Description

A connector with a locking structure Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a connector with a locking structure. Background Technology

[0002] In the field of electronic equipment, connectors are critical connection components, and their performance significantly impacts the overall efficiency of the equipment. Common connectors generally consist of a matching male and female connector. To ensure the stability of the connection between the male and female connectors, locking mechanisms are typically incorporated into both.

[0003] With the rapid development of technology, electronic devices are constantly moving towards miniaturization. Under this trend, connector products are also becoming increasingly smaller. At the same time, to ensure stable and reliable connections in complex application environments, higher requirements are being placed on the connection locking and retention force of connectors.

[0004] However, traditional locking structures, limited by their own design principles and structural characteristics, can hardly meet the current dual demands for connector miniaturization and high connection locking force. For example, in some precision electronic devices with extremely high requirements for connection stability, conventional locking structures are prone to problems such as loosening of the male and female connectors and poor contact when faced with complex operating conditions such as vibration and impact, which can lead to signal transmission interruption or instability, seriously affecting the normal operation of the equipment.

[0005] Therefore, developing a novel connector locking structure to adapt to the miniaturization trend of electronic devices and meet the requirements of high connection locking force has become an important problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to provide a connector with a locking structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A connector with a locking structure includes a male head, a female head, and a locking structure;

[0009] The locking structure includes:

[0010] The first mating component is located on the male connector;

[0011] The second mating member, corresponding to the first mating member and disposed on the female seat, is used to lock the male head and the female seat by engaging with the first mating member;

[0012] Wherein, at least a portion of at least one of the first docking member and the second docking member is elastic.

[0013] In the above scheme, during connector assembly, at least one of the male head and female head moves and assembles along a predetermined direction (which can also be said to be the length direction of the connector). During this process, the first mating part and the second mating part gradually come into contact and gradually engage, ultimately restricting the relative movement of the male head and female head, and ensuring the stability of the assembled connector.

[0014] In this application, the first and second mating parts are assembled by a snap-fit ​​method, which can not only stably realize the assembly of the male and female heads, but also facilitate quick separation of the two when needed.

[0015] In this application, at least a portion of at least one of the first mating member and the second mating member is elastic, which allows it (described below as the first mating member) to move relative to the male or female connector, thereby adapting to more situations, such as when the size settings of the male and female connectors require the first mating member to avoid the female connector in order to assemble with the second mating member.

[0016] It should be noted that the male and female connectors are conventionally designed, and the principle is similar to existing designs. Even if not explicitly stated in this application, those skilled in the art should know that both the male and female connectors have contact elements (or pin structures).

[0017] This application describes the situation where the male and female connectors cannot move relative to each other after locking, but in actual use, it does not limit the two to moving a small distance relative to each other, such as moving a few millimeters relative to each other in the horizontal direction.

[0018] In a further technical solution, either the first docking member or the second docking member includes a first groove, and the other includes an elastic sheet corresponding to the first groove, wherein at least a portion of the elastic sheet is elastic.

[0019] The locking structure has a locked state:

[0020] In the locked state, at least a portion of the elastic piece is inserted into the first groove to lock the male head and the female head together.

[0021] This embodiment further clarifies the snap-fit ​​assembly method of the first mating part and the second mating part. By snap-fit ​​assembly of the elastic sheet and the first groove, the assembly of the male head and the female head can be stably realized to ensure the stability of the assembled connector, and it is also convenient to quickly separate the two when needed.

[0022] In a further technical solution, the elastic sheet has an inclined surface;

[0023] The locking process of the latch structure includes:

[0024] In the first stage, the inclined surface is subjected to a force that causes the elastic sheet to move;

[0025] In the second stage, the force on the inclined surface disappears, causing the elastic sheet to return to its original position.

[0026] For ease of understanding, Figure 5 is used for illustration. The first groove is located on the male connector, and the elastic plate is located on the female connector. During assembly, the male connector moves closer to the female connector. For the elastic plate, the male connector first contacts the inclined surface facing it, and applies a force to the inclined surface to cause the elastic plate to rotate downward. Then, the elastic plate enters the assembly area and rotates upward to reset and engage with the first groove. This description is for illustrative purposes only; the actual process may be adjusted in some embodiments, such as placing the first groove on the female connector.

