A representative embodiment of a terminal housing body for receiving a wire pair, the terminal housing body having a front end and a rear end, includes a base wall having a top portion. The terminal housing body also includes a channel formed in the top portion of the base wall for receiving the wire pair. The channel is adapted to guide the direction of the wire pair. The body further includes a plurality of wire guide posts extending from the top portion and joined by the base wall and running along opposing sides of the top portion of the base wall of the terminal housing body. Grooves separated by adjacent ones of the wire guide posts have openings into the channel for receiving the wires of the wire pair are also included in the body.
FIELD OF THE INVENTION The present invention relates to connectors for communication wires and cables, and particularly to a connector terminal housing in a communication jack assembly.
DESCRIPTION OF THE RELATED ART A compact communications jack connector is disclosed in U.S. Pat. No. 5,096,442 (issued Mar. 17, 1992). The known connector is formed from a unitary lead frame in which eight flat, elongated conductive elements connect spring jackwire terminals at one end of the frame with corresponding wire connection terminals at the other end of the frame. The wire connection terminals are insulation displacement connectors (IDCs) of the �slotted-beam� type. For example, see U.S. Pat. No. 3,027,536 (issued Mar. 27, 1962); U.S. Pat. No. 3,798,587 (issued Mar. 19, 1974) and U.S. Pat. No. 4,826,449 (issued May 2, 1989).
It is also known to construct a terminal post with a retaining portion formed of two arcuate spring members which are separated by an opening, thus resembling a �needle eye�. See, for example, U.S. Pat. No. 4,206,964 (issued Jun. 10, 1980). See also Design Patent No. 345,268 (issued Jan. 10, 1995) showing a telecommunications terminal clip having a slotted retaining portion. U.S. Pat. No. 4,136,628 (issued Jan. 30, 1979) and U.S. Pat. No. 4,262,985 (issued Apr. 21, 1981) show IDC terminals that are formed to be mounted inside of connector modules or housings.
SUMMARY OF THE INVENTION The present invention provides a terminal housing body for receiving a wire pair, the terminal housing body having a front end and a rear end, comprises a base wall having a top portion. The terminal housing body also comprises a channel formed in the top portion of the base wall for receiving the wire pair, the channel extending from the rear end toward the front end. The channel is adapted to guide the direction of the wire pair. The body further comprises a plurality of wire guide posts that extend from the top portion, are joined by the base wall, and ran along opposing sides of the top portion of the base wall from the rear end to the front end of the terminal housing body. Grooves separated by adjacent ones of the wire guide posts and having openings into the channel for receiving the wires of the wire pair are also included in the body.
DETAILED DESCRIPTION As will be described in greater detail herein, embodiments of the present invention can reduce the variability of the wire termination during installation of a communication jack. A reduction in variability of the wiring allows for the communication jack to provide reliable and consistent performance. Embodiments of the terminal housing body and the communication jack also allow for easier wire termination and thus easier installation of the jack.
The terminal contact wires 18 a-18 h have associated base portions 20 a-20 h opposite their free end portions. Each base portion is formed to connect a contact wire to one or more conductors on or within the wire board 12. For example, the base portions 20 a-20 h may be soldered or press-fit in plated terminal openings formed through the board, to connect with corresponding conductive paths on or within the board. The base portions 20 a-20 h project in a generally normal direction with respect to the top surface of the wire board 12. The base portions 20 a-20 h enter the wire board 12 with a �duo diagonal� footprint. In other embodiments of the connector assembly 10, the base portions of the terminal contact wires enter the wire board with a �saw tooth.�
The IDC terminal 200 also has a wire board mounting part 220 with a generally �needle-eye� appearance. The board mounting part 220 comprises opposed arcuate sections 222, 224 joined to the bottom edge 214 of the terminal by a common stem 226. The arcuate sections 222, 224 have an inner radius of typically about 0.083 inches and an outer radius of typically about 0.094 inches. The height of the �eye� opening defined between the sections 222, 224 is typically about 0.056 inches and the width of the opening about 0.014 inches. The width of the metal strips forming the sections 222, 224 is typically about 0.011 inches. The entire IDC terminal 200 including its base portion 204 and board mounting part 220 are preferably stamped from a single sheet of metallic material.
An important feature of the IDC terminal 200 is that its wire board mounting part 220 can establish reliable electrical contact with a plated opening 228 in the wire board 12, if the diameter of the opening 228 is slightly less than the overall width (e.g., 0.035 inches) of the �needle-eye� mounting part 220. That is, the mounting part 220 can be urged in the direction of the axis of the opening 228 to mount the terminal 200 on the board 12, and the arcuate sections 222, 224 are urged resiliently toward one another to maintain positive electrical contact with the plated wall of the board opening 228. A conductive path 230 on the board 12 which connects with the plating of opening 228, is thus electrically connected to the terminal 200. It has been discovered that no further bonding such as solder is necessary to maintain electrical contact between the terminal 200 and the conductive plating of the wire board opening 228.
The contact wires 18 a-18 h (See FIG. 1) and the IDC terminals 56 a-56 h are operatively mounted the wire board without the need for solder. The IDC terminals 56 a-56 h and contact wires 18 a-18 h have compliant �needle-eye� mounting parts that enhance their electrical connection with conductive paths on the wire board 12. The housing 50 when joined to the cover 60 engages shoulders 218 of the IDC terminals 200 and secures said terminals to the wire board.
The low-profile IDC terminal 200 disclosed herein is suitable for mounting on a printed wire board. The terminal 200 includes at least one shoulder 218 that not only assists in the insertion of the terminal into the wire board 12, but also cooperates with a part of the housing 50 to keep the terminal in place on the wire board when, for example, a wire is withdrawn out of the terminal. Although wires are not usually pulled out from IDC terminals, rearrangements are not uncommon. The mentioned �needle-eye� structure for the mounting part of the terminal 200 is a compliant structure that may be slightly larger than a plated wire board hole in which it is inserted. Because the terminal shoulder 218 cooperates with part of the housing 50 to hold the terminal in place, the terminal need not be soldered on the wire board.
While the foregoing description represents preferred embodiments of the invention, it will be obvious to those skilled in the art that various changes and modifications may be made, without departing from the true spirit and scope of the invention. Such modifications include, but are not limited to, the use of discrete components on the wire board 12 to reduce crosstalk, and the use of metallic terminal strips (e.g., �110� type connectors) preloaded into a dielectric housing prior to installation on the wire board.
