Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically to a board-to-board standard connector. Background Technology

[0002] A connector is a connecting device that sequentially connects multiple signal lines or power lines. It is an indispensable component in electronic equipment, widely used in various electrical circuits to connect or disconnect circuits. In the display industry, existing LED display array connectors come in numerous models and sizes, making selection difficult during LED display array design and hindering automated installation. Furthermore, while existing LED display array connectors offer both power and signal transmission capabilities, their rated current is relatively low, failing to meet the demands of future higher-power screens. After installation, LED display arrays often experience screen flickering due to vibrations (frequently occurring during stage performances, outdoor winds, etc.), affecting the viewing experience. Therefore, there is a need for a simple, stable board-to-board standard connector. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel board-to-board standard connector to solve the problem of unstable connections in existing connectors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A standard board-to-board connector for reliably connecting LED display arrays includes a first connector and a second connector. The first connector consists of a matching male connector and a female connector. The male connector includes a male base, a first terminal, a second terminal, and a third terminal. The first terminal is located in the middle of the male base. There are multiple second and third terminals, which are symmetrically arranged on both sides of the first terminal. The third terminal is located on the side of the second terminal away from the first terminal. The height of the second terminal, the third terminal, and the first terminal decreases sequentially. The connector includes a female end body, a fourth terminal, a fifth terminal, and a sixth terminal. The fourth terminal is located in the middle of the female end body. There are multiple fifth and sixth terminals, which are symmetrically arranged on both sides of the fourth terminal. The sixth terminal is located outside the fifth terminal. The first terminal is connected to the fourth terminal, the second terminal is connected to the fifth terminal, and the third terminal is connected to the sixth terminal.

[0005] Furthermore, the end of the male terminal body that engages with the female terminal body is the engagement end, and the other end opposite to the engagement end is the connection end. One end of the first terminal, the second terminal, and the third terminal all extend toward the connection end of the male terminal body and protrude beyond the connection end of the male terminal body, and are bent to form pins.

[0006] Furthermore, the female end body is provided with multiple sockets, and the fourth terminal, the fifth terminal and the sixth terminal are respectively disposed in the corresponding sockets.

[0007] Furthermore, the end of the fourth terminal near the joint end of the female end seat is bent inward to form a connection contact point.

[0008] Furthermore, both the fifth and sixth terminals consist of two electrodes, and the portions of the two electrodes within their respective sockets are inclined inwards.

[0009] Furthermore, the distance between the two electrodes gradually decreases from the connecting end of the female end seat towards the joining end of the female end seat.

[0010] Furthermore, the male end seat has first positioning posts on both sides of its connecting end, and the female end seat has second positioning posts on both sides of its connecting end.

[0011] Furthermore, guide blocks are provided on both sides of the male end seat along its own height direction, and guide grooves adapted to the guide blocks are provided on both sides of the female end seat corresponding to the positions of the guide blocks.

[0012] Furthermore, both the male and female terminals are insulating plastic shells, the first and fourth terminals are signal terminals, the second and fifth terminals are grounding terminals, and the third and sixth terminals are power supply terminals.

[0013] Furthermore, the first connector and the second connector have the same structure, but the height of the first connector is less than the height of the second connector.

[0014] Compared to existing technologies, the advantages of this invention are that, by adopting the above-mentioned solution, the structure is simple and suitable for power and signal port connections between LED display array transmission circuit boards. The first and fourth terminals are signal terminals, the second and fifth terminals are grounding terminals, and the third and sixth terminals are power terminals. When the male and female connectors are inserted, the grounding terminals connect first, followed by the power terminals for power conduction, and then the signal terminals for signal connection. This effectively reduces electrical sparks caused by tip discharge when the connectors are close together. The inward bending of the signal terminals on the female connectors increases the connection reliability when they connect with the signal terminals on the male connectors. The inwardly extending contact surfaces of the grounding and power terminals on the female connectors increase the contact area between the male and female terminals when they connect with the grounding and power terminals on the male connectors, thereby increasing the rated operating current of the power terminals and making it highly valuable for market applications.

