Abstract
The utility model relates to the LED aging detection technical field and especially relates to a novel conductive brush. The novel conductive brush comprises a copper column, a spring, an outer screwed joint and a copper wire. The spring is divided into a segment with a short equal diameter, a segment with a variable diameter and a segment with a long equal diameter, wherein the segment with the variable diameter is arranged between the segment with the short equal diameter and the segment with the long equal diameter. The outer screwed joint is equipped with an inner connecting end and an outer connecting end. The segment with the short equal diameter is fixedly connected with a connecting end of the copper column. The segment with the long equal diameter is fixedly connected with the inner connecting end. The connecting end of the copper column is also fixedly connected with a wire connecting end of the copper wire. An extension end of the copper wire successively passes through the spring and a cavity of the outer screwed joint. A transverse plane of the extension end is parallel to a transverse plane of the outer connecting end. The novel conductive brush of the utility model is greatly improved in terms of conductivity, is simple in structure, reasonable in arrangement and low in manufacture cost, and helps to prevent contact failure that frequently occurs during a test.
Description
Technical field
The utility model relates to the aging detection technique of LED field, particularly a kind of novel conductive brush.
Background technology
The conduction brush that existing LED aging line conductivity detection is used adopts copper and iron to make usually, due to the poor electric conductivity of iron, thereby affects conduction brush monolithic conductive performance.The parts of this conduction brush are more, and structure is comparatively complicated, make like this manufacture craft of the conduction brush very complex that becomes, and cause the production cost of conduction brush high.In addition, due to the complex structure of conduction brush, it is quite dumb that the connection of all parts just seems, causes often can coming in contact bad phenomenon in test process.Therefore, how to provide a kind of simple in structure, problems such as conduction brush that cost of manufacture is low, electric conductivity is good to become the focus of research in the industry.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and novel conductive brush a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of novel conductive brush described in the utility model comprises copper post, spring, male connection and copper cash, and that described spring is divided into is little isometrical section, reducer and large isometrical section, and reducer is arranged between little isometrical section and large isometrical section; Described male connection is provided with interior link and outer link, and the described little isometrical section link with the copper post is fixedly connected, and described large isometrical section is fixedly connected with interior link; Described link also is fixedly connected with the line link of copper cash, and the external part of described copper cash passes the inner chamber of spring and male connection successively, and the end face of external part is mutually concordant with the end face of outer link.
After adopting said structure, the utility model beneficial effect is: a kind of novel conductive brush described in the utility model, comprise copper post, spring, male connection and copper cash, that described spring is divided into is little isometrical section, reducer and large isometrical section, and reducer is arranged on little isometrical section and large isometrical section; Described male connection is provided with interior link and outer link, and the described little isometrical section link with the copper post is fixedly connected, and described large isometrical section is fixedly connected with interior link; Described link also is fixedly connected with the line link of copper cash, and the external part of described copper cash passes the inner chamber of spring and male connection successively, and the end face of external part is mutually concordant with the end face of outer link.When using the utility model, greatly improved the electric conductivity of conduction brush; Simultaneously of the present utility model simple in structure, arrange rationally, cost of manufacture is low, also can stop in addition often can come in contact bad phenomenon in test process.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of novel conductive brush described in the utility model comprises copper post 1, spring 2, male connection 3 and copper cash 4; Be connected in order can be connected with male connection with copper post 1 in the two ends of spring 2, that described spring 2 is divided into is little isometrical section 21, reducer 22 and large isometrical section 23, and reducer 22 is arranged on little isometrical section 21 and large isometrical section 23.
Described male connection 3 is provided with interior link 31 and outer link 32; Described large isometrical section 23 is fixedly connected with interior link 31, and the connected mode of male connection 3 of the present utility model and spring 2 is to adopt welding.
Described little isometrical section 21 link 11 with copper post 1 is fixedly connected, and the connected mode of copper post 1 of the present utility model and spring 2 is to adopt welding.
Described link 11 also is fixedly connected with the line link 41 of copper cash 4, and the external part 42 of described copper cash 4 passes the inner chamber of spring 2 and male connection 3 successively, and the end face of external part 42 is mutually concordant with the end face of outer link 31.
When using the utility model, greatly improved the electric conductivity of conduction brush; Simultaneously of the present utility model simple in structure, arrange rationally, cost of manufacture is low, also can stop in addition often can come in contact bad phenomenon in test process.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
