A wall-mounted electrical-connector-engaging assembly for axial engagement with an electrical connector, the assembly including (a) a wall-surface adapter having front and back faces and attached to a wall over an opening in the wall and (b) a backcap. The adapter back face has a plurality of wire-connection points for installation of a corresponding plurality of wires, and the adapter front face has a plurality of slidably-engaging electrical connection points for engagement in at least an axial direction with the electrical connector. The backcap surrounds the plurality of wire-connection points and adjacent portions of the corresponding plurality of wires connected thereto, and includes a twist lock for installation on the wall-surface adapter.

A connector includes an outer housing, an inner housing fitted to the outer housing, and a detection member assembled to the outer housing and restricted from being separated in a removal direction. The detection member has a flexible lock arm and a member-side protrusion formed on a free end side of the lock arm and facing an outer-side protrusion in the removal direction in an assembled state. When a locking arm gets over the outer-side protrusion and is locked to the outer-side protrusion, the locking arm moves in an insertion direction while being elastically deformed, and elastically returns after getting over the outer-side protrusion to press the member-side protrusion outward an inner housing accommodating space, so that the lock arm allows the outer-side protrusion and the member-side protrusion to be in a non-facing state in the insertion/removal direction, and allows the detection member to be separated in the removal direction.

A snap-in socket panel with a night lamp includes a first panel, a second panel, a resilient sheet bracket arranged vertically to the flat portion, and a resilient sheet connected to the resilient sheet bracket by a plug-in structure. The plug-in structure includes a slot provided on the resilient sheet bracket and an insertion block provided on the resilient sheet. The opening direction of the slot is set towards the first panel. During assembly, the insertion block on the resilient sheet is inserted into the slot on the resilient sheet bracket from bottom to top, to connect the resilient sheet and the resilient sheet bracket, and then connect the second panel to the first panel. The second panel can block the opening of the slot, thereby preventing the resilient sheet from falling out. The socket panel has fewer components, a simple structure, and faster, more convenient assembly.

An electronics housing assembly includes a first housing portion and a second housing portion removably connected to the first housing portion to define an interior space that contains electronics components. A first group of the electronics components is connected to the first housing portion and a second group of the electronics components is connected to the second housing portion. A connector alignment and retention panel is connected to the first housing portion. The connector alignment and retention panel includes a connector support platform with a first connector mounting location. A first electrical connector that is part of the first group of the electronics components is operatively engaged with the first connector mounting location of the panel such that the first electrical connector is mounted on the panel and located in a select position relative to the first housing portion. A first corresponding electrical connector that is part of the second group of said electronics components is operatively secured to the second housing portion and is operatively engaged with the first electrical connector mounted on the panel.

A fastening device for fastening an electrical terminal to an electrically conducting post includes a spring and a locking device retaining the electrical terminal on the electrically conducting post in a locked position of the fastening device. The spring is at least partially loaded in the locked position.

A power supply device includes a power supply housing having an accommodating space and an accommodating opening, a hybrid wire-to-wire connector structure and a circuit board disposed in the accommodating space. The hybrid wire-to-wire connector structure includes a connecting seat and an adapter seat. The connecting seat has a signal line terminal and a power line terminal. The connecting seat is disposed in the accommodating opening through an annular rib. The adapter seat has a signal conduction end and a power conduction end. The adapter seat has formed a hook corresponding to the annular rib. The connecting seat and the adapter seat are combined through the signal conduction end inserted in the signal line terminal, the power conduction end inserted in the power line terminal and the hook clamped with the annular rib. Therefore, the power and signal connectors are integrated so as to simplify the assembly.

This disclosure details roof rail power outlet systems for establishing power sources on vehicle roofs. An exemplary roof rail power outlet system may include a roof rail cover and a power outlet assembly received by a housing of the roof rail cover. The power outlet assembly may be snap connected to the housing of the roof rail cover. The power outlet assembly includes a power socket that is capable of providing a source of power at the vehicle rooftop.

A patch panel assembly, bezel and modular jacks are disclosed which allow modular jacks to be positioned closer together to increase patch panel density. In particular the modular jacks are equipped with features which engage openings which are offset, allowing for the modular jacks to be positioned closer together, in particular when arranged in adjacent parallel rows.
