Description
[technical field]
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used for connecting a chip component on the circuit board that is installed on.
[background technology]
The central processing unit that uses in the computer (CPU) generally is connected to circuit board by an electric connector that is welded on the circuit.This electric connector has an insulating body usually, wherein plugs several conducting terminals.When being placed into CPU on the insulating body, the end pin of CPU bottom contacts with conducting terminal and can produce electric connection.In addition, electric connector also has a locker usually and is used for fixing CPU.
United States Patent (USP) has disclosed a kind of electric connector that is used for connecting CPU No. 7033198.This electric connector is assembled on the circuit board, and it comprises the insulating body that is used for carrying CPU, a lid of pushing CPU, and the L shaped driving lever that lid is pinned.In the time of on being pressed in CPU under the lid, the rotation driving lever makes driving lever one end by being pressed on the lid, and the other end of driving lever is caught on by a base plate.Though the electric connector that above patent discloses can be realized the fixing of CPU, yet has individual defective to be that driving lever presses down in the process in rotation, its end can touch circuit board surface.Because driving lever adopts metal material usually because of requirement of strength, so the sharp-pointed end of driving lever may damage circuit board surface, even hurts the circuit in the circuit board, thereby causes the circuit board disabler.
Therefore, necessary existing electric connector is improved to overcome the defective of prior art.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector that prevents driving lever damage circuit board.
The utility model electric connector is achieved through the following technical solutions: a kind of electric connector, it comprises insulating body, is housed in the plurality of conductive terminals in the insulating body, the lid that is positioned at the insulating body top and the driving lever that matches with lid, one end of driving lever is provided with operating portion, is arranged with sleeve pipe on the operating portion.
According to above technical scheme,, can prevent that the driving lever end from touching and damaging circuit board owing to be with sleeve pipe on the operating portion on the driving lever.
Another beneficial effect of above technical scheme is: be with sleeve pipe on the operating portion, the operator can be provided more comfort feel.
The utility model electric connector can also be realized by another technical scheme: a kind of electric connector, be assembled in and be used to connect a chip component on the circuit board, it comprises a driving lever that is used for the snap close chip component, be arranged with sleeve pipe on the driving lever, when driving lever when circuit board presses down, sleeve pipe can touch circuit board prior to the driving lever end.
According to above technical scheme, sleeve pipe can touch circuit board prior to the driving lever end, can stop driving lever further to be pushed downwards, thereby can prevent that the driving lever end from touching and damaging circuit board.

[embodiment]
Ginseng Fig. 1 to Fig. 3, electric connector 1 of the present utility model is used for being assembled on the circuit board 8, in order to connect a chip component (not shown).Emphasis is with reference to Fig. 3, and electric connector 1 comprises insulating body 2, is housed in the plurality of conductive terminals 3 in the insulating body 2, the lid 4 that is positioned at the insulating body top and the driving lever 5 that matches with lid 4.
Insulating body 2 roughly is square, in order to carry chip component.Conducting terminal 3 wherein can form with chip component and electrically connect.Insulating body 2 one ends have a fixture 6 that is fixed on the circuit board 8, and driving lever 5 is rotatably connected on the fixture 6.Driving lever is L-shaped, and the part that articulates with fixture 6 is a rotating shaft 50.Rotating shaft 50 middle parts are provided with a protuberance 51, and an end of lid 4 is connected on the protuberance 51.Driving lever 5, can be driven lid 4 earlier and rotate together when closure state rotates by opening.When lid 4 roughly covers on the insulating body 2, be rotated further driving lever 5, the protuberance 51 of driving lever 5 can promote lid 4 and laterally move.The other end of lid 4 has a tongue 40, has a breach 41 on the tongue 40, on the circuit board 8 to fixing a screw 9 by breach 41.When lid 4 is promoted by driving lever 5 and horizontal when mobile, screw 9 can snap in the breach 41 of lid tongue and lid 4 is fixing.
Join Fig. 4 and Fig. 5 in the lump, have the operating portion 52 of a bending on the driving lever 5 with an end of rotating shaft 50 perpendicular parts, can be convenient to the user and use manual manipulation.Further be with a sleeve pipe 7 on the operating portion 52.The material of sleeve pipe 7 is softer, can be soft plastic etc.Sleeve pipe 7 also has certain thickness simultaneously.When the user operated, because sleeve pipe 7 is softer, the contact-making surface with finger increased simultaneously, therefore can provide the user comfort feel.The end of operating portion 52 is provided with holding part 53, and holding part 53 passes sleeve pipe 7, and promptly sleeve pipe 7 does not cover holding part 53 simultaneously.Lid 4 one side ends have a trip 42 corresponding to holding part 53, and after driving lever 5 pressed down, holding part 53 was held by trip 42 buttons, thereby lid 4 is pinned.In traditional design, because the user when circuit board 8 is pushed driving lever, can't accurately control the volume under pressure of driving lever, so often driving lever can touch circuit board, the end that driving lever is sharp keen may damage circuit board surface.So in the utility model, because the existence of sleeve pipe 7 makes sleeve pipe 7 itself to touch circuit board 8 and to stop the end of driving lever 5 to touch and damage circuit board 8 prior to driving lever 5.
More than be preferred forms of the present utility model, yet scope of patent protection should be as limit.As the framework that uses the electric connector of driving lever design itself has variedly, and it all can be applied to creative ideas of the present utility model wherein.
