(a) Technical Field of the Invention
The present invention is generally related to electrical connectors, and more particular to a connector of enhanced transmission quality, flexible production, and low cost.
(b) Description of the Prior Art
A conventional electrical connector includes at least a metallic case, at least a plastic insulating member inside the metallic case, a number of metallic transmission terminals on the insulating member, and a circuit board connected to the transmission terminals. The metallic case is for engaging a corresponding connector so that the communication link is established between the transmission terminals of the two connectors. However, during signal transmission, there may be radio-frequency (RF) signal leakage from the metallic terminals and the circuit boards, compromising the signal transmission quality.
Therefore the present invention provides a connector of enhanced transmission quality, flexible production, and low cost.
A major objective of the present invention is that the connector is able to reduce interference so as to enhance transmission quality.
Another major objective of the present invention is that the connector is adaptable to various requirements.
Yet another major objective of the present invention is that the connector has a low production cost.
To achieve these objectives, the connector includes a circuit board having a number of electronic components, a transmission assembly joined to the circuit board to a side of the electronic components, a first shielding member on the circuit board shielding the transmission assembly, a second shielding member on the circuit board shielding the electronic components, and a cover on and shielding the first and second shielding members. The connector can be produced by using a common first shielding member joined to a second shielding member adapted to a specific requirement such as dimension, shape, etc. Having separate first and second shielding members to meet different needs contributes to the connector's production flexibility and lowers production and stock costs.
When the connector is used for communications, the set of transmission terminals and the electronic components may produce RF signals. Yet, the transmission assembly is shielded by the first shielding member, the electronic components are shielded by the second shielding member, and the first and second shielding members 31 are further shielded by the cover. Therefore, the RF signals are prevented from leakage, and transmission quality is enhanced.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The first shielding member 31 is disposed on the circuit board 1 and shields the transmission assembly 2. The first shielding member 31 includes at least a second fastening element 311 corresponding to a first fastening element 231 for mutual engagement. The first shielding member 31 further includes at least a plug element 312 corresponding to a socket element 13 for mutual engagement. The second shielding member 32 is disposed on the circuit board adjacent to the first shielding member 31, and shields the electronic components 11. The first and second shielding members 31 and 32 are tightly joined to the circuit board 1 by, for example, soldering. The cover 4 is disposed on and shields the first and second shielding members 31 and 32.
When the connector is connected to a corresponding connector (not shown), the transmission assembly 2 is conducted and signal communication is carried out through the transmission assembly 2 and the circuit board 1. In the communication process, the set of transmission terminals 22 and the electronic components 11 would produce RF signals. However, the transmission assembly 2 is shielded by the first shielding member 31, the electronic components 11 are shielded by the second shielding member 32. In addition, the first and second shielding members 31 and 32 are tightly joined to the circuit board 1, and they are further shielded by the cover 4. Due to the two layers' shielding and the tight joint, the RF signals are prevented from leakage, thereby enhancing transmission quality.
Therefore, compared to the prior art, the present invention provides the following advantages.
Firstly, the first shield member 31, the second shielding member 32, and the cover 4 jointly enhance the transmission quality.
Secondly, having separate first and second shielding members 31 and 32 contributes to the connector's production flexibility and low cost.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
