Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to an insulated cable and an insulated cable cap. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, and so on.

[0003] Cable end caps are used to seal the ends of cables and prevent water ingress. Existing insulating end caps are mostly heat-shrink caps, which are shrunk and tightly fitted onto the cable end by heating. While this method secures the end cap to the cable, it also damages the cable sheath, causing deformation and potentially subjecting the internal battery cells to excessive stress, which is detrimental to their normal operation. Furthermore, assembling the end cap using this method requires subsequent removal by cutting with a blade, which can easily damage the cable's surface. Therefore, this application proposes an insulated cable and an insulated cable end cap. Utility Model Content

[0004] The purpose of this utility model is to provide an insulated cable and an insulated cable cap, so as to solve the problem that the heated cap will also damage the cable sheath, causing the cable sheath to deform, as mentioned in the background art. At the same time, the cap is assembled by heating, and the cap needs to be removed by cutting with a blade when it is removed. However, the blade cutting can easily scratch the surface of the cable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulated cable, comprising a cable, wherein the cable is provided with an outer sheath, a heat insulation layer for isolating heat transferred from the external environment through the outer sheath, a battery core for transporting electricity and signals, and a frame for fixing the position of the battery core, from the outside to the inside.

[0006] The heat insulation layer is wrapped around the outside of the frame. The frame is provided with a first storage cavity for storing the battery cells and a plurality of second storage cavities. The first storage cavity is located at the center of the frame, and the plurality of second storage cavities are arranged in a circular array around the center line of the first storage cavity.

[0007] Preferably, the outer skin is made of polyethylene material.

[0008] Preferably, the heat insulation layer is made of silicone rubber material, and the thickness of the heat insulation layer is 1.5-3 times the thickness of the outer skin.

[0009] An insulated cable cap includes a cap that covers the end of a cable. The cap includes a housing, a protrusion on the housing, a clamping ring inserted into the protrusion for applying pressure to the cable by the housing, and a rubber ring installed inside the cap to increase the friction between the housing and the cable.

[0010] The housing is provided with several pressure plates, and the inner ring of the pressure plates is interference-fitted with the outer wall of the cable.

[0011] Preferably, three pressure plates are provided, and the three pressure plates are arranged in a circumferential array around the center line of the cap.

[0012] Preferably, the housing has a plurality of recesses for easy gripping, and the plurality of recesses are arranged in a circumferential array around the center line of the housing.

[0013] Preferably, the housing has several grooves inside, and reinforcing steel rings are inserted into the grooves.

[0014] Preferably, there are two reinforcing steel rings, which are located at the top and bottom of the shell, respectively.

[0015] Preferably, the cross-section of the pressure plate is U-shaped, and a friction pad is wrapped around the side of the pressure plate closest to the cable.

[0016] Preferably, the cap has an inner cavity, and the housing has a plurality of vent holes communicating with the inner cavity.

[0017] Beneficial effects:

[0018] I. This utility model provides an insulated cable and an insulated cable cap. The frame is provided with a first storage cavity for storing battery cells and multiple second storage cavities. The multiple second storage cavities are distributed around the first storage cavity. In this way, battery cells are inserted into each second storage cavity and the first storage cavity. The battery cells are evenly distributed and isolated from each other, so that the battery cells do not interfere with each other and work stably. At the same time, an outer sheath and heat insulation layer are provided on the outside of the frame to isolate external heat and prevent external temperature from being directly transferred to the internal battery cells, so as to prevent the battery cells from overheating due to external heat and allow the battery cells to work at a more suitable temperature.

[0019] II. The present invention provides an insulated cable and an insulated cable cap. The inner ring of the pressure plate is interference-fitted with the outer wall of the cable. The friction pad is made of rubber material. The friction coefficient between the friction pad and the cable is relatively large. Compared with the rubber ring, the friction pad has a larger contact area with the cable, providing greater friction at the connection between the cable and the cap. This can prevent the cap from detaching from the cable. When inserting or removing the cap, the pressure plate can be manually pushed to the side away from the cable, which will greatly reduce the friction between the cap and the cable. The insertion and removal of the cap are relatively effortless. Attached Figure Description

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figure 2 , Figure 3 As shown in the figure, an insulated cable provided by this utility model includes a cable 1. The cable 1 is provided with an outer sheath 101, a heat insulation layer 102 for isolating heat transferred from the external environment through the outer sheath 101, a battery core 103 for transporting electricity and signals, and a frame 104 for fixing the position of the battery core 103, arranged sequentially from the outside to the inside. The frame 104 is made of insulating material, and the outer side of the battery core 104 is wrapped with insulating material to prevent leakage of the battery core 104. The insulating material is made of polyvinyl chloride and can be wrapped on the outside of the battery core 104 using a common extruder.

[0028] Specifically, the outer skin 101 is made of polyethylene material and is wrapped around the outside of the insulation layer 102 by an extruder.

[0029] For reference Figure 2The heat insulation layer 102 is made of silicone rubber, and its thickness is 1.5-3 times that of the outer skin 101. The heat insulation layer 102 wraps around the outside of the skeleton 104. The molding principle of the heat insulation layer 102 is roughly the same as that of the outer skin 101, which is also wrapped around the outside of the skeleton 104 by an extruder. However, the thickness of the heat insulation layer 102 is greater than that of the outer skin 101, so it requires a longer cooling time after molding.

