[0044] Figure 1 Schematic diagram of the structure of the cable connection device of the embodiment of the utility model, as shown in Figure 1 As shown, the cable connection device 100 of the present invention includes a first cable clamp 110, a second cable clamp 120, and a connection assembly 130, wherein the first cable clamp 110 and the second cable clamp 120 respectively clamp cables extending in different directions, and the first cable clamp 110 and the second cable clamp 120 are connected via the connection assembly 130.

[0045] Therefore, the cable connection device of the present invention can achieve spacing between cross-connected cables without any false connection or overlapping. According to the cable connection device 100 provided by the present invention, cables extending in different directions are conductively connected through the connection component 130, making the conductive connection between the cables more reliable. It should be particularly noted that the cables extending in different directions are connected in series without destroying the original structure.

[0046] More specifically, in the cable connection device of the present invention, the first cable clamp 110 is provided with a first clamping portion 111, and the first clamping portion 111 is used to clamp one or more cables. The second cable clamp 120 is provided with a second clamping portion 121, and the second clamping portion 121 is used to clamp cables having a different extension direction from the cables in the first clamping portion 111. By providing the first clamping portion 111 and the second clamping portion 121 for clamping the cables, the reliability of the cable connection is ensured and the possibility of a false connection of the cables is prevented.

[0047] The number of the first clamping parts 111 in the first cable clamping member 110 and the number of the second clamping parts 121 in the second cable clamping member 120 are not limited, and one or more first clamping parts 111 and one or more second clamping parts 121 may be provided according to actual needs.

[0048] In the cable connection device of the present invention, a connection component 130 is also separately provided, through which the connection position between the first cable clamp 110 and the second cable clamp 120 can be adjusted, and the relative position of the first cable clamp 110 and the second cable clamp 120 can be adjusted conveniently. In other words, by adjusting the connection component 130, the cable in the first cable clamp 110 and the cable in the second cable clamp 120 can be extended in any direction.

[0049] Figure 2 Schematic diagram of a structure in which a plurality of cables extending in different directions are arranged in a cable connection device of an embodiment of the utility model, wherein the structures of the first cable clamp 110 and the second cable clamp 120 are different; Figure 2 As shown, two cables are arranged in the first cable clamp 110 , and the two cables extend in different directions respectively. The two cables are arranged in the same first cable clamp 110 , so that the connection between the two cables is more reliable.

[0050] It should be noted that the number of cables in the first cable clamp 110 is not limited, and different cables can be arranged in the same first clamping portion 111 , or multiple first clamping portions 111 can be provided, with one cable arranged in each first clamping portion 111 .

[0051] A cable is arranged in the second cable clamp 120, and the extension direction of the cable is perpendicular to the extension direction of the two cables in the first cable clamp 110, that is, the extension directions of the cables in the first cable clamp 110 and the second cable clamp 120 are different. Such an arrangement enables the cables extending in different directions to be arranged at intervals, and no virtual connection or overlapping occurs within a limited space.

[0052] In the cable connection device 100 of the present embodiment, a bent conductor is used to connect the first cable clamp 110 and the second cable clamp 120, wherein the bending angle of the conductor can be any angle, such as 90°, and can also be set to different angles such as 60°, 30°, 120°, 150°, etc., and the user can adjust it according to actual needs.

[0053] In the cable connecting device of this embodiment, the first cable clamp 110 and the second cable clamp 120 have different structural features. The specific structures of the first cable clamp 110 and the second cable clamp 120 for clamping the cable are described in detail in the following specific embodiments and drawings.

[0054] Figure 3 Schematic diagram of the structure of two cables arranged at intervals in the cable connection device of an embodiment of the utility model, wherein the first cable clamping member 110 and the second cable clamping member 120 have the same structure; Figure 3 As shown, the first cable clamp 110 and the second cable clamp 120 in the cable connection device 100 in this embodiment have the same structure and clamp the cables extending in different directions respectively, so that the cables extending in different directions are arranged at intervals, thereby reducing the possibility of short circuit. Figure 3 As shown, cables extending in different directions can be connected in the first clamping portion 111 or the second clamping portion 121 by crimping, cables extending in different directions can be connected in the first clamping portion 111 or the second clamping portion 121 by snapping, and cables extending in different directions can also be connected in the first clamping portion 111 or the second clamping portion 121 by welding.

