Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable plug-in head, in particular to a loosening-preventing cable plug-in head based on emergency power supply. BACKGROUND

[0002] The cable plug-in head is a key component for connecting or disconnecting cables and electrical equipment, which realizes quick and safe electrical connection and separation through the plug-in design, and is widely used in power transmission, industrial control, communication equipment, new energy vehicles and other fields.

[0003] In the actual application of the emergency power supply system, the traditional cable plug-in head lacks effective support and fixing mechanism after the front and rear plugs are inserted into each other, and the rear plug is easily affected by its own gravity, cable pulling force and external vibration, etc. During the connection with the front plug, the connection is offset, which not only causes the signal transmission line to be unable to be accurately connected, and further causes signal interference, attenuation or loss. For example, in the emergency power supply system of the communication base station, if the cable plug-in head is connected and offset, the communication signal between the base station and the monitoring center will be deviated, affecting the real-time monitoring and remote control of the operation state of the base station, and even in an emergency, effective measures cannot be taken in time. Moreover, the traditional cable plug-in head cannot maintain the vertical and parallel connection state between the front and rear plugs, so that the contactors cannot be tightly attached, and in the long-term use process, the contact surface will be oxidized and worn due to factors such as oxidation and wear, which will gradually increase the contact resistance. The weight of the rear plug and the pulling force of the cable are mainly concentrated on the connection, and there is a lack of effective dispersion mechanism. The concentration of mechanical stress will cause the connection to bear excessive pressure, accelerating the fatigue and wear of the connector material.

[0004] Therefore, the present application provides a loosening-preventing cable plug-in head based on emergency power supply to solve the above problems. SUMMARY

[0039] The technical solutions of the application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the application.

[0040] The anti-loose cable plug of the embodiment based on the emergency power supply, as shown in Figure 1 - Figure 9As shown, it includes a front plug body 1 and a rear plug body 2, which are clamped together, and also include a vertical limiting mechanism and a connection port sealing mechanism. The vertical limiting mechanism includes a fixing plate 301 and a fixing ring 302. The fixing plate 301 is fixedly connected to the front plug body 1, and the fixing ring 302 is fixedly connected to the rear plug body 2.

A support block 313 is fixedly connected at the center of the side of the fixing plate 301 close to the fixing ring 302, and a connecting shaft 309 is rotatably connected to the support block 313. The vertical limiting mechanism is used to maintain the vertical and parallel connection between the front plug body 1 and the rear plug body 2.

[0041] In this embodiment, Figure 3 As shown, vertical grooves 312 are symmetrically provided on the outer surface of the connecting shaft 309, and sliding columns 319 are slidably connected in the vertical grooves 312.

Under the influence of the gravity of the counterweight block 308 itself, the lifting plate 307 will be pushed to automatically descend, pushing the lifting plate 307 to drive the linkage plates 311 rotatably connected on both sides to move, so that the linkage plate 311 pushes the support plate 304 to move horizontally synchronously.

[0042] In this embodiment, Figure 7 As shown, spiral grooves 320 are symmetrically provided on the outer surface of the connecting shaft 309, and the lower ends of the spiral grooves 320 are connected to the upper ends of the vertical grooves 312.

The outer surface of the connecting shaft 309 is symmetrically provided with limiting grooves 321, and one end of the limiting grooves 321 is connected to the upper ends of the spiral grooves 320. The limiting grooves 321 are used to limit the position of the sliding posts 319. When the sliding posts 319 slide along the spiral grooves 320, the connecting shaft 309 will be rotated. When the sliding posts 319 slide into the limiting grooves 321, the height of the sliding posts 319 will be limited.

[0043] In this embodiment, Figure 1 As shown, the lower end surface of the lifting plate 307 is symmetrically fixedly connected with the clamping column 306, and the outer surface of the fixing ring 302 is symmetrically fixedly connected with the connecting plate 305. The connecting plates 305 are all located directly below the clamping column 306, and the clamping column 306 is clamped with the connecting plate 305. During the descending process of the lifting plate 307, the clamping column 306 will be driven to descend synchronously and be clamped on the connecting plate 305.

