Technical Field

[0001] The present application relates to the technical field of wiring terminals, and in particular to a wiring terminal for a new energy charging device. Background Art

[0002] With the rapid development of the new energy vehicle industry, the demand for new energy charging equipment is increasing. As an important part of charging equipment, the connection between new energy charging wires and terminal blocks is frequently operated during processing and maintenance.

[0003] The connection between existing terminals and wires usually relies on crimping equipment. After the conductive segment of the wire stripped of the insulation layer extends into the terminal, the equipment crimps the crimping area of ​​the terminal with the conductive segment of the wire to achieve electrical connection. However, new energy charging equipment may need to be charged in a variety of environments, including outdoors, construction sites, and homes. In these environments, there may be temporary situations where there is no crimping equipment during maintenance, and the above-mentioned connection method has many inconveniences when there is no equipment temporarily, which limits the flexibility of the application scenarios of the terminal. Summary of the invention

[0004] In order to improve the flexibility of the wiring terminal, the present application provides a wiring terminal for a new energy charging device.

[0005] The present application provides a wiring terminal for a new energy charging device, which adopts the following technical solution: A wiring terminal for a new energy charging device comprises a terminal body, one end of the terminal body is a plug-in section, a free end of the plug-in section extends inwardly to form a plug-in cavity for inserting the wire; the free end of the plug-in section is provided with rotating pieces at intervals along the circumference of the plug-in section, the rotating pieces rotate on the plug-in section, and a side of the rotating piece facing the axis of the plug-in section is provided with a limiting tooth; A movable sleeve is coaxially sleeved on the plug-in section and threadedly connected. When the movable sleeve moves toward the rotating piece, the rotating piece can be pressed toward the wire, so that the limiting teeth are embedded in the insulating layer of the wire.

[0006] By adopting the above technical solution, the rotating piece can be pressed toward the wire under the push of the movable sleeve, and the limiting teeth thereon are embedded in the insulating layer of the wire, so as to stably fix the wire, thereby improving the applicability and flexibility of the terminal block in a variety of environments, especially when there is no temporary crimping equipment, the wire connection can still be conveniently performed.

[0007] Optionally, the rotating piece includes a first part, a second part and a bending part; the bending part is bent and rotates on the plug-in section; the first part and the second part are respectively arranged at two ends of the bending part that are far away from each other, and the limiting tooth is arranged on the second part, and the rotating piece cooperates with the movable sleeve through the first part.

[0008] Optionally, the movable sleeve comprises a threaded section and a rotation-limiting section sequentially arranged along a direction close to the rotating piece; the threaded section is threadedly moved on the plug-in section, the rotation-limiting section slides axially on the plug-in section along the plug-in section, and the threaded section coaxially rotates on the position-limiting section; A connecting rope is connected between the rotation limiting section and the first part; when the rotation limiting section moves until the connecting rope is in a stretched state, the moving sleeve is separated from the first part, and the connecting rope pulls the rotating piece until the limiting tooth is separated from the wire.

[0009] By adopting the above technical solution, when the limiting section of the connecting rope moves to the connecting rope in a straightened state, the rotating piece can be pulled until the limiting teeth are separated from the wire, thereby conveniently releasing the connection of the wire and improving the convenience of operation.

[0010] Optionally, the outer wall of the plug-in section has a guide portion, and the rotation limiting section has a guide groove for the guide portion to slide axially along the plug-in section.

[0011] By adopting the above technical solution, the guide portion of the outer wall of the plug-in section cooperates with the guide groove of the rotation-limiting section, so that the rotation-limiting section can stably slide axially along the plug-in section, reducing the shaking or deflection of the movable sleeve during movement.

[0012] Optionally, the plug-in cavity includes a conductive cavity and an insulating cavity which are sequentially connected along a direction close to the rotating piece, and the inner diameter of the insulating cavity is larger than the inner diameter of the conductive cavity.

[0013] By adopting the above technical solution, when the wire is inserted into the plug-in cavity, it can first enter the insulating cavity for preliminary guidance and then enter the conductive cavity for electrical connection, and the insulating part of the wire remains in the insulating cavity, thereby improving the accuracy and stability of the wire connection.

