Description

Technical Field

[0001] This utility model relates to the field of charging pile gun wire technology, specifically a quick installation and disassembly structure for charging pile gun wires. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into public charging piles and private charging piles, and in terms of charging methods, they are divided into AC charging piles and DC charging piles. They charge vehicles by connecting to the power grid. The charging gun cable is the cable connecting the charging pile and the electric vehicle, mainly used to transmit power and signals to realize the charging function. It charges the vehicle battery with high-voltage current. Different power charging piles correspond to different current specifications. It includes control leads used to detect the connection status of the charging gun and adjust charging parameters. It usually adopts a five-wire design, such as live wire, neutral wire, ground wire, CP signal wire, and CC confirmation wire. Some models may simplify the design and reduce the CC wire.

[0003] When installing a common charging station cable, you first need to open the charging station cover, insert the cable through the wiring inlet on one side of the charging station, connect the cable to the corresponding terminal block on the charging station, tighten the screws to ensure there is no looseness, and then use the gland to lock the cable body. Finally, seal the cable inlet with a waterproof connector to prevent rainwater from seeping in.

[0004] During the installation of the aforementioned charging pile gun wires, the wiring inside the charging pile is not fixed by any means; the terminal part of the pile body is only fixed by tightening screws. The gun wires inside the pile are prone to shaking. At the same time, after the charging cabinet is installed on the gland, it is very difficult to tighten the tightening head with an adjustable wrench due to the narrow space inside the pile. This results in a long replacement time during installation and disassembly, and the disassembly is difficult during installation and subsequent maintenance. Therefore, we propose a quick installation and disassembly structure for charging pile gun wires. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this utility model is to provide a quick installation and disassembly structure for charging pile gun wires, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation and disassembly structure for charging pile charging cables, comprising a mounting plate frame, a charging cable clamp threadedly fixed to the inner wall of the mounting plate frame, the mounting plate frame including a charging pile connection port, a quick-release plate for the charging cable attached to one side of the outer wall of the charging pile connection port, bolts fixed around the inner wall of the quick-release plate, a cable guide plate fixed at the center of the quick-release plate, and nut slots fixed on both sides of the inner wall of the cable guide plate, a gland nut fitted at the center of the cable guide plate, a through hole at the center of the gland nut, a gland core threadedly fitted at the other end of the gland nut that passes through the outer wall of the quick-release plate, the inner wall of the gland core tightly attached to the outer wall of the quick-release plate, and a gland clamping head aligned on one side of the outer wall of the gland core, an internal threaded groove formed around the inner wall of the gland clamping head, and an inner rubber ring embedded at one end of the internal threaded groove.

[0008] Furthermore, the quick-release plate for the charging cable is threadedly connected to the charging pile terminal via bolts around its inner wall, and the quick-release plate for the charging cable is integrally fixed with the cable tray and the nut slot.

[0009] Furthermore, the gland nut is tightened and fixed to the quick-release plate of the gun wire by the gland nut core, and the two sides of the gland nut engage with the nut slot.

[0010] Furthermore, the threading hole extends along the center of the gland nut, and the center of the threading hole is aligned with the center of the wire clamp.

[0011] Furthermore, the gland clamping head is threadedly connected to the end of the gland head nut via an internal thread groove, and the inner rubber ring is circumferentially embedded along the inner wall of one end of the gland clamping head.

[0012] Furthermore, the gun wire clamp includes an upper clamp frame, with mounting brackets fixed at both ends of the upper clamp frame. A threaded fastener is threaded through the center thread of the mounting bracket, and a mounting plate is fixed at the end of the mounting bracket. The mounting plate is attached to the middle of both sides of the inner wall of the gun wire quick-release plate, and a lower clamp frame is attached to the bottom surface of the upper clamp frame.

[0013] Furthermore, the upper hoop is detachable via the mounting plates on both sides and the inner wall of the quick-release plate for the gun wire, and the upper hoop is fixed to the lower hoop via threaded fasteners.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The charging gun cable can be installed at the charging port of the charging station via a quick-release plate. It is secured with the gland nut in the center of the quick-release plate and the gland core. The gland nut can be tightened by the gland clamping head at the end. This quick-release plate design allows the gland clamping head to be locked in advance offline, avoiding the problem of limited space after the gland is installed in the charging cabinet, where the adjustable wrench cannot be accessed to tighten it. When replacing the charging gun cable, only the four bolts of the quick-release plate, the screws of the charging gun clamp, and the charging gun terminal need to be removed to remove the charging gun cable, which greatly shortens the replacement time and reduces the difficulty.

