Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a Type-C connector with a built-in reinforcement structure. Background Technology

[0002] As a new generation of universal serial bus interface standard, the Type-C connector represents a significant improvement over traditional Type-A and Type-B connectors in terms of structural design and user experience. One of its most prominent advantages is that it completely solves the long-standing problem of mis-insertion in traditional USB interfaces. The Type-C interface employs a centrally symmetrical design, eliminating the need to distinguish between the correct and reverse orientation when inserting the plug. Furthermore, its accompanying cables are also direction-independent during connection. This physically eliminates the risk of connection failure or device interface damage due to mis-insertion or reverse insertion, greatly improving ease of use and reliability.

[0003] However, despite the significant breakthrough in interface design, Type-C connectors still have limitations in mechanical structure in some products currently on the market. For example, some products lack overall mechanical strength, making it difficult to meet the requirements of high-end customers for insertion and removal force and durability. In addition, some products use a modular structure, which makes them prone to deformation or even structural damage when subjected to repeated insertion and removal operations or external mechanical stress, affecting connection stability and product lifespan.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Type-C connector with a built-in reinforcement structure, comprising a main shell, a core, a first inner core, a second inner core, and conductive terminals; The rubber core is provided with a rubber block and a tongue plate. The lower end of the rubber block is provided with a contact surface. The rubber block is fastened by the main housing clamp. The tongue plate extends into the interior of the main housing. The conductive terminal includes a first terminal and a second terminal, which are integrally formed with the first inner core and the second inner core by a pre-embedded injection molding process, respectively. A reinforcing clip is sandwiched between the first inner core and the second inner core; After the first inner core, the second inner core, and the reinforcing clip are assembled, a second injection molding process is performed to form a rubber core on the outside of the first inner core, the second inner core, and the reinforcing clip, forming an integrated structure.

[0007] As a further embodiment of this utility model: after the core is formed on the outside of the first inner core, the second inner core and the reinforcing clip by secondary injection molding, both the first terminal and the second terminal are formed with welding feet that extend through the contact surface.

[0008] As a further embodiment of this utility model: a second outer shell is provided outside the main shell, and the lower ends of the second outer shell are provided with locking feet.

[0009] As a further embodiment of this utility model: after the first inner core and the second inner core are assembled, a clamping groove is formed inside, and the clamping groove is opened according to the outer contour of the reinforcing clip.

[0010] As a further embodiment of this utility model: the first inner core is provided with a post, the second inner core is provided with a slot, the reinforcing clip is provided with a through hole, and the post can pass through the through hole and be inserted into the slot.

[0011] As a further aspect of this utility model: multiple slots are formed on both the first inner core and the second inner core.

[0012] As a further embodiment of this utility model: a positioning post is provided on the electrical contact surface.

[0013] Compared with the prior art, the beneficial effects of this technical solution are as follows: the first terminal and the second terminal are integrated with the first inner core and the second inner core through pre-embedded injection molding process, respectively, to ensure the stability of the structure during long-term insertion and removal. The reinforcing clip is clamped in the first inner core and the second inner core. At the same time, the core and the first inner core and the second inner core are integrated with the first inner core and the second inner core through secondary injection molding. The reinforcing clip forms a mechanical skeleton inside, which improves the overall structural rigidity and allows the connector to withstand greater insertion and removal force and lateral stress, thereby improving the insertion and removal life and durability of the connector. The integrated design of the core and the first inner core and the second inner core makes the dimensional stability better. Compared with the traditional assembled structure, it eliminates the risk of loosening, structural separation or deformation that may occur after being subjected to force. The second outer shell and the main shell form a double-shell structure, which improves the overall structural strength of the connector, enhances its impact resistance, and prevents the shape of the internal interface from being affected by the deformation of the external structure, thus ensuring the long-term stability of signal transmission and the overall service life of the connector.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 A Type-C connector with a built-in reinforcement structure includes a main housing 1, a core 2, a first inner core 3, a second inner core 4, and conductive terminals 5; The core 2 is provided with a rubber block 21 and a tongue plate 22. The lower end of the rubber block 21 is provided with a contact surface 23. The rubber block 21 is fastened by the main housing 1. The tongue plate 22 extends into the interior of the main housing 1. The conductive terminal 5 includes a first terminal 51 and a second terminal 52, and the first terminal 51 and the second terminal 52 are integrally formed with the first inner core 3 and the second inner core 4 through a pre-embedded injection molding process. A reinforcing clip 6 is sandwiched between the first inner core 3 and the second inner core 4; After the first inner core 3, the second inner core 4 and the reinforcing clip 6 are assembled, a second injection molding process is performed to form the rubber core 2 on the outside of the first inner core 3, the second inner core 4 and the reinforcing clip 6, forming an integrated structure.

