[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0042] Connectors are often used for electrical connection between two components, wherein the connector includes a male socket and a female socket. In order to ensure that the male socket and the female socket can be stably connected during use, the male socket and the female socket are usually fixedly connected by cooperating with a nut and a threaded section after the connector is connected. Under this structure, the male socket and the female socket can be prevented from separating. However, the existing connection method using a nut and a threaded section makes it inconvenient to disassemble the connector. Especially in the water purifier industry, due to the limited space inside the water purifier and in order to optimize the circuit inside the water purifier, when the connector with a wire is installed in the water purifier equipment, it is affected by the circuit optimization. When the connector with a wire is disassembled, it is inconvenient to remove the connector from the water purifier equipment. At this time, it is time-consuming and labor-intensive to remove the nut, which is inconvenient.

[0043] The utility model provides an integrated self-locking waterproof electrical connector.

[0044] See also Figure 1 , Figure 2 In one embodiment of the utility model, the integrated self-locking waterproof electrical connector comprises:

[0045] A first connection part 100, wherein the first connection part 100 is provided with a first conductive pin 110; a second connection part 200, wherein the second connection part 200 is connected to the first connection part 100 and is provided with a second conductive pin 210, when the second connection part 200 is connected to the first connection part 100, the first conductive pin 110 is connected with the second conductive pin 210, so that the circuit is turned on, wherein the first conductive pin 110 and the second conductive pin 210 can be directly connected or indirectly connected. When the first conductive pin 110 and the second conductive pin 210 are directly connected, that is, the first conductive pin 110 and the second conductive pin 210 are in direct contact. When the first conductive pin 110 and the second conductive pin 210 are indirectly connected, that is, the first conductive pin 110 and the second conductive pin 210 are connected through other conductive structures, so that the circuit is turned on. One of the first connection part 100 and the second connection part 200 is provided with an active buckle 400, and the other is provided with a buckle position 300 corresponding to the active buckle 400.

[0046] The rotating tube 500 is fixed to the active buckle 400 and is rotatably mounted on the first connection part 100 or the second connection part 200. When the rotating tube 500 rotates, the active buckle 400 can also rotate with it. Specifically, the rotating tube 500 is sleeved on the first connection part 100 or the second connection part 200, so as to facilitate the user to operate the rotating tube 500 to rotate. The rotating tube 500 is used to make the active buckle 400 have a locked state that is engaged with the buckle position 300 and an unlocked state that is separated from the buckle position 300. When the rotating tube 500 is rotated, the active buckle 400 can be switched from the locked state to the unlocked state. In this way, when the first connection part 100 and the second connection part 200 are disassembled, the rotating tube 500 is twisted to make the active buckle 400 in the unlocked state, and then the staff can separate the first connection part 100 and the second connection part 200. The operation is simple and very convenient, which is simpler than rotating by a nut in the prior art. At the same time, in this embodiment, by adopting a rotating tube 500 with a circular tubular structure, the connector occupies less space in a small and cramped space, and can avoid interference with other objects during rotation, thereby further facilitating the staff to disassemble the connector and further improving the use effect of the present application.

[0047] The technical solution of the present invention is to provide an active buckle 400 on one of the first connection part 100 and the second connection part 200, and to provide a buckle position 300 on the other corresponding to the active buckle 400, wherein the active buckle 400 is fixed to the rotating tube 500, and the rotating tube 500 is rotatably installed on the first connection part 100 or the second connection part 200. When in use, the active buckle 400 is unlocked by twisting the rotating tube 500, and then the staff separates the first connection part 100 and the second connection part 200. The operation is simple and very convenient. Compared with the prior art of rotating by a nut, it is simpler and more convenient, and can solve the technical problems existing in the prior art; at the same time, in a narrow space, under the action of the rotating tube 500, the problem of interference between the rotating tube 500 and other structures and resulting in inability to rotate can be avoided.

[0048] In one embodiment, reference Figure 3 , Figure 4 , Figure 6 , wherein the plug-in connection between the first connection part 100 and the second connection part 200 can adopt the following structure, wherein the first connection part 100 includes a first base body 120, wherein the first base body 120 is provided with a first plug hole 140, and a plug-in part 130 matched with the second connection part 200, and the first conductive pin 110 is fixedly arranged in the first plug hole 140, wherein the first conductive pin 110 can be fixedly arranged in the first plug hole 140 by being integrally formed with the first base body 120, so that the connection between the first conductive pin 110 and the first plug hole 140 can be more stable. The second connection part 200 includes a second base body 220, wherein the second base body 220 is provided with a second plug hole 240, and a first slot 230 matched with the plug-in part 130, and the second conductive pin 210 is fixedly arranged in the second plug hole 240, wherein the second conductive pin 210 can be fixedly arranged in the second plug hole 240 by being integrally formed with the second base body 220.

