A receptacle socket assembly for lighting equipment comprising: a receptacle having a front side for receiving contacts of a control module, said receptacle housing a plurality of receptacle contacts, each receptacle contact being provided, at a front end, with a front contact portion for being electrically connected with a contact of a control module, and, at a rear end, with a rear contact portion; a wire connector having a front side and a rear side, said wire connector housing a plurality of connector contacts, each connector contact being provided, at a rear end, with a wire receiving contact for receiving and fixing a wire end and, at a front end, with a front contact portion; wherein the rear side of the receptacle and the front side of the wire connector are configured such that the wire connector is removably pluggable in the rear side of the receptacle.

Connector comprising a substantially cylindrical base and a plug connectable to the base in a detachable manner, in which connector a plurality of contacts are mounted in a contact block. The block comprises a flexible membrane through which the contacts extend, the compression of the membrane allowing the sealing at the interface between said membrane and the contacts to be ensured.

A connector includes: a cylindrical terminal; an internal terminal; and a housing. The cylindrical terminal has an engagement portion of its one edge portion and its opposite other edge portion. The one edge portion has a first reduced thickness portion at its circumferential end portion. The first reduced thickness portion has a first protrusion protruding inwardly in a radial direction and extending in an axial direction. The other edge portion has a second reduced thickness portion. The second reduced thickness portion has a second protrusion protruding outwardly in the radial direction and extending in the axial direction. The engagement portion is configured by overlapping the first reduced thickness portion and the second reduced thickness portion and further by locating the first protrusion and the second protrusion to face each other in the circumferential direction to allow an engagement between them in the circumferential direction.

An electrical connector includes an electrically conductive contact element (122) and a support (70). The contact element (122) is supported by an intermediate element (120) made of an elastically deformable material and connected to the support (70). An electrical connection assembly including a connector of the type is also described.

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.

A signal transmission circuit includes: a circuit board stored in a housing; a connector which is mounted on the circuit board and includes a first signal terminal and a first ground terminal; and an integrated circuit which is mounted on the circuit board and includes a second signal terminal and a second ground terminal. The first signal terminal and the second signal terminal are connected to each other by a signal wiring arranged on the circuit board. The first around terminal and the second ground terminal are connected to each other by a ground wiring arranged in a predetermined range including a portion immediately above or immediately below the signal wiring in the circuit board. At least a part of the ground wiring immediately above or immediately below the signal wiring has a high impedance structure formed to be wider than the signal wiring and narrower than a combined width of the first signal terminal and the first ground terminal.

An assembly structure includes an outer joint assembly and an inner joint assembly. At least one terminal portion of the outer joint assembly is hollow to form an accommodating space, the outer joint assembly includes an outer casing and at least one elastic sheet, the elastic sheet has a fixed end and a free end, the fixed end is connected to the outer casing, and the free end is provided with a first engaging part. The outer surface of the inner joint assembly is provided with a second engaging part, the inner joint assembly is used to extend into the accommodating space, and the first engaging part and the second engaging part are used to engage with each other. Through the above design, the assembly structure has quick connect capability, which makes it more convenient for users to use.

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 receptacle socket assembly for lighting equipment comprising: a receptacle having a front side for receiving contacts of a control module, said receptacle housing a plurality of receptacle contacts, each receptacle contact being provided, at a front end, with a front contact portion for being electrically connected with a contact of a control module, and, at a rear end, with a rear contact portion; a wire connector having a front side and a rear side, said wire connector housing a plurality of connector contacts, each connector contact being provided, at a rear end, with a wire receiving contact for receiving and fixing a wire end and, at a front end, with a front contact portion; wherein the rear side of the receptacle and the front side of the wire connector are configured such that the wire connector is removably pluggable in the rear side of the receptacle.
