Detailed Description

In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 7, the connector of the present disclosure includes a housing 10, an insulator 20, a plurality of terminals 30, a switching mechanism 40, and a detection pin 50.

The housing 10 is a hollow frame, and the housing 10 may be made of metal. A socket 11 is formed at one end of the housing 10, the socket 11 may be sized to accommodate a common high definition multimedia interface plug (hereinafter, referred to as an HDMI plug) and a common display port plug (hereinafter, referred to as a DP plug), the housing 10 may be sized to be the same as a metal housing of a common DP connector, and the housing 10 may also be sized to be the same as a metal housing of a common HDMI connector.

The insulator 20 is disposed in the housing 10, the housing 10 covers the insulator 20, and the insulator 20 may be made of plastic.

A plurality of terminals 30 are provided on the insulator 20, the plurality of terminals 30 being for interfacing with a plurality of pins of an HDMI plug or a plurality of pins of a DP plug. Since the common HDMI plug has 19 pins and the common DP plug has 20 pins, in order to be able to interface with the plurality of pins of the HDMI plug and also interface with the plurality of pins of the DP plug, the number of the plurality of terminals 30 is 20, and the arrangement rule of the plurality of terminals 30 may be the same as that of the terminals of the common DP connector. Preferably, twenty terminals 30 are arranged side by side, one of which is floating when the plug inserted into the connector is an HDMI plug. The plurality of terminals 30 have a first butt-joint end 31 and a second butt-joint end 32, the first butt-joint end 31 is used for butt-joint with a pin of a common HDMI plug or a pin of a common DP plug, the second butt-joint end 32 is used for butt-joint with a circuit board (not shown in the figure) having a chip, the chip performs corresponding processing according to the type of the plug inserted into the connector, if the connector is the HDMI plug, the chip processes HDMI transmission, and if the connector is the DP plug, the chip processes DP transmission.

The switching mechanism 40 is configured to be located at a first position when the plug inserted into the connector is an HDMI plug (the switching mechanism 40 is located at the first position when fig. 2 and 7 show), and located at a second position when the plug inserted into the connector is a DP plug (the switching mechanism 40 is located at the second position when fig. 8 and 9 show).

The detection pin 50 is at least partially disposed in the housing 10 and is configured to output a first signal when the switching mechanism 40 is located at the first position and output a second signal when the switching mechanism 40 is located at the second position. The chip performs HDMI transmission processing based on the first signal, and performs DP transmission processing based on the second signal.

Based on the combination of the switching mechanism 40 and the detection pin 50, the type of the plug inserted into the connector can be detected by using the shape difference between the HDMI plug and the DP plug. For example, the lower left corner of the general DP plug is a right angle, and the lower left corner of the general HDMI plug is an oblique angle, when the DP plug is inserted into the socket 11, since the lower left corner of the DP plug is a right angle, the DP plug will interfere with the slider 41 described later, so as to push the slider 41 to move relative to the insulator 20 in a direction away from the socket 11, and when the HDMI plug is inserted into the socket 11, since the lower left corner of the HDMI plug is an oblique angle, the HDMI plug will not interfere with the slider 41, so that the slider 41 remains stationary.

The elastic member 42 is connected with the sliding member 41, the sliding member 41 is located at the first position when the plug inserted into the connector is an HDMI plug, and the elastic member 42 is in a normal state when the sliding member 41 is located at the first position, where the "normal state" refers to a natural state that is not affected by an external force; the sliding member 41 is located at the second position when the plug inserted into the connector is a DP plug, and the elastic member 42 is compressed when the sliding member 41 is located at the second position, so that when the DP plug is pulled out, the elastic member 42 can drive the sliding member 41 to move toward the socket 11 relative to the insulator 20, so as to reset the sliding member 41. The elastic member 42 may be a spring, and other elastic members having elasticity may be used.

In order to facilitate the switching mechanism 40 to output different signals when different types of plugs are inserted, the detection pin 50 is fixedly disposed on the insulator 20, the sliding member 41 is separated from the detection pin 50 when in the first position (see fig. 7), and the sliding member 41 is in contact with the detection pin 50 when in the second position (see fig. 9).
