Abstract
The utility model relates to an electric connector which comprises a base, a cap body assembled on the base and a drive component furnished between the base and the cap body. The base is provided with a base hole accepting the drive component, wherein, a groove is arranged at least on the base hole along the base slippage direction vertical to the cap body. The groove accepts a protection fitting provided with a glossy surface contacting the drive component. When the drive component is operated to drive a cap body to slide relative to the base, the base accepting the protection fitting and the protection fitting provided with the glossy surface contacting the drive component lead the friction factor of the glossy surface to be lower and lead to a drop-off in the friction force of a contact surface, thus the drive component is more convenient to handle so as to help the slippage of the cap body relative to the base and ensure the stability of the electric property transmission.
Description
[technical field]
The utility model is about a kind of electric connector, especially refers to a kind of electric connector that electrically connects the wafer module to circuit board.
[background technology]
Existing wafer module is to be electrically connected on the circuit board by electric connector, and it is as " the technical matters method of ball grid array socket " (P460-P466,1996IEEE 46th Electronic Components; Technology Conference) disclose, in addition, in order to meet the frivolous trend of electric connector design, existing electric connector adopts cam or eccentric wheel structure to drive, as United States Patent (USP) the 6th, 250,941,6,254,415,6,280,224,6,296,507 and 6, the structure that is disclosed for 338, No. 640.In addition; the 2559117Y patent of Chinese patent bulletin discloses the cam-actuated electric connector of a kind of employing; electric connector comprise that pedestal, lid are connected 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 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 pad directly forms through punching press contacts with drive member is comparatively coarse; thereby the frictional force on drive member and the pad perforation contact-making surface is bigger; making drive member drive needs very big operation torsion when the relative pedestal of lid slides; operation is inconvenient, and then also can influence the stability between electric connector electric connection wafer module and the printed circuit board (PCB), makes that the telecommunication transmission is unstable.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, can avoid the coefficient of friction on the contact-making surface of drive member and guard member excessive, and then the electric connector that this contact-making surface frictional force is obviously reduced.
The purpose of this utility model is achieved in that a kind of electric connector; comprise pedestal, be mounted on the lid of pedestal and be installed in pedestal and lid between drive member; pedestal is provided with the seat hole of accommodating drive member; wherein; pedestal seat hole offers groove to being less than perpendicular to lid along the direction of pedestal slippage, and the guard member with the shiny surface that contacts with drive member is contained in this groove.
Compared with the prior art; the utlity model has following advantage: when the relative pedestal of operation drive member driving lid slides; owing to contain guard member in the pedestal; guard member has the shiny surface that contacts with drive member; this shiny surface coefficient of friction is less, and contact-making surface frictional force is obviously reduced, and makes that the operation drive member is more convenient; thereby be beneficial to the relative pedestal slip of lid, guaranteed the stability of electrical transmission.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model electric connector.
Fig. 2 is that drive member and protection member are installed in the three-dimensional combination figure of pedestal in the electric connector shown in Figure 1.
Fig. 3 is the three-dimensional combination figure that drive member and guard member are installed in pedestal in the electric connector shown in Figure 1.
Fig. 4 is the three-dimensional combination figure that guard member is mounted on pedestal in the electric connector shown in Figure 1.
Fig. 5 is the three-dimensional combination figure of electric connector shown in Figure 1.
[embodiment]
See also Fig. 1 to shown in Figure 5; the utility model electric connector 2 is to be used for accepting wafer module (not shown) and to be incorporated on the circuit board (not shown); electric connection between wafer module current-carrying part and circuit board corresponding circuit is provided, and it comprises pedestal 20, lid 22, conducting terminal (not shown), drive member 26 and protection member 21.
When operation drive member 26 driving lids 22 relative pedestals 20 slide; owing to contain guard member 24 in the groove 204 of pedestal 20; this guard member 24 has the shiny surface 242 that contacts with drive member 26; these shiny surface 242 coefficient of frictions are less; can prevent effectively that thus drive member 26 is excessive with the coefficient of friction on guard member 24 contact-making surfaces; contact-making surface frictional force is obviously reduced; make that operation drive member 26 is more convenient; thereby have in lid 22 relative pedestals 20 slips, guaranteed the electrically stability of transmission of electric connector 2.
Need to prove that the above embodiment only is a preferred embodiment of the present utility model, other any improvement conversion of carrying out on the present embodiment basis also should not break away from the technical solution of the utility model.The variation of any equivalence that those of ordinary skills take the technical solution of the utility model by reading the utility model specification is the utility model claim and contains.
