Configuring electrical signal distribution networks can be done by selecting from a suite of standard elements. For example, a vendor can provide a suite of different length cables, different types of connectors, etc. The specific requirements of the electrical signal distribution network can be met by selecting, from this suite of standard elements, those that most closely approximate these specific requirements. Because such suites of standard elements is finite, no suite can optimally meet the specific requirements of any electrical signal distribution network.
Another method of configuring an electrical signal distribution network is to custom build such a network. For example, and electrical signal distribution network can be constructed by cutting specific lengths of wire, and soldering these custom lengths of wires to connectors, other wires, or other elements of the electrical signal distribution network. Such customization is often performed by professionals trained in such arts.
Apparatus and associated methods relate to a bridge/splitter connector for configuring an electrical signal distribution network. The bridge/splitter connector includes a body block, and first and second cable retention members. The body block includes first and second cable channels. The first cable channel is located on a first side of the body block. The first cable channel is configured to receive a first multi-conductor flat cable therewithin. The first cable channel has a first plurality of conductive piercing members laterally spaced apart from one another within the first cable channel. Each of the first plurality of conductive piercing members configured to pierce insulation of the first multi-conductor flat cable received within the first cable channel so as to conductively contact a corresponding one of a first plurality of conductive wires of the first multi-conductor flat cable. The second cable channel is located on a second side of the body block. The second cable channel is configured to receive a second multi-conductor flat cable therewithin. The second cable channel has a second plurality of conductive piercing members laterally spaced apart from one another within the second cable channel. Each of the second plurality of conductive piercing members is configured to pierce insulation of the second multi-conductor flat cable received within the second cable channel so as to conductively contact a corresponding one of the second plurality of conductive wires of the second multi-conductor flat cable. Each of the first plurality of conductive piercing members of the first cable channel is conductively coupled to a corresponding one of the second plurality of piercing members of the second cable channel. The first cable retention cover is configured to removably engage the body block. The first cable retention cover is further configured to expose the first cable channel when removed and to retain the first multi-conductor flat cable received within the first cable channel when engaged with the body block. The second cable retention cover is configured to removably engage the body block. The second cable retention cover is further configured to expose the second cable channel when removed and to retain the second multi-conductor flat cable received within the second cable channel when engaged with the body block.
Some embodiments relate to a method for configuring an electrical signal distribution network. The method includes exposing, via removal of a first cable retention cover from a body block, a first cable channel located on a first side of the body block. The method then receives, via the first cable channel located on a first side of a body block, a first multi-conductor flat cable therewithin. Then, the method pierces, via a first plurality of conductive piercing members laterally spaced apart from one another within the first cable channel, insulation of the first multi-conductor flat cable received within the first cable channel so as to conductively contact a corresponding one of a first plurality of conductive wires of the first multi-conductor flat cable. Then the method retains, via engagement of the first cable retention cover to the body block, the first multi-conductor cable within the first cable channel. The method includes exposing, via removal of a second cable retention cover from a body block, a second cable channel located on a second side of the body block. The method then receives, via a second cable channel located on a second side of a body block, a first multi-conductor flat cable therewithin. Then, the method pierces, via a second plurality of conductive piercing members laterally spaced apart from one another within the second cable channel, insulation of the second multi-conductor flat cable received within the second cable channel so as to conductively contact a corresponding one of a second plurality of conductive wires of the second multi-conductor flat cable. Then the method retains, via engagement of the second cable retention cover to the body block, the second multi-conductor cable within the second cable channel. Each of the first plurality of conductive piercing members of the first cable channel is conductively coupled to a corresponding one of the second plurality of piercing members of the second cable channel.
Apparatus and associated methods relate to a bridge/splitter connector for configuring an electrical signal distribution network. The bridge/splitter connector includes a body block and two cable retention covers, each configured to removably engage the body block. The body block has two cable channels, each configured to receive a multi-conductor flat cable therewithin. Each cable channel has a plurality of conductive piercing members laterally spaced apart from one another for piercing insulation of the multi-conductor flat cables received so as to conductively contact a corresponding one of a plurality of conductive wires of the multi-conductor flat cable. Each of the plurality of conductive piercing members of each cable channel is conductively coupled to a corresponding one of the plurality of piercing members of the other cable channel, The cable retention members are configured to retain the multi-conductor flat cables received within the cable channels when engaged with the body block.
