Abstract

Abstract A retaining device for securing the mating portions of a connector block in an assembled condition is disclosed. The retaining device includes a jackscrew having a first portion adapted to be secured in one connector block and a second portion adapted to be secured in the mating connector block. Both portions of the jackscrew include a shaft having an annular recess and adjacent annular shoulder on one end thereof. The recess and shoulder are adapted to be engaged by a plurality of radially deflectable locking tines mounted about a bore in each block, each tine having a locking detent on the free end thereof. The jackscrew may be removed from the associated block by a tool which, through a wedging action, spreads the locking tines radially outwardly to clear the respective annular shoulders. The jackscrew may be a single member or the two portions may be formed as separate members detachably secured together by means such as screw threads.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 118 words
In combination with a pair of mating connector blocks, each block carrying a plurality of pins or receptacles and having a bore, a coaxial counterbore, and a plurality of cantilever locking tines in said counterbore resiliently integral with said block and disposed about said bore, each said tine having a radially inwardly directed detent on the free end thereof, a jackscrew retaining means for securing said blocks in an assembled condition, said jackscrew retaining means comprising: first and second shafts each having an annular recess and an annular shoulder adjacent one end thereof, said recesses being engaged by said detents of said tines and gripping means on the other end of said first shaft for effecting rotation thereof.
Claim 2
Dependent Claim 118 words
In combination with a pair of mating connector blocks, each block carrying a plurality of pins or receptacles and having a bore, a coaxial counterbore, and a plurality of cantilever locking tines in said counterbore resiliently integral with said block and disposed about said bore, each said tine having a radially inwardly directed detent on the free end thereof, a jackscrew retaining means for securing said blocks in an assembled condition, said jackscrew retaining means comprising: first and second shafts each having an annular recess and an annular shoulder adjacent one end thereof, said recesses being engaged by said detents of said tines and gripping means on the other end of said first shaft for effecting rotation thereof.
Claim 3
Dependent Claim 36 words
The jackscrew retaining means according to claim 1 further comprising: a plurality of longitudinal slots formed in said shoulders at least equal in number and spacing to the spaces between tines of the associated connector block.
Claim 4
Dependent Claim 42 words
The jackscrew retaining means according to claim 1 further comprising: a threaded projection and a mating threaded recess on said one end of said first shaft and the other end of said second shaft, respectively, whereby said shafts are selectively joined together.
Claim 5
Dependent Claim 36 words
The jackscrew retaining means according to claim 3 further comprising: a head portion integral with the other end of said second shaft, said head portion being profiled to be nonrotatably received in the associated connector block.
Claim 6
Dependent Claim 16 words
The jackscrew retaining means according to claim 1 wherein said first and second shafts are integral.
Claim 7
Dependent Claim 62 words
The jackscrew retaining means according to claim 5 further comprising a plurality of cams equal in number and spacing to the spaces between tines of the associated block, said cams being integral with the shoulder of said second shaft and projecting into said annular recess whereby a rotary motion of said jackscrew will radially spread the tines of the associated connector block.
