Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a structure for preventing loose wiring and a battery. Background Technology

[0002] A battery is a device that directly converts chemical energy into electrical energy; its working principle is based on an electrochemical reaction. When using a battery, it is usually necessary to limit the cable connectors to prevent the cable from being pulled, which could cause the connector to loosen and affect the normal power supply.

[0003] CN204927406U discloses an anti-loosening lead-acid battery terminal mounting structure, which includes a terminal with an axial mounting screw hole, a connecting piece with a through screw hole, and a fastening bolt. The edge of the terminal's wiring mounting end face is provided with a groove, and the connecting piece is provided with a protruding locking key that mates with the groove, which avoids the rotational misalignment between the connecting piece and the terminal, thereby further ensuring the stability of the fastening bolt and keeping the connecting piece and the terminal in good contact at all times.

[0004] This patent uses fastening bolts to fix the cable connectors to the terminals. However, when installing, debugging, repairing, or replacing the battery, the cable needs to be connected frequently, which requires operators to frequently tighten or loosen the fastening bolts, making the operation relatively inconvenient. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a structure to prevent loose wiring. This solves the technical problem that in the prior art, the cable connector is fixed to the terminal block by fastening bolts. However, when installing, debugging, or repairing or replacing the battery, the cable needs to be connected frequently, which requires the operator to frequently tighten or loosen the fastening bolts, making the operation relatively inconvenient.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides an anti-loosening structure for limiting the loosening of connectors inserted into the wiring port of the main structure, including:

[0008] Mounting section, used for mounting to the main structure;

[0009] An anti-loosening part is movably installed on the mounting part and has an anti-loosening position and a loosening position located during its movement stroke. When the anti-loosening part is in the anti-loosening position, it is located on the movement path of the connector disengaging from the wiring port, thereby restricting the connector inserted into the wiring port from disengaging. When the anti-loosening part is in the loosening position, it is offset from the movement path of the connector disengaging from the wiring port.

[0010] An elastic element connects the mounting portion and the anti-loosening portion, and is used to drive the anti-loosening portion to return from the loosened position to the anti-loosening position.

[0011] In some embodiments, the direction of movement of the anti-loosening part is perpendicular to the insertion direction of the connector.

[0012] In some embodiments, the anti-loosening part includes an anti-loosening sleeve, which is slidably connected to the mounting part along the insertion direction perpendicular to the connector. The anti-loosening sleeve has an opening. When the anti-loosening sleeve is in the anti-loosening position, it slides onto the movement path of the connector disengaging from the terminal, and the anti-loosening sleeve avoids the cable of the connector through the opening. When it is in the loosening position, the anti-loosening sleeve slides to be offset from the movement path of the connector disengaging from the terminal.

[0013] In some embodiments, the anti-loosening part further includes an anti-loosening arm, which is slidably connected to the mounting part along the insertion direction perpendicular to the connector, and the anti-loosening sleeve is connected to the anti-loosening arm and slidably connected to the mounting part via the anti-loosening arm.

[0014] In some embodiments, the mounting portion is provided with a mounting channel, the axis of which is perpendicular to the insertion direction of the connector;

[0015] The anti-loosening arm is slidably positioned in the installation channel.

[0016] In some embodiments, the anti-loosening part further includes a handle, which is connected at an angle to the anti-loosening arm and is located on both sides of the mounting channel axially with the wiring port.

[0017] In some embodiments, the handle includes a connecting section and two gripping sections, the connecting section being connected to the anti-loosening arm at an angle, and the two gripping sections being respectively connected to both ends of the connecting section;

[0018] Two elastic elements are provided, and the two elastic elements are respectively connected to the mounting part and the two gripping sections.

[0019] Secondly, this solution also provides a battery that includes the anti-loosening wiring structure described in any of the above claims.

[0020] In some embodiments, the battery further includes a battery cell, a housing, and terminals. The battery cell is located inside the housing, the housing has the terminals, and the terminals are located inside the terminals and electrically connected to the battery cell.

[0021] The mounting part is installed on the outer wall of the housing and corresponds to the wiring port.

[0022] In some embodiments, multiple wiring ports and multiple wiring terminals are provided, and the multiple wiring terminals are located within the multiple wiring ports;

[0023] The anti-loosening structure is provided in multiple parts, wherein each of the multiple installation parts corresponds to a multiple of the wiring ports.

