[0034] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0035] The embodiment of the present application provides a connector, which solves the problem that the existing connector is not waterproof, is easily infiltrated with water when used outdoors, and has a limited scope of use.

[0036] refer to Figure 1 and Figure 2The connector provided in the embodiment of the present application includes a male plug 1, a female plug 2 and a first waterproof ring 3. The male plug 1 is provided with a pin 10, and the male plug 1 includes a male plug mating section 101, and the outer wall surface of the male plug mating section 101 is a male plug mating surface; the female plug 2 is provided with a sleeve 20 that matches the pin 10, and the female plug 2 includes a female plug mating section 201, and the outer wall of the female plug mating section 201 is provided with a sleeve cavity 2011 that is adapted to the outer contour of the female plug 2, and the inner surface of the sleeve cavity 2011 is a female plug mating surface; the first waterproof ring 3 is arranged between the male plug mating surface and the female plug mating surface to seal the male plug mating surface and the female plug mating surface.

[0037] In the embodiment of the present application, a sleeve cavity 2011 that is adapted to the outer contour of the female plug 2 is provided on the outer wall of the female plug mating section 201, the inner surface of the sleeve cavity 2011 is the female plug mating surface, and the outer wall surface of the male plug mating section 101 is the male plug mating surface. When the male plug 1 and the female plug 2 are plugged together, the male plug mating section 101 will extend into the sleeve cavity 2011. At this time, the male plug mating surface and the female plug mating surface are opposite to each other, and a first waterproof ring 3 is provided between the male plug mating surface and the female plug mating surface. In this way, the connection between the male plug 1 and the female plug 2 can be made waterproof, and the entire connector has a waterproof function. When the connector is used outdoors, water will not enter, and the scope of use is wider.

[0038] It should be noted that when the male plug 1 and the female plug 2 are plugged together, the pin 10 will be inserted into the socket 20, thereby achieving electrical connection between the male plug 1 and the female plug 2, so that the connector can achieve power transmission or signal transmission.

[0039] In some embodiments, the end of the socket 20 is configured to include a plurality of elastic members, and the plurality of elastic members can be shrunk together or separated from each other. The end of the pin 10 is configured to be tapered, so that the pin 10 can be quickly inserted into the socket 20. When the pin 10 is inserted into the socket 20, the plurality of elastic members of the socket 20 will be stretched open, and the plurality of elastic members will apply elastic force to the pin 10, so that the pin 10 can be firmly inserted into the socket 20.

[0040] Example, reference Figure 3 and Figure 4 The embodiment of the present application may have four pins 10, and correspondingly, four sockets 20 are also provided. The four pins 10 are inserted into the four sockets 20 one by one to realize the plug-in connection between the male plug 1 and the female plug 2, so that the connector can achieve the purpose of power transmission or signal transmission.

[0041] In some embodiments, reference Figure 3, the first waterproof ring 3 is sleeved on the male plug-in fitting section 101. In this way, the first waterproof ring 3 can be more firmly connected to the male plug-in fitting section 101, so that after the male plug 1 and the female plug 2 are plugged and connected, the first waterproof ring 3 can abut against the female plug-in fitting surface, so that the male plug-in fitting surface and the female plug-in fitting surface are sealed and connected, thereby realizing the waterproof function of the connector.

[0042] Specifically, the first waterproof ring 3 can be made of silicone material, so that the first waterproof ring 3 has a certain elasticity, so that it can better fit the male plug mating surface and the female plug mating surface, so that the sealing effect between the male plug mating surface and the female plug mating surface is better, and the waterproof effect of the connector is better.

[0043] In some embodiments, reference Figure 3 The male plug fitting section 101 is provided with a sealing groove, the first waterproof ring 3 is located in the sealing groove, and the outer ring of the first waterproof ring 3 protrudes from the male plug fitting surface. In this way, the first waterproof ring 3 can be firmly arranged on the male plug fitting section 101, so that it will not fall off from the tolerance fitting section during the plugging process of the male plug 1 and the female plug 2, and the gap between the male plug fitting surface and the female plug fitting surface can be filled by the first waterproof ring 3, which is conducive to enhancing the waterproof effect.

