Abstract

Cable feed-through strip (10, 12) with at least two cutouts (30, 32, 34) that can be operatively connected and face each other for cable parts (14, 16), of which the strip part (16) has barbs (48) with projections (42) has, while the other strip part (14) has the barbs (48) receiving recesses (44) so that two strip parts (14, 16) can be detachably connected to each other, characterized in that the distance (a) of the barb (48) from the end face (43) of the last part carrying it is greater than the distance (b) of the undercut (46) from the end side of the last part facing the barb (48).

Description

  • The invention relates to a cable grommet according to the preamble of claim 1.
  • Cable entry strips are a combination from cable clamp rails and clamping profile. On the one hand, they offer one Safe, fast strain relief for the suspended cables or lines and secondly, optimal tightness. An important technical The advantage, however, is the divisibility of the lasts, which makes subsequent Installation of fully assembled cables or lines is made possible. Here, the cable grommet has several Holes for receiving cables with different diameters. If not all holes are needed, it is possible, insert blind plugs here. However, it is a cable entry bar with a variety of shots, then inserting the cables into the bar in that the cables become difficult during the assembly process can detach from the bar.
  • So was already in the DE 85 02 271 U1 described a cable entry plate, the mutually facing and interconnectable strip parts can be connected by means of snap connections. The locking connections consist of locking strips and locking recesses, which are designed and dimensioned so that an operational connection between two strip parts can only be produced if they are arranged at a distance from each other. This makes it difficult to correctly attach cables between the strip parts.
  • Based on the above state of the Technology is the object of the invention to remedy this create.
  • The object is achieved according to the invention solved the features of claim 1.
  • It can be seen that the invention in any case is realized if it is a cable grommet acts in which those that are not yet operatively interconnectable Strip parts can be arranged at a defined distance from each other can, making sure that the cables are always between the welt parts and the welt parts detachable with each other, but are captively connected.
  • Further expedient and advantageous configurations the invention emerge from the subclaims.
  • A particularly useful design stipulates that the The pre-assembly connecting body one piece formed with the last parts or are separate parts. It is it is expedient if the The pre-assembly connecting body as a plug or receptacle are formed, whereby these parts during the manufacturing process of the welt parts can be manufactured.
  • Another expedient embodiment sees before that The pre-assembly connecting body as molded projections or recesses are formed, the projections of the one strip part in the recesses of the assigned other The last can be inserted.
  • To use the strips for a variety of cables to be able sees a further practical embodiment the invention that between the Strip parts at least one intermediate piece with corresponding recesses for the Cable can be ordered. The individual parts can be releasably connected to the pre-assembly connecting bodies. A operational connection between the individual parts of the strip is advantageously achieved by that the Recesses as through openings are formed in the connecting bodies, e.g. Screws can be inserted are. Finally sees an advantageous measure the invention that connecting piece both ledges and also has recesses.
  • An embodiment of the invention is shown schematically in the drawing and is described below explained in more detail. It demonstrate
  • 1 , the assembly of a cable grommet,
  • 2 a cable grommet with an intermediate piece,
  • 3 this in 2 illustrated intermediate piece and
  • 4 the part marked IV 1 shown enlarged.
  • In the 1 and 2 is a cable entry system 10 . 12 with two operationally connectable and facing recesses 30 . 32 . 34 for cord parts with cables 14 . 16 shown. The welt parts 14 . 16 are approximately mirror images and provided with circular arc-shaped recesses, which in the assembled state (cf. 1c ) Define openings in which cables, not shown, are held. In the upper area there is a molding 14 a label 15 , The label field ( 15 ) is designed in the form of a recess into which at least one label can be clipped. The recess has neat cuts. The last 70 and 12 have pre-assembly connectors 40 , in the 4 are shown in more detail. Through this body 40 can the welt parts 14 . 16 be positioned at a distance from each other, as in 1b is shown. The pre-assembly connector body 40 are one-story with the welt parts 14 . 16 trained and procured as plug or receptacle. In the present exemplary embodiment there are the pre-assembly connecting bodies 40 from a molded projection 42 and a recess 44 , with the projection 42 one part of the strip 16 into the assigned recess 44 the other part of the strip 16 is insertable. The lead 42 has two barbs on its free end 48 on that in the recesses 44 with corresponding undercuts 46 intervene and their distance a from the front 43 a multiple, here 14 times, of the distance b of the undercut 46 from the front 45 is. In general, this distance a can also be smaller or even larger and can be, for example, 20 or 30 times b. The tabs 42 are slotted in their longitudinal direction so that they can be pivoted relative to one another, which is when the projection is introduced 42 into the opening 44 is important because the width of the inlet opening is determined by the distance between the undercuts 46 defined by each other. By the length of the protrusions 42 is the distance between the strip parts 14 . 16 defined by each other (cf. 1b ). After inserting the lead 42 into the recess 44 the tabs relax 42 and take that in 1b position shown. By moving the skirt parts further 14 and 1b towards each other then the in 1c shown position reached.
  • In the 1 Cable bushing shown has two pre-assembly connecting body 40 , which are arranged at the ends. The assembly and assembly of the cable entry bar 10 to 1 is carried out as follows:
    The two parts as in 1a are connected to each other as in 1b is shown. The barbs 48 are with the undercuts 46 operationally connected, and the openings that the respective recesses 30 . 32 . 34 are significantly larger than the outer circumference of the cable to be accommodated. Then the cable is inserted and provided with slotted cable sleeves, which are arranged in the recesses. If all recesses have been fitted with cables, then the strip parts will be 14 . 16 pressed against each other, as in 1c shown and provided with screws through the through openings 44 be performed. In the area below 39 the head of the screw is sunk while in the recess 37 the mother can be accommodated. Should the cable entry bar 12 can be used for several cables, then the in 1 shown bar by means of at least one intermediate piece 20 , this in 3 is shown, equipped and expanded. The intermediate piece 20 also has protrusions 42 and recesses 44 that with the welt parts 14 . 16 are operationally connectable. It is therefore a bar whose individual parts can be connected to one another in a modular manner. From the above description it can be seen that a bar theoretically with a variety of different intermediate pieces 20 can be equipped, the main commonality of which is that they have the same pre-assembly connecting bodies 40 as well as recesses 44 are provided. The diameter of the recesses 30 ' . 32 ' . 34 ' can vary.
