のである.[Industrial Field of Application] The present invention relates to a female connecting terminal that is housed in a connector housing and is mated with a mating male connecting terminal to establish an electrical connection. C. Prior Art] In general, when a connecting terminal is housed in a connector housing, it is devised to improve the stability of its posture within the housing and to prevent so-called reverse insertion, in which the terminal is inserted upside down. ing. For example, Utsukai Showa 63-5
In Publication No. 4284, as shown in Fig. 6, a part of the top plate 2 and a part of the side plate 3 of the female connecting terminal l are overlapped to form a double structure, and this double structure part is lifted upward. This provides good adhesion between the side plate 3 and the wall surface 5 of the housing 4 to be accommodated, and furthermore prevents reverse insertion into the housing 4. [Problems to be Solved by the Invention] However, in this connection terminal 1, when excessive prying force is applied from the mating male connection terminal,
The top plate 2 will be lifted up, but if the top plate 2 is simply overlapped with the bent side plates 3, there is a good chance that this portion will come off and the top plate 2 will be deformed. An object of the present invention is to provide a connection terminal which can eliminate the above-mentioned drawbacks, maintain good adhesion to the housing, prevent reverse insertion, and sufficiently restrict deformation of the top plate. be. [Means for Solving the Problems] In order to achieve the above object, in the connection terminal according to the present invention, in the connection portion formed by bending a conductive metal plate into a substantially rectangular tube shape, the connection portion is Lift one side plate upward, lock the end of the top plate of the connection part in the notch made in the side plate, fold the upper part of the side plate downward into an inverted U shape, and then open the tip of the side plate. It is characterized in that it comes into contact with the top plate.

頼性が向上する.In the connection terminal having the above structure, one side plate extends upward and its tip is folded downward to hold down the top plate, so it has high mechanical strength against deformation of the top plate. The top plate is difficult to deform. [Example] The present invention will be explained in detail based on the example illustrated in FIGS. 1 to 5. FIG. 1 shows a perspective view, and the connecting terminal 1l has a connecting part l2 for receiving the mating insertion connecting terminal and a rear wire crimping part l.
All parts including 3 are formed by bending a single conductive metal plate, and the wire crimping part 13 has a core crimping part 14 and a covering crimping part 15 each shaped like a U, as in the conventional wire crimping part 13. It is well-formed. As shown in FIGS. 2 to 4, the connecting portion 12 has a bottom plate 17 having two elastic contact portions 16 that bulge inward, side plates 18 and 19 that are continuous on both left and right sides of the bottom plate 17, and one side plate 18.
The upper part is bent in the horizontal direction to form a substantially rectangular cylinder shape surrounded by a certain top plate 20, and a movable contact piece 2l connected to the side of the top plate 20 is folded back inside. This movable contact piece 2l has a base connected to the side plate l9 and a free end 21.
The contact point 2lb has an inverted chevron shape with the apex at the middle part between the top plate 20 and the free end 21a, and the free end 21a is fitted into the hole 20a of the top plate 20. 20b
The front end portion of the movable contact piece 21 is fixed, and the mating insertion connection terminal is inserted between the contact point 2lb of the movable contact piece 2l and the elastic contact portion 16 of the bottom plate 17. Further, the side plate 19 is raised higher than the top plate 20, and the tip of the fold 19a folded downward in an inverted U shape is placed against the top plate 20. The end of the top plate 20 is formed by a notch 19b provided in the side plate l9.
is engaged in. Note that 20c indicates a convex portion that bulges out from the top plate 20 into the connecting portion 12 in order to prevent excessive deformation of the movable contact piece 21. The mating flat blade-shaped insertion connection terminal (not shown) is inserted between the movable contact piece 2l and the elastic contact portion 16 of the bottom plate 17 as described above, but in that case, the elastic contact portion 16 is slightly At the same time, the free end 21a of the movable contact piece 2l
moves within the hole 20a, the movable contact piece 2l is largely elastically deformed, and the insertion connection terminal can be easily inserted. Furthermore, since the front end of the movable contact piece 21 is pressed down by the holding piece 20b of the top plate 20, it does not become an obstacle when inserting the mating connection terminal. When the insertion connection terminal is inserted, it is an elastic contact part! The elastic pressing force of both the contact piece 6 and the movable contact piece 2l strongly presses the insertion connection terminal, resulting in a good electrically conductive connection. Even if the insertion part of the male connection terminal is pushed into the connection part 11, excessive prying force is applied, and a force is applied to lift the top plate 20 through the movable contact piece 21, the top plate 20 is firmly held down by the U-shaped folds 19a of the side plate 19, so that no deformation occurs. Furthermore, since the side plate 19 is raised high, when the connecting terminal 11 shown by the dotted line is inserted into the housing 30 as shown in FIG. This results in good results, and furthermore, the fold 19a prevents reverse insertion into the housing 30. [Effects of the Invention] As explained above, the connection terminal according to the present invention is reliable because it has the functions of making good contact with the housing, preventing reverse insertion, and further preventing deformation of the top plate. improves.
