![]() Cable ties for mounting cables against a panel
专利摘要:
A cable tie (l) with devices (2) (3) (4) (l7) (l8) for forming a loop, intended for mounting cables (6) against a single panel (7) or a marking plate (l9). The cable tie has an integrated panel anchor (8) consisting of a longitudinal axis of a long narrow body parallel to the long side of the band longitudinal cross-section in the vicinity of the panel anchor. The cable tie changes direction in the integration point (ll) for straps and panel anchors. The panel has an opening (9) whose shape is the sum of a circle (12) and an elongated opening (13). Mounted so that the straps are pressed together (Figure 6) around the panel anchor, whereby the panel anchor is mounted (Figure 7) in through the long-narrow opening (l3). Then the entire cable belt is rotated 90 ° (Figure 8) around the axis of the circular part (l2) of the panel opening. When the strip is then released (Figure 9) to its original shape, the outer parts of the top of the panel anchor are fixed to the back of the panel and the strip pops side of the panel anchor is fixed to the front against continued rotation at the ends of the long narrow opening. 公开号:SE1230082A1 申请号:SE1230082 申请日:2012-08-22 公开日:2014-02-23 发明作者:Jan Berglund 申请人:Inco Innovation; IPC主号:
专利说明:
is slightly thinner, this to better control was the bandbends during assembly. The connection between the strap and the anchor isalso slightly submerged into the anchor to extend itthe thinner part that bends so that it can adapt more easilyfor different panel thicknesses. This is to avoid thatstress the plastic by too sharp bends of the band inthat area. Nylon, which is often used for cable ties, has onetendency to crack if stressed hard in combinationwith low humidity. The nylon picks up and gives offwater in line with the humidity and in the middle of winter canthere will be problems in the northern latitudes if you stress ittoo hard when bending it. The direction of the long narrow opening is chosen so that it isperpendicular to the direction of the cables,hoses or pipes to be attached to the panel. When assembling, bend the strap in the area closestthe anchor in such a way that the anchor can be inserted intothe panel opening without the band in the vicinity bending againsttoo much. First, insert the long, narrow body of the anchorthrough the long narrow opening of the hole until the body liescompletely on the back of the panel. Then you rotate the wholethe cable belt 90 ° clockwise or counterclockwise around its axiscircular part of the panel opening and release. Bandetscurves near the anchor now strive, to regain itsoriginal shape and this causes the band to foldthe ends of the elongate opening and so onprevents further rotation. In this position sitsthe cable tie quite loose but still completely locked in all directionsplus rotation. When then the cable tie is tightened around the cablesthen the whole area around the anchor and its longitudinal narrow is stretchedbody is pressed against the back of the panel and then it is fixed. The distance between the anchor and the cable tie locking function shouldnot be too large for it should not exceed the perimeteron the smallest cable to be bundled. To further improve the robustness of the assembly canto let parts of the elongated body protrude into itcircular hole. This is to prevent movement atstrong vibrations. These parts can advantageously be shortcircle segments that may protrude into the panel openingcircular del. This strengthens the fixation of movements insame plan as the panel. It also has a relieving effectso as not to bend the thinner portions closest to the anchorneed to be exhausted by small bends if the anchor can movealong the back of the panel in strong vibrations. The panel thickness for one and the same cable tie can be in onerange, approximately 1-4mm. When the panel is thick, so be italso an advantage if you make a bevel on the edges of the openingtowards the front of the panel, at least on the circular part. Having a thicker panel can also be an advantagethat the central hole is drilled slightly larger and that itthe long narrow opening may be slightly longer than on a thinner onepanel. In these ways, the range of panelthicknesses that a single cable tie fits. Another advantage of this type of panel anchor is thatit is also suitable for panels that are not flat. Archedplates, which is common in machines, cars,airplanes etc are no obstacle, and this works of the samereason that it can handle panels with differentthicknesses.The opening in the panel can also be advantageously drawn so that itcan be created with three boreholes, two small holes that are drilled firstand then a large one in the middle. Alternatively, you can punchor mill forward the opening, even the bevel at thickerpanels can be made in a punch if it is not too large. It should be entirely possible to drill the three holes completelycare if needed supplemented in the field because it does notsome greater accuracy is required on the positions between the holes. MANcan use a drill template to make it easier. Onesuch, for example, could first guide the drill so that the two small holesgets the right position and size, then gets another part ofthe drill template help to place the large hole in the middlebetween. There is nothing to prevent you from using thiscable ties even when it is not to be mounted against a panel. MANcan for example imagine using this cable tie for marking,eg text information or symbols. Then you make a traywhich has an opening as described above and which in additioncontains text or other information. You then assemblethe cable tie in the tray in the same way as in the panel above andthen you tighten the cable tie around what is to be marked. Hereone can also imagine a variant of cable ties with twoanchors, one for panel mounting and one for mounting onemarker. The cable ties are easy to manufacture as an injection molded part,a simple tool without movable jaws. The panel anchor can, of coursebe a bit bulky for the handling in that theyeasier to get stuck in each other and it can also be a bitmore difficult to package the