Abstract
Abstract A circular cross section DIN connector comprises, a wire housing (10), a contact housing (12) and a shielding shell (14). The wire housing (10) has a through bore (16) for receiving an end portion of a shielded electrical cable (C) with wires thereof dressed into notches (32) at one end (30) of the wire housing (10) and extending over slots (34) in the bases (33) of the notches (32). The housings (10 and 12) are mated so that insulation displacement portions (64) of contact elements (42) of the contact housing (12) enter the slots (34) to make electrical contact with the cores of the wires (W). The mated housings (10 and 12) are received in the shell (14) which completely surrounds them. Parts (90) of the shell (14) are crimped down to engage the shielding braid (BS) of the cable (C) and firmly to retain the sub-assembly comprising the mated housings (10 and 12) in the shell (14) which is preferably a seamless drawn shell.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
266 words
A circular cross section electrical connector assembly, comprising: a tubular, insulating, wire housing defining a central through bore and having a first end formed with a ring of wire receiving notches opening thereinto, each notch having a base and a slot opening thereinto, said housing having a second end opposite to said first end and by way of which a plurality of insulated wires of a shielded electrical cable can be inserted through the bore each for reception in a respective one of said notches; an insulating contact housing having a first end and a second end opposite thereto, a plurality of through cavities each opening into both of these ends, electrical contact elements secured in the cavities and each having a slotted, wire connection portion projecting from the first end of the contact housing and a mating portion at the other end thereof, the contact housing being matable with the wire housing to provide a sub-assembly in which each wire connecting portion is received in a respective slot of the wire housing to make permanent electrical connection with an insulated wire of said cable when said wire is received in a respective notch of the wire housing; and a open ended tubular metal shielding shell for receiving the whole of said sub-assembly therewithin with the second end of said wire housing proximate to a first end of said shell, said shell having means crimpable over the second end of the wire housing to engage shielding on said cable and means for restraining movement of said assembly towards a second and opposite end of said shell.
Claim 2
Dependent Claim
266 words
A circular cross section electrical connector assembly, comprising: a tubular, insulating, wire housing defining a central through bore and having a first end formed with a ring of wire receiving notches opening thereinto, each notch having a base and a slot opening thereinto, said housing having a second end opposite to said first end and by way of which a plurality of insulated wires of a shielded electrical cable can be inserted through the bore each for reception in a respective one of said notches; an insulating contact housing having a first end and a second end opposite thereto, a plurality of through cavities each opening into both of these ends, electrical contact elements secured in the cavities and each having a slotted, wire connection portion projecting from the first end of the contact housing and a mating portion at the other end thereof, the contact housing being matable with the wire housing to provide a sub-assembly in which each wire connecting portion is received in a respective slot of the wire housing to make permanent electrical connection with an insulated wire of said cable when said wire is received in a respective notch of the wire housing; and a open ended tubular metal shielding shell for receiving the whole of said sub-assembly therewithin with the second end of said wire housing proximate to a first end of said shell, said shell having means crimpable over the second end of the wire housing to engage shielding on said cable and means for restraining movement of said assembly towards a second and opposite end of said shell.
Claim 3
Dependent Claim
37 words
An assembly as claimed in claim 1, wherein said shielding shell defines an internal peripheral shoulder spaced from said second end thereof said sub-assembly defining a complimentary external peripheral shoulder for engaging against said internal peripheral shoulder.
Claim 4
Dependent Claim
39 words
An assembly as claimed in claim 1, wherein said crimpable means comprises a plurality of opposed lugs projecting from the first end of said shell, each lug defining an arcuate inner edge for embracing the shielding of said cable.
Claim 5
Dependent Claim
55 words
An assembly as claimed in claim 1, wherein said shell is a seamless, drawn, shielding shell having a portion projecting beyond the second end of the wire housing when said assembly is received in said shell, for crimping about the shielding of said cable so as to enclose the second end of the wire housing.
Claim 6
Dependent Claim
39 words
An assembly as claimed in claim 1, wherein said shell has internal keys bent inwardly therefrom said sub-assembly having external keyways for cooperation with said keys to ensure predetermined angular positioning of said shell with respect to said sub-assembly.
Claim 7
Dependent Claim
63 words
An assembly as claimed in claim 1, wherein the contact housing comprises a hood projecting from the first end thereof for receiving the wire housing, the hood defining an external shoulder facing the second end of the contact housing, said shell having a larger diameter portion for receiving said hood and a smaller diameter portion for receiving the remainder of the contact housing.
Claim 8
Dependent Claim
55 words
An assembly as claimed in claim 1, wherein the wire housing has a collar surrounding said second end thereof and defining an outwardly flared cable and wire guiding mouth of said through bore, for receiving an end portion of the shielding of said cable, said crimpable portion of said shell being crimpable over said collar.
