Various standards and specifications have been proposed and implemented for electrical connectors that transmit high-frequency signals. One example is the four-channel small form-factor pluggable (QSFP), which is a specification for compact, hot-swappable transceivers typically used in data communication systems. The QSFP transceiver socket can accept both electrical and optical transceivers. Recently, a modification to QSFP called a double-density four-channel small form-factor pluggable device (QSFP-DD) has been proposed to include additional contact rows on the transceiver circuit board to increase the bandwidth.

圖9展示具有替代結構之屏蔽罩14。圖9中之屏蔽罩14包括彈簧21及保持閂鎖22,該保持閂鎖可將例如圖5中所展示之散熱器21的散熱器或其類似物固定至屏蔽罩14。彈簧21可為如圖9中所展示之S形板片彈簧,但亦可包括其他適合之彈簧及形狀。保持閂鎖22可防止散熱器自屏蔽罩14脫離。儘管保持閂鎖22在圖9中位於與邊框開口15相對之後部開口16中,但保持閂鎖22亦可位於較接近邊框開口15之開口16中。儘管保持閂鎖22在圖9中相對於後部開口16居中,但保持閂鎖22可側向偏移,以免居中於後部開口16中。
FIG. 9 shows the shielding
彈簧21可在製造屏蔽罩14時被衝壓成形。因此,屏蔽罩14及彈簧21可界定單體主體,亦即,界定單一整體結構。亦可提供屏蔽罩14及彈簧21之其他可能結構。舉例而言,屏蔽罩14可經衝壓,且接著彈簧21可隨後添加至屏蔽罩
14,其中彈簧21中之每一者延伸至屏蔽罩14之開口16中。
The
彈簧21中之每一者可在實質上相同之總體方向上自屏蔽罩14延伸。如圖9中所展示,屏蔽罩14可包括兩個開口16,且兩個彈簧21可延伸至開口16中之每一者中。圖9展示四個彈簧21,但可使用任何數目之彈簧,包括例如兩個彈簧,且可使用彈簧之任何配置,包括例如開口16中之一者中具有兩個彈簧而另一開口16中無彈簧,或該等開口16中之每一者中具有一個彈簧。亦有可能使用任何適合之數目、位置及結構的開口16。散熱器可在第一方向上滑動至屏蔽罩14上,且彈簧21可與該散熱器中之凹穴接合。隨後,除在與第一方向相反之方向上之外,彈簧21顯著減少或阻止散熱器在由開口16界定之平面中移動。
Each of the
如圖9中所展示,彈簧21延伸至屏蔽罩14之開口16中,且處於與彈簧21之附接至屏蔽罩14之部分相對的彈簧21之遠端的彈簧21之頂端包括接合部分,該等接合部分位於由開口16界定之平面內,其中該等彈簧21之剩餘部分位於由該等開口16界定之平面上方。如圖9中所展示,彈簧21可大體具有S形,其中該等彈簧21向後摺疊至其自身上,其中接合部分自S形之頂部向下朝向屏蔽罩14延伸。亦可提供其他適合之形狀及結構,包括例如取決於散熱器中之凹穴的大小及位置,彈簧21之頂端及接合部分位於由開口16界定之平面上方或下方。
As shown in FIG. 9, the
