The holding arms 24 are disposed around the through hole 25, one end of each holding arm 24 is connected to the second connecting portion 23, the other end is a movable end, and an oblique notch 29 is disposed between any two adjacent holding arms 24, so that each holding arm 24 has an elastic force on the second connecting portion 23 and using the second connecting portion 23 as a fulcrum.
The sealing assembly 30 has a first sealing portion 31, a second sealing portion 32 spaced apart from the first sealing portion 31, and a connecting portion 33 connecting the first sealing portion 31 and the second sealing portion 32. The first sealing portion 31 is located on the first side 211 of the main body portion 21 and is disposed around the first connecting portion 22. The second sealing portion 32 is located inside the holding arms 24, and forms a gap 34 with the holding arms 24, and the second sealing portion 32 has a binding opening 35 therein communicating with the communication hole 25. The connecting portion 33 is disposed inside the through hole 27, and is connected to the first connecting portion 22 at the first side 211, and is connected to the second connecting portion 23 at the platform 26, so that the sealing assembly 30 can be reliably disposed on the main body 20, and the second connecting portion 23 is disposed at a position opposite to the first engaging portions 28 in the direction of the platform 26, and is provided with a plurality of second engaging portions 36 corresponding to the first engaging portions 28, and each second engaging portion 36 is respectively engaged with each first engaging portion 28. It should be noted that, in the present embodiment, the sealing element 30 is directly formed on the body 20 by an injection molding method, that is, after the body 20 is formed, the body 20 is placed into a mold (not shown), and then a liquid silicone rubber is injected into the mold, and after the liquid silicone rubber is cooled and solidified in the mold, the sealing element 30 is formed on the body 20.
The adjusting member 40 is disposed outside the second connecting portion 23 and covers the clamping arms 24, a chamber 41 for accommodating the second connecting portion 23 and the clamping arms 24 is disposed inside the adjusting member 40, and internal threads corresponding to the external threads of the second connecting portion 23 are disposed inside the chamber 41, so that the adjusting member 40 can be screwed on the second connecting portion 23. The adjusting member 40 further has a threading hole 42 penetrating through the adjusting member 40 and communicating with the accommodating chamber 41, a first guide surface 43 extending from the accommodating chamber 41 toward the threading hole 42 and a second guide surface 44 connected between the first guide surface 43 and the threading hole 42 are formed between the accommodating chamber 41 and the threading hole 42, the first guide surface 43 is provided with a plurality of oblique protrusions 45 corresponding to the oblique notches 29, and the second guide surface 44 is provided with a plurality of tightening protrusions 46 protruding toward the accommodating chamber 41. And the first guide surface and the second guide surface are inclined surfaces with different inclinations.
As shown in fig. 5 to 7, when the adjusting member 40 is assembled on the second connecting portion 23 of the body 20, the inner screw thread and the outer screw thread are assembled by screwing each other, so that the adjusting member 40 can have a first moving state moving toward the first connecting portion 22 on the second connecting portion 23 and a second moving state moving toward the holding arms 34 on the second connecting portion 23.
When the adjusting member 40 performs the first movement state on the second connecting portion 23, the adjusting member 40 will move toward the first connecting portion 22, so that the clamping arms 34 are guided by the first guiding surface 43 in the accommodating chamber 41 of the adjusting member 40, and the end of each clamping arm 24 pushes toward the second sealing portion 32, and compresses the second sealing portion 32, so that the restriction 35 in the second sealing portion 32 gradually forms a tight state, and the aperture of the restriction 35 gradually decreases. Since each of the oblique protrusions 45 protrudes into the oblique notch 29 between two adjacent clamping arms 24, when the adjusting member 40 is adjusted to a proper position, the oblique protrusions 45 can form a stop function for the clamping arms 24, thereby preventing the adjusting member 40 from being reversed on the second connecting portion 23, and further effectively keeping the tightening opening 35 in the tightened state. In addition, when the clamping arms 24 pass through the second guiding surface 44, because the plurality of the pressing protrusions 46 are arranged on the second guiding surface 44, the clamping arms 24 passing through the pressing protrusions 46 generate larger pushing force on the second sealing part 32, so that the second sealing part 32 can increase the tightening force in the tightening state.
