The protecting sleeve for the busbar is characterized in that the protecting sleeve seat, the protecting sleeve cover and the flexible quick-plug connecting piece can be of the same color, such as blue, yellow, red and the like, so that protecting sleeves with different colors are arranged at two ends of the busbar and used for distinguishing the polarity of connecting electrodes at two ends of the busbar.

A female protective sheath of arranging, its female row inserts the entry and has two, the symmetry sets up lateral wall about the sheath seat for female swift running-through of arranging inserts.

The invention has the following beneficial effects:

1, the volume of the protection measures for the connection part of the busbar bolt is greatly reduced.

And 2, the protection effect of the connecting part of the bus bolt is improved.

3, the sheath base and the sheath cover use a threaded connection structure, so that the reliability is improved.

And 4, a measuring lead outlet is arranged, so that the function of a measuring lead is increased.

And 5, the sheath cover and the sheath base are connected into an integrated structural member through the flexible quick-insertion connecting piece, and the sheath cover, the sheath base and the flexible quick-insertion connecting piece are separately manufactured, so that the manufacturing manufacturability is improved.

6, the sheath base and the sheath cover are both made of hard plastic ABS, so that the appearance is attractive, the strength and the rigidity are sufficient, and the assembly and the disassembly are convenient; the quick-insertion connecting piece is made of soft plastic and is flexible in movement.

And 7, the busbar connection protective sleeve adopts different colors to distinguish different connectors.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the invention discloses a busbar protective sleeve, which comprises a sheath base 1, a sheath cover 2 and a flexible quick-plug connector 3 for connecting the sheath base 1 and the sheath cover 2, wherein the sheath base 1 and the sheath cover 2 are connected through the flexible quick-plug connector 3 to form an integrally designed busbar connecting protective sleeve. The utility model discloses a flexible quick plug connector, including sheath seat 1, sheath cover 2, lateral wall of sheath seat 1 are equipped with square female jack 1.1 of arranging for insert female arranging 5.1, the section view after the female arranging 5.1 of installation is shown in fig. 4. Positive upper portion of sheath base 1 is provided with measures the lead wire and inserts mouth 1.3 for insert and measure the lead wire, the bottom of sheath base 1 is provided with a circular shape electrode installation mouth 1.2, sheath lid 2 through threaded connection at the top opening part of sheath base 1, form a cavity with sheath base 1 for it connects with bolt and external connector of measuring the lead wire to hold female arranging 5.1.

As a first embodiment of the present invention, the structure diagrams of one busbar insertion opening 1.1 and the quick insertion opening respectively arranged on the left and right sides of the sheath base 1 and the busbar 5.1 after being installed are shown in fig. 5 and 6.

As a second embodiment of the present invention, there are two busbar insertion ports 1.1 symmetrically disposed on the left and right side walls of the sheath seat 1, and a through hole 7.1 is formed between the two busbar insertion ports 1.1 and the chamber for the quick penetration and insertion of the busbar 5.1. The second technical scheme adopted by the invention for solving the technical problems is that on the basis of the first technical scheme of the invention, in order to meet the requirement of a busbar penetrating structure connected by using bolts in the middle of a busbar 5.1 and form effective protection, as a left busbar inserting hole 1.1 and a right busbar inserting hole 1.1 which are relatively penetrated are arranged on a sheath base 1, the busbar can penetrate through a protective sleeve, the protective sleeve 1 is positioned in the middle position of the busbar 5.1, the detailed structure is shown in the attached drawings 7 and 8, the structure is suitable for busbars needing to be connected by using bolts in the middle position of the busbar or needing a plurality of bolts, and the specific application structure is shown in the attached drawings 9 and 10.
