It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1-2, an embodiment of the present invention discloses a cable connector with a length adjustment function, which can be applied to an electrical power system, wherein during an installation process, one end of the cable connector can be connected to a cable, and the other end of the cable connector can be connected to a cable or an electrical power device. The cable connector disclosed in the embodiment of the present invention includes a bracket 100, a first connecting portion 200, a first elastic portion 300, and an electrical connection wire 400.
The bracket 100 can provide mounting locations for other components of the cable connector, and optionally the bracket 100 can be a frame-like structure so that other components of the cable connector can be mounted at various locations of the bracket 100.
In the embodiment of the present invention, the first through hole 110 is formed at the first end of the bracket 100, the first connecting portion 200 includes a first limiting end 210 and a first main body portion 220, the first limiting end 210 is connected to the first end of the first main body portion 220, and the first limiting end 210 can be in limiting fit with an outer side port of the first through hole 110 to prevent the first limiting end 210 from passing through the first through hole 110; the second end of the first main body 220 passes through the first through hole 110 and is in sliding fit with the first through hole 110.
The first elastic portion 300 is sleeved on the first main body portion 220, a first end of the first elastic portion 300 is elastically connected to an inner port of the first through hole 110, and a second end of the first elastic portion 300 is connected to a second end of the first main body portion 220. Referring to fig. 1, in this case, the first elastic portion 300 can not only prevent the second end of the first main body portion 220 from sliding out of the bracket 100 through the first through hole 110, but also the first elastic portion 300 can apply an elastic force to the second end of the first main body portion 220.
In a specific operation process, the first limit end 210 of the first connection portion 200 may be connected to a cable, and the second end of the bracket 100 may be connected to a cable or an electric device, in which case, the cable may generate a pulling force on the first limit end 210, and when the pulling force of the cable on the first limit portion 210 is increased, the second end of the first main body portion 220 overcomes the elastic force of the first elastic portion 300, so that the second end of the first main body portion 220 moves in a direction toward the first end of the bracket 100; when the pulling force of the cable on the first position-limiting part 210 is reduced, the second end of the first main body part 220 is under the elastic force of the first elastic part 300, so that the second end of the first main body part 220 moves in the direction toward the second end of the bracket 100.
The electrical connection wire 400 serves to electrically connect a cable at the first position-limiting end 210 with a cable or power equipment at the second end of the bracket 100, and specifically, the first end of the electrical connection wire 400 is connected with the first position-limiting end 210, and the second end of the electrical connection wire 400 is connected with the second end of the bracket 100.
As can be seen from the above, in the cable connector with a length adjustment function disclosed in the embodiment of the present invention, when the cable connector is applied to a power system, in a process that the sag of the cable increases, the pulling force of the cable on the first connection portion 200 decreases, in this case, the elastic force of the first elastic portion 300 can pull the second end of the first main body portion 220 to move in a direction toward the second end of the bracket 100, so as to decrease the sag of the cable, and further ensure that the ground safety distance of the cable meets the requirement; in the process of reducing the cable sag, the pulling force of the cable on the first connection portion 200 is increased, and in this case, the pulling force of the cable overcomes the elastic force of the first elastic portion 300, so that the second end of the first main body portion 220 moves in the direction toward the first end of the bracket 100, and the cable sag is increased, and then the pulling force of the cable is reduced, so as to prevent the cable connector or the power equipment from being damaged due to the excessive pulling force of the cable.
In an alternative embodiment of the present invention, the first elastic part 300 may be a coil spring. The spiral spring has the characteristics of simple and compact structure, so that the assembly is convenient, and meanwhile, the spiral spring has good impact absorption capacity and more precise adjusting capacity, so that the length of the cable can be conveniently adjusted. Of course, in order to make the connection of the coil spring more stable.
Based on this, in a specific assembling process, the coil springs with different stiffness coefficients can be selected according to the magnitude of the pulling force that the cable connector can withstand, so that the elastic force generated by the coil springs can more effectively adjust the length of the cable. Of course, the first elastic portion 300 may be other kinds of elastic structures, and is not limited to a coil spring.

Of course, in an alternative solution, the cable connector may further include a nut 500, the nut 500 may be threadedly engaged with the first main body portion 220, and the second end of the first elastic portion 300 may abut against an end surface of the nut 500 facing the first through hole 110. In this case, the second end of the first elastic part 300 is detachably connected to the first body part 220, thereby facilitating the installation and removal of the first elastic part 300; meanwhile, in the installation process, the extension range of the first elastic part 300 can be adjusted by rotating the nut 500, so that the length of the cable can be more effectively adjusted by the elastic force generated by the first elastic part 300.
Further, the cable automatic regulator may further include a first gasket 610, the first gasket 610 may be sleeved on the first main body portion 220, and the first gasket 610 may be located between the second end of the first elastic portion 300 and the nut 500. The first gasket 610 makes the connection between the second end of the first elastic portion 300 and the nut 500 more stable, and further makes the elastic force generated by the first elastic portion 300 to the first main body portion 220 more stable. Accordingly, a second gasket 620 may be disposed between the first end of the first elastic part 300 and the inner port of the first through hole 110, and the second gasket 620 may better connect the first end of the first elastic part 300 to the inner port of the first through hole 110.
Of course, after the installation is finished, in order to prevent the elastic force generated by the first elastic portion 300 from changing due to the looseness of the nut 500, the cable connector may further include a connection pin 700, the connection pin 700 may fix the position of the nut 500, specifically, the nut 500 may be provided with a first through hole and a second through hole, the first through hole and the second through hole may be distributed relatively, the first main body portion 220 may be provided with a third through hole corresponding to the first through hole and the second through hole, one end of the connection pin 700 may be in limit fit with an outer side end of the first through hole, and the other end of the connection pin 700 may sequentially pass through the first through hole, the third through hole and the second through hole and in limit fit with an outer side end of the second through hole. In this case, the connection pin 700 can fix the nut 500 at a position of the first body 220 to prevent the nut 500 from being loosened and the length of the cable from being effectively adjusted by the elastic force generated by the first elastic part 300.
