Description

Technical Field

[0001] This utility model relates to the field of cable routing protection technology, and more specifically, to an edge protection ring for electrical cable routing. Background Technology

[0002] In industrial plants, building electrical systems, and various equipment internal wiring scenarios, metal cable trays are widely used for laying and protecting electrical cables due to their advantages of high structural strength, good wiring regularity, and effective support for multiple electrical cables. However, in practical applications, the ends of metal cable trays are usually cut and shaped, inevitably resulting in sharp edges and burrs. During the long-term use of electrical cables through the cable tray, slight displacement or during cable pulling operations during later maintenance can cause direct friction between the cable's outer insulation layer and the sharp edges of the metal cable tray ends. This can lead to insulation wear and cracking, shortening the cable's lifespan and potentially exposing the internal conductors, causing electrical safety hazards such as short circuits and leakage, threatening the normal operation of equipment and personnel safety.

[0003] A search revealed that Chinese patent CN205646676U discloses a multi-functional protective sleeve for metal wire troughs. This structure uses TPE elastomer injection molded parts that conform to the dimensions of metal profiles, resulting in a closer fit between the size and the profile. It completely covers the metal wire troughs, solving problems such as detachment, dead corners, unsightly appearance, and limitations.

[0004] However, this structure still has the following problems in practical use: 1. Because the embedded frame of this structure is a ring structure and is set vertically at the edge of the end face of the protective sleeve, and the embedded frame is fitted on the end of the metal wire channel, its fixation depends only on the tightness of the fit between the embedded frame and the wire channel. Under vibration or external force pulling, it is easy to loosen and shift, and it is difficult to maintain a stable protective state for a long time. 2. Because the side slot is a trapezoidal structure that is narrow at the top and wide at the bottom, and the two sides at the bottom protrude symmetrically inward, when a thicker cable or multiple cables are threaded at the same time, the slot structure can easily squeeze and obstruct the cable, and may even cause the cable to be damaged by friction with the edge of the slot.

[0005] In response to the above situation, this utility model proposes an edge protection ring for electrical cable routing. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electrical cable routing edge protection ring to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrical cable routing edge protection ring, including a protective end face, one end of which is provided with a plug-in portion for plugging into the inner wall of one end of a metal cable tray, the inner side of which forms a protective cavity for accommodating the electrical cable to prevent wear caused by friction between the cable and the metal cable tray or other metal parts, and the plug-in portion is provided with a snap-fit ​​component for positioning and fixing the plug-in portion to the inner wall of the end of the metal cable tray.

[0008] Preferably, the plug-in part and the protective end face are an integral structure, together forming the edge protection ring body. The corners of the plug-in part and the protective end face are rounded, and the transition between the plug-in part and the protective end face is also rounded.

[0009] Preferably, the snap-fit ​​assembly includes at least two snap-fit ​​blocks, which are spaced apart on one side of the insertion part along the height direction of the insertion part. The snap-fit ​​blocks and the insertion part are made of the same material and are integrally formed. One side surface of the snap-fit ​​block is set with an inclination, and the snap-fit ​​block is adapted to the inherent slot structure on the metal wire groove.

[0010] Preferably, both the protective end face and the insertion part are made of thermoplastic elastomer material.

[0011] The technical effects and advantages of this utility model are as follows: 1. By inserting the plug into the inner wall of the end of the metal cable tray, the protective cavity on the inner side of the protective end face forms a physical barrier, directly blocking the frictional contact between the electrical cable and the metal cable tray or other metal parts, reducing wear from the source. The corners and transitions of the integrated body are rounded, which can prevent sharp edges from scratching the cable during installation and wiring. At the same time, the thermoplastic elastomer material of the protective end face and the plug has both insulation and wear resistance. Insulation can reduce electrical safety risks, while wear resistance extends the service life of the protective ring itself, achieving multiple protections for the cable and ensuring that the protective ring plays a stable role in the long term. 2. The snap-fit ​​assembly has at least two snap-fit ​​blocks spaced apart along the height of the plug-in part, with one side being beveled. Combined with the thermoplastic elastomer material properties of the protective end face and the plug-in part, the stability during installation is improved, while the elastic material reduces the plug-in resistance, allowing the plug-in part to be smoothly inserted into the wire groove. This not only simplifies the installation steps but also ensures that it will not fall off during long-term use, significantly improving the assembly efficiency and stability of electrical wiring.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As attached Figure 1-4 The electrical cable routing edge protection ring shown includes a protective end face 1. One end of the protective end face 1 is provided with a plug-in part 2 for plugging into the inner wall of one end of the metal cable tray. The inner side of the protective end face 1 forms a protective cavity 3 for accommodating the electrical cable to prevent the cable from rubbing against the metal cable tray or other metal parts and causing wear. The plug-in part 2 is provided with a snap-fit ​​component for positioning and fixing the plug-in part 2 to the inner wall of the end of the metal cable tray.

