Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to a socket connector, a plug connector, a connector device, electrical equipment, and a vehicle. Background Technology

[0002] Electrical connector assemblies typically consist of a female socket and a male plug. The female socket and male plug are generally connected to different electrical devices. Different electrical devices are electrically connected by plugging the female socket and male plug into each other. This plugging method also facilitates the disassembly and maintenance of the equipment. To ensure proper mating, connector assemblies often use slots to restrict their connection direction.

[0003] However, in application environments where the connector installation location is not visible or difficult to reach, it is difficult to determine whether the connector is correctly aligned and inserted by relying solely on vision or touch, which can easily lead to connection failure or damage. Utility Model Content

[0004] This application provides a socket connector, a plug connector, a connector device, an electrical device, and a vehicle to facilitate the connection of plugs and sockets in environments that are invisible or difficult to access, thereby at least partially solving the aforementioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a socket connector is provided, comprising: a socket body having a plug portion, the plug portion having a plug hole and a limiting groove, the inner wall surface of the plug hole having a guide structure, the limiting groove extending along the axial direction of the plug hole, and the guide structure being configured to guide the guide portion of the plug connector to align with the limiting groove during the plug-in connection of the plug connector and the socket connector.

[0006] Optionally, the plug portion is rotatably disposed on the socket body.

[0007] Optionally, the guide structure has a guide surface for sliding contact with the guide portion.

[0008] Optionally, along the insertion direction of the insertion hole, the guide surface extends spirally to the limiting groove on the inner wall surface of the insertion hole.

[0009] Optionally, the guide surface has a first end that is flush with the opening end of the insertion hole.

[0010] Optionally, the guide surface further has a second end, which is smoothly connected to the limiting groove.

[0011] Optionally, at least two limiting grooves are symmetrically provided on the outer peripheral wall of the insertion hole, and the guide surface corresponds one-to-one with the limiting groove, and the two guide surfaces corresponding to the two symmetrically provided limiting grooves rotate in opposite directions.

[0012] Optionally, the guide structure and the insertion part are integrally injection molded.

[0013] Optionally, the width of the guide surface ranges from 0.3 mm to 1 mm.

[0014] Optionally, the width of the guide surface is in the range of 0.4mm to 0.5mm.

[0015] Optionally, the length of the guide structure in the axial direction of the insertion part ranges from 5mm to 9mm.

[0016] Optionally, the guide structure is configured to have an axial length of 7 mm in the insertion portion.

[0017] Optionally, the width of the limiting groove is in the range of 2mm to 5mm.

[0018] Optionally, the width of the limiting groove is configured to be 3.8 mm.

[0019] According to a second aspect of this application, a plug connector is provided, including a plug body having a mating portion and a guiding portion. The mating portion is used to engage with a plug hole in a socket connector described in the first aspect. The guiding portion is disposed on the outer side wall of the mating portion and engages with a limiting groove.

[0020] According to a third aspect of this application, a connector device is also provided, including the socket connector described in the first aspect above; and / or the plug connector described in the second aspect above.

[0021] According to a fourth aspect of this application, an electrical appliance is also provided, including the connector device described in the third aspect above.

[0022] According to a fifth aspect of this application, a vehicle is also provided, including the electrical equipment described in the fourth aspect above.

[0023] The socket connector of this application embodiment has a guiding structure on the inner wall of the insertion hole. This guiding structure guides the guide portion of the plug connector to align with the limiting groove during the insertion process, thus providing a self-guiding positioning design to assist in the insertion process. This technical solution can reduce insertion deviations caused by human error to a certain extent in application environments where the installation position is not visible or difficult to directly observe and operate. Specifically, the guiding structure, as a pre-positioning guiding element, slides with the guide portion during the insertion process, causing the guide portion to gradually move along a set trajectory towards the correct insertion direction of the limiting groove, thereby improving the alignment accuracy and insertion success rate of the plug connector.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0036] According to a first aspect of this application, a socket connector is provided; please refer to... Figures 1-4 .

[0037] Combination Figure 1 and Figure 2 The socket connector includes a socket body 1, which has a plug portion 11. The plug portion 11 has a plug hole 111 for inserting a plug connector. To ensure effective alignment of the plug connector and socket connector during insertion, the plug portion 11 also has a limiting groove 112. This limiting groove 112 extends axially along the plug hole 111 and serves to limit and guide the guide portion 22 in the plug connector during insertion. Exemplarily, the limiting groove 112 penetrates the wall of the plug hole 111 radially and the edge of the end wall of the plug hole 111 axially.

