Description

  The present invention relates to a snubber capacitor.

  An electric circuit or an electric system is affected by a malfunction or deterioration due to an overvoltage (hereinafter referred to as a surge voltage) that occurs instantaneously or intermittently exceeding a normal voltage. In order to absorb this surge voltage, for example, a snubber capacitor disclosed in Patent Document 1 is used.

  Patent Document 1 discloses a snubber capacitor in which small-capacitance capacitor elements are arranged in parallel at intervals, and terminals derived from diagonal positions are arranged to extend upward. In this way, by reducing the capacitance per capacitor element, the total surface area of the capacitor as a whole becomes larger than when a large-capacity capacitor element is provided, so that a high heat dissipation effect can be obtained. Further, by deriving the terminal from the diagonal position, it is possible to make the load of the voltage applied to each capacitor element uniform.

However, in the snubber capacitor described in Patent Document 1, since the terminals are arranged from the diagonal position and extend upward, the power path formed by both terminals via the capacitor element becomes long. The enclosed area becomes wider. Therefore, there is a problem that the inductance is increased and the absorption of the surge voltage is hindered.
JP 2003-133172 A

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a snubber capacitor that reduces inductance that hinders surge voltage absorption.

  The invention according to claim 1 has a capacitor element and at least a pair of terminals connected to the capacitor element, and the pair of terminals is led out along any surface of the capacitor element in a direction in which the terminals approach each other. And a snubber capacitor led in a direction perpendicular to any one of the surfaces.

  As a result, the distance between the part led out along either surface of both terminals and the capacitor element can be shortened, and the distance between the parts extending in the vertical direction of both terminals can be shortened. And the area surrounded by the power path passing through both terminals becomes smaller. Therefore, by changing the arrangement of the terminals, the inductance can be reduced at low cost, and the absorption of the surge voltage can be improved.

  Further, an insulator may be disposed between a pair of terminals led out in the vertical direction.

  Thereby, it is not necessary to ensure insulation depending on the distance between the two terminals, and the portions extending in the vertical direction of both terminals can be brought close to each other. Therefore, the area surrounded by the power path passing through the capacitor element and both terminals can be minimized.

  The pair of terminals may be derived from the same position with respect to the direction parallel to the end face of the capacitor element.

  Thereby, the electric power path formed by both terminals via the capacitor element can be shortened as compared with, for example, a case where the power path is derived from the diagonal position. Therefore, the area surrounded by the power path is also reduced, and the inductance can be reduced.

  The invention according to claim 4 has a plurality of capacitor elements connected in parallel and at least a pair of terminals connected to the capacitor elements, and the pair of terminals are either of the capacitor elements in a direction in which the terminals approach each other. The snubber capacitor is derived along one of the surfaces and is derived in a direction perpendicular to any one of the surfaces.

  As a result, even when a plurality of capacitor elements are connected in parallel, the distance between the portion derived along the surfaces of both terminals and the capacitor element is short, and the distance between the portions extending in the vertical direction of both terminals. The area surrounded by the power path that passes through the capacitor element and both terminals can be reduced. Therefore, by changing the arrangement of the terminals, the inductance can be reduced at low cost, and the absorption of the surge voltage can be improved.

  The pair of terminals may be derived from the same position with respect to the arrangement direction of the capacitor elements.

  As a result, the power path formed by both terminals via the capacitor element can be shortened as compared with, for example, a case where the power path is derived from the diagonal position as in the prior art. Therefore, the inductance can be reduced at low cost simply by changing the arrangement of the terminals.

  Further, the pair of terminals may be derived from the central position with respect to the overall length of the plurality of capacitor elements in the arrangement direction of the capacitor elements.

  Thereby, the difference of the length of the electric power path with respect to each capacitor element becomes small, and the voltage load applied to each capacitor element can be made uniform.

  Further, an insulator may be disposed between a pair of terminals led out in the vertical direction.

