With the development of mobile communication technology and the vigorous development of the comprehensive layout of 5G technology, the efficient and fast installation of communication equipment and communication cables has become a necessary competitive advantage for manufacturers in the field, and attention is paid to outdoor protection, especially bird pecking prevention protection of cables and equipment in severe environments while ensuring efficient installation. However, there is currently no good solution to meet these two requirements in terms of jumper devices that require disassembly and assembly.

At present, an outdoor installation mode of the jumper wire needs to disassemble an end connector to expose the jumper wire, so that the jumper wire has enough long operable space to be installed. For the convenience of disassembly, a section of operable space is usually reserved when the component is protected in the early stage, and the section cannot be protected, but after the component is disassembled and installed, the protection outside the jumper is affected, so that the jumper protection is not in place. There is another measure in the industry: a protection part is added for secondary protection, so that the manufacturing cost is increased, and the working efficiency is greatly reduced.

As shown in fig. 1 and 2, the retractable jumper protection device according to the preferred embodiment of the present invention includes a retractable jumper protection assembly 10, where the jumper protection assembly 10 includes two different sizes of protection sleeves and a protection sleeve adapter, the two different sizes of protection sleeves are respectively a larger size protection sleeve 1 and a smaller size protection sleeve 2, the outer diameter of the larger size protection sleeve 1 is larger than the outer diameter of the smaller size protection sleeve 2, and the inner diameter of the larger size protection sleeve 1 is also larger than the outer diameter of the smaller size protection sleeve 2, and one end of each of the protection sleeves is connected to two ends of the adapter 3, and the other end of each of the protection sleeves is connected to a first connector 41 and a second connector 42.

As shown in fig. 3, the adapter 3 includes three parts: the large-aperture end 31, the small-aperture end 32 and the intermediate connecting section 33, wherein the inner diameter of the large-aperture end 31 is larger than that of the small-aperture end 32, the large-aperture end 31 is connected with the protective sleeve 1 with a large specification, the small-aperture end 32 is connected with the protective sleeve 2 with a small specification, and the intermediate connecting section 33 is conical and is connected between the large-aperture end 31 and the small-aperture end 32. The adapter 3 has a central through hole and the bore of the central connecting section 33 is a tapered bore 330.

During assembly, one end of the protective sleeve 1 with a larger specification is inserted into the large-aperture end 31 of the adapter, and when the protective sleeve 1 with a larger specification is inserted into the tapered hole 330, the protective sleeve 1 with a larger specification cannot be inserted into the adapter 3 without limitation due to the gradually reduced aperture of the tapered hole 330, so that the tapered hole 330 of the intermediate connection section 33 plays a role of a stop surface. Adapter 3 sets up buckle 34 on big aperture end 31, this buckle 34 and the cooperation of great specification protective casing 1 for fixed great specification protective casing 1, specifically, great specification protective casing 1 adopts the bellows, and its surface has the recess, and buckle 34 is the elasticity buckle, and its card is in the recess, makes great specification protective casing 1 can remove in to adapter 3, nevertheless can not extract and break away from adapter 3. In other embodiments, the buckle may also adopt other structures as long as it can prevent the protective sleeve 1 of a larger specification from being pulled out of the adapter 3. In other embodiments, the intermediate connection section may be omitted, and the large-bore end and the small-bore end of the adapter are directly connected, and the intermediate interface between the two inner bores is used to limit the inward unrestricted movement of the protective sleeve of larger gauge.

In the small bore end 32 of adapter was inserted to the one end of less specification protective sheath pipe 2, because the middle through-hole of adapter 3 was followed small bore end 32 and is gone to big bore end 31 grow gradually, consequently, less specification protective sheath pipe 2 can continue to stretch into in adapter 3, also can pass adapter 3, stretch into in the protective sheath pipe 1 of great specification, overlap with the protective sheath pipe 1 part of great specification, this state is the shrink state of jumper wire protection subassembly promptly.

In the preferred embodiment, the other ends of the

protective sleeves

1 and 2 are respectively connected to the first connector 41 and the second connector 42, and the jumper assembly 5 sequentially passes through the second connector 42, the jumper protection assembly 10 and the first connector 41. In a normal state, that is, in a state where the jumper protection assembly 10 is not retracted, the overall length of the jumper protection assembly 10 is greater than the length of a jumper to be protected; when the jumper wire needs to be installed, the small-specification protective sleeve 2 of the jumper wire protection assembly is retracted towards the adapter 3 and the inside of the large-specification protective sleeve 1, the second connector 42 fixedly connected with the small-specification protective sleeve 2 moves along with the small-specification protective sleeve 2, and therefore the jumper wire assembly 5 is exposed. After the installation is completed, the second connector 42 and the protective tubing 2 of smaller gauge are pulled back to the initial position, connecting the second connector 42 to the adapter. In other embodiments, the other ends of the larger format protective sleeve 1 and the smaller format protective sleeve 2 may also be connected to a fixture or other equipment that needs to be connected.
