A USB (Universal Serial Bus) extension cord includes a connection cable, a male connector base, and a plurality of female connector housings. The male connector base is provided at one end of the connection cable, and the female connector housings are provided elsewhere on the connection cable at intervals. The male connector base is provided with a male USB connector, and each female connector housing is formed with at least one female USB connector. As each two adjacent female connector housings can be brought as far away from, and as close to, each other as the connection cable allows, the female connector housings can be easily arranged at appropriate positions in an environment to facilitate the use of low-voltage electricity.

An apparatus for inserting and retention testing an electrically conductive contact in an electrical connector. The apparatus includes a connector holder, an insertion tip, an insertion tip displacement assembly, a test probe, and a test probe displacement assembly. The connector holder holds an electrical connector. The insertion tip contacts one end of a contact partially inserted in a hole in the electrical connector while providing clearance for a wire. The insertion tip displacement assembly displaces the insertion tip in a first direction along a first linear path to further insert the insertion tip in the hole in the electrical connector. The test probe contacts another end of the contact after the contact has been inserted further into the hole. The test probe displacement assembly displaces the test probe in a second direction (opposite to the first direction) along a second linear path which partially overlaps the first linear path.

An electrical device coupling adapter that is operable to electrically connect an electrically operated device exteriorly located to a structure with a low voltage power source or a alternating current power source located within the interior of the structure. The present invention includes a housing being comprised of a base plate and a case portion wherein the case portion is removably secured to one side of the base plate. A first conduit member is secured to the case portion of the housing and is manufactured from a flexible tubing material. A second conduit member is sealably coupled to the base plate opposite the case portion. The second conduit member is rigid and tubular in form and extends outward from the base plate. A supply wire is secured within the second conduit member and can be configured to electrically coupled to either a AC or DC power source.

A pre-distorted electrical excitation signal is generated for an acoustic transducer having an armature and a non-linear transfer characteristic by applying an electrical input signal (x) representative of a desired acoustic output to a computable non-linear function that is a function of the electrical input signal (x). When applied to an input of the transducer, the pre-distorted electrical excitation signal results in an improved acoustic output signal.

An electrical connector for electrically connecting at least two electrical conductors featuring first and second electrical cables. The connector features at least one first conductor plate allocated to the first cable and at least one second conductor plate allocated to the second cable. Each conductor plate features in total a number of conducting structures with first contact sections which corresponds to at least the number of the conductors for electrical contacting of the allocated conductors and also second contact sections. Furthermore, the connector features a number of coupling elements corresponding to the number of conductors which are designed for electrically contacting the second contact sections of the respective conductor plate allocated to the respective conductor by bridging of a spatial gap between the first and second conductor plate.

A splice connector assembly includes a housing and a flat bus plate. The housing has openings on opposed end walls defining an axis being generally perpendicular to the opposed end walls. The flat bus plate is disposed within the housing, including a connecting strip extending generally perpendicular to the axis, a first set of male terminals extending outwardly from the connecting strip generally parallel to the axis, and a second set of male terminals extending outward from the connecting strip generally parallel to the axis and in an opposite direction from the first set of male terminals, wherein a free end of each of the male terminals are configured to receive and electrically connect with female flat terminals, and wherein the female flat terminals extend into the housing to connect to the male terminals through the openings on the opposed end walls.
