The rivet post 23 is provided with a connecting plate 231 extending along the axial line 23a of the rivet post 23, and the clip 22 is provided at the end of the connecting plate 231.
The rivet 20 has two buckles 22, and the two buckles 22 are intersected; the connecting plate 231 is disposed between the two intersecting catches 22; the end of the connecting plate 231 is connected to a position where the two catches 22 intersect.
In order to enable the M.2 card 40 to be clamped after the rivet 20 is assembled on the rivet stem 10, the dimensions of the boss 21, the buckle 22 and other components of the rivet 20 are set as follows:
the diameter of the boss 21 is larger than the diameter of the through hole 11 of the rivet column 10 and smaller than the diameter of the rivet cap 24, the diameter of the rivet column 23 is smaller than the diameter of the through hole 11 of the rivet column 10, and the thickness of the connecting plate 231 is smaller than the diameter of the rivet column 23.
Specifically, the utility model provides an assembly process of M.2 card 40's fixing device as follows:
the riveting column 10 is fixed at one end of the main board, and the interface 31 is fixed at the other end of the main board opposite to the riveting column 10;
one end of the M.2 card 40 is clamped with the interface 31 of the mainboard 30;
the other end of the M.2 card 40 with the notch is placed on the end face of the top end of the riveting column in advance;
the buckle 22 of the rivet 20 penetrates through the notch of the M.2 card 40 and the through hole 11 of the rivet column 10, and the boss 21 of the rivet 20 is embedded into the notch of the M.2 card 40 and then abuts against the end surface of the top end of the rivet column 10;
an annular groove is formed between the rivet cap 24 of the rivet 20 and the rivet column 10, and the M.2 clamp 40 is clamped in the annular groove through a notch;
further, the rivet 20 is made of elastic plastic material, and in the process that the rivet 20 passes through the through hole 11 of the rivet column 10, the buckles 22 are elastically deformed, the two buckles 22 are folded toward the connecting plate 231 of the rivet column 23, and after the buckles 22 pass through the through hole 11 of the rivet column 10, the buckles 22 are restored to the original shape by the elasticity of the plastic material, so that the end of the m.2 card 40 provided with the notch is clamped between the rivet cap 24 and the rivet column 10.
The boss 21 of the rivet 20 provided by the embodiment can effectively prevent the m.2 card 40 from horizontally moving on the top end surface of the rivet column 10.
Preferably, the distance between the top surface of the buckle 22 and the end surface of the boss 21 is equal to the length of the through hole 11 of the rivet stud 10, and the length of the boss 21 is equal to the thickness of the m.2 card 40, so that after the rivet stud 20 and the rivet stud 10 clamp the m.2 card, the m.2 card 40 is prevented from shaking up and down due to external interference.
In some embodiments, as shown in fig. 2, the outer side surface 221 of the clip 22 is configured as a conical curved surface, so that when the clip 22 passes through the through hole 11, the clip 22 is in point contact with the through hole 11 to reduce the contact area and thus the friction force, and facilitate the clip 22 to pass through the through hole 11.
In order to prevent the snap 22 from being worn out when the rivet 20 is inserted through the through hole 11 of the rivet stud 10, the top surface 222 of the snap 22 and the inner surface 223 of the snap 22 facing the connecting plate 231 are formed as flat surfaces, and the thickness between the outer surface 221 and the inner surface 223 of the same snap 22 is gradually increased from both ends of the intersection line 2231 of the outer surface 221 and the inner surface 223 of the snap 22 in the direction along the midpoint of the intersection line 2231.
Further, the outer side 221 of the buckle 22 intersects with the top 222 of the buckle 22 to form an arc 2211; the distance between the arc 2211 and the axial line 23a of the rivet stud 23 is greater than the radius of the through hole 11 of the rivet stud 10, so that the top surface 222 of the buckle 22 can abut against the bottom end surface of the rivet stud 11 after the buckle 22 passes through the through hole 11 of the rivet stud 10.
With continued reference to fig. 2, the width of the connecting plate 231 and the width of the buckle 22 are configured to gradually decrease along the axial line 23a of the rivet stud 23 toward the intersection of the buckle 22 and the connecting plate 231, so as to form a form with a wider top and a narrower bottom, thereby improving the alignment between the rivet 20 and the rivet stud 10 during assembly.