[0027] The beveled design allows the male or female connector to apply force to it, causing the elastic plate to move, thus facilitating a compact layout of the male and female connectors and reducing the size of the connector.

[0028] In a further technical solution, the elastic sheet has a first contact surface, and the first groove has a second contact surface corresponding to the first contact surface;

[0029] In the locked state, the first mating surface is in close contact with the second mating surface to restrict the relative movement of the male head and the female head.

[0030] The aforementioned inclined surface is designed to facilitate the engagement and assembly of the first groove and the elastic sheet, while the first and second mating surfaces are designed to prevent the first groove and the elastic sheet from separating during the non-separation phase.

[0031] For ease of explanation and understanding, the process of the above-described embodiment will be explained as follows: After the elastic sheet is rotated upward to reset and engage with the first groove, the first contact surface is tightly attached to the second contact surface. When the male head is reset in the opposite direction, the second contact surface applies a force to the first contact surface, and the first contact surface hinders the reset of the second contact surface, thereby limiting the separation of the male head and the female head.

[0032] In a further technical solution, at least one of the first bonding surface and the second bonding surface is a straight surface.

[0033] Taking the first bonding surface as an example, the first bonding surface being a straight surface can be understood as the length or width direction of the first bonding surface being parallel to the thickness direction of the connector.

[0034] This embodiment further constrains the first bonding surface and the second bonding surface. Taking the first bonding surface as an example, setting it as a straight surface can further increase the difficulty of the second bonding surface pushing the first bonding surface, thereby further improving the stability of the connector after assembly.

[0035] In a further technical solution, the elastic sheet includes an elastic segment and an engaging segment connected together, the engaging segment being used for engaging and assembling with the first groove body;

[0036] The first contact surface is located on the engagement section.

[0037] In this embodiment, the elastic segment is elastic while the locking segment is not. When assembling the connector, the locking segment locks into the first groove, preventing the male head and female head from moving relative to each other. Since the locking segment is not elastic, the stability of the connector after assembly is avoided due to significant deformation of the locking segment.

[0038] The elastic segment is elastic and can undergo significant deformation and automatically reset after the external force disappears. During the deformation process, the elastic segment moves synchronously with the locking segment.

[0039] In a further technical solution, the male head includes a first body and a first cover connected together, and the first groove is disposed on the first cover;

[0040] The female base includes a second main body and a second cover connected together, and the elastic sheet is disposed on the second cover.

[0041] This embodiment further describes the male and female connectors, thereby clarifying the placement of the first groove and the elastic sheet. Both are located within the cover structure, thus avoiding modifications to the main structure. Since the main structure is the body of the male and female connectors, and the aforementioned pin structure is located there, when adjusting the first groove and the elastic sheet, only the cover structure needs to be replaced, which reduces costs.

[0042] A further technical solution is that the first main body and the first cover are integrally formed;

[0043] And / or, the first body and the first cover form a second groove communicating with the first groove, the second groove being used to accommodate a portion of the second body and a portion of the second cover.

[0044] The first body and the first cover are integrally formed, which can improve the structural strength of the male connector, thereby improving the structural strength and connection stability of the connector.

[0045] The second groove can accommodate a portion of the second main body and a portion of the second cover to meet the structural compactness requirements of the connector and achieve miniaturization of the connector.

[0046] In a further technical solution, the second cover has a slot corresponding to the elastic sheet.

[0047] The elastic piece engages with the slot, allowing for quick fixing and removal of the elastic piece.

[0048] In some embodiments, the second body and the second cover can be separated, and the slot can be adjusted by replacing the second cover.

[0049] In a further technical solution, the elastic sheet includes a substrate, an elastic portion, and a protrusion connected in sequence;

[0050] The substrate is engaged and assembled with the slot;

[0051] The protrusion is provided corresponding to the first groove.

[0052] In this embodiment, the elastic structure in the elastic sheet is the elastic part, and the engaging structure is the protrusion. Compared with the engagement of the elastic part and the first groove, the engagement of the protrusion and the first groove can avoid the need to open a large first groove, thus reducing the degree of modification to the corresponding structure.