[0024] Compared with existing technologies, the anti-loosening structure provided by this utility model has an mounting part installed on the battery cell. Since the anti-loosening part is movably mounted on the mounting part and can switch between an anti-loosening position and a loosening position, when a cable needs to be connected, an external force is first applied to move the anti-loosening part from the anti-loosening position to the loosening position to avoid the connector, allowing the connector to be smoothly inserted into the battery cell's wiring port. The elastic element is in a deformed state at this time. After the connector is inserted, the anti-loosening part is released, and under the elastic force of the elastic element, it automatically returns from the loosening position to the anti-loosening position, preventing the connector from detaching from the wiring port and avoiding accidental cable disconnection. Therefore, this solution only requires pulling the anti-loosening part to remove the connector, and after releasing the anti-loosening part, it automatically returns to the position limiting the connector, making the operation of connecting cables relatively convenient when installing, debugging, or repairing / replacing the battery.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] To address the technical problem of existing technologies that use bolts to fix cable connectors to terminals, which is inconvenient during battery installation, debugging, or repair, requiring frequent cable connections and bolt tightening / loosening, this invention provides an anti-loosening structure. The connector can be pulled away simply by pulling the anti-loosening part, and after release, the anti-loosening part automatically returns to its limiting position on the connector, making cable connection during battery installation, debugging, or repair much more convenient.

[0035] It should be noted that the anti-loosening wiring structure described in this utility model is used in, but not limited to, batteries. For ease of explanation, this utility model only uses the application of the anti-loosening wiring structure in batteries as an example. The principle of the anti-loosening wiring structure in other types of equipment is essentially the same as that in batteries, and will not be described in detail here.

[0036] Please see Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the anti-loosening structure in one embodiment of the present invention. The anti-loosening structure is used to restrict the loosening of the connector inserted into the wiring port of the main structure. It includes a mounting part 1, an anti-loosening part 2, and an elastic member 3. The mounting part 1 is used to be mounted on the main structure 4 having a wiring port 42a. The anti-loosening part 2 is movably mounted on the mounting part 1 and has an anti-loosening position and a loosening position in its active stroke. When the anti-loosening part 2 is in the anti-loosening position, the anti-loosening part 2 is located on the active path of the connector leaving the wiring port 42a, which is used to restrict the connector inserted into the wiring port 42a from detaching. When it is in the loosening position, the anti-loosening part 2 is offset from the active path of the connector leaving the wiring port 42a to release the connector. The elastic member 3 connects the mounting part 1 and the anti-loosening part 2 and is used to drive the anti-loosening part 2 to return from the loosening position to the anti-loosening position.

[0037] In the anti-loosening structure provided by this utility model, the mounting part 1 is installed on the battery cell 41. Since the anti-loosening part 2 is movably mounted on the mounting part 1 and can switch between the anti-loosening position and the loosening position, when a cable needs to be connected, an external force is applied to move the anti-loosening part 2 from the anti-loosening position to the loosening position to avoid the connector, allowing the connector to be smoothly inserted into the wiring port 42a of the battery cell 41. At this time, the elastic member 3 is in a deformed state. After the connector is connected, the anti-loosening part 2 is released, and under the elastic force of the elastic member 3, the anti-loosening part 2 automatically returns from the loosening position to the anti-loosening position, thus preventing the connector from detaching from the wiring port 42a and avoiding accidental cable disconnection. Therefore, this solution only requires pulling the anti-loosening part 2 to remove the connector, and after releasing the anti-loosening part 2, it can automatically return to the position limiting the connector, making the operation of connecting cables relatively convenient when installing, debugging, or repairing / replacing the battery. It should be understood that the aforementioned main structure 4 refers to the main structure 4 of the battery.

[0038] It should be noted that, in one embodiment, one end of the anti-loosening part 2 is rotatably mounted to the mounting part 1. When the rotating end of the anti-loosening part 2 rotates, it drives the other end to stop and move away from the connector, thereby limiting the position of the connector. In another embodiment, the anti-loosening part 2 is directly connected to the mounting part 1 through the elastic member 3. In this case, the anti-loosening part 2 can move in any direction. In this embodiment, when the elastic member 3 is in its natural state, the end of the anti-loosening part 2 is located on the disengagement path of the connector.

