Description
Technical field
The invention patent relates to connector technical fields, and specifically the equal return cable connection rivet formula of stray electrical current is swollen
Nail.
Background technique
In the existing swollen application followed closely in railroad track for power transformation, since the traveling of train shakes, usually make swollen nail pine
Dynamic to fall off, loose or dislocation will lead to the variation of resistance in railway voltage balancing procedure, and the variation of resistance can make electric voltage equalization efficiency
It reduces, so that adverse effect is caused to train apparatus, and existing swollen nail needs worker's running check to safeguard, maintenance cost
Height, it is time-consuming and laborious.
Summary of the invention
For various deficiencies existing in the prior art, the object of the present invention is to provide the equal return cable connections of stray electrical current
Rivet type is swollen nail, can be with the problems in effective solution background technique.
The equal swollen nail of return cable connection rivet formula of stray electrical current of the invention, including expansion set, screw rod, steel bowl formula spring pad
Circle, gasket and nut；The expansion set superficial expansion is simultaneously pressed on rail hole wall；The steel bowl formula spring washer is set to screw rod
Between head end and rail, and through screw-pressing on rail；The gasket is set to the tail end of screw rod, and is connected admittedly with nut
It is fixed.Screw rod and nut are all made of the stainless steel of 304 or more material.
Preferably, the swollen nail of the equal return cable connection rivet formula of the stray electrical current further includes connection terminal；The connecting pin
Son is set between screw rod tail end expansion set end face and gasket, is used for connecting wire.
Preferably, the expansion set both ends are designed with the protrusion for fixing position.
Preferably, the pitch face inclination angle of the steel bowl formula spring washer is greater than screw flight lift angle, for locking.
Preferably, it is equipped with connector lug below the connection terminal, is used for connecting wire.
Beneficial effects of the present invention:
By the steel bowl formula spring washer being arranged between screw rod head end and rail, so that swollen nail possesses good anti-loosing effect,
Stabilize electrical contact performance excellent between conducting wire and rail.
It is adaptable, be protected from weather influences, under room temperature can simple realization operation installation, be suitable for the condition of various environment
Under use and install, it is round-the-clock at any time construction, it can be achieved that high construction efficiency rate, high finished product rate, zero fraction defective.
Maintenance is simple, such as encounters situations such as conducting wire is surprisingly damaged, only needing to change conducting wire and stop nut can be completed, effectively
Avoid other connection types when rail may be replaced by having, because of the puzzlement caused by cable length deficiency.
Safe and reliable rivet formula expanded joint mode can effectively extend inspection and maintenance period.
Detailed description of the invention
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In attached drawing, each element or part are not
Centainly drawn according to actual ratio.
Fig. 1 is configuration schematic diagram of the invention；
Fig. 2 is mounting structure schematic diagram of the invention.
Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
It is as depicted in figs. 1 and 2: the equal swollen nail of return cable connection rivet formula of the stray electrical current of the present embodiment, including expansion set 1,
Screw rod 2, steel bowl formula spring washer 3, gasket 4 and nut 5；1 superficial expansion of expansion set is simultaneously pressed on rail hole wall；The steel
Bowl formula spring washer 3 is set between the head end and rail of screw rod 2, and is pressed on rail by screw rod 2；The gasket 4 is set to
The tail end of screw rod 2, and be connected and fixed with nut 5.Screw rod 2 and nut 5 are all made of the stainless steel of 304 or more material.
As a specific embodiment, the swollen nail of the equal return cable connection rivet formula of stray electrical current further includes connection
Terminal 6；The connection terminal 6 is set between 2 tail end expansion set of screw rod, 1 end face and gasket 4, is used for connecting wire.
As a specific embodiment, 1 both ends of expansion set are designed with the protrusion for fixing position.
As a specific embodiment, the pitch face inclination angle of the steel bowl formula spring washer 3 is greater than the screw thread of screw rod 2
Lift angle, for locking.
As a specific embodiment, it is equipped with connector lug 61 below the connection terminal 6, is used for connecting wire.
Working principle:
It is applied on screw rod 2 by the constant force that hydraulic tool provides, is allowed to move along direction of pull, 1 superficial expansion of expansion set is simultaneously
Press on rail hole wall, is buckled up to form full surface crimping with rail back side anchor；Due to tensions constant, so crimp force
Also constant, i.e., contact resistance is definite value；Connection terminal 6 is attached with 1 end face nut 5 of expansion set, and pressing force is pulled by torque
Hand control, to realize comprehensive quantization of contact resistance.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