每一彈簧21可插入散熱器中之對應凹穴中以與該散熱器接合。彈簧21在散熱器上提供向下力以偏置散熱器以在收發器插入屏蔽罩14中時接觸收發器。彈簧21可自動地使散熱器相對於收發器偏置。彈簧21允許散熱器浮動且向上及向下行進。向上及向下行進之浮動散熱器可容納不同高度之收發器。散熱器無需將力施加於散熱器之頂表面、側表面或後表面上之彈簧或綁帶。屏蔽罩14上之彈簧21在散熱器內之凹穴上施加向下力。如圖9中所展示,屏蔽罩14可包括底部上之彈簧23,該等彈簧朝向屏蔽罩14之頂部向上推動浮動散熱器。屏蔽罩14之底部上的彈簧23可具有與屏蔽罩14之頂部上的彈簧21類似之偏轉範圍內的彈簧
力,此允許收發器與屏蔽罩14內之電連接器之開口對準且減小收發器在屏蔽罩連接器接點上之不對稱負載力。

如圖3、圖4、圖7及圖8中所展示,第一指形件32可各自在製造公差內具有相同長度或大致相同長度,而第二指形件32可具有不同長度。舉例而言,鄰近第二指形件32可具有不同長度。替代地,第一指形件32可具有不同長度,及/或第二指形件33可各自在製造公差內具有相同長度或大致相同長度,其中外指形件部分33a及內指形件部分33b兩者具有不同長度以容納交錯式通孔19。如圖1及圖2中所展示,外指形件部分33a可取決於第二指形件33延伸穿過之對應通孔19的位置而具有不同長度。如圖3中所展示,內指形件部分33b可在製造公差內具有相同長度或大致相同長度。因此,第二指形件33之總長度可不同。
As shown in FIGS. 3, 4, 7 and 8, the
第一指形件32及第二指形件33中之每一者可具有不同長度及/或寬度。舉例而言,鄰近第一指形件32可具有不同長度及/或寬度,且鄰近第二指形件33可具有不同長度及/或寬度。然而,所有第一指形件32及/或所有第二指形件33可具有相同長度及/或寬度。第二指形件33之寬度係以對應於通孔19之第一圖案與第二圖案之組合的圖案提供。舉例而言,第二指形件33之寬度可具有小、大、大、小之圖案。
Each of the
第二指形件33中之每一者包括連接外指形件部分33a與內指形件部分33b且允許該等第二指形件33延伸穿過通孔19之彎曲部。第二指形件33之鄰近指形件可具有位於沿第二指形件之不同長度處之彎曲部。第二指形件33之彎曲部之圖案可交替。舉例而言,第二指形件33之彎曲部可在較接近邊框開口15與
較遠離邊框開口15之間交替。若包括通孔19之多於兩個列19a、19b,則可提供彎曲部之多於兩個位置。彎曲部之位置可交錯,使得鄰近彎曲部具有不同位置。第二指形件可包括彼此緊鄰之三個指形件,其中兩個彎曲部處於同一位置,且另一彎曲部處於不同位置。
Each of the
第二指形件33顯著地長於第一指形件32。另外,第二指形件33穿過屏蔽罩14中之通孔19,且因此包括沿屏蔽罩14之外表面定位的外指形件部分33a及與第一指形件32位於屏蔽罩14之相同內表面上的內指形件部分33b。儘管屏蔽罩14中之通孔19可潛在地提供EMI發射之位置,但穿過通孔19,以界定第二指形件33之內指形件部分33b及外指形件部分33a的第二指形件33提供了用於通孔19之EMI屏蔽。
The
在圖3之左側上,通孔19包括於通孔19之第二列19b中,該第二列較遠離邊框開口15,而在圖3之右側上,通孔19包括於通孔19之第一列19a中,該第一列最接近於該邊框開口15。在圖4之左側及右側兩者上,通孔19包括於通孔19之第一列19a中,該第一列最接近於邊框開口15。第一指形件32可沿屏蔽罩14之內表面延伸至通孔19之第一列19a,而不延伸至通孔19之第二列19b。延伸至第一列19a之第一指形件32可經配置而使得在收發器插入至屏蔽罩14中時,彼等第一指形件32與延伸穿過第一列19a中之通孔19的第二指形件33接觸。第一指形件32亦可經配置而使得當收發器插入至屏蔽罩14中時,第一指形件32不與第二指形件33接觸。

第一指形件32及第二指形件33之指形件可在其各別長度之一部分上藉由氣隙實體上彼此分離、可僅在一端處懸置且可在一端處實體地或電連接在一起。第一指形件32及第二指形件33之指形件可僅包括一個各別自由端。邊框夾31可藉由包括焊接、過盈配合連接及其類似者之任何適合連接固定至屏蔽罩14。內指形件部分33b可與屏蔽罩14之邊框開口15間隔開且與第一指形件32間
隔開,其中該等內指形件部分33b僅實體地觸碰電連接器或收發器之導電外表面,且不實體地觸碰裝置100之面板壁。