[0039] In another embodiment, the movement direction of the anti-loosening part 2 is perpendicular to the insertion direction of the connector. Specifically, in this design, the mounting part 1 has a mounting end 11 spaced apart from the main structure 4, and the mounting end 11 and the wiring port 42a are located on the same side of the main structure 4; the anti-loosening part 2 is movably mounted on the mounting end 11, and its movement direction is parallel to the plane where the port of the wiring port 42a is located. When it is in the anti-loosening position, it blocks the side of the connector away from the wiring port 42a, and when it is in the loosened position, it disengages from the connector.

[0040] In this embodiment, the mounting part 1 is provided with a mounting end 11 spaced apart from the battery cell 41, and the mounting end 11 and the wiring port 42a are placed on the same side of the battery cell 41. At the same time, the anti-loosening part 2 is provided on the mounting end 11 and moves in a direction parallel to the wiring port 42a. In this way, while the anti-loosening part 2 limits the plug, the overall structure is relatively compact, so as to realize the miniaturization of the anti-wiring loosening structure.

[0041] It should be noted that the specific form of the mounting part 1 is not limited, and it can be set as a mounting plate, a mounting base, or a mounting platform. Specifically, in this solution, the mounting part 1 is set as a mounting plate. In addition, the specific form of the anti-loosening part 2 is not limited, and it can be set as an anti-loosening arm 21, an anti-loosening plate, and an anti-loosening seat.

[0042] In one embodiment, the anti-loosening part 2 includes an anti-loosening sleeve 22, which is slidably connected to the mounting part 1 along the insertion direction of the vertical connector. The anti-loosening sleeve 22 has an opening. When the anti-loosening sleeve 22 is in the anti-loosening position, it slides onto the movement path of the connector disengaging from the wiring port 42a, and the anti-loosening sleeve 22 avoids the cable of the connector through the opening. When it is in the loosened position, the anti-loosening sleeve 22 slides to the point of being off-center from the movement path of the connector disengaging from the wiring port 42a.

[0043] In this embodiment, when the anti-loosening arm 21 moves to stop the plug, the anti-loosening sleeve 22 is fitted around the cable periphery of the plug, and at the same time stops the plug, restricting the plug from leaving the wiring port 42a, thereby improving the stability of the plug during installation.

[0044] In one embodiment, the anti-loosening part 2 further includes an anti-loosening arm 21, which is slidably connected to the mounting part 1 along the insertion direction of the vertical connector. The anti-loosening sleeve 22 is connected to the anti-loosening arm 21 and is slidably connected to the mounting part 1 via the anti-loosening arm.

[0045] In this embodiment, when the anti-loosening arm 21 moves to the side of the connector away from the wiring port 42a, it cooperates with the anti-loosening sleeve 22 to block the connector, thereby limiting the connector from detaching from the wiring port 42a and ensuring the stability of the connector installation. When it is necessary to disassemble the connector, the anti-loosening part 2 can be moved to the position where it is detached from the connector. The operation is simple and convenient.

[0046] In one embodiment, the mounting part 1 is provided with a mounting channel 11a, the axis of which is perpendicular to the insertion direction of the connector; the anti-loosening arm 21 is slidably disposed in the mounting channel 11a. Specifically, in this solution, the mounting channel 11a is located at the mounting end 11, and the axis of the mounting channel 11a is parallel to the plane where the port of the wiring port 42a is located.

[0047] In this embodiment, the anti-loosening arm 21 is movably inserted into the installation channel 11a of the installation end 11. The installation channel 11a guides the anti-loosening arm 21, so that the anti-loosening arm 21 can effectively block the plug on the side away from the wiring port 42a.

[0048] In one embodiment, the anti-loosening part 2 further includes a handle 23, which is connected at an angle to the anti-loosening arm 21 and is located on both sides of the wiring port 42a along the axial direction of the mounting channel 11a.

[0049] In this embodiment, a handle 23 is connected to the upper end of the anti-loosening arm 21. On the one hand, it is convenient for the operator to lift the anti-loosening arm 21 through the handle 23, thus improving convenience. On the other hand, it can effectively prevent the anti-loosening arm 21 from completely detaching through the lower side of the installation channel 11a.

[0050] In one embodiment, the handle 23 includes a connecting section 231 and two gripping sections 232. The connecting section 231 is connected to the anti-loosening arm 21 at an angle, and the two gripping sections 232 are respectively connected to the two ends of the connecting section 231. Two elastic members 3 are provided, and the two elastic members 3 are respectively connected to the mounting part 1 and the two gripping sections 232.

