JPH1079268A - Screw tightening terminal for wiring - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable use in connection of tow or more crimp contact terminals by intervening an intermediate washer having its proper thickness between a press washer and a terminal plate. SOLUTION: An example of connecting three crimp contact terminals 7 is explained. An intermediate washer 3 of a terminal screw 1 has its thickness required for the size of one crimp contact terminal 7. Two crimp contact terminals 7 are connected between the intermediate washer 3 and a terminal plate 4, and further one crimp contact terminal 7 is connected between a press washer 2 and the intermediate washer 3. The intermediate washer 3 employs, for example, a metal of material similar to that of the press washer 2 with good conductivity and good contact property and a bottom face shape is formed in a rectangular shape whose size is similar to the press washer 2. The press washer 2 and the terminal plate 4 may be similar to those for a conventional screw tightening terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw terminal for wiring which can be used to connect more than two crimp terminals.

[0002]

2. Description of the Related Art A conventional screw terminal for wiring is such that a terminal screw 1 is screwed to a terminal plate 4 via a holding washer 2 as shown in FIG.

[0003]

When a conventional screw terminal for wiring is used in a structure as shown in FIGS. 7 and 8, when it is used, connection of more than two crimp terminals as shown in FIG. Could not be used. The present invention solves this problem, and an object of the present invention is to provide a screw terminal for wiring that can be used to connect more than two crimp terminals.

[0004]

In order to achieve the above object, a screw terminal for wiring according to the present invention has an intermediate washer having an appropriate thickness interposed between a presser washer and a terminal plate. .

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A structure in which an intermediate washer having an appropriate thickness is interposed between a presser washer and a terminal plate allows connection of up to two crimp terminals between the intermediate washer and the terminal plate. In addition, up to two crimp terminals can be connected between the presser washer and the intermediate washer. Therefore, the screw terminal for wiring of the present invention can be used for connection of more than two crimp terminals.

[0006]

An embodiment will be described with reference to the drawings. In FIG. 1 to FIG. 4, the terminal screw 1 has a male screw portion 11 longer than that of a conventional screw terminal for wiring by the thickness of the intermediate washer 3 and the crimp terminal. The presser washer 2 may be the same as the presser washer of the conventional screw terminal for wiring.
The intermediate washer 3 is made of, for example, a metal of the same material as the presser washer 2 having good conductivity and contactability, and has a bottom surface formed in a square shape having the same dimensions as the presser washer 2. The terminal plate 4
It may be the same as the terminal plate of the conventional screw terminal for wiring. In FIG. 5, the intermediate washer 3 has a thickness required for one crimp terminal, and connects two crimp terminals between the intermediate washer 3 and the terminal plate 4. The figure shows that one crimp terminal is connected between them. FIG.
In the above, the intermediate washer 3 has a thickness required for two crimp terminals, two crimp terminals are connected between the intermediate washer 3 and the terminal plate 4, and further, between the presser washer 2 and the intermediate washer 3. This shows that two crimp terminals are connected. Further, a plurality of intermediate washers may be provided so that more crimp terminals can be connected. The connection of the crimp terminal has been described above, but the screw terminal for wiring of the present invention may be used for connection of a wire or connection of a short-circuit plate.

[0007]

Since the screw terminal for wiring of the present invention can be used for connection of more than two crimp terminals, it is possible to make branch wiring in the middle of continuous crossover wiring in a power supply terminal and the like, and furthermore, a common terminal. In such a case, high-density wiring can be achieved, and the labor of the wiring work can be saved.
