[0030] Please refer to Figures 1 to 9As shown, this utility model discloses an electrical connector that can be used as a surgical wiring harness. The electrical connector includes an electrical connection assembly 10 and an insulating shell 20, with the electrical connection assembly 10 at least partially disposed within the insulating shell 20. The insulating shell 20 is provided with a latching portion 201 for engaging with a mating connector, which helps improve the connection stability between the electrical connector and the mating connector.
[0031] In some embodiments, the insulating shell 20 is formed outside the electrical connection assembly 10 by injection molding, thereby achieving a stable connection between the electrical connection assembly 10 and the insulating shell 20.
[0032] Please refer to Figure 2 and Figure 5 As shown, the electrical connection assembly 10 includes a flexible circuit board 1 and a base 2. The flexible circuit board 1 is bendable, making it easy to wrap around both sides of the base 2 in the thickness direction. Using the flexible circuit board 1 instead of wires and terminals saves materials, reduces costs, and simplifies the structure.
[0033] Please refer to Figure 3 and Figure 6 As shown, the flexible circuit board 1 includes a body portion 11, a docking portion 12, and a tail portion 13, with the docking portion 12 connecting the body portion 11 and the tail portion 13. The docking portion 12 is arranged around both sides of the base 2 in the thickness direction, and the body portion 11 and the tail portion 13 are arranged on both sides of the base 2 in the thickness direction. At least one of the body portion 11 and the tail portion 13 is provided with a through hole, and the base 2 is provided with a positioning post passing through the through hole.
[0034] For details, please refer to Figure 3 and Figure 6 As shown, the base 2 includes a base 21 and a tongue 22 connected to the base 21. A mating portion 12 is arranged around both sides of the tongue 22 in the thickness direction. A body portion 11 and a tail portion 13 are located on both sides of the base 21 in the thickness direction. At least one of the body portion 11 and the tail portion 13 has a through hole, and the base 21 has a positioning post passing through the through hole. By providing the through hole and the positioning post to cooperate with each other, the flexible circuit board 1 and the base 2 can be positioned and installed, which is beneficial for the flexible circuit board 1 and the base 2 to be assembled into place.
[0035] In some embodiments, please refer to Figure 3 and Figure 6 As shown, the main body 11 has a first through hole 110, and the tail 13 has a second through hole 130. The base 21 has a first positioning post 211 and a second positioning post 212. The first positioning post 211 passes through the first through hole 110, and the second positioning post 212 passes through the second through hole 130. This arrangement facilitates quick positioning and installation of the flexible circuit board 1 and the base 2. During assembly, the first positioning post 211 is inserted into the first through hole 110, the flexible circuit board 1 is routed around the base 2, and then the second positioning post 212 is inserted into the second through hole 130.
[0036] In another embodiment, the main body 11 is provided with a first through hole 110, and the base 21 is provided with a first positioning post 211. The first positioning post 211 passes through the first through hole 110 to realize the quick positioning and installation of the flexible circuit board 1 and the base 2.
[0037] In another embodiment, the tail portion 13 is provided with a second through hole 130, and the base portion 21 is provided with a second positioning post 212, which passes through the second through hole 130. This arrangement facilitates quick positioning and installation of the flexible circuit board 1 and the base 2.
[0038] In some embodiments, please refer to Figure 3 and Figure 6 As shown, the first through hole 110 is a round hole, and the second through hole 130 is an oblong hole. By providing the oblong hole, the errors generated between the flexible circuit board 1 and the base 2 can be offset, achieving good assembly. In other embodiments, the first through hole 110 is an oblong hole, and the second through hole 130 is a round hole.
[0039] In this embodiment, the mating part 12 is bonded and fixed to the tongue part 22, and the body part 11 and the tail part 13 are both bonded and fixed to the base part 21. The side of the flexible circuit board 1 assembled with the base 2 is provided with an adhesive layer. During assembly, the release film outside the adhesive layer is peeled off, and then the flexible circuit board 1 is attached to both sides of the base 2.
[0040] Please refer to Figure 3 and Figure 6 As shown, the docking part 12 is provided with a first gold finger 121 and a second gold finger 122. The first gold finger 121 and the main body part 11 are located on the same side of the base 2, and the second gold finger 122 and the tail part 13 are located on the same side of the base 2. Both the first gold finger 121 and the second gold finger 122 are electrical contact points.
[0041] In some embodiments, please refer to Figure 8 As shown, both the first positioning post 211 and the second positioning post 212 are frustum-shaped.

The outer diameter of the second positioning post 212 also gradually decreases from the base 21 outwards, facilitating its insertion into the second through hole 130.
[0042] For details, please refer to Figure 9 As shown, the first positioning post 211 includes a first outer peripheral surface 2111 and a first end surface 2112. The first outer peripheral surface 2111 and the first end surface 2112 are transitioned by a first arc surface 2113, which facilitates the first positioning post 211 passing through the first through hole 110. The second positioning post 212 includes a second outer peripheral surface 2121 and a second end surface 2122. The second outer peripheral surface 2121 and the second end surface 2122 are transitioned by a second arc surface 2123, which facilitates the second positioning post 212 passing through the second through hole 130.
[0043] Please refer to Figure 3 As shown, the base 21 includes a first part 21a and a second part 21b. The first part 21a connects to the tongue 22 and the second part 21b. A first positioning post 211 and a second positioning post 212 are both located in the second part 21b. Specifically, the width of the second part 21b is greater than the width of the first part 21a, and a step 21c is formed at the connection between the second part 21b and the first part 21a. The insertion direction of the electrical connector is defined as forward. The step 21c is used to limit the movement of the electrical connection assembly 10 within the insulating shell 20, preventing it from moving forward. The end of the second part 21b also limits the movement of the electrical connection assembly 10 within the insulating shell 20, preventing it from moving backward.
