[0001] This utility model relates to the field of battery pack wire technology, specifically a battery pack wire with an anti-detachment connector. Background Technology

[0002] With the rapid development of new energy technologies, battery packs, as core components of energy storage, are widely used in electric vehicles, energy storage power stations, and various portable electronic devices. They achieve efficient energy storage and stable output by connecting multiple cells in series or parallel, combined with management systems, heat dissipation structures, and wiring connections. Among these, the battery pack wiring, acting as the electrical bridge between the cells and external devices, plays a crucial role in current transmission, and its connection stability directly affects the overall performance and safety of the battery pack.

[0003] Currently, most battery pack connectors on the market use traditional plug-in connectors. These connectors are prone to loosening or even detachment during long-term use due to equipment vibration, external pulling, and other factors. This not only causes circuit interruptions but may also lead to short circuits, seriously threatening equipment safety and the lives and property of users. Therefore, there is an urgent need to develop a battery pack connector with a reliable anti-detachment structure to improve the stability and reliability of the battery pack's electrical connections. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a battery pack wire with an anti-detachment connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery pack conductor with an anti-detachment connector, comprising a conductor body, a male connector fixedly connected to the bottom end of the conductor body, lugs fixedly connected to both sides of the male connector, a pin rotatably connected to the inner side of the lugs, a second lug rotatably connected to the outer surface of the pin, a snap-fit ​​plate fixedly connected to one end of the second lug, a female connector inserted into the bottom end of the male connector, a locking groove provided on the side wall of the female connector, a circuit board fixedly connected to the bottom end of the female connector, a solder pad provided on the upper surface of the circuit board, a conductive sheet welded to the upper surface of the solder pad, a battery pack body welded to the bottom end of the conductive sheet, and a metal spring sleeved on the outer surface of the pin.

[0006] As described above, the male connector includes a terminal block located at the bottom, a guide strip is fixedly connected to the outer surface of the terminal block, and a guide groove is provided on the top of the female connector.

[0007] As described above, the wiring terminal is inserted into the interior of the female connector, and the guide strip is in clearance fit with the guide groove, with the front end of the guide strip having a chamfer.

[0008] As described above, the top of the female connector has a circular hole, and a spring is embedded in the circular hole, with the top of the spring abutting against the male connector.

[0009] As described above, one end of the metal spring abuts against the inner side of the buckle plate, and the other end of the metal spring abuts against the side wall of the male connector, and the elastic modulus of the metal spring is 150-210 GPa.

[0010] As described above, the bottom end of the buckle plate has a triangular block, which is hooked into the interior of the locking groove.

[0011] As described above, a charging port is fixedly connected to the top of the circuit board, and plastic sleeves are snapped into both ends of the battery pack body. A foot is fixedly connected to the top of the plastic sleeve, and the top of the foot is connected to the battery pack body by screws.

[0012] Compared with existing technologies, this battery pack wire with anti-detachment connector has the following advantages:

[0013] 1. When the male connector at one end of the wire body is connected to the female connector on the circuit board, the triangular block at the bottom of the buckle plate hooks into the locking groove, the spring provides an upward resisting force, and the metal spring sheet abuts against the buckle plate. The two work together to make the buckle plate tightly hook into the locking groove, which can effectively resist external forces such as vibration and prevent the connection from loosening and falling off. When separating, simply pinch the buckle plate to compress the metal spring sheet, and the triangular block will disengage from the locking groove. The spring will then push the male connector, and the male connector can be pulled out to complete the separation from the female connector. The operation is easy and effortless.

[0014] II. This utility model ensures accurate guidance and low resistance when inserting the terminal block by using the beveled front end of the guide bar and the gap between it and the guide groove; multiple batteries are connected in series in the plastic sleeve to form the battery pack body; the foot posts are used with screws to fix the circuit board, resulting in a compact and stable structure; the charging port on the top facilitates charging of the battery pack; and the conductive sheet is soldered on the pad to ensure stable and reliable circuit connection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a battery pack wire with an anti-detachment connector, including a wire body 1, a male connector 2 fixedly connected to the bottom end of the wire body 1, ear 3 fixedly connected to both sides of the male connector 2, a pin 4 rotatably connected to the inner side of the ear 3, ear 5 rotatably connected to the outer surface of the pin 4, a snap plate 6 fixedly connected to one end of the ear 5, a female connector 7 inserted into the bottom end of the male connector 2, a locking groove 8 opened on the side wall of the female connector 7, a circuit board 9 fixedly connected to the bottom end of the female connector 7, a solder pad 10 provided on the upper surface of the circuit board 9, a conductive sheet 11 welded to the upper surface of the solder pad 10, a battery pack body 12 welded to the bottom end of the conductive sheet 11, and a metal spring 13 sleeved on the outer surface of the pin 4.

