Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a Type-c-24p double-stick connector. Background Art

[0002] In the field of electronic device connectivity, Type-C connectors are widely used due to their high transmission speeds and excellent compatibility. Traditional Type-C connectors consist of an insulator, terminals mounted within the insulator, and a metal housing encasing the insulator. The metal housing is typically mounted to the connector body using simple snap-on or screw fastening.

[0003] However, these fixing methods have many drawbacks. For example, the snap-on fixing method may loosen due to long-term use or external forces, which may affect the electrical performance and stability of the connector. While the screw fixing method is relatively secure, the installation process is cumbersome and requires additional screws and installation tools, increasing production costs and installation difficulty. Therefore, a Type-C-24P double-stick connector is provided to address the above technical issues. Utility Model Content

[0004] The purpose of the present invention is to provide a Type-c-24p double-stick connector to address the shortcomings of the existing technology and solve the technical problem of unstable installation of the metal shell on the existing connector.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] The Type-C-24P double-stick connector includes a first inner core and a second inner core stacked on top of each other, with a metal sheet disposed between the first inner core and the second inner core. The stacked first inner core and the second inner core are injection molded into a main body, so that the first inner core, the metal sheet, and the second inner core are solidified into one body.

[0007] The main body includes a mounting portion and a flat tongue portion, the mounting portion is provided with a metal shell, and both sides of the metal shell are integrally formed with a mounting plate, and the mounting plate is formed with a mounting hole;

[0008] A snap-fitting recess is formed at the bottom of the mounting portion, and a snap-fitting leg is formed on the metal shell and bent in an L shape and snapped into the snap-fitting recess; the metal shell also has a fitting opening, and the mounting portion has an insert embedded in the fitting opening.

[0009] Furthermore, a socket is formed on the top surface of the mounting portion, and a plug-in portion inserted into the socket is formed on the metal shell.

[0010] Furthermore, the metal shell is integrally formed with an extension portion for blocking the rear end of the mounting portion.

[0011] Furthermore, the first inner core includes a plurality of upper terminals that are separated and arranged in parallel, and an upper body that is injection molded outside the plurality of upper terminals and is flat, and both ends of the plurality of upper terminals pass through the upper body; the second inner core includes a plurality of lower terminals that are separated and arranged in parallel, and a lower body that is injection molded outside the plurality of lower terminals and is flat, and both ends of the plurality of lower terminals pass through the lower body; the front end portions of the plurality of upper terminals are bent and embedded in the tongue and the side portions protrude from the top surface of the tongue, and the front end portions of the plurality of lower terminals are bent and embedded in the tongue and the side portions protrude from the bottom surface of the tongue.

[0012] Furthermore, the plurality of upper terminals and the plurality of lower terminals are arranged in two rows, and the rear ends of the plurality of upper terminals and the plurality of lower terminals pass through the mounting portion and are bent and arranged horizontally on the same plane.

[0013] Furthermore, a mutually plugged positioning structure is provided between the upper body and the lower body.

[0014] Furthermore, the positioning structure includes a plurality of second positioning columns arranged on the lower body and extending upward, and a plurality of first positioning columns arranged on the upper body and extending downward. The upper body is formed with a plurality of first positioning holes for inserting the second positioning columns, and the lower body is formed with a plurality of second positioning holes for inserting the first positioning columns.

[0015] Furthermore, a plurality of first protrusions are formed on the top surface of the upper body, and a plurality of second protrusions are formed on the bottom surface of the lower body.

[0016] Furthermore, the lower body is formed with a plurality of limiting protrusions, and a limiting groove for limiting a single upper terminal is formed between two adjacent limiting protrusions.

[0017] Furthermore, the metal sheet is formed with a plurality of through holes for the second positioning posts and / or the first positioning posts to pass through, and is also formed with pins to pass through the mounting portion.

[0018] Beneficial effects of the utility model:

[0019] During manufacturing, the stacked first and second cores are injection molded into the main body. The metal sheet is positioned between the first and second cores, thus integrating the first, metal sheet, and second cores into a single unit. The metal housing is then mounted on the mounting portion of the main body, completing the connector. This injection molding process not only improves the connector's production efficiency but also enhances its structural strength, making it less susceptible to damage.

[0020] 2. When the connector needs to be installed on a peripheral circuit board, stick the plate to the designated mounting position on the circuit board, and then fix the plate to the circuit board with screws to complete the installation of the connector; by setting the plates on both sides of the metal shell and fixing them with screws, it is not only easy to install, but also makes the installation stable.

