Functional cable magnetic snap

Abstract

A functional cable magnetic snap can perform combination pairing through an inner fastener and an outer fastener, employs the structures such as the suction of an inner fastener pot magnetic body and an outer fastener magnetizer, the same pot mouth magnetic poles of the same group magnetic snap, the cooperation of the inner fastener outer chamfering and the inner fastening inner chamfering, the multi-bit self-locking of the inner fastener bulge and the outer fastener groove and the outer fastener clearing hole so as to overcome the deficiencies that the current cable magnetic snap is difficult to satisfy the application requirements of big suction volume ratio, the selective suction, the suction slippage preventing, the multi-path adaption and the clearing reuse and realize the functions of the wiring, the wire overlapping, the wire collection, the knot preventing, the slippage preventing, the multiple paths and the clearing reuse of the cable magnetic snap. The functional cable magnetic snap is reliable in structure, simple to operate, easy to dismount, high in adaptability, wide in universality and cost in manufacturing cost, and widely applied to the various types of cables such as charging, power supply or signal cables including a electric vehicle, a mobile device and a handheld terminal.

Description

technical field [0001] The invention relates to a magnetic fastener for cables, in particular to a magnetic cable fastener with multiple functions such as wiring, wire stacking, wire take-up, anti-knotting, anti-slip, multi-diameter, and detachable. Background technique [0002] Cable fasteners have the functions of routing (layout the position and direction of cables), stacking (stacking cables side by side or crossing), winding (wrapping stacked cables), anti-knot (cables only need to be fastened at both ends) After storage, it can prevent knotting when unfolding) and many other uses. Traditional cable fasteners are mostly connecting parts such as binding straps, hooks and loops, buckles, pipe clips, etc. Due to the mechanical fastening connection, although the connection effect is firm Reliable, but fastening and unfastening are not convenient enough to adapt to occasions that need to be repeated frequently.

Problems solved by technology

[0002] Cable fasteners have the functions of routing (layout the position and direction of cables), stacking (stacking cables side by side or crossing), winding (wrapping stacked cables), anti-knot (cables only need to be fastened at both ends) After storage, it can prevent knotting when unfolding) and many other uses. Traditional cable fasteners are mostly connecting parts such as binding straps, hooks and loops, buckles, pipe clips, etc. Due to the mechanical fastening connection, although the connection effect is firm Reliable, but fastening and unfastening are not convenient enough to adapt to occasions that require frequent repetitions

[0003] The technical patents of the magnetic buckle for cables that have been published (such as a removable magnetic wiring snap, easy to store and prevent winding cables), the basic principle is: the permanent magnetic attraction adopts an open magnetic circuit structure, and the cable The connection method adopts a single card slot or a fixed connection; the main disadvantages are: the utilization rate of magnetic energy and the volume ratio of the suction force are low (due to the low magnetic density of the working air gap of the open magnetic circuit), and the magnetic poles must be considered when the magnetic buckle attracts each other when stacking lines (due to The polarities of the magnets must be opposite to each other), and the magnetic buckle is easy to slip when stacking lines (because the shear force between the magnets is much smaller than the tensile force), and it is difficult for a single magnetic buckle to adapt to a variety of cable diameters; so this type The patent is not suitable for applications that require large suction volume ratio, selective suction, anti-slip suction, and multi-wire diameter adaptation, so the promotion and application are limited
