Taking power devices as an example, when the power devices are assembled with PCB boards, the pins need to be assembled into the wave soldering vias on the PCB board, and then wave soldering is performed. However, due to the long length of the pins, during the assembly process, the pin heads are prone to offset or shaking due to the lever effect, resulting in position deviation between the pin heads and the wave soldering vias on the PCB. This deviation not only increases the difficulty of assembly between electronic devices and PCBs, but may also make the assembly process more complicated, thereby affecting the overall assembly efficiency.
[0003] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0038] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.
[0039] It should be noted that, in the description of the present application, terms such as "upper", "lower", "inner", "bottom" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.
[0040] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0041] See also Figure 1-4 , the calibration piece 1 for electronic devices of the present application is described. Figure 1 It is a structural diagram of a power device in the prior art; Figure 2 It is a structural diagram of a calibration component 1 for a power device of the present application; Figure 3 yes Figure 2 Enlarged view of point A in the middle; Figure 4 It is an exploded diagram of the power device of the present application.
[0042] First, Figure 1 As shown, the electronic device is described by taking a power device as an example. In the prior art, the power device includes a device body 2 and a pin 3. The device body 2 is provided with a plurality of pins 3, each of which is arranged along the second direction of the device body 2 (such as Figure 1 The side wall of the device body 2 is directed toward the first direction (eg, Y direction) of the device body 2. Figure 1The pins 3 are bent and extended in the first direction (Z direction shown in the figure), so that the tail 32 of the pin 3 is arranged on the device body 2, and the head 31 is located on the side away from the device body 2 in the first direction. Since each pin 3 is long in the first direction of the device body 2, when the pin 3 passes through the wave soldering via hole on the PCB board and performs wave soldering with the PCB board, the head 31 of the pin 3 is easily offset or shaken due to the lever effect, resulting in a position deviation between the head 31 of the pin 3 and the wave soldering via hole on the PCB, which is not conducive to the assembly of the electronic device and the PCB board.
[0043] The so-called lever effect describes the relationship between force and lever arm. By applying a force to the lever, the part farther from the lever fulcrum is more likely to generate a larger torque (the product of force and lever arm) than the part closer to the lever fulcrum. That is to say, when the fulcrum of the lever is slightly offset or shaken, the head of the lever (the end far away from the fulcrum of the lever) will be significantly offset or shaken. In conjunction with the present application, it means that during the assembly process of the power device and the PCB board, if the length of pin 3 is long, it is actually like a lever, the tail 32 of pin 3 is the fulcrum of the lever, and the head 31 of pin 3 is far away from the tail 32 of pin 3, which is easy to generate a larger torque. This torque will cause the head 31 of pin 3 to be significantly offset or shaken, resulting in a position deviation between the head of pin 3 and the wave soldering via on the PCB, thereby affecting the assembly of the electronic device and the PCB board.
[0044] like Figure 1-4 As shown, in order to solve the problem in the prior art that the assembly of electronic devices and PCB boards is difficult and the assembly efficiency is low due to the long length of the pins 3. The present application is a calibration piece 1 for electronic devices, wherein the electronic device includes pins 3, and the calibration piece 1 includes a calibration body 11, and the calibration body 11 is provided with a connection hole 111 for the pin 3 to be inserted, and the cross-sectional area of the connection hole 111 gradually increases from the head 31 of the pin 3 to the tail 32 of the pin 3; the small end of the connection hole 111 and the pin 3 corresponding to the small end of the connection hole 111 form a tight fit.
[0045] In the present application, the connection hole 111 on the calibration part 1 can be inserted with the pin 3, so that the pin 3 can be limited. In addition, by limiting the cross-sectional area of the connection hole 111 on the calibration body 11, and the cross-sectional area of the connection hole 111 gradually increases from the head 31 of the pin 3 to the tail 32 of the pin 3, it is convenient to connect the calibration part 1 with the pin 3. In addition, by forming a tight fit between the small end of the connection hole 111 and the pin 3 corresponding to the small end of the connection hole 111, this tight fit can not only effectively fix the pin 3, but also calibrate the head of the pin 3, avoid the head 31 of the pin 3 from being significantly offset or shaken due to the lever effect, reduce the difficulty of assembling the electronic device and the PCB board, and improve the assembly efficiency of the electronic device.
[0046] See below for further reference Figure 1-4 , a preferred embodiment of the calibration piece 1 for electronic devices of the present application is introduced. Those skilled in the art will understand that the embodiments described below are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. On the premise that the calibration piece 1 that can be used for electronic devices at least includes a calibration body 11, those skilled in the art can adjust the following settings so that the present application can be applied to more specific application scenarios.
[0047] See also Figure 2 The calibration piece 1 includes a calibration body 11, which is rectangular in shape. The calibration body 11 is provided with a plurality of connection holes 111, which are all arranged at the edge of the calibration body 11 in the second direction, and along the third direction (such as Figure 2 The connection holes 111 are arranged at intervals (in the X direction shown), and the plurality of connection holes 111 correspond to the pins 3 on the device body 2 one by one, so that each pin 3 can be inserted into the connection hole 111. Through the above arrangement, the pins 3 on the device body 2 can be limited by the connection holes 111 on the calibration piece 1, so as to achieve calibration of the heads 31 of the pins 3, and avoid obvious deviation or shaking of the heads 31 of the pins 3 due to the lever effect, thereby reducing the difficulty of assembling the power device and the PCB board and improving the assembly efficiency of the power device.
