Detailed description of the invention

In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing By specific embodiment, the present invention is described in more detail.

Fig. 2 and Fig. 3 is schematic perspective view and the exploded view of bus tie 10 respectively.Such as Fig. 2 and 3 Shown in, bus tie 10 includes insulated sleeve 11 in a tubular form and is positioned in insulated sleeve 11 Contact tube 12.

As it is shown on figure 3, contact tube 12 is in a tubular form, its two ends are respectively provided with for clamping touching of bus 121,122.Contact 121 is the most identical with contact 122, only describes contact in detail at this 122.There are 1221,6 breach 1221 of 6 breach all along contact tube 12 on contact 122 Length direction extends.6 breach 1221 are preferably evenly distributed through on contact 122, thus by contact 122 are divided into 6 identical intermediate plates of shape.The lateral wall of contact 122 has the fingertip groove 1222 of annular. Bus tie 10 also includes the spring touch finger 13 being positioned in fingertip groove 1222, and spring touch finger 13 can Contact 13 is made to clamp bus more securely.Contact tube 12 is preferably by conductive material (such as resistance Little copper) one-body molded.

The lateral wall of insulated sleeve 11 has two annular flange flange 111 and medial wall and contact tube 12 Lateral wall suitable.Insulated sleeve 11 preferably employs the insulant of flexibility and makes, for example with Silicone rubber is one-body molded.

Bus tie 10 also includes the earth lead 14 being enclosed within insulated sleeve 11.Earth lead 14 is excellent Choosing uses flexible conductive material to make, thus realizes the lateral wall with insulated sleeve 11 and closely cooperate.

Fig. 4 is the section view that the insulated sleeve in the bus tie shown in Fig. 2 is cut open along its length Figure.As shown in Figure 4, the two ends of insulated sleeve 11 medial wall are respectively arranged with first annular locating part 112 and the second annular stop part 113.First annular locating part 112 and the second annular stop part 113 Between distance equal to the length of contact tube 12, therefore in contact tube 12 is positioned at insulated sleeve 11 Time, contact tube 12 is played spacing work by first annular locating part 112 and the second annular stop part 113 With.The medial wall of insulated sleeve 11 is coated with the internal shield 114 of conduction, and internal shield 114 can be all The electromagnetic field that even contact tube 12 produces in the energized state, avoids contact tube 12 to occur local to put simultaneously Electricity.The external shielding layer 115 of conduction it is coated with between two annular flange flange 111.Earth lead 14 preferably overlaps On external shielding layer 115 (shown in Figure 2), it is to avoid insulated sleeve 11 is put with ground connection housing Electricity is dangerous.

Below by the installation method of summary bus tie 10: first earth lead 14 is enclosed within insulated sleeve On 11, then spring touch finger 13 is bound round in fingertip groove 1222, finally contact tube 12 is inserted insulation In sleeve pipe 11 so that contact tube 12 is positioned at first annular locating part 112 and the second annular stop part 113 Between, it is achieved the installation of bus tie 10.Bus tie 10 part of the present invention is few, installs Convenient, do not result in assembling by mistake.The most less part also makes the volume of bus tie 10 subtract Little, cost reduces.

Fig. 5 is cuing open of cutting open along its length after the bus tie shown in Fig. 2 is arranged on insulating cylinder View.As it is shown in figure 5, bus tie 10 is positioned in the insulating cylinder 19 being made up of epoxy resin, Now two annular flange flange 111 are near direction bending each other, add bus tie 10 with Extraneous insulating properties, shield the electric field outside insulated sleeve 11.

As it is shown in figure 5, the external diameter of bus 17,18 is more than or is slightly larger than the internal diameter of contact 121,122, Bus 17,18 inserts in contact 121,122 respectively, and contact 121,122 can be the most outside Expansion, therefore clamps bus 17,18 in the case of not by external force or other clamping devices respectively, Realize the electrical connection of bus 17,18.

Spring touch finger 13 adds the chucking power of 121,122 pairs of buses 17,18 of contact, improves The reliability of bus electrical connection.In other examples, bus tie 10 can not also have Spring touch finger 13.

In other embodiments of the invention, the breach on contact can be more or less than 6.

Although the present invention has been described by means of preferred embodiments, but the present invention is not limited to Embodiment as described herein, the most also includes done various Change and change.
