Description

Technical Field

[0001] The present invention relates to the technical field of electric tools, and more particularly to a quick cable connection device. Background Art

[0002] Cables have different sizes and specifications. Some cables have thicker conductive cores and higher hardness, making them difficult to bend. This requires a very large torque to be used to bend these cables when connecting them, making the operation very inconvenient.

[0003] In addition, in the prior art, it is very inconvenient to connect cables to other devices. For example, when connecting power cables and circuit breakers, the cables are usually inserted into copper noses for crimping. This connection method is complicated to operate, and it is difficult to restrain the cables in a small space. The copper noses and equipment are stressed and difficult to be tightly connected for a long time. Moreover, the cable joints are prone to heat and burn under rated current operation. Alternatively, the conductive core is inserted into the hole, and then the conductive core is fixed by tightening the bolts, thereby fixing and connecting the cables. Although this connection method is easy to operate, once the bolts are loosened over time, the cable joints are prone to heat and burn. Summary of the invention

[0004] The present invention overcomes three deficiencies in the prior art: (1) for cables with higher hardness, it is very inconvenient when the cables need to be bent; (2) the power cable is connected by crimping with a copper nose, which is very inconvenient for cables with large diameters, such as cables with a diameter of more than 120 square millimeters. At the same time, once the fixing bolts are slightly loose or the contact surface is not in contact, the power cable connection is prone to heat up; (3) when repairing a burned joint, it cannot be repaired quickly and the entire cable must be replaced. A cable quick connection device is provided, which can be bent at any angle, so that the cable can be conveniently connected to any device without bending, and the cable is also very convenient to install, and the cable and the device can be quickly connected, thereby improving the work efficiency of connecting the cables.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a cable quick connection device, comprising: a bendable flexible conductive part, a device connection part arranged at one end of the flexible conductive part, and a cable connection assembly arranged at the other end of the flexible conductive part; The cable connection assembly comprises a connection outer sleeve and a connection inner sleeve, a conductive assembly is arranged in the connection inner sleeve, and a pushing assembly is arranged in the connection outer sleeve; The cable is inserted into the connecting inner sleeve, the connecting inner sleeve cooperates with the connecting outer sleeve, and the pushing component pushes the conductive component to fit tightly against the outer periphery of the cable to fix the cable.

[0006] In the present invention, the cable quick connection device is arranged into three parts, namely, the equipment connection part, the cable connection assembly and the flexible conductive part.

[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 4 As shown, a cable quick connection device comprises: a bendable flexible conductive part 1, a device connection part 2 arranged at one end of the flexible conductive part 1 and a cable connection assembly arranged at the other end of the flexible conductive part 1.

[0032] The cable connection component comprises a connection outer sleeve 3 and a connection inner sleeve 4 , a conductive component 5 is arranged in the connection inner sleeve 4 , and a pushing component 6 is arranged in the connection outer sleeve 3 .

[0033] The cable is inserted into the connecting inner sleeve 4, the connecting inner sleeve 4 cooperates with the connecting outer sleeve 3, and the pushing component 6 pushes the conductive component 5 to fit tightly against the outer periphery of the cable to fix the cable.

[0034] In the present application, the cable quick connection device is arranged into three parts, namely, the equipment connection part 2, the cable connection assembly and the flexible conductive part 1. The arrangement of the flexible conductive part 1 enables the cable connection assembly and the equipment connection part 2 to be installed and connected at any angle, so that after the cable and the cable connection assembly are installed, they can be bent through the flexible connection part to connect with other equipment; the equipment connection part 2 can be conveniently fixedly connected with other equipment. In addition, in the present application, the cable connection assembly is arranged as a connecting outer sleeve 3 and a connecting inner sleeve 4, so that after the cable is inserted into the connecting inner sleeve 4, the connecting outer sleeve 3 and the connecting inner sleeve 4 are fixedly matched, and the pushing assembly 6 pushes the conductive assembly 5 to be close to the periphery of the cable, so that the conductive assembly 5 plays a role in fixing the cable and conducting electricity, thereby facilitating the installation of the cable. Therefore, in summary, in the present application, after the cable and the cable connection assembly are installed, the flexible connection part can be bent at any angle, so that the cable can be connected to other equipment without bending, and the cable connection assembly can fix the cable by directly inserting the cable, which has the characteristic of being very convenient to connect the cable.

[0035] Example 2: Reference Figures 1 to 4 As shown, a cable quick connection device comprises: a bendable flexible conductive part 1, a device connection part 2 arranged at one end of the flexible conductive part 1 and a cable connection assembly arranged at the other end of the flexible conductive part 1.

