Description

Technical Field

[0001] The present application relates to an iron core for a contactor and a contactor comprising the iron core. Background Art

[0002] When a contactor is used in a salt spray environment, the contactor's iron core (including the moving and stationary cores) is subject to corrosion from the salt spray. To reduce this corrosion, existing technologies employ rust-proof coatings on the core surfaces. However, this increases the air gap between the moving and stationary cores when they are closed, reducing the holding force. Existing technologies also employ oiling the core surfaces, which reduces costs. However, this still increases the air gap between the moving and stationary cores when they are closed, resulting in reduced holding force.

[0003] Therefore, there is a need for an iron core of a contactor that can reduce the corrosion of the iron core in a salt spray environment while not increasing the air gap between the moving iron core and the static iron core. Summary of the Invention

[0004] In order to solve the above problems, the present application provides an iron core for a contactor, including an iron core body, wherein the iron core body has a plurality of silicon steel sheets stacked and fixed together, wherein the iron core body also has a metal rod, which passes through and is fixed to at least some of the plurality of steel sheets, and the material of the metal rod is selected from one or more of aluminum, aluminum alloy, magnesium, magnesium alloy, zinc, and zinc alloy.

[0005] Advantageously, the metal rod penetrates through and is fixed to all silicon steel sheets in the plurality of silicon steel sheets.

[0006] Advantageously, the core body further comprises steel rivets for penetrating the plurality of silicon steel sheets to fix and connect the plurality of silicon steel sheets.

[0007] Advantageously, the iron core is a moving iron core having a first portion extending along a first direction and a second portion extending along a second direction perpendicular to the first direction, and the moving iron core is movable along the second direction.

[0008] Advantageously, the metal rod is arranged in the second part.

[0009] Advantageously, the iron core is a static iron core having a first portion extending along a first direction and two second portions extending along a second direction perpendicular to the first direction at both ends of the first portion.

[0010] Advantageously, the static iron core further comprises extending portions extending from ends of the two second portions away from the first portion toward each other along the first direction, such that a gap is formed between the two extending portions.

[0011] Advantageously, a metal rod is provided at the junction of the first part and the second part.

[0012] The present application also provides a contactor, which includes the iron core as described above. BRIEF DESCRIPTION OF THE DRAWINGS

The words "first", "second" and similar terms used in the patent application specification and claims of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. When the number of components is not specified, the number of components may be one or more; similarly, words such as "one", "the", and "said" do not necessarily indicate a quantity limitation. Words such as "include" or "comprising" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.

When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0018] Figure 1 A perspective view of a contactor according to the present invention is shown, which can be used in a salt spray environment. The contactor includes a moving iron core 11 and a stationary iron core 12. The moving iron core can move between a closed position and a separated position. In the closed position, the moving iron core contacts the stationary iron core, and in the separated position, the moving iron core is separated from the stationary iron core.

[0019] The moving iron core 11 and the stationary iron core 12 can be collectively referred to as the "iron core." In this case, the moving iron core 11 and the stationary iron core 12 each include an iron core body, which comprises a plurality of silicon steel sheets 131 stacked together and fixedly connected by steel rivets 132. The steel rivets 132 are positioned in appropriate locations and can be present in an appropriate number. The iron core also includes a metal rod 133, the material of which is selected from one or more of aluminum, an aluminum alloy, magnesium, a magnesium alloy, zinc, and a zinc alloy.

[0020] The metal rod 133 penetrates and is fixed to all the silicon steel sheets in the plurality of silicon steel sheets. The core body further comprises steel rivets for penetrating the plurality of silicon steel sheets to fix and connect the plurality of silicon steel sheets.

[0021] The movable core 11 has a first portion 111 extending in a first direction and a second portion 112 extending in a second direction perpendicular to the first direction. The movable core 111 is movable toward and away from the stationary core along the second direction. A metal rod 133 is disposed in the second portion 112 .

[0022] The static iron core 12 includes a first portion 121 extending along a first direction and two second portions 122 extending along a second direction perpendicular to the first direction at both ends of the first portion.

[0023] The static core further includes extensions 123 extending from ends of the two second portions away from the first portion toward each other along a first direction, forming a gap between the two extensions. The second portion of the moving core can extend through the gap, so that the first portion of the moving core faces the extensions.

[0024] The metal rod 133 is arranged at the connection between the first part and the second part of the static iron core. However, the position of the metal rod 133 is not limited to this, and a suitable position can be selected as needed. Similarly, a suitable number of metal rods can also be selected.

[0025] The metal rod 133 of the present application forms a sacrificial anode when the contactor is used in a salt spray environment. Chloride ions in the salt spray preferentially react with the metal rod, releasing electrons. These electrons are transferred to the silicon steel sheet through the salt spray solution, providing cathodic protection and reducing corrosion. Furthermore, the moving and stationary iron cores do not require electroplating coatings or anti-rust oil, which does not reduce holding power.

[0026] Although the present invention has been described in the specification and illustrated in the drawings with reference to various embodiments, those skilled in the art will understand that the above embodiments are merely preferred implementation methods, and certain technical features in the embodiments may not be necessary for solving specific technical problems, so that these technical features may be absent or omitted without affecting the solution of the technical problems or the formation of technical solutions; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
