Description
[Technical field]
[0001] The present invention relates to the field of electrical connectors, and in particular to a method for manufacturing a terminal module and a connector assembly having the terminal module. [Background technology]
[0002] In the field of connectors, in order to improve the electrical characteristics of the signal terminal, an electrical connector with electronic components arranged on the signal terminal has emerged, wherein the production process of the terminal module of the connector includes: 1. First, the signal terminal and the ground terminal are formed by a stamping process. 2. The signal terminal and the ground terminal are arranged as inserts in the cavity of the injection mold by using an injection mold insert molding process, and the plastic fixing is molded by injection molding. Through this process, the signal terminal and the ground terminal are formed into one piece with the plastic fixing. 3. A plurality of through holes corresponding to the plurality of signal terminals are reserved on the plastic fixing. The shear cutter cuts off a small section of the signal terminal in the middle of the plastic fixing through the through hole to form a fracture, so that the signal terminal becomes two separated parts. 4. Solder is set in the through hole corresponding to the position on the fracture that needs to be welded. 5. The first electronic component is welded on the fracture, and the two disconnected parts of the signal terminal are connected through the first electronic component. 6. Fill the inner through hole with glue by plastic injection or glue application. After the glue is cured, a plastic layer covering the first electronic component is formed, thereby obtaining a terminal module.
[0003] The terminal module made in this way is relatively complicated to manufacture. After the terminal module is formed, a shear knife is needed to cut the signal terminal to form a fracture. The shear knife needs to pass through the through hole of the plastic fixing to cut the signal terminal. If the terminal module is not positioned accurately, the shear knife may cut other parts of the terminal module, thereby damaging the entire terminal module, resulting in increased costs. In addition, as the terminal components are developed, they are getting smaller and smaller, resulting in small through holes that are not convenient for the shear knife to operate.
[0004] Therefore, it is necessary to provide a method for manufacturing a terminal module that is easy to manufacture and a connector assembly having the terminal module to overcome the above-mentioned defects. [Summary of the invention]

[0136] like Fig. 9 and Fig.10 , Fig.36 and Fig.37As shown, step eight: in the first embodiment and the third embodiment, the plurality of first core wires 71 in the first row of cables 7 are welded one by one to the tail portions 13 of the plurality of first differential terminals 1S, and the plurality of second core wires 72 are welded one by one to the second welding portions 23 of the plurality of ground terminals 2G, so as to obtain the terminal module 200.
[0137] The manufacturing method of the terminal module 200 in the second embodiment of the present invention is as follows:
[0138] like Fig. 22 As shown, step 1: the first metal sheet is formed into a plurality of pairs of the first differential terminals 1S and a first material strip 500 connecting the plurality of pairs of the first differential terminals 1S by a stamping process, and a plurality of positioning holes 601 are stamped on the first material strip 500, and the second metal sheet is formed into a plurality of the conductive terminals 2 and a second material strip 600 connecting the plurality of the conductive terminals 2 by a stamping process. The first material strip 500 is connected to the tails 13 of the plurality of pairs of the first differential terminals 1S, and the second material strip 600 is connected to the contact portions 22 of the plurality of the conductive terminals 2, wherein the plurality of the conductive terminals 2 have a plurality of pairs of the second differential terminals 2S and a plurality of the grounding terminals 2G arranged on opposite sides of each pair of the second differential terminals 2S.

[0140] like Fig.24 and Fig.25 As shown, step three: using the multiple positioning holes 601 on the second material strip 600 as anchor points, inserting multiple pairs of the first differential terminals 1S into the multiple grooves of the plastic seat 3, and making the multiple pairs of the first differential terminals 1S correspond one by one to the rear sides of the multiple pairs of the second differential terminals 2S, so that the multiple conductive terminals 2, the multiple pairs of the first differential terminals 1S and the plastic seat 3 are assembled into a whole, and forming a gap P between the first welding portion 12 of each first differential terminal 1S and the second welding portion 23 of a corresponding second differential terminal 2S, wherein each of the gaps P is located in a corresponding opening 401.

