[Solution] The present invention is a connector connection device comprising: a first substrate attached to a substrate holder 21 and having a first connector receiving portion to which a first connector is connected; a first support column 21a protruding to the outside of the substrate holder 21 and having a height 82 that is greater than the thickness 81 of the first substrate 41; and a first hole 41a provided in the first substrate 41 and having an inner diameter greater than the outer diameter 21c of the first support column 21a, wherein the first hole 41a is inserted into the first support column 21a and the upper surface 21d of the first support column 21a is fixed by a first spacer 22, thereby forming a first gap 51 between the side surface 21e of the first support column 21a and the inner surface 41b of the first hole 41a, and forming a second gap 52 between the bottom 21b of the first support column 21a and the back surface 41c of the first substrate 41.

Description

TECHNICAL FIELD

[0001] The present invention relates to a connector connection device and a power supply device.

BACKGROUND ART

[0002] Conventionally, the mating connector of a rectifier unit adopts the shape of an "integrated input-output type (floating structure)", and the rectifier unit is inserted into and removed from the power supply device by a plug-in structure. In addition, when the rectifier unit is mounted, position correction using guide pins is performed before the connectors are mated in order to suppress misalignment between the connectors. A technique related to this is disclosed in Patent Document 1.

[0003] However, if an attempt is made to adopt a structure in which the mating connectors, which are non-floating on-board connectors, are separated on the input side and the output side respectively, the alignment accuracy between the connectors is not sufficient due to the angle during unit insertion, assembly tolerances on the unit side, variations in the connector pitch on the input side and the output side, and assembly tolerances on the device side, so the pins of the connectors may not be mated with high accuracy. As a result, the connectors cannot be connected to each other with high accuracy, and there is a concern about the risk of damage such as breakage of current-carrying pins. In addition, since the rectifier unit is mounted by an operator, smooth insertion and removal of the unit is required.

[0004] Accordingly, in order to absorb the above assembly tolerances, it is required that the input-side board and the output-side board of the backboard on the receiving side of the power supply device have a floating structure.

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0006] Various aspects of the present invention aim to provide a connector connection device and a power supply device that enable smooth connection and removal of a connector to the connector receiving portion of a substrate by providing a floating structure for the substrate. [Means for solving the problem]

[0007] Various aspects of the present invention will be described below.

[0008] [1] A substrate attached to a substrate holder and having a connector receiving portion to which a connector is connected, A support column protruding from the outside of the substrate holder, The substrate is provided with a hole having an inner diameter larger than the outer diameter of the support column, It has, A connector connection device characterized in that the support column is inserted into the hole, a first gap is formed between the side surface of the support column and the inner surface of the hole, and / or a second gap is formed between the bottom of the support column and the back surface of the substrate.

[0009] According to the connector connection device described in [1] above in one aspect of the present invention, a support column protruding from the outside of the substrate holder is inserted into a hole provided in the substrate, forming a first gap between the side surface of the support column and the inner surface of the hole, and / or a second gap between the bottom of the support column and the back surface of the substrate. The first gap allows the substrate to float and shift in a direction parallel to the substrate surface. The second gap reduces friction between the bottom of the support column and the back surface of the substrate, allowing the substrate to float smoothly in a direction parallel to the substrate surface. The second gap also allows the substrate to float and shift perpendicular to the substrate surface. As a result, when a connector is connected to a connector receiving portion, the floating function can absorb misalignment between connectors due to assembly tolerances on the connector side and assembly tolerances on the substrate holder side. Therefore, the risk of damage such as broken current-carrying pins can be prevented, and the connector can be smoothly connected to and removed from the connector receiving portion of the substrate.

