[0079] Figure 1 This is a perspective view of an electronic device A1, a wire B1, and a wire auxiliary device 1 according to an embodiment of the present invention. Figure 2 for Figure 1 A three-dimensional view of the wire auxiliary device 1. Figure 3 for Figure 2 Exploded view of wire auxiliary device 1. Figure 4 for Figure 2A partial cross-sectional view of the housing 10. The electronic device A1 can be a network communication device, such as a router, wireless access point, network switch, personal computer, laptop computer, tablet computer, or server. In this embodiment, the electronic device A1 has a waterproof mechanism.

[0080] Electronic device A1 includes a housing A10, a circuit board A20, and an electrical connector A30. For clarity, the structure of the housing A10 is simplified, and... Figure 1 The top cover of housing A10 is not shown in the figure. Electronic device A1 may further include electronic components such as a power supply, processor, storage device, and memory, but these are not shown for simplicity. Circuit board A20 and electrical connector A30 are disposed within housing A10, with electrical connector A30 disposed on circuit board A20. Electrical connector A30 corresponds to and is separate from opening A11 in housing A10. Electrical connector A30 may be a network communication connector. In this embodiment, electrical connector A30 may be an RJ45 socket, but is not limited thereto.

[0081] Cable B1 includes a plug B10 and a signal wire B20. Plug B10 is connected to signal wire B20. In this embodiment, plug B10 may be an RJ45 plug. Cable auxiliary device 1 is disposed within electronic device A1 and located between opening A11 and electrical connector A30. Plug B10 can pass through opening A11 of housing 10 and cable auxiliary device 1 into electrical connector A30. Since electrical connector A30 is separate from opening A11, cable auxiliary device 1 assists the user in accurately inserting plug B10 into electrical connector A30. Furthermore, cable auxiliary device 1 assists the user in disengaging plug B10 from electrical connector A30.

[0082] The wire auxiliary device 1 includes a housing 10, a clamping member 20, a moving member 30, a latch 40, a pull ring 50, a main elastic element 60, and an outer elastic element 70. The housing 10 may be a hollow structure and may extend along a moving direction D1. The housing 10 is adjacent to the electrical connector A30. The housing 10 includes a top plate 11, a bottom plate 12, two side walls 13, a front side plate 14, two first protrusions 15, and two limiting blocks 16. The top plate 11 is parallel to the bottom plate 12 and separate from the bottom plate 12. The two side walls 13 are perpendicular to the top plate 11 and the bottom plate 12. The two side walls 13 may be parallel to each other and may be separate from each other. The top plate 11, the bottom plate 12, and the side walls 13 may extend along the moving direction D1. The front side plate 14 is connected to the edges of the top plate 11, the bottom plate 12, and the side walls 13. The front side plate 14 may extend perpendicular to the moving direction D1.

[0083] Each of the two side walls 13 has a first limiting groove 131 and a first guiding groove 132. The first limiting groove 131 extends along the moving direction D1. The first guiding groove 132 is located above the first limiting groove 131. The front side plate 14 has a front opening 141. Two first protrusions 15 are located inside the housing 10 and are respectively disposed on the inner side of the two side walls 13. One first protrusion 15 can face the other first protrusion 15. In addition, two limiting blocks 16 are respectively disposed on the outer side of the two side walls 13. In this embodiment, each of the two side walls 13 has a connecting groove 135. The circuit board A20 can be inserted into the connecting groove 135 to engage with the housing 10.

[0084] The clamping member 20 is movably disposed within the housing 10. The plug B10 of the wire B1 passes through the clamping member 20 and is inserted into the electrical connector A30. In this embodiment, the clamping member 20 is movable relative to the housing 10 along the movement direction D1. The clamping member 20 includes a base 21, two clamping arms 22, two second protrusions 23, and two limiting posts 24. The base 21 has a channel 211 extending along the movement direction D1 and penetrating the base 21. The plug B10 can pass through the channel 211 and be inserted into the electrical connector A30. When the clamping member 20 moves to a clamping position, the base 21 can contact the front side plate 14, and the channel 211 can communicate with the front opening 141. The two clamping arms 22 are connected to the base 21 and can extend along the movement direction D1. The two clamping arms 22 can be arranged in parallel and are separated from each other. The two second protrusions 23 are respectively disposed on the outer side and free end of the two clamping arms 22. The first protrusion 15 of the housing 10 pushes the second protrusion 23, so that the two clamping arms 22 move toward the plug B10 to clamp the plug B10.

