Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to high-voltage wiring components such as lamp sockets and terminal blocks for HID lighting equipment.

[0002]

2. Description of the Related Art A conventional example is shown in FIGS. That is, the lamp socket of this HID luminaire has an inverted U shape composed of a pair of side plates 50 and a central plate 51, and has a lamp pin insertion hole portion 52 in the central portion of the central plate 51 and a side plate of the lamp pin insertion hole portion 52. A conductive spring 54 having a recess 53 for the lamp pin guide at the edge of the side 50 and a recess 55 for accommodating the conductive spring 54 are provided at both ends 56 of the side plate 50.
And a support 57 for holding Lamp pin 58
Is inserted through the lamp pin insertion hole portion 52, and at this time, the lamp pin guide concave portion 53 is elastically deformed outward and elastically holds the lamp pin 58. 59 is a wire connection part, 60
Is an electric wire.

FIG. 14 shows another conventional example in which the conductive spring 54 has a U-shape, and has lamp pin guide recesses 53 on both side edges.

[0004]

However, this high-voltage wiring component has a mounting plate 60 which is grounded as shown in FIG.
When it is used by being attached to, the dielectric strength between the conductive spring 54 and the mounting plate 60 is determined by (Δd ₁ + d + Δd ₂ ). Here, Δd ₁ is a minute gap between the conductive spring 54 and the support 57, Δd ₂ is a minute gap between the mounting plate 60 and the support 57, and d is the thickness of the support 57, which is a general electric device such as a lighting fixture. Considering the normal withstand voltage performance of the applied voltage, the dielectric strength of resin insulation such as PBT and nylon is 10
It is about 30 kV / mm, and it is considered that there is no risk of dielectric breakdown by setting d to several mm. However, for example, like a starting pulse of an HID lamp, several kV to several tens of k
When a voltage of V is applied to the conductive spring 54, Δd ₁ and Δd ₂
Partial discharge may occur in the very small gap of the gas, which generates ozone or NOx (nitrogen oxide) gas,
This will corrode the conductive spring 54 and the support 57. Even if the side plate 50 is in close contact with the recess 55 at Δd ₁ = 0, since the conductive spring 54 is a thin plate and its tip is sharp, there is a risk of dielectric breakdown of the support 57 due to treeing. If such a problem is to be solved by increasing the thickness d of the support 57 and increasing the distance, the support 57 becomes high and is not practical.

Therefore, an object of the present invention is to provide a high-voltage wiring component having excellent insulation performance capable of suppressing partial discharge without increasing the size.

[0006]

According to a first aspect of the present invention, there is provided a high voltage wiring part having an inverted U-shape composed of a pair of side plates and a central plate, the central part of the central plate having a lamp pin insertion hole. A conductive spring having a recess for a lamp pin guide at the edge of the side plate of the insertion hole, and a support base inserted between the pair of side plates to support both ends of the center plate are provided. The supporting member is formed to have a length higher than the height of the side plate so that partial discharge can be suppressed, and a pressing member for pressing the central plate.

According to a second aspect of the present invention, there is provided a high-voltage wiring component, which has a support base having a predetermined height and a receiving portion mounted on an upper surface of the support base, and supports the side surface of the support base from the receiving portion. A conductive spring to which a high voltage is applied, which has a hanging part that hangs shorter than a height of a table so that partial discharge can be suppressed, and a recess for lamp pin guide is formed in a connecting part between the receiving part and the hanging part; And a pressing member for pressing and fixing the receiving portion.

A high-voltage wiring component according to a third aspect of the present invention has a conductive mounting plate having a plurality of mounting holes and an insulative body having a conductive portion provided therein. A main body having an insulating support leg that is in contact with the surface of the mounting plate, and an insulating lock leg that is hanging from the body and that has a locking claw at the tip that locks the retaining hole in the mounting hole. It is a thing.

[0009]

According to the high-voltage wiring component of the first aspect, when the lamp pin is inserted, the side plate is elastically deformed by being guided by the lamp pin guide recess of the side plate, and the lamp pin is sandwiched between the side plates. In this case, since the height of the support base is set higher than the height of the side plate so that partial discharge can be suppressed, the size can be reduced and the gap between the lower end of the side plate and the root of the support base can support the partial discharge and treeing. Insulation deterioration of the body can be prevented and the insulation performance of the support can be improved. Further, since the lamp pin insertion hole is formed at the center of the central plate supported by the support base, the lamp pin guide recess is accurately positioned with respect to the lamp pin. Further, since the support base is supported so as to cover the conductive spring, the conductive spring can be easily fitted into the support base and the assembling can be facilitated.

According to the high-voltage wiring component of the second aspect, the support portion supports the receiving portion of the conductive spring, the hanging portion is hung from the receiving portion on the side surface of the supporting base, and the connecting portion between the receiving portion and the hanging portion is formed. In addition to forming a recess for lamp pin guide in the, the height of the support base that can suppress partial discharge is higher than the height of the hanging part,
In addition to the same effect as in claim 1, the material used for the conductive spring can be reduced, so that downsizing and cost reduction can be achieved.

According to the third aspect of the high-voltage wiring component, when the locking claw of the locking leg of the main body having the conductive portion is inserted into the mounting hole, the locking claw is retained in the mounting hole and locked. The support legs abut the mounting plate to support the main body on the mounting plate. In this case, since the main body secures the insulation distance to the mounting plate by the length of the support leg, the main body can be downsized and the potential gradient can be reduced to prevent partial discharge. Furthermore, since the main body can be attached to the attachment plate with a single touch, the ease of assembly of the device is improved.
