[0022] Please refer to Figure 1 and Figure 2 As shown, this utility model embodiment provides a connector plug, including a connector body 100, a first sealing member 200, a fastening cap 300, and a pin assembly 400; the first end of the connector body 100 is adapted to be inserted into a connector socket, and the second end of the connector body 100 is recessed to form a first placement groove 110, the bottom of the first placement groove 110 is provided with a plurality of first through holes 120; the first sealing member 200 is placed in the first placement groove 110, and the first sealing member 200 is provided with a number and position of the first through holes 120. A matching second through hole 210 is provided; a fastening cover 300 is detachably connected to the second end of the connector body 100, and the fastening cover 300 is adapted to press against the first seal 200 to make a sealed connection between the first seal 200, the fastening cover 300 and the connector body 100. The fastening cover 300 is provided with a third through hole 310 that matches the number and position of the first through hole 120; the pin assembly 400 passes through the third through hole 310, the second through hole 210 and the first through hole 120 in sequence to abut against the contacts in the connector socket.
[0023] According to the connector plug of this utility model embodiment, the pin assembly 400 passes sequentially through the third through hole 310 of the fastening cover 300, the second through hole 210 of the first sealing member 200, and the first through hole 120 of the connector body 100. The fastening cover 300 moves toward the connector body 100 and gradually presses against the first sealing member 200. At the same time, the first sealing member 200 deforms and fits against the groove wall of the first placement groove 110, while the second through hole 210 tightly fits against the pin assembly 400, thereby achieving a seal between the fastening cover 300, the pin assembly 400, and the connector body 100. Disassembly can be performed by reversing the above steps.
[0024] According to the connector plug of this utility model embodiment, by providing a detachable fastening cover 300 and gradually pressing the first sealing member 200 during the process of installing the fastening cover 300 to the connector body 100, the sealing and waterproof effect of the connector plug of the connector body 150 is guaranteed; and, compared with the traditional glue sealing method, the fastening cover 300 of this application is easier to disassemble, which is beneficial to the maintenance of the connector plug and the recycling or replacement of internal components.
[0025] In some embodiments, combined with Figure 1 and Figure 2 As shown, the first end of the connector body 100 is recessed to form a second placement groove 130, and the bottom part of the second placement groove 130 protrudes to form a connector head 140. The connector head 140 is provided with a first through hole 120. The connector plug also includes a second sealing member 500. The second sealing member 500 is annular and sleeved on the connector head 140. There is an installation gap between the second sealing member 500 and the groove wall of the second placement groove 130. The installation gap is suitable for the connector socket to be inserted.
[0026] In this embodiment, the connector socket is inserted into the installation gap, and a seal is formed between the inner wall of the connector socket, the second seal 500 and the outer wall of the connector head 140 to isolate the pin assembly 400 in the first through hole 120 of the connector head 140 from the external environment, preventing moisture from affecting the contact connection between the pin assembly 400 and the connector socket.
[0027] In this embodiment, the contact area between the connector socket and the second seal 500 is increased by setting the installation gap. When the annular second seal 500 is pressed, its outer ring expands outward and fits tightly against the connector socket, while its inner ring contracts inward and fits tightly against the connector head 140, thereby improving the overall sealing effect.
[0028] In some embodiments, combined with Figure 2As shown, the connector body 100 also includes a connector body 150, which covers the connector head 140 and is detachably connected to the connector head 140 and presses against the second seal 500. The connector body 150 is provided with a fourth through hole 151 that matches the number and position of the first through hole 120.
[0029] In this embodiment, the second sealing element 500 is first fitted onto the connector 140, and then the connector body 150 is placed over the connector 140. During the connection of the connector body 150 to the connector 140, the second sealing element 500 is gradually pressed against it, causing the second sealing element 500 to be compressed axially while its outer ring surface expands outward and its inner ring surface contracts inward. After installation, the pin assembly 400 in the first through hole 120 abuts against the contact point of the connector socket through the fourth through hole 151. The pre-compression of the second sealing element 500 by the connector body 150 improves the sealing effect of the second sealing element 500 when the connector plug and connector socket are inserted.
[0030] In some embodiments, combined with Figure 2 As shown, the second sealing member 500 includes a first sealing part 510 and a second sealing part 520 arranged in a stepped manner with progressively increasing cross-sectional areas. The first sealing part 510 is adapted to abut against the connector 150, and the second sealing part 520 is adapted to abut against the bottom of the second placement groove 130.
[0031] In this embodiment, the first sealing part 510, which has a smaller cross-sectional area, is more prone to deformation, making the surface where the connector 150 is connected to the first sealing part 510 fit more closely, thereby improving the sealing effect between the second sealing member 500 and the connector 150.
[0032] In some embodiments, combined with Figure 2 As shown, the outer surface of the second sealing part 520 is provided with several annular grooves, which surround the connector 140.
[0033] In this embodiment, the annular groove makes the outer surface of the second sealing part 520 easier to deform and fit the connector socket, and the space of the annular groove can hold a certain amount of water vapor to improve the sealing effect of the second sealing member 500.
