How To Reinforce The Push-type Terminal Block Connector Of The Drone Sd Card Holder If It Is Loose And Easy To Fall Off?

Looseness of the drone SD card holder push wire terminal block is a common problem, which may cause data loss or interruption of shooting. Here are several effective reinforcement methods:
1
1. Hot melt glue fixation method
After cleaning the area around the SD card holder, use a low-melting point hot melt glue gun to apply a small amount of glue around push in terminal block wire connector. Be careful to avoid metal contacts, and the amount of glue should be enough to fix without affecting plugging and unplugging. After solidification, test the smoothness of plugging and unplugging. If it is too tight, you can use a blade to trim the glue.

2. Epoxy resin reinforcement
For metal card holder push in wire terminal block, you can mix AB glue and apply it to the gap of the base. Use a toothpick to accurately dispense glue and let it stand for 24 hours to completely solidify. This method is suitable for long-term fixation, but be careful not to contaminate the spring contacts.

3. Structural reinforcement method
Cut a 0.1mm thick PET plastic sheet and cut it into an L-shaped bracket. Use double-sided tape to stick it between the bottom of the card holder and the circuit board to form a physical support. This method does not affect the appearance and is reversible.

4. Contact adjustment
If push fit terminal block connector is loose due to fatigue of spring sheet, you can use tweezers to gently bend the metal contact to increase its elasticity. Turn off the power before operation to avoid electrostatic damage.

5. Anti-drop buckle
The 3D printed micro buckle is installed on the edge of the card slot, or a modified SIM card holder spring sheet is used to increase the locking force.

Notes:
- Remove the battery before operation
- Avoid using corrosive glue such as 502
- Check the reinforcement effect regularly
- It is recommended to replace the entire card holder module for severe deformation

The emergency solution is to temporarily fix push connector block with insulating tape, but long-term use will affect heat dissipation. For high-frequency vibration scenarios, it is recommended to use silicone shock pads for buffering after reinforcement. If it is difficult to handle by yourself, you can contact the manufacturer to purchase a special reinforcement kit or return to the factory for repair.
