Description

Technical Field

[0001] This utility model belongs to the field of wire anti-pull technology, and specifically relates to a wire anti-pull structure. Background Technology

[0002] Typically, electronic devices include a housing, wires, and a PCB board. The PCB board is housed inside the housing, which has through-holes. One end of the wire passes through these through-holes and is soldered to the PCB board inside the housing. When the wire is pulled, one end of the wire can easily break off from the PCB board, causing the wire to detach and preventing the electronic device from functioning properly.

[0003] Existing technology provides an anti-pull structure sleeved on the outer surface of a wire, the anti-pull structure being embedded in a through hole. When the wire is pulled, the anti-pull structure engages with the through hole, preventing one end of the wire from disconnecting from the PCB board and the wire from detaching from the PCB board.

[0004] However, existing technologies require customized anti-pull structures corresponding to the through-holes, which is costly. Furthermore, existing anti-pull structures cannot be securely attached to the wires, easily detaching and failing to achieve the intended anti-pull effect. Additionally, when the wire is pulled with significant force, the through-holes are easily damaged, causing the anti-pull structure to be pulled out. Utility Model Content

[0005] To address the aforementioned problems, the primary objective of this utility model is to provide an anti-pull structure for electrical wires, thereby resolving the technical issues described above.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a wire anti-pull structure, including a bottom shell, a wire and a PCB board. An arc-shaped limiting groove is provided inside the bottom shell. One end of the wire is electrically connected to the PCB board and the wire is embedded in the arc-shaped limiting groove to limit the wire.

[0008] Compared with existing technologies, the advantages of this invention are as follows: The wire is embedded in the arc-shaped limiting groove. When the wire is pulled, the arc-shaped limiting groove limits the wire, preventing one end of the wire from disconnecting from the PCB board. Simultaneously, the arc-shaped limiting groove disperses the pulling force. When the pulling force is large, the arc-shaped limiting groove disperses the pulling force, preventing damage to the groove and thus achieving a better anti-pull effect. Furthermore, compared to existing anti-pull structures that are sleeved on the outer surface of the wire, the arc-shaped limiting groove of this application can achieve a better fixed connection with the wire, thus achieving a better anti-pull effect. Moreover, the arc-shaped limiting groove of this application has a simple manufacturing process, low cost, and wider application range.

[0009] Furthermore, the arc-shaped limiting groove includes a first through hole and a second through hole. The wire enters the arc-shaped limiting groove through the first through hole and exits the arc-shaped limiting groove through the second through hole.

[0010] Furthermore, the arc-shaped limiting groove is circular in shape to achieve a better limiting effect.

[0011] Furthermore, a positioning post is provided in the arc-shaped limiting groove, and the wire is embedded in the arc-shaped limiting groove along the positioning post.

[0012] Furthermore, positioning holes are provided on the positioning posts, and corresponding positioning through holes are provided on the PCB board. The PCB board covers the arc-shaped limiting groove to press the wire embedded in the arc-shaped limiting groove. At the same time, the arc-shaped limiting groove and the PCB board form a limiting space to prevent the wire from coming out of the arc-shaped limiting groove, thereby better securing the wire within the arc-shaped limiting groove.

[0013] Preferably, the screw passes through the positioning through hole and is positioned inside the positioning hole to achieve a fixed connection between the PCB board and the positioning post. The PCB board covers the arc-shaped limiting groove to press the wire embedded in the arc-shaped limiting groove. At the same time, the arc-shaped limiting groove and the PCB board form a limiting space to prevent the wire from coming out of the arc-shaped limiting groove, thereby better securing the wire within the arc-shaped limiting groove.

[0014] Furthermore, a protrusion protrudes within the arc-shaped limiting groove, with one side of the wire abutting against the protrusion and the other side of the wire abutting against the PCB board, to better compress the wire embedded in the arc-shaped limiting groove.

[0015] Furthermore, the protrusions include a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion arranged vertically in sequence.

[0016] Furthermore, connection holes are provided on the inner surface of the bottom shell, and the PCB board has corresponding connection through holes to achieve a fixed connection between the PCB board and the bottom shell.

[0017] In some implementations, screws pass through connecting through holes and are positioned within connecting holes, while screws pass through positioning through holes and are positioned within positioning holes, to better secure the PCB board to the positioning post. The PCB board covers the arc-shaped limiting groove, pressing the wire embedded within the arc-shaped limiting groove firmly against it. Simultaneously, the arc-shaped limiting groove and the PCB board form a limiting space, preventing the wire from slipping out of the arc-shaped limiting groove, thus better securing the wire within it.

