Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a manufacturing method of a connector and the connector. Background Art

[0002] Connectors are used to connect various electronic devices electrically. To facilitate connection, existing technologies typically use a USB Type-C female connector structure. This female connector is compatible with both forward and reverse insertion, making it more convenient to use.

[0003] From the above, in order to meet the actual use requirements, this type of connector needs to be compatible with both forward and reverse plugging modes while having a small overall size. To this end, in the prior art, the connector includes two rows of terminals, one row of terminals consisting of a plurality of first terminals spaced apart along a first direction, and the other row of terminals consisting of a plurality of second terminals spaced apart along the first direction, the first terminals including a first contact portion, a first transition portion, and a first wiring portion arranged in sequence, the second terminals including a second contact portion, a second transition portion, and a second wiring portion arranged in sequence, the plurality of first contact portions and the plurality of second contact portions facing each other in a second direction, the second direction being perpendicular to the first direction, the connector realizes electrical connection with the male plug through the first contact portions and the second contact portions, the plurality of first contact portions cooperate with the plurality of second contact portions, thereby being compatible with both forward and reverse plugging modes. In addition, the first transition portion is connected between the first contact portion and the first wiring portion, and the second transition portion is connected between the second contact portion and the second wiring portion. Under the adjustment of the first transition portion and the second transition portion, several first wiring portions and several second wiring portions are arranged in sequence along the first direction, that is, in the second direction, the first wiring portion and the second wiring portion are arranged at the same height, thereby reducing the space occupied by the two rows of terminals.

[0004] In addition to the two rows of terminals, the connector also includes an injection molding structure that wraps around the periphery of the two rows of terminals, thereby fixing the relative positions of the terminals in any row of terminals and the relative positions of the two rows of terminals. Specifically, the injection molding structure includes five injection molding parts, and the five injection molding parts are injection-molded in two operations. In the first injection molding operation, one injection molding part is injection-molded around the periphery of each of the first contact portions and the first wiring portions, thereby preliminarily fixing the relative positions of the first terminals. In addition, one injection molding part is injection-molded around the periphery of each of the second contact portions and the second wiring portions, thereby preliminarily fixing the relative positions of the second terminals. After the first injection molding operation is completed, a second injection molding operation is performed. Specifically, in the second injection molding operation, the two rows of terminals with four injection molding parts are first assembled together, and then another injection molding part is injection-molded around the periphery of the four injection molding parts, the first transition portions, and the second transition portions to fix the two rows of terminals together.

[0005] During the first injection molding operation, since a fixed structure is not injection molded around the periphery of the first transition portion and the second transition portion, the first transition portion and / or the second transition portion are easily deformed during the second injection molding operation, thereby affecting the connector's ability to accurately transmit electrical signals between the two electronic devices.

[0048] This embodiment provides a method for manufacturing a connector, which is used to package two rows of terminals to obtain a connector, wherein: Figure 1 As shown, this embodiment takes two rows of terminals, namely the first terminal group 1 and the second terminal group 2, as an example. The first terminal group 1 includes a plurality of first terminals 11, and the first terminal 11 includes a first contact portion 111, a first transition portion 112 and a first wiring portion 113 arranged in sequence. The second terminal group 2 includes a plurality of second terminals 21, and the second terminal 21 includes a second contact portion 211, a second transition portion 212 and a second wiring portion 213 arranged in sequence.

