[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First embodiment:

[0030] Please refer to the following: Figures 1-2In the first embodiment of the present invention, the display connector includes a male plastic shell 5 and a female inner core 9, which are in a plug-in state during use. A waterproof cover plate 1 is fixedly installed on the male plastic shell 5 by screws. The screws used for connection are common connecting tools on the market and are not shown in the figure. A sealing ring is fixedly installed on the side of the waterproof cover plate 1 away from the male plastic shell 5, so as to play a role in waterproofing and dustproofing. A male plastic shell 4 is wrapped on the male plastic shell 5 to play a role in fixing the wires and waterproofing. A grounding pin 2 and two male female pins 3 are fixedly installed inside the male plastic shell 5. The grounding pin 2 and the male female pins 3 are both gold-plated contacts. Two copper pillars 6 are installed inside the female inner core 9. A first spring 7 is fixedly installed inside the female inner core 9. The copper pillars 6 are used to lock the first spring 7 and fix the lock mentioned below. The function of buckle 12 is as follows: a waterproof rubber ring 8 is fixedly installed on one side of the female connector inner core 9, which also serves as a dustproof and waterproof function. A female connector pin 10 is fixedly installed inside the female connector inner core 9. The female connector pin 10 is inserted into the grounding pin 2, which serves to protect the connector and prevent lightning strikes. Two female connector male pins 11 are fixedly installed inside the female connector inner core 9. The two female connector male pins 11 are respectively inserted into the two male connector female pins 3, so as to transmit current. A locking buckle 12 is rotatably installed on the female connector inner core 9. The locking buckle 12 can cooperate with the male connector plastic shell 5. With the assistance of the copper pillar 6 and the first spring 7, it can firmly insert the female connector inner core 9 into the male connector plastic shell 5, which serves as a limiting function. The female connector inner core 9 is wrapped with a female connector rubber 13. The female connector rubber 13 has the same function as the male connector rubber 4, which can serve to fix the wire and waterproof.

[0031] In this embodiment

[0032] When it is necessary to connect the female connector and the male connector, first align the male pin 11 of the female connector with the female pin 3 of the male connector, and align the female pin 10 of the female connector with the grounding pin 2. Then, insert the inner core 9 of the female connector into the plastic shell 5 of the male connector. After it is in place, rotate the locking buckle 12. At this time, by using the action of the copper post 6 and the first spring 7, as well as the matching relationship between the locking buckle 12 and the plastic shell 5 of the male connector, the locking buckle 12 can be locked on the plastic shell 5 of the male connector, thereby completing the connection between the female connector and the male connector. Under the action of the locking buckle 12, it cannot be easily pulled out.

[0033] When it is necessary to remove the female head, simply rotate the locking buckle 12 in reverse to eliminate the locking effect between it and the male seat plastic shell 5, and then the female head can be removed directly.

[0034] Compared with related technologies, the display connector provided by the present invention has the following advantages:

[0035] 1. The present invention, through the locking effect between the locking buckle 12 and the male plastic shell 5, can limit the connection between the female and male connectors, making them difficult to separate and ensuring normal playback of the display screen.

[0036] Second, the present invention, through the setting of waterproof cover plate 1, sealing ring and waterproof rubber ring 8, can achieve good waterproof and dustproof effect. In addition, the male connector rubber wrap 4 and the female connector rubber wrap 13 can protect and waterproof the wire.

[0037] Second embodiment:

[0038] Based on the display connector provided in the first embodiment of this application, the second embodiment of this application proposes another display connector. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0039] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Please refer to the following: Figures 3-8 The display connector also includes two sheet metal boxes 14, which are fixedly installed on both sides of the male plastic shell 5. Each sheet metal box 14 contains a retaining plate 17. Two retaining ears 15 are fixedly installed on the female rubber cover 13. Positioning levers 16 are fixedly installed on the side of each retaining ear 15 closest to the male plastic shell 5. The ends of the two positioning levers 16 extend into the two sheet metal boxes 14 and are fixedly connected to the corresponding retaining plates 17. Ball-head retaining strips 18 are fixedly installed on the side of each retaining plate 17 away from the positioning levers 16. A U-shaped slide rod 19 is fixedly installed on the top of the male plastic shell 5. A connecting strip 20 is slidably installed on the U-shaped slide rod 19. Two linkage plates 21 are fixedly installed at the bottom of the connecting strip 20. Mounting posts 22 are fixedly installed at the bottom of each linkage plate 21. Right-angled trapezoidal top seats 23 are fixedly installed at the bottom of each mounting post 22. Each of the two ball-head fixing strips 18 is adapted to the right trapezoidal top seat 23. The only hypotenuse of the right trapezoidal top seat 23 can cooperate with the ball-head fixing strip 18. When the right trapezoidal top seat 23 descends, its hypotenuse contacts the ball-head fixing strip 18, thereby pushing against the ball-head fixing strip 18 and pushing the female head out of the male seat. Two retaining rings 24 located above the bracket strip 20 are fixedly sleeved on the U-shaped slide rod 19. Two second springs 25 are sleeved on the U-shaped slide rod 19. The top of the second spring 25 is fixedly connected to the two retaining rings 24 respectively, and the bottom of the two second springs 25 is fixedly connected to the bracket strip 20. In order to ensure that the right-angled trapezoidal top seat 23 can smoothly enter the sheet metal box 14 and form a contact fit with the ball head fixing strip 18, a shuttle opening is provided on the top of the two sheet metal boxes 14. The diameter of the two shuttle openings is larger than the outer dimensions of the two right-angled trapezoidal top seats 23, thereby providing telescopic space for the right-angled trapezoidal top seats 23.

[0041] Please refer to the details. Figure 8In the above-described manner, to further ensure the stability of the connection between the female head and the male seat, a recessed groove 26 is provided on the side of each of the two retaining plates 17 that are far apart from each other. A fixed frame 27 is fixedly installed on the outer wall of each of the two sheet metal boxes 14 that are far apart from each other. A sliding piece 28 is slidably installed in each of the two fixed frames 27. A right-angled trapezoidal linkage block 29 is fixedly installed on the side of each of the two sliding pieces 28 that are close to each other. The side of each of the two right-angled trapezoidal linkage blocks 29 that is close to each other extends into the two recessed grooves 26, and the two right-angled trapezoidal linkage blocks 29 are slidably connected to the two sheet metal boxes 14 respectively. The two right-angled trapezoidal linkage blocks 29 are respectively adapted to the two ball head fixing strips 18. This fitting relationship can be used during the insertion of the retaining plate 17 into the sheet metal box 14. When the retaining plate 17 is inserted into the sheet metal box 14, when the only hypotenuse of the right-angled trapezoidal linkage block 29 contacts the ball head fixing strip 18 on the retaining plate 17, it will abut against the right-angled trapezoidal linkage block 29, thus not hindering the female head from being smoothly inserted into the male socket. Furthermore, in order to simultaneously bring out the two right-angled trapezoidal linkage blocks 29 from their corresponding recesses 26, transverse guide posts 30 are slidably installed on the opposite sides of the two fixed frames 27. The ends of the two transverse guide posts 30 that are close to each other are respectively fixedly connected to the two sliding pieces 28, and the ends of the two transverse guide posts 30 that are far apart are fixedly connected to the opposite sides of the two fixed frames 27. Each end is fixedly equipped with an adapter block 31. A third spring 32 is fitted onto each of the two transverse guide posts 30. The ends of the two third springs 32 that are close to each other are fixedly connected to the two fixed frames 27, while the ends that are far apart are fixedly connected to the two adapter blocks 31. Each adapter block 31 has a recessed triangular groove 33, which is a right-angled triangle, having a unique hypotenuse, similar to the right-angled trapezoidal top seat 23 and the right-angled trapezoidal linkage block 29. Vertical guide posts 34 are slidably mounted on each of the two linkage plates 21. Positioning plates 35 are fixedly mounted at the bottom of each of the two vertical guide posts 34. Abutment plates are fixedly mounted on the far sides of each of the two positioning plates 35. The sliding pieces 36 have two abutting sliding pieces with their bottoms set at an angle. The angled bottom edges of the abutting sliding pieces 36 are adapted to the recessed triangular grooves 33. Each of the two vertical guide posts 34 is fitted with a fourth spring 37. The top ends of the two fourth springs 37 are fixedly connected to the two linkage plates 21 respectively, and the bottom ends of the two fourth springs 37 are fixedly connected to the two positioning plates 35 respectively. The bottom of the abutting sliding piece 36 is lower than the bottom of the right-angled trapezoidal top seat 23. Furthermore, the elastic coefficient of the fourth spring 37 is greater than the elastic coefficient of the third spring 32. Therefore, when the abutting sliding piece 36 contacts the inner wall of the recessed triangular groove 33, the abutting sliding piece 36 can continue to descend without being affected by the third spring 32.