[0044] It should be noted that there is a certain gap between the sealing groove and the beginning and the end of the male plug fitting section 101. Two circles of mutually adjacent sealing grooves can be set on the tolerance fitting section, and a first waterproof ring 3 is set in each circle of sealing grooves. Specifically, the first waterproof ring 3 can be bonded to the sealing groove by sealant, so that the contact area between the first waterproof ring 3 and the male plug fitting surface and the female plug fitting surface can be increased, so that the sealing area is increased and the waterproof effect is better. In addition, the outer ring of the first waterproof ring 3 protrudes from the male plug fitting surface, that is, the first waterproof ring 3 protrudes from the outer wall surface of the male plug fitting section 101, so that when the male plug 1 and the female plug 2 are assembled, the first waterproof ring 3 can use its own elasticity to fill the gap between the male plug fitting surface and the female plug fitting surface (not shown). Thereby achieving a sealing connection effect between the male plug fitting surface and the female plug fitting surface, which is conducive to realizing the waterproof function of the connector.

[0045] In addition to setting the first waterproof ring 3 in the sealing groove set on the male plug-in fitting section 101, the same technical means can be used to open a sealing groove on the inner surface of the sleeve cavity 2011, and the outer ring of the first waterproof ring 3 protrudes from the inner surface of the sleeve cavity 2011, and there is a certain gap between the first waterproof ring 3 and the head and the end of the sleeve cavity 2011. Alternatively, the sealing grooves for placing the first waterproof ring 3 can be set on the inner surfaces of the male plug-in fitting section 101 and the sleeve cavity 2011 at the same time. In fact, as long as the sealing groove is set between the male plug-in fitting surface and the female plug-in fitting surface, it does not matter which means are used.

[0046] In some embodiments, reference Figure 3 The male plug 1 includes a male plug cavity 100 having a male plug first port 1001 and a male plug end port 1002, a pin pressing block 11 is provided in the male plug cavity 100, and the male plug end port 1002 is covered with a male plug back cover 12; a first waterproof sheet 13 is provided between the pin pressing block 11 and the male plug back cover 12, the pin 10 is inserted on the pin pressing block 11, and the wiring harness connected to the pin 10 passes through the first waterproof sheet 13 and the male plug back cover 12 in sequence.

[0047] Specifically, a pin hole is provided on the bottom wall of the male plug cavity 100, the pin 10 is inserted into the pin pressing block 11, and then the pin pressing block 11 and the pin 10 are inserted into the male plug cavity 100 from the male plug end port 1002, so that the pin 10 is inserted from the pin hole and exposed from the male plug first port 1001, a male plug back cover 12 is provided on the male plug end port 1002, and a first waterproof sheet 13 is provided between the pin pressing block 11 and the male plug back cover 12, so that the position of the pin 10 and the pin pressing block 11 can be fixed in the male plug cavity 100 and is not prone to shaking. In this structure, since the wiring harness connected to the pin 10 needs to pass through the male plug back cover 12, it will be easy for water to leak from the hole opened on the male plug back cover 12 into the male plug cavity 100. However, the wiring harness connected to the pin 10 first passes through the first waterproof sheet 13 and then passes through the male plug back cover 12. In this way, the first waterproof sheet 13 will be tightly attached to the wiring harness connected to the pin 10, and the first waterproof sheet 13 is also tightly attached to the male plug back cover 12. In this way, the gap between the wiring harness connected to the pin 10 and the first waterproof sheet 13 or the gap between the wiring harness connected to the pin 10 and the male plug back cover 12 can be effectively avoided to leak water, thereby achieving a good waterproof effect.

[0048] It should be noted that a specific implementation of the male plug back cover 12 being arranged on the male plug end port 1002 may be: the male plug 1 also includes a male plug base section 102, a male tail bump is arranged on the male plug base section 102, and a clamping hole is arranged on the male plug back cover 12. During installation, the clamping hole of the male plug back cover 12 is clamped on the male tail bump to achieve the connection between the male plug back cover 12 and the male plug base section 102, and cover the male plug end port 1002. This not only enables the male plug back cover 12 to be installed more firmly, but also makes the operation of installing the male plug back cover 12 simpler, and facilitates installation and disassembly.

[0049] In some embodiments, reference Figure 4 The female plug 2 includes a female plug cavity 200 having a female plug front port 2001 and a female plug rear port 2002, a socket pressing block 21 is provided in the female plug cavity 200, and a female plug rear port 2002 is covered with a female plug back cover 22; a second waterproof sheet 23 is provided between the socket pressing block 21 and the female plug back cover 22, the socket 20 is inserted on the socket pressing block 21, and the wiring harness connected to the socket 20 passes through the second waterproof sheet 23 and the female plug back cover 22 in sequence.