[0049] In one embodiment, reference Figure 3 , Figure 4 The first connection part 100 also includes a second slot 150, and the second slot 150 is opened in the plug-in part 130. The second connection part 200 also includes a plug-in board 250, and the plug-in board 250 is plugged into the second slot 150. In this embodiment, the plug-in board 250 is configured as a V-shaped structure. In other embodiments, the plug-in board 250 can also adopt other structures. Under the action of the V-shaped structure, the first connection part 100 and the second connection part 200 can play a fool-proof effect when connected, which facilitates the plug-in of the first connection part 100 and the second connection part 200.

[0050] In one embodiment, reference Figure 4, the integrated self-locking waterproof electrical connector also includes a waterproof ring 600, and a mounting groove 160 is provided on the outside of the plug-in portion 130, and the mounting groove 160 is used for installing the waterproof ring 600; when the plug-in portion 130 is inserted into the first slot 230, the waterproof ring 600 is located between the plug-in portion 130 and the first slot 230. In this embodiment, the waterproof ring 600 adopts radial compression, and after the first connecting portion 100 and the second connecting portion 200 are connected, the inner wall surface of the second seat body 220 radially compresses the waterproof ring 600. In this way, the waterproof structure can be simple, the waterproof effect is good, and the service life is long. In this embodiment, the groove width of the mounting groove 160 is 2-5mm. Meanwhile, in this embodiment, by sleeve-arranging the waterproof ring 600 on the outside of the plug-in portion 130, when the plug-in portion 130 is inserted into the mounting groove 160, the waterproof ring 600 is radially compressed by the inner wall surface of the second seat body 220, that is, the wall surface of the first slot 230, thereby achieving a sealing effect between the plug-in portion 130 and the second seat body 220. Compared with the traditional radial compression seal, this sealing effect can avoid the problem of inconvenience in disassembly caused by the over-tight connection between the plug-in portion 130 and the first slot 230.

[0051] At the same time, the present application adopts a radial compression sealing ring 600 to achieve connector sealing. When the plug-in part 130 is inserted into the installation groove 160, a better sealing effect can be achieved, which can avoid the problem of poor waterproofness caused by the nut not being tightened in the prior art, and can make the connector more waterproof when in use.

[0052] Traditional radial compression seals are usually matched with nuts and threaded sections, and the seal is increased by increasing the pressure against the sealing ring. This operation is laborious during installation and disassembly, and for maintenance personnel with weak finger strength, auxiliary tools such as wrenches are required to achieve disassembly, which is more inconvenient. The present application twists the rotating tube 500 to put the active buckle 400 in an unlocked state, and then the staff separates the first connecting part 100 and the second connecting part 200. The operation is simple and very convenient, which is simpler than rotating the nut in the prior art.

[0053] In one embodiment, reference Figure 2 , Figure 4 The rotating tube 500 rotates on the first connecting portion 100, wherein the rotating tube 500 is rotatably mounted on the first seat body 120, the first seat body 120 is provided with an annular groove 170, and the rotating tube 500 is provided with a limit block 510 corresponding to the annular groove 170, and the limit block 510 is located in the annular groove 170, so that the rotating tube 500 can be prevented from being separated from the first seat body 120 when rotating on the first seat body 120. The corresponding buckle position 300 is provided on the second connecting portion 200, wherein the buckle position 300 is provided on the second seat body 220.

[0054] In one embodiment, the integrated self-locking waterproof electrical connector also includes a spring 700, which is installed on the first connecting part 100 to press against the rotating tube 500 so that the active buckle 400 is in a locked state, wherein the spring 700 is installed in the annular groove 170, and a limiting plate is provided in the annular groove 170, wherein one end of the spring 700 cooperates with the limiting plate, and the other end cooperates with the limiting block 510 in the rotating tube 500. When the rotating tube 500 is rotated, the limiting block 510 squeezes the spring 700 to compress the spring 700, and then the rotating tube 500 drives the active buckle 400 position 300 to be in an unlocked state.

