Abstract: An electronic device with an illuminated nameplate includes at least one light-emitting device, at least one circuit board, at least one casing and at least one opening. In this casing, at least one connector connects with the circuit board. The casing has at least one nameplate. The light emitted by the light-emitting device passes through at least one part of the nameplate. The opening is formed on the nameplate.

Abstract: An antenna adapter in accordance with the present invention comprises an elongate housing defining a receiving space and first and second ends opposite to each other. A first connector is fixedly positioned in the first end. A second connector is rotationally arranged in the second end and is electrically coupled to the first connector. A positioning device is arranged between the housing and the second connector such that the second connector can be angularly positioned with respect to the housing.

Abstract: A connector adapter that can be used to directly connect a peripheral device to a host device. The connector adapter is adjustable so as to allow selective reorientation of the peripheral with respect to the host device. The connector adapter includes a limiting mechanism that restricts the degree to which the adapter can be selectively rotated. In addition, the adapter includes an indexing mechanism that allows the position of the adapter to be locked in predetermined positions.

Abstract: A stacked electrical connector comprises triple stacked dielectric housings with a similar structure, a bottom, a middle and a top conductive terminal groups and two sets of transition contacts engaging with the middle and the top terminal groups, a one-piece grounding contact having three contacting arms inserting into the three stacked housings, a spacer and a conductive shield enclosing the stacked housings and the two sets of the transition contacts. The middle and the top terminal groups have a same structure, thereby simplifying the manufacture of the stacked electrical connector. An upper and a lower retaining blocks are prepared for fastening to the middle and the top housings. The spacer forms a pair of latching posts engaging with the lower retaining block for fixing the stacked housings against the spacer and defines a plurality of grooves to position the two sets of transition contacts.

Abstract: A receptacle electrical connector assembly of the present invention comprises a main frame, three electrical connectors, a first and a second side cover positioned on both sides of the electrical connector assembly, a first group of terminals, a second group of terminals, and a grounding terminal mounted on the first side cover and a third group terminal mounted on the second side cover, and a shield covering a front of the receptacle electrical connector assembly. The main frame defines three receiving cavities. Each electrical connector has a housing and a set of contacts retained in the housing which is designed to mate with an inserted audio jack. The contacts comprising a first contact, a second contact, a grounding contact, and a pair of switch contacts.

Abstract: A receptacle electrical connector assembly of the present invention comprises a main frame, three electrical connectors, a first and a second side cover positioned on both sides of the electrical connector assembly, a first group of terminals, a second group of terminals, and a grounding terminal mounted on the first side cover and a third group of terminals mounted on the second side cover, and a shield covering a front of the receptacle electrical connector assembly. The main frame defines three receiving cavities. Each electrical connector has a housing and a set of contacts retained in the housing which is designed to mate with an inserted audio jack. A plurality of contacting portions project from either side of the housing. A plurality of contacting portions of the grounding contacts project from a certain side of the housings, and the contacting portions of the contacts of the middle electrical connector projecting from the other side of associated housing.

Abstract: A switching device for an electrical connector comprises a cover and a base securely assembled with the cover. A plurality of contacts comprising first contacts, second contacts, and third contacts are secured in the base. A plurality of switching terminals each includes a positioning portion, a first tab, a second tab, and a third tab. Each switching terminal forms a pushing end opposite the positioning portion, the pushing end also connecting the first tab to the third tab. The tabs respectively form first, second, and third contacting portions thereon. In operation, the first and the second contacting portions are respectively engaged with the first and second contacts when the pushing end is not being pushed laterally. When the pushing end is pushed laterally, the first contacting portion disengages from the first contact, and the third contacting portion moves to engage with the third contact, thereby switching a signal transmission.

Abstract: A method for manufacturing an electrical connector having at least two rows of high density contacts, comprises steps of stamping and forming, depositing, insert molding, severing, and assembling. Each contact carrier strip has a number of contacts, a first carrier and a second carrier forming positioning structures thereon. Each contact includes a soldering section, a connecting section, a securing section and a contacting section jointed together end to end. The connecting sections of the contacts of different contact carrier strips are perpendicular to both the soldering sections and the securing sections. The contact carrier strips are deposited in a mold. A contact base is insert molded around the contacts for enclosing appropriate sections of the contacts thereby forming a contact module after properly depositing the contact carrier strips in the mold. The soldering sections of the contacts of different contact carrier strips are alternately aligned and remain in the same plane.