  Thereby, it is not necessary to ensure insulation depending on the distance between the two terminals, and the portions extending in the vertical direction of both terminals can be brought close to each other. Therefore, the area surrounded by the power path passing through the capacitor element and both terminals can be minimized.

  Alternatively, the capacitor element may be housed in a case, the case may be filled with resin, and the pair of terminals may be led out from the case.

  Further, a plurality of capacitor elements may be arranged in parallel to the longitudinal direction of the case and accommodated in the case, the case may be filled with resin, and the pair of terminals may be led out from the case.

  Further, the second part of the first terminal may be arranged perpendicular to the first end face, and the second part of the second terminal may be arranged perpendicular to the second end face.

  Thereby, the second part is arranged at the same position with respect to the parallel direction of the first end face or the second end face. Therefore, the power path passing through the first terminal, the capacitor element, and the second terminal can be shortened as compared with, for example, a case where the power path is derived from the diagonal position, and the area surrounded by the power path is also reduced.

  A snubber capacitor according to an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is not limited by the following Example, All the aspects which embody the idea of this invention are included.

  FIG. 1 is a schematic perspective view showing the internal structure of the snubber capacitor in Embodiment 1 of the present invention. The snubber capacitor of this embodiment has a capacitor element 11 formed in a substantially flat shape and a pair of plate-like terminals 51a and 51b that form a U-shape and an inverted U-shape in front view.

  The first terminal 51a is composed of four parts (31a to 34a). One end of the first portion 31a is connected to the electrode surface 21a at the center position in the longitudinal direction of the electrode surface 21a of the capacitor element 11. The second part 32 a extends from the other end of the first part 31 a, and is arranged in parallel to the electrode surface 21 a and close to the upper surface of the capacitor element 11. The third portion 33 a extends from the other end of the second portion 32 a and is disposed perpendicular to the upper surface of the capacitor element 11. The fourth part 34a is provided with a connection hole 41a for connecting to an external element such as a switching element at the center position, and extends from the other end of the third part 33a and is arranged in parallel with the second part 32a. Yes.

  Similarly, the second terminal 51b is also composed of four parts (31b to 34b). One end of the first part 31b is connected to the electrode surface 21b at the center position in the longitudinal direction of the electrode surface 21b of the capacitor element 11. The second portion 32b extends from the other end of the first portion 31b, and is arranged on the same straight line as the second portion 32a of the first terminal 51a so as to be perpendicular to the electrode surface 21b and close to the upper surface of the capacitor element 11. Yes. The third portion 33b extends from the other end of the second portion 32b, and is disposed perpendicular to the upper surface of the capacitor element 11 so as to face the third portion 33a of the first terminal 51a. And the 4th site | part 34b is provided with the connection part hole 41b in the center position, and is arrange | positioned in parallel with the 2nd site | part 32b while extending from the other end of the 3rd site | part 33b.

  FIG. 2 is a cross-sectional view of a conventional terminal arrangement. The first terminal 151 a and the second terminal 151 b are linear terminals arranged in parallel with the electrode surfaces 21 a and 21 b of the capacitor element 11. An area 71 surrounded by a power path 70 passing through the first terminal 151a, the capacitor element 11, and the second terminal 151b is a rectangular region.

  On the other hand, FIG. 3 is a cross-sectional view of the snubber capacitor in FIG. An area 171 surrounded by a power path 170 passing through the first terminal 51a, the capacitor element 11, and the second terminal 51b is shown. Since the second portions 32a and 32b and the upper surface 20 of the capacitor element 11 are close to each other and the distance between the third portions 33a and 33b is short, the area 171 is smaller than that in FIG. In addition, since both the first terminal 51a and the second terminal 51b are arranged at the center position in the longitudinal direction of the electrode surfaces 21a and 21b, the power path 170 passing through the capacitor element 11 is compared with the case where the first terminal 51a and the second terminal 51b are arranged at positions shifted from the center. It's short.

  Thus, in this embodiment, the area surrounded by the power path can be reduced as compared with the conventional case, and the inductance that increases in accordance with the area can also be reduced. Therefore, the absorption of surge voltage is improved and the electric circuit can be effectively protected.