[0014] Optionally, the plug-in section is connected to a conductive sheet in the plug-in cavity, one end of the conductive sheet is connected to the inner wall of the plug-in cavity, the other end of the conductive sheet extends around the circumference of the plug-in cavity and then passes through the plug-in section, and the conductive sheet is located in most of the plug-in section to form a matching cavity for the conductive section of the wire to extend into; A linkage is provided between the end of the movable sleeve away from the rotating piece and the plug-in section. When the movable sleeve moves toward the rotating piece, the linkage can drive the portion of the conductive sheet extending out of the plug-in section to be arranged circumferentially around the plug-in section, so as to pull the conductive sheet in the plug-in section to tighten and clamp the wire.

[0015] By adopting the above technical solution, through the coordination of structures such as the conductive sheet and the linkage, the movable sleeve can simultaneously drive the conductive sheet to be wound around and tightened along the circumference of the plug-in section during the movement process, thereby tightening the conductive section of the wire and realizing the electrical connection and fixation of the wire.

[0016] Optionally, the movable sleeve has a travel groove extending along its circumference at one end away from the rotating piece, and the central angle of the travel groove is less than 360°; The linkage member comprises a guide rod and a slip ring; the slip ring is coaxially sleeved and slides on the plug-in section; the length direction of the guide rod is parallel to the axial direction of the plug-in section, and one end of the guide rod is connected to the slip ring, and the end of the guide rod away from the slip ring slides in the travel groove along the circumferential direction of the movable sleeve; the end of the conductive sheet extending out of the plug-in section forms a collar, and the collar is sleeved on the guide rod and can slide along the length direction of the guide rod; When the movable sleeve moves from being away from the rotating piece to contacting the rotating piece, the guide rod slides from one end of the travel groove to the other end of the travel groove; thereafter, when the movable sleeve continues to move in the direction of squeezing the rotating piece, the movable sleeve drives the guide rod to move in the direction close to the rotating piece, and at the same time, the movable sleeve pushes the guide rod to move circumferentially around the plug-in section.

[0017] By adopting the above technical solution, through the cooperation of the travel groove and the guide rod, the movable sleeve can first rotate to contact the rotating piece. In the process of the movable sleeve pressing the rotating piece to drive the rotating piece to rotate, the guide rod and the conductive piece are driven to move circumferentially around the plug-in section, so that the conductive piece is not easily stretched excessively.

[0018] Optionally, when the limiting teeth are embedded in the insulating layer of the wire, the conductive sheet is stretched to clamp the conductive segment of the wire.

[0019] Optionally, a protective ring is coaxially arranged on a side of the slip ring facing the movable sleeve, and the inner diameter of the protective ring is larger than the outer diameter of the plug-in section; when the movable sleeve moves to the point where the limiting tooth is embedded in the insulating layer of the wire, the protective ring encloses the conductive sheet outside the plug-in section.

[0020] By adopting the above technical solution, the protective ring can enclose the conductive sheet outside the plug-in section when the movable sleeve moves to the limiting tooth and embeds into the insulating layer of the wire, thereby protecting the conductive sheet, reducing interference and damage from the external environment, improving the durability and reliability of the terminal, and extending its service life.

[0021] In summary, the present application includes at least one of the following beneficial effects: 1. Through the coordination of the plug-in section, plug-in cavity, rotating piece and movable sleeve, the terminal block can be conveniently connected and repaired in various environments, especially when there is no crimping equipment temporarily, which improves the flexibility and convenience of connection; 2.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-8 This application is described in further detail.

[0025] The present application embodiment discloses a connection terminal for a new energy charging device. Figure 1 The wiring terminal of the new energy charging equipment includes a terminal body 1, and the tail end of the terminal body 1 is a plug-in section 2 for connecting a wire.

[0026] Reference Figure 2 The free end of the plug section 2 is provided with a plug cavity 3 inwardly, so that the plug section 2 is cylindrical. Specifically, the plug cavity 3 includes a conductive cavity 31 and an insulating cavity 32 which are connected and coaxial in sequence near the free end of the plug section 2. The axial extension length of the plug section 2 in the conductive cavity 31 is greater than the axial extension length of the plug section 2 in the insulating cavity 32, and the inner diameter of the plug section 2 in the conductive cavity 31 is smaller than the inner diameter of the plug section 2 in the insulating cavity 32.

