    Abstract: A relay includes an armature, a yoke configured to be electromagnetically coupled to the armature, and a bracket-shaped clamping spring. The armature lies at least partially flat on the yoke, and a receiving depression is partly formed in the armature. The bracket-shaped clamping spring surrounds the armature and the yoke on an end face such that the armature is fixed on the yoke. The bracket-shaped clamping spring has a first clamping limb arranged in the receiving depression of the armature, and a second clamping limb lying on the yoke. The first clamping limb has an angled tab which engages elastically into a recess formed in the receiving depression of the armature.

  • Publication number: 20210074500
    Abstract: A relay for assembling in terminal blocks includes an electromagnetic drive arrangement including an armature, an armature bearing spring, and a yoke. The armature is at least partially spaced from the yoke, is movably mounted, and is reduces the distance between the yoke and the armature under an effect of an electromagnetic force. The armature bearing spring applies a spring force counteracting the electromagnetic force. The yoke interacts electromagnetically with the armature to apply the electromagnetic force. A contact spring has a first contact surface and a contact arm, and the contact arm is spaced from the first contact surface and comes into contact with the first contact surface via a pressure force acting to establish an electrical connection between the first contact surface and the contact arm. An insulating element electrically isolates the armature from the contact arm and actuates the contact arm to produce the pressure force.

  • Patent number: 9856298
    Abstract: The invention relates to modified antibiotic peptides, in particular derivatives of apidaecin and oncocin, preferably having increased stability, reduced immunoreaction, and improved pharmacokinetics. In the invention, the peptide antibiotics are reversibly protected by means of a linker having the polymer polyethylene glycol (PEG). The peptide linker contains a recognition sequence for trypsin-like serum proteases. In the apidaecin derivatives, the linker and the PEG are bonded to a side chain. In the serum, the linker is cut by serum proteases and PEG is separated off. The released peptide still contains remnants of the linker, which are still bonded to the amino group in the side chain. Astonishingly, said remaining remnants of the linker impair the activity of the antimicrobial peptide only a little or not at all.
