Plugless normally-open connector module
View Patent ↗A connector module, which permits termination of cross-connect wires on one surface and cable wires on an opposite surface, has an internal switch configuration which is normally open, such that the cross-connect wires are normally not connected to the cable wires. The module exhibits a generally “Z” shaped configuration which permits test access, jumper insertion, and protector mounting on either surface.
1. A connector module comprising:
a housing having a first surface and a different, second surface;
first and second rows of contacts mounted within said housing, each contact including an end portion which is capable of providing electrical connection to a corresponding wire and a stem portion, said contacts being mounted so that said end portions of said first row of contacts are located adjacent said first surface and said end portions of said second row of contacts are located adjacent said second surface, and said contacts being mounted so that each stem portion of said first row of contacts faces a corresponding stem portion of said second row of contacts without making electrical contact with the corresponding stem portion of said second row of contacts;
a first row of slots formed in said housing, each slot for receiving therein a lead which can electrically connect the stem portion of one of said first row of contacts to the corresponding stem portion of said second row of contacts; and
a second row of slots formed in said housing, each slot for receiving therein a lead which can electrically connect the stem portion of one of said first row of contacts to the corresponding stem portion of said second row of contacts.
2. The connector module according to claim 1 , further comprising:
a spacer provided in said housing between corresponding stem portions of said first and second rows of contacts, wherein said spacer is formed of an electrically insulating material and ensures that facing stem portions of said first and second rows of contacts do not make electrical contact with each other.
3. The connector module according to claim 2 , wherein said spacer is an integrally molded piece of said housing.
4. The connector module according to claim 1 , wherein each end portion of each contact includes an insulation piercing slot.
5. The connector module according to claim 1 , wherein said second surface of said housing is opposite to said first surface of said housing.
6. The connector module according to claim 5 , wherein said first row of slots are formed in said first surface of said housing and said second row of slots are formed in said second surface of said housing.
7. The connector module according to claim 5 , wherein said end portions of said first row of contacts are laterally displaced on said first surface of said housing as compared to a placement of said second row of contacts on said second surface of said housing.
8. A connector module according to claim 1 , further comprising:
a protector component with at least one lead inserted into a slot of said first and second rows of slots.
9. A connector module according to claim 1 , wherein said housing includes:
a first insulating cap placed over said first surface of said housing, said first insulating cap including a first row of slits aligned with said end portions of said first row of contacts to permit wires to be inserted therein for making electrical connection with said end portions of said first row of contacts; and
a second insulating cap placed over said second surface of said housing, said second insulating cap including a second row of slits aligned with said end portions of said second row of contacts to permit wires to be inserted therein for making electrical connection with said end portions of said second row of contacts.
10. A connector module according to claim 9 , wherein said first row of slots are formed in said first insulating cap, and said second row of slots are formed in said second insulating cap.
11. A connector module according to claim 1 , wherein each stem portion of said first and second rows of contacts has two potential electrical contact points, including a first electrical contact point being aligned with a slot of said first row of slots and a second electrical contact point being aligned with a slot of said second row of slots.
12. A connector module according to claim 11 , wherein said electrical contact points include raised surfaces of said stem portions.
13. A connector according to claim 12 , wherein said raised surfaces are coated with a conductive material.
14. A connector module according to claim 1 , wherein at least one stem portion of facing corresponding stem portions of the said first and second rows of contacts includes a non-conductive portion which physically engages the other corresponding stem portion to ensure a spacing between conductive portions of the facing corresponding stem portions.
15. A connector module according to claim 14 , wherein said non-conductive portion includes a non-conductive material applied to a raised portion of said at least one stem portion.
16. A connector module according to claim 1 , wherein each stem portion of said first and second rows of contacts has a non-conductive portion, wherein said non-conductive portion includes a non-conductive material, which physically touches another non-conductive portion of a facing, corresponding stem portion.
17. A connector module comprising:
an insulating housing having a top surface and a bottom surface;
first and second rows of contacts mounted within said housing, each contact including an end portion which is capable of providing electrical connection to a corresponding wire and a stem portion, said contacts being mounted so that said end portions of said first row of contacts are located adjacent said top surface and said end portions of said second row of contacts are located adjacent said bottom surface, the end portions of the said first and second rows of contacts being laterally displaced, and said contacts being mounted so that each stem portion of said first row of contacts faces a corresponding stem portion of said second row of contacts without making electrical contact with the corresponding stem portion of said second row of contacts;
a first row of slots formed in said top surface adjacent to said end portions of said first row of contacts, each slot for receiving therein a lead which can electrically connect the stem portion of one of said first row of contacts to the corresponding stem portion of said second row of contacts; and
a second row of slots formed in said bottom surface adjacent to said end portions of said second row of contacts, each slot for receiving therein a lead which can electrically connect the stem portion of one of said first row of contacts to the corresponding stem portion of said second row of contacts.
18. The connector module according to claim 17 , further comprising:
a spacer provided in said housing between corresponding stem portions of said first and second rows of contacts, wherein said spacer is formed of an electrically insulating material and insures that facing stem portions of said first and second rows of contacts do not make electrical contact with each other.
19. The connector module according to claim 18 , wherein said spacer is an integrally molded piece of said housing.
