Description

{CONNECTING UNIT, BUSDUCT CONNECTING DEVICE AND BUSDUCT SYSTEM HAVING THE SAME}

The present invention relates to a connecting unit, a bus duct connecting device, and a bus duct system having the same. More specifically, the present invention relates to a connecting unit, a bus duct connecting device, and a bus duct system having the same, which can connect a pair of bus ducts so that the bus bars constituting each bus duct are in a predetermined direction, for example, a right angle direction, when connecting a pair of bus ducts, and which facilitates the manufacturing process of the bus duct connecting device or the process of connecting a bus duct using the bus duct connecting device.

In the past, the method of wiring using wire cables was widely adopted as the method of power distribution, but recently, due to the rapid increase in the demand for electricity in buildings such as high-rise buildings, apartments, and large-scale factories, wiring using bus ducts using bus bars is spreading.

Bus ducts are equipped with bus bars that perform the same role as conductor cores included in cables and can transmit large amounts of current. Originally, for internal wiring in large buildings or large factories, bus duct wiring is superior to power cable wiring in terms of space utilization and ease of installation. Not only is this bus duct easy to expand and relocate, but it is also easy to handle and quickly recover in the event of an abnormality or accident in the bus bar power wiring, so it is widely used in places that use relatively large amounts of electricity.

The demand for bus duct systems that replace these power cables is rapidly increasing due to their advantages, such as large-capacity current transmission, efficient space utilization, ease of construction, and stable power quality. As competition among products intensifies, the competitive landscape is being formed toward lightweight, compact products in response to customer and market demands for diversity.

For the purpose of weight reduction and compactness, sandwich-type bus ducts that stack bus bars to form the bus duct are widely used. Such bus ducts are connected through connection kits at regular intervals depending on the shape or size of the space in which they are installed, and the bus bars at the end of the bus duct can be inserted into the connection kit in an exposed state so that they can be installed.

A typical bus duct connection kit is structured so that a current-carrying plate is provided on both sides of the connection space where the bus bars constituting the bus duct are inserted and electrically connected, and one bus bar is inserted into each connection space to connect.

FIG. 1 and FIG. 2 illustrate a state in which a general bus duct (100a) and a connection kit (200) for longitudinally connecting a bus duct (100b) are separated, and FIG. 2 illustrates an enlarged view of a state in which the bus duct (100a, 100b) and the connection kit (200) illustrated in FIG. 1 are connected.

As shown in FIG. 1 and FIG. 2, bus ducts (100a, 100b) for power supply are manufactured by unit length and can be connected via a connection kit (200). Accordingly, the bus ducts (100a, 100b) have a structure that can be connected to the connection kit (200) at both ends.

The bus duct (100a, 100b) illustrated in FIGS. 1 and 2 may be configured to include an outer case (30) that accommodates a plurality of bus bars (20) arranged in parallel or stacked, a male connection part (40) formed by exposing a conductor (21) while the bus bars (20) are spaced apart at at least one end in the longitudinal direction of the outer case (30), a pair of additional plate members (50) that are fastened to an end of the outer case (30) and arranged parallel to the bus bars (20) on the outside of the male connection part (40), a mold member (60) that is fastened to an end side of the outer case (30) and provides a mounting surface for the additional plate member (50).

The busbars (20) of the above bus ducts (100a, 100b) can be arranged so as to be stacked in a sandwich manner, i.e., in contact with each other. That is, the plurality of busbars (20) can be accommodated in the outer case (30) in a state in which a plurality of them are stacked adjacent to each other.

The above busbar (20) may be made of a conductor (21) such as copper or aluminum. The surfaces of the conductors (21) are each coated with an insulator (23) such as an epoxy coating, and are mutually insulated even when laminated. Since the busbar (20) typically carries a large current, it is first coated with an insulator (21) to insulate it, and is housed inside the outer case (30) in a state of isolation from the outside to protect it.

These bus ducts (100) can be connected at predetermined intervals by means of a connection kit (200) to increase the power transmission length.

That is, a pair of bus ducts (100a, 100b) can be connected to each other in a straight direction by a connection kit (200) as shown in FIGS. 1 and 2, so that their lengths can be extended.

