It should be understood that the present invention can have various variations in different aspects, but they all do not deviate from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustrative purposes rather than for limiting the present invention.
請參閱第1A圖至第1C圖，第1A圖顯示根據本案第一較佳實施例之電連接器的示意圖，第1B圖顯示根據本案第一較佳實施例之電連接器中絕緣體與複數個端子的透視圖，以及第1C圖顯示第1A圖之電連接器的底視圖。電連接器1包含殼體11、絕緣體12、及複數個端子，其中殼體11用以容置絕緣體12及複數個端子，絕緣體12包含舌部121及基部122，以及複數個端子包含複數個接地端子13、複數個電源端子14、及複數個訊號端子15，例如，包含4個接地端子13、4個電源端子14、及8個訊號端子15，且每一該複數個接地端子13具有第一接觸部131、第二接觸部132、及連接第一接觸部131與第二接觸部132的連接部133，每一該複數個電源端子14具有第一接觸部141、第二接觸部142、及連接第一接觸部141與第二接觸部142的連接部143，以及每一該複數個訊號端子15具有第一接觸部151、第二接觸部152，及連接第一接觸部151與第二接觸部152的連接部153。Please refer to Figures 1A to 1C, Figure 1A shows a schematic diagram of an electrical connector according to the first preferred embodiment of the present case, Figure 1B shows a perspective view of an insulator and multiple terminals in the electrical connector according to the first preferred embodiment of the present case, and Figure 1C shows a bottom view of the electrical connector of Figure 1A. The
殼體11具有前端A及後端B。前端A為一套筒狀結構，且舌部121設置於其中，以接收相對應的電連接器；後端B用以與一裝置（未顯示，例如手機、平板電腦等）形成電連接。複數個端子的複數個第一接觸部係設置於舌部121的表面，以與所接收之相對應電連接器中的端子形成電連接，以及複數個端子之複數個第二接觸部係自基部122延伸而出，並於後端B電連接至設置於裝置內的電路板（未顯示）。亦即，前端A為電連接器1的插接端，且後端B為電連接器1的電路板連接端。The
在此，為清楚描述，係進一步定義平行前端A至後端B之方向為電連接器1的縱向方向，以及與縱向方向垂直之方向為電連接器1的橫向方向，且定義沿縱向方向之尺寸變化為長度變化，以及沿橫向方向之尺寸變化為寬度變化。Here, for the sake of clear description, the direction parallel to the front end A to the rear end B is further defined as the longitudinal direction of the
舌部121為一平板結構，且平板結構之平面以平行於電連接器1之橫向方向設置於殼體11內，複數個端子的第一接觸部131、141、151係於平板結構的上下表面以橫向方向排列，故第一接觸部131、141、151亦位於前端A中。第一接觸部於舌部121之上表面及下表面上係以相同的方式排列，其中訊號端子15之第一接觸部151位於中間，第一接觸部151兩側各鄰接電源端子14之第一接觸部141，各第一接觸部141的另一側則再鄰接接地端子13之第一接觸部131。換言之，本案之電連接器1是一種可接收正反雙向插接、無方向性的電連接器，例如，USB Type C連接器。The tongue 121 is a flat plate structure, and the plane of the flat plate structure is arranged in the
為了提升電連接器1的額定電流，本案係透過變化接地端子13及電源端子14的尺寸及結構來達成。如第1B圖及第1C圖所示，接地端子13、電源端子14及訊號端子15分別位於舌部121之表面的第一接觸部131、141、151於橫向方向的寬度係彼此大致相等，而不同種類端子於後端B的第二接觸部於橫向方向的寬度則彼此不同。其中，訊號端子15之第二接觸部152的寬度W1，維持為與第一接觸部151的寬度相近，另一方面，接地端子13之第二接觸部132的寬度W2及電源端子14之第二接觸部142的寬度W3則較各自之第一接觸部131、141的寬度增加，換言之，接地端子13及電源端子14分別之第二接觸部132、142的寬度W2及W3皆大於訊號端子15之第二接觸部152的寬度W1。據此，在本實施例中，接地端子13及電源端子14是透過增加第二接觸部132、142於橫向方向之寬度的方式來達到提升額定電流的目的。In order to increase the rated current of the
接地端子13及電源端子14的寬度變化方式是，第一接觸部131、141的寬度維持不變，例如，與通用規格電連接器之端子的寬度一致，並自連接部133、143開始產生寬度變化。舉例而言，如第1B圖所示，接地端子13及電源端子14可在連接部133、143與第一接觸部131、141相接處開始逐漸增加寬度，並在增加至所需寬度後維持寬度，且繼續延伸至第二接觸部132、142，但不受限制於此。第二接觸部132、142之寬度W2及寬度W3的範圍可視實際需求而定，且寬度W2與寬度W3可為相同或不同，亦不受限制。The width of the ground terminal 13 and the power terminal 14 is changed in such a way that the width of the first contact portions 131 and 141 remains unchanged, for example, consistent with the width of the terminal of the general specification electrical connector, and the width changes from the connecting portions 133 and 143. For example, as shown in FIG. 1B , the ground terminal 13 and the power terminal 14 can gradually increase the width at the junction of the connecting portions 133 and 143 and the first contact portions 131 and 141, and maintain the width after increasing to the required width, and continue to extend to the second contact portions 132 and 142, but are not limited thereto. The ranges of the width W2 and the width W3 of the second contact portions 132 and 142 may be determined according to actual needs, and the width W2 and the width W3 may be the same or different, and are not limited thereto.
