Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector used for integrating high-definition multimedia interfaces HDMI and DisplayPort. Background Technology

[0002] HDMI is a high-definition multimedia interface, currently the most commonly used advanced fully digital video and audio transmission interface. Its advantages include the ability to transmit uncompressed audio and video signals with excellent transmission quality. HDMI is commonly used in major audio-visual systems such as digital audio players, personal computers, video game consoles, and DVD players. Because it can transmit audio and video signals simultaneously, and these audio and video signals use the same cable, the system installation is simpler and less labor-intensive, making it a very common multimedia interface.

[0003] Another more advanced digital video interface, DisplayPort, is a digital video interface standard promoted by the Video Electronics Standards Association (VESA). Due to its advantages such as no certification or licensing fees, it has gained the support of most manufacturers and plays a pivotal role in the development of new digital audio / video interfaces. It has replaced older computer home theater interfaces such as LVDS, DVI, and VGA, providing high-bandwidth digital video and audio transmission capabilities for both internal and external connections, and is currently the most widely used advanced interface.

[0004] While HDMI and DisplayPort are commonly used, they are two incompatible connection interfaces. However, in current audio-visual equipment, especially computer-related audio-visual systems, both interfaces are almost always required to ensure full functionality. Manufacturers usually include both interfaces when launching audio-visual equipment to meet consumer needs. However, these two interfaces have different numbers of terminals and significantly different widths, meaning they can only be installed separately on audio-visual equipment and cannot be integrated. This makes the arrangement of connectors around the audio-visual system more chaotic and prevents the device from being made thinner and smaller, wasting costs and increasing wiring complexity. Therefore, new connectors must be more sophisticated, ideally integrating the two interfaces. This requires not only meeting existing connector size specifications but also cleverly connecting the original interface terminals, which is an important research and improvement topic in the industry.

[0005] To this end, the applicant previously developed an electrical connector with two audio-visual interfaces and a foolproof design, as specified in Chinese Patent No. 201520947534.5, which can meet the insertion requirements of different interface specifications. However, this electrical connector still has issues with stability and service life after practical application, requiring further improvement. Summary of the Invention

[0006] The purpose of this utility model is to provide an electrical connector that can accommodate male sockets of different sizes and can automatically switch the connected signal to achieve different interface insertion implementations, while improving product stability and service life.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An electrical connector having at least the following characteristics:

[0009] An insulating body, on which signal terminals suitable for different interfaces are assembled.

[0010] The outer iron shell is wrapped around the outside of the insulating body and forms a socket with the insulating body at the front for the insertion of the male connector; the outer iron shell is provided with a trigger pin, which responds adaptively when different male connectors are inserted, thereby switching the connected signal to achieve the insertion of different interface specifications.

[0011] An actuator is assembled on an insulating body and located in a socket. The actuator is driven by an external male connector to change the posture of the trigger pin, causing the trigger pin to make a corresponding response action. The socket is provided with at least a first limiting member, which controls the actuator so that the actuator can be selectively driven by the male connector.

[0012] The above solution is further described as follows: the trigger foot is an elastic arm constructed by partially tearing the outer iron shell. The trigger foot protrudes inward and presses against a preset signal contact on the insulating body to obtain a conductive connection. A pry point is provided at the root of the trigger foot, and a boss is provided on the triggering element. When the triggering element is driven by the male seat, the boss on the triggering element drives the pry point, causing the trigger foot to leave the signal contact, changing the original "0" or "1" signal, thereby switching the connected signal to achieve the insertion of different specifications of interfaces.

[0013] The above solution is further described as follows: the actuating member has a telescopic characteristic in the insertion direction of the male seat; the boss protrudes from the upper side of the actuating member; when the actuating member is driven by the male seat, it moves backward, and the boss moves accordingly and presses and lifts the pry point, causing the trigger foot to leave the signal contact; one side of the boss extends to form a locking platform, which is used to engage with the first limiting member; the first limiting member is pushed open when the male seat is inserted, allowing the locking platform to be released.

