Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technology, specifically relating to a cable splitter and a cable assembly. Background Technology
[0002] Cables are one of the main tools for power transmission. During cable laying, there are usually many cable branches. Besides pulling additional branch cables from the end of the main cable, it is sometimes necessary to connect branch cables at a certain point within the main cable itself. Therefore, cable splitters are needed for branching operations, that is, to connect the main cable and branch cables. Cable splitters typically include split-type splitters, plug-in type splitters, and crimp type splitters.
[0003] For split-type splitters, it is usually necessary to strip the protective sheath of the main cable and place the exposed main cable core into the U-shaped groove of the split-type splitter, and place the end of the branch cable into the branch hole of the split-type splitter. Screws are then used to tighten the core and the split-type splitter, as well as the branch cable and the split-type splitter. However, this wiring process is cumbersome. For plug-in type splitters, a probe or pin is typically inserted vertically into the protective sheath of the main cable so that one end of the probe or pin contacts the core, and the other end contacts the branch cable. However, because the contact area between the probe or pin and the core is usually small, this can easily lead to excessive contact resistance. Therefore, plug-in type splitters are only suitable for applications where small-power loads are connected to the branch cable. For crimp-type splitters, the main cable is usually divided into two parts, with one part of the main cable connected to the branch cable and the other part of the main cable via the crimp-type splitter. However, disconnecting the main cable increases the resistance of the main cable itself.
[0004] In summary, the cable splitters involved in the relevant technologies have problems such as complicated wiring, inflexibility in adapting to loads of different power, and easy increase in the overall cable resistance during application. Utility Model Content
[0005] This application discloses a cable splitter and a cable assembly to solve the problems of cumbersome wiring, inflexibility in adapting to loads of different power, and easy increase in the overall cable resistance of cable splitters in the application process.
[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution: A cable splitter for connecting a main cable and branch cables, the cable splitter including conductive tabs and connectors. The conductive insert is electrically connected to the connector. The conductive insert is arc-shaped, and at least a portion of the conductive insert is used to pass through the protective sheath of the main cable and enter the gap between the protective sheath and the battery core of the main cable along the extension direction of the main cable to fit against the battery core. The connector is used to electrically connect to the branch cable.
[0007] A cable assembly includes a main cable, branch cables, and the cable splitter described above, wherein the main cable is electrically connected to the branch cables via the conductive insert and the connector.
[0008] The technical solution adopted in this application can achieve the following beneficial effects: In this application, because the conductive insert is arc-shaped, and only requires at least a portion of the conductive insert to enter the gap between the protective sleeve and the battery core of the main cable along the extension direction of the main cable to fit against the battery core, the purpose of electrically connecting the main cable and branch cables through the conductive insert and connector can be achieved. This electrical connection process is relatively simple. Furthermore, because the conductive insert is arc-shaped, the contact area between the conductive insert and the arc-shaped battery core is relatively large, resulting in relatively low contact resistance and thus relatively high conductivity. Therefore, this application allows for flexible connection of loads of different power on the branch cable, and since this application does not require disconnecting the main cable, it does not increase the resistance of the main cable itself. Therefore, the cable splitter disclosed in this application can solve the problems of cumbersome wiring, inflexible application to loads of different power, and easy increase in the resistance of the main cable in the application of related technologies.

Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0012] The cable splitter disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0013] Please refer to Figures 1-5 This application discloses a cable splitter, which includes conductive inserts 200 and connectors 300.
[0014] The cable splitter disclosed in this application is used to electrically connect the main cable 100 and branch cables, specifically through conductive inserts 200 and connectors 300. The conductive inserts 200 are electrically connected to the connectors 300. The conductive inserts 200 are arc-shaped, and at least a portion of the conductive inserts 200 is used to pass through the protective sleeve 110 of the main cable 100 and enter the gap between the protective sleeve 110 and the battery core 120 of the main cable 100 along the extension direction of the main cable 100, so as to fit against the battery core 120. That is, the protective sleeve 110 can cover at least a portion of the conductive inserts 200.