當接地端子13及電源端子14之寬度增加時，係有利於大電流通過，尤其寬度自連接部133、143即開始逐漸增加，並持續維持至第二接觸部132、142，故除了可供更大的電流通過外，如此之加寬端子設計亦有助於散熱並減少溫度的上升。綜合起來，可有效符合利用電連接器進行快速充電的應用需求。When the width of the ground terminal 13 and the power terminal 14 increases, it is conducive to the passage of large currents, especially the width gradually increases from the connecting parts 133 and 143 and continues to be maintained to the second contact parts 132 and 142. Therefore, in addition to allowing a larger current to pass, such a widened terminal design also helps to dissipate heat and reduce the temperature rise. In summary, it can effectively meet the application requirements of using electrical connectors for fast charging.
為了容置尺寸加大的接地端子13及電源端子14，尤其是第二接觸部132、142，殼體11之外觀尺寸及形狀係因應地有所變化。在第1A圖至第1C圖所示之實施例中，殼體11進一步於縱向方向分為第一區段111及第二區段112，第一區段111位於電連接器1的前端A，第二區段112位於電連接器1的後端B，且第二區段112於橫向方向的寬度L2大於第一區段111於橫向方向的寬度L3。也就是，電連接器1於縱向方向的長度L1及第一區段111於橫向方向的寬度L3皆維持不變，例如，與通用規格電連接器之長度及寬度一致，只將第二區段112於橫向方向的寬度L2增加為較通用規格電連接器更寬。由於相較於未加寬第二接觸部的情形，在此實施例中，共有8個端子（4個接地端子13及4個電源端子14）之第二接觸部132、142寬度增加，故在以橫向方向排列、且需維持各端子間不相互干擾的前提下，排列成一排之第二接觸部132、142、152係需要更大的空間，據此，殼體11之第二區段112的寬度L2係實施為大於第一區段111的寬度L3，以提供更大的空間設置所有端子的第二接觸部132、142、152。換言之，相較於通用規格不具加寬端子的電連接器，在本實施例中，位於後端B的第二區段112與位於前端A的第一區段111間係形成結構斷差，使殼體外觀具有類似T字的形狀。In order to accommodate the enlarged ground terminal 13 and power terminal 14, especially the second contact portions 132 and 142, the outer dimensions and shape of the
第二區段112的寬度L2係取決於接地端子13及電源端子14分別之第二接觸部132、142的寬度，以及各接觸部之間的間距。更具體而言，接地端子13之第二接觸部132的寬度W2、電源端子14之第二接觸部142的寬度W3、訊號端子15之第二接觸部152的寬度W1、第二接觸部132與第二接觸部142間之間距D2、第二接觸部142與第二接觸部152間之間距D3、以及兩個第二接觸部152間之間距D1，係共同決定了殼體11之第二區段112於橫向方向上的寬度L2。換言之，當各第二接觸部分別的寬度及各第二接觸部間之間距發生變化時，第二區段112之寬度L2亦會隨之變化，以作為因應。The width L2 of the second section 112 depends on the widths of the second contact portions 132 and 142 of the ground terminal 13 and the power terminal 14, respectively, and the distance between the contact portions. More specifically, the width W2 of the second contact portion 132 of the ground terminal 13, the width W3 of the second contact portion 142 of the power terminal 14, the width W1 of the second contact portion 152 of the
另，第一區段111於縱向方向的長度L4及第二區段112於縱向方向的長度L5係主要取決於接地端子13及電源端子14之連接部133、143開始增加寬度的位置，故只需可提供各個端子合理配置空間即可，此兩區段分別之長度無特別的限制。再者，間距D1、D2、D3同樣可依實際需求而變化，例如，可實施為D1、D2、D3大致相等，或D2與D3大於D1及/或D2與D3兩者不相等，只需達到端子間不產生相互干擾且符合生產製程需求即可，不受限制。In addition, the length L4 of the first section 111 in the longitudinal direction and the length L5 of the second section 112 in the longitudinal direction are mainly determined by the position where the connection parts 133 and 143 of the ground terminal 13 and the power terminal 14 start to increase in width, so it is sufficient to provide reasonable configuration space for each terminal, and there is no special restriction on the lengths of the two sections. Furthermore, the spacings D1, D2, and D3 can also be changed according to actual needs. For example, it can be implemented that D1, D2, and D3 are roughly equal, or D2 and D3 are greater than D1 and/or D2 and D3 are not equal. It is sufficient to achieve no mutual interference between the terminals and meet the production process requirements, and there is no restriction.