[0010] [2] A first substrate attached to a substrate holder and having a first connector receiving portion to which a first connector is connected, A first support column protruding from the outside of the substrate holder, A first hole provided in the first substrate, having an inner diameter larger than the outer diameter of the first support column, It has, A connector connection device characterized in that the first support column is inserted into the first hole, and the upper surface of the first support column is fixed by the first spacer, thereby forming a first gap parallel to the surface of the first substrate between the side surface of the first support column and the inner surface of the first hole, and forming a second gap perpendicular to the back surface of the first substrate between the bottom of the first support column and the back surface of the first substrate.

[0011] According to the connector connection device described in [2] above in one aspect of the present invention, a first hole provided in the first substrate is inserted into a first support column protruding from the outside of the substrate holder, and the upper surface of the first support column is fixed with a first spacer, thereby forming a first gap parallel to the surface of the first substrate between the side surface of the first support column and the inner surface of the first hole, and a second gap perpendicular to the back surface of the first substrate is formed between the bottom of the first support column and the back surface of the first substrate. The first gap allows the first substrate to float and slide in a direction parallel to the substrate surface. The second gap reduces friction between the bottom of the support column and the back surface of the first substrate, allowing the first substrate to float smoothly in a direction parallel to the substrate surface. The second gap also allows the first substrate to float and slide perpendicular to the substrate surface. Furthermore, by allowing the first substrate to float and slide simultaneously in both the parallel and perpendicular directions to the substrate surface, it becomes possible for the first substrate to float and slide diagonally as well. As a result, when the first connector is connected to the first connector receptacle, the floating function described above can absorb any misalignment between the connectors caused by the assembly tolerances of the first connector and the board holder. Therefore, the risk of damage such as broken power supply pins can be prevented, and the first connector can be smoothly connected to and removed from the first connector receptacle on the first board.

[0012] [3] In the above [2], A connector connection device characterized in that the parallel dimension of the second gap is set to be smaller than the vertical dimension of the first gap.

[0013] According to the connector connection device described in [3] above in one aspect of the present invention, it is possible to smoothly connect and disconnect the first connector to the first connector receiving portion of the first substrate.

[0014] [4] In the above [2], A connector connection device characterized in that the first gap is connected to the second gap, and a third gap is formed diagonally with respect to the back surface of the first substrate.

[0015] According to the connector connection device described in [4] above in one aspect of the present invention, the first gap is connected to the second gap, and a third gap is formed diagonally with respect to the back surface of the first substrate, thereby enabling the first substrate to float and shift diagonally.

[0016] [5] In the above [2], A second substrate is attached to the substrate holder and has a second connector receiving portion to which a second connector is connected, A second support column protruding from the outside of the substrate holder, A second hole is provided in the second substrate and has an inner diameter larger than the outer diameter of the second support column, It has, A connector connection device characterized in that the second support column is inserted into the second hole, and the upper surface of the second support column is fixed by the second spacer, thereby forming a fourth gap parallel to the surface of the second substrate between the side surface of the second support column and the inner surface of the second hole, and forming a fifth gap perpendicular to the back surface of the second substrate between the bottom of the second support column and the back surface of the second substrate.

[0017] According to the connector connection device of the above [5] pertaining to one aspect of the present invention, the first board and the second board are separated, the second hole provided on the second board is inserted into the second support column protruding outward from the board holder, and the upper surface of the second support column is fixed by the second spacer, whereby a fourth gap parallel to the surface of the second board is formed between the side surface of the second support column and the inner side surface of the second hole, and a fifth gap perpendicular to the back surface of the second board is formed between the bottom of the second support column and the back surface of the second board. The fourth gap allows the second board to float and displace in the direction parallel to the board surface, and the fifth gap allows the second board to float and displace in the direction perpendicular to the board surface. Furthermore, the second board can float and displace in both the direction parallel to the board surface and the direction perpendicular to the board surface at the same time, so that the second board can also float and displace in an oblique direction. As a result, when the second connector is connected to the second connector receiving portion, positional misalignment between the connectors caused by assembly tolerances on the second connector side and assembly tolerances on the board holder side can be absorbed by the above floating function. Accordingly, the risk of damage such as breakage of current-carrying pins can be prevented, and the second connector can be smoothly connected to and disconnected from the second connector receiving portion of the second board.

