Description

Electric connector

[technical field]

The present invention relates to a kind of electric connector, relate in particular to a kind of electric connector that is used for the test chip module.

[background technology]

In order to guarantee chip module security reliability in use, nearly all chip module must be tested before installing and using.Test is that the chip module is carried out long high temperature running, and the chip module that has defective was lost efficacy as early as possible, eliminates thereby defective chip module is screened.Can use safely after being assembled to electronic terminal product through the chip module of testing.

A kind of electric connector related to the present invention, it is used for the test chip module, comprises insulating base, the lid that movably is articulated in insulating base that is installed with some conducting terminals and the crimp that movably is articulated in lid.Insulating base is provided with for the pivot end of pivot joint lid and the fixing end relative with pivot end.Crimp is provided with first end and the second end relative with first end that is articulated in lid, and the second end is provided with grab.During use, rotarily open crimp, can drive lid it is rotarily opened, put into the chip module that to test.Then rotating closed crimp, make lid rotating closed, the fixing end phase clasp of the first end of crimp and insulating base, and the pivot end phase buckle of grab and insulating base, finally make chip module and conducting terminal realize good electric connection simultaneously.

Yet, this electric connector in use, in order easily to pick and place the chip module, crimp will rotate enough large angle makes lid be in opening, due to the development of electronic product towards miniaturization, cause electric connector and the distance between other elements is less on every side, make crimp can collide around other element, make troubles to use.

So, the defective that needs a kind of new electric connector of design to exist to overcome above-mentioned electric connector.

[summary of the invention]

Lid 2 is hollow frame structures of being made by insulating material, and it comprises that rotor is connected in first end 25 and second end 24 relative with first end 25 on insulating base 1.The both sides of first end 25 are provided with a pair of lug 22, and the central authorities of each lug 22 connect and are provided with assembly hole 221.The second end 24 is provided with through hole 241, the first guide rods 23 can be run through and be contained in through hole 241, and the two ends of the first guide rod 23 are provided with the collar 231.During assembling, pivoted pole 21 can be successively by the assembly hole 221 that arranges on the installing hole 121 that arranges on the locking end 12 of insulating base 1 and lug 22, thereby lid 2 is articulated on insulating base 1.

In addition, can more stably press the chip module in order to make lid 2, usually also be provided with replaceable pressing plate 5 on lid 2.Pressing plate 5 is hollow sheeting columnar structure, and it can be connected on lid 2 separably by screw, bolt etc.In actual use, can select suitable lid 2 according to profile and the size of chip module.

Crimp 3 is to be made by metal sheet, and the outside that it is coated on lid 2 comprises that fixing end 32 is connected relative clasp end 33 and connect fixing end 32 and clasp end 33 a pair of by flanging 34 with the fixing end.Crimp 3 bends downwards respectively in the both sides of fixing end 32 and is provided with pin-jointing piece 321, offers perforate 3210 on pin-jointing piece 321.Be provided with kink 341 by flanging 34 near the downward bending in the position of fixing end 32, it is provided with the hypotenuse 3411 towards 33 inclinations of clasp end.The second guide rod 31 can be successively be pivotally connected to crimp 3 by pivoted hole 111 and perforate 3210 pivot end 11 of insulating base 1, and crimp 3 can be in certain scope around the second guide rod 31 with respect to insulating base 1 rotation.The both sides of clasp end 33 are respectively equipped with the protruding wing 331 of pair of curved, be respectively equipped with groove 3310 on the protruding wing 331, connecting rod 72 can pass successively the groove 70 of wearing that the middle position of groove 3310 and grab 7 offers grab 7 is pivotally connected to clasp end 33, and makes the grab 7 can be around connecting rod 72 rotations.

Describe the assembling process of electric connector 100 of the present invention in detail below in conjunction with accompanying drawing.Please consult simultaneously shown in Figure 2, at first kickboard 4 is placed in the accommodation space 14 of the insulating base 1 that contains conducting terminal 6, the through hole 410 and the conducting terminal 6 that arrange on kickboard 4 are corresponding, and the snap close hook 44 of kickboard 4 lower ends settings is held in the groove of insulating base 1 setting; Secondly pressing plate 5 is assembled on lid 2; Then lid 2 is pivotally connected to the locking end 12 of insulating base 1 by pivoted pole 21, and lid 2 can rotate around pivoted pole 21; Afterwards the first guide rod 23 is arranged in again in the pivoted hole 111 of pivot end 11 of insulating base 1; The crimp 3 that grab 7 will be installed at last is connected in the pivot end 11 of insulating base 1 by the second guide rod 31, and lid 2 can rotate between enable possition and make position with respect to insulating base 1.Simultaneously grab 7 can rotate freely around connecting rod 72, when crimp 3 rotates to make position, grab 7 can clasp on the boss 122 of insulating base 1.

Describe the operating process of test connector 100 of the present invention in detail below in conjunction with accompanying drawing.See also Fig. 3 to Fig. 4, at first lid 2 is rotated to the enable possition away from insulating base 1, and the chip module is placed in the receiving space 43 of kickboard 4; Then rotate lid 2 until the pressing plate 5 that is installed on lid 2 is connected to the chip module; Afterwards crimp 3 is rotated to make position, the hypotenuse 3411 that the kink 341 of crimp 3 arranges is crimped on the collar 231 of the first guide rod 23 again.At this moment, kickboard 4 also is in open position, and the chip module that is placed in the receiving space 43 of kickboard 4 not yet contacts with conducting terminal 6, presses down crimp 3 and makes its crimping collar 231, further makes lid 2 rotating closed; Finally rotate grab 7 until it is held on the boss 122 of insulating base 1.At this moment, crimp 3 provides downforce by lid 2 and the pressing plate 5 that is connected on lid 2 to the chip module, kickboard 4 will move down, the through hole 410 that conducting terminal 6 passes base plate 41 settings of kickboard 4 enters receiving space 43, and be electrically connected with the chip module that is carried on kickboard 4, thereby realize the electric connection between chip module and printed circuit board (PCB), the chip module is tested.

After being completed, the grab 7 of crimp 3 is freed from the boss 122 of insulating base 1, kickboard 4 moves up to open position together with the chip module that is placed on kickboard 4 under the effect of reaction force, originally expose kickboard 4 outer and and the conducting terminal 6 that is electrically connected of chip module shrink back again in the through hole 410 of kickboard 4, the electric connection disconnection between conducting terminal 6 and chip module.

Be articulated in respectively the locking end 12 and pivot end 11 of insulating base 1 due to lid 2 and crimp 3, reduced the space that taken when crimp 3 is opened, effectively prevent the phenomenon of other element collisions on crimp 3 and printed circuit board (PCB).