[0044] In this embodiment, Figure 6As shown, the lower end of the connecting shaft 309 is fixedly connected with a disc 317, the outer surface of the disc 317 is fixedly connected with a convex plate 316, the convex plate 316 is provided with a fixed column 315 close to one side of the fixed ring 302, the fixed column 315 is fixedly connected to the outer surface of the fixed ring 302, the fixed column 315 is used to push the convex plate 316 to move, when the fixed ring 302 drives the fixed column 315 to approach the disc 317, the fixed column 315 will push the convex plate 316 to drive the disc 317 to rotate, so that the connecting shaft 309 connected to the upper end surface of the disc 317 rotates.

[0045] In the embodiment, as shown in Figure 6 The upper end surface of the disc 317 is fixedly connected with a torsion spring 318, one end of the torsion spring 318 away from the disc 317 is fixedly connected to the lower end surface of the support block 313, the torsion spring 318 is sleeved on the outer surface of the connecting shaft 309, when the disc 317 is forced to rotate to drive the connecting shaft 309 to rotate, the torsion spring 318 will be synchronously extruded, when the force disappears, the disc 317 can be pushed to drive the connecting shaft 309 to rotate in the opposite direction by the rebound force of the torsion spring 318.

[0046] In the embodiment, as shown in Figure 4 The upper end surface of the support plate 304 is fixedly connected with a pressure sensor 314, the upper end surface of the fixed plate 301 is fixedly connected with an alarm lamp 310, the pressure sensor 314 and the alarm lamp 310 are electrically connected, when the pressure received by the pressure sensor 314 is abnormal, the alarm lamp 310 can be synchronously turned on to work.

[0047] In the prior art, the traditional cable plug is lack of effective support and fixing mechanism after the front and rear plugs are inserted into each other. The rear plug is easily affected by its own gravity, cable pulling force and external vibration, etc. and deviates during the connection with the front plug. The deviation of connection not only causes the signal transmission line to be unable to be accurately connected, thereby causing signal interference, attenuation or loss, but also causes the contact pieces to be unable to be tightly attached due to the inability of the traditional cable plug to maintain the vertical and parallel connection state between the front and rear plugs. In the long-term use process, the contact resistance gradually increases due to oxidation and wear, etc. The weight of the rear plug and the pulling force of the cable are mainly concentrated at the connection, and there is lack of effective dispersion mechanism. The concentration of mechanical stress causes the connection to bear excessive pressure, accelerates the fatigue and wear of the connector material. Compared with the prior art, the support plate 304 is driven to slide out from the inside of the fixed plate 301 after the front plug body 1 and the rear plug body 2 are inserted into each other, so that the support plate 304 supports the side plate 303, maintains the vertical and parallel state between the front plug body 1 and the rear plug body 2, and avoids the rear plug body 2 from deviating during the connection with the front plug body 1 due to its own gravity or pulling. Not only can the accurate connection of the signal transmission line be ensured, the signal interference, attenuation or loss caused by the deviation of connection can be reduced, and the deviation of data transmitted through the interface due to the deviation of the rear plug body 2 can be prevented, thereby affecting the normal operation of the entire system. Moreover, the vertical and parallel connection state can ensure that the contact pieces of the front plug body 1 and the rear plug body 2 are tightly attached, reduce the contact resistance, improve the stability of electrical connection, and the support of the support plate 304 can effectively disperse the weight of the rear plug body 2, reduce the mechanical stress of the connection between the front plug body 1 and the rear plug body 2, and prolong the service life of the connector.

[0048] The pressure sensor 314 and the alarm lamp 310 are arranged, so that when the front plug body 1 and the rear plug body 2 are connected and the rear plug body 2 is affected by the pulling factor, the pressure of the fixed ring 302 and the side plate 303 on the pressure sensor 314 suddenly increases, and the alarm lamp 310 is automatically turned on to work. Not only can the pressure change of the rear plug body 2 during the connection process be monitored in real time to ensure the stability of the connection process and avoid connection problems caused by excessive pressure, but also the pressure sensor 314 can detect abnormal pressure between the rear plug body 2 and the front plug body 1 to find the connection looseness in time and avoid electrical faults caused by poor contact.

