Abstract

Abstract A watertight type shielded connector includes a housing assembly and a terminal assembly. The housing assembly includes a housing and a shield element molded integrally with the housing. The terminal assembly includes a resilient plug fitted over the sheath of a shielding wire. The shielding wire has a distal end thereof connected to a terminal. The terminal assembly also includes a conductor in electrical contact with the shielding material of the shielding wire. Upon inserting the terminal assembly into the housing assembly, the conductor electrically engages the shield element of the housing assembly so that the conductor establishes electric continuity between the shield element of the housing assembly and the shielding material of the terminal assembly while at the same time the plug fits to the fitting bore of the housing assembly so that the terminal assembly engages the housing assembly in a watertight relation. The shield element of the housing assembly serves to shield the terminal. The plug is formed with a first projection extending all around the outer surface of the plug to form a closed loop and a second projection extending all around the inner surface of the plug to form a closed loop, the first projection fitting to the fitting bore of the housing assembly and the second projection fitting over the sheath of the shielding wire. The plug and conductor may take the form of a single component made of a conductive rubber.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 117 words
A shielded connector comprising: a housing assembly having a housing and a first shield element molded integrally with said housing; a terminal assembly including a plug fitted over a sheath of a shielding wire having a distal end thereof connected to a terminal, and a conductor in electrical contact with a second shield element of the shielding wire, wherein upon inserting said terminal assembly into said housing assembly, said conductor electrically engages said first shield element so that said conductor establishes electric continuity between said first shield element and said second shield element, and said plug fits to an inner wall of the housing so that said terminal assembly engages said housing assembly in a watertight relation.
Claim 2
Dependent Claim 117 words
A shielded connector comprising: a housing assembly having a housing and a first shield element molded integrally with said housing; a terminal assembly including a plug fitted over a sheath of a shielding wire having a distal end thereof connected to a terminal, and a conductor in electrical contact with a second shield element of the shielding wire, wherein upon inserting said terminal assembly into said housing assembly, said conductor electrically engages said first shield element so that said conductor establishes electric continuity between said first shield element and said second shield element, and said plug fits to an inner wall of the housing so that said terminal assembly engages said housing assembly in a watertight relation.
Claim 3
Dependent Claim 16 words
The shielded connector according to claim 1, wherein said plug is made of a resilient material.
Claim 4
Dependent Claim 75 words
The shielded connector according to claim 2, wherein said plug is formed with at least one first projection extending all around an outer surface thereof to form a closed loop and at least one second projection extending all around an inner surface thereof to form a closed loop, said first projection fitting to the inner wall of the housing of said housing assembly and said second projection fitting over the sheath of the shielding wire.
Claim 5
Dependent Claim 23 words
The shielded connector according to claim 3, wherein said conductor is of generally a pipe-like shape and fits over part of said plug.
Claim 6
Dependent Claim 48 words
The shielded connector according to claim 4, wherein said conductor has a third projection formed all around an outer surface of thereof to form a closed loop, said third projection being in close contact with said shielding element when said terminal assembly is assembled into said housing assembly.
Claim 7
Dependent Claim 15 words
The shielded connector according to claim 1, wherein said conductor is made of a metal.
Claim 8
Dependent Claim 52 words
The shielded connector according to claim 1, wherein said plug and said conductor are in a form of a conductive rubber, said conductive rubber being in contact with said second shield element of the shielding wire, and said conductive rubber being in contact with said first shield element of said housing assembly.
Claim 9
Dependent Claim 60 words
The shielded connector according to claim 1, wherein said housing assembly has a first stepped portion within the housing and said plug has a second stepped portion, said first stepped portion abuts said second stepped portion when said terminal assembly is fully inserted into said housing assembly, thereby preventing a further insertion of said terminal assembly into said housing assembly.
Claim 10
Dependent Claim 16 words
The shielded connector according to claim 1, wherein said housing is made of a synthetic resin.
Claim 11
Dependent Claim 66 words
The shielded connector according to claim 1 further including a mating connector into which said housing assembly having said terminal assembly assembled thereinto is inserted, said mating connector has a packing which seats between said housing assembly and said mating connector when said housing assembly is assembled into said mating connector, thereby said housing assembly and said mating connector being connected together in a watertight relation.
Claim 12
Dependent Claim 42 words
The shielded connector according to claim 1, wherein said housing assembly has a fourth projection on an outer surface thereof and said mating connector has a latching arm for engaging said fourth projection to lock said housing assembly with said mating connector.