[0055] In one embodiment, reference Figure 4 The movable buckle 400 is configured as a first protrusion, and the first protrusion has a first guide portion 410 and a first positioning portion 420; the buckle position 300 is configured as a second protrusion, and the second protrusion is provided on the second connecting portion 200, and the second protrusion has a second guide portion 310 and a second positioning portion 320; when the first connecting portion 100 and the second connecting portion 200 are connected, the first guide portion 410 and the second guide portion 310 are in contact, and the rotating tube 500 is rotated around the first connecting portion 100, and the spring 700 is squeezed at the same time, wherein the first guide portion 410 and the second guide portion 310 are both an inclined surface opened on the protrusion. In this embodiment, when the first connection part 100 and the second connection part 200 are connected, that is, during the plugging process of the first seat body 120 and the second seat body 220, the rotating tube 500 can be self-rotated under the cooperation of the first guide part 410 and the second guide part 310, and no artificial rotation is required, so that the first connection part 100 and the second connection part 200 are more efficient and more convenient to use during assembly. After the first connection part 100 and the second connection part 200 are connected, the spring 700 pushes the rotating tube 500 to rotate around the first connection part 100, so that the first positioning part 420 contacts the second positioning part 320, so that the movable buckle 400 is in a locked state.

[0056] In one embodiment, reference Figure 5 The first connecting portion 100 has a first end 180 that matches the second connecting portion 200, and the end surface of the first conductive needle 110 close to the first end 180 is 0-11 mm away from the first end 180. Figure 5In the middle a section, under this structure, the end face of the first conductive needle 110 close to the first end 180 can be located in the first seat body 120, so that when the first connection part 100 and the second connection part 200 are connected, that is, when the first seat body 120 and the second seat body 220 are plugged, under the action of the first seat body 120, the electric spark (arc) generated when the first conductive needle 110 and the second conductive needle 210 are connected can be shielded by the first seat body 120, avoiding the safety hazard caused by the electric spark when the connector is installed in a humid environment. At the same time, in this embodiment, when the end face of the first conductive needle 110 close to the first end 180 is greater than 11mm from the first end 180, the production cost of the connector will increase, which is not convenient for production and manufacturing. When the distance between the end face of the first conductive needle 110 close to the first end 180 and the first end 180 is less than 0 mm, that is, the first conductive needle 110 passes through the first end 180, when the first conductive needle 110 and the second conductive needle 210 are connected, the generated electric spark is easily exposed to the humid environment, thereby affecting the staff. In this embodiment, the distance between the end face of the first conductive needle 110 close to the first end 180 and the first end 180 can be selected to be 7.5 mm. At this distance, when the first conductive needle 110 and the second conductive needle 210 are in contact, the electric spark can be shielded by the first seat 120, so that the electric spark is not exposed to the humid environment. When the humidity in the humid environment is too high, the electric spark has the problem of causing the equipment in the humid environment to be conductive, wherein the electric spark is usually caused by a large high voltage. At this time, the equipment in the humid environment is prone to high voltage, so when the connector is disassembled and replaced in the water purifier (in a humid environment), it is very necessary to shield the electric spark from contact with humid air. At the same time, in this embodiment, when the distance between the end face of the first end 180 of the first conductive pin 110 and the first end 180 is 0 mm, 1 mm, or 2 mm, the second conductive pin 210 is located in the first slot 230. When the plug-in portion 130 is just inserted into the first slot 230, there is a certain distance between the first end 180 and the second conductive pin 210. At this time, no spark will be generated between the first conductive pin 110 and the second conductive pin 210. The vehicle plug-in portion 130 is continuously inserted, and the first conductive pin 110 and the second conductive pin 210 are in contact. At this time, under the action of the second seat body 220, the spark generated when the first conductive pin 110 and the second conductive pin 210 are in contact can be shielded and insulated at the same time.

[0057] In one embodiment, reference Figure 6 , the first conductive needle 110 is plugged into the second conductive needle 210, and the length of the overlapping portion is 3-7.5 mm, such as Figure 6In the present embodiment, when the overlapped portion is less than 3 mm, it is easy to cause the current to be unstable after the first connection portion 100 and the second connection portion 200 are connected. When the overlapped portion is greater than 7.5 mm, there is a problem of increased production cost. At the same time, when the overlapped portion is greater than 7.5 mm, it is not possible to shield the electric spark well, so that when the connector is assembled in a humid environment, the electric spark is easily exposed to the humid environment.

[0058] In one embodiment, reference Figure 3 , Figure 4 , the first conductive pin 110 is configured as a plurality, and the plurality of the first conductive pins 110 include a first power conductive pin 111 and a first signal conductive pin 112; the second conductive pin 210 is configured as a plurality, and the plurality of the second conductive pins 210 include a second power conductive pin 211 and a second signal conductive pin 212. In this embodiment, the first signal conductive pin 112 is connected to the second signal conductive pin 212, and the first power conductive pin 111 is connected to the second power conductive pin 211. At the same time, by integrating the signal conductive pin and the power conductive pin into one connector, the material processing, production assembly, electrical testing, and packaging costs can be reduced, and the circuit of the connector can be simpler and more optimized when it is applied to the product. In this embodiment, the first power conductive pin 111 and the first signal conductive pin 112 are respectively arranged on both sides of the plug board 250.
