US 3,940,838 A · Crimping tool for cable connector

Abstract

A crimping tool for use with a stranded cable connector having co-aligned sleeve openings, including a first member with a crimping portion; a piercing portion extended from the first crimping portion; a second member with a crimping portion and a recess for receiving the piercing portion and means to move the first and second crimping portions towards one another. A loose fitting cable connector sleeve with an inserted cable portion is positioned on the second crimping portion and the piercing portion is moved through the sleeve openings, thereby displacing the cable strands toward the interior wall of the sleeve, and forming a through passage. Movement of the cooperating crimping portions continues until the crimping portions have formed flat surface areas along the entire length of the sleeve thereupon and further movement is limited by an adjustable stop.

Dependent claims

Apparatus for forming a through connection passage in a stranded cable having a conductive sleeve mounted thereon in a loosely fit fashion, said sleeve being provided with first and second co-aligned openings, said apparatus comprising:

first means for forming a passage through said cable in the region between said co-aligned sleeve openings by displacement of the strands of said cable in a direction transverse to the axis of said sleeve and movement of said displaced strands towards the interior surface of said sleeve, the resulting passage being in alignment with said co-aligned sleeve openings;
and
crimping means for pressing at least the portions of said sleeve surrounding said sleeve openings towards one another to move said sleeve into intimate engagement with the adjacent strands of said cable,
whereby said cable and said sleeves are brought into intimate electrical engagement and the crimped regions surrounding said openings are formed to facilitate mechanical and electrical joining of a terminal thereto;
said first means operatively positioned within the formed passage to prevent collapse thereof during crimping of the sleeve and cable by said crimping means.

A crimping tool for forming a through passage in a stranded cable having thereon in a loosely fitted fashion a sleeve provided with first and second co-aligned openings, said crimping tool comprising:

a first member having a first crimping portion formed thereon;
a second member having a second crimping portion formed thereon;
a piercing portion extending from said first crimping portion toward said second crimping portion;
a recess communicating with said second crimping portion to receive said piercing portion;
and
means for moving said first and second crimping portions towards one another,
whereby said piercing portion forms a passage through said cable in the region between said co-aligned openings by displacement of the strands of said cable in a direction transverse to the axis of said sleeve and movement of said displaced strands toward the interior surface of said sleeve, the resulting passage being in alignment with said co-aligned sleeve opening and said piercing portion preventing collapse of the passage while first and second crimping portions press portions of said sleeve surrounding said sleeve openings into firm engagement with the adjacent strands of said cable to form a completed crimp.
