[0001] This utility model relates to the field of battery terminal technology, and in particular to an insulation locking device for supercapacitor battery terminals. Background Technology

[0002] Chinese patent document CN202013814U discloses an insulation locking device for supercapacitor battery terminals. The insulation locking device is set on the outside of the terminal and consists of an upper cover and a base. The upper cover and the base are fastened together as one unit. This structure ensures that the base only moves up and down when the upper cover rotates, avoiding the short circuit phenomenon caused by the simultaneous rotation of the terminal lug during the locking process in the prior art. It also has the advantages of simple structure, convenient installation and disassembly, safety and reliability, good locking effect, good insulation performance, increased contact area, and reduced contact resistance.

[0003] However, during the disassembly and assembly of the above device, the top cover rotates while the base does not, causing continuous friction between the two. Over time, this will result in material loss, not only producing material dust pollution but also causing structural instability. To address this, we propose an insulation locking device for the supercapacitor battery terminals. Utility Model Content

[0004] The purpose of this invention is to provide an insulation locking device for supercapacitor battery terminals, which can solve the problem of material and structural damage caused by friction during the disassembly and assembly of some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a supercapacitor battery terminal insulation locking device, comprising:

[0006] The supercapacitor battery has a battery terminal bolt fixedly installed on its top, a battery terminal nut threaded on the battery terminal bolt, a metal movable sleeve threaded on the battery terminal bolt, and a metal movable sleeve fitted on the outside of the metal movable sleeve.

[0007] A positioning mechanism is located between the bottom of the plastic protective sleeve and the top of the supercapacitor battery. The positioning mechanism is used to limit the rotation of the plastic protective sleeve.

[0008] The drag reduction mechanism is located between the plastic protective sleeve and the metal movable sleeve. The drag reduction mechanism includes a snap ring, a snap groove, and an annular groove. The bottom of the metal movable sleeve is integrally formed with a snap ring. The inner wall of the plastic protective sleeve is provided with a snap groove. The snap ring is located in the snap groove. The top and bottom of the snap ring and the inner top and inner bottom of the snap groove are each provided with a set of annular grooves.

[0009] Preferably, the drag reduction mechanism further includes balls, and at least two sets of balls are engaged between the top and bottom of the snap ring and the annular groove at the top and bottom of the inner side of the annular groove.

[0010] Preferably, the positioning mechanism includes positioning blocks, fixing rings, and positioning grooves. At least two sets of positioning blocks are fixedly installed at the bottom of the plastic protective sleeve, and a fixing ring is fixedly installed at the top of the supercapacitor battery. At least two sets of positioning grooves are opened at the top of the fixing ring, and each set of positioning blocks is engaged in the corresponding positioning groove.

[0011] Preferably, a metal clip is fixedly installed on the inner wall of the plastic protective sleeve. The bottom of the metal clip has a hexagonal groove with a shape corresponding to the battery terminal nut. The metal clip is engaged with the battery terminal nut through the hexagonal groove.

[0012] Preferably, an external wiring port is fixedly installed on the outer surface of the metal sleeve, and the external wiring port extends through the plastic protective sleeve to the outside of the plastic protective sleeve.

[0013] Preferably, a plastic retaining sleeve is fixedly installed on the outer surface of the metal movable sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The supercapacitor battery terminal insulation locking device adds a ball between the plastic protective sleeve and the metal movable sleeve through a drag reduction mechanism, which changes the existing sliding friction to rolling friction, greatly reducing the loss caused by friction. This solves the problem that in some existing devices, the top cover rotates while the base does not rotate during disassembly and assembly, which causes continuous friction between the two and will cause material loss in the long run. This not only generates material dust pollution, but also causes structural instability, thus improving the practicality of the device.

[0017] (2) The supercapacitor battery terminal insulation locking device, through the positioning mechanism, can prevent the plastic protective sleeve from being rotated by external force during use, avoid causing the battery terminal nut to rotate and loosen, ensure the effectiveness of the device, and facilitate the promotion and use of the device.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a supercapacitor battery terminal insulation locking device, including a supercapacitor battery 1, a positioning mechanism 7, and a drag reduction mechanism 6. A battery terminal bolt 2 is fixedly installed on the top of the supercapacitor battery 1. A battery terminal nut 3 is threaded onto the battery terminal bolt 2. A metal movable sleeve 5 is threaded onto the battery terminal bolt 2. A metal movable sleeve 5 is fitted onto the outer side of the metal movable sleeve 5. The positioning mechanism 7 is located between the bottom of a plastic protective sleeve 4 and the top of the supercapacitor battery 1. The positioning mechanism 7 is used to lock the plastic protective sleeve 4 in place. The protective sleeve 4 is rotated and limited. A metal clip 8 is fixedly installed on the inner wall of the plastic protective sleeve 4. The bottom of the metal clip 8 has a hexagonal groove 9 with a shape corresponding to the battery terminal nut 3. The metal clip 8 is snapped onto the battery terminal nut 3 through the hexagonal groove 9. An external wiring port 10 is fixedly installed on the outer surface of the metal clip 8. The external wiring port 10 extends through the plastic protective sleeve 4 and out of the plastic protective sleeve 4. A plastic fixing sleeve 11 is fixedly installed on the outer surface of the metal movable sleeve 5. At least two sets of anti-slip grooves 12 are opened on the outer surface of the plastic fixing sleeve 11.

[0027] The drag reduction mechanism 6 is disposed between the plastic protective sleeve 4 and the metal movable sleeve 5. The drag reduction mechanism 6 includes a snap ring 61, a snap groove 62 and an annular groove 63. The bottom of the metal movable sleeve 5 is integrally formed with a snap ring 61. The inner wall of the plastic protective sleeve 4 is provided with a snap groove 62. The snap ring 61 is disposed in the snap groove 62. A set of annular grooves 63 are provided at the top and bottom of the snap ring 61 and at the top and bottom of the inner side of the snap groove 62.

[0028] The drag reduction mechanism 6 also includes balls 64. At least two sets of balls 64 are engaged between the top and bottom of the snap ring 61 and the inner top and bottom of the annular groove 63. By adding balls 64 between the plastic protective sleeve 4 and the metal movable sleeve 5 during relative rotation through the drag reduction mechanism 6, the existing sliding friction is changed to rolling friction, which greatly reduces the loss caused by friction. This solves the problem that in some existing devices, during disassembly and assembly, the top cover rotates while the base does not rotate, causing continuous friction between the two, which will cause material loss in the long run, not only producing material dust pollution, but also causing structural instability. This improves the practicality of the device.
