US4244638A — Snap-in strain relief

Claim 1

Independent Claim 171 words

In combination with an electrical connector housing having at least two parallel spaced terminal carrying portions defining at least one elongated slot between each adjacent pair of rows and a plurality of parallel spaced bars subdividing said slot into a plurality of passages, a strain relief member detachably secured to said connector, said strain relief member comprising: a plate of rigid material having an overall rectangular plan profile, with an integral pair of legs extending from one side thereof and set in from corners thereof to form outwardly directed first shoulders adjacent the legs, each leg having a profiled free end including an outwardly and rearwardly directed slope forming a second outwardly and rearwardly directed shoulder spaced from the first shoulder and adapted to engage opposite ends of a respective bar in said slot; and a patterned array of apertures in said plate whereby said plate is attached to said connector housing and conductors are secured in said plate by tie down means passing through said apertures and around said conductors.

Claim 2

Dependent Claim 171 words

In combination with an electrical connector housing having at least two parallel spaced terminal carrying portions defining at least one elongated slot between each adjacent pair of rows and a plurality of parallel spaced bars subdividing said slot into a plurality of passages, a strain relief member detachably secured to said connector, said strain relief member comprising: a plate of rigid material having an overall rectangular plan profile, with an integral pair of legs extending from one side thereof and set in from corners thereof to form outwardly directed first shoulders adjacent the legs, each leg having a profiled free end including an outwardly and rearwardly directed slope forming a second outwardly and rearwardly directed shoulder spaced from the first shoulder and adapted to engage opposite ends of a respective bar in said slot; and a patterned array of apertures in said plate whereby said plate is attached to said connector housing and conductors are secured in said plate by tie down means passing through said apertures and around said conductors.

Claim 3

Dependent Claim 27 words

The strain relief member according to claim 1 wherein said legs are spaced apart a distance not greater than the spacing between adjacent bars of said housing.

Claim 4

Dependent Claim 45 words

The strain relief member according to claim 1 wherein said legs are spaced apart a distance substantially equal to the spacing between two bars of said housing and further comprising a notch in said one side adapted to receive therein bars spanned by said legs.

Claim 5

Dependent Claim 30 words

The strain relief member according to claim 1 further comprising a profiled extension on at least one surface of said member, said extension adapted to gather together conductors placed therein.

Claim 6

Dependent Claim 147 words

A strain relief member for selective and removable attachment to an electrical connector housing having at least one elongated slot therein, said strain relief member comprising: a rigid plate of insulating material having a generally rectangular configuration with a patterned array of apertures therein; bundle tie means passing through a spaced pair of said apertures and encircling a portion of said member and conductors positioned thereagainst; and a pair of integral legs extending from one side edge of said plate, each leg being stepped inwardly from a corner of said edge to define a first shoulder, the free end of each leg having an outwardly sloped surface defining an outwardly and rearwardly directed second shoulder spaced from said first shoulder, whereby said member is detachably secured in said connector by said legs with said shoulders engaging opposite sides of said housing at opposite ends of said slot.

Claim 7

Dependent Claim 147 words

A strain relief member for selective and removable attachment to an electrical connector housing having at least one elongated slot therein, said strain relief member comprising: a rigid plate of insulating material having a generally rectangular configuration with a patterned array of apertures therein; bundle tie means passing through a spaced pair of said apertures and encircling a portion of said member and conductors positioned thereagainst; and a pair of integral legs extending from one side edge of said plate, each leg being stepped inwardly from a corner of said edge to define a first shoulder, the free end of each leg having an outwardly sloped surface defining an outwardly and rearwardly directed second shoulder spaced from said first shoulder, whereby said member is detachably secured in said connector by said legs with said shoulders engaging opposite sides of said housing at opposite ends of said slot.

Claim 8

Dependent Claim 151 words

In combination with an electrical connector housing having two parallel spaced terminal carrying portions defining at least one elongated slot therebetween a plurality of integral bars in parallel spaced relation dividing said slot into a plurality of equal passageways, a strain relief member detachably secured to said connector, said strain relief member comprising: a plate of rigid material having an overall rectangular plan profile with an integral pair of legs extending from one side thereof, each leg being stepped inwardly from an adjacent corner to define a first shoulder and having a sloped free end defining an outwardly and rearwardly directed second shoulder, said legs being received in a passageway with said shoulders engaging opposite ends of a respective bar; a patterned array of apertures in said plate; and bundle tie means passing through said apertures and around conductors and portions of said strain relief member to secure said conductors thereto.

Claim 9

Dependent Claim 151 words

In combination with an electrical connector housing having two parallel spaced terminal carrying portions defining at least one elongated slot therebetween a plurality of integral bars in parallel spaced relation dividing said slot into a plurality of equal passageways, a strain relief member detachably secured to said connector, said strain relief member comprising: a plate of rigid material having an overall rectangular plan profile with an integral pair of legs extending from one side thereof, each leg being stepped inwardly from an adjacent corner to define a first shoulder and having a sloped free end defining an outwardly and rearwardly directed second shoulder, said legs being received in a passageway with said shoulders engaging opposite ends of a respective bar; a patterned array of apertures in said plate; and bundle tie means passing through said apertures and around conductors and portions of said strain relief member to secure said conductors thereto.
