[0035] Elastic portion 112 Elastic portion 112 Elastic portion 112 In this embodiment, a clamping groove 111 is formed on the conductive connector 11, and a first cable slot 113 and a second cable slot 114 are formed at both ends of the clamping groove 111 to respectively plug the ends of the two cables 2, so that the two cables 2 can be electrically connected through the conductive connector 11; the elastic portion 112 is provided on the conductive connector 11, and the elastic portion 112 extends into the first cable slot 113, and cooperates with the inner wall of the first cable slot 113 of the elastic portion 112 to clamp the cable 2; when the cable 2 is disassembled, the elastic portion 112 can be bent to keep it away from the inner wall of the first cable slot 113, so that the cable 2 can be plugged into the elastic portion 112. The conductive connector 11 can be movably provided with a limiting member 12, the limiting member 12 can be moved toward the inner wall of the first cable slot 113 to press the cable 2 against the inner wall of the first cable slot 113, or the limiting member 12 can be moved away from the inner wall of the first cable slot 113 to facilitate the extension of the cable 2 into the first cable slot 113 or the withdrawal of the cable 2 from the first cable slot 113, and the conductive connector 11 can be movably provided with a limiting member 12, the limiting member 12 can be moved toward the inner wall of the first cable slot 113 to press the cable 2 against the inner wall of the first cable slot 113, or the limiting member 12 can be moved away from the inner wall of the first cable slot 113 to facilitate the extension of the cable 2 into the first cable slot 113 or the withdrawal of the cable 2 from the first cable slot 113, and the conductive connector 11 can be movably provided with a limiting member 12, the limiting member 12 can be moved toward the inner wall of the first cable slot 113 to press the cable 2 against the inner wall of the first cable slot 113, and the conductive connector 11 can be movably provided with a limiting member 12

[0036] It is easy to understand that the elastic portion 112 can also extend into the second cable slot 114 to cooperate with clamping the cable 2 inserted in the second cable slot 114. The specific structure and technical effect are similar to those of the above embodiment and will not be repeated here.

[0037] Similarly, the stopper 12 can also be used to cooperate to fix or release the cable 2 inserted in the second cable slot 114. The specific structure and technical effect are similar to those of the above embodiment, and will not be repeated here.

[0038] The cable connection device 1 of the utility model forms a first cable slot 113 and a second cable slot 114 on a conductive connection member 11, which are respectively plugged with two cables 2 and enable the two cables 2 to be electrically connected; at the same time, an elastic portion 112 is provided on the conductive connection member 11, and the elastic portion 112 cooperates with the inner wall of the first cable slot 113 and / or the second cable slot 114 to clamp and fix the cable 2 when in a free state; when the elastic portion 112 is bent toward the outside of the first cable slot 113 and / or the second cable slot 114, the cable 2 can be conveniently inserted or removed, and is suitable for fixed connection of cables 2 whose wire ends are completely tinned. In addition, by movably setting a limit member 12 on the conductive connecting member 11, the limit member 12 can be close to the inner wall of the first cable slot 113 and / or the second cable slot 114 to compress the cable 2 or away from the inner wall of the first cable slot 113 and / or the second cable slot 114 to loosen the clamping groove 111, which is suitable for the fixed connection of the cable 2 with only the top end of the wire head tinned, so that the cable connection device 1 of the utility model can connect the cables 2 with different tinning methods, which effectively solves the problem in the prior art that when the tinning methods of the wires are different, different types of terminal blocks need to be used according to the tinning methods, which is inconvenient to install and prone to errors.

[0039] In some embodiments, Figures 1 to 4 As shown, the elastic portion 112 cooperates along the width direction of the clamping groove 111 to clamp the cable 2 inserted in the first cable slot 113 and / or the second cable slot 114; the limiting member 12 cooperates along the height direction of the clamping groove 111 to fix or release the cable 2 inserted in the first cable slot 113 and / or the second cable slot 114.