[0051] In this embodiment, the handle 23 is configured with two symmetrically arranged gripping sections 232, and elastic elements 3 are respectively provided between the gripping sections 232 and the mounting end 11 to improve the stability of the anti-loosening arm 21 when it moves up and down. It should be noted that the elastic element 3 is one of a disc spring, a gas spring, and a coil spring. Specifically, in this solution, the elastic element 3 is a coil spring.

[0052] In addition, please see Figures 4 to 6 This utility model also provides a battery, which includes the aforementioned anti-loosening wiring structure. It should be noted that the detailed structure of the anti-loosening wiring structure can be found in the embodiments described above, and will not be repeated here. Since the battery of this utility model uses the aforementioned anti-loosening wiring structure, the embodiments of the battery of this utility model include all the technical solutions of all embodiments of the aforementioned anti-loosening wiring structure, and the achieved technical effects are completely the same, and will not be repeated here.

[0053] In one embodiment, the battery further includes a cell 41, a housing 42, and a terminal block. The cell 41 is located inside the housing 42. The housing 42 is provided with a terminal block 42a. The terminal block is located inside the terminal block 42a and is electrically connected to the cell 41. The mounting part 1 is mounted on the outer wall of the housing 42 and corresponds to the terminal block 42a.

[0054] In this embodiment, the battery cell 41 and the housing 42 together constitute the main structure 4. The housing 42 protects the battery cell 41, and a wiring port 42a is provided on the housing 42 for the insertion of a connector. Specifically, in this design, a protective pad 45 is provided at each of the four corners of the interior of the housing 42 at right angles. The protective pad 45 is located between the battery cell 41 and the inner wall of the housing 42 to further protect the battery cell 41.

[0055] In one embodiment, the housing 42 includes a cover 44 and a bottom shell 43, the cover 44 and the bottom shell 43 being detachably connected and together forming a cavity in which the power supply core 41 is placed.

[0056] In this design, the housing 42 is configured with a detachable cover 44 and a bottom shell 43 to facilitate inspection and maintenance of the internal structure by operators. Specifically, the cover 44 and the bottom shell 43 are each provided with a connecting plate 46, which has through holes for fixing with connecting bolts and nuts. In addition, a sealing gasket is provided between the cover 44 and the bottom shell 43, and a fixing plate 48 with holes is provided on the bottom of the outer wall of the bottom shell 43.

[0057] In one embodiment, multiple wiring ports 42a and multiple wiring terminals are provided, and multiple wiring terminals are located in multiple wiring ports 42a respectively; multiple anti-loosening structures are provided, wherein multiple mounting parts 1 correspond to multiple wiring ports 42a respectively.

[0058] In this embodiment, multiple wiring ports 42a are provided on the housing 42, and multiple anti-loosening structures are provided for the multiple wiring ports 42a, so that operators can flexibly select the wiring ports 42a, which has good practicality.

[0059] It should be noted that in this design, the housing 42 includes a base layer 421, an insulation layer 422 is provided on the outer side of the base layer 421, a waterproof layer 423 is provided on the outer side of the insulation layer 422, and a protective layer 424 is provided on the outer side of the waterproof layer 423, further improving the safety of the internal battery cell 41. In one embodiment, the base layer 421 is made of high-temperature resistant plastic, the insulation layer 422 is made of insulation cotton, the waterproof layer 423 is made of waterproof plastic, and the protective layer 424 is made of a steel frame.

[0060] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:

[0061] In use, the battery cell 41 is placed inside the bottom shell 43, and then the cover 44 is placed on top. The cover 44 is fixed to the bottom shell 43 by the cooperation of the connecting plate 46 on the bottom shell 43 and by the connecting bolts and nuts. The sealing gasket improves the sealing at the connection between the bottom shell 43 and the cover 44. In addition, during use, by pulling the handle 23 upward with a large force, the anti-loosening arm 21 and the anti-loosening sleeve 22 are moved upward, causing the two elastic elements 3 to extend. The cable connector is then inserted into the terminal 42a. Then, the handle 23 is released, causing it to move downward under the action of the two elastic elements 3. This allows the anti-loosening sleeve 22 to be placed on the surface of the cable. The anti-loosening sleeve 22 and the anti-loosening arm 21 stop the connector, limiting its position and preventing the cable from being pulled, which could cause the connection between the connector and the terminal 42a to loosen, thus ensuring normal power supply.

[0062] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
