Abstract
Description
Technical Field
[0001] This application relates to the technical field of connector sockets, and more particularly to a connector socket. Background Technology
[0002] With the widespread use of electric bicycles, the reliability of their internal circuit connections is becoming increasingly important for ensuring their normal operation. Stable circuit connections can not only ensure the accurate transmission of power output and control signals of electric bicycles, but also effectively reduce the probability of electrical faults, thereby improving the safety and user experience of electric bicycles.
[0003] Electric bicycles typically use male plugs and female sockets that interlock to connect the various key components inside the bicycle, enabling electrical conduction. In practical applications, the female socket is usually inserted into the circuit board inside the bicycle. However, in some rainy environments, such as those in southern regions, the tiny gap between the female socket and the circuit board can become a channel for rainwater to seep in. Rainwater seeping into the connection point through these gaps can cause the connection point to become damp or even accumulate water. This can not only affect the stable transmission of current and signals but also potentially lead to safety hazards. Summary of the Invention
[0004] To reduce the risk of rainwater seeping in through the gap between the female socket and the plug circuit board, a connector socket is provided.
[0005] The above-mentioned objective of this application is achieved through the following technical solution:
[0006] A connector socket includes a socket body for insertion onto a circuit board, a insertion groove on one side of the socket body, a plug body connected to a cable being inserted into the insertion groove, a mounting plate integrally formed on the outer wall of the socket body, and mounting holes on the four sides of the mounting plate; it also includes a sealing ring made of elastic material, the sealing ring being sleeved on the outer wall of the socket body and abutting against the mounting plate, and through holes on the four sides of the sealing ring corresponding to the mounting holes.
[0007] By adopting the above technical solution, during the installation of the socket body, the mounting plate needs to be inserted into the circuit board and connected to the circuit board by bolts passing through the mounting holes. The mounting plate forms a barrier between the outer wall of the socket body and the circuit board. At the same time, the sealing ring is fitted onto the outer wall of the socket body and abuts against the mounting plate. This can reduce the seepage of rainwater from the gap between the socket body and the mounting point, improve the sealing performance between the connector socket and the mounting point, ensure the reliability of the circuit connection, ensure the accurate transmission of power output and control signals of the electric vehicle, reduce the probability of electrical failures, and improve safety and user experience.
[0008] Preferably, the side of the sealing ring that abuts against the mounting plate is a flat surface, and the other side of the sealing ring is provided with a waterproof strip.
[0009] By adopting the above technical solution, one side of the sealing ring is flat to facilitate its fit with the mounting plate, and the other side is equipped with a waterproof strip to enhance the waterproof effect, reduce rainwater infiltration, and ensure the reliability of the internal circuit connection of the electric vehicle.
[0010] Preferably, the sealing ring has a waterproof protrusion on the side facing away from the mounting plate, which is coaxial with the perforation, and the diameter of the waterproof protrusion is larger than the diameter of the perforation.
[0011] By adopting the above technical solution, a waterproof protruding ring with a diameter larger than that of the perforation is set on the side of the sealing ring facing away from the mounting plate. During installation, the bolt passes through the perforation and mounting hole in sequence and is threaded to the circuit board. The diameter of the waterproof protruding ring is larger than that of the perforation. While the bolt fixes the mounting plate to the circuit board, the waterproof protruding ring can abut against and cover the bolt head, thereby reducing the risk of rainwater seeping in from the abutment point between the bolt and the sealing ring.
[0012] Preferably, the waterproof convex ring is raised away from the sealing ring.
[0013] By adopting the above technical solution, the raised structure gives the waterproof protrusion a pre-compressed elastic space. When the bolt passes through the through hole and the mounting hole and is fixed to the circuit board, the bolt will apply pressure to the sealing ring. The sealing ring and the waterproof protrusion will undergo progressive deformation, forming an adaptive fit with the bolt head. Compared with the planar structure, the raised design can compensate for a larger range of bolt tightening force differences.
[0014] Preferably, the socket body is fixedly provided with several positioning posts on the side away from the plug body.
[0015] By adopting the above technical solution, a positioning post is set at the other end of the socket body, which can play a positioning role during installation, improve the accuracy and efficiency of installation, and ensure the reliability of the internal circuit connection of the electric vehicle.
