Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a rectangular steel ball locking push-pull self-locking connector. Background Art

[0002] As electronic devices continue to become more miniaturized and integrated, the performance requirements for electrical connectors are also growing. Traditional connectors typically use a plug-in / pull-out design or a button snap to achieve plugging and unplugging. While the plug-in / pull-out design is easy to operate, it has low reliability and is easily affected by external forces, leading to accidental separation of the connection and signal interruption. The button snap unlocking structure is easy to plug in and out and does not easily fall off, but it lacks waterproof performance, which can cause inconvenience in humid or underwater environments. In addition, the button snap operation process is relatively cumbersome, making it more difficult for users to use. Utility Model Content

[0003] In order to solve the problems in the above background technology, the utility model provides a rectangular steel ball locking push-pull self-locking connector.

[0004] The solution adopted by the utility model to solve its technical problems is: a rectangular steel ball locking push-pull self-locking connector, comprising a male connector and a female connector, the female connector comprising a female housing and a female port, the male connector comprising a male housing and a male port, the male housing comprising a plug-in end plugged into the female housing, a push-pull self-locking mechanism being provided between the male housing and the female housing, the push-pull self-locking mechanism comprising a radial through hole axially symmetrically arranged on the female housing, a ball lock body movably arranged in the radial through hole, a clamping groove provided at a position corresponding to the radial through hole on the outer wall of the plug-in end and matching the ball lock body, a movable housing sleeved outside the male housing and axially slidable along the male housing, and an elastic body provided between the movable housing and the male housing, the elastic body being able to push the movable housing to move toward the female housing and squeeze the ball lock body to be clamped in the clamping groove to form a lock, and a release area for unlocking being provided on the top of the inner wall of the movable housing.

[0005] By implementing this technical solution, the movable housing, under the action of spring force, maintains compression on the steel ball, ensuring that the ball is pressed into the retaining groove of the male housing, thereby ensuring a stable connection. When separation is required, the steel ball can be withdrawn from the retaining groove by overcoming the spring force, enabling quick insertion and removal. Both the male and female housings are made of aluminum alloy and, in conjunction with the movable housing, provide metal shielding as well as waterproof and dustproof properties.

[0006] Furthermore, the outer wall of the male end housing is provided with a first stop portion, and the inner wall of the movable housing is provided with a second stop portion for cooperating with the first stop portion to prevent the movable housing from separating from the male end housing.

[0007] By adopting the above technical solution, when the movable housing slides to a certain position, the first stop portion and the second stop portion abut against each other to prevent the movable housing from moving further, thereby preventing the movable housing from being separated from the connector male end due to spring force or manual pushing and pulling.

[0008] Furthermore, both ends of the radial through hole are narrowed inwardly to form anti-detachment portions for preventing the ball lock body from completely detaching from the radial through hole.

[0009] By adopting the above technical solution, the problem that the ball lock body may fall off during use is effectively solved.

[0010] Furthermore, a sealing ring is provided inside the female end housing for achieving waterproofing.

[0011] By adopting the above technical solution, moisture and dust can be effectively prevented from entering the connector, thereby protecting the electrical connection from the influence of water and dust.

[0012] Furthermore, the outer wall of the movable shell is provided with anti-slip grooves for facilitating pushing and pulling.

[0013] By adopting the above technical solution, the friction between the fingers and the movable shell can be increased, so that the user can push and pull conveniently.

[0014] Furthermore, the male port and the female port are USB interfaces, HDMI interfaces or TYPEC interfaces.

[0015] In summary, the beneficial effects of the present invention are as follows: By designing a push-pull self-locking mechanism on the connector, including a radial through hole, a ball lock body, a snap-in groove, a movable housing, and an elastomer, the present invention allows the user to easily complete the self-locking or unlocking operation by pushing and pulling the movable housing when the male and female ends of the connector are plugged in. This ensures that the connector will not easily come loose when subjected to external forces, and can be easily unlocked, thereby achieving quick plugging and unplugging. When the male and female ends of the connector remain connected and locked, the movable housing that can be externally sleeved on the connecting part of the two and is provided with a sealing ring, thereby achieving a metal shielding effect and waterproof and dustproof performance.

[0026] like Figures 1 to 5As shown, a rectangular steel ball locking push-pull self-locking connector includes a connector male end 1 and a connector female end 2, wherein the connector female end 2 includes a female end shell 21 and a female end port 22, and the connector male end 1 includes a male end shell 11 and a male end port 12, wherein the male end shell 11 of this embodiment includes a plug end 111 plugged into the female end shell 21, and a push-pull self-locking mechanism 3 is provided between the male end shell 11 and the female end shell 21, and the push-pull self-locking mechanism 3 includes a radial through hole 31 axially symmetrically arranged on the female end shell 21, and a movable radial through hole 31. 1, a ball lock body 32 in the outer wall of the plug end 111, a snap-in groove 33 provided at a position corresponding to the radial through hole 31 and matching the ball lock body 32, a movable housing 34 sleeved outside the male end housing 11 and slidable axially along the male end housing 11, and an elastic body 35 provided between the movable housing 34 and the male end housing 11, and the elastic body 35 can push the movable housing 34 to move toward the female end housing 21 and squeeze the ball lock body 32 to snap into the snap-in groove 33 to form a lock, and a release area 341 for unlocking is provided on the top of the inner wall of the movable housing 34.