[0085] In this embodiment, each of the two clamping arms 22 has a clamping block 221 located on the inner side and free end of the clamping arm 22. The clamping block 221 faces the central axis of the clamping member 20, and one clamping block 221 can face the other clamping block 221. The two clamping arms 22 move toward the central axis of the clamping member 20 so that the clamping block 221 clamps the plug B10. The aforementioned central axis extends along the moving direction D1.

[0086] The two limiting posts 24 are respectively connected to the two clamping arms 22 and pass through the first limiting groove 131 of the housing 10. Therefore, the limiting posts 24 restrict the clamping member 20 from moving relative to the housing 10 along the moving direction D1.

[0087] The movable member 30 is movably disposed on the housing 10, and the movable member 30 is movable relative to the housing 10 in the moving direction D1. By pulling the movable member 30, the clamping member 20 is moved so that the clamping arm 22 clamps the plug B10 and pulls the plug B10 out of the electrical connector A30.

[0088] In this embodiment, the movable member 30 may be a U-shaped structure, covering the top plate 11 and the two side walls 13 of the housing 10. The movable member 30 includes two limiting grooves 31, two second limiting grooves 32, and two second guiding grooves 33. The limiting grooves 31 extend along the moving direction D1. The two limiting blocks 16 of the housing 10 are respectively located within the two limiting grooves 31 of the movable member 30. Therefore, the limiting blocks 16 restrict the movable member 30 from moving relative to the housing 10 along the moving direction D1. The second limiting grooves 32 extend along the moving direction D1, and the second guiding grooves 33 extend along the vertical direction D2. The aforementioned vertical direction D2 is perpendicular to the moving direction D1.

[0089] The limiting post 24 is further located within the second limiting groove 32 of the aforementioned movable member 30. The limiting post 24 restricts the movement of the clamping member 20 and the movable member 30 relative to the housing 10 along the moving direction D1. In this embodiment, the length of the first limiting groove 131 is greater than the length of the aforementioned second limiting groove 32. The lengths of the first limiting groove 131 and the second limiting groove 32 are measured along the moving direction D1.

[0090] The latch 40 is movably disposed within the housing 10 for engaging the plug B10 inserted into the electrical connector A30. The latch 40 extends perpendicular to the direction of movement D1. Both ends of the latch 40 are located within two first guide grooves 132 of the housing 10 and two second guide grooves 33 of the moving member 30, respectively. In this embodiment, the first guide groove 132 includes a first section 133 and a second section 134. The first section 133 is inclined relative to the second section 134. The second section 134 is connected to the first section 133 and extends along the direction of movement D1. Furthermore, the second guide groove 33 extends along the vertical direction D2. Therefore, when the moving member 30 moves relative to the housing 10, the latch 40 can be moved along the direction of movement D1 and / or the vertical direction D2 by means of the first guide groove 132 and the second guide groove 33.

[0091] Pull ring 50 is connected to movable member 30 via connecting rope E1. Pull ring 50 is detachably mounted in opening A11 of housing A10. Plug B10 can pass through pull ring 50 and clamp 20 to be inserted into electrical connector A30. When pull ring 50 is separated from housing A10, pull ring 50 is located outside housing A10. At this time, movable member 30 can be moved in the movement direction D1 by pulling pull ring 50.

[0092] The two ends of the main elastic element 60 are connected to the housing 10 and the clamping member 20. The main elastic element 60 provides a thrust to hold the clamping member 20 in an initial position. In this embodiment, the main elastic element 60 may be a spring. The main elastic element 60 is located inside the housing 10 and abuts against the front side plate 14 and the base 21 of the housing 10.

[0093] The two ends of the external elastic element 70 are connected to the housing 10 and the movable member 30. The external elastic element 70 provides tension to maintain the movable member 30 in its initial position. In this embodiment, the external elastic element 70 may be a spring. The housing 10 further includes a first hook 17 disposed on the top plate 11 and adjacent to the front side plate 14. The movable member 30 further includes a second hook 34. The two ends of the external elastic element 70 are respectively disposed on the first hook 17 and the second hook 34.

[0094] In this embodiment, the cable auxiliary device 1 may further include a first waterproof cover 80 and a second waterproof cover 90. The first waterproof cover 80 is installed in the opening A11 of the housing A10 and covers the pull ring 50 installed in the opening A11. The second waterproof cover 90 is installed on the first waterproof cover 80. The cable B1 passes through the first waterproof cover 80 and the second waterproof cover 90. The first waterproof cover 80 and the second waterproof cover 90 prevent liquids such as water from flowing into the housing A10 through the opening A11.

