The wiring harness 16 in addition to being coupled to the landlines 18 and one or more components forming the electronics 14 of the monitoring device 20, is coupled to one or more sensors 19 that provide data relating to the utility usage and/or safety aspect information that is read by the monitoring device.
Referring again to
Seated within a secured bay 64 along an upper side 25B of the central panel are electronics 14A that support the monitoring device 20 and in the illustrated example embodiment of
The secured bay 64 forms a tamper-proof location for the electronics 14 of the monitoring device 20 between the central panel 25, cover 44, and sides 46 of the housing 22. In one example embodiment, the cover 44 is locked, preventing access to those without authorization. In the illustrated example embodiment of
The connector system 30 includes a connector body 31, body seal 32, contacts 33, lead seals 34, and wire leads 35, as illustrated in the exploded assembly views of
The connector body 31 in the illustrated example embodiment of
A two-stage diameter transverse channel 104 is formed in the neck 94 that extends to the head 92 of the connector body 31, which supports each of the wire leads 35, lead seals 34, and contacts 33. The channels 104 include a first opening 106 that extend through the connector body 31 transversely out a second opening 108 as best seen in the section views of
The contacts 33 include at a first end 112 (see
At a second end 118 (see
In yet another example embodiment, the conductive ends 122 are press fit into an m-shaped clasp 132 located at the first end of the contact 33 as best seen in
In one example embodiment, the contacts 33 are fabricated from a conductive material such as copper. In another example embodiment, the contacts are a purchased product. One suitable example of contacts 33 include Delphi Terminal Connectors sold by Delphi Packard Electric Systems under part number 120666643. The specification sheet for the Delphi Terminal Connectors is incorporated herein by reference. In another example embodiment, the lead seals 34 are made from rubber or elastomeric gasket material. One suitable example of lead seals 34 include Delphi Metricpack Terminal Seals 280 sold by Delphi Packard Electric Systems.
First and second arms 96 are symmetrically positioned about the head 92 of the connector body 31. The arms 96 provide a securing, yet selectively removable connection between the central panel 25 and the connector body 31, reassuring a signal generating connection is being made between the electronics 14 and wiring harness 16. More specifically, the arms 96 have pawls 135 that grasp corresponding catches 136 formed in a riser 138 that extends away from the lower side 25A of the central panel 25 as best seen in
By attaching the body seal 32 between the riser 138 and connector body 31, and not over the terminals 72 with a conventional gasket, the overall stack-up height of the connector system 30 is advantageously reduced. This allows for the connector system 30 to be used in applications where space, and in particular, height is limited. In one example embodiment, the height “H” as illustrated in
The low profile connection provided by the connection system 30 provides a method of disconnecting the harness 16 from the PCB 70 in a confined space when the height for an application is limited. The low profile characteristic is achieved by several of the features described throughout this disclosure, including for example, the transverse annular channel 104, the assembly forming the connector system 30, and the positioning of the body seal 32 about the connector body 31.
In the illustrated example embodiment of FIGS. 16 and 25-27, the connection system 30 is also advantageously field serviceable in that the wire leads 35 coupled to the wiring harness 16 can be disconnected from the enclosure by removing the connector body 31 from the terminals 72. The connector system 30 further advantageously provides a completely sealed system through the lead seals 34 and body seal 32, providing an environment to the electronics 14 free of moisture and/or debris. The sealed electronics 14 in the secure bay 64 opposite the primary bay 48 further provide an advantage of a safe tamper-proof security feature where the electronics are locked into the housing 22 and the monitoring device 20 can only be removed by disconnecting the connecting system 31.
The connector system 230 includes a connector body 231, body seal 232, contacts 233, lead seals 234, wire leads 235, locking arrangement 236, and conduit 237 as illustrated in the exploded assembly views of
The conduit 237 is a protective shroud or cover surrounding the wire leads 235 that can be stripped away from the lead ends upon connection. However, it should be appreciated that the connecting system 230 could be any number of wire leads 235 with or without the conduit 237 without departing from the scope or spirit of the present disclosure.
In the illustrated example embodiment of

A two-stage diameter transverse channel 304 is formed in the neck 294 that extends to the head 292 of the connector body 231, which supports each of the wire leads 235, lead seals 234, and contacts 233, as illustrated for example in
The contacts 233 include at a first end 312 having a square receipt 314 that includes an engageable center 316 comprising an m-shaped clasp 339 (see
The wire leads 235 pass through respective seals 234 before being crimped within respective m-shaped folds 320. Once the wire leads 235 are coupled with contacts 233 to have a conductive connection (reassuring a signal generating connection is made between the wiring harness 16 and PCB 70 when the connector body 231 is mated with the terminals 72) by for example crimping, the contacts 233, leads 235, and seals 234 are inserted into the first opening 306 within the neck 294 of the body 231.
