Almost all external devices have a USB interface, making it extremely widely used. Type-C is a USB connector that can be inserted either way, measuring approximately 8.3mm x 2.5mm. Like other connectors, it supports standard USB functions such as charging, data transfer, and display output.

[0003] A Chinese utility model patent with authorization announcement number CN219626946U discloses a Type-C terminal plastic molded part and a Type-C connector, wherein the terminal plastic molded part includes an upper row of terminal modules, a metal grounding plate, and a lower row of terminal modules stacked in sequence from top to bottom. The upper row of terminal modules, the metal grounding plate, and the lower row of terminal modules constitute a terminal plastic molded part combination.

[0004] Specifically, the manufacturing method of the Type-C terminal plastic molding is as follows: S1. Several upper-row terminals are injection-molded into an upper-row terminal module with an upper-row insulator through a first mold; S2. A metal grounding plate is produced using a second mold; S3. Several lower-row terminals are injection-molded into a lower-row terminal module with a lower-row insulator through a third mold; S4. The upper-row terminal module, the metal grounding plate, and the lower-row terminal module are stacked in a fourth mold from top to bottom to form a terminal plastic molding combination.

[0005] However, the above method for manufacturing the terminal plastic molding part of Type-C can only manufacture one terminal plastic molding part at a time, with low working efficiency and being unfavorable for improving productivity. Among them, during the production process, the excess metal materials on the upper row terminals, lower row terminals, and metal grounding sheet are all cut off, and then the upper row terminals and lower row terminals are respectively placed into the corresponding molds to form the upper row insulating parts and lower row insulating parts, so as to manufacture the upper row terminal module and lower row terminal module. Then, when assembling the upper row terminal module, metal grounding sheet, and lower row terminal module and placing them into the fourth mold, it is also necessary to add positioning for positioning, which increases the complexity of the fourth mold and the mold cost. Then, plastic can be molded to form the terminal plastic molding part combination.

[0022] The following further describes the utility model in conjunction with specific embodiments and drawings.

[0023] See Figure 1-4 As shown, it is a Type-C connector module with efficient stamping and injection molding, which includes: an upper terminal module assembly 100, a lower terminal module assembly 400, a middle iron sheet assembly 700, and four plastic seats 9. The upper terminal module assembly 100, the middle iron sheet assembly 700, and the upper terminal module assembly 100 are sequentially laminated, fitted, and positioned for assembly, and four plastic seats 9 are integrally formed on the upper terminal module assembly 100, the middle iron sheet assembly 700, and the upper terminal module assembly 100 to form four terminal plastic molded parts.

[0024] The specific structure is as follows:

[0025] The upper terminal module assembly 100 includes a first material rack 1 in a king shape, four groups of upper terminal groups 2 distributed in a square shape and corresponding to the first material rack 1, and four upper insulators 3 respectively formed on the upper terminal groups 2 in a one-to-one correspondence. An upper terminal group 2 and an upper insulator 3 form an upper terminal module. One end of the first middle material belt 11 in the middle of the first material rack 1 is connected to two groups of the upper terminal groups 2 respectively on both sides, and the other end of the first middle material belt 11 is connected to two groups of the upper terminal groups 2 respectively on both sides, and a number of first positioning holes 111 are provided on the first middle material belt 11; the lower terminal module assembly 400 includes a second material rack 4 in a king shape and corresponding to the first material rack 1, four groups of lower terminal groups 5 distributed in a square shape and corresponding to the second material rack 4, and four lower insulators 6 respectively formed on the lower terminal groups 5 in a one-to-one correspondence. A lower terminal group 5 and a lower insulator 6 form a lower terminal module. One end of the second middle material belt 41 in the middle of the second material rack 4 is connected to two groups of the lower terminal groups 5 respectively on both sides, and the other end of the second middle material belt 41 is connected to two groups of the lower terminal groups 5 respectively on both sides, and a number of second positioning holes 411 corresponding to the first positioning holes 111 are provided on the second middle material belt 41; the middle iron sheet assembly 700 includes a third material rack 8 formed by stamping a metal sheet and four middle iron sheets 7 integrally connected to the second material rack 4 and distributed in a square shape. The third material rack 8 is provided with third positioning holes 81 corresponding to the first and second positioning holes; the upper terminal module assembly 100, the middle iron sheet assembly 700, and the lower terminal module assembly 400 are sequentially laminated and assembled by embedding and positioning, wherein the first, third, and second material racks are laminated in sequence, and the upper and lower terminal modules clamp and fix the middle iron sheet 7; four plastic seats 9 are respectively formed on the upper and lower terminal modules to form four terminal plastic molding parts.That is to say, for the Type-C connector module with high-efficiency stamping and injection molding of the present utility model, four upper terminal modules are first fabricated on a first rack 1 in a king-shaped configuration. When the first rack 1 is placed in the first mold, it is fixed to the first mold by the first positioning holes 111 to ensure better quality of the upper terminal modules fabricated later, and there is no ineffective additional structural positioning between them to simplify the first mold. Then, a third rack 8 and four middle iron sheets 7 integrally connected to the second rack 4 and distributed in a square shape are formed by stamping a metal sheet. Next, four lower terminal modules are fabricated on a second rack 4 in a king-shaped configuration. When the second rack 4 is placed in the second mold, it is fixed to the second mold by the second positioning holes 411 to ensure better quality of the lower terminal modules fabricated later, and there is no ineffective additional structural positioning between them to simplify the second mold. Then, the first rack 1 and the second rack 4 are clamped and fitted to the upper and lower ends of the third rack 8, and the upper and lower terminal modules clamp and fix the middle iron sheets 7, and they are placed in the third mold. The first, second, and third positioning holes corresponding to each other are simultaneously positioned with the third mold, and there is no ineffective additional structural positioning between them, making the structure of the third mold simpler. Finally, four plastic seats 9 are injection-molded to fabricate four terminal plastic molded parts with higher quality, enabling the present utility model to fabricate four terminal plastic molded parts at one time, with high working efficiency and conducive to improving productivity. When specifically used, the first rack 1, the second rack 4, and the third rack 8 are cut and separated from the four terminal plastic molded parts to form four independent terminal plastic molded parts.

[0026] One end of the upper terminal group 2 connected to the first rack 1 is provided with a first pre-breaking groove 201; one end of the lower terminal group 5 connected to the second rack 4 is provided with a second pre-breaking groove 501. The first pre-breaking groove 201 and the second pre-breaking groove 501 are distributed in an upper and lower projection, so that when the terminal plastic molded part is broken relative to the first rack 1 and the second rack 4 later, the breaking work of the first rack 1 and the second rack 4 can be completed at one time, with simpler, more convenient operation and higher efficiency.

[0027] The other end of the upper terminal group 2 connected to the first material rack 1 is also integrally connected with the first material strip 21; the other end of the lower terminal group 5 connected to the second material rack 4 is also integrally connected with the second material strip 51, wherein the end of the second material strip 51 connected to the lower terminal group 5 is also formed with an upwardly bent bending bridge 511, and the bending bridge 511 is integrally connected to the lower terminal group 5; the other end of the upper terminal group 2 connected to the first material rack 1 and the other end of the lower terminal group 5 connected to the second material rack 4 are staggered and distributed in the same plane, and are distributed in a straight line, and the first material strip 21 and the second material strip 51 are overlapped and assembled, so that the upper terminal group 2 and the lower terminal group 5 can be in the best position, which is convenient for improving the quality of the terminal plastic molding made later. At the same time, it can also increase the assembly structure stability and accuracy between the upper terminal module assembly 100, the middle iron sheet assembly 700, and the lower terminal module assembly 400. After the terminal plastic molding is formed, the first strip 21 and the second strip 51 are cut at once relative to the upper terminal assembly 2 and the lower terminal assembly 5, which is simpler and more efficient. When cutting the second strip 51, the portion connecting the bent bridge 511 and the lower terminal assembly 5 is cut.

