Description

Technical Field

[0001] This utility model relates to the field of waterproof wire harness technology, and more specifically, to a waterproof wire harness with a PCB module. Background Technology

[0002] With the continuous development of technological innovation, the continuous progress of human civilization, and the further improvement of intelligent and Internet of Things technologies, all devices can be remotely controlled and monitored through network connections. For example, the State Grid Corporation of China ensures that all electricity generated by the power system is connected to the grid.

[0003] For example, photovoltaic power generation produces direct current (DC), which needs to be converted to alternating current (AC) by an inverter. The generated electricity is then classified and controlled to be used by different electrical devices with different operating voltages. If the State Grid wants to connect photovoltaic power generation to the grid, the first step is to connect the inverter to the data acquisition terminal in its power grid.

[0004] However, the existing common communication protocol is RS485. The inverter has a built-in communication port, and the data rod connects to the inverter host through the communication port. If the State Grid wants to connect the inverter to the data acquisition or metering equipment used in its own power grid, it must do so through a data cable. Since photovoltaic equipment is basically installed in complex environments such as high solar radiation, high altitude and uninhabited areas, it has very strict requirements for its lifespan. The standard lifespan of photovoltaic equipment in the European Union is 25 years. Under such high requirements, if it is to maintain an effective connection for 25 years, the connection cable must have characteristics such as high lifespan, high reliability, high stability and adaptability to high temperature and high humidity.

[0005] In addition, to achieve the ultimate goal of remote control, it is necessary to manually connect the inverter to the State Grid equipment using a data cable. Considering the equipment and installation labor costs, it is necessary to integrate the data cable and simplify the equipment. Utility Model Content

[0051] According to an embodiment of the present invention, a waterproof wire harness with a PCB module is provided.

[0052] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0053] In practical use, the waterproof wire harness with PCB module according to this utility model includes a sealing ring 15, a female core 14, a nut 13, a female terminal 12, a lower protective shell 10, a first core wire 7, a wire 6, an upper protective shell 9, an outer membrane 11, a PCB module 5, a second core wire 8, a male terminal 4, and a male core 3.

[0054] First, put the inner ring 1501 of the sealing ring on the outer ring 1401 of the female core. After putting it on, insert the female terminal 12 into the corresponding female core terminal socket 1402.

[0055] To ensure that the female terminal 12 has a certain holding force when inserted into the female core terminal socket 1402, the female terminal 12 is provided with a female terminal locking point 1203. The female terminal locking point 1203 and the female core terminal socket 1402 are in an interference fit. The interference fit ensures that the female terminal 12 and the female core terminal socket 1402 have a good holding force and will not easily fall out of the female core socket.

[0056] To improve the contact performance between the female terminal 12 and the male terminal 4, the female terminal 12 is designed with two contact areas, which include a number of first female terminal contact surfaces 1201 and second female terminal contact surfaces 1202.

[0057] To further enhance the insertion and extraction force generated when the male terminal 4 contacts the female terminal 12, the second female terminal contact surface 1202 is a one-piece structure. The one-piece structure creates a cantilever beam effect. Under the action of the cantilever beam, it not only generates a large insertion and extraction force, but also has a high insertion and extraction life.

[0058] After the female terminal 12 is assembled, the nut 13 is put onto the female core 14. To ensure that the nut 13 will not fall off the female core 14, the nut 13 and the female core 14 are respectively provided with a nut limiting plane 1302 and a female core limiting plane 1403. Through the action of the limiting plane, the nut 13 will not be able to fall off the female core 14 in the X-axis direction.

[0059] Similar to the female terminal 12, the male terminal 4 is inserted into the male core socket 303. To ensure that the male terminal 4 has a certain holding force when inserted into the male core socket 303, the male terminal 4 is provided with a male terminal locking point 402. The male terminal locking point 402 and the male core socket 303 are in an interference fit. The interference fit ensures that the male terminal 4 and the male core socket 303 have a good holding force and will not easily fall out of the male core socket 303.

