Description
Technical Field
The utility model belongs to the technical field of electrical equipment, especially, relate to a miniature circuit breaker convenient to firm installation.
Background
A miniature circuit breaker is a mechanical switch appliance which can connect, bear and break the current under normal circuit condition, and also can connect, bear and break the current for a certain time under the specified abnormal circuit condition, and mainly comprises an operating mechanism, contacts, a protection device (various releases), an arc extinguishing system and the like. Among the prior art, miniature circuit breaker's the left and right sides all is flat, can closely arrange a plurality of miniature circuit breaker and install on a slide rail, nevertheless because through the dovetail cooperation between miniature circuit breaker and the slide rail, the installation of being convenient for generally still adopts mobilizable formula design with the dovetail, leads to fit clearance between miniature circuit breaker and the slide rail great, and a plurality of miniature circuit breaker who arrange together can't form firm whole, and the installation steadiness is relatively poor.
SUMMERY OF THE UTILITY MODEL
To the defect among the prior art, the utility model provides a miniature circuit breaker convenient to firm installation can consolidate through the middle piece between two adjacent miniature circuit breakers, can transversely advance mutual location along the slide rail, and a plurality of miniature circuit breakers are arranged and are installed wholeness after on the slide rail better, make miniature circuit breaker form the restraint each other, improve the steadiness of integral erection.
The utility model discloses a miniature circuit breaker convenient to stabilize installation, including circuit breaker body and middle piece; the left side and the right side of the circuit breaker body are symmetrically provided with two slotted holes, the cross sections of the middle block and the slotted holes are the same in shape, and the depth of each slotted hole is smaller than the length of the middle block; reinforce through the middle piece between two adjacent miniature circuit breakers, can transversely fix a position each other along the slide rail.
Further, the cross section of slotted hole and middle piece is circular, and the slotted hole that is located the right side is equipped with the internal thread, and the left end of middle piece is equipped with the external screw thread with the internal thread assorted of slotted hole, can pass through screw thread fixed mounting with the middle piece on corresponding miniature circuit breaker, during the installation with another miniature circuit breaker paste tightly and with the right-hand member block of middle piece can, convenient operation.
Furthermore, the depth of the slotted hole is not less than half of the length of the middle block, so that the plurality of miniature circuit breakers can be tightly attached.
Furthermore, an annular boss is arranged in the middle of the middle block; the mouth of slotted hole is followed the department and is equipped with annular heavy groove corresponding annular boss, guarantees that the middle piece is in between two adjacent miniature circuit breakers.
Furthermore, a radial through hole is formed in the right end of the middle block, and a screwdriver can be inserted into the through hole to screw and disassemble the middle block.
The utility model has the advantages that: the utility model discloses a miniature circuit breaker convenient to stabilize installation, including circuit breaker body and middle piece; the left side and the right side of the circuit breaker body are symmetrically provided with two slotted holes, the cross sections of the middle block and the slotted holes are the same in shape, and the depth of each slotted hole is smaller than the length of the middle block; reinforce through the middle piece between two adjacent miniature circuit breakers, can transversely fix a position each other along the slide rail.