[0038] Furthermore, to improve the alignment guidance capability during the initial insertion stage, a guide structure 3 is provided on the inner wall surface of the insertion hole 111. It should be understood that the guide structure 3 being located on the inner wall surface of the insertion hole 111 means that it is a guide formed on a continuous or partial area of ​​the inner wall of the insertion hole 111, rather than being located within the groove wall of the limiting groove 112 or at other non-inner wall locations of the socket connector. Simultaneously, the guide structure 3 does not disrupt the continuity of the wall of the insertion hole 111. Instead, without altering the overall structural strength of the insertion hole 111, it provides effective sliding guidance for the guide portion 22 during insertion by directional processing or shaping of the inner wall surface of the insertion hole 111. This arrangement is not only more compact and reliable in structure but also reduces structural weaknesses caused by other arrangement forms—such as notch forms—thus further improving the guiding stability and overall connection strength during the connection process. Therefore, it is important to clearly distinguish the "inner wall surface of the insertion hole 111" in this embodiment from the positional layout of other non-inner walls such as the "notch" and "groove wall of the limiting groove 112" in the prior art.

[0039] Based on this, the existence of the guide structure 3 allows the guide portion 22 to gradually correct its insertion posture during the insertion process of the plug connector into the socket connector, even if it is not fully aligned with the limiting groove 112. This is achieved by utilizing the geometric features of the guide structure 3, ultimately ensuring the alignment and engagement of the guide portion 22 with the limiting groove 112. This helps to avoid incorrect insertion direction or incomplete insertion, even in application environments where the connector installation location is invisible or difficult to access. In short, the guide structure 3 provides a progressive guiding and positioning path for the guide portion 22 of the plug connector at a structural level. This helps guide the plug connector in the correct insertion direction in the initial stage of insertion, thereby increasing the likelihood of successful insertion. It is particularly suitable for application environments where the connector installation location is invisible or difficult to access.

[0040] Furthermore, the "guide structure 3" can be a protrusion, bevel, guide rib, or other guiding shape feature on the inner wall surface of the insertion hole 111. Its position and angle can be flexibly set according to specific design requirements to achieve matching with the guide part 22 of the plug connector in shape or movement trajectory. Without limiting the specific form, this structure can improve the fault tolerance of the insertion operation to a certain extent, and enable a smoother and more directional insertion process even if the operator lacks visual or tactile feedback. Therefore, through the above structural design, this application can, to a certain extent, solve the problem in the prior art of insertion failure or reduced connection reliability caused by the connector being difficult to see or touch, and provide a beneficial technical solution for reliable docking of connector devices under complex working conditions.

[0041] In some embodiments, the plug portion 11 is rotatably mounted on the socket body 1. Specifically, the plug portion 11 can be connected to the socket body 1 via a rotating shaft, hinge mechanism, or other connection method that allows relative rotation, enabling the plug portion 11 to be angularly adjusted relative to the socket body 1 around its axis or a predetermined rotation axis. This structural design allows the plug portion 11 to have a certain degree of rotational freedom during the insertion of the plug connector. Even if the plug connector and the plug hole 111 are not fully aligned, the contact force during the insertion process can drive the plug portion 11 to make fine adjustments, thereby gradually aligning the guide portion 22 of the plug connector with the limiting groove 112. Since the plug portion 11 can rotate around the socket body 1 within a certain range, it is beneficial to achieve adaptive adjustment of the insertion direction in places where the connector installation position is not visible or difficult to access, thereby improving the success rate of insertion to a certain extent.

[0042] It is worth noting that "rotatable" should be understood as the plug portion 11 and the socket body 1 forming a rotatable assembly relationship. This assembly relationship can be either a rotational degree of freedom in a single direction or a swinging degree of freedom within a limited angle range, and the specific form can be selected according to the actual application requirements. Through the above structural arrangement, the alignment capability of the plug portion 11 under non-ideal insertion angles can be improved to a certain extent. Combined with the role of the guide structure 3, it helps the plug connector to be smoothly inserted into the socket connector even in the absence of vision or precise operation, thereby improving the problem of insufficient insertion accuracy and convenience of connectors in the prior art in environments where they are not visible or difficult to access.

