Electrical connector assembly with separate arcing zones

一种电气连接器组件，它包括一个保持刀形触头(16)的绝缘刀形连接器外壳，一个保持插座触头(18)的绝缘插座连接器外壳。刀形和插座连接器外壳在配合操作过程中连接，在该配合操作过程中，刀形和插座触头从一个初始配合位置移动到一个最终配合位置。刀形和插座触头具有配合部(54，124)，当所述刀形和插座触头处在所述最终位置时，所述配合部相互电接合。配合部在所述刀形和插座触头之间具有一个主要电接触面。所述刀形和插座触头还具有各自的电弧区(62，148)，当所述刀形和插座触头处在所述最初配合位置时所述电弧区可以相互暂时电接通，以便在所述刀形和插座触头之间提供一个临时电接触面。 An electrical contact assembly is provided that includes insolated blade and receptacle connector housings mateable with one another while moved from initial to final mating positions. A blade contact is provided with a support section that is securely mounted within the insulated connector housing. The blade contact further includes a contact knife projecting from the support section. A receptacle contact is provided having a base section that is securely mounted in the insulated receptacle housing. Arcing zones are defined on the blade and receptacle contacts that are located separate and apart from mating zones. The arcing zones electrically engage one another only when the blade and receptacle contacts are located in the initial mating position to provide a temporary electrical interface for discharging arcs between the blade and receptacle contacts. After which, the arcing zones disengage one another.
