Existing microprocessor chip is to be electrically connected on the circuit board by electric connector, and it is as " the technical matters method of ball bar array socket " (P460-P466,1996 IEEE 46th Flectronic Components﹠amp; TechnologyConference) disclose, in addition, in order to meet the frivolous trend of connector design, existing electric connector adopts cam or eccentric wheel structure to drive, as United States Patent (USP) the 6th, 250, No. 941,6,254, No. 415,6,280, No. 224,6,296, No. 507 and 6, the structure that is disclosed for 338, No. 640.In addition; United States Patent (USP) the 6th; 338; No. 640 patent discloses the cam-actuated electric connector of a kind of employing; electric connector comprises pedestal, be articulated on the pedestal and relatively the lid that slides of pedestal, be contained in plurality of conductive terminals, the drive member in the pedestal and protect member, drive member is made up of some not coaxial cylinders.The protection member is made up of partition and pad, and partition buries molding mode with edge and is mounted on the lid, and pad is embedded in the groove of pedestal, and the partition middle position is provided with manhole, and pad is provided with the perforation that roughly is square.After this electric connector assembling, drive member wears the through hole of lid, partition, the perforation and the pedestal of pad successively, to reach the driving effect.

Yet; the partition and the pad of protection member are metal material; and the face that the square perforation that the direct punching press of pad forms contacts with drive member is comparatively coarse; thereby the frictional force on drive member and the perforation contact-making surface is bigger; make drive member drive when the relative pedestal of lid slides and need very big operation torsion, operation is inconvenient.Secondly, because pad is contained in the pedestal, the thickness of pad is less than the thickness of pedestal, therefore make pad intensity a little less than.

Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.

[utility model content]

The technical problem that the utility model solved provides a kind of electric connector, and this electric connector can increase gasket strength and can reduce coefficient of friction on actuator and the pad contact-making surface.

In order to solve aforementioned technical problem; the utility model provides a kind of electric connector; it comprises: the matrix of accommodating plurality of conductive terminals; be covered on the matrix and be provided with the lid of some through holes corresponding with terminal in the matrix; be contained in and also can drive actuator and the protection member of lid between matrix and the lid with respect to the matrix parallel slip; described protection member comprises to be located at the partition in the lid and to be located at pad in the matrix, and wherein, described pad is provided with stepped hole.

Compare with correlation technique, the pad of the utility model electric connector is provided with stepped hole, and this stepped hole has smooth side wall, therefore can reduce the coefficient of friction between actuator and the pad, reduces operation torsion; Secondly owing to form thickness and the width that the sidewall of this stepped hole has increased pad, therefore strengthen the intensity of pad, prevented pad distortion or fracture.
