In order to ensure the normal operation of the power supply system, the reliability of the universal circuit breaker must be ensured first. Therefore, in order to detect the operating life of the universal circuit breaker and count the number of times it is opened and closed, an operation counter is installed on the universal circuit breaker.

[0003] The existing operation counter is usually installed on the operating mechanism bracket of the universal circuit breaker, and the counter lever is driven by the connecting rod inside the operating mechanism to count. The operating mechanism is composed of a complex connecting rod driving structure and needs to be customized for installation. In summary, the existing operation counter installed on the universal circuit breaker has a complex structure and is relatively cumbersome to install. The vibration force generated by the opening and closing of the universal circuit breaker is transmitted to the operation counter through the operating mechanism, which makes the operation counter subject to long-term vibration shock, which is easy to cause loose installation and even damage the lever, resulting in failure to count, and poor reliability. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a new energy universal circuit breaker with a counting function, including a base and an operating mechanism, an auxiliary contact device and a cover shell arranged on the base. The operating mechanism cooperates with the auxiliary contact device. When executing the opening and closing of the circuit breaker, the operating mechanism drives multiple groups of normally closed contacts and multiple groups of normally open contacts in the auxiliary contact device to switch the opening and closing positions. The cover shell is installed on the front side of the base and covers the operating mechanism and the auxiliary contact device. An electronic counter connected to the auxiliary contact device is arranged on the cover shell, and the electronic counter has a group of signal terminals connected to a group of normally open contacts or a group of normally closed contacts.

[0006] As a preferred solution, the electronic counter is detachably mounted on the cover and is arranged opposite to the auxiliary contact device in front and back.

The operating mechanism 2 cooperates with the auxiliary contact device 3. When executing the opening and closing of the circuit breaker, the operating mechanism 2 drives multiple groups of normally closed contacts and multiple groups of normally open contacts in the auxiliary contact device 3 to switch the opening and closing positions. The cover 4 is installed on the front side of the base 1 and covers the operating mechanism 2 and the auxiliary contact device 3. It is characterized in that: an electronic counter 5 connected to the auxiliary contact device is arranged on the cover 4, and the electronic counter 5 has a group of signal terminals 51 connected to a group of normally open contacts or a group of normally closed contacts.

[0035] The above implementation mode is the core technical solution of this embodiment. The electronic counter 5 is installed on the cover 4 and connected to a group of normally open contacts or a group of normally closed contacts of the auxiliary contact device 3 through a group of signal wiring terminals 51. This electronic counter 5 mainly counts the number of electrical signal pulses in the digital system. According to the universal circuit breaker, the normally open contacts and normally closed contacts of the auxiliary contact device 3 are driven by the operating mechanism 2 to switch the opening and closing positions when the universal circuit breaker is opened and closed. Therefore, the electronic counter 5 can count the number of opening and closing times of the universal circuit breaker by cooperating with the auxiliary contact device 3, that is, the universal circuit breaker is counted once when it is closed and opened once, thereby realizing the counting function of the opening and closing of the circuit breaker. The electronic counter 5 using this technical solution can be effectively avoided by being installed on the cover 4. The vibration impact generated by the opening and closing of the operating mechanism 2 can be effectively avoided, and it only needs to be connected to the auxiliary contact device. The installation and connection are very convenient and reliable. At the same time, it is also convenient for users to observe that the electronic counter can know the number of opening and closing times of the universal circuit breaker, and the operating life of the product can be better detected.

[0036] Combine the following Figure 3-6 The specific setting method of the electronic counter is described in detail:

Such an installation design facilitates connecting the wire from the signal terminal 51 to the normally open contact of the auxiliary contact device 3, and the wiring distance is short and the wiring is convenient, thereby facilitating the installation and wiring between the electronic counter 5 and the auxiliary contact device 3. After the installation is completed, the electronic counter 5 will expose the display screen 53 on the outer side of the housing, and the user can clearly know the number of opening and closing times of the circuit breaker by observing the counting times of the display screen 53.