是以，藉由接地端子13及電源端子14分別自連接部133、143起逐漸增加的寬度，可達到傳輸更大電流的效果，同時亦可增加接地端子13及電源端子14與電路板的接觸面積（亦即第二接觸部132、142的面積），進一步幫助散熱、降低溫升、並提升額定電流。另一方面，由於電連接器1係為接收插接相對應電連接器的母端，通常設置於裝置內，例如手機、平板電腦內，故只需透過規劃裝置內空間的方式即可順利置入具於橫向方向相對於通用規格電連接器增加寬度之第二區段112的殼體11。此外，各端子之第一接觸部的寬度係維持不變，亦即，位於前端A之插接端結構仍維持符合通用規格，與相對應連接器間的插接及電連接不受影響。Therefore, by gradually increasing the width of the ground terminal 13 and the power terminal 14 from the connection parts 133 and 143, respectively, the effect of transmitting a larger current can be achieved, and at the same time, the contact area between the ground terminal 13 and the power terminal 14 and the circuit board (that is, the area of the second contact parts 132 and 142) can be increased, further helping to dissipate heat, reduce temperature rise, and increase the rated current. On the other hand, since the

The electrical connector 1' comprises a housing 11', an insulator 12' and a plurality of terminals, wherein the housing 11' is used to accommodate the insulator 12' and the plurality of terminals, the insulator 12' comprises a tongue 121' and a base 122', and the plurality of terminals comprises a plurality of
殼體11’具有前端A’及後端B’。前端A’用以接收相對應的電連接器，且舌部121’設置於其中；後端B’用以與裝置（未顯示，例如手機、平板電腦等）形成電連接。複數個端子的複數個第一接觸部係設置於舌部121’的表面，以與所接收之相對應電連接器中的端子形成電連接，以及複數個端子之複數個第二接觸部係自基部122’延伸而出，並於後端B’電連接至設置於裝置內的電路板（未顯示）。亦即，前端A’為電連接器1’的插接端，且後端B’為電連接器1’的電路板連接端。The housing 11' has a front end A' and a rear end B'. The front end A' is used to receive the corresponding electrical connector, and the tongue 121' is disposed therein; the rear end B' is used to form an electrical connection with a device (not shown, such as a mobile phone, a tablet computer, etc.). A plurality of first contact portions of a plurality of terminals are disposed on the surface of the tongue 121' to form an electrical connection with the terminals in the received corresponding electrical connector, and a plurality of second contact portions of a plurality of terminals extend from the base 122' and are electrically connected to a circuit board (not shown) disposed in the device at the rear end B'. That is, the front end A' is the plug-in end of the electrical connector 1', and the rear end B' is the circuit board connection end of the electrical connector 1'.
在此，為清楚描述，同樣定義平行前端A’至後端B’的方向為電連接器1’的縱向方向，以及與縱向方向垂直之方向為電連接器1’的橫向方向，且定義沿縱向方向之尺寸變化為長度變化，以及沿橫向方向之尺寸變化為寬度變化。Here, for the sake of clear description, the direction parallel to the front end A' to the rear end B' is also defined as the longitudinal direction of the electrical connector 1', and the direction perpendicular to the longitudinal direction is defined as the transverse direction of the electrical connector 1', and the dimensional change along the longitudinal direction is defined as the length change, and the dimensional change along the transverse direction is defined as the width change.
