Description

Communication cable connection distribution case with connection part, hollow pipe column and connected part

technical field

The present invention relates to a communication cable connection branch case with a connecting part, a hollow pipe column and a connected part, especially a communication cable connection branch case which improves the waterproof method of the incoming cable, so as to strengthen its function , Improve construction quality and construction safety, reduce the cost of the operator, and can solve the lack of functions, uneven construction quality, increased maintenance and operation costs of the operator, and construction safety caused by the cable waterproof method of connecting the communication cable to the cable housing in the prior art and many other issues.

Background technique

In the technical field of various wired transmission industries such as telecommunications, cable television, and monitoring systems, it is necessary to use copper (electric) cables and optical cables for communication to transmit voice, data, and image information, and to transmit information to communication cables everywhere. The connection and branching operations are carried out in the communication cable connection branch case. Because the copper conductor or optical fiber that transmits information in the communication cable will affect the transmission quality, cause transmission obstacles and accelerate the aging of the copper conductor and optical fiber in the environment of high humidity and water immersion, so the communication cable is coated with The waterproof and moisture-proof protective layer and the waterproof and moisture-proof cable jacket, however, the cables that are connected and split in the communication cable connection and distribution shell must be stripped off the waterproof and moisture-proof protective layer on the outside of the conductor before proceeding. Connection and branching operations, so the communication cable connection branch case must have a waterproof and moisture-proof function to protect the cables entering the communication cable connection branch case for connection and branching operations from being damaged by water seepage or moisture (wet). Affect transmission quality, cause transmission obstacles and accelerate the aging of copper conductors and optical fibers. Since the deployment of communication cables in all countries in the world is as far as possible underground, and the underground cables are mainly laid out in pipes, so a large number of communication cable connectors must be placed in underground cable pipes. Many manholes and handholes are full of water all the year round, so the communication cable connection sub-housings placed in them are also soaked in water all the year round. Many communication cables with poor construction or poor waterproof function The junction box is often blocked by water seepage and must be replaced. Therefore, the better the waterproof and moisture-proof effect of the communication cable connection cable housing, the better the transmission quality of the cable can be guaranteed, the transmission barrier can be avoided, the service life of the cable can be extended, the maintenance and replacement cost of the operator can be reduced, and the investment benefit can be increased.

According to the difference in the waterproof method between the entrance and exit for the cable to pass through the cable entry and exit end face of the communication cable connection branch case in the prior art, there is a heat-shrinkable communication cable connection branch case. There are three types: mechanical communication cable connection branch housing and elastic shrink tube type communication cable connection distribution case; among them, the heat shrinkable communication cable connection distribution case is equipped with a heat-shrinkable waterproof cable entry and exit end face, The heat-shrinkable waterproof method is to use heat-shrinkable tubes, bifurcated clips and other parts to grill the heat-shrinkable tubes with a gas blowtorch, and form a hollow tube column on the end surface of the cable and pass through the hollow tube column to enter the communication cable. A waterproof structure is formed between the cables connected to the branch housing, and its advantages include functionally suitable for the branch connection of the trunk cable, straight line connection operation and distribution (branch) cable connection operation, fewer components, and material cost Low, but its disadvantages include the use of gas blowtorch barbecue heat shrinkable tubes for construction, which affects labor safety and public safety, time-consuming construction, high construction costs, difficulty in controlling the temperature of gas blowtorch barbecue, inconsistent construction quality resulting in inconsistent waterproof effects, maintenance and The cost of replacement is the highest; while the mechanical communication cable junction box is equipped with a mechanically waterproof cable entry and exit end face, the mechanical waterproof method is to use a tight-fitting shell, tightening screws, adhesive and Plastic waterproof glue, elastic body waterproof gasket and other components form a tight waterproof structure between the cable inlet and outlet of the cable inlet and outlet end face and the cable by applying a tight external force with a tool. Its advantages Including functionally suitable for branching and straight-line connection operations of trunk cables and distribution (branch) cable connection operations, construction does not require fire and high safety, but its disadvantages include many parts, high manufacturing costs, and complicated construction procedures , High construction cost, complex process lead to different construction quality, affect waterproof effect, high maintenance cost and other problems; and elastic shrink tube type communication cable connection distribution case is equipped with elastic shrink tube waterproof cable in and out The end face, the elastic shrink tube waterproofing method is to use the elastic shrink tube part, after removing the hard plastic threaded tube lined with the elastic shrink tube wall, the hollow tube column formed on the end face of the cable entering and leaving and passing through the center A waterproof structure is formed between the cables that enter the communication cable connection sub-housing through the empty pipe column. The elastic shrinkage tube is elastic with high elongation, high tensile strength and good elastic recovery rate. It is made of silicone rubber or ethylene propylene diene monomer (EPDM) or ethylene propylene rubber (EPR). Elastic shrink tube, a part of the elastic shrink tube (expanded hole diameter) is put on the outside of the hollow tube column formed by the end surface of the cable inlet and outlet, and the other part is put on the cable connecting through the hollow tube column After removing the hard plastic threaded tube lining the wall of the elastically shrinkable tube outside the cable jacket at the outer end of the hollow column, the elastically shrinkable tube returns to a smaller aperture close to the enlarged aperture, and The smaller aperture is smaller than the outer diameter of the hollow tube And the outer diameter of the cable, by the radial elastic contraction force of the elastic contraction tube, the elastic contraction tube is tightly wrapped around the cable entering and exiting the hollow column at the end surface and the cable passing through the hollow column The cable connected to the outer end of the hollow pipe column is formed into a tightly bundled waterproof structure, which has the advantages of being functionally suitable for the straight line connection operation of the main cable and the connection operation of the distribution (branch) cable, with the least number of parts and materials. Low cost, the simplest construction, the lowest construction cost, the construction quality is least affected by human factors, the construction quality consistency is high, the waterproof effect is good, the maintenance cost is the lowest, the construction does not need fire and the safety is high, but its disadvantage is that it is not suitable for The main cable with a large outer diameter, especially the midway connection and branching operation of the main optical cable; although the heat-shrinkable waterproof cable enters and exits the end face, the straight line connection operation of the main cable and the distribution (branch) cable connection operation can also be used. The elastic shrinkable tube is waterproof, but when the main cable must be diverted and connected in the middle, it must be waterproofed by heat shrinkage, and it must face the adverse effects caused by the shortcomings of heat shrinkable waterproofing, and the limited area of cable access The end face is only enough to form a limited number of hollow pipe strings. When the limited hollow pipe strings are occupied by straight-line trunk cables, the number of hollow pipe strings that can be used to distribute (branch) cables in and out will be reduced. Thereby reducing or even not being enough to use, and forming a heat-shrinkable waterproof trunk cable inlet and outlet on the end face of the waterproof cable in the elastic shrink tube mode for the trunk cable to be diverted and connected midway, and the same problem will also be faced.