[0038] It is further preferred that the electronic counter 5 is provided with a reset button 54, and the electronic counter 5 has a set of reset terminals 52 connected to the reset button 54. The reset button 54 is operated once to reset the count value obtained by the electronic counter 5, thereby realizing the reset function of the electronic counter 5. This electronic counter is applied to the universal circuit breaker to play the counting function, and can also provide users with the functions of recording, selecting to reset, and adding reminder values ​​according to categories.

[0039] In this embodiment, the electronic counter 5 and the housing 4 are kept in a fixed relative position by a fixing structure. Figure 3-5The fixing structure includes a mounting bracket 7 and a limiting panel 6 which are arranged opposite to each other. The limiting panel 6 is arranged at one end of the electronic counter 5 and cooperates to abut against the outer surface of the cover shell. The mounting bracket 7 is connected to the other end of the electronic counter 5 through a fastening component 8, and is provided with a supporting card plate 71 which extends and abuts against the inner side of the cover shell 4. When the mounting bracket 7 is fixed, the supporting card plate 71 cooperates with the limiting panel 6 to press against the cover shell 4. The advantage of such an installation design is that when the electronic counter 5 is installed in the installation window of the cover shell 4, the limit baffle will be driven to abut against the outer side of the cover shell, and then the installation bracket 7 will be fastened to the other end of the electronic counter 5 by the fastening component 8. Under the action of the fastening force applied by the fastening component 8, the installation bracket 7 drives the support card plate 71 to cooperate and abut against the inner side of the cover shell, and under the continuous pressure of the fastening component 8, the support card plate 71 cooperates with the limit panel 6 to press against the cover shell 4, thereby realizing the installation and fixation of the electronic counter on the cover shell. The installation structure of this electronic counter is simple, the fit and fixation are reliable, and it is also convenient to disassemble, thereby improving the installation efficiency and enhancing the product performance.

[0040] It is further preferred that the fastening component 8 includes a screw structure 81 fixedly arranged at the other end of the electronic counter 5, and a locking nut 82 connected to the screw structure 81 for fastening the mounting bracket 7, and the mounting bracket 7 is formed with a connecting hole sleeved on the screw structure 81, wherein the electronic counter 5 includes a base plate 55 arranged at the other end thereof, and two partitions 56 arranged on the base plate 55 and separating the signal terminal 51 from the reset terminal 52 from each other, and a limiting groove 57 formed between the two partitions 56, the screw structure 81 is vertically connected to the limiting groove 57, and the mounting bracket 7 is fixed in the limiting groove 57 by the fastening component 8, and the limiting groove 57 plays a limiting installation role for the mounting bracket 7 at the other end of the electronic counter 5, thereby avoiding position displacement of the mounting bracket 7 during the installation and fixing process, and ensuring the accuracy and stability of the installation position of the mounting bracket 7. This structural arrangement is such that during installation, the mounting bracket 7 is sleeved on the screw structure 81, and a tightening force is applied to the mounting bracket 7 by tightening the locking nut 82, so that the mounting bracket 7 is firmly fixed to the other end of the electronic counter 5 under the pressure of the locking nut 82, and at the same time drives the supporting card 71 to press against the inner side of the cover shell 4, and the supporting card and the limiting panel cooperate to press against the cover shell 4, thereby playing the role of installing and fixing the electronic counter 5 on the cover shell 4; and if the electronic counter 5 needs to be disassembled, just loosen the locking nut 82 and remove the mounting bracket 7 from the screw structure 81, so that the electronic counter can be removed from the installation window of the cover shell, and both installation and disassembly are relatively convenient.

[0041] like Figure 3 As shown, the mounting bracket 7 is in a U-shaped structure, which includes a flat plate portion connected to the limiting groove 57, and two supporting clamps 71 bent at both ends of the flat plate portion and extending on both sides of the electronic counter 5. The flat plate portion is provided with a connecting hole for the screw structure 81 to pass through. With this structural arrangement, the flat plate portion of the mounting bracket 7 is squeezed and fixed in the limiting groove 57 by the locking nut 82. The mounting bracket 7 designed with a U-shaped structure plays an installation support and fixing role for the electronic counter 5 on the cover shell. The installation force is more stable and has higher tensile and compressive strength. The supporting force is high and can be used multiple times. The installation of the electronic counter is convenient and quick, which improves the installation efficiency and is also convenient for subsequent disassembly and maintenance.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
