A shield for spliced electrical connections includes a cover for T-tap electrical connections. In embodiments, the cover includes complementary halves designed to quickly and securely snap together when the halves are mated with each other to create a shield for a T-tap connection. Fully assembled, the shield provides sleeves that allow the cables being spliced to enter and/or exit the shield. Each of the sleeves is provided with an adhesive sealant that tightly seals the shield against contamination from the elements. Integrated with the cover are structural elements such as gussets that enhance the resistance of the shield to impact damage such as crushing. The shield may be molded from a polymer that, when cured, provides a rigid or semi-rigid cover that generally protects the t-tap connection from all types of environmental damage.

A water-resistant element, adapted to an opining, comprising a deformable body, a first plate and a second plate is provided. The first plate is disposed at and against a first side of the deformable body. The second plate is disposed at and against a second side of the deformable body. When the deformable body is disposed in the opening, a relative displacement between the first plate and the second plate is used to change a shape of the deformable body such that the deformable body closely fits the opening in order to block moisture from entering into the opening. In addition, an external connection wire module comprising the water-resistant element, an antenna box module comprising the external connection wire module and a method of fixing the water-resistant element at a housing are also provided.
