DETAILED DESCRIPTION
[0029] The following is combined with Figure 2-7 This application is described in further detail.
[0030] The embodiment of the present application discloses a plug-in connector.
[0031] Reference Figure 2 The plug-in connector includes a mounting base 1, three connectors 2 and a fastening assembly 4. A plug-in slot 11 matching the shape of the connector 7 is provided on one side of the mounting base 1, and the three connectors 2 are fixedly connected in the plug-in slot 11.
[0032] Reference Figure 2 and Figure 3 , wherein the fastening assembly 4 includes a mounting plate 41, a fastening rod 42, a torsion spring 43, a slider 44 and a first pull rope 45. The mounting plate 41 is limited in the plug-in slot 11, and three clearance slots 411 are provided on the mounting plate 41 for the three connectors 2 to be movably inserted. The fastening rod 42 is arranged in an "L" shape, one end of the fastening rod 42 is rotatably connected to the mounting plate 41 through a rotating shaft 421, the torsion spring 43 is sleeved on the rotating shaft 421 and one end is fixedly connected to the fastening rod 42, and the other end of the torsion spring 43 is fixedly connected to the mounting plate 41 to drive the fastening rod 42 to rotate and reset. When one end of the connector 7 is plugged into the plug-in slot 11, the torsion spring 43 causes the fastening rod 42 to be clamped to the connector 7.
[0033] A sliding groove 12 is provided on one side of the mounting seat 1 located at the plug-in groove 11, and a slider 44 is slidably connected to the sliding groove 12. A first pull rope 45 is movably arranged in the mounting seat 1, and one end of the first pull rope 45 is fixedly connected to the fastening rod 42, and the other end is fixedly connected to one end of the slider 44. When the slider 44 is slid, the slider 44 drives the first pull rope 45 to move, so that the first pull rope 45 drives the fastening rod 42 to rotate, and the direction of rotation is opposite to the direction in which the fastening rod 42 is driven to rotate by the torsion spring 43.
[0034] Reference Figure 4 and Figure 5In actual application, after one end of the connector 7 is partially inserted into the insertion slot 11 of the mounting seat 1, the slider 44 is slid so that the slider 44 pulls the first pull rope 45 to drive the fastening rod 42 to rotate. At this time, one end of the connector 7 can be completely inserted into the insertion slot 11. Then, the slider 44 is released, and the fastening rod 42 is rotated and reset under the action of the torsion spring 43, so that the fastening rod 42 is clamped on the connector 7 to limit the displacement of the connector 7, further fix the connector 7, and enable the connector 7 to be more stably inserted into the insertion slot 11, thereby reducing the loosening of the connector 7 and improving the stability of the connection between the connector 7 and the connector. It should be noted that when the connector 7 needs to be removed, the slider 44 is slid again, and then the connector 7 is pulled out of the insertion slot 11.
[0035] In some embodiments, a first chamfer 422 is provided on the side of the fastening rod 42 away from the rotation end (i.e., the end away from the rotating shaft 421) and away from the mounting plate 41. When one end of the connecting member 7 is inserted into the plug-in slot 11, the connecting member 7 abuts against the first chamfer 422. Under the guidance of the first chamfer 422, the fastening rod 42 can rotate automatically, and the fastening rod 42 can be clamped on the connecting member 7 without the need for a sliding slider 44, thereby facilitating the installation of the connecting member 7.
[0036] Reference Figure 5 and Figure 6 In some embodiments, the connector further includes a plurality of first springs 5 and a plurality of stopper assemblies 6. The first springs 5 are described as three in number. One end of the three first springs 5 is fixedly connected to the bottom wall of the plug slot 11, and the other end is fixedly connected to the mounting plate 41 to drive the mounting plate 41 away from the bottom wall of the plug slot 11. It should be noted that the three first springs 5 are respectively sleeved on the three connectors 2 to avoid bending and deformation of the first springs 5 as much as possible, so as to increase the service life of the first springs 5.
[0037] In this embodiment, there are three limit assemblies 6, and the three limit assemblies 6 are evenly spaced along the circumference of the plug-in slot 11. Specifically, the limit assemblies 6 include a limit block 61 and a second spring 62. The side wall of the mounting seat 1 located at the plug-in slot 11 is provided with three mounting holes 13. The limit block 61 is slidably connected to the mounting hole 13. One end of the second spring 62 is fixedly connected to the bottom wall of the mounting hole 13, and the other end is fixedly connected to the limit block 61, so as to drive the limit block 61 to extend out of the mounting hole 13, so that the side of the mounting plate 41 away from the first spring 5 abuts against the limit block 61. At this time, the mounting plate 41 is limited under the abutment of the three limit blocks 61, so as to ensure that the fastening rod 42 on the mounting plate 41 can clamp and fix one end of the connector 7. Among them, each limit block 61 compresses each second spring 62, so that each limit block 61 extends into each mounting hole 13, and the mounting plate 41 moves under the drive of the three first springs 5, and the mounting plate 41 is located at the end of the plug-in slot 11 to cover the plug-in slot 11. It can effectively reduce dust from entering the plug-in slot 11 during transportation or when not in use, and try to avoid damage to the connector 2, thereby ensuring the subsequent normal use of the connector.
