Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crimp terminal that is screwed and fixed onto a terminal block.

[0002]

[Prior art]

 Conventionally, when connecting a cord of an electric device to a terminal block provided at a connection point of an electric circuit, the cord is connected via a crimp terminal 1 as shown in FIG. 2 in order to facilitate electric connection. The crimp terminal 1 is formed by punching a metal plate or the like. The crimp terminal 1 includes a forked (or annular) ground portion 1A fixed to the terminal block 2 by a set screw 3 and a lead wire tip portion 5 of the cord 4. And a pipe-shaped cord connecting portion 1B to be inserted and connected. The crimp terminal 1 and the cord 4 are connected by inserting the leading end 5 of the lead wire into the cord connecting portion 1B and then crushing the cord connecting portion 1B with a tool or the like.

There are various sizes of the crimping terminal 1 depending on the diameter of the cord 4 to be connected and the screw hole diameter of the terminal provided on the terminal block side. I had to prepare a crimp terminal of the size. In addition, since the distance between the partition walls 6 protruding on the terminal block 2 to prevent contact between adjacent crimp terminals is also determined by the screw hole diameter of the terminal, it is assumed that the size of the screw hole diameter is larger than the screw hole diameter of the terminal. When the crimp terminal 1 ′ was used, it could not be connected and fixed to the terminal block 2 because it was disturbed by the partition wall 6. Further, when a crimp terminal having a size smaller than the terminal was used, the groove width of the bifurcated earth portion 1A was smaller than the screw hole diameter, so that it was naturally impossible to connect and fix it.

[0004]

[Problems to be solved by the device]

 As mentioned above, it is necessary to prepare the crimp terminal 1 of a size that matches the screw hole diameter of the terminal, but if this is done, the types of crimp terminals will increase, and the manufacturing and management of the crimp terminals will be troublesome, and the cost will increase. There was an inconvenience.

The present invention has been made in view of the above-described conventional problems, and an object thereof is to be commonly used for terminals of various sizes, reducing the number of types and manufacturing. It is to provide a crimp terminal designed to reduce cost.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a terminal width varying portion at the base of a grounding portion that is branched into two.

[0007]

[Action]

 In the present invention, the terminal width variable portion forms a slack portion that can be extended and contracted, and the width of the ground portion is changed by being extended or crushed according to the screw hole diameter of the applicable terminal.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a crimp terminal according to the present invention. In the figure, the crimp terminal 10 is formed by stamping a metal plate, and thus connects the grounding portion 10A that is branched into two forks, the cylindrical cord connecting portion 10B, and the grounding portion 10A and the cord connecting portion 10B. And a terminal width varying portion 11 is provided at the base of the grounding portion 10A. The terminal width varying portion 11 is formed by bending a part of a plate portion 12c provided between the bases of the ground portions 10A, that is, the ends of the branch portions 12a and 12b on the cord 4 side in an inverted U shape. As a result, a slack portion is formed, and when used, the terminal width W of the crimp terminal 10 can be freely variably set by being stretched or crushed according to the screw hole diameter of the applicable terminal. When increasing the terminal width W, the left and right branch portions 12a and 12b may be pulled by hand in a direction in which they are separated from each other to extend the terminal width variable portion 11, and conversely, when reducing W, the terminal width may be adjusted with pliers or the like. It suffices to crush the variable portion 11 to reduce its width w1. Note that such a change in the terminal width W is simple and easy because the crimp terminal 10 itself is made into a thin piece of metal. The terminal width varying portion 11 is provided with the base portion 12c of the earth portion 10A while avoiding the connecting portion 10C.

The crimp terminal 10 having such a configuration can be used in common for terminals of various sizes having different screw hole diameters by expanding and contracting the variable terminal width portion 11. The number of types can be reduced. If the width w1 of the terminal width varying portion 11 is narrowed after the terminal is connected and the set screws are sandwiched by the branch portions 12a and 12b, the effect of preventing the crimp terminal from coming off can be improved.

In the above embodiment, the terminal width varying portion 11 is provided so as to project upward, but the present invention is not limited to this, and a U-shaped terminal having the same plane as the ground portion 10A. It is also possible to use a variable width portion. However, when it is provided so as to project upward, there is an advantage that it can be used as a connecting portion of the probe tip portion such as an crocodile clip when measuring characteristics with a measuring instrument such as a voltmeter.

[0011]

[Effect of device]

 As described above, the crimp terminal according to the present invention is provided with the terminal width variable portion at the base of the bifurcated ground portion, and the width of the crimp terminal can be changed according to the terminal screw hole diameter by extending or crushing the variable portion. Since it is configured so that it can be set, it can be commonly used for various terminals with different screw hole diameters, and the number of crimp terminals can be reduced. Therefore, it is easy to manage parts for crimp terminals, reduce manufacturing cost, and even crimp terminals with large terminal width can be attached to terminal blocks with small partition walls. There is a big effect.