[0015] Because the conductive insert 200 is arc-shaped (i.e., it has an arc-shaped surface), while the battery cell 120 is typically cylindrical (i.e., its side surface is arc-shaped), the shapes of the conductive insert 200 and the battery cell 120 are well-matched. This results in a larger contact area, reducing the resistance between them and ensuring conductivity between the conductive insert 200 and the battery cell 120. Simultaneously, the connector 300, being a conductive element, is used for electrical connection with the branch cable. This allows for the electrical connection of the main cable 100 and the branch cable via the conductive insert 200 and the connector 300. Furthermore, the on-resistance of the cable splitter disclosed in this application can be less than or equal to 0.02Ω.
[0016] In this application, since the conductive insert 200 is arc-shaped, and since this application only requires at least a portion of the conductive insert 200 to enter the gap between the protective sleeve 110 and the battery core 120 of the main cable 100 along the extension direction of the main cable 100, so as to fit with the battery core 120, the purpose of electrically connecting the main cable 100 and the branch cable through the conductive insert 200 and the connector 300 can be achieved. This electrical connection process is relatively simple. At the same time, since the conductive insert 200 is arc-shaped, the contact area between the conductive insert 200 and the battery core 120 with arc-shaped sides is relatively large, thereby making the contact resistance between the two relatively small and the conductivity relatively high. Therefore, this application can flexibly connect loads of different power on the branch cable, and since this application does not require disconnecting the main cable 100, the resistance of the main cable 100 itself will not be increased. Therefore, the cable splitter disclosed in this application can solve the problems of cumbersome wiring, inability to flexibly adapt to loads of different power, and easy increase of the total cable resistance in the application of cable splitters involved in related technologies.
[0017] Optionally, the connector 300 can be located at one end of the conductive insert 200, and the connector 300 can be used to plug into a branch cable to achieve electrical connection with the branch cable. This connection method is simple and quick, and can further solve the problem of cumbersome wiring. Optionally, the plug hole on the connector 300 can be adapted to various branch cables with different cross-sectional areas, such as different branch cables with cross-sectional areas of 2.5mm², 4mm², and 6mm². Of course, the embodiments of this application do not impose specific limitations on this.
[0018] Optionally, the conductive insert 200 can be made of copper, which has good conductivity. A tin layer can be plated on the outer surface of the conductive insert 200. That is, a tin layer can be plated on the first arc-shaped surface of the conductive insert 200 that is in contact with the battery cell 120 and on the second arc-shaped surface that is opposite to the first arc-shaped surface, in order to prevent the copper from oxidizing. Tin also has good conductivity, which can better ensure the conductivity of the conductive insert 200.
[0019] Alternatively, please refer to Figure 1 and Figure 2 The conductive insert 200 has a first end 210 and a second end 220 arranged opposite to each other in its axial direction. The first end 210 is electrically connected to the connector 300, and the second end 220 is used to pass through the protective sleeve 110. The second end 220 may be provided with a deformation notch 230 so that the arc length of the conductive insert 200 can be changed, thereby flexibly fitting battery cells 120 of different diameters. That is, this application can be applied to the operation of branching a total cable 100 of different diameters. Of course, in other embodiments, the second end 220 may not be provided with a deformation notch 230.
[0020] Optionally, the deformation notch 230 extends along the axial direction of the conductive insert 200, and the opening size of the deformation notch 230 can gradually decrease in the direction extending from the second end 220 to the first end 210. This allows the arc length of the conductive insert 200 to vary, thus flexibly adapting to total cables 100 of different diameters, while avoiding affecting the structural strength of the conductive insert 200. Of course, in other embodiments, the opening size of the deformation notch 230 can remain constant in the direction extending from the second end 220 to the first end 210.
[0021] Optionally, in the direction extending from the second end 220 to the first end 210, the opening size of the deformation notch 230 can gradually transition from 5mm to 1mm, that is, the opening size of the deformation notch 230 can be between 1mm and 5mm, which allows the conductive insert 200 to fit the total cable 100 with a cross-sectional area between 2.5mm² and 6mm². Of course, the embodiments of this application do not impose specific limitations on this.
