Description
7719P ' mi: The invention concerns improvements in or relating to an electrical, connector having a terminal portion for crimping connection to a conductor wire, such a connector being described and claimed in our British patent no, 1,053,083 (F018) or our Israeli applSioa&on no. 28,321 (¾¾2D . The invention is particularly concerned with the strain relief of the crimped connection of such a connector and a conductor wire, especially one having a thin insulating sheath„ An electrical connector, according to the invention, comprises a crimping ferrule received within a metal sleeve extending rearwardly of the ferrule, a conical funnel extending from the rearward end portion of the metal sleeve towards the ferrule with the narrower end of the funnel penetrating the rear end of the ferrule.
The funnel may be an integral extension of the rearward end portion of the metal sleeve or it may be discrete from the metal sleeve and located within the connector by engagement with a shoulder formed in the rearward end portion of the metal sleeve,, In the latter case the funnel may be of metal or synthetic resin., Preferably, the narrower end of the funnel is received within the rear end portion of the ferrule0 The invention includes a crimped connection of an electrical connector of the invention and a sheathed conductor wire having an exposed free end portion which is received in the crimping ferrule with the sheathed portion of the conductor wire received in the funnel, the ferrule being deformed by crimping into engagement with the ex osed conductor and the funnel into en a ement with the sheathed portion of the conductor wire., The invention will be described by way of example with reference to the accompanying drawings, in which:- Figure 1 is a partial sectional view of a connector and a sheathed conductor wire before crimping; Figure 2 is a view as Figure 1 of the connector after crimping; Figure 3 is a perspective view of a strip of conical funnels; and Figure 4 is a view as Figure 1 of another connector.
The connector of Figures 1 and 2 comprises a terminal portion 1 press-fitted within the forward end portion of a metal sleeve 2 within an insulating sleeve 3„ The terminal portion 1 comprises a crimping ferrule portion 4 and an integral ring tongue portion 5 extending forwardly of the sleeves 2,3. The ferrule portion 4 has a conductor-receiving bore 6 formed with annular grooves 7. The rearward end of the ferrule portion 4 has a tapered rearward entrance 8. The rearward end portion of the metal sleeve 2 is of wider diameter than the forward end portion and the free end is inturned to double thickness at 9. The free end of the folded portion is serrated at 10 for engagement with the insulating sheath 11 of a sheathed conductor 12 of a conductor wire0 The insulating sleeve 3 is press-fitted to the metal sleeve 2 and has a rearward end portion of expanded diameter „ A conically shaped funnel 13 is located between the folded portion 9 and the tapered entrance 8 of the ferrule portion 4. The wall of the narrower end of the funnel 13 is of reduced thickness for penetration of the tapered entrance 8 and the wider end has an outturned rim 14 for snap engagement with the serrated free edge 10.
The funnel 13 may be drawn with others from flat metal strip. The formed strip, Figure 3 , comprises elongate lateral bars 15 having longitudinally spaced apart formed funnels 13 joining the bars 15 by strap portions 16 . The formed strip may be fed automatically to machinery for sequentially severing individual funnels 13 and assembling each with the other parts of a connector. The other parts are preassembled by inserting the terminal portion 1 into the sleeves 2 and 3 which are pre-indented at Γ7 to limit insertion of the terminal portion 1.
In use, insulating sheath is stripped off the free end portion of an insulated conductor wire 11 to expose the conductor 12 which is advanced into the connector from the rearward end. The conductor 12 is funnelled towards the bore 6 of the ferrule portion 4 by the funnel 13.
The free edge of the insulating sheath 11 engages the funnel wall to limit forward insertion and the serrated edge 10 engages the sheath 11 to limit rearward withdrawal. The formed assembly is then crimped about the ferrule portion 4 , and between the folded portion 9 and the indentation 17 to the condition shown in Figure 2 to form a secure mechanical and electrical connection0 The deformed funnel 13 strain relieves the connection of the connector and conductor wire.
The funnel 13 of the connector of Figure 4 is an extension of the folded portion 9 of the metal sleeve 2.
The funnel 13 may be formed of synthetic resin to form a waterproof seal. The terminal portion 1 may have a second crimping ferrule portion 4 instead of the ring tongue portion 5 illustrated in Figure 1, so forming a splice connector. The connector may be used to terminate conductor wires having a thick insulating sheath by abutting the free edge of the insulating sheath adjacent the outturned rim 14 „ -6- 54159/2
Claims (7)
1. An electrical connector comprising a crimping ferrule received -withi a metal sleeve extending rearwardly of the ferrule, a conical funnel extending from the rearward end portion of the metal sleeve towards the ferrule with the narrower end of the funnel penetrating the rear end of the ferrule.
2. A connector according to Claim 1, in which the funnel is an extension of the rearward end portion of the metal sleeve.
3. A connector according to Claim l,in which the funnel is discrete from the metal sleeve and is located within the connector "by engagement with a shoulder formed in the rearward end portion of the metal sleeve.
4. A connector according to Claim 3, in which the discrete funnel is composed of synthetic resin.
5. crimped connection of an electrical connector according to any of Claims 1 to 4 and a sheathed conductor having an exposed free end portion which is received in the crimping ferrule with sheathed portion of the conductor wire received in the funnel, the ferrule being deformed by crimping into engagement with the conductor and the funnel into engagement with the sheathed portion of the conductor wire.
6. An electrical connector, substantially as described with reference to any of Figures 1 to 3 or 4.
7. A crimped connection of a conductor wire and an electrical connector substantially as described with reference to Figure 2. Por the Applicants DR. BS:ed
