Description

Electric power connector

Technical field

This utility model relates to a kind of electric power connector, particularly to a kind of SAS (Serial being provided with shield shell Attached SCSI) electric power connector of transmission interface.

Background technology

The change that science and technology is maked rapid progress in recent years, high in the clouds technology quickly develops, thereupon along with significantly data quantity Transmission, now adapter transmission information has become indispensable key technology, from SCSI (Small Computer in early days System Interface) SAS (Serial Attached SCSI, tandem SCSI) till now, high speed information is accessed Demand tandem technology solve the bottleneck of Traditional parallel technology, it is provided that signal transfer functions and SAS can support faster And compatible with the equipment of SATA (Serial Advanced Technology Attachment), there is generally applicable advantage.

When adapter docks, between socket and plug, the most do not design preferably guide, so in docking Always can take a lot of time in para-position when para-position among process, the skew of a little angle of plug or dislocation, will make Plug docks with socket and has some setbacks, and even causes the damage of connector construction.

The inaccurate produced problem of para-position, No. 7226314 issued patents Shen of the U.S. during in order to overcome adapter to dock Case please disclose a socket connector A, as it is shown in figure 9, socket connector A has an insulating body B, a circuit board C and Guide housing D, insulating body B comprise a docking groove (figure does not indicates), and docking groove is opened in a surface of insulating body B, docking Groove is provided with multiple terminal groove (figure is undisclosed) relative to two surfaces, and multiple terminal (figure is undisclosed) is inserted in insulating body respectively In each terminal groove in the docking groove of B, each terminal respectively towards the opening of docking groove oppositely extending go out each welding foot (figure is public Open), each welding foot of insulating body B and terminal is separately fixed at circuit board C, and welding foot is electrically connected with circuit board.

Guide housing D is formed by sheet metal, and guide housing D comprises a upper plate D1, two dividing plate D2 and a pressure holding plate D3, Dual-side relative for upper plate D1 each extends over out each dividing plate D2 and forms a receiving space (figure does not indicates), and upper plate D1 is between dividing plate D2 Between a side extend the connection side of pressure holding plate D3, upper plate D1 and pressure holding plate D3 and extend two elastic arm D11, elastic arm D11 is positioned at pressure holding plate D3 opposite sides, and elastic arm D11 bends towards receiving space, and each elastic arm D11 is connected to upper plate D1 respectively The two kink D12 that front end is extended, each dividing plate D2 are in contrast to a side difference of the receiving space opening of pressure holding plate D3 side Being provided with a breach D21, each dividing plate D2 and extend multiple fixing foot (figure does not indicates), guide housing D is fixed on electricity by fixing foot Road plate C, and guide housing D is positioned at the docking groove open front of insulating body B, pressure holding plate D3 extends above insulating body B, makes Insulating body B, circuit board C and guide housing D are assembled into socket connector A.

In this patent application case, guide housing D is fixed on the docking groove open front of insulating body B, when described socket connects When connecing device A and a pin connector (figure is undisclosed) docking, pin connector is guided by elastic arm D11, can effectively provide The quick location of upright position, inserts in docking groove exactly by a hyoplastron of pin connector up and down, and by pin connector It is placed in the receiving space of guide housing D, cannot time of being wasted of para-position accurately when reducing adapter docking；And guide Housing D is that metal material is made, therefore guide housing D has good shield effectiveness, is coated with pin connector by guide housing D When high frequency signal transmission, there is the function of shielding external electromagnetic interference, and the noise that can be produced inside is by fixing foot Ground connection, can increase the yield of signal transmission.

But in this patent application case, when the hyoplastron of pin connector docks with socket connector A, though can accurately provide The para-position of vertical direction up and down, but not for the alignment issues proposition solution of horizontal direction, when adapter docks, Horizontal direction does not has accurate contraposition, causes hyoplastron easily left and right skew, because hyoplastron para-position is incorrect, easy scratch socket connector The insulating body B of A, causes the damage of insulating body B, and then affects the service life of socket connector A.

The ameliorative way that the insulation shell preventing socket connector cannot be provided to be scraped off due to the prior art meets product Industry actual demand, it is therefore desirable to provide the technical scheme of a kind of improvement to overcome predicament.
