Definitions

  • the present invention relates to electrical connector assemblies employing insulation displacement type terminals and, more particularly, to connector assemblies of this type which can be used to mass terminate a plurality of insulated wires.
  • connectors of this type include a housing having one or more terminal , receiving cavities therein and a terminal mounted in the cavity.
  • the terminal has an insulation displacement slot for receiving a wire conductor. When the wire conductor is moved laterally of its longitudinal axis into this slot, the insulation is displaced so that the terminal electrically contacts the conductor.
  • United States Patent No. 4,262,984 shows a connector assembly for connecting an insulated wire conductor to another circuit member including a housing having a terminal receiving cavity therein, a terminal mounted in said cavity having an insulation displacement slot for receiving (and terminating) a wire conductor therein, and means for holding and locating a wire conductor in alignment over the slot of said terminal prior to connection thereto, whereby movement of said wire conductor laterally of its longitudinal axis into the slot causes displacement of the insulation so that the terminal electrically contacts said conductor; said holding and locating means comprises an upwardly facing, U-shaped clamp member having wire receiving area defined between two resilient legs, the legs position the wire conductor in the wire receiving area in the initial position and exert an inward lateral force against the insulated wire conductor when the wire is moved into the slot.
  • United States Patent No. 3,142,524 describes an insulation displacement connector for a pair of insulated conductors comprising a clamp member mounted for movement with the wire conductor from an initial position wherein the wire conductor is positioned over the terminal slot downwardly to a final position wherein the wire conductor is terminated.
  • the present invention is an electrical connector assembly for connecting an insulated wire conductor to another circuit member including a housing having a terminal receiving cavity therein, a terminal portion mounted in said cavity having an insulation displacement slot for receiving a wire conductor therein, and means for holding and locating a wire conductor in alignment over the slot of said terminal portion prior to connection thereto, whereby movement of said wire conductor laterally of its longitudinal axis into the slot causes displacement of the insulation so that the terminal portion electrically contacts said conductor, said holding and locating means comprising an upwardly facing, U-shaped clamp member having a wire receiving area defined between two resilient legs characterised in that said clamp member is mounted for movement with the wire conductor independently of the terminal portion, into the cavity alongside the terminal portion, from an initial position wherein said wire conductor is positioned over said terminal slot downwardly into the cavity to a final position wherein said wire conductor is terminated, whereby the legs position the wire conductor in the wire receiving area in the initial position and exert an inward lateral force against the insulated wire conductor when the clamp member is moved
  • FIG. 1 the connector assembly of the present invention, generally designated 10, is shown in Figs. 1 and 2.
  • the particular connector assembly 10 shown in the drawings is a splice connector for the purpose of connecting one set of insulated wire conductors 12 to another set of insulated wire conductors 14. It is understood that the connector assembly 10, which will be discussed in greater detail hereinafter, can be used to electrically connect an insulated wire conductor 12 with any other type of circuit element.
  • the connector assembly 10 is seen to generally include a housing, generally designated 16, which comprises a floor 18 (Fig. 2) surrounded by a pair of upstanding side walls 20 and a pair of upstanding end walls 22.
  • a plurality of cavities, generally designated 24a, 24b and 24c, are formed between the side walls 20 and are defined between the side walls 20 and a plurality of parallel intermediate spaced apart upstanding barrier walls 26.
  • Each cavity 24a, 24b and 24c has pairs of opposing vertical channels 28 and 30 formed in the barrier walls 26 or side walls 20. Each cavity 24a, 24b and 24c also includes an opening 34 in the end walls 22 at opposite ends thereof. Slots 36 (Fig. 2) are formed in the floor 18 of each cavity 24a. 24b and 24c for purposes which will become more apparent hereinafter.
  • each cavity 24a, 24b and 24c has a metal terminal, generally designated 40 mounted therein.
  • Each terminal 40 has two upstanding wire connecting plate portions 42 integrally joined by a horizontal portion 44.
  • Each wire connecting portion 42 has a pair of bosses 46 formed on either side thereof.
  • each wire connecting portion 42 has a conventional insulation displacement slot 50 (Fig. 3) formed therein for receiving a wire conductor 12 or 14 therein.
  • Each terminal 40 is mounted in its respective cavity 24a, 24b and 24c by sliding motion. This is accomplished by the cooperation of bosses 46 within channel 28 to guide and locate the terminal within its cavity.
  • holding and locating means in the form of an upwardly facing, U-shaped clamp member, generally designated 56.
  • the clamp member 56 may be stamped from metal or formed from plastic.
  • the clamp member 56 has a horizontal bight portion 58 with two resilient legs 60 extending upwardly therefrom at an outward angle as best seen in Fig. 3.
  • the region in between legs 60 defines a wire receiving area which is adapted to receive wire conductor 12 or 14.
  • Opposing protrusions 62 are formed on the innersides of the free ends of legs 60.
  • the area between protrusions 62 defines an entrance which is constricted relative to the remaining width of the area between legs 60.
  • the width of the entrance is not greater than the diameter of the insulated wire conductor.
  • the clamp member 56 is mounted for movement into a cavity 24a, 24b or 24c by providing a pair of opposing bosses 64 formed on either side of the clamp member 56. Bosses 64 are received within channels 30 in each cavity 24a, 24b and 24c. As the clamp member 56 is moved downwardly in channels 30, the legs 60 move toward one another as indicated by the arrows in Fig. 3. The legs 60 of clamp member 56 exert an inward lateral force against the insulation of the insulated wire conductor 12 or 14 as it is moved from the initial position shown in Fig. 3 to a final position as shown in Fig. 4.
  • clamp member 56 act as a strain relief against accidental axial pull out.
  • clamp members 56 move the wire conductor 12 or 14 with it as it is moved from its initial position to its final position.
  • connector assembly 10 provides the slot 36 for the purpose of permitting a thin flat blade of a tool (not shown) to push up against the bottom of the bight portion 58 of clamp member 56. When this occurs, the clamp member 56 pops upwardly releasing the wire conductor 12 or 14 without destroying terminal 40.
