Abstract

The utility model discloses an electric connector and the auxiliary device of the electric connector; the electric connector is provided with a fixing device for fixing the CPU, which can ensure that the CPU is not damaged; besides, the CPU can be in electric connection with the circuit board through the conductive fuzz in the electric connector; the utility model has the advantages of simple production and convenient assembly; besides, the utility model can also decrease the assembly cost.

Description

Electric connector and auxiliary equipment thereof

Technical field

The utility model relates to a kind of electric connector and auxiliary equipment thereof, especially a kind of electric connector and auxiliary equipment thereof that is provided with fixed structure.

Background technology

Type CPU electric connector mainly as shown in Figure 1 for existing connector LGA (land grid array), electric connector comprises insulating body 1 and some terminal 2 and tin balls 3 that is inserted in wherein, this terminal has a welding ends 4 and a contact jaw 5, the welding ends 4 of electric connector communicates to reach electrically with circuit board 6 welding by tin ball 3, its contact jaw 5 contacts with the conductive gasket 8 that CPU7 is provided with, and reaches the compression conducting under the effect of electric connector auxiliary equipment (not icon) press power.But, owing to do not have fixture between this CPU and the electric connector, so, when the auxiliary equipment of electric connector was installed, CPU dropped easily, thereby may damage expensive CPU, not only comprised simultaneously the installation that plugs but also comprised the tin ball of terminal in the assembling process of this electric connector, need when mounted again could reach electric connection with circuit board by welding manner, this just makes that assembling process is more numerous and diverse, has increased the cost of assembling greatly.

Summary of the invention

The purpose of this utility model is to provide a kind of electric connector and auxiliary equipment thereof, can fixation of C PU, do not drop and be damaged making it, guarantee the normal operation of computer.

Another purpose of the present utility model is to provide a kind of electric connector and auxiliary equipment thereof, can simplify the manufacturing process of electric connector simultaneously, and ease of assembly reduces assembly cost.

For achieving the above object, the utility model electric connector and auxiliary equipment thereof, this electric connector is provided with the fixture of fixation of C PU, thereby can guarantee that CPU is not damaged, and this CPU can electrically connect by conduction fine, soft fur in this electric connector and circuit board, it makes simple, and is easy to assembly, can reduce assembly cost.

Embodiment

Below in conjunction with accompanying drawing the utility model electric connector and auxiliary equipment thereof are further detailed.

A kind of execution mode of Fig. 2 when Figure 5 shows that the utility model electric connector and auxiliary equipment thereof are connected with CPU.As shown in the figure, this electric connector comprises an insulating body 10 and some conduction fine, soft furs 12 that is inserted in wherein, this conduction fine, soft fur 12 is made for metal material, has certain elasticity, it comprises on one contact jaw 14 and contact jaw 16 once, contact jaw 14 and 16 protrudes in the upper and lower surface of insulating body 10 respectively up and down, with with CPU20,32 contacts of the conductive gasket 22 on the circuit board 30, at place, both sides one fixed structure 40 is arranged respectively near electric connector, this fixed structure 40 is one " μ " shape sheet metal, its sheet metal two ends are individually fixed in insulating body 10 and circuit board 30, the other end inwardly dashes and sets out a projection 42, with when assembling with the CPU20 buckle, avoid it to drop and damage.During assembling, earlier CPU20 is buckled in the fixed structure 40, radiator 60 (also can be that plate body or other bottom are the part of plate body) then is installed, its fixed form is as follows: use from backboard 50 vertically extending bolts 52 and pass circuit board 30, pass the pedestal 62 of radiator 60 again, then on pedestal 62, CPU20 is fixedlyed connected with backboard 50 with circuit board 30 with electric connector by tightening nuts 54, under the pressure effect at this moment, the contact jaw up and down 14 and 16 of the conduction fine, soft fur 12 of electric connector respectively with CPU20, circuit board 30 closely contacts, and reaches to electrically conduct.Owing to be provided with fixture between this CPU and the electric connector, so, when the auxiliary equipment of electric connector is installed, CPU is had damage and drop, thereby guarantee the normal operation of computer, included only plugging of terminal in the assembling process of this electric connector simultaneously and do not have the installation of tin ball, also need not when mounted to reach electric connection simultaneously by welding manner and circuit board, this just makes that assembling process is fairly simple, greatly reduces the cost of assembling.

Second kind of execution mode of the utility model, as shown in Figure 6, also can suppress bar 58 buckle mutually with arc by card post 56, (all sign) are fixedly connected so that CPU, electric connector, circuit board, can guarantee that equally CPU is not damaged, guarantee the normal operation of computer.

The structure of the utility model electric connector and auxiliary equipment fixation of C PU72 thereof also may be embodied to as shown in Figure 7, it is different from the embodiment described above changes a side " μ " shape sheet metal into one projection 70 that is extended internally by insulating body, when assembling, CPU72 can be withheld too, to guarantee the normal operation of computer.
