[0017] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 9 With the orientation as a reference, the direction where the male inner mold 11 is located is "up", and the direction where the female inner mold 25 is located is "down".

[0018] This utility model provides a signal and power connector for LED displays, including a female connector assembly and a male connector assembly, which are plugged together to provide power and signals to the LED display. The female connector assembly includes a busbar head housing, a female connector outer shell, a female connector inner mold, and a first power pin and a first signal pin fixedly installed on the female connector inner mold. The lower end of the female connector inner mold is fixedly connected to the busbar head housing, and the upper end of the female connector inner mold is fixedly fitted with the female connector outer shell. The female connector inner mold has two protective sockets. The first power pin is installed in the protective socket, and its height is lower than the top surface of the female connector inner mold. The male connector assembly includes a male connector inner mold, a second power pin and a second signal pin installed in the male connector inner mold, a male connector outer shell, and a male connector wire housing. The lower end face of the male connector inner mold has a protective post. The second power pin is installed in the protective post, and its height is lower than the end face of the protective post. The protective post is used to insert into the protective socket, so that the first power pin... One power pin is inserted into the second power pin. The upper end of the male inner mold is fixedly connected to the male wire housing. The male outer shell is rotatably sleeved on the male inner mold for insertion and locking into the female outer shell. Because a protective post is set on the male inner mold, the second power pin is hidden in the protective post. A protective socket is set on the female inner mold, so that the first power pin is hidden in the protective socket. This prevents the operator from accidentally touching the first and second power pins and prevents the first and second power pins from coming into contact with various conductive bodies due to improper operation. This greatly improves the safety protection performance of the connector and solves the technical problem that the safety protection performance of existing LED display connectors is not ideal compared with the existing technology.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] Example 1, refer to Figure 1 and Figure 4 This embodiment 1 provides a signal and power connector for LED displays, including a female connector assembly 2 and a male connector assembly 1, which are plugged into each other to provide power and signals to the LED display.

[0021] See Figure 1 , Figure 2 and Figure 7 The female connector assembly 2 includes a bus head housing 21, a female connector outer shell 22, a female connector inner mold 25, and a first power pin 23 and a first signal pin 24 fixedly installed on the female connector inner mold 25. The lower end of the female connector inner mold 25 is fixedly connected to the bus head housing 21, and the upper end of the female connector inner mold 25 is fixedly sleeved with the female connector outer shell 22. The female connector inner mold 25 has two protective sockets 251. The first power pin 23 is installed in the protective sockets 251, and its height is lower than the top surface of the female connector inner mold 25.

[0022] See Figures 4 to 6 The male connector assembly 1 includes a male inner mold 11, a second power pin 12 and a second signal pin 13 installed in the male inner mold 11, a male outer shell 14, and a male wire shell 15. The lower end face of the male inner mold 11 is provided with a protective post 113. The second power pin 12 is installed in the protective post 113, and its height is lower than the end face of the protective post 113. The protective post 113 is used to insert into the protective socket 251 so that the first power pin 23 and the second power pin 12 are connected. The upper end of the male inner mold 11 is fixedly connected to the male wire shell 15. The male outer shell 14 is rotatably sleeved on the male inner mold 11 and is used to insert into and lock in the female outer shell 22.

[0023] See Figure 1 A gap is provided between the female connector housing 22 and the female connector inner mold 25 to form a mating cavity 20 that fits the male connector housing 14. The inner wall of the female connector housing 22 is provided with a locking protrusion 222, and the lower outer wall of the male connector housing 14 is provided with a locking groove 141. The locking protrusion 222 is used to cooperate with the locking groove 141 to lock the male connector housing 14 and the female connector housing 22 together. The male connector housing 14 and the female connector housing 22 are locked together for waterproofing, and the outer wall of the protective post 113 is seamlessly fitted with the inner wall of the protective socket 251 for waterproofing. The double waterproof protection design prevents rainwater from contacting the first power pin 23 and the second power pin 12, thus enhancing safety.

[0024] In some feasible solutions, the outer wall of the protective post 113 is provided with an integrally formed annular sealing rib, the diameter of which is 0.05–0.1 mm larger than the inner diameter of the protective socket 251, forming an interference seal fit; the sealing rib is made of silicone rubber, which fills the micro gaps in the inner wall of the protective socket 251 under compression, achieving IP67 waterproof rating.