[0033] The following is a detailed description of the Type-c-24p double-stick connector of the present invention with reference to the accompanying drawings.

[0034] like Figure 1-5As shown, an embodiment of the Type-c-24p double-stick connector of the present invention includes a first inner core 1 and a second inner core 2 stacked on each other, a metal sheet 3 is provided between the first inner core 1 and the second inner core 2, and the stacked first inner core 1 and the second inner core 2 are injection molded with a main body 4, so that the first inner core 1, the metal sheet 3 and the second inner core 2 are solidified into one. The injection molding production method not only improves the production efficiency of the connector, but also improves the structural strength of the connector itself, making it not easy to be damaged.

[0035] Furthermore, the first inner core 1 includes a plurality of upper terminals 11 arranged in parallel and separated, and an upper body 12 which is injection molded outside the plurality of upper terminals 11 and is flat, and both ends of the plurality of upper terminals 11 pass through the outer side of the upper body 12; when manufacturing the first inner core 1, the plurality of upper terminals 11 are first arranged, and then the upper body 12 is injection molded on the arranged plurality of upper terminals 11 to form a Figure 3 The first inner core 1 shown here has completed the first step of the injection molding process for manufacturing the connector.

[0036] The second inner core 2 includes a plurality of lower terminals 21 arranged in parallel and separated, and a flat lower body 22 which is injection-molded outside the plurality of lower terminals 21. Both ends of the plurality of lower terminals 21 extend out of the lower body 22. When manufacturing the second inner core 2, the plurality of lower terminals 21 are first arranged, and then the lower body 22 is injection-molded on the arranged plurality of lower terminals 21 to form a Figure 3 The second inner core 2 shown here has completed the second injection molding process for manufacturing the connector.

[0037] After the first inner core 1 and the second inner core 2 are manufactured, the first inner core 1 and the second inner core 2 are stacked and the metal sheet 3 is placed in the middle. Finally, the main body 4 is injection molded to fuse the first inner core 1, the metal sheet 3 and the second inner core 2 into a whole. Figure 1 The structure shown in FIG. 1 has now completed the third injection molding process for manufacturing the connector.

[0038] The main body 4 includes a mounting portion 42 and a flat tongue portion 41. The front ends of the multiple upper terminals 11 are bent and embedded in the tongue portion 41, and the side portions protrude from the top surface of the tongue portion 41. The front ends of the multiple lower terminals 21 are bent and embedded in the tongue portion 41, and the side portions protrude from the bottom surface of the tongue portion 41. The multiple upper terminals 11 and the multiple lower terminals 21 are arranged in two rows, one above the other, and the rear ends of the multiple upper terminals 11 and the multiple lower terminals 21 pass through the mounting portion 42 and are bent and arranged horizontally in the same plane. When the connector is installed on an external circuit board, it is convenient to weld the rear ends in the same plane to the external circuit board.

[0039] In addition, a metal shell 5 is mounted on the mounting portion 42 to stably mount the connector on the peripheral circuit board. The specific manufacturing process of the connector is as follows: First, the upper body 12 is formed by injection molding the arranged plurality of upper terminals 11. Figure 3 The first inner core 1 shown in FIG. 1 is formed by injection molding a lower body 22 on a plurality of arranged lower terminals 21. Figure 3 The second inner core 2 is shown, and then the first inner core 1 and the second inner core 2 are stacked and the metal sheet 3 is placed in the middle, and the main body 4 is injection molded so that the first inner core 1, the metal sheet 3 and the second inner core 2 are integrated into a whole. Figure 1 The structure shown is then installed on the mounting portion 42 of the main body 4 to complete the manufacture of the Type-c-24p double-stick connector (24p means 24pin, representing 24 terminals). Compared with the prior art, different modules are injection molded in three steps to facilitate terminal arrangement and positioning as well as automated production. Moreover, the manufactured connector product is thinner, with an optimal total thickness of 1.95mm. There are floating errors in the actual processing process, and the error is within the qualified range of the product. The thickness can vary according to the requirements of different processing procedures or different models.

