密封連接器:三大關鍵輕鬆掌握

 

密封連接器:三大關鍵輕鬆掌握

上一篇文章提及了什麼是密封和氣密連接器的概念?以及抗氧化抗腐蝕連接器的解決方案 (延伸閱讀>>立刻看)

 

這讓各位工程師或採購人員清楚明白,會選擇「密封型連接器」(Sealed Connector)是為了防止水氣、氣體或油污進入而引起的氧化或腐蝕,同時確保訊號傳輸不受干擾。

但即使選擇密封型連接器也還是有許多關鍵重點需要注意,今天我們將一一揭露並解析這些關鍵重點。

 

 

一、密封連接器斷開連接後的潛在風險

大多數密封式連接器(Sealed Connector)都是成對使用的。一旦被拆卸或是斷開連接,它們可能無法再提供原有的保護力,甚至可能會進一步削弱連接器接口的性能,導致失去選擇密封連接器的初衷。

 

密封連接器斷開連接後可能的潛在風險

 

即使密封式連接器在斷開連結後仍然保持密封的狀態,也會存在接觸損壞的高潛在風險,尤其是否能維持優異的防水功能?這誰都無法保證,這種情況可能導致面臨更大的成本損失。

 

因此佳楠精密電子貼心重點提醒:

  • 工程師或採購人員在挑選密封連接器時,一定要選擇「已配對」的連接器,才能確保正常運作。
  • 在終端產品運送途中產生的振動或是終端產品運作中產生的振動,都有可能導致連接器的斷接,需要進行反覆高度的測試。亦或是選擇更優異的密封材料或密封型態的產品。
    (延伸閱讀>>什麼是密封和氣密連接器?抗氧化抗腐蝕連接器解決方案)
  • 若大量購買sealed connectors(密封連接器),需要存放在無濕氣和控溫的環境中,並定期檢查連接器的狀態。

 

以上建議有助於確保密封連接器的正常運作,並提供了更優的儲存和使用方式,以減少損壞與成本損失的風險。

 

 

二、密封連接器 Sealed Connectors 的材質該精挑細選

許多採購人員和工程師都保有迷思,認為選擇堅固的不銹鋼外殼之密封式連接器,具有防腐蝕和防污染的特性,就一定對產品比較好!

這聽起來確實很吸引人,但不幸的是,這並不適用於所有行業,特別是對運輸行業來說,每輛車子能夠承載的重量都是有限的。

 

隨著車輛負載的增加,所需的燃料和能源也會大幅增多,進而導致更高的耗損成本。因此在選擇密封連接器時,輕量化材料就是重要考量因素。

 

除此之外,材料的耐用性和成本也是關鍵因素。根據應用場景和客戶要求,佳楠精密電子能提供最佳的解決方案與諮詢,完整並完美達成您的需求

 

 

三、密封型連接器的介面選擇與產業應用

密封型連接器是為了保護設備防止液體或氣體進入,進而避免氧化和腐蝕,確保訊號傳輸的穩定性和可靠性,因此密封連接器非常適合在室外和惡劣的環境中使用,例如:

  • 潮濕多雨的環境:防止雨水或其他液體滲入,造成連接器損壞或腐蝕。
  • 粉塵瀰漫的環境:防止灰塵進入,造成接觸不良或影響訊號傳輸。
  • 腐蝕性環境:抵抗酸、鹼、鹽等腐蝕性物質的侵蝕。

 

除了防水連接器、氣密連接器之外,還有部分密封同軸連接器具有防油的功能,可應用於相關環境,例如:石油和天然氣工業、食品工業、化學工業,其防油功能就成為連接器選擇的關鍵考量因素。

 

最後,密封連接器根據密封位置的不同,還可分為以下四種密封型態:

  • 內密封:在連接器的內部進行密封,防止液體或氣體由連接器內部進入。
  • 面板密封:在連接器的面板處進行密封,防止液體或氣體由連接器外部進入。
  • 插配密封:在連接器的插配處進行密封,防止液體或氣體從連接器的插配處進入。
  • 完全密封:在內部、面板和插配處都進行密封,是密封性最完整的型態。

 

密封類型的比較表

 

介面種類繁多,以下是佳楠推薦的密封連接器類型:

  1. BNC介面連接器:50Ω(ohm)頻率範圍可達4 GHz,75Ω(ohm)可達1 GHz,廣泛應用於電腦網路、音頻、數據處理設備和電信設備。
