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. 1 is an exploded perspective view of a connector in accordance with an embodiment of the present invention.
- Figs. 2a, 2b and 2c are perspective views showing stages in the assembly of pin support section forming parts of the connector of Fig. 1.
- Fig. 3 is a cross-sectional view of the connector of Fig. 1 after assembly thereof.
- Fig. 4 is a perspective view of the connector of Fig. 1 along with an electro-magnetic shield and a printed wiring board into which the connector is to be inserted.
- Fig. 5 is an exploded view of an alternative embodiment of a connector in accordance with the present invention.
- Figs. 6 and 7 are a perspective view and a cross-sectional view, respectively, of the connector of Fig. 5 after assembly thereof and a printed wiring board into which the connector is to be inserted.
- Figs. 8a, 8b and 8c show stages in the assembly of an alternative embodiment of a pin support section.
- Figs. 9a and 9b show another alternative embodiment of a pin support section in accordance with the present invention.
- Figs. 10a and 10b illustrate a method of manufacturing a pin support section.
- Fig. 11 illustrates an embodiment of a connector formed in-situ in accordance with the present invention.
- Figs. 12a and 12b are top and side views, respectively, of pin support sections used to form an in- situ connector.
- Figs. 12c and 12d are top and side views, respectively, of an alternative embodiment of pin support sections used to form an in-situ connector. 4 -
- 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.
- a discrete RJ female connector 10 in accordance with the present invention comprises three molded parts - a first molded pin support section 11, a second molded pin support section 12 and a molded housing 13 - and a metal shield 14.
- 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 .
- FIG. 5-7 An alternative embodiment of the connector is shown in Figs. 5-7, in which the housing 13 is extended so as to accommodate both the first and second pin sections 11 and 12 and an electronic assembly 19, such as a magnetic filter comprised of a printed wiring board and associated electronic components, such as toroids, mounted on a support board 21, such as a printed wiring board having openings for receiving the depending portions of the pins 16 and for providing the necessary electrical interconnections.
- an electronic assembly 19 such as a magnetic filter comprised of a printed wiring board and associated electronic components, such as toroids, mounted on a support board 21, such as a printed wiring board having openings for receiving 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 .
- a plurality of pins 16 are first inserted into a block
- FIG. 10a and 10b An alternative method of manufacturing the pin support sections 11, 11', 12 or 12' is shown in Figs. 10a and 10b.
- a lead frame 30 having groups of leads 31 supported by rails 32 is employed.
- the lead frame 30 is fed into a molding press (not shown) which molds the support sections (11, 11', 12 or 12') about the leads 31.
- the sections with the molded-in leads are then severed from the rails 32 of the - 7
- 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.
- RJ connectors are used with a printed circuit board with many components constituting a particular circuit.
- the particular circuit developed is generally contained in a molded enclosure and the input signals or output signals or both are made through female RJ connectors .
- the molded enclosure includes a square opening to match the outside dimensions of the RJ connector.
- a keyway 30 for an RJ male connector (Fig. 11) , rather than the square opening, is formed in an enclosure 31 (Fig. 11) , thereby eliminating the need for a separate RJ enclosure. This does not add an additional component since it is just a hole in the box of a different shape.
- the keyway 30 has the necessary guides 8 -
- 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.
- the leads 32 are folded after final board assembly. Alternatively, pushing on the box 31 can fold the leads 32 automatically.
- Method 2 - This method is illustrated in Figs. 12A - 12D. More specifically, Figs. 12A and 12B show top and side views, respectively, of a molded strip 40 into which staggered rows of pins (leads) 32 are inserted like in Method 1 in sections 41. The pins 32 would then be folded to the necessary angle and supplied to the customer to insert and solder to a printed circuit board.
- the sections 41 are formed in multiples that can be broken apart into either single or multiple - 9 -
- Figs. 12C and 12D the assembly is provided with pins 32 actually molded into the strip 50 so no insertion is required. Feeding two rows of wire into a mold at different levels to develop the staggered effect would be most difficult and costly.
- two separate sections, 51 and 52, having saw tooth shaped facing sides 53 would be bonded together after molding. The molded saw tooth sides 53 assure proper alignment.
- Fig. 13 shows how a plurality of strips 50 would be molded in one shot.
- the bonded together sections 51, 52 incorporate molded projections to assure proper alignment with the box 31.
- this aspect of the invention contemplates the following inventive features: first, developing an RJ by inserting the pins in a board, printed circuit or a plain board, and combining it with an entry to align and lock the male connector. This entry could be an integral part of the assembly or supplied separately. Second, the concept of the leads encased in a single or bonded pair of molded strips rather than the board, again to be combined with a separate or integral entry. Third, the overall design that combines the above concept with various circuit combinations for filtering or other electronic treatment of incoming or outgoing signals.
