Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to an anti-deformation wiring board for a circuit breaker. Background Art

[0002] Circuit breakers are essential equipment in power systems. They can control and protect various AC and DC circuits and power conversion. The installation of circuit breakers in power systems requires terminal blocks, which are used to fix circuit breakers and install them in distribution boxes or switch boxes, making them prone to displacement or falling off.

[0003] The existing terminal block for installing a circuit breaker has few bending points, resulting in concentrated force. It is easy to bend and deform after receiving external pressure, causing problems affecting the installation stability of the circuit breaker. Therefore, an anti-deformation terminal block for a circuit breaker is proposed to better disperse the stress, avoid concentrated force, improve its anti-deformation property after assembling the circuit breaker, and ensure the stability of the circuit breaker after installation.

[0005] The technical solution adopted by the utility model to solve the technical problem is an anti-deformation wiring board for a circuit breaker, comprising:

[0006] The line board part is used to install the circuit breaker;

[0007] A mounting portion, arranged on the line plate portion;

[0008] The reinforcement part is arranged on the line plate part.

[0009] By adopting the above technical solution, a set of terminal board components with high use strength and good deformation resistance is provided for the assembly of circuit breaker through the components composed of the wire board part, the reinforcement part and the installation part.

[0010] Specifically, the line plate portion includes:

[0011] Alumina support bars for supporting the circuit breaker.

[0012] By adopting the above technical solution, the alumina support strip has better use strength and insulation, so that the installation stability of the circuit breaker is better.

[0013] Specifically, the reinforcement part includes:

[0014] The first bending point is arranged on the alumina support bar;

[0015] The second bending point is arranged on the alumina support bar;

[0016] The third bending point is arranged on the alumina support bar.

[0017] By adopting the above technical solution, through the bending setting of the first bending point, the second bending point and the third bending point on the alumina support bar, the alumina support bar can be more easily resistant to external forces, and can better disperse stress, avoid concentrated force, improve its deformation resistance after assembling the circuit breaker, and ensure the stability of the circuit breaker after installation.

[0018] Specifically, the installation part includes:

[0019] There are multiple groups of bolt mounting holes, and the multiple groups of bolt mounting holes are opened at equal distances through the middle of the alumina support strip;

[0020] The card edge is set on the alumina support bar.

[0021] By adopting the above technical solution, the alumina support bar can be connected to the external device or bracket by bolts through the bolt mounting holes, and the clamping edge can help the clamping slot on the back of the circuit breaker to be clamped and installed.

[0022] Specifically, the first bending point, the second bending point and the third bending point are each arranged in two groups, and the two groups of the first bending point, the second bending point and the third bending point are symmetrically arranged along both sides of the bolt mounting hole.

[0023] By adopting the above technical solution, the supporting stress of the whole wiring board is dispersed through six groups of symmetrical bending points. It is not easy to deform or bend when subjected to external force, so it has better deformation resistance.

[0024] The beneficial effects of the utility model are as follows: through the components consisting of the wire plate part, the reinforcement part and the installation part, a set of terminal board components with high use strength and good deformation resistance is provided for the assembly of the circuit breaker. The alumina support strip has good use strength and insulation, so that the installation stability of the circuit breaker is better. Through the bending arrangement of the first bending point, the second bending point and the third bending point on the alumina support strip, the alumina support strip is easier to resist external force, and can better disperse stress, avoid concentrated force, improve its deformation resistance after assembling the circuit breaker, ensure the stability of the circuit breaker after installation, disperse the support stress of the overall terminal board, and it is not easy to deform or bend when subjected to external force, so it has better deformation resistance, and solves the problem that the terminal board used for the installation of the existing circuit breaker has few bending points, resulting in concentrated force, and is easy to bend and deform after receiving external pressure, which affects the installation stability of the circuit breaker.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] In order to improve the deformation resistance of the terminal block after the circuit breaker is installed, Figure 1-4 As shown, the anti-deformation terminal block for a circuit breaker according to the utility model comprises:

[0033] The line board part is used to install the circuit breaker;

[0034] The mounting portion 3 is arranged on the line plate portion;

[0035] The reinforcement part 2 is arranged on the line plate part.

[0036] The line plate portion comprises:

[0037] Alumina support bar 1, used to support the circuit breaker.

[0038] The mounting portion 3 comprises:

[0039] There are multiple groups of bolt mounting holes 301, and the multiple groups of bolt mounting holes 301 are opened at equal distances through the middle of the alumina support bar 1;

[0040] The clamping edge 302 is disposed on the alumina support bar 1 .

[0041] When in use, the mounting portion 3 is used to mount the line plate portion on external equipment or brackets, and to assemble the circuit breaker on the line plate portion, and the reinforcing portion 2 increases the use strength and anti-deformation effect of the overall structure of the line plate portion.

[0042] In order to provide the wiring board with high strength and deformation resistance, for example, Figure 1 ,2 As shown, the utility model also includes that the reinforcement part 2 includes:

[0043] The first bending point 201 is arranged on the alumina support bar 1;

[0044] The second bending point 202 is arranged on the alumina support bar 1;

[0045] The third bending point 203 is disposed on the alumina support bar 1 .

[0046] The first bending point 201 , the second bending point 202 and the third bending point 203 are each arranged in two groups, and the two groups of the first bending point 201 , the second bending point 202 and the third bending point 203 are symmetrically arranged along both sides of the bolt installation hole 301 .

[0047] When in use, the six groups of symmetrically arranged first bending points 201, second bending points 202 and third bending points 203 can better disperse the pressure on the alumina support bar 1, thereby improving the anti-deformation effect of the circuit breaker on the alumina support bar 1 after assembly.

[0048] When the utility model is in use, the bolt is passed through the bolt installation hole 301 to install it on the electrical cabinet or the power equipment that needs to be assembled with the circuit breaker, and then the back card slot of the circuit breaker to be assembled is aligned with the card edge 302, and pressure is applied to the front of the circuit breaker so that the card slot on the back of the circuit breaker is stuck on the card edges 302 at the top and bottom of the alumina support bar 1 to achieve the assembly of the circuit breaker. The six groups of bending points composed of the first bending point 201, the second bending point 202 and the third bending point 203 symmetrically arranged above and below can effectively ensure the bending resistance of the alumina support bar 1, disperse the force of the alumina support bar 1, and ensure that the alumina support bar 1 is not easy to bend and deform after being subjected to the weight pressure of the circuit breaker assembly, thereby ensuring the stability of the installation and use of the circuit breaker and enabling the circuit breaker to better cooperate with the power equipment.
