現有的變壓器一般包含有一變壓電路板，變壓電路板的其中一面設有電子元件且其另一面需以金屬罩罩蓋以隔離電磁干擾。然而金屬罩遮蔽了電子元件的焊接點，為使電子元件能夠進行自動化焊接，金屬罩無法連同電路板及電子元件置入焬爐進行自動化焊接。金屬罩必需另以人工焊接而固定於電路板。The existing transformer generally includes a transformer circuit board, one side of the transformer circuit board is provided with electronic components, and the other side of the transformer circuit board needs to be covered with a metal cover to isolate electromagnetic interference.

屏蔽金屬罩300罩蓋電路板100的背面102，且屏蔽金屬罩300設置對應組裝端子200的一導電銷400。於本實施例中，屏蔽金屬罩300為鋁或不銹鋼製成以用於阻隔電磁干擾。導電銷400可以與屏蔽金屬罩300以沖壓方式一體成形而簡化加工。導電銷400也可以另行鉚接於屏蔽金屬罩300以強化連結結構，另外，導電銷400可以為銅製以利於焊接，其可以先行插接組裝端子200固定後再焊接於穿孔103，藉此減少人工焊接的不穩定性。The shielding metal cover 300 covers the back surface 102 of the circuit board 100 , and the shielding metal cover 300 is provided with a conductive pin 400 corresponding to the assembly terminal 200 .

When the conductive pin 400 is inserted into the clamp 220 , the guiding slope 222 can guide the conductive pin 400 to be easily inserted into the clamp 220 .

以最簡單實施方式而言，屏蔽金屬罩300設置單一導電銷400，電路板100對應設置單一組裝端子200即能夠達成本發明藉由扣接方式將蔽金屬罩組裝至電路板100之功效。本發明的實施例中，較佳地，屏蔽金屬罩300設置有二導電銷400，電路板100的正面101則對應設置二組裝端子200，電路板100上也分別對應各導電銷400及相對應的各組裝端子200之位置而設置二穿孔103，然而，本發明不限定導電銷400及其相對應組裝端子200及穿孔103之數量。In the simplest embodiment, the shielding metal cover 300 is provided with a single conductive pin 400, and the circuit board 100 is provided with a single assembly terminal 200, which can achieve the effect of the present invention to assemble the shielding metal cover to the circuit board 100 by buckling. In the embodiment of the present invention, preferably, the shielding metal cover 300 is provided with two conductive pins 400, and the front surface 101 of the circuit board 100 is correspondingly provided with two assembly terminals 200, and the circuit board 100 also corresponds to each conductive pin 400 and the corresponding Two through-holes 103 are provided for the position of each assembly terminal 200 , however, the present invention does not limit the number of conductive pins 400 and corresponding assembly terminals 200 and through-holes 103 .

多個導電銷400以及組裝端子200之配置另可以達到定位之功效，其具體說明如後。其中一組裝端子200在相對應的導電銷400上之施力方向與另一組裝端子200在相對應的另一導電銷400上之施力方向不平行。藉此能夠避免屏蔽金屬罩300沿各導電銷400的橫向位移。具體而言，本發明的電壓轉換裝置，其各導電銷400呈扁平狀，且各導電銷400的法線方向相互不平行。各具分別夾持對應導電銷400的側緣，藉此使得其中一組裝端子200在相對應的導電銷400上之施力方向與另一組裝端子200在相對應的另一導電銷400上之施力方向不平行。The arrangement of the plurality of conductive pins 400 and the assembly terminals 200 can also achieve the effect of positioning, which is described in detail below. The force application direction of one assembly terminal 200 on the corresponding conductive pin 400 is not parallel to the force application direction of the other assembly terminal 200 on the corresponding other conductive pin 400 . Thereby, the lateral displacement of the shielding metal cover 300 along each conductive pin 400 can be avoided. Specifically, in the voltage conversion device of the present invention, the conductive pins 400 are flat, and the normal directions of the conductive pins 400 are not parallel to each other. Each tool respectively clamps the side edge of the corresponding conductive pin 400, so that the force direction of one assembly terminal 200 on the corresponding conductive pin 400 is in the direction of the other assembly terminal 200 on the corresponding other conductive pin 400. The direction of force application is not parallel.

於本實施例中，夾具220導電銷400時夾持各夾爪221分別施力於導電銷400的側緣。由於導電銷400呈扁平狀，藉此使得各夾爪221有較大的彈性變量以增加夾持力強度。In this embodiment, when the clamp 220 clamps the conductive pin 400 , each clamping jaw 221 exerts force on the side edge of the conductive pin 400 respectively. Due to the flat shape of the conductive pin 400 , each clamping jaw 221 has a larger elastic variable to increase the strength of the clamping force.

