Description

Busbar assembly and floating connector

This case relates to a power conducting component, particularly a busbar assembly with a floating connector.

Generally speaking, bus assemblies are often used in cabinet buses, which are structured to electrically connect the output electrodes of one or more power supply units to the cabinet bus, so that the power output by one or more power supply units is distributed to electronic devices through the cabinet bus of the server cabinet, thereby supplying power to the electronic devices.

FIG. 1 is a three-dimensional schematic diagram of a known bus assembly locked to a cabinet bus, and FIG. 2 is a cross-sectional structural schematic diagram of the known bus assembly shown in FIG. 1 locked to a cabinet bus. As shown in FIG. 1 and FIG. 2, the known bus assembly 900 includes two output terminals 901, and a distance 902 is provided between the two output terminals 901. The two output terminals 901 of the bus assembly 900 are locked with a plurality of bolts 903 and electrically connected to two connection terminals 905 of a cabinet bus 904 to realize power transmission between the bus assembly 900 and the cabinet bus 904. However, the distance 902 between the two output terminals 901 needs to be adjusted according to the two connection terminals 905 of the cabinet bus 904. When the distance 902 is too small, the bolts 903 may not be able to be locked and assembled. When the distance 902 is too large, the output terminals 901 of the bus assembly 900 will generate great stress, which may cause the risk of device damage.

On the other hand, the two output ends 901 of the conventional bus assembly 900 and the two connection ends 905 of the cabinet bus 904 are respectively provided with a plurality of through holes (not shown) for a plurality of bolts 903 to pass through and be locked therein. However, the plurality of through holes are prone to tolerances, and when the tolerances are too large, the bolts 903 may not be locked and assembled. In addition, the bolts 903 are usually assembled manually, and during the manual assembly process, the bolts 903 may be skewed, which may cause the bolts 903 to be stuck in the through holes and unable to be removed.

In view of this, it is necessary to develop a busbar assembly and a floating connector thereof to solve the problems faced by the prior art.

The purpose of this case is to provide a busbar assembly and a floating connector thereof, which can achieve the effects of switching the connection direction with the cabinet busbar, reducing the stress between devices and reducing manual assembly errors.

The first output end of the first connection bus can be slidably blindly plugged into the bus end connection seat of at least one first connection module. The second output end of the second connection bus can be slidably blindly plugged into the bus end connection seat of at least one second connection module. The cabinet end connection seat frame is provided for the corresponding connection ends of the two connection ends of the cabinet bus to be slidably blindly plugged therein.

To achieve the above-mentioned purpose, another general implementation of the present invention is to provide a floating connector, which is configured to transmit the power received by the bus group to the cabinet bus. The bus group includes at least one connecting bus. At least one connecting bus includes an output end. The cabinet bus includes at least one connecting end, wherein the floating connector includes at least one connecting module.

The two conductive plates 44 respectively include a first end 44a and a second end 44b. The two first ends 44a of the two conductive plates 44 are arranged corresponding to the bus end opening 432 to form a bus end connection seat 4a. The two second ends 44b of the two conductive sheets 44 are arranged corresponding to the cabinet end openings 433 to form a cabinet end connection seat 4b. When the first output terminal 1b of the first connection bus 1 is blindly plugged into the bus end connection seat 4a of the first connection module 41, the first output terminal 1b is sandwiched between the two first ends 44a of the two conductive sheets 44 and can slide along the first direction X, while achieving electrical connection between the conductive sheet 44 and the first output terminal 1b. When the second output terminal 2b of the second connection bus 2 is blindly plugged into the bus end connection seat 4a of the second connection module 42, the second output terminal 2b is sandwiched between the two first ends 44a of the two conductive sheets 44, and can slide along the first direction X, while realizing the electrical connection between the conductive sheets 44 and the second output terminal 2b.

Each protrusion 441 is formed by a conductive piece 44 protruding in the direction of the other conductive piece 44. When the first output terminal 1b of the first connection bus 1 is blindly inserted into the bus terminal connection seat 4a of the first connection module 41 (as shown in FIG. 9), the protrusion 441 of the first end 44a of the two conductive pieces 44 of the first connection module 41 abuts against the first output terminal 1b, so that the first output terminal 1b is sandwiched and contacts between the two protrusions 441 of the first connection module 41. When the second output terminal 2b of the second connecting bus 2 is blindly inserted into the bus terminal connector 4a of the second connecting module 42 (as shown in FIG. 9 ), the protrusion 441 of the first end 44a of the two conductive plates 44 of the second connecting module 42 abuts against the second output terminal 2b, so that the second output terminal 2b is sandwiched and contacts between the two protrusions 441 of the second connecting module 42. When the two connection ends 51 of the cabinet bus 5 are blindly inserted into the cabinet end connection seats 4b of the first connection module 41 and the second connection module 42 respectively (as shown in FIG. 9 ), the protrusions 441 of the second ends 44b of the two conductive pieces 44 of the first connection module 41 and the second connection module 42 respectively abut against the two connection ends 51 of the cabinet bus 5, so that the two connection ends 51 of the cabinet bus 5 are respectively sandwiched and contacted between the two protrusions 441 of the second ends 44b of the two conductive pieces 44 of the corresponding first connection module 41 and the second connection module 42. The first output terminal 1b, the second output terminal 2b and the two connection terminals 51 of the cabinet bus 5 are clamped by the protrusion 441 of the conductive sheet 44 to reduce the risk of the first output terminal 1b, the second output terminal 2b and the cabinet bus 5 falling off from the bus terminal connection base 4a and the cabinet terminal connection base 4b.

By setting the limiting element of the floating connector, the first limiting hole and the second limiting hole of the connecting bus, the sliding distance of the connecting bus is limited, thereby reducing the risk of the connecting bus falling off or poor contact.
