Abstract

Disclosed are a connector (10) and a transfer cable (50). The connector (10) comprises a main body (11) and at least one pin (14, 15, 16, 17). A connection surface (111) of the main body (11) is provided with a protruded portion (12) and a recessed portion (13). The at least one pin (14, 15, 16, 17) is exposed on the surface of the protruded portion (12) and the recessed portion (13). The protruded portion (12), the recessed portion (13), and the pins (14, 15, 16, 17) are configured so that the connector (10) and another connector (10') of a same structure are connected in such a manner that during connection the protruded portion (12) of the connector (10) plugs into a recessed portion (13') of the other connector (10'), a protruded portion (12') of the other connector (10') plugs into the recessed portion (13) of the connector (10), and the pins (14, 15, 16, 17) of the connector (10) contact and communicate with pins (14', 15', 16', 17') of the other connector (10'). By providing on one connector (10) both a protruded portion (12) as a male terminal and a recessed portion (13) as a female terminal, the connector (10) does not need to distinguish between polarities. Any two connectors (10) can be connected, thus alleviating user confusion in selection of a connector (10), and enhancing user convenience.

As shown in FIG. 1A, in a first exemplary embodiment of the present invention, an interface 10 is provided, including a main body 11, a boss portion 12, a groove portion 13, and an even number of pins. The boss portion 12 and the groove portion 13 are provided on the insertion face 111 of the main body 11, and the shape and size of the boss portion 12 match the shape and size of the groove portion 13. The even number of pins are divided into two equal groups, which are exposed on the surfaces of the boss portion 12 and the groove portion 13, respectively.

The number and function of the pins can be set as needed. In the embodiment shown in FIGS. 1A through 1E, similar to a standard USB interface, the interface 10 includes four pins 14-17, which are four pins. 14 to 17 are the power supply pin, the ground pin, the positive data pin, and the negative data pin, respectively. The four pins are divided into two equal numbers: a first set of pins (eg, pins 14 and 15) and a second set of pins (eg, pins 16 and 17). Therein, the first set of pins are exposed on the surface of the boss 12, and the second set of pins are exposed on the surface of the groove portion 13.

It is to be noted that although the interface 10 illustrated in FIGS. 1A to 1E has four pins, it should be understood that the present invention is not limited thereto. In a first exemplary embodiment of the invention, interface 10 may have any even number of pins, such as two, six, eight, ten, twelve, and the like. In the case of interface 10 having two pins, the two pins can be a power pin and a ground pin, respectively.

As shown in FIGS. 1D and 1E, when two structurally identical interfaces are interposed, the convex portion 12 of the first interface 10 is inserted into the groove portion 13' of the second interface 10', and the first interface 10 is a first set of pins (eg, pins 14 and 15) on the raised portion 12 and a second set of pins on the recessed portion 13' of the second interface 10' (eg, pins 16' and 17') Contact and conduction; the raised portion 12' of the second interface 10' is inserted into the groove portion 13 of the first interface 10, and the first set of pins on the raised portion 12' of the second interface 10' (eg, The pins 14' and 15') are in contact with and conducting with a second set of pins (eg, pins 16 and 17) on the recess portion 13 of the first interface 10.

The invention simultaneously sets the convex portion 12 as the male end and the concave portion 13 as the female end on one interface, so that the interface no longer distinguishes the male and female polarities, and any two interfaces can be plugged, thereby reducing the user. The trouble of selecting an interface provides users with more convenience. Moreover, when the two interfaces are inserted, the boss portion 12 and the groove portion 13 can function as a mutual fixing, thereby improving the plugging stability.
