Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to a quick-connect waterproof cable connector. Background Technology

[0002] A cable connector is an electrical connection device used to connect two or more circuit conductors, or to connect transmission elements and equipment, thereby enabling the transmission of current or signals. It provides a separable interface for the circuit, ensuring that current or signals flow smoothly at circuit breaks or between independent circuits, without negatively impacting system performance.

[0003] Traditional cable connectors lack protective structures at the joints, making them susceptible to damage from moisture, dust, and other impurities over time. This can lead to damage to internal electronic components and precision parts, affecting the normal operation of the equipment.

[0004] Therefore, those skilled in the art have provided a quick-connect waterproof cable connector to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-connect waterproof cable connector. When the connecting ring is pushed into the slot, the protrusion is squeezed into the cavity until the connecting ring is fully embedded. The spring force causes the protrusion to pop out and engage with the slot. The connection between the first and second connecting blocks is sealed by the first and second rubber rings, effectively preventing moisture, dust and other impurities from entering the equipment and protecting the internal electronic components, thereby enhancing waterproof performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-connect waterproof cable connector includes a first connecting block and a second connecting block. A sealing mechanism is provided on the outer walls of the first and second connecting blocks. The sealing mechanism includes a connecting ring. One side of the connecting ring is fixedly connected to the other side of the first connecting block. Cavities are evenly distributed along the edge of the inner wall of the connecting ring. A spring is fixedly connected to one end of each cavity near the center of the connecting ring, and a protrusion is fixedly connected to one end of each spring away from the center of the connecting ring. A slot is provided on one side of the second connecting block. A threaded sleeve is fitted onto the outer walls of the first and second connecting blocks. A first rubber ring is fixedly connected to both sides of the threaded sleeve. A second rubber ring is provided on the inner wall of the other side of the second connecting block.

[0008] The connecting ring is pushed into the slot using the above technical solution. During the pushing process, the protrusion on the connecting ring is squeezed by the inner wall of the slot and gradually enters the cavity until the connecting ring is completely inside the slot. The pre-compressed spring will then play its role, and its elasticity will cause the protrusion to pop out of the cavity and firmly engage with the internal structure of the slot. The first and second rubber rings can seal the connection between the first and second connecting blocks, which can effectively prevent moisture, dust and other impurities from entering the equipment and protect the internal electronic components and parts.

[0009] Furthermore, both the first connecting block and the second connecting block have external threads on the side near the center of the first connecting block;

[0010] The above technical solution enables the first connecting block and the second connecting block to engage with each other through threaded sleeves, thereby enhancing the stability and pull-out resistance of the connection.

[0011] Furthermore, the outer wall of the threaded sleeve is provided with an electroplated layer, and the outer wall of the electroplated layer is provided with a chemical conversion film;

[0012] Through the above technical solutions, the electroplated layer has a certain degree of corrosion resistance, and the chemical conversion film further enhances the corrosion resistance, enabling it to improve the wear resistance of the outer wall of the threaded sleeve and extend its service life.

[0013] Furthermore, a plug is provided on the other side of the first connecting block, and the plug engages with the second connecting block;

[0014] With the above technical solution, the locking structure can be easily disassembled and reassembled when maintenance or replacement is required, making it easy to operate.

[0015] Furthermore, a cable body is provided on the inner wall of the other side of the electric second connecting block;

[0016] The above technical solutions can reduce additional cable fixing components or connectors, simplify the overall structure, and reduce manufacturing costs and assembly complexity.

[0017] Furthermore, all of the aforementioned protrusions slide on the inner wall of the cavity;

[0018] Through the above technical solution, the combined action of multiple protrusions can distribute the engaging force to multiple contact points, ensuring accurate docking between the connecting ring and the slot, and improving the reliability and stability of the connection.

[0019] Furthermore, all of the aforementioned protrusions engage with the slots;

[0020] The above technical solution forms a tight seal, and the first and second rubber rings further enhance the waterproof performance of the connection and prevent liquid intrusion.

