Description

Technical Field

[0001] This invention relates to the field of waterproof joint technology, and more specifically to the structure of a waterproof joint. Background Technology

[0002] Currently, signal lines or power lines are connected in many places. Different types of connectors are used for different usage environments. When signal lines or power lines are used underwater or in humid environments for a long time, special waterproof connectors are usually used.

[0003] Most waterproof connectors on the market use a nut and rubber ring compression method for waterproofing. This structure requires tightening the nut multiple times during installation, which is relatively cumbersome and time-consuming. This significantly impacts efficiency when installing in large quantities. In addition, whether the nut is tightened properly is affected by factors such as temperature and the strength of the operator, making it difficult to have standardized indicators. As a result, the final waterproof effect is not very stable. Overall, it still has certain shortcomings. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a structure for a waterproof connector to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a waterproof connector structure, comprising: a connector, one end of which is provided with a first connection point, and an external wire can be connected to the first connection point to achieve electrical conductivity with the connector; a connector base, the end of which is provided with a locking part, the shape of which corresponds to the end of the connector head away from the first connection point, and the end of the connector head away from the first connection point can be combined with the connector base through the locking part, and after the connector head and the connector base are combined through the locking part, the connector head and the connector base are electrically conductive, and the end of the connector base away from the locking part is provided with a second connection point, and an external wire can be connected to the second connection point to achieve electrical conductivity with the connector base; and a sealing component, which can be sleeved on the connection part of the connector head and the connector base from the end of the connector head and the connector base away from the locking part, and seal and wrap the connection part of the connector head and the connector base.

[0006] Furthermore, after the sealing component is fitted onto the connection between the connector and the connector seat, it limits the degree of freedom of movement of the connector along its own axial direction.

[0007] Furthermore, the sealing assembly includes a sealing sleeve, a sealing ring, and a limiting member. The size of the sealing sleeve corresponds to that of the connector and the connecting seat, and the sealing sleeve can be fitted onto the connection part of the connector and the connecting seat from the end of the connector and the connecting seat away from the engaging part. The surfaces of the connector and the connecting seat are provided with mounting grooves, and the sealing ring is detachably embedded in the mounting grooves. After the sealing sleeve is fitted onto the connection part of the connector and the connecting seat, the sealing sleeve presses against the sealing ring and achieves a seal at the connection part of the connector and the connecting seat. The limiting member is adapted to the sealing sleeve, and after the sealing sleeve is fitted onto the connection part of the connector and the connecting seat, the limiting member can axially limit the sealing sleeve.

[0008] Furthermore, the limiting component includes a fixed stop, a slot, and a movable stop. The fixed stop and the slot are respectively disposed at both ends of the sealing sleeve. The fixed stop is fastened to the side of the connection between the connector and the connecting seat. The slot is opened on the upper surface of the connection between the connector and the connecting seat. The movable stop can be inserted into the slot and block the end of the sealing sleeve away from the fixed stop.

[0009] Furthermore, the fixing stop is fixedly installed on the surface of the connector, and the slot is opened on the surface of the connector seat.

[0010] Furthermore, the fixing stop is fixedly installed on the surface of the connector, and the slot is opened on the surface of the connector.

[0011] Furthermore, the movable stop is flat and has a hole in the middle. At the same time, the edge of the movable stop has a notch that extends into the hole. Both sides of the movable stop at the notch can be elastically deformed. The movable stop can align the notch with the slot and apply force to make it elastically deformed to be inserted into the slot.

[0012] Furthermore, the movable stop and the sealing sleeve are separate structures, and when the sealing sleeve comes into contact with the fixed stop, the movable stop can be inserted into the slot and abut against the sealing sleeve.

[0013] Furthermore, the movable stop and the sealing sleeve are partially fixedly connected to each other, and when the connection between the connector and the connecting seat on the sealing sleeve is pressed tightly against the fixed stop, the movable stop will open and be inserted into the slot.

[0014] Furthermore, the end of the connector and connector assembly that is away from the fixed stop is tapered, and the narrow end is away from the fixed stop.

