Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1-3, a high-voltage multi-core cable intermediate connector includes a first sleeve 1, a second sleeve 2, a terminal tube 3, a connection terminal 4, a wire clamping sliding sleeve 5, a wire clamping sliding block 6, and a first sleeve 1 and a second sleeve 2 having the same shape and size, wherein the first sleeve 1 and the second sleeve 2 are fixed to two sides of the terminal tube 3 by screws, the connection terminal 4 is disposed inside the terminal tube 3, one end of each of two cables is fixed to two sides of the terminal tube 3 by passing through the two second sleeves 2, cable cores of the two cables are connected by the terminal tube 3, the wire clamping sliding sleeve 5 is sleeved on inner walls of the first sleeve 1 and the second sleeve 2, a tapered groove is formed in the middle of the wire clamping sliding sleeve 5, a notch with a larger inner diameter of the tapered groove faces the terminal tube 3, eight grooves are formed in an outer edge of the wire clamping sliding sleeve 5, so that a plurality of cable cores pass through and are connected to the connection terminal 4, the wire clamping slide block 6 is movably sleeved in the conical groove, a through groove is formed in the middle of the wire clamping slide block 6, the conical surface of the wire clamping slide block 6 is matched with the inclination of the inner wall of the conical groove, one end of an electric wire cable core penetrates through the through groove in the middle of the wire clamping slide block 6 from one side of the wire clamping slide sleeve 5 and winds back to one side of the wire clamping slide sleeve 5, then penetrates out of a groove in the outer edge of the wire clamping slide sleeve 5 and is fixed on the connecting wire terminal 4, another electric wire cable core in the second sleeve 2 is fixed on the terminal pipe 3 in a similar way and is suspended at high altitude after being straightened by a cable, under the action of the self gravity, a pulling force towards the wire clamping slide block 5 is applied to the wire clamping slide block 6, so that under the action of the pulling force, the inclined plane of the wire clamping slide block 6 is matched with the conical groove surface in the middle of the wire clamping slide sleeve 5 to clamp the cable core, and the larger the, the connection part of the cable core and the connecting terminal 4 is prevented from being pulled, the cable core is stably fixed on the connecting terminal 4 and cannot fall off, and the wire clamping sliding block 6 and the wire clamping sliding sleeve 5 effectively clamp each cable core, so that the contact area of clamping the cable core is increased, and the clamping effect is improved.
Wherein, the inner chamber of first sleeve pipe 1 and second sleeve pipe 2 is movable sleeve respectively and is equipped with clamp plate 7 that is located double-layered line sliding sleeve 5 one side, and movable sleeve is equipped with clamp plate 8 between the lateral wall of clamp plate 7 and the 1 inner chamber of first sleeve pipe, 8 suits of clamp plate are in the outside of cable, clamp plate 8 is in compression state, utilize clamp plate 8's elasticity, make the cable core that the side cooperation double-layered line sliding sleeve 5 of clamp plate 7 pressed from both sides tight this department, the tight effect of clamp of cable core has further been improved, and simultaneously, when two cables received external wind-force etc. and constantly dragged, clamp plate 8's elasticity can effectively be cushioned, thereby prevent that the wiring end of cable and cable core from being broken, further ensured the stable connection of two cables in the intermediate junction ware.
Wherein, the lateral wall of 1 inner chamber of first sleeve pipe is equipped with the bellows that is located the spring inside, and the bellows keeps away from on the one end of 1 inner wall of first sleeve pipe passes through the fixed cover cable of lock nut, utilizes the bellows to seal, prevents in the first sleeve pipe of external rainwater infiltration, influences the normal transmission work of cable, simultaneously, does not influence the cable and receive external force to drag the effect and rock to effectual utilization clamp plate 8's elasticity is cushioned.
Wherein, the inner wall of the conical groove in the middle of the wire clamping sliding sleeve 5 and the outer surface of the wire clamping sliding block 6 are both provided with soft bulges, so that the friction force of the wire clamping sliding sleeve 5 and the wire clamping sliding block 6 for extruding the cable wire is increased, the clamping degree of the cable wire is further improved, and the soft bulges can not damage the cable wire.
When in use, one end of two cables is firstly peeled, the length of the peeled cable core wire is only required to ensure that the cable sheath is arranged at one side of the locknut in the inner cavity of the first sleeve 1, each cable core wire passes through a certain degree from the side surface of the first sleeve 1, the locknut sleeve is screwed and fixed, the pressing plate 8 and the pressing plate 7 are sleeved into the first sleeve 1 in sequence, each cable core wire passes through the tapered groove in the middle of the wire clamping sliding sleeve 5 and simultaneously passes through the through groove in the middle of the wire clamping sliding block 6, then one side of the wire clamping sliding block 6 is wound back to one side of the wire clamping sliding sleeve 5 through the tapered groove, and then the cable core wire passes through the groove on the outer edge of the wire clamping sliding sleeve 5 and is fixed on the connecting wire terminal 4 by a screw, meanwhile, the wire clamping sliding block 6 is sleeved into the tapered groove in the middle of the wire clamping sliding sleeve 5, the cable outside the first sleeve 1 is pulled, so that the, and (3) hermetically connecting the first sleeve 1 with the terminal pipe 3, and similarly connecting the cable of the second sleeve 2 on the other side of the terminal pipe 3.
