Abstract
The sleeve for the fastener assembly has a sleeve body with cylindrical outer surface and the inside of the sleeve body is a cone which becomes thinner toward the end cap, and the inside of the end cap is one other cone which becomes thinner toward the end of the sleeve body far from the end cap. The present invention also relates to one fastener assembly including one sleeve and one screw bolt with a truncated cone head.
Description
The present invention relates to a kind of sleeve, this sleeve and a bolt form a fastener together, are used for an electric terminal is fixed on a for example railway line.
At US1748532, US2248845, multiple scheme has been proposed the electric terminal fastener among the GB214139, this fastener generally includes a sleeve that a taper body arranged, and this sleeve can be split, and also can not split, and end cap, be used for same bolt with a conical head and link to each other, when sleeve is arranged in one for example during the hole of a rail web, this bolt can pass this sleeve so that fastener is fixed in this hole.
A basic purpose of the present invention provides the composite set of a kind of sleeve that has improved and sleeve and bolt, forming a fastener.
According to a first aspect of the present invention, a sleeve is provided, this sleeve is an assembly of a fastener, this sleeve comprises a body, the outside face of this body is cylindrical and is provided with the end cap of an enlarged-diameter in the one end, the inside of this body is for away from its tapered cone in end cap one end-to-end lid place, and end cap inside be from away from the end of body to the tapered cone of body.
The invention provides a sleeve that bicone is arranged like this, end cap in-to-in cone rises and is housed in the metal that sleeve is packed into and is out of shape from end cap in the process in the hole.
In detail, it is inner cone about 8 ° that this sleeve can have a tapering, and this end cap a tapering also can be arranged is inner cone about 8 °.
This sleeve is preferably made of copper, and is preferably zinc-plated to strengthen electric connection.
A second aspect that has independent importance according to the present invention, a sleeve consistent with first aspect is provided, the same bolt combination of this sleeve, this bolt comprise that a screw rod that is suitable for passing this sleeve and end at screw rod are suitable for the conical head that matches with the interior cone of sleeve body.
Bolt is preferably made by 304 corrosion-resistant steels.
Bolt is preferably fastening by a nut, and nut preferably BZP steel is made, and preferably puts into a pad betwixt, and this pad preferably also is that the BZP steel is made.Nut is the nylon lock preferably, promptly is provided with a single-piece nylon locking piece.
In use, after for example holing on the rail web of an electric connecting point of needs insertion, the diameter in hole obviously should be close with the external diameter of sleeve body, and the length of body is about the thickness of rail web, sleeve will manually insert in the hole, up to the end cap of enlarged-diameter and web side near.Opposite side from the rail web inserts the screw rod of bolt by sleeve then, wherein places pad between nut and liner ring, with the cover upper nut.Cooperate more fasteningly between the clamp nut cone surface that can make bolt cap and the sleeve gradually, be housed in the annular space that the inner cone by the end cap of enlarged provides in the softer distortion of materials of fixation procedure middle sleeve.
In an exemplary fashion each side of the present invention is described in detail below with reference to the accompanying drawings.
Fig. 1 is the lateral plan of a sleeve according to a first aspect of the invention.
Fig. 2 is the lateral plan that is used for making up with sleeve a bolt forming a fastener according to second aspect present invention.
Fig. 3 is a lateral plan that is used to be screwed in the nut on the screw rod.
Fig. 4 is a lateral plan that is located at pad wherein.
In the drawings, sleeve 1 comprises a body 2, and this body 2 has a columniform outside face 3 and the end cap 4 of the enlarged-diameter of an one is arranged at an end of outside face 3.It is 8 ° female cone 5 that sleeve 2 has a cone angle, and the surface 7 of this circular cone from the end 6 of circular cone to end cap 4 is tapered.Equally, it is 8 ° female cone 8 that end cap 4 has a cone angle, and it is tapered to its surface 7 from its end 9 away from body 2, and these two tapers are line of centers with line 10 all.As shown in Figure 2, a bolt 11 comprises a screw rod 12, at an end of bar a conical head 13 is arranged.
When using as a fastener, bore a hole 14 by rail web 15, the length of body 2 is about the thickness of web 15, and the outside face 3 of body is corresponding to the diameter in hole 14.When the complete patchhole 14 of sleeve 1, as shown in Figure 1, on the surface that the face 7 of end cap 4 just adjoins with it near web 15.From the another side of rail web screw rod 12 is passed from taper hole 5 and 8,, as shown in Figure 4, and then will have the nut 17 of a nylon locking piece 18 to be added on the screw rod 12 so that may at first add upper gasket 16 at screw rod 12.Swivel nut 17 closely cooperates with hole 14 fully up to sleeve 1 especially outside face 3 gradually, because the conical head 13 of bolt 11 is fastening, makes sleeve 1 distortion made of copper.