The above connection kit (200) is provided with a conductive plate (not shown) into which the busbars (20) of each bus duct (100) are inserted and electrically connected, so that the busbars (20) of each phase are mutually insulated and electrically connected, and can be used as a connection means for connecting the bus ducts (100).

However, this general connection kit (200) is a means for connecting the bus duct (100) in its longitudinal direction, and cannot be used as a connection means for changing the direction of the bus duct (100) in a orthogonal or perpendicular direction other than the longitudinal direction.

Figure 3 shows an example of a conventionally used bending bus duct.

In the past, in order to change the connection direction of the bus duct, a pair of bus ducts (100a, 100b) were each cut diagonally along the outer case (30) and the bus bar (20), and the cut portion was welded to form a vertical bend portion (a), thereby forming a single bent bus duct.

Accordingly, in places where it is necessary to change the connection direction of the bus duct, the folded bus duct manufactured as described above was applied, but the process of manufacturing one folded bus duct requires cutting and welding of the bus duct (100a, 100b), so the manufacturing process is complicated and expensive. In addition, in the process of installing the folded bus duct in places where it is necessary to change the connection direction of the bus duct, the size and weight of the folded bus duct itself are large, so there was a problem that workability was low.

The present invention aims to solve the problem of providing a connection unit, a bus duct connection device, and a bus duct system having the same, which can connect a pair of bus ducts so that the bus bars constituting each bus duct are in a predetermined direction, for example, a right angle direction, and which facilitates the manufacturing process of the bus duct connection device or the process of connecting the bus duct using the bus duct connection device.

In order to solve the above problem, the present invention comprises: a pair of connection kits, each of which has a pair of bus ducts having a plurality of bus bars connected to one side thereof, and having a plurality of current-carrying plates and a plurality of insulating plates; a plurality of insulating plates connected to the layered insulating plates of the connection kit; a plurality of connecting conductors each interposed between the plurality of insulating plates, each of which is connected to the current-carrying plates of the respective connection kits, and each of which is bent at least once at a predetermined angle; a pair of cover members each of which is provided on the outer side of an outermost insulating plate among the plurality of insulating plates; and a connecting bolt that penetrates and connects the insulating plates, the connecting conductors, and the cover members; and a connecting unit that connects the pair of connection kits and connects them, and can provide a bus duct connecting device for connecting the bus bars constituting the pair of bus ducts at a predetermined angle.

In addition, the plurality of insulating plates, the plurality of connecting conductors and the plurality of covering members constituting the connecting unit are bent by 90 degrees so as to connect the busbars constituting the pair of bus ducts at right angles.

In this case, the insulating plate, the connecting conductor and the covering member can be folded twice.

And, the insulating plate, the connecting conductor, and the covering member are each folded twice to be divided into a fastening area in the center and connecting areas on both sides of the fastening area, and the fastening bolt can penetrate the center of the fastening area.

Here, the plurality of connecting conductors can be inserted into the layered connecting spaces of the connecting kit and connected in such a way that the upper or lower surface comes into surface contact with the conducting plate.

In addition, a spacer may be provided between the insulating plate, the connecting conductor, and the cover member, each of which is inserted through the fastening bolt.

In addition, among the adjacent insulating plates, the connecting conductor and the covering member, the length of the covering member may be the longest and the length of the insulating plate in the bus duct connection direction may be the shortest.

In this case, a plastic fastening clip may be included that clamps and fixes the side end of the insulating plate and the side end of the insulating plate of the connecting kit in both directions.

Additionally, the fastening clip may have an insertion slot in the opposite direction.

Here, in a state where the connection kit and the connection unit are assembled, a plurality of fixing projections or fixing grooves may be provided on one surface of each of the surfaces of the conductive plate of the connection kit and the connection conductor of the connection unit that are in surface contact with each other, and a fixing groove or fixing projection may be provided on the other surface to which the plurality of fixing projections or fixing grooves are formed and fixed.

In addition, the plurality of fixing projections or anchoring grooves may be provided spaced apart in the width direction of the current-carrying plate of the connecting kit and the connecting conductor of the connecting unit, respectively.

In addition, in order to solve the above problem, the present invention can provide a bus duct system including the above-described bus duct connecting device; and a pair of bus ducts each connected to a pair of connecting kits constituting the bus duct connecting device.

In this case, an insulated busbar may be configured by stacking it inside the outer case forming the pair of bus ducts.