[0018] Compared with existing technologies, the advantages of this invention are as follows: The wire is embedded in the arc-shaped limiting groove. When the wire is pulled, the arc-shaped limiting groove limits the wire, preventing one end of the wire from disconnecting from the PCB board. Simultaneously, the arc-shaped limiting groove disperses the pulling force. When the pulling force is large, the arc-shaped limiting groove disperses the pulling force, preventing damage to the groove and thus achieving a better anti-pull effect. Furthermore, compared to existing anti-pull structures that are sleeved on the outer surface of the wire, the arc-shaped limiting groove of this application can achieve a better fixed connection with the wire, thus achieving a better anti-pull effect. Moreover, the arc-shaped limiting groove of this application has a simple manufacturing process, low cost, and wider application range. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] To achieve the above objectives, the technical solution of this utility model is as follows:

[0026] See Figures 1-4 As shown, this utility model provides a wire anti-pull structure, including a bottom shell 1, a wire 2 and a PCB board 3. An arc-shaped limiting groove 11 is provided inside the bottom shell 1. One end of the wire 2 is electrically connected to the PCB board 3. The wire 2 is embedded in the arc-shaped limiting groove 11 to limit the wire 2.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: the wire 2 is embedded in the arc-shaped limiting groove 11. When the wire 2 is pulled, the arc-shaped limiting groove 11 limits the wire 2, preventing one end of the wire 2 from disconnecting from the PCB board 3 when pulled. Simultaneously, the arc-shaped limiting groove 11 disperses the pulling force. When the pulling force on the wire 2 is large, the arc-shaped limiting groove 11 disperses the pulling force to prevent damage, thus achieving a better anti-pull effect. Furthermore, compared with the anti-pull structure sleeved on the outer surface of the wire 2 in the prior art, the arc-shaped limiting groove 11 of this application can better achieve a fixed connection with the wire 2, thereby better achieving the anti-pull effect. Moreover, the arc-shaped limiting groove 11 of this application has a simple manufacturing process, low cost, and wider application range.

[0028] In this embodiment, the arc-shaped limiting groove 11 includes a first through hole 111 and a second through hole 112. The wire 2 enters the arc-shaped limiting groove 11 through the first through hole 111 and exits the arc-shaped limiting groove 11 through the second through hole 112.

[0029] In this embodiment, the arc-shaped limiting groove 11 is circular in shape to achieve a better limiting effect.

[0030] In this embodiment, a positioning post 113 is provided in the arc-shaped limiting groove 11, and the wire 2 is embedded in the arc-shaped limiting groove 11 along the positioning post 113.

[0031] In this embodiment, a positioning hole 114 is provided on the positioning post 113, and a positioning through hole 31 is provided on the PCB board 3 corresponding to the positioning hole 114. The PCB board 3 covers the arc-shaped limiting groove 11 so as to press the wire 2 embedded in the arc-shaped limiting groove 11 tightly. At the same time, the arc-shaped limiting groove 11 and the PCB board 3 form a limiting space to prevent the wire 2 from coming out of the arc-shaped limiting groove 11, thereby better realizing the fixed embedding of the wire 2 in the arc-shaped limiting groove 11.

[0032] Preferably, the screw 5 passes through the positioning through hole 31 and is positioned within the positioning hole 114 to achieve a fixed connection between the PCB board 3 and the positioning post 113. The PCB board 3 covers the arc-shaped limiting groove 11 to press the wire 2 embedded in the arc-shaped limiting groove 11. At the same time, the arc-shaped limiting groove 11 and the PCB board 3 form a limiting space to prevent the wire 2 from coming out of the arc-shaped limiting groove 11, thereby better securing the wire 2 within the arc-shaped limiting groove 11.

[0033] In this embodiment, a protrusion 4 protrudes from the arc-shaped limiting groove 11. One side of the wire 2 abuts against the protrusion 4, and the other side of the wire 2 abuts against the PCB board 3, so as to better press the wire 2 embedded in the arc-shaped limiting groove 11.

[0034] In this embodiment, the protrusion 4 includes a first protrusion 41, a second protrusion 42, a third protrusion 43 and a fourth protrusion 44 arranged vertically in sequence.

[0035] In this embodiment, a connection hole 12 is also provided on the inner surface of the bottom shell 1, and the PCB board 3 is provided with a connection through hole 32 corresponding to the connection through hole 32, so as to realize the fixed connection between the PCB board 3 and the bottom shell 1.

[0036] In some embodiments, screw 5 passes through the connecting through hole 32 and is disposed within the connecting hole 12, and screw 5 passes through the positioning through hole 31 and is disposed within the positioning hole 114, so as to better achieve the fixed connection between PCB board 3 and positioning post 113. PCB board 3 covers the arc-shaped limiting groove 11, so as to press the wire 2 embedded in the arc-shaped limiting groove 11 by PCB board 3. At the same time, the arc-shaped limiting groove 11 and PCB board 3 form a limiting space to prevent the wire 2 from coming out of the arc-shaped limiting groove 11, thereby better achieving the fixed embedding of wire 2 in the arc-shaped limiting groove 11.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
