Description
[technical field]
The relevant a kind of electric connector of the present invention, especially a kind of zero-force connector for socket that is electrically connected on the printed circuit board (PCB).
[background technology]
Zero-force connector for socket is widely used in computer realm, is used to electrically connect chip module and printed circuit board (PCB), to realize signal and transfer of data between the two.Prior art has disclosed multiple zero-force connector for socket, the zero-force connector for socket that is disclosed comprises the pedestal that is connected to printed circuit board (PCB), slidably is mounted on cover plate on the pedestal, and drive the drive unit that cover plate is changed between unlatching and closure, and consider that cost problematic drive device system is by plastic shaping.Pedestal is provided with the plurality of terminals accepting groove, corresponding plant plurality of conductive terminals in the terminal containing slot, and cover plate corresponding terminal accepting groove is provided with some through holes.When cover plate was positioned at the enable possition, the through hole that the stitch of chip module passes cover plate inserted in the corresponding terminal containing slot, and at this moment, the stitch of chip module does not contact with conducting terminal, and chip module can be assembled to socket connector with zero insertion force; When the enable possition was converted to make position, corresponding conducting terminal was electrically touched in the stitch of chip module and the terminal containing slot at cover plate, thereby realized electrically conducting between chip module and the printed circuit board (PCB).Wherein, drive unit is to be that rotation drives the cover plate closure or openness to basic point by cam with the pedestal.Intensity for the basic point that guarantees pedestal often is provided with a block substrate on pedestal, be provided with the hole punching of a die-cut formation in this bulk substrate, and cam mechanism system is that rotate at the center with this hole punching, when cam mechanism rotates and the hole punching inwall rub.Form when being die-cut hole punching because of the hole punching inwall, its flatness can not guarantee, and considers that cost and technical problem can not carry out secondary operations yet.The drive unit of plastic material very easily weares and teares when cooperating the back to rotate with this kind hole punching, wearing and tearing back cam mechanism can form the gap between hole punching, the driving process of cover plate can be shortened in the gap that is produced, thereby causes the stitch and the conducting terminal loose contact of chip module.
Therefore, be necessary to propose a kind ofly have the connector of novel matrix to address the above problem.
[summary of the invention]
The object of the present invention is to provide the better and electric connector of drive unit easy to wear not of a kind of operability.
The technical scheme that realizes purpose of the present invention is: a kind of electric connector, it comprises having conducting terminal, insulating body, the cover plate and the drive unit that reciprocatingly slide of insulating body relatively, insulating body is provided with the terminal accommodation holes and the installing hole of accommodating above-mentioned conducting terminal, be provided with slit around the installing hole, be provided with arcwall in the slit, described installing hole and slit connect, cover plate is provided with and above-mentioned terminal accommodation holes and installing hole corresponding through hole of difference and drive hole, drive unit passes rotatable being installed in the installing hole behind the drive hole, wherein, be provided with strip suppor bar and curved shape suppor bar in the described slit, strip suppor bar and curved shape suppor bar comprise first support division and second support division respectively, curved shape suppor bar also comprises hook, hook cooperates with the arcwall of slit, the strip suppor bar is between two hooks, and drive unit contacts with first support division and second support division, drive unit is after drive hole is interfered in the center rotation, to drive cover plate and reciprocatingly slide with respect to insulating body with the installing hole.
Compared with prior art, the present invention has following beneficial effect: when electric connector of the present invention drove cover plate at the operation drive unit, resistance was less, and drive unit is not easy to be worn, and life of product is long.

Fig. 2 is the decomposing schematic representation of electric connector of the present invention;
Fig. 3 is the part exploded view of the insulating body of electric connector.
[embodiment]
Please refer to Fig. 1 to shown in Figure 3, electric connector 100 of the present invention comprises that the insulating body 20 that is connected on the printed circuit board (PCB) (not label), corresponding plurality of conductive terminals 30, the movable group that is placed in the insulating body 20 be located at the cover plate 10 on the insulating body 20, and drives the drive unit 40 that cover plate 10 relative insulating bodies 20 are changed between unlatching and make position.
Please refer to shown in Figure 2ly, insulating body 20 is roughly the rectangular flat shape, comprises the flat part 202 that becomes rectangle substantially, is arranged on the flat part 202 and the plurality of terminals accepting hole 201 of up/down perforation and by the extended installation portion 203 of flat part 202 1 sides.Aforementioned terminal 30 correspondence respectively is contained in the above-mentioned terminal accommodation holes 201.Installation portion 203 includes an installing hole 204 and is positioned at installing hole 204 slit 205 on every side.Be provided with strip suppor bar 61 and curved shape suppor bar 62 in the slit 205.Strip suppor bar 61 has first support division 610, and curved shape suppor bar 62 includes second support division 620 and the holding parts 621 of being located at second support division, 620 two ends.Installing hole 204 both sides are provided with a pair of breach 206, and breach 206 makes installing hole 204 be communicated with slit 205 on direction A.Installing hole 204 both sides are provided with pair of posts 208.Strip suppor bar 61 is arranged in the slit 205 of installing hole 204 belows, and second support division 620 of curved shape suppor bar 62 is arranged in the slit 205 of installing hole 204 tops, and its holding parts 621 is arranged in the slit 205 of installing hole 204 both sides.First support division 610 sees through breach 206 with second support division 620 and is communicated with installing hole 204.The hook of holding parts 621 for extending to form downwards from second support division, 620 two ends of curved shape suppor bar 62, strip suppor bar 61 is between two hooks relative with second support division 620.Can matched in clearance between strip suppor bar 61 and two hooks can also interference engagement.Slit 205 is provided with the camber wall 210 that cooperates holding parts 621 hooks, and camber wall 210 firmly is fastened in holding parts 621 in the slit 205.Slit 205 is seized strip suppor bar 61 stable being fastened in the slit 205 on both sides by the arms with curved shape suppor bar 62.Strip suppor bar 61 is extrusion molding with curved shape suppor bar 62, and its smooth surface coefficient of friction is lower.
During installation, cover plate 10 is covered on the insulating body 20, drive hole 109 corresponding installing holes 204, drive unit 40 pass drive hole 109 rotatable being installed in the installing hole 204.Drive unit 40 is after drive hole 109 is interfered in the pivot rotation, to drive cover plate 10 on the A direction with installing hole 204, and drive unit 40 sees through breach 206 and first support division 610 and second support division, 620 butts.Because of drive unit 40 only drives cover plate 10 in the motion of A direction, so drive unit 40 mainly is subjected to the reaction force of first support division 610 and second support division 620.Because of first support division 610 and second support division, 620 smooth surfaces can reduce and drive unit 40 between coefficient of friction, suffered resistance is less during drive unit 40 rotation, it is also less to wear and tear.When operation drive unit 40 drives cover plate 10, preferable operability, life of product increases.