[0060] After the male terminal 4 and the female terminal 12 are assembled, the first copper wire 702 of the first core wire is soldered to the solder cup 401 of the male terminal, the second copper wire 703 of the first core wire is soldered to the mounting hole of the PCB module 5, the first copper wire 802 of the second core wire is soldered to the solder cup 1204 of the female terminal, and the second copper wire 803 of the second core wire is soldered to the mounting hole of the PCB module 5. After soldering, the connection between the male connector 2, the female connector 1 and the PCB module 5 is completed.

[0061] Next, the entire PCB module 5 is placed into the cavity 1003 of the lower protective shell 10. The lower protective shell 10 is provided with a plurality of first lower protective shell core wire holes 1001 and second lower protective shell core wire holes 1002. The first lower protective shell core wire holes 1001 and second lower protective shell core wire holes 1002 respectively cooperate with the first core wire sheath 701 and the second core wire sheath 801. Under the action of the first lower protective shell core wire holes 1001 and second lower protective shell core wire holes 1002, the first core wire sheath 701 and the second core wire sheath 801 will be well positioned and protected.

[0062] After male connector 2 and female connector 1 are soldered to PCB module 5 via core wires, copper wire 602 of the electrical wire is then soldered to PCB module 5.

[0063] After welding, the upper protective shell 9 and the lower protective shell 10 are assembled. The upper protective shell slot 903 designed on the upper protective shell 9 and the lower protective shell hook 1004 designed on the lower protective shell 10 are effectively engaged. After engagement, the lower protective shell hook 1004 hooks the upper protective shell slot 903, and the assembly is completed after hooking.

[0064] After assembly, the upper protective shell 9 and the lower protective shell 10 will be integrated. At this time, the outer sheath 601 of the wire 6 will also be positioned and protected by the wire hole 904 of the upper protective shell and the wire hole 1005 of the lower protective shell.

[0065] After the upper protective shell 9 and the lower protective shell 10 are assembled, the entire upper protective shell 9, the lower protective shell 10 and the wire 6 are placed into the mold for injection molding. During the molding process, due to the large molding pressure and molding temperature, in order to protect the upper protective shell 9 and the lower protective shell 10 from being broken or melted by the pressure, the upper protective shell 9 and the lower protective shell 10 are made of plastic materials with a higher temperature resistance level than the outer film material.

[0066] In addition, the upper protective shell 9 is provided with several upper protective shell reinforcing pillars 901 and upper protective shell reinforcing blocks 902, and the lower protective shell 10 is provided with several lower protective shell reinforcing pillars 1006. Under the action of the reinforcing pillars and reinforcing blocks, the impact resistance of the upper protective shell 9 and the lower protective shell 10 will be enhanced.

[0067] The outer film shape is obtained by injection molding. After the outer film 11 is formed, a wire protection clip 1102 is designed on it. This wire protection clip 1102 can ensure that the copper wire of the wire 6 will not fall off the PCB module 5 when it swings left and right or up and down, thus preventing communication failure.

[0068] To further enhance the overall controllability of the product, the outer membrane 11 is also designed with several outer membrane grooves 1101. These outer membrane grooves 1101 provide a better feel, making the product easier and more comfortable to use.

[0069] This product is ultimately installed in devices that require communication connections, such as the connection between State Grid equipment and inverters or communication protocol converters. This product is designed with a device communication access port, and the type of this port is not fixed. It can be a crystal head, a USB 2.0 or 3.0 port, a copper tube terminal, etc.

[0070] In summary, by utilizing the above-mentioned technical solution of this utility model and through the optimized and improved design of the product of this utility model, the waterproof wire harness can serve as a waterproof connection cable for communication ports, effectively connecting the inverter, acquisition terminal, and data stick to achieve communication. This enables it to possess waterproof, anti-detachment, and high temperature and humidity resistance characteristics, and can also simplify protocol converter equipment, thereby achieving the beneficial technical effect of saving equipment procurement costs and labor installation costs.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
