[0033] According to a general technical concept of the present invention, a terminal module is provided, comprising: a row of terminals and an insulating retainer. The row of terminals includes a plurality of first terminals and at least one second terminal. The insulating retainer is injection molded onto the row of terminals, thereby holding the row of terminals together. The second terminal includes: a main terminal and a bypass terminal.

Figure 12 This shows a cross-sectional view of the second terminal and the insulating retainer of a terminal module according to an exemplary embodiment of the present invention.

[0037] like Figures 5-12 As shown, in an exemplary embodiment of this utility model, a terminal module is disclosed. The terminal module includes a row of terminals 1 and an insulating retainer 5. The row of terminals 1 includes a plurality of first terminals 2 and at least one second terminal 3. The insulating retainer 5 is injection molded onto the row of terminals 1, thereby holding the row of terminals 1 together. The second terminal 3 includes a main terminal 31 and a bypass terminal 32. The main terminal 31 has a first body portion 311 extending between its two ends. The bypass terminal 32 is located on one side of the main terminal 31, and its two ends are respectively electrically connected to the two ends of the first body portion 311 of the main terminal 31. The bypass terminal 32 has a second body portion 321 extending between its two ends, with a predetermined gap between the first body portion 311 and the second body portion 321. Thus, the main terminal 31 and the bypass terminal 32 are connected in parallel to reduce the current flowing through the main terminal 31, thereby allowing the second terminal 3 to have a greater current capacity. Furthermore, since the main terminal 31 and the bypass terminal 32 are connected in parallel, when current flows through the main terminal 31 and the bypass terminal 32, the heat generated by the current can be dissipated through the main terminal 31 and the bypass terminal 32 respectively, which improves the heat dissipation efficiency and keeps the temperature of the second terminal 3 at a lower temperature.

[0038] In an exemplary embodiment of the present invention, the first terminal 2 includes a high-speed signal terminal, and the second terminal 3 includes a low-speed signal terminal or a power supply terminal.

[0039] like Figure 6 As shown, in an exemplary embodiment of this utility model, the first terminal 2 is a pair of high-speed signal terminals. That is, two high-speed signal terminals are arranged side by side close to each other to form a pair of high-speed signal terminals.

[0040] like Figure 6 As shown, in an exemplary embodiment of the present invention, the terminal module further includes: a plurality of grounding terminals 4. Each pair of first terminals 2 is arranged between two grounding terminals 4.

[0041] like Figure 6 As shown, in an exemplary embodiment of the present invention, the second terminal 3 is located in the middle of a row of terminals 1.

[0042] like Figure 6 As shown, in an exemplary embodiment of this utility model, a row of terminals 1 has eight pairs of high-speed signal terminals. A grounding terminal 4 is arranged between each pair of high-speed signal terminals.

[0043] like Figures 9-12 As shown, in an exemplary embodiment of this utility model, the insulating retainer 5 includes: a first insulating retainer 51 and a second insulating retainer 52. The first insulating retainer 51 is injection molded onto one end of a row of terminals 1. The second insulating retainer 52 is injection molded onto the other end of the row of terminals 1. One end of the first main body portion 311 of the main terminal 31 and one end of the bypass terminal 32 are held in the first insulating retainer 51, and the other end of the first main body portion 311 of the main terminal 31 and the other end of the bypass terminal 32 are held in the second insulating retainer 52.

[0044] Specifically, such as Figure 10 As shown, the first insulating retainer 51 extends generally along the width direction of a row of terminals 1. The first insulating retainer 51 has a plurality of first through holes 511, allowing the first terminal 2, grounding terminal 4, and main terminal 31 to pass through it. The first through holes 511 are arranged generally along the width direction of the row of terminals 1 and penetrate the first insulating retainer 51 generally perpendicular to the width direction. The first insulating retainer 51 also has a first bypass terminal positioning hole 512 for receiving one end of the bypass terminal 32. The first bypass terminal positioning hole 512 communicates with the first through hole 511 for receiving the main terminal 31, thereby holding one end of the first main body portion 311 of the main terminal 31 and one end of the bypass terminal 32 within the first insulating retainer 51.