In addition, in order to solve the above problem, the present invention can provide a connection unit including a pair of bus ducts having a plurality of bus bars, each connected to one side thereof, and a pair of connection kits having a plurality of current-conducting plates and a plurality of insulating plates, each connected, wherein the connection unit comprises: a plurality of insulating plates connected to the layered insulating plates of the connection kit; a plurality of connecting conductors each interposed between the plurality of insulating plates, each connected to the current-conducting plates of the respective connection kits, and bent at least once at a predetermined angle; a pair of cover members each provided on the outer side of an outermost insulating plate among the plurality of insulating plates; and a connecting bolt that penetrates and connects the insulating plates, the connecting conductors, and the cover members.

According to the connecting unit, bus duct connecting device and bus duct system having the same according to the present invention, when connecting a pair of bus ducts, the bus bars constituting each bus duct can connect the pair of bus ducts in a predetermined direction, for example, in a right angle direction, and the manufacturing process of the bus duct connecting device or the bus duct connecting process using the bus duct connecting device can be facilitated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosed contents can be thorough and complete, and so that the spirit of the present invention can be sufficiently conveyed to those skilled in the art. Like reference numerals represent like elements throughout the specification.

FIG. 4 is a perspective view illustrating a process of connecting a pair of bus ducts (100a, 100b) in a bus duct system (1000) according to the present invention, and FIG. 5 illustrates a state in which a bus duct connection device (1) of FIG. 4 and a pair of bus ducts (100a, 100b) are connected to complete the bus duct system (1000).

The bus duct connection device (1) according to the present invention is a device that connects two bus ducts (100a, 100b) at a predetermined angle.

The embodiments illustrated in FIGS. 4 and 5 illustrate examples in which the busbars (20) constituting the busducts (100a, 100b) are connected in a right angle (90 degrees of the angle of intersection of the extension planes). However, this is not limited thereto, and the angle of intersection of the extension planes may be applied in various ways (for example, 70 degrees or 110 degrees).

Here, in the embodiments shown in FIGS. 4 and 5, the fact that the busbars (20) are connected in a right-angled direction means that each of the busbars to be connected is arranged on a different plane, but each extension plane is connected so as to be orthogonal.

The bus duct connection device (1) according to the present invention may be configured to include two connection kits (200a, 200b) and one connection unit (300). The pair of connection kits (200a, 200b) are originally a connection means for connecting a general bus duct in the middle to connect the bus duct in a straight direction, but in the present invention, one pair may function as a means for enabling a right-angled connection of the bus duct in a state where it is connected to both sides of the connection unit (300).

In the present invention, the connection unit (300) is mounted between the pair of connection kits (200), and the male connection part (40) provided at the end of each bus duct (100) in the connection direction can be mounted on the pair of connection kits (200). As described above, in the past, in order to connect the bus ducts (100a, 100b) in a right-angled direction, a method of cutting and welding the bus ducts (100a, 100b) in a diagonal direction was used, but the present invention has a structure that can be connected or mounted in an assembly manner without requiring a process such as welding, unlike the conventional right-angled connection structure, by employing the connection unit (300).

The above connection unit (300) may have a structure in which it is inserted, connected, and fastened to the connection kit in the same way as the method of connecting the bus duct (100a, 100b) to the connection kit (200).

As shown in FIGS. 4 and 5, when connecting two bus ducts in a right-angled direction, the male connection part (40) of the bus duct (100a, 100b) can be inserted and mounted on one side of each of a pair of connection kits (200) constituting the assembled bus duct connection device (1), thereby connecting the bus ducts in a right-angled direction.

Therefore, the bus duct connection device (1) of the present invention can connect the bus duct (100a, 100b) at a right angle by mounting it on the connection kit (200) assembled with the connection unit (300) without a separate cutting or welding process at the connection site and tightening the bolt (240, see FIG. 7) of the connection kit (200), thereby simplifying the on-site work. The connection unit (300) will be described with reference to FIG. 6 and below.

FIG. 6 is an exploded perspective view of a connection unit (300) of the present invention, FIG. 7 is a side view of the connection unit (300) and one connection kit (200) connected, and FIG. 8 is a cross-sectional view of the connection unit (300) and connection kit (200) of the present invention shown in FIG. 7 connected.

