Description

A kind of transformer stack capacitor type device

Technical field

The utility model relates to a kind of transformer stack capacitor type device.

Background technology

In present telecommunication circuit application, develop with continuous with the progress gradually of piling up technology along with integrated, these technology are also increasingly mature.Existing ADSL (Asymmetric Digital Subscriber Line) (Asymmetrical DigitalSubscriber Loop, ADSL) user's plate or Very High Speed Digital Subscriber Line (Very high speedDSL, VDSL) integrated a lot of circuit elements devices on user's plate, as transformer and capacitor, wherein relate to the connection and the layout of a lot of components and parts, need take space certain on the PCB panel and area, when on pcb board, being communicated with as transformer and capacitor, need when designing, pcb board reserve corresponding position and area to transformer and capacitor, under the trend of present high-density plate, the designer more and more pays close attention to the integrated of circuit or dwindles PCB panel area, thereby components and parts miniaturization, the integrated area that dwindles the PCB panel that can be suitable makes densification become possibility.And in factory application, existing integrated components and parts encapsulation mostly is pins type (PTH), and this just need be the components and parts plug-in unit, and wave-soldering etc. is set up punctured element again, lose time and also efficient low.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of raising device integrated level is provided, and reduces the space hold rate of pcb board, and in factory application, the transformer stack capacitor type device that can save time and increase work efficiency.

The technical scheme that the utility model adopted is: the utility model comprises transformer and electric capacity, the pin of described transformer is a patch-type, the lead-in wire of described capacitor is connected with the corresponding pin of described transformer respectively, described capacitor places described transformer inside, forms an independent devices.

The bottom of described transformer is a cavity, and described capacitor places the described cavity of described transformer.

Described capacitor places outside the described cavity of described transformer, and sticker or adhesive tape or plastic strip are fixed in addition again in the outside.

The beneficial effects of the utility model are: the utility model comprises transformer and capacitor, by using the transformer stacked capacitor, improved the device integrated level, reduced the occupancy of device on the PCB space, and saved the process of fixed capacitor on pcb board, again because the pin of described transformer is a patch-type, so in factory application, can adopt surface mounting technology (SMT), realize makeup plate automatically, save the two kinds of different scolding tin patterns that adopt, the speed of work and efficient will improve greatly, thereby save time and raise the efficiency.

Embodiment

Describe summary of the invention of the present utility model in detail below in conjunction with description of drawings.

Fig. 1 and Fig. 2 show the utility model transformer stack capacitor type device the pre-structure schematic diagram are installed, these components and parts comprise transformer 10 and capacitor 20, show pin one 1, pin one 2, pin one 3, pin one 4, pin one 5 and cavity 16 among Fig. 1 on the transformer, capacitor 20 is provided with the lead-in

wire

21 and 22 that links to each other with transformer 10 among Fig. 2, transformer 10 is provided with eight pins, wherein pin one 2 links to each other with 22 with the lead-in wire 21 of capacitor 20 respectively with pin one 3, realizes the current flowing between transformer 10 and the capacitor 20.

Transformer stack capacitor type device architecture schematic diagram as shown in Figure 3.Before stationary transformer 10 and capacitor 20, at first need capacitor 20 and its lead-in wire 21 and lead-in wire 22 are welded, determine then capacitor 20 lead-in

wire

21 and 22 with transformer on institute's pin accordingly, as pin one 2 and pin one 3, after the annexation of determining good pin, 2 lead-in wires in 2 pins described in the transformer 10 and the capacitor 20 weld, the mode that also can adopt fusion links together 2 pins in the transformer 10 and 2 lead-in wires in the capacitor 20, also can adopt other modes that 2 pins in the transformer 10 and 2 lead-in wires in the capacitor 20 are linked together.After the pin welding that finishes transformer 10 and capacitor 20, capacitor 20 is fixed on cavity 16 the insides of transformer 10 belows, in addition sticker or adhesive tape or plastic strip are fixed again in the outside.

When factory's practical application, the pin that utilizes transformer 10 is a patch-type, can adopt Reflow Soldering to be fixed on the pcb board after other components and parts are disguised plate automatically.

In sum, by a kind of transformer stack capacitor type device provided by the utility model, can reduce the reservation area of capacitor on pcb board, thereby improved the integrated level of device on pcb board, reduced the occupancy of device on pcb board, removed the process of fixed capacity on pcb board from, and by using SMD encapsulation, adopt automatic makeup plate to fix, save and adopt two kinds of different scolding tin patterns, thereby saved the time and improved operating efficiency.
