Then, please refer to the third figure and the sixth figure to the eleventh figure, wherein, the sixth figure shows the exploded view of the interface card fixing assembly and the interface card provided by the preferred embodiment of the present invention; the seventh figure shows the exploded view of the interface card A-A sectional view of Figure 6; Figure 8 is a schematic diagram showing that the interface card is assembled along the assembly direction and contacting the guide to reach the top; Figure 9 is a schematic diagram showing that the interface card continues to be assembled along the assembly direction and moves against the guide to the top; The tenth figure is a schematic diagram showing that the interface card continues to be assembled along the assembly direction and the guide is engaged with the top to the side hole; Stereo view of the fixed interface card. As shown in the figure, an interface card 2 is inserted into the interface card fixing assembly 1 along the assembly direction D1.

Two sides of the interface card 2 each have a protruding portion 21a, 21b. The protruding part 21b cannot be seen clearly from the perspective of the figure, so the protruding part 21a is used as an example for illustration. The protruding part 21a is provided with a through hole H6a, so as to form a first protruding section 211a and a second protruding section 212a, as shown in FIG. As shown in the sixth figure. During assembly, the interface card 2 is inserted into the guide slots Ta, Tb by using the protrusions 21a, 21b. Since the fixed operating member 13 is located on the guide rail 12a, the following description will focus on the components on the side of the guide rail 12a, as shown in FIG. 7 . In addition, the perspective of the seventh figure shows and marks the second positioning groove H4a of the guide rail 12a. You can refer to the second positioning groove H4a and the first positioning groove H3a of the guide rail 12a in the third figure to know the second positioning groove The adjacent corresponding relationship between H4a and the first positioning groove H3a.

When the interface card 2 is inserted into the interface card fixing assembly 1 along the assembly direction D1, the protruding portion 21a of the interface card 2 will move in the guide groove Ta. When the interface card 2 continues to move along the assembly direction D1 , the first protruding section 211 a of the protruding portion 21 a will contact the fixed operating member 13 . In more detail, the first protruding section 211a will contact the guiding slope A1 guiding the top 133 , as shown in FIG. 8 .

Because the inclination direction D2 of the guide slope A1 is inclined to the assembly direction D1, when the interface card 2 continues to move along the assembly direction D1, the first protruding section 211a will be guided against the top 133 along the guide slope A1, so that The fixed operating member 13 moves along a moving direction D5 to compress the elastic element 14, and is located above the first protruding section 211a, as shown in FIG. 9 . Therefore, although part of the guiding abutment top 133 is originally located in the guiding groove Ta, due to the relationship of the guiding slope A1, it will not block the insertion of the interface card 2 into the interface card fixing assembly 1 along the assembling direction D1. It should be noted that, in this embodiment, the moving direction D5 is parallel to the extending direction D3, so it will be marked as the moving direction D5 or the extending direction D3 according to the drawing requirements. In this embodiment, however, the contact surface A3 will abut against the guide rail 12a when the fixed operating member 13 moves along the moving direction D5, so as to prevent the fixed operating member 13 from continuing to move along the moving direction D5.

Next, the interface card 2 continues to move along the assembly direction D1. When the through hole H6a is aligned with the guide and touches the top 133, the elastic element 14 will use the elastic restoring force to make the fixed operating part 13 move back, so that part of the guide touches the top 133. To the through hole H6a, as shown in the tenth figure, and then achieve the effect of automatic locking and fixing. That is to say, as long as the interface card 2 is operatively inserted into the interface card fixing assembly 1 along the assembling direction D1, the interface card fixing assembly 1 can accommodate and automatically fix the interface card 2 .

Because the elastic element 14 utilizes the elastic restoring force to return the fixed operation member 13 , the abutting surface A2 of the guiding abutting top 133 will be used for abutting against the first protruding section 211 a or against the first protruding section 211 a. Therefore, the interface card 2 cannot be pulled out from the interface card fixing assembly 1 along the removal direction D4, so that the interface card fixing assembly 1 can accommodate and fix the interface card 2 to achieve the effect of fixing and anti-removal, as shown in the eleventh figure Show. Preferably, the extension direction D3 of the abutting surface A2 is substantially perpendicular to the removal direction D4.

The shell 11 covers the interface card 2 to achieve the effect of electromagnetic shielding. The heat dissipation holes H2 of the housing 11 can achieve the effect of heat dissipation.

Finally, please refer to the third figure and the twelfth figure to the fourteenth figure together, wherein, the twelfth figure is a perspective view showing that the fixed operating member provided by the preferred embodiment of the present invention is operated and moved; the thirteenth figure Figure 12 is a sectional view of B─B in Figure 12; and Figure 14 is a schematic diagram showing the interface card being pulled out from the interface card fixing assembly along the removal direction.

As shown in FIG. 12 , when the interface card 2 is to be pulled out from the interface card fixing assembly 1 along the removal direction D4 , the fixing operating member 13 is operated to move along the moving direction D5 and compress the elastic member 14 .

The fixed operating part 13 can be regarded as a dip switch, and the user toggles the operating part 132, so that the operating part 132 drives the fixed operating part 13 to move along the moving direction D5, so that the guide top 133 is separated from the through hole H6a of the interface card 2 , as shown in Figure 13.

Then, the first protruding section 211a of the interface card 2 will not be abutted by the abutting surface A2 of the guiding abutment 133 or will not abut against the abutting surface A2 of the guiding abutting top 133, therefore, the interface card 2 can be operatively pulled out from the accommodating space S of the interface card fixing component 1 along the removal direction D4, as shown in the fourteenth figure.

Because there is no need to operate any components when the interface card 2 is inserted into the interface card fixing assembly 1 along the assembly direction D1, and when the interface card 2 is pulled out from the accommodating space S of the interface card fixing assembly 1, it only needs to be toggled in the switch hole H1 The operation part 132, therefore, no matter it is assembled or removed, it is not necessary to open the entire case cover as in the prior art.
