  • Patent number: 10718504
    Abstract: A lamp holder for an LED string light includes a lamp housing, an LED lighting module, a plug, and a socket. An open end of the lamp housing is pre-sintered with an encapsulation layer. The LED lighting module is disposed in the lamp housing, and has a cathode pin and an anode pin extending out from the encapsulation layer. Because the LED lighting module is pre-encapsulated in the lamp housing, when installed, only the LED lighting module and the plug need to be assembled so as to complete the assembly of the lamp housing, the LED lighting module and the plug. This reduces the assembly steps for production.

  • Patent number: 7253556
    Abstract: A lamp for a light string has a mechanical shunt to allow current to pass to the next light in the event of a missing bulb. A resilient shunt is held in a generally lateral orientation by a shunt holder within the socket. When the hollow base with its bottom opening is inserted into the socket, the walls of the base cam the ends of the shunt away from the electrical contacts on the walls of the socket. Likewise, when the base is removed, the resilient lateral ends of the shunt return to engage the electrical contacts. The timing of the contact by the shunt with the electrical contacts avoids arcing. Additionally, slits formed in the wall of the base allows the Dumet wires to exit the sides of the base in the correct location for engaging the electrical contacts, thus reducing the instances of misaligned Dumet wires.

    Abstract: A dielectric connector for use in high voltage devices, including x-ray tubes, is disclosed. The connector comprises a dielectric material and is pre-formed before attachment to the x-ray tube. Pre-formation of the connector creates a first cavity portion therein that conforms in shape to a corresponding segment of the tube surface. A second cavity portion is also defined for receiving a high voltage receptacle. Upon attachment to the tube, the first cavity portion receives the corresponding tube segment. The high voltage receptacle is received into the second cavity portion and electrically connects with a receptacle defined on the tube surface. The receptacle enables a high voltage signal passing through the electrode to connect with either the anode or cathode disposed within the tube. Pre-formation of the connector enables connector testing and repair to occur before it is attached to the tube, saving resources, time, and cost.

  • Patent number: 6556654
    Abstract: A system for securely maintaining a high voltage cable within an electrical device, such as an x-ray tube, is disclosed. The system is useful for ensuring a close fit between an x-ray tube cathode insulator and the high voltage cable assembly disposed therein, thereby reducing the chances for damaging electrical arcing to occur. A high voltage cable assembly and clamp body generally comprise the system. The high voltage cable comprises two sections disposed at a right angle with respect to one another. One section defines a cavity for receiving a plunger/spring assembly housed within the clamp body. The plunger/spring assembly compresses and expands in response to the thermal expansion and contraction of the high voltage cable assembly during tube operation. A calibration window and adjustment screws are provided with the clamp body to enable a technician to readily determine and adjust the level of compressive force imparted by the system.

The glass plate (3) has at least one recess (4) in which a bridge (15) to a current conductor (12) is located, which bridge (15) has a disconnection (16) in the recess (4), thus insulating the relevant current conductor (12) from the metal member (10). The lamp is of a simple construction that can be easily realized. The current conductors (12) occupy a predetermined position with respect to one another in the lamp owing to the use of the shaped metal body (20), and fewer components have to be combined in the manufacture of the lamp.
