A power sensing and indication circuit includes a first device connector for charging a first device and having a first pin and a second pin, the first pin of the first device connector being connected to an output voltage port of a controller. The power sensing and indication circuit includes a first amplifier. The first amplifier has an inverting input port, a non-inverting input port and an output port. The power sensing and indication circuit includes a first set of multiple photodiodes for emitting light of a first color and a second set of multiple photodiodes for emitting light of a second color. The power sensing and indication circuit includes at least one of a transistor or a digital circuit to cause the first set of multiple diodes to emit light of the first color or the second set of multiple photodiodes to emit light of the second color.

Devices, systems, and techniques are described for providing an indication of the presence of an electrical voltage potential at one or more electrical conductors and/or electrical terminals received in an electrical coupler. Examples of electrical couplers include an illumination coupling comprising a front flange, a rear flange, and an illumination channel extending between the front flange and the rear flange and configured to encircle a portion of the electrical coupler. A plurality of illumination devices positioned at least partially within the illumination channel are configured to provide visible light emissions when illuminated that are indicative of the presence of an electrical voltage potential on at least one of the one or more electrical conductors and/or electrical terminals received within the electrical coupler.

Disclosed is a plug connector having a plurality of electrical contact elements and an elastic sealing body. The elastic sealing body has a transparent sealing ring which is connected to at least one light guide arm which extends away from the sealing ring.

The invention relates to the novel ornamental and utilitarian features of a module/adapter (e.g. male-to-male power adapter) for safety connecting the output interface of a backup power source (such as the outlet of a generator) with an electric circuit (such as a female duplex power outlet of a typical home). Such connection requires a male-to-male adapter which would be unsafe without the disclosed safety features.

A cage includes a housing and a partition assembly mounted in the housing and separating an inner space of the housing into an upper space and a lower space. The partition assembly includes a first support plate and a second support plate arranged horizontally, and at least a pair of support frames disposed between the first support plate and the second support plate to separate the first support plate from the second support plate by a predetermined height. The support frames have a plurality of through holes. The support frames are formed by bending a front end of one of the first support plate and the second support plate.

An electrical connector cage assembly includes a connector casing, a heat-dissipating structure, and a light-guiding part. The heat-dissipating structure is disposed on an outer side wall of the connector casing and includes a base portion and a plurality of fins protruding from the base portion and extending parallel to each other and the base portion. One of the fins protrudes relative to the base portion longer than another one, so that an accommodating space is formed above the shorter fin and extends parallel to the fins. The light-guiding part is disposed above the heat-dissipating structure. A light-guiding rod body of the light-guiding part is accommodated in the accommodating space. An electrical connector uses the electrical connector cage assembly. An electronic apparatus includes the electrical connector and an apparatus casing. A light-output portion of the light-guiding part is disposed toward a light-permeable structure of a panel of the apparatus casing.

The present disclosure provides an electrical connection device that includes a shell, a holding member and a light guiding member. The shell has a front end insertion opening and a rear wall. The rear wall is formed with a first clip structure, and the first clip structure has a sheet body which is integrally formed rearwardly by the rear wall. A clip hole is defined between the sheet body and the rear wall. The holding member has a holding body and a second clip structure which is integrally formed from the holding body and correspondingly cooperates with the first clip structure. The second clip structure has a first arm which is inserted into to the clip hole with an interference fit. A plurality of light guiding pipes are inserted into to the holding body of the holding member.

A chassis connector comprises a housing with an insertion opening (2) for a complementary cable connector, a contact carrier inserted in the housing (1) or formed therein, electrical or optical contacts fixed in the contact carrier, and a front plate which is arranged on the front side of the housing and which, together with an annular ridge extending along at least a part of the circumference of the insertion opening, forms the front end and the outer delimitation of the insertion opening. The front plate is made of a light-dispersing or light-conducting material and has at least one coupling surface for light from an external light source.

A connector comprises a cage and a light pipe. The cage has a top wall, a bottom wall, and a pair of side walls between the top wall and the bottom wall. The light pipe is mounted on an outer surface of at least one of the pair of side walls.

The present disclosure discloses a socket connector including an insulating base and a number of socket terminals. The insulating base includes an outer plastic frame defining a receiving channel and an inner plastic block received in the receiving channel. The inner plastic block includes two sidewalls opposite to each other in a left-and-right direction. The socket terminals are arranged in two rows by positioning symmetrically and respectively on the two sidewalls of the inner plastic block. The socket terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each socket terminal extends along a front-and-back direction perpendicular to both the left-and-right direction and the upper-and-lower direction. A connector assembly including the socket connector and the mated plug connector is also disclosed in the present disclosure.
