Description

The residual current circuit breaker that has the break-make indicating device

Technical field

The utility model relates to a kind of residual current circuit breaker that has the break-make indicating device that is used for the identification of residual current circuit breaker break-make.

Background technology

Existing residual current circuit breaker generally includes housing, rotating axis component; rotating axis component is provided with buckle structure and driven by the switch handle; under the effect of switch handle; the rotating axis component contact-actuating is connected circuit; and when in circuit, residual current being arranged; the buckle structure action, rotating axis component resets and the contact-actuating open circuit, thereby plays earth leakage protective effect.But no matter this residual current circuit breaker is being connected or off-state, and all stateless shows, whether charged generation is judged by accident to it to cause the user of service easily, thereby increases the danger of its use.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, the residual current circuit breaker that has the break-make indicating device that can intuitive judgment residual current circuit breaker on off operating mode.

For achieving the above object, the technical solution adopted in the utility model is: a kind of residual current circuit breaker that has the break-make indicating device, comprise housing and rotating axis component, at described housing one side sidewall the break-make indicating device is housed, this break-make indicating device is by support, swing arm, swing arm resetting device and push rod are formed, described swing arm by pivotal mounting in described support, offer indicating window at the housing top cover, one end of described swing arm is positioned at described indicating window inboard and indicates the break-make sign, the other end of swing arm is with described push rod one end in contact or be connected, and the push rod other end then contacts with the projection that is installed on described rotating axis component.

The beneficial effects of the utility model are: because residual current circuit breaker is equipped with the break-make indicating device, when its rotating axis component moves because of external force, can drive the swing arm swing by push rod, when the rotating axis component contact-actuating is on off operating mode, driving swing arm simultaneously exposes in the indicating window of a top of the trellis the corresponding sign in its end, it judges that the residual current circuit breaker state is intuitive and reliable, and structure is also fairly simple.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model has the residual current circuit breaker of break-make indicating device, comprise housing 1 and rotating axis component 2, at described housing 1 one side sidewalls the break-make indicating device is housed, this break-make indicating device is by support 3, swing arm 4, swing arm resetting device and push rod 5 are formed, described swing arm 4 by pivotal mounting in described support 3, offer the indicating window (not shown) at the housing top cover, one end of described swing arm 4 is positioned at described indicating window inboard and indicates break-make sign 41, referring to Fig. 3, Fig. 4, the other end of swing arm 4 is with described push rod 5 one end in contact or be connected, and push rod 5 other ends then contact with the projection 21 that is installed on described rotating axis component 2.

In Fig. 1, Fig. 2, described swing arm resetting device is a torsion spring 6, and this torsion spring 6 is loaded on described support 3, and torsion spring 6 one ends are fixed in support 3, and the other end is pressed in an end of described swing arm 4 contact push rods 5.Described support 3 is provided with sliding sleeve 31, and described push rod 5 is located in the described sliding sleeve 31.

Described swing arm resetting device also can be for being enclosed within the spring on the described push rod 5, and this moment, the end of push rod 5 was connected the end of swing arm 4, so that push rod 5 when resetting under spring action, drives swing arm 4 and resets.

As shown in Figure 1 and Figure 2, be provided with interlocking part 32 below described support 3, and be provided with corresponding caulking groove 11 at described housing 1 inboard correspondence position, described break-make indicating device is installed on the described housing 1 by this interlocking part 32.

Break-make indicating device of the present utility model both can be installed on single-phase residual current circuit breaker, as shown in Figure 3, also can be installed on the three-phase residual current circuit breaker, as shown in Figure 4.Break-make indicating device of the present utility model also can adopt other similar structures, as being provided with operative gear at swing arm one end, and is provided with tooth bar on push rod, makes swing arm swing etc. by the rack drives gear.

The operation principle of the utility model break-make indicating device: the parts rotating shaft 2 on the residual current circuit breaker, under the effect of mechanism arrangement power, with the axle on the rotating axis component is that the center rotates, promote push rod 5 moving linearlies, drive swing arm 4 and pivot, reach the purpose of the operating state that shows residual current circuit breaker energized or deenergization.

Wherein, when residual current circuit breaker was in the close position, as shown in Figure 1, rotating shaft projection 21 and push rod 5 are become to contact and promote push rod 5 by released state did rectilinear motion forward.The break-make sign 41 that is installed on the support 3 is subjected under the effect of push rod 5 thrusts, is that the center rotates with the axle.When rotating shaft rotates to certain angle, when the straight-line displacement of push rod 5 reaches certain stroke, break-make sign 41 will rotate a certain angle, from the indication window of top cover see for green, promptly residual current circuit breaker is a "on" position.

When having residual current to produce in the circuit, as shown in Figure 2, rotating shaft projection 21 will reset under the effect of its external force (mechanism arrangement power), and rotating shaft this moment projection 21 is in released state with push rod 5.And break-make sign 41 is subjected to spring force (when residual current circuit breaker is closed, under the effect of push rod 5, torsion spring 6 pressurizeds and the energy storage that produces) promotion under, get back to original position, push rod 5 is also got back to original position simultaneously, from the indication window of residual current circuit breaker see for red, promptly switch is an off-state.This moment, circuit disconnected, protected personal safety, avoids fire, protection equipment, exempted from the purpose of destruction thereby reach.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection range that all any improvement done based on the utility model or modification all belong to the utility model claim.
