[0023] Reference Figures 1 to 5 As shown, the utility model provides an electronic relay, including: a 3D printing box 1, a circuit board 2 and a terminal 3.

[0024] The 3D printing box 1 is made of 3D printed plastic material and is in a rectangular shape.

[0025] Specifically, the 3D printing box 1 includes a base 11 and a cover plate 12 which are arranged opposite to each other.

[0026] In this embodiment, the base and the cover are rectangular in shape, and the size of the base is slightly smaller than that of the cover.

[0027] A plurality of platforms 115 are formed on the inner side of the base 11. The platforms are respectively arranged at the four corners of the base. A plug-in ring wing 111 is formed on the outer edge of the base 11. The plug-in ring wing is arranged in a circle along the circumferential direction of the base. The plug-in ring wing 111 is arranged toward the cover plate 12. The plug-in ring wing 111 is arranged perpendicular to the base. The plug-in ring wing 111 is arranged on the inner side of the base. A plurality of accommodating grooves a are formed on the outer side of the plug-in ring wing 111. A stop block 112 is formed in the accommodating groove.

[0028] The outer edge of the cover plate 12 forms a socket ring wing 121. The socket ring wing 121 is arranged toward the base 11. The socket ring wing is arranged in a circle along the circumferential direction of the cover plate. The socket ring wing 121 is arranged perpendicular to the cover plate. The socket ring wing 121 is detachably sleeved on the outside of the plug ring wing 111. A locking block 122 is formed on the inner side of the socket ring wing 121. The locking block 122 is pressed against the side of the stop block 112 that faces away from the cover plate 12.

[0029] As a preferred embodiment, the locking block 122 is wedge-shaped. The locking block has a first side close to the cover plate and a second side away from the cover plate. The second side of the locking block is inclined. The second side of the locking block is inclined upward toward the cover plate.

[0030] As a preferred embodiment, the stop block 112 is wedge-shaped. The stop block has a first side close to the base and a second side away from the base. The second side of the stop block is inclined. The second side of the stop block is inclined upward toward the base. The width of the stop block is adapted to the width of the locking block.

[0031] When assembling the cover and the base,

[0032] The root of the plug ring wing 111 close to the base plate is formed with a plurality of reinforcing corner plates 113. The socket ring wing 121 is formed with a plurality of notches c. The reinforcing corner plates 113 are embedded in the notches c.

[0033] The base 11 is rectangular in shape. The reinforcing corner plates 113 are arranged at the corners of the base 11 .

Specifically, the switch function is realized by the circuit pattern of the circuit board itself and the components installed on the circuit board.

[0039] In this embodiment, a shock-absorbing pad is provided on the support platform and is arranged between the circuit board and the support platform.

[0040] There are multiple terminals 3. The terminals are welded and mounted on the circuit board. The terminals are used to electrically connect the circuit board to the outside. The support platform 115 is provided with a through hole that penetrates the base 11. The terminal 3 is inserted into the through hole. One end of the terminal 3 is connected to the circuit board 2. The other end of the terminal 3 extends to the outside of the outside.

[0041] The electronic relay of the utility model installs the circuit board on the support platform of the base in the 3D printing box. The circuit board has a switch function, so no running noise is generated at all, thereby greatly reducing the noise of products using the electronic relay. The 3D printing box of the electronic relay of the utility model is easy and quick to assemble, and the operability of the assembly operation is better.

[0042] The base of the electronic relay of the utility model is formed with a reinforced corner plate, which improves the structural stability of the base and the stability of circuit board assembly.
