Abstract
Abstract A pre-molded insert for a high voltage cable accessory is formed near its entry with an interior annular recess or notch which permits the insert end to be deflected towards the central axis. The insert end in conjunction with a properly sized mandrel allows the same insert to be used with high voltage cables having a range of exterior diameters.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
An insert for use in the manufacture of a high voltage cable accessory having a body portion with a first bore therein, said first bore having a first end and a second end, said insert comprising: a) a first end and a second end, said first end of said insert positioned in said body portion adjacent said second end of said first bore; b) said insert having a second bore therethrough and communicating with said first bore of said body portion; c) an annular recess in said insert adjacent said second bore and adjacent said first end of said insert to define a weakened region; and d) the portion of said insert between said annular recess and said first end of said insert being deflectable towards the central longitudinal axis of said insert to control the diameter of the entry into said second bore, said deflectable portion of said insert being fixed in position by the formation of said body portion about said insert.
Claim 2
Dependent Claim
164 words
An insert for use in the manufacture of a high voltage cable accessory having a body portion with a first bore therein, said first bore having a first end and a second end, said insert comprising: a) a first end and a second end, said first end of said insert positioned in said body portion adjacent said second end of said first bore; b) said insert having a second bore therethrough and communicating with said first bore of said body portion; c) an annular recess in said insert adjacent said second bore and adjacent said first end of said insert to define a weakened region; and d) the portion of said insert between said annular recess and said first end of said insert being deflectable towards the central longitudinal axis of said insert to control the diameter of the entry into said second bore, said deflectable portion of said insert being fixed in position by the formation of said body portion about said insert.
Claim 3
Dependent Claim
16 words
An insert as defined in claim 1, wherein said first end of said insert is rounded.
Claim 4
Dependent Claim
22 words
An insert as defined in claim 1, wherein said portion of said insert between said recess and said first end deflects symmetrically.
Claim 5
Independent Claim
213 words
A method of manufacturing a cable accessory having a premolded outer part, a body portion having a first bore therein, said first bore having a first end and a second end and an insert having a first end and a second end and a second bore therethrough, said first end of said insert being adjacent said second end of said first bore and said second bore communicating with said first bore, a portion of said insert adjacent said first end of said insert being deflectable towards the central longitudinal axis of said insert to decrease the diameter of the entrance into said second bore comprising the steps of: a) placing said premolded outer part in a mold cavity; b) deflecting said portion of said insert inwardly towards said central longitudinal axis by a first amount; c) placing said insert in said mold cavity and within a portion of said premolded outer part; d) inserting a mandrel of a first predetermined diameter into said mold cavity within at least a portion of said premolded outer part and adjacent said insert first end; and e) filling the interstices between said premolded outer part, said insert and said mandrel with moldable material to complete said accessory whereby said first bore is of said first predetermined diameter.
Claim 6
Independent Claim
213 words
A method of manufacturing a cable accessory having a premolded outer part, a body portion having a first bore therein, said first bore having a first end and a second end and an insert having a first end and a second end and a second bore therethrough, said first end of said insert being adjacent said second end of said first bore and said second bore communicating with said first bore, a portion of said insert adjacent said first end of said insert being deflectable towards the central longitudinal axis of said insert to decrease the diameter of the entrance into said second bore comprising the steps of: a) placing said premolded outer part in a mold cavity; b) deflecting said portion of said insert inwardly towards said central longitudinal axis by a first amount; c) placing said insert in said mold cavity and within a portion of said premolded outer part; d) inserting a mandrel of a first predetermined diameter into said mold cavity within at least a portion of said premolded outer part and adjacent said insert first end; and e) filling the interstices between said premolded outer part, said insert and said mandrel with moldable material to complete said accessory whereby said first bore is of said first predetermined diameter.
Claim 7
Dependent Claim
84 words
The method of manufacturing a cable accessory as defined in claim 4, comprising the additional steps of: a) deflecting said portion of said insert inwardly towards said central longitudinal axis a greater amount than said first amount; b) inserting a mandrel of a second predetermined diameter into said mold cavity within a least a portion of said premolded outer part and adjacent said insert first end; and c) filling the interstices with moldable material whereby said first bore is of said second predetermined diameter.
