Description

Technical Field

[0001] The present invention relates to the technical field of conductive connection, and in particular to a cable connection assembly and a cable device. Background Art

[0002] Cable is an electrical product used to transmit electrical energy, signals or realize electromagnetic energy conversion. It is usually composed of a conductive core, an insulating layer, a sheath and an outer sheath. The structure and material of the cable will vary according to different application requirements. The plug installed on the cable is usually called a cable plug or connector. These connectors are designed to establish electrical connections between cables or between cables and other electrical equipment.

[0003] A Chinese patent document with announcement number CN117175295B discloses a cable quick-connect plug, including a cable, a shell and a conductive column. A splitting mechanism and a connecting mechanism are arranged in the shell. A through hole is opened at one end of the shell, and the cable passes through the through hole to enter the shell. The splitting mechanism includes a slice, a first arc guide plate, a second arc guide plate and a conical guide block. The slice is used to cross-cut the core of the cable and cut the outer skin of the core to put the cable and the conductive column in a state of communication. The first arc guide plate and the second arc guide plate can strip the outermost layer of the cable. The conical guide block can separate the three battery cells from each other. The connecting mechanism is used to press the conductive column and the battery cell tightly. During installation, the cable is manually pushed into the shell, the outer skin of the cable is cut by the splitting mechanism in the shell, and then the battery cell and the conductive column are connected together by the connecting mechanism.

[0004] In the above technology, the cable is manually pushed into the cable plug, and the outer skin of the cable is cut by the pushing action. Therefore, the outer skin of the cable with a thicker diameter needs to be cut off when installing the plug. Since the outer skin of the cable with a thicker diameter is thicker and harder, it is not convenient to cut, resulting in low installation efficiency. Summary of the invention

[0016] The effect is that the driving wheel contacts the cable only after the outer shell is put on the cable, which makes it easy to put the outer shell on the cable.

[0017] Preferably, a plurality of protrusions are provided on the driving wheel along the circumference of the driving wheel, and the protrusions are used to increase the friction between the driving wheel and the outer sheath of the cable.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1 and Fig.10 As shown, the cable connection assembly of the present invention includes a shell 2, a conductive column 3, a mounting assembly 4 and a connecting assembly 5. The right end of the shell 2 is open, and an end cover 27 for closure is installed on the left end. Three conductive columns 3 are inserted into the end cover 27, and the three conductive columns 3 are evenly distributed on the end cover 27 around the axis of the shell 2. The mounting assembly 4 is arranged at the right end of the shell 2. When the cable 1 is inserted into the shell 2 from the right end of the shell 2, the mounting assembly 4 will drive the shell 2 to move along the axial direction of the cable 1, so that the shell 2 is sleeved on the cable 1. The connecting assembly 5 is arranged on the shell 2. When the shell 2 moves along the axial direction of the cable 1, the conductive column 3 is connected to the battery core of the cable 1 through the connecting assembly 5.

[0039] like Figure 1-Figure 6As shown, the connection assembly 5 includes a screw 1 51, a telescopic frame 52, a gear 2 55 and a driving unit. The telescopic frame 52 is slidably mounted on the right end surface of the end cover 27 along the axial direction of the housing 2. An elastic member 1 510 for moving the telescopic frame 52 to the right is installed between the telescopic frame 52 and the end cover 27. A mounting plate is provided at the right end of the telescopic frame 52. The right end of the conductive column 3 is rotatably mounted on the mounting plate. The left end of the screw 1 51 passes through the mounting plate and is fixedly connected to the right end of the conductive column 3. The screw 1 51 is coaxial with the conductive column 3. Two auxiliary screws 2 59 are also rotatably mounted on the side of the single screw 1 51. The screw 2 59 is used to improve the conductivity of the conductive column 3 and the battery cell. The screw 2 59 and the screw 1 51 are both equipped with a gear 3. 511, when the screw 1 51 rotates, the two screws 2 59 are driven to rotate through the gear 3 511, and the three gears 2 55 are rotatably installed on the right end surface of the end cover 27. The three gears 2 55 are respectively sleeved on the three conductive columns 3, and the gears 2 55 and the conductive columns 3 are connected by splines. In the initial state, the elastic member 1 510 makes the mounting plate away from the end cover 27, so that the screw 1 51 at the right end of the conductive column 3 exceeds the right end of the shell 2, so that it is convenient to align the right end of the screw 1 51 with the gap between the wires in the battery cell, and the driving unit drives the gear 1 54 to rotate, thereby driving the screw 1 51 and the screw 2 59 to rotate, so that the screw 1 51 and the screw 2 59 rotate and drill into the battery cell, thereby connecting the conductive column 3 and the battery cell.

[0040] like Figure 1-Figure 6 As shown, the driving unit includes a driving ring 53, a gear 54 and a gear ring 56. The housing 2 is provided with a ring groove 24, the driving ring 53 is sleeved on the ring groove 24, and the driving ring 53 can slide along the axial direction of the ring groove 24. The driving ring 53 is provided with a plurality of anti-slip grooves along the circumferential direction of the driving ring 53. The gear ring 56 is installed on the left end face of the driving ring 53. The three gears 54 are rotatably installed on the right end face of the end cover 27. The outer circumferential surface of the housing 2 is provided with three through holes. The outer side of the gear 54 passes through the through holes and meshes with the gear ring 56. The wheel 1 54 is meshed with the gear 2 55 in a one-to-one correspondence, and a limit ring 23 is installed in the annular groove 1 24 to limit the distance that the drive ring 53 moves to the right on the housing 2, thereby preventing the gear ring 56 from being disengaged from the gear 1 54. A plurality of limit blocks 57 are installed on the left end face of the drive ring 53, and a plurality of grooves 58 matching the limit blocks 57 are provided on the left end face of the annular groove 1 24. In the initial state, the left end face of the drive ring 53 is tightly attached to the left end face of the annular groove 1 24, and the limit block 57 is inserted in the groove 58, so that the drive ring 53 cannot rotate.

