Description

A high-voltage insulating lamp holder

technical field

The utility model relates to a lamp holder, in particular to a matching xenon lamp lamp holder for a high-power xenon lamp light source, which belongs to the field of lighting equipment.

Background technique

Xenon lamp, also known as high intensity discharge lamp (High intensity Discharge), English abbreviation HID. Its main light-emitting principle is: after the power is turned on, a high-voltage pulse voltage of up to 20,000 volts will be provided instantly through the transformer, and then the xenon gas installed inside the bulb will be excited to produce a light with a color temperature of 6000K-10000K in the arc.

The purity of this light is close to daylight, and the acceptance and comfort of the human eye are the highest. Therefore, such lights are used in nighttime lighting of vehicles, which has the technical advantages of reducing the driver's visual fatigue and improving driving safety. Therefore, xenon Lamps have been widely promoted in the field of automotive lighting.

However, the lamp caps and lamp holders of many xenon lamps currently sold and used on the market follow the structure of the traditional metal halide lamp, and are not designed for the characteristics of xenon lamps. The creepage distance is less than 20MM, and can only withstand the pulse voltage below 7KV, and the pulse voltage of the xenon lamp generally needs to reach 23KV.

Therefore, when in use, the traditional xenon lamp is easy to ignite due to insufficient safe creepage distance, causing the positive and negative poles to ignite when starting, resulting in a short circuit, which in turn causes damage to the light source and ballast, which has great safety Hidden danger.

Utility model content

The utility model proposes aiming at the shortcoming of the low creepage distance of the existing xenon lamp, and provides a lamp cap of the xenon lamp with high creepage distance and good safety performance.

The technical solution adopted by the utility model to solve the problems of the technologies described above is as follows:

A high-voltage insulated lamp cap, comprising a body part and an upper surface part arranged on the body part, two insulating pin parts are arranged on the upper surface part, and conductive plugs are respectively arranged on the pin parts part, a groove part is formed on the upper surface part, and the groove part is located at the center of the two pin parts.

Further, in a preferred structure, the groove portion is a groove with an elongated shape.

Further, a preferred structure is that the conductive plug part is a cylindrical structure.

Further, a preferred structure is that the pin portion is a cylindrical structure.

Further, in a preferred structure, the length of the long side of the groove portion is greater than the diameter of the pin portion.

After the utility model adopts the above-mentioned technical scheme, since a groove portion is set between the conductive plug portions, after the groove portion is matched with the corresponding socket, the gap between the original two conductive plug portions can be reduced. The creepage distance of the straight line between them becomes the creepage distance of the curve around the groove, thus having a better safety control effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

Fig. 1 is a schematic structural view of the high-voltage insulating lamp cap of the present invention; Fig. 2 is a schematic cross-sectional view of the high-voltage insulating lamp cap of the present utility model.

As shown in Fig. 1 and Fig. 2, the high-voltage insulating lamp cap is mainly used in xenon lamps. As shown in the figure, the high-voltage insulated lamp cap includes a body part 301 and an upper surface part 303 provided on the body part 301, and two insulating pin parts 201 and 202 are arranged on the upper surface part 303. The pin portions 201 and 201 are provided with conductive plug portions 101 and 102 respectively, and the conductive plug portions 101 and 102 are respectively electrically connected to the lamp cap components (not shown in the figure) arranged below them.

The lamp holder with the above structure has been widely used in the prior art. Since the distance between the two conductive plug parts 101 and 102 is a straight line, the creepage distance thereof is relatively short, which poses a certain potential safety hazard.

To solve the above problem, as shown in FIG. 1 , a groove portion 302 is further provided on the upper surface portion 303 , and the groove portion 302 is located in the middle of the two pin portions 201 and 202 . Generally, it is preferred that the groove portion 302 is located approximately at its central position.

In a preferred embodiment, the conductive plug parts 101 and 102 and the pin parts 201 and 202 are all in the shape of a cylinder, of course, other shapes can also be selected for the two.

And, we preferably, described groove part 302 is a groove of elongated shape, and it comprises an elongated upper opening part, and, the length of the long side of described upper opening part is greater than described pin part The corresponding diameter lengths of 201 and 202.

Fig. 3 is a structural schematic diagram of a lamp holder matched with a high-voltage insulating lamp cap of the present invention.

As shown in the figure, the high-voltage insulated lamp holder includes a lamp holder body part and sockets provided on the lamp holder body part corresponding to the above-mentioned pin parts and conductive plug parts.

Furthermore, with respect to the above-mentioned groove portion, a bump baffle portion 403 whose size and shape match the groove portion is provided on the high voltage insulated lamp holder.

Through such a design, we change the original linear creepage distance between the two conductive plug parts into a curved creepage distance bypassing the groove, thus having a better safety control effect.

In addition, in a preferred embodiment, we increase the height of the pin portion, which can also significantly increase the creepage distance of the lamp cap.

After adopting the above technical scheme, the utility model can make the safe creepage distance reach 33MM, which is enough to withstand all pulse voltages below 25KV. It overcomes the potential safety hazards of 25KV pulse voltage, and has a better technical effect compared with the traditional structure.