[0049] In other aspects, the embodiment also provides a connection port sealing mechanism for protecting the connection between the front plug body 1 and the rear plug body 2, as shown in Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, the connection port sealing mechanism includes a movable protective shell 401 and a fixed protective shell 402. The inner wall of the movable protective shell 401 is symmetrically fixedly connected with a slider, and the outer surface of the front plug body 1 is symmetrically provided with a slide groove. The movable protective shell 401 is slidably connected to the outer surface of the front plug body 1 through the provided slider and slide groove, and the fixed protective shell 402 is fixedly connected to the outer surface of the rear plug body 2.

[0050] In this embodiment, Figure 8 As shown, a sealing ring 406 is fixedly connected to the side of the mobile protective shell 401 close to the fixed protective shell 402, and an annular sealing groove 407 is opened on the side of the fixed protective shell 402 close to the sealing ring 406. The sealing ring 406 and the annular sealing groove 407 are engaged with each other. When the mobile protective shell 401 moves close to the fixed protective shell 402, the sealing ring 406 can be driven to be engaged in the annular sealing groove 407, thereby improving the sealing between the mobile protective shell 401 and the fixed protective shell 402.

[0051] In this embodiment, Figure 9 As shown, a connecting frame 403 is fixedly connected to the lower surface of the mobile protective shell 401, and a groove 408 is provided on the lower end surface of the connecting frame 403. A toggle rod 404 is slidably connected in the groove 408. A toggle plate 405 is fixedly connected to the lower end surface of the toggle rod 404. The toggle plate 405 is fixedly connected to the upper end of the connecting shaft 309. When the connecting shaft 309 rotates, the toggle plate 405 can drive the toggle rod 404 to slide in the groove 408 provided on the lower end surface of the connecting frame 403, and the toggle rod 404 drives the connecting frame 403 through the groove 408 to drive the mobile protective shell 401 to move horizontally.

[0052] Compared with the existing technology, the movable protective shell 401 can be driven to slide on the front plug body 1 close to the fixed protective shell 402, and the sealing ring 406 can be clamped into the annular sealing groove 407 to seal and protect the connection between the front plug body 1 and the rear plug body 2. This can not only effectively prevent dust, moisture and other pollutants from entering the connection, extend the service life of the front plug body 1 and the rear plug body 2, and significantly improve the protection level after the plug is connected, but also the sealing protection can prevent poor contact due to external environmental factors (such as humidity and dust), thereby ensuring the stability and reliability of the electrical connection.

[0053] The working process and principles involved in the overall content of the above embodiment are as follows:

[0054] When the staff inserts the rear plug body 2 into the front plug body 1, the fixed ring 302 connected to the outer surface of the rear plug body 2 will approach the fixed plate 301 connected to the outer surface of the front plug body 1 at the same time. Since the outer surface of the fixed ring 302 is fixedly connected with the fixed column 315, and the fixed column 315 and the convex plate 316 are on the same horizontal line, as the fixed ring 302 approaches the fixed plate 301, the fixed ring 302 will drive the fixed column 315 and the convex plate 316 to approach each other, and push the convex plate 316 to move, and the convex plate 316 will push the connected disc 317, drive the connecting shaft 309 to rotate on the support block 313. In the rotating process of the connecting shaft 309, the positions of the limiting grooves 321, the spiral grooves 320 and the vertical grooves 312 symmetrically opened on the outer surface of the connecting shaft 309 will change at the same time. At this time, the slide column 319 located in the limiting groove 321 will first slide out of the limiting groove 321, slide along the spiral groove 320 and finally slide into the vertical groove 312. Since the slide column 319 is connected with the lifting plate 307, and the lifting plate 307 is fixedly connected with the counterweight 308 at the upper end, therefore, when the slide column 319 slides into the vertical groove 312, the lifting plate 307 will automatically descend in the vertical groove 312 under the influence of the gravity of the counterweight 308, which drives the slide column 319. At this time, the lifting plate 307 will push the upper end of the linkage plate 311 to move downward at the same time, so that the linkage plate 311 moves from an inclined state to a horizontal state. With the change of the state of the linkage plate 311, the linkage plate 311 will push the support plate 304 rotatably connected to the end away from the lifting plate 307 to slide out of the fixed plate 301 and extend to the lower end surface of the side plate 303 connected to the outer surface of the fixed plate 301, and abut to the lower end surface of the side plate 303. Through the support of the side plate 303 and the fixed ring 302 to the rear plug body 2, the vertical parallelism between the front plug body 1 and the rear plug body 2 is maintained, so that the rear plug body 2 is prevented from deviating due to its own gravity or pulling during connection with the front plug body 1. Not only can the precise butt joint of the signal transmission line be ensured, the signal interference, attenuation or loss caused by connection deviation can be reduced, the deviation of data transmitted through the interface caused by the deviation of the rear plug body 2 can be prevented, and the normal operation of the whole system can be affected. Moreover, the vertical parallel connection state can ensure that the contact pieces of the front plug body 1 and the rear plug body 2 are tightly abutted, reduce the contact resistance, improve the stability of electrical connection, and effectively disperse the weight of the rear plug body 2 through the support of the support plate 304, reduce the mechanical stress at the connection between the front plug body 1 and the rear plug body 2, and prolong the service life of the connector.

