[0038] The utility model will be described in detail below in combination with specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the utility model.

[0039] It should be noted that, unless otherwise explicitly specified and limited, the terms "center", "longitudinal", "transverse", "upper", "lower", "vertical", "horizontal", "inner", "outer", and the like used in the specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely intended to facilitate the description of the utility model and simplify the description, and therefore cannot be understood as limiting the indicated device or element to have a specific orientation, to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. The terms "mounting", "connection", "connection", "fixing" and the like should be broadly understood, for example, they can be fixedly connected, or detachably connected, or integrally connected; they can be mechanically connected, or electrically connected; they can be directly connected, or indirectly connected through an intermediate medium. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features; therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features; the meaning of "multiple" is two or more; "and / or" includes any and all combinations of one or more related listed items. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0040] With the continuous development of digital technology, in the field of digital video transmission, Display Port transmission protocol and High Definition Multimedia Interface transmission protocol are the current mainstream specification protocols.

[0041] Since Display Port and HDMI belong to different transmission protocols, they have different application limitations. Therefore, the Display Port plug and the HDMI plug at the physical interface level have different appearance specifications and connection terminal configurations.

[0042] In order to improve the integration, by taking advantage of the fact that the size of the Display Port plug is larger than that of the HDMI plug, some electrical connectors are designed to have a larger cavity to simultaneously satisfy and compatible with the insertion of the Display Port plug and the HDMI plug.

[0043] However, the cavity with a larger space is usually designed for the profile of the Display Port plug, which cannot be adapted to the size of the HDMI plug, resulting in that the HDMI plug cannot be effectively constrained when being inserted, and further causing unexpected shaking or movement. This has a great impact on the actual use experience.

[0044] Therefore, the embodiment of the utility model provides a kind of electric connector. Its by the constraint component of changeable form realizes the structural size change of the cavity in electric connector, to make electric connector can simultaneously provide good constraint and guide for different appearance specifications plug, avoid the problem of shaking during plug insertion process, effectively improve use experience.

[0045] Further, an additional foolproof component is provided, which realizes the insertion foolproof function of the HDMI plug while not affecting the insertion of the large-size Display Port plug.

[0046] Figure 1 The structural schematic diagram of the electric connector provided by the embodiment of the utility model. Figure 2 As shown in Figure 1 The electric connector shown removes part of the shell. The electric connector can be suitable for and simultaneously compatible with the insertion of two different appearance specifications plugs of the first plug and the second plug, and simultaneously provide good constraint and guide for the two plugs.

[0047] Exemplarily, the first plug is a Display Port plug, and the second plug is an HDMI plug. However, those skilled in the art can understand that, based on the same design idea, after adjusting the size specifications of the components of the electric connector, it can be applied to other plugs with different appearance sizes, and is not limited to Display Port plugs and HDMI plugs, as long as the size of the second plug is smaller than that of the first plug.

[0048] As shown in Figure 1 And Figure 2 The electric connector includes a shell 10 and a constraint component 20.

[0049] The shell 10 is the main structure of the entire electric connector, and provides the basic appearance of the entire electric connector. Its inside forms a cavity with a specific size and shape as a containing space for accommodating the plug. In the embodiment, the shape and size of the cavity are set to be adapted to the first plug.

[0050] For ease of description, as shown in Figure 3As shown, the two opposite sidewalls of the cavity in the width direction x can be referred to as the first sidewall S1 and the second sidewall S2, respectively, while the two opposite walls in the height direction y can be referred to as the bottom wall B1 and the top wall B2, respectively.

[0051] The following combination Figure 6 The specific composition of the shell 10 is described in detail. Figure 6 As shown, the housing 10 may include: an inner shell 11, a plastic body 12, and an outer shell 14.

[0052] The inner shell 11 is a hollow structural component. It forms the basic framework of the electrical connector, providing structural support and shielding protection. The front port of the inner shell 11 forms the opening for the plug to be inserted into the cavity.