  Further, the size occupied by the entire snubber capacitor including the first terminal 51a and the second terminal 51b is not different from the case where the conventional terminal arrangement shown in FIG. 2 is used. There is no change.

  FIG. 4 is a schematic perspective view showing the internal structure of the snubber capacitor according to the second embodiment of the present invention. The differences from the first embodiment are the second portion 132a of the first terminal 251a, the second portion 132b of the second terminal 251b, and the insulating plate 60. Hereinafter, description of the same reference numerals is omitted.

  Similarly, the second part 132b of the second terminal 251b is arranged on the same straight line as the second part 132a of the first terminal 251a, perpendicular to the electrode surface 21b and close to the upper surface of the capacitor element 11. One end thereof extends from the other end of the first portion 31 b and reaches a position close to the center of the capacitor element 11.

  Due to the arrangement of the second portions 132a and 132b, the distance between the third portions 33a and 33b is shorter than that in the first embodiment.

  The insulating plate 60 is inserted between the third portions 33a and 33b. In detail, as shown in FIG. 5, it is comprised from the plane board 61, the 1st support part 62a, and the 2nd support part 62b. The height of the flat plate 61 is higher than that of the third portions 33a and 33b, and the width thereof is wider than that of the third portions 33a and 33b. The flat plate 61 is fixed by the first support part 62a and the second support part 62b. The first support part 62a and the second support part 62b have a width wider than the distance between the third portions 33a and 33b, and play a role of preventing the flat plate 61 from shifting. The insulating plate 60 may be made of any material and any shape as long as the insulation between the terminals 251a and 251b can be secured against the voltage applied to the snubber capacitor.

  As described above, the presence of the insulating plate 60 eliminates the need to ensure insulation by providing a distance between the first terminal 251a and the second terminal 251b. Therefore, since the third portions 33a and 33b can be brought close to each other, the area surrounded by the power path passing through the first terminal 251a, the capacitor element 11, and the second terminal 251b can be minimized. Therefore, the generated inductance can be minimized and the absorption of surge voltage is greatly improved.

  In addition, the size occupied by the entire snubber capacitor including the first terminal 251a, the second terminal 251b, and the insulating plate 60 is the same as when the conventional terminal arrangement shown in FIG. 2 is used. There is no need to change the arrangement of elements.

  In addition, by fixing the flat plate 61 with the first support part 62a and the second support part 62b, the insulation between the first terminal 251a and the second terminal 251b is achieved without shifting even when the snubber capacitor is moved back and forth. Can be secured.

  As described above, since both the first terminal 251a and the second terminal 251b are arranged at the same position M, for example, compared to the case where the terminals are derived from the diagonal position as in the prior art, the power path passing through the capacitor elements 11 and 12 Is short. Further, the second portions 132a and 132b and the upper surface of the capacitor element 11 are close to each other, and the third portions 33a and 33b can be made close to each other by inserting the insulating plate 60. Therefore, the area surrounded by the power path can be minimized, and the generated inductance can be minimized.

  In addition, the size of the entire snubber capacitor including the first terminal 251a, the second terminal 251b, and the insulating plate 60 is the same as the case where the terminal is derived from the diagonal position as in the prior art, so the area of the electric circuit increases. In addition, the arrangement of elements is not changed.

  In the present embodiment, the first terminal 251a and the second terminal 251b are arranged at the position M on the capacitor element 11, but the same effect can be obtained even if the position is changed in accordance with the arrangement of the circuit. In the case where there is no restriction on the arrangement of the circuit, it may be derived from the center position N of the two capacitor elements 11 and 12. Thereby, the length of the electric power path with respect to each capacitor element 11 and 12 becomes equal, and the load of the voltage concerning each capacitor element 11 and 12 can be made uniform.

  Further, in this embodiment, the pair of terminals 251a and 251b are arranged, but as shown in FIG. 7, a plurality of pairs of terminals may be arranged. Hereinafter, description of the same reference numerals is omitted.