其中，訊號端子15’之第二接觸部152’於橫向方向的寬度W1’維持為與第一接觸部151’的寬度相近，另一方面，為了提升額定電流，接地端子13a’、13b’及電源端子14a’、14b’於橫向方向之寬度皆自連接部133a’、133b’ 、143a’ 、143b’開始增加，以使第二接觸部132a’、132b’的寬度W2’及第二接觸部142a’、142b’的寬度W3’大於分別其第一接觸部的寬度。其他結構細節則與第1A-1C圖所示之實施例相同，即不再贅述。Among them, the width W1' of the second contact portion 152' of the signal terminal 15' in the lateral direction is maintained to be similar to the width of the first contact portion 151'. On the other hand, in order to increase the rated current, the widths of the
在此實施例中，為了容置尺寸加大的接地端子13a’、13b’及電源端子14a’、14b’，尤其是加寬的第二接觸部132a’、132b’、142a’、142b’，殼體11’之外觀尺寸及形狀亦進一步加以變化。而與第1A-1C圖所示實施例不同的是，殼體11’係透過增加縱向方向的長度L1’作為因應。如第2B圖及第2C圖所示，於殼體11’之後端B’，與訊號端子15’一起於橫向方向設置者，係為接地端子13a’ 的第二接觸部132a’及電源端子14a’的第二接觸部142a’，而接地端子13b’的第二接觸部132b’及電源端子14b’的第二接觸部142b’，則設置為於橫向方向的另一排，例如，排列於更接近前端A’的位置。也就是，接地端子13a’、13b’的第二接觸部132a’及132b’係以縱向方向排列，以及電源端子14a’、14b’的第二接觸部142a’及142b’亦以縱向方向排列。據此，電連接器1’的長度L1’係對應地加長，例如，較通用規格電連接器之縱向方向長度更長，也較第1A-1C圖所示實施例中之長度L1更長，而殼體11’之後端B’的寬度L2’則維持為與前端A’的寬度L3’大致一樣。In this embodiment, in order to accommodate the
在此，電連接器1’之長度L1’係取決於接地端子13b’之第二接觸部132b’於縱向方向的長度L6’及電源端子14b’之第二接觸部142b’於縱向方向的長度L7’，以及第二接觸部132a’與132b’間及第二接觸部142a’與142b’間分別的間距D4’。另，由於第二接觸部132b’ 及142b’移為單獨的一排，故即使在第二接觸部132a’及142a’之寬度加寬的情形下，殼體11’之後端B’於橫向方向的寬度L2’可維持大致相等於殼體11’之前端A’於橫向方向的寬度L3’，亦即與通用規格電連接器之橫向方向寬度大致相等。Here, the length L1’ of the electrical connector 1’ is determined by the length L6’ of the second contact portion 132b’ of the ground terminal 13b’ in the longitudinal direction and the length L7’ of the second contact portion 142b’ of the power terminal 14b’ in the longitudinal direction, as well as the distance D4’ between the second contact portions 132a’ and 132b’ and between the second contact portions 142a’ and 142b’, respectively. In addition, since the second contact portions 132b’ and 142b’ are moved to a separate row, even when the width of the second contact portions 132a’ and 142a’ is widened, the width L2’ of the rear end B’ of the shell 11’ in the lateral direction can be maintained to be approximately equal to the width L3’ of the front end A’ of the shell 11’ in the lateral direction, that is, approximately equal to the lateral width of a universal specification electrical connector.
在此，與前述相同，各端子之第二接觸部的寬度W1’、W2’、W3’及各端子之第二接觸部間的間距D1’、D2’、D3’、D4’的變化範圍，以及接地端子13b’之第二接觸部132b’的長度L6’及電源端子14b’之第二接觸部142b’的長度L7’的變化範圍，皆可視實際需求而定，只需達到各端子間不相互干擾，且符合生產製程需求，皆不受限制。Here, similar to the above, the width W1’, W2’, W3’ of the second contact portion of each terminal and the distance D1’, D2’, D3’, D4’ between the second contact portions of each terminal, as well as the length L6’ of the second contact portion 132b’ of the ground terminal 13b’ and the length L7’ of the second contact portion 142b’ of the power terminal 14b’ can all be determined according to actual needs. As long as the terminals do not interfere with each other and meet the production process requirements, there are no restrictions.