The contacts 233 are positioned such that the square receipts 314 are positioned substantially centrally over the second opening 308 of the transverse channel 304. The contacts 233 bottom out against the inside of their respective transverse channel 304 through the first opening 306 in the direction of Arrow “B” in
The lead seals 234 and body seal 232 reassure that the electronics 14 remain free of moisture and debris. In the illustrated example embodiment, the wire leads 235 are 22 gage wire and the lead seals 234 are 22 gage insulated conductors forming a seal estimated to withstand IP67 requirements.
In one example embodiment, the contacts 233 are fabricated from a conductive material such as copper. In another example embodiment, the contacts are a purchased product. One suitable example of contacts 233 include Delphi Terminal Connectors sold by Delphi Packard Electric Systems under part number 120666643. The specification sheet for the Delphi Terminal Connectors is incorporated herein by reference. In another example embodiment, the lead seals 234 are made from rubber or elastomeric gasket material. One suitable example of lead seals 234 include Delphi Metricpack Terminal Seals 280 sold by Delphi Packard Electric Systems.
First and second snap wings 296 are symmetrically positioned about the head 292 of the connector body 231. The snap wings 296 provide a securing, yet selectively removable connection between the central panel 25 and the connector body 231, reassuring a signal generating connection is being made between the electronics 14 and wiring harness 16. More specifically, the snap wings 296 each comprise a channel opening 334 pawls 335 that grasp corresponding catches 336 formed in a riser 138 that extends away from the lower side 25A of the central panel 25 as best seen in
By attaching the body seal 232 between the riser 138 and connector body 231, and not over the terminals 72 with a conventional gasket, the overall stack-up height of the connector system 230 is advantageously reduced. This allows for the connector system 230 to be used in applications where space, and in particular, height is limited. In one example embodiment, the height “H” as illustrated in
Illustrated in
The locking arrangement 236 comprises a front 252, top 254, and first and second side 256, 258, respectively. The front 252 includes a plurality of arcs 260 corresponding to the number of openings 306 in the body 231. The locking arrangement 236, and in particular, the arcs 260 surround the seals 234 allowing only room for passing of the leads 235 when installed on the body as illustrated in
Located on a lower surface 262 opposite the top surface 254 are first and second bosses 264 that provide a first locking connection 265 with a catch 266 located on the top 250 surface of the body 231. Located on a back surface 268 of the front surface 252 are first and second posts 270. The first and second posts 270 provide a second locking connection 269 with the locking arrangement 236 and the body 231. Internal to the first and second sides, 256, 258, are arcuate regions 272 that form a third locking connection 273 with the locking arrangement 236 and the body 231.
During assembly, the wire leads 235 pass through their respective seals 234 and coupled (by for example crimping or soldering) to their respective conductors 233 to form a terminal assembly 280. Each terminal assembly 280 is seated into the respective first openings 306 of the body 231. The terminal assembly 280 is nested such that the receipts 314 are positioned substantially centrally over the second opening 308, allowing for proper alignment of the terminals 72 with respective receipts 314 when the body 231 is pushed or seated onto the riser 138 of the housing 22. Once the terminal assembly 280 is nested, the locking arrangement 236 is snapped into place forming a secured connection of the terminal assembly 280 within the body 231 by locking connections 265, 269, and 273 illustrated in
A technician may remove the locking arrangement 236, using for example, a screw driver. In an alternative example embodiment, not shown, the locking arrangement 236 rotates into a locked position via a live hinge assembly.
When the body 231 is seated on the riser 138, a secured connection 282 is formed allowing for signal generating coupling between the PCB 70, terminals 72, wire leads 235, and wiring harness 16. The secured connection 282 is maintained when the snap wings 296, and particularly the channel opening 334 pawls 335 that grasp corresponding catches 336 formed in the riser 138 that extends away from the lower side 25A of the central panel 25 as best seen in
The low profile connection provided by the connection system 230 provides a method of disconnecting the harness 16 from the PCB 70 in a confined space when the height for an application is limited. The low profile characteristic is achieved by several of the features described throughout this disclosure, including for example, the transverse annular channel 304, the assembly forming the connector system 230, and the positioning of the body seal 232 about the connector body 231.
