Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The first direction X, the second direction Z and the third direction Y provided in the embodiments of the present application are mutually perpendicular.

[0025] The specific implementation methods of the present application are described below by way of examples:

[0026] like Figures 1 to 6As shown, an embodiment of the present application provides an electronic connector, including: a first shell 300, the first shell 300 has a first accommodating cavity 330, a first opening 331 connected to the first accommodating cavity 330 is provided on one side along the first direction X, and a second opening 332 connected to the first accommodating cavity 330 is provided on one side of the first shell 300 along the second direction Z, and the first opening 331 and the second opening 332 are connected; a plug-in portion 200, the plug-in portion 200 is provided in the first accommodating cavity 330; wherein the first direction X and the second direction Z intersect, and a guide channel 322 is provided on the side of the first shell 300 away from the first accommodating cavity 330, and the guide channel 322 extends along the second direction Z. Specifically, the first accommodating cavity 330 provided in the first shell 300 is used to support the plug-in part 200, and only a part of the structure of the plug-in part 200 is located in the first accommodating cavity 330, that is, along the first direction X, part of the structure of the plug-in part 200 is located on the outside of the first opening 331, and along the second direction Z, another part of the structure of the plug-in part 200 is located on the outside of the second opening 332.

[0027] like Figures 3 to 5 As shown, the guide channel 322 and the first opening 331 are opposite to each other, and the direction of the guide channel 322 can be the same as the direction of the second opening 332. When the plug-in part 200 is heated, the guide channel 322 can guide the heat flow (hot air) when the plug-in part 200 is heated, so that the plug-in part 200 can be fully heated, and the soldering flux coated on the plug-in part 200 can be fully volatilized after heating, and then the solder paste is sprayed to assist the electrical connection between the components. After the components are connected, the plug-in part 200 needs to be cooled so that the solder paste can condense to fix the components. The guide channel 322 can improve the heat dissipation efficiency of the solder paste at the plug-in part 200, avoid overheating of the plug-in part 200, and cause poor connection of components inside the electronic connector, thereby improving the connection strength of the components inside the electronic connector and extending the service life of the electronic components.

[0028] In the embodiment of the present application, the soldering flux is mainly used to clean the soldering surface of the plug part 200. Before using the soldering flux, the soldering surface of the plug part 200 should be cleaned to ensure that there is no oil stain and oxide. After cleaning, an appropriate amount of soldering flux is applied to the soldering surface of the plug part 200. Column soldering helps to remove the oxide layer and impurities on the soldering surface of the plug part 200, and provides good wetting and fluidity, so that the solder paste can more easily form a correct soldering on the soldering surface.

[0029] In an embodiment of the present application, solder paste is used to connect the components on the plug-in part 200. Solder paste is a semi-solid material containing solder particles and flux. Solder paste is mainly used for soldering on surface mount technology (SMT) and printed circuit boards (PCB) of the plug-in part 200. Solder paste is usually provided in the form of a spiral tube or syringe with solder paste particles. Apply or spray an appropriate amount of solder paste on the welding surface, and the solder particles in the solder paste will melt during the welding process to form welding points. In mounting technology and PCB welding, tools such as heating and hot air nozzles are usually used to heat the solder paste to melt the solder and form a stable connection.

[0030] like Figures 3 to 6 As shown, in the embodiment of the present application, the first shell 300 includes a connecting portion 310 and a guide portion 320, the connecting portion 310 is connected to the guide portion 320, the first accommodating cavity 330 is located at the connecting portion 310, the first opening 331 is located at a side of the connecting portion 310 away from the guide portion 320, and the guide channel 322 is located at a side of the guide portion 320 away from the connecting portion 310. Specifically, the first opening 331 is used to expose the plug-in portion 200 to the outside so as to facilitate the connection of the plug-in portion 200 with other devices or interfaces, and the main function of the guide channel 322 is to guide the heat flow to heat the plug-in portion 200. At the same time, since the first shell 300 is made of metal, preferably zinc alloy, the guide channel 322 can also reduce the use of metal materials, thereby reducing the weight and reducing the manufacturing cost of the first shell 300. It should be noted that when forming the guide channel 322, the center of gravity of the entire electronic connector needs to be considered. Generally speaking, the center of gravity of the electronic connector is located at the centralized connection between the plug-in portion 200 and the components.