When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "mounted," "fixed," "left side," "right side," and similar expressions used in this specification are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0019] One embodiment of this utility model is as follows: Figure 1 , 2 As shown, this board-to-board standard connector is used to reliably connect LED display arrays. It includes a first connector 1 and a second connector 2. The first connector 1 consists of a matching male connector 3 and a female connector 4. The male connector 3 includes a male terminal body 31, a first terminal 32, a second terminal 33, and a third terminal 34. The first terminal 32 is located in the middle of the male terminal body 31. There are multiple second terminals 33 and third terminals 34, which are symmetrically arranged on both sides of the first terminal 32. The third terminal 34 is located on the side of the second terminal 33 away from the first terminal 32. The height of the second terminal 33, the third terminal 34, and the first terminal 32 decreases sequentially. The connecting female connector 4 includes a female end body 41, a fourth terminal 42, a fifth terminal 43, and a sixth terminal 44. The fourth terminal 42 is located in the middle of the female end body 41. There are multiple fifth terminals 43 and sixth terminals 44, which are symmetrically arranged on both sides of the fourth terminal 42. The sixth terminal 44 is located outside the fifth terminal 43. The first terminal 32 is connected to the fourth terminal 42, the second terminal 33 is connected to the fifth terminal 43, and the third terminal 34 is connected to the sixth terminal 44.

[0020] The board-to-board standard connector of this solution is suitable for power and signal port connection between LED display array transmission circuit boards. The first terminal 32 and the fourth terminal 42 are signal terminals, the second terminal 33 and the fifth terminal 43 are ground terminals, and the third terminal 34 and the sixth terminal 44 are power terminals. When the male connector 31 and the female connector 41 are inserted, the ground terminal is connected first, followed by the power terminal to conduct electricity, and then the signal terminal to connect the signal. This effectively reduces the electrical sparks caused by tip discharge when the connector is close to the ground. The inward bending of the signal terminals on the female connector 41 forms the contact point 45, which increases the connection reliability when mating with the signal terminals on the male connector 31. The inwardly extending contact sides of the grounding and power terminals on the female connector 41 increase the contact area between the male and female terminals when mating with the grounding and power terminals on the male connector 31, thereby increasing the rated operating current of the power terminals. The first connector 1 and the second connector 2 have different sizes, making them suitable for indoor and outdoor LED display arrays. By optimizing the selection of terminal materials, structural design, and surface treatment processes, the electrical performance of the connectors has been improved, effectively reducing the probability of poor contact.

[0021] In this embodiment, as Figure 4 As shown, the end of the male terminal 31 that engages with the female terminal 41 is the engagement end, and the other end opposite to the engagement end is the connection end. One end of the first terminal 32, the second terminal 33, and the third terminal 34 extends toward the connection end of the male terminal 31 and protrudes beyond the connection end of the male terminal 31, and is bent to form a pin 37.

[0022] Specifically, the upper end of the male connector 31 is engaged with the female connector 41 as the engagement end, and the lower end of the male connector 31 is connected to the circuit board as the connection end. The lower ends of the first terminal 32, the second terminal 33, and the third terminal 34 extend downward and pass through the lower end of the male connector 31, and their bottom ends are bent to form surface mount pins for easy connection.

[0023] In this embodiment, as Figure 6 As shown, the female end seat 41 is provided with a plurality of sockets 46, and the fourth terminal 42, the fifth terminal 43 and the sixth terminal 44 are respectively disposed in the corresponding sockets 46.

[0024] Specifically, the female terminal block 41 has sixteen evenly spaced sockets 46 in the middle, which are signal areas. There are sixteen fourth terminals 42, which are respectively inserted into the sixteen sockets 46 in the middle of the female terminal block 41. There are two sockets 46 on each side of the signal area, which are grounding areas. There are four fifth terminals 43, which are respectively inserted into the four sockets 46 in the grounding areas. There are two sockets 46 on each side of the two grounding areas, which are power areas. There are four sixth terminals 44, which are respectively inserted into the four sockets 46 in the power areas.

