Cable connecting shell

The invention relates to a cable connecting shell, in particular to a cable connecting shell which is connected by a flexible shrink sleeve in the middle of the diverging connection. The invention can improve the operation in the prior art, is not easy to operate, and the cost is too high and the construction is improved. Different quality issues.

In the technical fields of various wired transmission industries such as telecommunications, cable television, and surveillance systems, optical cables have been used to transmit voice, data, and video information on a large scale; and optical cables that transmit information to various places are connected in cables. Connection and branching work in the shell. The cable connecting shells are provided with cable entry and exit end faces, and the cable entry and exit end faces are provided with cable inlet and outlet for the optical cable to pass through the cable inlet and outlet into the cable connecting shell for the connection and branching operation of the optical cable.

In the past, many optical cables were used for trunk trunks, and cable-connected shells were used for linear connection operations (the operation of connecting one cut-off cable to another cut-off cable), and the divergent operation (more than one) The cable of the core fiber is distributed into the connection of the plurality of cables with less core fibers. Therefore, the cable connecting the cable to the end face of the cable is provided with a plurality of cable inlets and outlets, and the inlet and outlet of one cable is usually provided for one cutoff. The cable enters and exits the cable to connect the shell.

Today's communication network has entered the era of broadband-to-home (FTTH) broadband services. Carriers must use the main optical cable that has been placed in various places to connect the cable along the way without intercepting the entire optical cable. The different optical fibers in the main optical cable are respectively connected (using the divergent optical cable) to the optical device of the user end; therefore, the cable connecting shell must be suitable for the in and out of the uninterrupted optical cable in addition to the cut-off optical cable. That is, it must be applied to the mid-span divergent connection operation (a backbone fiber cable with more core fibers. In the middle of the cable passing, when the user needs the fiber service, in the cable connection shell, a small Some unused optical fibers, after being connected to another divergent optical cable, are connected to new users, and most of the optical fibers in the trunk optical cable, especially those already used by other customers, cannot be cut off).

The waterproofing operation of the cable connection of the cable connection shell is very important, especially in the underground manhole and hand hole. The cable connection shell placed in it is immersed in water for a long time, so it must not seep water, otherwise it will not seep. Once the water penetrates into the cable connection shell, it is normal to use the fiber for more than 20 years, which only takes several years to deteriorate and embrittle, which affects the quality of broadband signal transmission.

The cable connecting shell in the prior art, the cable entering and exiting the cable entering and exiting the end face and entering the cable of the cable connecting shell, and the commonly used waterproof processing method between the cable inlet and outlet, including bolt mechanical and hot There are three types of contracted and elastic shrink sleeves. Among them, the bolt mechanical parts are complicated, the process is cumbersome, and the cost is high; while the heat-shrinking type has a low cost, the heat-shrinkable tube of the plastic material is required to be fired during construction, which may generate poison gas and cause accidents, and The construction quality is difficult to be consistent, and it is easy to be affected by the bending and twisting of the cable, which is more suitable for the environment of overhead and wall hanging, and is not suitable for the underground cable used in the hole of the long-term water; the construction method of the elastic shrink sleeve It is the most convenient and rapid, the construction quality is consistent, the waterproof effect is good, and the cost of materials is low. Therefore, it is the best choice to use the elastic shrink sleeve method for waterproof treatment.

