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 pin module of RJ connector includes a circuit board and eight pins, which contain 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. Each pin includes a turning part and a stretching part. One end of the turning part is extended to form a first end of the pin. The first ends of the pins are arranged in a series. One end of the stretching part is coupled to the other end of the corresponding turning part. The other end of the stretching part is extended to form a second end of the pin, and the second ends of the pins clips the circuit board.

Abstract: A modular connector includes a housing, a first circuit board, a first pin set, a second pin set and a second circuit board. The housing includes a first hole and a second hole. The first pin set is extended into the first hole and electrically connected to the first circuit board. The second pin set is extended into the second hole and electrically connected to the second circuit board. The second circuit board is perpendicularly connected to the first circuit board.

Abstract: A connector comprises a housing, a plurality of contact terminals and a signal processing module. The housing has a receiving hole for receiving a plug. The plurality of contact terminals are disposed in the housing for being connected with the plug. The signal processing module is electrically connected with the contact terminals and has a first magnetic component, wherein the first magnetic component comprises a base and a plurality of magnetic cores, the base has a plurality of through holes, each of which has substantially the same size as that of the magnetic core so that the magnetic core is fixed in the through hole, and distances between adjacent two through holes are the same.

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 transformer includes a first magnetic permeable device, a primary winding wire, a secondary winding wire and a second magnetic permeable device. The primary winding wire and the secondary winding wire are wound on the first magnetic permeable device. The second magnetic permeable device includes a first flange and a second flange. The first flange is disposed at one end of the second magnetic permeable device, and the second flange is disposed at the other end of the second magnetic permeable device. The first flange and the second flange are connected to the first magnetic permeable device. The magnetic permeability of the second magnetic permeable device is larger than that of the first magnetic permeable device.