[0041] like Figure 1-Figure 9As shown, the mounting assembly 4 includes a swivel 41, a driving wheel 42, a bracket 43, and a wedge-shaped guide groove 45. The swivel 41 is sleeved on the right side of the housing 2, and the left side of the swivel 41 is penetrated on the right side of the driving ring 53. The left side of the swivel 41 and the right side of the driving ring 53 are connected by a spline, so that the two can only slide relative to each other along the axial direction of the swivel 41. A thread groove 22 is also provided in the annular groove 1 24. A thread 46 matching the thread groove 22 is provided on the inner circumferential surface of the swivel 41. A ring groove 26 is provided at the left end of the thread groove 22. When the housing 2 is installed, when the driving ring 53 drives the swivel 4 When the rotating ring 41 rotates, the thread 46 on the rotating ring 41 rotates in the thread groove 22, and the thread 46 moves from the right end of the thread groove 22 to the left end, thereby driving the rotating ring 41 to move leftward in the ring groove 1 24. After the thread 46 enters the ring groove 26, the rotating ring 41 drives the thread 46 to continue to rotate, and the thread 46 idles in the ring groove 26. An elastic member 3 44 is installed between the left end of the rotating ring 41 and the right end of the driving ring 53 to keep the two away from each other, so that the right end of the thread 46 presses against the left end of the thread groove 22, and the inner circumferential surface of the rotating ring 41 slides along the radial direction of the rotating ring 41. A bracket 43 is rotatably mounted, and a plurality of brackets 43 are evenly distributed along the inner circumference of the rotating ring 41. An elastic member 47 is installed between the bracket 43 and the rotating ring 41. The elastic member 47 is used to pull the bracket 43 and the rotating ring 41 closer to each other. A driving wheel 42 is rotatably mounted on the bracket 43. The rotation axis of the driving wheel 42 is inclined relative to the length direction of the rotating ring 41. A wedge-shaped guide groove 45 is provided at the left end of the bracket 43. The wedge-shaped guide groove 45 consists of an inclined section and a horizontal section. An annular boss 21 matching the wedge-shaped guide groove 45 is also provided on the housing 2. When the driving ring 53 rotates, the screw 53 is driven. When the rotating ring 41 rotates and drills into the battery core, the driving ring 53 will also drive the rotating ring 41 to rotate through the spline between the rotating ring 41. When the rotating ring 41 rotates, it will first move to the left on the housing 2 through the thread groove 22. When the rotating ring 41 moves to the left, the wedge-shaped guide groove 45 will gradually fit on the annular boss 21. Due to the guidance of the inclined section, the bracket 43 will slide inward along the radial direction of the rotating ring 41. At this time, the driving wheel 42 gradually fits tightly against the outer surface of the cable 1. When the driving wheel 42 fits tightly against the outer surface of the cable 1, the rotating ring 41 continues to rotate and drives the housing 2 to gradually fit on the cable 1 from left to right.

[0042] like Figure 1 and Figure 4 As shown, a fixing rod 25 is slidably installed in the end cover 27 along the radial direction of the outer shell 2. When installing the outer shell 2, the fixing rod 25 is first pulled outward from the end cover 27, and then the fixing rod 25 is held by hand to fix the outer shell 2 through the fixing rod 25 to prevent the outer shell 2 from rotating. A conical expansion opening is provided at the right end of the outer shell 2 to facilitate the outer shell 2 to be put on the cable 1.

[0043] The specific working principle of the present invention is:

[0044] First, put the shell 2 on the cable 1 from the left side, and align the right ends of the screws 1 51 and 2 59 into the gap between the wires in the battery cell, then pull the drive ring 53 to the right to unlock the drive ring 53, hold the fixing rod 25 with your hand, and then rotate the drive ring 53 to drive the swivel 41 to rotate. When the swivel 41 rotates, it moves to the left first. After the wedge-shaped guide groove 45 is gradually sleeved on the annular boss 21, due to the guidance of the inclined section, the bracket 43 will slide inward along the radial direction of the swivel 41. At this time, the drive wheel 42 gradually fits tightly against the outer surface of the cable 1. When the drive wheel 42 fits tightly against the outer surface of the cable 1, the swivel 41 continues to rotate and drives the shell 2 It is gradually sleeved on the cable 1 from left to right. At this time, the housing 2 moves to the right, which will drive the telescopic frame 52 to move to the right through the end cover 27. The telescopic frame 52 moves to the right and pushes the screw 1 51 and the screw 2 59 to move to the right. At the same time, when the drive ring 53 rotates, it will drive the gear 1 54 to rotate through the gear ring 56. The rotation of the gear 1 54 will drive the gear 2 55 to rotate. The rotation of the gear 2 55 will drive the screw 1 51 to rotate. The rotation of the screw 1 51 will drive the screw 2 59 to rotate through the gear 3 511. At this time, the screw 1 51 and the screw 2 59 are gradually rotated and drilled into the battery cell under the drive of the surface threads and the thrust of the telescopic frame 52 moving to the right, so as to realize the connection between the conductive column 3 and the battery cell.

[0045] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
