[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figure 1-Figure 24 shown.

[0047] An electrical connector includes a housing 10, a terminal group 20, and an insulating base 30. The insulating base 30 is formed with a tongue 40. The insulating base 30 covers the terminal group 20 and is disposed inside the housing 10. After assembly, the connector is connected to a matching connection port (not shown).

[0048] The terminal group 20 includes at least two electrical terminals 21, one of which is a positive terminal 60 and the other is a ground terminal 61. The two terminals form the starting point and end point of providing electrical energy, so that the connector can provide electrical energy. The electrical terminal 21 includes a welding portion 22, a fixing portion 23, and a contact portion 24, wherein the welding portion 22 extends from the back of the insulating base 30, the welding portion 22 welds the conductive wire, the fixing portion 23 fixes the position of the electrical terminal 21, the contact portion 24 is horizontally protruded upward or downward on the fixing portion 23 and is respectively exposed on the surface of the tongue 40, the contact portion 24 on the surface of the tongue 40 is connected to the matching port for conductive use, and further, at least one According to the signal terminal 62, the signal terminal 62 can transmit data signals respectively. The contact portion 24 of the positive terminal 60, the ground terminal 61, and the signal terminal 62 are respectively exposed on the upper surface of the tongue 40, and can also be respectively exposed on the lower surface of the tongue 40. The tongue 40 is matched with the connection port on one side. According to user customization requirements, the contact portion 24 of the terminal can also be exposed on the upper and lower surfaces of the tongue 40 at the same time. The upper and lower surfaces of the tongue 40 are respectively exposed to the positive terminal 60, the ground terminal 61 and multiple signal terminals 62 for use, ensuring the reliability and stability of the electrical connector. It is set as a port that can be connected on both the upper and lower sides, which is more convenient and quick to connect and use.

[0049] The electrical terminal 21 is further integrally formed with a reinforcing rib 25, which is arranged at an angle to extend on at least one side of the welding portion 22, the fixing portion 23, and the contact portion 24. The reinforcing rib 25 formed by the electrical terminal 21 and the side extensions makes the electrical terminal 21 more subject to force, thereby reinforcing the electrical terminal 21. During the stamping, electroplating, and assembly of the electrical terminal 21, the electrical terminal 21 reinforced by the reinforcing rib 25 is not easily deformed by external force collision, thereby improving the stability of the electrical terminal 21. Figure 7 As shown, specifically, the reinforcing rib 25 extends at an angle to the side of the fixing portion 23. As a preferred solution, the reinforcing rib 25 can also be extended at an angle and arranged on the side of the welding portion 22 and the side of the contact portion 24. The contact surface of the contact portion 24 extends the intersection of the reinforcing rib 25 to form an angle. The angle can be set to any one of an arc angle, an acute angle, a right angle, and an obtuse angle. The schematic diagram provided by the solution of the utility model is an arc angle. The contact portion 24 of the reinforcing rib 25 is extended at an angle according to processing requirements to reduce glue encapsulation during the injection molding process. The stability and reliability of the end face of the contact portion 24 without glue encapsulation can be guaranteed when in conductive use.

[0050] Furthermore, the reinforcing ribs 25 are arranged at angular intervals extending on the sides of the welding portion 22, the fixing portion 23, and the contact portion 24. The reinforcing ribs 25 extending at angular intervals can respectively locally reinforce the stability of the welding portion 22, the fixing portion 23, and the contact portion 24. The electrical terminal 21 with the reinforcing ribs extended can be positioned more accurately and more firmly during the injection molding of the insulating base 30. The inner angle formed by the reinforcing ribs 25 extending at an angle on the welding portion 22 can also position the conductive wire at the welding portion 22. The positioned conductive wire will not slide away during welding, which facilitates the welding work between the welding portion 22 and the conductive wire. Figures 17-21 As shown, the electrical terminal 21 with the reinforcing ribs 25 extending at angular intervals can be set in an L-shaped structure 70, and the direction-changing node of the electrical terminal 21 in the L-shaped structure 70 can be set at the intervals of the reinforcing ribs 25. The reinforcing ribs 25 extended at intervals make the electrical terminal 21 in the L-shaped structure 70 change shape without being restricted by the force of the reinforcing ribs 25. With the intervals of the reinforcing ribs 25 as end points, the L-shaped structure 70 can also be set on the welding part 22, the fixing part 23, and the contact part 24 of the electrical terminal 21, so that the overall shape of the electrical terminal 21 is changed into a regular or irregular special-shaped terminal body. According to actual applications, the connector made of the special-shaped terminal body that can change shape occupies less space and has strong adaptability to the use environment. Electronic products using the electrical connector of the utility model can be made thinner and more precise.

[0051] Furthermore, the reinforcing rib 25 is integrally extended at an angle on the sides of the welding portion 22, the fixing portion 23, and the contact portion 24. The inner angle formed by the welding portion 22 and the reinforcing rib 25 can position the conductive wire at the welding portion 22, and the positioned conductive wire will not slide during welding. The reinforcing rib 25 extending from the fixing portion 23 and the contact portion 24 makes the injection molding of the insulating base 30 to fix the electrical terminal 21 more precise and the combination more firmly. Furthermore, the reinforcing rib 25 formed by integral extension arranges the welding portion 22 and the fixing portion 23 in a straight line structure, and there is no interval between the welding portion 22, the fixing portion 23, and the contact portion 24. The electrical terminal 21 with the integrally extended reinforcing rib 25 in a straight line structure has better overall strength and overall stability than the electrical terminal 21 with the reinforcing rib extended at intervals.