[0053] The substrate is larger than the elastic part to improve the engagement stability with the slot. The elastic part is larger than the protrusion to improve the structural strength of the elastic sheet.

[0054] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0055] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0056] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0057] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0058] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0059] The working principle and advantages of this utility model are as follows:

[0060] During connector assembly, at least one of the male and female connectors moves along a predetermined direction (which can also be described as the length direction of the connector) for assembly. During this process, the first mating part and the second mating part gradually come into contact and engage, ultimately restricting the relative movement of the male and female connectors and ensuring the stability of the assembled connector.

[0061] In this application, the first and second mating parts are assembled using a snap-fit ​​method, which not only ensures stable assembly of the male and female connectors but also facilitates quick separation when needed. Given the trend towards miniaturization in electronic devices, even with their relatively small size, the first and second mating parts still meet the requirement for high connection locking force.

[0062] In this application, at least a portion of at least one of the first mating member and the second mating member is elastic, which allows it (described below as the first mating member) to move relative to the male or female connector, thereby adapting to more situations, such as when the size settings of the male and female connectors require the first mating member to avoid the female connector in order to assemble with the second mating member.

[0070] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0071] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0072] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0073] Referring to Figures 1-6, a connector with a locking structure includes a male head 1, a female head 2, and a locking structure 3;

[0074] The locking structure 3 includes:

[0075] The first mating part 31 is provided on the male head 1;

[0076] The second docking member 32, corresponding to the first docking member 31 and disposed on the female seat 2, is used to lock the male head 1 and the female seat 2 by engaging with the first docking member 31.

[0077] At least a portion of at least one of the first docking member 31 and the second docking member 32 is elastic.

[0078] During connector assembly, at least one of the male head 1 and the female head 2 moves along a predetermined direction (which can also be said to be the length direction of the connector) for assembly. During this process, the first mating part 31 and the second mating part 32 gradually come into contact and gradually engage for assembly, ultimately restricting the relative movement of the male head 1 and the female head 2, and ensuring the stability of the assembled connector.

[0079] In this application, the first mating part 31 and the second mating part 32 adopt a snap-fit ​​assembly method, which can not only stably realize the assembly of the male head 1 and the female head 2, but also facilitate quick separation when needed. With the trend of miniaturization of electronic devices, even though the first mating part 31 and the second mating part 32 are small in size, they can still meet the requirements of high connection locking force.

[0080] In this application, at least a portion of at least one of the first mating member 31 and the second mating member 32 is elastic, so that it (hereinafter referred to as the first mating member 31) can move relative to the male head 1 or the female head 2, thereby adapting to more situations, such as when the size setting of the male head 1 and the female head 2 requires the first mating member 31 to avoid the female head 2 in order to assemble with the second mating member 32.

[0081] It should be noted that the male connector 1 and the female connector 2 are conventionally configured, and the principle is similar to that of existing devices. Even if not explicitly stated in this application, those skilled in the art should know that both the male connector 1 and the female connector 2 have contact elements (or pin structures 4).

[0082] Referring to Figure 1, in this embodiment, either the first docking member 31 or the second docking member 32 includes a first groove 311, and the other includes an elastic sheet 321 corresponding to the first groove 311, at least a portion of the elastic sheet 321 being elastic.

[0083] The locking structure 3 has a locked state:

[0084] In the locked state, at least a portion of the elastic piece 321 is inserted into the first groove 311 to lock the male head 1 and the female head 2.

[0085] This application describes the first groove 311 provided on the male head 1 and the elastic sheet 321 provided on the female head 2.

[0086] This embodiment further clarifies the snap-fit ​​assembly method of the first mating part 31 and the second mating part 32. By snap-fit ​​assembly of the elastic piece 321 and the first groove 311, the assembly of the male head 1 and the female head 2 can be stably realized to ensure the stability of the assembled connector, and it is also convenient to quickly separate the two when needed.

