Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically to an anti-loosening connector. Background Technology
[0002] A connector is an electrical connector used to connect two active devices to transmit current or signals. Like a bridge, it establishes a communication channel between blocked or isolated parts of a circuit, allowing current or signals to flow smoothly and enabling the device to perform its intended function.
[0003] Currently, some connectors use plug-in connections. During equipment operation, the continuous vibration can easily cause slight displacement of the male and female connection parts of the connector. After long-term use, the connection may become loose, which not only affects the stable transmission of signals or current, but may also cause equipment failure or even safety accidents. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-loosening connector to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: an anti-loosening connector, including a female connector and a male connector, which cooperate to form a connector. The outer circumferential wall of the male connector is slidably connected with a threaded cap. When the male connector is inserted into the female connector, the threaded cap cooperates with the threaded groove on the outer circumferential wall of the female connector to fix the male connector. Two symmetrically distributed elastic plates are rotatably connected to one side of the threaded cap, and a plug is rotatably connected to the other end of the elastic plates. A retaining cap is integrally formed on the outer circumferential wall of the male connector. One end of the retaining cap is open, and the plug is inserted into the gap formed between the opening of the retaining cap and the male connector. A retaining groove is opened on the outer circumferential wall of the male connector. When the plug is inserted into the gap, the elastic plate is squeezed into an arc shape and located in the retaining groove.
[0006] As a further improvement of this utility model, rubber pads are glued to the upper and lower sides of the insert block.
[0007] As a further embodiment of this utility model, a rubber ring is provided on one side of the female connector. When the threaded cap is fixed to the female connector, the rubber ring squeezes and pushes the threaded cap to move towards the locking cap.
[0008] As a further embodiment of this utility model, the outer circumferential wall of the female connector is integrally formed with a fixing ring, and the outer circumferential wall of the female connector is threaded with a nut. The nut cooperates with the fixing ring to fix the female connector to an external device.
[0009] As a further embodiment of this invention, a washer is provided between the nut and the external device to increase the friction between the nut and the external device.
[0010] As a further embodiment of this invention, the elastic plate is a spring steel plate.
[0011] As a further embodiment of this invention, the side of the rubber ring facing the threaded cap is inclined.
[0012] As a further embodiment of this invention, the rubber ring expands after being squeezed by the threaded cap and then covers the threaded cap.
[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model uses an elastic plate in conjunction with a threaded cap to apply a force that pushes the threaded cap toward the female connector. This force can effectively counteract the loosening tendency of the threaded connection caused by vibration, temperature changes and other factors during long-term use, and enhance the tightness of the connection between the threaded cap and the female connector.
[0014] 2. The inclined surface design of this utility model allows the rubber ring to expand outward more smoothly when squeezed by the threaded cap, forming a wrapping contact, increasing the friction between the threaded cap and the female connector, and helping to resist the loosening tendency of the threaded connection. At the same time, the elastic recovery force of the rubber ring itself will continue to act on the threaded cap, ensuring stable pressure at the thread engagement point, thus significantly enhancing the anti-loosening effect.
[0015] 3. This utility model effectively prevents the threaded cap from loosening due to vibration or external force through a double anti-loosening design, significantly improving the overall anti-loosening performance of the connector and ensuring the stability and reliability of the connection between the female connector and the female connector.

[0021] The technical solution of this utility model 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. This utility model is 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 this utility model.