[0052] Furthermore, the protruding contact portion 24 is formed by any one of the processes of stretching forming 80, puncture forming 81, and tearing forming 82. Through the above processes, the contact portion 24 can be stretched vertically to another plane, and the contact portion 24 stretched vertically to another plane is exposed on the surface of the tongue piece 40. The contact portion 24 exposed on the surface of the tongue piece 40 is more stably and reliably connected.

[0053] like Figure 15-16 As shown, it also includes a split shielding hook part 50, which is separately arranged on the other side of the contact part 24. The split hook part 50 can be made of a material with higher strength and toughness than the electrical terminal 21, so that the hook part has a longer durability. During the connection and use of the connector, the hook plays the function of fixing the connector. The fixed connector will not be easily disconnected when subjected to a certain degree of vibration and pulling force, making the connector connection and use process more stable.

[0054] like Figure 15-17 As shown, it also includes an integrated shielding hook member 51, which is integrally arranged on the other side of the contact portion 24. The integrated hook member 51 is produced at the same time as the electrical terminal 21, saving the cost and time of producing the separate hook member 50 separately, and eliminating the tedious process of assembling and stacking the hook member and the electrical terminal 21. Setting it as an integrated hook member saves costs, simplifies the production process, and has higher production efficiency; as shown Figure 24 As shown, the hook member 52 can also be formed when the insulating base 30 is injection molded. The insulating base 30 material forms a connector of the hook member 52, which has higher production efficiency and lower cost, and is better used in a connection environment without frequent movement and switching.

[0055] Furthermore, the reinforcing ribs 25 are formed by any one of ultra-precision milling, micro-molding, roll forming, laser micro-machining, chemical etching, electrochemical machining, and micro-stamping.

[0056] In this solution, the electrical terminals 21 and the extended reinforcing ribs 25 can be manufactured by ultra-precision milling. Ultra-precision milling uses micron or even nanometer-level precision to perform processing. By strictly controlling factors such as temperature, vibration, and cutting force, high-precision output is ensured. During the processing, the relative motion between the tool and the workpiece is strictly constrained to ensure processing accuracy and surface quality.

[0057] In this solution, the electrical terminals 21 and the extended reinforcing ribs 25 can be manufactured by a micro-molding process. The micro-molding process requires heating and melting the material and then injecting it into a set mold. After cooling and molding, the workpiece of the set model style can be obtained. The production speed of micro-molding injection molding is very fast and easy to automate. The finished product is very high in precision and can be molded into workpieces of complex shapes. The molded workpieces have stable quality and a wide range of applications.

[0058] In this solution, the electrical terminals 21 and the extended reinforcing ribs 25 can be manufactured by a roll forming process. Roll forming is a pressure finishing process that utilizes the cold plasticity of metal at room temperature. A rolling tool is used to apply pressure to the surface of the workpiece, causing the workpiece metal to undergo plastic flow and deform the rolled metal properties. The roll forming process ensures dimensional accuracy while also being more efficient in manufacturing electrical terminals with extended reinforcing ribs.

[0059] In this solution, the electrical terminals 21 and the extended reinforcing ribs 25 can be manufactured by laser micromachining. Laser micromachining is a technology that utilizes the characteristics of the interaction between laser beams and materials to process materials. When the laser beam is irradiated on the surface of the material, due to the high energy density of the laser, the material in the smiling area will quickly absorb the light energy and convert it into heat energy. The heat energy will cause the material to heat up locally and reach a state of melting, vaporization or shedding. The micro laser processing technology is very precise and the error is extremely small.

[0060] In this solution, the electrical terminals 21 and the extended reinforcing ribs 25 can be manufactured by a chemical etching process. The chemical etching process involves scratching a metal surface coated with an anti-corrosion layer, scraping off the lines of the anti-corrosion layer to expose the metal part, and then immersing the metal part in an etching solution. The scratches on the metal part are etched into a predetermined shape. The chemical etching process can achieve high-precision processing results. The etched product is free of burrs and dirt, has a smooth surface, and is suitable for processing requirements requiring high precision.

[0061] This solution can produce the electrical terminal 21 and the extended reinforcing rib 25 through an electrochemical machining process. Electrochemical machining is the process of machining metal materials using electrochemical reactions. During the machining process, the metal material acts as an anode, connected to the positive electrode of the power supply, and the tool electrode acts as a cathode, connected to the negative electrode of the power supply. When the power is turned on, the metal on the anode will dissolve, forming ions that enter the electrolyte, while a reduction reaction occurs on the cathode, depositing metal. This electrochemical reaction causes the metal material to dissolve and deposit according to the shape of the tool electrode, thereby achieving the purpose of machining. Electrochemical machining is not limited by the hardness and toughness of the metal material. It can machine complex surfaces and cavities, and can achieve high machining accuracy and excellent surface quality. It is suitable for machining parts with high precision requirements.

[0062] This solution can produce the electrical terminals 21 and the extended reinforcing ribs 25 through a micro-stamping process. The working principle of the stamping machine is to drive the flywheel through an electric motor, and drive the crank connecting rod mechanism through a clutch and a transmission gear to move the slider up and down, thereby driving the mold to form the metal material. During the stamping process, with the help of the power of conventional or special stamping equipment, the metal material is directly subjected to pressure in the mold to be deformed, thereby obtaining a workpiece with the shape, size and performance set by the mold. The micro-stamping process has the characteristics of high efficiency and energy saving, low noise, flexible adaptability, automation and high-precision processing.

[0063] Furthermore, the product realized by this solution can be any one of the Type-c connector, Lightning connector, micro USB connector, Mini USB connector, and HDMI connector. This solution is a type-c female socket.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
