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. An insert assembly for a telecommunications jack for use with a plug having plug contacts, the insert comprising:

a) an insulation displacement terminal insert having a main body including a first side positioned opposite from a second side, the insulation displacement terminal insert including;

i) a snap-fit connection structure positioned at the main body for securing the insulation displacement terminal insert to the jack;

ii) an insulation displacement terminal housing positioned at the first side of the main body;

iii) a plurality of insulation displacement terminals housed by the insulation displacement terminal housing, the insulation displacement terminals each including a tip positioned at the second side of the main body;

b) a contact spring insert including a plurality of contact springs held by the contact spring insert, the contact spring insert including a first side positioned opposite from a second side, the contact springs including contact portions positioned at the first side of the contact spring insert for engaging the plug contacts of the plug, the contact springs each including a tip positioned at the second side of the contact spring insert;

c) a circuit board providing electrical connections between the tips of the insulation displacement terminals and the tips of the contact springs, the circuit board being mounted adjacent to the second side of the main body and the second side of the contact spring insert.

2. The insert assembly of claim 1, wherein the snap-fit connection structure includes two flexible lever members each having a locking tab, and the contact springs are positioned generally in a region between the flexible lever members.

3. The insert assembly of claim 1, wherein the contact spring insert defines an outer surface, wherein the outer surface is positioned between the circuit board and a portion of the main body.

4. The insert assembly of claim 1, wherein the main body defines a central opening for receiving the contact spring insert.

5. 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 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 between the insulation displacement terminal insert and the circuit board;

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 locking tabs, the jack housing including a hole in each of the sidewalls to receive one of the locking tabs;

f) wherein the insert assembly includes outwardly facing slots, the jack housing including guide rails for receipt in the slots of the insert assembly, wherein the rails 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.

6. The jack of claim 5, 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.

7. 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;

positioning the contact spring insert between the insulation displacement terminal insert and the circuit board, 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.

8. The method of claim 7, 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.

9. The method of claim 7, further comprising the step of sliding the insert assembly into a jack housing to form a telecommunications jack.
