Description

Technical Field

[0001] The utility model belongs to the technical field of orthogonal connectors, and specifically relates to an orthogonal connector structure. Background Art

[0002] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, various architecture servers emerge in an endless stream. Especially, the interconnection forms between boards are diverse. Among them, the orthogonal plug-in connector is a common interconnection connector. The orthogonal plug-in connector is a component designed to achieve stable and reliable connections between circuit boards or between a circuit board and a cable, and is particularly suitable for environments with limited space or high-density wiring. The characteristic of the orthogonal plug-in connector lies in that its contact design can ensure accurate docking in the vertical or nearly vertical direction (i.e., the orthogonal direction), thereby realizing efficient and stable signal transmission within a limited space.

[0003] The contact reliability of the orthogonal plug-in connector is crucial for ensuring the stability of data transmission and the long-term operation of the system. Especially in high-demand application environments such as cloud computing, big data processing, and artificial intelligence, any connection failure may lead to data loss, performance degradation, or even system interruption.

[0004] The plug-in connector is divided into a male end and a female end, which are respectively fixed on two boards by means of crimping or welding. The signal pins of the male end are elastic, and the contact points are in a convex shape, while the female end contact is in the form of a flat cuboid, providing a contact plane for the convex of the male end. When the male end is inserted, the pins of the male end will elastically press and contact with the pins of the female end to achieve signal connection.

[0005] However, the existing orthogonal plug-in connectors have contact risks. Due to the complex application scenarios of the orthogonal plug-in connectors, the male end pins of the connectors will experience high-frequency vibration, resulting in left and right offsets. When the amplitude is large, the male end pins and the female end pins will have a flash break, leading to abnormal signal states being transmitted. Summary of the Utility Model

[0006] To solve the problem that the existing orthogonal plug-in connectors have contact risks. Due to the complex application scenarios of the orthogonal plug-in connectors, the male end pins of the connectors will experience high-frequency vibration, resulting in left and right offsets. When the amplitude is large, the male end pins and the female end pins will have a flash break, leading to abnormal signal states being transmitted, the utility model provides an orthogonal connector structure.

[0007] The utility model is realized through the following technical solutions:

[0008] An orthogonal connector structure includes a first board and a second board arranged vertically; a plurality of male terminal signal pins bent at right angles are connected and installed on the first board, and a plurality of female terminal signal pins are connected and installed on the second board; a male terminal pin is provided at one end of the male terminal signal pin away from the first board, and a protrusion is provided on one side of the male terminal pin away from the first board; a female terminal pin is provided at one end of the female terminal signal pin away from the second board, and a concave arc surface capable of pressing and contacting the protrusion is provided on one side of the female terminal pin close to the first board.

[0009] A further improvement of the present utility model is that the male terminal pin is in the shape of a spherical protrusion.

[0010] A further improvement of the present utility model is that the female terminal pin is in an arc surface structure.

[0011] A further improvement of the present utility model is that a fillet or chamfer is provided on one side edge of the concave arc surface away from the female terminal signal pin.

[0012] A further improvement of the present utility model is that a tail section flush with the male terminal signal pin is provided at one end of the male terminal pin away from the male terminal signal pin.

[0013] A further improvement of the present utility model is that a fillet or chamfer is provided on one side edge of the tail section away from the male terminal signal pin and close to the protrusion.

[0014] A further improvement of the present utility model is that the male terminal pin is integrally formed by sheet metal stamping of the male terminal signal pin.

[0015] A further improvement of the present utility model is that the female terminal pin is integrally formed by sheet metal stamping of the female terminal signal pin.

[0016] A further improvement of the present utility model is that the width of the concave arc surface is 3 - 5 times the width of the male terminal pin.

[0017] A further improvement of the present utility model is that the width of the concave arc surface is 1.5 - 3 times the width of the female terminal pin.

[0018] From the above technical solutions, it can be seen that the beneficial effects of the present utility model are:

[0019] During use, the spherical protrusion of the male terminal pin has a pressing force on the concave arc surface of the female terminal pin (the male terminal signal pin has an elastic thrust to the right on the male terminal pin), so that the spherical protrusion and the concave arc surface have a reliable point contact, ensuring the continuity of the signal impedance; and when the male terminal pin undergoes high-frequency vibration (swinging back and forth), the concave arc surface limits the spherical protrusion (the greater the amplitude, the greater the pressing force at the limit position), which can effectively ensure the reliability and continuity of the connection (crimping) between the male terminal pin and the female terminal pin, avoid the flash-off phenomenon, and avoid abnormal transmission signal states.

