Abstract

An electrical connector including a circuit board, a contact spring insert, and an insulation displacement terminal insert wherein the contact spring insert is positioned between the insulation displacement terminal insert and the circuit board. The insert assembly can be mounted to a jack housing to form a telecommunications jack for receiving telecommunications plugs.

Claims

1. A jack for use with a mounting fixture having a jack opening, the jack comprising:

a) an insert assembly including;

i) a contact spring insert including a plurality of flexible contact springs held relative to one another;

ii) a separate insulation displacement terminal insert including a main body with a first side and a second side with an insulation displacement terminal housing positioned at the first side and a central opening for receiving the contact spring insert, the insulation displacement terminal housing including a plurality of terminals, separate from the contact spring insert;

iii) a circuit board wherein the contact springs and the terminals are electrically linked through the circuit board and wherein the contract spring insert is positioned in the central opening of the main body of the insulation displacement terminal insert and the circuit board is positioned at the second side of the main body;

b) a jack housing configured to be mounted within the jack opening of the mounting fixture, the jack housing including a first retaining structure positioned opposite from a second retaining structure, the first and second retaining structures being positioned to engage a front side of the mounting fixture when the jack housing is mounted in the jack opening;

c) wherein the jack housing includes a resilient cantilever member having a base end positioned opposite from a free end, the base end being integrally connected with the jack housing, the cantilever member including a retaining tab positioned near the free end of the cantilever member, the retaining tab being positioned to engage a back side of the mounting fixture when the jack housing is mounted in the jack opening;

d) wherein the jack housing includes a front portion positioned opposite from a back portion, the front portion defining an inner chamber and also defining front and rear openings for accessing the inner chamber, the front opening comprising a port sized for receiving a plug, and the back portion of the jack housing defining an open channel that extends in a rearward direction from the front portion, the jack housing adapted to receive the insert assembly in the open channel, the jack housing including a base and two opposite facing side walls, the base and the side walls defining at least a portion of the open channel;

e) wherein the insert assembly includes a snap-fit connection structure positioned at the main body for securing the insulation displacement terminal insert to the jack; and

f) wherein the insert assembly includes longitudinal guides, the jack housing including mating longitudinal guides for slidably mating with the longitudinal guides of the insert assembly, wherein the longitudinal guides of the jack housing are offset from the base so that alignment of the insert assembly within the jack housing is not dependent on a surface of the insert assembly engaging the base.

2. The jack of claim 1, further including a second resilient cantilever member including a retaining tab positioned to engage the back side of the mounting fixture, the second cantilever member positioned on an opposite side of a front of the jack housing.

3. The jack of claim 1, wherein the main body of the insulation displacement terminal insert includes structure at the first side of the main body for retaining the contact spring insert in the central opening of the main body.

4. The jack of claim 1, wherein the snap-fit connection structure includes two flexible lever members, the locking tabs defined on the flexible lever members, and the contact springs are positioned generally in a region between the flexible lever members.

5. The jack of claim 4, wherein the jack housing includes a hole in each of the sidewalls to receive one of the locking tabs.

6. An insert assembly for a telecommunications jack, the jack including longitudinal guides and being for use with a plug having plug contacts, the insert assembly comprising:

a) an insulation displacement terminal insert having a main body including a front portion with sidewalls positioned opposite from a back portion, the insulation displacement terminal insert including;

i) longitudinal guides for slidably mating with the longitudinal guides of the jack, the longitudinal guides of the insulation displacement terminal insert being defined by the sidewalls at the front portion of the main body;

ii) a snap-fit connection structure positioned at the main body for securing the insulation displacement terminal insert to the jack, the snap-fit connection structure being defined by the sidewalls at the front portion of the main body;

iii) an insulation displacement terminal housing positioned adjacent the back portion of the main body, the insulation displacement terminal housing including a plurality of insulation displacement terminals housed therein;

b) a contact spring insert including a plurality of contact springs held by the contact spring insert, the contact spring insert being positioned generally between the sidewalls adjacent the front portion of the main body of the insulation displacement terminal insert;

c) a circuit board providing electrical connection between the insulation displacement terminals and the contact springs.

7. The insert assembly of claim 6, wherein the snap-fit connection structure for securing the insulation displacement terminal insert to the jack is integrally formed with the longitudinal guides of the insulation displacement terminal insert.

8. The insert assembly of claim 6, wherein the snap-fit connection structure includes two flexible lever members each having a locking tab.

9. The insert assembly of claim 6, wherein the main body of the insulation displacement terminal insert defines a central opening adjacent the front portion of the main body between the sidewalls for receiving the contact spring insert.

10. The insert assembly of claim 6, wherein, once positioned between the sidewalls of the main body of the insulation displacement terminal insert, the contact spring insert does not extend forwardly past the front portion of the main body.

11. A method for assembling an insert assembly for a telecommunications jack comprising the steps of:

providing a circuit board including electrical tracings thereon;

providing a contact spring insert including contact springs with spring tips;

providing an insulation displacement terminal insert including terminals with terminal tips, the insulation displacement terminal including a main housing with a first side positioned opposite a second side, and a central opening for receiving the contact spring insert;

positioning the contact spring insert within the central opening of the main housing;

positioning the circuit board at the second side of the main housing, with the spring tips and the terminal tips projecting into the circuit board;

mounting the contact spring insert and the insulation displacement terminal insert to the circuit board.

12. The method of claim 11, wherein the step of mounting the contact spring insert and the insulation displacement terminal insert to the circuit board includes the step of soldering the spring tips and the terminal tips to the circuit board.

13. The method of claim 11, further comprising the step of sliding the insert assembly into a jack housing to form a telecommunications jack.