[0027] According to the power supply device of

[13] described above in one aspect of the present invention, a support column protruding from the outside of the unit mounting frame is inserted into a hole provided in the substrate, forming a first gap between the side surface of the support column and the inner surface of the hole, and / or a second gap between the bottom of the support column and the back surface of the substrate. The first gap allows the substrate to float and shift in a direction parallel to the substrate surface. The second gap also allows the substrate to float and shift in a direction perpendicular to the substrate surface. Furthermore, the second gap reduces friction between the bottom of the support column and the back surface of the substrate, allowing the substrate to float smoothly in a direction parallel to the substrate surface. As a result, when the rectifier unit is inserted into the unit mounting frame and the connector is connected to the connector receiver, the floating function can absorb misalignment between the connectors due to assembly tolerances on the rectifier unit side and the unit mounting frame side. Therefore, the risk of damage such as broken current-carrying pins can be prevented, and the rectifier unit can be inserted and removed smoothly.

A power supply device characterized in that the second hole is inserted into the second support column and the upper surface of the second support column is fixed with a second spacer, thereby forming a fourth gap parallel to the surface of the output board between the side surface of the second support column and the inner surface of the second hole, and forming a fifth gap perpendicular to the back surface of the output board between the bottom of the second support column and the back surface of the output board.

The second support column, second hole, and second spacer formed on the outside of the unit mounting frame have a similar structure, and therefore the fourth gap and fifth gap are formed in the same way. The first gap and the fourth gap allow the input side substrate and the output side substrate to float and shift in a direction parallel to the substrate surface. In addition, the second gap and the fifth gap allow the input side substrate and the output side substrate to float and shift in a direction perpendicular to the substrate surface. Furthermore, the second and fifth gaps reduce friction between the bottoms of the first and second support pillars and the back surfaces of the input and output boards, allowing the input and output boards to float smoothly parallel to the board surface. In addition, the simultaneous floating and shifting of the input and output boards parallel and perpendicular to the board surface enables them to float and shift diagonally as well. As a result, when the rectifier unit is inserted into the unit mounting frame, the input connector is connected to the input connector receiver, and the output connector is connected to the output connector receiver, the floating function can absorb the misalignment of the connectors due to assembly tolerances on the rectifier unit side and the unit mounting frame side.

[0043] (First embodiment) Several embodiments of the present invention will be described below with reference to the drawings.

[0044] The connector connection device has a first substrate 41 attached to a substrate holder 21 as shown in Figure 2. This first substrate 41 has a first connector receiving portion 31a as shown in Figure 3 to which the first connector 31 shown in Figure 1 is connected. As shown in Figures 5 and 6(A), a first support column 21a protrudes from the outside of the substrate holder 21, and the height 82 of the first support column 21a is greater than the thickness 81 of the first substrate 41. The first substrate 41 is provided with a first hole 41a, and this first hole 41a has an inner diameter larger than the outer diameter 21c of the first support column 21a (see Figure 6(A)).

[0045] As shown in Figure 6(A), the first support column 21a of the substrate holder 21 is inserted into the first hole 41a of the first substrate 41, and the upper surface 21d of the first support column 21a is fixed by the first spacer 22, thereby holding the first substrate 41 in the substrate holder 21. At this time, a first gap 51 parallel to the surface of the first substrate 41 is formed between the side surface 21e of the first support column 21a and the inner surface 41b of the first hole 41a, and a second gap 52 perpendicular to the back surface 41c of the first substrate 41 is formed between the bottom 21b of the first support column 21a and the back surface 41c of the first substrate 41.

