement mode is provided is applied and is used, and independent connector need be assembled on the motherboard one by one, has not only taken manpower but also time-consuming.So, utilize framework to pile up each connector, only need once be plugged to printed circuit board (PCB), both can save usage space and raised the efficiency.About the document of this part, can be with reference to No. the 80208088th, Taiwan patent application, the U.S. the 4818239th and No. 5080609 patent.In addition, utilize the design of framework in conjunction with dissimilar connectors, can be with reference to the U.S. the 5401192nd and No. 5407366 patent.

Although many Frame Design can obtain Expected Results, yet its problem of deriving also makes industrial circle feel to lose more than gain; This is because available frame comprises a plurality of members, and therefore increasing assembling procedure wastes man-hour; Simultaneously, available frame designs at traditional connector, and for cooperating the connector of difference in functionality, the size of framework and profile also have sizable difference, and therefore same framework is only applicable to certain style connector, lacks interchangeability.

The purpose of this utility model is to provide a kind of combined electric connector of the printed circuit board (PCB) of pegging graft, and its designs simplification can adapt to varying environment, save space shared on motherboard, and the assembly work station is few.

The purpose of this utility model is to realize like this, a kind of combined electric connector of the printed circuit board (PCB) of pegging graft promptly is provided, it comprises: at least one connection body, it has one first composition surface and one second composition surface, be respectively the apparent surface of described connection body, on described first composition surface flange is set, on described second composition surface groove is set; First electrical connector, the groove on its continuing surface are fixed on first composition surface of described connection body; Second electrical connector, the flange on its continuing surface are fixed on second composition surface of described connection body; At least one described combined electric connector is fixed in the fastening device of printed circuit board (PCB), it is engaged in described first or second electrical connector.

The advantage of the utility model device is that it can combine with various different connectors, and interchangeability is good, and configuration is simplified, and takies less space, and welding is easily fixing, uses manpower and material resources sparingly, and also can provide the product of a large amount of different shapes according to client's specific demand.
