In the process of forming the recess, the adjustment is difficult, and if it is too deep, the contact may be cracked after the concave portion is formed. Further, since the shape is formed into the concave portion twice, the concave portion is concentrated and collapsed to cause cracking. Thus, depending on the structure of the touch. In the middle of the construction, the first contact area ruler and the X-shaped cross are constructed by the structure bulletin 5, and the depth of the groove is the contact that is easily used for stress when the contact portion of the trap member is bent into the recess. Unlike the bending of the contact portion of the contact member, the easiness of occurrence of cracks is also different, and thus the problem of poor productivity of the contact member is caused. The contact structure of the contact for an electrical connector of the present invention has been proposed to solve such a problem. (Means for Solving the Problem) Here, the contact structure of the contact for an electrical connector of the present invention is fixed to the female contact of the receptacle connector and the plug connector fitted to the receptacle connector A contact portion of one of the male contacts corresponding to the position at which the female contact is fixed and disposed is integrally supported from the contact base in the longitudinal direction of the contact, and toward the contact The plate thickness direction is curved and the contact portion is convexly formed toward the contact side, and a cross-shaped, X-shaped or v-shaped intersecting first concave portion and a second concave portion are formed on the contact side surface of the contact portion, wherein the cross The first recess and the second recess are formed at different depths. [Effects of the Invention] According to the contact structure of the contact for an electrical connector of the present invention, the depths of the first concave portion and the second concave portion which are provided at the intersection of the contact portions are different, thereby suppressing the occurrence of cracks and improving productivity. As a result, the types of contact materials that can be used are also expanded, and the versatility is also improved. Further, the contact reliability in the contact portion is improved by the difference in depth between the intersecting first concave portion and the second concave portion. Further, the degree of freedom in the design of the contact member is increased and the contact resistance at the time of insertion and removal is reduced. 8-6-201110472 [Embodiment] The contact structure of the contact 1 for an electrical connector according to the present invention is as shown in Figs. 1A to 1D. a plurality of female contacts that are fixed and provided in a socket connector (not shown), and a plug connector (not shown) that is fitted to the socket connector, and a position corresponding to the position of the female contact is fixed A contact portion of the contact 1 of one of the contacts. Further, the contact portion is integrally supported from the contact base 2 (welded to the printed circuit board or the like) in the longitudinal direction of the contact member 1, and is bent toward the thickness direction of the contact member 1 toward the contact side. The convex portion is formed, and the first concave portion 4 and the second concave portion 5 which are X-shaped intersecting are formed on the contact side surface 3 of the contact portion. The first and second recesses intersecting each other are formed by different depths. [Embodiment 1] The contact 1 is, for example, a female contact that is fixed and provided in a housing portion of a contact of a receptacle connector. Further, the surface of the contact portion of the male contact on the other side in contact with it is flat. The tip end portion of the contact member 1 is formed by bending inwardly to form a contact portion that is convex outward, and a first recess portion 4 and a second recess portion 5 that are X-shaped intersecting are formed on the contact side surface of the contact portion. The first and second recesses 4, 5 are processed by a mold, but the depth is as shown in FIG. 2C, the depth dl of the first recess 4 is deep, and the depth d2 of the second recess 5 is The depth dl of a recess 4 is shallower. In the present embodiment of 201110472, the depth dl of the first recess 4 is about 9/zm, and the depth d2 of the second recess 5 is about 3; um. In this case, the deeper first recess 4 is first machined, and thereafter the second recess 5 is machined. In the contact member 1 of the first embodiment, the first recess depth dl=about 9/zm and the second recess depth d2=about 1.5; the first, first electrical contact performance is compared with other contacts. And when the second recess is a contact of the same depth of the contact dl=d2=about 3 ym and the recess is not formed, the better one is indicated by the > mark: the first recess depth dl = about 9 μ m, the second recess depth d2 = about 3 〆 m > the first recess depth dl = about 9 / zm, the second recess depth d2 = about 1.5 / z The first and second recesses are the same depth of contact d 1 = d 2 = about 3 m > contacts in which the recess is not formed. [Embodiment 2] As shown in Figs. 3A to 3C and Figs. 4A to 4C, the contact members 1a are provided with cross-shaped first and second recesses 6, 7. The depth of the first recessed portion 6 is deep, and the depth of the second recessed portion 7 is shallower than the depth of the first recessed portion 6. The other conditions in this embodiment are the same as in the first embodiment. Further, the first recessed portion 6 having a deeper depth is first processed, and thereafter, the second recessed portion 7 is processed. [Embodiment 3] In the first embodiment and the second embodiment, 'in the first and second recesses 4, 5, the first and second recesses 6, 7', when the cross section of the contact side surface 3 is seen, As shown in Fig. 5A to 5C, the comparison: the side angle of the side wall of the recessed portion -8" 201110472, the rising angle 0 of the surface 8 is formed by expanding from the bottom surface of the concave portion at an angle of 90°, and gradually approaching 9 (Γ The contact performance of the formed condition. Here, the contact of the solvent film on the other side of the contact is contacted by a predetermined pressing force. The film thickness of the solvent, wherein a μ m 〇 the above angle 0 is closer to 90°, the corner portion In other words, it is found that a sufficient contact reliability can be obtained without making the corner portion R extreme as the diameter r. Thereby, the degree of contact can be expanded. Further, by not requiring the corner portion The tip end of R is fine, and the contact resistance at the time of insertion and removal can also be reduced. In the first and second embodiments, the first and second fifth, first and second recesses 6, 7 are shown as a cross type, X type. The intersection is not limited thereto, and may be a recessed portion that intersects with a V-shape or the like. Thus, the conventional one cannot be the same. In the shape of the present invention, the contact material of the contact portion of the present invention can be increased in shape. [Industrial Applicability] The contact structure of the contact member of the present invention can be widely applied to the electric contact member.
