Arrangements of electric connection

[technical field]

The utility model relates to a kind of arrangements of electric connection.

[background technology]

Fig. 1 has disclosed a kind of arrangements of electric connection that is connected central processing unit to motherboard with Fig. 2, wherein Fig. 1 is the stereogram of this arrangements of electric connection, Fig. 2 is the cutaway view of B-B direction shown in Figure 1, this arrangements of electric connection comprises a pedestal 7, be mounted on the slip lid 8 on the pedestal 7 and be installed in slip lid 8 and pedestal 7 in a drive unit 9.Wherein, described pedestal 7 is made by plastic material, and the one end is provided with a hole 70, and in addition, pedestal 7 is provided with most accepting grooves (not shown), to accommodate conducting terminal (not shown); 8 pairs of described slip lids should seat hole 70 the position be provided with a lid hole 80, in addition, the slip lid bottom is concaved with a groove (not shown), is used for accommodating drive unit 9 parts; Drive unit 9 comprises an actuator 90 and an impeller 91, actuator 90 comprises a biasing post 900 and is positioned at its terminal cylinder 901, impeller 91 is provided with two jig arm (not shown), this two jig arm is clipped in the middle biasing post 900, so that can driving impeller 91, moves actuator 90, and impeller is installed in the groove that slip lid 8 bottoms are arranged with (not shown), moves thereby can drive slip lid 8.Other first cylinder is provided with an application of force groove 904, rotates this actuator 90 for aid (not shown).When the assembling central processing unit, this arrangements of electric connection by an aid for example bottle opener (not shown) rotate this actuator 90, at this moment, actuator 90 is positioned at the effect of the hole wall generation power in terminal 901 pairs of seat holes 70 of cylinder, it is the effect that 90 pairs of pedestals of actuator 7 produce power, actuator 90 biasing posts 900 drive impeller 91 and move, impeller 91 promotes slip lid 8 moving along the arrow C direction, thereby the pin on the promotion central processing unit (not shown) moves along the arrow C direction, thereby makes central processing unit (not shown) be installed on this arrangements of electric connection.

Yet, along with electronic product constantly to lightening, miniaturization and portable development, simultaneously, people are also more and more higher to the requirement of the function of computer treatmenting information and arithmetic speed, this just need be provided with more conducting terminal so that upward the more pin of relative set (not shown) is corresponding with central processing unit (not shown) on the limited area of arrangements of electric connection pedestal, like this, the pin of central processing unit (not shown) just increases greatly with the power that conducting terminal (not shown) grafting cooperates, thereby slip lid 8 promotes the also increase greatly of power that the pin (not shown) of central processing unit moves, impeller 91 promotes the also increase greatly of power that slip lid 8 moves, use aid to drive the also increase greatly of power that actuator 90 moves to promote impeller 91, and because actuator 90 has power between the hole wall in the cylinder 901 of end and 7 holes 70 of pedestal interaction, thereby interactional power also increases between them, if the power that aid is applied on 90 of the actuators is excessive, pedestal 7 power of being born just might surpass its scope that can bear so, and an end that makes pedestal 7 be provided with a hole 70 breaks.Take place for fear of this phenomenon, the thickness that can increase pedestal 7 disperses these power, if but the thickness of pedestal 7 is too thick, pedestal 7 inside inevitably will produce bubble in the process of manufacturing, and thickness is big more, and the bubble of generation will be many more, when arrangements of electric connection being positioned in the hot environment welding tin ball, the bubble expanded by heating also breaks, thereby also will cause pedestal 7 to break.

Therefore, be necessary to design a kind of new arrangements of electric connection, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of arrangements of electric connection that prevents that pedestal from breaking.

The utility model arrangements of electric connection comprises: a substrate, and described substrate one end is provided with a datum hole; One pedestal is located on the described substrate, and described pedestal is provided with most accepting grooves, offers the corresponding above-mentioned datum hole in a hole on the described pedestal; Multi-conducting terminals, correspondence are positioned at described accepting groove; One lid, described lid offer corresponding described seat hole, a lid hole along the described pedestal of a sliding stroke buckle on the described lid; An and actuator, described actuator has one first cylinder position and is located in described datum hole and the described seat hole, and at least with this datum hole for cooperating the location, this first cylinder extends upward second an eccentric relatively cylinder, described second cylinder cooperates the location with described lid hole.

The utility model arrangements of electric connection is by being provided with a datum hole on substrate, and make first cylinder cooperation of actuator be positioned described datum hole, make substrate and pedestal bear the thrust of actuator jointly, thereby the bad phenomenon that can avoid pedestal to break such take place.
