Definitions

  • This invention relates to connectors and, more particularly, to RJ type female connectors and to methods of making the same .
  • an RJ female connector device has a front keyed opening which matches the outline of the male connector to be attached.
  • Common examples are the connections on all telephones that accept the cable that runs from the phone body to the hand piece or accepts the wire that runs from the phone body to the wall.
  • RJ connectors come in various sizes, RJ 6, RJ 11 etc., and will have a different number of contacts for the male to connect to, however, the keyed entrance opening remains the same for a particular series, RJ6, for example, no matter how many contacts are inside.
  • the present invention is directed to RJ connectors and methods of assembly which address the foregoing problems, while also providing substantial cost savings and improved performance. More specifically, the present invention is directed to RJ type female connectors which offer substantial savings in both material costs, assembly costs, and overall space requirements. In addition, since the invention permits substantially shorter contact wires than current constructions, unwanted inductive parasitics are reduced and cross talk at high frequencies is also reduced, a tremendous advantage for the high speed data transmission systems .

  • Fig. 13 illustrates a method of forming a plurality of pin support sections.
  • the invention contemplates both discrete RJ connectors which will be described in connection with Figs. 1-lOb and in-situ RJ connectors which will be described in connection with Figs. 11-13.

  • the first pin section 11 has a first group of four pins 16 and the second pin section 12 has a second group of four pins 16.
  • the sections 11 and 12 have opposing surfaces with respective matable projections 11a, 12a and grooves lib, 12b which enable the sections to connect to one another in interlocking fashion.
  • the respective pins 16 are bent, as shown in Fig. 2b, so that when the sections 11 and 12 are connected to each other the upwardly extending portions of the pins 16 interdigitate with one another and lie essentially in the same plane, as shown in Fig. 2c.
  • the housing 13 includes an opening 17 having a shape complementary to a male RJ connector (not shown) . Additionally, as seen in Fig. 3, the housing 13 has means, such as ledges 13a and sidewalls 13b (only one of each being shown in Fig. 3) , 9/54967
  • a metal shield 14 may be provided. In such a case, the housing 13 snaps into the metal shield 14, as shown in
  • a support 18 such as a printed wiring board having openings for receiving the legs 20 of the connector, the legs 14a of the shield and the depending portions of the pins 16 and for providing the necessary electrical interconnections .

  • the interlocked pin sections 11 and 12 are first assembled to the support board 21 and then the support board with the pin sections mounted thereon is assembled into the housing 13 and the housing then inserted into the metal shield 14.
  • Figs. 6 and 7 show the combined RJ connector and electronics assembly and a support 22 having holes for receiving the depending elements thereof.
  • FIG. 8a-Fig. 8c An alternative embodiment of the pin support sections, 11 and 12, designated 11' and 12', is shown in Fig. 8a-Fig. 8c. Like the sections 11 and 12 of Figs. 2a-2c, the sections 11' and 12' are molded parts.
  • the pins 16 in the embodiment of Figs. 8a-8c are, as shown in Fig. 8a, initially disposed at an angle rather than vertically. This results in different bending of the pins, as shown in Fig. 8b, to achieve the necessary orientation so that, as shown in Fig. 8c, the upper portions of the pins lie in a common angular plane after assembly of the sections 11' and 12' to each other with the lower portions disposed vertically.
  • Another difference is the use of complementary shaped, opposing surfaces rather than matable projections and grooves to position and interlock the sections 11' and 12' to each other.
  • FIGs. 9a-9c A still further embodiment is shown in Figs. 9a-9c.
  • a single molded or machined block is used with the pins inserted in the block in a separate step .

  • Figs. 10a and 10b shows 4 leads per group in the lead frame 30, the number of leads per group will depend on the number of leads associated with a particular RJ connector.
  • this aspect of the invention contemplates the following inventive features: first, developing an RJ female connector by molding pins in interlocking sections to achieve proper alignment and then combining the molded sections with a housing having an entry to align and lock the male connector. Second, the overall design that combines the above concept with various circuit combinations for filtering or other electronic treatment of incoming or outgoing signals.
  • a user incorporates the contacts or leads as part of a standard assembled PC board to be mounted in a metal frame or enclosure (not shown) , along with the simple and expensive molded plastic insert (box 31) described above that snaps and locks into a square hole in the metal frame .
  • Method 1 is the one which would be used for assembly of a complete circuit .
  • Method 2 is a prepackaged system for use by others who would do the assembly.
  • Method 1 - This method is illustrated in Fig. 11. Although the illustration shows a plurality of leads 32 folded, they would be automatically inserted vertically into tight fitting holes in two parallel staggered rows in a printed circuit board 33 to be later soldered to pads (not shown) on the under side of the board 32 along with other components.
