Technical field

The present invention relates to the field of interfaces or connectors, and in particular, to a connector and a portable device including the same.

Background technique

With the development of smart devices, users tend to be more specialized, diverse and intelligent products. At the same time, professional functional modules also need to be quickly connected to the intelligent platform, so there is a greater demand for the scalability of smart devices. However, existing portable smart devices are not sufficient for scalable connections. Functionally, existing portable smart devices generally only provide a single connection interface, and provide limited connection functions. For example, when a general smart phone uses a data cable connection, only one of the charging and data transmission functions can be used at the same time.

Summary of the invention

In view of the above technical problems, the present invention proposes a connector that can perform charging and data transmission simultaneously, and has more powerful functions.

In view of the above technical problem, the technical solution of the present invention is to provide a connector mainly comprising a female head and a male head, the female head comprising: a connector housing; and a connector disposed in the connector housing a plurality of sets of female terminals, which are connected across the connector and the connector housing, the female terminal includes a female power terminal and a female signal terminal; and a plurality of female pins, the female pin Connected to the bottom of the connector housing and protruding from the side of the connector housing, and the female pins are in one-to-one correspondence with the female terminals; the male head includes a male housing, and the male housing is provided with a plurality of a male terminal, the male terminal includes a male power terminal and a male signal terminal, and one side of the male housing is connected with a plurality of male pins, and the male pin protrudes from the male housing Side and male terminal One-to-one correspondence; and the female head and the male head form a mating structure with a plug and a snap fit.

Existing portable smart devices, such as smart phones, have terminals on which the terminals do not distinguish between signal terminals and power terminals. Due to the limited number of terminals and the influence of the conventional interface design, a general-purpose interface is generally used. The problem with this general-purpose interface is that the same channel is basically shared during charging and data transmission, so that only one function of charging and data transmission can be realized at the same time. In the connector of the present invention, since the male head includes the male power supply terminal and the male signal terminal, the female head includes the female power supply terminal and the female signal terminal, and the terminal for power transmission is separately provided from the terminal for signal transmission. Charging and data transmission use two different channels, so that charging and data transmission can be performed simultaneously, and the function is more powerful.

In an embodiment of the invention, the bottom of the connector housing of the female head is provided with a first positioning structure for ensuring the positioning accuracy of the connector housing on the first soldering substrate. In a preferred embodiment, the first positioning structures are generally two, which are respectively disposed at two ends of the connector housing. Preferably, the first positioning structure is cylindrical, and the two positioning cylinders respectively cooperate with the two positioning holes on the first welding substrate when positioning.

In a preferred embodiment of the invention, the ends of the connectors of the female connector are provided with guide grooves for the insertion. In practice, it is also possible to provide a guide groove only on one end face of the connector. The main advantage of setting the two ends is that, especially in a fully symmetrical structure, the male and female heads do not need to be distinguished between the two ends during installation. Improve installation and reduce costs.

In a preferred embodiment, the plurality of female terminals are arranged in full symmetry along the length of the connector. The fully symmetrical structure facilitates installation, which helps to reduce the installation error rate and improve the installation efficiency.

In a preferred embodiment, the second positioning structure is generally two, which are respectively connected at two ends of one side of the male housing near the male pin. Preferably, the second positioning structure is cylindrical, and the two positioning cylinders respectively cooperate with the two positioning holes on the second welding substrate when positioning.

In one embodiment of the present invention, the male power terminal is connected in the middle of the male housing, and the male signal terminals are distributed on both sides of the male power terminal.

In another embodiment of the invention, the male signal terminal is disposed in the middle of the male housing, and the male power terminals are distributed on both sides of the male signal terminal.

In addition, the present invention also discloses a portable device having a connector on the back side thereof. Since the existing portable smart device is disposed at the position of the interface, the interface is generally disposed on the bottom surface or the side surface, and when the data line is connected on the bottom surface or the side surface, only limited space is provided, and the connection of the expansion device is greatly restricted. . In the portable device of the present invention, the connector is disposed on the back of the device. The arrangement of the back surface not only solves the problem of space limitation, but also makes the connection device and the original device have a stronger overall sense, and is more convenient to carry, and is not easy to carry. The connection is more reliable due to impacts such as collisions.