[0053] Specifically, based on actual usage needs, the inner shell 11 can be equipped with one or more functional structures to help improve the user experience of the electrical connector. For example, one corner of the front port of the inner frame 11 can be set as an asymmetrical notch, thus matching the notch of the DisplayPort plug. This guides the first plug to be inserted in the set direction, preventing it from being inserted in a non-set direction, thus providing a certain degree of foolproof protection.

[0054] The plastic body 12 is an insulating component that secures the interior of the inner shell 11. It mates with the inner wall of the inner shell 11 to form a receiving space for accommodating the plug.

[0055] For details, please continue reading. Figure 1 The plastic body 12 also has a tongue plate 13 protruding from the cavity. The tongue plate 13 may be provided with several different contact terminals. After the plug is inserted into place and engages with the tongue plate 13, it establishes an electrical connection with the electrical connector through the contact terminals on the tongue plate.

[0056] The outer shell 14 is fixedly disposed on the outer surface of the inner shell 11, covering a portion of the outer surface area of ​​the inner shell 11 to form a complete shell. Specifically, the outer shell 14 can be fixed to the outer surface of the inner shell 11 using any suitable type of detachable fixing method (e.g., snap-fit ​​connection) as needed.

[0057] Please refer to the following during the actual assembly process. Figure 5 First, the insulating body 12 is assembled and fixed to the rear end of the inner shell 11, together forming a receiving space for accommodating the plug. Then, the outer shell 14 is assembled and fixed to the outer surface of the inner shell 11, forming a complete electrical connector.

[0058] Please continue reading. Figure 2The constraint component 20 is a structural component protruding out of the cavity when the first plug is not inserted into the cavity. It has the ability to elastically deform and change its shape when different plugs are inserted, thereby providing constraint and guidance for different plugs.

[0059] In one aspect, the constraint component 20 protruding out of the cavity forms a stop structure 21 to provide constraint and guidance for the second plug.

[0060] Specifically, as shown in Figure 3 the stop structure 21 is formed on one side of the constraint component 20, and the interval L1 between the stop structure 21 and the second side wall S2 in the width direction y is adapted to the size of the second plug in the width direction.

[0061] “adapted” means that the size of the plug receiving space is substantially equivalent or consistent with the size of the plug when the plug is inserted in the correct set direction. For example, the interval L1 is approximately equivalent to the width of the long side of the HDMI plug.

[0062] Therefore, through the above two width direction size settings, the stop structure 21 of the constraint component 20 can play a good constraint role on the second plug, ensuring that the second plug will not shake, but can be inserted into the cavity and engaged with the tongue plate 13 under the constraint and guidance of the stop structure 21 and the second side wall S2.

[0063] On the other hand, please continue to refer to Figure 2 In order to ensure that the constraint component 20 protruding out of the cavity does not interfere with and hinder the insertion of the first plug with a larger size, the constraint component 20 further forms a guide-in structure 22.

[0064] The “guide-in structure” is a functional structure that can form a suitable contact surface between two structural components when they are in physical contact, so that the direction of part of the force is changed.

[0065] Therefore, when the first plug is inserted into the cavity, it can be in physical contact with the guide-in structure 22 of the constraint component. The guide-in structure 22 is pressed by the first plug, causing the constraint component 20 to be pressed and deformed, and leaving the cavity, so that it does not limit the insertion of the first plug.

[0066] Specifically, as shown in Figure 3 in the width direction x, the guide-in structure 22 is arranged between the stop structure 21 and the first side wall S1. Such a position setting can ensure that the first plug can be in physical contact with the guide-in structure 22 only when it is inserted into the cavity, while the second plug will not be in physical contact with the guide-in structure 22 when it is inserted into the cavity, thereby ensuring that the constraint component 20 can play a constraint and guidance role when the second plug is inserted.

[0067] By means of the constraint member arranged in the electrical connector, a stop structure can be provided when the second plug of smaller size is inserted, providing a good constraint effect, while when the first plug of larger size is inserted, the constraint member can be made to leave the cavity by means of the lead-in structure, without causing unnecessary obstruction and limitation.

[0068] In some embodiments, in order to further improve the actual use effect of the electrical connector, please continue to refer to Figure 1 and Figure 2 , the electrical connector can further comprise a foolproof member 30.

