Wherein, other parts in this application all take any form in the prior art, such as: power on components, signal components, processors, management interfaces, memory, etc. If the main board can adopt the existing structure, but according to the structure of the application, a chip and the like are not arranged on the main board, and the main board is realized in an external connection mode. And installing the chips supporting various protocols in the plugging rod for plugging. The main board is a main circuit board, the auxiliary board is an auxiliary circuit board, the main board mainly realizes other functions of the existing gateway device except the chip, and the auxiliary board is used for electrically connecting the chip with the main board, so that the situation that too many plug-in interfaces are arranged on the main board is avoided. Each pin piece on the plug-in piece is electrically connected with each pin of the chip respectively, so that the mutual pins can be prevented from being influenced. By adopting the structure, compared with the prior art, the chip is directly welded on the main board, so that the chip can be conveniently replaced, the communication of multiple protocols can be realized by inserting the inserting rods with different chips, and the chips supporting different communication protocols can be replaced; and can avoid setting up too much grafting mouth on the mainboard thereby lead to the area too big.

Further, the lower end of the plug rod is provided with a plug column, and the shell is provided with a jack matched with the plug column; and the groove cover is provided with a connecting column matched with the jack. By the arrangement, the connection between the inserting connection rod and the shell can be more stable.

Further, a clamping groove is formed in the inserting connection rod, a mounting groove is formed in the shell corresponding to the clamping groove, a clamping block matched with the clamping groove is connected to the mounting groove in a sliding mode, and an elastic piece is arranged between the clamping block and the inner wall of the mounting groove. The arrangement can prevent the plugging rod from falling off in plugging, thereby affecting the integral use.

Further, the insert rod is provided with a waterproof ring matched with the groove. By the arrangement, water inflow at the groove can be prevented.

Further, the downside of waterproof ring is provided with the sealing washer. This arrangement can further enhance the sealing effect.

The beneficial effects are that: by adopting the structure, compared with the prior art, the chip is directly welded on the main board, so that the chip can be conveniently replaced, the communication of multiple protocols can be realized by inserting the inserting rods with different chips, and the chips supporting different communication protocols can be replaced; and can avoid setting up too much grafting mouth on the mainboard thereby lead to the area too big.