[0016] The charging station's charging cable has a cable clamp fixed to the inner wall of the quick-release plate by screws. It can be used with the upper and lower clamps to reinforce the inserted cable. It is also clamped and fixed with threaded fasteners. The cable fixing uses both gland heads and clamps. The inner diameter of the upper and lower clamps is smaller than the diameter of the cable, thus ensuring that the cable inside the station is fixed and does not shake, improving the stability of installation and use.

[0025] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This utility model provides, for example Figure 1-4 The diagram illustrates a quick-installation and disassembly structure for a charging pile charging cable, comprising a mounting frame 1. A cable clamp 2 is threadedly fixed to the inner wall of the mounting frame 1. The mounting frame 1 includes a charging pile connection port 101. A quick-release cable plate 102 is attached to one side of the outer wall of the charging pile connection port 101. Bolts 103 are fixed around the inner wall of the quick-release cable plate 102. A cable guide 104 is fixed to the center of the quick-release cable plate 102, and nut slots 105 are fixed to both sides of the inner wall of the cable guide 104. A cable guide 104 is sleeved at the center of the cable guide 104. There is a gland nut 106, with a wire hole 107 in the center of the gland nut 106. The other end of the gland nut 106, which is inserted through the outer wall of the quick release plate 102, is threaded with a gland core 108. The inner wall of the gland core 108 is in close contact with the outer wall of the quick release plate 102, and a gland clamping head 109 is aligned with one side of the outer wall of the gland core 108. The inner wall of the gland clamping head 109 is provided with an internal thread groove 110 around its perimeter, and an inner rubber ring 111 is embedded at one end of the internal thread groove 110.

[0028] To provide convenience during the installation and removal of this charging station's charging cable, such as Figure 1-3As shown, the charging gun cable can be installed at the charging port 101 of the charging pile via the quick-release plate 102. It is fixed with the gland nut 106 in the center of the quick-release plate 102 and the gland core 108. At the same time, the gland nut 106 can tighten the threaded gun cable through the gland clamping head 109 at the end. The design of this quick-release plate 102 allows the gland clamping head 109 to be locked in advance offline, avoiding the problem of the space being too small after the gland is installed in the charging cabinet, making it impossible for the adjustable wrench to enter and tighten. When replacing the charging gun cable, only the four bolts 103 of the quick-release plate 102, the screws of the gun cable clamp 2, and the charging gun terminal need to be removed to remove the charging gun cable, which greatly shortens the replacement time and reduces the difficulty.

[0029] like Figure 4 As shown, the gun wire clamp 2 includes an upper clamp 201, with mounting brackets 202 fixed at both ends of the upper clamp 201. A threaded fastener 203 is threaded through the center of the mounting bracket 202, and a mounting plate 204 is fixed at the end of the mounting bracket 202. The mounting plate 204 is attached to the middle of both sides of the inner wall of the gun wire quick release plate 102, and a lower clamp 205 is attached to the bottom surface of the upper clamp 201.

[0030] To enhance the reinforcement of the gun wire installation, such as Figure 4 As shown, the charging station's charging gun cable has a charging gun cable clamp 2 fixed to the inner wall of the charging gun cable quick-release plate 102 by screws. It can work with the upper clamp 201 and the lower clamp 205 to reinforce the inserted charging gun cable. It is also clamped and fixed with the threaded fastener 203. The charging gun cable is fixed using both gland heads and clamps. The inner diameter of the upper clamp 201 and the lower clamp 205 is smaller than the diameter of the charging gun cable, thereby ensuring that the charging gun cable inside the station is fixed and does not shake, thus improving the stability of installation and use.

[0031] In summary, when using this charging station cable, the user first inserts the gland nut 106 into the cable guide 104 inside the cable quick-release plate 102. Then, the user manually pre-tightens the gland nut core 108 and gland clamping head 109 on the outside of the cable quick-release plate 102. At this time, the inside of the gland nut 106 abuts against the nut slots 105 on both sides of the cable guide 104, maintaining the stability of the pre-tightening on the outside. Then, the cable is inserted into the center of the gland nut 106. Inside the wire hole 107, use an adjustable wrench to clamp the main core 108 of the gland head and the gland clamping head 109, and tighten them. After the wire is inserted, it passes through the inner diameter of the upper clamp 201 and the lower clamp 205. Tighten the threaded fasteners 203 on both sides of the upper clamp 201 and the lower clamp 205 by rotating. Finally, align the quick-release plate 102 of the wire with the charging pile terminal 101, and tighten the bolt caps of the four sets of bolts 103 to complete the installation.