[0050] Specifically, a socket hole is provided in the female plug cavity 200, the socket 20 is inserted into the socket pressing block 21, and then the socket pressing block 21 and the socket 20 are inserted into the female plug cavity 200 from the female plug end port 2002, so that the socket 20 is inserted into the socket hole and exposed from the female plug first port 2001, a female plug rear cover 22 is provided at the female plug end port 2002, and a second waterproof sheet 23 is provided between the socket pressing block 21 and the female plug rear cover 22, so that the socket 20 and the socket pressing block 21 can be fixed in position in the female plug cavity 200 and are not prone to shaking. In this structure, since the wiring harness connected to the socket 20 needs to pass through the female socket rear cover 22, it will be easy for water to leak from the hole opened on the female socket rear cover 22 into the female socket cavity 200. However, the wiring harness connected to the socket 20 first passes through the second waterproof sheet 23 and then passes through the female socket rear cover 22. In this way, the second waterproof sheet 23 will be tightly attached to the wiring harness connected to the socket 20, and the second waterproof sheet 23 is also tightly attached to the female socket rear cover 22. In this way, it is possible to effectively avoid water leakage from the gap between the wiring harness connected to the socket 20 and the second waterproof sheet 23 or the gap between the wiring harness connected to the socket 20 and the female socket rear cover 22, thereby achieving a good waterproof effect.

[0051] It should be noted that a specific implementation of the female plug back cover 22 being arranged on the female plug end port 2002 may be: the female plug 2 also includes a female plug base section 202, a female tail protrusion is arranged on the female plug base section 202, and a card hole is arranged on the female plug back cover 22. During installation, the card hole of the female plug back cover 22 is carded on the female tail protrusion to achieve the connection between the female plug back cover 22 and the female plug base section 202, and cover the female plug end port 2002. This not only enables the female plug back cover 22 to be installed more firmly, but also makes the operation of installing the female plug back cover 22 simpler, and facilitates installation and disassembly.

[0052] In some embodiments, a first jack 130 is provided on the first waterproof sheet 13, and the wiring harness connected to the pin 10 has an interference fit with the first jack 130; a second jack 230 is provided on the second waterproof sheet 23, and the wiring harness connected to the socket 20 has an interference fit with the second jack 230.

[0053] Since the first waterproof sheet 13 has a certain elasticity, when the wiring harness connected to the pin 10 is interference-fitted with the first jack 130, the first waterproof sheet 13 will apply elastic force to the wiring harness connected to the pin 10, so that the wiring harness connected to the pin 10 and the first waterproof sheet 13 are sealed and connected, thereby preventing the first jack 130 from leaking and affecting the waterproof effect of the connector. Similarly, since the second waterproof sheet 23 has a certain elasticity, when the wiring harness connected to the socket 20 is interference-fitted with the second jack 230, the second waterproof sheet 23 will apply elastic force to the wiring harness connected to the socket 20, so that the wiring harness connected to the socket 20 and the second waterproof sheet 23 are sealed and connected, thereby preventing the second jack 230 from leaking and affecting the waterproof effect of the connector.

[0054] It should be noted that both the first waterproof sheet 13 and the second waterproof sheet 23 can be made of silicone material, which can improve the utilization rate of the material, and the silicone has a certain elasticity, which can make the wiring harness connected to the pin 10 and the first waterproof sheet 13 sealed, and the wiring harness connected to the socket 20 and the second waterproof sheet 23 sealed, and the wiring harness connected to the pin 10 will not cause damage to the surface of the wiring harness when passing through the first jack 130, and the wiring harness connected to the socket 20 will not cause damage to the surface of the wiring harness when passing through the second jack 230. In addition, when setting the first jack 130, it is necessary to pay attention to setting the diameter of the first jack 130 to be smaller than the diameter of the wiring harness connected to the pin 10, and when setting the second jack 230, it is necessary to pay attention to setting the diameter of the second jack 230 to be smaller than the diameter of the wiring harness connected to the socket 20.

[0055] In some embodiments, the first waterproof sheet 13 and the second waterproof sheet 23 can be set to a multi-layer structure, that is, a plurality of waterproof sheets are stacked to form the first waterproof sheet 13 and the second waterproof sheet 23. In this way, the thickness of the first waterproof sheet 13 and the second waterproof sheet 23 can be enhanced, so that the elasticity of the first waterproof sheet 13 and the second waterproof sheet 23 is enhanced, which is beneficial for the first waterproof sheet 13 to abut against the pin pressing block 11 and the male plug back cover 12 respectively, and the second waterproof sheet 23 to abut against the socket pressing block 21 and the female plug back cover 22 respectively, so as to achieve good sealing and better waterproof effect.