[0015] The technical effects and advantages of this invention are as follows:

[0016] This invention, by setting a sealing component, ensures a sealing effect between the connector and the connector seat by sliding it onto the surface of the connection area. During installation, only the single sliding sealing component needs to be slid, eliminating the need for excessive threading, effectively simplifying the operation process, thereby improving installation efficiency and making it convenient to use. In addition, during use, after the sealing component is fully fitted onto the connection area of ​​the connector and the connector seat, it will automatically limit its own axial movement, which further simplifies the operation process.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative and are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figure 1-7 This invention provides a waterproof connector structure, including: a connector 100, a connector 200, and a sealing assembly 300. One end of the connector 100 has a first connection point 110, and an external wire can be connected to the first connection point 110 to achieve electrical conductivity with the connector 100. The connector 200 has a locking portion at its end, the shape of which corresponds to the end of the connector 100 away from the first connection point 110. The end of the connector 100 away from the first connection point 110 can be combined with the connector 200 through the locking portion. After the connector 100 and the connector 200 are combined through the locking portion, the connector 100 and the connector 200 are connected... The connector 200 is electrically conductive. The end of the connector 200 away from the engaging part is provided with a second connection point 210. An external wire can be connected to the second connection point 210 to achieve electrical conductivity with the connector 200. The sealing component 300 can be sleeved on the connection part of the connector 100 and the connector 200 from the end of the assembly of the connector 100 and the connector 200 away from the engaging part, and seals the connection part of the connector 100 and the connector 200. At the same time, after the sealing component 300 is sleeved on the connection part of the connector 100 and the connector 200, it will limit the degree of freedom of movement of the connector 100 along its own axial direction.

[0028] The connector 100 has a first connecting post 120 installed at the end away from the connector seat 200. A first threaded sleeve 130 is threaded onto the surface of the first connecting post 120. A first connection point 110 is located at the end of the first connecting post 120. After the external wire is connected to the first connection point 110, glue can be injected from the opening end of the first threaded sleeve 130 away from the first connecting post 120 to seal the external wire with the first connection point 110. The connector seat 200 has a second connecting post 220 fixedly installed at the end away from the connector 100. A second connection point 210 is fixedly installed at the end of the second connecting post 220. A second threaded sleeve 230 is threaded onto the surface of the second connecting post 220. Glue can be injected from the opening of the second threaded sleeve 230 away from the second connecting post 220 to seal the external glue with the second connection point 210.

[0029] Thus, simply connect the two wires to the first connection point 110 and the second connection point 210 respectively, then screw the first threaded sleeve 130 and the second threaded sleeve 230 onto the first connecting post 120 and the second connecting post 220 respectively. After that, pour glue into the open ends of the first threaded sleeve 130 and the second threaded sleeve 230 respectively. After the glue solidifies, the wires can be sealed together with the first connection point 110 and the second connection point 210 respectively. After the above steps are completed, the connector 100 and the connector 200 can be combined together by the locking part to make the wires at both ends electrically conductive. Then, simply put the sealing component 300 on the surface of the connection part of the connector 100 and the connector 200 to seal the connection part of the connector 100 and the connector 200, thereby achieving a waterproof connection.

[0030] The sealing assembly 300 includes a sealing sleeve 310, a sealing ring 320, and a limiting member 330. The size of the sealing sleeve 310 corresponds to that of the connector 100 and the connector 200. The sealing sleeve 310 can be sleeved on the connection part of the connector 100 and the connector 200 from the end of the assembly away from the engaging part. The surfaces of the connector 100 and the connector 200 are provided with mounting grooves 340. The sealing ring 320 is detachably embedded in the mounting groove 340. After the sealing sleeve 310 is sleeved on the connection part of the connector 100 and the connector 200, the sealing sleeve 310 presses the sealing ring 320 and achieves a seal at the connection part of the connector 100 and the connector 200.

[0031] Thus, by simply placing the sealing ring 320 into the mounting groove 340 on the connector 100 and the connector 200 beforehand, and then putting the sealing sleeve 310 onto the surface of the connection part of the assembled connector 100 and connector 200, the sealing sleeve 310 will press the sealing ring 320 together, thereby forming a sealing effect.

[0032] The limiting member 330 is adapted to the sealing sleeve 310. After the sealing sleeve 310 is fitted onto the connection part between the connector 100 and the connecting seat 200, the limiting member 330 can axially limit the sealing sleeve 310, thus preventing the sealing sleeve 310 from shifting and causing sealing failure.