[0014] The above solution is further described as follows: the actuating element also has a downwardly extending anti-fooling spring, which is used to prevent the male socket from being inserted incorrectly; the lower end of the anti-fooling spring is engaged with a second limiting member on the inner lower side of the socket; the second limiting member and the first limiting member are pushed open together when the male socket is inserted, so that the anti-fooling spring and the locking plate are released together, so that the actuating element can move backward when driven by the male socket.

[0015] The above solution is further described as follows: the actuating element obtains its telescopic characteristics by being supported by a compression spring. The rear end of the compression spring supports the insulating body, while the front end of the compression spring supports the actuating element. The actuating element is provided with a rearwardly protruding guide post, which is inserted into the interior of the compression spring. The outer side wall of the actuating element is provided with an outwardly protruding buckle, which cooperates with the positioning groove on the outer iron shell to restrict the actuating element from extending forward, so that the front end of the actuating element is stably placed in the insertion port.

[0016] The above solution is further described as follows: the actuating element is a frame-shaped hardware component formed by integral stamping. The actuating element has an inner side wall opposite to the outer side wall and a lower side wall extending downward from the outer side wall and inclined inward. The guide post is located between the inner side wall and the outer side wall, so that the inner side wall and the outer side wall cooperate to restrict the left and right swing of the compression spring. The lower side wall is inserted into the inclined groove of the insulating body and can move back and forth.

[0017] The above solution is further described as follows: the first limiting member is a spring arm extending from the top cover, which is assembled on the outer iron shell. The first limiting member extends into the insertion port through a pre-set clearance hole in the outer iron shell. The first limiting member includes a multi-section bent main body, which has a horizontal section in the middle and a first elastic foot extending forward from the horizontal section. The first elastic foot extends to the front end of the trigger and is lower than the upper side of the trigger. A transverse protrusion is provided on one side of the horizontal section. The transverse protrusion abuts against the rear end of the card holder. When the male seat is inserted, it pushes the first elastic foot, causing the horizontal section to lift the transverse protrusion, thereby releasing the card holder.

[0018] The above solution is further described as follows: the second limiting member is a spring arm constructed by partially tearing and stamping the outer iron shell. The second limiting member has a second elastic foot and a C-shaped hanging groove. The anti-fooling spring is inserted into the C-shaped hanging groove from top to bottom and stopped by the inner bottom of the C-shaped hanging groove. The second elastic foot protrudes into the inside of the insertion port in a cantilever shape, and the second elastic foot is located at the front end of the trigger member. When the male seat is inserted, the second elastic foot is pushed, causing the second limiting member to drive the C-shaped hanging groove to open to the outside of the insertion port, thereby releasing the anti-fooling spring.

[0019] The above solution is further described as follows: the electrical connector is a connector that combines two audio-visual interfaces, the plug end of the insulating body has a tongue, the tongue is located in the socket, and the contact part of the signal terminal is exposed from the upper and lower surfaces of the tongue; the socket is compatible with DisplayPort male connectors and HDMI male connectors for insertion and connection.

[0020] This invention features a trigger foot on the outer iron shell, ensuring a stable and reliable structure. An actuating element is assembled on the insulating body, and a first limiting element is provided in the socket. This first limiting element controls the actuating element, allowing it to be selectively driven by the male connector for accurate operation. The actuating element drives the trigger foot, changing the original "0" or "1" signal, thereby switching the connected signal. This enables the insertion of different interface specifications, achieving the function of switching between two audio-visual interfaces. Simultaneously, the product structure is optimized, improving product stability and service life. Attached Figure Description

[0029] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0030] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] See Figures 1-8 The diagram shown is a preferred embodiment of the present invention. The present invention relates to an electrical connector that integrates two audio-visual interfaces. It comprises an insulating body 1, an outer metal shell 2, and signal terminals 3 arranged on the insulating body 1 for electrical connection. The signal terminals 3 are arranged in an orderly manner and are suitable for connection to different interfaces. The outer metal shell 2 encloses the insulating body 1 and forms a socket 21 at its front with the insulating body 1 for easy male connector insertion. The insertion end of the insulating body 1 has a tongue 13 located in the socket 21, with the contact portion of the signal terminals 3 exposed from the upper and lower surfaces of the tongue 13. The socket 21 is compatible with DisplayPort and HDMI male connectors, achieving the function of switching between two audio-visual interfaces.