[0056] In some embodiments, reference Figure 3 and Figure 4 The male plug cavity 100 is provided with an anti-foolproof sleeve 2003 with a regular hexagonal cross-section, and the anti-foolproof sleeve 2003 is provided with a male plug anti-foolproof identification piece 14; the female plug cavity 200 is provided with a female plug anti-foolproof identification piece 24, and the female plug anti-foolproof identification piece 24 is connected to the male plug anti-foolproof identification piece 14 through a concave and convex matching structure to form a columnar body with a regular hexagonal cross-section.

[0057] Through the above arrangement, since the male plug anti-mistake identification piece 14 and the female plug anti-mistake identification piece 24 cooperate with each other, when the male plug 1 and the female plug 2 are plugged in, the mismatch in specifications of the plugged male plug 1 and the female plug 2 can be effectively avoided, and the male plug 1 and the female plug 2 can be plugged in more accurately and quickly, making them more convenient to use.

[0058] It should be noted that the anti-mistake sleeve 2003 is set to have a regular hexagonal cross-section. After the male plug 1 and the female plug 2 are plugged together, not only the female plug anti-mistake identification piece 24 must cooperate with the male plug anti-mistake identification piece 14, but also the structure formed by the female plug anti-mistake identification piece 24 and the male plug anti-mistake identification piece 14 being connected together must be a columnar body with a regular hexagonal cross-section. This can ensure that the specifications of the male plug 1 and the female plug 2 that are plugged together are matched with each other, for example, the voltage and current that the male plug 1 can pass are the same as the voltage and current that the female plug 2 can pass.

[0059] For example, the shapes of the female plug anti-mistake identification member 24 and the male plug anti-mistake identification member 14 are not specifically limited, as long as they meet the above requirements. Figure 3 The male plug foolproof identification member 14 can be arranged in the female plug cavity 200. Figure 4 The female plug fool-proof identification member 24 can be set in the fool-proof sleeve 2003 in the male plug cavity 100.

[0060] In some embodiments, reference Figure 3 and Figure 4 The male plug 1 also includes a male plug base section 102, on which a first groove 103 is provided, and two side walls of the first groove 103 along the extending direction of the pin 10 are provided with a third plug hole 1030, and the male plug anti-foolproof identification member 14 has a male plug identification surface 140, and the male plug anti-foolproof identification member 14 is inserted into the third plug hole 1030 so that the male plug identification surface 140 is exposed from the notch of the first groove 103; the female plug 2 also includes a female plug base section 202, on which a second groove 203 is provided, and two side walls of the second groove 203 along the extending direction of the socket 20 are provided with a fourth plug hole 2030, and the female plug anti-foolproof identification member 24 has a female plug identification surface 240, and the female plug anti-foolproof identification member 24 is inserted into the fourth plug hole 2030 so that the female plug identification surface 240 is exposed from the notch of the second groove 203.

[0061] Through the above arrangement, after the male plug anti-mistake identification piece 14 is installed in the anti-mistake sleeve 2003, the male plug identification surface 140 will be exposed from the notch of the first groove 103, and the specifications of the male plug 1, that is, the voltage value and current value that the male plug 1 can pass, can be printed on the male plug identification surface 140. In this way, not only can it be judged whether the installation direction of the male plug anti-mistake identification piece 14 is correct by observing the male plug identification surface 140, but also the specification parameters of the male plug 1 can be understood by observing the male plug identification surface 140, so that the user can accurately use the male plug 1 with the required specification parameters, thereby preventing the user from plugging together the male plug 1 and the female plug 2 of different specifications, causing connector failure and damage.

[0062] Similarly, after the female plug anti-mistake identification piece 24 is installed in the female plug cavity 200, the female plug identification surface 240 will be exposed from the notch of the second groove 203, and the specifications of the female plug 2, that is, the voltage and current values ​​that the female plug 2 can pass, can be printed on the female plug identification surface 240. In this way, not only can it be judged whether the installation direction of the female plug anti-mistake identification piece 24 is correct by observing the female plug identification surface 240, but also the specification parameters of the female plug 2 can be understood by observing the female plug identification surface 240, so that the user can accurately use the female plug 2 with the required specification parameters, thereby preventing the user from plugging together the male plug 1 and the female plug 2 of different specifications, causing connector failure and damage.

[0063] In addition, the first groove 103 and the second groove 203 can be respectively arranged on the same side surface of the male plug 1 and the female plug 2, that is, when the male plug 1 and the female plug 2 are plugged together, the first groove 103 and the second groove 203 are located on the same side, so that the male plug 1 and the female plug 2 can be quickly and accurately plugged together through the positions of the first groove 103 and the second groove 203, avoiding the male plug 1 and the female plug 2 from being plugged in opposite directions and then swapped, thereby causing damage to the pin 10 and the socket 20, and affecting the plugging efficiency of the male plug 1 and the female plug 2.