Because the cable connection shell for the cable inlet and outlet waterproof treatment with the elastic shrink sleeve, the cable inlet and outlet end faces must be formed with a circular or elliptical hollow tubular string for the cable to be connected to the cable. When the cable for the continuous operation enters and exits the connecting shell, and the waterproof shrinkage processing is performed by the elastic shrink sleeve, the portion which is contracted and covered by the elastic shrink sleeve must have a circular cross section of the outer non-recessed slit and a column having one of an elliptical shape (for example, a cable having a circular cross section disposed on an end face of the cable and a cable or the like of a circular or elliptical hollow tubular string, and The cross-section is a circular cable), in order to have a good waterproof effect; however, the cable connection box for the cable inlet and outlet waterproof treatment with the elastic shrink sleeve is to be carried out in the middle of the divergent connection operation. In the case of connecting the cables of the divergent connection in the middle, the cable pair of the part to be connected to the diverging connection must be bent into a U-shape, and then in the form of a double cable, without first cutting off the cable. Into the bullet Shrinking the sleeve, and then passing through a hollow tubular string (ie, cable inlet and outlet) on the inlet and outlet end of the cable connecting the cable to the cable connecting shell to carry out the diverging operation in the middle, and the U-shaped double strip The cross-section of the cable is two kinds of circles of different centers. After shrinking and shrinking directly with the elastic shrink sleeve, there must be a gap and it is not waterproof; therefore, the U-shaped double cable must be elasticized. Shrink sleeve coating The position of the water-repellent treatment, firstly, the joint waterproofing auxiliary device is used to form a first waterproof structure between the two cables without a recess and a slit having a circular or elliptical-like cross section, and then The U-shaped double cable is first inserted (passed) through the elastic shrink sleeve, and then the U-shaped double cable is passed through a hollow tubular string on the end face of the cable of the cable connecting shell (ie, The cable inlet and outlet) enters the connecting shell (the first waterproof structure must have a portion that does not penetrate the hollow tubular string), and the elastic shrink sleeve is shrink-wrapped to the outside of the hollow tubular string and The outer surface of the first waterproof structure that does not penetrate the hollow pipe column has a recessed slit-like circular or elliptical cylinder to form a second waterproof structure, thereby completing the cable connection box When diverting the diverging operation, the elastic shrinkage casing is used to carry out the waterproof treatment between the divergent connecting cable and the cable inlet and outlet.

In the prior art, the manner in which the first waterproof structure is formed by the joint waterproofing auxiliary device includes:

1. Only use waterproof adhesive (belt) with adhesiveness and plasticity. A large number of double-wound cables wrapped around the U-shaped cable will be waterproofed with elastic shrink sleeves, and hand-molded into a small cross section. A cylinder having a circular or elliptical shape to form the first waterproof structure; but the disadvantages include: the shape and size of the circular or elliptical cylinder which is molded by each person each time, and the degree of no depression And so on, the results can not be the same every time, resulting in the problem of different construction quality, and after the completion of the kneading, before being contracted by the elastic shrink sleeve, it may be collided or squeezed at any time during the construction process. Deformation.

2. Before each cable of the U-shaped double cable is to be waterproofed by the elastic shrink sleeve, an appropriate amount of viscous and plastic waterproof tape is wound on each cable, and then a rigid fixture of a circular or elliptical cylinder having a cross-section with no recessed slits, which is combined with the two cables, is bolted to form the first waterproof structure. Although the method can avoid the problem of different construction quality, the disadvantages include: complicated parts, complicated procedures, difficult operation and high cost, and the continuous radial contraction force of the elastic shrink sleeve cannot be fully utilized, and the rigid fixture is maintained. The tightness of the fit between the two cables.

In summary, the global telecommunications and other related industries have begun to use a large number of optical cables. To replace the traditional cable, and make extensive use of the cable connection box and a large number of mid-way divergence operations, when the different optical fibers in the main optical cable are respectively connected (using the divergent optical cable) to the optical equipment of the user end, if the above-mentioned conventional knowledge can be improved In the technology, the cable connection casing leads to the diverging connection cable to elastically shrink the casing for waterproof treatment, the operation is not easy, the cost is too high, and the construction quality is not the same, and research and exploration produce a newer and more advanced The cable splicing shell which is simpler in operation, lower in cost and more consistent in construction quality, and can fully utilize the continuous radial contraction force of the elastic shrink sleeve to maintain the tightness of the first waterproof structure, can certainly enhance the fiber of the related industry. The quality of the network construction.
