Embodiment
Embodiments provide a kind of cable cover(ing), decrease the situation that electric leakage occurs cable joint, and then reduce potential safety hazard.
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to accompanying drawing 1-4, the cable cover(ing) that the embodiment of the present invention provides comprises insulating base 1, and this insulating base 1 has the mounting groove that current supply cable joint 4 inserts, and the groove face of mounting groove has grounding parts, and cable joint 4 is electrically connected with the groove face of mounting groove after inserting mounting groove.
Cable joint 4 inserts in the mounting groove of insulating base 1 by the present invention after cable joint 4 is removed; and then make insulating base 1 be located on cable joint 4; and by the grounding parts of mounting groove by the ground connection of cable joint 4; achieve cable joint 4 to insulate and ground protection simultaneously; thus decrease the situation that electric leakage occurs cable joint 4; and then more effectively, safely, easily can protect workmen's safety, reduce potential safety hazard.
In the present invention one specific embodiment, cable cover(ing) also comprises for the cable joint 4 that leads with the insulating sleeve 2 making cable joint 4 accurately insert mounting groove, and this insulating sleeve 2 to be arranged on insulating base 1 and to have the perforation that current supply cable joint 4 penetrates.It should be noted that, above-mentioned perforation is identical with the bearing of trend of the mounting groove of insulating base 1, and the import of the outlet positive alignment mounting groove of perforation.The present invention makes cable joint 4 first penetrate in the perforation of insulating sleeve 2, under the guiding of insulating sleeve 2, then makes cable joint 4 be moved in mounting groove, be convenient to the insertion of cable joint 4, improve installation effectiveness; Above-mentioned insulating sleeve 2 can also play the effect of insulating protection to cable joint 4 simultaneously, reduce further potential safety hazard.
Preferably, above-mentioned mounting groove comprises groove 11 and the location notch 12 be arranged on inside groove 11; The radial dimension of groove 11 is greater than cylinder portion 42 diameter of cable joint 4 and is less than the width in the homalocephalus portion 41 of cable joint 4, and the groove face of groove 11 has the slot inserted for homalocephalus portion 41; The radial dimension of location notch 12 is greater than the width in homalocephalus portion 41, and length is greater than the length in homalocephalus portion 41.The slot that first the present invention makes the homalocephalus portion 41 of cable joint 4 aim at groove 11 inserts in groove 11, and cable joint 4 makes its whole homalocephalus portion 41 all move in location notch 12 to the inside, then rotatable cable joint 4, and homalocephalus portion 41 and slot are misplaced; Radial dimension due to groove 11 is less than the width in the homalocephalus portion 41 of cable joint 4, postrotational homalocephalus portion 41 is limited in location notch 12, and then achieve the radial location of cable joint 4, external force can be avoided to cause cable joint 4 to depart from the situation of insulating base 1, ensure that the reliability that cable joint 4 protects.In addition, the present invention can realize the location to cable joint 4 by rotatable cable joint 4, simple to operate, improves the installation effectiveness of cable joint 4.
For the ease of processing, above-mentioned groove 11 is preferably cylindrical groove, and the diameter of this cylindrical groove is greater than cylinder portion 42 diameter of cable joint 4 and is less than the width in the homalocephalus portion 41 of cable joint 4.The groove face of above-mentioned cylindrical groove is cylindrical shape, can coordinate preferably, be convenient to the rotation of cable joint 4 with the cylinder portion 42 of cable joint 4; The wearing and tearing to cable joint 4 can also be reduced.Other erose grooves 11 that above-mentioned groove 11 maybe can also make the cylinder portion 42 of cable joint 4 pass for oval groove 11.
Slot comprises the first slot 13 and the second slot 14 further, and both are oppositely arranged on the groove face of cylindrical groove, and the first slot 13 is identical respectively with size with the shape of the second slot 14.Now, the central axis of the first slot 13 and the second slot 14 opposed cylindrical groove is symmetrical arranged, and is convenient to processing; And can ensure that the cylinder portion 42 of cable joint 4 is positioned at the centre position of cylindrical groove, reduce the diameter of cylindrical groove, so, cable joint 4 rotates less angle just can realize location, locating effect is better simultaneously, can reduce the situation that cable joint 4 occurs to depart from.
In order to optimize technique scheme further, location notch 12 is cylinder groove, and the diameter of this cylinder groove is greater than the width in homalocephalus portion 41; Be convenient to processing; Interchangeable, above-mentioned location notch 12 can also be rectangular channel, elliptical slot or can current supply cable joint 4 homalocephalus portion 41 rotate other shaped recesses.
Because every bar cable is made up of multi-cable, the present invention makes that insulating base 1 has multiple mounting groove, and insulating sleeve 2 and mounting groove one_to_one corresponding.Every root cable joint 4 now in cable can insert in a mounting groove of insulating base 1 respectively, utilizes an insulating sleeve can realize the insulating ground of multi-cable, decreases the number of insulating sleeve, be easy to carry and install.Certainly, according to actual cable arrangement, insulating base 1 only can also arrange a mounting groove.
In the present invention one specific embodiment, insulating sleeve 2 is cylindrical sleeves, bores a hole as cylindrical hole, is convenient to processing, can coordinate preferably simultaneously, can also reduce the wearing and tearing to cable with cable joint 4.
For the ease of observing the position of cable joint 4, insulating sleeve 2 is connected with insulating base 1 by two arc plates 3, and is provided with inspection hole between two arc plates 3; That is have the space as inspection hole between arc plate 3, when inserting cable joint 4, operating personnel can observe the position of cable joint 4 by above-mentioned space, and then are convenient to the mounting or dismounting of cable joint 4.
Further, insulating base 1 is insulating rectangular block, and each mounting groove is evenly arranged along the length direction of insulating rectangular block.The present invention offers mounting groove on rectangular block, and structure is simple, is convenient to processing; And insulating rectangular block and bottom surface or other supporting surfaces are plane contact, stationarity is better.Above-mentioned insulating base 1 can also be cylindrical block, diamond block or other irregular shapes.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