[0016] Preferably, the plug body has a plurality of elastic rubber rings on its outer periphery, and a rigid fixing strip is fixed on the inner wall of the insertion groove, the fixing strip being interference-slid into the gap between adjacent rubber rings.
[0017] By adopting the above technical solution, the plug body is inserted into the socket body's insertion groove. A rubber ring is set on the outer periphery of the plug body, and a fixing strip is set on the inner wall of the insertion groove, which is engaged with the gap between adjacent rubber rings. When the plug body and the socket body are plugged in, the cooperation between the fixing strip and the rubber ring can reduce the risk of rainwater seeping into the insertion groove from the outer wall of the plug body.
[0018] Preferably, the mounting plate has a fixing groove on the side facing the sealing ring, and the sealing ring has a rubber component embedded in the fixing groove on the side facing the mounting plate.
[0019] By adopting the above technical solution, the interference fit between the fixing groove and the rubber component can achieve precise positioning and stable connection between the sealing ring and the mounting plate, preventing the sealing ring from shifting or loosening during installation or use; at the same time, the elastic deformation of the rubber component can fill the gap in the fixing groove, further enhancing the sealing performance between the sealing ring and the mounting plate, effectively preventing rainwater from seeping in from the gaps at the contact surfaces, thereby improving the overall waterproof performance of the connector socket.
[0020] Preferably, a limiting strip is fixedly provided on the outer peripheral side wall of the socket body, and the limiting strip abuts against the waterproof strip.
[0021] By adopting the above technical solution, the limiting strip and the waterproof strip abut against each other, which can further prevent rainwater from seeping in from the gap between the sealing ring and the outer wall of the socket body, improve the waterproof performance of the connector socket, and ensure the reliability of the internal circuit connection of the electric vehicle.
[0022] Preferably, the diameter of the mounting hole is larger than the diameter of the through hole, and an integrally formed waterproof ring is provided on the side of the through hole facing the mounting hole. The waterproof ring is made of soft material, and the outer wall of the waterproof ring abuts against the inner wall of the mounting hole.
[0023] By adopting the above technical solution, when the mounting plate is installed on the circuit board, the bolt passes through the through hole and is threaded to the circuit board. One side of the waterproof column abuts against the bolt, and the other side of the waterproof column abuts against the inner wall of the mounting hole. This reduces the risk of rainwater seeping in through the gap between the mounting hole and the bolt in rainy weather, and ensures the reliability of the internal circuit connection of the electric vehicle.
[0024] Preferably, a sealing strip is provided on the inner wall of the mounting hole, and a sealing groove is opened on the outer wall of the waterproof ring for the sealing strip to slide into with interference fit.
[0025] By adopting the above technical solution, the waterproof ring inside the perforation abuts against the inner wall of the mounting hole to play a certain waterproof role, while the sealing strip on the inner wall of the mounting hole is engaged in the sealing groove on the outer wall of the waterproof ring, which can further enhance the waterproof effect, prevent rainwater from seeping into the connection between the connector socket and the circuit board, and ensure the reliability of the internal circuit connection of the electric vehicle.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. After the bolts pass through the through holes and mounting holes and are fixed to the circuit board, the elastic sealing ring is squeezed by the bolts, so that the waterproof convex ring can cover the head of the bolt for protection. The waterproof convex ring and the bolt head form a groove-type seal, covering the contact surface between the bolt and the through hole, preventing rainwater from seeping in along the bolt.
[0028] 2. The outer wall of the waterproof ring fits tightly against the inner wall of the mounting hole to form a radial seal, and the sealing strip is interference-fitted with the sealing groove on the outer wall of the waterproof ring to form an axial seal. The double sealing structure completely seals the water seepage channel between the mounting hole and the bolt, and can effectively waterproof even in high humidity or water splash environments.

[0036] The following section provides a more detailed description, in conjunction with the accompanying diagrams:
[0037] Example 1
[0038] As attached Figure 1 and attached Figure 2As shown, a connector socket includes a plug body 1 and a socket body 2. The plug body 1 includes a plug portion 11 and a locking portion 12. One side of the plug portion 11 is connected to a cable, and the other side of the plug portion 11 is engaged with the locking portion 12. The locking portion 12 and the plug portion 11 are engaged to form a plug interface 13. The socket body 2 is connected to a circuit board inside an electric vehicle battery. The socket body 2 is usually made of plastic material with good insulation properties, which has a certain strength and corrosion resistance. A plug groove 21 is opened on one side of the socket body 2. The plug groove 21 is used to engage with the plug body 1. The inner wall of the plug groove 21 is smooth and flat to ensure that the plug body 1 can be smoothly inserted and removed.
[0039] The outer periphery of the plug body 1 is fitted with several elastic rubber rings 14. The rubber rings 14 are fitted onto the outer wall of the plug part 11 and abut against the locking part 12. The rubber rings 14 can play a sealing and buffering role. An annular fixing strip 22 is fixed on the inner wall of the plug groove 21. The fixing strip 22 is engaged in the gap between adjacent rubber rings 14. When the plug body 1 is inserted into the plug groove 21 and plugged into the socket body 2, the fixing strip 22 slides into the gap between adjacent rubber rings 14 with interference fit. This can not only satisfy the limiting position between the plug body 1 and the socket body 2, but also reduce the risk of rainwater seeping into the plug groove 21 from the outer wall of the plug body 1.
[0040] Several positioning posts 23 are fixedly provided on the end of the socket body 2 away from the plug slot 21. The positioning posts 23 are generally cylindrical and play a positioning role when the socket body 2 is installed on the circuit board to ensure the accuracy of installation.
[0041] The socket body 2 is also provided with a socket terminal 24. One end of the socket terminal 24 is located in the insertion slot 21 and is inserted into the insertion interface 13. The other end of the socket terminal 24 extends to the outside of the socket body 2 and is inserted into the circuit board to realize the conduction of the circuit. The socket body 2 is filled with a filler to fix the socket terminal 24.
[0042] The socket body 2 is integrally formed with a mounting plate 3. The mounting plate 3 is made of rigid material. There are four mounting holes 31 on each of the four sides of the mounting plate 3. The inner wall of the mounting holes 31 is smooth and flat. When the socket body 2 is installed, the mounting holes 31 are used to fix the mounting plate 3 to the circuit board with bolts or other connectors. The mounting plate 3 has several fixing holes 32 on the side facing the circuit board. The fixing holes 32 are evenly spaced and arranged in an array. The setting of the fixing holes 32 can, on the one hand, allow some of the infiltrated rainwater to accumulate in the fixing holes 32, reducing the flow of rainwater on the back of the mounting plate 3. On the other hand, it can facilitate the fixing of the connector socket to other internal components of the electric vehicle, ensuring the stable installation of the connector socket.
[0043] As attached Figure 3As shown, a sealing ring 4 is also fitted around the outer periphery of the socket body 2. The sealing ring 4 is made of elastic rubber material, which has good elasticity and sealing performance. The inner wall of the sealing ring 4 abuts against the outer wall of the socket body 2. The sealing ring 4 abuts against the mounting plate 3. There are through holes 41 on the four sides of the sealing ring 4 that are aligned with the mounting holes 31. The diameter of the through holes 41 is equal to the diameter of the mounting holes 31. The side of the sealing ring 4 that abuts against the mounting plate 3 is flat, ensuring that the sealing ring 4 and the mounting plate 3 fit tightly and preventing rainwater from seeping in from the gap between them. A waterproof strip 42 is provided on the other side of the sealing ring 4. The waterproof strip 42 is raised and faces away from the sealing ring 4. The waterproof strip 42 can increase the resistance to rainwater flow and further prevent rainwater from seeping in.
[0044] A waterproof protruding ring 43, coaxial with the through hole 41, is provided on the side of the sealing ring 4 facing away from the mounting plate 3. The diameter of the waterproof protruding ring 43 is larger than the diameter of the through hole 41. The waterproof protruding ring 43 is raised away from the sealing ring 4. The surfaces of the waterproof protruding ring 43 and the sealing ring 4 form a groove 44 for the bolt head to be inserted and abutted. When the bolt passes through the through hole 41 and the mounting hole 31 and is connected to the circuit board, the bolt head is inserted and abutted in the groove 44. The bolt will exert a squeezing force on the sealing ring 4, which will simultaneously drive the raised part of the waterproof protruding ring 43 to cover the bolt head. The sealing ring 4 and the raised part of the waterproof protrusion undergo gradual deformation to form an adaptive fit with the bolt head, reducing the risk of rainwater seeping in from the contact between the bolt and the through hole 41.
