Abstract
The utility model relates to a spiral spring contact used on a high-voltage device for carrying out conductive contact in the electric power industry which is characterized in that the contact is a spring ring which is formed by the end-to-end connection of spiral springs; the proportion of the height H of the spring ring to the height h of an embedded notch is as follows: H is more than h, but equal to or less than 2h; the contact is the spring ring manufactured by the material of glucinfum bronze with high conductive performance; as the contact is designed into a spiral spring shape, the spiral spring contact used on a high-voltage device for carrying out conductive contact in the electric power industry an maintain excellent contact with a contact seat after deformation; as the glucinfum bronze with high conductive performance and elasticity is adopted as the material to manufacture the spring, the conductive performance is ensured; as the structure is simple, the operation is convenient and the contact performance is reliable, the spiral spring contact used on a high-voltage device for carrying out conductive contact in the electric power industry which is characterized in that the contact is a spring ring has very large practical and popularization values.
Description
Technical field
The utility model relates to power industry and is used for a kind of contact device on the high-tension apparatus, specifically a kind of helical spring contact that is used for conducting electricity on the high-voltage electrical equipment contact.
Background technology
Relevant by retrieval patent documentation does not retrieve the helical spring contact that be used for High-Voltage Electrical Appliances on be used as conduction usefulness identical with the utility model structure at present as yet.Switch contact as conduction on the existing High-Voltage Electrical Appliances is generally watchband contact, Mume flower contact.The watchband contact is because the less and notch shape complexity of its adjustable range, required precision height, concerning machine work and assembling, be difficult to reach requirement, particularly access times many after usually cause tired jail, contact, thereby cause fault often to take place, influence product quality.Mume flower contact is because its adjustable range is smaller, complex structure, and by a plurality of parts form, volume is big, cost is high, particularly use on the GIS combined electrical apparatus and cause danger easily, had a strong impact on reliability of products, so be necessary existing structure is improved, to improve reliability of products.
Summary of the invention
The purpose of this utility model is to provide that a kind of to have elastic range big, can keep elasticity stable, and machine work and assembling can be used for a kind of helical spring contact on the electrical equipment such as isolating switch, circuit breaker easily.
In order to realize the purpose of this utility model, take following technical scheme to implement:
The helical spring contact is characterized in that: described contact is the spring coil of spiral spring through joining end to end and forming.Described spring coil height H with the ratio of the notch height h that embeds mutually is: 2h 〉=H＞h.Described contact is that the beryllium-bronze with high conduction performance is the spring coil that material is made.
When needs use, the utility model is sleeved in the groove of conducting rod conductor, the external diameter of helical spring contact is greater than the internal diameter of contact base at this moment, after the conductor drive helical spring contact of conducting rod enters contact base, under the effect of pressure, the spring external diameter is corresponding to be dwindled and bullet rises in the endoporus of contact base, keeps forming the excellent contact state with contact base.
The utility model has the advantages that:, thereby the utility model can be kept and the contact base excellent contact after distortion because contact design becomes coil spring shape; Because adopting high conduction and rubber-like beryllium-bronze is that material is made spring, thereby has guaranteed electric conductivity; Because simple in structure, easy to operate, contact performance is reliable, so very big practical and popularizing value is arranged.
Description of drawings
Below with reference to accompanying drawing the utility model is further described:
Accompanying drawing 1 is the structural representation of the utility model helical spring contact;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to cutaway view;
Accompanying drawing 3 is working state structure schematic diagrames of helical spring contact.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, helical spring of the present utility model contact 1, the beryllium-bronze that employing has high conduction performance is that material is made spiral spring, and through the formation spiral spring circle that joins end to end, described spring coil height H with the ratio of the notch height h that embeds mutually is: 2h 〉=H＞h, present embodiment H is: H=1.5h.Helical spring of the present utility model contact 1 is sleeved in the groove of conducting rod conductor 2, after the conductor 2 drive helical spring contacts 1 of conducting rod enter contact base 3, under the effect of pressure, the external diameter of helical spring contact 1 is corresponding to be dwindled and bullet rises in the endoporus of contact base 3, keeps forming the excellent contact states with contact base 3.
Claims (3)
1. helical spring contact is characterized in that: described contact is the spring coil of spiral spring through joining end to end and forming.
2. according to claims 1 described helical spring contact, it is characterized in that: described spring coil height H with the ratio of the notch height h that embeds mutually is: 2h 〉=H＞h.
