Now please refer to Fig. 1, electric connector of the present utility model comprises a microscler insulation shell 10, and offers a central slot 20 on insulation shell 10 longitudinallies, and this central slot 20 is in order to take in the plate edge of a circuit substrate 100.In addition, has a row terminal storage tank respectively in insulation shell 10 vertical both sides, and each row terminal storage tank is with signal terminal storage tank 12 and earth terminal storage tank 14 interconnected modes and form, and form man-to-man corresponding relation with another row terminal storage tank.By can clearly be seen that on the figure, the signal terminal storage tank 12 of electric connector of the present utility model and earth terminal storage tank 14 are slightly different dimensionally, this be because the undersized of signal terminal of the present utility model due to the size of earth terminal, this will do more detailed description hereinafter.
Now, wherein show the three-dimensional view of signal terminal 30 of the present utility model and earth terminal 40 respectively please in the lump with reference to Fig. 2 A and Fig. 2 B.By on the figure as can be seen, each signal terminal 30 comprises a contact site 31, an elastic arm 32, a fixed part 33 and a pin portion 34.Wherein, this contact site 31 comprises that the upper limb of signal terminal 30 extends downward approximately and the position of circuit substrate 100 contacted contact point P, elastic arm 32 then roughly extends downward fixed part 33 by contact point P, this elastic arm 32 can provide strain when inserting central slot 20 at circuit substrate 100, thereby provides the enough positive forces of this contact site 31 to form firm with the plate edge of circuit substrate 100 and to contact reliably.Fixed part 33 usefulness are so that signal terminal 30 can firmly fix in signal terminal storage tank 12, and this is to form interference engagement by the fixing flange 331 that these fixed part 33 both sides upwards stretch out respectively with signal terminal storage tank 12 corresponding groove inwalls to reach.In addition, fix flange 331 lateral surfaces on the inwall direction of signal terminal storage tank 12 at each, also stretch out a hangnail 332 respectively, the effect of this hangnail 332 is in signal terminal 30 is installed in signal terminal storage tank 12 time, it can thrust the inwall of signal terminal storage tank 12, to avoid signal terminal 30 by coming off in the signal terminal storage tank 12.One pin portion 34 is extended downwards by fixed part 33 belows, goes up corresponding perforation in order to be inserted in main circuit board (on the figure show), and forms conducting with circuit on the main circuit board.
Each earth terminal 40 also comprises a contact site 41, an elastic arm 42, a fixed part 43 and a pin portion 44, and wherein this fixed part 43 further includes fixing flange 431 and hangnail 432.Because earth terminal 40 is identical with the structure of signal terminal 30 substantially, so the structure of each member and acting on is just given unnecessary details no longer separately.
Can clearly be seen that by Fig. 2 A and Fig. 2 B, the transverse width of the contact site 41 of earth terminal 40 is greater than the transverse width of the contact site 31 of signal terminal 30, and the fixed part of earth terminal 40 whole transverse width still is also greater than the transverse width of the fixed part 31 of signal terminal 30, thereby when being adjacent to signal terminal 30 between two earth terminals 40 when carrying out high-frequency signal transmission, because the expansion that lays respectively at two earth terminals 40 of signal terminal 30 front and back partly can provide a kind of effect of shielding, therefore just can reduce signal terminal 30 widely is subjected to noise jamming improperly when transmission signals.It should be noted that at this, spirit of the present utility model is to be to be designed to some privileged site of earth terminal more bigger than the position of signal terminal correspondence, as for this particular portion bit position and quantity, be that the occasion of shape, application on terminal and assembling difficulty or the like factor is decided.Though present embodiment is to illustrate with the design that the contact site 41 of earth terminal 40 and fixed part 43 are enlarged, yet the utility model is not only to be confined to this.In addition, as previously mentioned, earth terminal storage tank 14 of the present utility model is to be designed to be slightly larger than signal terminal storage tank 12, this also can provide to make assembler be easy to distinguish to be avoided the advantage of assembly defect except the size based on some privileged site of earth terminal 40 of the present utility model is slightly larger than the consideration of size of signal terminal 30.In addition, being dimensioned to of earth terminal storage tank 14 is more bigger, also can increase earth terminal in the flexibility that provides in the shield effectiveness design, avoid the shield effectiveness of earth terminal being lost to some extent because yielding to the size of earth terminal storage tank 14.
As previously mentioned, in the process of electric connector densification development, except the problem that will solve above-mentioned undue interference, still need and consider because number of terminals increases the problem that the insertion force when causing the central slot 20 of circuit substrate 100 insertions increases greatly.At this problem, the utility model also provides a solution that quite has an advantage at this.
Please in the lump with reference to Fig. 3, Fig. 4 and Fig. 5, wherein Fig. 3, Fig. 4 illustrate the cross section view that signal terminal of the present utility model, earth terminal are arranged in the terminal storage tank respectively, and Fig. 5 then is the generalized section that signal terminal and earth terminal are overlaped.At first please refer to accompanying drawing, if the vertical range between the contact point P of the contact site 31 of signal terminal 30 and elastic arm's 32 the bending point B is set at L, and the vertical range between the contact point P of the contact site 41 of earth terminal 40 and elastic arm's 32 the bending point B is set at L ', then can clearly be seen that by Fig. 3 and Fig. 4, distance L ' greater than distance L, in other words, when circuit substrate 100 inserts central slot 20, the earth terminal that plate edge two sides is first and electric connector is all forms clamping and contacts, when further inserting along with circuit substrate 100 then, it forms clamping with all signal terminals of electric connector again and contacts.By above design, because circuit substrate is to insert in the stressed mode of two-part, stressed the reducing in the time of therefore circuit substrate can being inserted, insertion force is excessive and cause the situation of inserting difficulty to produce when having avoided inserting in once stressed mode.
Yet the personage who has the knack of this technology should understand, and the design of above-mentioned high low level contact is to derive the problem (this is because due to the arm of force length L and L ' difference of distortion moment) that is subjected to different stress between the different ends.Offer a piece of advice it, if suffered stress difference between the terminal, then circuit substrate is through after the plug for several times, because the elastic fatigue degree difference between the terminal, the as easy as rolling off a log situation that causes some terminal to have loose contact produces.In order to solve this problem, the utility model advocates to reach the effect that makes different terminals have roughly the same forward chucking power for the plate edge of circuit substrate by the displacement between the different terminals of control at this.In detail, please referring again to Fig. 3 and Fig. 4, if the horizontal range between the contact point P of a pair of signal terminal is set at G, and the horizontal range between the contact point P of a pair of earth terminal is set at G ', then clearly, clearance G between a pair of signal terminal contact point P of the present utility model is greater than the clearance G between a pair of earth terminal contact point P ', thereby, when circuit substrate inserted the central slot of electric connector, signal terminal and earth terminal just can be roughly the same for the forward chucking power of plate edge.
Now please refer to Fig. 5, wherein earth terminal is to represent with solid line, signal terminal then is to represent with dotted line, from the figure as can be seen, the contact site 41 of earth terminal 40 of the present utility model and fixed part 43, under the state that assembling is finished, really can be (promptly with the position of signal terminal 30 correspondences, contact site 31 and fixed part 33) shielded, and reach the effect that reduces noise jamming.Moreover, because earth terminal of the present utility model is the design that adopts high low level to contact with signal terminal, and the design that the contact point gap between the paired different terminals is changed, make electric connector of the present utility model not only can reduce the insertion force of circuit substrate, and can also make signal terminal and earth terminal keep roughly the same forward chucking power.