[0019] Specifically, in this structure, the plug-in part 2 of the protective end face 1 is plugged into the end of the metal wire trough, the protective cavity 3 inside the protective end face 1 is used to accommodate the electrical cable, and the snap-fit ​​component on the plug-in part 2 is used to position and fix itself to the inner wall of the end of the metal wire trough. During the routing of electrical cables, the protective end face 1 and the protective cavity 3 form a physical barrier to prevent the cable from directly contacting the metal cable tray or other metal parts, thereby avoiding wear and tear on the cable due to friction.

[0020] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 1 and 3, the plug-in part 2 and the protective end face 1 are an integral structure, together forming the edge protection ring body. The corners of the plug-in part 2 and the protective end face 1 are rounded, and the transition between the plug-in part 2 and the protective end face 1 is also rounded.

[0021] Specifically, in this structure, the plug-in part 2 and the protective end face 1 are integrated into one structure, forming the main body of the protective ring. The corners and transitions of both are rounded, which not only avoids wear caused by friction between the cable and the metal trough or other metal parts, but also provides additional protection for the cable and operation during installation and wiring through the rounded corner structure.

[0022] In this embodiment, as shown in the appendix Figure 1 , 4 As shown, the snap-fit ​​assembly includes at least two snap-fit ​​blocks 4. The snap-fit ​​blocks 4 are spaced apart on one side of the plug-in portion 2 along the height direction of the plug-in portion 2. The snap-fit ​​blocks 4 and the plug-in portion 2 are made of the same material and are integrally formed. One side surface of the snap-fit ​​block 4 is set as an inclined surface, and the snap-fit ​​block 4 is adapted to the inherent slot structure on the metal wire groove.

[0023] Specifically, the snap-fit ​​assembly of this structure consists of at least two snap-fit ​​blocks 4 spaced apart along the height direction of the insertion part 2 on one side of the insertion part 2. The snap-fit ​​blocks 4 and the insertion part 2 are made of the same material and are integrally molded to ensure structural strength and simplify the processing technology. Meanwhile, one side of the card block 4 is beveled to facilitate insertion operation, and the card block 4 can be precisely adapted to the inherent card slot structure on the metal wire trough. Through the cooperation of the card block 4 and the card slot, the insertion part 2 of the protective ring can be firmly positioned and fixed on the inner wall of the end of the metal wire trough, ensuring that the overall installation of the protective ring is reliable. In turn, relying on the protective end face 1 and the protective cavity 3, the cable and metal parts are continuously blocked from rubbing against each other, thus avoiding cable wear.

[0024] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 3 and 4, both the protective end face 1 and the plug part 2 are made of thermoplastic elastomer material.

[0025] Specifically, both the protective end face 1 and the plug-in part 2 are made of thermoplastic elastomer material. When the edge protection ring body is installed, the characteristics of thermoplastic elastomer material are used to make the plug-in part 2 smoothly plug into the end of the metal wire trough. Moreover, during use, the insulation and wear resistance of thermoplastic elastomer material can better achieve the anti-wear protection of the cable.

[0026] Working principle of this utility model: This application provides an edge protection ring for electrical cable routing. When in use, relying on the characteristics that both its protective end face 1 and the plug part 2 are made of thermoplastic elastomer, the plug part 2 is smoothly inserted into the end of the metal cable tray. During the insertion process, the plug part 2 can be firmly positioned on the inner wall of the metal cable tray by the cooperation of the locking block 4 and the locking slot, thus completing the installation. After installation, the integrated protective ring body, consisting of the plug-in part 2 and the protective end face 1, has rounded corners and transition points to prevent additional damage to the cable during installation and wiring. When the electrical cable is routed, the protective cavity 3 inside the protective end face 1 accommodates the cable. The thermoplastic elastomer material has both insulation and wear resistance. Combined with the physical barrier formed by the protective cavity 3, it can effectively prevent the cable from directly contacting the metal cable tray or other metal parts, thereby preventing the cable from being worn due to friction.

[0027] It is worth noting that the edge protection ring in this application is made by mold, and its specific size can be produced according to the size of the metal wire trough, which will not be described in detail in this application.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
