Abstract
An electrical connector comprises an insulation body with a plurality of terminal detaining grooves. A plurality of conductive terminals are respectively detained in the terminal detaining grooves and each terminal comprises at least a base, a fixture part that is positioned on and stretches from the base, an arm that is positioned on and stretches from the side of the base, a winding part that is positioned on and stretches from the arm and forms an angle with the arm, and a contacting part that is positioned on and stretches continuously from the winding part. Wherein the winding part is provided with a cambered surface and the width of the contacting part is larger than the width of the adjacent part between the end of the winding part and the contacting part. When the contacting part misplaces with the conductor of the electrical connector, greater chances that the terminal contacts with the connector are provided, therefore the requirements of the orthophoria degree can be reduced and the measurement of the contacting part of the terminal is more convenient.
Description
[technical field]
The utility model is about a kind of electric connector, 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.
[background technology]
Land grid array package is electrically connected to the electric connector of circuit board, wherein this land grid array package one side is provided with the electric conductor of structure in the form of sheets, this electric connector has lamellar and is connected to the insulating body of circuit board, this insulating body middle part is a conduction region, be equipped with plurality of conductive terminals in conduction region, these conducting terminals have better elasticity and convexedly stretch in outside the insulating body, need insulating body to be applied one and press down external force by other assembly, and make after the conducting terminal generation strain electric conductor of the elastic force extruding land grid array package by conducting terminal, thereby reach being electrically conducted of land grid array package and circuit board.
Yet, because reducing of terminal sizes, particularly terminal and electric conductor width of contact region reduces, thereby termination contact portion and electric conductor touch opportunity are reduced the requirement of terminal normotopia degree is improved, in addition, required for guaranteeing product functionality, when carrying out the measurement of terminal normotopia degree and flatness, because termination contact portion and electric conductor contact area are too small, cause measuring surface too small, measurement equipment understand can't this measurement point of identification or face whether exist.As shown in Figures 1 and 2, for a kind of existing planar lattice array 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, own elasticity portion 6 ' bend 60 ' reduce gradually to contact site 62 ' width.This planar lattice array terminal 9 ' be placed in connector terminals accepting groove 50 ' after, its contact site 62 ' protrude in outside the 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.So, because terminal 9 ' own elasticity portion 6 ' bend 60 ' to contact site 62 ' width reduce gradually, termination contact portion 62 ' area is too small to making, when terminal 9 ' contact site 62 ' with land grid array package 4 ' electric conductor 20 ' cause easily when having dislocation slightly contact site 62 ' with electric conductor 20 ' contact failure, thereby electric connector terminal 9 ' normotopia degree is required to improve.Too small because of measured area simultaneously, measuring equipment can't this measurement point of identification or face whether exist, 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, closely influences 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, when dislocation takes place in the contact site of this electric connector terminal and electric conductor, its can provide terminal and electric conductor greatly touch opportunity will hang down its normotopia degree requirement and to be convenient to measure the terminal contact site.
The utility model is the electric connector about a kind of land grid array package, it comprises the insulating body of tool plurality of terminals accepting groove, several conducting terminals are contained in respectively in the terminal containing slot, the holding parts that each terminal includes base portion, extend to be provided with from base portion one end, extend the arm that is provided with from the afterbody of the terminal vertical extent setting of holding parts, from the base portion side, extend the bend that is provided with and forms with it an angle and continue from bend from arm and extend the contact site that is provided with.Wherein this contact site is a cambered surface setting, and the width of this contact site is terminal greater than bend and the width at the adjacent place of contact site.
Compared with prior art, the utlity model has following advantage: connector terminals is provided with big contact site, when this connector terminals contact site and electric conductor generation dislocation, it can provide terminal and the big touch opportunity of electric conductor to reduce its normotopia degree requirement and to be convenient to measure the terminal contact site.

[embodiment]
See also Fig. 3 to Fig. 8, the conducting terminal 1 of electric connector 2 of the present utility model is used to electrically connect planar grid encapsulation 3 and circuit board 4, and wherein planar grid encapsulates 3 one sides and is provided with electric conductor 30.This conducting terminal 1 includes base portion 10, afterbody 12 and elastic portion 16.Wherein this base portion 10 1 ends extension is provided with holding parts 11, and the width of this holding parts 11 is greater than the width of base portion 10; This afterbody 12 is from the terminal vertical extent of holding parts 11 and go out, and by a tin ball 5 to be soldered on the circuit board 4; This elastic portion 16 is extended setting in a side 13 bendings of base portion 10, which is provided with an arm 160, and this arm 160 is a α angle setting with base portion 10, and this α angle is the best with 145 degree.Be provided with some hangnails 14 in the two sides 13 of holding parts 11, be immobilizated in conducting terminal 1 in the terminal containing slot 24 of insulating body 22 of electric connector 2 electric connector 2.
This elastic portion 16 comprises arm 160, bend 18 and contact site 19.Wherein this bend 18 extends away from base portion in the upper end of arm, because of bend 18 in order to preferable elasticity to be provided, so its width is narrower, in the present embodiment, the width of bend 18 upwards dwindles setting (as shown in Figure 4) gradually from arm 160 is terminal.Wherein this bend 18 further extends the contact site 19 that is provided with arcuation in its free terminal, and the cross-sectional width A of this contact site 19 is greater than the width B of bend 18 ends.When the electric conductor 30 of being located at planar grid encapsulation 3 pushes corresponding with it contact site 19, this contact site 19 will and planar grid encapsulate 30 formation of electric conductor of 3 and electrically conduct, because the cross-sectional width of contact site 19 is bigger, so, even can not normotopia contacting the area and the electric conductor 30 that also have major part contact site 19 when connecting at contact site 19 and electric conductor 30 connects, in addition, because the contact area of contact site 19 is bigger, makes like this and is convenient to measuring equipment to contact site 19 captures when measurement terminal.
