Abstract

The utility model discloses a novel network isolation transformer. The novel network isolation transformer comprises a pedestal, a top cover, pins, a PCB and coils. Two rows of pins, evenly spaced from each other, arranged orderly and consistent in length, are inserted into each side edge of each of frames at two sides of the pedestal. A row of pins consistent in length is inserted into each of side edges at two heads of the pedestal. The pins penetrate the side edges of the two sides and the heads of a pedestal frame. A coil unit is arranged inside a groove of the pedestal frame. The top end of each of the pins on the two side edges is welded to the PCB and connected with a primary phase and a secondary phase of each corresponding coil. The top end of each of the pins on the side edges at the two heads is connected with one corresponding coil and then passes through the PCB to be connected, on the PCB, with a POE power line end stand. The bottom end of each pin is connected with external signal input and output ends. The top cover is a concave box cover with a direction round point mark and having a POE power line power supplying wire inlet. The top cover is buckled to the pedestal. The novel network isolation transformer is suitable for signal transmission, impedance match, high-voltage isolation electromagnetic pulse and electrostatic protection, and has a POE function.

Description

A kind of new network isolating transformer

Technical field

The utility model relates to network transformer, particularly a kind of network transformer of supporting POE.

Background technology

Existing network isolation transformer, is generally applied in high-performance digital switch, SDH/ATM transmission equipment, ISDN.ADSL.VDSL power receiving equipment integrated service digital device, FILT optical fiber loop equipment, on the equipment such as Ethernet switch.But existing network isolation transformer can not be supported POE, can not provide I/O channel for POE/POE+.

Utility model content

The utility model, in order to overcome the deficiencies in the prior art, provides the network isolation transformer of a kind of POE of support.

The technical solution of the utility model is: a kind of new network isolating transformer, comprise base, upper cover, stitch, PCB circuit block and coil, be inserted with respectively the consistent stitch of the two evenly distributed neat length in row interval at the both sides of the base each side of frame, at base two, side is inserted with respectively the stitch that single length is consistent, stitch runs through base frames both sides and two side, in base frames groove, be provided with line package, dual-side stitch top is welded on PCB circuit board elementary with line bag, secondary being connected, after being connected with coil, side stitch top, two passes PCB circuit board, on PCB circuit board, be connected with POE mains terminals seat, stitch bottom and external signal input, output is connected, described upper cover is the matrix lid that is labeled with direction round dot and a POE Power supply incoming line, be interlocked with base.

The every row of described dual-side stitch 2-48 root.

Described two side stitch has 1-16 root.

The utility model, in POE and POE+ circuit, can also provide for this type of little function device the technology of direct current supply when transmission of data signals, POE can provide the power of 350MA/12.95W, and POE can provide the maximum 700MA/30W power of left and right.POE, by the principle of cable power supply, when application data power supply, is added in DC power supply at the mid point of transmission transformer, does not affect the transmission of data.

The utility model network transformer is the most desirable device that electric current injects, through-current capability and bear DC bias current ability and met IEEE802.3af (POE) and 802.3af (POE+) standard.

The utility model Main Function: signal transmission, impedance matching, high pressure isolation electromagnetic pulse, electrostatic defending, band POE function.