[0038] Reference Figure 7 In some embodiments, the mounting plate 41 is provided with a rubber baffle 412 at each of the clearance grooves 411. The rubber baffle 412 is made of rubber material, and a "cross"-shaped groove is provided in the rubber baffle 412 for the connector 2 to be movably inserted. When the mounting plate 41 is located at one end of the plug slot 11, each connector 2 is separated from each rubber baffle 412. Since the rubber baffle 412 has a certain elasticity, the groove of the rubber baffle 412 for the connector 2 to be inserted can be reset, so that the rubber baffle 412 can better seal the clearance groove 411, that is, the clearance groove 411 is shielded, further reducing dust from entering the plug slot 11.
[0039] In some embodiments, a penetration portion 21 is provided at one end of the connector 2 away from the bottom wall of the insertion slot 11. The penetration portion 21 is arranged in a cone shape, so that the connector 2 can be more easily penetrated by the rubber baffle 412, thereby facilitating the resetting of the mounting plate 41.
[0040] In some embodiments, an abutment portion 22 is provided at one end of the connector 2 close to the bottom wall of the plug-in slot 11. The abutment portion 22 has a larger diameter, so that the side of the mounting plate 41 close to the first spring 5 abuts against the abutment portion 22, and the mounting plate 41 is prevented from further compressing the first spring 5 for displacement as much as possible. In this way, the mounting plate 41 is limited between the three limit blocks 61 and the three abutment portions 22, completely limiting the displacement of the mounting plate 41, and further ensuring the connection stability between the fastening rod 42 and one end of the connecting member 7.
[0041] Reference Figure 5In some embodiments, a second chamfer 611 is provided on one side of the stopper 61 away from one end of the second spring 62 and away from the bottom wall of the plug-in slot 11. When the connector 7 needs to be plugged in, the mounting plate 41 is pressed so that the mounting plate 41 squeezes the three first springs 5, and then the mounting plate 41 abuts against the second chamfers 611 of the three stopper blocks 61. Under the guidance of the second chamfers 611, the stopper blocks 61 can automatically extend into the mounting holes 13, so that the mounting plate 41 can be limited to the stopper blocks 61, thereby facilitating the use of the connector. In addition, before plugging in the connector 7, the fastening rod 42 on the mounting plate 41 at the end of the plug-in slot 11 can be firstly connected to the connector 7, so that the connector 7 and the mounting plate 41 are installed synchronously, which is also convenient for plugging and installing the connector 7.
[0042] Reference Figure 2 and Figure 5 In some embodiments, the limiting assembly 6 also includes a second pull rope 63, which is movably arranged in the mounting seat 1, and one end of the second pull rope 63 is fixedly connected to one end of the limiting block 61 close to the second spring 62, and the other end is fixedly connected to one end of the slider 44 close to the first pull rope 45. By sliding the slider 44, the slider 44 drives the second pull rope 63 to pull the limiting block 61, so that the limiting block 61 compresses the second spring 62 and extends into the mounting hole 13, so as to release the limiting block 61 from limiting the mounting plate 41, and also facilitate limiting the mounting plate 41 to each limiting block 61.
[0043] Among them, when the mounting plate 41 is limited between the three limit blocks 61 and the three abutment portions 22, the slider 44 is located at the initial position, and the first pull rope 45 is in a relaxed state, and the three second pull ropes 63 are all in a tightened state. By sliding the slider 44, the slider 44 first pulls each limit block 61 through each second pull rope 63, so that each limit block 61 extends into each mounting hole 13, so that the mounting plate 41 passes through each mounting hole 13 under the drive of the three first springs 5. At this time, when the connecting member 7 is pulled out, the mounting plate 41 drives the connecting member 7 to pop out under the action of the three first springs 5. At the same time, before the mounting plate 41 moves to the end of the plug-in slot 11, the first pull rope 45 is in a tightened state, so that the fastening rod 42 can rotate, and the fastening rod 42 can be disengaged from the clamping of the connecting member 7, thereby facilitating the disassembly of the connecting member 7.
[0044] Reference Figure 2 and Figure 6 In some embodiments, the mounting seat 1 is provided with an embedding groove 14 on one side of the plug-in slot 11. The embedding groove 14 is arranged at intervals along the circumference of the plug-in slot 11. The embedding groove 14 is connected to the plug-in slot 11, and the connector 7 is also embedded in the embedding groove 14, so that the connector 7 can be more tightly plugged into the plug-in slot 11, reducing the loosening of the connector 7 and further improving the stability of the connection between the connector 7 and the connector.
[0045] The implementation principle of this embodiment is as follows: in actual application, after one end of the connector 7 is partially inserted into the insertion slot 11 of the mounting seat 1, the slider 44 is slid so that the slider 44 pulls the first pull rope 45 to drive the fastening rod 42 to rotate. At this time, one end of the connector 7 can be completely inserted into the insertion slot 11. Then, the slider 44 is released, and the fastening rod 42 is rotated and reset under the action of the torsion spring 43, so that the fastening rod 42 is clamped on the connector 7 to limit the displacement of the connector 7, further fix the connector 7, and enable the connector 7 to be more stably inserted into the insertion slot 11, thereby reducing the loosening of the connector 7 and improving the stability of the connection between the connector 7 and the connector. It should be noted that when the connector 7 needs to be removed, the slider 44 is slid again, and then the connector 7 is pulled out of the insertion slot 11.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