[0043] In some examples, refer to Figure 3 and Figure 4The guide structure 3 in the socket connector has a guide surface 1131, which is disposed on the inner wall surface of the insertion hole 111 and faces the central area of ​​the insertion hole 111. The guide surface 1131 is used to slide and abut against the guide portion 22 on the plug connector during the insertion process. That is, when the plug connector is inserted into the insertion hole 111, a part of the outer surface of the guide portion 22 will contact the guide surface 1131 and slide along the guide surface 1131 under the drive of the insertion force. This sliding contact process allows the guide portion 22 to be gradually corrected in direction by means of the geometry of the guide surface 1131 when there is a slight deviation in the insertion direction, thereby tending to align with the limiting groove 112.

[0044] It is worth noting that the "guide surface 1131" can be a sloped surface, an arc-shaped surface, or other surface structures with a certain tilt angle or guiding tendency. Its surface finish, tilt angle, and arrangement direction can be matched and optimized according to the structural characteristics of the guide part 22 and the expected insertion path. By setting the guide surface 1131, a smooth guiding relationship is generated between the guide part 22 and the insertion hole 111 in the initial stage of insertion, which helps to reduce insertion resistance and enhance self-alignment capability. It is particularly suitable for working conditions where the connector installation position is not visible or difficult to access.

[0045] It is important to understand that "sliding contact" does not refer to the formation of a stable mechanical connection, but rather to a continuous, guiding surface contact behavior during the insertion process. This behavior is beneficial for improving the fault tolerance and directional adjustment capability of the insertion. Therefore, this embodiment, by specifying the design of the guiding surface 1131 of the guiding structure 3, provides a clear guiding path for the guiding part 22 structurally, enhancing the entire socket connector's ability to achieve effective alignment and insertion under non-ideal operating conditions. This can alleviate, to some extent, the technical problems caused by the high dependence on visual and tactile feedback in traditional connectors.

[0046] In some examples, the guide surface 1131 extends spirally from the open end of the insertion hole 111 to the inner bottom wall, reaching the limiting groove 112. Specifically, the guide surface 1131 starts from the open end of the insertion hole 111, extends spirally along the axial direction of the insertion hole 111 and around its central axis, and finally extends to the position of the limiting groove 112. This spirally extending guide surface 1131 can form continuous sliding contact with its guide portion 22 during the insertion of the plug connector, causing the guide portion 22 to be subjected to the lateral force of the guide surface 1131 during insertion, gradually rotating and moving along the spiral path. This allows the orientation of the guide portion 22 to be gradually adjusted during insertion and tend to align with the limiting groove 112. Through the above structural design, even if there is an angular or positional deviation during initial insertion, the plug connector can be guided to the correct insertion posture under the action of the spiral guide surface 1131.

[0047] It is worth noting that "spiral extension" should be understood as a three-dimensional guide path in which the guide surface 1131 extends both circumferentially and axially along the insertion hole 111. Its specific pitch, starting angle, and width can be designed to match the structure of the mating guide part 22. This type of structure can, to a certain extent, increase the guide length and alignment space during the insertion process, enhance the possibility of adaptive alignment between the 11 insertion parts, and facilitate efficient and smooth insertion operations in environments with limited vision and touch.

[0048] In some alternative implementations, such as Figure 3 and Figure 4 As shown, the guide surface 1131 has a first end 1131a, which is flush with the opening end of the insertion hole 111. Exemplarily, this first end 1131a is configured as the initial end of the guide surface 1131, which is the end that preferentially contacts the guide surface 1131 when the guide part 22 enters the insertion hole 111. Specifically, the starting position of the guide surface 1131 is set at the outermost edge of the insertion hole 111, at the same height or position as the opening edge of the insertion hole 111, so that when the guide part 22 of the plug connector just enters the insertion hole 111, it can immediately contact the guide surface 1131 and enter a sliding contact state under its action, thereby achieving the guiding function in the initial stage of insertion.

[0049] This arrangement improves the alignment efficiency of the guide 22 after it enters the socket 111 and reduces the risk of shaking or jamming during initial insertion. Simultaneously, having the first end 1131a of the guide surface 1131 flush with the opening of the socket 111 avoids damage such as bumps or peeling during use or transportation due to the guide surface 1131 protruding excessively, thus improving the durability and safety of the structure. Here, "flush" should be understood as meaning that the boundaries of the two surfaces are on the same plane or have virtually no significant difference in elevation, not that they must be absolutely identical. In summary, by setting the first end 1131a of the guide surface 1131 flush with the opening of the socket 111, the plug connector receives effective guidance during the initial insertion stage, helping the guide 22 to smoothly enter the socket 111 and perform self-alignment insertion along a set trajectory, improving the actual operability and connection reliability of the socket connector in locations with limited visibility or confined space.

