[0030] Please see Figures 1 to 10 This application discloses a Type-C female connector, including: a first module, a second module, a middle clip 10, and an outer plastic body 20.
[0031] The first module includes a first plastic body 30 and a plurality of first terminals 40 disposed on the first plastic body 30. A first mounting plane 31, a first positioning post 32 protruding from the first mounting plane 31, and a first positioning blind hole 33 formed on the first mounting plane 31 are formed on the upper side of the first plastic body 30. A first injection hole 34 extending through the upper and lower parts of the first plastic body 30 is formed.
[0032] The second module includes a second plastic body 50 and a plurality of second terminals 60 disposed on the second plastic body 50. A second mounting plane 51, a second positioning post 52 protruding from the second mounting plane 51, and a second positioning blind hole 53 formed on the second mounting plane 51 are formed on the lower side of the second plastic body 50. A second injection hole 54 is formed through the upper and lower parts of the second plastic body 50.
[0033] The second module is stacked on the first module, and the first positioning post 32 is adapted to be positioned in the second positioning blind hole 53. The second positioning post 52 is adapted to be positioned in the first positioning blind hole 33. The middle clamp 10 is clamped between the first mounting plane 31 and the second mounting plane 51. The middle clamp 10 has a through-hole 11 and a positioning through-hole 12 that communicate with the through-hole 11. The through-hole 11 communicates with the first injection hole 34 and the second injection hole 54. The first positioning post 32 is located in the through-hole 11 (the first positioning post 32 passes through the through-hole 11 and is adapted to be inserted into the second positioning blind hole 53). The positioning through-hole 12 corresponds to the first positioning blind hole 33 (upper and lower facing each other). The second positioning post 52 is adapted to the positioning through-hole 12 (the second positioning post 52 is adapted to be inserted into the positioning through-hole 12 and the first positioning blind hole 33).
[0034] The outer plastic body 20 is injection molded on the outside of the assembly of the first module, the second module and the middle clip 10. During injection molding, the molten plastic flows in through the first injection hole 34 and the second injection hole 54 and fills the filling groove 11, so that it completely covers the first positioning post 32 and partially covers the second positioning post 52 in the lateral direction. That is, it completely covers the first positioning post 32 in the direction surrounding the first positioning post 32 and partially covers the second positioning post 52 in the direction surrounding the second positioning post 52.
[0035] It should be noted that the first module and the second module mentioned above are not limited to the definitions shown in the attached drawings. The first module can also be defined as the second module, and the second module can also be defined as the first module.
[0036] In this embodiment, a filling groove 11 is formed on the middle clip 10, a first injection hole 34 is formed on the first plastic body 30, and a second injection hole 54 is formed on the second plastic body 50. During injection molding of the outer plastic body 20, molten plastic flows into and fills the filling groove 11 through the first injection hole 34 and the second injection hole 54, thereby completely covering the first positioning post 32 and partially covering the second positioning post 52 laterally. On the one hand, the plastic filled in the filling groove 11 can enhance the bonding strength between the outer plastic body 20, the first plastic body 30, the second plastic body 50, and the middle clip 10. On the other hand, by covering the first positioning post 32 and the second positioning post 52 with plastic, the bonding strength between the outer plastic body 20, the first plastic body 30, the second plastic body 50, and the middle clip 10 can be further enhanced. Moreover, in addition to being partially covered by plastic, the second positioning post 52 can also be positioned and engaged with the positioning hole 12.
[0037] In some embodiments, the first positioning post 32 is located approximately at the center of the filling groove 11 in the front-to-back direction, and the positioning through hole 12 is connected to the rear end of the filling groove 11.
[0038] In some embodiments, a first groove 35 is formed at the front end of the first mounting surface 31 of the first plastic body 30, and the front end of the filling channel 11 communicates with the first groove 35. During injection molding, the plastic is filled into the first groove 35 through the filling channel 11. A second groove 55 is formed at the front end of the second mounting surface 51 of the second plastic body 50, and the front end of the filling channel 11 communicates with the second groove 55. During injection molding, the plastic is filled into the second groove 55 through the filling channel 11.
[0039] When the outer plastic body 20 is injection molded, the plastic is filled through the filling channel 11 into the first groove 35 at the front end of the first plastic body 30 and into the second groove 55 at the front end of the second plastic body 50, so that the plastic can flow to the front end of the first plastic body 30 and the second plastic body 50, which is conducive to further enhancing the bonding strength between the various structures.
[0040] Specifically, the first groove 35 and the second groove 55 are generally U-shaped, with the U-shape having a forward-facing open end.
[0041] Specifically, the rear end of the first groove 35 is vertically opposite to the filling groove 11 (i.e., the rear end of the first groove 35 is connected to the filling groove 11), and the front end of the first groove 35 extends forward beyond the filling groove 11; the rear end of the second groove 55 is vertically opposite to the filling groove 11 (i.e., the rear end of the second groove 55 is connected to the filling groove 11), and the front end of the second groove 55 extends forward beyond the filling groove 11. Because the front ends of the first groove 35 and the second groove 55 extend forward beyond the filling groove 11, this enhances the bonding strength between the front end of the middle clip 10 and the front ends of the first plastic body 30 and the second plastic body 50.
[0042] It should be noted that the fact that the rear end of the first groove 35 is vertically opposite to the filling groove 11, and the rear end of the second groove 55 is vertically opposite to the filling groove 11, means that their projections on the horizontal plane overlap, or that they are connected, but does not mean that they are completely corresponding.