Therefore, if many deficiencies such as lack of function, high cost, inconsistent construction quality and construction safety in the prior art can be improved, not only the construction quality and construction safety can be improved, but also the cost of the industry can be greatly reduced. Construction and maintenance costs.

Therefore, the inventor of the present invention, in view of the defects produced in the prior art, has carefully studied and explored, and with a persistent spirit, finally conceived the present invention with a connecting portion, a hollow pipe string, and a connected portion. The communication cable is connected to the branch case, and the following is a brief description of the present invention.

Contents of the invention

In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a communication cable connection distribution case with a connecting part, a hollow column and a connected part. The communication cable connection distribution case includes: at least one cable The cable inlet and outlet end surface, and the at least one cable inlet and outlet end surface is formed with at least one connecting portion and at least one first hollow column for the communication cable to pass through the at least one cable inlet and outlet end surface and enter the communication cable connection distribution case , and the communication cable that is about to pass through the at least one first hollow column is prepared to use an elastic shrink tube to form a waterproof structure; and at least one connected part, and the at least one connected part is not formed on the at least one cable In and out of the end face, and the at least one connected part is selected from the first part to be waterproofed in a mechanical way, the second part to be waterproofed in an elastic contraction tube, and a combination thereof. A waterproof structure is formed between the communication cables connecting the communication cables to the branch housing, and the at least one connected portion can be combined with the at least one connecting portion to form a waterproof structure. Since the communication cable is connected to the waterproof method of the sub-wiring case and the cable, the best choice is to use the elastic shrinkable tube waterproof method, which has more advantages and fewer disadvantages than the heat shrinkable method and the mechanical method. Its advantages include the fewest parts and low material cost. , the simplest construction, the lowest construction cost, the least influence of construction quality by human factors, high consistency of construction quality, good waterproof effect, lowest maintenance cost, no need for fire in construction, high safety, etc. The cable inlet and outlet end faces of the wire casing are formed with a first hollow pipe column for the communication cable to pass through the hollow pipe column to enter the communication cable connection branch casing, and to be waterproof in the form of an elastic contraction tube; because the main cable is especially When the trunk optical cable is connected to the branch connection in the middle, it passes through the cable inlet and outlet of the end face of the cable without cutting off the cable, and enters the communication cable connection branch case, so the trunk cable of the branch connection is connected in the middle , it is not suitable to go in and out of the communication cable connecting branch case through the hollow column waterproof in the way of elastic contraction tube, so the cable entry and exit end surface of the communication cable connection branch case of the present invention is formed with a connection for cable entry and exit The connection part is not only suitable for the cable entry and exit of the straight line connection and branch connection, but also suitable for leading the trunk cable of the branch connection in the middle, passing through the connection part and entering the communication cable connection distribution case without being cut off. It is not suitable to use the elastic shrink tube waterproof method for the main cables that are diverted and connected in the middle, and the best choice for the waterproof method is that the heat shrinkable waterproof method has more advantages and disadvantages than the heat shrinkable waterproof method. Less mechanical methods of waterproofing, its advantages include the controllability of construction quality and construction safety are much better than heat-shrinkable methods, etc. Therefore, the communication cable connection branch case of the present invention also includes a connected part, and the The connected part can be selected from the first part prepared to be mechanically waterproof, and the connected part of the first part can not only be connected with the communication cable that is about to pass through the connecting part and enter the communication cable connection distribution case. Form a waterproof structure, and can be combined with the connection part to form a waterproof structure; since the communication cable is connected to the inside of the distribution case, it is used for the fixing, accommodation, configuration and component parts of the main cable, especially the main optical cable. The location, cable wiring space, matching direction, bending radius standard, etc. have their established models