  The present invention relates to a terminal block that can be used for various purposes, a noise filter device to which the terminal block is attached, and an inverter device having the noise filter device.

  Conventionally, for example, a noise filter device has been inserted between a load device such as an inverter device that drives a motor or the like and a power source to prevent the noise from the load device serving as a noise generation source of conduction noise or radiation noise. (See, for example, Patent Document 1).

  As is well known, for example, a terminal block attached to a metal case (housing) is used for the electrical connection between the noise filter device and the external circuit.

JP-A-10-107571

  By the way, as a structure of a terminal block, in the case of a small single phase type noise filter device, for example, as shown in FIG. 8, a terminal block 200 to which three terminals can be attached is used.

  As shown in FIG. 9, the terminal block 200 includes three pedestal portions 202a to 202c provided in parallel. These pedestal portions 202a to 202c each have an upper surface 201 and a lower surface 203, and among these pedestal portions 202a to 202c, screws 204 having a short thread length are screwed into the upper surfaces of the left and right pedestal portions 202a and 202c, respectively. A screw hole 206 is provided, and an opening 210 through which a screw 208 having a long screw part length is inserted is provided on the upper surface of the central pedestal part 202b. Moreover, the opening 212 is provided only in the lower surface of the center base part 202b among the lower surfaces of each base part 202a-202c. A ground terminal 214 is attached to the center pedestal 202b, a first electrode terminal 216a is attached to the left pedestal 202a, and a second electrode terminal 216b is attached to the right pedestal 202b. The terminals 214, 216a and 216b are attached by screws.

  Specifically, first, as shown in FIG. 9, the terminal block 200 is placed on a metal plate 218 having a ground potential. For the ground terminal 214, the screw 208 is inserted from below the metal plate 218 through the screw insertion hole 220 toward the center pedestal portion 202b, and the lower surface opening 212 and the upper surface opening of the pedestal portion 202b. A screw 208 is inserted through 210, inserted into a screw insertion hole (not shown) of the ground terminal 214 placed on the upper surface of the pedestal portion 202 b, and fixed by a nut 222. By this fixing, the terminal block 200 itself is also fixed to the metal plate 218. The first and second electrode terminals 216a and 216b are placed on the upper surfaces of the corresponding pedestal portions 202a and 202c, respectively, and the screws 204 are respectively attached to the upper and lower surfaces 201 of the pedestal portions 202a and 202c. The second electrode terminals 216a and 216b are fixed by being screwed into the screw holes 206 of the pedestals 202a and 202c through screw insertion holes (both not shown).

  That is, in the terminal block 200, the central pedestal portion 202b functions as a pedestal portion dedicated to the ground terminal, and also functions as a fixing portion for fixing the terminal block 200 to the metal plate 218. Therefore, the screw insertion hole 220 of the metal plate 218 needs to be formed in accordance with the position of the terminal block 200 placed on the metal plate 218, particularly the position of the central pedestal portion 202b, which limits the degree of freedom of design. There is a problem of being.

  Further, the electrode terminals are substantially attached only to the left and right pedestal portions 202a and 202c, and can be applied only to the single-phase circuit. In addition, since the central pedestal portion 202b is dedicated to the ground terminal and is used for fixing the terminal block 200, an electrode terminal cannot be attached, and it can be used only as a 2P terminal block.

  The present invention has been made in consideration of such problems, and provides a terminal block that can set the mounting position of the ground terminal to an arbitrary pedestal portion and can improve the degree of freedom in design. With the goal.

  Another object of the present invention is to provide a terminal block that can be attached to an electrode terminal in place of the ground terminal in addition to the above-described object in which the ground terminal can be replaced. It is in.

  Another object of the present invention is to provide a noise filter device and an inverter device that can improve the degree of freedom in design related to fixing of terminal blocks and wiring, and can be adapted to various connection forms. There is.

  The terminal block according to the present invention is a terminal block having a plurality of pedestal portions to which terminals are respectively attached, wherein each pedestal portion has a configuration in which a metal fitting for fixing the terminal block is detachable. And

  Thereby, a metal fitting can be attached to arbitrary base parts. That is, the fixed position of the terminal block can be arbitrarily set for each pedestal portion, and the degree of freedom in design related to the mounting of the terminal block can be improved.

  The pedestal is provided with a terminal on the upper surface, an opening on the lower surface, and an insertion hole into which a part of the metal fitting is inserted on a side surface. The metal fitting is located above the upper surface of the pedestal. An upper part that is disposed, a lower part that is inserted into the insertion hole of the pedestal part and is disposed on the upper side of the lower surface of the pedestal part, and provided at the lower part, and from below the pedestal part It has a screw hole into which the screw member inserted through the opening is screwed.

  Since the opening is provided in the lower surface of each pedestal portion, the screw member can be screwed into the lower portion of the metal fitting regardless of the pedestal portion attached to the metal fitting. Moreover, since the upper portion of the metal fitting is disposed on the upper side of the upper surface of the pedestal portion, it is electrically connected to a terminal attached to the upper surface of the pedestal portion.

  Thus, the fixed position of a terminal block can be arbitrarily set for every base part. Therefore, for example, when fixing the terminal block on the metal plate, even if an insertion hole (screw insertion hole) through which the screw member can be inserted is provided at an arbitrary position of the metal plate, the terminal block is fixed to the metal plate. It is possible to improve the degree of design freedom regarding the mounting of the terminal block.

  For the pedestal portion to which the metal fitting is attached, the screw member, the metal fitting and the terminal are electrically connected. If the screw member is fixed to, for example, the ground potential, the terminal of the pedestal portion is used as the ground terminal. Will work. In this case, since the metal fitting can be attached to an arbitrary pedestal portion of the terminal block, the ground terminal can be set at an arbitrary position, and the degree of freedom in designing the wiring can be improved.

  Moreover, since the said metal fitting is detachable, if a metal fitting is not attached, an electrode terminal can be attached instead of a ground terminal. That is, in addition to being able to attach a ground terminal, an electrode terminal can be attached instead of the ground terminal, and various applications can be handled.

  And in the said structure, the mark which shows an earth | ground may be displayed on the said metal fitting in the exposed part. Thereby, it is possible to confirm at a glance which terminal is connected to the ground, and it is possible to prevent erroneous wiring in advance.

In this case, if the lead portion of the terminal has a bent shape in the middle thereof, the distance between the terminal block and the wiring board can be reduced, which is advantageous in making the device itself compact. In addition, if the step of the lead portion is formed so that it can be inserted into the mounting hole of the wiring board, when the terminal block is fixed to, for example, a metal plate, the stepped portion of the wiring board and the lead wire is The terminal block can be stably fixed to the metal plate, and the lead portion is also stably fixed to the wiring board.

  Moreover, the said structure WHEREIN: You may make it have a support part which integrates these base parts in parallel. In this case, it is preferable that the rear portion of the support portion has an attachment portion into which a part of the housing of the device is fitted. This is because, for example, even if one of the left and right pedestal portions is fixed to a metal plate and is fixed at an unbalanced point as a fixing point, the terminal block is a fixed base (for example, a metal plate). Therefore, the terminal block can be stably fixed.

  In the above configuration, the terminal is attached to the upper surface of the pedestal portion by a screw member, the support portion has a partition portion between the pedestal portions, and the partition portion is the screw for attaching the terminal. You may make it have a recessed part in the location corresponding to a member.
