Description
[technical field]
The utility model refers to a kind of planar lattice array (Land Grid Array) electric connector that land grid array package is electrically connected to circuit board especially about a kind of electric connector.
[background technology]
The LGA electric connector is used for land grid array package is electrically connected to circuit board, land grid array package one side is provided with the electric conductor of structure in the form of sheets, this LGA electric connector generally has lamellar and is connected to the insulating body of circuit board, this insulating body middle part is a conduction region, be equipped with conducting terminal in conduction region, this conducting terminal have better elasticity and the part convexedly stretch in insulating body outside, when conducting terminal and land grid array package connect, borrow one to push that external force makes conducting terminal generation strain and elasticity is connected to the electric conductor of land grid array package, thereby reach being electrically conducted of land grid array package and circuit board.
Yet because terminal sizes is less, the width of special contact zone is less, so the normotopia degree between contact site and electric conductor is had relatively high expectations.In the practical set process, because the restriction of aspects such as electric connector and land grid array package size, make the requirement of the normotopia degree that is difficult between the electric conductor of the contact site of terminal and land grid array package to reach higher, and cause contact site to be partial to a certain side of electric conductor, promptly making only has less overlay region between contact site and electric conductor, this will have a strong impact on the connection reliability and the signal transmission performance thereof of contact site and electric conductor.As shown in Figure 1 to Figure 3, for a kind of existing LGA terminal 9 ', it comprise be immobilizated in electric connector insulating body 3 ' terminal containing slot 50 ' in base portion 8 ' and from the extended afterbody 7 of this base portion ' with elastic portion 6 ', wherein this elastic portion 6 ' be provided with bend 60 ' and contact site 62 ', in order to guarantee terminal elasticity.This LGA terminal 9 ' be placed in connector terminals accepting groove 50 ' after, its junction 62 ' protrude in electric connector surface.
Land grid array package 4 ' lower surface be provided with electric conductor 20 ', after land grid array package 4 ' be connected to electric connector, electric connector terminal 9 ' contact site 62 ' with electric conductor 20 ' contact.Yet, because terminal 9 ' contact site 62 ' width less, and because electric connector 20 ' and the restriction of aspects such as land grid array package 4 ' size, make contact site 62 ' deflection electric conductor 20 ' a side and cause the less overlay region of contact site 62 ' and electric conductor 20 ' only have, thereby influence contact site 62 ' and electric conductor 20 ' connection reliability, and because electric connector terminal 9 ' and the too small contact position resistance that causes of land grid array package a 4 ' contact-making surface is excessive, and then influence the performance that connects of land grid array package and circuit board.
So, be necessary to design a kind of novel electric connector, overcome above-mentioned defective.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and the contacted electric connector of middle position of the electric conductor of a kind of contact site that can guarantee electric connector terminal and land grid array package particularly is provided.
The utility model is about a kind of electric connector of land grid array package, be used to electrically connect the land grid array package of tool electric conductor to circuit board, it is provided with the insulating body of tool terminal containing slot and is contained in conducting terminal in the terminal containing slot, the flexure strip that this conducting terminal is provided with base portion and goes out from the bending of base portion side.This flexure strip is provided with support chip and is located at the elastic portion of support chip one end, this elastic portion comprise extension that an end of self-supporting sheet extends obliquely, be located at the free-ended contact site of elastic portion and be in extension and contact site between bend.Wherein this contact site is a cambered surface setting, and the center line of contact site has an angle in the horizontal direction with the center line of extension and contacts with the middle position of the electric conductor of land grid array package to guarantee contact site.

[execution mode]
See also Fig. 4 and Fig. 6, electric connector 2 of the present utility model is used to electrically connect planar grid encapsulation 3 and circuit board 4, it comprises insulating body 22, this insulating body 22 is provided with terminal containing slot 24, and be contained in conducting terminal 1 in the terminal containing slot 24, wherein, planar grid encapsulates 3 one sides and is provided with electric conductor 30.
The holding parts 11 that conducting terminal 1 comprises base portion 10, extend downwards from base portion 10, the afterbody 12 that holding parts 11 terminal horizontal are bent to form and the flexure strip 13 that goes out from a lateral buckling of base portion 10.Wherein the both sides of holding parts 11 are respectively equipped with first hangnail 110 and second hangnail 112.Flexure strip 13 comprises connecting portion 14, in support portion 15 that vertical direction extends and be connected with the elastic portion 16 of 15 1 ends in the support portion, wherein flexure strip 13 is connected with a side in base portion 10 by connecting portion 14, and this connecting portion 14 tools one bending makes between flexure strip 13 and the base portion 10 and is formed with an angle.Elastic portion 16 comprises that again bending is connected with in the support portion 15 an end and the extension 17 that extends obliquely, is connected with in the bend 18 of extension 17 1 ends and bending obliquely and is in the contact site that is arcuation 19 of the end of elastic portion 16, and this contact site 19 is with respect to the side level bending of extension 17 to accepting groove 24.Fig. 5 is the vertical view of conducting terminal 1, and line a is the center line of extension 17, and line b is the center line of contact site 19 and since contact site 19 with respect to extension 17 and bend 18 to a lateral buckling, make two center line a, b not overlap, but have an angle c.
Please in conjunction with reference to figure 6 and Fig. 7, conducting terminal 1 is contained in terminal containing slot 24, the base portion of conducting terminal 1 is close to a sidewall of terminal containing slot 24, the sidewall interference of first hangnail 110 of holding parts 11 and second hangnail 112 and terminal containing slot 24 is to be immobilizated in terminal containing slot 24 with conducting terminal 1, the afterbody 12 mats one tin ball 5 of conducting terminal 1 is welded in circuit board 4, the contact site 19 of conducting terminal 1 stretches out the upper surface of insulating body, and the electric conductor 30 of planar grid encapsulation 3 connects with contact site 19 mutually in the mode of pressing down.Because the restriction of aspects such as electric connector 2 and land grid array package 3 sizes, make electric conductor 30 be not be in terminal containing slot 24 directly over, a but side of deflection terminal containing slot 24, which can observe definite by assembling and specifically be partial to side, behind the deviation position of determining electric conductor 30, promptly can be with its contact site 19 bendings one angle c when conducting terminal 1 blanking, contact site 19 is after bending an angle c, when combination, the contact site 19 of conducting terminal 1 is connected mutually with the central part of the electric conductor 30 of land grid array package 3, thereby guarantee that contact site 19 and electric conductor 30 have bigger contact area between the two.Contact site 19 processes of bending conducting terminal 1 are simple, and other size that need not change land grid array package 3 and electric connector 2 just can guarantee well the connecting property of 30 of contact site 19 and electric conductors.