[0032] The outer metal shell 2 is equipped with a trigger foot 22, which adaptively responds to different male connector insertions, thereby switching the connected signal to achieve different interface insertion specifications. An actuating element 4 is assembled on the insulating body 1, located in the socket 21 and capable of relative movement. Driven by the external male connector, the actuating element 4 changes the posture of the trigger foot 22, causing it to respond accordingly and switch the connected signal to achieve different interface insertion specifications. The socket 21 is equipped with at least a first limiting member 5, which controls the actuating element 4, allowing it to be selectively driven by the male connector, preventing malfunction and improving practicality.

[0033] In this embodiment, the trigger leg 22 is an elastic arm constructed by partially tearing the outer iron shell, forming an integral structure that is robust and stable. The trigger leg 22 protrudes inward and presses against the preset signal contact 11 on the insulating body 1 to obtain a conductive connection. A pry point 221 is provided at the root of the trigger leg 22, and a boss 41 is provided on the touch element 4. When the touch element 4 is driven by the male seat, the boss 41 on the touch element 4 drives the pry point 221, causing the trigger leg 22 to move away from the signal contact 11, changing the original "0" or "1" signal, thereby switching the connected signal to achieve the insertion of interfaces of different specifications.

[0034] Furthermore, the actuating member 4 has a telescopic characteristic in the insertion direction of the male connector. The boss 41 protrudes from the upper side of the actuating member 4. When the actuating member 4 is driven by the male connector, it moves backward, and the boss 41 moves accordingly and presses and lifts the pry point 221, causing the trigger foot 22 to leave the signal contact 11, adaptively switching signals to realize the insertion of interfaces of different specifications. One side of the boss 41 extends to form a locking platform 42, which is used to engage with the first limiting member 5. The actuating member 4 also has a downwardly extending anti-foolproof spring 43, which has a corresponding anti-foolproof slope for cooperating with the male connector to prevent mis-insertion, such as limiting the HDMI male connector and preventing reverse insertion of the HDMI male connector, thus improving the performance. In this embodiment, the lower end of the anti-fool spring 43 engages with the second limiting member 6 on the inner lower side of the insertion port 21. The second limiting member 6 and the first limiting member 5 are respectively disposed on the upper and lower sides of the actuating member 4. When the male connector is inserted, the second limiting member 6 and the first limiting member 5 are pushed open together, allowing the anti-fool spring 43 and the locking platform 42 to be released together, so that the actuating member 4 can move backward when driven by the male connector. The upper and lower limits are fixed, and the structure is stable and reliable, improving the performance and service life.

[0035] Furthermore, the actuating element 4 achieves its telescopic characteristic through the support of a compression spring 7. The rear end of the compression spring 7 is inserted into a pre-set positioning hole in the insulating body 1 and supports the insulating body 1, while the front end of the compression spring 7 supports the actuating element 4. The actuating element 4 is provided with a rearwardly protruding guide post 44, which is inserted into the interior of the compression spring 7 to increase connectivity. The outer wall of the actuating element 4 is provided with an outwardly protruding buckle 45, which, in conjunction with the positioning groove 23 on the outer iron shell 2, restricts the actuating element 4 from extending forward, so that the front end of the actuating element 4 is stably placed in the insertion port 21, ensuring subsequent male connector insertion drive.