[0025] In this embodiment, as Figure 6 As shown, the end of the fourth terminal 42 near the joint end of the female end seat 41 is bent inward to form a connection contact point 45.

[0026] Specifically, the end of the fourth terminal 42 near the joint end of the female terminal 41 is bent inward within the corresponding socket 46 to form a connecting contact point 45. The fourth terminal 42 has a double-sided two-contact structure, which increases the connection reliability when docking with the signal terminal on the male terminal 31.

[0027] In this embodiment, as Figure 6 As shown, both the fifth terminal 43 and the sixth terminal 44 are composed of two electrodes, and the portions of the two electrodes within the corresponding sockets 46 are inclined inward.

[0028] Specifically, the ends of the fourth terminal 42, the fifth terminal 43, and the sixth terminal 44 near the connection end of the female terminal 41 all extend toward the connection end of the female terminal 41 and protrude from the connection end of the female terminal 41, forming a through-hole pin.

[0029] In this embodiment, as Figure 6 As shown, the distance between the two electrodes gradually decreases from the connecting end of the female end seat 41 toward the joining end of the female end seat 41.

[0030] Specifically, the distance between the portions of the two electrodes within the corresponding sockets 46 gradually decreases from the connecting end of the female end seat 41 toward the engaging end of the female end seat 41 to form an elastic contact side, which can increase the contact area with the second terminal 33 and the third terminal 34.

[0031] In this embodiment, as Figure 4 As shown, the male end seat 31 has a first positioning post 35 on both sides of the connecting end, and the female end seat 41 has a second positioning post 47 on both sides of the connecting end.

[0032] Specifically, a positioning post is provided on each of the left and right sides of the connection end between the male end seat 31 and the female end seat 41 to facilitate positioning with the circuit board.

[0033] In this embodiment, as Figure 7 As shown, guide blocks 36 are provided on both sides of the male end seat 31 along its own height direction, and guide grooves 48 adapted to the guide blocks 36 are provided on both sides of the female end seat 41 corresponding to the positions of the guide blocks 36.

[0034] Specifically, the male end seat 31 has a mating groove for accommodating the mating end of the female end seat 41. On the left and right sides of the mating groove, guide blocks 36 are provided that protrude inward along their own height direction. When the male end seat 31 and the female end seat 41 are inserted, the guide blocks 36 are inserted into the guide groove 48 to connect the male end seat 31 and the female end seat 41.

[0035] In this embodiment, as Figure 4 , 6 As shown, both the male terminal 31 and the female terminal 41 are insulating plastic shells. The first terminal 32 and the fourth terminal 42 are signal terminals, the second terminal 33 and the fifth terminal 43 are grounding terminals, and the third terminal 34 and the sixth terminal 44 are power supply terminals.

[0036] Specifically, the first terminal 32, the second terminal 33, the third terminal 34, the fourth terminal 42, the fifth terminal 43 and the sixth terminal 44 are made of copper alloy sheets. C19010 copper alloy can be selected as the terminal material, and different terminal structures are designed for the signal PIN and the power PIN.

[0037] In this embodiment, as Figure 1 , 3 As shown, the first connector 1 and the second connector 2 have the same structure, and the height of the first connector 1 is less than the height of the second connector 2.

[0038] Specifically, the first connector 1 has a mating height of 17mm and is an indoor connector for LED display arrays, while the second connector 2 has a mating height of 20.8mm and is an outdoor connector for LED display arrays. The first connector 1 is an indoor connector with an effective travel of 6.51mm; the second connector 2 is an outdoor connector with an effective travel of 9.31mm. The first connector 1 and the second connector 2 have different sizes and are suitable for both indoor and outdoor LED display arrays. By optimizing the selection of terminal materials, structural design, and surface treatment processes, the electrical performance of the connectors has been improved, effectively reducing the probability of poor contact.

[0039] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
