[0002] DeviceNet junction boxes are important network connectivity devices in industrial automation, primarily used to achieve distributed connections and expansion of DeviceNet bus networks. As a key component of DeviceNet fieldbus systems, junction boxes play a pivotal role in industrial control systems, effectively solving problems such as complex wiring and signal attenuation, thereby improving system reliability and flexibility.

[0003] Currently, the most common port counts for DeviceNet junction boxes on the market are 4, 8, and 16 ports. The 16-port terminals are relatively large, but there are few smaller 9-port products on the market, which cannot meet market demand. Utility Model Content

The circuit board is installed inside the junction box body. Nine terminals are installed on the top of the circuit board and are arranged in parallel on the top of the circuit board.

[0007] Furthermore, the junction box is made of aluminum profile and the end cap is made of stainless steel.

[0008] Furthermore, the end cap has two mounting holes on its surface, and clearance grooves are also provided on both sides of the end cap near the junction box.

[0009] Furthermore, it also includes hexagonal socket head cap screws, which limit the circuit board to the junction box.

[0010] Furthermore, the type of the hex socket head cap screw is M3*5, and the quantity of the hex socket head cap screw is 4.

[0011] Furthermore, the distance between the terminals is A, and the value of A is 12.4 mm.

[0012] Furthermore, the distance between the center lines of the two terminals is B, and the value of B is 13.8 mm.

[0013] Furthermore, the mounting hole is a through hole structure, and the length of the straight section in the middle of the mounting hole is C, where C is 3mm.

[0014] Furthermore, the distance between the two mounting holes is D, and the value of D is 14mm.

[0015] Furthermore, the width distance of the mounting hole is E, and the value of E is 5mm.

[0016] Furthermore, the distance between the center lines of the mounting holes of the two end caps is F, and the value of F is 165mm.

[0017] Furthermore, the total length distance between the junction box and the two end caps is G, and the value of G is 175mm.

[0018] Compared with existing technologies, the compact DeviceNet junction box described in this utility model has the following advantages:

[0019] The present invention discloses a compact DeviceNet splitter box, which can meet market demand and fill the market gap for 9-port DeviceNet splitter boxes. Moreover, the splitter box is compact in shape, small in size, easy to install, and highly practical. Attached Figure Description
