Definitions

  • This invention relates to the art of electrical connectors and, particularly, to a single-pole plug connector for a shielded cable including a signal wire or conductor, an insulating jacket and an outer shielding.
  • the invention is particularly applicable to coaxial cables.
  • a coaxial cable connector is known (US Patent 5,116,230) which has dielectric means for mounting a signal terminal that terminates to a signal wire and conductive grounding terminal means arranged outside the dielectric means having piercing means to engage an outer shielding of the coaxial cable.
  • the coaxial cable connector discloses an outer insulating housing for mounting a plurality of terminals for a plurality of coaxial cables.
  • Single-pole plug connectors are a mass-produced item that are manufactured in many different configurations. There is therefore an ongoing need to cost-effectively produce such single-pole plug connectors with existing assembly machines, while maintaining a properly designed quality product.
  • An object of the invention is to provide a new and improved single-pole plug connector for terminating a shielded insulated wire or coaxial cable which can be produced inexpensively with existing assembly machines.
  • the single-pole plug connector of the invention includes a hollow shielding sleeve of metal which constitutes the outer housing of the single-pole plug connector, and a hollow insulating insert housing which mounts a hollow signal terminal.
  • the outer housing or sleeve includes a free cavity and collapsible insulation piercing means for cooperation with the shielding and insulating jacket of the coaxial cable.
  • the signal terminal is of the insulation displacing or piercing type and is activated when the insert housing is fully inserted into the outer housing or shielding sleeve. Simultaneously, when terminating the signal wire, the piercing means of the outer housing or shielding sleeve bites into the jacket of the coaxial cable to make a connection therebetween.
  • hollow shielding sleeves are produced from a single metal sheet in such a way that they remain attached to the sheet metal strip from which they were produced in order to be fed in to an assembly machine in rolled reels where the sleeves can be separated or cut from the reels.
  • the collapsible insulation piercing means is located in the interior of the shielding sleeve along with the hollow, insulating insert housing.
  • the insert housing is preferably a two-part structure including a terminal housing member and an actuating housing member. A signal terminal is inserted between the terminal housing member and the actuating housing member and, together with the insert housing, is pre-assembled in the shielding sleeve.
  • the shielding sleeves, together with the pre-assembled insert housings and signal terminals remain on the residual portion of the sheet metal strip and can be rolled up.
  • Final assembly of the plug connector is effected by introducing the shielded cable into the shielding sleeve with the signal wire or conductor passing into the hollow signal terminal and the cable shielding passing into the collapsible piercing means.
  • Final assembly is effected by axially pressing the parts together, thereby crimping the signal terminal which clamps and engages the signal wire.
  • the outside of the insulating insert housing is provided with grooves having abutment surfaces and the wall of the shielding sleeve may be provided with ridges or tabs, which engage each other and hold the parts firmly in position.
  • Figure 1 shows the components of a plug connector 10 for a shielded cable 1 which includes a signal wire or conductor 2, a cable shield 3 , an inner jacket 4 and an outerjacket 5.
  • the plug connector itself includes a hollow shielding sleeve 11, a terminal housing member 12 and an actuator housing member 13 which together form an insert housing, and a signal terminal 14.
  • the signal terminal can have a female socket configuration (as shown) or a male pin configuration.
  • the walls of the shielding sleeve 11 are stamped out of a metal sheet and formed into shape.
  • the shielding sleeves remain connected to a residual sheet metal strip or carrier 15 so that the sleeves can be easily handled during assembly of the plug connector.
  • the carrier 15 includes transport and indexing holes 16.
  • Opposing edges of the sheet metal from which the shielding sleeve is folded are configured as shown at 17 and 18. These interleaved portions 17 and 18 engage one another with an undercut configuration, so that some tensile loading in the peripheral direction of the shielding sleeve 11 is carried by the sleeve.
  • the insert housing made up of terminal housing member 12 and actuator housing member 13, is generally hollow and is fabricated of insulating material such as plastic.
  • the terminal housing member and the actuating housing member have external grooves with abutment surfaces 25, 26 and internal cavities or spaces 27, 28 which form through passages.
  • Signal terminal 14 also has a hollow configuration with a through passage and includes a collapsible plug portion 21 having termination engagement means 24, and a signal contact portion 22 which connects with the plug portion at a step or shoulder 23.
  • the collapsible plug portion fits into cavity 27 in terminal housing member 12 and signal contact portion 22 fits into cavity 28 of actuating housing member 13.
  • Shielding sleeve 11 comprises a first section including two clamp portions 30 having insulation piercing means 31, and a second section including a free cavity 32 for receiving insert housing 12,13 and signal terminal 14. Ridges or tabs 35, 36 are formed in the wall of the shielding sleeve 11 and form abutment surfaces to latchingly interengage with abutment surfaces 25, 26 of the insert housing. As seen in Figure 2, in this pre-assembled condition the rear end of the insert housing projects out of the shielding sleeve.
  • shielded cable 1 is inserted into the opening formed between the insulation piercing means 31, and the pre-assembled structure of Figure 2 is compressed by applying pressure, with a tool for example, to the rear end 29 of the insert housing to push it further into the sleeve.
  • Signal terminal 14 is thereby terminated.
  • This causes each limb of clamp portion 30 to be shortened and insulation piercing means 31 thereby penetrates outer shielding 3 of cable 1 and makes contact with the shielding.
  • Ribs or actuating projection portions 33 disposed on actuating housing member 13 cooperate with the abutment surfaces 23 of signal terminal 14.
  • actuating projection portions 33 penetrate into cavity 27 of terminal housing member 12 which is enlarged at an opening thereof in a funnel-shape configuration.
  • Collapsible portion 21 of signal terminal 14 includes termination engagement means 24 which penetrate the insulating jacket of cable 1 and makes contact with signal wire 2.
  • the position of the insert housing may be secured by ridges or tabs 37, 38 on the wall of shielding sleeve 11, which engage the abutment surfaces of terminal housing member 12 and actuating housing member 13, respectively.
  • FIG. 5 shows a perspective view of plug connector 10 prior to assembly to the cable 1.
  • shielding sleeve 11 is generally rectangular or square shaped, either of which is desirable in terms of manufacture of insulation piercing means 31.
  • the force applied to rear end 29 of the insert housing can be measured by a suitable force-measuring device on the assembly tool, and it is possible to determine whether the thrust force is in the correct range. If the dimensions are not correct and/or the cable is not correctly inserted, the measured force will be outside the permissible range, and faults can therefore be detected and corrected.
  • the step of separating the shielding sleeve from the carrier strip may be effected prior to or after completion of the assembly procedure.