and technical requirements. Therefore, the position of the main cable inlet and outlet of the cable inlet and outlet end faces must be coordinated with the connection and distribution of communication cables. The design and planning of the inside of the cable housing is set at the most appropriate position, and it is not suitable for arbitrary transformation. Therefore, whether it is a branch connection or a straight line connection in the middle, the position where the main cable enters and exits the end face of the cable is the best choice. They should all be the same cable inlet and outlet, so the connecting part of the cable inlet and outlet end face of the communication cable connection branch housing of the present invention is not only suitable for mechanically waterproofing the trunk cable inlet and outlet of the diverging connection in the middle, but also It is also the best cable inlet and outlet for straight-line or terminal-branched trunk cables, and the best waterproof method for straight-line or terminal-branched trunk cables has more advantages than mechanical methods. less elastic shrink tubing Therefore, the connected part of the communication cable connection distribution case of the present invention can also be selected from the second part prepared to be waterproof in the form of an elastic contraction tube, and the connected part of the second part can not only be connected with the The connection part enters the communication cable of the communication cable connection branch case to form a waterproof structure, and can be combined with the connection part to form a waterproof structure; therefore, the communication cable connection branch case of the present invention can be used according to Different methods of cable connection and branching, choose the waterproof method with the best function, cost, quality and safety conditions, so as to overcome the shortcomings of the existing technology. In addition, although in order to make the trunk cables connected by straight lines or branched terminals can also be waterproofed by adopting an elastic shrink tube method better than the mechanical waterproof method, the trunk cables connected by straight lines or branched terminals can also choose to pass through the communication system of the present invention. The cable is connected to the first hollow column formed by the cable entry and exit end face of the distribution case and is waterproofed by elastic shrinkage tubes. However, in order to match the change of the position of the main cable entrance and exit, it is necessary to adjust and change the connection of the communication cable. The wiring facilities inside the distribution case, what's more, the smaller the volume of the communication cable connection distribution case, the more convenient it is to accommodate and install, and the more the number of cable inlets and outlets on the end face, the more convenient it is to connect cables. Line connection and branching operations, but due to the limited area of the cable entry and exit end faces, only a limited number of first hollow pipe columns can be formed for cable entry and exit, and a limited number of first hollow pipe columns are directly connected to the trunk After the cables are occupied, the number of the first hollow columns that can be used to distribute (branch) cables in and out will be reduced or even not enough. Therefore, the cable inlet and outlet end faces of the communication cables of the present invention are connected to the branch housing to form a The connecting part can not only be used for the branch connection of the main cable in the middle, but also can be used for the straight line connection or terminal branch connection of the main cable.

Furthermore, the communication cable connection distribution case of the present invention further includes at least one connecting portion where the second hollow column is formed on the at least one cable inlet and outlet end surface. Since many trunk cables are connected in straight lines and terminal branches, and the second hollow column is formed at the connection part of the cable inlet and outlet end faces, the connected part of the second part only needs to use an elastic shrink tube on the It is enough to form a tight waterproof structure between the second hollow pipe column at the connection part of the cable inlet and outlet end faces and the main cable. The connecting part is combined with the connected part of the mechanically waterproof first part. After removing the second hollow pipe column formed on the inner edge of the connecting part on the cable inlet and outlet end faces, the connecting part can be used The connected part of the first part of mechanical waterproofing is combined to carry out the waterproofing operation of leading the branch trunk cable in the middle; therefore, the second hollow column of the communication cable connection branch case of the present invention is formed on the cable entry and exit end surface When the connection part of the cable is connected, not only the preparation of the second hollow pipe column not formed on the cable inlet and outlet end surface in the second part can be saved, but also the connection of the second hollow pipe column not formed on the cable inlet and outlet end surface with the second hollow pipe column can be saved.
