[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cable connection device, which includes a first contact 10, a second contact 20 and a clamping assembly 30, wherein the first end of the first contact 10 is provided with a first cable connection portion, the first end of the second contact 20 is provided with a second cable connection portion, the second end of the second contact 20 is provided with a concave cavity 21, the second end of the first contact 10 can extend into the concave cavity 21 and be electrically connected to the second contact 20, the clamping assembly 30 includes a clamping member 31 and a moving member 32, the clamping member 31 is provided at the first contact The movable member 32 is movably disposed at the second end of the second contact 20 along the radial direction of the second contact 20, and the movable member 32 has an extended state and an evasive state, wherein, when the first contact 10 extends into the concave cavity 21 and the movable member 32 is in the extended state, the movable member 32 is engaged with the snap-fit ​​member 31 to electrically connect the first contact 10 with the second contact 20, and when the movable member 32 is switched from the extended state to the evasive state, the movable member 32 is separated from the snap-fit ​​member 31 to separate the first contact 10 from the second contact 20.

[0034] The cable connection device provided by the present embodiment includes a first contact 10, a second contact 20 and a clamping assembly 30. A first cable connection portion is provided at the first end of the first contact 10, and a second cable connection portion is provided at the first end of the second contact 20. Therefore, the first contact 10 can be connected to the cable under the action of the first cable connection portion, and the second contact 20 can be connected to the cable under the action of the second cable connection portion. A concave cavity 21 is provided at the second end of the second contact 20. The second end of the first contact 10 can extend into the concave cavity 21, so that the first contact 10 and the second contact 20 can be electrically connected. In this way, it can be ensured that two adjacent cables are electrically connected through the first contact 10 and the second contact 20. Among them, in order to ensure that the first contact 10 and the second contact 20 are firmly connected, the clamping member 31 in the clamping assembly 30 is arranged at the second end of the first contact 10, and the moving member 32 is movably arranged at the second end of the second contact 20 along the radial direction of the second contact 20. The moving member 32 switches between the extended state and the avoidance state, thereby realizing the installation and disassembly of the first contact 10 and the second contact 20. Specifically, when the first contact 10 extends into the recessed cavity 21, the movable member 32 is in an extended state, and the movable member 32 can be connected to the snap-in connection with the snap-in connection 31, so that the first contact 10 and the second contact 20 can be firmly connected, thereby realizing electrical connection. When the movable member 32 switches from the extended state to the avoidance state, the movable member 32 and the snap-in connection 31 are separated, thereby facilitating the separation of the first contact 10 and the second contact 20, ensuring the snap-in connection between the control snap-in connection 31 and the movable member 32, and controlling the movable member 32 to separate from the snap-in connection 31, thereby facilitating the connection and disassembly of the first contact 10 and the second contact 20, ensuring a firm connection, and facilitating disassembly. This can solve the problem in the prior art of electrically connecting two cables by moving the cable connector, which makes the connection method complicated and affects the installation efficiency, and the construction personnel may also cause damage to the cable or cable connector during operation, affecting the safe operation of the electrical system, thereby improving the practicality and structural reliability of the cable connection device.

[0035] like Figures 1 to 4As shown, the clamping member 31 includes a connecting column 311 and a locking block 312, the connecting column 311 is extended along the axial direction of the first contact 10, the first end of the connecting column 311 is connected to the second end of the first contact 10, and the locking block 312 is fixedly set on the second end of the connecting column 311, and the cable connecting device also includes a first elastic member 41, the first end of the first elastic member 41 is connected to the first surface of the locking block 312, and the second end of the first elastic member 41 can abut against the bottom wall of the cavity 21, when the first contact 10 extends into the cavity 21 and the moving member 32 is in an extended state, the moving member 32 is clamped with the second surface of the locking block 312, and the first elastic member 41 is in a compressed state. With the above structure, by setting the connecting column 311 and the locking block 312, the first end of the connecting column 311 is connected to the second end of the first contact 10, the locking block 312 is set on the second end of the connecting column 311, the first end of the first elastic member 41 is connected to the first surface of the locking block 312, and the second end of the first elastic member 41 can abut against the bottom wall of the cavity 21 to compress the first elastic member 41, so that the first contact 10 extends into the cavity 21, and the first contact 10 can be ensured under the action of the first elastic member 41. 10 is in contact with the second contact 20, and the moving member 32 is in an extended state at this time, the moving member 32 is snap-connected with the second surface of the locking block 312, and the first elastic member 41 is in a compressed state, so that the first elastic member 41 can apply an elastic force to the first contact 10 away from the second contact 20, thereby ensuring that the moving member 32 is snap-fitted with the second surface of the locking block 312 under the action of the first elastic member 41, thereby ensuring the stability of the snap-fit ​​structure of the first contact 10 and the second contact 20.

