Cable winding devices and mechanisms for providing direct cable to electrical component connections without brush contacts are disclosed. Electronic controls may be provided directly on the cable winding device. The cable winding device generally includes two cable segments physically disconnected from each other, a spool configured for winding the cable segments thereon, and a circuit component such as a printed circuit board assembly that rotates with the spool. The circuit component may include electrical contacts to electronically connect corresponding pairs of wires of the cable segments and a user-adjustable or user-actuatable electronic control in communication with the electrical contacts. The circuit component may provide a pair of electrical contacts for each corresponding pair of wires in the cable segments and the electronic control is in communication with at least one pair of the electrical contacts. The cable segments form a continuous electrical path through a circuit component with electronic controls.
A wire winding device with transmission line is pulled at one end. The retaining end module and the telescopic end module are fixed together. The transmission line of the transmission line can be received in the spacing layer. In use only one end of the transmission line is pulled out. The transmission line will can be arranged orderly. The wire winding device has the function of adjusting the length of the earphone at any time without affecting the data reading or playing. Thereby the transmission line can be connected to various devices, such as earphones, USB connectors or signal connectors, to be connected to various electronic devices, such as computers, and mobile phones, etc. Thereby structure is simple and can be operated easily.
An electrical fixture consistent with certain embodiments has a light fixture and a mount used to attach the light fixture to a ceiling. An electrical outlet is electrically connected to a source of line voltage by an electrical cable. A retraction mechanism, dispenses and retracts the electrical cable, so that the electrical outlet can be moved between a retracted position adjacent the light fixture with the electrical cable fully retracted and at least one extended position wherein at least a portion of the electrical cable is dispensed from the retraction mechanism. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