[0036] The cable connection component comprises a connection outer sleeve 3 and a connection inner sleeve 4 , a conductive component 5 is arranged in the connection inner sleeve 4 , and a pushing component 6 is arranged in the connection outer sleeve 3 .

[0037] In one embodiment, the outer wall of the connecting inner sleeve 4 is provided with an external thread, and the inner wall of the connecting outer sleeve 3 is provided with an internal thread. The connecting inner sleeve 4 and the connecting outer sleeve 3 are matched with each other through the threads, so that the connecting inner sleeve 4 and the connecting outer sleeve 3 are matched and connected.

[0038] The cable is inserted into the connecting inner sleeve 4, and the connecting inner sleeve 4 cooperates with the connecting outer sleeve 3 through threads. During the process of threaded connection between the connecting inner sleeve 4 and the connecting inner sleeve 4, the pushing component 6 pushes the conductive component 5 to fit tightly against the periphery of the cable, thereby fixing the cable and conducting electricity.

[0039] The conductive assembly 5 in this embodiment includes a plurality of conductive members 51 arranged in the circumferential direction inside the connecting inner sleeve 4 .

[0040] Specifically, an inner sleeve hole 41 is provided in the middle of the connecting inner sleeve 4, and a plurality of conductive members 51 are evenly distributed in the circumferential direction of the inner sleeve hole 41, and the conductive members 51 are provided along the axial direction of the connecting inner sleeve 4. One end of the plurality of conductive members 51 is fixed, and is fixed as a fixed end 511; the other end of the conductive member 51 can be bent by the action of the pushing component 6, and the other end of the conductive member 51 is a movable end 512. It should be noted that, in this embodiment, the fixed ends 511 of the plurality of conductive members 51 are closely arranged to form a circular ring; and at the movable end 512 of the conductive member 51, since the conductive member 51 will be deformed toward the axis after being acted upon by the pushing component 6, a certain gap is provided between the movable ends 512 of adjacent conductive members 51, so that the conductive member 51 can be bent toward the axis direction of the connecting inner sleeve 4 by the action of the pushing component 6.

[0041] In one embodiment, the conductive member 51 is a conductive sheet, and several conductive sheets are arranged along the axial direction of the connecting inner sleeve 4. The conductive sheet can be bent and shrunk to wrap the wire, and has good conductive performance. A limit clamping strip 55 is penetrated at the center of the conductive sheet, and the limit clamping strip 55 is arranged along the radial direction of the connecting inner sleeve 4. A perforation 42 is also provided on the side wall of the connecting inner sleeve 4, and the limit clamping strip 55 is also penetrated in the perforation 42. The limit clamping strip 55 plays a role in fixing the conductive sheet, and can prevent the conductive sheet from falling off from the connecting inner sleeve 4 while ensuring that the conductive sheet can bend along the radial direction of the connecting inner sleeve 4.

[0042] The conductive component 5 further includes an insulating isolation sleeve 52 disposed on the periphery of the plurality of conductive members 51 ; the insulating isolation sleeve 52 is disposed on the periphery of the fixed end 511 of the conductive member 51 , and the insulating isolation sleeve 52 isolates the plurality of conductive members 51 from the connecting sleeve 3 .

[0043] The insulating isolation sleeve 52 has at least two effects: (1) The insulating isolation sleeve 52 binds and fixes one end of the plurality of conductive members 51. After the wire is inserted, it can freely shrink 360 degrees to wrap the wire, so that the plurality of conductive members 51 arranged in a circumferential direction are fixed together, thereby playing the function of fixing the conductive members 51; (2) The insulating isolation sleeve 52 is made of insulating material, including but not limited to rubber material and ceramic material, and is arranged between the plurality of conductive members 51 and the connecting inner sleeve 4, thereby isolating the conductive members 51 and the connecting inner sleeve 4 from each other, thereby playing the role of insulation, thereby playing the function of preventing electric shock.

[0044] In addition, a limiting groove 513 is provided on the outer side wall of the movable end 512 of the conductive member 51. A plurality of limiting grooves 513 are arranged to form a structure similar to a limiting ring. A locking ring 53 is provided on the periphery of the plurality of conductive members 51. The locking ring 53 is arranged in the limiting grooves 513 of the plurality of conductive members 51, that is, the locking ring 53 is arranged in the limiting ring formed by the plurality of limiting grooves 513. A limiting spacer 54 is provided on the periphery of the locking ring 53 to prevent the limiting ring from coming out of the limiting groove 513.

