Abstract

The lock spring (1) comprises a pair of spring legs (4,5) and can be installed in a sleeve for accommodation of an electric cable to prevent withdrawal of the cable. It has a pair of cutting edges (6,7) which penetrate the cable to retain it. The spring has at least one locating area (10) for limiting the penetration depth of the cuttig edges, so that they do not cause a short circuit in the cable.

Description

Patentkrav: 1. Låsefjeder til en kanal for optagelse og fiksering af rør eller kabler med en indføringsretning, hvor fjederen er fjedrende når røret eller kablet bevæges i indføringsretningen, og hvor fjederen skærer sig ind i røret eller kablet når dette bevæges imod indføringsretningen, samt hvor fjederen har et fjederben, som vender imod røret eller kablet, og som har en skærekant, kendetegnet ved, at fjederbenet har mindst et anlægsområde til anlæg mod kablet for begrænsning af skærekantens skæredybde. 2. Låsefjeder ifølge krav 1, kendetegnet ved, at fjederen har et andet fjederben, som er sammenhængende med og danner en vinkel med nævnte første fjederben, hvor det andet fjederben er indrettet til at blive fastholdt i kanalen. 3. Låsefjeder ifølge krav 2, kendetegnet ved, at det andet fjederben har en bort fra kanalen vendende, udragende modhage. 4. Låsefjeder ifølge krav 1-3, kendeteg net ved, at vinklen mellem fjederbenene er spids. 5. Låsefjeder ifølge krav 3 eller 4, kendetegnet ved, at det andet fjederben er bredere end området hvor fjederbenene mødes. 6. Låsefjeder ifølge krav 1-5, kendeteg net ved, at det første fjederbens længde er af samme størrelsesorden som kanalens tværsnitsdimension.Patent claims: 1. Lock spring for a channel for receiving and fixing pipes or cables with an insertion direction, wherein the spring is resilient as the tube or cable moves in the insertion direction and where the spring cuts into the tube or cable as it moves toward the insertion direction, and where the spring has a spring leg facing the pipe or cable and having a cutting edge, characterized in that the spring leg has at least one abutment area for abutment against the cable for limiting the cutting edge depth. Locking spring according to claim 1, characterized in that the spring has a second spring leg which is contiguous with and forms an angle with said first spring leg, wherein the second spring leg is arranged to be retained in the channel. Locking spring according to claim 2, characterized in that the second spring leg has a protruding protrusion facing away from the channel. Locking spring according to claims 1-3, characterized in that the angle between the spring legs is pointed. Locking spring according to claim 3 or 4, characterized in that the second spring leg is wider than the area where the spring legs meet. Locking spring according to claims 1-5, characterized in that the length of the first spring leg is of the same order of magnitude as the cross-sectional dimension of the channel.
