The low-voltage live electric (dismantling) meter is the most common work of distribution network marketing team personnel, and the exposed phase line and zero line conductor part needs to be insulated in the working process so as to protect personal and equipment safety.

Example one

As shown in fig. 1, the present invention provides a temporary insulation protective sleeve, which can place an exposed wire in the temporary insulation protective sleeve, and comprises a base body 1 and a cover body 2, wherein the base body 1 is provided with a threading hole, the wire is inserted into the threading hole, the cover body 2 can be covered on the base body 1 to seal one end of the threading hole, it can be understood that one side of the cover body 2 is provided with an opening, the cover body 2 is provided with a contraction driving portion 21, and when the cover body 2 is covered on the base body 1, the contraction driving portion 21 is pressed against the outer wall of the base body 1 to contract the threading hole, so as to clamp the wire. It can be understood that the base body 1 and the cover body 2 are made of insulating materials. Optionally, the base body 1 and the cover body 2 are made of ABS, so that the insulation requirement of a low-voltage distribution network is met.

The temporary insulating protective sleeve is convenient to use, avoids winding of an insulating tape on a lead, improves the insulating level, reduces the electric shock risk, effectively ensures the safety of people and equipment, and improves the working efficiency.

In this embodiment, for the phase sequence of more convenient difference wire, the spraying is yellow green red black etc. colour on the lid 2, and different wires adopt the interim insulating protective sheath of different colours.

Specifically, in order to make it more convenient and reliable to press from both sides the dress wire, pedestal 1 includes tightening part 11 and the first installation department 12 of interconnect, and the through wires hole runs through tightening part 11, still is provided with second installation department 22 on the lid 2, and second installation department 22 is connected with shrink drive division 21, and when second installation department 22 lock joint in first installation department 12, shrink drive division 21 supports and presses the outer wall of tightening part 11, makes the through wires hole shrink.

More specifically, in order to facilitate the installation of the cover body 2 and the seat body 1, the threading hole penetrates through the tightening portion 11 and the first installation portion 12, and it can be understood that the axis of the tightening portion 11 coincides with the axis of the first installation portion 12, so that the second installation portion 22 is more conveniently sleeved on the first installation portion 12.

In other embodiments, the first mounting portion 12 is disposed on a side surface of the tightening portion 11 and provided with a first mounting hole, the second mounting portion 22 is disposed on a side surface of the contraction driving portion 21 and provided with a second mounting hole, and when the contraction driving portion 21 is covered on the tightening portion 11, the first mounting portion 12 and the second mounting portion 22 are fixedly connected by bolts passing through the first mounting hole and the second mounting hole.

More specifically, in order to facilitate the installation of the cover body 2 and the seat body 1 more and to make the installation more firm, the first installation portion 12 is provided with an external thread portion, the second installation portion 22 is provided with an internal thread portion matched with the external thread portion, and the first installation portion 12 and the second installation portion 22 are fastened by means of thread connection.

More specifically, this interim insulating protective sheath is still including rubber ring 3, and first installation department 12 still is provided with first bellying, and rubber ring 3 cover is located on the external screw thread portion and is leaned on first bellying, and it can be understood that, when first installation department 12 and second installation department 22 threaded connection, first installation department 12 supports simultaneously with second installation department 22 and presses rubber ring 3, and rubber ring 3 has elasticity, can prevent effectively that the screw thread from becoming flexible. Optionally, the rubber ring 3 is an O-ring.

Further, for facilitating the relative rotation of the cover body 2 and the seat body 1, and further enabling the threaded connection to be fastened, the second mounting portion 22 is provided with a second protruding portion, and the first protruding portion and the second protruding portion are both set to be polygonal, so that the rotation is more convenient and faster. In the present embodiment, the polygon is a hexagonal structure.

More specifically, in order to clamp the wire more effectively by tightening part 11 and prevent the wire from coming off tightening part 11, tightening part 11 is provided with a plurality of through grooves. It will be appreciated that the through slots provide space for the tightening part 11 to contract the wire.

Further, in order to fix the wires more firmly, the temporary insulating protective sleeve further comprises an anti-slip ring 4, the anti-slip ring 4 is arranged in the tightening part 11, and when the tightening part 11 is compressed, the anti-slip ring 4 can be contracted to fix the wires. It can be understood that the friction between the anti-slip ring 4 and the wire is larger, so that the wire is not easy to fall off. In this embodiment, the material of the anti-slip ring 4 is acetate fiber, and the acetate fiber has the characteristics of high viscosity, insulation, flame retardance and the like.

Furthermore, because the tightening part 11 has ductility, the slip-proof ring 4 is installed in two sections, the first section of slip-proof ring 4 is installed in the tightening part 11 for clamping the wires, and the second section of slip-proof ring 4 is installed in the first installation part 12 to abut against the first section of slip-proof ring 4 for supporting the first section of slip-proof ring 4.

Specifically, the contraction driving portion 21 includes an inclined portion for contracting the threading hole to clamp the wire when the cover body 2 is placed on the seat body 1, and a straight tube portion connected to the inclined portion for accommodating the wire.

Example two

The present embodiment provides a temporary insulating protective sheath, which has a structure substantially the same as that of the first embodiment, and for convenience, only the differences from the first embodiment will be described.

As shown in fig. 2, compared with the first embodiment, the contraction driving portion 21 of the present embodiment only includes an inclined portion, when the cover body 2 is covered on the seat body 1, the inclined portion contracts the threading hole to clamp the wire, and the wire is placed in the inclined portion, so that the structural design is simpler and the processing is more convenient.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
