Abstract
An electric connector comprises an insulation boy, a plurality of terminals and a lower buckle stand, one end of the lower buckle stand is bended upward and extended to form a first pivoting part, and the upper end of the first pivoting part is bended upward and extended to form two protruding blocks. The two opposite side surfaces of each protruding block are two blocking surfaces, and a limiting space and an upper pinch plate are formed between the two blocking surface, a limiting stopper is protruded in the limiting space corresponding with one end of the upper pinch plate, and the two side surfaces of the limiting stopper are respectively pressed against the two blocking surfaces to preventing the upper pinch plate from moving from the left to the right, and a fixing part is arranged to fix the upper pinch plate. As the limiting space is arranged on the upper end of the first pivoting part and is far away from the bottom surface of the lower buckle stand, and the length of the limiting stopper is reasonable, thus in the process of overturning the upper pinch plate, the limiting stopper will not exceed the bottom surface of the lower buckle stand, and a circuit board arranged on the bottom surface of the lower buckle stand will not be scratched.
Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of in order to chip module is electrically connected to the electric connector on the circuit board especially.
[background technology]
Known chip module borrows electric connector to realize electric connection with circuit board usually, to realize the transmission of data and signal between the two.Described electric connector comprises metal shell and insulating body.Described metal shell comprises upper shell and lower house, and the mid portion of described upper shell and described lower house is all hollowed out, and roughly forms framework.Described insulating body comprises the tabular main body, extends upward the formation leg around the described main body, and described main body and described leg form the space that can accommodate described chip module.
The TaiWan, China patent application has disclosed a kind of electric connector relevant with the utility model No. 97143358, it comprises insulating body, is contained in a plurality of conducting terminals in the described edge body, be located in the metal reinforced sheet of described insulating body periphery, be articulated in described metal reinforced sheet one end in order to compress the pressing plate of described chip module, be articulated in the rocking bar that the described metal reinforced sheet other end can fasten with described pressing plate.Wherein, described metal reinforced sheet one end is provided with draw-in groove, and described draw-in groove both sides are connecting wall.Described pressing plate is provided with relative pivot end and press-side, and described pivot end is provided with holding part and cooperates with described draw-in groove, can make the described relatively metal reinforced sheet of described pressing plate do front and back and lift.
Usually, can pack into and freely rotates in order to make described holding part, described draw-in groove can keep than gap greatly.Therefore, the described pivot end of said structure also is provided with the stopper section, forms holding slot between described stopper section and the described holding part, utilizes described holding slot to cooperate with described connecting wall and limits described pressing plate double swerve, so that described pressing plate is directed to positive direction.Yet, still there is following weak point:
Described electric connector utilizes the described holding slot that forms between described stopper section and the described holding part to cooperate with described connecting wall and limits described pressing plate double swerve, thereby with respect to the electric connector that is not provided with described stopper section, really can play the effect of the described pressing plate double swerve of restriction to a certain extent, but, described pressing plate still has improved space---when skew is turned left or turned right to described pressing plate, described stopper section only supports mutually with the lateral surface of its medial surface and described connecting wall, and the lateral surface of described stopper section handicapping retaining structure not, make described pressing plate still can be freely toward the lateral surface of described stopper section towards direction move, and can not play the effect of essence (promptly preventing described pressing plate double swerve), thereby described pressing plate might collide described metal reinforced sheet or the described insulating body of scratch when fastening, described pressing plate can't be fastened smoothly, finally influence the normal electric connection of described electric connector or described electric connector is damaged.
Thereby another kind of connector has appearred in industry at present, is used to be electrically connected to a circuit board, and described connector comprises: an insulating body; A plurality of terminals are located in the described insulating body; One Button Block, be located in described insulating body periphery, the one end is provided with a pivot end, described pivot end is provided with at least one draw-in groove, described Button Block is provided with at least one groove of placing restrictions on around described pivot end, describedly place restrictions on the bottom surface that groove runs through described Button Block and be provided with, the described groove of placing restrictions on has the two block walls that are positioned at its relative both sides of opening; One fixture is articulated on the described Button Block; An and press box, be covered on described insulating body top, the corresponding described pivot end of described press box is provided with a hub switch side, described hub switch side is provided with at least one holding part and cooperates formation to articulate with described draw-in groove, described hub switch side is provided with at least one stopper section and is positioned at the described groove of placing restrictions on, and the width of described stopper section is identical with described width of placing restrictions on groove to be moved in Width to limit described press box.
So, though described press box can not move in Width, but because the described groove of placing restrictions on runs through the bottom surface that is arranged at described Button Block, thereby in the process of the described press box of upset, describedly place restrictions on that groove may exceed the bottom surface of described Button Block and scratch is positioned at the described circuit board under the bottom surface of described Button Block.
Therefore, be necessary to design a kind of new electric connector, to overcome the problems referred to above.
