Description

The socket of central processing unit

Technical field

The utility model relates to a kind of socket of central processing unit, particularly relates to a kind ofly having structure and simplifying, be easy to installing, and can reach the socket of the central processing unit of the reliable practicality structural design of contact contact stabilization.

Background technology

Power connection end of the central processing unit of integrated circuit device (CPU) can be divided into pin lattice array (Pin Grid Array according to the difference of structure, abbreviation P.G.A), ball form battle array (Ball Grid Array, be called for short B.G.A) and three kinds of field lattice arrays (Land Grid Array is called for short L.G.A) etc.;

Wherein.United States Patent (USP) the 5th, 456, No. 613, it is central processing unit at pin lattice array (P.G.A) formula, it provides special-purpose socket structure, yet because power connection end of the integrated circuit of pin lattice array is very long, must be by the very high conductive member of setting-in in the very thick insulated receptacle, could contact with power connection end of pin lattice array integrated circuit device and the conductive junction point of printed circuit board (PCB) respectively, so it is very big that this kind specialized in the thickness of socket structure of pin lattice array central processing unit, can't satisfy compact demand.

For this reason, industry develops and to be exclusively used in ball lattice array (B.G.A) central processing unit that can reduce the sub-length of power connection end, it is that long pin power connection end of the central processing unit of pin lattice array (P.G.A) is made into ball lattice type, for example tin ball or copper ball, power connection end of central processing unit is shortened significantly, and the private jack that United States Patent (USP) designs at ball lattice array (B.G.A) central processing unit for the 5th, 419, No. 710 exactly.

And more simplify for power connection end that can make central processing unit, develop again in recent years and field lattice array (L.G.A) integrated circuit device, its power connection end then makes the field trellis of flat thin flat into, makes structure more simple, manufacturing cost is lower, and contact and conductive effect are better, and for example United States Patent (USP) the 5th, 192, No. 213, the 5th, 199, No. 889, the 5th, 232, No. 372, the 5th, 320, No. 559, the 5th, 362, No. 241 and the 5th, 389, No. 819 promptly is to provide various heteroid sockets respectively at this farming lattice array (L.G.A) integrated circuit device.

Above-mentioned design is in order to dwindle the area of integrated circuit device, pitch between its any adjacent two power connection end is also done more and more narrowly, and it is more and more denser, and will be under so narrow pitch, remove to insert the conductive member of embedding integrated circuit device bottom, originally promptly belong to and being difficult for, if also require conductive member can have enough elastic momentums up and down, then the telescopic springing part of conductive member has only towards extending perpendicular to the sub-face of the power connection end of integrated circuit device aspect, so the thickness of existing socket is all very thick, and towards the springing part that extends perpendicular to the sub-face direction of integrated circuit device power connection end, make its structure become more complicated, and can't produce enough elastic momentums, for this reason, and application case number No. 91206631 " the big elastic momentum conductive member of integrated circuit socket " be arranged, can make springing part become longer, the design that elastic momentum becomes bigger proposes, precisely because shortcoming is, the conductive member of big elastic momentum is compressed by power connection end of integrated circuit device bottom, is easy to generate elastic fatigue and influences and connect electric effect.

This shows that the socket of above-mentioned existing central processing unit obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.The problem that exists for the socket that solves central processing unit, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.

Because the defective that the socket of above-mentioned existing central processing unit exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, socket in the hope of the central processing unit of founding a kind of new structure, can improve the socket of existing central processing unit, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