[0022] Optionally, as described above, the conductive insert 200 has a first end 210 and a second end 220 arranged opposite to each other in its axial direction. The first end 210 is electrically connected to the connector 300, and the second end 220 may be provided with a blade 221. The shape of the blade 221 is adapted to the shape of the second end 220, that is, the shape of the blade 221 is arc-shaped. The blade 221 is used to pierce the protective sleeve 110. This arrangement allows the conductive insert 200 to directly pierce the protective sleeve 110 and enter the gap between the protective sleeve 110 and the battery cell 120 without the need for other auxiliary tools to open the protective sleeve 110. This makes the process of electrically connecting the main cable 100 and the branch cables through the cable splitter simpler and faster. Of course, in other embodiments, the second end 220 may not be provided with a blade 221.
[0023] Optionally, in the direction extending from the second end 220 to the first end 210, the cross-sectional area of the blade 221 can remain constant or gradually decrease, and in the direction extending from the center of the blade 221 to the edge of the blade 221, the cutting edge angle of the blade 221 can remain constant or gradually decrease.
[0024] In another embodiment, in the direction extending from the second end 220 to the first end 210, the cross-sectional area of the blade 221 can gradually increase, so that the shape of the blade 221 is an arc-shaped cone, and the arc length of the region of the blade 221 away from the second end 220 is smaller, while the arc length of the region near the second end 220 is larger, that is, the blade 221 has a tip, and in the direction extending from the center of the blade 221 to the edge of the blade 221, the cutting edge angle of the blade 221 can gradually increase, so that the blade 221 is thinner in the middle and thicker at the edge, thereby making the middle position of the blade 221 the sharpest, and gradually blunting towards the edge of the blade 221, that is, the blade 221... The tip of the blade 221 is located in the middle, which allows the user to pierce the protective sleeve 110 with a relatively small force applied to the conductive insert 200. This arrangement makes it easier to pierce the protective sleeve 110. Furthermore, since the cutting edge angle of the blade 221 gradually increases from its center to its edge, the pressure exerted by the protective sleeve 110 on the edge of the blade 221 during insertion of the conductive insert 200 into the main cable 100 is increased. This increases the pressure on the conductive insert 200, ensuring that the conductive insert 200 remains in close contact with the moving battery cell 120. Optionally, the thickness of the blade 221 in the middle can be 0.2 mm, and the thickness of the blade 221 at its edge can be 1.5 mm. Of course, this embodiment does not impose specific limitations on these aspects.
[0025] In this embodiment, the blade 221 of the conductive insert 200 pierces the protective sleeve 110, and as the conductive insert 200 moves along the extension direction of the main cable 100, the two ends of the conductive insert 200 in its circumferential direction are squeezed by the protective sleeve 110 to form a clamping force, so that the conductive insert 200 can move along the battery cell 120.
[0026] As described above, the conductive insert 200 has a first end 210 and a second end 220 arranged opposite to each other in its axial direction. The first end 210 is electrically connected to the connector 300, and the second end 220 is used to pass through the protective sleeve 110. Optionally, the thickness of the conductive insert 200 can gradually increase in the direction extending from the second end 220 to the first end 210, so that as the conductive insert 200 enters the gap between the protective sleeve 110 and the battery cell 120, the protective sleeve 110 is gradually stretched to a greater extent, and the compressive force exerted by the protective sleeve 110 on the conductive insert 200 gradually increases, so that the conductive insert 200 and the battery cell 120 fit better, thereby ensuring conductivity. Of course, in other embodiments, the thickness of the conductive insert 200 can be uniform throughout.