[0045] Similarly, such as Figure 11As shown, the second insulating retainer 52 extends generally along the width direction of the row of terminals 1. The second insulating retainer 52 has multiple second through holes 521, allowing the first terminal 2, grounding terminal 4, and main terminal 31 to pass through it. The second through holes 521 are arranged generally along the width direction of the row of terminals 1 and penetrate the second insulating retainer 52 generally perpendicular to the width direction. The second insulating retainer 52 also has a second bypass terminal positioning hole 522 for receiving the other end of the bypass terminal 32. The second bypass terminal positioning hole 522 communicates with the second through hole 521 for receiving the main terminal 31, thereby holding the other end of the first main body portion 311 of the main terminal 31 and the other end of the bypass terminal 32 within the second insulating retainer 52.

[0046] like Figures 8-12 As shown, in an exemplary embodiment of this utility model, the second main body 321 of the bypass terminal 32 is provided with a receiving hole 322, and the second insulating retainer 52 is provided with a protrusion 523. The protrusion 523 extends into the receiving hole 322 to position the main terminal 31 and the bypass terminal 32 relative to each other. The receiving hole 322 gives the bypass terminal 32 good foolproof characteristics, thereby facilitating the operator to identify the two ends of the bypass terminal 32 connected to the main terminal 31.

Furthermore, in another exemplary embodiment of the present invention, the thickness of the second main body portion 321 is greater than the thickness of the first main body portion 311. Since the bypass terminal 32 exists independently of the main terminal 31, the thickness, width, or material of the bypass terminal 32 can be freely selected to meet the needs of different application scenarios.

[0048] like Figures 6-8 As shown, in an exemplary embodiment of the present invention, the main terminal 31 has an elastic contact portion 312 connected to one end of the first main body portion 311 for electrical contact with the mating power supply terminal, and an electrical connection portion 313 connected to the other end of the first main body portion 311 for electrical connection to the circuit board.

[0052] like Figures 6-8 and Figure 12 As shown, in an exemplary embodiment of the present invention, the elastic contact portion 312 of the main terminal 31 includes a pair of cantilever portions 314 arranged side by side, the pair of cantilever portions 314 being adapted to make simultaneous electrical contact with the mating power supply terminal.

[0056] like Figures 5-6 As shown, in an exemplary embodiment of this utility model, the grounding terminal 4 has an elastic contact portion for electrical contact with a mating grounding terminal. The terminal module further includes two grounding connectors 7. The two grounding connectors 7 are respectively disposed on the left and right sides of the main terminal 31. The grounding connector 7 on the left side is electrically connected to the elastic contact portions of a plurality of grounding terminals 4 located on the left side of the main terminal 31, and the grounding connector 7 on the right side is electrically connected to the elastic contact portions of a plurality of grounding terminals 4 located on the right side of the main terminal 31.

[0057] like Figure 5As shown, in an exemplary embodiment of the present invention, the terminal module further includes: an upper grounding shield 8 and a lower grounding shield 9.

[0059] like Figure 4 As shown, in an exemplary embodiment of this utility model, the inner housing 90 further comprises: a first side housing 92 and a second side housing 93. The first side housing 92 and the second side housing 93 are respectively connected to the left and right sides of the inner insulator 91 (i.e., on both sides of the width direction of the row of terminals 1). The first side housing 92 and the second side housing 93 are provided with positioning grooves 931. The positioning grooves 931 are recessed from the inner surfaces of the first side housing 92 and the second side housing 93 along the width direction of the row of terminals 1. The insulating retainer 5 of the terminal module is located in the positioning grooves 931, thereby positioning the inner housing 90 relative to the row of terminals 1.

[0060] like Figure 4 As shown, in an exemplary embodiment of this utility model, the inner shell 90 is an integral injection molded part.

[0061] like Figures 1-3 As shown, in an exemplary embodiment of the present invention, a connector is disclosed, comprising: a housing 10 and two connector modules as described above. The connector modules are mounted in the housing 10.

[0064] Specifically, such as Figures 1-2 As shown, the housing 10 has generally perpendicular width, depth, and height directions. The slot 101 extends along the width direction and is arranged vertically along the height direction. Each of the terminals 1 in the row of the upper connector module has a longer body portion, and each of the terminals 1 in the row of the lower connector module has a shorter body portion, so that the upper connector module generally covers the lower connector module. In the depth direction of the housing 10, the electrical connection portion 313 in the lower connector module is closer to the slot 101 than the electrical connection portion 313 in the upper connector module. Thus, the two connector modules are arranged vertically adjacent to each other.