[0045] The limiting ring has the function of fixing and unidirectionally limiting the movable end 512 of the conductive member 51, so that the conductive member 51 can only be bent toward the center direction of the inner cylinder, and when the conductive member 51 loses the force from the pushing assembly 6, the conductive member 51 automatically resets, and the limiting groove 513 abuts against the limiting ring again. In addition, the limiting spacer 54 is also made of insulating material, including but not limited to rubber material.

[0046] The pushing component 6 includes a radial pushing member arranged on the periphery of the conductive component 5; the inner side wall of the connecting sleeve 3 is provided with a guide portion cooperating with the radial pushing member. When the connecting sleeve 3 and the connecting inner sleeve 4 are connected, the connecting sleeve 3 drives the radial pushing member and the conductive portion to cooperate, and the radial pushing member contracts inwardly in the radial direction to push the conductive component 5 to fix the cable.

[0047] In one embodiment, the radial pusher is a conical sleeve 61 disposed on the periphery of the conductive component 5, and the side wall of the conical sleeve 61 is provided with an open groove 611 along its axial direction; the guide portion is a conical guide surface 32 that cooperates with the conical sleeve 61. The center of the connecting outer sleeve 3 is provided with an outer sleeve hole 31, and the connecting inner sleeve 4 is provided in the outer sleeve hole 31 of the connecting outer sleeve 3. The end of the outer sleeve hole 31 away from the connecting inner sleeve 4 is provided with a limit push ring 33 that contracts in the radial direction inward, and the circumferential direction of the end of the conical sleeve 61 close to the limit push ring 33 is provided with a limit push platform 612, and the limit push ring 33 cooperates with the limit push platform 612, so that when the connecting outer sleeve 3 and the connecting inner sleeve 4 are rotated to cooperate, the connecting outer sleeve 3 cooperates with the connecting inner sleeve 4 along the axial direction, and the limit push ring 33 of the connecting outer sleeve 3 can cooperate with the limit push platform 612, so as to push the conical sleeve 61 to move. Furthermore, the limiting push ring 33 and the limiting spacer 54 are engaged with each other, thereby preventing the limiting spacer 54 from falling off.

[0048] In the process of the connecting outer sleeve 3 pushing the conical sleeve 61 and the conical guide surface 32 to cooperate, as the conical sleeve 61 and the conical guide surface 32 cooperate, the conical sleeve 61 can shrink toward the axial direction of the connecting inner sleeve 4, thereby pushing the conductive member 51 to move toward the axial direction, so that the conductive member 51 can be closely attached to the stable circumferential direction of the cable and lock the cable.

[0049] The flexible conductive part 1 includes a plurality of flexible wires 11 and an intermediate connecting part 12 for fixing the plurality of flexible wires 11 together. The outer periphery of the flexible wires 11 is covered with a rubber insulating sleeve. The number of flexible wires 11 corresponds to the number of conductive members 51, and each flexible wire 11 cooperates with the conductive member 51. The number of flexible wires 11 and conductive members 51 in this embodiment is set to eight. The intermediate connecting part 12 is used to fix the plurality of flexible wires 11 together, so that the plurality of wires are more neat and the force is more uniform. In actual use, its length is set according to requirements. The other end of the plurality of wires is fixed and electrically connected to the device connecting part 2, so that the electrical energy on the conductive member 51 can be transferred to the device connecting part 2.

[0050] The working principle of this embodiment is as follows: First, the device connecting part 2 is connected to the relevant device so that the cable quick connecting device can be connected to the relevant device.

[0051] Secondly, rotate the connecting outer sleeve 3 so that the conical sleeve 61 and the conical guide surface 32 move away from each other, so that the conductive member 51 is reset; then insert the conductive core in the cable into the connecting inner sleeve 4, and the outer periphery of the conductive core is not completely in contact with the conductive member 51.

[0052] Finally, the connecting sleeve 3 is rotated. During the rotation of the connecting sleeve 3, the connecting sleeve 3 moves along the axial direction toward the connecting inner sleeve 4. At this time, the connecting sleeve 3 pushes the conical sleeve 61 and the conical guide surface 32 to cooperate. In this process, as the conical sleeve 61 and the conical guide surface 32 cooperate, the conical sleeve 61 can shrink toward the axial direction of the connecting inner sleeve 4, thereby pushing the conductive member 51 to move toward the axial direction, so that the conductive member 51 can be closely attached to the circumferential direction of the conductive core, and the cable is locked to prevent the cable from being separated from the connecting inner sleeve 4.

[0053] Therefore, the cable quick connection device is divided into three parts in the present application, namely, the device connection part 2, the cable connection assembly and the flexible conductive part 1. The setting of the flexible conductive part 1 enables the cable connection assembly and the device connection part 2 to be installed and connected at any angle, so that after the cable and the cable connection assembly are installed, they can be bent through the flexible connection part to connect with other devices; the device connection part 2 can be conveniently fixedly connected with other devices.

