Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Examples
Example 1
The embodiment provides a magnetism spare fixing device, including the body, be fixed in the U type magnetism spare fixed part of body, be located the body both sides and be used for inserting U type magnetism spare 4 logical groove 8 and be fixed in the electrically conductive copper bar fixed part of body, magnetism spare fixing device 5's material can select plastics.
Specifically, the method comprises the following steps:
u type magnetism spare fixed part includes a plurality of U type magnetism spare jack catchs 7, and a plurality of U type magnetism spare jack catchs 7 evenly set up relatively, as shown in fig. 3, can be for two U type magnetism spare jack catchs 7 of relative setting, U type magnetism spare jack catch 7 is equipped with fillet direction inclined plane, U type magnetism spare jack catch 7 and U type magnetism 4 interference fit, and U type magnetism spare jack catch 7's the back is equipped with the strengthening rib.
Conductive copper bar fixed part is including the web solid fixed part portion of the U type department of bending web 10 of fixed conductive copper bar 6, and the web fixed part includes a plurality of conductive copper bar jack catchs 12, and conductive copper bar jack catch 12 also can be for relative even setting, be equipped with fillet direction inclined plane, be equipped with the strengthening rib with the U type department of bending web 10 interference fit and the back of conductive copper bar 6.
The conductive copper bar fixing part can also comprise a wing plate fixing part 9 for fixing a wing plate at the U-shaped bending part of the conductive copper bar 6, and the wing plate fixing part 9 is formed by extending the body.