[0025] In some feasible solutions, the inner wall of the female head housing 22 is provided with at least two locking protrusions 222, each locking protrusion 222 being arranged along the inner wall of the female head housing 22 and symmetrically distributed. The number of locking grooves 141 is equal to the number of locking protrusions 222. The number of locking protrusions 222 is generally two, three, or four, depending on actual needs.

[0026] In some feasible solutions, the lower end of the female inner mold 25 is provided with a first partition plate 252 opposite to the protective socket 251. The first partition plate 252 is used to isolate the positive and negative pins. The upper end of the male inner mold 11 is provided with a second partition plate 111 opposite to the protective post 113. The second partition plate 111 is used to separate the positive and negative pins. The first partition plate 252 and the second partition plate 111 facilitate the wire bonding operation of the power pins and ensure that the two first power pins 23 do not come into contact with each other during use.

[0027] See Figure 5 and Figure 6 The male inner mold 11 has an annular protrusion in the middle as an alignment groove 112, and the annular protrusion has a notch in the circumferential direction. Correspondingly, the inner wall of the male outer shell 14 has a guide rib that mates with the notch. When the male outer shell 14 is rotated, the guide rib must align with the notch to pass through the annular protrusion and drive the male outer shell 14 to move axially until the locking groove 141 engages with the locking protrusion 222 to complete the locking. The notch also serves as the initial alignment mark for the locking indicator arrow 142.

[0028] See Figure 1 and Figure 5 The male head housing 14 is provided with a locking indicator arrow 142, and the female head housing 22 is provided with a matching locking mark.

[0029] See Figure 1 and Figure 2 The sliding unlock button 221 is elastically connected to the female connector housing 22 via a spring. Its inner protrusion is normally engaged in the slot of the male connector housing 14. Pushing the sliding unlock button 221 along the axial direction compresses the spring, causing the protrusion to exit the slot, and the male connector housing 14 can rotate freely to unlock. After being released, the spring returns to its original position, causing the protrusion to engage again.

[0030] See Figure 1 and Figure 5Both the first power pin 23 and the second power pin 12 have three pin bodies, including a positive pin, a negative pin, and a ground pin. The connector provides 220V or other preset voltage AC power to the LED display.

[0031] See Figure 1 and Figure 8 The upper ends of the positive and negative pins on the inner mold 25 of the female connector are tightly fitted together with the inner mold 25, i.e., with an interference fit, and their lower ends extend into the corresponding protective sockets 251. The inner mold 25 of the female connector also has multiple mounting through holes for tightly fitting the grounding pin and eight first signal pins 24. The first power pin 23 has a blind hole for inserting and engaging with the second power pin 12, and the first signal pin 24 has a blind hole for inserting and engaging with the second signal pin 13.

[0032] See Figure 9 Correspondingly, on the male inner mold 11, one end of the positive and negative electrodes are tightly fitted to the male inner mold 11, and the other ends extend into the corresponding protective post 113. The height of the positive and negative electrodes (second power pin 12) is less than the height of the protective post 113, and the protective post 113 does not exceed the plane of the lower end face of the male outer shell 14, thus achieving double safety protection. The second signal pin 13 is tightly fitted to the male inner mold 11, and its height is lower than the lower end face of the male outer shell 14, that is, it is located in the cavity formed by the lower end face of the male inner mold 11 and the male outer shell 14.

[0033] See Figure 2 The bus head housing 21 also includes a wire tail rubber-coated section 211 and a power and signal combo cable 212, all integrally molded using injection molding. The male head housing has a basically the same structure as the bus head housing 21. In actual production, the female head housing 22 can be injection molded with the female head inner mold 25, which is already equipped with the first power pin 23 and the first signal pin 24, and the bus head housing 21 can be injection molded with the female head inner mold 25, ultimately resulting in a complete female head assembly 2; similarly, the male head housing 14 and the male head inner mold 11, which is already equipped with the second power pin 12 and the second signal pin 13, can be injection molded with the male head housing, ultimately resulting in a complete male head assembly 1.