[0043] In some embodiments, the first groove 35 extends forward through the first plastic body 30, and the second groove 55 extends forward through the second plastic body 50. Since the first groove 35 extends forward through the first plastic body 30, and the second groove 55 extends forward through the second plastic body 50, when the outer plastic is injected, the plastic can flow out to the front end through the filling channel 11, the first groove 35, and the second groove 55, which can promote better plastic flow and solve the problem that conventional Type-C female connectors can only be filled from the left and right sides, resulting in narrow channels and difficulty in molding the head (front end).
[0044] In some embodiments, the first positioning post 32 and the second positioning post 52 include a positioning post body 321 / 521 and a plurality of circumferentially distributed ribs 322 / 522 protruding outward from the sidewall of the positioning post body 321 / 521. Due to the arrangement of the ribs 322 / 522 on the first positioning post 32 and the second positioning post 52, the plastic can wrap around the ribs 322 / 522, which can enhance the bonding force between the plastic and the first positioning post 32 and the second positioning post 52. Moreover, since there are spacers between the ribs 322 / 522, the plastic can fill the first positioning blind hole 33 and the second positioning blind hole 53, thereby further enhancing the bonding strength between the structural components.
[0045] In some embodiments, the middle clamp 10 has two glue-filling grooves 11 and two positioning through holes 12. The two glue-filling grooves 11 are arranged side by side and spaced apart in the left-right direction, and the rear end of each glue-filling groove 11 communicates with a positioning through hole 12. There are two first positioning posts 32, each located in one of the two glue-filling grooves 11; there are two second positioning posts 52, each corresponding to one of the two positioning through holes 12. This arrangement facilitates the uniform distribution of bonding force between the structural components. Of course, this arrangement is not a limitation.
[0046] In some embodiments, the first plastic body 30 includes a first base portion 36 and a first rear wall portion 37 connected to the rear end of the first base portion 36. A first mounting plane 31 is formed in the first base portion 36, and the first rear wall portion 37 extends upward beyond the first mounting plane 31. A first injection hole 34 is formed in the first base portion 36, including a front injection hole 341 that is vertically opposite to the filling groove 11 and a rear injection hole 342 located behind the filling groove 11. A recess 311 communicating with the rear injection hole 342 and the filling groove 11 is also formed on the first mounting plane 31. The second plastic body 50 includes a second base portion 56 and a second rear wall portion 57 connected to the rear end of the second base portion 56. The second rear wall portion 57 extends upward beyond the second mounting plane 51. The second plastic body 50 is disposed in relation to the first base portion 36 and is blocked by the first rear wall portion 37. The second injection hole 54 is formed in the second base portion 56 and is vertically opposite to the filling groove 11. The arrangement of the front injection hole 341 and the rear injection hole 342 on the first plastic body 30 and the second injection hole 54 on the second plastic body 50 helps to increase the injection efficiency.
[0047] In some embodiments, the first plastic body 30 includes a first base portion 36 and a first rear wall portion 37 connected to the rear end of the first base portion 36, a first mounting plane 31 is formed in the first base portion 36, the first rear wall portion 37 extends upward beyond the first mounting plane 31, and a plurality of first terminals 40 include a row of first solder pins 41 arranged in a row and extending upward from the first rear wall portion 37; the second plastic body 50 includes a second base portion 56 and a second rear wall portion 57 connected to the rear end of the second base portion 56, the second rear wall portion 57 extends upward beyond the second mounting plane 51, and a plurality of second terminals 60 are included. The second plastic body 50 is assembled with the first base 36 and stopped by the first rear wall 37. The first rear wall 37 and the second rear wall 57 are attached to each other. The upper ends of the first rear wall 37 and the second rear wall 57 together form a boss 357. A number of first welding pins 41 and a number of second welding pins 61 extend upward from the boss 357. When the outer plastic body 20 is injection molded, it is injection molded around the boss 357 and a U-shaped sealing structure 358 is formed between the outer plastic body 20 and the boss 357. Because of the U-shaped sealing structure 358, it can prevent glue from overflowing from the assembly gap of the first plastic body 30, the second plastic body 50 and the middle clip 10 during injection molding of the outer plastic body 20, which would cause burrs and glue overlay problems and affect terminal soldering.
[0048] In some embodiments, a positioning notch 371 is formed on the front end face of the first rear wall portion 37, and a positioning protrusion 571 is provided on the rear end face of the second rear wall portion 57. When the first plastic body 30 is assembled onto the second plastic body 50, the positioning protrusion 571 is positioned at the positioning notch 371.
[0049] In some embodiments, a snap-fit structure is formed between the first plastic body 30 and the second plastic body 50, and when the first plastic body 30 and the second plastic body 50 are assembled together, the snap-fit structure snaps together.
[0050] Specifically, the rear ends of the first plastic body 30 are respectively formed with through grooves 38 extending vertically, and the rear ends of the second plastic body 50 are respectively formed with buckles 58. Each buckle 58 includes a connecting arm 581 and a buckle portion 582 protruding to one side from the end (lower end) of the connecting arm 581. When the first plastic body 30 and the second plastic body 50 are assembled, the buckle 58 extends into the groove 38, and the buckle portion 582 is pushed to one side within the groove 38. After the buckle portion 582 extends out of the groove 38, the buckle 58 is released elastically, and the buckle portion 582 is held at the bottom of the side wall of the groove 38.
[0051] In some embodiments, the Type-C female connector further includes a metal housing 70 sleeved on the outside of the outer plastic.
[0052] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. They should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the scope of this application are still within the scope of this application.