[0036] It should be noted that the first surface of the locking block 312 refers to the surface facing the bottom wall of the cavity 21 of the second contact 20 , and the second surface of the locking block 312 refers to the surface facing the second end of the first contact 10 .

[0037] like Figure 2 , Figure 4 as well as Figures 5 to 9As shown, the clamping member 31 also includes a moving block 313 and a second elastic member 314. The moving block 313 is movably arranged on the connecting column 311 along the axial direction of the connecting column 311 and is located between the first end of the connecting column 311 and the locking block 312. The second elastic member 314 is sleeved on the connecting column 311. The first end of the second elastic member 314 abuts against the first surface of the moving block 313, and the second end of the second elastic member 314 abuts against the second surface of the locking block 312. When the first contact 10 extends into the concave cavity 21 and the moving member 32 is in an extended state, the moving member 32 is located between the moving block 313 and the locking block 312 and is clamped with the locking block 312. When the second end of a contact 10 moves toward the direction close to the second end of the second contact 20, the moving block 313 pushes the moving member 32 to switch from the extended state to the avoidance state. After the moving block 313 moves to between the moving member 32 and the locking block 312, the moving member 32 is reset to the extended state. When the second end of the first contact 10 moves toward the direction away from the second end of the second contact 20, the moving block 313 pushes the moving member 32 to switch from the extended state to the avoidance state. After the moving block 313 and the locking block 312 move to the side of the moving member 32 away from the second contact 20, the first contact 10 is separated from the second contact 20, and the moving member 32 is reset to the extended state. The above structure is adopted, by setting the moving block 313 and the second elastic member 314, the moving block 313 is movably set on the connecting column 311 along the axial direction of the connecting column 311, the second elastic member 314 is sleeved on the connecting column 311, and the first end of the second elastic member 314 abuts against the first surface of the moving block 313, and the second end of the second elastic member 314 abuts against the second surface of the locking block 312, so that when the first contact 10 extends into the recessed cavity 21, the moving member 32 is in an extended state, the moving member 32 is located between the moving block 313 and the locking block 312, and the first elastic member 41 is in a compressed state, so that the moving member 32 is engaged with the locking block 312, and when the second end of the first contact 10 is toward the second contact 10, the moving member 32 is engaged with the locking block 312. When the second end of the first contact 10 moves toward the direction away from the second end of the second contact 20, the moving block 313 can push the moving member 32 to switch from the extended state to the avoidance state, so that the moving block 313 moves to between the moving member 32 and the locking block 312, and the moving member 32 is reset to the extended state. When the second end of the first contact 10 moves toward the direction away from the second end of the second contact 20, the moving block 313 can abut and cooperate with the moving member 32, which can not only make the moving block 313 move toward a position close to the locking block 312, but also push the moving member 32 to switch from the extended state to the avoidance state, so that the moving block 313 and the locking block 312 are fitted together. After the moving block 313 is located between the moving member 32 and the locking block 312, the moving member 32 is reset to the extended state.Afterwards, when the second end of the first contact 10 is controlled to move toward the direction away from the second end of the second contact 20, the moving block 313 can apply an elastic force to the moving block 313 towards the second end away from the second contact 20 under the action of the second elastic member 314, and the first elastic member 41 will also apply an elastic force to the locking block 312 towards the second end away from the second contact 20, so that after the moving block 313 and the locking block 312 move to the side of the moving member 32 away from the second contact 20, the first contact 10 and the second contact 20 can be separated. At this time, the moving member 32 is reset to the extended state, which can ensure that the first contact 10 and the second contact 20 can be disassembled and separated.

[0038] like Figure 3 As shown, the cross-sectional dimensions of the moving block 313 and the locking block 312 are both conical structures. The cross-sectional dimension of the locking block 312 gradually increases in the direction from the first contact 10 toward the second contact 20, and the interface dimension of the moving block 313 gradually decreases in the direction from the first contact 10 toward the second contact 20. The maximum diameter dimension of the moving block 313 is greater than the maximum diameter dimension of the locking block 312. By adopting the above structure, the cross-sectional dimensions of the moving block 313 and the locking block 312 are both conical structures. The cross-sectional dimension of the locking block 312 gradually increases in the direction from the first contact 10 toward the second contact 20, and the interface dimension of the moving block 313 gradually decreases in the direction from the first contact 10 toward the second contact 20. In this way, it can be ensured that when the second end of the first contact 10 moves toward the second end close to the second contact 20, the locking block 312 and the moving member 32 are slidably matched, thereby controlling the moving member 32 to switch from the extended state to the avoidance state, and then to the extended state so that the moving member 32 and the locking block 312 are snap-fitted under the action of the first elastic member 41, and can be pushed and matched with the moving member 32 under the action of the moving block 313. In addition, the maximum diameter of the moving block 313 is larger than the maximum diameter of the locking block 312, so that when the second end of the first contact 10 is facing away from the second end of the second contact 20, the moving member 32 can be prevented from falling between the moving block 313 and the locking block 312 again, thereby ensuring that the first contact 10 and the second contact 20 can be separated.

