TOOL-LESS INSULATION DISPLACEMENT CONNECTOR (TIDC) LOCKING MARKER CAP
A locking marker cap has structural features to snap lock to various types of a tool-less insulation displacement connector (TIDC). When the cap is attached to the TIDC, additional structural features of the cap lock a latch of the TIDC in a closed position to protect the TIDC from being accidentally opened and coincidentally disconnecting the circuit served by the TIDC. In one embodiment, the cap must be removed before the TIDC can be unlatched and opened. At least a top surface of the cap can include indicia such as a color, letter(s) or symbol(s) to indicate a type of circuit served by the protected TIDC.
1 . A cap for attachment to a tool-less insulation displacement connector (TIDC) to block a pivoting movement of a latch of the TIDC while attached to the TIDC comprising:
a top;
at least one blocking tab attached to said top; and
at least one locking tab attached to said top, wherein when said at least one locking tab is engaged to a portion of the TIDC, said blocking tab blocks a pivoting movement path of the latch such that opening of the latch is prohibited.
2 . The cap of claim 1 , wherein said at least one locking tab includes a hook to engage a portion of the TIDC.
3 . The cap of claim 1 , wherein said at least one locking tab is a first resilient locking tab, and further comprising:
a second resilient locking tab attached to said top, wherein said first and second resilient locking tabs are located proximate opposing edges of said top.
4 . The cap of claim 3 , wherein said first resilient locking tab includes a first hook, said second resilient locking tab includes a second hook, and said first and second hooks face each other in order to capture a portion of the TIDC therebetween.
5 . The cap of claim 1 , wherein said at least one blocking tab is a first blocking tab and further comprising:
a second blocking tab attached to said top.
6 . The cap of claim 5 , wherein said first and second blocking tabs are located proximate opposing edges of said top.
7 . The cap of claim 6 , wherein said cap may be attached to said TIDC In two different orientations, in a first orientation said first blocking tab blocks the pivoting movement path of the latch such that opening of the latch is prohibited, and in a second orientation said second blocking tab blocks the pivoting movement path of the latch such that opening of the latch is prohibited.
8 . The cap of claim 1 , wherein said top is formed as a generally planar member.
9 . The cap of claim 1 , further comprising:
indicia formed on or in said top for indicating a nature of a circuit passing though the TIDC to which said cap is to be attached.
10 . The cap of claim 9 , wherein said indicia is in the form of letters or symbols formed on or in a material constituting said top.
11 . The cap of claim 9 , wherein said indicia is in the form of a color of a material used to form said top.
12 . The cap of claim 1 , wherein said cap is formed of plastic.
13 . A tool-less insulation displacement connector (TIDC) comprising:
a top section and a bottom section, said top section being movable between an open position and a closed position relative to said bottom section;
a latch attached to said top section and having an engaging portion adapted to engage a corresponding retention member on said bottom section to hold said top section in said closed position, wherein said latch can be opened by pivoting said latch such that said engaging portion releases from said retention member so that said top section can be moved to said open position;
wherein the improvement comprises,
a cap attached to said TIDC to prevent opening of said latch of said TIDC including:
a top;
at least one blocking tab attached to said top; and
at least one locking tab attached to said top, wherein when said at least one locking tab is engaged to a portion of said TIDC, said blocking tab blocks a pivoting movement path of said latch such that opening of said latch is prohibited.
14 . The TIDC of claim 13 , wherein said cap is removably attached to said TIDC and can be removed by disengaging said at least one locking tab from said portion of said TIDC.
15 . The TIDC of claim 13 , wherein said latch is attached to said top section by a hinge and further comprising:
a recess formed in said top section adjacent to said hinge, wherein a portion of said latch must pivot into said recess when said engaging portion of said latch Is released from said retention member of said bottom section, such that said recess resides In the pivoting movement path of said latch, and wherein said at least one blocking tab occupies said recess when said at least one locking tab is engaged to said portion of said TIDC.
16 . The TIDC of claim 13 , wherein said at least one locking tab includes a hook, said top section includes a slot extending into said TIDC past a ledge, and said at least one locking tab extends into said slot, and wherein said hook engages said ledge to attached said cap to said TIDC.
17 . The TIDC of claim 13 , wherein said at least one locking tab is a first resilient locking tab, and further comprising:
a second resilient locking tab attached to said top, wherein said first and second resilient locking tabs are located proximate opposing edges of said top, said first resilient locking tab includes a first hook, said second resilient locking tab includes a second hook, and said first and second hooks face each other in order to capture a portion, of the TIDC therebetween.
18 . The TIDC of claim 17 , wherein said top section includes a first slot extending into said TIDC past a first ledge and a second slot extending into said TIDC past a second ledge, and said first and second resilient locking tabs extend into said first and second slots respectively, and said first hook engages said first ledge and said second hook engages said second ledge to attached said cap to said TIDC.
19 . A method of locking and unlocking a latch on a tool-less insulation displacement connector (TIDC) comprising:
providing a TIDC with a top section and a bottom section, the top section being movable between an open position and a closed position relative to the bottom section; a latch attached to the top section and having an engaging portion adapted to engage a corresponding retention member on the bottom section to hold the top section in the closed position, wherein the latch can be opened by pivoting the latch such that the engaging portion releases from the retention member so that the top section can be moved to the open position;
providing a cap including a top; at least one blocking tab attached to the top; and at least one locking tab attached to the top;
attaching the cap to the TIDC by engaging the at least one locking tab to a portion of the TIDC; and
blocking a pivoting movement path of the latch such that opening of the latch is prohibited by inserting the at least one blocking tab into the pivoting movement path of the latch.
20 . The method of claim 19 , further comprising:
removing the cap from the TIDC by disengaging the at least one locking tab from the portion of the TIDC; and
permitting pivoting movement of the latch such that opening of the latch is allowed by removing the at least one blocking tab from the pivoting movement path of the latch.