The present invention relates to a connection unit in which a pair of bus ducts (100a, 100b) each having a plurality of bus bars are connected to one side thereof, and a pair of connection kits (200a, 200b) each having a plurality of current-carrying plates and a plurality of insulating plates are connected, the connection unit comprising: a plurality of insulating plates (320) connected to the layered insulating plates (220) of the connection kits (200); a plurality of connection conductors (310) each interposed between the plurality of insulating plates (320), connected to the current-carrying plates (210) of the respective connection kits (200), and bent at least once at a predetermined angle; a pair of cover members (380) each provided on the outermost insulating plate among the plurality of insulating plates (320) and inserted into the upper and lower cover plates (280) of the respective connection kits (200); And a connecting unit (300) including a connecting bolt (340) that penetrates and connects the insulating plate (320), the connecting conductor (310), and the cover member (380) can be provided.

The above connecting unit (300) may be provided with a cover member (380) on the outermost side, and may be provided with a plurality of insulating plates (320) and a plurality of connecting conductors (310) therebetween. In addition, in order to connect the bus duct (100) at a predetermined angle, each of the insulating plates (320), the connecting conductors (310), and the cover member (380) constituting the connecting unit (300) of the present invention may have a structure in which they are bent at a predetermined angle.

In the embodiment of the present invention illustrated in FIG. 4 and below, an example is shown in which the busbars (20) constituting the busduct (100a, 100b) are connected at right angles, but the angle is not limited, and the meaning that the busbars (20) are connected at right angles means that a pair of busbars connected to the two busducts through the busduct connecting device (1) are arranged on different planes, but their longitudinal extension planes intersect each other at right angles, as described above.

In this specification, the structure of the connecting unit (300) for allowing the busbars (20) constituting the two bus ducts (100a, 100b) to be connected at right angles is examined.

The above connecting unit (300) may be provided with a cover member (380) on the outermost side, and may have a plurality of insulating plates (320) and a plurality of connecting conductors (310) provided therebetween. In addition, in order to connect the bus duct (100) in a right-angled direction, each of the insulating plates (320), the connecting conductors (310), and the cover member (380) constituting the connecting unit (300) of the present invention may be bent two or more times to extend in a right-angled or vertical direction.

In the embodiment illustrated in FIG. 6, the insulating plate (320), the connecting conductor (310), and the cover member (380) are each bent twice and extended in a right-angled direction. The insulating plate (320), the connecting conductor (310), and the cover member (380) may be bent once or three or more times, or may be bent into a curved shape. However, it is preferable that the fastening area be configured as a plane in order to be fastened by a fastening bolt (340) or the like while interposing a spacer (326), and therefore the insulating plate (320), the connecting conductor (310), and the cover member (380) may be each bent twice in the same direction (45 degrees or 135 degrees) to divide the fastening area in the center into a fastening area and connecting areas on both sides of the fastening area. The fastening bolt (340) may be fastened by penetrating the center of the fastening area.

As illustrated in FIG. 6, the bending direction and the bending angle (θ) at the bending portions of the insulating plate (320), the connecting conductor (310), and the cover member (380) are the same at 45 degrees or 135 degrees, but the width of the fastening region (w2) and the width of the connecting region (w1, w3) gradually increase from the inner to the outer side among the insulating plate (320), the connecting conductor (310), and the cover member (380), so that both ends of each of the insulating plate (320), the connecting conductor (310), and the cover member (380) can extend to the same point.

The present invention comprises a connection unit (300) to enable busbars constituting a bus duct (100) to be connected in a right-angled direction, and the connection unit (300) comprises a plurality of connection conductors (310) to connect a plurality of busbars (20) of both bus ducts (100) in a right-angled direction. The connection conductors (310) may be made of copper, aluminum or an alloy thereof having good electrical conductivity.

When the above connection kit (200) is connected to the bus duct (100), the bus bar (20) constituting the bus duct (100) and the conductive plate (210) of the connection kit (200) are in surface contact while being laminated to form a current path.

The above connecting conductor (310) and the cover member (380) may be composed of a metal material, and the insulating plate (320) may be composed of a resin material such as plastic.

