Field of the Invention The present invention relates to a method for manufacturing a receiving connection terminal for receiving a mating insertion terminal. 2. Description of the Related Art Conventionally, as a conventional example of this type of connection terminal, for example, a connection terminal disclosed in Japanese Patent Application Laid-Open No. Sho 61-165970 is manufactured by punching a conductive metal plate and bending the punched conductive metal plate. ing. That is, as shown in FIG. 5, the connection terminal 1 is composed of a terminal connection part 2 and an electric wire crimping part 3, and the terminal connection part 2 is composed of a bottom plate 4 and side plates 5, 6 connected to both sides of the bottom plate 4. And these side plates 5, 6
The movable contact piece 9 is folded back into the terminal connection part 2 from the front of the bottom plate 4. [0003] As a second conventional example, a connection terminal that eliminates waste of material removal in the above-described conventional example is disclosed in Japanese Patent Application Laid-Open No. 3-931.
No. 75 discloses this. As shown in FIG. 6, of the terminal connection portion 12 of the connection terminal 11 and the wire crimping portion 13, the terminal connection portion 12 includes a bottom plate 14, side plates 15 and 16, and a top plate 1.
7 and a top plate 17 inside the terminal connection portion 12.
The movable contact piece 18 connected by the connecting piece from the side of
A pressing piece 19 is folded back inside the top plate 17 and a front end of the folded movable contact piece 18 is folded back. However, in the above-mentioned first conventional example, since the movable contact piece 9 is folded back from the front of the bottom plate 4, a wide plate material must be used. Moreover, there is a problem that the material on both sides of the movable contact piece 9 is wasted. In the second conventional example, since the movable contact piece 18 is folded back to the top plate 17, the movable contact piece 18 needs to be attached to the bottom plate 14 side. There is a problem that can not be. An object of the present invention is to solve the above-mentioned problems and to provide a method of manufacturing a connection terminal for mounting a movable contact piece on a bottom plate side. In order to achieve the above-mentioned object, a method of manufacturing a connection terminal according to the present invention comprises a bottom plate, both side plates connected to both sides of the bottom plate, and at least one of these side plates. A top plate connected to one side, a movable contact piece disposed parallel to a side of the side plate or the top plate, connected to a tip end of the bottom plate by a bridging piece, and provided with a projection at a front end; Forming a pressing piece for fixing the projection of the movable contact piece by bending the conductive piece by punching one conductive metal plate, and folding the bridging piece and forming the movable contact piece in a mountain shape. Step of bending on the bottom plate with its top facing the top plate side, and raising the both side plates,
Folding back the holding piece and locking the protrusion of the movable contact piece with a locking portion provided on the holding piece to fix the front end of the movable contact piece to the bottom plate; and The method comprises a step of bending and a step of cutting the bridging piece after fixing the movable contact piece. According to the method of manufacturing the connection terminal having the above-described structure, the movable contact piece having the contact portion facing the top plate is locked by the locking portion provided on the holding plate using the bridging piece. Then, the mating connection terminal is received between the top plate and the movable contact piece. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a longitudinal sectional view, FIG. 2 is an enlarged sectional view of a connecting portion, and FIG. 3 is a front view. The connection terminal 21 is formed by bending a single conductive metal plate, and has a front end provided with a terminal connection part 22 into which a mating connection terminal is inserted.
At the rear end, an electric wire crimping portion 23 to which the core of the electric wire and the coating are crimped is formed. The terminal connection part 22 is a bottom plate 24
Corners surrounded by side plates 25 and 26 which are connected to the both sides of the bottom plate 24 and which are raised, and top plates 27 and 28 which are connected to the side plates 25 and 26 and are bent horizontally. It is cylindrical. Here, the top plate 28 is joined to a throttle-down portion 27 a formed on the top plate 27. A movable contact piece 29 is provided in the terminal connecting portion 22 so as to overlap the bottom plate 24.
9 is bent in a chevron shape and has two protrusions 29a and 29b at the front end.
Is provided. At the front end of the movable contact piece 29, a pressing piece 30 extending forward of the bottom plate 24 is folded. The holding piece 30 has a T-shape composed of a base 30a and a wing 30b, and is folded over the front end of the movable contact piece 29 so that the projections 29a and 29b form the wing 30.
b. A cutout hole 24a and a cut-out portion 24b are formed behind the bottom plate 24, and a cut-down portion 27 is formed behind the top plate 27.
b is formed. The wire crimping portion 23 has a wire crimping piece 3
2 and the coating crimping piece 33 are formed in a U-shape, respectively. FIG. 4 is a plan view of the metal plate before the connection terminals 21 are formed. The movable contact piece 29 is punched from the front end of the bottom plate 24 to the side of the top plate 28 via the bridging piece 31. I have. Such a metal plate is stacked on the bottom plate 24 by first folding the movable contact piece 29 at the contact portion 29c in an inverted mountain shape and then folding the bridging piece 31 at the folded portion 31a. The pressing piece 30 is folded back at the front end of the folded movable contact piece 29, and the protrusion 29 of the movable contact piece 29 is formed.
a, 29b are locked by the wings 30b of the holding piece 30. After the side plates 27, 28 are raised, one of the side plates 27 is bent horizontally, and then the other side plate 28 is bent into the narrowed portion 27a of the side plate 27. , A rectangular tube-shaped terminal connecting portion 22 is formed.
The folded bridging pieces 31 are cut and removed at the cut portions 31b and 31c. In the thus formed connection terminal 21, when a connection terminal (not shown) is inserted between the top plate 27 and the movable contact piece 29, the contact portion 29 c of the movable contact piece 29 is inserted. Is pressed downward, the movable contact piece 29 bends, and its free end 29 d slides on the bottom plate 24. At this time, the movable contact piece 29 is pushed in the insertion direction, but the projections 29 a and 29 b of the movable contact piece 29 are securely locked in the insertion direction by the wings 30 b of the holding piece 30. Various types of connection terminals having the movable contact piece 29 fixed to the bottom plate 24 are also conceivable, and the movable contact piece is not necessarily formed as shown in FIG. If the piece 29 is formed from a separate metal plate capable of withstanding a high load, it can be used for heavy duty. As described above, in the method of manufacturing a connection terminal according to the present invention, the movable contact piece with the contact portion facing the top plate is locked to the bottom plate. It can handle the required connection terminal on the other side. Further, at the time of punching, the movable contact piece disposed on the side of the side plate or the top plate is folded back by the bridging piece and further locked by the pressing piece, so that waste of material removal can be eliminated.
