Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker safety baffle mechanism and a frame circuit breaker. Background Technology

[0002] The existing drawer-type frame circuit breaker uses a non-linear, angled, inclined push mechanism to control the safety baffle's movement. In actual operation, the force direction can easily deflect, causing the safety baffle push mechanism and the safety baffle to scrape and jam, resulting in malfunctions such as uneven or even jammed safety baffle movement. This directly affects the product's stability and safety. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a circuit breaker safety baffle mechanism, which mainly solves the technical problem that the safety baffle pushing structure in the existing technology is prone to force direction deflection during actual pushing, resulting in scraping and jamming between the safety baffle pushing structure and the safety baffle.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A circuit breaker safety baffle mechanism includes a drawer bottom plate and a safety baffle. The safety baffle is configured to have a first state position and a second state position on the drawer bottom plate that can be switched along a straight line. A plurality of conductors are provided on the drawer bottom plate, and a plurality of through holes are provided on the safety baffle. When the safety baffle is switched to the first state position, each through hole is aligned with each conductor so that each circuit breaker insert can be inserted into the corresponding conductor. When the safety baffle is switched to the second state position, each through hole is staggered from each conductor to prevent the circuit breaker insert from being inserted into the conductor. A safety baffle pushing structure is installed on the drawer bottom plate for controlling the linear switching of the safety baffle between the first state position and the second state position, and the pushing direction of the safety baffle pushing structure is parallel to the linear movement direction of the safety baffle.

[0006] Furthermore, it also includes a drawer frame in which the circuit breaker body is slidably mounted. When the circuit breaker body slides into place relative to the drawer bottom plate, the safety baffle push structure is configured to control the safety baffle to switch to the first state position under the action of the external force applied by the circuit breaker body. When the circuit breaker body is pulled away from the drawer bottom plate, the external force applied by the circuit breaker body to the safety baffle push structure is released, and the safety baffle push structure then controls the safety baffle to automatically reset and switch to the second state position.

[0007] Furthermore, the safety baffle includes a first baffle and a second baffle that slide on the bottom plate of the drawer. The first baffle and the second baffle are stacked together. The first baffle has a plurality of first through holes, and the second baffle has a plurality of second through holes. Each first through hole and each corresponding second through hole are configured to cooperate with each other to form a through hole when aligned and to align with the corresponding conductor on the bottom plate of the drawer.

[0008] Furthermore, the safety baffle pushing structure includes two pushing components fixed to the left and right sides of the drawer bottom plate. The two pushing components are respectively connected to the first baffle and the second baffle. The first baffle and the second baffle are configured to move closer to each other in a straight line under the control of the two pushing components until the corresponding first through hole, second through hole and conductor are aligned one by one, thereby switching the safety baffle to the first state position, or move away from each other until the corresponding first through hole, second through hole and conductor are staggered one by one, thereby switching the safety baffle to the second state position.

[0009] Furthermore, the propulsion assembly includes a base with a groove on the base. A sliding push block is slidably disposed in the groove, and an elastic element is provided between the base and the sliding push block to elastically abut against the sliding push block. The sliding push block has a connecting part for connecting the corresponding first baffle or second baffle, and also has a guide wedge surface. The circuit breaker body has a pressing part. When the circuit breaker body slides into position relative to the drawer bottom plate, the pressing part presses against the guide wedge surface, causing the two sliding push blocks to move synchronously in a straight line. This drives the first baffle and the second baffle to move in opposite directions in a straight line until the corresponding first through hole, second through hole, and conductor are aligned one by one, so that the circuit breaker insert can be inserted into the corresponding conductor. When the circuit breaker body is pulled away from the drawer bottom plate, the pressing part releases its pressing engagement with the guide wedge surface, and the sliding push block automatically resets under the elastic force of the elastic element. This drives the first baffle and the second baffle to move away from each other until the corresponding first through hole, second through hole, and conductor are misaligned to prevent the circuit breaker insert from being inserted into the corresponding conductor.

[0010] Furthermore, the drawer bottom plate is installed on the drawer frame, and the circuit breaker body includes a switch body with several circuit breaker inserts installed and a sliding plate located on both sides of the switch body and slidably connected to the drawer frame. The pressing part is located on the sliding plate and corresponds to the wedge-shaped surface on the sliding push block.

