Description

Technical Field

[0001] This invention relates to the field of electrical connector structure technology, and more specifically to a connector structure and its electronic device. Background Technology

[0002] Connectors, as crucial components in electrical equipment for transmitting electrical signals or power, are widely used in electronic devices, automobiles, communications, and industrial control. Existing connectors typically consist of an insulating body, terminal assemblies, and an external fixing structure. The terminal assembly usually includes a contact portion and a fixing portion in the insertion direction. The contact portion contacts the corresponding mating terminal to transmit electrical signals, while the fixing portion is embedded or pressed into the insulating body to achieve mechanical positioning and electrical connection.

[0003] In practical applications, connectors typically form an electrical connection through the mating of male and female terminals. However, existing male and female terminals are often limited by factors such as installation space, assembly force, and material properties in terms of mating structure and strength, making them prone to connection instability under long-term use or external environmental influences. When external vibrations, impacts, or temperature changes act on the connector, the mating interface between the male and female terminals may loosen or even separate, leading to unstable connection. Unstable connection not only causes signal transmission interruptions or increased contact resistance but may also trigger equipment malfunctions or short-circuit risks, seriously affecting system safety and reliability.

[0004] Therefore, how to improve the fit and stability between the male and female connectors and prevent them from loosening or separating under external forces, thereby improving the connection reliability and operational stability of the connector, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0021] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 This is a schematic diagram of the overall structure of the connector structure provided in an embodiment of the present invention; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 This is a cross-sectional view of the connector structure provided in an embodiment of the present invention; Figure 4 for Figure 3 Enlarged view of point B in the middle; Figure 5 for Figure 3 Enlarged view of point C in the middle; Figure 6 for Figure 3 Enlarged view of point D in the middle.

[0025] The connector structure provided in this embodiment is applied to scenarios requiring vibration and shock resistance while maintaining stable electrical connections in precision electronic devices. By improving the connector structure in this embodiment, reliable positioning and secure locking of the connector structure after insertion are achieved, thereby improving the stability of electrical transmission and conductivity reliability.

[0026] Please see Figures 1-6 The connector structure provided in this embodiment includes a first connecting body 001, a second connecting body 002, and a positioning component 003. The first connecting body 001 includes a male terminal housing 10, a male terminal signal piece 11, and a male terminal contact piece 12, with the male terminal signal piece 11 and the male terminal contact piece 12 disposed on the male terminal housing 10. The second connecting body 002 includes a female terminal housing 20, a female terminal signal piece 21, and a female terminal contact piece 22, with the female terminal signal piece 21 and the female terminal contact piece 22 disposed on the female terminal housing 20. The male terminal signal piece 11 is electrically connected to the female terminal signal piece 21, and the male terminal contact piece 12 is electrically connected to the female terminal. Contact piece 22 is electrically connected; positioning assembly 003 includes positioning post 30 and locking member 31. Positioning post 30 is disposed on male end housing 10, and locking member 31 is disposed on female end housing 20. Locking member 31 and positioning post 30 are rotatably engaged so that male end signal piece 11 and female end signal piece 21, and male end contact piece 12 and female end contact piece 22 are fixed in preset contact positions. The preset contact positions refer to the positions where male end signal piece 11 and female end signal piece 21 and male end contact piece 12 and female end contact piece 221 are in contact and overlap after the connector structure is assembled.

[0027] Specifically, the male terminal signal piece 11 and the male terminal contact piece 12 are both installed inside or on the surface of the male terminal housing 10. The male terminal housing 10 can be made of a plastic material with insulating properties or a metal shielded shell structure to support the internal conductive components and shield against electromagnetic interference. The male terminal signal piece 11 is mainly used to transmit low-current control signals and is usually made of copper alloy or gold-plated copper to reduce contact resistance during signal transmission and improve signal stability. The male terminal contact piece 12 is used to transmit main current or supply voltage. It can be made of a high-conductivity metal material and coated with an anti-oxidation coating to enhance corrosion resistance and conductivity reliability.

[0028] The female signal piece 21 and the female contact piece 22 are respectively disposed at the insertion end position inside the female housing 20 to achieve corresponding electrical connection with the male signal piece 11 and the male contact piece 12. The female housing 20 can also adopt a high-strength insulating plastic or metal shielding structure to prevent external mechanical impact or electromagnetic interference. The female signal piece 21 and the female contact piece 22 can be designed as an elastic slot structure or a spring-type clamping structure, respectively, to form continuous contact pressure on the male terminal during the insertion process, thereby ensuring the reliability of the connection and the continuity of the signal.

