The terminal 112 of the first connector 110 is only formed by pressing a metal plate. The terminal 112 has a fixed portion 113 that is press-fitted and fixed to the housing 111, and extends from the fixed portion 113 so that the cut edge surface contacts the roll surface of the counterpart terminal 122. The contact portion 114 and the circuit board connecting portion 115 extend from the fixing portion 113 and contact the circuit board (not shown). The plurality of terminals 112 are arranged on the casing 111 so that the roll surfaces of the adjacent terminals 112 are opposed to each other. On the other hand, the terminal 1 2 2 of the second connector 120 is formed by pressing a metal plate, and the bending force σ is formed. The terminal has a fixing portion 123 that is press-fitted and fixed to the housing 121, and a fixing portion 123 from then on. A contact portion 124 extending from the roll surface to contact the cut edge surface of the counterpart terminal 112, and a circuit board contact portion 125 extending from the fixing portion 123 and connecting to a circuit board (not shown). As shown in FIG. 9 which can best represent the contact portion 124, the contact portion 124 is bent before: = 23 and the paper surface is orthogonal to each other. Terminal 122 arranges the reel surface of the adjacent solid part 1 2 3 in contact with each other and arranges it in the case. [Problem to be solved by the invention] Here, the reel surface contact type of twisted plate is not applied to the fixing part. The electrical contact area is large and due to the reliability of the contact. Turning to the extended contact makes the metal connector assembly smoother, so the electrical connection is improved.

Due to the narrow width of the cutting edge surface, when the terminals are multi-polarized, the contact distance between the contacts is uneven. In the future, it is likely to form an inaccessible problem. In addition, the electrical connector combination of the contact type of the metal plate roll surface and the cut edge surface shown in FIG. 8 uses the wide contact portion 124 roll surface as the contact surface, so when the terminals H2 and 122 are multi-polarized At this time, even if the arrangement distances of the terminals 112 and 122 are uneven, the terminals 112 and 122 still maintain electrical contact with each other within a certain range. In addition, the terminal 112 of the first connection 110 formed only by the stamping process has a width that compensates for the uneven position of the contact portion 124 of the terminal 121 of the second connector 120 whose contact surface is a roll because of its elasticity. Preferably, this has the advantage of reducing the arrangement distance of the terminal i 21. However, in order to make the roll surface of the contact portion 124 contact the cutting edge surface of the contact portion 114, if the smoothness of the cutting edge surface is not good, the reliability of the electrical connection between the contact portions 丨 2 and i 0 will be reduced. . Therefore, in order to solve the above-mentioned problems, the present invention provides an electrical connector combination in which a high degree of reliability in electrical contact between terminals and a high density of terminals are arranged.

When pressure is applied to both edges of the fixing portion 81, a plurality of barbs 81 are formed to protrude into the case body 71. In addition, on both surfaces of the fixing portion 8, protruding portions 81b and 81c are formed to prevent falling in the longitudinal direction after being pressed, and these portions are formed when a metal plate is punched. In addition, the pair of contact portions 82 are arranged in the through-hole 75 so as to face each other, and constitute an elastic contact portion that makes elastic contact with the counterpart terminal 52. Further, the circuit board connection portion 83 is provided with a solder connection portion 8 3 a which is welded to the conductive electrode on the circuit board ζ. Each second terminal 80 is formed by stamping a metal plate such as yellow steel and twisting, while the fixing portion 81 and the circuit board connection portion 83 are formed by stamping a metal plate only, and the contact portion 82 is stamped by a metal plate.

The contact portion 82 is formed with a contact protrusion 82d which is bent outward in the front-rear direction and protrudes, and a roll surface outside the contact protrusion 82d constitutes a contact surface with the first terminal 50. In addition, the plate width of the roll surface 82b of the contact portion 82 is larger than the plate thickness of the cut edge surface 82c.

組立第二端子60時，首先將第二端子8〇之固定部81自 下方壓入第二殼體70之固定部壓入固定用孔76 ,此壓入作 業皆是關於第二端子80。在此狀態下，第二端子是使鄰 接之第一端子80之固定部81的兩面相對向接觸般沿長度方 向配列。因此，第二端子80是配列於接觸部82捲筒面82b 之板寬度方向。接著，將焊接柱79壓入固定於焊接柱壓入 固定用凹部78中。從而，將第二接觸部8〇之焊接接續部 83a焊接於電路板B上之導電性電極上之同時，將焊接柱 焊接接續於電路板β上。依此，第二連接器β〇可安裝於電 路板上。 接著，參照圖七，說明第一連接器10與第二連接器6〇 之嵌合。圖七為關於本發明電氣連接器組合體之斷面圖。 如圖七所示，將第一連接器安裝於電路板人之狀態， 嵌合第二連接器60之嵌合凹部73與第一連接器1〇之乘合部 43後，就完成電氣連接器組合體1。在此，第一接觸部5〇 之接觸部52於底部附近52a扭轉’而金屬板捲筒面Hb面向 前後方向（圖七之左右方向），接觸部52之前後方向内側 捲筒面構成與第二端子80之接觸面。另一方面，第二端子 80之接觸部82於底部附近82a扭轉，金屬板之捲筒^以面When assembling the second terminal 60, first, the fixing portion 81 of the second terminal 80 is pressed into the fixing hole 76 of the second case 70 from below. This pressing operation is all about the second terminal 80. In this state, the second terminals are arranged along the longitudinal direction such that both surfaces of the adjacent fixing portions 81 of the adjacent first terminals 80 are opposed to each other. Therefore, the second terminal 80 is arranged in the plate width direction of the roll surface 82 b of the contact portion 82. Next, the welding column 79 is press-fitted to the welding column press-fitting recess 78. Therefore, while the solder connection portion 83a of the second contact portion 80 is soldered to the conductive electrode on the circuit board B, the soldering post is soldered to the circuit board β. Accordingly, the second connector β0 can be mounted on the circuit board. Next, the fitting of the first connector 10 and the second connector 60 will be described with reference to FIG.
