A cable end connector comprising a plugging member, a plurality of cables, an insulating body, a latch component, a guiding member, and two positioning bumps. The insulating body comprises a plugging surface, a first surface, and a connecting surface. The plugging member protrudes from the plugging surface. One ends of the plurality of cables protrude from the connecting surface. The first surface comprises a latch accommodating groove accommodating the latch component. The guiding member and the two positioning bumps are disposed on the plugging surface and is disposed on a side edge of the plugging surface. The guiding member comprises a limiting notch disposed on one side of the guiding member away from the plugging surface. The preliminary positioning and the secondary guidance positioning can be achieved by providing a limiting notch on the guiding member, which performs the function of limiting after being connected to the board end connector.

Plug and socket assemblies that operatively associate with a safety locking mechanism to enable plugging and unplugging ceiling and wall electrical fixtures safely and conveniently.

A housing is configured to be fitted to a mating housing, the housing including a cylindrical hood into which a fitting protrusion of the mating housing is fittable, the cylindrical hood being configured such that, when the fitting protrusion is fitted into the cylindrical hood, a space between the cylindrical hood and the fitting protrusion is sealed with an annular seal member provided on the fitting protrusion. The cylindrical hood includes, at a distal end of the cylindrical hood from which the housing is fitted to the mating housing, a cylindrical seal portion configured to contact, when the fitting protrusion is fitted into the cylindrical hood, an edge of the mating housing continuously over an entire circumference of the edge and to cover the edge between the cylindrical seal portion and the edge.

The process includes pretreating the biomass with a first basic solution such as sodium hydroxide and mechanically altering the fibers to provide a fluidized biomass. The fluidized biomass is then subjected to high frequency pulses and shear forces without denaturing the individual components of the biomass. The biomass is then subjected to compressive force to separate a first liquid fraction from a first fractionated biomass. The first fractionated biomass may again then be subjected to the same high frequency pulses and shear forces as previously, particularly if there are hemicellulose and/or sugars still present in the first fractionated biomass. Compressive forces are used to separate a second liquid fraction from a second fractionated biomass. The second fractioned biomass is then subjected to compressive forces to provide lignin in water soluble form.

A linear actuator comprises a housing, inside which a spindle assembly, a push rod assembly driven by the spindle assembly, a limit switch for limiting stroke of the push rod assembly, and a motor for driving the spindle assembly are mounted. A connecting seat is disposed on the circuit board for centralizing connection terminals. The motor is electrically connected to the connection terminals. The housing is provided with a plug-in window aligned to the connecting seat. An electric plug of the linear actuator passes through the plug-in window and is plugged into the connecting seat. The electric plug and the housing are fastened together via a mounting component.

An electrical connector (2) comprising a coding housing (4) for electrical and mechanical connection to a compatible connector (3) and comprising a plug body (6) for electrical and mechanical connection to an electrical assembly (5, 14, 15, 16), wherein the compatible connector (3) can be connected to the coding housing (4) along an insertion direction (A), and wherein the coding housing (4) and the plug body (6) have a mechanical connecting device (8). It is provided that the connecting device (8) is designed in order to connect the coding housing (4) and the plug body (6) to one another in an interlocking manner in the insertion direction (A), wherein the connecting device (8) prespecifies an assembly movement (B), which differs from the insertion direction (A), in order to connect the coding housing (4) and the plug body (6) to one another.

A connector is provided with a first housing and a second housing connectable to each other, a detector arranged movably to a standby position and a detection position with respect to the first housing, a pair of second terminal fittings arranged in the second housing, and a shorting terminal arranged in the second housing to short-circuit the pair of second terminal fittings. The detector includes a releasing portion for releasing a short-circuit state of the pair of second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position.

Various connector and sensor assemblies are described. In some embodiments, the connector and sensor assembly comprises a connector and a sensor assembly. The connector can have an opening that has a first surface and second surface that are opposite each other. The connector can have a plurality of retractable electrical connectors that extend from the first surface and a lock structure that is located on the second surface. The sensor assembly is comprised of a body portion and a proximal end. The proximal end has a top side and a bottom side. The top side includes a plurality of electrical contacts that is configured to interact with the plurality of retractable electrical connectors. The bottom side includes a key structure that is configured to interact with the lock structure in the connector.

Systems and methods of deploying seismic data acquisition units from a marine vessel are disclosed. The system can include a mechanical attachment device comprising a cavity formed by interlocking a first member and a second member. Protrusions located on the first member and second member can increase the coefficient of friction between a rope and the mechanical attachment device responsive to an increase in tension on the rope. A lanyard can couple a seismic data acquisition unit to the mechanical attachment device.
