[Problems to be solved by the device]

The present invention has been made in view of the above points, and an object thereof is to provide a pressure contact terminal advantageous in terms of manufacturing cost, management, and the like.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a terminal main body having an input / output unit on one side of a substrate unit and a small pressure contact piece for pressure contact of a small diameter electric wire provided on the other side of the substrate unit. It is characterized in that it is constituted by a large-diameter electric wire pressure contact member in which a large press-contact piece for pressing a large-diameter electric wire is erected on the substrate portion and a fitting hole for the small press-contact piece is provided.

[Action]

The small-diameter wire is connected to the small pressure contact piece of the terminal body. When connecting a large-diameter electric wire, the large-diameter electric wire pressure contact member is joined to the terminal body. This coupling is easily performed by fitting the small pressure contact piece into the fitting hole of the substrate portion of the large diameter wire pressure contact member.

〔Example〕

FIG. 1 is an exploded perspective view showing a press contact terminal according to the present invention.

In the figure, reference numeral 1 denotes a terminal body, which is formed by punching and bending a single conductive metal plate to integrally form a relay female terminal portion 2 as an input / output portion and a small-diameter wire pressure contact terminal 3. It is formed. That is, the relay female terminal portion 2 is provided on one side of the terminal board portion 4 so as to be orthogonal to each other, and the pair of small pressure contact pieces 5, 5 are provided on the other side of the board portion 4 so as to face each other with the same width as the relay female terminal portion 2. Let it stand. The relay female terminal portion 2 is formed by connecting an elastic contact piece 7 to the inner side of an outer wall 6 having a rectangular tubular shape, and the small press contact piece 5 is provided on the inlet side of the press contact slit 8 with a blade portion 9 for covering and tearing. Is formed.

Further, in the figure, reference numeral 10 denotes a large-diameter electric wire pressure contact member to be coupled to the same terminal body 1'as described above, and a pair of large pressure contact pieces 12, 12 are erected opposite to each other at both ends of the base plate portion 11, A pair of slit-shaped fitting holes 13, 13 for the small pressure contact pieces 5, 5 of the terminal body 1 are provided in the center of the portion 11 in parallel with the large pressure contact piece 12.

When the small-diameter electric wire 16 is pressure-welded, the terminal body 1
When connecting to the small pressure contact pieces 5 and 5, and when the large diameter electric wire 18 is pressure contacted, the small pressure contact pieces 5 and 5 are fitted into the fitting holes 13 of the large diameter electric wire pressure contact member 10 as shown in FIG. By press-fitting into the terminals 13 and 13, the terminal body 1 and the large-diameter electric wire pressure-contact member 10 are combined to form a pressure-contact terminal.
Forming 20.

Here, the connection between the terminal body 1 and the large-diameter wire pressure welding member 10 is
As shown in FIG. 3, the respective substrate portions 4 and 11 are brought into close contact with each other, and the fitting hole peripheral edge 14 is sandwiched by the base portion 15 of the small press contact piece 5, so that the operation is performed reliably.

Then, the large-diameter electric wire 18 is pressed against the large pressure contact piece 12, and the short bar 19 shown in FIG. 1 is inserted into the upper and lower relay female terminal portions 2, 2 to perform interlayer connection.

The pressure contact terminal 20 of the present invention can be used independently in addition to the interlayer connection. In that case, the relay female terminal portion 2 can be used.
Alternatively, a pressure contact terminal or a crimping terminal (not shown) may be formed as an input / output portion for branch connection.

Further, as shown in FIG. 3, the small-diameter electric wire 16 can be pressed against the small press-contact piece 5 of the press-contact terminal 20 to perform multi-branching.

Further, in the above-described embodiment, if a large number of the large-diameter electric wire pressure contact members 10 are prepared in accordance with electric wires of various diameters, many pressure contact terminals 20 can be easily manufactured by sharing the terminal body 1. Further, since it is not necessary to weld the pressure contact terminal to the input / output portion by laser welding or the like as in the conventional case, welding equipment is also unnecessary.

[Effect of device]

As described above, according to the present invention, various kinds of electric wires can be handled by connecting the electric wire pressure contact member prepared according to the electric wire diameter to the common terminal body. Therefore, unlike the conventional case, it is not necessary to prepare many kinds of pressure contact terminals according to the wire diameter, the manufacturing cost is low, and the management and the like are easy.