[0040] After the connector is manufactured, in order to further improve the quality and structural strength of the connector, a mutually interlocking positioning structure is provided between the upper body 12 and the lower body 22. The positioning structure includes a plurality of second positioning posts 24 disposed on the lower body 22 and extending upward, and a plurality of first positioning posts 15 disposed on the upper body 12 and extending downward. The upper body 12 is formed with a plurality of first positioning holes 14 for inserting the second positioning posts 24, and the lower body 22 is formed with a plurality of second positioning holes 25 for inserting the first positioning posts 15. After the upper body 12 and the lower body 22 are stacked, the second positioning posts 24 are inserted into the first positioning holes 14, and the first positioning posts 15 are inserted into the second positioning holes 25. Furthermore, the metal sheet 3 is disposed between the upper body 12 and the lower body 22. The upper body 12 and the lower body 22 are then injection molded into the main body 4. The positioning structure improves the structural strength between the upper body 12 and the lower body 22.

[0041] In this embodiment, a plurality of first protrusions 13 are formed on the top surface of the upper body 12, and a plurality of second protrusions 23 are formed on the bottom surface of the lower body 22. By providing the first protrusions 13 and the second protrusions 23, the structural strength between the upper body 12, the lower body 22 and the main body 4 is improved after the main body 4 is injection molded.

[0042] Additionally, the lower body 22 is formed with a plurality of limiting protrusions 26, with a limiting groove formed between adjacent limiting protrusions 26 for limiting the position of a single upper terminal 11. When the upper body 12 and the lower body 22 are stacked, the multiple upper terminals 11 and the multiple lower terminals 21 are arranged in two rows, one above the other. Therefore, the multiple upper terminals 11 are placed in different limiting grooves to prevent the multiple upper terminals 11 from shifting and deforming during injection molding of the main body 4.

[0043] The metal sheet 3 is formed with a plurality of through-holes 31 for the second positioning posts 24 or the first positioning posts 15 to pass through. When the second positioning posts 24 are inserted into the first positioning holes 14 or the first positioning posts 15 are inserted into the second positioning holes 25, they pass through the through-holes 31, thereby stably positioning the metal sheet 3 between the upper body 12 and the lower body 22. Furthermore, the metal sheet 3 is formed with pins 32 that extend through the mounting portion 42 and are used for soldering to an external circuit board. The pins 32 extend downward to facilitate contact with the external circuit board.

[0044] In order to stably mount the metal shell 5 on the mounting portion 42 of the main body 4, a snap-fitting recess 45 is formed at the bottom of the mounting portion 42. The metal shell 5 is formed with a snap-fitting foot 53 bent in an L shape and snapped into the snap-fitting recess 45. By snapping the snap-fitting foot 53 into the snap-fitting recess 45, the metal shell 5 cannot move up or down after being mounted on the mounting portion 42. The metal shell 5 also has a mating opening 51. The mounting portion 42 is formed with an insert 43 that fits into the mating opening 51 from bottom to top. When the metal shell 5 is mounted on the mounting portion 42 from top to bottom, the insert 43 is inserted into the mating opening 51, and the snap-fitting foot 53 is snapped into the snap-fitting recess 45. Under the action of the insert 43 and the mating opening 51, the metal shell 5 cannot move forward or backward after being mounted on the mounting portion 42, thus achieving stable mounting of the metal shell 5.

[0045] Furthermore, a socket 44 is formed on the top surface of the mounting portion 42, and a plug-in portion 52 is formed on the metal shell 5 to be inserted into the socket 44. Before the insert 43 is inserted into the fitting opening 51, the plug-in portion 52 is first inserted into the socket 44, thereby improving the accuracy of installing the metal shell 5.

[0046] In this embodiment, mounting plates 54 are integrally formed on both sides of the metal housing 5 for mounting to the surrounding structure. These plates 54 are formed with mounting holes 55 for screws. To mount the connector on a peripheral circuit board, the mounting plates 54 are affixed to the designated mounting locations on the circuit board and then secured to the board with screws. This completes the installation of the connector. The use of a pair of mounting plates 54 and screws for secure mounting facilitates installation and provides enhanced stability.

[0047] Additionally, the metal housing 5 is integrally formed with an extension 56 that blocks the rear end of the mounting portion 42. When the connector is plugged into a device, the tongue 41 is subjected to force, which is offset by the extension 56, preventing loosening between the mounting portion 42 and the metal housing 5 after repeated use. An annular groove 6 is formed around the base of the tongue 41, housing a sealing ring 7 for sealing against the device, enhancing the connector's seal during use.

[0048] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0049] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