[0049] Combine Figures 2 to 12 In this embodiment, the manufacturing method of the connector includes:

[0050] A first injection molded part 3 is injection molded around the periphery of the first terminal group 1 , the first injection molded part 3 covers all the first contact portions 111 and all the first wiring portions 113 , and all the first contact portions 111 and all the first wiring portions 113 are exposed from the first injection molded part 3 ;

[0051] A second injection molded part 4 is injection molded around the outer periphery of the second terminal group 2 , the second injection molded part 4 covers all the second contact portions 211 and all the second wiring portions 213 , and all the second contact portions 211 and all the second wiring portions 213 are exposed from the second injection molded part 4 ;

[0052] The first injection molded part 3 and the second injection molded part 4 are buckled together so that the plurality of first terminals 11 and the plurality of second terminals 21 are arranged at intervals along the first direction, and the plurality of first contact portions 111 and the plurality of second contact portions 211 are opposite each other along the second direction, the second direction is perpendicular to the first direction, the plurality of first wiring portions 113 and the plurality of second wiring portions 213 are arranged in sequence along the first direction, and the first injection molded part 3 and the second injection molded part 4 jointly wrap all the first transition portions 112 and all the second transition portions 212.

[0053] Based on the above, in this embodiment, the first injection molded part 3 is injection molded around the periphery of the first terminal group 1, and the second injection molded part 4 is injection molded around the periphery of the second terminal group 2, so that the first terminals 11 and the second terminals 21 are arranged at intervals along the first direction.

[0054] Moreover, all the first contact portions 111 are embedded in the first injection molded part 3 and are exposed from the first injection molded part 3, and all the first wiring portions 113 are embedded in the first injection molded part 3 and are exposed from the first injection molded part 3. That is, the first injection molded part 3 can wrap all the first contact portions 111 and all the first wiring portions 113 without affecting the electrical connection between the first contact portions 111 and the male plug, and without affecting the connection between the first wiring portions 113 and the electronic device.

[0055] Correspondingly, all second contact portions 211 are embedded in the second injection molded part 4 and are exposed from the second injection molded part 4, and all second wiring portions 213 are embedded in the second injection molded part 4 and are exposed from the second injection molded part 4, that is, the second injection molded part 4 can wrap all second contact portions 211 and all second wiring portions 213 without affecting the electrical connection between the second contact portions 211 and the male plug, and without affecting the connection between the second wiring portions 213 and the electronic device.

[0056] After the injection molding of the first injection molded part 3 and the second injection molded part 4 is completed, the first injection molded part 3 and the second injection molded part 4 are buckled together. After buckling, the plurality of first contact portions 111 and the plurality of second contact portions 211 are aligned one by one along the second direction, and the second direction is perpendicular to the first direction. It can be understood that the connector realizes electrical connection with the male plug through the first contact portion 111 and the second contact portion 211, and the plurality of first contact portions 111 cooperate with the plurality of second contact portions 211, thereby being compatible with both positive and reverse plugging modes.

[0057] Moreover, the first transition portion 112 is connected between the first contact portion 111 and the first wiring portion 113, and the second transition portion 212 is connected between the second contact portion 211 and the second wiring portion 213. The first transition portion 112 and the second transition portion 212 adopt a bending design. Under the adjustment of the first transition portion 112 and the second transition portion 212, several first wiring portions 113 and several second wiring portions 213 are arranged in sequence along the first direction.

[0058] Taking the first direction as the horizontal direction and the second direction as the vertical direction as an example, after the first injection molded part 3 and the second injection molded part 4 are fastened together, the plurality of first contact portions 111 and the plurality of second contact portions 211 are vertically aligned, i.e., the plurality of first contact portions 111 and the plurality of second contact portions 211 correspond one-to-one, and the corresponding first contact portions 111 and second contact portions 211 are arranged vertically aligned, thereby enabling compatibility with both forward and reverse plugging methods. The plurality of first wiring portions 113 and the plurality of second wiring portions 213 are arranged in sequence horizontally, i.e., the first wiring portions 113 and the second wiring portions 213 are arranged at the same height, thereby reducing the space occupied by the first terminal group 1 and the second terminal group 2.

[0059] Moreover, after the first injection molded part 3 and the second injection molded part 4 are fastened together, the first injection molded part 3 and the second injection molded part 4 jointly wrap all the first transition parts 112 and all the second transition parts 212 .