[0027] Optionally, when the insulating sleeve 400 described below is sleeved on the outside of the main cable 100, the second end 220 of the conductive insert 200 will first enter the space between the protective sleeve 110 and the insulating sleeve 400. Since the thickness of the conductive insert 200 gradually increases in the direction of extension from the second end 220 to the first end 210, the squeezing force applied by the insulating sleeve 400 to the conductive insert 200 gradually increases as the conductive insert 200 gradually enters the space between the protective sleeve 110 and the insulating sleeve 400. This makes it more advantageous for the conductive insert 200 to cut into the main cable 100 at a certain angle relative to the extension direction of the main cable 100, thereby piercing the protective sleeve 110.
[0028] Optionally, both the first end 210 and the connector 300 may be provided with an insulating protective layer, and the connection between the first end 210 and the connector 300 may also be provided with an insulating protective layer to prevent users from accidentally touching the exposed first end 210 and connector 300. That is, the portion of the conductive insert 200 located outside the protective sleeve 110 and the connector 300 are both insulated and protected. Of course, in other embodiments, neither the first end 210 nor the connector 300 may be provided with an insulating protective layer.
[0029] In addition, the insulating protective layer can increase the thickness of the first end 210 to a certain extent, so that the extrusion force applied by the protective sleeve 110 to the conductive insert 200 in the reverse direction can be further increased, thereby improving the bonding effect between the conductive insert 200 and the battery cell 120.
[0030] Alternatively, please refer to Figures 3 to 5 The cable splitter may further include an insulating sleeve 400, which is fitted over the main cable 100. The insulating sleeve 400 has a through hole 440, and a portion of the main cable 100 may be located within the through hole 440. A portion of the conductive insert 200 may pass through the space between the insulating sleeve 400 and the main cable 100 and pass through the protective sleeve 110. This allows both the insulating sleeve 400 and the protective sleeve 110 to compress the conductive insert 200 radially from the insulating sleeve 400. In other words, the insulating sleeve 400 can protect the punctured protective sleeve 110. Simultaneously, because both the insulating sleeve 400 and the protective sleeve 110 can compress the conductive insert 200 radially from the insulating sleeve 400, the contact effect between the conductive insert 200 and the battery core 120 is better. Of course, in other embodiments, the cable splitter may not include the insulating sleeve 400.
[0031] Optionally, the end of the through hole 440 may be provided with a chamfer 450 so that the chamfer 450 can play a certain guiding role in the process of the conductive insert 200 entering the space between the protective sleeve 110 and the insulating sleeve 400.
[0032] Optionally, the insulating sleeve 400 may be made of polyvinyl chloride and glass fiber, with the glass fiber accounting for 30%, which gives the insulating sleeve 400 higher elasticity, higher strength and higher insulation properties.
[0033] Optionally, to ensure that the conductive insert 200 and the connector 300 can always stably connect the main cable 100 and the branch cable, one of the conductive insert 200 and the insulating sleeve 400 may be provided with a limiting protrusion 240, and the other may be provided with a limiting groove 410. When a portion of the conductive insert 200 is in contact with the battery cell 120, the limiting protrusion 240 and the limiting groove 410 are engaged in an axial positioning fit of the insulating sleeve 400, that is, an engagement in an axial positioning fit of the main cable 100, to prevent the conductive insert 200 from accidentally detaching from the main cable 100. In other words, the limiting fit of the limiting groove 410 and the limiting protrusion 240 can play a role in preventing loosening. Of course, in other embodiments, one of the conductive insert 200 and the insulating sleeve 400 may not be provided with a limiting protrusion 240, and the other may not be provided with a limiting groove 410.
[0034] Alternatively, please refer to Figure 3 To facilitate the installation of the insulating sleeve 400 over the main cable 100, the insulating sleeve 400 has an axially extending installation opening 420 that connects to the aforementioned through hole 440. The installation opening 420 allows the main cable 100 to be fitted inside the insulating sleeve 400, meaning a portion of the main cable 100 can enter the through hole 440 through the installation opening 420, thus achieving the purpose of fitting the cable inside the insulating sleeve 400. To prevent the main cable 100 from easily detaching from the insulating sleeve 400, a rope can be tied around the outside of the insulating sleeve 400 to prevent the installation opening 420 from being opened.