[0022] Reference Figures 1-4 This utility model provides an anti-loosening connector, including a female connector 1 and a female connector 2. The female connector 1 and the female connector 2 cooperate to form a connector. A threaded cap 7 is slidably connected to the outer circumference of the female connector 2. When the female connector 2 is inserted into the female connector 1, the threaded cap 7 cooperates with the threaded groove on the outer circumference of the female connector 1 to fix the female connector 2. Two symmetrically distributed elastic plates 11 are rotatably connected to one side of the threaded cap 7. A plug 10 is rotatably connected to the other end of the elastic plate 11. A retaining cap 8 is integrally formed on the outer circumference of the female connector 2. One end of the retaining cap 8 is open, and the plug 10 is inserted into the gap formed between the opening of the retaining cap 8 and the female connector 2. A retaining groove 9 is opened on the outer circumference of the female connector 2. When the plug 10 is inserted into the gap, the elastic plate 11 is squeezed into an arc shape and located in the retaining groove 9. A rubber ring 6 is provided on one side of the female connector 1. When the threaded cap 7 is fixed to the female connector 1, the rubber ring 6 squeezes and pushes the threaded cap 7 to move towards the retaining cap 8. After the female connector 2 is inserted into the female connector 1, firstly, rotate the threaded cap 7 to move it along the outer wall of the female connector 2 toward the female connector 1. At this time, the thread on the inner wall of the threaded cap 7 gradually engages with the thread groove on the outer wall of the female connector 1. As the threaded cap 7 is continuously tightened, the female connector 2 is stably pulled into the female connector 1 and initially fixed. Then, insert block 10 is inserted into the gap. At this time, under the action of cap 8 and thread cap 7, the elastic plate 11 is squeezed and deformed, thereby applying a force to push thread cap 7 to move towards female connector 1. This force can effectively counteract the loosening tendency of threaded connection caused by vibration, temperature change and other factors during long-term use, and further enhance the connection tightness between thread cap 7 and female connector 1. At the same time, after the elastic plate 11 is bent, it is inserted into the slot 9, but it does not fit against the bottom inner wall of the slot 9 (the left and right sides of the slot 9 limit the elastic plate 11). This not only provides a stable deformation space for the elastic plate 11, but also forms a radial limit on it, so as to prevent the elastic plate 11 from shifting when subjected to force and affecting the anti-loosening effect. In addition, the rubber ring 6 on one side of the female connector 1 is continuously squeezed during the tightening of the threaded cap 7. The reaction force generated by this compression will push the threaded cap 7 towards the locking cap 8, making the threaded cap 7 and the thread of the female connector 1 more tightly engaged. Combined with the pushing force of the elastic plate 11 on the threaded cap 7, a double anti-loosening guarantee is formed, which effectively prevents the threaded cap 7 from loosening due to vibration or external force, significantly improving the overall anti-loosening performance of the connector and ensuring the stability and reliability of the connection between the female connector 1 and the female connector 2.
[0023] It should be noted that: the elastic plate 11 is made of spring steel, which has good elastic deformation capacity and restoring performance. It can maintain stable mechanical properties after repeated compression and bending, ensuring the effectiveness of the anti-loosening structure during long-term use; The depth and width of the slot 9 are precisely calculated to provide sufficient space for the elastic plate 11, and the limiting effect on the left and right sides ensures that the elastic plate 11 is always kept in the preset force direction, preventing it from failing due to radial displacement.
[0024] In this utility model, rubber pads 12 are respectively glued to the upper and lower sides of the plug 10. These rubber pads 12 can fill the tiny gap between the plug 10 and the inner wall of the gap when the plug 10 is inserted into the gap between the opening of the cap 8 and the sub-connector 2, increase the friction between the plug 10 and the cap 8 and the sub-connector 2, thereby further preventing the plug 10 from accidentally coming out of the gap due to vibration and other factors during the use of the connector, ensuring that the elastic plate 11 can always apply a stable thrust to the threaded cap 7, and ensuring the continuous effectiveness of the double anti-loosening guarantee; Meanwhile, the rubber pad 12 also acts as a buffer, reducing the hard collision between the insert 10 and the cap 8 and sub-connector 2 when the insert 10 is inserted or subjected to external impact, thus preventing the components from being damaged due to long-term friction or impact and extending the service life of the connector.