[0027] The connector of this embodiment is a rectangular connector, and its male end housing 11 is designed as a plug-in end 111 near one end of the female end 2 of the connector. When it is fully inserted into the female end housing 21, the male end port 12 and the female end port 22 can be connected. A push-pull self-locking mechanism 3 is provided between the male end housing 11 and the female end housing 21 to ensure the stability and reliability of the connection. The push-pull self-locking mechanism 3 mainly includes the following parts: first, radial through holes 31 are symmetrically provided on both sides of the female end housing 21. These through holes are used to accommodate movable ball lock bodies 32. The ball lock bodies 32 can move freely in the radial through holes 31. In this embodiment, they are steel balls, but they can also be ceramic balls or balls made of other materials. Secondly, on the outer wall of the plug-in end 111 of the male end housing 11, a snap-in groove 33 that matches the ball lock body 32 is provided at the position corresponding to the radial through hole 31. In addition, to achieve the push-pull self-locking function, a movable housing 34 is provided. The housing is mounted on the outside of the male housing 11 and can slide along the axial direction of the male housing 11. A rectangular spring is provided between the movable housing 34 and the male housing 11 as an elastic member, which can provide elastic force to drive the movable housing 34 to move toward the female housing 21 and cause the inner wall of the movable housing 34 to press the steel ball, causing the steel ball to move downward along the radial through hole 31 and snap into the snap groove 33. Because the spring rebound force always exists and cooperates with the retaining ring on the outer wall of the female housing 21, the movable housing 34 can be maintained in a default position. In this position, the steel ball is kept pressed into the snap groove 33, ensuring a stable connection between the male housing 11 and the female housing 21. When the connector needs to be separated, a release area 341 is provided on the top area of ​​the movable housing 34 near the female housing 21. The inner wall of this area is thinner than the inner wall of other areas, which can overcome the spring force to push the movable housing 34, allowing the steel ball to withdraw from the engaging groove 33 to achieve unlocking, thereby easily removing the male end 1 of the connector, achieving quick plug-in and plug-out as well as blind plug-in. In addition, both the male end housing 11 and the female end housing 21 are made of aluminum alloy. When the male end 1 and the female end of the connector remain connected and locked, the movable housing 34 can be externally sleeved on the connecting portion of the two. In this embodiment, the Type-C port is made of metal, which can achieve a double metal shielding effect. The movable housing 34 covers the connecting portion and also ensures good waterproof and dustproof performance.

[0028] like Figure 2As shown, in this embodiment, a first stop portion 112 is provided on the outer wall of the male housing 11, and a second stop portion 342 is provided on the inner wall of the movable housing 34 to cooperate with the first stop portion 112 to prevent the movable housing 34 from separating from the male housing 11. The first stop portion 112 is a protrusion formed around the outer wall of the male housing 11, while the second stop portion 342 is a protrusion formed around the middle of the inner wall of the movable housing 34. When the movable housing 34 slides to a certain position, the two parts will abut against each other, preventing further movement. This prevents the movable housing 34 from separating from the connector male end 1 due to spring force or manual pushing or pulling.

[0029] like Figure 2 As shown, the radial through hole 31 of this embodiment tapers inward at both ends to form anti-slip features 311, which prevent the ball lock body 32 from completely escaping from the radial through hole 31. Specifically, the ends of the radial through hole 31 gradually taper inward, forming an area with a diameter smaller than that of the ball lock body 32. When the ball lock body 32 reaches the end of the radial through hole 31, it is blocked by the anti-slip features 311, preventing it from moving further and falling out of the hole. During normal operation, the ball lock body 32 can move freely within the radial through hole 31, but is always restrained by the anti-slip features 311.

[0030] like Figure 2 and Figure 4 As shown, the female housing 21 of this embodiment is equipped with a sealing ring 4 for waterproofing. This effectively prevents moisture and dust from entering the connector, protecting the electrical connection during mating from water and dust interference. Furthermore, glue potting at the rear of the header ensures panel waterproofing, achieving IP68-level protection.

[0031] like Figure 5 As shown, the outer wall of the movable housing 34 of this embodiment is provided with anti-slip grooves 343 to facilitate pushing and pulling. These anti-slip grooves 343 are evenly distributed protrusions on the outer wall of the movable housing 34, and can also be other types of textures such as grooves. They increase the friction between the fingers and the movable housing 34, making it easier for the user to apply force to push and pull operations.

[0032] Furthermore, the male port 12 and the female port 22 of this embodiment are USB, HDMI, or Type-C interfaces. The male port 12 and the female port 22 can be any of a variety of different interfaces, including but not limited to USB, HDMI, and Type-C interfaces. These interfaces are widely used in modern electronic devices and can meet the connection requirements between different devices.

[0033] In summary, the beneficial effects of this embodiment are as follows: By adding a push-pull self-locking mechanism 3 composed of a radial through hole 31, a ball lock body 32, a snap-in groove 33, a movable housing 34, and an elastic body 35 to the connector, this embodiment can achieve self-locking or unlocking operations by pushing and pulling the movable housing 34 when the male and female ends of the connector are plugged together, ensuring that the connector will not easily loosen when subjected to external forces and allowing for easy unlocking for quick plugging and unplugging. When the male and female ends of the connector remain connected and locked, the movable housing 34, which can be externally sleeved onto the connecting portion of the two, is provided with a sealing ring 4, achieving a metal shielding effect and waterproof and dustproof properties.

[0034] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
