[0038] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0039] Please refer to Figure 1-Figure 5The phase partition 100, the housing 200 and the circuit breaker 1000 provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0040] The phase partition 100 is used to cooperate with the housing 200 of the circuit breaker 1000, and the phase partition 100 includes: an introduction portion 110, a bending portion 120 and an extension portion 130 arranged in sequence along the direction of embedding into the housing 200; wherein the bending portion 120 is arranged at an angle with the introduction portion 110 and the extension portion 130, and an anti-tripping buckle 121 is formed at one end of the bending portion 120 close to the extension portion 130.

[0041] The phase partition 100 can be sequentially embedded into the housing 200 along the direction of the introduction portion 110, the bending portion 120 and the extension portion 130, and the anti-drop buckle 121 can be formed to prevent the phase partition 100 from dropping out, thereby facilitating assembly and ensuring that the phase partition 100 will not easily drop out of the housing 200.

[0042] refer to Figure 1 and Figure 2 The phase partition 100 has a fixed end 101 and an open end 102 that are arranged opposite to each other, and the fixed end 101 is used to cooperate with the housing 200.

[0043] In this embodiment, the cross-sectional area of ​​the fixed end 101 is greater than the cross-sectional area of ​​the open end 102 ; of course, in other embodiments of the present invention, the cross-sectional area of ​​the fixed end 101 may be less than or equal to the cross-sectional area of ​​the open end 102 .

[0044] It should be noted that the direction from the lead-in portion 110 to the extension portion 130 on the phase partition 100 is perpendicular to the direction from the fixed end 101 to the open end 102. During the assembly process, the fixed end 101 will cooperate with the housing 200, while the open end 102 is relatively far away from the housing 200. When embedded, the fixed end 101 of the phase partition 100 is close to the housing 200, and the lead-in portion 110, the bent portion 120 and the extension portion 130 are sequentially in contact with the housing 200 to achieve the embedding operation.

[0045] At the same time, in order to ensure that there will be no misoperation in the assembly of the phase partition 100, an embedded arrow can be provided on the surface of the introduction portion 110, and the direction of the embedded arrow is the embedding direction of the phase partition 100, so as to avoid damage to the housing 200 and the phase partition 100 due to reverse embedding operation due to lack of familiarity of the staff.

[0046] refer to Figure 1-Figure 3 In order to improve the anti-drop performance of the anti-drop buckle 121, an angle α may be formed between the anti-drop buckle 121 and the extension portion 130, wherein 60°≤α≤120°.

[0047] Specifically, the size of α can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115° and 120°, etc., preferably α=90°. Of course, there is no limitation on the specific angle size of α.

[0048] refer to Figure 1-Figure 3 In order to ensure that the connection between the bending portion 120 and the introduction portion 110 does not cause introduction obstruction, a transition slope 122 can be formed at one end of the bending portion 120 close to the introduction portion 110, and an angle β is formed between the transition slope 122 and the introduction portion 110, wherein 135°≤β≤175°.

[0049] Specifically, the size of β can be 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170° and 175°, etc., preferably β=160°. Of course, there is no limitation on the specific angle size of β.

[0050] refer to Figure 1-Figure 3 In order to further improve the embedding efficiency of the phase partition 100, a guide head 111 can be formed at one end of the introduction part 110 away from the bending part 120. The setting of the guide head 111 can reduce the friction resistance existing when the introduction part 110 just contacts the shell 200.

[0051] In this embodiment, the introduction head is in the shape of a cone, and the outer diameter of the entire introduction head gradually decreases in the direction away from the extension portion 130. In addition, inclined surfaces are formed on both sides of the introduction head, and the two inclined surfaces are symmetrically arranged about the center plane of the introduction head.

[0052] Of course, in other embodiments of the present invention, the two sides of the introduction head may be a plane and an inclined plane, or two inclined planes that are not symmetrical about the center plane of the introduction head, and the specific appearance of the introduction head is not limited.

[0053] refer to Figure 1-Figure 3 In order to prevent the phase partition 100 from detaching from the housing 200 in the direction from the fixed end 101 to the open end 102, the phase partition 100 may further include a first limit block 140, the first limit block 140 is located at the fixed end 101 of the introduction part 110, and the first limit block 140 is protruded from the introduction part 110. By forming the first limit block 140, the position stability of the introduction part 110 embedded in the housing 200 can be improved, and the introduction part 110 can be prevented from easily detaching from the housing 200.

[0054] In this embodiment, the first limit block 140 protrudes from both sides of the introduction part 110, and both side surfaces of the first limit block 140 are inclined surfaces, so that the thickness of the first limit block 140 gradually decreases along the direction from the fixed end 101 to the open end 102, and the thickness at the thinnest part is consistent with the thickness of the introduction part 110. At the same time, the first limit block 140 is also connected to the introduction head, which improves the limiting effect on the introduction part 110 while not having a negative impact on the embedding guide of the introduction part 110.