In addition, the insulating plate (320), the connecting conductor (310) and the cover member (380) can be connected by penetrating with a single connecting bolt (340), and a spacer (326) that penetrates and is interposed through the connecting bolt (340) between the insulating plate (320), the connecting conductor (310) and the cover member (380) can be configured so that the insulating plate (320), the connecting conductor (310) and the cover member (380) that are laminated can be spaced apart from each other.

An insulating plate (320) for insulating each of the above-described plurality of connecting conductors (310) can be fixed or connected to the insulating plate (220) of the connecting kit (200).

The above insulating plate (320) may be composed of a resin material such as plastic, and unlike the connecting conductor (310), the insulating plate (320) does not need to be in surface contact with the insulating plate (220) of the connection kit (200) and the insulating surface may be expanded. Accordingly, the length of the insulating plate (320) in the bus duct connection direction may be the shortest.

Accordingly, the plurality of insulating plates (320) can be connected side by side with each insulating plate (220) of the connection kit (200), and the connection unit (300) of the present invention can be configured to include a fastening clip (330) made of a resin material such as plastic that clamps and fixes the side end of the insulating plate (320) and the side end of the insulating plate (220) of the connection kit (200) in both directions.

The above fastening clip (330) may be provided with an insertion slot of a shape symmetrical in the opposite direction. That is, the insertion slot of the above fastening clip (330) is configured in a bidirectional shape, such as a “c” or “ㄷ” shape, so that the side-facing end of the insulating plate (320) and the side-facing end of the insulating plate (220) of the connection kit (200) can be inserted and fixed, respectively.

And, the connecting conductor (310) of the connecting unit (300) and the current plate (210) of the connecting kit (200) that constitute the connecting unit, the bus duct connecting device and the bus duct system (1000) equipped therewith according to the present invention can be maintained in a surface contact state by the fastening force of each fastening bolt (240, 340), but if the fastening force of the fastening bolt is weakened or the fastening bolt is loosened after the installation process, rotation, twisting or separation may occur in one of the connected connecting kit (200) and the connecting unit (300).

Therefore, the connection unit, bus duct connection device and bus duct system (1000) equipped therewith according to the present invention can form a plurality of fixing protrusions or fixing grooves on the surface of the connection conductor (310) of the connection unit (300) and the current-carrying plate (210) of the connection kit (200) in order to prevent rotation, twisting or separation of one of the connection kit (200) and the connection unit (300).

By providing a positioning function in such a way that a fixing projection or a fixing groove of a mutually compatible shape is provided and the fixing projection (p) is fixed in the fixing groove of a corresponding position in the connected state of the connection unit and the connection kit, rotation, twisting or separation of the connection kit (200) and the connection unit (300) can be alleviated or prevented.

In addition, since the above-mentioned fixing projections or anchoring grooves, etc., may be easily damaged or deformed when provided on an insulating plate or insulating plate made of a resin material such as plastic, it is preferable that they be provided on a connecting conductor and a current-carrying plate in which a metal material is in surface contact.

In the case of each connecting conductor (310) illustrated in FIG. 6, two fixing projections (p) and/or fixing grooves (g) are provided in the area connected to each connecting kit, and it is preferable that at least two or more of each fixing projection or fixing groove are provided in the width direction (direction perpendicular to the connecting direction) on the surface of the connecting conductor (310) of the connecting unit (300) and the current-carrying plate (210) of the connecting kit (200) in order to stably support the connection state of the connecting kit (200) and the connecting unit (300).

And, as illustrated in FIG. 6, the fixing projections (p) or anchoring grooves (g) provided in the width direction of each connecting conductor (310) may be configured in a mixed manner, and in this case, the fixing projections (p) or anchoring grooves (g) corresponding to the anchoring grooves or anchoring projections may be formed on the current-carrying plate of the connection kit (200).

In addition, if the conductive area of the connecting conductor and the conductive plate is sufficient, the structure for each fixing projection (p) to be secured may be configured in the form of a hole rather than a groove.

In the embodiment illustrated in FIG. 6, it is illustrated that all connecting conductors (310) are provided with fixing projections (p) or anchoring grooves (g), but even if fixing projections (p) or anchoring grooves (g) are formed only on some connecting conductors (310), rotation, twisting, or separation of one of the connecting kit (200) and the connecting unit (300) can be alleviated or prevented.

