Description

Technical Field

[0001] This utility model relates to the field of TYPE-C connectors, and in particular to a TYPE-C connector structure. Background Technology

[0002] With the continuous development of society and the electronics industry, connectors, also known domestically as plugs, sockets, or connectors, generally refer to electrical connectors. They are devices that connect two active devices, allowing current or signals to flow from one conductor to another. Simply put, electronic connectors are components used to complete electrical connections between circuits or electronic devices, thus becoming a bridge between them. Connector forms and structures are ever-changing. Depending on the application, frequency, power, and application environment, there are various types of connectors. The components that connect the circuit on all connectors are the contacts, or contact terminals.

[0003] Currently, due to the requirements of fast charging for mobile portable devices, TYPEC connectors are required to allow increasingly larger currents. If there are connecting gaps between terminals or between terminals and latches inside the connector, and liquid accumulates in these gaps due to environmental or usage effects, electrical problems such as short circuits and withstand voltage issues caused by ion migration will occur when a large current passes through. To solve this problem, the current solution is to insert rubber plugs into the terminals and then use an insert molding process to completely encapsulate them to eliminate the connecting gaps inside the connector (such as the composition of the insert molding assembly).

[0004] However, the existing TYPE-C connector insert molding assembly does not provide good positioning within the core. Furthermore, the upper and lower rubber walls of the core positioning insert molding assembly are not connected, resulting in insufficient positioning. This affects the height of the terminal contacts and makes mass production difficult.

[0005] Furthermore, during the insert molding process, the plastic flow passing through the adjacent area of ​​the hook positioning groove on the insulating base will impact the hook positioning groove, causing it to tilt. This tilted hook positioning groove will cause the hooks on the assembly to tilt as well. Consequently, when the tilted hooks pass through the IR oven during the SMT process, the plastic core will soften due to the high temperature, causing the plastic core to tilt as well, thus affecting the height instability of the terminal contacts.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0007] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a TYPE-C connector structure that utilizes the matching connection of positioning pins and positioning holes to achieve assembly positioning between the insulating base and the core. With the addition of a support part, on the one hand, it facilitates the connection and positioning of the core to the insulating base and terminals, ensuring the high stability of the terminal contacts; on the other hand, it improves the structural strength of the core, making assembly convenient, positioning accurate, and conducive to improving product production efficiency and having a wide range of applications.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0038] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0039] A TYPE-C connector structure includes a housing 11, an insulating base 12, terminals 13, and a core 14. The terminals 13 are disposed on the insulating base 12 and have a contact section 131 exposed at the front end of the insulating base 12. The insulating base 12 is assembled onto the core 14 and forms a mating cavity 15 with a front opening. The contact section 131 of the terminals 13 is located on the mating cavity 15. The core 14 has a positioning portion 141 for contacting and positioning with the insulating base. The insulating base 12 has a positioning post 121 extending toward the positioning portion. The positioning portion 141 has a positioning hole 142, and the positioning post 121 is adapted to the positioning hole 142. The core 14 has an integrally formed connector. Support portions 143 are attached to the upper and lower walls of the core. The support portions 143 are located in front of the insulating base 12 and beside the positioning portion 141. A clearance area for terminals to pass through is formed between adjacent support portions 143 and positioning portions 141. The outer shell 11 is disposed on the outside of the core 14. In this way, the mutual matching connection of the positioning post and the positioning hole is used to realize the assembly positioning between the insulating base and the core. With the setting of the support portion, on the one hand, it facilitates the connection and positioning of the core to the insulating base and the terminal, ensuring the high stability of the terminal contact. On the other hand, it improves the structural strength of the core. The structure is ingenious and reasonable, easy to assemble, and accurate in positioning, which is conducive to improving the production efficiency of the product, with good stability in use and a wide range of applications.

[0040] In this embodiment, three positioning parts 141 and three support parts 143 are provided. The three positioning parts 141 are arranged at intervals on the left and right. Among the three support parts 143, one support part 143 is located to the right of the positioning part 141 located on the right, and the other two support parts 143 are located to the left and right of the positioning part 141 located on the left, respectively. Correspondingly, three positioning posts 121 are provided.

