Problems solved by technology

[0002] In the actual use of the traditional common mode filter coil, the current load capacity of the coil is poor. In the case of high current intensity, on the one hand, it is easy to generate a lot of heat, which makes the varnish on the surface of the wire damaged. On the other hand, it is easier to Cause the filter coil to burn out and lose the filtering effect

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] A high-current common-mode filter coil, comprising a circular magnetic core 1, on which two strands of wires 2 are provided, and the two strands of wires 2 are separated by an insulating plate 3, and also includes a base 4, so that The upper surface of the base is provided with a bracket 5 with an arc surface, and the four apex positions of the lower surface of the base 4 are provided with stitches 6, and the two ends of the wire are connected to the connecting line parallel to the axial line of the circular magnetic core. On the two pins of the base, there is also a guide groove 7 on one side of the base parallel to the radial plane of the circular magnetic core.

[0015] The material of the insulating spacer is an epoxy spacer. On the one hand, the epoxy spacer plays an insulating role to prevent short circuits between two st...

Abstract

The invention relates to a current filter device, and in particular relates to a large current common mode filter coil. The large current common mode filter coil comprises a round magnetic core, two strands of wires are wound on the magnetic core and two strands of wires are isolated through an insulation plate; the large current common mode filter coil further comprises a base, the upper surface of the base is provided with a bracket, the surface of which is cambered surface, pins are formed at four peaks of the lower surface of the base, two ends of the wire are connected with two pins being parallel to the axial direction line of the connection line and the round magnetic core, the large current common mode filter coil further comprises a guide slot formed on one side of the base being parallel to the plane of the axial direction of the round magnetic core; the large current common mode filter coil has larger current load capability, uses the filter function for increasing the service life under the large current work state and has practicability.

Description

technical field [0001] The invention relates to a current filtering device, and in particular proposes a large-current common-mode filtering coil. Background technique [0002] In the actual use of the traditional common mode filter coil, the current load capacity of the coil is poor. In the case of high current intensity, on the one hand, it is easy to generate a lot of heat, which makes the varnish on the surface of the wire damaged. On the other hand, it is easier to Cause the filter coil to burn out and lose the filtering effect. Contents of the invention [0003] The purpose of the present invention is to propose a high-current common-mode filter coil, which has a large current load capacity, and can use the filter function in a high-current working state to increase the service life and has practicability. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] A large-current common-mode filter coil, comprising a cir...
