Please refer to fig. 4, which is a top view of the area a in fig. 3; as shown in the figure, a fixing portion 1011 is disposed on the top wall 101 of the housing 10, the fixing portion 1011 has a through hole 1011a and an engaging hole 1011b, the through hole 1011a and the engaging hole 1011b are disposed along a first direction X, the through hole 1011a of the present embodiment is close to the first side wall 102 on the right side in fig. 1, the engaging hole 1011b is close to the first side wall 102 on the left side in fig. 1, the maximum inner diameter of the through hole 1011a is larger than the maximum inner diameter of the engaging hole 1011b, and a line connecting the center of the through hole 1011a and the center of the engaging hole 1011b of the present embodiment is parallel to the. The through hole 1011a and the engaging hole 1011b are communicated, the through hole 1011a and the engaging hole 1011b of the present embodiment are partially overlapped, the engaging hole 1011b has an engaging notch 1011c, the engaging hole 1011b is communicated with the through hole 1011a through the engaging notch 1011c, and the width of the engaging notch 1011c is smaller than or equal to the minimum inner diameter of the engaging hole 1011 b. The shape of the through hole 1011a and the shape of the engaging hole 1011b in this embodiment are both circular, and the shape of the through hole 1011a and the shape of the engaging hole 1011b may be triangular, elliptical, polygonal, or irregular, respectively.

Please refer to FIG. 5, which is a cross-sectional view taken along line A-A' of FIG. 1; as shown in the figure, the light guide member 11 has a light guide body 111 and a fastening protrusion 112, and one end of the fastening protrusion 112 is disposed on the light guide body 111 and protrudes from the light guide body 111. When the light guide 11 is assembled to the housing 10, the engaging protrusion 112 of the light guide 11 is located in the through hole 1011a on the right side in fig. 5. Then, the light guide 11 is moved from the right side in fig. 5 to the left side in fig. 5 (moved along the first direction X), so that the engaging protrusion 112 enters the engaging hole 1011b, and the light guide 11 is fixed on the top wall 101 of the housing 10, thereby preventing the width of the electrical connector 1 from increasing in the first direction X. Meanwhile, the through hole 1011a and the engaging hole 1011b of the fixing portion 1011 of the embodiment are disposed along the left and right sides of the first direction X, when the light guide 11 is pushed by an external force in the second direction Y, the light guide 11 will not move back from the engaging hole 1011b to the through hole 1011a, thereby effectively preventing the light guide 11 from being separated from the housing 10 when being pushed by the external force in the second direction Y.

In addition, the minimum outer diameter of the engaging protrusion 112 is slightly larger than or equal to the width of the engaging notch 1011c, so that the engaging protrusion 112 will not easily return to the through hole 1011a after entering the engaging hole 1011b, thereby effectively preventing the light guide 11 from escaping from the housing 10. The maximum outer diameter of the engaging protrusion 112 is slightly smaller than or equal to the minimum inner diameter of the engaging hole 1011b, so that the engaging protrusion 112 is effectively prevented from being displaced in the engaging hole 1011b, and the light guide 11 is prevented from moving relative to the housing 10.
