Manufactured round plug connector for the ethernet

Abstract: The invention relates to an industrial connector having a circular connection face that can be manufactured and can be used for transmitting multiplex signals and for ethernet applications. According to a preferred connector of the invention, said connector is a 8-pole round plug and the inner structure can be subdivided into three individual main elements. One part has eight plug contacts that constitute the plug face of the round plug for connecting with a counter-connector, one other part is a connection block that enables a data line to be connected in the field and thus the manufacture thereof, and the third part is a conductor plate which forms a connection element between the connection block and the pin contacts and ensures the connection of the signal transmission path between the pin contacts and the connection contacts of the connection block.

Switching power supply with self-optimizing efficiency

Abstract: A switching power supply is provided that includes: input terminals for the uptake of an input power, output terminals for providing an output power, a circuit disposed between the input and output terminals for transforming the input power and having at least one controllable switch, a control unit for controlling the at least one controllable switch by means of at least one pulse-width modulation signal having variable frequency and variable duty cycle, and having measuring instruments connected to control unit, designed for at least measuring the input current intensity, the input voltage, the output current intensity, and the output voltage, wherein control unit is designed for the purpose of monitoring the efficiency of switching power supply by means of measurement values of the connected measuring instruments, and of optimizing the efficiency by controlling the at least one controllable switch by means of a first digital control loop. Also provided is a method for operating a switching power supply.

Power connection element esp. terminal block - has collector rail holder to hold rail under force of spring clamp so rail contacts lead inserted into clamp

Abstract: The device has an insulating housing (1) and at least one loop-type spring clamp (2). The housing (1) has at least one lead entry opening into which a lead to be connected is inserted. It also has at least one actuation opening into which an actuator tool is inserted to open the spring clamp (2). The housing preferably also has a mounting base for resting on a carrier rail. The clamp spring (2) has a clamp arm with a rectangular or square recess into which the lead to be connected is inserted. It also has a locating arm perpendicular to the clamp arm. The two arms are connected by a bridge. The insulating housing (1) has at least one collector rail holder (12). This is arranged such that a collector rail (13) in the holder (12) lies under the spring force of the clamp spring (2). When an electric lead (4) is inserted, the collector rail 13) makes electric contact, directly or indirectly, with the lead (4).

Overvoltage protection device e.g. for telecommunication equipment - has plastic web projecting into spark-gap between two vertical electrodes which releases electronegative gas when arc strikes

Abstract: An overvoltage protection device for the discharge of transient overvoltages has at least two cylindrical, preferably vertical, electrodes and an airgap between them. There is an element to assist the abrupt discharge in the airgap which projects into the gap like a web. It is made from plastic with low resistance to surface creep currents. Under the effect of an arc, the plastic releases electronegative gases. One electrode is surrounded by the other and there are preferably three such plastic webs between the electrodes. There may be an additional third electrode around the whole assembly with preferably three webs between the this electrode and the one immediately inside it, staggered with respect to the innermost webs. ADVANTAGE - Better arc striking and extinction properties.

Electrical supply or connecting terminal

Abstract: An electrical supply or connecting terminal with a clamping spring and a metal part located in an insulating housing having a conductor inlet opening for an electrical conductor. The clamping spring has a clamping leg and a contact leg, and the clamping leg and the metal part form a spring force clamp connection for the electrical conductor. The contact leg of the clamping spring is arranged essentially perpendicular to the insertion direction of the electrical conductor and a recess is formed in the contact leg for insertion of the electrical conductor. The clamping leg and the contact leg of the clamping spring are bent toward one another with the end of the clamping leg extending through the recess. The metal part has at least one mounting section inserted through the recess of the clamping spring in a direction opposite the insertion direction of the electrical conductor.
