Description

Technical Field

[0001] The utility model relates to the technical field of battery wiring, in particular to a heat shrink device for a heat shrink tubing of a battery wiring. Background Art

[0002] The main purpose of heat shrink tubing for battery cable wraps is to provide additional protection and insulation to prevent the steel strip from coming into contact with other components or moisture, corrosion, and other substances in the environment, thereby reducing damage to the steel strip caused by external factors. In addition, the heat shrink tubing will shrink when heated to form a tightly fitting outer layer, which helps to better fix and protect the steel strip and prevent it from loosening or shifting during use. Heat shrink tubing is usually made of insulating material and can provide a certain degree of insulation performance to prevent current leakage or short circuit on the steel strip. It is very important for the safety and stability of the battery pack. Therefore, whether to use heat shrink tubing depends on the design and requirements of the battery pack, as well as the specific application environment.

[0018] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," and "downwardly" are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Numerical designations such as "first" and "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0019] Embodiment: A heat shrink device for heat shrink tubing of battery wiring, such as Figure 1-Figure 3 As shown, it includes a handle Ⅰ1, a splint Ⅰ2, a hinged plate 4, a handle Ⅱ5, a splint Ⅱ7 and a heating tube. The left part of the handle Ⅰ1 is fixedly connected to the splint Ⅰ2, the middle part of the handle Ⅰ1 is hinged to the hinged plate 4 through a hinge structure, and the end of the hinged plate 4 not hinged to the handle Ⅰ1 is hinged to the handle Ⅱ5 through a hinge structure. The handle Ⅰ1 and the handle Ⅱ5 are both provided with anti-skid grooves for preventing slipping. The left part of the handle Ⅱ5 is fixedly connected to the splint Ⅱ7. The splint Ⅰ2 and the splint Ⅱ7 are connected by a rotating shaft, and a rotating shaft damper is provided on the rotating shaft. In addition, the splint I2 and the splint II7 are in contact with each other in the initial state, and a heating tube is provided between the splint I2 and the splint II7. The heating tube includes a heating tube plate I3, a heating tube plate II8, a one-way air outlet valve 81 and a heating component. The middle part of the splint I2 is penetrated by the heating tube plate I3, and the middle part of the splint II7 is penetrated by the heating tube plate II8. The heating tube plate I3 and the heating tube plate II8 are in contact with each other in the initial state, a one-way air outlet valve 81 is penetrated by the front left part of the heating tube plate II8, and a heating component is provided on the heating tube plate II8.

[0020] like Figure 1-Figure 3 As shown, the heating assembly includes a mounting tube 9, an electric heating tube 91 and an air supply mechanism 92. The mounting tube 9 is fixedly connected to the front right side of the heating tube plate II 8. The electric heating tube 91 is installed in the mounting tube 9 by bolts. The air supply mechanism 92 is provided in the mounting tube 9, and the air supply mechanism 92 is located above the electric heating tube 91.

[0021] like Figure 1-Figure 3As shown, it also includes a tension spring 6, a filter screen 93, and a rubber curtain 10. Between the splint Ⅰ2 and the handle Ⅱ5, a tension spring 6 is connected through a spring seat to facilitate flexible operation of the device; a filter screen 93 for filtering dust and impurities is clamped on the mounting cylinder 9, and the filter screen 93 can be removed and replaced; the front and rear sides of the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8 are connected to the rubber curtain 10, and the rubber curtain 10 is made of a soft and high-temperature resistant material.

[0022] When the device is to be used, first, the operator holds the grip Ⅰ1 and grip Ⅱ5 of the device in one hand, and squeezes the two toward each other to make them approach each other. At this time, the hinged plate 4 will rotate together and slowly approach parallelism, and the tension spring 6 will be compressed. When the grip Ⅰ1 and grip Ⅱ5 approach each other, the splint Ⅰ2 will rotate on the splint Ⅱ7 with the components installed on it. When the splint Ⅰ2 rotates, a gap will appear between the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8, and the gap will increase as the grip Ⅰ1 and grip Ⅱ5 approach each other. When the handle Ⅰ1 and the grip Ⅱ5 cannot be moved any closer, the battery line with the heat shrink tube is placed between the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8. The operator stops applying force to the grip Ⅰ1 and the grip Ⅱ5, and with the help of the reverse action of the tension spring 6, the grip Ⅰ1 and the grip Ⅱ5 and the parts connected to the two will be reset. After the reset is completed, the battery line with the heat shrink tube is just located between the two heating cylinder plates, and the rubber curtain 10 is close to the battery line, and they fit tightly with each other without gaps, thereby sealing the distance between the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8, thereby improving the heating efficiency and effect, and driving the electric The heat pipe 91, after being heated to the required temperature, drives the air supply mechanism 92, which draws the air outside the installation cylinder 9 into the installation cylinder 9 through the filter 93, and blows the air that has filtered out dust and impurities to the electric heating pipe 91. The wind after passing through the electric heating pipe 91 will become hot air and blow evenly to the space between the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8. When the hot air contacts the heat shrink tube, the heat shrink tube will shrink and deform, and tightly wrap the battery line, thereby completing the heat shrink work of the heat shrink tube on the battery line. The spacing between the heating cylinder plate Ⅰ3 and the heating cylinder plate Ⅱ8 is wide, and the heat shrink tube can be used to heat the battery line. The flexibility of the rubber curtain 10 allows it to fit well with battery cables of any size or shape, greatly improving the versatility and usability of the device. After completing the heat shrinking work on the battery cables, the operator squeezes the handle Ⅰ1 and the handle Ⅱ5 between them to bring them closer to each other, thereby increasing the gap between the heating tube plate Ⅰ3 and the heating tube plate Ⅱ8, and then takes out the battery cables after the heat shrinking of the heat shrink tube. When the next battery cable is to be heat shrunk with the heat shrink tube, the above steps are repeated. After all the work is completed, the electric heating tube 91 and the air supply mechanism 92 are turned off.

[0023] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