[0064] In some embodiments, reference Figure 3 and Figure 4 A second waterproof ring 4 is sleeved on the male plug anti-mistake identification piece 14, and the second waterproof ring 4 abuts against the outer surface of the side wall of the first groove 103 close to the male plug fitting section 101; a third waterproof ring 5 is sleeved on the female plug anti-mistake identification piece 24, and the third waterproof ring 5 abuts against the outer surface of the side wall of the second groove 203 close to the female plug fitting section 201.

[0065] It should be noted that, due to the setting of the third jack 1030, water leakage may occur in the gap between the male plug anti-foolproof identification piece 14 and the side wall of the first groove 103. Therefore, a second waterproof ring 4 is sleeved on the male plug anti-foolproof identification piece 14, so that the second waterproof ring 4 abuts against the outer surface of the side wall of the first groove 103 close to the male plug fitting section 101, that is, the gap between the male plug anti-foolproof identification piece 14 and the side wall of the first groove 103 is blocked, which can effectively prevent water leakage. In addition, the outer surface of the side wall of the first groove 103 away from the male plug fitting section 101 will extend to the male plug end port 1002 and contact the male plug back cover 12. Due to the setting of the first waterproof sheet 13, the third jack 1030 set on the side wall of the first groove 103 away from the male plug fitting section 101 will not leak. In this way, water leakage can be well prevented from occurring at the third jack 1030, which is conducive to realizing the waterproof function of the connector.

[0066] Similarly, due to the setting of the fourth jack 2030, water leakage may occur in the gap between the female plug anti-foolproof identification piece 24 and the side wall of the second groove 203. Therefore, a third waterproof ring 5 is sleeved on the female plug anti-foolproof identification piece 24, so that the third waterproof ring 5 abuts against the outer surface of the side wall of the second groove 203 close to the female plug mating section 201, that is, the gap between the female plug anti-foolproof identification piece 24 and the side wall of the second groove 203 is blocked, which can effectively prevent water leakage. In addition, the outer surface of the side wall of the second groove 203 away from the female plug mating section 201 will extend to the female plug end port 2002 and contact the female plug back cover 22. Due to the setting of the second waterproof sheet 23, the fourth jack 2030 set on the side wall of the second groove 203 away from the female plug mating section 201 will not leak. In this way, water leakage can be well prevented from occurring at the fourth jack 2030, which is conducive to realizing the waterproof function of the connector.

[0067] In some embodiments, reference Figure 3 and Figure 4 The male plug 1 is used to connect the male power cable 6, and the male plug 1 and the male power cable 6 are integrally injection molded; the female plug 2 is used to connect the female power cable 7, and the female plug 2 and the female power cable 7 are integrally injection molded.

[0068] Through the above configuration, not only the connection efficiency between the male plug 1 and the male power cable 6 can be improved, but also the connection position between the male plug 1 and the male power cable 6 can achieve a waterproof effect. Not only the connection efficiency between the female plug 2 and the female power cable 7 can be improved, but also the connection position between the female plug 2 and the female power cable 7 can achieve a waterproof effect.

[0069] It should be noted that, during the production process, the male power cable 6 is placed in the mold to form the male plug 1 as an integral unit, so that the male power cable 6 will be connected during the production process of the male plug 1, and the female power cable 7 is placed in the mold to form the female plug 2 as an integral unit, so that the female power cable 7 will be connected during the production process of the female plug 2, thereby greatly improving the production efficiency.

[0070] In the embodiment of the present application, the male plug 1 and the male power cable 6 are integrally injection molded, and the female plug 2 and the female power cable 7 are integrally injection molded, so as to achieve waterproofing at the connection between the male plug 1 and the male power cable 6 and at the connection between the female plug 2 and the female power cable 7; by installing the plug pin 10 and the plug sleeve 20 separately, not only can the plug pin 10, the plug sleeve 20 and other parts be separately manufactured, so as to improve the manufacturing efficiency; by setting the first waterproof ring 3, the sealing of the plug connection between the male plug 1 and the female plug 2 is achieved, so as to achieve waterproofing at the connection between the male plug 1 and the female plug 2. In this way, the connector can be waterproofed as a whole, and there will be no water leakage when the connector is used outdoors, so the scope of use is wider.

[0071] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
