BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention generally relates to an electronic connector for use with data processing facility, and more particularly to an electronic connector that provides convenience in both manufacturing and use thereof by allowing for insertion into a connector female portion, in a bidirectional manner, in both normal direction and reverse direction, while setting terminal pins on the same side of a circuit substrate and soldered in a single row.
(b) Description of the Prior Art
The prosperity of the electronic industry brings the demand of connectors for almost all the electronic products. Universal serial bus (USB) that is most commonly used in the market is an association defined standard interface specification for connectors. Such a specification is the most commonly used one and there are various improvements derived for the connectors, among which the most simple and easiest one is bidirectional insertability of connectors. Since mating between a male portion and a female portion of a connector is generally allowed in a fixed direction, due to various factors, such as inadvertency, during the operation by a user, it is often that insertion in an opposite direction occurs. Such an unexpected situation may cause a consequence of damaging the terminal pins of the connector, or even electrical shorting that destructs electronic facility. Thus, the bidirectional insertion connectors proposed by the manufacturers are indeed an improvement of convenience and usefulness.
However, such an improvement is limited to the specification of USB2.0. With the quick development of the modem technology, progress is made everyday. Connectors, such as USB2.0, USB3.0, Type-A, and Type-B, must advance with time in respect of for example increase of transmission speed and upgrading of hardware specification. However, such a bidirectional insertion connector is only applicable to USB2.0 and is not suitable for more advanced connectors.
Thus, it is a goal that the present inventor and those involved in the business are eager to achieve for overcoming the problems and drawbacks of the bidirectional insertion connector.
SUMMARY OF THE INVENTION
In view of the above-discussed drawbacks, the present invention aims to provide an electronic connector by expanding the technology of bidirectional insertion to cover various types of USB connector and integrating those connectors as a unitary device with the manufacturing process being achieved with the known techniques so as to enhance the convenience of the using side and the manufacturing side.
The primary object of the present invention is to achieve insertion into a connector female portion in both normal direction and reverse direction by means of two rows of spring contacts of a transmission conductor group and to maintain the easiness of soldering operations by means of an arrangement of a single row of a transmission conductor pin group, and to shield the transmission conductor group with an inclined cover section and two shielding enclosures so as to reduce the occurrence of electromagnetic interference and radio frequency interference.
To achieve the above object, the present invention provides a structure that comprises: a transmission conductor group that comprises two rows of spring contacts to allow for insertion into a connector female portion in both normal direction and reverse direction, a transmission conductor pin group that is arranged at a rear side of the transmission conductor group in an arrangement of a single row, the transmission conductor group being soldered to a circuit substrate, and a shielding housing for accommodating the transmission conductor group and an inclined cover section extending from the shielding housing to shield the transmission conductor pin group, whereby during the manufacture of the present invention in the manufacturing side, the two rows of the transmission conductor group are separated by a first shielding enclosure to be respectively located on upper and lower sides to allow for easy assembly and reduction of mutual interference and the transmission conductor pin group at the rear side of the two-rowed transmission conductor group is arranged, collectively, at one side of the circuit substrate to further ease the operations in the manufacturing side, and finally, the inclined cover section is used to shield the transmission conductor pin group to achieve further isolation of noise inside and outside the second shielding enclosure, so that the user may have the convenience of insertion in two directions with absolutely no concern about direction of insertion and the present invention provides a protection measure for noise isolation, allowing for use without unnecessary concern.
With the above-described technique, the problems of the conventional bidirectional insertion connectors that the range of application of the connector is not good and the manufacturing process is difficult can be overcome to achieve the above-discussed advantages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
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.
Referring to FIGS. 1, 2, and 3, which are respectively a perspective view of a preferred embodiment of the present invention, a perspective view showing two rows of pins of the preferred embodiment of the present invention, and another perspective view showing two rows of pins of the preferred embodiment of the present invention, the drawings clearly show an electronic connector 1 in accordance with the present invention comprises:

a circuit substrate 4, which is electrically connected to the transmission conductor pin group 12;
a shielding housing 3, which receives the transmission conductor group 2 therein, the shielding housing 3 comprising an integrally-formed first shielding enclosure 32 that surrounds the transmission conductor group 2 and an integrally-formed second shielding enclosure 33 that houses the transmission conductor group 2; and
