Abstract
The utility model provides a printed circuit board (PCB) type miniature voltage transformer, which comprises a housing and a coil. A pin socket is arranged at the bottom of the housing. The coil is packaged in the housing, and comprises a core, a primary winding and a secondary winding, wherein the primary and secondary windings are sequentially wound on the core, and are led out by a lead respectively. Moreover, an insulating tape layer, a shielding layer and an insulating tape layer are arranged between the two windings, and are sequentially overlapped and wrapped on the core. The shielding layer is led out by a lead. The leads are connected with pins of the pin socket in a one-to-one correspondence way after leading out the primary winding, the secondary winding and the shielding layer respectively. The PCB type miniature voltage transformer with a changed structure has the advantages of rational and reliable design, smaller volume, higher accuracy, more convenience for PCB type mounting, higher insulating property and higher moisture resistance; a plurality of shortcomings of the conventional PCB type voltage transformer are well overcome; and the requirements of practical work can be met.
Description
Technical field
The utility model relates to the technical field of electric elements, refers in particular to a kind of pcb board type voltage transformer that declines.
Background technology
At present; The existing voltage transformer that is used for pcb board is confined to itself architectural feature; Shortcoming such as also the ubiquity volume is big, precision is low, dismounting is difficult, poor insulativity, moisture resistance are low; Expected Results when being difficult to reach practical application, so, a kind of voltage transformer that is used for pcb board brand-new, necessary requirement in the time of solving above drawback and also can reach real work be badly in need of now on the market.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, the type voltage transformer that provides that a kind of volume is little, precision is high, pcb board easy for installation, that insulating properties is high, moisture resistance is high declines.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of pcb board type voltage transformer that declines; It includes the bottom and the shell of Pin needle socket is housed and is encapsulated in the coil in this shell, and wherein, described coil includes iron core and is wound on elementary winding and the secondary winding on this iron core successively; This elementary winding and secondary winding are respectively with drawing simultaneously; And between this two-stage winding, be provided with insulating cement layer of cloth, screen, the insulating cement layer of cloth is overlapping successively wraps on the iron core, screen is with drawing, the lead-in wire after elementary winding, secondary winding and screen are drawn respectively with corresponding one by one joining of Pin pin of Pin needle socket.
Described Pin needle socket is provided with six Pin pin, and wherein, two Pin pin connect the lead-in wire of elementary winding respectively, and a Pin pin connects the lead-in wire of screen, and a Pin pin is empty pin, and other two Pin pin connect the lead-in wire of secondary winding respectively.
Described shell is through the epoxy encapsulation coil.
Described iron core is an annular core.
Described shell is a plastic shell.
Described lead-in wire is the PVC lead-in wire.
The utility model is after having adopted such scheme; Its great advantage is the reasonable in design reliable of the utility model; When changing itself structure; Smaller volume, precision uprise, the pcb board formula install to become convenient, insulating properties uprises, moisture resistance uprises, and have overcome many drawbacks that the existing voltage transformer that is used for pcb board exists well, required requirement in the time of reaching real work simultaneously.
