Figure 7This shows a cross-sectional view of a connector assembly according to a first embodiment of the present invention.

[0038] like Figures 1 to 7 As shown, in an exemplary embodiment of this utility model, an electrical connection module 1 is disclosed. The electrical connection module 1 includes terminals 2 and a housing 3. Terminal 2 includes a mating end 21, a connecting end 22, and a connecting portion 23. The mating end 21 is adapted to mate with the mating terminals 7 of a connector 5. The connecting end 22 is adapted to be electrically connected to a circuit board 4. The connecting portion 23 is connected between the mating end 21 and the connecting end 22. The connecting portion 23 of the terminal 2 is fixed to the housing 3, and the mating end 21 and the connecting end 22 of the terminal 2 are at least partially located outside the housing 3. The housing 3 is adapted to be fixedly connected to the circuit board 4 to position and support the terminal 2, thereby effectively ensuring the positional accuracy of the terminal 2.

[0039] like Figures 1 to 7 As shown in the illustrated embodiment, the electrical connection module 1 includes multiple terminals 2 arranged side by side, and the multiple terminals 2 are respectively fixedly connected to the housing 3.

[0040] Specifically, multiple terminals 2 are arranged side-by-side along the transverse Y direction of the electrical connection module 1, such that the mating ends 21 of the multiple terminals 2 are aligned in the longitudinal X and height Z directions of the electrical connection module 1. The longitudinal X direction is the direction in which the terminal 2 is inserted into the mating terminal 7, the height Z direction is parallel to the direction in which the terminal 2 is inserted into the circuit board 4, and the transverse Y direction is perpendicular to both the longitudinal X and height Z directions. Thus, the multiple terminals 2 and the housing 3 are assembled into a single component, allowing multiple terminals 2 to be simultaneously plugged into multiple mating terminals 7 in the connector 5, reducing the number of insertions required by the operator and saving manpower and time.

[0041] like Figures 1 to 7 As shown, in the illustrated embodiment, the housing 3 includes a slot 31, at least a portion of the connecting portion 23 is located in the slot 31 and is fixedly connected to the housing 3 via the slot 31.

[0042] like Figures 1 to 7 As shown, in the illustrated embodiment, the housing 3 includes a plurality of slots 31, and a plurality of terminals 2 are respectively inserted into the plurality of slots 31.

[0043] In the illustrated embodiment, the electrical connection module 1 includes two terminals 2, and the housing 3 includes two slots 31. In other embodiments not illustrated, the number of terminals 2 and slots 31 can be adjusted as needed.

[0044] like Figures 1 to 7 As shown in the illustrated embodiment, the slot 31 and the connecting part 23 are fixedly connected by an interference fit.

[0045] In other embodiments not shown, the slot 31 and the connecting part 23 are fixedly connected by snap-fit ​​or other means.

[0046] like Figures 1 to 7 As shown, in the illustrated embodiment, the housing 3 further includes a support surface 30, which is adapted to support the surface of the circuit board 4.

[0047] like Figures 1 to 7 As shown in the illustrated embodiment, the mating end 21 is generally flat, and its thickness direction is generally perpendicular to the support surface 30, meaning the mating end 21 is generally parallel to the circuit board 4. Compared to the typical arrangement of insert-type terminals that are generally perpendicular to the circuit board 4, the terminal 2 in the illustrated embodiment has a smaller dimension in the height direction Z, and the height of the assembly formed after the electrical connection module 1 and the connector 5 are mated is also smaller. This helps to reduce the overall height of the parts connected to the circuit board 4 and reduce the overall space occupied by the parts on the circuit board 4.

[0048] like Figures 1 to 7 As shown, in the illustrated embodiment, the housing 3 further includes a bottom surface 35 and a support portion 36, the support portion 36 extending from the bottom surface 35 in a direction away from the bottom surface 35 and including a distal end 361 away from the bottom surface 35, the distal end 361 providing a support surface 30.

[0049] like Figures 1 to 7 As shown in the illustrated embodiment, the housing 3 further includes a first end face 33 and a misalignment prevention part 34. The first end face 33 is located on the side of the housing 3 near the mating end 21, and the misalignment prevention part 34 extends from the first end face 33 in a direction away from the first end face 33 and parallel to the mating end 21 (i.e., longitudinal direction X). Correspondingly, a misalignment prevention groove 61 is provided on one side of the connector housing 6 of the connector 5 in the height direction Z. The misalignment prevention part 34 is adapted to be inserted into the misalignment prevention groove 61 to ensure that the electrical connection module 1 and the connector 5 are mated in the correct orientation.

