Description

Technical Field

[0001] The invention relates to the technical field of electric tools, and in particular to a bolt connection method. Background Art

[0002] The bolt wiring method is a method for fixing and conductively connecting an external wire to a wiring bolt, and generally includes a locking mechanism for fixing the connection wiring bolt and a wiring mechanism for fixing the connection wire. In traditional wiring devices, the locking mechanism generally relies on a single threaded connection, which is prone to loosening after repeated use. In addition, the distance between multiple bolts is short, leaving little space for the wiring device to rotate, which makes the bolt wiring device extremely inconvenient to load and unload. The wiring mechanism ends of traditional wiring devices are directly pressed onto the wires by bolts, which can easily cause wire breakage, and the resistance of the damaged wires will also increase, causing local heating, which may seriously cause power accidents. Summary of the invention

[0004] Preferably, when the slider continues to slide into the annular groove, the conical tightening hole completely squeezes the elastic connecting piece, and at this time, the bolt wiring device body is rotated to rotate the slider in the annular groove.

[0005] Preferably, a plurality of circular grooves are evenly arranged at the bottom of the annular groove along the circumferential direction, a column groove is arranged at the top of the slider, a spring is arranged at the bottom of the column groove, and a ball is arranged at the top of the spring, and the ball can slide into and out of the circular groove.

[0009] Preferably, the fastening bolt is inserted into the wiring hole and then pressed onto the gasket.

[0010] Preferably, the inner diameter of the wiring hole increases from the outside to the inside, thereby effectively preventing the wire from loosening and being pulled out of the wiring hole.

[0011] Preferably, the inner wall of the gasket is provided with ridges embedded in the wire to increase friction.

[0012] Compared with the prior art, the bolt connection method of the present invention has the following beneficial effects: First, connect the thread of the tapered connecting sleeve to the terminal bolt, and then through the cooperation of the metal tapered connecting tube and the tightening hole, squeeze the three elastic connecting pieces of the tapered crimping tube inward through the tightening hole to hold the bolt terminal stud, so that the tapered crimping tube and the terminal bolt are in a locked state, the connection is firm, and the force is evenly distributed.

[0013] The conical connecting sleeve is an integrated structure, which has better overall structural strength and reduces parts.

[0014] A slider is provided on the side wall of the tapered connecting sleeve, which cooperates with the slideway on the side wall of the tightening hole and slides to the bottom ring groove.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0021] A bolt connection method, using a bolt connection device, the bolt connection device is as follows Figure 1-4As shown, it includes a bolt wiring device body 1, which includes a locking mechanism 2 and a wiring mechanism 5. The locking mechanism 2 includes a tapered connecting sleeve 3, a tapered tightening hole 8, a slideway 10 and an annular groove 11. The metal tapered connecting sleeve 3 is coaxially built into the tapered tightening hole 8. A through hole is opened at the bottom of the tapered tightening hole 8. The tapered connecting sleeve 3 is an integrated tapered sleeve, and its upper part is composed of a plurality of elastic connecting pieces 13. There are gaps between the plurality of elastic connecting pieces 13. The taper of the upper part of the tapered connecting sleeve 3 is greater than the tapered tightening hole 8; a threaded hole is opened inside the tapered connecting sleeve 3, and the same thread is also arranged inside the plurality of elastic connecting pieces; two sliders are opened on the side wall of the tapered connecting sleeve 3, and the sliders are consistent in size with the slideway 10 and the annular groove 11. When the slider moves downward through the slideway 10, the tapered tightening hole 8 will gradually squeeze the plurality of elastic connecting pieces 13 of the tapered connecting sleeve 3, and the gaps 14 between the plurality of elastic connecting pieces will gradually decrease to clamp the wiring bolt. When the slider continues to slide into the annular groove 11, the conical tightening hole 8 completely squeezes the elastic connecting piece. At this time, the bolt terminal device body 1 is rotated to make the slider rotate in the annular groove 11, which increases the connection stability and can change the direction of the bolt terminal device body 1. The bottom of the annular groove 11 is evenly provided with multiple circular grooves along the circumference, the top of the slider is provided with a column groove, the bottom of the column groove is provided with a spring, and the top of the spring is provided with a ball, which can slide in and out of the circular groove, thereby stabilizing the direction of the bolt terminal device body 1.

[0022] The wiring mechanism 5 includes three fastening bolts 4, a gasket 6 and a wire hole 7. The inner diameter of the wire hole 7 decreases from left to right, so that the wire inserted into the wire hole 7 can fully expand, and the outer wall just above the wire hole 7 is provided with three threaded holes with gradually decreasing diameters from left to right. The diameters of the three fastening bolts 4 decrease in sequence and are matched with the three threaded holes in sequence. A gasket 7 is provided on the upper inner wall of the wire hole 7. After the three fastening bolts are inserted into the wire hole 7, they are pressed against the three strip grooves 15 of different sizes of the gasket 7 in sequence, so that the gasket 7 can fully contact with the wire. The inner wall of the gasket 7 is provided with three convex ridges 16, and the sizes of the three convex ridges 16 gradually increase from right to left; after the fastening bolts press against the strip grooves 15, the three convex ridges 16 will fully contact with the wire and squeeze the wire to the inner wall of the wire hole, while reducing the contact resistance and the damage of the bolt to the wire.

[0023] As a preferred solution, in order to prevent the three strip grooves 15 of the gasket 7 from being unable to fully contact the fastening screws due to the insertion of the wire, one of the three fastening bolts can be first clamped with the corresponding strip groove 15, and then the wire can be inserted, and finally the remaining bolts can be contacted with the corresponding strip grooves.

[0024] During installation: first, insert the side wall slider of the tapered connecting sleeve 3 into the two slideways on the inner wall of the tapered tightening hole 8, then connect the terminal bolt with the threaded hole, rotate the bolt terminal device body to gradually thread the terminal bolt with the threaded hole, during this process, the tapered connecting sleeve gradually slides downward along the slideway until the slider is located in the annular groove, at which time the elastic connecting piece is completely squeezed by the tapered tightening hole; then, the direction of the bolt terminal device body is adjusted by rotating the bolt terminal device body to make the slider slide in the annular groove.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification or equivalent replacement of the present invention to obtain other implementation modes and drawings without any creative work shall fall within the protection scope of the present invention.
