[0002] Various electronic devices typically require external cables for transmitting electrical energy or signals. Traditionally, cables are secured to electronic devices by encasing the cable in a molded plastic body with a clip on it, which is then fastened to the device's casing. This is similar to the cable securing technology disclosed in patent CN118450656A. This technology, in addition to the traditional plastic body, uses adhesive to enhance the bond between the cable and the plastic body or to achieve waterproofing. However, this technical solution still suffers from problems inherent in traditional methods, such as insufficient cable fixation and susceptibility to loosening. Utility Model Content

[0007] Preferably, the upper and lower sides of the base portion extend rearward to form rear protrusions, each rear protrusion including a rear protrusion body extending rearward and an outwardly expanding portion expanding radially from the rear protrusion body. A transversely penetrating clearance space is formed behind the base portion and between the rear protrusions, and the connecting ring and the riveting ring are located within the clearance space.

[0008] Preferably, one end of the first connecting part is connected to the inner side of the rear protrusion, and the other end is connected to the connecting ring, and the first connecting part and the second connecting part are perpendicular to each other in projection.

[0009] Preferably, the front end of the base portion protrudes forward to form a forward protrusion, the perforation passes through the base portion and the forward protrusion, and the forward protrusion has a circular structure.

[0010] Preferably, the front protrusion is provided with a pair of positioning posts protruding forward and a fixing hole formed through the front protrusion. The fixing hole is used to fix the cable fixing device to the object by screws.

[0011] Preferably, a sealing ring is fitted around the outer periphery of the protruding part, and a fixing hole is formed through the outer periphery of the base part, which is used to fix the cable fixing device to the object by screws.

[0012] Preferably, the insulating shell includes an outer wall that covers the rear and outer periphery of the cable fixing device, a wire hole on the inner wall that fits tightly with the cable, and a protruding filling part that fills the perforation, and the clearance space is filled by the insulating shell.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0026] Please see Figure 1 As shown, the cable fixing device and cable assembly of this application are based on Figure 1 The X direction is the front end of the longitudinal direction, the Y direction is the lateral direction, and the Z direction is the vertical direction.

[0027] The cable assembly of this application includes a cable fixing device 20, a cable 10 riveted and fixed in the cable fixing device 20, and an insulating shell 30 formed and wrapped around the cable fixing device 20.

[0028] Please continue reading. Figures 2 to 5 As shown, the cable fixing device 20 of this application includes a base portion 21, a through hole 25 formed through the base portion 21, a connecting ring 23 formed in front of the base portion 21 and integrally connected to the base portion 21, and a riveting ring 24 formed in front of the connecting ring 23 and connected to the connecting ring 23. The cable fixing device 20 is manufactured by die casting process, and the material is aluminum alloy or magnesium alloy, etc.

[0029] The riveting ring 24 is connected to the connecting ring 23 via at least one second connecting portion 241, preferably a pair. An isolation space 29 is formed between the connecting ring 23 and the riveting ring 24, excluding the second connecting portions 241. This isolation space 29 allows a tool to be inserted between the riveting ring 24 and the connecting ring 23 to protect the connecting ring from deformation during riveting. After the cable 10 is inserted into the connecting ring 23 and the riveting ring 24 through the through hole 25, a riveting tool is used to wrap around and press the riveting ring 24, deforming it to clamp the cable 10. The riveting ring 24 is preferably deformed into a hexagonal structure to secure the cable 10. Initially, both the connecting ring 23 and the riveting ring 24 are rings with the same inner diameter.

[0030] The connecting ring 23 is connected to the base portion 21 via a first connecting portion 231, which is a pair of strip-shaped connecting bodies connected to the upper and lower sides of the connecting ring 23. The first connecting portion 231 partially suspends in front of the perforation 25 and eventually connects to the base portion 21 as a single unit. Alternatively, the first connecting portion 231 may extend obliquely rearward from the inner wall surface of the perforation 25.

[0031] The cable fixing device 20 of this application further includes rear protrusions 22 extending rearward from the upper and lower sides of the rear end of the base portion 21. Each rear protrusion 22 includes a rear protrusion body 221 extending rearward from the upper and lower ends of the base portion 21 and an outwardly expanding portion 222 expanding radially outward from the rear protrusion body 221. The outer diameter of the outwardly expanding portion 222 exceeds the outer diameters of the base portion 21 and the rear protrusion body 221. A transversely penetrating space S is formed behind the base portion 21 and between the pair of rear protrusions 22, and the connecting ring 23 and the riveting ring 24 are located within the penetrating space S. Further, the connecting ring 23 is connected to the rear protrusion 22 in the vertical direction via a first connecting portion 231, and a gap 28 exists between the connecting ring 23 and the rear end face of the base portion 21, allowing the connecting ring 23 to be suspended behind the base portion 21 via the first connecting portion 231. The first connecting portion 231 and the second connecting portion 241 are perpendicular to each other.