[0050] like Figures 1 to 7 As shown, in the illustrated embodiment, the foolproof part 34 includes a pin 341 that extends beyond the support surface 30 and is adapted to be inserted into a corresponding positioning hole 42 of the circuit board 4.

[0051] like Figures 1 to 7 As shown, in the illustrated embodiment, the foolproof part 34 includes a first stepped surface 342, which provides a support surface 30.

[0052] like Figures 1 to 7 As shown, in the illustrated embodiment, the housing 3 further includes a mounting portion 32 that extends beyond the support surface 30 and is adapted to engage with a corresponding mounting hole 41 on the circuit board 4.

[0053] In the illustrated embodiment, the housing 3 includes two mounting portions 32, which are respectively disposed on opposite sides of the housing 3 in the transverse Y direction. In other embodiments not illustrated, the number of mounting portions 32 can be adjusted as needed.

[0054] like Figures 1 to 7 As shown in the illustrated embodiment, the mounting portion 32 includes a rod portion 321 and a stepped portion 322. The rod portion 321 includes a free end 321a away from the support surface 30. The stepped portion 322 is disposed near the free end 321a and includes a second stepped surface 322a, the orientation of which is opposite to that of the support surface 30. The mounting portion 32 is sized such that after the rod portion 321 passes through the mounting hole 41, the stepped portion 322 can stop on the lower surface of the circuit board 4 away from the mating end 21 to prevent the rod portion 321 from exiting the mounting hole 41.

[0055] like Figures 1 to 7 As shown in the illustrated embodiment, the step portion 322 further includes an outer end 322b away from the rod portion 321, and the mounting portion 32 further includes a ramp 323. The ramp 323 is inclined to the support surface 30 and extends from the free end 321a of the rod portion 321 toward the outer end 322b of the step portion 322.

[0056] The housing 3 is made of plastic, giving the rod 321 elasticity. When the free end 321a of the mounting portion 32 is inserted into the mounting hole 41, the inclined surface 323, under the pressure of the edge of the mounting hole 41, causes the rod 321 to be biased towards the rear side of the inclined surface 323, allowing the stepped portion 322 to pass smoothly through the mounting hole 41. After the stepped portion 322 has completely passed through the mounting hole 41, the inclined surface 323 is no longer compressed, and the rod 321 springs back, allowing the stepped portion 322 to stop against the lower surface of the circuit board 4.

[0057] like Figures 1 to 7 As shown, in another exemplary embodiment of this utility model, a connector assembly is also disclosed. The connector assembly includes a connector 5 and the aforementioned electrical connection module 1. The connector 5 includes a connector housing 6 and mating terminals 7 disposed within the connector housing 6. The mating end 21 of the terminal 2 of the electrical connection module 1 is inserted into the connector housing 6 and makes electrical contact with the mating terminal 7.

[0058] like Figures 1 to 7 As shown in the illustrated embodiment, the electrical connection module 1 includes a plurality of terminals 2 arranged side by side, and the connector 5 includes a plurality of mating terminals 7 arranged side by side, wherein the mating ends 21 of the plurality of terminals 2 are mated with the plurality of mating terminals 7 respectively.

[0059] like Figures 1 to 7 As shown, in the illustrated embodiment, connector 5 further includes cable 8, which is electrically connected to mating terminal 7 and leads out from connector housing 6.

[0060] Second Embodiment

[0061] Figure 8 This diagram shows a perspective view of the electrical connection module 1 according to a second embodiment of the present invention.

[0062] and Figures 1 to 7 Compared to the first embodiment shown, Figure 8 The main difference in the second embodiment shown is that the second end face 324 of one end of the mounting portion 32 of the housing 3 is flush with the support surface 30. This mounting portion 32 is adapted to be fixedly connected to the surface of the circuit board 4 by, for example, surface mount technology. Other technical features of the second embodiment are basically the same as those of the first embodiment, and can be referred to accordingly. Figures 1 to 7 The first embodiment shown.