[0060] Based on the above, this embodiment injects a first injection molded part 3 on the periphery of the first terminal group 1 and injects a second injection molded part 4 on the periphery of the second terminal group 2. The first injection molded part 3 can wrap the first contact portions 111 and the first wiring portions 113 of all the first terminals 11, thereby fixing the relative positions of all the first contact portions 111 and all the first wiring portions 113. The second injection molded part 4 can wrap the second contact portions 211 and the second wiring portions 213 of all the second terminals 21, thereby fixing the relative positions of all the second contact portions 211 and all the second wiring portions 213. Moreover, the first injection molded part 3 and the second injection molded part 4 can cooperate to wrap all the first transition portions 112 and all the second transition portions 212, thereby fixing the relative positions of all the first transition portions 112 and all the second transition portions 212. Therefore, when other injection-molded structures are subsequently injection-molded around the first injection-molded part 3 and the second injection-molded part 4 to fix the first terminal group 1 and the second terminal group 2 together, the first transition portion 112 and / or the second transition portion 212 will not be deformed, thereby ensuring that the manufactured connector can accurately transmit electrical signals between the two electronic devices.

[0061] It can be understood that, similar to the prior art, when the first injection molded part 3 and the second injection molded part 4 are fastened together, a shielding spacer 8 needs to be stacked between the first injection molded part 3 and the second injection molded part 4. The shielding spacer 8 is stacked between the plurality of first contact portions 111 and the plurality of second contact portions 211. The shielding spacer 8 serves to isolate the signal, thereby preventing the first terminal group 1 and the second terminal group 2 from interfering with each other in signal transmission, thereby further ensuring that the connector can accurately transmit electrical signals between the two electronic devices.

[0062] Based on the above, the manufacturing method of the connector further includes:

[0063] After the first injection molded part 3 and the second injection molded part 4 are fastened together, a third injection molded part 5 is injection-molded around the first injection molded part 3 and the second injection molded part 4 , and all the first contact portions 111 , all the first wiring portions 113 , all the second contact portions 211 and all the second wiring portions 213 are exposed from the third injection molded part 5 .

[0064] As described above, the third injection molded part 5 is used to fix the first terminal group 1 and the second terminal group 2 together. Moreover, since all the first contact portions 111, all the first wiring portions 113, all the second contact portions 211 and all the second wiring portions 213 are exposed from the third injection molded part 5, the third injection molded part 5 does not affect the electrical connection between the first contact portions 111 and the second contact portions 211 and the male plug, and does not affect the connection between the first wiring portions 113 and the second wiring portions 213 and the electronic device.

[0065] Furthermore, the manufacturing method of the connector further includes:

[0066] After the third molded part 5 is injection molded, the housing 6 is assembled around the periphery of the third molded part 5 , and all first contact portions 111 , all first wiring portions 113 , all second contact portions 211 and all second wiring portions 213 are exposed from the housing 6 .

[0067] As described above, after the third injection molded part 5 is injection molded, the connector is manufactured by assembling the housing 6 on the periphery of the third injection molded part 5. Moreover, the housing 6 does not affect the electrical connection between the first contact portion 111 and the second contact portion 211 and the male plug, nor does it affect the connection between the first wiring portion 113 and the second wiring portion 213 and the electronic device.

[0068] See also Figures 1 to 12 The connector manufactured by the connector manufacturing method described above includes a first terminal group 1 and a second terminal group 2, the first terminal group 1 includes a plurality of first terminals 11, the first terminals 11 include a first contact portion 111, a first transition portion 112 and a first wiring portion 113 arranged in sequence, and the second terminal group 2 includes a plurality of second terminals 21, the second terminals 21 include a second contact portion 211, a second transition portion 212 and a second wiring portion 213 arranged in sequence.

[0069] Moreover, a plurality of first terminals 11 and a plurality of second terminals 21 are arranged at intervals along the first direction, wherein a plurality of first contact portions 111 and a plurality of second contact portions 211 are opposite to each other one by one along the second direction, and the second direction is perpendicular to the first direction. The connector realizes electrical connection with the male plug through the first contact portion 111 and the second contact portion 211, and the plurality of first contact portions 111 cooperate with the plurality of second contact portions 211, thereby being compatible with both positive and reverse plugging methods.

