Detailed description of the invention

Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with attached Detailed description of the invention of the present utility model is described in detail by figure.

Concrete, described in there is reference signal produce the circuit board of circuit, as it is shown in figure 1, include: first Pcb board 101 produces the second pcb board 102 of circuit with being provided with reference signal；Wherein:

Second pcb board 102 is embedded in the first pcb board 101, the i.e. first pcb board 101 and second Pcb board 102 is positioned in approximately the same plane；

First pcb board 101 is connected with the second pcb board 102, and the first pcb board 101 and the 2nd PCB Fluting 103 it is provided with between plate 102；

It is also preferred that the left fluting 103 is carried out when the processing technology of pcb board.

Described reference signal produces the circuit electrical on circuit and the first pcb board 101 and connects.

Concrete principle is:

The second pcb board 102 being provided with described reference signal generation circuit is embedded in the first pcb board 101 In, the first pcb board 101 is connected with the second pcb board 102, and the first pcb board 101 and the 2nd PCB Be provided with fluting 103 between plate 102, due to the existence of fluting 103 so that the second pcb board 102 with Avoid of the prior art being fully connected between first pcb board 101, reduce the first pcb board 101 Pass to the vibrations of the second pcb board 102 during vibrations, decrease the described vibrations shadow to reference signal precision Ring.

In concrete actual application, described reference signal produces between circuit and the first pcb board 101 It is electrically connected same as the prior art, but between the first pcb board 101 and the second pcb board 102 Mechanical connection the most more advantageously reduce when the first pcb board 101 shakes and pass to the second pcb board The vibrations of 102.

Described in the present embodiment offer, there is reference signal and produce the circuit board of circuit, by above-mentioned setting, make There is described in get reference signal produce the circuit board of circuit and can use paster type encapsulation, it is to avoid have technology by In the problem that the circuit volume using direct insertion components and parts to cause is big and cost is high.

Preferably, described reference signal produces circuit and is: current reference signal produces circuit, or, voltage Reference signal produces circuit.

What deserves to be explained is, described reference signal produce circuit output signal can on the basis of voltage signal or Any one in person's reference current signal, or both all can, be not specifically limited, all in this Shen herein In protection domain please.

In one preferred embodiment of this utility model, the second pcb board 102 is polygon；Concrete, As it is shown in figure 1, the second pcb board 102 is rectangle.

Preferably, as it is shown in figure 1, a limit of the second pcb board 102 is mechanical with the first pcb board 101 It is connected.

Meanwhile, fluting 103 includes: around the fluting on remaining limit of the second pcb board 102.Such as Fig. 1 institute Show that fluting 103 includes: around three flutings of the second pcb board 102.

As above the mechanical connection described in an embodiment, between the first pcb board 101 and the second pcb board 102 Area is the fewest more good, when the rectangle that the second pcb board 102 is as shown in Figure 1, and the only second pcb board One limit of 102 is connected with the first pcb board 101, other three limits of the second pcb board 102 with On first pcb board 101, the most other three sides all maintain a certain distance (the most described three flutings), can With the effective vibrations isolating the first pcb board 101；Further, this distance (width of the most described three flutings Degree) can be not specifically limited depending on the applied environment that it is concrete herein.

Or, the second pcb board 102 is circular or oval (as shown in Figure 2).

Now, it is preferred that described second pcb board is by described circle or a segment boundary curve of ellipse It is mechanically coupled with described first pcb board.

Fig. 2 show the second pcb board 102 by an oval segment boundary curve and the first pcb board 101 It is mechanically coupled；Fluting 103 is: around remaining boundary curve of the described ellipse of the second pcb board 102 Fluting.

In concrete actual application, the second pcb board 102 and corresponding fluting can also use other shapes Shape, rectangle as shown in Figure 1 or ellipse as shown in Figure 2 are only a kind of example, might not limit In this, can be depending on the applied environment that it is concrete, all in the protection domain of the application.

In another preferred embodiment of this utility model, described second pcb board is arranged at described first The region of the mount point of close described first pcb board on pcb board.

The mount point of described first pcb board is described first pcb board when being installed on corresponding equipment, described First pcb board and this equipment are attached and fixing point, in concrete actual application, and this installation Point can be one or more；It is understood that the closer to described mount point on described first pcb board Region, for comparing other regions, its vibrations faced will be the least；So, such region is suitableeer In arranging described second pcb board.

Likewise it is preferred that, the joint face of described second pcb board and described first pcb board, for described the The region of the mount point of close described first pcb board in two pcb boards.

Owing to the mechanical connection area between described second pcb board and described first pcb board is the fewest more good, With reference to above-mentioned principle, joint face between the two is also the best the closer to the mount point of described first pcb board, The vibrations of described second pcb board are passed to when more can reduce described first pcb board vibrations.

The above, be only preferred embodiment of the present utility model, not makees this utility model any Pro forma restriction.Although this utility model is disclosed above with preferred embodiment, but it is not limited to This utility model.Any those of ordinary skill in the art, without departing from technical solutions of the utility model scope In the case of, technical solutions of the utility model are made many by the method and the technology contents that all may utilize the disclosure above Possible variation and modification, or it is revised as the Equivalent embodiments of equivalent variations.Therefore, every without departing from this reality By the content of new technique scheme, according to technical spirit of the present utility model to made for any of the above embodiments any Simple modification, equivalent variations and modification, all still fall within the range of technical solutions of the utility model protection.
