For example, those shown in FIGS. 4 and 5 are known (see Japanese Utility Model Registration No. 2500882). The electric contact 100 shown in FIG. 4 has a receptacle portion 101 in front of a substrate 108 and an electric wire connection portion 102 including a conductor crimping piece 103 and an insulator crimping piece 104 in the rear. The receptacle portion 101 includes a substrate 108 and a substrate 1
08, a pair of upright side walls 105a that are raised from both sides.
105b, and an upper ceiling wall 106a and a lower ceiling wall 106b which are bent inwardly from each other from the upright side walls 105a, 105b above the substrate 1 and overlapped vertically, and the upper ceiling wall 106a and the lower ceiling wall 106b A mating tab 115 can be received between the substrate and the substrate 108. Further, the elastic tongue 107 is folded back from the tip of the substrate 108 into the receptacle portion 101, and the contact plate 109 facing the elastic tongue 107 is formed by stamping on the lower ceiling wall 106b. 4B, the end surface 114b of the lower ceiling wall 106b at the tab entrance 111 of the receptacle 101 is located inside the end surface 114a of the upper ceiling wall 106a by a dimension L. As shown in FIG. Thus, the electrical contact 100 avoids abutment of the tip of the mating tab 115 with the end surface 114b when inserting the mating tab 115, and facilitates insertion of the mating tab 115 into the receptacle portion 101. Reference numeral 110 in FIG. 4B indicates a housing into which the electrical contact 100 is inserted and held. On the other hand, the electric contacts 12 in FIG.
A reference numeral 0 indicates that the basic structure is the same as that of the electric contact 100 shown in FIG. 3, but the method for positioning the end surface 114b of the lower ceiling wall 106b inside the end surface 114a of the upper ceiling wall 106a is different. That is, in FIG.
A notch 114c extending from the upper ceiling wall 106b to the lower ceiling wall 106b is formed so that the end surface 114b of the lower ceiling wall 106b is positioned inside the end surface 114a of the upper ceiling wall 106a.

プタクル部分１１の内側へ入り込む。The mating tab 26 is inserted into the receptacle portion 11 of the electrical contact 1 from the tab entrance side (the left end side in FIG. 3), and is sandwiched between the contact plate 19 and the contact projection 18b of the elastic tongue piece 18. You. At the time of this insertion, FIG.
As shown in FIG. 7, even when the mating tab 26 is inserted obliquely from the bottom upward into the receptacle portion 11, the tab entrance-side distal end surface 22 of the lower ceiling wall 16b is turned into the tab entrance-side distal end surface of the cut-and-raised piece 17. Since the mating tab 26 is located on the inner side than the mating tab 21, the mating tab 26 can be smoothly inserted without abutting against the tab entrance side front end face 22 of the lower ceiling wall 16b. Here, the cut-and-raised piece 17 is an upright portion from which the lower ceiling wall 16b is connected to a free end on the upright side wall 15a side where the tab entrance side tip end portion 22 of the lower ceiling wall 16b of the receptacle portion 11 is connected to the upper ceiling wall 16a. As shown in FIG. 2, the cut-and-raised portion 17 is formed so as to be cut and raised over the side wall 15 b. Even when the lateral width We between the inner walls of the pair of upright side walls 15a and 15b is substantially equal and the lateral width of the mating tab 26 is substantially equal to the lateral width We between the inner walls of the pair of upstanding side walls, the mating tab 26 is not inserted at the time of insertion. Is difficult to abut against the tab entrance-side tip surface 22 of the lower ceiling wall 16b, and the insertion of the mating tab 26 can be easily performed. Also, the free end 17a of the cut and raised piece 17
Is placed on the upper end of the upright side wall 15a to which the upper ceiling wall 16a is connected, so that there is no gap between the lower surface of the free end 17a of the cut-up piece 17 and the upper end of the upright side wall 15a. When inserted into the receptacle part 11, there is no danger that the tip of the mating tab 26 enters the gap. Furthermore, since the inclined surface 24 is formed from the tab entrance side front end surface 21 of the upright piece 17 to the lower surface of the upright piece 17,
When the mating tab 26 is inserted, even if the tip of the mating tab 26 abuts on the inclined surface 24, the tip enters the inside of the receptacle portion 11 along the inclined surface 24, and the tab entrance of the lower ceiling wall 16b. From the side tip surface 22 to the lower ceiling wall 1
Since the inclined surface 25 is formed over the lower surface of 6b, the tip of the mating tab 26 that has entered the inside of the receptacle portion 11 along the inclined surface 24 further enters the inside of the receptacle portion 11 along the inclined surface 25.

ができる。According to the first aspect of the present invention, the front end of the lower ceiling wall at the tab entrance side of the receptacle portion extends from the upright side wall connecting the upper ceiling wall to the upright side wall connecting the lower ceiling wall. When the cut-and-raised piece is formed and the tab-entrance-side distal end surface of the cut-and-raised piece is substantially flush with the tab-entrance-side distal end surface of the upright side walls, the mating tab is inserted into the receptacle portion. Not only does the tip of this mating tab not abut against the tab entry side tip face of the lower ceiling wall, but also the tab entry side tip width of the lower ceiling wall located inside the tab entry side tip face of the cut-and-raised piece. And the width between the inner walls of the pair of upright side walls becomes substantially equal. Therefore, even when the width of the mating tab is substantially equal to the width between the inner walls of the pair of upright side walls, the mating tab is not inserted when the mating tab is inserted. It is difficult for the tip to abut the tip face on the tab entrance side of the lower ceiling wall Insertion of the mating tab can be easily performed.
In addition, since the free end of the cut-up piece is placed on the upper end of the upright side wall to which the upper ceiling wall is connected, there is no gap between the lower surface of the free end of the up-and-down piece and the upright side wall. There is no danger that the mating tab will enter the gap when the is inserted into the receptacle part. Therefore, there is no danger that the receptacle portion is deformed by the mating tab.