[0029] Regarding the structural connection, to ensure a stable fit between the male and female ends after insertion, this embodiment includes a positioning component 003 between them. Specifically, the positioning post 30 can be cylindrical or have a flanged limiting structure to provide guidance and a positional reference in the insertion direction. The locking member 31 can be a rotating ring structure or a slot-type locking structure, achieving mechanical limiting and fastening with the positioning post 30 through rotation or engagement. The rotational engagement between the locking member 31 and the positioning post 30 can be achieved through threaded connection, cam locking structure, or elastic snap-fit ​​structure, effectively preventing loosening after connection.

[0030] After the male and female connectors are inserted, the locking element 31 and positioning post 30 in the positioning assembly 003 achieve precise positioning and reliable locking through rotational engagement, ensuring stable contact between the male signal piece 11 and the female signal piece 21, and between the male contact piece 12 and the female contact piece 22, at predetermined positions. Because this locking mechanism provides additional axial clamping force after insertion, it significantly improves the continuous contact pressure between terminals, maintaining the stability of the conductive path even under external vibration, impact, or temperature changes. This avoids the contact problems or signal interruptions caused by mechanical clearance or thermal expansion and contraction in traditional plug-in connectors. Furthermore, this structure requires no additional fastening tools during assembly; rotational locking enables quick connection and disassembly, offering excellent reusability and ease of maintenance.

[0031] Furthermore, the female end housing 20 has recessed mounting grooves 40 on both sides, and the locking member 31 is rotatably installed in the mounting grooves 40. The bottom of the locking member 31 has a locking groove 311. The bottom of the positioning post 30 is fixed to the male end housing 10, and the top of the positioning post 30 is threadedly connected to the locking groove 311. Specifically, the female end housing 20 has recessed mounting grooves 40 on both sides to accommodate and support the locking member 31. The mounting groove 40 can be an annular groove 403 structure, with its opening facing the male end housing 10, to ensure that the locking member 31 has sufficient rotational space in the insertion direction. The bottom of the locking member 31 has a locking groove 311, which is a threaded groove structure that mates with the top of the positioning post 30. The bottom of the positioning post 30 is fixedly installed on the male end housing 10, and its top outer wall has a threaded section that matches the locking groove 311. The two are fastened by a threaded connection. The positioning post 30 can be a metal cylindrical structure, or it can be made into a structure with a limiting shoulder or anti-loosening flange according to design requirements to enhance the shock resistance after locking. As a common form of detachable mechanical connection, threaded connection can achieve repeated assembly and disassembly while ensuring connection strength, and the locking force can be precisely adjusted by controlling the rotation angle, thereby making the connection between the male end housing 10 and the female end housing 20 more stable.

[0032] After the male housing 10 is inserted into the female housing 20 and the corresponding signal pieces and contact pieces are in contact, the operator rotates the locking member 31, causing the locking groove 311 at its bottom to engage with the positioning post 30 along the thread direction and gradually tighten. With the locking action completed, the male housing 10 is axially pressed against the female housing 20, thereby forming stable mechanical and electrical contact between the male signal piece 11 and the female signal piece 21, and between the male contact piece 12 and the female contact piece 22. This threaded locking structure maintains high contact pressure even under external vibration, impact, or temperature changes, avoiding problems such as loosening, incomplete connection, or signal interruption that are common in traditional plug-in connections, significantly improving connection stability and electrical transmission reliability.

[0033] Furthermore, the mounting groove 40 includes a first groove 401 and a second groove 402, which are opposite to each other and pass through each other. The locking member 31 includes a gripping part 312, a connecting part 313, and a locking part 314. The gripping part 312 and the locking part 314 are respectively disposed at both ends of the connecting part 313. The locking part 314 is disposed in the second groove 402, and the locking groove 311 is disposed on the locking part 314. The gripping part 312 is disposed on the side of the first groove 401 away from the second groove 402. Specifically, the gripping part 312 is disposed at one end of the connecting part 313, and its shape can be cylindrical, T-shaped, or a knob-type structure with anti-slip texture, allowing the operator to lock or unlock by rotating. The gripping part 312 is disposed within the first slot 401 and located on the side away from the second slot 402, i.e., on the outer side of the female end housing 20, thus facilitating manual gripping and operation. The connecting part 313 is the intermediate transition part of the locking member 31, used to connect the gripping part 312 and the locking part 314. It can adopt a rod-shaped or short shaft structure and has sufficient mechanical strength to withstand the torque force during tightening. The locking part 314 is disposed at the other end of the connecting part 313, correspondingly installed within the second slot 402, and threadedly engaged with the positioning post 30 on the male end housing 10. The locking groove 311 is formed on the locking part 314 and is used to engage with the external thread section at the top of the positioning post 30 to achieve locking between the two. The locking groove 311 can be designed as a standard thread groove or an anti-loosening thread groove with a self-locking angle to improve the stability after connection and prevent loosening in a vibration environment. The above-mentioned thread structure is well known to those skilled in the art. Its form can be selected as fine thread, trapezoidal thread or anti-loosening thread according to specific application requirements, so it will not be described in detail in this embodiment.

[0034] When the first connecting body 001 and the second connecting body 002 are inserted, the operator can rotate the gripping part 312 to drive the locking part 31 to rotate as a whole, so that the locking groove 311 on the locking part 314 gradually engages with the positioning post 30 along the thread direction. As the tightening action is performed, the locking part 31 axially presses the male end housing 10 towards the female end housing 20, so that a stable and continuous contact pressure is formed between the male end signal piece 11 and the female end signal piece 21, and between the male end contact piece 12 and the female end contact piece 22. The threaded locking method operated by the gripping part 312 not only improves the assembly efficiency, but also effectively prevents the loosening problem that is easy to occur in traditional snap-fit ​​or plug-in structures.

[0035] Furthermore, the locking member 31 also includes an elastic member 315. One end of the elastic member 315 is connected to the top surface of the second slot 402, and the other end is connected to the top surface of the locking part 314. Specifically, one end of the elastic member 315 is fixedly connected to the top surface of the second slot 402, and the other end is connected to the top surface of the locking part 314, thereby forming an axially compressible elastic connection structure. The elastic member 315 can be a spiral compression spring, a wave spring, or a rubber buffer pad, etc., to provide controllable elastic force and recovery characteristics. When the operator needs to connect the first connecting body 001 and the second connecting body 002, the operator can manually pull up the grip 312 to move the locking member 31 axially upward, thereby compressing the elastic member 315. In this state, by rotating the grip 312, the locking member 31 is rotated, causing the locking groove 311 on the locking part 314 to engage with the positioning pin 30 on the male end housing 10 and gradually tighten. After the locking operation is completed, the operator releases the grip 312. Under the restoring force of the elastic element 315, the locking element 31 automatically returns to its original position, so that the grip 312 abuts against the outer surface of the female end housing 20, forming an axial pre-tightened state.

[0036] The pre-tightening force provided by the elastic element 315 effectively restricts the free rotation of the locking element 31 after locking, preventing loosening caused by slight rotation of the locking element 31 due to external vibration, impact, or temperature changes. Under the action of the elastic element 315, the gripping part 312 remains in contact with the female end housing 20, thus forming a reliable anti-loosening self-locking effect and ensuring that the connection structure maintains a stable mechanical connection force over a long period. Furthermore, the elastic element 315 also provides a buffering and energy absorption function under external forces. When the connector is subjected to impact or vibration loads, the elastic element 315 absorbs and disperses some energy, reducing the instantaneous stress acting between the first connecting body 001 and the second connecting body 002, avoiding problems such as housing cracking or loose terminal contact due to excessive rigidity, thereby improving the impact resistance and fatigue resistance of the entire connector structure.

[0037] Furthermore, an annular groove 403 is formed within the first slot 401, and a rolling element 404 is rotatably mounted within the annular groove 403. The outer wall of the rolling element 404 abuts against the outer wall of the connecting portion 313. Specifically, the rolling element 404 can be in the form of balls, rollers, or wheels, and its outer wall contacts the outer wall of the connecting portion 313, so that the locking element 31 can generate rolling friction rather than sliding friction during rotation, thereby significantly reducing rotational resistance. The above-mentioned rolling element 404 structure is a support or guide component well known to those skilled in the art, and can be made of materials such as metal, stainless steel, and engineering plastics to meet different usage environment requirements, so it will not be described in detail in this embodiment.

[0038] In practical implementation, when the operator performs locking or unlocking operations through the grip 312, the connecting part 313 of the locking member 31 rotates relative to the annular groove 403 in the female end housing 20. At this time, the rolling member 404 rolls synchronously with the outer wall of the connecting part 313 in the annular groove 403, ensuring that the rotation axis of the locking member 31 always remains on the designed center line. This effectively improves the axial accuracy during rotation and avoids problems such as jamming, shaking, or wear of the locking member 31 due to eccentricity or uneven friction. The annular groove 403 not only provides rotation space for the rolling member 404 but also provides guiding constraints on the rotation path of the locking member 31, making the locking action smoother and more stable.

[0039] Furthermore, the female signal chip 21 includes a first signal terminal 211 and a second signal terminal 212. The first signal terminal 211 includes a first vertical portion 2111 and a first bent portion 2112. The second signal terminal 212 includes a second vertical portion 2121 and a second bent portion 2122. The distance between the first bent portion 2112 and the second bent portion 2122 is less than the distance between the first vertical portion 2111 and the second vertical portion 2121. A first insertion chamber 2123 is formed between the first bent portion 2112 and the second bent portion 2122. The male signal chip 11 is inserted into the first insertion chamber 212. 3. The female contact piece 22 includes a first electrical terminal 221 and a second electrical terminal 222. The first electrical terminal 221 includes a third vertical portion 2211 and a third bent portion 2212. The second electrical terminal 222 includes a fourth vertical portion 2221 and a fourth bent portion 2222. The distance between the third bent portion 2212 and the fourth bent portion 2222 is less than the distance between the third vertical portion 2211 and the fourth vertical portion 2221. A second insertion chamber 2223 is formed between the third bent portion 2212 and the fourth bent portion 2222. The male contact piece 12 is inserted into the second insertion chamber 2223.

[0040] Specifically, the first bent portion 2112 and the second bent portion 2122 are arranged opposite to each other, and the distance between them is smaller than the distance between the first vertical portion 2111 and the second vertical portion 2121, so that the two bent portions together form a narrow space, which constitutes the first insertion chamber 2123. The first insertion chamber 2123 is used to accommodate the male terminal signal piece 11. When the male terminal signal piece 11 is inserted, the two bent portions generate a clamping force on the male terminal signal piece 11 due to their elastic deformation, thereby achieving a stable contact fit. The distance between the third bent portion 2212 and the fourth bent portion 2222 is smaller than the distance between the third vertical portion 2211 and the fourth vertical portion 2221, and the two bent portions form a second insertion chamber 2223, which is used to insert the male terminal contact piece 12. When the male contact piece 12 is inserted into the second insertion chamber 2223, the third bending portion 2212 and the fourth bending portion 2222 clamp the male contact piece 12 under the action of elastic restoring force, thereby achieving stable electrical contact and mechanical fixation.

[0041] In practical implementation, when the first connecting body 001 and the second connecting body 002 are inserted, the male signal piece 11 is guided into the first insertion chamber 2123. The first bending portion 2112 and the second bending portion 2122 apply clamping force to the male signal piece 11, ensuring that it can maintain tight contact under micro-vibration or temperature change conditions, preventing poor contact or increased resistance. Similarly, when the male contact piece 12 is inserted into the second insertion chamber 2223, the third bending portion 2212 and the fourth bending portion 2222 form a bidirectional clamping force on it, making the contact surface uniformly stressed, thereby improving the stability of the conductive path. Through this double-bending clamping structure, the insertion force between the male and female ends is moderate, the contact area is large, and the elastic recovery performance is good, effectively avoiding the problems of arcing, loosening, or contact fatigue caused by uneven force in traditional single-contact structures.

[0042] Furthermore, the male terminal signal piece 11 is provided with a first guide portion 111 at its top. The width of the first guide portion 111 gradually increases and then gradually decreases from top to bottom along the first direction. The first guide portion 111 is shaped to fit the first insertion chamber 2123. The male terminal contact piece 12 is provided with a second guide portion 121 at its top. The width of the second guide portion 121 gradually increases and then gradually decreases from top to bottom along the first direction. The second guide portion 121 is shaped to fit the second insertion chamber 2223. Specifically, the width of the first guide portion 111 gradually increases and then decreases from top to bottom along the first direction, forming a streamlined outline. This structure is used to guide the male terminal signal piece 11 during insertion into the first insertion chamber 2123 of the female terminal signal piece 21, so that the male terminal signal piece 11 can smoothly enter the insertion chamber and avoid collisions, jamming, or misalignment caused by initial deviation or improper operating angle. The specific shape of the first guide portion 111 can be designed according to the cross-section of the insertion chamber. The above design method is commonly used by those skilled in the art, so it will not be described in detail in this embodiment.

[0043] After insertion, the first guide portion 111 matches the shape of the first insertion chamber 2123, forming a limiting space in the lateral and longitudinal directions. This prevents the male signal piece 11 from being accidentally pulled out or displaced from the first insertion chamber 2123, thus acting as a stop and ensuring that the signal terminal maintains stable contact pressure and reliable electrical connection during use. Similarly, the second guide portion 121 at the top of the male contact piece 12 has a width that first increases and then decreases along the first direction, matching the shape of the second insertion chamber 2223 formed by the female contact piece 22. During the insertion of the male contact piece 12 into the second insertion chamber 2223, the second guide portion 121 also acts as a guide, allowing the male contact piece 12 to be smoothly positioned within the insertion chamber, reducing insertion resistance and the risk of misalignment. After the insertion is completed, the second guide part 121 cooperates with the second insertion chamber 2223 to form a limiting effect, preventing the male contact piece 12 from coming out of the second insertion chamber 2223 under the action of external force, maintaining the continuous contact force of the contact terminal, and improving the stability of electrical transmission.

[0044] Furthermore, a recessed groove 50 is also provided on the female end housing 20. The recessed groove 50 is located on the top surface of the first slot 401 and matches the shape of the gripping part 312, which is engaged within the recessed groove 50. Specifically, the recessed groove 50 is located on the top surface of the first slot 401 and matches the shape of the gripping part 312. The gripping part 312 is engaged within the recessed groove 50, achieving dual axial and radial limiting. The recessed groove 50 can be a circular groove, a square groove, or an annular groove structure with curved bevels. Its size matches the outer diameter of the gripping part 312 to form a snug, embedded state after locking. This recessed groove 50 structure can be manufactured using processes such as injection molding, CNC milling, or mold forming. The specific processing method can be determined by those skilled in the art based on the housing material and manufacturing process, so it will not be described in detail in this embodiment.

[0045] In practical use, the operator first inserts the positioning pin 30 into the locking groove 311, and makes initial contact between the male signal piece 11 and the female signal piece 21, and between the male contact piece 12 and the female contact piece 22. Then, the operator pulls up the gripping part 312, causing the locking member 31 to move upwards axially. At this time, the elastic member 315 is compressed. In this state, the operator rotates the gripping part 312, causing the locking member 31 to rotate, so that the locking groove 311 on the locking part 314 engages with the threaded positioning pin 30 on the male housing 10 and gradually tightens, completing the locking process. After the locking action is completed, the operator releases the gripping part 312. Under the restoring force of the elastic member 315, the locking member 31 returns to its downward position, and the gripping part 312 automatically presses down and embeds into the recess 50 under the action of the elastic member 315, achieving snap-fit ​​positioning. At this time, the fitting structure between the groove 50 and the gripping part 312 can effectively limit the rotation and slight sway of the gripping part 312, thereby preventing the locking part 31 from deflecting due to external vibration or impact, ensuring the connection stability between the first connecting body 001 and the second connecting body 002, and thus ensuring the connection stability of the connector structure.

[0046] Furthermore, an auxiliary groove 60 is provided on the female end housing 20, which communicates with the recessed groove 50 and is used to assist the operator in grasping the gripping part 312. Specifically, the auxiliary groove 60 is a recessed structure provided on the side of the recessed groove 50, which provides the operator with an operating space that can accommodate fingers or tools when the gripping part 312 is partially embedded in the recessed groove 50, thereby realizing convenient lifting and rotation of the gripping part 312. The auxiliary groove 60 can adopt a strip groove, arc groove, or trapezoidal groove structure, and the groove depth and width can be adjusted according to the usage scenario to adapt to different specifications of locking parts 31 or operating methods. The above-mentioned groove structure is a conventional processing form well known to those skilled in the art, and can be realized by injection molding, CNC cutting, or molding processes, so it will not be described in detail in this embodiment.

[0047] In practical implementation, when a connection operation is required, the operator can insert their fingers or other grasping tools through the auxiliary groove 60 to easily grasp the gripping part 312 and pull it upwards. This compresses the elastic element 315 inside the locking member 31, causing the locking member 31 to disengage from the limiting state of the recess 50, facilitating rotation. After locking is complete, the gripping part 312 is released, and the locking member 31 returns to its original position under the elastic force of the elastic element 315. The gripping part 312 then re-embeds into the recess 50, achieving stable locking. Due to the interconnected design of the auxiliary groove 60 and the recess 50, adequate operating space is still provided even when the locking member 31 is within the recess 50, avoiding grasping difficulties caused by space constraints and improving operational convenience and flexibility.

[0048] An electronic device comprising any of the connector structures described above.

[0049] In summary, the connector structure provided in this embodiment achieves reliable positioning and secure locking of the connector structure after insertion, thereby improving the stability of electrical transmission and the reliability of electrical conductivity.
