Description

Technical Field

[0001] The utility model application relates to the technical field of air circuit breakers, in particular to a household air circuit breaker switch available for multiple circuits. Background Art

[0002] An air circuit breaker is a switch that automatically disconnects as long as the current in the circuit exceeds the rated current. As a very important electrical appliance in low-voltage power distribution networks and electric traction systems, it integrates control and multiple protection functions. It can not only contact and disconnect circuits, but also protect circuits or electrical equipment from circuit breaks, severe overloads and undervoltages. It can also be used to start motors infrequently.

[0003] Since multi-line household air circuit breaker switches have more wiring when in use, the arrangement of the wires at the upper and lower ends of the switch after wiring is relatively random, unstable and easy to affect each other. In addition, since multi-line household air circuit breaker switches require multiple insulating handles, when they need to be opened or closed uniformly, they need to be turned one by one, which is more laborious. Summary of the invention

[0004] In order to solve the problems that the wiring arrangement of the existing multi-line household air circuit breaker is not stable when in use and it is inconvenient to uniformly move the insulating handle, the utility model provides a multi-line household air circuit breaker to solve the above problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A household air circuit breaker switch available for multiple lines comprises a circuit breaker switch body, a wiring slot and an insulating handle, wherein a support frame is sleeved on the circuit breaker switch body outside the wiring slot, a plurality of clamping blocks are fixed relatively equidistantly at the upper and lower ends of opposite sides of two support frames, support rods are symmetrically and slidably sleeved on both sides of the two support frames, and support blocks are fixed to the front and rear ends of the support rods, the side surfaces of each support block are fixed to the side walls of the circuit breaker switch body, a spring is sleeved on the support rod between the outer side of the support frame and the support block, and both ends of the spring are respectively fixed to the support frame and the support block, and a pushing component is arranged on the bottom surface of the insulating handle.

[0007] Furthermore, the pushing assembly includes a fixed rod, a sliding side plate and a horizontal lever. Fixed rods are fixed to the sides of the circuit breaker body on both sides of the insulating handle, and sliding side plates are slidably sleeved on the fixed rods. Sliding grooves that cooperate with the fixed rods are opened inside the sliding side plates, and a horizontal lever is fixed between the two sliding side plates.

[0008] Furthermore, the two support frames are both configured as rectangular frames that match the circuit breaker body, and each group of two clamping blocks are configured as arcs in a relative manner, and each group of two clamping blocks correspond to the wiring slots.

[0009] Furthermore, inner slide bars are fixed at the middle of both ends of the front of the rear support frame, and front sleeves are fixed at the middle of both ends of the front of the front support frame, and each inner slide bar is slidably inserted inside the front sleeve.

[0010] Furthermore, a second spring is sleeved on the inner sliding rod between the two support frames, and both ends of the second spring are fixed on the support frames.

[0011] Furthermore, the front sleeve is configured as a transversely placed hollow "T" shape that cooperates with the inner sliding rod, and the support frame is provided with a sliding hole that cooperates with the support rod and the inner sliding rod.

[0012] Furthermore, the two fixing rods are both arranged in a transversely placed "T" shape, and handles are fixed to the outer bottoms of the two sliding side panels.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, through the external movable support frame, after wiring, the wires can be positioned and reinforced by two relative clamping blocks, so that the wiring connection is more stable. Two fingers are placed behind the two sides of the front sleeve and the inner slide rod is pressed to open the two support frames, which is more convenient and labor-saving during operation. It solves the problem that the wiring arrangement of the existing multi-line household air circuit breaker is not stable when in use, and makes the wires more stable and orderly after the wiring is completed.

[0015] 2. In the utility model, a movable horizontal lever is provided. When the insulating handles need to be moved uniformly, the horizontal lever is first moved to the side of the insulating handles, and the insulating handles can be uniformly moved by pulling the horizontal lever, thereby solving the problem of the inconvenience of uniformly moving the insulating handles when using the existing household air circuit breaker switches with multiple lines, and improving the convenience of using the air circuit breaker switches.

A support frame 4 is sleeved on the circuit breaker switch body 1 outside the wiring slot 2. The two support frames 4 are both set as rectangular frames that match the circuit breaker switch body 1. Each group of two clamping blocks 5 are set in an arc shape in a relative manner. Each group of two clamping blocks 5 corresponds to the wiring slot 2. A plurality of clamping blocks 5 are fixed relatively equidistantly at the upper and lower ends of the opposite sides of the two support frames 4. Support rods 6 are symmetrically slidably sleeved on both sides of the two support frames 4, and support blocks 7 are fixed at the front and rear ends of the support rods 6. Each The sides of the support block 7 are fixed to the side walls of the circuit breaker body 1, and a spring 8 is sleeved on the support rod 6 between the outer side of the support frame 4 and the support block 7, and both ends of the spring 8 are respectively fixed to the support frame 4 and the support block 7. An inner slide bar 10 is fixed to the middle of the two ends of the front of the rear support frame 4, and a front sleeve 9 is fixed to the middle of the two ends of the front of the front support frame 4. Each inner slide bar 10 is slidably inserted into the front sleeve 9, and a spring 2 11 is sleeved on the inner slide bar 10 between the two support frames 4, and both ends of the spring 2 11 are fixed to the support frame 4, and a pushing component is provided on the bottom surface of the insulating handle 3.

[0024] Specifically, when wiring, place the fingers on both sides on the rear side of the protruding part in front of the front sleeve 9 and press the inner slide bar 10 to make the two support frames 4 move relative to each other and stretch the fixing rod 12, while compressing the spring 1 8. After the clamping blocks 5 are separated, insert the wires into the wiring slot 2 and tighten them. After fixing, loosen the front sleeve 9 and the inner slide bar 10, so that the support frame 4, under the push of the spring 1 8 and the spring 2 11, drives the clamping block 5 to clamp the wires for positioning and reinforcement.

[0025] As an optimization solution, Figure 2 and Figure 4 As shown, the pushing assembly includes a fixed rod 12, a sliding side plate 13 and a horizontal lever 15.
