Description

Electric reactor

Technical Field

The utility model belongs to the field of low-voltage electric appliances, and particularly relates to a reactor.

Background

Reactors, also called inductors, are electrical conductors that, when energized, generate a magnetic field in a certain spatial area occupied by a conductor, so that all electrical conductors capable of carrying current are inductive in the general sense. However, the inductance of the electrified long straight conductor is small, and the generated magnetic field is not strong, so that the actual reactor is in a mode that a lead is wound into a solenoid, and is called as an air-core reactor; in order to make this solenoid have a larger inductance, a core is inserted into the solenoid, which is called a core reactor.

Most of the existing magnetic yoke is connected by screws subjected to special treatment, the whole process is troublesome, and the production cost is high.

In order to overcome the defects of the background art, the utility model provides the reactor, and mainly solves the problems that the magnetic yoke of the existing reactor is mostly connected by specially processed screws, the whole process is troublesome, and the production cost is high.

The technical scheme adopted by the utility model is as follows:

the reactor comprises a magnetic yoke and a coil, wherein the magnetic yoke comprises a cross beam, a mounting hole is formed in the cross beam, a fastener is connected to the mounting hole, the reactor also comprises a sheath made of a magnetism isolating material, and at least part of the sheath is arranged on the outer wall of the fastener and between the inner walls of the mounting hole.

The fastener is a screw rod and a nut, and two ends of the screw rod extend out of the mounting hole and are connected with the nut.

The sheath is made of plastic.

The outer side of the magnetic yoke is provided with a pressing sheet, the sheath comprises a bottom sheet and a cylinder, the nut directly or indirectly supports against the bottom sheet on the pressing sheet, and the cylinder extends into the mounting hole.

And a gasket is arranged between the nut and the bottom sheet.

Be equipped with on the yoke and be used for the winding the skeleton of coil, the skeleton is including first support body and the second support body that can dismantle the connection.

The first frame body is provided with a convex block, and the second frame body is provided with a groove clamped with the convex block.

The second support body includes the horizontal pole, the recess is followed horizontal pole length direction is provided with a plurality ofly.

The utility model has the beneficial effects that: the utility model provides a reactor, which realizes the magnetic isolation effect through a magnetic isolation piece, does not need a special fastener, reduces the cost and reduces the working procedures.

Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the reactor comprises a magnetic yoke 1 and a coil 2, wherein the magnetic yoke comprises a cross beam 3, a mounting hole 31 is formed in the cross beam, a fastening piece 4 is connected to the mounting hole, the reactor further comprises a sheath 41 made of a magnetism isolating material, and at least part of the sheath is arranged between the outer wall of the fastening piece and the inner wall of the mounting hole. When the reactor is installed, the sheath is sleeved outside the fastener and then is installed in the installation hole, the fastener can be a screw rod and a nut, and the two ends of the screw rod extend out and then are fixed through the nut.

In this embodiment, as shown in the figure, the fastening member is a screw 401 and a nut 402, and two ends of the screw extend out of the mounting hole to be connected with the nut. Through the connected mode of screw rod and nut, the dismouting is more convenient.

In this embodiment, the sheath is made of plastic, as shown. The cost is low.

In this embodiment, as shown in the figure, a pressing sheet 11 is disposed outside the magnetic yoke, the sheath includes a bottom sheet 411 and a cylinder 412, the nut directly or indirectly presses the bottom sheet against the pressing sheet, and the cylinder extends into the mounting hole. The sheath is fixed by pressing the bottom sheet, and the installation is simpler.

In this embodiment, as shown in the figure, a gasket 12 is further disposed between the nut and the bottom plate. The stability of installation is further increased, and the gasket can adopt the metal material also can adopt the rubber material.

In this embodiment, as shown in the figure, a skeleton for winding the coil is disposed on the magnetic yoke, and the skeleton includes a first frame body 51 and a second frame body 52 that are detachably connected.

In this embodiment, as shown in the figure, a protrusion 511 is disposed on the first frame body, and a groove 521 is disposed on the second frame body and clamped with the protrusion. The total length of the first and second housings may be adjusted to accommodate different coils.

In this embodiment, as shown in the figure, the second frame body includes a cross bar 520, and the groove is provided in plurality along the length direction of the cross bar.
