Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a terminal structure of a noise filter.

[0002]

[Prior Art]

 As shown in FIGS. 6 to 11, a conventional noise filter e is composed of a combination of a base plate a1 and a lid part a2 having a recess a3 in a side plate, and has a screw terminal b1 and a lead terminal b such as a fast tab tab b2. The terminal plate c (see FIG. 10) provided with the mounting holes b3 and b4 corresponding to the type is attached to the recess a3 of the lid a2.

When the insulating bushing d (see FIGS. 8, 9, and 11) is used, the side plate of the lid a2 is directly provided with the mounting hole a5 to assemble the various lead terminals b. ..

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, the terminal plate and the insulating bushing must be manufactured to correspond to the screw terminal and the faston tab terminal, respectively. Also, since there are two types of terminal plates or insulating bushings, one for screw terminals and the other for faston tab terminals, there is a problem that the number of parts increases and the manufacturing and management of parts become complicated. ..

Further, there is a problem in that two types of molds, that is, a terminal plate for a screw terminal and a terminal plate for a faston tab terminal or an insulating bushing are required, and the initial cost becomes high.

Therefore, the present invention has been devised in view of the above-mentioned problems of the conventional technology, and provides a terminal structure of a noise filter that can be commonly used for a screw terminal and a faston tab terminal with a single terminal plate. Has a purpose.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the terminal structure of the noise filter according to the present invention, the noise filter which is a combination of the lid portion and the base plate having the rectangular concave portion on the side plate and the screw terminal hole on one plate. In addition to drilling, the other plate is also provided with a faston tab terminal hole, and two plates with a diameter slightly larger than the recess are arranged with the screw terminal hole and the faston tab terminal hole in the opposite direction. Terminal plate that is welded in parallel via a connecting plate that has almost the same width as the recess and the screw terminal or faston tab terminal that is assembled in the screw terminal hole and faston tab terminal hole. It is something.

[0008]

[Action]

 Slide both ends of the connecting plate into the recesses of the lid to insert the terminal plates, and then assemble screw terminals or faston tab terminals in the screw terminal holes and faston tab terminal holes, respectively. Further, the screw terminal or the faston tab terminal may be attached to the terminal board in advance.

When attaching a different type of lead terminal to the terminal plate, the terminal plate is inserted into the recess while being rotated 180 degrees (see FIG. 2).

[0010]

【Example】

 An embodiment will be described with reference to FIGS. 1 to 5. The noise filter 1 is composed of a combination of a lid portion 1b and a base plate 1a, and a side plate 12 of the lid portion 1b is provided with a rectangular concave portion 11. Then, both are fixed by fixing screws 5.

The terminal plate 2 is composed of two plates 2 a and 2 b having a diameter slightly larger than that of the recess 11 and having substantially the same size, and a connecting plate 23 connecting the two plates 2 a and 2 b. A screw terminal hole 21 is formed in the one plate 2a, and a faston tab terminal hole 22 is formed in the other plate 2b.

When different lead terminals are used, the terminal holes 21 and the faston tab terminal holes 22 are provided corresponding to the lead terminals to be used.

As shown in FIG. 1, the two plates 2 a and 2 b have screw terminal holes 21 and faston tab terminal holes 22 arranged in opposite directions so that the end portions overlap each other and have substantially the same width as the recess 11. It is welded in parallel via the connecting plate 23.

Then, as shown in FIG. 2, one terminal plate 2 is rotated by 180 degrees so as to be shared depending on the type of the lead terminal.

Further, the screw terminal 3 or the faston tab terminal 4 is attached to the screw terminal hole 21 and the faston tab terminal hole 22.

When the insulating bushing 5 is mounted, an insulating bushing mounting hole (not shown) is provided in place of either the terminal hole 21 or the faston tab terminal hole 22.

[0017]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. A. Since one terminal plate can be shared by another lead terminal simply by rotating it by 180 °, efficiency can be improved by reducing the number of parts and the range of application of the noise filter can be expanded.

B. Since the mold for the terminal board is only one set, the mold cost can be reduced. Therefore, higher economy can be achieved.
