Puller for clamping rails "for longitudinal locks of cable fittings

The innovation "refers to a puller for clamping rails for longitudinal locks of cable fittings.

A wide variety of closure organs are known in socket technology; with the problem of sealing in the foreground. So in most of the palls, sealants are used in the levels of separation inserted, some of which are pressed together with considerable pressure by appropriately designed sealing elements. Such sealing organs can be, for example, planes molded onto the sleeve body, between which a plastic one Sealant is inserted. The required sealing force through which the sealing compound is evenly distributed in such a way that no more air inclusions are present, means on the Churning acting press screws reached. Another closure possibility is that along the sleeve body the dividing line beads are formed, over which adapted clamps are pressed. The beads can, however, as from the DT-OS 2 158 992 is apparent, also covered with rails and pressed together. The application of rails across in the longitudinal direction uniformly formed beads are extremely difficult because very large forces have to be applied, to slide the rail over the entire sealing area. For this reason, the beads, as well as the clamping rails wedge-shaped along the dividing line of the socket body

forms. In this way, the clamping rails can be placed on the sealing area of the beads without any effort. The further compression is then carried out by pushing on again the clamping rails over the wedge-shaped beads, whereby the force is evenly distributed over the entire area due to this design distributed and done at the same time. However, the effort required for this is considerable, so that suitable tools are required. There is also the risk that due to the wedge-shaped training the clamping rails slide off, which would reduce the closing pressure. This was remedied by the German Utility model * 76 20 440 reached, in which at least one expression is arranged in the top side of the EL clamping rail, the has such a width that a tightening strap can be drawn in. Just as the drawing up of such a klesam splint prepares even pulling off significant difficulties. So far, the clamping rails have been removed with an opening wedge and a hammer Beading of the cable fitting released. In the case of tightly fitting, with sealant glued clamping rails, this method is associated with particular difficulties, with a considerable risk of injury for fitter and cable set.

The task of the innovation is to use the tools commonly used for pulling up the clamping rails and with to create an auxiliary device suitable for pulling off the existing features of the clamping rails. The task at hand will be now solved according to the! inflation that a support block a perpendicular repelling abutment and two also in the same Direction deflecting! Has guide legs, and that in the upper region of the support block with a transverse support groove a Pührungsdurchbruch is arranged.

The essence of the innovation is that the wedge-shaped clamping rail, which is firmly seated on the beads of the cable set, has a Tension band, as it is also used for pulling up, and with a known pulling tool over the pulling device according to FIG the innovation can be deducted. This puller is designed in such a way that it pulls itself off against the head of the cable set.

supports, with a protection against tipping by vertical repellent Legs, which are supported on the socket shell, reached will. The tightening strap, which is sram pull-off, is guided and secured through the embossing in the clamping rail, is removed after it has been inserted detected in the guide opening of the extraction block from the extractor. This pulling tool is supported during the pulling process in a support groove against the puller, whereby the clamping rail is loosened and finally pulled off.

The innovation will now be explained in more detail with the aid of five figures. Figure 1 shows a cross section through the puller.

FIG. 2 shows the side of the pulling device facing the pulling tool.

Figure 3 gives a top view of the puller.

FIG. 4 shows a slight modification of the puller according to FIG.

Figure 5 shows the use of the puller again.

FIG. 1 shows the section I-I indicated in FIG. From this the support block 1 can be seen, which has the perpendicularly repelling abutment 4, with which it is against the cable set head supports. Furthermore, one of the two guide legs 2 can be seen in this illustration, which is during the removal process is supported on the socket shell and thus tilting of the puller as a result of the tensioning of the tensioning band acting torque prevented. The forces acting in this case are applied over a large area to the sleeve wall by the guide legs 2 transfer. In the upper area of the support block 1, the guide opening 3 can be seen through which the tensioning band δ is led to the pulling tool. In order to prevent the pulling tool from slipping off, a guide groove 5 is arranged in to which the guide tool is attached. Figure 2 shows the

the side facing the pulling tool, with the in the guide groove 5 arranged guide opening 3 can be seen particularly clearly. On both sides of the support block 1 are the two Guide leg 2 can be seen. FIG. 3 shows a plan view on the pulling device, whereby the arrangement of the two guide legs 2, which are supported on the socket shell 6 during the pulling process, emerges. In addition, this is also the abutment

4 recognizable, which must be designed in its length so that the distance between the support block 1 and the cable set head is sufficient, to get the clamping rail 7 completely free of the beads.

FIG. 4 shows the pull-off device in a slightly modified form according to Pigur 2. Here, only the guide opening is shown • held open at the top so that the tensioning strap can be inserted from above to pull off the clamping rail. The support groove 5 and all other features of the puller are retained. Finally, FIG. 5 shows the use of the puller shown during the pulling process. From this it can be seen that one end of the tensioning band 8 is in the expression 9 the clamping rail 7 is inserted and the other end through the guide opening 3 in the support block 1 to the pulling tool to be led. The tensioning band 8 is first introduced in the expression 9 in the reverse direction and is then over the Expression 9 bent back. The strap is secured against slipping through a pin 10 attached to the end - '* - ■' 25 secures. This just described pulling the tensioning band 8 into the expression 9 is a certain distance and a parallel guidance to the clamping rail 7 is achieved, whereby the acting torque is reduced. In addition, supporting the Abutment 4 on the cable set head and the support of the guide legs 2 can be seen on the socket shell 6. On the back of the support block 1, the pulling tool 11 engages in the Support groove 5 and is thus secured against slipping.
