Abstract: Provided are a power conversion device and an operation method thereof. The power conversion device includes an inverter, a transformer, a bidirectional rectifier, and an inductor. An input end of the inverter and an input end of the bidirectional rectifier receive an input DC voltage. The inverter converts the input DC voltage into a first AC voltage for a primary winding of the transformer. A secondary winding of the transformer generates a second AC voltage for the bidirectional rectifier. The bidirectional rectifier uses the second AC voltage to adjust the input DC voltage to generate an adjusted DC voltage for a first end of the inductor. A second end of the inductor provides an output voltage to a load circuit.

Abstract: A modular jack (100) is adapted for mounting on a printed circuit board (6) and has a housing (1) and a plurality of terminals (5) received in the housing. The housing includes a main body (4), an insert module (2), and a presser (3). The main body defines a cavity (40), a pair of grooves (41), and a pair of slots (42). The main body includes a pair of side walls (43). A pair of engaging ribs (44) outwardly project from each side wall and parallel to each other, thereby forming a mounting channel (46) for engaging the printed circuit board between the engaging ribs. As a result, the modular jack is mounted on the printed circuit board. The insert module has a pair of lead sections (21) slidably received in the grooves and a pair of guide sections (20). The presser has a pair of channels (30) slidably receiving the guide sections of the insert module and a pair of latches (33) reliably engaging with the slots of the main body.

Abstract: An electrical connector (7) includes an insulative housing (1) having front and rear faces (10, 20). A first and a second receiving rooms (101, 102), which communicate with each other are defined in the insulative housing (1) and extend forwardly from the rear face (20). A third receiving room (103) is defined in the insulative housing (1) and extends forwardly from the rear face (20) as well. A retaining cavity (6) is in communication with the third receiving room (103). A resilient contact (2) is received in the first receiving room (101) and comprises a first contacting portion and a first connecting portion (23) beyond the rear face (20). A central contact (4) comprises a plate portion (41) received in the third receiving room (103), a fork-type contacting portion (42) extending forwardly from the plate portion (41) and a third connecting portion (43). The plate portion (41) has a retention member (44) for engagement with the retaining cavity (6).

Abstract: An electrical connector (1) includes an insulative housing (10) having a rectangular mating portion (101). The mating portion has a receptacle (131) and an island (142) projecting from a middle of the receptacle. The receptacle has a generally rectangular cross-section defining opposite first and second sides running longitudinally along the housing. The receptacle has a pair of flattened corners (132) on the second side thereof so that the receptacle is in fact a polarizing hexagonal receptacle for allowing a complementary connector to insert therein only in a given orientation.

Abstract: A plug connector (1) includes an insulative housing (2), a center contact (3), an inner contact (4) and an outer contact (5). The housing defines a cutout (23) at a rear end thereof. The center contact has a U shaped tail portion (32) at a rear end thereof, a mating portion (35) for electrically engaging with a complementary connector and an intermediate portion (31) embedded in the housing and connecting the tail portion and the mating portion. The inner contact and the center contact are insert molded with the housing. The inner contact has a mating face (42) exposed in the cutout at a rear end thereof. The outer contact has a reversed U shaped tongue (53) facing opposite to the tail portion of the center contact and extending from a rear end thereof.
