  • DE 1,277,975 discloses a device for parallel connection of cables, which comprises multiple sections.
  • US 3,340,352 discloses a connector assembly having a plurality of connector elements.
  • none of these prior art compression connectors have a first collapsible link positioned between the first and second tap wire ports, and a second collapsible link positioned between the third and fourth tap wire ports.
  • none of these prior art compression connectors have a first angled crumple zone positioned between the first and second side tap wire ports, and a second angled crumple zone positioned between the third and fourth side tap wire ports.
  • the compression connector has a first pair of slots extending between the first section and the second section on a first side thereof, and a second pair of slots extending between the first section and the second section on a second side thereof.
  • the first and second pairs of slots are capable of receiving a cable tie for securing wires therein before crimping.
  • a compression connector for securing wires therein.
  • the compression connector has a first body portion connected to a second body portion.
  • Each of the body portions has a hook and a ramp extending therefrom to form a first main wire port, and a hook and a ramp extending therefrom to form a second main wire port.
  • Each of the body portions further has two side tap wire ports, and an angled crumple zone defined between the two tap wire ports.
  • the compression connector has a first pair of slots extending between the first and second body portions on a first side thereof, and a second pair of slots extending between the first and second body portions on a second side thereof.
  • the first and second slots are capable of receiving a cable tie for securing wires therein before crimping.
  • each of the side tap wire ports is positioned between a hook and a ramp. Moreover, each of the side tap wire ports are substantially the same size. Alternatively, each of the side tap wire ports are a different size.
  • Fig. 1 to 12 illustrate examples which do not form part of the invention but which are useful for understanding the invention.
  • FIGS. 1-6 are directed to a compression connector 20
  • FIGS. 7-12 are directed to a compression connector 120
  • FIGS. 13-19 are directed to a compression connector 220.
  • FIG. 1 shows a split multi-tap compression connector 20 secured around main line wires 22 and tap wires 24, 26, after crimping.
  • compression connector 20 is a one-piece member made of electrically conductive material, such as copper.
  • compression connector 20 may be made of any suitable materials or elements that will withstand a crimping operation.
  • compression connector 20 has a first section 28 and a second section 30.
  • first section 28 includes a first body portion 32 having a hook 34 and a ramp 36 extending therefrom to form main wire port 38 in which main line wires 22 can be placed.
  • hook 34 is C-shaped.
  • First section 28 has a first end wall 40 connected to first body portion 32. Tap wire ports 42, 44 are adjacent first end wall 40, and retention tabs 46, 48 extend from first body portion 32 at an oblique angle. Groove 50 is positioned between retention tab 46 and ramp 36, and groove 52 is positioned between retention tab 48 and hook 34. Collapsible link 53 connects first body portion 32 and first end wall 40, and is positioned between tap wire ports 42, 44.
  • Retention tabs 46, 48 increase the overall compressibility of compression connector 20 because tap wire ports 42, 44 can accommodate different size tap wires 24, 26. As shown in FIG. 6, tap wire ports 42, 44 can accommodate large and small diameter tap wires 24, 26. Retention tab 46 minimizes the gap between first end wall 40 and first body portion 32 to improve the positioning and enhance the retention of tap wire 24 in tap wire port 42, before and during the crimping operation. Likewise, retention tab 48 minimizes the gap between first end wall 40 and first body portion 32 to improve the positioning and enhance the retention of tap wire 26 in tap wire port 44, before and during the crimping operation. Preferably, tap wire ports 42, 44 are teardrop-shaped. As best seen in FIG. 3. tap wire port 42 is larger than tap wire port 44. However, as shown in FIG. 8, tap wire ports 42, 44 may be the same size.
  • Second section 30 is identical to first section 28.
  • second section 30 includes a second body portion 54 having a hook 56 and a ramp 58 extending therefrom to form main wire port 60 in which main line wires 22 can be placed.
  • hook 56 is C-shaped.
  • Second section 30 has a second end wall 62 connected to second body portion 54.
  • Tap wire ports 64, 66 are adjacent second end wall 62, and retention tabs 68, 70 extend from second body portion 54 at an oblique angle.
  • Groove 72 is positioned between retention tab 68 and ramp 58, and groove 74 is positioned between retention tab 70 and hook 56.
  • Collapsible link 75 connects second body portion 54 and second end wall 62, and is positioned between tap wire ports 64, 66.
  • a central body portion 76 connects first body portion 32 and second body portion 54.
  • compression connector 20 includes two slots 78, 80 cut through compression connector 20. Slots 78, 80 provide space to loop a cable tie (not shown) to secure main line wires 22 and tap wires 24, 26 to compression connector 20 before crimping.
  • FIGS. 1-6 show compression connector 20 having slots 78, 80, it is likewise contemplated that compression connector 20 may not have any slots.
  • FIGS. 7-12 A second example is illustrated in FIGS. 7-12.
  • a split multi-tap compression connector 120 is substantially the same as compression connector 20 illustrated in FIGS. 1-6, except the tap wire ports are substantially the same size.
  • compression connector 120 functions similarly to compression connector 20 illustrated in FIGS. 1-6.
  • C-shaped compression connector 20 allows for partial hands-free installation because hooks 34, 56 can be hung around main line wires 22 while tap wire 24 is inserted into tap wire ports 42, 64, and tap wire 26 is inserted into tap wire ports 44, 66.
  • Main wire port 38 and one of tap wire ports 42 or 44 must be utilized. The remaining tap wire port 42 or 44 may be utilized or left empty.
  • main wire port 60 and one of tap wire ports 64 or 66 must be utilized. The remaining tap wire port 64 or 66 may be utilized or left empty.
