This application claims the priority of Taiwanese Patent Application No. 111133049, entitled “ELECTRICAL CONNECTOR AND BASE”, filed on Aug. 31, 2022, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to an electrical connector and its base, and more particularly, to an electrical connector and its base that can realize non-directional docking.
As the market demand for cables is getting higher and higher, the specifications of the matching connectors are more stringent, and more and more attention is paid to the connector components of different interfaces. The structure of the contact interface determines the electrical and mechanical properties of the connector, such as resistance value, mating force and durability. However, usually in a connector assembly, the connector and its base are connected in a specific direction, and the user can only assemble according to the set direction.
If the connector is incorrectly assembled, the pins of the connector will be damaged, and the electronic equipment will be reimbursed in severe cases. Therefore, in order to avoid the occurrence of unexpected situations, which results in the malfunction of the connector assembly and in order to allow designers to design the circuit layout without limitations, a connector assembly where the connector and its base has no specific assembly direction is needed.
One objective of an embodiment of the present disclosure is to provide an electrical connector and its base that have no specific assembly direction, to solve the above-mentioned issue.
According to an embodiment of the present disclosure, an electrical connector is disclosed. The electrical connector comprises: an upper insulating shell, provided with at least one socket; a lower insulating shell, arranged under the upper insulating shell and connected with the upper insulating shell; a first-polarity conductive terminal, provided with a first elastic piece portion and a first connecting portion, wherein the first elastic piece portion is correspondingly arranged with a socket of the upper insulating shell; a second-polarity conductive terminal, provided with a second elastic piece portion and a second connecting portion, wherein the second elastic piece portion is correspondingly arranged with a socket of the upper insulating shell; a third-polarity conductive terminal, provided with a third elastic piece portion and a third connecting portion, wherein the third elastic piece portion is correspondingly arranged with an insertion hole of the upper insulating shell; a central conductor, coupled to the first connecting portion of the first polarity conductive terminal, having a central fixing portion and a central contact portion, wherein the central fixing portion allows the central conductor to be fixed to the lower insulating shell; a first outer conductor, coupled to the third connecting portion of the third-polarity conductive terminal, having a first outer fixing portion and a first outer contact portion, wherein the first outer fixing portion allows the first outer conductor to be fixed to the lower insulating shell; and a second outer conductor, coupled to the second connecting portion of the second-polarity conductive terminal, having a second outer fixing portion and a second outer contact portion, wherein the second outer fixing portion allows the second outer conductor to be fixed to the lower insulating shell; wherein the first outer contact portion of the first outer conductor, the central contact portion of the central conductor and the second outer contact portion of the second outer conductor are sequentially arranged outside the lower insulating shell.
According to an embodiment of the present disclosure, a base is disclosed. The base comprises: a first insulating shell, provided with at least one socket; a second insulating shell, arranged under the first insulating shell, and connected with the first insulating shell; a central terminal, provided with a central docking portion and a central connecting portion, wherein the central docking portion is disposed correspondingly to a socket of the first insulating shell, and the central connecting portion allows the central terminal to be fixed between the first insulating shell and the second insulating shell; a first outer ring terminal, provided with a first outer ring docking portion and a first outer ring connecting portion, wherein the first outer ring docking portion is arranged correspondingly to a socket of the first insulating shell, and the first outer ring connecting portion allows the first outer ring terminal to be fixed between the first insulating shell and the second insulating shell; a first inner ring terminal, provided with a first inner ring docking portion and a first inner ring connecting portion, wherein the first inner ring docking portion is arranged correspondingly to a socket of the first insulating shell, and the first inner ring connecting portion allows the first inner ring terminal to be fixed between the first insulating shell and the second insulating shell; a second outer ring terminal, provided with a second outer ring docking portion and a second outer ring connecting portion, wherein the second outer ring docking portion is arranged correspondingly to a socket of the first insulating shell, and the second outer ring connecting portion allows the second outer ring terminal to be fixed between the first insulating shell and the second insulating shell; and a second inner ring terminal, provided with a second inner ring docking portion and a second inner ring connecting portion, wherein the second inner ring docking portion is arranged correspondingly to a socket of the first insulating shell, and the second inner ring connecting portion allows the second inner ring terminal to be fixed between the first insulating shell and the second insulating shell; wherein the first outer ring docking portion of the first outer ring terminal and the first inner ring docking portion of the first inner ring terminal are disposed correspondingly to a same socket, and the second outer ring docking portion of the second outer ring terminal and the second inner ring docking portion of the second inner ring terminal are disposed correspondingly to a same socket.
To sum up, in the electrical connector and its base provided by the present disclosure, the structural design of the contact interface does not have a specific assembly direction, so as to realize non-directional docking and save the cost of the foolproof structure. Furthermore, the designer could have a better flexibility in the circuit layout. In addition, its structural design makes the connector components have polarities, and the number of components conducting between the electrical connector and its base is also different depending on their docking angle. This raises its applicability.

