Tool-less and visual feedback cable connector interface
An electrical connector interface has a male portion and a female portion. The male portion provided with at least three outer diameter radial projecting connector tabs and a conical outer diameter seat surface at an interface end. A releasable retainer seats upon the male portion. The female portion provided with at least three outer diameter radial projecting base tabs and an annular groove open to the interface end with an outer sidewall dimensioned to mate with the conical outer diameter seat surface. the releasable retainer dimensioned to engage the base tabs, upon rotation of the releasable retainer, retaining the outer diameter seat surface against the outer sidewall. A handle projection of the releasable retainer and/or visual engagement indicia may be applied for ease of tool-less interconnection and/or verification of engagement.
1. A cable connector interface, comprising:
a male portion with at least three outer diameter radially projecting connector tabs; the male portion provided with a conical outer diameter seat surface at an interface end;
a releasable retainer dimensioned to seat around the male portion,
a female portion with at least three outer diameter radial projecting base tabs and an annular groove open to the interface end with an outer sidewall dimensioned to mate with the conical outer diameter seat surface;
the connector tabs mesh with the base tabs as the conical outer diameter seat surface is seated against the outer sidewall, inhibiting rotation of the male portion with respect to the female portion;
the releasable retainer dimensioned to engage the base tabs, upon rotation of the releasable retainer, retaining the conical outer diameter seat surface against the outer sidewall.
2. The connector interface of claim 1 , further including a handle projection extending radially from an outer diameter of the releasable retainer.
3. The connector interface of claim 2 , wherein the handle projection has an enlarged distal end.
4. The connector interface of claim 2 , further including visual feedback indicia on the female portion.
5. The connector interface of claim 4 , wherein the visual feedback indicia is an engagement verification indicia, which is uncovered by the handle projection when the releasable retainer is in an engaged position and covered when the handle projection is in a dis-engaged position.
6. The connector interface of claim 1 , further including an indicator on the releasable retainer, the indicator proximate an engagement verification indicia on the female portion when the releasable retainer is in an engaged position and proximate a disengagement verification indicia when the releasable retainer is in a dis-engaged position.
7. The connector interface of claim 6 , wherein the indicator is a protrusion provided on an outer diameter of the releasable retainer.
8. The connector interface of claim 6 , wherein the indicator is an indentation provided on an outer diameter of the releasable retainer.
9. The connector interface of claim 1 , wherein a cable end of the base tab is provided with an angled engagement surface; the engagement surface progressively drawing the coupling tab and thereby the male portion towards the female portion as the releasable retainer is rotated.
10. The connector interface of claim 1 , wherein the releasable retainer is provided with a stop shoulder with a radially inward projecting retention lip; the retention lip engaging a radial outward protruding retention spur of the male portion, retaining the releasable retainer upon the male portion.
11. The connector interface of claim 10 , wherein the retention spur is provided on an overbody covering an outer diameter of the male portion between a cable end and the connector tabs.
12. The connector interface of claim 1 , further including an annular groove provided in the outer diameter seat surface, in which a seal is seated.
13. A method for interconnecting an electrical connector, comprising:
providing a male portion with at least three outer diameter radially projecting connector tabs; the male portion provided with a conical outer diameter seat surface at an interface end;
seating a releasable retainer around the male portion;
inserting the interface end of the male portion into an interface end of a female portion with at least three outer diameter radially projecting base tabs, and an annular groove open to the interface end with an outer sidewall dimensioned to mate with the conical outer diameter seat surface; and
the connector tabs mesh with the base tabs as the conical outer diameter seat surface is seated against the outer sidewall, inhibiting rotation of the male portion with respect to the female portion; and
rotating the releasable retainer to engage the base tabs, thereby retaining the conical outer diameter seat surface against the outer sidewall.
14. The method of claim 13 , wherein the rotation of the releaseable retainer is sixty degrees or less.
15. The method of claim 13 , wherein the releasable retainer is rotated via grasping a handle projection extending from an outer diameter of the releaseable retainer.
16. The method of claim 13 , wherein the connector tab is provided with an outer diameter stop surface dimensioned to provide a positive stop with respect to rotation of the tab seat lock past the base tab lock.
17. The method of claim 13 , wherein a cable end of the base tab is provided with an angled engagement surface; the engagement surface progressively drawing a coupling tab of the releasable retainer and thereby the male portion towards the female portion as the releasable retainer is rotated.
18. The method of claim 13 , further including rotating the releasable retainer until an engagement verification indicia of the female portion is exposed by the releasable retainer.