[0027] When the wire (not shown in the figure) is used, the insulation layer is stripped off at the front end to form a bare conductive segment of the conductive wire. When the wire is matched with the terminal, the wire is inserted into the plug-in cavity 3, and the conductive segment of the wire extends into the conductive cavity 31, while the insulating portion of the wire adjacent to the conductive segment enters the insulating cavity 32. The shrinkage of the conductive cavity 31 relative to the insulating cavity 32 limits the insertion of the wire.

[0028] Reference Figure 2 and Figure 3 In order to limit the wire extending into the plug-in section 2, the free end of the plug-in section 2 has a rotating piece 4 for positioning the insulation layer of the wire, and the plug-in section 2 is provided with a conductive piece 10 in the conductive section for tightening the conductive section of the wire. The wire is electrically connected to the terminal through contact with the conductive piece 10.

[0029] Reference Figure 2 and Figure 4 , wherein, for the rotating piece 4, a plurality of rotating pieces 4 are evenly spaced at the end of the plug-in section 2 along the circumference of the plug-in section 2, and each rotating piece 4 can rotate relative to the plug-in section 2. Specifically, a mounting ring 16 is coaxially fixed to the free end of the plug-in section 2, the outer diameter of the mounting ring 16 is smaller than the outer diameter of the plug-in section 2, and the inner diameter of the mounting ring 16 is larger than the inner diameter of the plug-in section 2 in the insulating cavity 32. The mounting ring 16 is cut evenly at intervals along its own circumference to form a rotating shaft 17, and the number and position of the rotating shaft 17 correspond to the rotating piece 4 one by one.

[0030] Reference Figure 4 and Figure 5The rotating piece 4 is made of a hard material, and includes an integrally formed first portion 41, a second portion 42, and a bent portion 43. The first portion 41 and the second portion 42 are both in the shape of a square sheet, the bent portion 43 has an arc-shaped arc opening to be bent, and the bent portion of the bent portion 43 is in an arc shape that fits the outer diameter of the rotating shaft 17. The first portion 41 and the second portion 42 are first formed at two ends of the bent portion 43 that are away from each other.

[0031] After the rotating piece 4 is sleeved onto the corresponding rotating shaft 17 through the bending portion 43, the mounting ring 16 is fixed to the free end of the plug-in section 2, and the first portion 41 is farther away from the central axis of the plug-in section 2 than the second portion 42. A plurality of limiting teeth 5 are fixed on the side of the second portion 42 facing the central axis of the plug-in section 2, and the limiting teeth 5 have a tip facing the central axis of the plug-in section 2, and the distance between the tip of the limiting teeth 5 and the second portion 42 is close to but less than the thickness of the wire insulation layer. Since the insulation layer of the wire is made of rubber, when the rotating piece 4 rotates toward the central axis of the plug-in section 2, the limiting teeth 5 can be inserted into the wire insulation layer, thereby limiting the wire.

[0032] Reference Figure 2 and Figure 3 Therefore, in order to drive the rotating piece 4 to rotate, a moving sleeve 6 is coaxially sleeved and threadedly moved on the plug-in section 2. The moving sleeve 6 is cylindrical, and the moving sleeve 6 includes a threaded section 61 and a rotation-limiting section 62 distributed in sequence along the axial direction of the plug-in section 2 toward the rotating piece 4.

[0033] The threaded section 61 has an internal thread, and the movable sleeve 6 is threadedly moved on the plug-in section 2 through the threaded section 61. The rotation-limiting section 62 is coaxially connected to the end of the threaded section 61 close to the rotating piece 4, and a block-shaped guide portion 8 protrudes outward from the outer peripheral wall of the end of the plug-in section 2 close to the rotating piece 4. A guide groove 9 for the guide portion 8 to press into and slide is provided on the inner wall of the rotation-limiting sleeve along the axial direction parallel to the plug-in section 2. When the threaded section 61 is threadedly moved, the guide portion 8 is driven to slide in the guide groove 9 along the axial direction parallel to the plug-in section 2, thereby limiting the rotation of the rotation-limiting section 62 relative to the plug-in section 2.

