[0001] The present invention relates to the technical field of connectors, and particularly to a waterproof and dustproof electrical connector. Background Art

[0002] An electrical connector is an electrical component that connects two or more circuits together, mainly used for circuit connections between cable lines and cable lines, and between cable lines and devices in electrical and electronic equipment, to achieve the transmission of low-frequency signals, high-frequency signals, and electrical energy, playing a crucial bridging role in the circuit.

[0003] From the perspective of structural composition, electrical connectors usually adopt a mating design of a male end and a female end. Through precise insertion and separation operations of the two, flexible connection and disconnection of the circuit are achieved. Its basic structure includes four core parts: contact components, insulators, bases, and accessories. Among them, the contact component, as the core component for completing electrical connection, can be divided into male contact components and female contact components. In actual applications, the two establish a stable electrical connection channel through high-precision insertion actions; the main function of the insulator is to effectively isolate the contact components to prevent short-circuit faults caused by accidental conduction between the contact components; the base not only provides reliable mechanical support for the internal structure of the electrical connector but also has a protective function; accessories include crimp terminals for fixing cables, dust caps, etc. Although these accessories seem insignificant, they play an indispensable role in improving the usability and reliability of electrical connectors.

[0004] Although electrical connectors are widely used in the field of electrical connection, there are still some problems in actual use: in a complex and changeable use environment, it is difficult to fully ensure the tight connection between the male end and the female end of the electrical connector.

[0009] Further, the connecting component comprises a threaded sleeve and a threaded protective cylinder, the threaded sleeve is sleeved on the female end and can rotate around its own axis and move along its own axis direction, and forms a stop fit with the female end; the threaded protective cylinder is sleeved on the male end and is threadedly inserted in the threaded sleeve.

[0010] Further, the threaded protective cylinder and the male end form a threaded fit.

[0011] Further, the waterproof and dustproof electrical connector further comprises an anti-misalignment component configured to enable the conductive terminals and the conductive sleeves to be connected in a one-to-one correspondence.

[0022] As Figures 1 to 10 shown, a waterproof and dustproof electrical connector provided by an 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 inserted into each other; a plurality of conductive terminals 101 are inserted in parallel on the male end 1, and the plurality of conductive terminals 101 are arranged circumferentially; an adjusting ring 102 is sleeved on all the conductive terminals 101 together, the adjusting ring 102 is of a corrugated structure and has elasticity, and can drive the conductive terminals 101 to swing outwards when deformed; a mounting disc 103 is detachably arranged on the male end 1, the mounting disc 103 is of an I-shaped structure with the large end on the outside, and a limiting ring 104 is coaxially arranged on the inner end surface of the large end of the mounting disc 103; a pushing ring 105 is coaxially arranged on the outer end surface of the small end of the mounting disc 103, the pushing ring 105 has plasticity, the cross-sectional shape of the pushing ring 105 is L-shaped, and the pushing ring 105 and the adjusting ring 102 form a stop fit; an annular mounting area is formed between the pushing ring 105, the limiting ring 104 and the mounting disc 103, and a plurality of balls 106 are inserted circumferentially in the mounting area, and the balls 106 simultaneously form a stop fit with the limiting ring 104 and the pushing ring 105; a plurality of conductive sleeves 201 are inserted in parallel in the female end 2, the plurality of conductive sleeves 201 are arranged circumferentially, the conductive sleeves 201 are sleeved on the conductive terminals 101 and are electrically connected to the conductive terminals 101; a plurality of insertion parts 202 are arranged on the female end 2, the plurality of insertion parts 202 are evenly arranged circumferentially, penetrate through the mounting disc 103, and are inserted into the mounting area, the insertion parts 202 are located inside the balls 106 and form a stop fit with the balls 106.

[0023] Specifically in this embodiment, the male end 1 includes a first housing 107. A first base column 108 is fixedly inserted in the first housing 107. When installed, the inner ends of the conductive terminals 101 are inserted into the first base column 108, and the outer ends are located outside the first base column 108. The conductive terminals 101 extend in a direction parallel to the axis of the first base column 108, and the plurality of conductive terminals 101 are evenly arranged circumferentially about the axis of the first base column 108 and are configured to form an electrical connection with the first cable 5.