The fingers of the
邊框夾31可由任何適合之導電材料製成,且可藉由任何適合之方法製成。舉例而言,邊框夾31可由衝壓金屬製成。邊框夾31可使用包括例如凹口34之任何適合之方法安裝至屏蔽罩14。
The
第一指形件32中之每一者、第二指形件33之外指形件部分33a及第二指形件33之內指形件部分33b可包括提供壓配機械連接及電連接之凸起表面(例如,「凸塊」)。更特定言之,外指形件部分33a之凸起表面提供自EMI邊框至包括收發器插座10之裝置100的機殼接地101之機械及電連接。當收發器插入至收發器插座10之屏蔽罩14中時,第一指形件32及內指形件部分33b兩者均接觸該收發器。因此,歸因於由內指形件部分33b提供之額外接觸點,當與其他已知插座相比較時,與收發器接觸之邊框指形件接觸點的總數目能夠例如增加約兩倍。當與其他已知插座相比較時,與收發器接觸之邊框指形件接觸點之總數目的此增加亦會使屏蔽罩14之接地連接的串聯阻抗減小約50%或更多。一種減少不合需要之EMI發射的方法可包括藉由在邊框夾31與匹配連接器或收發器之間添加實體及電接觸(例如與匹配連接器或收發器之導電外表面之實體及電接觸)的點來減小屏蔽罩14、邊框夾31與匹配連接器或收發器之間的接地連接之串聯阻抗。另一方法可包括藉由在屏蔽罩14之邊框夾31與匹配連接器或收發器之間添加實體及電接觸的點(例如與匹配連接器或收發器之導電外表面之實體及電接觸的點)來減少自屏蔽罩14之EMI發射。
Each of the
另外,內指形件部分33b位於包括收發器插座10之裝置100的內部中,即在朝向屏蔽罩14之後壁的方向上位於收發器插座10之邊框開口15後。因此,在收發器內產生的EMI能夠藉由短的電路逕自第二指形件33、經過屏蔽罩14之通孔19投送至外指形件部分33a之凸起表面與裝置100之機殼接地101之間的
接地連接。此外,由於接地路徑在裝置100內之內指形件部分33b處開始,而非在裝置100外部的邊框開口15內開始,因此帶有邊框夾31之收發器插座10在收發器插座10為空及收發器插座10與收發器配合時皆能夠顯著減少EMI發射。換言之,一種方法包括在EMI場到達收納邊框夾31之外指形件部分33a或第一指形件32之面板中的開口之前將由收發器或其他匹配電連接器產生的不合需要之EMI場短接至接地。此外,當收發器插座10與收發器配合時,第一指形件32及第二指形件33與收發器之間的增加數目之接觸點顯著改良連接器60之散熱,此亦有助於減少EMI發射。一種方法可包括藉由增加邊框夾31之第一指形件32及第二指形件33與例如收發器或其他匹配連接器之熱源之間的接觸點之數目來使連接器散熱。
In addition, the
當與先前技術相比時,圖5中所展示之收發器插座10提供在約8GHz至約14GHz之頻率範圍內顯著改良之屏蔽效能,而當與雜訊底限相比時,該收發器插座提供在約4GHz至約14GHz之頻率範圍內更好的屏蔽效果。
When compared with the prior art, the
如上文所描述,當收發器插入至收發器插座10之屏蔽罩14中時,第一指形件32及內指形件部分33b兩者接觸收發器,藉此提供多個接地路徑以減小屏蔽罩14、邊框夾31與匹配連接器或收發器之間的接地連接的串聯阻抗。因此,圖5中所展示之收發器插座10提供在約500MHz至約4GHz之頻帶中且在約14GHz至約20GHz之頻帶中非常接近於雜訊底限之屏蔽效能。屏蔽效能或屏蔽效果係指共模能量之電力傳遞之緩解。另外,上述頻帶中之屏蔽效能可例如藉由包括前置放大器而進一步提高。總體而言,圖5中所展示之收發器插座10能夠將動態範圍增大約10dB,該動態範圍隨後可在實施前置放大器及自動獲取時進一步增大至約35dB至約45dB。
As described above, when the transceiver is inserted into the
本創作之實施方式之收發器插座10,且更具體言之為屏蔽罩14及邊框夾31,即使在散熱器被移除且更換四次之後也可提供恆定的屏蔽效果。因此,除提供較高屏蔽效果外,根據本創作之實施方式的收發器插座亦為耐用且可
靠的。