[0087] Referring to Figures 1 and 2, in this embodiment, the elastic sheet 321 has an inclined surface 3211;

[0088] The locking process of the latch structure 3 includes:

[0089] In the first stage, the inclined surface 3211 is subjected to a force to cause the elastic sheet 321 to move;

[0090] In the second stage, the force on the inclined surface 3211 disappears, causing the elastic sheet 321 to reset.

[0091] For ease of understanding, Figure 5 is used for illustration. The first groove 311 is located on the male connector 1, and the elastic piece 321 is located on the female connector 2. During assembly, the male connector 1 moves closer to the female connector 2. For the elastic piece 321, the male connector 1 first contacts the inclined surface 3211 facing it, and the male connector 1 applies a force to the inclined surface 3211 to cause the elastic piece 321 to rotate downward (or move). Then, the elastic piece 321 enters the assembly area and rotates upward to reset and engage with the first groove 311. This description is for illustrative purposes only; the actual process can be adjusted in some embodiments, such as placing the first groove 311 on the female connector 2.

[0092] The inclined surface 3211 facilitates the application of force by the male connector 1 or the female connector 2 to move the elastic piece 321, thus enabling a compact layout of the male connector 1 and the female connector 2 and reducing the size of the connector.

[0093] It should be noted that, while the elastic sheet 321 is used as the first mating member 31 for explanation, it is also possible that the second mating member 32 applies force to the inclined surface 3211.

[0094] It should also be noted that in some embodiments, the elastic sheet 321 may first move along the horizontal direction (such as the width direction of the connector) and then reset, and this application does not limit this.

[0095] Referring to Figures 1-2, in this embodiment, the elastic sheet 321 has a first contact surface 3212, and the first groove 311 has a second contact surface 3111 corresponding to the first contact surface 3212;

[0096] In the locked state, the first mating surface 3212 is in close contact with the second mating surface 3111 to restrict the relative movement of the male head 1 and the female head 2.

[0097] The aforementioned inclined surface 3211 is provided to facilitate the engagement of the first groove 311 and the elastic sheet 321, while the first mating surface 3212 and the second mating surface 3111 are provided to prevent the first groove 311 and the elastic sheet 321 from separating during the non-separation stage.

[0098] For ease of explanation and understanding, the process described above is based on the following: After the elastic sheet 321 is rotated upward to reset and engage with the first groove 311, the first contact surface 3212 is tightly attached to the second contact surface 3111. When the male head 1 is reset in the opposite direction, the second contact surface 3111 applies a force to the first contact surface 3212, and the first contact surface 3212 prevents the second contact surface 3111 from resetting, thereby restricting the separation of the male head 1 from the female head 2.

[0099] The first bonding surface 3212 and the second bonding surface can be either straight or inclined surface 3211. Taking the first bonding surface 3212 as an example, when it is inclined surface 3211, the inclination angle is smaller than the inclination angle of inclined surface 3211.

[0100] In this embodiment, at least one of the first bonding surface 3212 and the second bonding surface 3111 is a straight surface.

[0101] Taking the first mating surface 3212 as an example, the fact that the first mating surface 3212 is a straight surface can be understood as the length or width direction of the first mating surface 3212 being parallel to the thickness direction of the connector.

[0102] This embodiment further constrains the first mating surface 3212 and the second mating surface 3111. Taking the first mating surface 3212 as an example, setting it as a straight surface can further increase the difficulty for the second mating surface 3111 to push the first mating surface 3212, thereby further improving the stability of the connector after assembly.

[0103] In some embodiments, both the first bonding surface 3212 and the second bonding surface 3111 are straight surfaces.

[0104] Referring to Figure 3, in this embodiment, the elastic sheet 321 includes an elastic segment 3213 and an engaging segment 3214 connected to each other, and the engaging segment 3214 is used to engage with the first groove 311 for assembly.

[0105] The first contact surface 3212 is provided on the engagement section 3214.

[0106] In this embodiment, the elastic segment 3213 is elastic while the locking segment 3214 is not elastic. When assembling the connector, the locking segment 3214 locks into the first groove 311, so that the male head 1 and the female head 2 cannot move relative to each other. Since the locking segment 3214 is not elastic, the stability of the connector after assembly is avoided due to significant deformation of the locking segment 3214.

