[0036] An enhanced multi-core connector and its manufacturing process according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] For easier understanding, see Figure 1 to Figure 2 , an embodiment of an enhanced multi-core connector and a manufacturing process thereof provided by the present invention comprises:

[0039] A plurality of conductive terminals 2 are disposed inside the connector insulating body 1; each conductive terminal 2 includes a contact portion 3 and a soldering portion, wherein the contact portion 3 is located on the outer surface of the connector insulating body 1 to facilitate physical connection with an external device, and the soldering portion is used to form a stable soldering connection with the built-in circuit board;

[0040] A reinforcement structure 4 is integrated in the connector insulation body 1, which is intended to improve the mechanical strength of the connector and reduce electromagnetic interference by optimizing the arrangement between the conductive terminals 2, thereby effectively improving the electrical characteristics; the reinforcement structure 4 includes a plurality of metal reinforcements 41, which are embedded in important parts of the connector insulation body 1 using a precision molding process to provide additional support and improve signal transmission efficiency; the metal reinforcements 41 are manufactured using selective laser sintering 3D printing technology, which can achieve complex structures and increase the tensile strength and bending resistance of the connector;

[0041] The connector insulating body 1 is made of high-performance polymer material, which can maintain the integrity of the connector's functions even in extreme environments, and its material formula is specially designed to meet the requirements of high-speed data transmission; the conductive terminal 2 is made of copper alloy material and coated with a gold-plated layer on its surface to enhance conductivity and corrosion resistance; the reinforcement structure 4 also includes a shielding layer arranged in the connector insulating body 1, and the shielding layer is composed of conductive material to further reduce electromagnetic interference and ensure the quality of signal transmission; an insulating layer is arranged between the shielding layer and the metal reinforcement 41 to prevent direct electrical contact between the two, thereby ensuring safe and reliable operation of the connector.

[0042] It should be noted that the connector insulating body 1 is made of high-performance polymer materials so that it can meet the requirements of high-speed data transmission. The structural setting of the conductive terminal 2 corresponds to the different requirements of the contact part 3 and the welding part. The contact part 3 needs to be exposed to the outside so as to establish a physical connection with the external device; while the welding part needs to form a reliable welding connection with the circuit board built into the connector insulating body 1. The conductive terminal 2 will be made of a copper alloy material with good conductivity and corrosion resistance, and a gold plating layer will be set on its surface. The reinforcement structure 4 is an important part of the connector. The reinforcement structure 4 not only improves the mechanical strength of the connector, but also reduces electromagnetic interference by optimizing the spatial layout between the conductive terminals 2. The metal reinforcement 41 is embedded in the key position of the connector insulating body 1 using precision molding technology. These reinforcements will be made by selective laser sintering 3D printing technology to achieve complex geometric shapes. A shielding layer is set in the connector insulating body 1 to further reduce electromagnetic interference and ensure the quality of signal transmission. An insulating layer will be set between the shielding layer and the metal reinforcement 41 to prevent electrical contact and ensure the safety and stability of the connector.

[0043] Among them, selective laser sintering is an additive manufacturing technology that uses lasers as an energy source to sinter powder materials, such as nylon and polycarbonate, layer by layer to build three-dimensional objects. In this process, the laser scans the powder bed according to the cross-sectional pattern generated by the computer, so that the powder particles fuse together to form a solid material. After each layer is completed, the platform drops a certain height, and then a new layer of powder is added, and the process is repeated until the entire part is completed; Selective laser sintering 3D printing technology uses SLS technology to manufacture metal reinforcements41, so specifically, it may be the use of metal powder or metal matrix composites through SLS technology to create parts with complex geometries.

[0044] Example 2

[0045] The present invention also protects a manufacturing process of an enhanced multi-core connector, comprising the following steps:

[0046] a) providing a connector insulating body 1 including a plurality of conductive terminals 2, wherein the conductive terminals 2 include a contact portion 3 exposed to the outer surface of the connector insulating body 1 and a welding portion for forming a welding connection with a built-in circuit board;

[0047] b) using selective laser sintering 3D printing technology to prepare metal reinforcement members 41, and embedding a plurality of metal reinforcement members 41 at key positions of the connector insulation body 1;

[0048] c) embedding the metal reinforcement 41 into the connector insulating body 1;

[0049] d) manufacturing the conductive terminal 2, wherein the conductive terminal 2 is made of a copper alloy material;

[0050] e) A shielding layer made of a conductive material is installed in the connector insulating body 1 , and an insulating layer is provided between the shielding layer and the metal reinforcement 41 .

[0051] Before step a), the method also includes designing a three-dimensional model of the connector insulating body 1, the conductive terminal 2 and the reinforcement structure 4, and optimizing the three-dimensional model by computer-aided design software.

[0052] After step d), the method further includes performing an electrical performance test on the connector to ensure that the shielding layer effectively reduces electromagnetic interference and verifies the signal transmission quality.

[0053] In step d), a gold-plated layer is provided on the surface of the conductive terminal 2 .

[0054] It should be noted that the three-dimensional model of the connector insulating body 1, the conductive terminal 2 and the reinforcement structure 4 is designed using software, and the metal reinforcement 41 is produced using selective laser sintering 3D printing technology.

[0055] The metal reinforcement 41 is embedded into the key position of the already formed connector insulating body 1 .

[0056] The conductive terminal 2 is made of copper alloy material, and a gold layer is plated on its surface. A shielding layer is installed in the connector insulation body 1, and an insulating layer is provided between the shielding layer and the metal reinforcement 41.

[0057] Finally, the finished connector is tested for electrical performance.

[0058] Working principle: The connector insulation body 1 is made of high-performance polymer material, which can maintain the functional integrity of the connector under extreme working conditions. Each conductive terminal 2 includes a contact portion 3 and a welding portion. The contact portion 3 is exposed to the outer surface of the connector insulation body 1 to establish a physical connection with an external device; the welding portion is used to form a reliable welding connection with the built-in circuit board of the connector insulation body 1. The conductive terminal 2 is usually made of copper alloy material, and a gold plating layer is provided on its surface to improve the conductivity and corrosion resistance. The reinforcement structure 4 integrates a plurality of metal reinforcements 41, which are embedded in the key positions of the connector insulation body 1 through precision molding technology to provide additional support. The metal reinforcement 41 is prepared by selective laser sintering SLS technology, which can realize complex geometric shapes, thereby enhancing the tensile strength and bending resistance of the connector. The shielding layer is made of conductive material and is arranged in the connector insulation body 1 to further reduce electromagnetic interference and ensure the quality of signal transmission. An insulating layer is provided between the shielding layer and the metal reinforcement 41 to prevent electrical contact and ensure the safety and stability of the connector.

[0059] When the enhanced multi-core connector is inserted into the corresponding socket, the contact portion 3 contacts the corresponding terminal in the socket to establish a physical connection. At this time, data or electricity can be transmitted through the reliable connection between the welding portion and the built-in circuit board. Due to the gold-plated layer on the surface of the conductive terminal 2, the contact resistance is low and the conductivity is good. At the same time, the gold-plated layer also provides excellent corrosion resistance. The metal reinforcement 41 in the enhanced structure 4 enhances the overall mechanical strength of the connector, making the connector more durable, and its complex geometric shape helps to optimize the signal transmission efficiency. The presence of the shielding layer reduces the electromagnetic interference between the conductive terminals 2, further improves the electrical performance, and ensures the quality of signal transmission.
