Electrical connecting terminal, in particular a modular terminal, having a plug link, as well as such a plug link

Abstract: The invention relates to an electrical connection terminal, in particular a modular terminal, having a busbar (1) and having a detachable plug link (2), which has a comb-like link rail (4), for engaging in an opening (3) in the busbar (1) and making electrical contact, the link rail (4) having a rail strip (5) and a plurality of connectors (6) which are connected to the rail strip (5), and at least one, preferably each connector (6), having two separate contact limbs (7, 8), of which at least one is designed to be resilient. In order to ensure good mechanical firm seating and electrical contact of the plug link (2) in the busbar (1) of the electrical connecting terminal, it being intended to ensure simple construction and cost-effective production of the plug link (2) at the same time, it is provided according to the invention that the link rail (4) has two link rail sections (9, 10) which are arranged side by side in the longitudinal direction (L) of the plug link (2) at least in the region of the rail strip (5), and that one contact limb (7, 8) is formed from in each case one link rail section (9, 10) per connector (6).

Jewellery: alloy composition and release of nickel, cobalt and lead assessed with the EU synthetic sweat method.

Abstract: Summary Background Several studies have shown nickel and cobalt release from jewellery by using spot tests, but the metal composition of jewellery is largely unknown. Objectives To evaluate the metal composition of a large worldwide sample of mainly inexpensive jewellery items, and investigate the release of nickel, cobalt and lead from a subsample by using EN 1811:1998-required methods. Methods A total of 956 metallic jewellery components were examined with X-ray fluorescence spectroscopy. A subsample of 96 jewellery items purchased in the United States were investigated for nickel, cobalt and lead release by the use of artificial sweat immersion and plasma optical emission spectroscopy. Results Eighteen elements were detected. The 10 most frequently occurring were, in order of frequency, copper, iron, zinc, nickel, silver, chromium, tin, manganese, lead, and cobalt. Release of nickel was noted from 79 of the 96 US samples (0.01–98 µg/cm2/week), release of cobalt from 35 samples (0.02–0.5 µg/cm2/week), and release of lead from 37 samples (0.03–2718 µg/cm2/week). Conclusions We present here a comprehensive list of the most frequently encountered metals in jewellery and fashion accessories. Different allergenic and non-allergenic metals are utilized. We also report the frequent release of nickel, cobalt and lead from these objects, despite legislative restrictions.

Electrical plug-in connector and electrical plug-in connection

Abstract: The invention illustrates and describes an electrical plug-in connector for the detachable connection of a multicore cable to a mating plug-in connector (2), having a grip body (4) surrounding the cable and the cores (3) of the cable, having a contact carrier (6) receiving and holding a plurality of contact elements (5), and having a rotatably arranged sleeve-like threaded part (7), the individual contact elements (5) being electrically conductively connected to the individual cores (2), and its being possible for the sleeve-like threaded part (7) to be screwed to a corresponding sleeve-like threaded part (9) of the mating plug-in connector (2). In the electrical plug-in connector according to the invention, the assembly of the plug-in connector, in particular of the contact elements (5), is particularly simply possible in that, in the contact carrier (6), a number is formed, corresponding to the number of contact elements (5), of outwardly open grooves (11) running parallel to the longitudinal axis of the contact carrier (6), and in that, in the front end (12) of the contact carrier (6) facing the mating plug-in connector (2), adjacent to the grooves (11), a number is formed corresponding to the number of grooves (11) of passage holes (13), through which the ends (14) of the contact elements (5) that face the cores (3) project in the longitudinal direction of the contact elements (5) when assembled.

Electrical connection terminal

Abstract: The invention illustrates and describes an electrical connection terminal having a clamping spring (2), having a metal part (3) and having a housing (5) which accommodates the clamping spring (2) and the metal part (3) and has at least one conductor insertion opening (4), wherein the clamping spring (2) has a clamping limb (6), an operating limb (7) and a back (8) which connects the two limbs to one another, wherein the clamping limb (6), together with the metal part (3), forms a clamping point () for a stripped conductor (10) which is to be connected, wherein the clamping spring (2) is pivotably mounted in the housing (5) or on the metal part (3) in such a way that the clamping spring (2) can be moved from a first (open) position to a second (closed) position, and wherein a stripped electrical conductor (10) which is inserted through the conductor insertion opening (4) can be inserted into the clamping point (9) in the first position of the clamping spring (2), without the clamping limb (6) having to be deflected against its spring force, and is electrically conductively clamped in the second position of the clamping spring (2) between the end of the clamping limb (6) and the metal part (3). In the electrical connection terminal (1) according to the invention, a simple yet secure connection of an electrical conductor is made possible by an operating element (12) being pivotably mounted in the housing (5) in such a way that the operating element (12) can be moved from a first position to a second position, and that the clamping spring (2) is pivoted out of its first position to its second position when the operating element (12) is pivoted from the first position to the second position.

Housing arrangement with at least two junction boxes

Abstract: A junction box with a square housing and with at least opening and terminal strip for electric cables or lines. With the junction box, a housing arrangement can be modularly built from individual junction boxes that can be reliably connected to one another or to a base part. For attaching the junction box to a second junction box or to a base part, there are two pivotable locking elements on the housing which are movable from a first, open position into a second, locking position, and projecting ribs formed in the area of the outside corners on the housing, the locking element having a U-shape of which a U-bridge is used as an actuating clip and two U-legs, with ends which are bent down, and extend around the ribs on the housing of a second junction box or of the base part in the second, locking position.
