Cartridge lock registered jack and method of use thereof
View Patent ↗The present invention relates to a cartridge lock registered jack and method of use thereof. The cartridge allows wires to be fed through and pulled tight around a retaining bar. This ensures that the wires terminate with the insulation displacement contact very close to the point at which the wires are still twisted. Termination is made by moving the cartridge to a locked position, which then pushes the wires into the insulation displacement contacts that displace the wire insulation to make contact.
1. A cartridge lock registered jack comprising:
a housing, having a plug socket opening and a cartridge cavity;
at least one conductive terminal, located within the housing, the conductive terminal having a first contact portion and a second contact portion, wherein the second contact portion extends into the socket; and
a cartridge member, having two opposing box-wing portions flexibly attached to a gate portion including at least one vertical opening through which the first contact portion is extendable, wherein the cartridge member includes a retaining bar spaced apart from the at least one vertical opening and around which an insulated wire is positionable,
wherein the cartridge member moves with respect to the housing between a first unlocked position and a second locked position, wherein when the cartridge member is in the second locked position the retaining bar acts upon an insulated wire positioned partially around the retaining bar and terminates the wire into electrical connection with the first contact portion of a corresponding at least one conductive terminal.
2. The cartridge lock registered jack connector jack of claim 1 , wherein the cartridge further comprises a locking tab operable with a pocket of the cartridge cavity.
3. The cartridge lock registered jack connector jack of claim 1 , wherein the cartridge member further comprises a guide rail operable with a guide track of the cartridge cavity.
4. The cartridge lock registered jack connector jack of claim 3 , wherein the cartridge member is movable between the first unlocked position and the second locked position in a direction substantially parallel to the direction of extension of the socket into the housing.
5. The cartridge lock registered jack connector jack of claim 3 , wherein the cartridge member further comprises at least one gripping rib positioned on an inner surface of a box-wing portion.
6. The cartridge lock registered jack connector jack of claim 1 , wherein the first contact portion has a sharpness sufficient to pierce the insulation of the at least one insulated wire.
7. The cartridge lock registered jack connector jack of claim 1 , wherein the housing is assembled from at least two pieces.
8. The cartridge lock registered jack connector jack of claim 1 , wherein the at least one insulated wire is perpendicularly aligned with the first contact portion, wherein the insulation of the wire is pierced by the first contact portion when the retaining bar of the cartridge is moved to a locked position.
9. The cartridge lock registered jack connector jack of claim 1 , wherein the jack is an RJ-45 jack.
10. A cartridge lock registered jack comprising:
a housing portion;
a plug socket, extending into the housing portion;
a cartridge cavity, extending into the housing portion;
a plurality of insulation displacement contacts located within the housing portion; and
a cartridge sized for insertion into the cartridge cavity in a direction substantially parallel to the direction of extension of the socket into the housing portion, the cartridge including a plurality of openings corresponding in size to the plurality of insulation displacement contacts, so that the plurality of insulation displacement contacts are each extendable through the plurality of openings when the cartridge resides in a locked position; and wherein the cartridge includes a retaining bar having a plurality of grooves for receiving a plurality of insulated wires wrapped around the retaining bar prior to and during insertion of the cartridge into the cartridge cavity, so that the plurality of insulated wires are electrically contacted by the plurality of insulation displacement contacts extending through the plurality of openings.
11. The cartridge lock registered jack of claim 10 , wherein the cartridge includes locking tabs positioned to employ an interference fit with corresponding structure of the cavity.
12. The cartridge lock registered jack of claim 11 , wherein the cartridge cavity includes guide tracks.
13. The cartridge lock registered jack of claim 10 , wherein cartridge includes guide rails.
14. The cartridge lock registered jack of claim 10 , wherein the cartridge includes opposing box-wing portions.
15. The cartridge lock registered jack of claim 14 , wherein the opposing box-wing portions each include inner gripping ribs.
16. A method for assembling a cartridge lock registered jack, the method comprising:
providing a housing, having a plug socket and a cartridge cavity;
providing at least one conductive terminal within the housing, the conductive terminal having a first contact portion and a second contact portion;
providing a cartridge member having a retaining bar spaced apart from a gate portion having a plurality of openings, the cartridge member being movable with respect to the housing;
feeding at least one insulated wire through a space between the openings of the gate portion and the retaining bar;
pulling tight at least one insulated wire and bending it about the retaining bar; and
moving the cartridge member into the cartridge cavity until the tightened at least one insulated wire bent around the retaining bar is terminated and held in electrical contact with the first contact portion of a corresponding at least one conductive terminal.
17. The method of claim 16 , wherein the housing is assembled from at least two pieces.
18. The method of claim 16 , wherein the cartridge includes locking tabs and the cartridge cavity includes corresponding pockets into which the locking tabs extend when the cartridge obtains a locked position.
19. The method of claim 16 , further comprising crimping the wire cable between two opposing box-wing portions of the cartridge.
20. The method of claim 16 , wherein movement of the cartridge into the cartridge cavity is enhanced by operable interaction of guide rails of the cartridge with guide tracks of the cavity.
21. A cartridge lock registered jack comprising:
a housing, having a plug socket;
at least one conductive terminal within the housing, the conductive terminal having a first contact portion and a second contact portion;
a cavity extending into the housing, the cavity including pockets and guide tracks; and
movable means for terminating and securing the received at least one insulated wire in electrical connection with the first contact portion, wherein the means include at least a retaining bar over which the at least one insulated wire may be bent, wherein the movable means moves the received at least one insulated wire with respect to the housing.
