Description

Rotary bus connector protective cover

Technical Field

The utility model relates to the technical field of bus connectors, in particular to a rotary bus connector protection cover.

Background

In modern economic production and daily life, the power consumption of various industries is increased rapidly, and especially in the appearance of numerous high-rise buildings and large-scale factory workshops, the traditional cable serving as a power transmission wire cannot meet the requirements in a large-current transmission system.

With the vigorous development of society, the plug-in type bus duct is more and more emphasized as a power transmission conductor, the unique characteristics (such as small occupied space and high reliability in large-capacity transmission) of the plug-in type bus duct are more and more prominent, and a plurality of large buildings (especially super large-size, ultrahigh and super-scale buildings) basically cannot be lack of the plug-in type bus duct.

In the plug-in bus duct product series, a "bus connector" is an important component accessory and is absolutely indispensable, and the whole plug-in bus duct system is absent without the "bus connector".

The plug-in type bus duct is formed by connecting bus ducts one by one in a relay mode through a special bus connector, and because the bus ducts cannot be directly connected with each other due to the influences of transportation, production process, equipment adaptability and other factors, the bus ducts must be connected through additional parts (namely the bus connector).

However, a general bus bar connector can only perform linear connection, that is, two sections of bus bars to be connected can only enter from two ends of the bus bar connector in parallel and opposite directions respectively, and then are clamped by a specially-matched bolt of the bus bar connector.

For example, patent document CN112751300A entitled "a bus bar connector and bus duct" discloses a bus bar connector, which includes at least two insulating blocks, a screw rod and a nut, wherein the at least two insulating blocks are mounted on the screw rod, the nut is mounted on the screw rod, and the nut rotates relative to the screw rod to press the two insulating blocks against each other, so that the two conductive bars between the two insulating blocks are electrically connected. The bus bar connector only supports a connection mode that two ends of the bus bar connector are inserted into the bus bar groove in parallel and opposite directions.

In the long-term use process, the single connection method can not meet the market demand for a long time, because each standard section of the bus duct is fixed, if turning or changing the direction and the like are needed, additional accessories are required to be installed, and the accessories are right-angled bends which are shaped in a standard mode, so that the bus duct is not flexible and inconvenient, and the installation and the use of the plug-in type bus duct are seriously hindered if the bus duct is turned at a special angle.

In view of this, the applicant designs a rotary bus connector with two ends of the connector capable of rotating at will, as shown in fig. 1, including a first connecting piece 71 and a second connecting piece 72 attached to each other, where the first connecting piece 71 and the second connecting piece 72 are both provided with a butt end 9 and a rotating end 10, a rotating hole 11 is opened in the middle of the rotating end 10, a rotating shaft penetrates through the rotating hole 11, and isolation washers 8 are connected in series to the rotating shaft corresponding to the left and right ends of the first connecting piece 71 and the second connecting piece 72 attached to each other.

However, after the butt joint of the bus connector is completed, in order to improve the protection capability of the bus connector, a protection cover needs to be installed on the outer side of the bus connector, but a general bendable material is soft in texture and cannot absorb impact force, so that a protection structure aiming at the characteristic that the rotary bus connector can be bent at will is lacked in the market at present, and the construction and installation convenience of the rotary bus connector is influenced.