[0046] The parallel dimension 52a of the second gap 52 is preferably set to be smaller than the vertical dimension 51a of the first gap 51. This makes it possible to smoothly connect and disconnect the first connector 31 to the first connector receiving portion 31a of the first substrate 41.

[0047] According to the connector connection device described above, the first gap 51 allows the first substrate 41 to float and shift in a direction parallel to the substrate surface. Furthermore, the second gap 52 reduces friction between the bottom 21b of the support column 21a and the back surface 41c of the first substrate 41, allowing the first substrate 41 to float smoothly in a direction parallel to the substrate surface. In addition, the second gap 52 allows the first substrate 41 to float and shift in a direction perpendicular to the substrate surface. Moreover, by allowing the first substrate 41 to float and shift simultaneously in the direction parallel and perpendicular to the substrate surface, the first substrate 41 can also float and shift diagonally. As a result, when the first connector 31 is connected to the first connector receiving portion 31a, the positional misalignment between the connectors due to assembly tolerances on the first connector 31 side and the substrate holder 21 side can be absorbed by the floating function described above. Therefore, the risk of damage such as breakage of the power supply pins can be prevented, and the first connector 31 can be smoothly connected to and removed from the first connector receiving portion 31a of the first circuit board 41 (see Figures 1, 3, and 6).

[0048] As shown in Figure 6(A), the first gap 51 is connected to the second gap 52, and a third gap 53 is formed diagonally to the back surface 41c of the first substrate 41. This third gap 53 allows the first substrate 41 to reliably float and shift diagonally.

[0049] The substrate holder 21 shown in Figures 2 and 3 above is also the unit mounting frame described later, but the substrate holder 21 can also be used for purposes other than the unit mounting frame.

[0050] Furthermore, the first circuit board 41 shown in Figure 2 above is also an input-side circuit board attached to the unit mounting frame 21, which will be described later. However, the first circuit board 41 can also be used for purposes other than as an input-side circuit board attached to the unit mounting frame 21.

[0051] Furthermore, the first connector 31 shown in Figure 1 above is also the input side connector of the rectifier unit 11, which will be described later, but the first connector 31 can also be used for purposes other than the input side connector of the rectifier unit 11.

[0052] The connector connection device described below has the following configuration in addition to the connector connection device described above. The following configuration has the same configuration as the connector connection device described above and has the same effect, but will be explained in detail below.

[0053] The connector connection device has a second substrate 42 attached to a substrate holder 21 as shown in Figure 2. This second substrate 42 has a second connector receiving portion 32a as shown in Figure 3 to which the second connector 32 as shown in Figure 1 is connected. As shown in Figures 5 and 6(A), a second support column (not shown) protrudes from the outside of the substrate holder 21, and the height of this second support column is greater than the thickness of the second substrate 42. The second substrate 42 is provided with a second hole (not shown), and this second hole has an inner diameter larger than the outer diameter of the second support column (not shown). The second support column has the same structure as the first support column 21a.

[0054] The second hole of the second substrate 42 is inserted into the second support column of the substrate holder 21, and the upper surface of the second support column is fixed with a second spacer (not shown), thereby holding the second substrate 42 in the substrate holder 21. At this time, a fourth gap (not shown) parallel to the surface of the second substrate 42 is formed between the side surface of the second support column and the inner surface of the second hole, and a fifth gap (not shown) perpendicular to the back surface of the second substrate 42 is formed between the bottom of the second support column and the back surface of the second substrate 42. The second hole of the second substrate 42 has the same structure as the first hole 41a of the first substrate 41, and the second spacer has the same structure as the first spacer 22.