[0032] The front end of the base portion 21 of the cable fixing device 20 protrudes forward from the periphery of the through hole 25 to form a forward protrusion 26. A pair of positioning posts 212 extend forward from the front end of the forward protrusion 26, and at least a pair of fixing holes 211 are formed through the base portion 21 and the forward protrusion 26. A pair of fitting protrusions 213 protrude forward from the upper and lower sides of the front end face of the base portion 21.

[0033] After the cable 10 is inserted into the connecting ring 23 and the riveting ring 24 through the through hole 25, a riveting tool is inserted into the through space S from both sides laterally and presses the riveting ring 24 to deform and tighten the outer insulation layer of the cable 10. The riveting fixture can also extend into the isolation space 29 between the connecting ring 23 and the riveting ring 24 to protect the connecting ring 23 from deformation and maintain the accuracy of the cable 10's position. The projections of the connecting ring 23 and the riveting ring 24 in the longitudinal direction are located within the through hole 25.

[0034] The fixing hole 211 is used to fix the cable fixing device 20 to an object using screws or fasteners. The object can be the housing or component of an electronic or electrical device. The fixing hole 211 can effectively fix the cable 10 to the electronic or electrical device, such as an action camera, socket, plug, etc. The positioning post 212 cooperates with the corresponding positioning hole (not shown) on the object to achieve precise positioning. At the same time, the fitting protrusion 213 can also limit the corresponding structure on the object to prevent rotation. The front protrusion 26 is embedded in the recessed space (not shown) of the object to enhance the stability of the combination. There can be one or more objects that cooperate with the positioning post 212, fixing hole 211 and fitting protrusion 213.

[0035] Please continue reading. Figure 1 , Figure 2 , Figure 6 As shown, the insulating shell 30 is formed by injection molding onto the cable fixing device 20 after the cable 10 is riveted and fixed to it. The insulating shell 30 includes an outer wall 31 that wraps around the rear and outer periphery of the cable fixing device 20, a protruding filling portion 32 that fills the through hole 25, a wire hole 33 for the cable 10 to pass through, and a clearance portion 34 that avoids the protruding portion 26. The outer wall 31 includes a rear wall 311 that completely covers the rear of the cable fixing device 20, a first outer wall 312 that covers the lateral sides of the cable fixing device 20, and a second outer wall 313 that covers the upper and lower sides of the cable fixing device 20. The second outer wall 313 corresponds to and wraps around the rear protrusion 22 of the cable fixing device 20, and the second outer wall 313 is provided with a molding hole 314 to facilitate fixing the cable fixing device 20 during injection molding. The front end face of the insulating shell 30 is flush with the front end face of the base portion 21, and the front end face of the protruding filling portion 32 is flush with the front end face of the protruding portion 26.

[0036] The design of the rear protrusion 22 allows the cable 10 to be molded and fixed together with the insulating shell 30 over a relatively long distance, enhancing the bonding strength or waterproof performance.

[0037] Please continue reading. Figure 7 As shown, this application also provides an action camera, which includes a housing 40 and a cable assembly assembled and fixed on the housing 40. The cable assembly is fixed to the housing 40 of the action camera through the fixing hole 211 of the cable fixing device 20.

[0038] The mounting surface of the housing 40 is provided with a groove 41 that mates with the front protrusion 26. A sealing ring 50 is fitted around the outer periphery of the front protrusion 26. The sealing ring 50 is clamped between the outer periphery of the front protrusion 26 and the inner wall of the groove 41 to achieve a seal.

[0039] In one embodiment, the fixing hole 211 is provided on the base portion 21, that is, the fixing hole 211 is located on the periphery of the front protrusion 26, and a blind hole (not shown) is provided at the corresponding position of the housing 40. The cable assembly is locked in the blind hole of the housing 40 by screws to achieve good sealing performance.

[0040] The cable fixing device 20, cable assembly, and action camera of this application achieve good cable fixing by setting a suspended riveting ring 24 behind the base part 21 and fastening the cable 10 passing through it with the riveting ring 24; compared with the traditional technical solution of directly injection molding plastic material, it is more stable and reliable.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
