Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a weld nut for attaching lead terminals.

(Prior Art) Conventionally, when attaching this type of lead terminal 20 to a plate member 10 made of a steel plate or the like by providing a terminal block 21, in order to prevent the lead terminal 20 from rotating, (a) the terminal block 21, as shown in FIGS. 5 and 6, a substantially L-shaped bracket 22 is provided, and a vertical piece 23 of this bracket 22 is burred with a press to form a neck portion 24. A screw is threaded on the inner diameter, and a protrusion 25 for preventing the lead terminal 20 from rotating is provided on the upper side of the vertical piece 23, and a mounting piece 26 is provided.
(b) In place of the above-mentioned neck part 24, a weld nut 2 as shown in FIGS. 7 and 8 is used.
There is also a structure in which a lead terminal 20 is attached as shown in FIGS. 9 and 10 (c).
When the nut 28 is attached to the nut 28, there is a structure in which wall members 29 for preventing rotation are attached to both sides of the nut 28.

(Problems to be solved) However, with the configurations (a) and (b) above, the material cost, processing cost, etc. are high, and the lead terminals are installed from the side, making installation difficult. In the case of (c), although the installation was good, there were problems such as high cost.

(Means for Solving the Problems) The present invention was made to solve the above-mentioned conventional problems, and it is possible to prevent rotation of the lead terminals, reduce costs, and prevent the lead terminals from rotating. The purpose of the nut is to provide a weld nut for attaching lead wire terminals with good installation performance, and its gist is to provide a weld nut for attaching lead terminals that has a welding protrusion on the bottom surface of the main body, and a fixing part for the lead terminal on the top surface of the main body. The lead terminal mounting weld nut has a structure in which a recess into which the lead terminal is embedded and a suitable number of regulation recesses into which the lead terminal mounting portion is fitted are provided continuously to the recess.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is a lead wire, and a lead terminal 2 is attached to the end of the lead wire 1. This lead terminal 2 has a circular fixing part 3 and a part of this fixing part 3 is formed with a tubular attaching part 4 to which the lead wire 1 is attached.
is electrically connected to.

A weld nut 5 serves as a terminal block for attaching the lead terminal 2, and is welded to a plate member 10 such as a steel plate. Welding protrusions 6 are provided protruding from each side corner.
In addition, a circular recess 8 into which the fixing part 3 of the lead terminal 2 can be fitted in a substantially buried manner is provided approximately at the center of the upper surface 7 of the nut 5. Fit the mounting portion 4 of the terminal 2 in a fitting manner and orient the mounting direction of the lead terminal 2,
In addition, a groove-shaped regulating recess 9 for regulating rotation is provided in an opening shape to the side. Moreover, a female threaded portion 12 into which a mounting screw 11 is screwed is screwed approximately at the center of the recessed portion 8 . The weld nut 5 thus formed is attached to the plate member 1 by projection welding.
It is attached to 0.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the weld nut 5 of this example has a welding protrusion 6 on the lower surface of the main body, and the upper surface 7 of the main body has a recess 8 into which the fixing part 3 of the lead terminal 2 is embedded, and a lead connected to the recess 8. A regulating recess 9 into which the mounting portion 3 of the terminal 2 can be fitted is provided in a laterally open shape. Therefore, lead terminal 2
For installation, the fixing part 3 and the mounting part 4 are fitted into the recess 8 and the regulating recess 9 formed on the upper surface 7 of the weld nut 5, and the mounting screw 11 is inserted into the female thread part 12.
It can be installed by screwing into the

As described above, according to the weld nut 5 of this example, the recess 8 into which the lead terminal 2 can be fitted is formed on the upper surface.
Since the bracket 22 is specially provided and a protrusion 25 for preventing rotation is formed on the bracket 22 as in the conventional configuration, or a wall member 29 for preventing rotation is provided. It is not necessary and can be easily and firmly attached by fitting into the recesses 8 and 9 from above.
Further, the regulating recess 9 prevents the lead terminal 2 from rotating, and the regulating recess 9 directs the lead wire 1 in the direction in which it is attached, improving electrical and mechanical reliability. Moreover, this weld nut 5 has many features such as being able to reduce costs because it facilitates header processing with good productivity due to its shape.

In addition, Fig. 3 and Fig. 4 are for weld nut 5.
The nut 5A shown in FIG. 3 has regulating recesses 9 in two directions, and the nut 5B in FIG. 4 has regulating recesses 9 in four directions. The structure is the same as that of the weld nut 5 described above. Therefore, these weld nuts 5A and 5B also have the same effect as the weld nut 5 described above.

Further, in the above embodiment, the recess 8 is formed into a circular shape, but the recess 8 is not limited to this, and any shape may be used as long as the recess 8 can be fitted into the recess 8 . Further, the location and direction in which the regulating recess is provided can be arbitrarily selected.

(Effect of the invention) The present invention is a weld nut for attaching a lead wire terminal that has a welding protrusion on the bottom surface of the main body, and the top surface of the main body has a recess into which the fixing part of the lead terminal is embedded and is continuous with the recess. By providing a suitable number of restriction recesses into which the lead terminal mounting portion can be fitted, the recess into which the lead terminal can be fitted and the restriction recess are provided on the top surface, making it exceptional. There is no need to provide a member, and it can be easily inserted into the recess and regulation recess from above.
In addition, the regulating recess prevents the lead terminal from rotating, and the regulating recess directs the lead wire in the direction of installation, improving electrical and mechanical reliability. In addition, this weld nut is extremely practical as a weld nut for attaching lead terminals, as its shape facilitates header processing with high productivity, which reduces costs. This is a new idea.