[0024] The female end 2 includes a second housing 203. A second base column 204 is fixedly inserted in the second housing 203, and the axes of the second base column 204 and the first base column 108 are arranged to coincide with each other during installation. To facilitate the installation of the conductive sleeve 201, a plurality of first mounting holes 2041 are provided on the outer end surface of the second base column 204, and the plurality of first mounting holes 2041 are evenly arranged along the circumferential direction with respect to the axis of the second base column 204, and a conductive sleeve 201 is inserted in each first mounting hole 2041, and the conductive sleeve 201 is configured to form an electrical connection with the second cable 6. The mounting plate 103 is coaxially arranged on the outer end face of the first base column 108 during installation, and is detachably connected to the first base column 108 by screws; in order to facilitate the passage of the conductive terminal 101, a plurality of second mounting holes 1031 are provided through the large end face of the mounting plate 103, and the plurality of second mounting holes 1031 are evenly arranged along the circumferential direction with respect to 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, so as to avoid interference when the adjusting ring 102 drives the conductive terminal 101 to swing outward; in order to facilitate the passage of the plug-in portion 202, a plurality of third mounting holes 1032 are provided through the large end face of the mounting plate 103, and the plurality of third mounting holes 1032 are evenly arranged along the circumferential direction with respect to the axis of the mounting plate 103. In order to achieve the waterproof and dustproof function, the end faces of the first base column 108 and the second base column 204 can be arranged to abut against each other, and a sealing ring is inserted and sealed at the end face.

[0025] The limiting ring 104 and the pushing ring 105 are arranged opposite to each other, and an annular opening is formed between the two. 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 columnar 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 at the end of the first part, and the center of the second part coincides with the axis of the first part. The second part can form a stopper with the ball 106 when in use. In order to facilitate the passage of the conductive terminal 101, a plurality of fourth mounting holes 1021 are arranged through the annular surface of the adjusting ring 102, and the plurality of fourth mounting holes 1021 are evenly arranged along the circumferential direction with respect to the axis of the adjusting 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 by cooperating with the stoppers between the plug-in parts 202 and the balls 106.

[0026] During the plugging process between 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 .

[0027] When the insertion part 202 continues to advance, its spherical second part contacts the ball 106 and applies a radial thrust, causing the ball 106 to move outward. Based on the principle of force transmission, the ball 106 conducts this acting force to the push ring 105 with an L-shaped cross-section. Since the push ring 105 is made of a material with good plastic deformation ability (such as engineering plastics), under the extrusion of the ball 106, the push ring 105 gradually undergoes plastic deformation and gradually evolves from the initial ring structure into a conical shape. During this process, the inner conical surface of the push ring 105 closely contacts the adjusting ring 102 and generates an axial compressive force, prompting the adjusting ring 102 to undergo elastic deformation.

[0028] When the adjusting ring 102 is axially compressed, the geometric shape change of its corrugated folds is converted into a radial expansion force, which in turn drives a plurality of conductive terminals 101 sleeved thereon to swing radially outward, significantly increasing the contact area between the conductive terminals 101 and the conductive sleeve 201. On the one hand, by increasing the mechanical engagement points, the mechanical connection fastening degree between the two is strengthened; on the other hand, the closer physical contact effectively reduces the contact resistance, significantly improving the electrical connection performance and ensuring the stability of signal transmission and the efficiency of electrical energy conduction.

[0029] When the second part of the insertion part 202 passes beyond the center position of the ball 106, the adjusting ring 102 begins to release the stored elastic potential energy and partially reset due to the resilience of its own elastic material; the reset movement of the adjusting ring 102 drives the push ring 105 to retract towards the initial position through the mechanical linkage relationship between the push ring 105 and the ball 106, and at the same time makes the ball 106 move towards the axial center direction within the installation area; finally, the ball 106 and the insertion part 202 form a bidirectional clamping state to achieve self-locking. Through the combination of the point contact constraint of the ball 106 and the surface contact constraint of the push ring 105, multi-dimensional mechanical locking between the male end 1 and the female end 2 is realized, effectively resisting the influence of external environmental factors such as vibration and impact on the connection structure, and ensuring the stable connection and reliable operation of the electrical connector under complex working conditions.