[0050] In some embodiments, the guide surface 1131 further has a second end 1131b, which smoothly communicates with the limiting groove 112. Exemplarily, the second end 1131b is the end of the guide surface 1131, and is configured as a chamfered surface that smoothly communicates with the limiting groove 112, with a smooth surface and no protrusions. Specifically, the second end 1131b adopts a chamfered surface structure that smoothly transitions with the limiting groove 112, so that the guide portion 22 can naturally enter the limiting groove 112 after sliding past the end of the guide surface 1131.

[0051] It is worth noting that the "chamfered surface" refers to the transition surface between the guide surface 1131 and the limiting groove 112. Its surface is relatively smooth, without obvious protrusions or steps, thus ensuring a continuous sliding path without significant obstructions. Through this structural design, when the guide portion 22 of the plug connector slides along the guide surface 1131 during insertion, it can not only be smoothly guided to align with the limiting groove 112, but also smoothly enter the limiting groove 112 after sliding to the end position of the guide surface 1131, thereby achieving precise alignment and mating. Here, "smooth connection" should be understood as the geometric continuity between the guide surface 1131 and the limiting groove 112, without abrupt shape changes or steps, which is beneficial to the stability and smoothness of the guide portion 22 during the transition process. Simultaneously, the chamfered surface reduces edge stress concentration, which also helps extend the service life of the structure and reduce the risk of structural damage. In summary, by setting a chamfered surface between the second end 1131b and the limiting groove 112, the smoothness of the plug connector guide part 22 entering the limiting groove 112 and the rationality of the structural transition can be improved to a certain extent. This enhances the self-alignment connection effect of the connector device in environments with limited visibility or inconvenient installation, and alleviates the problem of difficult insertion caused by poor structural transition of traditional connectors.

[0052] In some embodiments, the limiting grooves 112 are provided on the outer peripheral wall of the insertion hole 111, and at least two are symmetrically provided, that is, at least two sets of limiting grooves 112 are distributed in the circumferential direction of the insertion hole 111, and are arranged facing each other. The guide surfaces 1131 correspond one-to-one with the limiting grooves 112, and the two guide surfaces 1131 corresponding to the two symmetrically provided limiting grooves 112 have opposite rotation directions. Exemplarily, the number of sets of guide parts 22 provided on the plug connector corresponds one-to-one with the limiting grooves 112. In order to further improve the alignment capability during the insertion process, the guide surfaces 1131 in the guide structure 3 are constructed as a spiral extension structure, which extends from the opening end of the insertion hole 111 toward the inner bottom wall, and specifically starts from the inlet end near one side of the limiting groove 112, and gradually spirals to the bottom end of the adjacent limiting groove 112. This guiding method creates a progressive attitude adjustment path after the guide part 22 is inserted into the guide surface 1131. This allows the plug connector to be guided along the guide surface 1131 by multiple guide parts 22 until it aligns with multiple limiting slots 112, even if the initial insertion direction is not perfectly aligned with the socket connector. This ensures effective insertion. Here, "symmetrical arrangement" refers to the limiting slots 112 being distributed relatively or equidistantly in the circumferential direction, while "spiral extension" represents the combined extension path of the guide surface 1131 in the axial and circumferential directions, facilitating progressive adjustment. "One-to-one correspondence" means that the number of guide parts 22 on the plug connector matches the number of limiting slots 112 on the socket connector. Each guide part 22 has a corresponding limiting slot 112, preventing interference or mismatch during insertion. This structural design can expand the directional tolerance of insertion to a certain extent, improve alignment efficiency and adaptability in blind insertion situations, and is particularly suitable for electrical connection environments where the human eye cannot see or where space is limited. It is beneficial for improving the operational convenience and stability of the connector device.

