Abstract
Abstract A controlled impedance connector assembly includes a receptacle adapted for mounting on a printed circuit board (PCB) and for mating reception of a plug which carries terminal contacts of a plurality of coaxial cable leads. A honeycomb grounding block is mounted in the plug to engageably receive the outer conductor of each coaxial terminal, the inner conductive sleeve of each coaxial terminal being electrically coupled to a signal lead by a first contact member. Signal pin contacts within the receptacle and electrically coupled with the PCB are electrically coupled with each inner conductive sleeve when the plug is inserted into the receptacle. Likewise, ground pin contacts within the receptacle and electrically coupled with the PCB have second and third spaced resilient contact members, respectively, engaging the grounding block at distances farther from and nearer to the PCB than the first contact members. Within each coaxial terminal, air is a primary dielectric between the outer diameter of the signal lead and the inner diameter of the ground lead and the distance between the two is controlled to thereby maintain a substantially uniform impendance in the region of the connector matched to that of the coaxial lead. The signal and ground pin contacts may be pre-assembled in a holding block for shipping enabling ready assembly into the receptacle and, thereafter, connection to the PCB at the time the connector assembly is being installed. The plug is of a sturdy clam shell design, and reusable zipper-type tubing is used as a jacket to protectively enclose the coaxial cable leads in a bundle as they extend away from the plug.

A plug assembly as set forth in Claim 44 wherein said outer protective covering is composed of plastic sheet material and includes a closure mechanism operable for selectively opening said sheet material to expose said bundle of leads and for closing said sheet material into fitting and encompassing relationship about said bundle of leads to thereby hold them as a unit.
Claim 49
Dependent Claim

A plug assembly as set forth in Claim 46 wherein said outer protective covering is composed of plastic sheet material and includes a closure mechanism operable for selectively opening said sheet material to expose said bundle of leads and for closing said sheet material into fitting and encompassing relationship about said bundle of leads to thereby hold them as a unit.
Claim 51
Dependent Claim
286 words
In the production of a controlled impedance connector assembly, a combination of components comprising: a receptacle of dielectric material adapted to be mounted on a printed circuit board having a plurality of metallized through holes therein, said receptacle also adapted for mating engagement with a plug and including a planar base member adapted for positioning generally parallel to and proximately spaced from a planar surface of the printed circuit board, said base member having an upper surface and a lower surface and a plurality of mounting recesses extending transversely through a part of said base member and open to said upper surface and smaller reception holes therein associated with each recess extending to said lower surface to enable communication between said upper surface and said lower surface; a plurality of elongated pin contacts, each extending between a nose end and a tail end, said nose end having at least one resilient contact member engageable with an associated socket of the plug; said tail end of each of said pin contacts being engageable with an associated through hole in the printed circuit board and electrically connected thereto, each said pin contact including an enlarged barrel member intermediate said nose end and said tail end; a holding block having a planar engagement surface and a plurality of transverse bores formed therein, each bore adapted to engageably receive said resilient contact member of an associated one of said pin contacts; and stay means releasably supporting said holding block such that said engagement surface is generally parallel to and spaced from said upper surface and such that said tail end of each of said pin contacts is received in an associated one of the reception holes in said base member.

Claim 53
Dependent Claim
145 words
A combination of components as set forth in Claim 48 wherein, when said holding block is selectively moved against the force of said stay means toward said base member such that said engagement surface engages said upper surface of said base member, said enlarged barrel member of each of said pin contacts is engageably received in an associated funnel shaped mounting recess in said base member and said tail ends of all of said pin contacts extend through and beyond the metallized through holes of the printed circuit board; and including: solder applied to said tail ends and to the metallized through holes to thereby mechanically and electrically couple said tail ends to the printed circuit board; whereby said holding block can thereupon be withdrawn from said base member so as to be disengaged from said pin contacts and removed from said combination of components.
Claim 54
Dependent Claim
162 words
A combination of components as set forth in Claim 49 wherein said pin contacts include a plurality of signal pin contacts having a first said resilient contact member, each said first resilient contact member being engageable with an associated socket in the plug coupled to a signal lead at a first predetermined distance away from the circuit board; and wherein said pin contacts include a plurality of ground pin contacts having second and third longitudinally spaced resilient contact members, each pair of said resilient contact members being engageable with an associated socket in the plug electrically coupled to ground potential, each of said second contact members being engaged with its associated socket at a second predetermined distance away from the printed circuit board which is greater than the first predetermined distance, each of said third contact members being engaged with its associated socket at a third predetermined distance away from the printed circuit board which is less than the first predetermined distance.
