The main cable and several sensor cables pass through the connection port on the housing and are connected to the circuit board through sockets and slots, and the connection port is provided with a waterproof mechanism.

The waterproof mechanism includes an outer interface nut and an inner interface nut. The outer interface nut is connected to the outside of the wiring port of the housing through threads, and the end of the outer interface nut is connected to the outer wall of the housing. The inner interface nut It is screwed to the inner side of the wiring port of the housing, and the end of the inner interface nut is connected to the inner wall of the housing.

The slot is provided with a slot opening, a number of uniformly arranged pins, and the socket matched with the slot is provided with a plug-in, a number of evenly arranged wiring holes, the wiring hole is matched with the pins, and the slot mouth and the plug-in Cooperate.

The four corners of the housing are arc-shaped, the upper part of the housing is provided with a groove, the bottom of the upper cover is provided with a boss embedded in the housing, and the housing and the upper cover are provided with a number of screw holes corresponding to each other , There is a water-swelling rubber waterstop between the upper cover and the shell.

The beneficial effect of the waterproof junction box provided by the utility model is that the junction box has a simple structure and takes up less space, and multiple wiring ports can be designed and installed according to needs, and the wiring is convenient; all lines are connected in a waterproof junction box, which is convenient for maintenance , good waterproof effect.

Detailed ways

Referring to the accompanying drawings, the waterproof junction box provided by the utility model will be described in detail below in combination with the embodiments.

Example

Referring to Fig. 1-Fig. 7, the waterproof junction box of the present embodiment is connected with several sensor cables and total cables, and it includes a housing 4, an upper cover 5 matched with the housing 4, one side of the housing 4, The two ends are respectively provided with connection ports 1 connected with the sensor cable and the main cable, and the other side of the housing 4 is provided with a circuit board 6, and the circuit board 6 is provided with a plurality of slots 7, the main cable, the sensor line The ends of the cables are all provided with sockets 8 that match the slots 7, and the total cable and several sensor cables pass through the connection port 1 on the housing 4 and are connected to the circuit board 6 through the sockets 8 and the slots 7. The connection port 1 is provided with a waterproof mechanism.

The waterproof mechanism includes an external interface nut 2 and an internal interface nut 3. The external interface nut 2 is connected to the outside of the wiring port 1 of the housing 4 by threads, and the end of the external interface nut 2 is connected to the outside of the housing 4. Wall connection, the inner interface nut 3 is screwed to the inside of the wiring port 1 of the housing 4 , and the end of the inner interface nut 3 is connected to the inner wall of the housing 4 .

Described slot 7 is provided with slot opening 14, some evenly arranged pins 11, and socket 8 that cooperates with slot 7 is provided with inserter 15, some evenly arranged wiring holes 12, and described wiring hole 12 is connected with plug The pin 11 cooperates, and the socket opening 14 cooperates with the insert 15 .

The four corners of the housing 4 are arc-shaped, the upper part of the housing 4 is provided with a groove 9, and the bottom of the upper cover 5 is provided with a boss 13 embedded in the inside of the housing 4. A number of screw holes 10 corresponding to each other are provided, and there is a water-swelling rubber waterstop between the upper cover 5 and the housing 4 .
