Fig. 1 and 2 show schematic structural diagrams of the connector fixing device of the present application. The method specifically comprises the following steps: the flight controller 1 that is the cuboid, flight controller 1 comprises outside casing 11 and inside controller, and 11 one side of casing of flight controller 1 is provided with and is the first connector 2 of the rectangular slightly less connector that locates flight controller 1 side, and the parallel second connector 3 that inserts a plurality of connectors that evenly is provided with three rows of every row three row needle 21, row needle 21 in parallel. Two connecting plates 4 are correspondingly and fixedly arranged at two ends of the first connector 2 side of the flight controller 1, a fixing plate 5 which is clamped and connected with the connecting plates 4 is arranged between the connecting plates 4, and the second connector 3 can be fixed on the pin header 21 by the fixing plate 5.

Fig. 3 is a schematic structural diagram of the second connector 3. The second connector 3 comprises a thin cuboid end shell 31, three pin header ports 32 which can be inserted into a row of three pins 21 in the first connector 2 are uniformly arranged at the head of the end shell 31, and the second connector 3 can be vertically inserted into the first connector 2 along the row of pins 21; three connecting lines 33 extend out of the tail part of the end head shell 31 and the position opposite to the needle discharge port 32.

Fig. 4 is a schematic structural view of the connection plate 4. The connecting plate 4 is rectangular, two circular mounting holes 41 are formed in the left end of the connecting plate 4, and the connecting plate 4 can penetrate through the mounting holes 41 through bolts to be fixed on the shell 11; a rectangular clamping opening 42 is vertically formed at the right end of the connecting plate 4; the connecting plate 4 is provided with a lightening opening 43 in the same shape as the connecting plate 4 at the middle position.

Fig. 5 is a schematic structural view of the fixing plate 5. The main body 51 of the fixing plate 5 is rectangular; a small section of rectangular convex clamping joint 52 with the same shape as the clamping opening 42 extends outwards from the middle area of the left end and the right end of the main body part 51; the middle of the fixing plate 5 is provided with a rectangular threading opening 53 opposite to the first connector 2, the center of the threading opening 53 coincides with the center of the fixing plate 5, the length of the threading opening 53 is greater than that of the first connector 2, the height of the threading opening 53 is smaller than that of the tail of the second connector 3, and the height of the threading opening 53 is enough for the connecting line 33 of the second connector 3 to penetrate out.

Fig. 6 is an exploded view of the second connector 3 fixing device. A plurality of second connectors 3 are inserted into the first connector 2 vertically side by side; the connecting plates 4 penetrate through the mounting holes 41 through bolts and are fixed on two sides of the flight controller 1, and the connecting plates 4 extend out of the front of the first connector 2; the connecting wire 33 passes through the threading opening 53 of the fixing plate 5, and the fixing plate 5 is clamped and connected into the clamping openings 42 on the left and right connecting plates 4 through the clamping joints 52 at the two ends.

As can be seen from fig. 1 and 2, the width of the main body 51 of the fixing plate 5 is equal to the distance between the left and right connecting plates 4; after the fixing plate 5 is clamped and connected with the connecting plate 4, a part of the clamping interface can extend out of the clamping interface 42; the threading opening 53 is opposite to the connecting line 33 at the tail part of the second connector 3 of the pin header, and the fixing plate 5 is abutted against the tail part of the second connector 3.

Further, after the fixing plate 5 is installed, since the fixing plate 5 is subjected to a force applied by the second connector 3 to be perpendicular to the panel of the fixing plate 5, if the fixing plate 5 has poor rigidity, the fixing plate 5 may be separated from the engaging opening 42 due to deformation, thereby affecting the fixing of the second connector 3. Therefore, it is preferable to use a material, such as a glass fiber plate, which is thick and insulating, light in weight, and has a certain rigidity, as the material for making the fixing plate 5.

Further, the connecting plate 4 receives a force along the connecting plate 4 given by the fixing plate 5 after the mounting is completed, and thus the fixing of the second connector 3 can be satisfied using a material having a lower rigidity. Meanwhile, after the connecting plate 4 can deform to both sides to some extent, the fixing plate 5 can be more conveniently installed. Therefore, it is preferable to use a thin, lightweight, and somewhat elastic material, such as a carbon fiber plate, as the material for making the connection plate 4.

When in use, the second connector 3 is inserted into the first connector 2 after passing through the threading opening 53; after the insertion connection is completed, the clamping joint 52 at one end of the fixing plate 5 extends into the corresponding clamping opening 42, and because the length of the main body part 51 of the fixing plate 5 is equal to the distance between the connecting plates 4 at the left and right ends, the clamping joint 52 at the two ends of the main body part 51 cannot be arranged between the two connecting plates 4 at the left and right ends; because the connecting plate 4 is made of a thin carbon fiber plate with certain elasticity, and the weight-reducing opening 43 with the same shape as the connecting plate 4 is arranged in the middle of the connecting plate 4, the flexibility of the connecting plate 4 is further increased, the connecting plate 4 is bent towards two sides, and the clamping connector 52 can enter the clamping opening 42. Thus, after the engagement, the fixing plate 5 abuts against the tail of the second connector 3, thereby ensuring that the second connector 3 cannot be separated from the first connector 2.