[0025] like Figures 3-4 As shown, the male connector 2 includes a terminal block 21 located at the bottom, and a guide strip 22 is fixedly connected to the outer surface of the terminal block 21. The female connector 7 has a guide groove 18 on its top.

[0026] The terminal block 21 is inserted into the inside of the female connector 7, and the guide bar 22 is in clearance fit with the guide groove 18. The front end of the guide bar 22 is chamfered.

[0027] The beveled front end of the guide bar 22 provides guidance when the terminal 21 is inserted into the female connector 7, reducing resistance and deviation during insertion. This allows the terminal 21 to be more smoothly aligned with the internal space of the female connector 7. The clearance fit ensures that the guide bar 22 has a certain amount of room to move within the guide groove 18, preventing difficulty in insertion and removal due to excessive tightness. The combination of both also constrains the insertion direction of the male connector 2, ensuring that the terminal 21 is accurately inserted into the female connector 7.

[0028] like Figure 6 As shown, the top of the female connector 7 has a round hole, and a spring 14 is embedded in the round hole. The top of the spring 14 abuts against the male connector 2.

[0029] By setting the spring 14, when the male connector 2 and the female connector 7 are connected, the triangular block at the bottom of the snap plate 6 hooks into the locking groove 8. Since the spring 14 has an upward resisting force on the male connector 2, on the one hand, after the male connector 2 and the female connector 7 are connected, the spring 14 maintains a resisting force on the male connector 2, which will make the triangular block at the bottom of the snap plate 6 tightly hook into the locking groove 8, thereby preventing the male connector 2 and the female connector 7 from falling off due to vibration and other factors; on the other hand, when separating the male connector 2 and the female connector 7, once the triangular block at the bottom of the snap plate 6 is disengaged from the locking groove 8, it will immediately push the male connector 2 upward, so as to make the terminal 21 come out of the female connector 7 with ease.

[0030] like Figure 4 As shown, one end of the metal spring 13 abuts against the inner side of the buckle plate 6, and the other end of the metal spring 13 abuts against the side wall of the male connector 2, and the elastic modulus of the metal spring 13 is 150-210 GPa.

[0031] The bottom of the buckle plate 6 has a triangular block that hooks into the inside of the locking groove 8.

[0032] By pinching the buckle plate 6 to compress the metal spring 13, the triangular block at the bottom of the buckle plate 6 can be disengaged from the locking groove 8. Then, the male connector 2 can be easily pulled out to separate it from the female connector 7. After the male connector 2 and the female connector 7 are connected, the metal spring 13 can abut against the buckle plate 6 to keep the triangular block at its bottom hooked inside the locking groove 8. The elastic modulus range of the metal spring 13 can provide sufficient buckling locking force.

[0033] like Figure 2 As shown, a charging port 15 is fixedly connected to the top of the circuit board 9, and plastic sleeves 16 are snapped into both ends of the battery pack body 12. A foot post 17 is fixedly connected to the top of the plastic sleeve 16, and the top of the foot post 17 is connected to the battery pack body 12 by screws.

[0034] Multiple batteries can be secured by two sets of plastic sleeves 16. The electrodes of the multiple batteries are welded together by metal sheets, so that the multiple batteries are connected in series to form the battery pack body 12. Four feet 17 are provided on the top of the plastic sleeves 16, and screw holes are opened inside to fix the circuit board 9 with screws. The battery pack body 12 can be charged by providing a charging port 15 on the top of the circuit board 9.

[0035] Working principle: First, the male connector 2, which is fixedly connected to the bottom of the wire body 1, is inserted into the female connector 7 through the terminal block 21. The terminal block 21 is precisely inserted by utilizing the gap fit between the guide strip 22 and the top guide groove 18 of the female connector 7, as well as the oblique guide angle of the front end of the guide strip 22. After the male connector 2 is inserted, the top of the spring 14 in the top round hole of the female connector 7 abuts against the male connector 2. At the same time, the buckle plate 6 is rotated. Under the action of the metal spring piece 13, the triangular block at the bottom of the buckle plate 6 hooks into the locking groove 8 on the side wall of the female connector 7. The resisting force of the spring 14 further tightens the buckle plate 6, preventing the male connector 2 and the female connector 7 from falling off due to vibration. When it is necessary to separate the male connector 2 and the female connector 7, the buckle plate 6 is pinched to compress the metal spring piece 13, causing the triangular block at the bottom of the buckle plate 6 to disengage from the locking groove 8. The spring 14 pushes the male connector 2 upward, and the male connector 2 is easily pulled out to complete the separation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
