Presented are a method and apparatus for attachment and evacuation. The apparatus includes a housing having an opening, and a motor maintained within the housing, the motor operable to urge a fluid to pass through the opening. The apparatus further includes an adjustable element maintained within the opening, the adjustable element operable to change a size of the opening to a plurality of different diameters, and a knob moveably affixed to the housing, the knob operable to change the adjustable element to the plurality of different diameters.

A connector includes a dielectric having a mating face, an inner contact disposed in the dielectric, and a conductive layer disposed on or within the mating face. The conductive layer is electrically isolated from the inner contact.

Coaxial cable adapters and connectors are provided that are particularly suited for use in high power applications. A flowable insulator filling a cavity within the adapters and connectors improves heat conduction from inner conductors outwards while providing electrical insulation around the inner conductors.

Herein is an electrical connector with an inner conductor extending in the mating direction, a main body portion extending in the mating direction to accommodate one end of the inner conductor and to which a coaxial cable is attached, and a mating portion extending in the mating direction to accommodate the other end of the inner conductor and mates with a counterpart connector. An accommodating space in the main body portion accommodates one end of the inner conductor. An attachment aperture communicates with the accommodating space by extending in the lateral direction perpendicular to the mating direction and attaches the coaxial cable to the main body portion to connect its center conductor to one end of the inner conductor. The attachment aperture of the main body portion includes a tapered portion decreasing in diameter toward the accommodating space at the end proximal to the accommodating space.

The invention relates to an electronic module for recording information of a drug delivery device, the electronic module comprising at least one connector, wherein at least one connector is adapted to be connected to a port of the drug delivery device and wherein at least one connector is adapted to be connected to a port of a computer. Furthermore, the invention relates to a drug delivery device, comprising a port for connecting to the connector of the electronic module.

An electrical equipotential connection device having: a connector (1) that includes: a first electrical connector element (2); at least one resilient tab (4); a socket (9) that includes: a contact surface (12); a second electrical connector element (20); at least one housing (14) suitable for cooperating with the at least one resilient tab (4); a disconnection track (17) adjacent to the housing (14) and extending substantially parallel to the insertion direction (21). The connector (1) is rotatable with respect to the base (9), about the insertion direction (21), between: a stable locking position in which the resilient tab (4) is inserted into the housing (14); an unlocking position in which the resilient tab (4) is resiliently deformed and disposed on the disconnection track (17).

The present disclosure relates to a push-pull coaxial connector comprising: an external conductor, where the external conductor is configured to internally receive the matching external conductor of a mating connector, with concave parts or through holes on the inner surface of the side wall of the external conductor that house retainers and corresponding matching concave parts on the outer surface of the side wall of the mating external conductor, of which, there are one or more protrusions on the outer surface of the side wall of the external conductor; a sleeve surrounding the external conductor, where the sleeve is able to slide between the front position and rear position along the external conductor and is able to rotate around the circumference of the external conductor, of which, there are one or more corresponding notches to receive one or more protrusions on the rear surface of the sleeve; wherein, when the sleeve is at the front position, one or more protrusions are staggered away from one or more notches and abutted on the rear surface of the sleeve to prevent the sleeve from moving backward, and at this point, part of the retainer is in the concave part or through hole of the external conductor and part of it is in the mating concave part of the mating external conductor, thus maintaining the connection between the coaxial connector and mating connector; wherein, when the sleeve is at the rear position, one or more protrusions are received in one or more corresponding notches, and at this point, the retainer fully leaves the matching concave part of the mating external conductor, thus separating the coaxial connector and the mating connector. The push-pull coaxial connector uses a simple concave-convex structure, which locks the front and rear positions of the push-pull structure of the coaxial connector and it has a simple structure and is low-cost.

A high-power plug connection system is provided comprising a cable connection housing for connecting at least two electric high-power plug connectors in order to transmit and/or distribute high electric current strengths and/or high electric voltages, at least two insulating bodies for receiving a respective high-power contact and at least one electrically conductive rail, wherein the longitudinal axes of the high-power contacts are arranged essentially in one plane in an offset manner from each other, the high-power contacts being connected together in an electrically conductive manner by the electrically conductive rail, said high-power contacts being provided with at least one recess, into which the rail at least partly fits, and wherein an interior space formed in the cable connection housing is at least partially encapsulated with a dielectric substance.
