US5399096A — Electrical connector having a threaded ring and m…

Claim 1

Independent Claim 175 words

Electrical connector having: body means for receiving electrical contacts; a threaded rotary locking nut for cooperation with a threaded portion of a matching connector, said locking nut being retained against forward axial movement beyond a predetermined position on said body means; a ratchet washer axially slidable on and non-rotatably connected to said nut and formed with axially directed ratchet teeth having edges each separating a cam face with a lower slope from a ratchet face with a steeper slope relative to a circumferential direction; a separate one-piece ring of synthetic material having a radially inner portion for secured connection with said body means and an outer portion formed with additional teeth for engaging said ratchet teeth to establish a ratchet effect that opposes rotation of the ring in an unscrewing direction in which the additional teeth come into abutment against the steeper sloping ratchet faces; and a spring wavy metal washer interposed between said ratchet washer and said nut for exerting an axially directed force on said ratchet washer applying the latter against said ring.

Claim 2

Dependent Claim 175 words

Electrical connector having: body means for receiving electrical contacts; a threaded rotary locking nut for cooperation with a threaded portion of a matching connector, said locking nut being retained against forward axial movement beyond a predetermined position on said body means; a ratchet washer axially slidable on and non-rotatably connected to said nut and formed with axially directed ratchet teeth having edges each separating a cam face with a lower slope from a ratchet face with a steeper slope relative to a circumferential direction; a separate one-piece ring of synthetic material having a radially inner portion for secured connection with said body means and an outer portion formed with additional teeth for engaging said ratchet teeth to establish a ratchet effect that opposes rotation of the ring in an unscrewing direction in which the additional teeth come into abutment against the steeper sloping ratchet faces; and a spring wavy metal washer interposed between said ratchet washer and said nut for exerting an axially directed force on said ratchet washer applying the latter against said ring.

Claim 3

Dependent Claim 81 words

Connector according to claim 1, wherein: said radially inner portion of said one-piece ring is formed with a plurality of angularly distributed resilient locking fingers integral therewith and with axial slots; and said body means are formed with circumferential groove means for receiving said resilient locking fingers and preventing axially rearward movement of said ring with respect to said body means and with radial projections engaging into said axial slots for preventing rotation of said ring relative to said body means.

Claim 4

Dependent Claim 14 words

Electrical connector according to claim 1, wherein said ratchet washer is of synthetic material.

Claim 5

Dependent Claim 120 words

Electrical connector having: body means for receiving contacts; a threaded rotary locking nut for cooperation with a threaded portion of a matching connector, said locking nut being rotatably supported by said body means, being retained against forward movement with respect to said body means by abutment means and being formed with radially inwardly directed circumferentially distributed ratchet teeth having edges each separating a cam face with a lower slope from a ratchet face with a steeper slope relative to a circumferential direction; a separate one-piece ring of synthetic material securely and non-rotatably connected to said body means and having cantilever resilient fingers integrally formed therewith and each having an end radially engaging said ratchet teeth due to the resiliency thereof.

Claim 6

Dependent Claim 120 words

Electrical connector having: body means for receiving contacts; a threaded rotary locking nut for cooperation with a threaded portion of a matching connector, said locking nut being rotatably supported by said body means, being retained against forward movement with respect to said body means by abutment means and being formed with radially inwardly directed circumferentially distributed ratchet teeth having edges each separating a cam face with a lower slope from a ratchet face with a steeper slope relative to a circumferential direction; a separate one-piece ring of synthetic material securely and non-rotatably connected to said body means and having cantilever resilient fingers integrally formed therewith and each having an end radially engaging said ratchet teeth due to the resiliency thereof.

Claim 7

Dependent Claim 39 words

Electrical connector according to claim 4, wherein said one-piece ring is slidably keyed on said body means and is retained against a shoulder of said body means by a split ring seated in a groove of said body means.