[0034] In some embodiments, combined with Figure 2 As shown, the connector 140 is provided with a plurality of first hooks 141 and a plurality of first slots 142, and every two first hooks 141 form a group symmetrical about the center of the connector 140, and every two first slots 142 form a group symmetrical about the center of the connector 140. The first hooks 141 and the first slots 142 are arranged sequentially around the center of the connector. The connector body 150 is provided with a second slot 152 that mates with the first hooks 141, and a second hook 153 that mates with the first slots 142.
[0035] In this embodiment, by symmetrically distributing the first hook 141 and the first slot 142 on the connector 140, and providing corresponding second hooks 153 and second slots 152 on the connector 150, the guiding fault tolerance during docking is significantly improved, and the risk of misalignment is reduced; the overall stability and mechanical strength of the connection are enhanced, and stress concentration is avoided; bidirectional (X and Z directions) balanced force is achieved, extending the service life of the connector 150 and the connector 140; at the same time, the docking operation process is simplified, and the assembly efficiency and user experience are improved.
[0036] In this embodiment, the connector 140 is provided with two first hooks 141 and two first slots 142. Of course, the specific number can be adjusted according to design requirements. For example, when a hexagonal connector 140 is provided, three first hooks 141 and three first slots 142 can be provided.
[0037] In other embodiments, the detachable connection between the connector 140 and the connector 150 can also be magnetic, threaded, screwed, etc.
[0038] In some embodiments, combined with Figure 1 and Figure 2 As shown, the connector 140 is provided with a claw arm assembly, which is located on the side of the first through hole 120 opposite to the opening of the first seal 200. The number of claw arms is adapted to the first through hole 120. The claw arm assembly includes multiple claw arms 143 centrally symmetrically arranged on both sides of the axis of the first through hole 120. The multiple claw arms 143 can open under the push of the pin assembly 400. The pin assembly 400 includes a pin part 410 and a wire 420. The wire 420 is connected to one end of the pin part 410. The pin part 410 is provided with a snap-fit groove 411, which is adapted to snap-fit with the claw arm 143.
[0039] In this embodiment, during installation, the pin assembly 400 passes sequentially through the third through hole 310, the second through hole 210, and the first through hole 120. After exiting the first through hole 120, it continues to move and push against the claw arm 143, causing the claw arm 143 to open until it aligns with the engagement groove 411 of the pin portion 410. The claw arm 143 then springs back and engages with the engagement groove 411 for a limited stop. The claw arm 143 prevents the pin portion 410 from dislodging from the connector plug when the wire 420 of the pin assembly 400 is pulled, thus improving operational stability.
[0040] In this embodiment, each first through hole 120 is provided with two claw arms 143. Of course, the number of claw arms 143 can also be adjusted according to design requirements, such as one or three.
[0041] In some embodiments, combined with Figure 1 and Figure 2As shown, the outer wall of the connector body 100 is provided with a third hook 161 and a limiting ring 162. The first end of the third hook 161 is connected to the outer wall of the connector body 100, and the free end of the third hook 161 can swing relative to the connector body 100 to cooperate with the connector socket. The two ends of the limiting ring 162 are connected to the outer wall of the connector body 100, and the limiting ring 162 spans across the outside of the third hook 161 to limit the swing angle of the third hook 161.
[0042] In this embodiment, the third hook 161 swings away from the connector body 100 under the push of the connector socket until the connector socket moves to the assembly position. The third hook 161 rebounds to fix the connector body 100 and the connector socket relative to each other. During disassembly, the operator can manually swing the third hook 161 to separate the connector body 100 from the connector socket. During swinging, the limiting ring 162 limits the maximum swing angle of the third hook 161 to prevent the third hook 161 from breaking.
[0043] In other embodiments, the detachable connection between the connector body 100 and the connector socket can also be magnetic, threaded, screwed, etc.
[0044] In some embodiments, combined with Figure 1 As shown, the outer wall of the fastening cover 300 is connected to a fourth hook 320, and the free end of the fourth hook 320 can swing relative to the fastening cover 300; a portion of the wall of the first placement groove 110 is recessed in a direction away from the center of the first placement groove 110 to form a fourth groove (not shown in the figure), and the fourth groove is engaged with the fourth hook 320.
[0045] In this embodiment, the fourth hook 320 and the fourth slot, which are built into the first placement slot 110 in the installation state, can effectively prevent accidental contact with the fourth hook 320 and avoid the fastening cover 300 and the connector body 100 from separating after installation.
[0046] In this embodiment, the fastening cover 300 is provided with a clearance groove corresponding to the fourth hook 320 along the insertion direction of the first placement groove 110. When the fourth hook 320 and the fourth groove are connected, the operator can insert a rod-shaped component into the clearance groove and press against the fourth hook 320 to separate the fourth hook 320 from the fourth groove.
[0047] In other embodiments, the detachable connection between the fastening cover 300 and the connector body 100 can also be magnetic, threaded, screwed, etc.
[0048] On the other hand, this utility model embodiment also provides a rail transit station platform screen door, including the connector plug as described above.
[0049] In this embodiment, the connector plug with good waterproof performance is suitable for the humid environment where the rail transit platform screen doors are located, ensuring the operational stability of the rail transit platform screen doors.
