Description
Technical field
The present invention relates to technical field of electronic devices, and in particular to a kind of patch type network transformer and its manufacturing method.
Background technique
The signal of electronics is easy the interference by various conduction and radiated noise, Ren Mentong in transmission process
Chang Huiyong filter reduces this interference.Such as network transformer, which are mainly applied in various ethernet devices, such as high property
In the digital devices such as energy digital switch, router, server.Network transformer mainly has signal transmission, impedance matching, waveform
The effects of reparation, signal noise inhibition and high-voltage isolating.
Network transformer (Network Transformer) module is part indispensable in network interface card circuit, its base
This component units mainly includes pulse transformer (Pulse Transformer), common-mode filter (Common Mode
Filter), centre tap capacitor and auto-transformer connect in network transformer and are known as PHYSICAL in the side at the end IC
SIDE, the one end connecting with external data line are known as CABLE SIDE.Network transformer in ethernet device mainly have with
Lower effect: one, transmitting data, and the signal to come from the conveying of data line end is transferred to the end equipment IC by way of coupling；Two,
High_voltage isolation is isolated from the outside the end equipment IC, prevents surge or thunder and lightning injury device IC, enhances anti-interference ability；Three, voltage
Matching, the level to come from the conveying of data line end are not quite similar, are isolated with network transformer, will not cause shadow to equipment IC
It rings；Four, signal noise inhibits, and the common mode choke in network transformer can improve signal quality with filtering clutter common-mode signal.
Network transformer traditional at present is mainly the network transformer of magnet ring class, and manufacturing process is as follows: will manually be twisted
In line good enamel insulated wire coiling to the magnet ring of pulse transformer and common mode choke coil, the lead of above-mentioned coil is extracted out respectively
Twist forms tap together, and welds together, and then the magnet ring for winding line is fixed in plastic casing, remaining lead and modeling
Pin foot on the outside of rubber shell is intertwined, and entire Pin foot is then immersed depainting film in tin furnace.
Above it can be seen that traditional network transformer has following deficiency:
One, the relatively complicated complexity of the manufacturing process of traditional network transformer, in the process wear magnet ring, tap welding, Pin foot
A series of work flows such as kinking, wicking welding require largely manually to complete, and efficiency is extremely low and quality is difficult to ensure, to production
Product industrialized production brings larger difficulty, does not meet the requirement of automatic industrial；In addition because most of is that personnel thread completion,
The consistency of coiling not can guarantee, and the consistency of product electrical property is poor；
Two, there are desoldering rosin joint and even tin etc. is bad for the wicking of traditional network transformer, when client being caused to use open circuit or
In addition short circuit be easy to cause Pin foot coplane degree bad when wicking, influence client and mount use；
Three, traditional network transformer uses magnet ring, and magnetic circuit is closed completely, sensitive to temperature anomaly, it is necessary to select low magnetic conductance
The wide adiabator of rate guarantees temperature range, just can apply to adverse circumstances, it is seen that its requirement to material is more harsh；
Four, traditional network transformer resistance to stress ability is weak, in production and transfer process, plastic casing is be easy to cause to damage,
Pin foot deformation etc..In addition, the number of coating glue insulate to it, pressure resistance is affected, and coated weight because operator it is subjective because
Element fluctuation is larger.
Therefore, the structure and the technological process of production for how improving network transformer, improve the production efficiency of network transformer
And product quality, it realizes the production automation of network transformer, is those skilled in the art's urgent problem to be solved.
Summary of the invention
It is a primary object of the present invention to propose a kind of patch type network transformer and its manufacturing method, aforementioned conventional is solved
Homogeneity of product present in network transformer is bad, electrical reliability is low, application environment is limited, resistance to stress ability is weak, and,
The problem that manufacturing process is many and diverse, production efficiency and the degree of automation are low.
In order to achieve the above object, present invention one of which specific embodiment proposes following scheme:
A kind of patch type network transformer, including being embedded with the plastic base of patching terminal, PCB unit, being mounted on the PCB
Signal Regulation element and plastic cement top cover on unit；The PCB unit is two-sided to be pasted with the Signal Regulation element, wherein
One surface also has for the third electrode with the attachment of the patching terminal of the plastic base；The patching terminal includes being located at institute
State the inner terminal in plastic base and the outer terminal outside the plastic base, and inner terminal and corresponding outboard end
Son conducting；Wherein, the inner terminal is pasted by the third electrode with the PCB unit for having mounted the Signal Regulation element
Dress, paster pin of the outer terminal as the network transformer；The plastic base is closely assembled with the plastic cement top cover

The beneficial effect of the patch type network transformer of the above-mentioned offer of the present invention is: 1) Batch assemblage, manufacture can be achieved
The degree of automation it is higher, good product consistency；2) package bottom is plane, and paster pin is coplanar good；3) to using ring
The limitation of border and making material is not high；4) most machine can be accepted by the outer terminal (i.e. paster pin) of plastic base
Tool stress, to preferably protect internal component；5) when facing the different pad demands of different clients, it is only necessary to change plastic cement
The position of the patching terminal of pedestal, spacing are not related to the modification to the PCB unit with complicated route, therefore in face of diversification
Customer demand, cost is relatively low, workload is few for the repacking of patch type network transformer of the invention；6) PCB is two-sided can mount
Signal Regulation element saves space；And PCB unit only needs change to print electrode and the layout of cabling, can be compatible with different rulers
Very little Signal Regulation element；7) the patch type network transformer pedestal and top cover use injection molding, are unlikely to deform.
Another embodiment of the present invention proposes the manufacturing method of aforementioned patch formula network transformer, comprising:
