IEC 61076-3-117:2009标准规定了用于工业环境中的8路屏蔽和非屏蔽连接器的保护外壳的详细规范。该标准适用于采用IEC 60603-7系列接口的第14个变种的连接器，该连接器采用推拉式耦合。该标准的目的是确保连接器在工业环境中的可靠性和耐用性。

该标准规定了连接器保护外壳的尺寸、材料、颜色、标识、安装方式等要求。保护外壳应该能够保护连接器免受机械损坏、化学腐蚀、电磁干扰等影响。保护外壳应该具有防水、防尘、防腐蚀等性能，以确保连接器在恶劣环境下的可靠性。

此外，该标准还规定了连接器保护外壳的电气性能要求。保护外壳应该具有良好的屏蔽性能，以防止电磁干扰对连接器的影响。保护外壳应该能够承受一定的电压和电流，以确保连接器的安全性和可靠性。

IEC 61076-3-117:2009标准的实施可以提高连接器在工业环境中的可靠性和耐用性，保护外壳的设计和制造符合该标准的要求，可以确保连接器在恶劣环境下的正常工作。
