Consult shown in Figure 1ly, electric connector comprises insulating body 1 and is contained in some conducting terminals 2 in the insulating body 1.
Consult Fig. 2 and shown in Figure 7, insulating body 1 comprises up and down upper body 10 and the lower body 11 at heap base, be respectively equipped with upper terminal hole 100 and lower terminal hole 110 on the upper and lower body 10,11,100,110 corresponding connections of upper and lower terminal hole form the terminal hole that holds conducting terminal 2.Insulating body 1 roughly is square and is divided into some zones, comprises the zone line 13 that roughly is square, and in the second area 14 of four corners and the first area 15 between the adjacent second area 14, this first area 15 is positioned at four sides of zone line 13.Conducting terminal 2 is array way in insulating body 1 arranges, and comprises some rows and some row, and this conducting terminal 2 is different from the arrangement mode in the first area 15 at second area 14.
Continue to consult shown in Figure 2, conducting terminal 2 is assembled in up and down in the terminal hole 100,110.Each conducting terminal 2 has a backing arm of growing 20 and is upwards bent a resilient support arms 21 of lacking of extension by backing arm 20 bottoms.Backing arm 20 forms a weld part 22 with the bending place of support arm 21, and the free terminal of backing arm 20 tops is bent to form a contact site 23.Contact site 23 and weld part 22 pass respectively upper body 10 and lower body 11 and are respectively applied to and be electrically connected with a chip module (not shown) and a circuit board (not shown).
The conducting terminal 2 that is positioned at described first area 15 is arranged in the first order mode.With reference to Figure 1 and Figure 2, have vertical wall 101 and the abutment walls 102 relative with vertical wall 101 in each upper terminal hole 100.On same row's direction, the angle that these abutment walls 102 tilt from left to right successively increases gradually, and wherein first abutment walls 102 on the left side is zero degree with the angle of vertical direction, and rightmost abutment walls 102 is maximum with the angle of vertical direction.The structural similarity of the structure of lower body 11 and upper body 10, each lower terminal hole 110 has vertical wall 111 and abutment walls 112, this abutment walls 112 tilts in the same face with abutment walls 102 in the corresponding upper terminal hole 100, this vertical wall 111 staggers from left to right successively with vertical wall 101 in the corresponding upper terminal hole 100, is aligned to the distance that staggers from first of the left side and increases gradually.
Conducting terminal 2 is assembled in the upper and lower terminal hole 100,110, formed by aforesaid terminal hole structure conducting terminal 2 contact site 23 spacing d less than between the weld part 22 apart from D, therefore, little spacing, the high density of realization contact site 23 arranges to adapt to the chip module (not shown) of specific standard, is convenient to again electric connector assembling to circuit board (not shown) apart from D between the simultaneously larger weld part 22.Consult shown in the 3rd figure, this figure is the contact site 23 of the conducting terminal 2 arranged in the first order mode and the distribution schematic diagram of weld part 22, the position that wherein represents contact site 23 than great circle C, the position that represents weld part 22 than small circle S, as shown in the drawing, the layout area of the weld part 22 of conducting terminal 2 is greater than the layout area of contact site 23, the spacing of the weld part 22 of same row's adjacent conductive terminal 2 is greater than the spacing of contact site 23, the spacing of the weld part 22 of same row conducting terminal 2 is identical with the spacing of contact site 23, therefore this first order mode is namely take a row conducting terminal 2 or terminal hole as original benchmark, weld part 22 is along directions X (row place direction) expansion, be formed on the spacing of the adjacent weld part 22 of directions X greater than the spacing of adjacent contact section 23, and equate in the spacing of Y-direction (row place direction) weld part 22 and contact site 23, so this first order mode is also referred to as One-Dimensional Extended.
The conducting terminal 2 that is positioned at described second area 14 is arranged in the second order mode.The terminal hole 100 of second area 14,110 with the terminal hole 100 of conducting terminal 2 and first area 15,110 identical with conducting terminal 2 structures, difference is the arrangement mode of conducting terminal 2.With reference to Fig. 4 and shown in Figure 5, in the second order mode, with a conducting terminal 2 as the home position, first expand conducting terminal 2 in a row to directions X, then expand to Y-direction as the home position with this row's conducting terminal 2, realize that by conducting terminal 2 different deflection angles weld part 22 is to the two-way expansion of directions X and Y-direction.Emphasis is consulted shown in Figure 6, this figure is the contact site 23 of conducting terminal 2 in the second order mode and the position distribution schematic diagram of weld part 22, the layout area of the weld part 22 of conducting terminal 2 is greater than the layout area of contact site 23, wherein the spacing of the weld part 22 of same row's conducting terminal 2 is greater than the spacing of contact site 23, the spacing of the weld part 22 of same row conducting terminal 2 is also greater than the spacing of contact site 23, therefore this second order mode namely take near some conducting terminals 2 of zone line 13 as the home position, then weld part 22 is expanded to Y-direction to the directions X expansion first, the spacing that is formed on adjacent weld part 22 on directions X and the Y-direction is all greater than the spacing of adjacent contact section 23, so this second order mode is also referred to as two-dimensional expansion.
Consult Fig. 3 and shown in Figure 6, the distance that more peripheral conducting terminal 2 is extended is longer, no matter so One-Dimensional Extended or two-dimensional expansion, its abducent maximum length all can be subject to the restriction of electric connector manufacturing capacity, therefore the present invention combines One-Dimensional Extended and two-dimensional expansion mode, consult shown in Figure 7, conducting terminal 2 in the second area 14 is expanded with two-dimensional approach, conducting terminals 2 in the first area 15 are expanded in the one dimension mode, so not only can realize the contact site 23 of conducting terminal 2 and the different spacing between the weld part 22 but also can increase the quantity of arranging of conducting terminal 2.In order to increase the utilance of the central conducting strip of chip module (not shown), consult Fig. 8 and shown in Figure 9, four groups of conducting terminals 2 of arranging by the two-dimensional expansion mode can be set at the zone line 13 of insulating body 1 or two groups of conducting terminals 2 of arranging by the one dimension mode are set.The allocation ways of certain conducting terminal of the present invention 2 is not limited to this, and conducting terminal of the present invention 2 can also be embedded in the insulating body 1 by insert molding (insert-mold) mode.
Below only be the preferred embodiments of the invention, other any improvement conversion of doing on the present embodiment basis also should not break away from technical scheme of the present invention.