cable ties in a simple way. Perhapsyou can injection mold a whole row of cable ties that sit togetherwith small bridges that bend or twist off during use. Oneway could be to injection mold a large number of cable tiesplaced in the tool in the form of a star or a fanwith the anchors outward. This collection can then sit together foreveruntil the user breaks a band foruse. Because these parts are normally manufactured invery large series, you also want for that reasonmanufacture in multi-compartment tools. The management for the usercan probably if not otherwise be solved with some type of holder ascan hold together a larger number of cable ties and that at the same timemakes it easy to take one out without getting stuck in anythingof the others.Although one type of cable tie can handle several panel thicknessesit may be that you want to manufacture a number of different onessizes, colors, an extra robust variant or a doublevariant for both panel mounting and marking. Possibly tooa variant for really thick panels and / or for reallarge loops. In any case, it should not be neededespecially many different types and the chance is quite high thatyou can manage with only one type when, for example, you have to run cablesin a machine of some kind. STATE OF THE ART AND PROBLEMS SOLVED BY THE INVENTIONPlastic cable ties, usually Nylon, are an accepted onetechnology for attaching things to. The big advantage isthat they are very robust and that the loop that is formed isflexible in size so that the same type of cable ties canbe used even if there are varying sizes of it asbundles. But if, for example, you want to attach a cable bundle to something like thatdo you want to be able to thread the cable tie around this something. When toattach something to a panel, such as a plate, you can make twoholes in the plate and then thread the cable tie into one andthen again in the other to then fasten the loop aroundtex a cable. One problem here is that you do not always cometo the back of the plate. In machines of various kinds it isusually the wiring is done against a chassis orsimilar and then it is often impossible to access wooda cable tie in through a hole in some machine part and thenout again. With the present invention and in particularshaped the hole in the same machine part, you only insert onesmall part of the cable tie through the hole and twist the wholecable ties 90 °. Then form a loop around the cable andtightens just as usual. A variant of existing cable ties has a snap functionto snap into a round or square hole, see e.g.Franks Patent WO2005 / 099402. These are usually adapted toa special panel thickness, but there are variants that areadapted for two different thicknesses by having doublesnap functions at different depths. Those who snap into a roundholes lack a stop against rotation. These variants can bedifficult to disassemble without access to the back of the panelbecause you normally have to squeeze the snap from the back atdismantling. However, there are variants that can be dismantledfrom the front, but then the snap and the locking mechanism have often becomequite large so that the cable no longer abutspanels. When the cable or cable bundle comes out fromthe panel, the robustness becomes significantly worse andthe resistance to vibration decreases drastically. Oftechnical reasons (EMC), it is a great advantage thatlet electrical cables lie near metal plates, it preventsthat they have antenna-like functions that can interfere with orcapture disturbances with the environment. Another type ofpanel mounting for cable ties is so-called tree mounting, they have oneprotruding mechanism that is like a stem with a varietybranches in decreasing size, similar to an upside down turnChristmas tree. The whole mechanism is pushed into a hole so thatthe branches are deformed and the mechanism gets stuck in the hole. Thistype is independent of the thickness of the panel and can also fit indifferent hole sizes but it is not very robust againstvibrations and can be easily released if exposedtensile forces. A similar variety has the function of a plastic rivetintegrated with the cable tie, a two-part body is fittedthrough a hole in the panel and then insert onethird body in between so that the two previous ones are bent outthe sides on the back of the panel. These are robust but lastof two parts and is therefore more expensive to manufacture andassemble. Furthermore, there are variants that have a surface coated withadhesive to glue the cable tie to the panel ininstead, or a hole to screw it to the panel. Alternatively, you can glue, or screw a smaller onedetail with small loops on which the cable tie can then be fastenedi. The disadvantage of adhesive is that it is difficult to findthe balance between being tight enough andthat they should be possible to disassemble. Over time,also glues a tendency to dry and lose itsadhesion, especially in hot environments such as in machines. The variants with screws are very robust but require thateither thread directly into the panel if it is thick enough orassembles gang inserts. The downside here is that it will bemore time-consuming, to both create the thread and then to screwfixed cable ties. To just punch holes, albeit a little complexsuch are very cheap and are made completely automatically. In summary, it can be said that existing cable ties haveoften one or more of the following disadvantages:l.10. Difficult to mount against a panel if you do not haveaccess to the back of the panel. Difficult to disassemble from a panel if you do not haveaccess to the back of the panel.Are only adapted to one, or a couplepanel thicknesses. Protrudes too much from the panel. Impairs the EMC properties of the cable assembly. Lacks locking to prevent the cable tierotates in the hole. Has adhesive that dries and comes off over timeand / or are difficult to disassemble. Can not withstand strong vibrations. Requires threads that make the panel more expensive and are moretime consuming to assembleConsists of two details which increases the price. The above points are also the problems of this inventionaddresses and claims to be the solution to.