[0034] Reference Figure 2 and Figure 4 The end of the rotation-limiting section 62 close to the rotating piece 4 is fixed with a connecting rope 7 corresponding to the rotating piece 4, and the connecting rope 7 is flexible. The end of the connecting rope 7 away from the rotation-limiting section 62 passes through the first part 41 corresponding to the rotating piece 4 and is fixed with a ball 18, the size of which is larger than the size of the hole in the first part 41 for the connecting rope 7 to pass through, so as to limit the connecting rope 7 from being separated from the rotating piece 4 in the direction away from the rotating piece 4.

[0035] When the threaded section 61 moves in a direction away from the rotating piece 4 until the first portion 41 abuts against the end of the plug-in section 2, the threaded section 61 is in an unlocked position, at which time the rotation-limiting section 62 is separated from the first portion 41 with a gap therebetween, and the connecting rope 7 is in a straightened state, and the anti-slip ball 18 abuts against the first portion 41. More importantly, at this time, the second portion 42 extends in a direction away from the plug-in section 2 and in a direction away from the central axis of the plug-in section 2, and the wire will not interfere with the limiting tooth 5 when it is coaxially plugged into the plug-in section 2.

[0036] When the threaded section 61 moves in a direction close to the rotating piece 4, it can drive the limited rotation section 62 to gradually move to abut against the first part 41, and in the process of the limited rotation section 62 continuing to move forward, the limited rotation section 62 gradually presses the first part 41 to move close to the central axis of the plug-in section 2, so as to drive the rotating piece 4 to rotate relative to the rotating shaft 17, so that the second part 42 moves in a direction close to the central axis of the plug-in section 2 until the limiting tooth 5 penetrates the insulation layer of the wire, and the threaded section 61 is in the locked position. In addition, when the terminal needs to be replaced, the threaded section 61 is moved again in a threaded position to the unlocking position, so that the rotating piece 4 can be pulled out of the insulation layer of the wire by the connecting rope 7, so as to release the locking of the terminal on the insulation layer of the wire.

[0037] Reference Figure 2 , Figure 6 and Figure 7 As for the conductive sheet 10, the conductive sheet 10 is in the shape of a long strip, and the conductive sheet 10 is made of a metal material with a certain degree of deformation elasticity. One end of the conductive sheet 10 is fixedly connected to the inner wall of the plug-in section 2 at the plug-in cavity 3, and the other end of the conductive sheet 10 is attached to the inner wall of the plug-in cavity 3 and extends along the circumference of the plug-in cavity 3 for one circle before passing through the plug-in section 2 from the plug-in cavity 3. The plug-in section 2 is provided with an opening for the conductive sheet 10 to extend out.

[0038] When the conductive sheet 10 is attached to the inner wall of the plug cavity 3, the portion of the conductive sheet 10 in the plug cavity 3 forms a matching cavity 11 for the conductive segment of the wire to extend into. When the conductive sheet 10 is pulled toward the outside of the plug segment 2, the portion of the conductive sheet 10 in the plug segment 2 can be gradually shrunk, thereby tightening the conductive segment of the wire, thereby achieving locking and electrical connection between the conductive sheet 10 and the wire.

[0039] Reference Figure 2 and Figure 3 In order to adjust the conductive sheet 10 to a state where the conductive segment of the wire is clamped, the end of the threaded section 61 away from the rotating sheet 4 has a linkage member 12 for driving the conductive sheet 10 to move. Specifically, the linkage member 12 includes a guide rod 121 and a slip ring 122. The slip ring 122 is annular and coaxially slidably sleeved on the plug-in section 2, and the slip ring 122 is farther away from the rotating sheet 4 than the threaded section 61.

