Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

In the present application, a single-stage circuit breaker is taken as an example for explanation, but the present invention is not limited to the single-stage circuit breaker, and is also applicable to a bipolar circuit breaker, a three-stage circuit breaker, and a four-stage circuit breaker.

As shown in fig. 1-6, the utility model discloses a communication module 2 of thing networking circuit breaker, its appearance size is the same basically with circuit breaker body 1 and can dismantle with circuit breaker body 1 and be connected or fixed connection.

The communication module 2 comprises a shell 21, a circuit board 22 fixed in the shell 21, an antenna connector 23 connected with the circuit board 22, an antenna 24 connected with the antenna connector 23, and two groups of pins 3. The circuit board 22 is provided with a mobile phone card slot 221, which utilizes a mobile phone communication network to communicate, and has a wide receiving range. In the present embodiment, the antenna connector 23 is an SMA connector, and the connection pins on the SMA connector clamp the circuit board 22, and the connection pins are soldered to corresponding contacts on the circuit board 22 to ensure the reliability of connection. The shell 21 is provided with a notch 211 for the antenna connector 23 to pass through, the antenna connector 23 partially extends out of the shell 21 so as to facilitate the connection of the antenna 24, and in addition, the antenna connector 23 partially can be clamped on the shell 21 so as to avoid damaging the circuit board 22 when the antenna 24 is screwed on. A sealing ring can be additionally arranged in the gap between the notch 211 and the antenna joint 23 for sealing, so that dust is prevented from entering. The shell 21 is provided with a mounting hole 212 at an inlet position facing the mobile phone card slot 221, which is convenient for the mobile phone card to be inserted into the mobile phone card slot 221, and the mounting hole 212 is detachably plugged by a cover plate 217 to play a dustproof role.

Be equipped with round sand grip 213 on the lateral wall outside of shell 21 is along being equipped with round and sand grip 213 complex recess 11, and when shell 21 and the laminating of circuit breaker body 1, sand grip 213 and the cooperation of recess 11 formed seal structure, played sealed effect, avoided the dust to enter into in the shell 21. Be equipped with six first rivet holes 214 on shell 21, be equipped with six second rivet holes 12 with first rivet hole 214 one-to-one on circuit breaker body 1, first rivet hole 214 and second rivet hole 12 are the through-hole, and shell 21 and circuit breaker body 1 laminating back are connected through first rivet hole 214 of rivet locking and second rivet hole 12.