[0039] like Figure 2 and Figure 3As shown, the locking block 312 is provided with a guide boss 3121, the first end of the first elastic member 41 is sleeved on the guide boss 3121, the bottom wall of the cavity 21 is provided with a positioning groove 211, and the second end of the first elastic member 41 can abut against the positioning groove 211. With the above structure, the locking block 312 is provided with a guide boss 3121, the first end of the first elastic member 41 is sleeved on the guide boss 3121, and the second end of the first elastic member 41 abuts against the positioning groove 211 on the bottom wall of the cavity 21, so that when the second end of the first contact 10 extends into the cavity 21, the first elastic member 41 can cooperate with the locking block 312 under the action of the guide boss 3121 and the positioning groove 211, and the locking block 312 can be snap-fitted with the moving member 32.

[0040] like Figure 2 and Figure 4 As shown, the movable member 32 includes a connecting pin 321 and a block 322. The first end of the connecting pin 321 is movably arranged on the second contact 20 along the radial direction of the second contact 20, and the block 322 is arranged on the second end of the connecting pin 321. When the first contact 10 extends into the concave cavity 21 and the movable member 32 is in an extended state, the block 322 is engaged with the engaging member 31. When the movable member 32 switches from the extended state to the avoidance state, the block 322 is separated from the engaging member 31. With the above structure, a connecting pin 321 and a clamping block 322 are provided on the surface, and the clamping block 322 can be clamped with the clamping piece 31, so that the connecting pin 321 can be movably provided in the radial direction of the second contact 20, so that the clamping block 322 can be driven to move, so that when the first contact 10 extends into the recessed cavity 21 of the second contact 20, the clamping block 322 can be ensured to be clamped and matched with the clamping piece 31, and the clamping block 322 can be separated from the clamping piece 31, so that the first contact 10 and the second contact 20 can be easily disassembled.

[0041] like Figure 4 As shown, the moving member 32 also includes a third elastic member 323, the second end of the second contact 20 is provided with a limiting boss 22, the first end of the connecting pin 321 is provided with a clamping boss 3211 that is limitedly matched with the limiting boss 22, the first end of the third elastic member 323 abuts against the limiting boss 22, and the second end of the third elastic member 323 abuts against the clamping block 322. With the above structure, the second end of the second contact 20 is provided with a limiting boss 22, the clamping boss 3211 of the connecting pin 321 is limitedly matched with the limiting boss 22, and the first end of the third elastic member 323 abuts against the limiting boss 22, and the second end of the third elastic member 323 abuts against the clamping block 322, so that the third elastic member 323 can play a resetting role when the connecting pin 321 moves, and the limiting boss 22 can prevent the connecting pin 321 from being separated from the second end of the second contact 20.

[0042] It should be noted that, except for the middle position of the second contact 20 , the other parts are respectively the first end of the second contact 20 and the second end of the second contact 20 .

[0043] like Figure 2 and Figure 3 As shown, the block 322 includes a first guide bevel 3221 and a first engaging surface 3222, the locking block 312 includes a second guide bevel 3122 and a second engaging surface 3123, the inclination direction of the first guide bevel 3221 is the same as the inclination direction of the second guide bevel 3122, when the first contact 10 extends into the recessed cavity 21, the first guide bevel 3221 and the second guide bevel 3122 slide in cooperation, and the moving member 32 switches from the extended state to the avoidance state, when the first contact 10 extends into the recessed cavity 21, and the moving member 32 switches from the avoidance state to the extended state, the block 322 is located between the moving block 313 and the locking block 312, and the first engaging surface 3222 engages in cooperation with the second engaging surface 3123. With the above structure, the first guide bevel 3221 of the locking block 322 can slide and cooperate with the second guide bevel 3122 of the locking block 312, and then when the second end of the first contact 10 extends into the recessed cavity 21 of the second contact 20, the first guide bevel 3221 cooperates with the second guide bevel 3122, and the moving part 32 can be switched from the extended state to the avoidance state, and then the first clamping surface 3222 and the second clamping surface 3123 are clamped and cooperated to ensure the stability of the clamping structure of the first contact 10 and the second contact 20.

[0044] like Figures 2 to 4 As shown, the moving block 313 includes a third guiding bevel 3131. When the second end of the first contact 10 moves toward a direction away from the second end of the second contact 20, the moving block 313 pushes the moving member 32 to switch from the extended state to the avoidance state through the third guiding bevel 3131 and the first guiding bevel 3221. With the above structure, the moving block 313 cooperates with the first guiding bevel 3221 through the third guiding bevel 3131, thereby pushing the moving member 32 to switch from the extended state to the avoidance state, ensuring that the third guiding bevel 3131 can cooperate with the first guiding bevel 3221, thereby ensuring that the first contact 10 and the second contact 20 are disassembled, making the disassembly method convenient.
