Description
Background of the Invention
[0001] 1. Field of the Invention
[0002] The present invention relates to a jack and in particular to a keystone jack with a double-cross isolation structure to avoid the crosstalk phenomenon.
[0003] 2. Description of Prior Art
[0004] When the electronic signals are transmitted along the layouts of the printed circuit board, the electromagnetic waves of the electronic signals are transmitted from one side of the integrated circuit to another side of the integrated circuit along the layouts of the printed circuit board as well, so the crosstalk happens. Due to the electromagnetic induction, the voltages and the currents are varied transiently by the electromagnetic waves in the transmission process.
[0005] The electromagnetic waves are induced by the electric fields and the magnetic fields with time variation. In fact, the electric fields and the magnetic fields exist not only in each kind of layouts in the printed circuit board. The energy of a plenty of electromagnetic waves exists outside the layouts. So when the electronic signals are transmitted along the lead wire and there are other wiring lines nearby, other wiring lines will be impacted by the electric fields and the magnetic fields of the electronic signals.
[0006] According to the Maxwell equation, the electric fields and the magnetic fields will induce the voltages and the currents in the lead wire nearby, so the electric fields and the magnetic fields induced from the transmission process of the electronic signals will cause the electronic signal interferences. This phenomenon is called the crosstalk phenomenon.
[0007] Beside the crosstalk phenomenon in the printed circuit board mentioned above, the crosstalk phenomenon exists in the conventional keystone jacks or other connectors as well. The distance of the pins of the puncturing terminals is short because the volume of the keystone jack is small. The core wires are closed because the distance of the pins of the puncturing terminals is short, so that the electricity is not stable when the electronic signals are transmitted. The electromagnetic waves induced by the puncturing terminals will impact the puncturing terminals nearby, so that the impedance characteristics are not stable and the transmission signals are decayed.
Summary of the Invention
[0008] Therefore, the main object of the present invention is to solve the crosstalk phenomenon in the conventional keystone jacks. After a double-cross isolation structure is installed in the puncturing terminals in the keystone jack, the electricity is more stable when the keystone jack is used. The crosstalk interferences are decreasing, and the impedance characteristics are more stable, and the transmission signals are not decayed.
[0009] In order to achieve the object mentioned above, the present invention provides a keystone jack including a cover body, a lining body, a carrier body, a printed circuit board, a housing, and a flap.
[0010] The cover body includes a space. A joining part in barb shape is on each of the four corners of the space. The space includes a bottom surface. An elongated partition plate is on the bottom surface. The elongated partition plate perpendicular interlaces a short partition plate. The short partition plate includes a bottom part. A distance is formed between the bottom part and the bottom surface. Besides, a first neck part is extended from a side of the cover body. The first neck part includes a groove.
[0011] The lining body is installed in the space. The lining body has two symmetric edges. The two edges have a plurality of symmetric slots. The slot has a lateral insertion port. A connection part is between the two edges. The connection part has a stud being in U-type and having a first channel. Besides, a separation plate is between the two edges. The separation plate includes a convex wall having a second channel opposite to the first channel. An opening is formed between the separation plate and the connection part.
[0012] The carrier body includes a first bearing part, a second bearing part, and a metal spring. The first bearing part includes a plurality of puncturing terminals inserting opposite to the slots. One side of the puncturing terminal is a welding part through the first bearing part. The second bearing part includes a plurality of conducting pins. One side of the conducting pin is a pin part.
[0013] The printed circuit board includes a plurality of holes. After the welding parts and the pin parts are through the holes of the printed circuit board, the welding parts and the pin parts are electrically connected to the printed circuit board.
[0014] The housing includes a fore end part and a rear end part. The fore end part and the rear end part have an assembling space. The fore end part includes a port. The rear end part includes a joint part. Besides, a coupling part is in the bottom of the housing.
[0015] The flap includes a cover splicing to the rear end part. One side of the cover is a second neck part opposite to the first neck part of the cover body. An axial part is in the other side of the cover. The axial part is pivotally connected to a resilient body. The resilient body is through the coupling part.
[0016] Moreover, when the lining body is installed in the space, the elongated partition plate and the short partition plate of the space are through the first channel, the second channel, and the opening to form a double-cross isolation structure, so that the electricity is more stable when the keystone jack is used. The crosstalk interference is decreasing, and the impedance characteristics are more stable, and the transmission signals are not decayed.
