Description

Technical Field

[0001] The utility model relates to the technical field of plug connectors, and particularly relates to a plug connector. Background Art

[0002] Connectors are generally divided into two halves: a plug and a socket. The plug generally refers to the non-fixed half. A plug connector is a movable joint that is connected to a power-using device through a wire. The plug usually has protruding rod-shaped, blade-shaped and other forms of electrical contacts (referred to as male connectors) for plugging into the electrical contact slots of the socket (referred to as female connectors).

[0003] For example, an electrical connector with the publication number CN113540858B and the publication date of November 21, 2023, includes: an upper row of terminal components; a lower row of terminal components; a buckle member combined between the upper row of terminal components and the upper row of terminal components; an insulating kit formed with a docking space and an insertion port; the upper row of terminal components and the lower row of terminal components combined with the buckle member are assembled into the insulating kit. The buckle member extends to form a reinforcing foot, and the reinforcing foot extends in a transverse direction perpendicular to the insertion and extraction direction and exposes outside the insulating kit. There is a limiting effect between the reinforcing foot and the insulating kit.

[0004] In the above and in the prior art, there is usually no anti-detachment structure. When the connector body is accidentally touched or the wire is pulled, it is easy for the connector body to fall off the socket. And after falling off multiple times, when the connector body is connected to the socket, the connection will be very loose and easy to fall off automatically. Therefore, it is urgent to design a plug connector to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a plug connector to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A plug connector includes a connector body and a cover. Anti-detachment boxes are arranged on the outer walls on both sides of the connector body, and cavities are formed inside the anti-detachment boxes. A movable plate is slidably connected inside the cavities. A plug is integrally connected to the outer wall on one side of the movable plate. A slot is formed inside the anti-detachment box, and the plug is inserted into the slot. Guide rods are arranged on the inner walls of the cavities, and the movable plate is slidably sleeved outside the guide rods. Springs connected to the movable plate are arranged on the inner walls of the cavities, and the springs are sleeved outside the guide rods. A pressing block is arranged on the outer wall on one side of the movable plate, and the pressing block extends to the outside of the anti-detachment box. An anti-detachment block is inserted into the anti-detachment box, and the plug penetrates through the anti-detachment block.

[0008] Further, a limiting rod, a protective cover, and an electrical connecting rod are provided on the outer wall of the front surface of the connector body, and a wire is provided on the outer wall of the back surface of the connector body.

[0009] Further, the electrical connecting rod is located inside the protective cover, and the limiting rods are located on both sides of the protective cover.

[0010] Further, a rotating seat is provided on the outer wall of the top of the connector body, a rotating block is provided on the outer wall of the top of the retaining cover, and a dial plate is integrally connected to the outer wall of the rotating block.

[0011] Further, a rotating rod is provided on the inner wall of the rotating block, and the rotating rod is rotatably connected to the inside of the rotating seat through a bearing.

[0012] Further, circular cavities are provided on the outer walls of both sides of the connector body, and circular plates located inside the circular cavities are provided at both ends of the rotating rod.

[0013] Further, a torsion spring connected to the circular plate is provided on the inner wall of the circular cavity, and the torsion spring is sleeved on the outside of the rotating rod.

[0014] In the above technical solution, a plug connector provided by the present utility model

[0015] 1. By providing an anti-disconnection box, a cavity, a movable plate, a plug, a slot, a guide rod, a spring, a pressing block, and an anti-disconnection block, the anti-disconnection block is provided on the socket connected to the connector body. When the anti-disconnection block is inserted into the anti-disconnection box, it will push the plug to move, and the elastic force of the spring will push the movable plate and the plug to move, enabling the plug to penetrate through the anti-disconnection block and be inserted into the slot, thus connecting the connector body to the anti-disconnection block, and further connecting the connector body to the socket. This can prevent the connector body from being accidentally touched or the wire from being pulled, which may easily cause the connector body to fall off the socket. Moreover, it can avoid the problem that after the connector body falls off the socket multiple times due to its easy detachment, the connection between the connector body and the socket will become loose and prone to automatic detachment.