[0041] Specifically, the positioning holes 142 of the positioning parts 141 on the left and right sides are at the same height, and the positioning hole 142 of the positioning part 141 in the middle is at a height greater than or less than the positioning holes 142 of the positioning parts 141 on the left and right sides. Correspondingly, the height of the positioning pins 121 on the left and right sides is equal to the height of the positioning holes 142 of the positioning parts 141 on the left and right sides, and the height of the positioning pin 121 in the middle is equal to the height of the positioning hole 142 of the positioning part 141 in the middle. Preferably, the height of the positioning hole 142 of the middle positioning part 141 is greater than the positioning holes 142 on both sides, and the height of the positioning pin 121 in the middle is greater than the positioning pins 121 on both sides. In this way, the height of the middle positioning hole and positioning pin is not the same as that of the positioning holes and positioning pins on the left and right sides, so as to realize the foolproof assembly between the insulating seat and the glue core, thereby ensuring the stable and consistent quality of the product and its good usability.

[0042] Furthermore, the terminal 13 has a connecting section 132, and the insulating base 12 is provided with a cavity 122 corresponding to the connecting section. The cavity 122 is provided with an insert molding part 16 by insert molding, and part of the connecting section 122 is disposed inside the insert molding part 16.

The insulating base 12 is provided with a connecting groove 123 that matches the connecting part. The connecting groove 123 is located on the rear side of the cavity 122. The connecting part 171 is adapted and positioned on the connecting groove 123.

[0044] Specifically, the upper and lower ends of the insulating base 12 are provided with reinforcing parts 124 corresponding to the connecting groove, which improves the structural strength of the connecting groove in the insulating base, avoids the impact of the insert molding part on the connecting groove during molding, and prevents the connecting part of the hook from deforming. This improves the stability of the hook in the product and is conducive to the height stability of the terminal contact, making it highly practical.

[0045] Furthermore, the insulating base 12 is provided with a locking block 125 for engaging with the rubber core, and the outer side of the rubber core 14 is provided with a matching locking block groove 144. The locking block 125 is adapted to the locking groove 144 to form an assembly connection between the insulating base 12 and the rubber core 14. Preferably, the positioning part 141 is provided with a first guide slope 145 communicating with the positioning hole, the rear end of the support part 143 is provided with a second guide slope 146, and the locking block 125 is provided with a third guide slope 126. Thus, the first guide slope is provided to guide the positioning post into the positioning hole, and the second guide slope is provided to guide the contact section of the terminal into the insertion cavity when the insulating base and the rubber core are assembled. At the same time, the third guide slope is provided to facilitate the assembly connection between the locking block and the locking groove.

[0046] The key design feature of this utility model lies in the fact that it utilizes the matching connection of positioning posts and positioning holes to achieve the assembly and positioning between the insulating base and the rubber core through the design of each component. With the support part, on the one hand, it facilitates the connection and positioning of the rubber core to the insulating base and terminals, ensuring the high stability of the terminal contacts. On the other hand, it improves the structural strength of the rubber core. The structure is ingenious and reasonable, easy to assemble, and accurately positioned, which helps to improve the production efficiency of the product, has good stability in use, and has a wide range of applications.

[0047] Secondly, the height of the middle positioning hole and positioning post is different from that of the left and right positioning holes and positioning posts to achieve foolproof assembly between the insulating base and the rubber core, thereby ensuring stable and consistent product quality and good usability. At the same time, the first guide slope is set to facilitate the positioning post to be guided into the positioning hole, and the second guide slope is set to facilitate the terminal contact section to be guided into the insertion cavity when the insulating base and the rubber core are assembled.

[0048] Furthermore, the reinforcement enhances the structural strength of the connecting groove within the insulating base, preventing the insert molding part from affecting the connecting groove and causing deformation of the hook's connecting part. This improves the stability of the hook in product use, contributes to the height stability of the terminal contacts, and enhances its practicality.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