[0042] Please refer to the details. Figure 4In this method, in order to ensure that the right-angled trapezoidal linkage block 29 can slide on the sheet metal box 14, a sliding interface is provided on the side of the two sheet metal boxes 14 that are far apart from each other, and the two right-angled trapezoidal linkage blocks 29 pass through the two sliding interfaces respectively.

[0043] Please refer to the details. Figure 8 In this method, in order to provide maximum movement restriction for the sliding piece 28, limit sliding openings are provided on both sides of the two fixed frames 27, and the two sliding pieces 28 pass through the corresponding limit sliding openings and contact the inner wall of the corresponding limit sliding openings.

[0044] In this embodiment

[0045] Because the connection between the female connector and the male connector is usually quite tight and has a certain degree of damping, during the removal process, on the one hand, in situations where space is limited, it is important to prevent the arm from colliding with external objects due to inertia and causing bruises or other injuries to the arm or back of the hand when the female connector is pulled out quickly. On the other hand, some people will swing the female connector up and down or left and right back and forth to gradually pull it out of the male connector. Over time, this swinging method will cause the diameter of the male connector to gradually increase, which will lead to a loose connection between the female connector and the male connector during later use, and may easily cause poor contact.

[0046] To avoid the aforementioned problems, when it is necessary to remove the inner core 9 of the female connector, first rotate the locking buckle 12 to release its locking effect with the plastic shell 5 of the male connector. Then press down the bracket connecting strip 20 to lower the two linkage plates 21. At this time, the second spring 25 gradually stretches, thereby driving the right-angled trapezoidal top seat 23 and the contact slide 36 to descend. During the descent, since the bottom of the contact slide 36 is lower than the bottom of the right-angled trapezoidal top seat 23, the two contact slides 36 will first enter the corresponding recessed triangular groove 33. At the same time, the corresponding contact slide 36 will engage with the corresponding recessed triangular groove 33, causing the two adapter blocks 31 to move away from each other. At this time, since the elastic coefficient of the fourth spring 37 is greater than that of the third spring 32, the two third springs 32 will stretch, while the contact slides 36 continue to descend. At this time, under the action of the two transverse guide posts 30, the two right-angled trapezoidal linkage blocks 29 Gradually, the sliding piece 28 moves out of the corresponding recess 26 until it touches the inner wall of the limiting slide. Then, the right-angled trapezoidal linkage block 29 completely moves out of the recess 26. Simultaneously, limited by the limiting slide, the adapter block 31 stops moving laterally. At this point, the frame connecting strip 20 is continuously pressed, and the two fourth springs 37 are compressed under greater pressure. Immediately afterwards, the two right-angled trapezoidal top seats 23 enter the corresponding sheet metal box 1 through the corresponding shuttle opening. Inside 4, it simultaneously engages with the corresponding ball head fixing strip 18. Under the action of the inclined side of the right-angled trapezoidal top seat 23, the two retaining plates 17 are gradually pushed out. At this time, the inner core 9 of the female head gradually exits from the plastic shell 5 of the male seat. After the inner core 9 of the female head is completely exited, the bracket strip 20 can be released. The stretched second spring 25, the stretched third spring 32, and the compressed fourth spring 37 all release their elasticity, allowing each component to return to its original position, thereby completing the removal of the female head.

[0047] Similarly, when the female core 9 needs to be inserted, before it is inserted into the male plastic shell 5, the two retaining plates 17 first enter the corresponding sheet metal box 14. When the ball head fixing strip 18 on it contacts the right-angle trapezoidal linkage block 29, the two engage with each other, causing the two right-angle trapezoidal linkage blocks 29 to move away from each other. At this time, the third spring 32 will be in a stretched state. When the right-angle trapezoidal linkage block 29 is horizontally aligned with the insertion groove 26, the stretched third spring 32 releases its elasticity, instantly bringing the right-angle trapezoidal linkage block 29 into the insertion groove 26. At this time, the female core 9 has been inserted.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