參閱圖7至圖8所示本發明的第二實施例，本實施例提供了組裝端子200的另一種實施方式。其組裝端子200具有一底座210以及一夾具220，底座210為立設於電路板100且圍繞穿孔103的筒體，底座210的底部延伸出一焊腳211且焊腳211焊接於電路板100。夾具220包含有自底座210的內壁向底座210之內延伸出相向配置的一對夾爪221，對應組裝端子200的導電銷400穿入底座210之內且被夾爪221夾持。再者，各夾爪221分別形成朝向穿孔103且相對於電路板100傾斜配置的一導引斜面222。當導電銷400***夾具220時，導引斜面222能夠引導導電銷400而易於***夾具220。本實施例的夾具220其設置在夾爪221筒狀的底座內而能夠避免導電銷400***夾具220時造成夾具220偏斜。Referring to the second embodiment of the present invention shown in FIG. 7 to FIG. 8 , this embodiment provides another implementation manner of the assembled terminal 200 . The assembly terminal 200 has a base 210 and a clamp 220 . The base 210 is a cylindrical body standing on the circuit board 100 and surrounding the through hole 103 . The clamp 220 includes a pair of opposing jaws 221 extending from the inner wall of the base 210 toward the base 210 . The conductive pin 400 corresponding to the assembly terminal 200 penetrates into the base 210 and is clamped by the jaws 221 . Furthermore, each clamping claw 221 respectively forms a guiding slope 222 facing the through hole 103 and obliquely disposed relative to the circuit board 100 . When the conductive pin 400 is inserted into the clamp 220 , the guiding slope 222 can guide the conductive pin 400 to be easily inserted into the clamp 220 . The clamp 220 of this embodiment is disposed in the cylindrical base of the jaw 221 to prevent the clamp 220 from being deflected when the conductive pin 400 is inserted into the clamp 220 .

參閱圖9至圖11所示本發明的第三實施例，本實施例提供了組裝端子200的又另一種實施方式。其組裝端子200具有立設於電路板100的一底座210及一夾具220，底座210的底部延伸出一焊腳211且焊腳211焊接於電路板100。夾具220包含有自底座210的一側延伸出一夾爪221，夾爪221的末端反轉朝向底座210，且對應組裝端子200的導電銷400被夾持於夾爪221及底座210之間。以最簡單的實施方式而言，單一夾爪221及可達到本實施之功效，本實施例不限定其夾爪221之數量。本實施例中較佳地設置有一對外形相鏡射的夾爪221，其各夾爪221之功效相同，藉此配置以增加對於導電銷400的夾持力並使夾爪221對於導電銷400的施力平均。再者，各夾爪221分別形成朝向穿孔103且相對於電路板100傾斜配置的一導引斜面222。當導電銷400***夾具220時，導引斜面222能夠引導導電銷400而易於***夾具220。Referring to the third embodiment of the present invention shown in FIGS. 9 to 11 , this embodiment provides yet another embodiment of the assembled terminal 200 . The assembly terminal 200 has a base 210 and a clamp 220 standing on the circuit board 100 , a soldering leg 211 extends from the bottom of the base 210 and the soldering leg 211 is soldered to the circuit board 100 . The clamp 220 includes a clamping claw 221 extending from one side of the base 210 . The end of the clamping claw 221 is reversed toward the base 210 , and the conductive pin 400 corresponding to the assembly terminal 200 is clamped between the clamping claw 221 and the base 210 . In the simplest embodiment, a single clamping jaw 221 can achieve the effect of this embodiment, and this embodiment does not limit the number of its clamping jaws 221 . In this embodiment, a pair of clamping jaws 221 that are mirrored in appearance are preferably provided, and the functions of each clamping jaw 221 are the same, so as to increase the clamping force for the conductive pin 400 and make the clamping jaws 221 more effective for the conductive pin 400 Average force. Furthermore, each clamping claw 221 respectively forms a guiding slope 222 facing the through hole 103 and obliquely disposed relative to the circuit board 100 . When the conductive pin 400 is inserted into the clamp 220 , the guiding slope 222 can guide the conductive pin 400 to be easily inserted into the clamp 220 .

於本實施例中，導電銷400被夾持於夾爪221及底座210之間。底座210為不可動，因此能夠定位導電銷400以避免導電銷400位移。In this embodiment, the conductive pin 400 is clamped between the jaw 221 and the base 210 . The base 210 is not movable, so the conductive pin 400 can be positioned to prevent the conductive pin 400 from being displaced.

本發明的電壓轉換裝置藉由扣接的方式組裝屏蔽金屬罩300而適用於自動化組裝，而且其他的電子元件也適用於錫爐自動化焊接，因此可全自動化組裝故其成本低廉。The voltage conversion device of the present invention is suitable for automatic assembly by assembling the shielding metal cover 300 in a snap-fit manner, and other electronic components are also suitable for automatic soldering in a tin furnace, so it can be assembled fully automatically and its cost is low.
