See also shown in Figure 4ly, described second terminal 3 is similar substantially to the first terminal 2 structures, extends straight down but the main part 30 of second terminal 3 is lateral margins from crossbeam 31 leading sections, and promptly main part 3 is not provided with the end 210 as the first terminal 2.

Main part

30 and 301 of the 3rd interference parts are provided with transition part 300.

See also Fig. 2 to shown in Figure 4, during assembling, arrange first, second terminal the 2, the 3rd of conducting terminal down, replace arrangement and be assembled into insulating body 1, and be fixed in first accepting groove 14 with first holding hole 141,142 interference of second holding hole respectively by first interference part 211,311, second interference part 201,301 from front end face 10.22,32 front end faces 10 that extend insulating body 1 respectively of weld part, the contact site 212,312 of elastic arm 202,302 ends protrudes in the slot 13 of insulating body 1 to electrically connect with electronic cards (not shown), all the first terminals 2 are in alignment with each other, and all second terminals 3 also are in alignment with each other.Adjacent first accepting groove 14 structure when moulding is identical, and the main part 20 of the first terminal 2 is resisted against the internal face 143 of first accepting groove, and this internal face is towards front end face 10; The transition part 300 of second terminal 3 is resisted against the internal face 143 of first accepting groove 14, the other parts of main part 30 then keep at a certain distance away with internal face 143 and not against.The main part 30 of second terminal 3 is with respect to the main part 20 more close front end faces 10 of the first terminal 2, and promptly the

main part

20,30 of terminals of adjacent is not oppositely arranged, but dislocation before and after forming.See that from the side the

main part

20,30 of the first terminal 2 and second terminal 3 does not have overlapping, can certainly overlap.

See also shown in Figure 5, described the 3rd terminal 8 comprise a main part, autonomous body upwards and forward bending and the part elastic arm and the autonomous body end lateral buckling to insulating body 1 outside that protrude into slot 13 extend and the welding foot 82 of formation.Described main part comprise vertical setting first main part 80, be positioned at first main part side's after 80s second main part 81 and connect first main part 80 and the inclination connecting portion 810 of second main part 81, elastic arm is to extend to form from this second main part 81, and the front portion of described main part is provided with the 3rd interference part 811 with the 3rd holding hole 151 fixings.First, second

main part

80,81 is not on same vertical curve, and promptly first main part 80 is positioned at the place ahead of second main part 81.

See also shown in Figure 6, described the 4th terminal 9 and the 3rd terminal 8 structural similarities, difference is that the main part 90 of the 4th terminal 9 extends straight down, and is provided with as the connecting portion 810 of the 3rd terminal 8, and

main part

90 and 901 of the 4th interference parts are provided with transition part 900.

See also Fig. 2 to shown in Figure 6, during assembling, describedly go up row's conducting terminal the 3rd terminal 8, the 4th terminal 9 is alternately arranged and be assembled into insulating body 1 from rear end face 17, and mat the 3rd interference part 811,911, the 4th interference part 801,901 respectively with the 3rd holding hole 151, the 4th holding hole 152 is interfered and be fixed in second accepting groove 15.Weld

part

82,92 bending outside insulating body 1 respectively, the contact site 812,912 of elastic arm end protrude in the slot 13 of insulating body 1 to electrically connect with electronic cards (not shown).First main part 80 of the 3rd terminal 8 is resisted against the internal face 153 of second accepting groove 15, and this internal face 153 then keeps at a certain distance away with internal face 153 towards rear end face 17, the second main parts 81; The transition part 900 of the 4th terminal 9 is resisted against internal face 153, and main part 90 then keeps at a certain distance away with internal face 153.At this moment, on arrange in the terminal first main part 80 of the 3rd terminal 8 and be positioned at main part 90 the place aheads of adjacent the 4th terminal 9 and be not and be oppositely arranged, promptly the main part 90 of the main part of the 3rd terminal 8 and the 4th terminal 9 shifts to install before and after forming.

In the present embodiment, the body width of first,

second terminal

2,3 is identical, and the body width of the 3rd, the 4th terminal 8,9 is identical, by the change to terminal structure (being the main part position), realizes the front and back dislocation of terminal, reduce between terminals of adjacent over against area.Being provided with of the transition part 300,900 of second terminal 3 and the 4th terminal 9 can strengthen the stability of terminal in first, second accepting

groove

14,15.

The utility model electric connector is mainly by alternately arranging the two kinds of terminals of at least one row in upper and lower two row's terminals, make

main part

20,30 to the small part of terminals of adjacent not face setting, promptly form and shift to install to small part, so, the electric property of electric connector when having improved high frequency, and the upper and lower accepting groove of respectively arranging terminal is the same, does not also increase the manufacture difficulty of electric connector simultaneously.

Certainly, the utility model also has other execution modes.As, the terminal of multiple structure is set in every row's terminal, do not face as long as guarantee main part to the small part of adjacent both ends, dislocation gets final product before and after promptly forming to small part.Give unnecessary details no longer one by one herein.
