Abstract:
Das Kontrollgerät ist zur Stromkreisüberwachung vorgesehen und weist ein Gehäuse mit mindestens einem Blechstreifenwiderstand, Leiterstegen, Steckkontakten, einer Leiterplatte und einer Auswertelektronik auf. Die Leiterplatte mit der Auswertelektronik und der Blechstreifenwiderstand sind gemeinsam in dem Gehäuse angeordnet und an der Grundplatte des Gehäuses in verschiedenen Ebenen auf Abstand zueinander festgelegt. Die Leiterstege sind quer zur Ebene des Blechstreifenwiderstandes umgebogen und überbrücken den Abstand zwischen dem Blechstreifenwiderstand bis zur Leiterplatte.
Abstract:
Provided is a power converter which is applied to a power converter equipped with a switching element provided on a line, and a radiator connected to a predetermined potential such as a ground potential. The power converter reduces noise which is caused by a parasitic capacitance generated between the switching element and the radiator and which is output to an input side of the power converter, and the power converter has durability against vibration. A noise eliminator 11 in which a conductive member is covered with insulator is provided between the switching element (semiconductor switch SW) and the radiator (heatsink HS). A flexible connecting line 11c connected to a conductive member 11a of the noise eliminator 11 is connected to an on-board line B1 disposed on a circuit board B.
Abstract:
With the work machine of the present invention, flow device 100 for flowing molten solder from under a circuit board, and backup pin 124 for supporting the circuit board from below while a lead of a leaded component is being inserted into a through-hole, are moved separately under the circuit board. Thus, when the circuit board needs to be supported, the backup pin can be moved to any position, and when solder needs to be applied, the backup pin can be moved to a position that does not obstruct operation of the flow device. Accordingly, as well as guaranteeing operation of the flow device, it is possible to support the circuit board with the backup pin as required, thus improving practicality of the work machine.
