Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a durable connection terminal that is resistant to the twisting force of the insertion connection terminal.

[0002]

[Prior art]

 Conventionally, a receiving / connecting terminal accommodated in a connector box, a fuse box, or the like is formed by bending a single conductive metal plate, and a movable contact piece is formed inside by bending the same conductive metal plate. Such a movable contact piece may be subjected to a prying force when a plug-in connecting terminal such as a fuse terminal or a tab terminal is inserted, which may be repeated to cause fatigue breakage, or may be forced to permanently deform. Therefore, the movable contact piece is required to have a high elastic force.

[0003]

[Problems to be solved by the device]

 However, this movable contact piece has a problem that when it is made of a highly elastic material, its conductivity becomes low, and conversely, when it is made of a highly conductive material, its elastic force becomes low.

An object of the present invention is to solve the above-mentioned problems and to provide a connection terminal that can maintain a high elastic force even if it is formed of a highly conductive material.

[0005]

[Means for Solving the Problems]

 The connection terminal according to the present invention for achieving the above-mentioned object includes a connecting portion formed by punching a single conductive metal plate and bending it into a box-like shape, and cutting both side plates of the connecting portion into the connecting portion. And an elastic contact piece formed by bending a separate conductive metal plate into a substantially bag-shaped cross section is mounted between the movable support pieces. The feature is that it is placed toward the entrance side of the connection part.

[0006]

In the connection terminal having the above-described configuration, the mating insertion connection terminal is clamped by the elastic contact piece having a substantially bag-shaped cross section supported by the movable support piece in the connection portion.

【Example】

 The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a plan view of a part of the embodiment in section, FIG. 2 is a side view thereof, and FIG. 3 is a front view thereof. The connection terminal 1 is formed by punching and bending a conductive metal plate, and is inserted and connected on the mating side. A connection part 2 for receiving a terminal, a stabilizer 3 for ensuring stability with a housing (not shown), a core wire crimping part 4 for crimping a core wire of an electric wire, a cover pressing part 5 for crimping a covering of an electric wire, and other connection terminals At the same time, a terminal connecting portion 6 is provided that is integrally connected and cut appropriately.

The connecting portion 2 is formed in a substantially box shape, and the stabilizer 3, the core wire crimping portion 4, the covering crimping portion 5, and the terminal connecting portion 6 are formed in a substantially U-shaped cross section. The connecting portion 2 includes a bottom plate 7, side plates 8 and 9 connected to both sides of the bottom plate 7, top plates 10a and 10b in which the side plates 8 and 9 are inwardly bent to face each other, and a top plate 10a, The rear portion of 10b is surrounded by projecting pieces 11a and 11b bent inward.

Further, a part of the side plates 8 and 9 is punched out in an inverted U-shape as shown in the drawing, leaving a rear base portion, and each is bent inward to form movable support pieces 12 and 13. . As shown in FIG. 4, an elastic contact piece 14 having a substantially bag-shaped cross section with a closed tip is fitted between the movable support pieces 12 and 13 and the projecting pieces 11a and 11b. . The elastic contact piece 14 is formed, for example, by bending a conductive metal plate of substantially the same material as the connection terminal 1, and is in close contact with the base portion 14a, the bent portions 14b, 14b, and the inclined portions 14c, 14c approaching each other. It has the contact portions 14d, 14d and the free ends 14e, 14e that expand outwardly with respect to each other, and are inserted into the connection portion 2 when the connection terminal 1 is molded. Here, the base portion 14a is in contact with the projecting pieces 11a and 11b, and the bent portions 14b and 14b are in close contact with the inner wall of the connecting portion 2. The two inclined portions 14c are arranged along the movable support pieces 12 and 13.

When a plug-in connecting terminal (not shown) is inserted into the connecting portion 2 of the connecting terminal 1, the plug-in connecting terminal is inserted between the contact portions 14d, 14d of the elastic contact piece 14, and the contact portions 14d, 14d and the inclined portion. The portions 14c and 14c bend outward and at the same time elastically contact the movable support pieces 12 and 13. Therefore, the insertion connection terminal is pinched by the contact portions 14d, 14d of the elastic contact piece 14 and also by the biasing force of the movable support pieces 12, 13.

[0011]

[Effect of device]

 As described above, in the connection terminal according to the present invention, since the separate elastic contact pieces having a substantially bag-shaped cross section whose tips are in close contact with each other are inserted between the movable support pieces, the connection terminals are inserted into the elastic contact pieces. When the connecting terminal is inserted, the elastic force of the elastic contact piece is reinforced by the elastic force of the movable supporting piece, and a high contact pressure can be obtained even with a connecting terminal made of a highly conductive material having a low elastic force.
