Description

Electric connector and terminal group thereof

Technical field

The utility model relates to a kind of electric connector and terminal group thereof, belongs to the technical field of electronic information technology product structure, belongs to the technical field of the interface product structure that is mainly used in electric connection in the electronic information technology product specifically.

Background technology

Now computer and electronics technology constantly bring forth new ideas, progressive epoch, make electronic product miscellaneous popularize in society, and along with science and technology is fast-developing, no matter be that computer, electronic product direction all strong towards calculation function, that speed is fast and volume is little strides forward, and just more and more trend towards microminiaturization because of the design of computer at present, make its inside also be tending towards narrow, dwindle thereby cause electronic building brick on the motherboard and electric connector all need cooperate thereupon for the space of putting electronic installation (as Winchester disk drive, CD-ROM drive etc.).

Only electric connector on the market is for including insulating base frame, complex conduction terminal and cable, and at cable with on conducting terminal combines, system directly adopts the soldering mode to connect, but because of the soldering operation comparatively loaded down with trivial details, inconvenient, also more not environmental protection, then less on the other hand because of the adjacent conductive terminal pitch, especially easily cause empty weldering together the time, connect weldering when many cables, even can't effectively weld also unfavorable production and processing.

And in order to solve the above problems, just having the dealer to adopt interconnects terminal group respectively earlier with the mode that each cable utilization grips or punctures, the terminal group that butts up against insulating base frame inside is again carried out combination, constitute wire pair board connector with group, can make things convenient for the contraposition assembling by this, simplify the program of processing, see also Fig. 7, shown in Figure 8, system is respectively the stereo appearance figure commonly used and Fig. 7 sectional drawing along the I-I hatching, wherein, this female terminal A is by being made up of beam arm A1 that enlarges simple-beam type attitudes partly in the middle of two and the root A2 that is positioned at beam arm A1 two ends, on using, reality still has many disappearances on this kind structure, its beam arm A1 only provides on the male terminal B, following two contact points, belong to unstable equilibrium, and make male terminal B easily towards a left side, the right side is offset and causes electric connection uncertain, and because of simply supported beam intermediate contact width partly is big than two ends, so stress will concentrate on root A2 turning point, cause the stress distribution inequality, then also might the generation type under permanent plug is used become or situation such as fracture.

Summary of the invention

The utility model is because above-mentioned problem of commonly using and disappearance, a kind of electric connector and terminal group thereof are provided, to realize to prevent that conducting terminal from producing excessive skew, and reduce that butt joint terminal generation stress is concentrated and distortion, type are cashed and resembled, all have better reliability degree no matter make on its electric connection or the overall construction intensity, and then make the more stable and certain purpose of signal transmission quality.

The technical solution of the utility model is in order to achieve the above object:
