[0003] From the perspective of structural composition, electrical connectors usually adopt a paired design of male and female ends, and realize flexible connection and disconnection of circuits through precise plugging and separation operations of the two. Its basic structure covers four core parts: contacts, insulators, bases and accessories. Among them, contacts are the core components for completing electrical connections and can be divided into positive contacts and negative contacts. In actual applications, the two establish a stable electrical connection channel through high-precision plugging actions; the main function of the insulator is to effectively isolate the contacts to prevent short circuit failures caused by accidental conduction between the contacts; the base not only provides reliable mechanical support for the internal structure of the electrical connector, but also has a protective function; accessories include crimping terminals and dust covers for fixing cables. Although these accessories may seem small, they play an indispensable role in improving the convenience and reliability of electrical connectors.
[0004] Although electrical connectors are widely used in the field of electrical connections, there are also some problems in actual use: in complex and changing usage environments, it is difficult to fully ensure the tight connection between the male and female ends of the electrical connector.

[0039] like Figures 1 to 10As shown, the waterproof and dustproof electrical connector provided by one embodiment of the present invention is configured to be able to connect a first cable 5 and a second cable 6, and is provided to include a male end 1 and a female end 2 that can be plugged into each other; a plurality of conductive terminals 101 are parallelly inserted on the male end 1, and the plurality of conductive terminals 101 are arranged along the circumferential direction; an adjusting ring 102 is commonly sleeved on all the conductive terminals 101, and the adjusting ring 102 is a corrugated structure and has elasticity, and can drive the conductive terminals 101 to swing outward when deformed; a mounting disk 103 is detachably provided on the male end 1, and the mounting disk 103 is an I-shaped structure with the large end outside, and a limiting ring 104 is coaxially provided on the inner end surface of the large end of the mounting disk 103; a push ring 105 is coaxially provided on the outer end surface of the small end of the mounting disk 103, and the push ring 105 has plasticity. The cross-sectional shape of 105 is L-shaped, and the push ring 105 and the adjustment ring 102 form a stop fit; an annular installation area is formed between the push ring 105, the limit ring 104 and the mounting plate 103, and a plurality of balls 106 are inserted in the installation area along the circumferential direction, and the balls 106 simultaneously form a stop fit with the limit ring 104 and the push ring 105; a plurality of conductive sleeves 201 are inserted in parallel in the female end 2, and the plurality of conductive sleeves 201 are arranged along the circumferential direction, and the conductive sleeves 201 are sleeved on the conductive terminal 101 and electrically connected to the conductive terminal 101; a plurality of plug-in parts 202 are provided on the female end 2, and the plurality of plug-in parts 202 are evenly arranged along the circumferential direction, and pass through the mounting plate 103, and are inserted in the installation area, and the plug-in part 202 is located on the inner side of the ball 106 and forms a stop fit with the ball 106.
[0040] Specifically, in this embodiment, the male terminal 1 includes a first housing 107. A first base 108 is fixedly mounted within the first housing 107. During installation, the conductive terminal 101 has its inner end inserted into the first base 108 and its outer end positioned outside the first base 108. The conductive terminal 101 extends parallel to the axis of the first base 108. Multiple conductive terminals 101 are evenly arranged circumferentially about the axis of the first base 108 and are configured to form an electrical connection with the first cable 5.
[0041] The female end 2 includes a second housing 203. A second base column 204 is fixedly mounted within the second housing 203. The axes of the second base column 204 and the first base column 108 coincide during installation. To facilitate installation of the conductive sleeve 201, a plurality of first mounting holes 2041 are defined on the outer end surface of the second base column 204. These first mounting holes 2041 are evenly spaced circumferentially about the axis of the second base column 204. A conductive sleeve 201 is mounted within each first mounting hole 2041, and the conductive sleeve 201 is configured to form an electrical connection with the second cable 6. During installation, the mounting plate 103 is coaxially arranged on the outer end surface of the first base column 108 and is detachably connected to the first base column 108 via screws. To facilitate the passage of the conductive terminal 101, a plurality of second mounting holes 1031 are provided through the large end surface of the mounting plate 103. The plurality of second mounting holes 1031 are evenly arranged circumferentially about the axis of the mounting plate 103, and the aperture of the second mounting holes 1031 is larger than the diameter of the conductive terminal 101 to avoid interference when the adjusting ring 102 drives the conductive terminal 101 to swing outward. To facilitate the passage of the plug-in portion 202, a plurality of third mounting holes 1032 are provided through the large end surface of the mounting plate 103. The plurality of third mounting holes 1032 are evenly arranged circumferentially about the axis of the mounting plate 103. To achieve waterproof and dustproof functions, the end surfaces of the first base column 108 and the second base column 204 can be arranged to abut each other, and sealing rings can be inserted and sealed at the end surfaces.
[0042] The limiting ring 104 and the pushing ring 105 are arranged opposite each other, and an annular opening is formed between them. The width of the opening is smaller than the diameter of the ball 106, ensuring that the ball 106 will not escape from the installation area through the opening. The plug-in portion 202 is composed of a cylindrical first part and a spherical second part, wherein the first part is vertically arranged on the outer end face of the second base column 204, and the second part is fixedly arranged on the end of the first part, and the center of the second part and the axis of the first part are arranged to coincide. When in use, the second part can form a stop fit with the ball 106. To facilitate the passage of the conductive terminal 101, a plurality of fourth mounting holes 1021 are provided through the annular surface of the adjustment ring 102. The plurality of fourth mounting holes 1021 are evenly arranged along the circumference with respect to the axis of the adjustment ring 102. The diameter of the circle formed by the multiple plug-in parts 202 is smaller than the diameter of the circle formed by the multiple balls 106, ensuring that when the plug-in parts 202 and the balls 106 abut against each other, as the plug-in parts 202 move, the plug-in parts 202 can drive the balls 106 to move outward through the stop cooperation between them and the balls 106.
[0043] During the insertion of the male end 1 and the female end 2 , as the male end 1 and the female end 2 gradually approach each other, the plug-in portion 202 is first inserted into the installation area through the third installation hole 1032 , and then forms a stop fit with the ball 106 .
[0044] As the plug-in portion 202 continues to advance, its spherical second portion contacts the ball 106 and exerts a radial thrust, causing the ball 106 to move outward. Based on the principle of force transmission, the ball 106 transmits this force to the L-shaped push ring 105. Because the push ring 105 is made of a material with excellent plastic deformation properties (such as engineering plastic), under the compressive action of the ball 106, the push ring 105 gradually undergoes plastic deformation, evolving from its initial annular structure to a conical shape. During this process, the inner conical surface of the push ring 105 contacts the adjustment ring 102 closely, generating an axial compressive force that causes the adjustment ring 102 to undergo elastic deformation.
[0045] When the adjusting ring 102 is subjected to axial compression, the geometric changes in its corrugated folds are converted into radial expansion force, thereby driving the multiple conductive terminals 101 mounted thereon to swing radially outward, so that the contact area between the conductive terminals 101 and the conductive sleeve 201 is significantly increased. On the one hand, by increasing the mechanical engagement points, the mechanical connection between the two is strengthened; on the other hand, the closer physical contact effectively reduces the contact resistance, significantly improves the electrical connection performance, and ensures the stability of signal transmission and the high efficiency of power conduction.
[0046] When the second part of the plug-in part 202 passes the center position of the ball 106, the adjusting ring 102 begins to release the stored elastic potential energy and partially resets by relying on the resilience of its own elastic material; the reset movement of the adjusting ring 102 drives the pushing ring 105 to retract to the initial position through the mechanical linkage relationship between the pushing ring 105 and the ball 106, and at the same time makes the ball 106 move toward the axial direction along the installation area; finally, the ball 106 and the plug-in part 2 form a two-way clamping state to achieve self-locking, and through the combination of the point contact constraint of the ball 106 and the surface contact constraint of the pushing ring 105, a multi-dimensional mechanical locking between the male end 1 and the female end 2 is achieved, which effectively resists the influence of external environmental factors such as vibration and impact on the connection structure, and ensures the stable connection and reliable operation of the electrical connector under complex working conditions.
[0047] In a further embodiment, the push ring 105 is a conical structure, and the expansion opening is directed toward the adjustment ring 102 .
[0048] During use, when the plug-in part 202 pushes the ball 106 to move outward, the contact point between the ball 106 and the inner wall of the push ring 105 changes accordingly; based on the principle of force decomposition, the force exerted by the ball 106 on the push ring 105 can be decomposed into axial pressure and radial contraction force. Under the synergistic action of these two forces, the conical expansion area of the push ring 105 produces local plastic deformation, among which the part close to the contact point of the ball 106 shrinks inward first, forming a "dynamic shrinking effect". This shrinkage change is not evenly distributed, but presents a gradient change according to the movement trajectory of the ball 106 and the magnitude of the force. The closer the area is to the ball 106, the greater the shrinkage degree, thereby forming a gradually narrowing deformation area.
[0049] The generation of this deformation area significantly enhances the compression effect on the adjustment ring 102: on the one hand, the narrowed flare increases the contact pressure with the adjustment ring 102, so that the adjustment ring 102 bears a greater compression load under the same displacement, thereby producing more significant elastic deformation; on the other hand, the shape change of the shrinkage of the push ring 105 forms a geometric adaptation with the corrugated structure of the adjustment ring 102. While the contact area between the two is increased, it can also guide the adjustment ring 102 to deform in a predetermined direction, ensuring that the conductive terminal 101 swings outward at the optimal angle, thereby achieving a tighter mechanical bite and electrical connection with the conductive sleeve 201.
[0050] In addition, the conical structure of the push ring 105 also has a self-resetting guide function. During the elastic recovery stage of the adjustment ring 102, its gradually narrowing inner wall can provide a precise reset guide path for the ball 106, helping the ball 106 to return to its position smoothly and complete the locking process of the male end 1 and the female end 2.
[0051] In other embodiments, in order to further improve the connection strength between the male end 1 and the female end 2, the electrical connector configured to be waterproof and dustproof further includes a connecting component 3, which is configured to be able to connect the male end 1 and the female end 2.
[0052] In a further embodiment, the connecting assembly 3 is configured to include a threaded sleeve 301 and a threaded sleeve 302. The threaded sleeve 301 is sleeved on the female end 2 and can rotate around its own axis and move along its own axis, and form a stop fit with the female end 2; the threaded sleeve 302 is sleeved on the male end 1 and is threadedly inserted into the threaded sleeve 301.
[0053] Specifically in this embodiment, the threaded sleeve 301 is sleeved onto the second housing 203 during installation. To achieve a stop fit between the threaded sleeve 301 and the female end 2, a first annular platform 2031 is provided on the outer peripheral wall of the end of the second housing 203 facing the male end 1, and a second annular platform 3012 is provided on the inner peripheral wall of the end of the threaded sleeve 301 facing away from the male end 1. The second annular platform 3012 is slidably sleeved onto the second housing 203 during installation and can abut against the end face of the first annular platform 2031 to form a stop fit between the threaded sleeve 301 and the female end 2. The threaded sleeve 302 is coaxially arranged with the first base column 108 and sleeved onto the outside of the first base column 108. At this time, the first housing 107, the second housing 203, the threaded sleeve 301, and the threaded sleeve 302 surround and form a sealed chamber, thereby achieving waterproof and dustproof properties.
[0054] During use, after the plug-in part 202 is clamped by the ball 106, the threaded sleeve 301 is rotated so that the threaded sleeve 301 is threadedly sleeved on the threaded sleeve 302 until the first ring platform 2031 and the second ring platform 3012 form a stop fit, thereby improving the connection strength between the male end 1 and the female end 2 through the threaded fit between the threaded sleeve 301 and the threaded sleeve 302.
[0055] In a further embodiment, in order to facilitate maintenance of the conductive terminal 101 , the thread protector 302 and the male end 1 are configured to form a threaded fit.
[0056] Specifically in this embodiment, a mounting ring 1071 is provided on the end surface of the first housing 107 facing the female end 2 . The mounting ring 1071 is sleeved on the outside of the first base column 108 . The threaded sleeve 302 is threadedly sleeved on the mounting ring 1071 during installation.
[0057] During use, when the conductive terminal 101 needs to be maintained, the threaded sleeve 302 can be removed from the mounting ring 1071 to expose the conductive terminal 101 for easy operation.
[0058] In other embodiments, in electrical connection systems, foolproofing is crucial to prevent problems such as incorrect connection, short circuits, and even device damage caused by mis-insertion. To achieve effective foolproofing, the waterproof and dustproof electrical connector further includes a foolproofing component configured to ensure proper connection between the conductive terminal 101 and the conductive sleeve 201.