[0048] The first, second and third directions of the calibration body 11 are respectively consistent with the first, second and third directions of the device body 2. In other words, Figure 1 The X, Y, and Z directions are Figure 2 The X, Y, and Z directions are consistent.
[0049] It should be noted that, since the multiple connection holes 111 correspond one-to-one to the pins 3 on the device body 2, that is, the layout of the connection holes 111 on the calibration body 11 needs to correspond to the arrangement of the pins 3 on the device body 2. For example, when the multiple pins 3 on the device body 2 are arranged at intervals along the circumference of the device body 22, the multiple connection holes 111 on the calibration body 11 also need to be arranged in a circumferentially spaced manner.
[0050] Of course, the present application does not have a fixed relationship between the number of connection holes 111 and the number of pins 3, and those skilled in the art can adjust it according to the setting needs. For example, the number of connection holes 111 can be greater than the number of pins 3, as long as there are connection holes 111 on the calibration piece 1 that correspond to the pins 3 one by one. For example, if the number of connection holes 111 is 5 and the number of pins 3 on the device body 2 is 4, 4 of the 5 connection holes 111 correspond to the pins 3 one by one.
[0051] See next Figure 3The connection hole 111 is a horn hole, and its cross section is rectangular. The cross-sectional shape of the connection hole 111 is the same as that of the pin 3. The cross-sectional area of the connection hole 111 gradually increases from the head 31 of the pin 3 to the tail 32 of the pin 3, so that the pin 3 is inserted from the large end of the connection hole 111 and passes through the small end and extends out of the calibration body 11. The above-mentioned setting method is conducive to the pin 3 being inserted into the connection hole 111 of the calibration member 1, and the small end of the connection hole 111 and the pin 3 corresponding to the small end of the connection hole 111 form a tight fit, so that the pin 3 can be effectively fixed, and the head 31 of the pin 3 can also be calibrated to prevent it from being significantly offset or shaking.
[0052] Of course, the specific arrangement form of the connection hole 111 of the present application is not fixed, and those skilled in the art can adjust it according to the specific application scenario. For example, the connection hole 111 can also be a tapered hole or a stepped hole.
[0053] It should be noted that the present application has no restrictions on the relationship between the cross-sectional shape of the connection hole 111 and the cross-sectional shape of the pin 3, as long as the pin 3 can be inserted from the large end of the connection hole 111 and pass through the small end. For example, the cross-sectional shape of the pin 3 and the connection hole 111 is the same, such as the cross-sectional shape of the pin 3 and the connection hole 111 can both be rectangular. Alternatively, the cross-sectional shape of the pin 3 and the connection hole 111 is different, the cross-sectional shape of the pin 3 can be rectangular, and the cross-sectional shape of the connection hole 111 can be circular, as long as the small end of the connection hole 111 and the pin 3 corresponding to the small end of the connection hole 111 form a tight fit.
[0054] See next Figure 1-4 , the calibration piece 1 also includes a first positioning structure, and the first positioning structure is arranged on the calibration body 11. In addition to the pin 3, the power device also includes a second positioning structure arranged on the device body 2, wherein the first positioning structure corresponds to the second positioning structure, so as to facilitate the assembly of the pin 3 and the calibration piece 1, and improve the assembly efficiency of the two. Specifically, the first positioning structure is a first positioning hole 112, and the second positioning structure is a second positioning hole 21, and the second positioning hole 21 is arranged on the device body 2. When the first positioning hole 112 on the calibration piece 1 and the second positioning hole 21 on the device body 2 are arranged correspondingly along the first direction, and the axis of the first positioning hole 112 and the axis of the second positioning hole 21 are on the same straight line, it is convenient for the pin 3 to be inserted into the connection hole 111 on the calibration piece 1. When the first positioning hole 112 is aligned with the second positioning hole 21, the calibration piece 1 and the device body 2 can be fixed by a positioning pin (not shown in the figure), thereby improving the connection stability between the calibration piece 1 and the pin 3.
[0055] Of course, the specific configuration of the first positioning structure and the second positioning structure is not fixed in the present application, and those skilled in the art can adjust it according to the configuration requirements. For example, the first positioning structure is a positioning hole, and the second positioning structure is a positioning groove; or the first positioning structure is a positioning groove, and the second positioning structure is a positioning hole.
[0056] In addition, the relationship between the first positioning structure and the second positioning structure is not fixed in the present application, and those skilled in the art can adjust it according to the setting needs. For example, the first positioning structure cooperates with the second positioning structure on the power device. Specifically, the first positioning structure and the second positioning structure can be connected by a snap-on method, such as the first positioning structure is a positioning protrusion and the second positioning structure is a positioning hole; or the first positioning structure is a positioning hole and the second positioning structure is a positioning protrusion; or the first positioning structure is a positioning protrusion and the second positioning structure is a positioning groove; or the first positioning structure is a positioning groove and the second positioning structure is a positioning protrusion.
[0057] In addition, the utility model also provides an electronic device, which includes the calibration piece 1 for an electronic device in any of the above embodiments.
[0058] The electronic device further comprises a device body 2, a pin 3 and a second positioning structure arranged on the device body 2. The connection hole 111 on the calibration member 1 can be inserted with the pin 3, so that the pin 3 can be calibrated to avoid the pin 3 on the electronic device being easily deviated or shaken due to the lever effect due to its long length during the assembly process of the electronic device and the PCB board, thereby reducing the difficulty of assembling the electronic device and the PCB board and improving the assembly efficiency of the electronic device.
[0059] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments.