[0036] Furthermore, the actuating element 4 is a frame-shaped hardware component integrally stamped, which has good structural integrity and durability. The actuating element 4 has an inner sidewall 46 opposite to the outer sidewall and a lower sidewall 47 extending downward from the outer sidewall and inclined inward. The guide post 44 is located between the inner sidewall 46 and the outer sidewall, so that the inner sidewall 46 and the outer sidewall cooperate to restrict the left and right swing and twisting of the compression spring 7, ensuring that the compression spring 7 is compressed and ejected smoothly and accurately. The lower sidewall 47 is inserted into the pre-set inclined groove 12 of the insulating body 1 and can move back and forth, further increasing the assembly structure and guidance. In this embodiment, the insulating body 1 is also provided with corresponding adhesive positions to fit and guide the outer sidewall and upper sidewall of the actuating element 4, improving the movement stability of the actuating element 4. The front end of the actuating element 4 forms a flat push end to cooperate with the corresponding externally inserted male contact push.

[0037] The first limiting member 5 is a spring arm extending from the upper cover 8, which is assembled onto the outer iron shell 2. The first limiting member 5 extends into the insertion port 21 through the pre-set clearance hole 24 in the outer iron shell 2. In this embodiment, the upper cover 8 is a metal stamping part, which is superimposed and fastened onto the outer iron shell 2. At the same time, the upper cover 8 is also provided with corresponding fixing feet for fixing the upper plate, thereby increasing the installation performance of the connector. The first limiting member 5 includes a multi-section bent main body. The main body has a horizontal part 51 in the middle section and a first elastic foot 52 extending forward from the horizontal part 51. The horizontal part 51 is relatively attached to the upper side of the touch member 4. The rear end of the horizontal part 51 is connected to the upper cover 8 by bending. The structure is stable, not easily deformed, and durable. A transverse protrusion 53 is provided on one side of the horizontal part 51. The transverse protrusion 53 abuts against the rear end of the card table 42. The abutment points of this structure are sufficient, and the limiting is stable, reliable, and not easily worn. The first elastic foot 52 extends to the front end of the contact member 4 and is lower than the upper side of the contact member 4, so that when the male connector is inserted, the first elastic foot 52 is pushed, causing the horizontal part 51 to lift the transverse protrusion 53, thereby releasing the locking plate 42. The second limiting member 6 is a spring arm formed by partial tearing and stamping of the outer iron shell 2. The second limiting member 6 has a second elastic foot 61 and a C-shaped hanging groove 62. The C-shaped opening of the C-shaped hanging groove 62 faces forward, and the extended end of the anti-fooling spring 43 is suspended and inserted into the C-shaped hanging groove 62 from top to bottom. The C-shaped hanging groove 62 restricts the left and right displacement of the anti-fooling spring 43, ensuring the stability of the anti-fooling spring 43, thereby limiting the HDMI male connector and preventing the HDMI male connector from being inserted backward. At the same time, the inner bottom stop of the C-shaped hanging groove further restricts the rearward movement of the contact member 4. The second elastic foot 61 protrudes into the interior of the socket in a cantilever shape, and the second elastic foot 61 is located at the front end of the actuating member 4. When the male socket is inserted, the second elastic foot 61 is pushed, causing the second limiting member 6 to drive the C-shaped hanging groove 62 to open outward of the socket, thereby releasing the anti-fooling spring 43.

[0038] This invention features a trigger foot directly on the outer iron shell, resulting in a stable and reliable structure. The trigger element is assembled on the insulated main body, and at least the upper and lower side walls of the socket are respectively provided with a first limiting element and a second limiting element. These first and second limiting elements work together to control the trigger element, allowing it to be selectively driven by the male connector for accurate operation. The trigger element drives the trigger foot, changing the original "0" or "1" signal, thereby switching the connected signal to accommodate different interface specifications. This achieves the function of switching between two audio / video interfaces. Furthermore, the product structure is optimized; the one-piece construction not only facilitates manufacturing and assembly but also improves product stability and lifespan.

[0039] Of course, the above detailed description of the present utility model in conjunction with the embodiments is only for illustrating the technical concept and features of the present utility model. Its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it. Therefore, all equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