[0059] Specifically in this embodiment, the provision of the foolproof component can ensure that the conductive terminal 101 and the conductive sleeve 201 are accurately connected, thereby significantly improving the reliability and stability of the connection.
[0060] In a further embodiment, the foolproof component is configured to include a guide groove 401 and a guide platform 402, wherein the guide groove 401 is provided on the female end 2; the guide platform 402 is provided on the inner circumferential wall of the threaded sleeve 302, and the guide platform 402 is inserted into the guide groove 401.
[0061] Specifically in this embodiment, the guide platform 402 is an arc-shaped strip structure and extends in a direction parallel to the axis of the thread protector 302. The guide groove 401 is an arc-shaped strip structure and is provided on the circumferential side wall of the second base column 204 and extends in a direction parallel to the axis of the second base column 204.
[0062] During actual use, the alignment of the guide platform 402 and the guide groove 401 becomes a key condition for the smooth insertion of the male end 1 and the female end 2. Only when the guide platform 402 and the guide groove 401 are precisely aligned, can the male end 1 be smoothly inserted into the female end 2, and the insertion operation of the two can be realized. At this time, due to the precise positioning function of the anti-foolproof component, the conductive terminal 101 and the conductive sleeve 201 will be connected according to the pre-set corresponding relationship, that is, a matching connection is realized. This matching connection method can effectively avoid connection errors caused by mis-insertion, ensure that each conductive terminal 101 can establish a stable and reliable electrical connection with the corresponding conductive sleeve 201, thereby improving the connection performance and working efficiency of the electrical connector, while also reducing the safety hazards caused by connection errors and ensuring the stable operation of the entire electrical system.
[0063] In other embodiments, in order to prevent hand slipping, anti-slip grooves 3011 are provided on the outer peripheral wall of the threaded sleeve 301 .
[0064] In a further embodiment, the anti-slip pattern 3011 is a mesh structure.
[0065] Specifically, in this embodiment, the mesh structure is composed of crisscrossing lines. Compared to single-directional stripes or dot patterns, it can contact the operator's hand in multiple dimensions, significantly increasing the contact area. When the operator grasps the threaded sleeve 301, multiple tiny engagement points are formed between the hand skin and the meshed anti-slip lines 3011. These engagement points interact with each other when gripping force is applied, generating greater static friction, effectively preventing the hand from slipping relative to the threaded sleeve 301.
[0066] In addition, the structure of the mesh anti-slip pattern 3011 also has good stress dispersion characteristics: during the gripping process, the pressure applied by the hand can be evenly dispersed to the surface of the threaded sleeve 301 through the mesh pattern, avoiding the discomfort caused by local pressure concentration, while reducing the wear caused by long-term use and extending the effective service life of the anti-slip pattern 3011.
[0067] In other embodiments, the adjustment ring 102 is made of plastic.
[0068] Specifically in this embodiment, during the insertion of the male terminal 1 and the female terminal 2, the adjustment ring 102 must withstand the compression of the push ring 105 and drive the conductive terminal 101 to swing. The plastic material, with its elastic deformation ability, can produce controllable displacement when subjected to force, ensuring close contact between the conductive terminal 101 and the conductive sleeve 201. Taking common thermoplastic elastomers (TPE) or thermoplastic polyurethanes (TPU) as an example, these plastics combine the elasticity of rubber with the processing properties of plastics. Their elastic modulus and hardness can be adjusted through formulation to meet the deformation requirements of the adjustment ring 102 under different working conditions.
[0069] Furthermore, the plastic material exhibits excellent insulation properties, effectively preventing unintended electrical conduction between the adjustment ring 102 and the conductive terminal 101, thereby ensuring the electrical safety of the electrical connector. Furthermore, plastic exhibits excellent chemical stability, withstanding corrosion from various environmental factors, such as moisture and corrosive gases. This ensures that the adjustment ring 102 maintains structural integrity and stable performance even in complex environments. From a cost perspective, plastic is relatively inexpensive compared to metal, and the processing consumes less energy, helping to reduce the overall production cost of the electrical connector.
[0070] In other embodiments, in order to improve the connection strength between the conductive terminal 101 and the conductive sleeve 201, the conductive sleeve 201 is configured to include two conductive arc pieces 2011, the conductive arc pieces 2011 are elastic, and under the action of elasticity, the two conductive arc pieces 2011 tend to approach each other.
[0071] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0072] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
