[0033] Example 1

[0034] Combination Figures 1 to 7 As shown, the modular cable plug 1 of the present invention is schematically displayed, including a housing 10 having a head end 11 and a tail end 12, and the housing 10 also having an internal space capable of accommodating other components.

[0035] like Figure 1 The first end 11 of the housing 10 has a connection hole 111 that communicates with the internal space of the housing 10. The housing 10 has a circuit board 20. The circuit board 20 has a pin 30 that passes through the connection hole 111. The pin 30 can be plugged into the display module 60 to transmit control signals and / or electrical energy.

[0036] like Figure 2 and Figure 3 The tail end 12 of the housing 10 has a mounting port 121, which exposes the circuit board 20 to the outside. Installation and maintenance personnel can solder the circuit board 20 to the pins 30, or process the circuit board 20 for specific signal transmission requirements, eliminating the need for additional, expensive custom-made aviation connectors. After processing the circuit board 20, a sealant (not shown) is poured into the mounting port 121 to contact the circuit board 20. The sealant contacts both the circuit board 20 and the inner wall of the housing 10, preventing moisture from entering the housing 10 and improving the connector's waterproof performance.

[0037] Specifically, such as Figure 3The module cable plug 1 of this utility model also includes a transmission cable 40. The end of the transmission cable 40 is provided with a first terminal 41. One end of the transmission cable 40 with the first terminal 41 passes through the mounting port 121. The circuit board 20 is provided with a second terminal 22, which is connected to the first terminal 41. The transmission cable 40 can connect to an external display control box. The first terminal 41 and the second terminal 22 can use existing universal connectors, reducing material costs. Sealant is applied to the end of the transmission cable 40 to prevent moisture from entering the housing 10. In high-reliability applications, the circuit board 20 can first be installed inside the housing 10, and the pins 30 and the circuit board 20 can be soldered. The first terminal 41 of the transmission cable 40 is then inserted into the second terminal 22 of the circuit board 20. Finally, sealant is poured into the mounting port 121 to fill the space between the circuit board 20 and the mounting port 121, completing the waterproof encapsulation of the plug. Then, the head end 11 of the housing 10 is connected to the display module 60, and the pins 30 are connected to the slot 61 on the display module 60. In addition, the housing 10 is made of existing plastic material, which is cheaper than metal aviation connectors and can avoid the corrosion of metal materials when soaked in water, thus increasing service life while reducing costs.

[0038] The tail end 12 of the housing 10 is provided with a mounting component 122. The mounting component 122 has a mounting groove 1221 that extends through the interior of the housing 10. The end of the transmission cable 40 is embedded in the mounting groove 1221. A pressure plate 50 is detachably connected to the mounting groove 1221. The pressure plate 50 presses the end of the transmission cable 40 against the mounting groove 1221. The pressure plate 50 and the mounting groove 1221 can fix the transmission cable 40 to the tail end 12 of the housing 10. The pressure plate 50 and the mounting groove 1221 are fastened together by multiple screws, which can prevent the end of the transmission cable 40 from swinging relative to the housing 10, thus preventing damage to the sealant and failure of waterproofing. The mounting component 122 is provided with several first fixing holes 1222. The first fixing holes 1222 are located on the outside of the mounting groove 1221. The first fixing holes 1222 can be connected to the display module 60 by existing screws or bolts, improving the tightness of the connection between the display module 60 and the housing 10.

[0039] Furthermore, in combination Figure 5 and Figure 6As shown, the circuit board 20 has a front side 20a and a back side 20b. The front side 20a of the circuit board 20 faces the connection hole 111. Some or all of the pins 30 are located on the front side 20a of the circuit board 20, and the second terminal 22 is located on the back side 20b of the circuit board 20. This structure can improve the utilization of the internal space of the housing 10 and provide enough space for sealant potting, thereby improving the waterproof performance of the plug. The circuit board 20 has a through hole 21 that penetrates both the front side 20a and the back side 20b. One end of the pin 30 passes through the through hole 21 and is soldered to the circuit board 20. The other end of the pin 30 passes through the connection hole 111 and is used to connect to the slot 61 of the display module 60.

[0040] To improve assembly efficiency, such as Figure 3 The housing 10 has several positioning posts 13 inside, and the circuit board 20 has several positioning holes 23. When there are multiple positioning holes 23, they are located at the edge of the circuit board 20. The number of positioning posts 13 and positioning holes 23 is the same, and each positioning post 13 corresponds to one positioning hole 23. The positioning posts 13 can slide through the positioning holes 23. The arrangement of positioning posts 13 and positioning holes 23 can realize the rapid positioning between the circuit board 20 and the housing 10. After the circuit board 20 is placed in the housing 10, the circuit board 20 can be processed. During the processing, the positioning posts 13 and positioning holes 23 can also prevent the circuit board 20 from shifting relative to the housing 10, so as to prevent the circuit board 20 from shaking during processing and affecting the processing quality.

[0041] Combination Figure 1 and Figure 6 As shown, the first end 11 of the housing 10 is provided with a sealing groove 112 surrounding the connecting hole 111. A sealing ring 113 is provided in the sealing groove 112. The sealing ring 113 has an O-shaped cross-section. When the first end 11 of the housing 10 is connected to the display module 60, the sealing ring 113 is deformed by the compression of the sealing groove 112 and the display module 60. The sealing ring 113 can prevent moisture from entering the connection between the pin 30 and the slot 61 from the gap between the first end 11 of the housing 10 and the display module 60. In order to make the first end 11 of the housing 10 press tightly against the display module 60 and improve the waterproof performance of the sealing ring 113, the first end 11 of the housing 10 is provided with a number of second fixing holes 114. The second fixing holes 114 can be connected to the display module 60 by existing screws, bolts and other fasteners. When there are multiple second fixing holes 114, the multiple second fixing holes 114 are arranged around the connecting hole 111.

[0042] Example 2

[0043] Combination Figure 8 and Figure 9As shown, in order to solve the same technical problem, this embodiment provides a display device 100, including a display module 60, a display control box and a module cable plug 1 as described above. One end of the transmission cable 40 is connected to the display control box, and the other end of the transmission cable 40 is provided with a first terminal 41, which is connected to a second terminal 22 on the circuit board 20.

[0044] The first end 11 of the housing 10 is connected to the display module 60. The first fixing hole 1222 and the second fixing hole 114 are both connected to the display module 60 by existing screws so that the housing 10 is fastened to the display module 60. The pins 30 on the circuit board 20 are inserted into the slot 61 of the display module 60 to realize the electrical connection between the display module 60 and the display control box.

[0045] The sealing ring 113 prevents moisture from entering the connection between the pin 30 and the slot 61 through the gap between the head end 11 of the housing 10 and the display module 60, thus preventing corrosion of the pin 30 and the slot 61. The sealant injected into the mounting port 121 prevents external moisture from entering the interior of the housing 10, thus making the plug waterproof.

[0046] In summary, the housing 10 has a circuit board 20 inside, which has pins 30 for connecting to the display module 60. The pins 30 pass through the connection hole 111 at the front end 11 of the housing 10. The mounting port 121 at the rear end 12 of the housing 10 exposes the circuit board 20 to the outside. Installation and maintenance personnel can process and maintain the circuit board 20 through the mounting port 121. The installation and maintenance personnel can process the circuit board 20 according to the actual signal transmission requirements without the need to customize expensive aviation plugs. After processing and maintenance, sealant is injected into the mounting port 121. The sealant can prevent moisture from entering the housing 10 through the mounting port 121, thereby improving the waterproof performance of the plug.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