[0016] 2. By providing a protective cover, a rotating seat, a retaining cover, a rotating block, a dial plate, a rotating rod, a circular cavity, a circular plate, and a torsion spring, after the connector body is separated from the socket, the torsional force of the torsion spring will drive the circular plate to rotate, and the circular plate will drive the rotating rod, the rotating seat, and the retaining cover to rotate, causing the retaining cover to cover the outside of the protective cover, which can protect the electrical connecting rod. It can prevent water from splashing onto the electrical connecting rod, resulting in an electric connection when the connector body is connected to the socket, and can also prevent dust from adhering to the electrical connecting rod, causing poor contact.

[0017] 3. Through the provided limiting rod and protective cover, the limiting rod can be used to cooperate with the jack of an external socket to achieve the limiting function during insertion. The protective cover protects the electric connecting rod on its periphery and, in cooperation with the cover, has a good protective effect on the electric connecting rod.

[0026] As Figures 1-4As shown in the figure, a plug connector provided by an embodiment of the present invention includes a connector body 1 and a cover 15. Anti-disengagement boxes 2 are provided on the outer walls on both sides of the connector body 1, and a cavity 3 is formed inside the anti-disengagement box 2. A movable plate 4 is slidably connected inside the cavity 3, and a plug 5 is integrally connected to the outer wall on one side of the movable plate 4. A slot 6 is formed inside the anti-disengagement box 2, and the plug 5 is inserted into the slot 6. Guide rods 7 are provided on the inner wall of the cavity 3, and the movable plate 4 is slidably sleeved outside the guide rods 7. A spring 8 connected to the movable plate 4 is provided on the inner wall of the cavity 3, and the spring 8 is sleeved outside the guide rods 7. A pressing block 9 is provided on the outer wall on one side of the movable plate 4, and the pressing block 9 extends to the outside of the anti-disengagement box 2. An anti-disengagement block 22 is inserted into the anti-disengagement box 2, and the plug 5 passes through the anti-disengagement block 22.

[0027] A plug connector provided by the present invention includes a connector body 1 and a cover 15. Anti-disengagement boxes 2 are provided on the outer walls on both sides of the connector body 1, and a cavity 3 is formed inside the anti-disengagement box 2. A movable plate 4 is slidably connected inside the cavity 3, and a plug 5 is integrally connected to the outer wall on one side of the movable plate 4. A slot 6 is formed inside the anti-disengagement box 2, and the plug 5 is inserted into the slot 6. Guide rods 7 are provided on the inner wall of the cavity 3, and the movable plate 4 is slidably sleeved outside the guide rods 7. A spring 8 connected to the movable plate 4 is provided on the inner wall of the cavity 3, and the spring 8 is sleeved outside the guide rods 7. A pressing block 9 is provided on the outer wall on one side of the movable plate 4, and the pressing block 9 extends to the outside of the anti-disengagement box 2. An anti-disengagement block 22 is inserted into the anti-disengagement box 2, and the plug 5 passes through the anti-disengagement block 22. The anti-disengagement block 22 is used to be fixed on a socket connected to the connector body 1. When the connector body 1 is inserted into the socket, the anti-disengagement block 22 will be inserted into the anti-disengagement box 2. As the anti-disengagement block 22 is gradually inserted into the anti-disengagement box 2, the anti-disengagement block 22 will push the plug 5 to move, first squeezing the plug 5 into the cavity 3. When the slot 6 moves to the position of the plug 5, the elastic force of the spring 8 will push the movable plate 4 and the plug 5 to move, enabling the plug 5 to pass through the anti-disengagement block 22 and be inserted into the slot 6, so that the connector body 1 can be connected to the anti-disengagement block 22, and further enabling the connector body 1 to be connected to the socket, preventing the connector body 1 from falling off the socket and making the connection more secure.

[0028] By setting: the anti-dropping block 22 is set on the socket connected to the connector body 1, and when the anti-dropping block 22 is inserted into the anti-dropping box 2, it will push the plug block 5 to move, and the elastic force of the spring 8 will push the movable plate 4 and the plug block 5 to move, so that the plug block 5 can pass through the anti-dropping block 22 and be inserted into the inside of the slot 6, so that the connector body 1 can be connected with the anti-dropping block 22, and then the connector body 1 can be connected with the socket, which can prevent the connector body 1 from falling off from the socket when it is accidentally touched or the wire 13 is pulled, thereby avoiding the problem that the connector body 1 will be loosely connected to the socket and easily fall off automatically after falling off from the socket for many times due to the easy falling off of the connector body 1.