The connection kit (200) illustrated in Fig. 7 is a connection means for connecting a bus duct in its longitudinal direction, but each connection kit (200) constituting the bus duct connection device (1) of the present invention may have a bus duct (100) mounted on one side or in one direction, and a connection unit (300) mounted on the other side or in the other direction.

In FIGS. 7 and 8, each connection kit (200) and connection unit (300) is depicted as having three connection spaces or conductors for connecting a three-phase bus duct, but the number may be increased or decreased depending on the system.

The above connection kit (200) may include a plurality of insulating plates (220) that are provided in parallel and spaced apart from each other to insulate a plurality of phase-specific busbars (20) of a bus duct (100) and form connection spaces (S1, S2, and S3) of the busbars (20); a plurality of conductive plates (210) that are respectively provided in the connection spaces (S1, S2, and S3) so as to come into contact with the plurality of phase-specific busbars (20); a pair of cover plates (280) that are respectively provided on the outer side of the outermost insulation plate (220) among the insulating plates (220); and a fastening bolt (240) that connects the insulating plate (220), the conductive plate (210), and the cover plate (280) in a penetrating and stacked state.

A plate spring (250) is provided on the side where the above-mentioned fastening bolt (240) is inserted and on the other side where the fastening nut (270) is tightened, so that the fastening force can be strengthened.

Of course, the above-mentioned conductive plates (210) may be provided in total of six, with two in each connection space (S1, S2, and S3) so that they are in surface contact with both sides of the busbar (20) of the bus duct (100) or the connecting conductor (310) of the connecting unit (300), but in order to reduce weight and cost, as shown in FIGS. 7 and 8, three in total may be provided, with one in each connection space (S1, S2, and S3), so that one conductive plate (210) and one connecting conductor (310) are in surface contact.

And, in the embodiment illustrated in FIGS. 7 and 8, the bus duct is configured as three phases (n=3) and accordingly, the connection unit (300) is provided with three connection conductors and four insulating plates, but the number can be increased or decreased depending on the number of bus bars in the bus duct.

As shown in FIGS. 7 and 8, the conductive plate (210) provided in the connection kit (200) forms a structure in which it is mounted on each insulating plate (220) and forms a plurality of connection spaces (S1, S2, and S3) between the insulating plates (220) provided spaced apart from each other.

The above connection kit (200) may also be provided with a spacer (226) to form connection spaces (S1, S2 and S3) of the busbar (20) or the connecting conductor (310), similar to the above connection unit (300), and the cover plate (280), the insulating plate (220) and the conductive plate (210) may be connected through a single fastening bolt (240).

The plurality of connecting conductors (310) constituting the connecting unit (300) are inserted into the layered connecting spaces (S1, S2 and S3) of the connecting kit (200), so that the upper or lower surface can come into surface contact with the conducting plate (210) to increase the conducting area.

The cover member (380) constituting the outermost part of the above-mentioned connection unit (300) can be inserted up to the step (drawing symbol not shown) below the cover plate (280) of the above-mentioned connection kit (200) to provide a stopper function that limits the insertion depth of the connection unit (300) into the connection kit (200).

And, the insulating plate (320) of the above connecting unit (300) can be connected or fixed to the insulating plate (220) of the above connecting kit (200) via a fastening clip (330).

As described above, the above fastening clip (330) has insertion slots in both directions, so that the insulating plate (220) and the insulating plate (320) of the above connecting kit (200) can be inserted and fixed by a press-fit method, respectively.

And, the connecting conductor (310) constituting the connecting unit (300) can be electrically connected in a manner that it is inserted into each of the connecting spaces (S1, S2 and S3) of the connecting kit (200) and makes surface contact with the conductive plate (210) of the connecting kit (200). The method of connecting the connecting conductor (310) constituting the connecting unit (300) and the conductive plate (210) of the connecting kit (200) can be considered to correspond to the method of connecting each of the bus bars (20) constituting the bus duct (100).

In the embodiment illustrated in FIGS. 7 and 8, a mounting groove is formed on the upper surface of the insulating plate (220) constituting the connection kit (200) and each conductive plate (210) is mounted thereon, and the structure is illustrated such that it makes surface contact with the lower surface of the connecting conductor (310) of the connection unit (300) inserted into each of the connection spaces (S1, S2, and S3). However, the structure may also be such that the conductive plate (210) is mounted on the lower surface of the insulating plate (220) constituting the connection kit (200).