[0035] In another embodiment, the two ends of the mounting opening 420 in the circumferential direction of the insulating sleeve 400 are a first locking end 421 and a second locking end 422, respectively. Both the first locking end 421 and the second locking end 422 may be provided with toothed portions 423 extending along the axial direction of the insulating sleeve 400. The toothed portions 423 of the first locking end 421 and the second locking end 422 engage with each other to limit the engagement of the first locking end 421 and the second locking end 422 in the circumferential direction of the insulating sleeve 400. That is, in this embodiment, the structure of the insulating sleeve 400 itself can prevent the mounting opening 420 from being accidentally opened, thereby preventing the main cable 100 from easily detaching from the insulating sleeve 400. This can simplify the overall structural complexity of the cable assembly to a certain extent.
[0036] Optionally, the insulating sleeve 400 has a first surface 430 facing the main cable 100. This first surface 430 is specifically the sidewall of the aforementioned through-hole 440. A temperature-sensing coating may be provided on the first surface 430. This coating can monitor the temperature of the contact area between the conductive insert 200 and the battery cell 120, thereby preventing irreversible damage due to excessively high temperatures in this area. Of course, in other embodiments, the first surface 430 may not have a temperature-sensing coating.
[0037] Optionally, the number of conductive inserts 200 and the number of connectors 300 can both be one.
[0038] In another embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The number of conductive inserts 200 and connectors 300 can both be at least two. Each conductive insert 200 corresponds to each connector 300 and is electrically connected. Each conductive insert 200 can be used to enter the gap between the protective sleeve 110 and the battery core 120 in the opposite direction to fit against the battery core 120. This arrangement allows more branch cables to be electrically connected to the same main cable 100. At the same time, since each conductive insert 200 can enter the gap between the protective sleeve 110 and the battery core 120 in the opposite direction, each conductive insert 200 can apply force to the main cable 100 in the opposite direction to prevent the main cable 100 from shifting, thereby ensuring that the main cable 100 always remains stationary and thus avoiding affecting the electrical connection effect of the main cable 100 with other loads.
[0039] The movement process of each conductive tab 200 is as follows, please refer to the following: Figure 4 and Figure 5 Each conductive insert 200 can be simultaneously inserted into the through hole 440 on both opposite sides of the insulating sleeve 400. During the process of entering the space between the insulating sleeve 400 and the protective sleeve 110, each conductive insert 200 can be inclined to cut into the main cable 100, thereby piercing the protective sleeve 110 and adhering to the battery core 120 to continue moving forward until each conductive insert 200 moves into place. At this time, each connector 300 is located outside the insulating sleeve 400 to facilitate electrical connection with different branch cables.
[0040] Optionally, since the conductive insert 200 is electrically connected to the connector 300, and the connector 300 is used for electrical connection with the branch cable, during the process of inserting the conductive insert 200 into the through hole 440, only the conductive insert 200 can be inserted into the through hole 440, while the connector 300 must be outside the insulating sleeve 400 to facilitate electrical connection with the external branch cable. Please refer to... Figure 4 and Figure 5To increase the contact area between the conductive insert 200 and the battery core 120 and improve the overall structural compactness of the cable assembly, the entire conductive insert 200 can be inserted into the through hole 440, allowing for a large-area contact between the conductive insert 200 and the battery core 120. In this case, to avoid the connector 300, the end of the insulating sleeve 400 can be provided with a clearance opening 460. The clearance opening 460 extends axially along the insulating sleeve 400 and connects to the through hole 440. The connection point between the conductive insert 200 and the connector 300 can be located within the clearance opening 460, allowing the insulating sleeve 400 to avoid the connector 300. Of course, in other embodiments, the end of the insulating sleeve 400 may not have the clearance opening 460.
[0041] Alternatively, please refer to Figure 5 This application also discloses a cable assembly including a main cable 100, branch cables and the cable splitter described above, wherein the main cable 100 is electrically connected to the branch cables via conductive inserts 200 and connectors 300.
[0042] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.
[0043] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
