Description

Improve the electrical protective sleeve of structure

The utility model relates to a kind of electrician's articles for use, relates to a kind of electrical protective sleeve or rather.

The range of application of electrical protective sleeve is quite widely, especially in factory and building, because required electric power is bigger, must connect larger-size electrician's line and to avoid the short circuit initiation fire, in addition for avoiding taking place too much the dangerous situation of misconnection because of wiring, also must use electrical protective sleeve to protect, so electrical protective sleeve have considerable status in electrical field.

Electrical protective sleeve commonly used covers junction A1 and the less line segment A2 that covers forms by bigger shown in the A among Fig. 1, Fig. 2, the electric wire B1 of electrician's line B and the joint cover of joint C overlay in the junction A1, and electrician's line B then is covered by and covers in the line segment A2.The assembling of this electrical protective sleeve A and electrician's line B and joint C can be referring to Fig. 3, earlier line segment A2 being covered in the lower end of electrical protective sleeve A is coated on electrician's line B, again with the pressing block C1 crimping of electric wire B1 in electrician's line B and joint C, electric wire B1 and joint C are integrated, mobile at last electrical protective sleeve A, make crimping place that junction A1 cover overlays on electric wire B1 and pressing block C1 of covering of electrical protective sleeve A upper end, promptly finish whole assembly workings.At this moment, the line segment A2 that covers of electrical protective sleeve lower end still is coated on outside electrician's line B, crimping place of the pressing block C1 of electric wire B1 in electrician's line B and joint C can be short-circuited etc. because of foreign material fall into, the problem of misconnection electrician line also can not take place, so this electrical protective sleeve there is advantage safe in utilization, easy to assembly.

But use through reality, this electrical protective sleeve still has following deficiency: the first, because the covering line segment bigger coating face can not be provided of electrical protective sleeve lower end, thereby when assembling must first electrical protective sleeve be nested with on electrician's line just can with coupling compression joint, in case forget and be nested with sheath, then can't be inserted in sheath again from the joint and remedy, because it is less that line segment is covered in the lower end of electrical protective sleeve, must cut off electrician's line and re-assembly, the end of a thread of cutting-out and joint have to abandon, and cause waste; It two is, the restriction that is subjected to joint or binding element that connects owing to electrician's line, add the difference of junction point and joint distance, for the misconnection problem must not take place in convenient for maintaining, the electrician often is enclosed within the two ends of single line to distinguish mutually with other electrician's line with homochromy electrical protective sleeve, if junction point or joint spy are many, then must join a lot of electrician's lines, increased the possibility of misconnection relatively, and for the sheath solid colour that makes electrician's line two ends often will be changed sheath, and since the sheath lower end to cover line segment less, can not be simply sheath be taken off and has to destroy original electrician's line from electric wire, wasted material and man-hour; It three is, because the line segment that covers of electrical protective sleeve lower end can be quite little for the scope of expansion, and the size range of electrician's line is relatively large, cooperates with it for making things convenient for use that multiple sheath must be set, the both uneconomical scope of application that has also limited it.

The purpose of this utility model is a kind of electrical protective sleeve that improves structure of design, makes the line segment that covers of sheath that bigger coating scope be arranged, and can coat electrician's line of large and small size, and sheath can put easily or take off, no matter which kind of application feature electrician's line is under.

The purpose of this utility model is achieved in that the electrical protective sleeve that improves structure, by the upper end cover junction and lower end cover line segment in conjunction with constituting, cover tip side greater than covering line segment, it is characterized in that:

The described line segment that covers is provided with concavo-convex alternate longitudinal channels, covers line segment perisporium waviness.

Because the line segment that covers of electrical protective sleeve is provided with concavo-convex conduit, make and cover line segment and had extendible coating face, not only can coat electrician's line of different size, also electrical protective sleeve optionally can be put or takes off from the joint of electrician's line, it is extremely convenient to use.

Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing.

Address before the explanation of Fig. 1 to Fig. 3, repeat no more.

Referring to Fig. 4, Fig. 5, the upper end of improving the electrical protective sleeve 1 of structure cover junction 11 and traditional electrical protective sleeve A to cover junction A1 identical, covering of its lower end then offers the concavo-convex alternate longitudinal channels 121,122 in some roads on the line segment 12, this conduit makes the perisporium that covers line segment form waveform, thereby has increased the coated scope of covering line segment 12.

During winding, before crimping electrician line B and joint C, can electrical protective sleeve 1 be nested with on electrician's line B earlier, because the line segment 12 that covers of electrical protective sleeve 1 lower end is provided with multiple tracks conduit 121,122, increased expanding surface, therefore, electrician's line B can be set on covering in the line segment 12 of electrical protective sleeve hypomere like a cork, again electrician's line B1 is placed in the pressing block C1 of joint C, with both pressings and one.

Referring to Fig. 6, electrical protective sleeve of the present utility model also can be by winding shown in Figure 6.If first crimping remember just behind joint C and the electrician's line B that having forgotten to be nested with the electrician expands and overlap 1, can be with the upper end cover people of electrical protective sleeve 1 from joint C, because the line segment 12 that covers of electrical protective sleeve 1 lower end is provided with the multiple tracks conduit, thereby make and cover line segment 12 and have expandable functions, therefore work as joint C and wear man-hour by covering line segment 12 places, cover line segment 12 and expand because of placing of joint C, for joint C by bigger passage is provided; In like manner if will take out sheath 1, only need electrical protective sleeve 1 is pulled out to the direction of joint C from electrician's line B, because the electrical protective sleeve lower end is covered line segment 12 and is provided with conduit, can expand it and coat area, thereby, when covering line segment 12 and pulled out to joint C place, the line segment 12 that covers of electrical protective sleeve 1 lower end is strutted by joint C and bigger passage is provided, and electrical protective sleeve 1 can successfully be taken off from joint C.

Referring to Fig. 7, electrical protective sleeve 1 after the winding, because covering on the line segment 12 of its lower end have conduit, cover line segment 12 and have extendible coating scope and make, thereby, if the size of electrician's line B just with cover the big or small suitable of line segment 12, then can utilize and cover the recessed conduit of line segment 122 and coat electrician's line B, when the size of electrician's line B was big, this covered line segment 12 and is strutted to coat electrician's line B, its coating scope can be strutted fully to conduit 121,122, thereby can coat electrician's line of multiple size.

In sum, improvement structure of the present utility model truly has advantage simple in structure, easy to use.