[0027] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in this specific embodiment. Obviously, the embodiments described below are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0028] Such as Figures 1-5As shown in the figure, the utility model discloses an orthogonal connector structure, including a first board 1 and a second board 3 which are perpendicularly arranged, that is, as Figure 1 shown, the first board 1 is erected, and the second board 3 is horizontally arranged; a plurality of male terminal signal pins 2 bent at right angles are connected and installed on the right side of the first board 1. The first bent section of the male terminal signal pin 2 is perpendicularly arranged with the first board 1, and the second bent section of the male terminal signal pin 2 is erected and arranged downward; a plurality of erected female terminal signal pins 4 are connected and installed on the upper side of the second board 3; one end of the male terminal signal pin 2 far from the first board 1 (the lower end of the second bent section of the male terminal signal pin 2) is provided with a male terminal pin 21, and a spherical protrusion is arranged on the right side of the male terminal pin 21 far from the first board 1; one end of the female terminal signal pin 4 far from the second board 3 (the upper end) is provided with a female terminal pin 41, and a concave arc surface capable of contacting the protrusion at the pressing point is arranged on the side (left side) of the female terminal pin 41 close to the first board 1.

[0029] During use, the spherical protrusion of the male terminal pin 21 has a pressing force on the concave arc surface of the female terminal pin 41 (the male terminal signal pin 2 has an elastic pushing force to the right on the male terminal pin 21), so that the spherical protrusion and the concave arc surface have reliable point contact to ensure the continuity of signal impedance; and when the male terminal pin 21 has high-frequency vibration (swinging back and forth), the concave arc surface limits the spherical protrusion (the greater the amplitude, the greater the pressing force at the limit position), which can effectively ensure the reliability and continuity of the connection (crimping) between the male terminal pin 21 and the female terminal pin 41, avoid the flash-off phenomenon, and avoid the abnormal state of the transmitted signal.

[0030] Among them, as Figures 3-4 shown, the male terminal pin 21 is in a spherical protrusion shape (thin wall). The male terminal pin 21 is integrally formed by sheet metal stamping of the male terminal signal pin 2. It is light in weight and easy to form, realizing continuous and reliable point contact.

[0031] Among them, as Figure 5 shown, the female terminal pin 41 is in an arc surface structure. The female terminal pin 41 is integrally formed by sheet metal stamping of the female terminal signal pin 4. It is light in weight and easy to form, effectively realizing the vibration limit of the male terminal pin 21 and avoiding the flash-off phenomenon.

[0032] As Figures 4-5 shown, to ensure the smoothness of the insertion of the male terminal pin 21 and the female terminal pin 41, a fillet or chamfer is arranged on the side edge of the concave arc surface far from the female terminal signal pin 4, and a tail section flush with the second bent section of the male terminal signal pin 2 is arranged at one end of the male terminal pin 21 far from the male terminal signal pin 2. A fillet or chamfer is arranged on the side edge of the tail section far from the male terminal signal pin 2 and close to the protrusion. It plays an effective insertion guiding role.

[0033] Among them, the width of the concave arc surface is 3 - 5 times the width of the male terminal pin 21, ensuring the reliability of vibration limit for the male terminal pin 21.

[0034] Among them, the width of the concave arc surface is 1.5 - 3 times the width of the female terminal pin 41, achieving reliable vibration limit for the male terminal pin 21 and reducing the weight of the female terminal signal pin 4.

[0035] For this orthogonal connector structure, during use, the spherical protrusion of the male terminal pin 21 has a pressing force on the concave arc surface of the female terminal pin 41 (the male terminal signal pin 2 has an elastic thrust to the right on the male terminal pin 21), enabling a reliable point contact between the spherical protrusion and the concave arc surface and ensuring the continuity of signal impedance. Moreover, when the male terminal pin 21 undergoes high-frequency vibration (swinging back and forth), the concave arc surface limits the spherical protrusion (the greater the amplitude, the greater the pressing force at the limit position), effectively ensuring the reliability and continuity of the connection (crimping) between the male terminal pin 21 and the female terminal pin 41, avoiding flash-off phenomena and abnormal transmission signal states.
