Abstract: A pin structure of an RJ connector includes a base and eight pins. The eight pins includes a first pin, a second pin, a third pin, a fourth pin, a fifth pin, a sixth pin, a seventh pin and an eighth pin. One end of each pin has a contact part, and the contact parts are aligned in sequence. The other end of each pin is bent to form an inserting part, and the inserting parts are embedded in the base. The distance between the inserting parts of the third and sixth pins is smaller than the distance between the contact parts thereof. An RJ connector module and an RJ connector system with the pin structure are also disclosed. The pin structure is advantageous for decreasing cross-talk and insertion loss generated in the RJ connector, and further increasing the signal definition and accuracy.

Abstract: A magnetic device including a first magnetic core is disclosed. The first magnetic core includes a base having a first edge; a first contacting structure disposed on the base; and a second contacting structure disposed on the base, wherein a distance between an inner surface of the first contacting structure and the first edge is larger than a distance between an inner surface of the second contacting structure and the first edge.

Abstract: A network transformer module includes a first magnetic element, a second magnetic element, and a connection board. The first magnetic element includes a first winding set and a first core, and the first winding set is wound around the first core. The second magnetic element includes a second winding set and a second core, and the second winding set is wound around the second core. The first winding set of the first magnetic element is independent from the second winding set of the second magnetic element, and the first winding set is not wound around the second core. The connection board electrically couples the first winding set with the second winding set. A magnetic element is also disclosed herein.

Abstract: A transformer module includes at least one first casing, at least one second casing and at least one transformer. The first casing has a first receptacle. A protrusion structure is formed on an inner wall of the first receptacle. The second casing is accommodated within the first receptacle. The second casing includes plural winding terminals and a second receptacle. An angle of at least one outer-corner of the second casing is non-right angle so that the protrusion structure and the outer-corner define foolproof structures for limiting the install direction of the second case. The transformer is accommodated within the second receptacle. The transformer includes a magnetic core and at least one coil wound on the magnetic core. Both terminals of the coil are connected to respective winding terminals.

Abstract: The present invention provides a splitter including a seat, a first inner core, a second inner core, a first coil, an outer core and a second coil. The seat has a bobbin, and the first coil is wound on the bobbin. The first inner core and the second inner core, disposed on the bobbin, are assembled with each other to cover the bobbin. The outer core and the first inner core are assembled with each other. The second coil is disposed between the outer core and the first inner core.
