Description

Electric coupler component and cramp thereof

[technical field]

The utility model relates to a kind of electric coupler component and cramp thereof, especially a kind of electric coupler component that electrically connects between chip module and the circuit board of reaching.

[technical background]

CPU (Central Process Unit) connector is widely used on the personal computer.United States Patent (USP) the 5th, 722 is exposed a kind of cpu connector that is used for desktop computer No. 848.This cpu connector also is called zero insertion force (ZeroInsertion Force) connector, and it comprises a matrix, and it is provided with several terminal grooves, all is equipped with butt in each terminal groove.On matrix, be provided with a lid slidably, lid is provided with several perforation, aligns with each terminal groove respectively.A lateral location place in matrix also is provided with a driven unit, moves on matrix to drive lid.Driven unit is a cam structure, is connected with an action bars simultaneously.When action bars was positioned at the upright position, the pin of CPU can pass the hole on the lid under the situation that is not subjected to any power, enter in the terminal groove again.Afterwards, the action bars rotation moves down, and this moment, cam structure also rotated thereupon, and it is mobile on matrix to drive lid simultaneously.And at this moment the CPU that is assembled on the lid also moves with lid, and then finishes electric connection with the terminal in the terminal groove.What more than introduce is the connector that desktop computer is used.

The employed cpu connector of mobile computer, its basic framework is also roughly the same with the structure that aforesaid patent is disclosed, just be subject to the space of mobile computer, aforesaid action bars has then made the driving chip of horizontal into, and its work is also identical with desktop computer with operating principle, so no longer stating more.

United States Patent (USP) announces the 7th, 001, has then disclosed another kind of electric connector No. 197.This connector generally is commonly referred to as LGA (Land Grid Array) connector, mainly is because the usefulness of CPU is more and more high, the Input/Output of its output also with increase.So can't re-use original pins type, and must make contact chip (Pad) formula into.Come ccontaining contact chip by increasing more space like this.And with respect to the change of CPU, the terminal structure on the connector is also along with change.Wherein the contact jaw of terminal is the upper surface that is raised in connector, directly to contact with the contact chip of CPU.

The electric connector that aforementioned the 7th, 001,197 patents relate to does not have lid, does not drive the drive unit of lid yet, and has used a kind of structure of iron plate up and down that is called for short instead.Wherein electric connector is the central authorities that are assembled in down iron plate, and last iron plate then is a side that is articulated in down iron plate rotationally, then is articulated with a depression bar in the opposite side that descends iron plate.After CPU places on the connector, last iron plate toilet cover get off, re-use at last depression bar last iron plate clinching on following iron plate, electrically contact with the LGA terminal of guaranteeing CPU and connector contact-making surface.

The electric connector of this LGA aspect when being used in desktop computer, because the space is enough, without any problem, but when being used on the mobile computer, just cannot use the depression bar structure of rocker-type.

In addition, also having another problem to need to consider, is the basic framework of CPU.CPU is made of a substrate (Substrate) and brilliant element module (Die) formed thereon.Brilliant element module protrudes from the substrate.So, when CPU is pressed to electric connector, must be distributed in downforce equably on brilliant element module and the substrate on every side.Because descend piezocrystal element module or substrate individually, then all might cause CPU distortion warpage because of stressed inequality, have influence at last and be electrically connected characteristic.

In addition, having a problem to be worthy of consideration again, is the structure of heat abstractor, and general heat abstractor volume ratio is bigger, is square shape body, is made up of the some heating panels on a base plate and the base plate.The heat abstractor of this structure is because volume is bigger, and is passable when being used in desktop computer, but will be used on the mobile computer time, because the space of mobile computer is limited, so the heat abstractor of this structure just has been not suitable for.

Given this, be necessary to provide a kind of improved electric coupler component, to overcome the defective of above-mentioned electric coupler component at the problems referred to above.

[utility model content]

The technical problem that the utility model solved provides a kind of electric coupler component with cramp, and this electric coupler component takes up room little, and described cramp can be assembled at last on the electric coupler component when avoiding earlier the assembling cramp it is had a negative impact.

In order to solve the problems of the technologies described above, the utility model provides a kind of cramp of electric coupler component, can be used for chip module is held in the electric connector, wherein said cramp comprises the two separation cramps that are oppositely arranged, described separation cramp comprises fixed part, from elastic arm and the extended auxiliary section of own elasticity arm that fixed part extends, described two separate cramps by the mutual buckle in auxiliary section.

In order to solve the problems of the technologies described above, the utility model provides a kind of electric coupler component, can be in order to electrically connecting chip module and circuit board, it comprise in order to the electric connector of accommodating chip module, be located at the electric connector top radiating subassembly, cooperate with radiating subassembly and radiating subassembly applied cramp and the connector that downward button is held power.Wherein, described cramp comprises the pair of separated cramp, and each separates the auxiliary section that cramp comprises that the elastic arm that can be fixed in fixed part on the circuit board by connector, extend from fixed part and own elasticity arm extend, and this hands over button to separating cramp mutually by the auxiliary section.

Compare with correlation technique, electric coupler component of the present utility model has the following advantages: at first, cramp takes up room little, can use on notebook computer; Secondly, cramp of the present utility model has the pair of separated cramp, described separation cramp has the auxiliary section, can separate the cramp friendship with two by the auxiliary section is buckled together, so cramp can be assembled at last in the electric coupler component or with radiating subassembly and fit together, be assembled in the electric coupler component, when avoiding cramp elder generation assembly, assembling has a negative impact as warpage to this cramp etc. behind the radiating subassembly again.