[0055] When the lifting plate 307 is lowered to push the support plate 304 to move to the lower end surface of the side plate 303 through the linkage plate 311, the symmetrically connected clamping column 306 at the lower end of the lifting plate 307 will also be lowered and clamped into the connecting plate 305 connected to the outer surface of the fixed ring 302, so that the front plug body 1 and the rear plug body 2 are re-clamped through the fixed plate 301, the support block 313, the connecting shaft 309, the lifting plate 307, the clamping column 306, the connecting plate 305 and the fixed ring 302, further improving the stability of the front plug body 1 and the rear plug body 2 after plugging;

[0056] Wherein, by setting the fixed column 315, the convex plate 316, the disc 317, the torsional spring 318 and the counterweight 308, the connecting shaft 309 can be automatically rotated during the process of plugging the rear plug body 2 into the front plug body 1, so that the lifting plate 307 drives the sliding column 319 to slide along the path of the limiting groove 321, the spiral groove 320 and the vertical groove 312, and the support plate 304 is automatically pushed to slide to the lower end surface of the side plate 303. Not only can it simplify the operation steps, reduce the time and effort of manual adjustment, and improve the operation efficiency, but also through the automatic support of the mechanical structure, it can avoid the plugging deviation or connection failure caused by improper human operation;

[0057] After the support plate 304 is attached to the lower end surface of the side plate 303, the pressure sensor 314 connected to the upper end surface of the support plate 304 will be located between the support plate 304 and the side plate 303, so that when the rear plug body 2 is connected to the front plug body 1 and the rear plug body 2 is affected by the pulling factor and the pressure on the pressure sensor 314 through the fixed ring 302 and the side plate 303 suddenly increases, the alarm lamp 310 is automatically turned on and works. Not only can it monitor the pressure change of the rear plug body 2 during connection in real time, ensure the stability of the connection process, and avoid connection problems caused by excessive pressure, but also the pressure sensor 314 can detect abnormal pressure between the rear plug body 2 and the front plug body 1, find out the connection problem or looseness in time, and avoid electrical failure caused by poor contact;

[0058] In the process of connecting shaft 309 rotating through slide post 319, lifting plate 307 and linkage plate 311 to push support plate 304 to move to the lower end surface of side plate 303, connecting shaft 309 will drive the connected toggle plate 405 on the upper end surface to rotate synchronously, at this time the toggle plate 405 will toggle the toggle rod 404 connected to the upper end surface to rotate synchronously with the connecting shaft 309 as the center, and drive the toggle rod 404 to slide in the groove 408 opened in the lower end surface of the connecting frame 403. In the process of sliding in the groove 408, the toggle rod 404 will synchronously toggle the connecting frame 403 to move through the groove 408, driving the moving protective shell 401 connected to the upper end surface of the connecting frame 403 to slide horizontally on the outer surface of the front plug body 1 close to the fixed protective shell 402.
