Composite socket connector and composite plug connector connected thereto

This creation is about a composite socket and plug connector that are docked with each other.

On August 11, 2014, the USB Association announced a new type of electrical connector. The plug connector can be inserted into the corresponding socket connector in both directions, and the socket connector can transmit USB2.0 and USB3.1 signals. The connector is named USB Type C connector. According to the current industry reports, this electrical connector has great development potential in the future, and various connector manufacturers are actively developing in cooperation with system manufacturers.

After several years of development, USB Type-C is currently widely used in mobile phones, computers and other devices, and also used in other industries, such as televisions, cameras, VR and other devices. Device developers hope that it can transmit more types of For signals, the use of USB Type-C extended forms is becoming more and more inevitable, such as the left and right USB Type-C composite connector announced by CN303647497S, which can transmit two USB Type-C signals.

However, in actual use, there are different types of signals, such as data signals, audio signals, video signals, power signals, detection signals, etc. The data signals alone have different rates. Therefore, I hope to design a composite connector that is parallel to the standard USB Type-C, which is beautiful and can also transmit signals different from the USB Type-C signal.

Compared with the prior art, this creation has the following beneficial effects: the socket / plug connector has the same butt tongue plate and fool-proof inner side, so that the connector has a smooth appearance, and at the same time has low cost under the condition of preventing mis-mating The advantages.

The present invention discloses a pair of a composite socket connector 100 and a composite plug connector 500 that are matched with each other, as shown in the first figure. The socket connector 100 is used to be installed on a circuit board P1 in an electronic device such as a computer and VR, and the composite plug connector 500 is used to be installed on a circuit board P2 in a device such as an adapter or a docking station.

As shown in the first to third figures, the socket connector 100 includes a first butt tongue plate 11 and a second butt tongue plate 12 extending forward, a shell 3 surrounding the first and second butt tongue plates, and a conductive terminal 2 . The first and second docking tongue plates have the same structure and are flush with each other. The conductive terminals 2 include two sets of contact portions 21 respectively arranged on the first and second docking tongue plates. The housing 3 has a first inner wall surface 311 and a second inner wall surface 312 parallel to each other up and down, and a first inner side surface 313 and a second inner side surface 314 connecting left and right ends of the first and second inner wall surfaces. The two inner wall surfaces 311 and 312, the first and second inner side surfaces 313 and 314, and the first and second butt tongue plates 11, 12 form a left and right transverse butt cavity 301. The second inner wall surface 312 is further provided with a foolproof block 316 protruding toward the docking cavity, and the foolproof block 316 is located between the first and second docking tongue plates 11 and 12. The first inner side surface 313 and the second inner side surface 314 are symmetrical to each other. The first butt tongue plate 11 and the first inner side surface 313 have a first horizontal distance L1, and the second butt tongue plate 12 and the second inner side surface 314 have a second level. The distance L2 and the second horizontal distance L2 are smaller than the first horizontal distance L1 to form a fool-proof function portion. As shown in the first and third figures, the plug connector 500 has a composite plug connector 501 matched with the docking cavity 301, which includes two pairs of interfaces 502 and 503 arranged laterally and spaced apart from each other, and enclosing to form the connector. The two pairs of interface walls 51 have the same structure. The thickness of the left wall 514 in the wall 51 is smaller than the thickness of the right wall 513 in the wall. The lower wall 512 in the wall has a fool-proof notch 516. In this way, the outer wall surface of the composite plug connector 501 matches the inner wall surface and the inner side surface of the docking cavity 301 of the socket connector.

In a specific embodiment, the first mating tongue plate 11 and its supporting conductive terminals and the shell are set to the structure and size of the USB Type-C socket connector to form an independent first plug interface 3011 for a standard USB Type-C Plug in. At the interval of the foolproof block 316, the second docking tongue plate 12 and its supporting conductive terminals and the shell also form a second opening 3012, but the second opening 3012 cannot independently plug a plug, and it is connected to the first docking tongue plate 11 together form a composite plug-in surface, which corresponds to the docking cavity 301, for the insertion of the composite plug connector 500. The shape and size of the second docking tongue plate 12 are the same as those of the first docking tongue plate 11. The terminals are the same, but the conductive terminals of the second docking tongue 12 are used to transmit non-USB Type-C signals different from USB Type-C signals. Therefore, the composite interface is used to expand non-USB Type-C signal transmission. The first plug interface 3011 can be used to insert a standard USB Type-C plug in both directions. When a composite plug is inserted, the reverse plug cannot be allowed. The foolproof block 316 prevents the reverse plug of the composite plug. At the same time, because the first and second docking tongue plates have the same structure, it is necessary to prevent the standard USB Type-C from being inserted into the second opening 3012 and retract the second side 314 by a certain distance, even if L2 <L1, making the standard USB Type-C unable to Insert the second opening 3012. This arrangement makes the left and right structures of the composite plug look almost the same to the naked eye, the structure is relatively smooth and beautiful, and it has a fool-proof effect in essence.

In the new model, it can be seen that the first and second docking tongue plates 11 and 12 have the same structure and the same number of conductive terminals. In actual mass production, the development of a set of molds can be achieved, which can greatly reduce the cost of mold opening. At the same time, since independent USB Type-C socket connectors have been manufactured in large quantities in the industry, the greater benefit of this new model is that it only needs to redesign the shell 3 and directly assemble the two independent USB Type-C cores that have already been opened. The shell is enough to avoid redundancies that cost millions of mold development costs.

In a preferred embodiment, the first and second horizontal distances differ by 0.15 mm. The fool proof block 316 has a first inclined surface 3162 facing the first butt tongue plate 11 and a second surface 3163 facing the second butt tongue plate 12, the first An inclined surface is symmetrically arranged corresponding to the first inner side surface 313. In this way, a situation where the composite plug connector is partially thin can be avoided. Viewed from the left and right directions, the top surface 3164 of the foolproof block 316 is located within the upper and lower surfaces of the first docking tongue plate 11.