[0030] It should be noted that the frame 104 is provided with a first storage cavity and a plurality of second storage cavities for storing the battery cells 103. The first storage cavity is located at the center of the frame 104, and the plurality of second storage cavities are arranged in a circumferential array around the center line of the first storage cavity. The plurality of second storage cavities are distributed around the first storage cavity, so that each second storage cavity and the first storage cavity are inserted with battery cells 103. The battery cells 103 are evenly distributed and isolated from each other, so that the battery cells 103 do not interfere with each other and work stably. At the same time, an outer skin 101 and a heat insulation layer 102 are provided on the outside of the frame 104, which can isolate external heat and prevent external temperature from being directly transferred to the internal battery cells 103, so as to prevent the battery cells 103 from overheating due to external heat and allow the battery cells 103 to work at a more suitable temperature.

[0031] like Figures 1-4 As shown, an insulated cable cap includes a cap 2, which covers the end of a cable 1. The cap 2 includes a housing 201, a protrusion 202 disposed on the housing 201, a clamping ring 203 inserted into the protrusion 202 for applying pressure to the housing 201 to compress the cable 1, and a rubber ring 204 installed inside the cap 2 to increase the friction between the housing 201 and the cable 1.

[0032] The cap 2 is directly fitted onto the end of the cable 1. The inner shell 201, protrusion 202, and clamping ring 203 of the cap 2 can compress the inner cable 1, making it difficult for the cable 1 to fall off the cap 2. At the same time, a rubber ring 204 is set between the clamping ring 203 and the cable 1. The rubber ring 204 is pressed against the cable 1 by the clamping ring 203. The friction coefficient between the rubber ring 204 and the cable 1 is relatively large, which can prevent the cap 2 from separating from the cable 1.

[0033] To further increase the friction between the cap 2 and the cable 1 and prevent the cap 2 from falling off, several pressure plates 207 are provided at the housing 201. The cross-section of the pressure plate 207 is U-shaped. A friction pad 208 is wrapped around the side of the pressure plate 207 near the cable 1. The inner ring of the pressure plate 207 is interference-fitted with the outer wall of the cable 1. The friction pad 208 is made of rubber. The friction coefficient between the friction pad 208 and the cable 1 is relatively large. Compared with the rubber ring 204, the friction pad 208 has a larger contact area with the cable 1, providing greater friction at the connection between the cable 1 and the cap 2. This can prevent the cap 2 from falling off the cable 1. When inserting or removing the cap 2, the pressure plate 207 can be manually pushed to bend away from the cable 1 (the bending is a recoverable elastic deformation). This will greatly reduce the friction between the cap 2 and the cable 1, and the insertion of the cap 2 will be easier.

[0034] It should be noted that there are three pressure plates 207, and the three pressure plates 207 are arranged in a circular array around the center line of the cap 2.

[0035] To facilitate the gripping and insertion / removal of the cap 2, a number of recesses 205 for easy gripping are provided inside the housing 201, and the multiple recesses 205 are arranged in a circumferential array around the center line of the housing 201.

[0036] In order to improve the strength of the cap 2, several grooves are provided in the housing 201, and reinforcing steel rings 206 are inserted into the grooves. There are two reinforcing steel rings 206, which are located at the top and bottom of the housing 201 respectively.

[0037] It should be noted that the cap 2 has an inner cavity 210, and the housing 201 has several vent holes 209 communicating with the inner cavity 210. The inner cavity 210 is connected to the end of the cable 1 through the vent holes 209, and is used to store the air that is not discharged between the cap 2 and the cable 1 when the cap 2 is inserted into the cable 1. After the inner cavity 210 is inserted into the cable 1, it is isolated from the outside. In this way, even if the air pressure in the inner cavity 210 is higher than that on the outside, it will not generate a thrust sufficient to detach the cap 2 from the cable 1.

[0038] In summary, this utility model embodiment provides an insulated cable and an insulated cable cap. The frame 104 is provided with a first storage cavity for storing battery cells 103 and multiple second storage cavities. The multiple second storage cavities are distributed around the first storage cavity, so that battery cells 103 are inserted into each second storage cavity and the first storage cavity. The battery cells 103 are evenly distributed and isolated from each other, which allows the battery cells 103 to work stably without interference. At the same time, an outer sheath 101 and a heat insulation layer 102 are provided on the outside of the frame 104 to isolate external heat and prevent external temperature from being directly transferred to the internal battery cells 103, thus preventing the battery cells 103 from overheating due to external heat and allowing the battery cells 103 to work at a more suitable temperature.

[0039] The inner ring of the pressure plate 207 is interference-fitted with the outer wall of the cable 1. The friction pad 208 is made of rubber. The friction coefficient between the friction pad 208 and the cable 1 is relatively large. Compared with the rubber ring 204, the friction pad 208 has a larger contact area with the cable 1, which provides greater friction at the connection between the cable 1 and the cap 2. This can prevent the cap 2 from detaching from the cable 1. When inserting or removing the cap 2, the pressure plate 207 can be manually pushed to bend away from the cable 1. This will greatly reduce the friction between the cap 2 and the cable 1, and the insertion of the cap 2 will be easier.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
