One end of the bonding post is connected with a printed circuit board of the DC-DC converter, and the other end of the bonding post is connected with a client circuit board. The bonding post comprises a conductive connection part and a support part, wherein the conductive connection part traverses the support part, and the support part can be prepared by conductive material. The bonding post is characterized in that the support part is shaped as a truncated cone. The bonding post can effectively reduce occupation space of the printed circuit board of the DC-DC converter.
Description
Technical field
The utility model relates to technical field of semiconductors, the concrete binding post that relates to a kind of DC-DC of being used for transducer.
Background technology
The DC-DC transducer is a kind of electronic equipment that is applicable to a plurality of technical fields, in products such as mobile phone, MP3, digital camera, portable electronic device.The DC/DC transducer is an electric pressure converter of effectively exporting fixed voltage behind the transformation input voltage.The DC-DC transducer is divided three classes: step-up DC-DC transducer, voltage-dropping type DC/DC transducer and buck-boost type DC-DC transducer.
The DC-DC transducer is generally by control chip, inductance coil, and diode, triode, electronic devices and components such as capacitor constitute.And a DC-DC transducer comprises at least one printed circuit board (pcb) and at least one electronic devices and components.The DC-DC transducer needs a binding post (Terminal also often is translated as lead-in wire or joint) to be connected with the client circuit board usually.Binding post uses and comprises at least two functions at the DC-DC transducer, promptly is electrically connected components and parts and mechanical structure and supports.
Weigh one of important indicator of DC-DC transducer in the prior art, promptly under identical functions, realize littler printed circuit board sizes and lower components and parts cost.The printed circuit board (PCB) of DC-DC transducer is as shown in Figure 1 with being connected of client circuit board, and the printed circuit board (PCB) 1 of DC-DC transducer is connected through a binding post 3 with client circuit board 2.This binding post 3 both was electrically connected for printed circuit board (PCB) of DC-DC transducer 1 and client circuit board 2 provide, and was used to keep the two relative position to fix simultaneously.In the prior art the normal binding post that uses as shown in Figure 2, this binding post can further be divided into conductive connecting element 31a, 31b and support component 32.This conductive connecting element 31a, 31b one end are connected with the printed circuit board (PCB) of DC-DC transducer, and the other end is connected with the client circuit board, to be embodied as client fixing predetermined voltage are provided.The effect of support component 32 is fixing for the relative position of printed circuit board (PCB) that guarantees the DC-DC transducer and client circuit board.Existing support component 32 is generally a column type, and wire connecting part 31 therefrom passes.As can be seen from Figure 2, this column type support component 32 can take the DC-DC transducer printed circuit board (PCB) than large space.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and a kind of new binding post that is used for the DC-DC transducer is provided, and this binding post can effectively reduce taking up room to the printed circuit board (PCB) of DC-DC transducer.
For realizing above-mentioned purpose; The utility model provides a kind of binding post of the DC-DC of being used for transducer, and this binding post one end is connected with the printed circuit board (PCB) of DC-DC transducer, and the other end is connected with the client circuit board; Comprise conductive connecting element and support component; Said conductive connecting element passes said support component, it is characterized in that, said support component is a truncated cone.
Wherein, have at least one via hole on the printed circuit board (PCB) of said DC-DC transducer, the said conductive connecting element of said binding post passes at least one via hole on the printed circuit board (PCB) of this DC-DC transducer.The end that said support component cross-sectional area is little is connected with said DC-DC transducer, and the end that cross-sectional area is big is connected with the client circuit board.The cross-sectional area of the end that common said support component cross-sectional area is little is greater than the area of corresponding via hole on the DC-DC transducer printed circuit board (PCB).Common said support component is processed by electric conducting material.
Compared with prior art, the technical scheme that the utility model provided can effectively reduce the space hold to the printed circuit board (PCB) of DC-DC transducer, dwindles the area of this printed circuit board (PCB).
Description of drawings
Can detail and appendedly graphicly further understood through following utility model about the advantage of the utility model and spirit.
Fig. 1 is the DC-DC transducer and the sketch map that is connected of client circuit board;
Fig. 2 is the structural representation of employed binding post in the prior art;
Fig. 3 is the structural representation of the employed binding post of the utility model.
Embodiment
Specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
The binding post that is used for the DC-DC transducer that the utility model provided is as shown in Figure 3.This binding post comprises conductive connecting element 31 and support component 33 equally.Be with the difference of prior art, this support component 33 be shaped as truncated cone, promptly the vertical section of this support component be one trapezoidal.The less end of these support component 33 cross-sectional areas is connected with the printed circuit board (PCB) 1 of DC-DC transducer, and the end that cross-sectional area is bigger is connected with client circuit board 2.In order to realize that simultaneously electrical equipment connects components and parts and mechanical structure supports dual-use function, binding post 3 is processed by metal material usually, and this binding post 3 also can be processed by other electric conducting material certainly.
Compared with prior art, the technical scheme that the utility model provided can effectively reduce the space hold to the printed circuit board (PCB) of DC-DC transducer, dwindles the area of this printed circuit board (PCB), further reduces the cost and the volume of this DC-DC transducer.
The preferred embodiment of the just the utility model described in this specification, above embodiment is only in order to the technical scheme of explanation the utility model but not to the restriction of the utility model.All those skilled in the art according to the design of the utility model through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within the scope of the utility model.