[0033] Specifically, the limiting member 330 includes a fixed stop member 331, a slot 332, and a movable stop member 333. The fixed stop member 331 and the slot 332 are respectively disposed at both ends of the sealing sleeve 310. The fixed stop member 331 is fastened to the side of the connection part between the connector 100 and the connecting seat 200. The slot 332 is opened on the upper surface of the connection part between the connector 100 and the connecting seat 200. The movable stop member 333 can be inserted into the slot 332 and block the end of the sealing sleeve 310 away from the fixed stop member 331.

[0034] Thus, after the sealing sleeve 310 is fitted onto the connection between the connector 100 and the connector 200, one end of the sealing sleeve 310 only needs to be tightly pressed against the fixed stop 331, and then the movable stop 333 is inserted into the slot 332 to limit the other end of the sealing sleeve 310, thereby simultaneously limiting both ends of the sealing sleeve 310, thus preventing the sealing sleeve from shifting.

[0035] In this application, the fixing stop 331 is preferably a ring whose size corresponds to the sealing sleeve 310 and can abut against the sealing sleeve 310.

[0036] There are two possible positions for the fixing abutment 331 and the slot 332. The accompanying drawings of this invention only show the first case. In the first case, the fixing abutment 331 is fixedly installed on the surface of the connector 100, and the slot 332 is opened on the surface of the connector 200. In the second case, the fixing abutment 331 is fixedly installed on the surface of the connector 200, and the slot 332 is opened on the surface of the connector 100. Both of these structures can achieve the fixing of the sealing sleeve 310. In specific implementation, the choice can be made freely according to the requirements.

[0037] The movable stop 333 is flat and has a hole 334 in the middle. The edge of the movable stop 333 has a notch 335 that extends into the hole 334. Both sides of the movable stop 333 at the notch 335 can be elastically deformed. The movable stop 333 can align the notch 335 with the slot 332 and apply force to make it elastically deform and lock into the slot 332.

[0038] Thus, when installing the movable stop 333, two structures can be designed. The first is that the movable stop 333 and the sealing sleeve 310 are separate structures (e.g., Figure 1 , Figure 2 and Figure 3 As shown), when the sealing sleeve 310 contacts the fixed stop 331, the movable stop 333 can be inserted into the slot 332 and abut against the sealing sleeve 310. This structure is relatively simple and reliable. The installation of the movable stop 333 is relatively simple, but the installation of the sealing assembly 300 needs to be carried out in two steps.

[0039] The second type is where the movable stopper 333 and the sealing sleeve 310 are partially fixedly connected to each other (e.g., Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the diagram, when the sealing sleeve 310 is fitted onto the connection between the connector 100 and the connecting seat 200 until its end is tightly against the fixed stop 331, it will cause the movable stop 333 to open and be inserted into the slot 332. In this way, when the sealing sleeve 310 slides onto the connector 100 and the connecting seat 200, it will simultaneously drive the movable stop 333 to move. During this process, the connecting seat 200 or the connector 100 will first push the movable stop 333 open from the hole 334 and the notch 335 to make it elastically deformed. Thus, when the movable stop 333 slides onto the slot 332, its own elastic potential energy will be released, thereby being inserted into the slot 332. Under this structure, the installation of the sealing assembly 300 only requires one step, but the partial fixation of the movable stop 333 and the sealing sleeve 310 requires a more complex process. In actual implementation, the choice can be made according to the requirements.

[0040] It should be noted that the end of the connector 100 and the connector 200 that is away from the fixed stop 331 is tapered, and the narrow end is away from the fixed stop 331. In this way, when the movable stop 333 slides into the connector 100 or the connector 200 along with the sealing sleeve 310, the narrower end of the connector 100 or the connector 200 can more easily enter the hole 334 to open the movable stop 333, thereby facilitating installation.

