One aspect relates to a method for a ring electrode, including: providing an outer element with an outer tube and providing a first inner element with a first inner tube having a first core made of a sacrificial material. A material of the outer element and a material of the first inner element have a similar microstructure. A second inner element is provided with a second core made of a sacrificial material; A connection tube is formed by arranging the first inner element and the second inner element within the outer element. The first inner element and the second inner element are arranged concentrically. The composite tube is drawn in a longitudinal direction of the composite tube. The material of the outer element and the material of the first inner element maintain a simialar microstructure. A connection tube disc is seperated from the connection tube. The sacrificial material of the first core is removed and the sacrificial material of the second core is removed to obtain a contacting opening in the ring electrode.

A high-current connector is provided, comprising an insulating body which has at least one contact carrier having at least one contact chamber, which has at least two through-openings on the plug-in side, and at least two electrically conductive plug-in contacts which are arranged parallel to one another in the contact chamber and each have a cable connection region at a first end and a plug-in region opposite at a second end, the plug-in regions of the plug-in contacts being guided through one of the through-openings each of the contact chamber. The high-current plug connector also has an electrically conductive connection element which is inserted into the contact chamber and which has at least two contact receptacles, into each of which one of the plug-in contacts is inserted interlockingly and frictionally by its plug-in region, and the at least two plug-in contacts are electrically conductively connected to one another by the connection element.

In various implementations, a raceway may be provided that is capable of providing power and/or data connectivity to items (e.g., devices, articles of furniture, etc.) coupled to the raceway. The raceway may be low profile. The raceway may be disposed on floor and/or under floor. The raceway may include an integrated power housing. The raceway may include segments that are selected, as desired for an application configuration, and that are coupleable to each other or other components of the raceway (e.g., nodes, joints, etc.). The housing of component(s) of the raceway may include a base and wall(s) with at least curved section and at least one straight section.

A connector connection indicator is mounted in a Luer male connector, or in a Luer female connector, to indicate proper mating of the two Luer connectors. The connection indicator may be or include a light source, a sound producing device (e.g., buzzer), a switch, a tactile connection indicator or an electronic chip. The electronic chip may be interposed between two conductive elements that are mounted in the Luer female connector. When the two Luer connectors are properly engaged, the electronic chip is powered via two electrical terminals. While the electronic chip is powered up it communicates with an external system via two electrical terminals. The external system interprets the communication with the electronic chip as an indication to proper engagement of the two Luer connectors. Some of the connection indicators may be mounted on a circuit board that is embedded in a void in the Luer male connector.

A flange grounding device for grounding between flanges in the case that a predetermined interval is present due to a valve and the like being installed between the flanges when connecting pipes includes: a housing provided with an inner space in which an elastic member is installed, and provided with a rear end brought into close contact with the flange of one side; and an extension member installed inside the housing by being supported at one end of the elastic member, and provided with an opposite end protruded outer side through an inlet of the inner space to be brought into close contact with the flange of another side. Accordingly, even though the interval between the flanges is varied, grounding using one type of grounding device may be reliably performed.

An evaluation jig comprises a female terminal connectable to a male terminal of a charging connector. The female terminal includes a plurality of contact pieces and a support portion. Each contact piece has a flexible piece, and a contact portion protruding toward the center axis from an inner surface of the flexible piece. The flexible piece forms a portion of a cylinder having the center axis. The flexible piece has a length equal to or larger than twice an outer diameter of the cylinder in a direction parallel to the center axis. The flexible piece is elastically deformable so that the flexible piece has a distal end portion to be displaceable in a radial direction of the cylinder relative to a proximal end portion of the flexible piece. The contact portion has a shape curved so as to protrude inward in the radial direction.

A grounding clamp for connecting a cable to an electrical ground includes first and second clamping elements, which tightly abut against one another in an assembled state so that the cable is clampable therebetween. A contact is arranged on the first clamping element to contact a conductive section of the cable in the assembled state. An opening extending through the clamping elements is configured such that a fastener is guidable therethrough and the grounding clamp is connectable to the ground using the fastener. Mutually complementary first and second locking means are also provided. The first locking means are arranged on two opposite sides of the first clamping element and the second locking means are arranged on two opposite sides of the second clamping element. In the assembled state, the locking means are engaged with one another and are arranged on both sides along the cable.