[0055] According to the connector connection device described above, the fourth gap allows the second substrate 42 to float and shift parallel to the substrate surface. Furthermore, the fourth gap reduces friction between the bottom of the second support and the back surface of the second substrate 42, enabling the second substrate 42 to float smoothly parallel to the substrate surface. Additionally, the fifth gap allows the second substrate 42 to float and shift perpendicular to the substrate surface. Moreover, by simultaneously floating and shifting parallel and perpendicular to the substrate surface, the second substrate 42 can also float and shift diagonally. As a result, when the second connector 32 is connected to the second connector receiving portion 32a, the floating function can absorb misalignment between the connectors due to assembly tolerances on the second connector 32 side and the substrate holder 21 side. Therefore, the risk of damage such as broken current-carrying pins can be prevented, and the second connector 32 can be smoothly connected to and removed from the second connector receiving portion 32a of the second substrate 42.

[0056] The parallel dimension of the fifth gap is preferably set to be smaller than the vertical dimension of the fourth gap. This makes it possible to smoothly connect and disconnect the second connector 32 to the second connector receiving portion 32a of the second substrate 42.

[0057] As shown in Figure 6, the fourth gap connects to the fifth gap, and a sixth gap (not shown) is formed diagonally to the back surface of the second substrate 42. This sixth gap allows the second substrate 42 to reliably float and shift diagonally.

[0058] The second circuit board 42 shown in Figure 2 above is also the output-side circuit board attached to the unit mounting frame 21, which will be described later. However, the second circuit board 42 can also be used for purposes other than the output-side circuit board attached to the unit mounting frame 21.

[0059] Furthermore, the second connector 32 shown in Figure 1 above is also the input connector of the rectifier unit 11, which will be described later. However, the second connector 32 can also be used for purposes other than the input connector of the rectifier unit 11.

[0060] As shown in Figure 2, the first substrate 41 and the second substrate 42 are separated. In this embodiment, the first substrate 41 and the second substrate 42 are separated, but the first substrate 41 and the second substrate 42 may be composed of a single substrate.

[0061] As shown in Figures 5 and 6(A) and (B), the first spacer 22 is fixed to the upper surface 21d of the first support column 21a with the first screw 71 (see also Figure 4). As shown in Figure 2, the second spacer 24 is fixed to the upper surface of the second support column (not shown) with the second screw 72. The second spacer 24, the second support column, and the second screw 72 each have the same structure as the first spacer 22, the first support column 21a, and the first screw 71, respectively.

[0062] Furthermore, as shown in Figure 6(A), the first hollow spacer 23 is inserted into the first support column 21a so that the upper part of the first hollow spacer 23 is positioned at the bottom 21b of the first support column 21a. The first hollow spacer 23 is configured to slide along the first support column 21a. A second hollow spacer (not shown) is inserted into the second support column so that the upper part of the second hollow spacer is positioned at the bottom of the second support column. The second hollow spacer is configured to slide along the second support column. The second hollow spacer has the same structure as the first hollow spacer 23.

[0063] The connector connection device described next is the case where the connector connection device described above is the power supply device 11 shown in Figure 7.

[0064] The above-mentioned substrate holder 21 is the unit mounting frame shown in Figures 2 and 3. The above-mentioned first connector 31 is the input-side connector 31 shown in Figure 1, and the above-mentioned second connector 32 is the output-side connector 32 shown in Figure 1. The above-mentioned first substrate 41 is the input-side substrate 41 shown in Figures 2 and 4. The above-mentioned second substrate 42 is the output-side substrate 42 shown in Figure 2. The above-mentioned power supply unit 11 has an input-side connector 31 and an output The unit is equipped with a rectifier unit 11 having a force-side connector 32. The unit mounting frame 21 shown in Figures 2 and 3 is configured so that the rectifier unit 11 shown in Figure 1 can be inserted into and removed from it (see Figure 7). The unit mounting frame 21 is designed to accommodate two rectifier units 11.

[0065] (Second embodiment) A power supply device according to one aspect of the present invention will be described below with reference to the drawings.