[0021] Furthermore, the external thread is threadedly connected to the inner wall of the threaded sleeve;

[0022] Through the above technical solutions, threaded connection is a mature connection method with reliable connection performance. It can ensure the stability of the connection, reduce the risk of loosening caused by vibration, impact and other factors, and improve the reliability of the connection.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a quick-connect waterproof cable connector. When the connecting ring is pushed into the slot, the protrusion on the connecting ring is squeezed by the inner wall of the slot during the pushing process, and gradually enters the cavity until the connecting ring is completely in the slot. The pre-compressed spring will then play its role, and its elasticity will cause the protrusion to pop out of the cavity and firmly engage with the internal structure of the slot. The first rubber ring and the second rubber ring can seal the connection between the first connecting block and the second connecting block, which can effectively prevent moisture, dust and other impurities from entering the equipment, protect the internal electronic components and parts, ensure their normal operation, and enhance waterproof performance.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a specific embodiment of a quick-connect waterproof cable connector, comprising a first connecting block 2 and a second connecting block 3. A sealing mechanism 1 is provided on the outer wall of the first connecting block 2 and the second connecting block 3. The sealing mechanism 1 includes a connecting ring 101. One side of the connecting ring 101 is fixedly connected to the other side of the first connecting block 2. Holes 102 are evenly opened at the edge of the inner wall of the connecting ring 101. A spring 103 is fixedly connected to one end of each cavity 102 near the center of the connecting ring 101. A protrusion 104 is fixedly connected to one end of each spring 103 away from the center of the connecting ring 101. A slot 105 is opened on one side of the second connecting block 3. A threaded sleeve 4 is fitted on the outer wall of the first connecting block 2 and the second connecting block 3. A first rubber ring 106 is fixedly connected to both sides of the threaded sleeve 4. A second rubber ring 107 is provided on the inner wall of the other side of the second connecting block 3.

[0037] When the connecting ring 101 is pushed into the slot 105, the protrusion 104 on the connecting ring 101 will be squeezed by the inner wall of the slot 105 and gradually enter the cavity 102 until the connecting ring 101 is completely in the slot 105. The pre-compressed spring 103 will then play its role, and its elasticity will cause the protrusion 104 to pop out from the cavity 102 and firmly engage with the internal structure of the slot 105. The first rubber ring 106 and the second rubber ring 107 can seal the connection between the first connecting block 2 and the second connecting block 3, which can effectively prevent moisture, dust and other impurities from entering the equipment and protect the internal electronic components and parts.

[0038] Reference Figure 5 , Figure 6 and Figure 7Both the first connecting block 2 and the second connecting block 3 have external threads 7 on one side near the center of the first connecting block 2, so that the first connecting block 2 and the second connecting block 3 can be engaged with the threaded sleeve 4, which enhances the stability of the connection and the pull-out resistance. The outer wall of the threaded sleeve 4 is covered with an electroplated layer 5, and the outer wall of the electroplated layer 5 is covered with a chemical conversion film 6. The electroplated layer 5 has a certain corrosion resistance, and the chemical conversion film 6 further enhances the corrosion resistance, which can improve the wear resistance of the outer wall of the threaded sleeve 4 and extend its service life. The other side of the first connecting block 2 is provided with a plug 9, which engages with the second connecting block 3.

[0039] When maintenance or replacement is required, the engaging structure can be easily disassembled and reassembled, facilitating operation. The cable body 8 is provided on the inner wall of the other side of the electric second connecting block 3, which can reduce additional cable fixing parts or connectors, simplify the overall structure, reduce manufacturing costs and assembly complexity. Multiple protrusions 104 slide on the inner wall of the cavity 102. The multiple protrusions 104 work together to distribute the engaging force to multiple contact points, ensuring accurate docking between the connecting ring 101 and the slot 105, improving the reliability and stability of the connection. Multiple protrusions 104 engage with the slot 105 to form a tight seal. The first rubber ring 106 and the second rubber ring 107 provided can further enhance the waterproof performance of the connection and prevent liquid intrusion. The external thread 7 is threaded to the inner wall of the threaded sleeve 4. Threaded connection is a mature connection method with reliable connection performance, which can ensure the stability of the connection, reduce the risk of loosening caused by vibration, impact and other factors, and improve the reliability of the connection.

[0040] Working principle: When the connecting ring 101 is pushed into the slot 105, the protrusion 104 on the connecting ring 101 is squeezed by the inner wall of the slot 105 and gradually enters the cavity 102 until the connecting ring 101 is completely in the slot 105. The pre-compressed spring 103 will then play its role, and its elasticity will cause the protrusion 104 to pop out from the cavity 102 and firmly engage with the internal structure of the slot 105. Then, the threaded sleeve 4 is connected to the external thread 7. When disassembling, the threaded sleeve 4 is disconnected from the external thread 7. Then, the first connecting block 2 is rotated to rotate the protrusion 104 to the reserved slot. Then, the connecting ring 101 is taken out and disassembled. The first rubber ring 106 and the second rubber ring 107 ensure that the connection between the first connecting block 2 and the second connecting block 3 is sealed, thereby enhancing its waterproof performance.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