[0053] In some embodiments, the guide structure 3 and the insertion part 11 are integrally injection molded. For example, the guide structure 3 is integrally molded on the inner wall surface of the insertion part 11 during a one-time molding process. Specifically, the guide structure 3 is a structural component extending along the inner wall of the insertion hole 111 and having a guide surface 1131. It is attached to the insertion part 11 and configured to slide against the guide part 22 during the insertion of the plug connector, thereby achieving alignment between the plug connector and the limiting groove 112. Using integral injection molding avoids problems such as insufficient strength or positional deviation at the joint caused by traditional bonding, welding, or mechanical assembly processes. This improves the overall connection strength between the guide structure 3 and the insertion part 11, enhancing its structural stability against external forces or repeated friction during long-term use. Since the guide structure 3 needs to withstand the sliding friction of the guide part 22 during insertion, if it is formed by post-processing, the guiding accuracy may be affected by loosening or deformation. However, integral molding achieves better structural stability and consistency. Furthermore, the integrated injection molding process offers excellent repeatability and dimensional control during manufacturing, significantly reducing processing steps, lowering manufacturing costs, and improving production efficiency. In this embodiment, "integrated injection molding" refers to molding the connector 11 and its inner wall guide structure 3 as a single unit in a single molding process using an injection mold, rather than molding two parts separately and then assembling them. This avoids functional instability caused by assembly tolerances. Therefore, this design can improve the structural reliability of the product to a certain extent while reducing the complexity and cost of the manufacturing process, making it suitable for electrical connection scenarios with high requirements for connection reliability and processing efficiency.

[0054] In some embodiments, the width of the guide surface 1131 ranges from 0.3 mm to 1 mm. It is understood that the width of the guide surface 1131 is set within this range primarily based on a balance between guiding function and structural strength. On the one hand, if the guide surface 1131 is too wide, although it can contact the guide portion 22 on the plug connector over a larger area, which is beneficial for the guiding effect, it may occupy too much space inside the socket 111, which is not conducive to the overall compact layout of the connector. On the other hand, if the guide surface 1131 is too narrow, although it saves space, the contact area with the guide portion 22 during insertion is reduced, which may affect the guiding stability to some extent or cause the guide portion 22 to slip off. Therefore, limiting the width of the guide surface 1131 to between 0.3 mm and 1 mm helps to achieve a good guiding effect within a limited space, while not significantly affecting the overall structural design of the socket 111.

[0055] For example, the width of the guide surface 1131 ranges from 0.4 mm to 0.5 mm. It is understood that by controlling the width of the guide surface 1131 within the above range, while ensuring sufficient contact with the guide part, the risk of interference caused by excessive width can be reduced, and the problem of guidance instability caused by insufficient width can be avoided.

[0056] In some embodiments, the length of the guide structure 3 in the axial direction of the insertion portion 11 ranges from 5mm to 9mm. For example, the axial length of the guide structure 3 in the insertion portion 11 is the vertical distance between the two ends of the guide surface 1131 along the axial direction of the housing. The main purpose of setting this axial length is to improve the stability and continuity of the guiding engagement during the insertion of the plug connector guide portion 22 into the insertion hole 111, based on the guide structure 3 having sufficient contact travel. When the length of the guide structure 3 is short, the guide portion 22 may only contact the guide structure 3 for a short time, easily leading to unstable guiding effect; conversely, if the guide structure 3 is too long, it will increase the insertion resistance and also adversely affect the spatial layout of the insertion hole 111. Therefore, setting this length within the range of 5mm to 9mm is beneficial to satisfy the guiding function while also taking into account the smoothness of the insertion operation and the compactness of the structure. It should be noted that the "length of the guide structure 3 in the axial direction of the plug portion 11" refers to the extension dimension of the guide structure 3 along the central axis of the plug hole 111, and not its actual length after spiral path or surface unfolding. This range is also relatively easy to achieve in injection molding or other integral molding processes, which helps to achieve a reasonable balance between precision control and functional requirements, thereby improving the overall adaptability and practicality of the socket connector to a certain extent.

[0057] For example, the length of the guide structure 3 in the axial direction of the insertion portion 11 is configured to be 7 mm. It is understood that a length of 7 mm can provide sufficient guidance during the insertion process, so that the guide portion 22 can smoothly align with the guide structure 3 when entering the insertion hole 111, thereby achieving the self-aligning function.

[0058] In some examples, the width of the limiting groove 112 ranges from 2mm to 5mm. Understandably, if the groove width is too small, the guide part 22 may not be able to enter the limiting groove 112 smoothly, resulting in misalignment or jamming during the insertion process; while if the groove width is too large, it may not be able to effectively restrict the position of the guide part 22, thereby affecting the realization of the self-alignment function.

[0059] For example, the groove width of the limiting groove 112 is configured to be 3.8 mm. It can be understood that a groove width of 3.8 mm can effectively balance stability and fitting accuracy during the mating process, avoiding mating problems caused by groove widths that are too large or too small.