[0066] The power supply unit shown in Figure 7 has a unit mounting frame 21 from which a rectifier unit 11 can be inserted and removed. The rectifier unit 11 shown in Figure 1 has an input connector 31 and an output connector 32. As shown in Figure 2, an input board 41 and an output board 42 are attached to the unit mounting frame 21. When the rectifier unit 11 is inserted, as shown in Figures 2 and 3, an input connector receiving portion 31a is formed on the input board 41 to which the input connector 31 is connected, and an output connector receiving portion 32a is formed on the output board 42 to which the output connector 32 is connected.

[0067] As shown in Figures 5 and 6(A), a first support column 21a is provided protruding from the outside of the unit mounting frame 21, and the height of the first support column 21a is greater than the thickness 81 of the input side substrate 41. A first hole 41a is provided in the input side substrate 41, and the first hole 41a has an inner diameter greater than the outer diameter 21c of the first support column 21a. A second support column (not shown) is provided protruding from the outside of the unit mounting frame 21, and the height of the second support column is greater than the thickness of the output side substrate 42. The second support column has the same structure as the first support column 21a. A second hole (not shown) is provided in the output side substrate 42, and the second hole has an inner diameter greater than the outer diameter of the second support column. The second hole has the same structure as the first hole 41a.

[0068] As shown in Figures 4, 5, and 6(A) and (B), the first support column 21a of the substrate holder 21 is inserted into the first hole 41a of the input-side substrate 41, and the upper surface 21d of the first support column 21a is fixed by the first spacer 22, thereby holding the input-side substrate 41 in the substrate holder 21. At this time, a first gap 51 parallel to the surface of the input-side substrate 41 is formed between the side surface 21e of the first support column 21a and the inner surface 41b of the first hole 41a. In addition, a second gap 52 perpendicular to the back surface 41c of the input-side substrate 41 is formed between the bottom 21b of the first support column 21a and the back surface 41c of the input-side substrate 41.

[0069] The output-side substrate 42 is held in the substrate holder 21 by the second support column of the substrate holder 21 through the insertion of the second hole of the output-side substrate 42, and the upper surface of the second support column being fixed by the second spacer 24 (see Figure 2). At this time, a fourth gap (not shown) parallel to the surface of the output-side substrate 42 is formed between the side surface of the second support column and the inner surface of the second hole, and a fifth gap (not shown) perpendicular to the back surface of the output-side substrate 42 is formed between the bottom of the second support column and the back surface of the output-side substrate 42. The fourth gap has the same structure as the first gap 51, and the fifth gap has the same structure as the second gap 52.

[0070] The parallel dimension of the second gap 52 is preferably set to be smaller than the vertical dimension of the first gap 51, and the parallel dimension of the fifth gap is preferably set to be smaller than the vertical dimension of the third gap. This makes it possible to smoothly connect and disconnect the input-side connector 31 to the input-side connector receiving portion 31a of the input-side board 41, and to smoothly connect and disconnect the output-side connector 32 to the output-side connector receiving portion 32a of the output-side board 42.

[0071] As shown in Figure 6(A), the first gap 51 is connected to the second gap 52, and a third gap 53 is formed diagonally to the back surface 41c of the input-side substrate 41. This third gap 53 allows the input-side substrate 41 to reliably float and shift diagonally. Furthermore, the fourth gap is connected to the fifth gap, and a sixth gap (not shown) is formed diagonally to the back surface of the output-side substrate 42. This sixth gap allows the input-side substrate 41 to reliably float and shift diagonally. The sixth gap has the same structure as the third gap 53. Also, as shown in Figures 2 and 4, four floating structures are arranged on the input-side substrate 41. Also, as shown in Figure 2, four floating structures are arranged on the output-side substrate 42.

[0072] As shown in Figure 2, the input-side board 41 and the output-side board 42 are separated. In this embodiment, the input-side board 41 and the output-side board 42 are separated, but the input-side board 41 and the output-side board 42 may be composed of a single board.