[0019] Specifically, the first terminal 51 and the second terminal 52 are integrated with the first inner core 3 and the second inner core 4 through a pre-embedded injection molding process, ensuring structural stability during long-term insertion and removal. The reinforcing clip 6 is clamped inside the first inner core 3 and the second inner core 4. At the same time, the core 2 is integrated with the first inner core 3 and the second inner core 4 through secondary injection molding. The reinforcing clip 6 forms a mechanical skeleton inside, improving the overall structural rigidity and allowing the connector to withstand greater insertion and removal forces and lateral stress, thereby improving the connector's insertion and removal life and durability. The integrated design of the core 2 with the first inner core 3 and the second inner core 4 makes the dimensional stability better. Compared with the traditional assembled structure, it eliminates the risk of loosening, structural separation or deformation that may occur after being subjected to force.

[0020] Preferably, after the core 2 is formed on the outside of the first inner core 3, the second inner core 4 and the reinforcing clip 6 by secondary injection molding, the first terminal 51 and the second terminal 52 are both formed with welding feet 7 that protrude through the contact surface 23.

[0021] Specifically, the pre-embedded injection molding and secondary injection molding make the first terminal 51 and the second terminal 52 fit tightly with the first inner core 3 and the second inner core 4, and protrude from the contact surface 23 of the core 2, providing an interface for reliable soldering with the external PCB board. The first terminal 51 and the second terminal 52 protrude from the surface of the tongue plate 22 in the final product, and make contact and conduct electricity when the external plug is inserted.

[0022] Based on the above embodiments, it is further proposed that a second outer shell 8 is provided outside the main shell 1, and the lower ends of the second outer shell 8 are provided with locking feet 81.

[0023] Specifically, a second outer shell 8 is fitted over the main shell 1. The insertion pins on both sides of the lower end of the second outer shell 8 can be inserted into the corresponding holes on the PCB board when the connector is installed, so as to play the role of precise pre-positioning and mechanical anchoring, and provide a guarantee for the subsequent soldering process. The second outer shell 8 and the main shell 1 form a double-shell structure, which improves the overall structural strength of the connector, enhances the connector's impact resistance, and prevents the shape of the internal interface from being affected by the deformation of the external structure, thus ensuring the long-term stability of signal transmission and the overall service life of the connector.

[0024] Based on the above embodiments, it is further proposed that after the first inner core 3 and the second inner core 4 are assembled, a clamping groove 9 is formed inside, and the clamping groove 9 is opened according to the outer contour of the reinforcing clip 6.

[0025] Specifically, the clamping groove 9 is formed by a precision mold on the opposite surface of the first inner core 3 and the second inner core, creating a cavity that matches the outer contour of the reinforcing clip 6. When the first inner core 3 and the second inner core 4 are aligned, the clamping groove 9 forms a space for accommodating and limiting the reinforcing clip 6, ensuring that the reinforcing clip 6 will not be displaced or deformed during subsequent processing, so that it can be precisely fixed in the predetermined position, ensuring that it plays a role in improving the overall structural rigidity after the product is manufactured. The clamping groove 9 is composed of the opposite surfaces of the first inner core 3 and the second inner core 4. That is, a half groove is opened on the opposite surfaces of the first inner core 3 and the second inner core 4. When the first inner core 3 and the second inner core 4 are aligned, the two half grooves form a complete clamping groove 9.

[0026] Based on the above embodiments, it is further proposed that the first inner core 3 is provided with a post 31, the second inner core 4 is provided with a slot 41, the reinforcing clip 6 is provided with a through hole 61, and the post 31 can pass through the through hole 61 and be inserted into the slot 41.

[0027] Specifically, during the assembly process, the reinforcing clip 6 can be placed on the first inner core 3, and the insert post 31 can be inserted into the through hole 61. At the same time, the reinforcing clip 6 is also located in the clamping groove 9 to achieve the positioning of the reinforcing clip 6. Then, the slot 41 of the second inner core 4 is aligned with the insert post 31 for insertion, so as to achieve precise positioning of the first inner core 3, the second inner core 4 and the reinforcing clip 6, prevent misalignment, and form a pre-assembled stable body through mechanical interlocking, so as to facilitate subsequent processing and maintain a high level of production precision.

[0028] Based on the above embodiments, it is further proposed that multiple slots 10 are formed on both the first inner core 3 and the second inner core 4.

[0029] Specifically, the groove 10 consists of multiple grooves and holes formed on the first inner core 3 and the second inner core 4. Its main function is that during secondary injection molding, when the core 2 is formed on the outside, its molten raw material will be injected into the groove 10. After cooling and solidification, it forms a mechanical interlocking structure, which enhances the bonding force and tensile strength between the core 2 and the first inner core 3 and the second inner core 4, prevents the core 2 from loosening and separating from the first inner core 3 and the second inner core 4, and ensures the structural integrity of the product.

[0030] Based on the above embodiments, it is further proposed that a positioning post 24 is provided on the power contact surface 23; when the connector is soldered to the PCB board, the positioning post 24 can be pre-inserted into the corresponding positioning hole on the PCB board to achieve precise pre-positioning of the connector and the PCB board, ensuring that the soldering pin 7 can be accurately aligned with the corresponding soldering point, and preventing cold solder joints caused by component movement during the soldering process.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
