Embodiment
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
Embodiment one
A kind of magnetic ring component, including magnetic ring shell 1 and magnet ring 2.As shown in Figure 2-5, magnetic ring shell 1 include circular shell 11, Magnet ring groove 12, cable passage 13, fastener 14.Circular shell 11 is assembled by upper shell 11a and lower house 11b.Upper shell 11a and lower house 11b can use injection moulding integrated molding, realize batch production.Magnet ring groove 12 is located in circular shell 11 to be same In annular groove, for installing magnet ring 2.Cable passage 13 in the shape of a spiral, spacing uniformly set around the magnet ring groove 12 of ring-type, Form the passage for installing cable 3.The cable entries 131 and cable that cable passage 13 includes located at the surface of circular shell 11 go out Mouth 132.Wherein cable entries 131 and cable exits 132 can be arranged on upper shell 11a, can also be arranged at lower casing On body 11b, or respectively on upper shell 11a and lower house 11b.Be additionally provided with cable entries and cable exits for pair The cable clamp that cable in passage is fixed.Specifically, cable passage 13 includes being located at upper shell 11a Part I and set In lower house 11b Part II.Upper shell 11a is provided with the first keeper 111, and lower house 11b is provided with and the first keeper Second keeper 112 of 111 matchings.First keeper 111 and the second keeper 112 coordinate so that upper shell 11a and lower house When 11b is fitted together, the Part I and Part II of cable passage 13 are stitched together, and form a complete cable and lead to Road.For example, the first keeper 111 can be the positioning convex being arranged on upper shell, the second keeper 112 can be to be arranged on Detent on lower house, when assembling circular shell 11, upper shell 11a and lower house 11b is aligned, and causes upper shell Positioning convex is snapped onto in the detent of lower house, and at this moment, Part I, the Part II of cable passage 13 mutually splice shape Into cable passage 13.
Fastener 14 is arranged in magnet ring groove 12, to enable magnet ring groove 12 to match with various sizes of annular magnet ring 2. The fastener slot 121 for being used for installing fastener 14 is provided with magnet ring groove 12.Fastener 14 includes being used for and fastener slot 121 The installation portion 141 of Matching installation and the elastic contact part 142 for fastening positioning to magnet ring.Fastener slot 121 is along thickness side To the inwall for being arranged on magnet ring groove 12.Installation portion 141 is arranged on one end towards fastener slot 121 of fastener 14;Contact Portion 142 is arranged on one end towards magnet ring 2 of fastener 14 so that when fastener 14 is arranged in magnet ring groove 12, contact site 142 Leant with magnet ring 2.Contact site 142 is provided with imitation profile with the part that magnet ring 2 leans;The magnetic that the shape of imitation profile is in contact with it The shape of the outer surface of ring 2 matches so that contact site 142 fits with magnet ring.For example, imitation profile can be with outside magnet ring 2 The concave surface of surface fitting.
The assembling process of magnetic ring component of the present invention is:
Magnet ring is put into the magnet ring groove of lower house, selects to fasten to being placed on magnet ring in suitable fastener insertion magnet ring groove It is spacing.By upper case cover on lower house, ring is formed by the first keeper and the second keeper upper shell and lower house Shape housing, and it is spliced to form cable passage.Then, upper-lower casing is fixed together by screw, completes assembling.By line Cable stretches into from the cable entries positioned at circular shell surface, promotes cable through cable passage and is spread out of through cable exits so that Cable is located in cable passage.Finally, cable is fixed by cable clamp at cable entries and cable exits.
Now, cable is realized uniformly around being located on magnet ring, and is now located in cable passage, is greatly improved magnetic Ring performance.Magnetic ring shell can be pointed to magnet ring and cable therein and be protected, and extend its life-span.Can be with by magnetic ring shell The spacing and the number of turn of the coil of winding on magnet ring are standardized, filter function is more stable.Magnet ring groove is tight by what is be disposed therein Firmware be opposite to magnet ring therein fasten it is spacing so that magnetic ring shell can match the magnet ring of different dimensional standards.In addition, The shell of the cable passage with spacing can be selected as needed for the magnet ring, corresponding to around being located on the magnet ring not Same coil turn, assembling are more convenient.
Although being described in conjunction with the accompanying embodiments of the present invention, those of ordinary skill in the art can be in appended power Profit makes various deformations or amendments in the range of requiring.