[0011] Furthermore, the elastic element is a compression spring, one end of the groove on the base is open and the other end is closed. The sliding push block is slidably limited in the groove by the limiting structure, and the sliding direction of the sliding push block in the groove is consistent with the movement direction of the first baffle and the second baffle. The connecting part of the sliding push block extends upward out of the groove and is connected to the corresponding first baffle or second baffle. The sliding push block has an extension that extends out of the open end of the groove, and a guide wedge surface is provided on the extension.

[0012] Furthermore, the ends of the first baffle and the second baffle are respectively provided with a first avoidance notch and a second avoidance notch for avoiding the propulsion assembly on the opposite side.

[0013] Furthermore, a sliding mounting position is provided on the bottom plate of the drawer, and the first baffle and the second baffle are slidably disposed in the sliding mounting position. Several limiting ribs are provided on the two side walls of the sliding mounting position to limit the first baffle and the second baffle within the sliding mounting position.

[0014] Furthermore, a limiting guide protrusion is provided on the bottom plate of the drawer, and a first guide groove and a second guide groove are respectively provided on the first baffle and the second baffle. The limiting guide protrusion fits through the first guide groove and the second guide groove on the first baffle and the second baffle and cooperates with each other to form a limiting guide structure, thereby guiding and limiting the lateral movement of the first baffle and the second baffle relative to the bottom plate of the drawer.

[0015] Furthermore, the sides of the first baffle and the second baffle are respectively provided with a number of first arc contact protrusions and second arc contact protrusions corresponding to the sidewalls of the sliding embedding positions. The frictional resistance of the first baffle and the second baffle sliding laterally in the sliding embedding positions is reduced by the abutting cooperation between the first arc contact protrusions and the second arc contact protrusions and the sidewalls of the sliding embedding positions.

[0016] Based on the same inventive concept, this utility model also provides a frame circuit breaker, including the circuit breaker safety baffle mechanism described above.

[0017] The above technical solution has the following advantages or beneficial effects:

[0018] In the circuit breaker safety baffle mechanism and frame circuit breaker described in this utility model, the safety baffle pushing structure used to control the movement of the safety baffle is a linear thrust type pushing structure. Since the thrust direction of the safety baffle pushing structure is parallel to the linear movement direction of the safety baffle, it helps to avoid the problem of scraping and jamming between the safety baffle pushing structure and the safety baffle when the safety baffle is in motion, making the movement of the safety baffle smoother and thus improving the reliability of the safety baffle.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Please refer to the appendix. Figure 1 To be continued Figure 10 An embodiment of this utility model provides a circuit breaker safety baffle mechanism, including a drawer bottom plate 1 and a safety baffle 2. The safety baffle 2 is configured to have a first state position and a second state position on the drawer bottom plate 1 that can be switched along a straight line. A plurality of conductors 11 are provided on the drawer bottom plate 1, and a plurality of through holes are provided on the safety baffle 2. When the safety baffle 2 is switched to the first state position, each through hole is aligned with each conductor 11 so that each circuit breaker insert 3 can be inserted into the corresponding conductor 11. When the safety baffle 2 is switched to the second state position, each through hole is staggered from each conductor 11 to prevent the circuit breaker insert 3 from being inserted into the conductor 11. A safety baffle pushing structure is installed on the drawer bottom plate 1 for controlling the linear switching of the safety baffle 2 between the first state position and the second state position. The pushing force of the safety baffle pushing structure is in a straight line direction, and the pushing force direction of the safety baffle pushing structure is parallel to the linear movement direction of the safety baffle 2. It is understood that in this embodiment, the safety baffle propulsion structure used to control the movement of the safety baffle 2 is a linear thrust propulsion structure. Since the thrust direction of the safety baffle propulsion structure is parallel to the linear movement direction of the safety baffle 2, it helps to avoid the problem of scraping and jamming between the safety baffle propulsion structure and the safety baffle 2 when the safety baffle propulsion structure moves, making the movement switching of the safety baffle 2 more stable and smooth, thereby improving the reliability of the movement of the safety baffle 2.