[0030] In a further embodiment, the push ring 105 is a conical structure, and the flared opening faces the adjusting ring 102.

[0031] During use, when the insertion part 202 pushes the ball 106 to move outward, the contact point between the ball 106 and the inner wall of the pushing ring 105 changes accordingly; based on the principle of force decomposition, the force exerted by the ball 106 on the pushing ring 105 can be decomposed into an axial pressure and a radial contraction force. Under the combined action of these two forces, local plastic deformation occurs in the conical flared area of the pushing ring 105. The part near the contact point of the ball 106 first undergoes inward contraction, forming a "dynamic necking effect". This necking change is not evenly distributed, but shows a gradient change according to the movement trajectory and the magnitude of the force of the ball 106. The closer the area is to the ball 106, the greater the degree of necking, thus forming a gradually narrowing deformation area.

[0032] The generation of this deformation area significantly enhances the compression effect on the adjusting ring 102: on the one hand, the narrowing flared opening increases the contact pressure with the adjusting ring 102, enabling the adjusting ring 102 to bear a greater compression load under the same displacement, and thus generating a more significant elastic deformation; on the other hand, the shape change of the necking of the pushing ring 105 forms a geometric fit with the corrugated structure of the adjusting ring 102. While the contact area between the two increases, it can also guide the adjusting ring 102 to deform in a predetermined direction, ensuring that the conductive terminal 101 swings outward at an optimal angle to achieve a closer mechanical bite and electrical connection with the conductive sleeve 201.

[0033] In addition, the conical structure of the pushing ring 105 also has a self-resetting guiding function. During the elastic recovery stage of the adjusting ring 102, its gradually narrowing inner wall can provide an accurate reset guiding path for the ball 106, helping the ball 106 to return smoothly and completing the locking process of the male end 1 and the female end 2.

[0034] In some other embodiments, to further improve the connection strength between the male end 1 and the female end 2, the waterproof and dustproof electrical connector further includes a connection assembly 3, and the connection assembly 3 is configured to be able to connect the male end 1 and the female end 2.

[0035] In a further embodiment, the connection assembly 3 is provided to include a threaded sleeve 301 and a threaded protective cylinder 302. The threaded sleeve 301 is sleeved on the female end 2, and can both rotate around its own axis and move along its own axis direction, and forms a stop fit with the female end 2; the threaded protective cylinder 302 is sleeved on the male end 1 and is threadedly inserted into the threaded sleeve 301.

[0036] Specifically in this embodiment, the threaded sleeve 301 is sleeved on the second housing 203 during installation; to achieve the 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 on the second housing 203 during installation and can abut against the end face of the first annular platform 2031, so that the threaded sleeve 301 and the female end 2 form a stop fit. The threaded protective cylinder 302 is coaxially arranged with the first base column 108 and is sleeved on 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 protective cylinder 302 enclose a sealed chamber, thereby achieving waterproof and dustproof functions.

[0037] During use, after the insertion part 202 is clamped by the ball 106, rotate the threaded sleeve 301 so that the threaded sleeve 301 is threadedly sleeved on the threaded protective cylinder 302 until the first annular platform 2031 and the second annular 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 protective cylinder 302.

[0038] In a further embodiment, to facilitate the maintenance of the conductive terminal 101, the threaded protective cylinder 302 and the male end 1 are configured to form a threaded fit.

[0039] Specifically in this embodiment, an installation ring 1071 is provided on the end face of the first housing 107 facing the female end 2. The installation ring 1071 is sleeved on the outside of the first base column 108, and the threaded protective cylinder 302 is threadedly sleeved on the installation ring 1071 during installation.

[0040] During use, when the conductive terminal 101 needs to be maintained, the threaded protective cylinder 302 can be removed from the installation ring 1071, so that the conductive terminal 101 is exposed, facilitating operation.