[0095] Figure 5A as well as Figure 5B This is a cross-sectional view of the method of using the wire auxiliary device 1 according to an embodiment of the present invention during the first process. Figure 2 , Figure 5A as well as Figure 5B As shown, the movable member 30 and the clamping member 20 are in an initial position, and the pull ring 50 can be installed on... Figure 1 The plug B10 is located inside the opening A11 of the housing A10. The plug B10 is located inside the housing 10, inserted into and electrically connected to the electrical connector A30. Additionally, the signal line B20 passes through the pull ring 50.

[0096] The latch 40 is located at the top of the first section 133 of the first guide groove 132 and at the top of the second guide groove 33. The latch A31 of the electrical connector A30 engages with the latch B11 of the plug B10. The latch 40 is located above the latch B11. In addition, the limiting post 24 is located at the first end of the second limiting groove 32. In this embodiment, the first end of the second limiting groove 32 is closer to the front opening 141 of the front side plate 14 than the second end of the second limiting groove 32. The second protrusion 23 contacts the side wall 13 of the housing 10. In other words, the first protrusion 15 of the housing 10 does not abut against the second protrusion 23 and does not push the second protrusion 23 to move.

[0097] Figure 6A This is a side view of the second process of using the wire auxiliary device 1 according to an embodiment of the present invention. Figure 6B This is a cross-sectional view of the second process of using the wire auxiliary device 1 according to an embodiment of the present invention. Figure 6A as well as Figure 6BAs shown, the movable member 30 is in a released position, while the clamping member 20 remains in the initial position. The user can separate the pull ring 50 from the opening A11 of the housing A10 and pull the pull ring 50 to move the movable member 30 from the initial position to the released position. The limiting post 24 moves from the first end to the second end of the second limiting groove 32. Therefore, the movable member 30 does not move the clamping member 20.

[0098] When the moving member 30 moves from the initial position to the release position along the moving direction D1, the moving member 30 drives the latch 40 of the second guide groove 33 to move from the top of the first section 133 of the first guide groove 132 to the bottom of the first section 133. Furthermore, through the inclined first guide groove 132, the latch 40 moves from the top of the second guide groove 33 to the bottom of the second guide groove 33. In other words, when the moving member 30 is in the release position, the latch 40 is located at the bottom of the first section 133 of the first guide groove 132 and at the bottom of the second guide groove 33. The latch 40 moves obliquely along the moving direction D1 and the vertical direction D2 and presses the latch B11 of the plug B10, thereby causing the latch B11 of the plug B10 to disengage from the locking block A31 of the electrical connector A30.

[0099] Figure 7A This is a side view of the third process of using the wire auxiliary device 1 according to an embodiment of the present invention. Figure 7B This is a cross-sectional view of the method of using the wire auxiliary device 1 according to an embodiment of the present invention in the third process. Figure 7A as well as Figure 7B As shown, the movable member 30 and the clamping member 20 are in a clamping position. The user can continuously pull the pull ring 50 to move the movable member 30 from the release position to the clamping position. At this time, the movable member 30 moves the limiting post 24 located at the second end of the second limiting groove 32, so that the clamping member 20 moves to the clamping position along the moving direction D1. At this time, the latch 40 moves to one end of the second section 134 of the second guide groove 33.

[0100] When the movable member 30 moves from the release position to the clamping position along the moving direction D1, the clamping member 20 moves along the moving direction D1, such that the second protrusion 23 abuts against the first protrusion 15 in a direction perpendicular to the moving direction D1. In other words, during the process of the clamping arm 22 clamping the plug B10, the two first protrusions 15 push the two second protrusions 23 so that the two clamping arms 22 clamp the plug B10.

[0101] After the two clamping arms 22 clamp the plug B10, the user continues to pull the pull ring 50 to move the clamping member 20, thereby moving the plug B10 relative to the electrical connector A30. The user can then release the pull ring 50, and the main elastic element 60 and the outer elastic element 70 will return the moving member 30 and the clamping member 20 to their initial positions. The user can then pull the plug B10 out of the electrical connector A30 and the housing A10.

[0102] In summary, the cable assist device 1 of the present invention allows cable B1 to be directly inserted into electrical connector A30 inside housing A10, and cable B1 to be pulled out from electrical connector A30 via the cable assist device 1. Therefore, using the cable assist device 1 of the present invention eliminates the need for adapter cables to connect to electrical connector A30 inside housing A10, thereby reducing the manufacturing cost of waterproof electronic devices.

[0103] For those skilled in the art, other corresponding changes or adjustments can be made based on the creative scheme and concept of the present invention in combination with the actual needs generated, and such changes and adjustments should all fall within the protection scope of the claims of the present invention.
