Problems solved by technology
[0004]1. Hanging a backpack on the side will increase the size of the circuit breaker and make the circuit breaker more bloated
[0005]2. Hanging the backpack on the side will affect the installation of other accessories on the circuit breaker
[0006]3. Hanging the backpack on the side will undoubtedly increase the production process and production cost of the circuit breaker
However, in the actual production process, the process requirements for inserting the opening parts are relatively high. The opening parts must be placed vertically into the installation hole. Unnecessary waste caused by component damage, which undoubtedly increases the production cost of circuit breakers to a certain extent

Embodiment
[0023] Example: Combined figure 1 , figure 2 As shown, the circuit breaker base 1 provided in this embodiment has a mounting slot 2 for accommodating the power board in the middle of the front, and a number of screw mounting holes 3 are provided around the back of the circuit breaker base 1, each The diameters of the screw mounting holes 3 are 3 mm, which are all smaller than the diameter of the mounting screws 3.5 mm.
[0024] The front of the circuit breaker base 1 provided in this embodiment has a mounting groove 2, and the power board is placed in the mounting groove 2, and the power line can be routed from the wiring groove originally provided on the circuit breaker base 1. The inner extension is connected to the static contact and the front-end power supply. It is not necessary to assemble the power board in the form of a side-mounted backpack as in the prior art, which saves space, makes the overall structure of the circuit breaker simple, and also saves install...

The invention discloses a breaker pedestal which is characterized in that a mounting groove for accommodating a power supply board is formed on the breaker pedestal. In the breaker pedestal, the mounting groove for accommodating the power supply board is arranged, thus the power supply board is not required to be assembled in a backpack lateral hanging mode in the prior art, so that the space is saved, the breaker has a concise whole structure, the mounting cost is saved, and simultaneously mounting of other accessories of other breakers is facilitated. An opening part is not required to be embedded when a bolt is knocked into a bolt mounting hole, so that the production process is greatly simplified, the opening part is effectively protected from damage, and the production cost is further saved.
Description
technical field [0001] The invention relates to a circuit breaker base. Background technique [0002] The base is a relatively important part of the circuit breaker, which is usually used to fix the trigger mechanism, thermal elements, electronic components and static contacts. If a tree is used to describe the circuit breaker, then the base is equivalent to a large tree. The root of the tree shows the importance of the base. [0003] Existing circuit breakers, especially plastic case small intelligent circuit breakers (common types 160 and 250) as an example, due to the limitation of the size of the circuit breaker body, the electronic components are composed of two parts, one is the controller Part, the second is the power board part. The existing above-mentioned circuit breakers all have a built-in controller, and an external power board, which exists in the form of a backpack hanging on the side. The disadvantages brought about by this are as follows: [0004] 1. Hang...