[0045] The implementation principle of this first embodiment is as follows:
[0046] Mounting plate 3 is integrally formed on the outer periphery of socket body 2 and fits tightly with circuit board to form the first waterproof barrier. Sealing ring 4 is made of elastic material and its flat side fits tightly against mounting plate 3. Sealing ring 4 has a waterproof protrusion 43 coaxial with through hole 41 on the side facing away from mounting plate 3. After the bolt passes through through hole 41 and mounting hole 31 and is fixed to circuit board, the elastic sealing ring 4 is squeezed by the bolt, so that waterproof protrusion 43 can cover the head of bolt for protection. Waterproof protrusion 43 and bolt head form a groove 44 seal, covering the contact surface between bolt and through hole 41 to prevent rainwater from seeping in along bolt.
[0047] Example 2
[0048] The structure of this second embodiment is an improvement on the first embodiment. All other structures are the same as those in the first embodiment, and will not be described in detail here.
[0049] As attached Figure 4As shown, a limiting strip 25 is fixed on the outer wall of the socket body 2. The limiting strip 25 is made of rigid material and is set to abut against the waterproof strip 42. The limiting strip 25 can limit the position of the sealing ring 4 on the mounting plate 3 to prevent rainwater from seeping in due to displacement of the sealing ring 4 during use.
[0050] As attached Figure 5 and attached Figure 6 As shown, a rubber component 45 is integrally formed on the side of the sealing ring 4 facing the mounting plate 3. There are four rubber components 45 here, located on both sides of the sealing ring 4. The rubber components 45 are made of elastic rubber. Each end of the rubber component 45 includes a round rod portion 451 and a limiting portion 452. The round rod portion 451 is fixedly connected to the side of the sealing ring 4 facing the mounting plate 3. The limiting portion 452 is conical in shape, with a rounded surface on the side facing the sealing ring 4 and a chamfer on the side facing away from the sealing ring 4. The diameter of part 452 facing the sealing ring 4 is larger than the diameter of the round rod part 451. The mounting plate 3 has a fixing groove 33 on the side facing the sealing ring 4 for the rubber part 45 to be interference-fitted. The shape of the fixing groove 33 is adapted to the rubber part 45. Through the interference fit between the fixing groove 33 and the rubber part 45, the sealing ring 4 and the mounting plate 3 can be accurately positioned and firmly connected. The elastic deformation of the rubber part 45 can fill the gap in the fixing groove 33, further enhancing the sealing performance between the sealing ring 4 and the mounting plate 3, and effectively preventing rainwater from seeping in from the gaps at the contact surfaces.
[0051] The diameter of the mounting hole 31 is larger than the diameter of the through hole 41. A waterproof ring 5 is integrally formed on the outer wall of the through hole 41 facing the mounting hole 31. The waterproof ring 5 is inserted into the mounting hole 31, and the outer wall of the waterproof ring 5 abuts against the inner wall of the mounting hole 31. The middle of the waterproof ring 5 can be used for bolts to pass through, and a sealing groove 51 is opened on the outer wall of the waterproof ring 5. A sealing strip 34 is provided on the inner wall of the mounting hole 31 to engage with the sealing groove 51. Here, two sealing strips 34 are provided in a single mounting hole 31. The cooperation between the sealing strip 34 and the sealing groove 51 can prevent rainwater from seeping into the circuit board from the inner wall of the mounting hole 31.
[0052] The implementation principle of this second embodiment:
[0053] The waterproof ring 5 is integrally formed with the outer wall of the perforation 41. The outer wall of the waterproof ring 5 fits tightly with the inner wall of the mounting hole 31 to form a radial seal. A sealing strip 34 is added to the inner wall of the mounting hole 31. The sealing strip 34 is interference-fitted with the sealing groove 51 on the outer wall of the waterproof ring 5 to form an axial seal. The double sealing structure completely seals the water seepage channel between the mounting hole 31 and the bolt, and can effectively waterproof even in high humidity or water splash environments.
[0054] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
