[0002] The existing low-voltage molded case circuit breaker wiring installation adapter has the advantages of easy maintenance and replacement, simple installation and disassembly, saving cabinet space, and simple wiring. However, each phase has a pawl and a screw. Press the pawl tightly against the bus bar and the connecting plate, so there are the following disadvantages: it needs to be installed and disassembled from the inside of the cabinet; when the screws of each phase are connected, they are subjected to large tangential and radial forces; when installing, multiple screws need to be screwed

Embodiment Construction
[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0018] Such as Figure 1 to Figure 3 As shown, a busbar adapter for a molded case circuit breaker includes a housing, and the back side of the housing is provided with a three-phase busbar 1, a molded case circuit breaker 2, a connecting plate 4, a spring leaf 5 and a sliding Block 6, three adjustment devices 3 are arranged symmetrically at both ends of the front side, the three-phase busbar 1 and the molded case circuit breaker 2 are fixed together, and can move down to the spring in the same direction as the slider 6. In the piece 5, the size of the spring piece 5 is smaller than that of the three-phase bus bar 1, and the inner side near the center of the housing is provided with a connecting plate 4 matching it. The adjustment device 3 includes a rotating disk 31 with a handle and a The guide plate 32, the handle on the rotating ...

The invention discloses a busbar-type adaptor used for a molded case circuit breaker. The adaptor comprises a shell. A back side of the shell is provided with a three-phase bus, the molded case circuit breaker, a connection plate, a spring sheet and a slide block. Two ends of a front side are symmetrically provided with three adjusting apparatuses. The three-phase bus and the molded case circuit breaker are fixedly connected and can move downwardly and move into the spring sheet along a direction which is the same with a slide block motion direction. The size of the spring sheet is smaller than the size of the three-phase bus. An inner side, which is closes to a shell center, is provided with the connection plate which is cooperated with the inner side. Each adjusting apparatus comprises a rotation disc with a handle and a guide plate with a chute. The guide plate is fixedly connected to the slide block through a bolt. In the invention, a cam slide block structure is used to replace a pawl and a screw so that installation can be performed from a front side of a cabinet body; through a single operation, installation and fixation of an incoming line and a circuit breaker can be realized; and a layout of electric appliance components in a set of cabinet body is optimized and complicated wiring is reduced.
Description
technical field [0001] The invention relates to an accessory of a molded case circuit breaker, in particular to a bus bar adapter used for a molded case circuit breaker. Background technique [0002] The existing low-voltage molded case circuit breaker wiring installation adapter has the advantages of easy maintenance and replacement, simple installation and disassembly, saving cabinet space, and simple wiring. However, each phase has a pawl and a screw. The ratchet is tightly pressed against the bus bar and the connection plate, so there are the following disadvantages: it needs to be installed and disassembled from the inside of the cabinet; the installation screws of each phase are connected to withstand large tangential and radial forces; multiple screws need to be screwed during installation. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a busbar adapter for molded case circuit b...