Each of bridge/splitter connectors 12 is configured to mechanically and electrically connect a first multi-conductor flat cable with a second multi-conductor flat cable. Furthermore, each of the first and second multi-conductor flat cables can extend either from one end or from two ends of the bridge/splitter connector 12, to which the first and second multi-conductor flat cables attach. For example, if both first and second multi-conductor flat cables extend from only one end (perhaps from opposite ends), then bridge/splitter connector 12 would function as a splice connector. If, however, a first multi-conductor flat cable extends from both ends of bridge/splitter connector 12, but a second multi-conductor flat cable extends only from one end of bridge/splitter connector 12, then bridge/splitter connector 12 would function as a tap connector. If both first and second multi-conductor flat cables extend from both ends of bridge/splitter connector 12, then bridge/splitter connector 12 would function as a bridge connector. In this way, bridge/splitter connector 12 can function as any of these three different types of connectors—splice, tap, or bridge. Bridge/splitter connectors 12, as well as 10 mm wire-piercing bulbs 20 and C9 faceted wire-piercing bulbs 22, can connect to cable sections 26 at any location along a length of multi-conductor flat cables as will be described in more detail below.
First and second end cavities 34A and 34B are contiguous with first and second cable channels 32A and 32B, respectively. Cut ends of the first and the second multi-conductor flat cables are configured to be received within first and second end cavities 34A and 34B, respectively, while the other ends of the first and the second multi-conductor flat cables pass through first and second cable channels 32A and 32B, respectively, and extend from body block 28. In the depicted embodiment, end cavities 34A and 34B are configured to receive cut ends of multi-conductor flat cables in a direction perpendicular to that of a longitudinal direction that portions of the multi-conductor flat cables that are retained within first and second cable channels 32A and 32B. Cut ends of the first and/or the second multi-conductor flat cables are received within first and second end cavities 34A and 34B only if such first and/or second multi-conductor flat cables are configured to extend only from one end of body block 28.
If, however, first and/or second multi-conductor flat cables are to extend from both ends of body block 28, then first and/or second removable tabs (e.g., knock-outs) 36A and/or 36B are removed from body block 28, so as to permit such a configuration. first and second removable tabs 36A and 36B are removably attached to body block 28. In some embodiments, when first and/or second removable tabs 36A and/or 36B are removed, they are removed in such a manner that doesn't permit re-attachment of first and/or second removable tabs 36A and/or 36B. In other embodiments, first and/or second removable tabs 36A and/or 36B are configured to be re-attached if needed.
Within first cable channels 32A are first plurality of conductive piercing members 38A and 40A. Similarly, within second cable channels 32B are second plurality of conductive piercing members 38B and 40B. Bridge/splitter connector 12 of the embodiment depicted in
First and second pluralities of conductive piercing members 38A and 40B are configured to pierce insulation of the multi-conductor flat cables received within first and second cable channels 32A and 32B, respectively. Such insulation is pierced so as to provide conductive contact between each conductive piercing member of first 38A and 40A and second 38B and 40B pluralities of conductive piercing members and a corresponding one of first and second pluralities of conductive wires 44A and 44B of first and second multi-conductor flat cables 26A and 26B, respectively. In some embodiments, each of first and second pluralities of conductive piercing members 38A and 40B are blades aligned with a longitudinal axis of the first and second cable channels, respectively. In other embodiments, each of first and second pluralities of conductive piercing members 38A and 40B are blades aligned with a transverse axis of the first and second cable channels, respectively.
After the multi-conductor flat cables are received within first and second cable channels 32A and 32B, first and second cable retention covers 30A and 30B can be returned to their engagement positions with body block 28. In some embodiments, the act of engaging first and second cable retention covers 30A and 30B can force the multi-conductor flat cables received within first and second cable channels 32A and 32B into first 38A and 40A and second 38B and 40B pluralities of conductive piercing members, respectively, thereby causing conductive contact between each conductive piercing member of first 38A and 40A and second 38B and 40B pluralities of conductive piercing members and corresponding conductors of the multi-conductor flat cables received within first and second cable channels 32A and 32B, respectively. Each of first plurality 38A and 40A of conductive piercing members of first cable channel 32A is conductively coupled to a corresponding one of second plurality 38B and 40B of piercing members of second cable channel 32B. In this way, each of conductors of the multi-conductor flat cable received within first cable channel 32A is conductively coupled to a corresponding one of the conductors of the multi-conductor flat cable received within second cable channel 32B.
Furthermore, in some embodiments, the multi-conductor flat cables received within first and second cable channels 32A and 32B are secured within first and second cable channels 32A and 32B, via various retention features. For example, first and second cable channels 32A and 32B and/or first and second cable retention covers 30A and 30B can include frictional surfaces or features, such as, for example, ridges, for inhibiting longitudinal translations of first and second multi-conductor flat cables 26A and 26B with respect to first and second cable channels 32A and 32B, when first and second cable retention covers 30A and 30B are engaged with body block 28.
