Description

Technical Field

[0001] This utility model provides a quick-change device for the connection port of a charging connector, belonging to the field of charging connector technology. Background Technology

[0002] In today's era of rapid technological development, devices and equipment that can be used by charging have become an indispensable part of people's lives and work.

[0003] As devices are used in increasingly diverse scenarios, charging connectors operate in various complex environments. Environments with high levels of wind, sand, and dust pose a serious threat of contamination to the connection ports of charging connectors. This is especially true for ports with multiple different transmission protocols; unused ports, lacking connecting cables, are more susceptible to corrosion from wind, sand, and dust. Existing technologies can protect unused ports with protective devices, but when a connection port needs to be replaced, the connecting cable must be unplugged. This unplugging process allows wind, sand, and dust to contaminate the port again. Furthermore, opening the protective device is not only cumbersome but also introduces a momentary contamination of the port by wind and dust. To address these issues, a quick-change device for charging connector connection ports is needed. This device should not only allow for rapid and efficient port replacement but also ensure that all connection ports are protected from wind, sand, and dust corrosion. Utility Model Content

[0004] The technical problem this invention aims to solve is that, for ports with multiple different transmission protocols, it is inconvenient to quickly change the connection port while ensuring that the connection port is not corroded by wind, sand, or dust.

[0005] To solve the above problems, the proposed technical solution is as follows: a quick-change device for the connection port of a charging connector, including a charging head with prongs, and a connecting wire connected to the charging head circuit; further comprising:

[0006] The device includes a sealing plate and a fixing cylinder. The charging head has several circumferentially distributed connection ports. The sealing plate is rotatably connected to the charging head, and all connection ports are located inside the sealing plate. A fixing cylinder corresponding to the connection port is fixedly connected to the sealing plate, and an elastic sliding component is provided on the fixing cylinder. A contact that passes through the sealing plate and is inserted into the connection port is fixedly connected to the end of the elastic sliding component, and the contact is connected to the connecting wire circuit.

[0007] As an improvement, the elastic sliding assembly includes a sliding rod, a limiting block, and a spring. The sliding rod is slidably disposed inside the fixed cylinder, and the limiting block is fixedly sleeved on the sliding rod. The spring is sleeved on the sliding rod, and the positions of the spring and the limiting block correspond.

[0008] As an improvement, the contact is fixedly connected to the lower end of the sliding rod. Both the sliding rod and the limiting block are insulators, and the connecting wire passes through the inside of the sliding rod and is connected to the contact circuit.

[0009] As an improvement, the spring is designed to allow for compression; an operating block is provided above the fixed cylinder and is fixedly connected to the sliding rod.

[0010] As an improvement, the connection port is provided with six ports of the same shape but with different transmission protocols, and the six connection ports are evenly distributed in a circumferential shape on the charging head.

[0011] As an improvement, the outer wall of the charging head is fixedly provided with six indicator rods corresponding to the connection ports.

[0012] The beneficial effects of this utility model are:

[0013] The sealing plate is rotatably connected to the charging head, and all connection ports are located within the sealing plate. By setting up the rotating sealing plate, all connection ports can be sealed, preventing external wind, sand, and dust from contaminating them. A fixed cylinder corresponding to the connection port is fixedly connected to the sealing plate, and a contact that passes through the sealing plate and inserts into the connection port is fixedly connected to the end of the elastic sliding component. The fixed cylinder protects the normally connected connection port, and when the contact is pulled out of the connection port using the elastic sliding component, contamination of the connection port is prevented. Simultaneously, quickly rotating the sealing plate allows the contact to be moved to another connection port for rapid connection port replacement, without causing any connection port to be contaminated by the external environment during replacement.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1-4 As shown: This utility model provides a quick-change device for the connection port of a charging connector: including a charging head 1 with prongs, and a connecting cable 4 connected to the charging head 1 in a circuit.

[0021] The charging head 1 has several circumferentially distributed connection ports 5. The sealing plate 2 is rotatably connected to the charging head 1, and all the connection ports 5 are located inside the sealing plate 2, which can ensure the protection of all the connection ports 5. A fixed cylinder 3 corresponding to the connection port 5 is fixedly connected to the sealing plate 2. An elastic sliding component is provided on the fixed cylinder 3. A contact 6 that passes through the sealing plate 2 and is inserted into the connection port 5 is fixedly connected to the end of the elastic sliding component, and the contact 6 is electrically connected to the connecting wire 4.

[0022] like Figure 4 As shown, the elastic sliding assembly includes a sliding rod 8, a limiting block 9, and a spring 10. The sliding rod 8 is slidably disposed within the fixed cylinder 3, and the limiting block 9 is fixedly sleeved on the sliding rod 8. The spring 10 is sleeved on the sliding rod 8, and the positions of the spring 10 and the limiting block 9 correspond. The contact 6 is fixedly connected to the lower end of the sliding rod 8. The spring 10 has a reserved compression amount, which can continuously exert pressure on the limiting block 9, thereby increasing the tightness of the contact 6 at the lower end of the sliding rod 8 and the connection port 5. An operating block 11 fixedly connected to the sliding rod 8 is provided above the fixed cylinder 3, which allows the operator to control the connection of the contact 6 by operating the operating block 11.

[0023] like Figure 4 As shown, the connecting wire 4 passes through the inside of the sliding rod 8 and is connected to the contact 6 in the circuit. The sliding rod 8 and the limiting block 9 are both insulators to avoid affecting the normal circuit connection between the connecting wire 4 and the contact 6.

[0024] like Figure 3 As shown, there are six connection ports 5 with the same shape and different transmission protocols. By selecting connection ports 5 with different transmission protocols, different charging tilts can be accommodated. The six connection ports 5 are evenly distributed in a circumferential shape on the charging head 1, so that when the sealing plate 2 rotates, the contacts 6 can connect to all the connection ports 5. Since the connection ports 5 are blocked by the sealing plate 2 and the fixing cylinder 3, six indicator rods 7 corresponding to the connection ports 5 are fixedly installed on the outer wall of the charging head 1, which can serve as an indicator, thereby making it convenient for the staff to select the appropriate connection port 5.

[0025] The principle of this utility model

[0026] like Figure 1 , 2As shown in Figure 3, when using this application, the contact 6 can be inserted into one of the connection ports 5, so that the connecting wire 4 is connected to the charging head 1 circuit. At this time, the sealing plate 2 and the fixing cylinder 3 can protect the connection ports 5 that are in use and all unused, preventing the invasion of external wind, sand and dust; when it is necessary to replace the connection port 5 that the connecting wire 4 is connected to, such as Figure 4 As shown, the operator operates the operating block 11, pulls the sliding rod 8 upward to retract the contact 6 into the fixed cylinder 3, and at the same time, the limiting block 9 compresses the spring 10. After the contact 6 is separated from the connection port 5, the sealing plate 2 can be rotated to drive the fixed cylinder 3 and the contact 6 to rotate. According to the marking rod 7, the appropriate connection port 5 is selected so that the connection port 5 corresponds to the contact 6. The operating block 11 is moved downward to insert the contact 6 into the connection port 5. The replacement of the connection port 5 can be completed quickly. During the replacement process, all connection ports 5 are in a closed state, which can effectively prevent external wind, sand and dust from contaminating the connection ports 5.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