[0069] The foolproof member 30 is also a structural member protruding from the cavity. It is arranged at an appropriate position to achieve the insertion foolproof function for the second plug.

[0070] Specifically, as Figure 3 shown, in the width direction x, the interval L2 between the foolproof member 30 and the second side wall S2 is arranged to be smaller than the interval L1 between the stop structure 21 and the second side wall S2.

[0071] By means of such width interval arrangement, when the second plug is inserted into the cavity in a non-set direction, since the interval L2 of the foolproof member 30 is smaller than the maximum length dimension of the second plug (approximately equivalent to L1). Therefore, at least a part of the foolproof member 30 will be in abutment with the second plug, thereby playing a role in limiting the continued insertion of the second plug, reminding the user of the insertion foolproof effect of adjusting the insertion direction.

[0072] Specifically, please continue to refer to Figure 1 and Figure 2 , based on the different functions to be achieved by the structure, the foolproof member 30 comprises a foolproof elastic body 31 and a foolproof abutment portion 32.

[0073] The foolproof elastic body 31 is a structure with elastic recovery capability, which connects and supports the foolproof abutment portion 32, and is also provided with a lead-in structure, so that the foolproof member 30 protruding from the cavity can leave the cavity along with the insertion of the first plug, avoiding affecting and hindering the insertion of the first plug.

[0074] In some embodiments, the lead-in structure formed by the foolproof elastic body 31 and the lead-in structure 21 formed by the constraint member 20 can adopt the same structural design. Alternatively, the two lead-in structures can also adopt different structural designs, depending on the actual application needs. For example, as Figure 4 shown, the lead-in structure 21 formed by the constraint member 20 is an arc surface formed at the end, and the lead-in structure formed by the foolproof elastic body 31 is an inclined surface inclined at a certain angle.

[0075] The fool-proof abutting part 32 is formed extending outwardly from one side of the fool-proof elastic body 31. It is the part of the fool-proof part 32 closer to the second side wall S2, which is used to limit the second plug inserted in the non-set direction from continuing to be inserted.

[0076] In other words, the fool-proof abutting part 32 is located between the fool-proof elastic body 31 and the second side wall S2. When the second plug is inserted in the cavity in the non-set direction, the fool-proof abutting part 32 protruding from the cavity will abut against the second plug, so that the second plug cannot continue to be inserted.

[0077] It should be noted that the position of the fool-proof elastic body 31 can be reasonably set to ensure that the second plug inserted in the cavity in the non-set direction still does not physically contact it, thereby avoiding the situation that the second plug pushes the fool-proof part 30 out of the cavity.

[0078] For example, please continue to refer to Figure 3 In the width direction x, the distance L4 between the lead-in structure formed by the fool-proof elastic body 31 and the first side wall S1 is designed to be smaller than the distance L3 between the stop structure 21 and the first side wall S1, so as to ensure that the inserted second plug does not contact the fool-proof elastic body 31.

[0079] Preferably, please continue to refer to Figure 2 The above-mentioned constraint part 20 and / or fool-proof part 30 can be realized by an integrated sheet-shaped elastic part formed by the shell 10. Such an integrated sheet-shaped elastic part can be conveniently obtained by machining the metal shell, and the overall implementation cost is low and the structure is reliable.

[0080] For example, as shown in Figure 2 and Figure 3 , the sheet-shaped elastic part protruding from the top wall B2 of the inner shell 11 into the cavity can be used as the constraint part 20. Among them, the end face opposite to the second side wall forms the above-mentioned stop structure 21, and the end part close to the opening end of the cavity forms the lead-in structure 22. The sheet-shaped elastic part protruding from the bottom wall B1 of the inner shell 11 into the cavity can be used as the fool-proof part 30.

[0081] Alternatively, the positions of the above-mentioned constraint part 20 and fool-proof part 30 can also be replaced with each other, or protrude into the cavity from other side walls, as long as the lead-in structure can achieve the same technical effect.

[0082] In order to help reliably identify the type of plug currently inserted into the electrical connector, in some embodiments, as shown in Figure 5 , the contact terminals arranged on the tongue plate 13 include identification terminals 15.

