The present invention directly installs the connecting terminal on the bus bar with screws through the connecting terminal protruding from the shell, so that the connecting terminal and the bus bar are closely attached, so that the electrical connection performance between the adapter and the bus bar is stable and reliable, and can avoid the adverse operating environment on board. adverse effects.

Description

A marine busbar circuit breaker adapter

technical field

The invention relates to a marine busbar type circuit breaker adapter, which belongs to the technical field of low-voltage electrical appliances.

Background technique

The existing marine molded case circuit breaker is generally fixed on the mounting plate in the switchboard with screws, and then the circuit breaker and the busbar are connected together through the bus bar to realize the electrical connection. At this time, the busbar and the molded case circuit breaker need to be measured first The distance between the devices determines the shape and size of the busbar.

The existing circuit breaker installation method has the following disadvantages: the volume of the switchboard is increased, the cost is high, the operation is complicated, and the use is inconvenient. In addition, due to the influence of inclination, swaying, vibration and shock when used on board, the common busbar structure hung by hooks cannot meet the requirements of the marine environment.

Contents of the invention

The technical problem to be solved by the present invention is to provide a marine bus-type circuit breaker adapter that occupies the smallest space, has a compact structure and is reasonably wired.

In order to solve the above technical problems, the technical solution of the present invention is to provide a marine bus-type circuit breaker adapter, including a housing, the first terminal block, the second terminal block, the third terminal block and three fourth terminal blocks are respectively arranged on At the six ports of the casing, sockets are respectively arranged above the first wire base, the second wire base, the third wire base and the three fourth wire bases, and the sockets are connected with the first wire base, the second wire base, the third wire base The connection between the terminal block and the fourth terminal block is closely connected, and it is characterized in that: there is a soft connection between the first terminal block, the second terminal block and the third terminal block and their corresponding terminals, and the two ends of the soft connection are respectively connected to the The first terminal block, the second terminal block, the third terminal block are closely connected with the corresponding terminals, and there are three transverse grooves at the bottom of the shell, and the bus bar is inserted into the transverse grooves, and a Rectangular holes, the three terminals protrude from their respective rectangular holes relying on the flexibility of the soft connection.

Preferably, the tight connection between the socket and the first wire base, the second wire base, the third wire base and the fourth wire base is realized by welding.

Preferably, a connecting hole is opened on each of the connecting terminals for connecting with the bus bar through screws.

The present invention provides a marine busbar type circuit breaker adapter, the device can be directly fixed on the mounting plate, the busbar is stuck in the transverse groove at the bottom of the device, and the terminal is connected to the busbar through screws, so that its electrical connection performance is stable and reliable. At the same time, it can avoid the adverse effects caused by the harsh environment such as shock and vibration on board.

detailed description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

As shown in Figure 1, it is a structural schematic diagram of a marine bus-type circuit breaker adapter provided by the present invention. The marine bus-type circuit breaker adapter includes a housing 1, a first terminal block 2, a second terminal block 3, a third The wire socket 4 and the three fourth wire sockets 6 , and the six wire sockets are respectively installed on the six ports of the housing 1 through screws 5 .

2 and 3 , the sockets 10 are respectively arranged above the first terminal block 2 , the second terminal block 3 , the third terminal block 4 and the fourth terminal block 6 , and are tightly connected to each terminal block by welding. When in use, the circuit breaker is directly inserted into the socket 10 to realize the electrical connection with the adapter. There is a soft connection 12 between the first terminal block 2, the second terminal block 3 and the third terminal block 4 and their corresponding terminals 9, and the two ends of the soft connection 12 are respectively connected to the terminal block and the rivet 11 by welding and riveting. The terminals are tightly connected. The bottom of the housing 1 is provided with three transverse slots, the bus bar 8 is inserted into the slots, and each transverse slot is provided with a rectangular hole, and the three connecting terminals 9 protrude from the rectangular holes at the bottom of the housing 1 by virtue of the flexibility of the soft connection 12. At the same time, the connecting terminal 9 is directly fixed on the bus bar 8 with the screw 7, so that it is closely attached to the bus bar 8, so as to realize the fixing and electrical connection between the adapter and the bus bar.

Although the present invention has been described with reference to the above-mentioned embodiments, those of ordinary skill in the art should realize that the above-mentioned embodiments are only used to illustrate the present invention, and it should be understood that various changes and modifications can be made in a broad sense. There is no departure from the present invention, so it is not intended as a limitation to the present invention. As long as it is within the spirit of the present invention, changes and deformations to the above-mentioned embodiments will fall within the protection scope of the claims of the present invention.
