DETAILED DESCRIPTION

[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 described embodiments 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 creative work 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, wherein the insulating base 30 is formed with a tongue 40, and the insulating base 30 covers the terminal group 20 and is arranged inside the housing 10. After assembly, the connector is connected to a matching connection port (not shown) for use;

[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 a starting point and an end point for 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 substrate 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 electrical conduction, and further, at least one The signal terminals 62 can transmit data signals respectively. The positive terminal 60, the ground terminal 61, and the contact portion 24 of the signal terminal 62 are respectively exposed on the upper surface of the tongue piece 40, and can also be respectively exposed on the lower surface of the tongue piece 40. The tongue piece 40 is used for single-sided matching connection ports. 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 piece 40 at the same time. The upper and lower surfaces of the tongue piece 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. The port is set to be connectable on both the upper and lower sides, and the connection is more convenient and quick;

[0049] The electrical terminal 21 is also integrally formed with a reinforcing rib 25, and the reinforcing rib 25 is extended at an angle and arranged 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 portions makes the electrical terminal 21 subject to more force directions, and reinforces the electrical terminal 21. During the process of stamping, electroplating, and assembling 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 on the side of the fixing portion 23. As a preferred solution, the reinforcing rib 25 can also be extended at an angle 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 to form an angle at the intersection of one surface of the reinforcing rib 25. 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 present invention is an arc angle. The contact portion 24 of the reinforcing rib 25 is extended at an angle according to processing requirements to reduce the glue encapsulation during the injection molding process. The stability and reliability of the contact portion 24 without glue encapsulation can be guaranteed when the end face is in contact with the conductive contact.

[0050] Furthermore, the reinforcing ribs 25 are arranged at angle intervals and extend on the sides of the welding portion 22, the fixing portion 23, and the contact portion 24. The reinforcing ribs 25 extending at angle intervals can respectively partially 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 substrate 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. Figure 17-Figure 21 As shown, the electrical terminal 21 with the reinforcing ribs 25 extending at angular intervals can be arranged in an L-shaped structure 70. The direction-changing nodes of the electrical terminal 21 in the L-shaped structure 70 can be arranged at the intervals of the reinforcing ribs 25. The reinforcing ribs 25 extending at intervals make the electrical terminal 21 in the L-shaped structure 70 change its shape without being restricted by the force of the reinforcing ribs 25. With the intervals of the reinforcing ribs 25 as endpoints, the L-shaped structure 70 can also be arranged on the welding portion 22, the fixing portion 23, and the contact portion 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 its shape occupies less space and has strong adaptability to the use environment. Electronic products using the electrical connector of the present invention 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 away 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 molding 80, puncture molding 81, and tearing molding 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 component 50, which is separately arranged on the other side of the contact portion 24. The split hook component 50 can be made of a material with higher strength and toughness than the electrical terminal 21, so that the hook portion has a longer durability. During the connection and use of the connector, the hook plays a 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 and the electrical terminal 21 are manufactured at the same time, saving the cost and time of producing the split hook member 50 separately, and eliminating the cumbersome process of assembling and stacking the hook member and the electrical terminal 21. It is more cost-saving to set it as an integrated hook member, simplify the manufacturing process, and have higher production efficiency; Fig.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 more preferably used in a connection environment without frequent movement and switching.

[0055] Further, the reinforcing rib 25 is 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 terminal 21 and the extended reinforcing rib 25 can be manufactured by ultra-precision milling process. Ultra-precision milling uses micron or even nanometer level precision for processing, and ensures high-precision output by strictly controlling control factors such as temperature, vibration and cutting force. During the processing, the relative movement between the tool and the workpiece is strictly constrained to ensure processing accuracy and surface quality.

[0057] In this solution, the electrical terminal 21 and the extended reinforcing rib 25 can be manufactured by a micro-molding process. The micro-molding process requires heating and dissolving the material and then injecting it into a set model. 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, easy to realize automation, and the precision of the manufactured finished product is very high. It can mold workpieces of complex shapes, and the quality of the molded workpieces is stable and has a wide range of applications.

[0058] In this solution, the electrical terminal 21 and the extended reinforcing rib 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 and uses a rolling tool to apply pressure to the surface of the workpiece to cause the workpiece metal to flow plastically and deform the rolled metal properties. The roll forming process is used to manufacture the electrical terminal with extended reinforcing ribs, while ensuring dimensional accuracy and being more efficient.

[0059] In this solution, the electrical terminal 21 and the extended reinforcing rib 25 can be manufactured by laser micromachining. Laser micromachining is a technology that utilizes the characteristics of the interaction between laser beam and matter to process materials. When the laser beam is irradiated onto 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, gasification or shedding. The micro laser processing technology has very high precision and very small error.

[0060] In this solution, the electrical terminal 21 and the extended reinforcing rib 25 can be manufactured by a chemical etching process. The chemical etching process is to draw lines on the metal surface coated with an anti-corrosion layer, scrape off the lines of the anti-corrosion layer to expose the metal parts, and then immerse the metal parts in an etching solution. The scratches exposed on the metal parts are etched into a set shape. The chemical etching process can obtain a high-precision processing effect. The etched products have no burrs, no dirt, and a smooth surface, which is suitable for high-precision processing requirements.

[0061] The present invention can manufacture the electrical terminal 21 and the extended reinforcing rib 25 by electrochemical machining. Electrochemical machining is the process of machining metal materials by electrochemical reaction. During the machining process, the metal material acts as an anode and is connected to the positive electrode of the power supply. The tool electrode acts as a cathode and is connected to the negative electrode of the power supply. When the power is turned on, the metal on the anode will dissolve to form ions that enter the electrolyte, while a reduction reaction will occur on the cathode to deposit 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 obtain higher machining accuracy and excellent surface quality. It is suitable for machining parts with high precision requirements.

[0062] The present invention can manufacture the electrical terminal 21 and the extended reinforcing rib 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, the metal material is directly deformed by pressure in the mold with the help of the power of conventional or special stamping equipment, so as to obtain a workpiece with a 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, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