[0028] The first material strip 21 and the second material strip 51 have the same shape and size, so that after the first material strip 21 and the second material strip 51 are overlapped, they will not take up too much space, which is convenient for the design of the third mold.

[0029] Any two of the four terminal plastic moldings are mirror-symmetrical.

[0030] The third material rack 8 is distributed in a W-shaped shape, and is distributed perpendicularly to the first material rack 1 and the second material rack 4 in a W-shaped shape, so that the third material rack 8 can be better assembled with the first material rack 1 and the second material rack 4, and the middle part of the third material rack 8 fits the first middle material belt 11 and the second middle material belt 41, and is clamped and fixed by the first middle material belt 11 and the second middle material belt 41, and its assembly structure is more stable.

[0031] The third material rack 8 has four slots 82, each of which is formed with two third sub-material bridges 83. The two third sub-material bridges 83 are respectively connected to the two sides of the middle iron sheet 7 as a whole, so as to ensure that the middle iron sheet 7 is stably connected to the third material rack 8, so that it can be better assembled with the upper and lower terminal modules in the later stage; and the third sub-material bridge 83 is in the shape of a spike with one end large and the other end small, which can be better cut off, or cut off more easily, which can further improve the assembly efficiency.

[0032] At both ends of the front end of the first material rack 1, a third material belt 12 and a fourth material belt 13 are respectively formed. The third material belt 12 and the fourth material belt 13 are both provided with fourth positioning holes 101; at both ends of the front end of the second material rack 4, a fifth material belt 42 and a sixth material belt 43 are respectively formed. The fifth material belt 42 and the sixth material belt 43 are both provided with fifth positioning holes 401. The third material belt 12 and the fourth material belt 13 are respectively assembled corresponding to the fifth material belt 42 and the sixth material belt 43. Among them, there is a gap formed between them. The fourth positioning hole 101 corresponds to the fifth positioning hole 401, which can better laminate and embed and position-assemble the upper terminal module assembly 100, the middle iron sheet assembly 700, and the lower terminal module assembly 400 in sequence. The fourth positioning hole 101 and the fifth positioning hole 401 are also convenient for positioning with the third mold when forming the plastic seat, so as to ensure a more stable structure and higher quality of the formed terminal plastic molding part.

[0033] Both the left and right sides of the third material belt 12 protrude beyond the left and right sides of the fifth material belt 42, and both the left and right sides of the sixth material belt 43 protrude beyond the left and right sides of the fourth material belt 13. This assembly structure is convenient for adjusting the relative positions of the first material rack 1 and the second material rack 4, and is also convenient for separating the two from each other later.

[0034] In summary, the Type-C connector module of the present utility model for high-efficiency stamping and injection molding first makes four upper terminal modules on a first material rack 1 in a king shape. Among them, when the first material rack 1 is placed in the first mold, it is fixed to the first mold by the first positioning hole 111 to ensure better quality of the upper terminal module made later, and there is no ineffective additional structure positioning between them to simplify the first mold; then the third material rack 8 and four middle iron sheets 7 integrally connected to the second material rack 4 and distributed in a cross shape are formed by metal sheet stamping; then four lower terminal modules are made on a second material rack 4 in a king shape. Among them, when the second material rack 4 is placed in the second mold, it is fixed to the second mold by the second positioning hole 411 to ensure better quality of the lower terminal module made later, and there is no ineffective additional structure positioning between them to simplify the second mold; then the first material rack 1 and the second material rack 4 are clamped and laminated on the upper and lower ends of the third material rack 8, and the upper and lower terminal modules clamp and fix the middle iron sheet 7, and are placed in the third mold. The first, second, and third positioning holes corresponding to each other are simultaneously positioned with the third mold, and there is no ineffective additional structure positioning between them, making the structure of the third mold simpler. Finally, four plastic seats 9 are injection-molded to make four terminal plastic molding parts with higher quality, so that the present utility model can realize making four terminal plastic molding parts at one time, with high working efficiency and conducive to improving productivity.
