Title: Structure for improving the voltage difference of a connector

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a structure for improving the voltage difference of a connector; in particular, the present invention relates to a structure for improving the voltage difference of a connector that improves the conductivity of a communication connector and an enclosure so as to improve the voltage difference. 
     2. Description of Related Art 
     A communication connector and an enclosure (or named as tuner, can, RF can, iron shell, or lower cover) are conventionally assembled by riveting or soldering. Because the communication connector and the enclosure are independently formed, there is a tiny gap on the contacting surface when the communication connector and the enclosure are assembled. Therefore, the voltage difference generates an increase of electromagnetic interference (EMI). 
     Conventionally, the voltage difference is improved by manually soldering the riveting area. A worker needs to use both hands to respectively hold the tin and the soldering iron, so as to melt the tin to fasten the connector and the enclosure. 
     However, the manual soldering method has the following drawbacks. 
     1. Comparatively more manpower is necessary if the manual soldering method is required. The assembly speed is slow, the cost is high. 
     2. When the soldering operation is performed and the worker needs to rotate the communication connector and the enclosure to change the soldering direction and location, the required soldering time and manpower is further prolonged. 
     3. The fake-solder symptom may occur due to the human factor of carelessness, inferior skill, or the tin being not smoothly pulled. 
     4. Due to worker operation mistake, it is easy to make the high temperature soldering iron contact the surface of the communication connector and the enclosure thereby damage the surface electroplating layer of the communication connector and the enclosure. Therefore, the appearance is of the product is damaged and the quality is lowered due to oxidizing. 
     5. Due to worker operation mistake, it is easy to make the soldering material be stained on the connection pin of the communication connector. Thereby noise may be generated or short-circuit may occur. 
     6. Due to worker operation mistake, it is easy to make soldering flux be carbonized to affect the appearance. Moreover, the carbonized material may flake off to cause other electronic components be short-circuited. 
     SUMMARY OF THE INVENTION 
     One particular aspect of the present invention is to provide a structure for improving the voltage difference of a connector that overcomes the drawbacks of the connector being assembled by the traditional manual soldering, thereby reduces the manpower and the working time to lower the assembly time, and improves the yield rate. 
     The structure for improving the voltage difference of a connector includes a communication connector, an enclosure, and a conducting gasket. The communication connector is assembled with the enclosure. The conducting gasket is located and conducted at the connection area of the communication connector and the enclosure. 
     The present invention has the following characteristics: 
     1. The conductivity and the voltage difference of the communication connector and the enclosure are improved. 
     2. The manufacturing time is reduced to lower the manufacturing cost.

The type of the communication connector  1  is not limited to a specific one. The communication connector  1  can be an F connector manufactured by turning or free-cutting, a PAL connector manufactured by turning, free-cutting, pipe-cutting, or deep-drawing, or other connector. The enclosure  2  is a metallic frame. The enclosure  2  is assembled with communication connector  1 . 
     The conducting element  3  is a conductive metal or material, such as copper, aluminum, tin, iron, tin-strip, conducting gasket, or conductive glue, etc. In this embodiment, the conductive element  3  is a non-sticky conductive gasket  31 . The conductive gasket  31  is a conductive metal or material and is non-sticky. The shape of the raw material can be flake-shaped, strip-shaped, board-shaped, roll-shaped, etc. The raw material is formed into a conductive gasket  31  by using a forming tool (traditional, airing, or pressuring), a slide forming or a rolling-knife punching tool, and a forming mold. 
     The conducting gasket  31  is located and conducted at the connection area of the communication connector  1  and the enclosure  2 . Furthermore, the conducting gasket  31  can be installed at the outer side of the enclosure  2  (as shown in  FIGS. 1 and 2 ), or the inner side of the enclosure  2  (as shown in  FIGS. 3 and 4 ) depending on the requirements and the efficiency.
