Description

Circuit breaker with module

Technical Field

The utility model relates to a low-voltage apparatus technical field, concretely relates to take circuit breaker of module.

Background

At present, various accessories are embedded on the middle cover of the molded case circuit breaker, so that the middle cover can have a buckle installation through hole under the condition of meeting the structural requirement of accessory installation. However, as the fastening structure of the accessory is an elastic structure, a larger gap is reserved for the fastening of the accessory in order to facilitate the installation of the accessory. Even if the accessory is installed, the buckle installation through hole of the middle cover cannot be tightly blocked, and when the breaker is disconnected, part of gas and electric arc can be strung upwards from the reserved gap of the accessory buckle and cannot enter an arc extinguishing area in time.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a take circuit breaker of module.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a take circuit breaker of module, its includes base, well lid and upper cover, in cover and be equipped with the annex mounting groove, can dismantle in the annex mounting groove and be provided with the annex module rather than forming the shutoff, the upper end and the upper cover bottom contact of annex module set up, and by its up-and-down motion is restricted to the upper cover.

The accessory module includes a main body and a vent blocking body disposed on one side of the main body.

The main part is the box that cavity set up, be equipped with the strengthening rib of crisscross setting in the box, the strengthening rib extends the setting to the box outward.

The reinforcing ribs and the main body are integrally formed.

The air hole blocking body is matched with the fastening groove of the accessory mounting groove.

The air hole blocking body comprises two U-shaped structures formed by extending one side of the main body, two adjacent surfaces of the two U-shaped structures are sealed to form a first blocking surface, and the upper sides of the two first blocking surfaces are connected through a second blocking surface.

The utility model has the advantages that: through letting the upper cover with the annex module spacing in the annex mounting groove of well lid, saved the structure that adopts the buckle in the past, realized the complete shutoff to the annex mounting groove, like this can simply install, can be close to the buckle installation through-hole jam compactness of electric arc district with well lid again, gas and electric arc up cluster when preventing that the circuit breaker divides the branch, promote the arc extinguishing ability of circuit breaker.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the present application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., "fixed" may be fixedly connected or detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in the figure, the utility model provides a take circuit breaker of module, it includes base, well lid and upper cover, in cover and be equipped with the annex mounting groove, can dismantle in the annex mounting groove and be provided with the annex module 4 rather than forming the shutoff, and annex module upper end and upper cover bottom contact, and quilt its up-and-down motion is restricted to the upper cover. Accessory mounting groove is the same with current accessory mounting groove, and this application will need the fixed mode of buckle in the past through the structure of change accessory module, changes the upper cover restriction into fixedly to the fretwork design of buckle department has been saved, utilizes the mode of shutoff accessory mounting groove completely, and gas and electric arc up cluster when preventing the circuit breaker and divide absolutely.

The accessory module comprises a main body 41 and an air hole blocking body 42 arranged on one side of the main body, wherein the air hole blocking body is consistent with an original buckle structure, and the air hole blocking body completely blocks a buckle installation through hole of an accessory installation groove.

The main part is the box that cavity set up, be equipped with the strengthening rib of crisscross setting in the box, the strengthening rib extends the setting to the box outward. The reinforcing ribs 411 are integrally formed with the main body. Through the strengthening rib that extends the formation, be higher than well lid design for when upper cover and well lid are fixed, this strengthening rib can be supported by the upper cover bottom and press, thereby with this annex module restriction in the annex mounting groove.

The gas pocket blocking body includes two U type structures 421 that extend to form by main part one side, and two adjacent faces of two U type structures seal and form first fender face 422, and two first fender face upsides keep off the face 423 through the second and link to each other, utilize first fender face and second to keep off the U type structure shutoff that the face will originally hollow out the design to avoid the gas pocket in the buckle installation through-hole to expose, realized full shutoff effect.

The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of the present invention.
