A connector comprising a cylindrically shaped socket and a plug that may be connected to the socket in a removable manner, in which a plurality of contacts are disposed being mounted in a contact block. It comprises a ring with ogive shaped parts (21) assembled in a membrane (22), the ogive shaped parts and the membrane being covered by a locking spring (25).

One variation of a portable radio system includes: a portable radio configured to transmit and receive audio communication, including a connector receptacle arranged on a rear face of the portable radio and a channel extending from the connector receptacle; a cable, configured to couple the portable radio to a secondary device, including a straight section configured to seat within the channel and defining a length greater than a length of the channel; a connector, coupled to the straight section of the cable, configured to seat within the connector receptacle to couple the cable to the portable radio in an upward and downward orientation; and a clip including a base section configured to transiently couple to the body over the connector and a clamp section configured to pivot relative the base section and to attach the portable radio to a user.

A charging system for a battery-operated machine is disclosed. The charging system includes a charging receptacle having a power connection and a signal connection, with the charging receptacle configured to receive electrical current via the power connection from a power supply plug. The charging system further includes a heat rejection element thermally coupled to the charging receptacle, a temperature sensor, and a charging controller operatively coupled to the temperature sensor and the charging receptacle. The charging controller is configured to receive a temperature signal from the temperature sensor, the temperature signal being indicative of a charging-receptacle temperature. The charging controller is further configured to transmit, via the signal connection to the connected plug, a control signal to adjust (e.g., raise or lower) the electrical current supplied to the power connection.

Devices and systems having a plug and socket connection for resisting or preventing liquid, moisture, vapor, and the like, from contacting the internal electrical circuitry, is provided. Such an electrical device includes a power source socket coupled to a connector and a cap seal coupled to the connector. The power source socket further includes power source wires and the connector includes power distribution wires. The connections between the power source socket and the connector, between each pair of connectors, and between the connector and the cap seal are sealed to exclude moisture/liquid from causing shorting, as is described in more detail below.

An electronic equipment comprises a case and a connector which is attached to the case. The connector comprises a housing and a waterproofing member. The waterproofing member is sandwiched by a mating connector and a side portion of the housing in a second direction when the connector is mated with the mating connector. The waterproofing member has at least one first contact portion, at least one second contact portion, at least one third contact portion and at least one fourth contact portion. The third contact portion is pressed against the side portion in the second direction by elasticity of the waterproofing member upon the mating of the connector with the mating connector. The fourth contact portion is pressed against and in contact with the mating connector in the second direction by the elasticity of the waterproofing member upon the mating of the connector with the mating connector.

The invention relates to an electrical plug connector, with a housing (1) with at least one insertion opening (2) for a complementary plug connector and a contact carrier (3), arranged in the housing (1), for the electrical contacts accessible through the insertion opening(s). Two concentrically arranged housing parts (5, 6) are connected to one another via a base (8) on the end opposite the at least one insertion opening (2). Between the housing parts (5, 6), an annular intermediate space (7) is formed as an annular receiving opening for the plug extension of a complementary plug connector. A receiving space (9) for the contact carrier (3) is provided inside the internal housing part (6).

A connector for sealably engaging contacts therein and permitting reliable disengagement thereof includes a first unit having one or more elongated shafts. Each elongated shaft includes at least one first contact. The connector further includes a second unit having a body with one or more channels therein. Each channel includes at least one second contact. Each channel is configured to receive at least a portion of one of the elongated shafts therein to permit electrical connection of the one or more first contacts to the respective one or more second contacts. The second unit further includes an axial slit extending radially outwardly from each channel toward an outer surface of the body of the second unit. Each slit of the second unit is a circumferentially discontinuous portion of the channel configured to prevent the second unit from forming a constrictive belt around the one or more elongated shafts therein.

A tool configured to apply a lubricant includes an insert disposed within a shroud of an electrical connector. The insert has a central cavity and passages extending from the central cavity to portals defined in an outer surface of the insert and a spray valve disposed within the insert configured to dispense a lubricant mist into the central cavity, through the passages to the portals, and onto a seal wiping surface of the electrical connector.

A connecting plug includes a locking pin arranged at a connector face. The locking pin has at least one latching element and a counter-piece. The latching element is configured for engaging with at least one counter-latching element of a second connector part. The locking pin includes a spring element configured for resiliently pressing the at least one latching element and the counter-piece against each other. The counter-piece is shaped and configured for pressing the at least one latching element in a radially outward direction and for positively locking the at least one latching element in an engaged position as soon as the at least one latching element is engaged with the at least one counter-latching element.

A dispensing seal includes a base seal comprised of a first material. The base seal includes at least a top surface and a bottom surface and a cavity defined therein, wherein the bottom surface includes an opening to the cavity. A second material is located within the cavity of the base seal, wherein a viscosity of the second material is less than a viscosity of the first material.
