手段等によって確認することを可能にしている。An even more important point in the configuration of the female contact portion 20 is that the female contact portion 20 includes a configuration for preventing fine sliding wear. The configuration will be described below. As can be seen from FIGS. 3 and 4, the side wall 26 is
It has a first side wall 46a, a second side wall 46b, a third side wall 46c, and a fourth side wall 46d defined by the seam 43 and slots 45a, 45b, 45c extending in the height direction or the length direction. The first side wall 46a extends in a direction substantially orthogonal to the first bottom wall 21, and abuts on the second side wall 46b at the seam 43. The second side wall 46b extends from the top wall 24 in a substantially orthogonal direction. The seam 43 may be fixed by welding if necessary. The third side wall 46c extends from the top wall 24 in a direction substantially orthogonal to the top wall 24, and is mostly separated from the second side wall 46b by the slot 45a. Therefore, the third side wall 46c can be slightly displaced with respect to the second side wall 46b. Most of the fourth side wall 46d is separated from the third side wall 46c by a slot 45b communicating with the slot 45a. Therefore, the fourth side wall 46d
Is slightly displaceable in the three-dimensional directions (x, y, z directions) with respect to the second side wall 46b (and the first side wall 46a). The above-mentioned second bottom wall 22 is formed by bending the fourth side wall 46d inward at substantially right angles, and the contact piece 30 is formed on the second bottom wall 22 as described above. Therefore, the contact portion 32a of the contact piece 30
Contact portion 32 that comes into contact with a mating contact when the mating contact is received as described below between
a and the protruding portion 49 can be displaced in the three-dimensional direction, and there is no possibility that a contact failure due to fine sliding wear occurs in these portions. Further, the shoulder 48 facing forward of the first side wall 46a can restrain the displacement of the fourth side wall 46d described above. Further, the slots 45a and 45b make it possible to visually or optically confirm the contact with the counterpart contact when inspecting the contact state of the electrical contact 10.

による付勢力は受けない。Next, with reference to FIGS. 5 and 6, the operation of fitting the electrical contact 10 with the female mating contact 110 will be described. As shown in FIG. 5, before the female contact portion 20 receives the mating contact 110, the top side of the bent portion 31 is positioned near the top wall 24 but is placed so as not to contact the top wall 24, and the tongue piece portion 32 is placed. Extends toward the front so as to narrow the gap with the second bottom wall 22. At this time, it should be noted that the tip 33a of the extension portion 33 is located so as to overlap the protective wall 27. As shown, the contact piece 30 including the bent portion 31 and the tongue piece 32 is close to the projecting piece 40,
Is not energized by.

である。In the initial receiving state (not shown) of the mating contact 110, the mating contact 110 comes into contact with the extension portion 33, and the tongue piece 32 of the contact piece 30 is displaced to the top side (FIG. 4).
The bent portion 31 is slightly bent backward (see arrow A in FIG. 4) (see arrow B in FIG. 4). As the reception of the mating contact 110 proceeds, the tongue piece 32 of the contact piece 30 is bent outward. Therefore, the contact piece 30 deforms the projecting piece 40 and is supported thereby. It should be noted that the bending of the contact piece 30 extends over the entire bent portion 31 and the tongue piece 32 as described above.

端側に位置するので、有効嵌合長も比較的長くとること

くできるという利点がある。When the receiving of the mating contact 110 is completed as shown in FIG. 6, the mating contact 110 is sandwiched between the contact portion 32a of the contact piece 30 and the contact projection 49. The contact piece 30 and the projecting piece 40 provide sufficient contact pressure for electrical contact. At this time, the extension portion 33 is connected to the opening 29 of the top wall 24.
To enter. Due to the presence of the opening 29, a sufficient bending space for the contact piece 30 is ensured. In a series of fitting processes understood from the transition from the state of FIG. 5 to the state of FIG. 6, the elastic piece 30 is deformed toward the top side, particularly near the free end of the tongue piece 32 of the contact piece 30. When an excessive stress is applied, the edge 29a of the opening 29 abuts on the base of the extension 33 to suppress the bending, thereby preventing the contact piece 30 from being plastically deformed. Also, as can be seen in particular from FIG.
2a and the projecting portion 49 for contact are located relatively at the front end side of the female contact portion 20, so that the effective fitting length can be relatively long and the size of the mating female contact can be relatively short. There is.

用する。An elastic contact piece 230 is also formed inside the female contact portion 220. The main difference from the electric contact 10 according to the previous embodiment is the orientation of the elastic contact piece 230 and its arrangement. As shown, the elastic contact piece 2
30 does not extend from the bottom wall 224 side, but extends from the second top wall 222. The elastic contact piece 230 includes a curved extending portion 271 and a curved extending portion 27 that are curved from the second top wall 222.
A horizontal plate portion 272 extending substantially parallel to the first top wall 221 further rearward from 1, a bent portion 231 that extends from the rear side of the horizontal plate portion 272 toward a bottom wall 224 serving as an opposing wall, and a bent portion 231. The tongue piece 232 further extends forward, and the front end of the tongue piece 32 has an extension 233 that extends to bend toward the bottom wall 224. The horizontal plate portion 272 is located slightly away from the first top wall 221. The tongue piece 232 is a contact portion 23 that makes electrical contact with the mating contact when receiving the mating contact.
2a. The extension 233 also serves to guide the mating contact towards the contact portion 232a when receiving it. The curved extension portion 271 and the contact portion 232a are arranged to face each other, and the curved extension portion 271 can also be used as an electric contact portion. Further, end walls 282 and 283 that are bent inward from the top end and the bottom end are formed at the distal end of the female contact portion 220. The end walls 282 and 283 serve to protect the elastic contact piece 230 from the front and to guide it to an appropriate position with respect to the elastic contact piece 230 when receiving the mating contact.

Since the horizontal plate portion 272 of the elastic contact piece 230 is separated from the first top wall 221 as described above, a movement in the rotation direction about the curved extension portion 271 can occur (see arrow C in FIG. 8). ). As a result, the tongue piece 232 moves in a direction similar to the rotation in the direction of arrow D, abuts against the protruding piece 240, and is pressed by it. Accordingly, the mating contact can be inserted with a relatively small force, and a sufficient contact pressure is provided through the tongue piece 232.

The lance 241 is formed with a protrusion 242 protruding inward at substantially the center and extending in the length direction. The protrusion 242 terminates at the edge 243. As shown, the vicinity of the edge 243 is formed to extend substantially horizontally.
An upright wall 284 is formed on one side of the lance 241 at a substantially extended position of the side wall 226. In particular, it is understood from FIG. 8 that the upright wall 284 overlaps the lance 241 and protects the lance 241 from interference with external members such as a wire. Further, a projection 295 is formed at the edge of the opening 244 on the back surface of the lance 241. The protrusion 295 can interfere with the vicinity of the edge 243 of the lance 241, thereby preventing the lance 241 from entering the opening 244.
