In Fig. 4, the first end structure indicates that with 14.1 it comprises an elongated cannula-like part 104, and an end of this part has one, and the other end has an outwardly directed flange along circumferential interior outstanding flange, and it has a sagittal plane and a frusto-conical surface.The remainder of this first end structure is the same with the form of the structure 14 of Fig. 1.First end structure 14.1 and sleeve pipe 106 usefulness folder encircle surely 90 and clamping ring 98 link together.
Can also do the modification of variety of way to end construction 14 and 16.An alter mode as shown in Figure 5.In this form, end cap 105 has the disc end wall 110 of an atresia when initial die casting.In order to insert pipe fitting (being equal to pipe fitting 52), on end wall 110, hole, (112 among the figure) passes through from the hole pipe fitting.Can pipe 112 and wall 110 be fixed with ultrasonic bonding or other means then.Then thermal contraction sheath 114 and 116 is fixed on the relative end of pipe 112, forms resin mass 118 again.An outer stalk is preferably arranged on the pipe fitting, and as 112.1 among the figure, abutment walls 110 makes the pipe fitting location.
In the form of Fig. 6, pipe 120 has external screw thread, with two nuts 122 and 124 and have the wall 110 of boring to fix.In this form, the resin mass 118 that adds is not only the part of sheath, and nut 124 is imbedded.
If needed, can be with the heat shrink material end cap 32 integral injection moldings.The sheath 52.1(of whole die casting sees Fig. 7) thin-walled arranged.The length of thin-walled sheath 52.1 equals the sheath 36 and 38 and manage 52 total length among Fig. 1.In this embodiment, need not use sheath 36,38.Two ends of thin-walled sheath 52.1 enlarge its diameter with mechanical means, shown among the figure 52.2 after die casting.Out-of-date when cable is pushed away from the thin-walled sheath, cable has quite tight cooperation in interlude, then is loose fit in the both ends that enlarge.
In case cable C1 was pushed away from the thin-walled sheath, to the two ends heating of thin-walled sheath, thereby also shrink on cable equally with sheath 36,38 end of thin-walled sheath, has shunk on cable.
Be understandable that the modification among Fig. 5 to 7, be not only applicable to end construction 14, and be applicable to end construction 16.
Though at the cable C1 shown in the above picture and text, C2 and C3 are oversensitive pressurization telephone cables, also may be used for described not pressure cable connector lug, and optical fiber cable, coaxial cable (data transmit and use) power transmission cable etc.Can also be used to be marked with the cable of vaseline.