[0025] Furthermore, the outer circumferential wall of the female connector 1 is integrally formed with a retaining ring 3, and the outer circumferential wall of the female connector 1 is threaded with a nut 5. The nut 5 cooperates with the retaining ring 3 to fix the female connector 1 to the external equipment. During installation, first pass the female connector 1 through the mounting hole of the external equipment, so that the retaining ring 3 is tightly against the outer wall of the equipment. Then rotate the nut 5 to move it along the outer wall of the female connector 1 towards the retaining ring 3. As the nut 5 is tightened, it and the retaining ring 3 together form a clamping force on the edge of the mounting hole of the external equipment, thereby firmly fixing the female connector 1 to the equipment. This effectively prevents the female connector 1 from shifting or loosening due to vibration or other factors during use, and provides basic support for the stable connection between the female connector 2 and the female connector 1.
[0026] Among them, a washer 4 is also provided between the nut 5 and the external equipment to increase the friction between the nut 5 and the external equipment, prevent the nut 5 from loosening on its own due to vibration during long-term use, and at the same time, the washer 4 can also disperse the pressure of the nut 5 on the surface of the external equipment, avoid the equipment surface from being indented or damaged due to excessive local force, and further improve the stability of the installation of the female connector 1 and the protection of the equipment. In addition, the washer 4 is made of an elastic material, such as rubber, which will produce a certain elastic deformation when the nut 5 is tightened. This deformation can compensate for the slight unevenness of the mounting surface and ensure that the clamping force between the nut 5 and the retaining ring 3 is evenly distributed, thereby making the fixing of the female connector 1 more secure and reliable.
[0027] Among them, the side of the rubber ring 6 facing the threaded cap 7 is inclined, and the rubber ring 6 expands after being squeezed by the threaded cap 7 and wraps around the threaded cap 7. This inclined design allows the rubber ring 6 to expand outward more smoothly when squeezed by the threaded cap 7. At the same time, the guiding effect of the inclined surface makes the rubber ring 6 fit tightly against the inner wall of the threaded cap 7. As the threaded cap 7 continues to tighten, the expansion of the rubber ring 6 gradually increases, and its outer edge tightly wraps around the outer wall of the threaded cap 7 near the female connector 1, filling the tiny gap between the threaded cap 7 and the female connector 1. This enveloping contact increases the friction between the threaded cap 7 and the female connector 1, helping to resist the tendency of the threaded connection to loosen. At the same time, the elastic restoring force of the rubber ring 6 itself will continue to act on the threaded cap 7, ensuring stable pressure at the thread engagement point, thus significantly enhancing the anti-loosening effect.
[0028] The working principle of this utility model: After the female connector 2 is inserted into the female connector 1, firstly, rotate the threaded cap 7 to move it along the outer wall of the female connector 2 toward the female connector 1. At this time, the thread on the inner wall of the threaded cap 7 gradually engages with the thread groove on the outer wall of the female connector 1. As the threaded cap 7 is continuously tightened, the female connector 2 is stably pulled into the female connector 1 and initially fixed. Meanwhile, as the threaded cap 7 continues to tighten, the expansion of the rubber ring 6 gradually increases, and its outer edge tightly wraps around the outer wall of the threaded cap 7 near the female connector 1, filling the tiny gap between the threaded cap 7 and the female connector 1. Then, insert block 10 is inserted into the gap. At this time, under the action of cap 8 and thread cap 7, the elastic plate 11 is squeezed and deformed, thereby applying a force to push thread cap 7 to move towards female connector 1. This force can effectively counteract the loosening tendency of threaded connection caused by vibration, temperature change and other factors during long-term use, and further enhance the connection tightness between thread cap 7 and female connector 1. At the same time, after the elastic plate 11 is bent, it is inserted into the slot 9, but it does not fit against the bottom inner wall of the slot 9. This not only provides a stable deformation space for the elastic plate 11, but also forms a radial limit on it, so as to prevent the elastic plate 11 from shifting when subjected to force and affecting the anti-loosening effect.