是以，藉由接地端子13a’、13b’及電源端子14a’、14b’分別自連接部133a’、133b’、143a’、143b’開始逐漸增加的寬度，可達到傳輸更大電流的效果，同時亦增加接地端子13a’、13b’及電源端子14a’、14b’與電路板的接觸面積（亦即第二接觸部132a’、132b’、142a’、142b’的面積），進一步幫助散熱、降低溫升、並提升額定電流。另一方面，由於電連接器1’係為接收插接相對應電連接器的母端，通常設置於裝置內，例如手機、平板電腦內，故只需透過規劃裝置內空間的方式即可順利置入於縱向方向之長度相對於通用規格電連接器增加的殼體11’。此外，各端子之第一接觸部的寬度係維持不變，亦即，位於前端A’之插接端結構仍維持符合通用規格，與相對應連接器間的插接及電連接不受影響。Therefore, by gradually increasing the width of the
更具體而言，本案的兩個實施例提供了兩種電連接器內第二接觸部之排列方式及相對應之殼體結構變化方式，以因應為了提升額定電流而加寬接地端子及電源端子之連接部及第二接觸部所增加的空間容置需求。藉由加寬之第二接觸部的排列配置與殼體之尺寸及形狀間的相互配合，可在相對於通用規格連接器不改變殼體之縱向方向長度下、亦可在相對於通用規格連接器不改變殼體之橫向方向寬度下達成容置需求，具優勢地提供可選擇性。進一步地，亦可相對於通用規格連接器同時增加殼體於縱向方向的長度及橫向方向的寬度，以因應對於接地端子及/或電源端子的其他加寬需求，不受限制。More specifically, the two embodiments of the present invention provide two arrangements of the second contact portion in the electrical connector and corresponding changes in the shell structure to meet the increased space accommodation requirements of the connection portion and the second contact portion of the ground terminal and the power terminal widened in order to increase the rated current. By coordinating the arrangement of the widened second contact portion with the size and shape of the shell, the accommodation requirements can be met without changing the longitudinal length of the shell relative to the universal specification connector, and without changing the lateral width of the shell relative to the universal specification connector, which advantageously provides selectivity. Furthermore, the length of the housing in the longitudinal direction and the width in the transverse direction can be increased at the same time compared to a connector of a general specification to meet other widening requirements for the ground terminal and/or the power terminal without restriction.
無論採用何種第二接觸部排列方式及相對應殼體結構變化方式，透過實驗數據可知，增加接地端子及電源端子之連接部及第二接觸部之寬度確實有助於提升額定電流。舉例而言，在一實施例中，採用寬度W1/W1’為0.2 mm，及寬度W2/W2’與寬度W3/W3’為0.7 mm的設計，亦即，寬度W2/W2’及W3/W3’約為寬度W1/W1’的3.5倍，再以溫升30度為基準，進行電流值測定，得出額定電流可達7A以上。此即表示透過本案接地端子與電源端子之寬度增加方式，確實有助於散熱、降低溫升、並提升額定電流。進一步地，寬度W2/W2’及W3/W3’與寬度W1/W1’之間亦可依實際需求而實施為不同的比例，例如加寬約3-5倍，故不受限於此。Regardless of the arrangement of the second contact portion and the corresponding change in the shell structure, experimental data show that increasing the width of the connection portion and the second contact portion of the ground terminal and the power terminal does help to increase the rated current. For example, in one embodiment, a design with a width of 0.2 mm for W1/W1' and a width of 0.7 mm for W2/W2' and W3/W3' is adopted, that is, the widths W2/W2' and W3/W3' are approximately 3.5 times the width of W1/W1', and the current value is measured based on a temperature rise of 30 degrees, and the rated current can reach more than 7A. This means that increasing the width of the ground terminal and the power terminal in this case does help to dissipate heat, reduce temperature rise, and increase the rated current. Furthermore, the widths W2/W2' and W3/W3' can be implemented in different ratios to the width W1/W1' according to actual needs, for example, the widths can be increased by about 3-5 times, and the present invention is not limited thereto.
綜上所述，本案之電連接器透過加寬接地端子及電源端子自連接部至第二接觸部於橫向方向的寬度，而可在達到傳輸大電流、提升額定電流之目的的同時，亦提供增加散熱、降低溫升的效果。再者，本案電連接器之外觀尺寸及形狀係進一步因應加寬的接地端子與電源端子的排列方式而可選擇地變化電路板連接端相對於通用規格電連接器於橫向方向的寬度及/或於縱向方向的長度，以在提供各加寬端子間不相互干擾的容置空間的前提下，亦維持插接端的結構符合通用規格。In summary, the electrical connector of the present invention can achieve the purpose of transmitting large current and increasing rated current by widening the width of the ground terminal and the power terminal from the connection part to the second contact part in the horizontal direction, while also providing the effect of increasing heat dissipation and reducing temperature rise. Furthermore, the appearance size and shape of the electrical connector of the present invention can further selectively change the width of the circuit board connection end in the horizontal direction and/or the length in the vertical direction relative to the general specification electrical connector in response to the arrangement of the widened ground terminal and the power terminal, so as to provide a non-interfering accommodation space between the widened terminals and maintain the structure of the plug end in compliance with the general specification.