In addition, the socket 111 can also be a Universal Serial Bus (USB) socket 111, which is used to supply power to electronic devices having the USB2.0, USB 2.0 Standard A, USB 2.0 Type C, USB3.0 and USB3.1, etc.
The terminal member is disposed between the upper insulating shell 110 and the lower insulating shell 120. The terminal member includes a first-polarity conductive terminal 131, a second-polarity conductive terminal 132 and a third-polarity conductive terminal 133. As shown in
Specifically, the structure and quantity of the terminal members and the manner in which they are fixed between the upper insulating shell 110 and the lower insulating shell 120 are not limited here. In this embodiment, when the electrical connector 100 is docked with other electronic devices, the pins of the electronic device pass through the sockets 111 of the upper insulating shell 110 and electrically connect with the first elastic piece portion 1311 of the first-polarity conductive terminals 131, the second elastic piece portion 1321 of the second-polarity conductive terminal 132 and the third elastic piece portion 1331 of the third-polarity conductive terminal 133 in the terminal member.

In this embodiment, the length DC of the central contact portion 1402 of the central conductor 140 exposed to the lower insulating shell 120 is greater than the length D1 of the first outer contact portion 1412 of the first outer conductor 141 exposed to the lower insulating shell 120. The length D1 of the first outer contact portion 1412 of the conductor 141 exposed to the lower insulating shell 120 is greater than the length D2 of the second outer contact portion 1422 of the second outer conductor 142 exposed to the lower insulating shell 120.

It can be seen from
The first outer ring docking portion 2311 of the first outer ring terminal 231 and the first inner ring docking portion 2331 of the first inner ring terminal 233 are disposed correspondingly to the same socket 211. The second outer ring docking portion 2321 of the second outer ring terminal 232 and the second inner ring docking portion 2341 of the second inner ring terminal 234 are arranged correspondingly to the same socket 211. In the two embodiments, the specifications of the terminal member and the manner of being disposed between the first insulating shell 210 and the second insulating shell 220 are not limited here.
In contrast to the previous embodiment, the base 200 of this embodiment is provided with spacers 221 between the first insulating shell 210 and the second insulating shell 220. Due to the arrangement of the spacers 221, the first outer ring terminal 231, the first inner ring terminal 233, the second outer ring terminal 232 and the second inner ring terminal 234 have a certain distance in-between. The terminal docking portions is more difficult to introduce deformations and thus the life could be prolonged.
The present disclosure also discloses an electrical connector assembly including the aforementioned electrical connector 100 and the base 200. Please refer to

In the electrical connector 100, the distance R1 between the first outer contact portion 1412 of the first outer conductor 141 and the central contact portion 1402 of the central conductor 140 is equal to the distance R2 between the central contact portion 1402 of the central conductor 140 and the second outer contact portions 1422 of the second outer conductor 142, and the center of the first outer conductor 141, the center of the central conductor 140, and the center of the second outer conductor 142 are aligned in the same straight line. Therefore, when the electrical connector 100 is assembled with the base 200, if the socket 211 to which the central terminal 230 is docked is regarded as the center of a circle, the sockets 211 corresponding to other terminal members of the base 200 have the same shape of the trajectories of the rotation of the first outer conductor 141 and the second outer conductor 142 of the electrical connector 100. That is, non-directional docking can be achieved between the electrical connector 100 and the base 200.
By means of the structural design between the conductor members of the electrical connector 100 and the base 200, the electrical connector 100 can be assembled as long as the central conductor 140 of the electrical connector 100 is aligned with the socket 211 corresponding to the central terminal 230 of the base 200. It is convenient for users to install and use, so the manufacturer can save the cost caused by providing the fool-proof structure, and the designer can have more flexibility to design the circuit layout.
Please refer to
Due to the difference in the lengths of the conductor members of the electrical connector 100 and the different distances between the terminal members disposed inside the base 200 and the upper surface of the base 200, when the electrical connector 100 is docked with the base 200 at the second angle, the first outer conductor 141 passes through a socket 211 of the first insulating shell 210 and to be coupled to the first outer ring terminal 231 and the first inner ring terminal 233. The first outer conductor 141 passes through another socket 211 of the first insulating shell 210 but is not coupled to the second outer ring terminal 232 and the second inner ring terminal 234. In more detail, the structural design disclosed in the present disclosure enables polarity between the electrical connector 100 and its base 200, and the second angle refers to an incomplete conduction between the conductor member of the electrical connector 100 and the terminal member of the base 200. The difference between the first angle and the second angle lies in the difference in the number of conductive members after docking the electrical connector 100 with the base 200. Taking the embodiment shown in
To sum up, in the electrical connector 100 and its base 200 provided by the present disclosure, the structural design of the contact interface does not have a specific assembly direction, so as to realize non-directional docking and save the cost of the foolproof structure. Furthermore, the designer could have a better flexibility in the circuit layout. In addition, its structural design makes the connector components have polarities, and the number of components conducting between the electrical connector and its base is also different depending on their docking angle. This raises its applicability.
