Description

Electric coupler component

[technical field]

The utility model refers to the electric coupler component of a kind of electric connection chip module (CPU) to printed circuit board (PCB) especially about a kind of electric coupler component.

[background technology]

Cpu connector is widely used on the personal computer.Use type computer on the table, then generally see United States Patent (USP) the 5th, 722, expose a kind of connector that is used in desktop PC No. 848.This cpu connector also is called zero insertion force (Zero Insertion Force) connector.It has comprised a matrix, and it is provided with most terminal grooves, all is equipped with butt in each terminal groove.On matrix, be provided with a lid in addition slidably, lid is provided with most perforation, aligns with each terminal groove respectively.A lateral location place at matrix still 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 not be subjected to pass under the situation of any power the hole on the lid, enters 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 has finished and be electrically connected with the terminal in the terminal groove.What more than introduce is the connector that desktop PC is used.

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

United States Patent (USP) 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 be because the usefulness of CPU is more and more high, its I/O also increases thereupon.Therefore original pins type can't be re-used, and contact chip (Pad) formula must be made into.So, can increase more space and come ccontaining contact chip.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 ' 197 patents relate to does not have lid, does not drive the drive unit of lid yet, and has used a kind of structure that is called upper and lower iron plate 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, and at the opposite side that descends iron plate, then is articulated with a depression bar.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 connector of this LGA aspect when using on the table the type computer, because the space is enough, without any problem, but when using on mobile computer, just cannot use the depression bar structure of rocker-type.

In addition, also having another problem to consider, is exactly the basic framework of CPU.CPU is made of a substrate (Substrate) and the brilliant element module (Die) that forms thereon.Brilliant element module is to protrude on substrate.Therefore, when CPU is pressed to connector, must be evenly distributed in downforce 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.

Given this, be necessary to provide a kind of improved electric coupler component in fact, to overcome the defective of above-mentioned electric connector.

[utility model content]

[embodiment]

As Fig. 1 and Figure 2 shows that the utility model electric coupler component (not label) and chip module 50, circuit board 70, the three-dimensional exploded view of two different visual angles of backboard 80, electric coupler component comprise the insulating body 10 that is installed with conducting terminal 90, lie against the conducting strip 100 on the chip module 50, but fixing chip module 50 also is resisted against retaining frame 20 on the conducting strip 100, press on the elastic fastening plate 30 that also can be connected to circuit board 70 on the retaining frame 20 by connector 60, be placed on the retaining frame 20 and radiating tube 40 between a pair of elastic fastening plate 30 and connector 60.

As Fig. 1, Fig. 3 and shown in Figure 6, insulating body 10 is provided with continuing surface 101, installed surface 102 and the vertical sidewall 103 around continuing surface 101 relative with continuing surface 101.Sidewall 103 is concaved with mating groove 104, and wherein mating groove 104 extends to installed surface 102.Retaining frame 20 is made for metal, is provided with main part 201, runs through the window 202 of main part, a pair of projection 203 that autonomous body 201 extended upward and be positioned at window 202 both sides, autonomous body 201 extends to form downwards and be positioned at the boss 206 of window 202 peripheries and hook portion 204 and holding section 205 that autonomous body 201 middle side edge and both ends extend to form downwards.Hook portion 204 is the setting of L shape, and it is provided with vertically extending connecting portion (not label) and from the terminal inside horizontally extending buckling parts (not label) of connecting portion.

Elastic fastening plate 30 is made for metal as shown in Figure 3, and it is provided with arcuation base portion 301 and bends the U-shaped connection terminal 302 of extending to two ends from base portion 301.Base portion 301 is provided with the location hole 3011 corresponding with projection 203, and connection terminal 302 is provided with a pair of joining hole 3021 that above-below direction runs through, and this differs to joining hole 3021 pore sizes.Circuit board 70 and backboard 80 are equipped with the through hole (not label) corresponding with joining hole 3021.

See also Fig. 3 to Fig. 5, during assembling, earlier chip module 50 is mounted in the insulating body 10, again flat conducting strip 100 is kept flat and is pasted on the chip module 50, then retaining frame 20 is assembled to insulating body 10, the holding section 205 of retaining frame 20 holds mutually with the sidewall 103 of insulating body 10, hook portion 204 can make up with mating groove 104, boss 206 will press on (as shown in Figure 4) on the conducting strip 100, next elastic fastening plate 30 is seated on the retaining frame 20, the projection 203 of retaining frame 20 passes the location hole 3011 of elastic fastening plate 30 to form the location, elastic fastening plate 30 passes the joining hole 3021 that connection terminal 302 is provided with successively by connector 60, thereby the through hole that circuit board 70 and backboard 80 corresponding joining holes 3021 are provided with is connected to circuit board 70, at this moment, the base portion 301 of elastic fastening plate 30 will be exerted pressure to the main part 201 of retaining frame 20, this pressure successively by retaining frame 20 be passed to conducting strip 100 again to chip module 50 again to conducting terminal 90, at last radiating tube 40 is installed on the retaining frame 20, radiating tube 40 will contact with conducting strip 100.

Above-mentioned elastic fastening plate 30 is connected in circuit board 70 processes, because the hook portion 204 that retaining frame 20 is provided with is combined with the mating groove 104 of insulating body 10, thereby it is not enough and cause retaining frame 20 perks, influence chip module 50 perks or situation not in place is installed to prevent that holding section 205 and sidewall 103 from holding power.And it is more convenient during assembling.

The above only is a kind of execution mode of the present utility model, it or not whole execution modes, the variation of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
