Description

A kind of network transformer structure of improvement

Technical field

The utility model relates to a kind of network transformer, more specifically is meant a kind of network transformer structure of improvement.

Background technology

In ethernet device, when connecing digital broadband network by the PHY chip, the centre all can add a network transformer.After having connect network transformer, it is mainly used in the signal level coupling.Its acting body is present: at first can enhancing signal, and make its transmission range farther; Secondly, make die terminals and external isolation, antijamming capability strengthens greatly, and chip has been increased very big protective effect (as thunderbolt); Once more, when receive varying level (if any the PHY chip be 2.5V, the PHY chip that has is 3.3V) network interface the time, can not impact equipment each other.Network transformer mainly contains effects such as signal transmission, impedance matching, waveform reparation, signal noise inhibition and high voltage isolation.

At present, known network transformer is straight cutting 40pin (40 on a pin), its glue shell structure is a contact pin, be that supplied materials glue shell and stitch separate, be subjected to the restriction of its structure, this network transformer injects stitch in the glue shell hole earlier at production link, is fixed on then on the batten again around pin, behind intact pin, stitch to be left behind and cut pin again, this complex process.In addition, copper cash twines mutually between the inner different windings of glue shell, influence performance, and the spacing between pin and the pin is little, forms short circuit during wicking easily, brings certain difficulty to production.

Summary of the invention

Main purpose of the present utility model is to provide a kind of network transformer structure of improvement, its can overcome that the existing network transformer exists owing to structural limitations causes the complexity of producing and the problem of properties of product aspect deficiency, for people provide a kind of simple in structure, can simplify production technology, reduce the production difficulty, the network transformer of enhancing product performance.

The technical solution adopted in the utility model is: a kind of network transformer structure of improvement, comprise base, some contact pins and lid, wherein, this base comprises top and bottom, this top is concaved with storage tank, the cell wall of the both sides, front and back of this storage tank upwards is convexly equipped with the grafting bar of two correspondences, these two grafting bars are provided with some pin holes through this bottom, some pin holes are separated with spacing between each other, some these contact pins are plugged in some pin holes of this base, and some these contact pins all have upper end and bottom, wherein, the outside of this bottom is extended in this bottom, and the outside of these two grafting bars is then extended in this upper end.

The upper end of some these contact pins is provided with winding slot.

Corresponding some these pin holes are provided with groove on these two grafting bars.

The beneficial effects of the utility model are: the utility model structurally comprises base, some contact pins and lid, wherein, this base comprises top and bottom, this top is concaved with storage tank, the cell wall of the both sides, front and back of this storage tank upwards is convexly equipped with the grafting bar of two correspondences, these two grafting bars are provided with some pin holes through this bottom, some pin holes are separated with spacing between each other, some these contact pins are plugged in some pin holes of this base, some these contact pins all have upper end and bottom, wherein, the outside of this bottom is extended in this bottom, and the outside of these two grafting bars is then extended in this upper end.It can overcome that the existing network transformer exists owing to structural limitations causes the complexity of producing and the problem of properties of product aspect deficiency, for people provide a kind of simple in structure, can simplify production technology, reduce the production difficulty, the network transformer of enhancing product performance.
