Abstract

L'invention concerne une douille comprenant une coque externe de douille et au moins une pince de serrage de câble. La coque externe de douille comprend au moins un connecteur femelle, l'au moins un connecteur femelle étant un connecteur femelle à cinq trous, un connecteur femelle à deux trous ou un connecteur femelle à trois trous. L'au moins une pince de serrage de câble est disposée sur la coque externe de douille et coopère avec celle-ci pour former un trou de serrage de câble. Lorsqu'un connecteur mâle est branché dans l'au moins un connecteur femelle, le trou de serrage de câble est conçu pour permettre à un câble d'alimentation du connecteur mâle de passer à travers, de manière à limiter le mouvement d'un segment de câble d'alimentation entre le connecteur mâle et le trou de serrage de câble par rapport à la douille.