[0054] In addition, in the present application, the cable connection assembly is configured to be a connecting outer sleeve 3 and a connecting inner sleeve 4, so that after the cable is inserted into the connecting inner sleeve 4, the connecting outer sleeve 3 and the connecting inner sleeve 4 are fixedly matched, and the pushing member pushes the conductive member 51 tightly against the periphery of the cable, so that the conductive member 51 not only plays a role in fixing the cable, but also plays a role in conducting electricity, thereby facilitating the installation between the cable and the cable quick connection assembly.

[0055] Therefore, in summary, in the present application, after the cable and the cable connecting assembly are installed, the flexible connecting portion can be bent at any angle, so that the cable can be connected to other devices without bending, and the cable connecting assembly can allow the cable to be directly inserted, which is very convenient for connecting cables.

[0059] The cable is inserted into the connecting inner sleeve 4, and the connecting inner sleeve 4 cooperates with the connecting outer sleeve 3 through threads. During the process of threaded connection between the connecting inner sleeve 4 and the connecting inner sleeve 4, the pushing component 6 pushes the conductive component 5 to fit tightly against the periphery of the cable, thereby fixing the cable and conducting electricity.

[0060] The conductive assembly 5 in this embodiment includes a plurality of conductive members 51 arranged in the circumferential direction inside the connecting inner sleeve 4 .

It should be noted that, in this embodiment, the fixed ends 511 of the plurality of conductive members 51 are closely arranged to form a circular ring; and at the movable end 512 of the conductive member 51, since the conductive member 51 will be deformed toward the axis after being acted upon by the pushing component 6, a certain gap is provided between the movable ends 512 of adjacent conductive members 51, so that the conductive member 51 can be bent toward the axis direction of the connecting inner sleeve 4 by the action of the pushing component 6.

A perforation 42 is also provided on the side wall of the connecting inner sleeve 4, and the limit clamping strip 55 is also penetrated in the perforation 42. The limit clamping strip 55 plays a role in fixing the conductive sheet, ensuring that the conductive sheet can be bent along the radial direction of the connecting inner sleeve 4, while preventing the conductive sheet from falling off the connecting inner sleeve 4.

[0063] The conductive component 5 further includes an insulating isolation sleeve 52 disposed on the periphery of the plurality of conductive members 51 ; the insulating isolation sleeve 52 is disposed on the periphery of the fixed end 511 of the conductive member 51 , and the insulating isolation sleeve 52 isolates the plurality of conductive members 51 from the connecting sleeve 3 .

A limiting spacer 54 is provided on the periphery of the locking ring 53 to prevent the limiting ring from coming out of the limiting groove 513.

[0066] The limiting ring has the function of fixing and unidirectionally limiting the movable end 512 of the conductive member 51, so that the conductive member 51 can only be bent toward the center direction of the inner cylinder, and when the conductive member 51 loses the force from the pushing assembly 6, the conductive member 51 automatically resets, and the limiting groove 513 abuts against the limiting ring again.

The number of flexible wires 11 corresponds to the number of conductive members 51, and each flexible wire 11 cooperates with a conductive member 51. The number of flexible wires 11 and conductive members 51 in this embodiment is set to eight. The intermediate connecting part 12 is used to fix the plurality of flexible wires 11 together, so that the plurality of wires are more orderly, the force is evenly applied and the conduction is uniform, and the length thereof is set according to the specific requirements during actual use. The other ends of the plurality of wires are fixed and electrically connected to the device connecting part 2, so that the electrical energy on the conductive member 51 can be transferred to the device connecting part 2.

[0071] In this embodiment, the pushing assembly 6 also includes an insulating pushing sleeve 62, which is arranged on the periphery of the radial pushing member, and the insulating pushing sleeve 62 isolates the radial pushing member and the connecting sleeve 3. The materials used for the insulating pushing sleeve 62 in this embodiment include but are not limited to insulating materials. In this embodiment, the insulating pushing sleeve 62 and the conical sleeve 61 have similar structures, and the insulating sleeve is fitted on the periphery of the conical sleeve 61. The insulating pushing sleeve 62 isolates the conical sleeve 61 from the connecting sleeve 3, thereby preventing the connecting sleeve 3 from leaking electricity.