[0033] Please refer to the appendix. Figure 1 Appendix Figure 2 Attached Figures Figure 8 In one preferred embodiment, the circuit breaker safety baffle mechanism further includes a circuit breaker body 4. When the circuit breaker body 4 slides into position relative to the drawer bottom plate 1, the safety baffle pushing structure is configured to control the safety baffle 2 to switch to a first state position under the external force applied by the circuit breaker body 4. When the circuit breaker body 4 is pulled away from the drawer bottom plate 1, the external force applied to the safety baffle pushing structure is released, and the safety baffle pushing structure controls the safety baffle 2 to automatically reset and switch to a second state position. In this embodiment, the pushing action of the safety baffle pushing structure is associated with whether the circuit breaker body 4 slides into position relative to the drawer bottom plate 1. When the circuit breaker body 4 slides into position relative to the drawer bottom plate 1, the safety baffle pushing structure can automatically control the safety baffle 2 to switch to the first state position, thereby releasing the blocking effect of the safety baffle 2 so that the circuit breaker insert 3 can be inserted into the conductor 11. When the circuit breaker body 4 is pulled out, the safety baffle pushing structure can control the safety baffle 2 to reset to the second state position, thereby regenerating the blocking effect. Meanwhile, since the safety baffle pushing structure is directly driven by the circuit breaker body 4, it forms a strong correlation with the swing-in action of the circuit breaker body 4, making its driving action stable and reliable. After the circuit breaker body 4 is swinged out, the safety baffle pushing structure can reliably and automatically reset and drive the safety baffle 2 to switch to the second state to form a function of preventing accidental electric shock.

[0034] Please refer to the appendix. Figure 1 To be continued Figure 10 In one preferred embodiment, the safety baffle 2 includes a first baffle 21 and a second baffle 22 that slide on the drawer bottom plate 1. The first baffle 21 and the second baffle 22 are stacked together. The first baffle 21 has a plurality of first through holes 211 and the second baffle 22 has a plurality of second through holes 221. Each first through hole 211 and each corresponding second through hole 221 are configured to cooperate with each other to form a through hole when aligned and are aligned one by one with the corresponding conductors 11 on the drawer bottom plate 1. Preferably, the safety baffle pushing structure includes two pushing components 5 fixed to the left and right sides of the drawer bottom plate 1. The two pushing components 5 are respectively connected to the first baffle 21 and the second baffle 22. The first baffle 21 and the second baffle 22 are configured to move closer to each other in a straight line under the control of the two pushing components 5 until the corresponding first through hole 211, second through hole 221 and conductor 11 are aligned one by one, thereby switching the safety baffle 2 to the first state position, or move away from each other until the corresponding first through hole 211, second through hole 221 and conductor 11 are staggered one by one, thereby switching the safety baffle 2 to the second state position. In this embodiment, the safety baffle 2 is formed by the combination of the first baffle 21 and the second baffle 22. During operation, both the first baffle 21 and the second baffle 22 need to move to the designated position so that the first through hole 211 and the second through hole 221 can be completely overlapped and correspond to the conductor 11, so that the circuit breaker insert 3 can be accurately inserted into the conductor 11. During this process, if any baffle fails to move into position, the circuit breaker insert 3 will not be able to be inserted smoothly. This also requires that the circuit breaker body 4 can only control the first through hole 211 on the first baffle 21 and the second baffle 22 to be completely aligned with the corresponding second through hole 221 after it is accurately and smoothly rocked into position. Then the circuit breaker insert 3 is inserted into the conductor 11 to ensure connection stability.

[0035] Please refer to the appendix. Figure 1 To be continued Figure 10In one preferred embodiment, the propulsion assembly 5 includes a base 51, on which a groove 511 is formed. A sliding push block 52 is slidably disposed in the groove 511. An elastic member 53 is provided between the base 51 and the sliding push block 52 to elastically abut against the sliding push block 52. The sliding push block 52 is provided with a connecting part 521 for connecting to the corresponding first baffle 21 or second baffle 22. The sliding push block 52 is also provided with a guide wedge surface 522. The circuit breaker body 4 is provided with a pressing part 43. When the circuit breaker body 4 slides into position relative to the drawer bottom plate 1, the pressing part presses against the guide wedge surface 522, so that the two sliding push blocks 52 move synchronously in a straight line. This causes the first baffle 21 and the second baffle 22 to move in a straight line toward each other until the corresponding first through hole 211, second through hole 221 and conductor 11 are aligned one by one, so that the circuit breaker insert 3 can be inserted into the corresponding conductor 11. When the circuit breaker body 4 is pulled away from the drawer bottom plate 1, the pressing part 43 releases its pressing engagement with the guide wedge surface 522, and the sliding push block 52 automatically resets under the elastic force of the elastic element 53, thereby causing the first baffle 21 and the second baffle 22 to move away from each other until the corresponding first through hole 211, second through hole 221 and conductor 11 are staggered to prevent the circuit breaker insert 3 from being inserted into the corresponding conductor 11. In this embodiment, the base 51 of the push assembly 5 is directly fixedly installed on both sides of the drawer bottom plate 1. This arrangement ensures that the push assembly 5 will not cause unnecessary interference to the circuit breaker body 4 when it is rocked into the drawer bottom plate 1, thus improving the smoothness of the movement of the circuit breaker body 4. At the same time, the fixed installation of the push assembly 5 to the drawer bottom plate 1 can also improve the driving stability of the push assembly 5 on the first baffle 21 and the second baffle 22. The circuit breaker body 4 does not directly drive the first baffle 21 and the second baffle 22, but only triggers the push assembly 5. The sliding push block 52 on the push assembly 5 then pushes the first baffle 21 and the second baffle 22 by sliding along a straight line. This greatly improves the linear movement stability and smoothness of the first baffle 2 and the second baffle 22, thereby improving the operational reliability of the safety baffle 2.