[0040] In this embodiment, the elastic portion 112 can be arranged on the side wall of the clamping groove 111. In the free state, the elastic portion 112 tilts toward the inside of the clamping groove 111, and clamps the cable 2 in the first cable slot 113 and / or the second cable slot 114 along the width direction of the clamping groove 111; the elastic portion 112 is bent toward the outside of the clamping groove 111 to loosen the cable 2, thereby facilitating the removal or insertion of the cable 2; similarly, the limit member 12 can be movable along the height direction of the clamping groove 111, and the limit member 12 is close to the bottom of the clamping groove 111 to press the cable 2 against the bottom of the clamping groove 111, or away from the bottom of the clamping groove 111 to loosen the cable 2, thereby facilitating the removal or insertion of the cable 2. The structure is simple, convenient and practical.

[0041] In some specific embodiments, Figure 2 and Figure 4As shown, there are two elastic parts 112, which are respectively arranged in the first cable slot 113 and the second cable slot 114. The elastic part 112 in the first cable slot 113 is inclined toward the first cable slot 113 along the direction away from the slot of the first cable slot 113; similarly, the elastic part 112 in the second cable slot 114 is inclined toward the second cable slot 114 along the direction away from the slot of the second cable slot 114.

[0042] In this embodiment, the elastic part 112 of the elastic part 112 is tilted toward the inside of the first cable slot 113 by making the elastic part 112 in the first cable slot 113 along the direction away from the slot of the first cable slot 113. When the cable 2 is inserted from the slot of the first cable slot 113, the cable 2 gradually squeezes the elastic part 112 while moving forward along the first cable slot 113, so that the elastic part 112 is deformed and generates elastic force. Under the action of the elastic force, the elastic part 112 automatically abuts and clamps the cable 2, making the installation and connection of the cable 2 simpler and more convenient. Similarly, the structure and technical effects of the elastic part 112 in the second cable slot 114 are similar to those of the elastic part 112 in the first cable slot 113, and are not repeated here.

[0043] In some embodiments, the elastic portion 112 may be Figure 3 and Figure 4 As shown, the cable connection device 1 also includes a shell 13, in which an installation cavity 131 is arranged. A first opening 132 communicating with the outside is opened in the installation cavity 131 at positions corresponding to the notches at both ends of the clamping groove 111, and the conductive connector 11 is arranged in the installation cavity 131.

[0044] In this embodiment, the conductive connector 11 is disposed in the installation cavity 131 of the shell 13, so that the shell 13 can cover the conductive connector 11, thereby preventing the conductive connector 11 and the wire ends of the cable 2 from being exposed to the outside, thereby providing insulation protection for the conductive connector 11 and the cable 2; the cable 2 can be extended into the clamping groove 111 through the first opening 132 for fixation, with a simple structure and strong practicality.

[0045] In some embodiments, Figures 1 to 3 As shown, a first limiting hole 133 communicating with the outside is opened at a position corresponding to the limiting member 12 in the installation cavity 131, and a second limiting hole 115 adapted to the limiting member 12 is opened at a position corresponding to the first limiting hole 133 on the conductive connecting member 11, and the limiting member 12 is movably inserted into the first limiting hole 133 and the second limiting hole 115.

[0046] In this embodiment, by respectively opening a first limiting hole 133 and a second limiting hole 115 on the installation cavity 131 and the conductive connector 11, and movably inserting the limiting member 12 into the first limiting hole 133 and the second limiting hole 115, and being able to move along the first limiting hole 133 and the second limiting hole 115, the limiting member 12 can be close to the bottom of the clamping groove 111, and press the cable 2 against the bottom of the clamping groove 111, so as to clamp and fix the cable 2, and the clamping of the cable 2 is more stable and reliable; when the limiting member 12 is away from the bottom of the clamping groove 111, the cable 2 can be conveniently extended into the clamping groove 111 or pulled out from the clamping groove 111; at the same time, the limiting member 12 can also limit the relative position of the shell 13 and the conductive connector 11, and fix the conductive connector 11 in the installation cavity 131 of the shell 13.

[0047] Specifically, in some embodiments, Figure 1 and Figure 3 As shown, the stopper 12 is a screw, and threads adapted to the screw are configured in the first stopper hole 133 and the second stopper hole 115. In this embodiment, the screw can be screwed into the first stopper hole 133 and the second stopper hole 115 to fix the first stopper hole 133 and the second stopper hole 115 to each other, and the screw can be easily assembled and disassembled.

