Abstract
The utility model discloses an electric connector, comprising a lower shell, an upper shell pin connected at one end of the lower shell and used for movably connecting with the lower shell, a rocker which is movably connected with the other end of the lower shell and is used for closing the upper shell and the lower shell and a seat which is arranged at the bottom of the lower shell and is used for supporting a chip module. Wherein, the lower shell is fixedly connected with a circuitboard, and the lower shell is provided with a fixed sturcture which is used for fixing the radiator on an electric connector. The electric connector of the utility model is simplified operation steps and reduced cost by directly installing the radiator on the electric connector.
Description
[technical field]
The relevant a kind of compression contact electric connector of the utility model refers in particular to a kind of in order to will compress the electric connector that contact-type central processing unit chip is electrically connected to printed circuit board (PCB).
[background technology]
Along with the development that science and technology is maked rapid progress, LGA (Land Grid Array) type promptly compresses contact-type central processing unit chip and has obtained application more and more widely.Need special electric connector on the printed circuit board (PCB) and match with it for this type central processing unit chip is electrically connected to.Introduced a kind of existing LGA type electric connector as shown in Figure 1, it is by forming as the lower part: upper shell 1, lower house 2, insulating body 3, rocking bar 4.During assembling, central processing unit chip 5 is installed on the insulating body 3 that is fixed on the electric connector on the circuit board, and utilizes rocking bar 4 that upper shell 1 and lower house 2 are fastened, thereby realize the electric connection of central processing unit chip 5 and circuit board.In addition, need radiator when considering the central processing unit chip operation and reduce its temperature, generally corresponding fixed structure will be set on circuit board, radiator is fixed on central processing unit chip 5 upper surfaces.
The defective of the prior art is, the directly structure of fixed heat sink device is not set on the electric connector, so need to manufacture and design again in addition the structure of fixed heat sink, and it is connected with circuit board is connected with circuit board, this makes production process become complicated, also brings certain trouble to the user; Simultaneously, because lower house 2 is not fixed on the circuit board, in the fastening process, lower house 2 can be subjected to active force upwards at diagonal position, make lower house 2 bottom surfaces that buckling deformation take place, and then have influence on the base adjacent with lower house 2 upwards buckling deformation also takes place, solder crack takes place in the position of causing base and circuit board to weld mutually, thereby has influence on the electric connection of central processing unit chip 5 and circuit board.
[summary of the invention]
The purpose of this utility model is to provide a kind of electric connector, can radiator be installed directly on it, and the step that simplifies the operation reduces cost.
For achieving the above object, the utility model electric connector includes lower house, be articulated in upper shell that lower house one end is used for flexibly connecting mutually with lower house, be movably connected in the lower house other end be used for the rocking bar of closed upper shell and lower house and be positioned under housing with the base of supporting chip module, wherein, lower house and circuit board are fixedly connected, and lower house is provided with fixed structure, is used for radiator is fixed on electric connector.
Compared with prior art, the utility model electric connector is by directly being fixed on lower house on the circuit board, thereby make that the shell song can not take place to be out of shape when last lower house is stressed, thereby can not have influence on being connected of coupled base and circuit board, thereby guarantee the electric connection of central processing unit chip and circuit board; The utility model electric connector makes in installation process by the structure of fixed heat sink directly is set on lower house in addition, can directly radiator be installed in above the electric connector, has simplified operating procedure, has reduced cost.

Fig. 3 is the utility model electric connector isometric exploded view.
[embodiment]
Below in conjunction with accompanying drawing the utility model electric connector is made and to further specify.
See also Fig. 2, Fig. 3, the utility model electric connector includes pedestal 20 (in the present embodiment for metal shell), and the lid 30 that can flexibly connect with pedestal 20 is used for the rocking bar 40 that pedestal 20 and lid 30 are snapped together, base 10, radiator fastener 70 and backboard 50.
One square hole is arranged in the pedestal 20, wherein be installed with base 10, four holes 201 are arranged all around, and with bolt 7, four installing holes 501,601 that nut 71 sees through respectively on backboard 50 and the circuit board 6 are installed in (also available certainly welding or alternate manner are fixed) on the circuit board 6 with pedestal 20 lockings.Pedestal 20 is provided with articulated section 202 in square hole one side, and so that rocking bar 40 to be installed, rocking bar 40 is that rotating shaft can freely be rotated under external force with articulated section 202.Lid 30 is a square box body structure, and a side is articulated in the connecting portion 204 on the pedestal 20, and there is a buckling parts 302 on the opposite side top, and the centre is an attaching part 303.During closure rocking bar 40, the end 402 withheld on the rocking bar 40 is pressed on the buckling parts 302, and lid 30 and pedestal 20 are fixed together, and attaching part 302 is retained on LGA type central processing unit chip (not icon) in the base 10.Simultaneously corner positions extends upward two installation portions 203 and the two hook portions 204 of being provided with respectively on the pedestal 20, to fix two fasteners 70 (also can only establish an installation portion certainly and hook portion fixes a fastener) respectively.Radiator (not icon) directly can be placed central processing unit upper surface (not icon), by fastener 70 it be withheld and fix.
During installation, can earlier base 10 be welded on the circuit board 6, and then pedestal 20 is installed on circuit board 6, do not interfix between base 10 and the pedestal 20, thereby can avoid during base 10 pedestal 20 heat absorptions too much to influence welding effect between base 10 and the circuit board 6 in welding, and can avoid the distortion of pedestal 20 and have influence on stable connection between base 10 and the circuit board 6.
Certainly, pedestal can directly be welded on the circuit board, also can reach above-mentioned effect.
Compared with prior art, the utility model electric connector is by directly being fixed on pedestal on the circuit board, thereby make that the shell song can not take place to be out of shape when top base is stressed, thereby can not have influence on being connected of coupled base and circuit board, thereby guarantee the electric connection of central processing unit chip and circuit board; The utility model electric connector makes in installation process by the structure of fixed heat sink directly is set on pedestal in addition, can directly radiator be installed in above the electric connector, has simplified operating procedure, has reduced cost.
Certainly, the utility model also is embodied as other form, as without rocking bar, and with other fixed mechanism (as cam drive mechanism) pedestal and lid is fixed; The fixed form that radiator is fixed on pedestal also is not limited to use fastener, also available other multiple mode, as screw fix, bolt lock mechanism is fixing or the like; The also available plastic material of pedestal is made.