[0029] In one embodiment provided by the present utility model, Figure 2 As shown, a limit rod 10, a protective cover 11 and an electrical connection rod 12 are arranged on the outer wall of the front side of the connector body 1, and an electric wire 13 is arranged on the outer wall of the back side of the connector body 1. The protective cover 11 and the blocking cover 15 are used to protect the electrical connection rod 12.

[0030] In another embodiment provided by the present utility model, Figure 2 As shown, the electrical connection rod 12 is located inside the protective cover 11, and the limiting rods 10 are located on both sides of the protective cover 11. The limiting rods 10 can be used to cooperate with the sockets of the external socket to achieve the limiting function during plugging.

[0031] In another embodiment provided by the present utility model, Figure 1 and Figure 2 As shown, a rotating seat 14 is provided on the outer wall at the top of the connector body 1, a rotating block 16 is provided on the outer wall at the top of the blocking cover 15, and a shift plate 17 is integrally connected to the outer wall of the rotating block 16, through which the rotating block 16 and the blocking cover 15 can be rotated.

[0032] In one embodiment provided by the present utility model, Figure 2 and Figure 4 As shown, a rotating rod 18 is provided on the inner wall of the rotating block 16 , and the rotating rod 18 is rotatably connected to the inside of the rotating seat 14 through a bearing. When the rotating rod 18 rotates, it drives the rotating block 16 and the blocking cover 15 to rotate.

[0033] In another embodiment provided by the present utility model, Figure 4 As shown, circular cavities 19 are provided on the outer walls of both sides of the connector body 1 , and circular plates 20 located inside the circular cavities 19 are provided at both ends of the rotating rod 18 , and the circular plates 20 are used to connect with the torsion springs 21 .

[0034] In another embodiment provided by the present utility model, Figure 4As shown, a torsion spring 21 connected to the circular plate 20 is provided on the inner wall of the circular cavity 19, and the torsion spring 21 is sleeved on the outside of the rotating rod 18. The torsional force of the torsion spring 21 can drive the circular plate 20 and the rotating rod 18 to rotate, so that the rotating rod 18 drives the rotating block 16 and the blocking cover 15 to rotate, so that the blocking cover 15 blocks the outside of the protective cover 11 to protect the electrical connecting rod 12.

[0035] Working principle: first fix the anti-dropping block 22 on the socket connected to the connector body 1, and use the dial plate 17 to turn the rotating block 16 and the blocking cover 15 to rotate, so that the blocking cover 15 is flipped to the top of the connector body 1 and away from the protective cover 11, and the connector body 1 is plugged into the socket, and the anti-dropping block 22 will be plugged into the inside of the anti-dropping box 2. As the anti-dropping block 22 is gradually inserted into the inside of the anti-dropping box 2, the anti-dropping block 22 will push the plug-in block 5 to move, and first squeeze the plug-in block 5 into the inside of the cavity 3. When the slot 6 moves to the plug-in block 5, the elastic force of the spring 8 will push the movable plate 4 and the plug-in block 5 to move, so that the plug-in block 5 can pass through the anti-dropping block 22 and then be plugged into the inside of the slot 6, so that the connector body 1 can be connected with the anti-dropping block 22, and then the connector body 1 can be connected with the socket, which can prevent the connector body 1 from being accidentally touched or the wire 13 from being pulled, which can easily cause the connector body 1 to be detached from the socket. The problem of falling off is solved. The blocking cover 15 is released and the blocking cover 15 will be blocked above the socket. When the connector body 1 is to be separated from the socket, the pressing block 9 is pressed to drive the movable plate 4 and the plug block 5 to move, so that the plug block 5 is disengaged from the slot 6 and the anti-falling block 22, and the connector body 1 is pulled away from the socket and the anti-falling block 22. As the connector body 1 is separated from the socket, the blocking cover 15 is not subjected to force, and the torsional force of the torsion spring 21 will drive the circular plate 20 and the rotating rod 18 to rotate, and the rotating rod 18 will drive the rotating block 16 and the blocking cover 15 to rotate so that the blocking cover 15 is blocked outside the protective cover 11, which can prevent water from splashing onto the electrical connecting rod 12, causing electrical connection when the connector body 1 is connected to the socket, and can also prevent dust from adhering to the electrical connecting rod 12 and causing poor contact. The protective cover 11 and the blocking cover 15 cooperate to have a good protective effect on the electrical connecting rod 12.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