[0070] In addition, the first transition portion 112 is connected between the first contact portion 111 and the first wiring portion 113, and the second transition portion 212 is connected between the second contact portion 211 and the second wiring portion 213. Under the adjustment of the first transition portion 112 and the second transition portion 212, a plurality of first wiring portions 113 and a plurality of second wiring portions 213 are arranged in sequence along the first direction.

[0071] Taking the first direction as the horizontal direction and the second direction as the vertical direction as an example, the plurality of first contact portions 111 and the plurality of second contact portions 211 are arranged one-to-one in the vertical direction, that is, the plurality of first contact portions 111 and the plurality of second contact portions 211 correspond one-to-one, and the corresponding first contact portions 111 and second contact portions 211 are arranged in the vertical direction, thereby being compatible with both forward and reverse plugging methods. The plurality of first wiring portions 113 and the plurality of second wiring portions 213 are arranged in sequence in the horizontal direction, that is, the first wiring portions 113 and the second wiring portions 213 are arranged at the same height, thereby reducing the space occupied by the first terminal group 1 and the second terminal group 2.

[0072] In addition to the first terminal group 1 and the second terminal group 2 , the connector further includes a first injection molded part 3 and a second injection molded part 4 , wherein the first injection molded part 3 is molded around the periphery of the first terminal group 1 , and the second injection molded part 4 is molded around the periphery of the second terminal group 2 .

[0073] Specifically, all first contact portions 111 are embedded in the first injection molded part 3 and are exposed from the first injection molded part 3, and all first wiring portions 113 are embedded in the first injection molded part 3 and are exposed from the first injection molded part 3. That is, the first injection molded part 3 can wrap all first contact portions 111 and all first wiring portions 113 without affecting the electrical connection between the first contact portions 111 and the male plug, and without affecting the connection between the first wiring portions 113 and the electronic device.

[0074] Correspondingly, all second contact portions 211 are embedded in the second injection molded part 4 and are exposed from the second injection molded part 4, and all second wiring portions 213 are embedded in the second injection molded part 4 and are exposed from the second injection molded part 4, that is, the second injection molded part 4 can wrap all second contact portions 211 and all second wiring portions 213 without affecting the electrical connection between the second contact portions 211 and the male plug, and without affecting the connection between the second wiring portions 213 and the electronic device.

[0075] In addition, in this embodiment, the first injection molded part 3 and the second injection molded part 4 are buckled together and together wrap all the first transition parts 112 and all the second transition parts 212 .

[0076] Based on the above, in this embodiment, the first terminal group 1 is injection-molded with a first injection molded part 3 on the periphery, and the first injection molded part 3 can wrap the first contact portions 111 and the first wiring portions 113 of all the first terminals 11, thereby fixing the relative positions of all the first contact portions 111 and all the first wiring portions 113. The second terminal group 2 is injection-molded with a second injection molded part 4 on the periphery, and the second injection molded part 4 can wrap the second contact portions 211 and the second wiring portions 213 of all the second terminals 21, thereby fixing the relative positions of all the second contact portions 211 and all the second wiring portions 213. Moreover, the first injection molded part 3 and the second injection molded part 4 can cooperate to wrap all the first transition portions 112 and all the second transition portions 212, thereby fixing the relative positions of all the first transition portions 112 and all the second transition portions 212. Therefore, during the manufacturing process of the connector, when other injection-molded structures are injection-molded around the first injection-molded part 3 and the second injection-molded part 4 to fix the first terminal group 1 and the second terminal group 2 together, the first transition portion 112 and / or the second transition portion 212 will not be deformed, thereby ensuring that the manufactured connector can accurately transmit electrical signals between two electronic devices.