[0107] The elastic segment 3213 is elastic and can undergo significant deformation and can automatically reset after the external force disappears. During the deformation process, the elastic segment 3213 moves synchronously with the engaging segment 3214.

[0108] In some embodiments, the size of the elastic segment 3213 is larger than the size of the engaging segment 3214.

[0109] In some embodiments, the elastic segment 3213 is a metal spring.

[0110] In some embodiments, the engaging segment 3214 also has elastic deformation capability, but it is weaker than that of the elastic segment 3213.

[0111] Referring to Figure 6, in this embodiment, the male head 1 includes a first body 11 and a first cover 12 connected together, and the first groove 311 is disposed on the first cover 12;

[0112] The female base 2 includes a second main body 21 and a second cover 22 connected to each other, and the elastic sheet 321 is disposed on the second cover 22.

[0113] This embodiment further describes the male connector 1 and the female connector 2, thereby further clarifying the setting positions of the first groove 311 and the elastic sheet 321. Both are set in the cover structure, thus avoiding the need to modify the main structure. Since the main structure is the main body of the male connector 1 and the female connector 2, the aforementioned pin structure 4 is set here. When adjusting the first groove 311 and the elastic sheet 321, only the cover structure needs to be replaced, which can reduce costs.

[0114] Referring to Figure 6, in this embodiment, the first main body 11 and the first cover 12 are integrally formed;

[0115] And / or, the first body 11 and the first cover 12 enclose each other to form a second groove 5 that communicates with the first groove 311, and the second groove 5 is used to accommodate a portion of the second body 21 and a portion of the second cover 22.

[0116] The first body 11 and the first cover 12 are integrally formed, which can improve the structural strength of the male head 1, thereby improving the structural strength and connection stability of the connector.

[0117] The second groove 5 can accommodate a portion of the second main body 21 and a portion of the second cover 22 to meet the structural compactness requirements of the connector and achieve miniaturization of the connector.

[0118] In some embodiments, the first body 11 and the second body 21 are plastic bodies.

[0119] In some embodiments, the first cover 12 is a metal cover.

[0120] In some embodiments, the second cover 22 is a plastic cover.

[0121] In some embodiments, the elastic sheet 321 is a metallic elastic structure, such as a nickel-titanium alloy, a nickel-titanium alloy, or spring steel.

[0122] Referring to Figure 6, in this embodiment, the second cover 22 is provided with a slot 221 corresponding to the elastic piece 321.

[0123] The elastic piece 321 engages with the slot 221, enabling quick fixing and disassembly of the elastic piece 321.

[0124] In some embodiments, the second body 21 and the second cover 22 can be separated, and the slot 221 can be adjusted by replacing the second cover 22.

[0125] Referring to Figure 6, in this embodiment, the elastic sheet 321 includes a substrate 3215, an elastic portion 3216, and a protrusion 3217 connected in sequence;

[0126] The substrate 3215 is engaged with the slot 221;

[0127] The protrusion 3217 is provided corresponding to the first groove 311.

[0128] In this embodiment, the elastic structure in the elastic sheet 321 is the elastic part 3216, and the engaging structure is the protrusion 3217. Compared with the engagement of the elastic part 3216 with the first groove 311, the engagement of the protrusion 3217 with the first groove 311 can avoid opening a large first groove 311, thereby reducing the degree of modification to the corresponding structure.

[0129] The size of the substrate 3215 is larger than the size of the elastic portion 3216 to improve the engagement stability with the slot 221. The size of the elastic portion 3216 is larger than the size of the protrusion 3217 to improve the structural strength of the elastic sheet 321.

[0130] In some embodiments, substrate 3215 is a silicone plate.

[0131] In some embodiments, the edges of the protrusion 3217 are elastic.

[0132] In some embodiments, the substrate 3215 and the elastic portion 3216 are arranged at an angle to facilitate the movement of the elastic portion 3216 under force.

[0133] It should be noted that the locking structure 3 in some embodiments of this application is particularly suitable for connectors with smaller size and will not occupy much extra space, such as the first groove 311 which does not occupy space separately.

[0134] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