[0055] Similarly, the phase partition 100 may also include a second limit block 150, which is located at the fixed end 101 of the extension part 130. The second limit block 150 is protruding from the extension part 130. By forming the second limit block 150, the position stability of the extension part 130 embedded in the outer shell 200 can be improved, thereby preventing the extension part 130 from easily detaching from the outer shell 200.

[0056] In this embodiment, the second limit block 150 protrudes from the introduction portion 110 from both sides of the extension portion 130, and a forked structure is formed on the second limit block 150, so that the second limit block 150 is forked from the open end 102 to the fixed end 101, and the forked width gradually decreases along the direction from the open end 102 to the fixed end 101.

[0057] It is worth noting that by simultaneously providing the first limit block 140 and the second limit block 150, the matching stability between the introduction part 110 and the extension part 130 and the outer shell 200 can be increased, so that the front and rear sides of the phase partition 100 will not easily detach from the outer shell 200, and the phase partition 100 can be prevented from deflecting when subjected to external force.

[0058] refer to Figure 4 and Figure 5 The embodiment of the utility model further provides a shell 200 for cooperating with the phase partition 100; a receiving groove 210 is formed on the shell 200, and the receiving groove 210 has an introduction section 220, a bending section 230 and an extension section 240 which are connected in sequence, and the bending section 230 is arranged at an angle with the introduction section 220 and the extension section 240 at the same time, and a limiting clamping platform 241 is formed at one end of the extension section 240 close to the bending section 230, the introduction section 220 is used to accommodate the introduction part 110, the bending section 230 is used to accommodate the bending part 120, the extension section 240 is used to accommodate the extension part 130, and the limiting clamping platform 241 is used to resist the anti-dropping buckle 121.

[0059] It should be noted that the width of the opening of the introduction section 220, the bending section 230 and the extension is slightly larger than the thickness of the introduction portion 110, the bending portion 120 and the extension portion 130. In addition, the receiving groove 210 is a structure with a large bottom and a small mouth, so as to accommodate and limit the first limit block 140 and the second limit block 150 on the phase partition 100, so as to prevent the phase partition 100 from being separated from the receiving groove 210 from the bottom of the groove to the groove mouth.

[0060] Furthermore, in order to reduce the process difficulty of the accommodating groove 210, the outer shell 200 includes an upper half shell 201 and a lower half shell 202 that are detachably connected, the extension section 240 is formed on the upper half shell 201, and the bending section 230 and the introduction section 220 are formed on the lower half shell 202, so that the upper half shell 201 and the lower half shell 202 have a staggered structure at the position where the extension section 240 and the bending section 230 are connected to form a limit card platform 241.

[0061] In this embodiment, two receiving grooves 210 are respectively provided on two sides of the housing 200, accommodating a total of four phase partitions 100. Of course, in other embodiments of the present invention, the number of receiving grooves 210 on the housing 200 can also be one, three, six, etc., and the specific number is not limited.

[0062] refer to Figure 5 The embodiment of the utility model also provides a circuit breaker 1000, including a phase partition 100 and a housing 200; wherein the introduction portion 110 is accommodated in the introduction section 220, the bending portion 120 is accommodated in the bending section 230, the extension portion 130 is accommodated in the extension section 240, and the limit card platform 241 is abutted against the anti-trip buckle 121.

[0063] In addition, the circuit breaker 1000 further includes electrical components and fixings mounted on the housing 200. The electrical components are used to transmit electrical signals on the circuit breaker 1000, and the fixings are used to fix the electrical components to prevent the electrical components from being separated from the housing 200 after long-term use. The fixings are mostly detachable structures to facilitate maintenance and replacement of the electrical components.

[0064] In summary, the phase partition 100, the housing 200 and the circuit breaker 1000 provided in the embodiment of the utility model have at least the following advantages:

[0065] (1) By providing the phase partition 100 and the receiving groove 210 with a bent structure, and making the limit clamping platform 241 abut against the anti-dropping buckle 121, the phase partition 100 is prevented from falling off, and the phase partition 100 is ensured not to be easily separated from the housing 200 on the basis of easy assembly;

[0066] (2) By forming a first limit block 140 and a second limit block 150 on the fixed end 101 of the phase partition 100, and the two limit blocks are respectively located at the introduction portion 110 and the extension portion 130, both sides of the phase partition 100 can be firmly embedded in the accommodating groove 210, thereby further improving the relative position stability of the phase partition 100 and the housing 200.
