[embodiment]
With reference to Fig. 1 and Fig. 2, the arrangements of electric connection 1 of first embodiment of the invention is for connecting a chip module 2, and it mainly comprises circuit board 3 and is assembled in the some conducting terminals 4 in circuit board 3.Circuit board 3 is provided with some terminal holes 30 that run through its thickness direction, on the inwall of terminal hole 30, have conductive layer 31 with circuit board in signal path 32 phase electrical communication.Conducting terminal 4 is contained in respectively in terminal hole 30, and with wherein conductive layer 31 is in electrical contact.
Emphasis is with reference to Fig. 2 and Fig. 3, and conducting terminal 4 comprises signal terminal and earth terminal (not indicating respectively), and two kinds of terminal structures are identical.Each conducting terminal 4 comprises a base portion 40, the contact site 41 and the support portion 42 that by base portion 40, are tilted to extend up and down respectively and is positioned at base portion 40 both sides and vertically extending holding parts 43.Holding parts 43 contacts with conductive layer 31 and conducting terminal 4 is retained in terminal hole 30.In addition, the contact site 40 of conducting terminal 4 have one protrude out backward and with the not coplanar bow-backed portion 44 of holding parts 43, bow-backed portion 44 supports on conductive layer 31 to be in contact with it.
On circuit board 3, cover an insulation board 5, which is provided with the some and corresponding through hole 50 of terminal hole 30, supply the contact site 41 of conducting terminal 4 to pass through.Chip module 2 is placed on insulation board 5, and the electric conductor 20 of its bottom contacts with the contact site 41 of conducting terminal 4.Insulation board 5 can prevent that the electric conductor 20 of chip module 2 is damaged to circuit board 3.
The below of circuit board 3 is separately provided with a baffle plate 6, and it covers the terminal hole 30 of circuit board 3 in bottom.The support portion 42 of conducting terminal 4 is set as curved hook arrangement and supports on baffle plate 6.The free terminal of support portion 42 is butted on the conductive layer 31 of terminal hole 30 inwalls.Because conducting terminal 3 has Multi-contact to conductive layer 31, thereby can shorten conductive path, reduce inductance.
For making chip module 2 can more stably be fixed on circuit board 3 tops, the present invention is separately provided with fixture (do not indicate), it comprise be crimped on chip module 2 tops pressing plate 7, be positioned at the backboard 8 of baffle plate 6 belows and by pressing plate 7 and the backboard 8 fixing screw 9 that locks together.The end of screw 9 is in conjunction with a nut 10.Fixture in the present invention also can adopt other form, as the both sides of chip module or four angles directly form reference column, directly inserts in location hole corresponding on circuit board to fix with circuit board.Such mode also forms fixture of the present invention.
Fig. 4 and Fig. 5 are the circuit board 3 ' of second embodiment of the invention, and lower surface is coated with metal level 33 thereon.In conducting terminal, in the corresponding terminal hole 30a of earth terminal, conductive layer 31a is connected with metal level 33.And the top of the corresponding terminal hole 30b of signal terminal is provided with the insulation colloid 34 being attached on circuit board 3 ', and because of insulation colloid 34 make the conductive layer 31b and metal level 33 phase electrical isolation on its inwall.Because the surface of circuit board 3 ' has the metal level 33 with earth terminal phase electrical communication, can form earth terminal parallel effect, thereby can reduce grounded inductor.
Fig. 6 and Fig. 7 are the circuit board 3 of third embodiment of the invention ", it sets up some shield openings 35 that are distributed between terminal hole on the basis of above the second embodiment.The diameter of shield opening 35 is less than the diameter of terminal hole, circuit board 3 " metal level 33 on surface " be together overlying on shield opening 35 inwalls with earth terminal electrical communication, thereby form the shield effectiveness between signal terminal, prevent signal cross-talk.
By above detailed description of the invention, can be drawn, because arrangements of electric connection of the present invention has been cancelled the insulating body design that is used for loading conducting terminal in traditional design, but conducting terminal is directly located in circuit board, therefore can reduce the height of whole device, provide cost savings simultaneously.