[0036] Please refer to the appendix. Figure 7 Appendix Figure 8 In one preferred embodiment, the drawer bottom plate 1 is mounted on the drawer frame 6. The circuit breaker body 4 includes a switch body 41 with a plurality of circuit breaker inserts 3 and a sliding plate 42 located on both sides of the switch body 41 and slidably connected to the drawer frame 6. A pressing part is provided on the sliding plate 42 and corresponds to the wedge-shaped surface 522 on the sliding push block 52. With this configuration, the inward and outward rocking motion of the circuit breaker body 4 can be converted into the left and right lateral movement of the first baffle 21 and the second baffle 22, thereby controlling the first baffle 21 and the second baffle 22 to move and switch between the blocking position and the avoidance position.

[0037] Please refer to the appendix. Figure 4 To be continued Figure 6 In one preferred embodiment, the elastic element 53 is a compression spring. One end of the groove 511 on the base 51 is open, and the other end is closed. The sliding push block 52 is slidably confined within the groove 511 by a limiting structure. The sliding direction of the sliding push block 52 within the groove 511 is consistent with the movement direction of the first baffle 21 and the second baffle 22. The connecting portion 521 of the sliding push block 52 extends upwards out of the groove 511 and connects to the corresponding first baffle 21 or second baffle 22. The sliding push block 52 has an extension extending out of the open end of the groove 511, and a guide wedge surface 522 is provided on the extension. Further, the ends of the first baffle 21 and the second baffle 22 are respectively provided with a first avoidance notch 212 and a second avoidance notch 222 for avoiding the propulsion assembly 5 on the opposite side.

[0038] Please refer to the appendix. Figure 1 To be continued Figure 3 and attached Figure 8 Appendix Figure 9 In one preferred embodiment, a sliding mounting position is provided on the drawer bottom plate 1. The first baffle 21 and the second baffle 22 are slidably disposed in the sliding mounting position, and several limiting ribs 12 are provided on the two side walls of the sliding mounting position to limit the first baffle 21 and the second baffle 22 within the sliding mounting position. Further, a limiting guide protrusion 13 is provided on the drawer bottom plate 1, and a first guide groove 213 and a second guide groove 223 are respectively provided on the first baffle 21 and the second baffle 22. The limiting guide protrusion 13 fits through the first guide groove 213 and the second guide groove 223 on the first baffle 21 and the second baffle 22 and cooperates with each other to form a limiting guide structure, thereby guiding and limiting the lateral movement of the first baffle 21 and the second baffle 22 relative to the drawer bottom plate 1, which helps to improve the stability and smoothness of the movement of the first baffle 21 and the second baffle 22 relative to the drawer bottom plate 1.

[0039] Please refer to the appendix. Figure 9 In one preferred embodiment, the sides of the first baffle 21 and the second baffle 22 are respectively provided with a plurality of first arc contact protrusions 214 and second arc contact protrusions 224 corresponding to the sidewalls of the sliding mounting positions. The first arc contact protrusions 214 and the second arc contact protrusions 224 abut against the sidewalls of the sliding mounting positions to reduce the frictional resistance of the first baffle 21 and the second baffle 22 sliding laterally in the sliding mounting positions, thereby improving the stability and smoothness of the movement of the first baffle 21 and the second baffle 22 relative to the drawer bottom plate 1.
