本案關於一種電連接器組，尤指一種充電用之USB TYPE-C之電連接器組。 This case relates to an electrical connector set, especially a USB TYPE-C electrical connector set for charging.

電連接器於現今社會中係廣泛地應用於電子設備中，以作為電源及訊號傳輸之介面。然隨著科技發展，為了因應不同種類、型態、廠牌的電子設備，各種規格、規範之電連接器隨之蓬勃發展。舉例來說，目前最常被大眾使用的主流連接介面即為通用序列匯流排(USB)連接器組，使用者可將具有USB公插頭的周邊裝置，如滑鼠、外接式硬碟、行動電源等，對應插至具有USB母插座之電子裝置上，藉以達成周邊裝置與墊子裝置之間的電連接，進而輸送電力及訊號，以使周邊裝置可分別產生各種不同的效用。 Electrical connectors are widely used in electronic equipment in today's society as an interface for power supply and signal transmission. However, with the development of science and technology, in order to cope with different types, types, and brands of electronic equipment, electrical connectors of various specifications and specifications are booming. For example, the mainstream connection interface most commonly used by the public is the Universal Serial Bus (USB) connector set. Users can connect peripheral devices with USB male plugs, such as mice, external hard drives, and mobile power supplies. etc. Correspondingly plugged into the electronic device with the USB female socket, so as to achieve the electrical connection between the peripheral device and the mat device, and then transmit power and signals, so that the peripheral devices can produce various effects respectively.

請參閱第3圖。第3圖為第2圖所示之第一接腳組及第二接腳組之組合結構示意圖。如圖所示，當本實施例之電連接器組1之插頭部3與插座部2對應連接時，插頭部3內的複數個連接端子321係上下對應夾持插座部2內的複數個接地端子221以及複數個訊號端子222。其中，由於連接端子321之第二接合部321g之彎曲部321d、321e均為弧形彎曲部，是以當其對應接觸接地端子221之第一接合部221g時，係可順應其弧形曲線而向前滑行推動，直至第二接合部321g之彎曲部321d、321e對應卡合定位於第一接合部221g之凹部221d、221e內，如此一來，透過此等波浪狀之彎曲部321d、321e及凹部221d、221e等結構，以增加連接端子321與接地端子221之接觸面積，使其可容受更大的充電電流值。 See Figure 3. FIG. 3 is a schematic diagram of the combined structure of the first pin group and the second pin group shown in FIG. 2 . As shown in the figure, when the plug part 3 of the electrical connector set 1 of the present embodiment is correspondingly connected with the socket part 2, the plurality of connection terminals 321 in the plug part 3 are correspondingly clamped up and down with a plurality of grounding terminals in the socket part 2. A terminal 221 and a plurality of signal terminals 222 . Wherein, since the curved portions 321d and 321e of the second bonding portion 321g of the connecting terminal 321 are both arc-shaped curved portions, when they correspond to the first bonding of the grounding terminal 221 221g, it can slide and push forward according to its arc shape until the curved parts 321d and 321e of the second joint part 321g are correspondingly engaged and positioned in the concave parts 221d and 221e of the first joint part 221g. In this way, The wavy curved portions 321d, 321e and recessed portions 221d, 221e increase the contact area between the connection terminal 321 and the ground terminal 221, so that it can withstand a larger charging current value.

以及，如第2圖及第3圖所示，由於本實施例之接地端子221係為高度增高之端子結構，是以每一接地端子221均被兩連接端子321對應上下夾持，意即其係同時被上排連接端子321a抵頂上表面221b、以及被下排連接端子321b抵頂下表面221c，透過此上下兩排連接端子321a、321b對應施加的抵頂應力以夾持接地端子221。且如前所述，當上排連接端子321a與接地端子221對應接合時，上排連接端子321a之第二接合部321g向下彎曲之彎曲部321d、321e係對應設置於接地端子221之上表面221b的凹部221d、221e內，並彼此對應接觸，且上排連接端子321a之第二連接部321f係平貼接觸接地端子221之第一連接部221f，以構成電連接。同樣地，下排連接端子321b之第二接合部321g向上彎曲之彎曲部321d、321e亦對應設置於接地端子221之下表面221c的凹部221d、221e內，並彼此對應接觸，且下排連接端子321b之第二連接部321f亦平貼接觸接地端子221之第一連接部221f，以構成電連接。如此一來，透過此相對應設計之波浪狀之第一接合部221g及第二接合部321g，可有效增加連接端子321b之端部321c與接地端子221之端部221a之接觸面積，意即本實施例之端子接觸方式為立體多面接觸之方式，進而可增加端子接觸面積，而不會如同習知技術中僅為單一平面接觸，使得其流經之電流值受限。 And, as shown in Fig. 2 and Fig. 3, since the ground terminal 221 of this embodiment is a terminal structure with increased height, each ground terminal 221 is clamped up and down by two connecting terminals 321 correspondingly, which means that its The upper surface 221b is pressed against the upper row of connecting terminals 321a and the lower surface 221c is pressed against the lower row of connecting terminals 321b at the same time, and the grounding terminal 221 is clamped through the corresponding abutting stress applied by the upper and lower rows of connecting terminals 321a and 321b. And as mentioned above, when the upper row of connecting terminals 321a and the grounding terminal 221 are engaged correspondingly, the bent portions 321d and 321e of the second connecting portion 321g of the upper row of connecting terminals 321a bent downward are correspondingly arranged on the upper surface of the grounding terminal 221 The recesses 221d and 221e of 221b are in corresponding contact with each other, and the second connection portion 321f of the upper row of connection terminals 321a is in flat contact with the first connection portion 221f of the ground terminal 221 to form an electrical connection. Similarly, the upwardly curved bent portions 321d and 321e of the second joint portion 321g of the lower row of connection terminals 321b are also correspondingly disposed in the recesses 221d and 221e of the lower surface 221c of the ground terminal 221, and contact each other correspondingly, and the lower row of connection terminals The second connection portion 321f of 321b is also in contact with the first connection portion 221f of the ground terminal 221 to form an electrical connection. In this way, through the correspondingly designed wave-shaped first joint portion 221g and second joint portion 321g, the contact area between the end portion 321c of the connection terminal 321b and the end portion 221a of the ground terminal 221 can be effectively increased, which means that the The terminal contact method of the embodiment is a three-dimensional multi-surface contact method, which can increase the contact area of the terminal, instead of only a single plane contact as in the conventional technology, so that the current value flowing through it is limited.