[0072] In this embodiment, by providing an insulating push sleeve 62, the insulating push sleeve 62, the insulating isolation sleeve 52 and the limiting isolation sleeve 54 cooperate to prevent the conductive member 51 and the connecting outer sleeve 3 and the connecting inner sleeve 4 from being insulated from each other; this plays an insulating role, effectively preventing the leakage of electric energy, and further preventing the occurrence of electric shock accidents. In addition, the connecting inner sleeve 4 and the connecting outer sleeve 3 in this application are also made of insulating materials, and the connecting inner sleeve 4 and the connecting outer sleeve 3 include but are not limited to ceramics, plastics and other materials.

[0073] The working principle of this embodiment is as follows: First, the device connecting part 2 is connected to the relevant device so that the cable quick connecting device can be connected to the relevant device.

[0074] Secondly, rotate the connecting outer sleeve 3 so that the conical sleeve 61 and the conical guide surface 32 move away from each other, so that the conductive member 51 is reset; then insert the conductive core in the cable into the connecting inner sleeve 4, and the outer periphery of the conductive core is not completely in contact with the conductive member 51.

[0075] Finally, the connecting sleeve 3 is rotated. During the rotation of the connecting sleeve 3, the connecting sleeve 3 moves along the axial direction toward the connecting inner sleeve 4. At this time, the connecting sleeve 3 pushes the conical sleeve 61 and the conical guide surface 32 to cooperate. In this process, as the conical sleeve 61 and the conical guide surface 32 cooperate, the conical sleeve 61 can shrink toward the axial direction of the connecting inner sleeve 4, thereby pushing the conductive member 51 to move toward the axial direction, so that the conductive member 51 can be closely attached to the circumferential direction of the conductive core, and the cable is locked to prevent the cable from being separated from the connecting inner sleeve 4.

[0076] Therefore, the cable quick connection device is divided into three parts in the present application, namely, the device connection part 2, the cable connection assembly and the flexible conductive part 1. The setting of the flexible conductive part 1 enables the cable connection assembly and the device connection part 2 to be installed and connected at any angle, so that after the cable and the cable connection assembly are installed, they can be bent through the flexible connection part to connect with other devices; the device connection part 2 can be conveniently fixedly connected with other devices.

[0077] In addition, in the present application, the cable connection assembly is configured to be a connecting outer sleeve 3 and a connecting inner sleeve 4, so that after the cable is inserted into the connecting inner sleeve 4, the connecting outer sleeve 3 and the connecting inner sleeve 4 are fixedly matched, and the pushing member pushes the conductive member 51 tightly against the periphery of the cable, so that the conductive member 51 not only plays a role in fixing the cable, but also plays a role in conducting electricity, thereby facilitating the installation between the cable and the cable quick connection assembly.

[0078] Therefore, in summary, in the present application, after the cable and the cable connecting assembly are installed, the flexible connecting portion can be bent at any angle, so that the cable can be connected to other devices without bending, and the cable connecting assembly can allow the cable to be directly inserted, which is very convenient for connecting cables.

[0079] Embodiment 4: This embodiment is similar in structure to Embodiment 1 or Embodiment 2, except that the device connection portion 2 includes a connection terminal piece 21, and a plurality of flexible wires 11 are connected to the connection terminal piece 21, and the connection method between the head-shaped wire and the connection terminal piece 21 includes but is not limited to welding. The connection terminal piece 21 is provided with a connection terminal hole 22, and the setting of the connection terminal hole 22 facilitates the connection between the connection terminal piece 21 and the relevant equipment; the connection terminal piece 21 is also provided with an auxiliary connection block 23, and the auxiliary connection block 23 is provided with an auxiliary connection hole 24, and the side wall of the auxiliary connection hole 24 is penetrated by an auxiliary threaded hole, and an auxiliary screw 25 is threadedly connected in the auxiliary threaded hole.

[0080] In one embodiment, the connecting terminal piece 21 is composed of two conductive sheets that are bonded together. A plug hole 26 is provided on the connecting terminal piece 21. The auxiliary connecting block 23 cooperates with the plug hole 26 in a plug-in manner, thereby fixing the auxiliary connecting block 23 on the connecting terminal piece 21, so that the auxiliary connecting block 23 and the connecting terminal piece 21 can be installed or separated according to actual needs.

[0081] The auxiliary connection hole 24 is convenient for connecting with a ground wire or other auxiliary wires. The auxiliary wire is inserted into the auxiliary connection hole 24 , and then the auxiliary screw 25 is rotated to fix the auxiliary wire in the auxiliary connection hole 24 .

[0082] Example 5: The structure of this example is similar to that of Example 1 to Example 2 or Example 3 or Example 4, except that a temperature sensor is provided in the middle connecting portion 12. When the current is too large and the temperature of the flexible wire 11 is too high, a signal is sent to remind the staff to inspect the relevant equipment.
