The present invention relates to the field of electronic devices, in particular to a high frequency electronic connector that increases the contact area between male and female terminals to improve the integrity and continuity of the transmission of high frequency electronic signals, so as to ensure the stability of the signal quality.
To cope with the thin design of mobile devices such as smart phones, tablet PCs, and notebook computers, various related electronic components are developed with thin and light features and high performance. In recent years, electronic products have increasingly higher demand on the application of high speed signals, and the number of connection terminals required by mobile devices and other video and recreational electronic products become increasingly larger. Due to the limitation of the miniaturization of the electronic products, the electromagnetic interference (EMI) effect become a serious issue, and high frequency circuit design and electromagnetic wave protection become very important. Since an electronic signal is transmitted through the current flowing between two terminals, and the flow of current in the terminals produce a magnetic field at the outer side of the terminals (according to the Oersted's magnetic effect of electric current), so that when the total volume of a connector is reduced, and the distance between the terminals becomes very small, electromagnetic interference (EMI) will be produced, and the accuracy and transmission efficiency of signals will be affected.
To overcome the aforementioned problem, the structure of some conventional connectors is changed to improve the quality of high frequency signal transmission, but this solution creates another problem, since the whole structure of the connector becomes more complicated, and the complicated structure is disadvantageous for the production process, particularly when the connection terminals are very small. The components are damaged very often during the assembling process, and the production is increased. In view of the drawbacks of the prior art, it is an important subject for the present invention to improve the stability of high frequency signal transmission and reduce the production failure rate without complicating the design of the connector.
Therefore, it is a primary objective of the present invention to overcome the drawbacks of the prior art by providing a high frequency electronic connector, wherein the contact area of male and female terminals in the connector is increased to achieve a good high frequency property and reduce the failure rate of engagement.
To achieve the aforementioned and other objectives, the present invention provides a high frequency electronic connector, comprising a first connector and a second connector, and the first connector includes a first body and at least one first terminal, and the first body has the first terminal built therein, and the second connector includes a second body and at least one second terminal, and the second body has the second terminal built therein and provided for plugging the first body, characterized in that the first terminal has a front end surface which is substantially a slope or a curved surface, and the second terminal has a front end surface which is at least one slope or at least one curved surface for increasing the contact area between the first terminal and the second terminal, and improving the stability of a high frequency signal transmission.
Wherein, the high frequency electronic connector is inserted and coupled into a motherboard having a plurality of contacts, and the motherboard is electrically coupled to at least one external electronic device. The electronic device is inserted and coupled to the motherboard through the contacts and electrically coupled to the high frequency electronic connector, or the electronic device is inserted and coupled to the contacts through at least one external cable, and the contacts are electrically coupled to the high frequency electronic connector. At least one of the first and second terminals is elastic, so that when the first connector is inserted and coupled to the second connector, at least one of the first and second terminals elastically absorbs the stress produced at the moment of engagement to improve the overall reliability, and the second body is fixedly or elastically contacted with the first body to achieve an insertion and engagement effect. The front end surfaces of the first terminal and the second terminal area are oblique contact surfaces having an angle of 18-45 degrees with respect to a horizontal plane, and the first terminal and the second terminal are disposed opposite to each other. Alternately, the front end surface of the first terminal is substantially in a convex arc shape, and the front end surface of the second terminal is substantially in a concave arc shape and corresponsive to the front end surface of the first terminal. In an embodiment, the front end surface of the first terminal is substantially in a convex arc shape, and the front end of the second terminal has a plurality of slopes in different shape and disposed continuously around the front end of the second terminal, and two oblique slopes are arranged opposite to each other to form a plurality of cones and a plurality of grooves. Alternately, the front end surface of the first terminal is in a convex curved shape, and the front end of the second terminal has a plurality of convex curved surface disposed continuously around the front end surface of the second terminal.
In addition, the first body and the second body are made of a polymer or an electrically conductive material for enhancing the capability of resisting electromagnetic interference. The second body has at least one hole filled with polymer or air.
In summation, the present invention simply increases the contact area between the front end surface of the first terminal and the front end surface of the second terminal while using the elasticity of the first terminal to reduce the stress produced at the moment of engaging the first connector and the first connector, so that the high frequency electronic connector has a good high frequency produce and reduce the failure rate of engagement, and the high frequency connector of the invention also allows the connector to be plugged and unplugged for many times and improve the overall reliability and quality of the high frequency signal transmission.

The front end surface of the first terminal 201 is a curved surface, and the front end surface of the second terminal 211 is at least one curved surface. For example, if the front end surface of the first terminal 201 is in a convex arc shape, the front end of the second terminal 211 has a plurality of slopes in different shapes disposed continuously around the front end of the second terminal 211, and two oblique slopes in different directions have a plurality of cones and a plurality of grooves, so that when the two terminals are engaged, the convex arc shape of the first terminal 201 may use the sharp cones to scrape a surface oxide layer while increasing the contact area between the first terminal 201 and the second terminal 211, improve the stability of high frequency signal transmission, and achieve a good high frequency property.
