Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 to 5, in the present embodiment, the direction a is upward, the direction B is downward, the direction C is leftward, and the direction D is rightward. The embodiment provides a monopole miniature circuit breaker combination, including two monopole breaker bodies that connect side by side to two monopole breaker bodies all can connect through the buckle split. In addition, the up side and the downside of the handle 5 of two monopole breaker bodies all are equipped with recess 2, and this equipment still includes the checkpost 3 of cross section "V" style of calligraphy, and the checkpost includes first splint 6 and second splint 7, first splint 6 and second splint 7 are articulated and are equipped with torsional spring 8 through pivot 8 for the pulling is tight with first splint 6 and second splint 7 toward centre gripping, during the installation, torsional spring 8 can cup joint in the pivot 8, a foot of torsional spring 8 is connected first splint 6, another foot is connected second splint 7 to provide the clamping-force between first splint 6 and second splint 7 through torsional spring 8. In addition, the edge of the first clamping plate 6 and the edge of the second clamping plate 7 are provided with clamping edges 4 which are clamped into the grooves.

The specific installation method of the equipment comprises the following steps:

after the two single-pole circuit breaker bodies are arranged side by side and all the handles 5 face upwards or downwards, the first clamping plate 6 and the second clamping plate 7 are opened against the elastic force of the torsion spring 8, then the clamping edge of the first clamping plate 6 is clamped into one of the grooves, and the edge of the second clamping plate 7 is clamped into the other groove. And finally, loosening is carried out, and the two clamping edges are always clamped in the corresponding grooves under the action of the torsion spring 8, so that the connection of the clamp and the handle is completed. Because the torque required for opening the first clamping plate 6 and the second clamping plate 7 is small and is far less than the torque required for forcibly clamping into the groove in the prior art, the clamping device is more labor-saving and is beneficial to installation.

In this embodiment, the first clamping plate 6 and the second clamping plate 7 are made of aluminum alloy, the aluminum alloy is hard, and all the handles are not deformed when the first clamping plate 6 and the second clamping plate 7 are clamped. In addition, in order to make the clip 3 tightly clip into the two grooves 2 and ensure the connection firmness of the clip 3 and the two handles 5, the present embodiment is reinforced by the following structure:

recess 2 all inclines toward the end of handle 5, and two recesses 2 all extend toward the direction of checkpost 3, and the card is then forming the connected mode of interior knot in going into recess 2, and interior knot mode is difficult to appear not hard up, further guarantees the steadiness of connecting. The width of the groove 2 is the same as that of the clamping edge 4. Checkpost 3 is the same with the width homogeneous phase of recess 2, guarantees that joint limit 4 can not appear the condition of rocking in recess 2 for connect inseparabler.

As a further improvement of this embodiment, the first clamping plate 6 and the second clamping plate 7 have reinforcing ribs extending along the length direction on the side surfaces thereof for enhancing the bending resistance of the first clamping plate 6 and the second clamping plate 7, and a stop (not shown in the drawings) can be disposed on the inner sides of the first clamping plate 6 and the second clamping plate 7, the stop abutting against the side end of the handle, so as to limit the clip and prevent the clip from moving along the length direction thereof and separating from the handle when being affected by an external force.

The single-pole circuit breaker body in this equipment is equipped with two and two single-pole circuit breaker bodies all can connect through the buckle split. And the length of the clip 3 is greater than the sum of the lengths of the two handles 5. The length of checkpost 3 is enough to live two handle 5 equal parcels, guarantees two handle 5's joint strength, connects more firmly. In addition, the device can not only realize the connection of the handle 5, but also realize the interconversion between the two-pole miniature circuit breaker combination and the single-pole circuit breaker. The method comprises the following specific operations: open checkpost 3 and take off the back, rethread buckle with two single-pole circuit breaker body splits, alright in order to use every single-pole circuit breaker body alone.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
