Rear end cover assembly, manufacturing mold, and connector

Abstract

The present invention discloses a rear end cover assembly, a manufacturing mold, and a connector that can improve manufacturing efficiency and enhance sealing performance. [Solution] The rear end cover assembly comprises an end wall and a peripheral wall, a rear end cover (1), and a sealing element (3) formed by sealant (3') injected into the internal cavity of the rear end cover (1). A slot hole for the connector cable is formed in the end wall, and a cable through-hole for the cable is formed in the sealing element (3), and the cable through-hole is suitable for crimping with the cable to achieve a seal between the cable through-hole and the cable. Before injecting the sealant (3'), the rear end cover (1) is fixed to a manufacturing mold (2) with its opening facing upward, and a pin (22) of the manufacturing mold (2) extends into the internal cavity of the rear end cover (1) through the slot hole to form the cable through-hole.