[0083] The identification terminal 15 is located on the side of the tongue plate 13 close to the second side wall S2. It is designed to generate different identification electrical signals based on the insertion of different plugs.

[0084] For example, when the first plug is engaged with the tongue plate, the identification terminal 15 can be kept in contact under the action of the first plug to generate a specific first electrical signal. When the second plug is engaged with the tongue plate, the identification terminal 15 is bounced away and does not contact each other to generate a second electrical signal different from the first electrical signal.

[0085] Alternatively, the identification terminal 15 can also be provided with other settings or adjusted according to actual needs, as long as different identification electrical signals can be generated when the first plug is engaged with the tongue plate / the second plug is engaged with the tongue plate.

[0086] In order to fully describe the implementation principle of the electrical connector provided by the embodiment of the utility model, the actual use process of the electrical connector when different plugs are inserted is described in detail below.

[0087] As shown in Figure 7 and Figure 8 , when the first plug P1 is inserted into the electrical connector 1 in a set direction, on the one hand, the lead-in structure of the constraint component 20 will physically contact the first plug P1. Under the extrusion of the first plug P1, the lead-in structure drives the driving constraint component 20 to move upward away from the cavity, so that the first plug P1 can be smoothly inserted.

[0088] On the other hand, the lead-in structure (formed by the fool-proof elastic body) of the fool-proof component 30 will also physically contact the first plug P1, and similarly under the extrusion of the first plug P1, the driving force of the lead-in structure drives the fool-proof component 30 to move downward away from the cavity, so that the fool-proof component 30 is extruded out of the cavity and does not hinder and limit the first plug.

[0089] After the first plug P1 is pulled out of the electrical connector, the constraint component 20 and the fool-proof component 30 can restore to the state of protruding from the cavity under the action of their own elastic force.

[0090] In some embodiments, please continue to refer to Figure 7 and Figure 8 , the first plug P1 can also be provided with a fixing structure P11 to improve the connection reliability between the first plug and the electrical connector.

[0091] The fixing structure P11 is an inclined surface with a predetermined angle on the side close to the end face of the first plug P1, and is an abutting surface on the other side of the end face of the first plug P1.

[0092] During the insertion of the first plug P1 into the electrical connector, the inclined surface of the fixing structure P11 retracts under the pressure of the housing 10, allowing the first plug P1 to be inserted smoothly. Once the first plug is fully inserted, the fixing structure P11 pops back out, protruding from the housing 10 through the corresponding notch 16. At this point, the abutting surface of the fixing structure P11 abuts against the housing 10, ensuring that the first plug P1 will not detach from the electrical connector.

[0093] When it is necessary to remove the first plug P1, the fixing structure P11 can be manually squeezed until it retracts and no longer protrudes from the housing 10, and then the first plug P1 can be removed from the electrical connector.

[0094] like Figure 9 and Figure 10 As shown, when the second plug P2 is inserted into the electrical connector 1 in a set direction, the stop structure 21 formed by the constraint member 20 will contact the side of the second plug P2, restricting the movement of the second plug P2 in the width direction.

[0095] like Figure 11 As shown, under the constraint and guidance provided by the stop structure 21 and the second side wall S2, the second plug P2 can be smoothly and accurately inserted into the receiving space until it engages with the tongue plate 13.

[0096] like Figure 12 and Figure 13 As shown, when the second plug P2 is inserted in a non-designated direction, the second plug P2 will be restricted by the foolproof abutment of the foolproof component 30. The foolproof abutment 32 restricts the second plug P2 from being inserted further by abutting, thereby reminding the user to adjust the insertion direction of the second plug, thus serving as a foolproof insertion prevention function.

[0097] Based on the electrical connector provided in one or more of the above embodiments, this utility model further provides an electronic device. This electronic device is equipped with the electrical connector as a multi-functional interface, supporting and compatible with communication connections using two different plug specifications. Furthermore, the electrical connector provides good constraint and guidance when using both the first and second plugs, effectively preventing the second plug from wobbling during insertion.

[0098] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