[0041] In the above solution, the movable stop 333 is engaged with the slot 332 to limit the sealing sleeve 310 and ensure sealing stability. With this structure, when the entire waterproof connector is used in a low-temperature environment, it is affected by thermal expansion and contraction. Gaps may appear between the sealing sleeve 310 and the fixed stop 331, between the sealing sleeve 310 and the movable stop 333, and between the movable stop 333 and the slot 332, making the sealing sleeve 310 prone to loosening. This could potentially weaken the sealing effect or even cause it to fail. Further optimization is needed, as follows:

[0042] like Figure 6 and Figure 7 As shown, a guide ring 337 is fixedly installed in the slot 332. When the movable stop 333 is inserted into the slot 332, the inner ring surface of the hole 334 on it will contact the guide ring 337. At this time, the contact surface between the inner ring surface of the hole 334 and the guide ring 337 is processed into a slope. This slope can convert the elastic potential energy of the movable stop 333 into a thrust that moves the movable stop 333 toward the sealing sleeve 310.

[0043] In this way, when a gap is created between the sealing sleeve 310 and the surrounding parts, the sealing sleeve 310 can be pushed to continue moving until it contacts and is fixed with the fixed stop 331, thereby effectively ensuring the sealing effect and improving the waterproof stability of the entire waterproof joint.

[0044] Therefore, the complete usage process is as follows: First, connect the two wires to be connected to the first connection point 110 and the second connection point 210 respectively. Then, screw the first threaded sleeve 130 and the second threaded sleeve 230 onto the first connecting post 120 and the second connecting post 220 respectively. Next, pour glue into the open ends of the first threaded sleeve 130 and the second threaded sleeve 230 respectively. After the glue solidifies, the wires can be sealed together with the first connection point 110 and the second connection point 210 respectively. Then, assemble the connector 100 and the connector 200 together through the engaging part to make the two wires electrically conductive. The sealing ring 320 needs to be fitted onto the connector 100 and the connector 200 beforehand. After completing the above steps, place the sealing sleeve 310 onto the surface of the connection between the assembled connector 100 and the connector 200 in the mounting groove 340 on the 0. (It is best to install the first threaded sleeve 130 or the second threaded sleeve 230 after the sealing sleeve 310 is in place to avoid the sealing sleeve 310 being unable to be installed due to the influence of the first threaded sleeve 130 or the second threaded sleeve 230). The sealing sleeve 310 will then press against the sealing ring 320 to form a sealing effect. During this process, the sealing sleeve 310 needs to slide until it is in close contact with the fixed stop 331. Then, the movable stop 333 is inserted into the slot 332 to limit the sealing sleeve 310, thereby ensuring the stability of the waterproof effect.

[0045] In summary, throughout the entire usage process, the sealing component 300 is directly slidably fitted onto the surface of the connection between the connector 100 and the connector 200, thereby ensuring the sealing effect between the two. During installation, only the sealing component 300 needs to be slidably moved, without the need for excessive threading, which effectively simplifies the operation process, thereby improving installation efficiency and making it convenient to use.

[0046] In addition, during use, after the sealing component 300 completely covers the connection between the connector 100 and the connector 200, it will automatically limit its own axial movement, which further simplifies the operation process.

[0047] Another option for the limiting component 330 is as follows: The limiting component 330 includes several blocks 338 and bayonet 339. The blocks 338 are fixed to the combined connector 100 and connector 200. The bayonet 339 is opened at the end of the sealing sleeve 310 and can be elastically deformed and opened. When the sealing sleeve 310 slides onto the combined connector 100 and connector 200, the bayonet 339 will first open under the action of the blocks 338 and then lock onto the blocks 338. At the same time, after the bayonet 339 and the blocks 338 are engaged, the axial movement of the sealing sleeve 310 will be limited.

[0048] The stop block 338 can be fixedly installed on the connector 100 or the connector 200. If it is installed on the connector 100, the sealing sleeve 310 is inserted from the end of the connector 200. If it is installed on the connector 200, it is inserted from the end of the connector 100.

[0049] Thus, when the sealing sleeve 310 is slidably fitted onto the assembled connector 100 and connector 200, it is only necessary to align the latch 339 with the latch block 338. Then, when the sealing sleeve 310 slides to contact the latch block 338, the latch 339 will be opened by the latch block 338 and locked onto the latch block 338. At this time, the axial movement of the sealing sleeve 310 will be directly limited, and the connector 100 and connector 200 will be prevented from separating.