[0055] in, Figure 2 and Figure 3 The cables are only shown in the first clamping portion 111 of the first cable clamp 110 and in the second clamping portion 121 of the second cable clamp 120 , and are not fixedly connected to the first cable clamp 110 or the second cable clamp 120 .

[0056] from Figure 2 and Figure 3 It can be clearly seen that the cable connection device 100 of the present invention can realize that cables in different directions can be spaced and reliably connected together in a limited space without short circuit, thereby reducing safety hazards and reducing the occurrence of fire accidents.

[0057] It should also be noted that the cable connection device of the present invention can also realize series connection between cables in different directions without destroying the original structure of the cables, thereby reducing the phenomenon of cable disconnection in complex circuits and ensuring that the cables have better integrity as much as possible.

[0058] Figure 4 FIG. 1 is a schematic diagram of a first structure of a cable clamping member of a cable connection device of the present utility model, as shown in FIG. Figure 4 As shown, the cable clamp is provided with a through hole for passing the cable, wherein the cable passed through the through hole can be connected to the cable clamp by crimping or welding.

[0059] There is no limit to the number of penetration holes, and multiple penetration holes can be arranged at intervals according to actual needs; the penetration holes can also be appropriately enlarged to be suitable for passing multiple cables; the above two implementation methods can both realize the arrangement of multiple cables in the same cable clamp, thereby increasing the scope of application of the cable clamp.

[0060] When the cable clamp in this embodiment is used as the first cable clamp 110 in the cable connection device 100 , one or more first through holes 114 may be provided on the first cable clamp 110 .

[0061] Similarly, when the cable clamp in this embodiment is used as the second cable clamp 120 in the cable connection device 100 , one or more second through holes 124 may be provided on the first cable clamp 110 .

[0062] In particular, near the through hole of the cable clamp in this embodiment, a first recess 115 or a second recess 125 for fixedly connecting with the connecting component 130 is further provided, wherein the first recess 115 or the second recess 125 is used to accommodate the connecting component 130 with a columnar structure, and is fixedly connected with the columnar structure of the connecting component 130 by welding or crimping.

[0063] Thus, the first cable clamp 110 and the second cable clamp 120 are respectively reliably and stably connected to the connecting assembly 130 , and the cables extending in different directions arranged in the first cable clamp 110 and the second cable clamp 120 are also connected in an electrically conductive manner.

[0064] Figure 5 Schematic diagram of the second structure of the cable clamp of the cable connection device of the utility model; Figure 5 As shown, the cable clamp provided by the cable connection device 100 in this embodiment has a portion of its outer surface recessed inward to form a first clamping portion 111 , and the cable clamp can be used as the first cable clamp 110 of the cable connection device 100 of the present invention.

[0065] It can also be used as the second cable clamp 120 . When used as the second cable clamp 120 , part of its outer surface is recessed inward to form a second clamping portion 121 .

[0066] Figure 6 FIG. 1 is a third structural schematic diagram of the cable clamping member of the cable connecting device of the present utility model, as shown in FIG. Figure 6 As shown, the cable clamp in this embodiment can be used as the first cable clamp 110 and the second cable clamp 120 of the cable connection device 100 of the utility model. When used as the first cable clamp 110, part of its outer surface is recessed inward to form a first clamping portion 111 for clamping and fixing the cable; when used as the second cable clamp 120, part of its outer surface is recessed inward to form a second clamping portion 121 for clamping and fixing the cable.

[0067] Combination Figure 2 and Figure 3 A first groove 112 is formed by partially recessing the outer surface of the first cable clamp 110 inwardly, and the first groove 112 serves as the first clamping portion 111 of the first cable clamp 110 . A second groove 122 is formed by partially recessing the outer surface of the second cable clamp 120 inwardly, and the second groove 122 serves as the second clamping portion 121 of the second cable clamp 120 .

[0068] Among them, the extension direction of the first groove 112 and the extension direction of the second groove 122 are consistent with the extension direction of the cable they clamp. Such an arrangement allows the first clamping portion 111 and the second clamping portion 121 to surround the entire outer circumference of the cable or part of the outer circumference of the cable along the extension direction of the cable, thereby increasing the contact area with the cable and making its connection more reliable.