[0144] The beneficial effects of the present invention are as follows:
[0145] 1. The present invention forms the interval P by separately molding the first differential terminal 1S and the second differential terminal 2S from the beginning, and separating the first welding portion 12 of the first differential terminal 1S and the second welding portion 23 of the second differential terminal 2S. There is no need to cut the main body of the entire signal terminal by a shearing knife to form the interval P, which can facilitate the manufacture of the terminal module 200.
[0146] 2. Compared with fixing the second plastic part 3B by machine, using the plurality of positioning holes 601 on the second material strip 600 as positioning anchor points can facilitate more accurate installation of the first plastic part 3A to the second plastic part 3B, and also facilitate accurate installation of the electronic component 4.
[0147] 3. The positioning groove 31 is used to facilitate accurate positioning of the first welding portion 12 of the first differential terminal 1S and the corresponding second welding portion 23 of the second differential terminal 2S, which is beneficial to the welding of the electronic component 4 .
[0148] 4. Each of the partition blocks 32 is arranged between one of the first welding portions 12 and the second welding portion 23 of a corresponding second differential terminal 2S, so that the interval P formed by each of the first welding portions 12 and the second welding portion 23 of a corresponding second differential terminal 2S in the front-to-back direction X is within a specified range, so as to facilitate the alignment welding of the first docking portion 4a and the second docking portion 4b of the electronic component 4.
[0149] 5. The height of the upper surface of the partition block 32 is not higher than the first welding surface 121 of the corresponding first differential terminal 1S and the second welding surface 231 of the corresponding second differential terminal 2S, so as to avoid blocking the welding of the electronic component 4.
[0150] 6. In order to increase the welding area of the first welding portion 12 and the corresponding welding area of the second welding portion 23 of the second differential terminal 2S, so as to facilitate better welding of the electronic component 4, the third welding surface 122 is set on the left and right surfaces of the first welding portion 12, and the fourth welding surface 232 is set on the left and right surfaces of the second welding portion 23 of the second differential terminal 2S, and at the same time, the third welding surface 122 and the fourth welding surface 232 are exposed from a surface of the plastic seat 3 along the up and down direction Z, so that when spraying solder, in addition to the first welding surface 121 being connected to the first docking portion 4a by solder, the second welding surface 231 being connected to the second docking portion 4b by solder, the third welding surface 122 can also be connected to the first docking portion 4a by solder, and the fourth welding surface 232 can also be connected to the second docking portion 4b by solder.
[0151] 7. The plurality of openings 401 are arranged one-to-one corresponding to the plurality of intervals P, which is conducive to accurately welding the electronic component 4 on the corresponding first welding portion 12 and the second welding portion 23 of the second differential terminal 2S through the opening 401 .
[0152] 8. The electrostatic protection element 5 is provided to discharge the energy of static electricity to prevent electrostatic interference of the connector assembly.
[0153] 9. The first plastic part 3A is embedded in the second plastic part 3B, and the first plastic part 3A does not exceed the range of the second plastic part 3B in the front-to-back direction X. Such a configuration is conducive to the miniaturization of the terminal module 200.
[0154] 10. The plurality of protrusions 36 of the first plastic part 3A are correspondingly accommodated in the plurality of accommodating grooves 38 of the second plastic part 3B, wherein the first groove 381 blocks one side of the first welding portion 12 of the first differential terminal 1S in the vertical direction Z, so that the first welding portion 12 of the first differential terminal 1S and the corresponding second welding portion 23 of the second differential terminal 2S are flush in the vertical direction Z, which is conducive to the welding of the electronic component 4. The second groove 382 exposes the tail portion 13 of the first differential terminal 1S, which is convenient for the welding of the first core wire 71 in the first row of cables 7.
[0155] 11. The second welding portion 23 of the ground terminal 2G extends to the corresponding partition wall 39 and is arranged side by side with the tail portion 13 of the first differential terminal 1S along the left-right direction Y, which is beneficial for the first core wire 71 and the second core wire 72 in the first row of cables 7 to synchronously weld the first differential terminal 1S and the ground terminal 2G.
[0156] 12. The plurality of positioning grooves 35 on the first plastic part 3A and the plurality of positioning posts 41 on the second plastic part 3B are engaged with each other in the up-down direction Z. Such an assembly method is simple and reliable.
[0157] 13. Compared with setting the installation groove 33 in the directly exposed part of the first differential terminal 1S and the adjacent ground terminal 2G, setting the penetrating installation groove 33 on the plastic seat 3 can, on the one hand, limit and protect the electrostatic protection element 5 in the front-to-back direction X and the left-to-right direction Y, and on the other hand, facilitate the alignment and welding of the electrostatic element with the first differential terminal 1S and the adjacent ground terminal 2G.
[0158] 14. A portion of each placement groove 42 is molded on the first plastic part 3A, and another portion is molded on the second plastic part 3B. The placement groove 42 can be formed by docking the first plastic part 3A and the second plastic part 3B. At the same time, the first welding portion 12 and the corresponding second welding portion 23 of the second differential terminal 2S can be aligned and exposed in the placement groove 42. Compared with the first embodiment, this can avoid opening the opening 401 on the second plastic part 3B.
[0159] 15. The metal shielding sheet 6 covers the side of the first plastic parts 3A facing away from the terminal assembly 300 in the up-down direction Z, so as to cooperate with the second plastic part 3B to prevent the first plastic parts 3A from separating from the second plastic part 3B in the up-down direction Z.
