AI Technical Summary
The existing wire reel conductive contact system has a large space size due to the plane arrangement of the annular contact sheet, which affects the miniaturization and portability of the product.
By providing annular contact sheets on different planes with upper and lower height drops on the outer hub of the reel, the contact sheets are placed using step portions and groove structures to reduce space occupation in the plane direction.
While ensuring the safe distance between the annular contact sheets, the space size of the conductive system is reduced, which is conducive to the miniaturization and portability of the wire reel product.

Abstract
Description
Technical Field
[0001] The utility model relates to a wire reel conductive contact system for saving space, belonging to the technical field of wire reel products. Background Art
[0002] A wire reel is used to wind relatively long cables. The cables are wound on the wire reel and pulled out when in use, and the corresponding length is pulled out according to the usage needs. It can save space and the cables will not be messy. The wire reel is also used in combination with electrical appliances. When the external power supply is far away from the electrical appliance, a wire reel is needed to supply power to the electrical appliance. In order to achieve power supply, one end of the cable needs to be connected to the conductive system of the wire reel. A conductive contact system is provided on the wire reel as a part of the conductive system. The conductive contact system can be two annular contact pieces. The traditional annular contact pieces are generally in the same plane. In order to ensure the safety distance between the two annular contact pieces, the spatial size of the entire conductive system is made very large, resulting in a relatively large volume of the wire reel product, which is not conducive to the miniaturization and portability of the wire reel product. Summary of the Utility Model
[0003] The main technical problem to be solved by the utility model is to provide a wire reel conductive contact system for saving space, which can ensure the safety distance between two annular contact pieces while keeping the spatial size of the entire conductive system not very large, and is conducive to the miniaturization and portability of the wire reel product.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: to provide a wire reel conductive contact system for saving space, which includes an outer hub of the wire reel. The outer hub of the wire reel includes a first cylindrical section. A second cylindrical section is provided at the lower end of the first cylindrical section. A third cylindrical section is provided at the lower end of the second cylindrical section. A first annular step portion is formed between the bottom of the second cylindrical section and the top of the third cylindrical section. A first annular contact piece is provided on the first annular step portion. A fourth cylindrical section is provided at the lower end of the third cylindrical section. A second annular step portion is formed between the bottom of the third cylindrical section and the top of the fourth cylindrical section. A second annular contact piece is provided on the second annular step portion.
[0005] Preferably, a first annular groove is provided on the first annular step portion, and the first annular contact piece is located in the first annular groove.
[0006] Preferably, a second annular groove is provided on the second annular step portion, and the second annular contact piece is located in the second annular groove.
[0007] Preferably, the first cylindrical section, the second cylindrical section, the third cylindrical section and the fourth cylindrical section are coaxial.
[0008] The beneficial effects of the present utility model are as follows: The space-saving wire rewinder conductive contact system of the present utility model changes the original arrangement of two annular contact pieces in one plane and places the two annular contact pieces in different planes with a vertical height difference. While ensuring the safe distance between the two annular contact pieces, the overall spatial dimension of the conductive system is not very large, which is conducive to the miniaturization and portability of the wire rewinder product.