When the adjusting member 40 performs the second movement state on the second connecting portion 23, the adjusting member 40 will move towards the holding arms 24, so that each holding arm 24 gradually moves away from the first guiding surface 43, and at this moment, the pushing force of the adjusting member 40 on each holding arm 24 will gradually decrease, so that each holding arm 24 generates a resilient effect towards the direction away from the second sealing portion 32, and further the tightening opening 35 of the second sealing portion 32 gradually forms a non-tightening state from the tightening state, that is, when the adjusting member 40 performs the second movement state, the aperture of the tightening opening 35 will gradually increase, and further the non-tightening state is formed.
As shown in fig. 5 to 8, the cable holder 10 of the present invention is mainly used to fix a cable 50 to a junction box 60, and to prevent moisture or humidity from entering the interior of the junction box 60 through the cable 50 or the cable holder 10, which may cause short circuit or damage. The cable holder 10 of the present invention is mainly locked to the junction box 60 by the first connecting portion 22, and the cable 50 is extended from the inside of the junction box 60 to the outside of the cable holder 10 through the communicating hole 25 and the opening 35.
When the body 20 is locked on the junction box 60 by the first connecting portion 22, since the first sealing portion 31 is located on the first side 211 of the main body portion 21, the first sealing portion 31 can be clamped between the main body portion 21 and the junction box 60, and the larger the locking force of the first connecting portion 22 on the junction box 60, the better the sealing effect of the first sealing portion 31 between the main body portion 21 and the junction box 60, and therefore, moisture or humidity can be effectively prevented from entering the junction box 60 through the space between the first connecting portion 22 and the junction box 60.
After the cable 50 passes through the opening 35, the adjusting member 40 is used to perform the first motion state on the second connecting portion 22, so that the opening 35 of the second sealing portion 32 generates the tightening state for the cable 50, the second sealing portion 32 is pressed by the clamping arms 24, the cable 50 is tightly covered, and the moisture or the humidity can be effectively prevented from entering the junction box 60 through the space between the cable 50 and the second sealing portion 32, so that the entire cable retaining device 10 has a good waterproof effect.
In addition, since the first sealing portion 31 and the second sealing portion 32 of the sealing assembly 30 are connected to each other by the connecting portion 33, a mutual restraining phenomenon can be formed between the first sealing portion 31 and the second sealing portion 32 through the connecting portion 33, and thus the first sealing portion 31 and the second sealing portion 32 can be effectively prevented from being separated from the first connecting portion 22 and the second connecting portion 23, respectively. Moreover, since the sealing assembly 30 is directly formed on the main body 20 by injection molding, the first sealing portion 31 and the second sealing portion 32 can be directly formed on the main body 20, so as to save the time for assembling the cable holding device 10 on the junction box 60, thereby improving the assembling efficiency of the cable holding device 10.
As shown in fig. 1 to 8, the first sealing portion 31 and the second sealing portion 32 of the sealing assembly 30 of the present invention are connected to each other by the connecting portion 33, so that the first sealing portion 31 and the second sealing portion 32 can be effectively prevented from falling off from the first connecting portion 22 and the second connecting portion 23, respectively, and meanwhile, the sealing assembly 30 is directly formed on the body 20, so that the sealing assembly 30 does not need to be installed separately during installation, and the assembly efficiency can be effectively improved. The adjusting member 40 extends into the inclined notch 29 through the inclined protrusions 45, so that the adjusting member 40 can be effectively prevented from loosening in the tightened state. Meanwhile, the urging protrusions 46 can effectively increase the pushing force of the holding arms 24 on the second sealing portion 32, so that the tightening opening 35 can generate a better tightening force.
In conclusion, the present invention has been made to meet the requirements of the patent application, and the patent application is made in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and therefore the scope of the claims of the present application is not limited thereto.
