摘要:
A wafer connector for connecting cables to a pin header has a connector body portion that incorporates a strain relief member applied to the cables as part of the connector body portion. The strain relief member includes a cable clamp having a series of grooves that are separated by intervening land portions. The grooves receive the cables and space them in a particular spacing. The leads of the cable are terminated to corresponding tail portions of contacts of the connector. These tail portions are maintained in the same plane to enhance the electrical performance of the connector. An insulative material is molded over the tail portions and the cable clamp to form a connector with a cable clamp formed integrally with the body of the connector.

A cable assembly including a cable with at least one connector terminated to an end of the cable. The cable includes at least one pair of signal wires and a grounding member that extends the length of the cable. The signal wires and grounding member are terminated to a connector and specifically terminated to two signal terminals and one ground terminal of the connector. These wires are terminated to tail portions of the terminals which are enclosed in an insulative material that defines a body portion of the connector housing. The ground terminal has two contact portions that extend along the exterior of the connector housing body portion, while the signal terminals have contact portions that extend lengthwise of the connector housing. The signal terminal contact portions are enclosed within an extension of the connector housing and the extension and body portions are themselves enclosed in a metal grounding shell. The grounding shell engages the ground contacts at one end and has two contact arms integrally formed therewith that extend into the interior of the connector housing between the signal terminal contact portions.

An electrical connector assembly includes a first connector having a guide hole in a mating face thereof. A second connector includes a guide pin for insertion into the guide hole of the first connector, the guide pin having a latch portion. A latch member on the first connector engages the latch portion of the guide pin of the second connector when the connectors are mated to hold the connectors in mated condition. Therefore, the guide pin performs a dual function of guiding the connectors as well as latching the connectors.

A wearable portable speaker system for mobile electronic devices having at least one speaker capable of connecting to a mobile electronic device and a fixture for housing the at least one speaker. The fixture is formed as a collar having an opening formed therein and the at least one speaker is housed in the fixture so that an output of the speakers is at least partially directed upwards from a top portion of the fixture.
摘要:
A lighting device and system having at least one circuit, the circuit having at least two LEDs connected in series, parallel or anti-parallel configuration and at least one current limiting diode. The device or system may be driven with AC or DC power and may further include a sensor and polarity switching circuit to utilize all LEDs within the circuit when drive by DC power.

A telephone service provider or alarm company, supplies phone-line-power for auxiliary, backup, and/or emergency lighting in residential, commercial and/or industrial facilities at a reasonable charge in exchange for providing, maintaining and ensuring that lighting service and power will be available when needed such as under power failure situations. A phone-line-driven lighting device includes a sensor capable of detecting a primary power source. Once the sensor senses that the primary power source is not present, circuitry connects the device's phone line terminal to a light producing element, in turn powering the light producing element via a telephone line's DC or AC power. Such a device may include a control circuit which responds to a predetermined phone line signal, thereby controlling the operational state of the device. Such a signal could be broadcast in emergency or other informative situation by the provider of the phone line service.
摘要:
An AC LED package and circuits are disclosed along with an AC LED driver. The AC LED circuit may include as few as one LED or an array of anti-parallel LEDs driven with AC power sources and AC LED drivers at various voltages and frequencies. The AC LEDs are pre-packaged in various forms and materials and designed for mains or high frequency coupling in various forms to AC power sources, inverter type drivers or packages. The AC LED driver is a fixed frequency driver that provides a relatively constant voltage output to different size loads within the wattage limitation of the driver and in some cases is a direct mains power source.
