Description

Socket connector

[technical field]

The utility model relates to a kind of socket connector, and is especially a kind of in order to electrically connect the planar lattice array socket connector of central processing unit.

[background technology]

Electric connector of planar grid array is because of saving space, the stable computer realm that is widely used in of electric property, to electrically connect central processing unit and printed circuit board (PCB), realizes the transmission of data and signal between the two.

Prior art has disclosed multiple electric connector of planar grid array, has all disclosed this kind electric connector of planar grid array No. 03271908.6 as No. the 03251162.0th, Chinese patent of announcing on July 28th, 2004 and the Chinese patent of announcing on October 27th, 2004.

Above-mentioned electric connector of planar grid array of the prior art generally comprises insulating body, be placed in plurality of conductive terminals in the insulating body, be located in insulating body 4 outsides the metal reinforced sheet, be articulated in metal reinforced sheet one end in order to compressing the pressing plate of central processing unit, and be articulated in the driving lever that the metal reinforced sheet other end can fasten with pressing plate.The part that pressing plate and metal reinforced sheet articulate is made as circular-arc usually, and in driving lever and pressing plate interaction process, driving lever can produce thrust to pressing plate forces pressing plate to moving away from the driving lever direction.The athletic meeting of pressing plate causes the central processing unit of pressing plate below to produce slippage because of frictional force, causes it to cooperate dislocation with connector terminal, even can make terminal bending fracture.

Be head it off, another prior art, is set up resistance portion at the circular-arc position of pressing plate and is solved this technical problem to shown in Figure 7 as Fig. 5, and details are as follows.

See also Fig. 5 and Fig. 6, existing planar lattice array socket connector 1 comprises insulating body 4, be placed in plurality of conductive terminals 5 in the insulating body 4, be located in insulating body 4 outsides metal reinforced sheet 6, be articulated in metal reinforced sheet 6 one ends in order to compressing the pressing plate 7 of central processing unit (not shown), and be articulated in the driving lever 8 that metal reinforced sheet 6 other ends can fasten with pressing plate 7.Insulating body 4 sidewalls 41 are provided with some positioning convex column 42, the following iron plate 68 corresponding grooves 62 of accommodating positioning convex column 42 that offer of metal reinforced sheet 6.When insulating body 4 was mounted on the metal reinforced sheet 6, positioning convex column 42 was placed in respectively in the corresponding grooves 62, and through hot melt or riveted joint and closely be immobilizated on the metal reinforced sheet 6.Pressing plate 7 is provided with circular-arc articulated section 71,71 phase epitaxies stretch out resistance portion 72 along the articulated section, the metal reinforced sheet is provided with the support sector 67 that the articulated section 71 with pressing plate 7 articulates, after pressing plate 7 is mounted to metal reinforced sheet 6, resistance portion 72 will be connected to support sector 67, thereby, when driving lever 8 interacts with pressing plate 7, even if 8 pairs of pressing plates of driving lever 7 produce thrust, also can offset this thrust because of resistance portion 72, prevent that whereby pressing plate 7 from moving away from the driving lever direction.

Yet this resistance portion 72 is located at the side of articulated section 71, can influence the pivot joint relation of pressing plate 7 and metal reinforced sheet 6, even can hinder the rotary course of pressing plate 7 around metal reinforced sheet 6.In addition, resistance portion 72 is arranged on by the side of circular-arc articulated section 71, and the bending operation is comparatively difficult after the punch forming, is unfavorable for the brake forming of articulated section 71.

In view of above-mentioned drawback, a kind of new-type socket connector of necessary design.

[utility model content]

The technical problems to be solved in the utility model provides and a kind ofly prevents the pressing plate slippage and articulate good socket connector with the metal reinforced sheet.

For solving the problems of the technologies described above, the utility model relates to a kind of socket connector, in order to electrically connect central processing unit, it comprises the insulating body that is installed on the printed circuit board (PCB), is contained in the plurality of conductive terminals in the insulating body, pressing plate and the driving lever that is located in the metal reinforced sheet in the insulating body outside and is articulated in metal reinforced sheet two opposite sides respectively.Pressing plate is provided with two opposed side edges, and dual-side tail end relatively bending is provided with two holding parts that are articulated in the metal reinforced sheet, and each holding part is provided with the thickness resistance side identical with the pressing plate sheet metal thickness.In pressing plate and driving lever interaction process, resist side and be connected to the side of metal reinforced sheet near driving lever.

With respect to prior art, the utility model socket connector has following advantage: resisting side is the part of pressing plate holding part, in the pressing plate punching course, can form, need not to establish in addition device, this resistance side can not influence the moulding of pressing plate holding part, and can effectively prevent pressing plate to away from driving lever direction motion, and then prevent that central processing unit from producing displacement.