[0040] Reference Figure 3 and Figure 8 The guide rod 121 is in the shape of a round rod, and the axis of the guide rod 121 is parallel to the axis of the plug-in section 2. The guide rod 121 is located between the slip ring 122 and the threaded section 61. The end of the guide rod 121 close to the slip ring 122 is fixed to the end surface of the slip ring 122. A stroke portion 19 is fixed to the end of the guide rod 121 close to the threaded section 61. The longitudinal section of the stroke portion 19 is in the shape of a dovetail whose width gradually increases away from the guide rod 121, and the stroke portion 19 is in the shape of an arc coaxial with the plug-in section 2 along the circumference of the plug-in section 2. A stroke groove 13 is provided along the circumference of the threaded section 61 close to the guide rod 121. The stroke portion 19 is inserted into the stroke groove 13, and when the slip ring 122 rotates relative to the plug-in section 2, it can drive the stroke portion 19 to slide in the stroke groove 13. It should be noted that the central angle of the stroke groove 13 is greater than 180° and less than 360°, so that the stroke groove 13 is in the shape of a superior arc.

[0041] Reference Figure 7 One end of the conductive sheet 10 extending out of the plug-in section 2 is bent and rolled to form a ring 14. The conductive sheet 10 is sleeved on the guide rod 121 through the ring 14, and the extension length of the guide rod 121 is greater than the extension length of the ring 14. The guide rod 121 can slide relative to the ring 14 along the axial direction parallel to the plug-in section 2.

[0042] Reference Figure 3 , Figure 7 and Figure 8 When the threaded section 61 moves from the unlocking position to the position where the limiting section 62 abuts against the first portion 41, the stroke portion 19 slides from one end of the stroke groove 13 to the other end of the stroke groove 13. During this process, the threaded section 61 rotates relative to the plug-in section 2, and pulls the guide rod 121 and the slip ring 122 to move along the axial direction of the plug-in section 2 toward the rotating sheet 4. However, through the cooperation between the stroke portion 19 and the stroke groove 13, the guide rod 121 does not rotate relative to the plug-in section 2, and the state of the conductive sheet 10 does not change.

[0043] When the threaded segment 61 moves from the position where the limiting section 62 abuts against the first part 41 to the locked position, since the thread movement direction of the threaded segment 61 does not change, the threaded segment 61 can push the guide rod 121 to rotate together during rotation, so that the guide rod 121 drives the conductive sheet 10 to move around the periphery of the plug-in segment 2, thereby increasing the portion of the conductive sheet 10 pulled out of the plug-in segment 2 and reducing the portion of the conductive sheet 10 located in the plug-in cavity 3, thereby causing the conductive sheet 10 to shrink in the plug-in cavity 3 to tighten the conductive segment of the wire.

[0044] When the threaded section 61 moves to the locking position, the conductive sheet 10 is simultaneously stretched to the conductive section of the stirrup wire. When the terminal needs to be removed from the wire, the threaded section 61 moves to the unlocking position, and the conductive sheet 10 is simultaneously recovered in the plug-in cavity 3, so that the conductive sheet 10 is loosened from the conductive section of the wire.

[0045] Reference Figure 2 and Figure 7 Furthermore, a protective ring 15 is coaxially formed on one surface of the slip ring 122 facing the threaded section 61. The outer diameter of the protective ring 15 is consistent with the outer diameter of the slip ring 122, the inner diameter of the protective ring 15 is larger than the outer diameter of the plug-in section 2, and the protective ring 15 is made of insulating material. When the threaded sleeve is in the unlocked position, the protective ring 15 covers the end of the conductive sheet 10 away from the threaded section 61; and when the threaded sleeve is in the locked position, the protective ring 15 completely covers the conductive sheet 10 located outside the plug-in section 2 to protect the conductive sheet 10.

[0046] The implementation principle of the wiring terminal of a new energy charging device in the embodiment of the present application is as follows: the threaded section 61 is threadedly moved relative to the plug section 2 to an unlocked position, and the wire can be inserted into the plug section 2. Then the threaded section 61 is threadedly moved relative to the plug section 2 to a locked position, so that the rotating piece 4 can be pressed against the insulation layer of the wire, so that the limiting teeth 5 penetrate into the insulation layer, and at the same time, the conductive piece 10 is pulled outward, so that the conductive piece 10 clamps the conductive segment of the wire.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