[0031] like Figure 4 and Figure 5 As shown, in an embodiment of the present application, there are multiple guide channels 322, and adjacent guide channels 322 are separated by partitions 323; wherein, the guide channels 322 penetrate the top and bottom surfaces of the guide portion 320 along the third direction Y. Specifically, the guide channels 322 are multiple through-type through grooves, and this through-groove design can not only guide the heat flow during heating to the welding surface of the plug-in portion 200, but also guide the heat flow to dissipate upward during cooling, thereby accelerating heat dissipation. The guide channels 322 can reduce the volume of the guide portion 320, thereby reducing the heat absorbed by the guide portion 320, increasing the heat dissipation area of ​​the guide portion 320, and making the cooling speed of the guide portion 320 faster, thereby further driving the plug-in portion 200 to cool down. It is worth noting that the through-type guide channel 322 design can also improve production efficiency.

[0032] like Figure 3 , Figure 5 and Figure 6 As shown, in another embodiment of the present application, the guide channel 322 penetrates the bottom surface of the guide portion 320 along the third direction Y. Specifically, the top of the guide channel 322 does not penetrate the top surface of the guide portion 320. Through this half-channel design, the heat flow during heating can be guided to flow to the bottom surface, thereby better heating the welding surface of the plug part 200, accelerating the heating speed of the plug part 200, and making the flux on the plug part 200 volatilize more thoroughly.

[0033] like Figures 3 to 6 As shown, in the embodiment of the present application, the guide channel 322 has a bottom wall 321, and the bottom wall 321 is inclined in a direction away from the connecting portion 310. Specifically, when the plug-in portion 200 is heated, the first shell 300 is generally placed in a heating box, and a flowing airflow is introduced into the heating box to heat the plug-in portion 200. Therefore, in order to guide the airflow to converge toward the welding surface of the plug-in portion 200, the bottom wall 321 of the guide channel 322 is set to be inclined toward the welding surface of the connecting portion 310 and the plug-in portion 200, so that the airflow can be successfully guided to the welding surface when it flows through the guide channel 322. It is worth noting that when the top of the guide channel 322 does not penetrate the top surface of the guide portion 320, and the bottom wall 321 of the guide channel 322 is inclined, the drainage heating effect of the guide channel 322 is optimized.

[0034] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the electronic connector also includes a data board 400, the plug-in portion 200 includes a connection surface 210, the data board 400 is electrically connected to the connection surface 210, and the connection surface 210 passes through the second opening 332. Specifically, the data board 400 includes a PCB board, and the PCB board is electrically connected to the connection surface 210. It can be understood that the PCB board is a carrier of electronic components inside the electronic connector, and each circuit is connected by wiring of copper wires and other conductive elements. The PCB board provides a physical connection between electronic components and a path for the transmission of electrical signals. And the PCB board can serve as a structural skeleton of the electronic connector, providing stability and mechanical support for the electronic connector. At the same time, the layout design of the wires and electronic components on the PCB board helps to achieve high-speed signal transmission, and the electronic components, capacitors and resistors set on the PCB board can be used for signal control and management, and for enhancing signal quality, filtering, isolation and current control functions. The PCB board is also provided with a ground wire and a shielding layer to provide shielding protection against electromagnetic interference, thereby helping to reduce interference noise and maintain signal integrity and stability. Depending on the type of transmission signal, the plug-in portion 200 satisfies different connection protocols. The type of specific protocol can be selected according to the usage scenario, and the embodiments of the present application are not listed in detail here.