[0041] In other embodiments, in an electrical connection system, to avoid problems such as connection errors, short circuits, and even equipment damage caused by misinsertion, anti-misinsertion design is crucial. To achieve an effective anti-misinsertion function, the waterproof and dustproof electrical connector further includes an anti-misinsertion component, and the anti-misinsertion component is configured to enable the conductive terminal 101 and the conductive sleeve 201 to be connected in a one-to-one correspondence.

[0042] Specifically in this embodiment, the setting of the anti-misinsertion component can ensure that the conductive terminal 101 and the conductive sleeve 201 are connected in a one-to-one correspondence accurately, thereby significantly improving the reliability and stability of the connection.

[0043] In a further embodiment, the anti-fooling component is arranged to include a guide groove 401 and a guide platform 402. The guide groove 401 is arranged on the female end 2; the guide platform 402 is arranged on the inner peripheral wall of the threaded sleeve 302, and the guide platform 402 is inserted into the guide groove 401.

[0044] Specifically in this embodiment, the guide platform 402 is an arc-shaped strip structure and extends along a direction parallel to the axis of the threaded sleeve 302. The guide groove 401 is an arc-shaped strip structure and is arranged on the circumferential side wall of the second base pillar 204 and extends along a direction parallel to the axis of the second base pillar 204.

[0045] During actual use, whether the guide platform 402 and the guide groove 401 are aligned becomes the key condition for the successful 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 to achieve the insertion operation between the two. At this time, due to the precise positioning function of the anti-fooling component, the conductive terminals 101 and the conductive sleeves 201 will be connected according to the preset corresponding relationship, that is, the corresponding connection is achieved. This corresponding connection method can effectively avoid connection errors caused by misinsertion, 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, and at the same time reducing the safety hazards caused by connection errors and ensuring the stable operation of the entire electrical system.

[0046] In other embodiments, in order to prevent hand slippage, anti-slip lines 3011 are provided on the outer peripheral wall of the threaded sleeve 301.

[0047] In a further embodiment, the anti-slip lines 3011 are a mesh structure.

[0048] Specifically in this embodiment, the mesh structure is composed of criss-crossing lines. Compared with single-direction stripes or dot-like lines, it can make contact with the operator's hand in multiple dimensions, significantly increasing the contact area. When the operator holds the threaded sleeve 301, multiple tiny meshing points are formed between the hand skin and the mesh anti-slip lines 3011. These meshing points interact when a gripping force is applied to form a greater static friction force, effectively preventing the hand from sliding relative to the threaded sleeve 301.

[0049] In addition, the structure of the mesh anti-slip lines 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 lines, avoiding discomfort caused by local pressure concentration, and at the same time reducing wear caused by long-term use and extending the effective service life of the anti-slip lines 3011.

[0050] In some other embodiments, the adjusting ring 102 is made of plastic material.

[0051] Specifically in this embodiment, during the insertion of the male end 1 and the female end 2, the adjusting ring 102 needs to withstand the extrusion of the push ring 105 and drive the conductive terminal 101 to swing. The plastic material can produce a controllable displacement when subjected to force by virtue of its elastic deformation ability, ensuring that the conductive terminal 101 is in close contact with the conductive sleeve 201. Taking common thermoplastic elastomers (TPE) or thermoplastic polyurethanes (TPU) as an example, this type of plastic has both the elasticity of rubber and the processing characteristics of plastic, and its elastic modulus and hardness can be adjusted through the formula to meet the deformation requirements of the adjusting ring 102 under different working conditions.

[0052] In addition, the plastic material has excellent insulation properties, which can effectively prevent accidental conduction between the adjustment ring 102 and the conductive terminal 101, thereby ensuring the electrical safety of the electrical connector. At the same time, the plastic has good chemical stability and can withstand erosion from a variety of environmental factors, such as moisture, corrosive gases, etc. This allows the adjustment ring 102 to maintain structural integrity and stable performance when the electrical connector is used in a complex environment. From a cost perspective, the price of plastic materials is lower than that of metals, and the energy consumption of the processing process is lower, which helps to reduce the overall production cost of the electrical connector.