[0073] As shown in Figures 4, 5 and 6(A) and (B), the first spacer 22 is fixed to the upper surface 21d of the first support column 21a with a first screw. As shown in Figure 2, the second spacer 24 is fixed to the upper surface of the second support column with a second screw 72.

[0074] Furthermore, as shown in Figure 6(A), the first hollow spacer 23 is inserted into the first support column 21a so that the upper part of the first hollow spacer 23 is positioned at the bottom 21b of the first support column 21a. The second hollow spacer (not shown) is inserted into the second support column so that the upper part of the second hollow spacer is positioned at the bottom of the second support column.

[0075] As shown in Figure 1, a first guide pin 61 is formed on the surface of the rectifier unit 11 where the input connector 31 and output connector 32 are located. As shown in Figure 3, a first guide pin insertion opening 62 is formed in the unit mounting frame 21. When the rectifier unit 11 shown in Figure 1 is inserted into the unit mounting frame 21 shown in Figure 3, the first guide pin 61 is inserted into the first guide pin insertion opening 62, thereby aligning the position of the input connector 31 with the position of the input connector receiving portion 31a. At the same time, the position of the output connector 32 with the position of the output connector receiving portion 32a is also aligned. In this way, in the power supply device shown in Figure 7, the rectifier unit 11 can be inserted into the unit mounting frame 21, and the input connector 31 and output connector 32 of the rectifier unit 11 can be smoothly connected to the connector receiving portion 31a of the input board 31 and the connector receiving portion 32a of the output board 32.

[0076] According to this embodiment, as shown in Figure 3, a first hole 41a provided in the input-side substrate 41 is inserted into a first support column 21a formed on the outside of the unit mounting frame 21, and the upper surface 21d of the first support column 21a is fixed with a first spacer 22, thereby forming a first gap 51 between the side surface 21e of the first support column 21a and the inner surface 41b of the first hole 41a, and a second gap 52 perpendicular to the back surface 41c of the input-side substrate 41 is formed between the bottom 21b of the first support column 21a and the back surface 41c of the input-side substrate 41. The second support column, second hole, and second spacer formed on the outside of the unit mounting frame 21 have a similar structure, so the fourth gap and the fifth gap are also formed in the same way. The first gap 51 and the fourth gap allow the input-side board 41 and the output-side board 42 to float and shift parallel to the board surface, and the second gap 52 and the fifth gap allow the input-side board 41 and the output-side board 42 to float and shift perpendicular to the board surface. Furthermore, by allowing the input-side board 41 and the output-side board 42 to float and shift simultaneously parallel and perpendicular to the board surface, it becomes possible for the input-side board 41 and the output-side board 42 to float and shift diagonally as well. As a result, when the rectifier unit 11 is inserted into the unit mounting frame 21, the input-side connector 31 is connected to the input-side connector receiving portion 31a, and the output-side connector 32 is connected to the output-side connector receiving portion 32a, the positional misalignment between the connectors due to assembly tolerances on the rectifier unit 11 side and the unit mounting frame 21 side can be absorbed by the floating function described above. Therefore, the risk of damage such as breakage of the power supply pins can be prevented, the rectifier unit can be inserted and removed smoothly, and the rectifier unit 11 can be easily replaced.

[0077] Furthermore, according to this embodiment, when the rectifier unit 11 is inserted into the unit mounting frame 21, the first guide pin 61 shown in Figure 1 is inserted into the first guide pin insertion port 62 shown in Figure 3, thereby aligning the position of the input-side connector 31 with the position of the input-side connector receiving portion 31a. This prevents the risk of damage such as breakage of the power supply pins when the input-side connector 31 is connected to the input-side connector receiving portion 31a and the output-side connector 32 is connected to the output-side connector receiving portion 32a, enabling smooth insertion and removal of the rectifier unit and making it easier to replace the rectifier unit 11.

[0078] Furthermore, it is also possible to implement the first and second embodiments described above by combining them as appropriate. [Explanation of Symbols]