[0035] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the data board 400 is provided with a pin 410, and the pin 410 is away from the connection surface 210. Specifically, the pin 410 is used to connect a signal line, and the signal line is used to transmit a data signal, and the data signal is input to the data board 400 through the signal line for processing, or the data signal processed by the data board 400 is transmitted to other plug connectors to achieve effective transmission of the data signal.

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, in the embodiment of the present application, the electronic connector further includes a second housing 100, the second housing 100 has a second accommodating cavity 170, at least part of the first accommodating cavity 330 is located in the second accommodating cavity 170; wherein, at least part of the structure of the plug-in portion 200 is located in the second accommodating cavity 170. Specifically, the plug-in portion 200 is assembled in the first accommodating cavity 330 of the first housing 300 after being connected with the data board 400, and then the first housing 300 is connected and assembled with the second housing 100. Therefore, the plug-in portion 200 is not only located in the first accommodating cavity 330, but also in the second accommodating cavity 170, and the first accommodating cavity 330 is also located in the second accommodating cavity 170. The plug-in portion 200 is protected by the first housing 300 and the second housing 100, thereby reducing the surface of the plug-in portion 200 and components from being hit by the outside world, and extending the service life of the plug-in portion 200.

[0037] like Figure 1 , Figure 2 and Figure 5As shown, in the embodiment of the present application, along the second direction Z, the side wall of the second accommodating cavity 170 is provided with a slot 160 communicating with the second accommodating cavity 170, and the slot 160 is provided with a buckle 120; along the second direction Z, the connecting portion 310 has a card slot 311 that deviates from each other, and the buckle 120 is matched and connected with the card slot 311, so that the second shell 100 is connected with the first shell 300. Specifically, the second shell 100 includes a connecting end 110 and a plug-in end 140, and the second accommodating cavity 170 is located at the connecting end 110. The second accommodating cavity 170 is used to connect the first shell 300 and the plug-in portion 200. A third accommodating cavity is provided in the plug-in end 140, and the third accommodating cavity is communicated with the second accommodating cavity 170. The third accommodating cavity is used to provide an accommodating space when the electronic connector is connected to other plug connectors. The second accommodating chamber 170 includes at least two side walls, the slots 160 are respectively arranged on the two side walls, and the slots 160 are connected to the second accommodating chamber 170, and the buckle 120 is connected to a part of the slots 160. The position of the slot 311 on the connecting portion 310 corresponds to the position of the buckle 120. When the first shell 300 is inserted into the second accommodating chamber 170, the slot 311 and the buckle 120 are engaged with each other. It should be noted that both buckles 120 are elastic and tilted toward the second accommodating chamber 170. When the slot 311 slides into the specific position of the buckle 120, the buckle 120 can extend outward and rebound, thereby achieving an engaged connection.

[0038] like Figure 5 As shown, in the embodiment of the present application, a plug-in tube 150 is provided in the second accommodating cavity 170; when the second shell 100 is connected to the first shell 300, the portion of the plug-in portion 200 protruding from the first opening 331 is plugged into the plug-in tube 150. Specifically, the plug-in tube 150 is fixedly connected to the inner wall of the second accommodating cavity 170, and the plug-in tube 150 encloses the plug-in slot 130. When the plug-in portion 200 is inserted into the second accommodating cavity 170, the portion of the plug-in portion 200 exposed from the first accommodating cavity 330 is inserted into the plug-in slot 130 enclosed by the plug-in tube 150. The plug-in tube 150 is used to limit the position of the plug-in portion 200 to prevent the plug-in portion 200 from being displaced when plugging or moving, thereby causing poor interface connection with other devices.

[0039] The embodiment of the present application also provides a wiring harness product, including a cable; and an electronic connector provided by any one of the above items installed at the end of the cable. The electronic connector used in the wiring harness product can achieve all the effects described above, so the embodiment of the present application will not further elaborate on the beneficial effects of the electronic connector.