[0069] like Figure 2 and Figure 3 As shown, the inner surface of the first groove 112 and the inner surface of the second groove 122 are both arc-shaped, and the first groove 112 and the second groove 122 are both suitable for accommodating the cable, and the cable is inserted into the first groove 112 or the second groove 122; the arc-shaped inner surfaces of the first groove 112 and the second groove 122 can better contact the outer surface of the cable.

[0070] like Figure 2 and Figure 3 As shown, the first groove 112 has a first opening 113. In a plane perpendicular to the extension direction of the cable, the wall thickness of the first groove 112 gradually increases from the first opening 113 to the middle area of ​​the arc where the first groove 112 is located;

[0071] The second groove 122 has a second opening 123 . In a plane perpendicular to the extension direction of the cable, the wall thickness of the second groove 122 gradually increases from the second opening 123 to the middle area of ​​the arc where the second groove 122 is located.

[0072] In this embodiment, the cable can be extended into the first groove 112 of the first cable clamp 110 through the first opening 113, and then the first cable clamp 110 and the cable are crimped to be fixedly connected; similarly, the cable can be extended into the second groove 122 of the second cable clamp 120 through the second opening 123, and then the second cable clamp 120 and the cable are crimped to be fixedly connected to the second cable clamp 120.

[0073] In this embodiment, the first groove 112 of the first cable clamp 110 extends inward at the first opening 113 and its wall thickness gradually increases. The second groove 122 of the second cable clamp 120 extends inward at the second opening 123 and its wall thickness gradually increases, which is conducive to molding by crimping.

[0074] Figure 7 Schematic diagram of the structure of the connecting assembly of the cable connecting device of the present invention, such as Figure 7 As shown, the connection assembly 130 includes at least one conductive member 131, which is provided with a first end 1311 and a second end 1312, and the first end 1311 and the second end 1312 are respectively oriented in different directions; the first end 1311 is connected to the first clamping portion 111, and the second end 1312 is connected to the second clamping portion 121. In the connection assembly 130 of this embodiment, the first clamping portion 111 of the first cable clamping member 110 and the second clamping portion 121 of the second cable clamping member 120 are conductively connected by providing the conductive member 131, so that the cable in the first clamping portion 111 and the cable in the second clamping portion 121 can be connected in series.

[0075] In one embodiment of the utility model, the first end 1311 and the second end 1312 of the conductive member 131 are both columnar structures, which can be set to specific structures such as cylindrical, conical column, etc. At the same time, a first recess 115 is provided in the first cable clamp 110 for connecting with the first end 1311 of the conductive member 131, and a second recess 125 is provided in the second cable clamp 120 for connecting with the second end 1312 of the conductive member 131.

[0076] The cable connecting device 100 in this embodiment provides a specific structure of the connection between the conductive member 131 and the first cable clamping member 110 and the second cable clamping member 120 .

[0077] Specifically, the first end 1311 of the conductive member 131 may be connected to the first recess 115 of the first cable clamp 110 by welding, or the first end 1311 of the conductive member 131 may be connected to the first recess 115 of the first cable clamp 110 by crimping;

[0078] The second end 1312 of the conductive member 131 may be connected to the second recess 125 of the first cable clamp 110 by welding, or may be connected to the second recess 125 of the second cable clamp 120 by crimping.

[0080] The connection structure between the first conductive member 132131 and the first cable clamp 110, and the connection structure between the second conductive member 133131 and the second cable clamp 120 are the same as the connection structure between the conductive member 131 and the first cable clamp 110 and the second cable clamp 120 in the above embodiment, and are not described again.

[0081] In this embodiment, a connecting device connecting the first conductive member 132131 and the second conductive member 133131 may be separately provided so that the angle between the first conductive member 132131 and the second conductive member 133131 can be adjusted. For example, the first conductive member 132131 and the second conductive member 133131 may be connected by a fastener.

[0082] In an embodiment of the present invention, the first cable clamp 110 , the second cable clamp 120 , and the connecting assembly 130 may all be made of a copper-based material, or may be made of an aluminum-based material.

[0083] The cable connecting device 100 in this embodiment is connected using a copper-based material or an aluminum-based material, which is conducive to crimping between the first cable clamp 110 and the cable, and between the second cable clamp 120 and the cable. The use of a material that can be plastically deformed can make the connection between the cable connecting device 100 and the cable tighter and more reliable.