[0048] In some embodiments, Figure 1 and Figure 3 As shown, the installation cavity 131 is provided with a second opening 134 communicating with the outside at a position corresponding to the elastic portion 112 for moving the elastic portion 112 from the outside so that the elastic portion 112 is deformed and bent toward the outside of the clamping groove 111 to loosen the cable 2.

[0049] In this embodiment, a second opening 134 is provided on the installation cavity 131 to facilitate the installer to use a tool (such as a screwdriver, etc.) from the outside to reach into the installation cavity 131, move the elastic portion 112, and bend the elastic portion 112 away from the inner wall of the clamping groove 111, thereby loosening the cable 2 and facilitating the cable 2 to be pulled out of the clamping groove 111 without removing the shell 13, which is convenient and quick.

[0050] In some embodiments, Figures 2 to 4 As shown, a guide slope 116 is configured on one side of the elastic portion 112 facing the second opening 134 , and the guide slope 116 is inclined toward the outer side of the clamping groove 111 in a direction close to the second opening 134 .

[0051] In this embodiment, a guide slope 116 inclined toward the outside of the first cable slot 113 is constructed on the elastic portion 112. When the installer uses a tool (such as a screwdriver, etc.) from the outside to reach into the installation cavity 131, the guide slope 116 can be abutted, and the elastic portion 112 can be bent toward the outside of the clamping groove 111 through the guide slope 116.

[0052] Elastic part 112 Specifically, in some embodiments, the conductive connector 11 is a copper part, and the elastic part 112 is a copper spring tongue. Copper has good electrical conductivity and can effectively conduct electrical energy. This copper conductive connector 11 plays an important conductive role in electrical equipment. Since the electrical conductivity of copper is known, the use of the copper conductive connector 11 can ensure the effective conduction of electrical energy. In addition, the copper conductive connector 11 also has good corrosion resistance and high strength, which can meet the needs of long-term use.

[0053] In some embodiments, the conductive connector 11 can also be made of other metal materials, such as aluminum, nickel, chromium, etc. These metal materials also have good electrical conductivity and can effectively conduct electrical energy. However, the copper conductive connector 11 has better comprehensive performance in terms of electrical conductivity, corrosion resistance and strength than other metal materials.

[0054] In addition, the design of the elastic portion 112 enables the conductive connector 11 to have a certain elasticity and variability. This design enables the conductive connector 11 to better adapt to different environments and working conditions during assembly and use. The design of the copper spring tongue can provide good elasticity and recovery, thereby ensuring the stability and reliability of the conductive connector 11 during use.

[0055] In summary, the design of the copper conductive connector 11 and the elastic part 112 enables the device to have good conductivity, adaptability and reliability, and can meet the needs of various electrical equipment. At the same time, the use of the device can effectively improve the performance and efficiency of electrical equipment.

[0056] In some embodiments, there are multiple conductive connectors 11, which can connect multiple cables 2 at the same time, and have a simple structure, which is convenient and practical.

[0057] In some embodiments, the conductive connector 11 is not single, but multiple. This design has its unique advantages, making the connection of multiple cables 2 simple and convenient.

[0058] First, the presence of multiple conductive connectors 11 can connect multiple cables 2 at the same time, which greatly improves the connection efficiency. In the traditional connection method, each cable 2 requires a separate connector for connection, which not only takes more time and effort, but also increases the possibility of error. However, this new design only requires one cable connection device 1 to connect multiple cables 2 at the same time, which undoubtedly greatly improves the connection efficiency.

[0059] Secondly, this design is more practical. Since each conductive connector 11 can work independently, even if one of the conductive connectors 11 has a problem, the other conductive connectors 11 can still work normally and will not affect the operation of the entire system. This design also makes maintenance and repair more convenient, because only the conductive connector 11 with a problem needs to be found and repaired, without the need to check all the conductive connectors 11.

[0060] In addition, this design is also simpler in structure. Since the conductive connector 11 works independently, no complex circuit or mechanical structure is required to ensure its normal operation. This simple design makes the entire system more stable and reduces the possibility of failure.

[0061] In general, the design with multiple conductive connectors 11 has higher efficiency, better practicality and simpler structure. This design can not only improve the efficiency of connecting multiple cables 2, but also ensure the stability and reliability of the system. Therefore, this design is worthy of application and promotion in practice.
