Description

Communication insulated cable inner core locator

Technical Field

The invention relates to the technical field of cable inner core positioning, in particular to a communication insulated cable inner core positioner.

Background

1. Understanding that: a communications cable is a cable that transmits telephone, telegraph, facsimile documents, television and radio programs, data and other electrical signals. Is formed by twisting more than one pair of mutually insulated wires. Compared with an overhead open wire, the communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality and the like.

When the communication cable is used in outdoor, underground and other severe environments, or in the process of installation and transportation, the communication cable is inevitably subjected to extrusion, collision, bending and other conditions, because the inner core of the communication cable is formed by twisting a plurality of mutually insulated wires, cable cores inside the communication cable are easily connected together when being pressed, and the situations that signals cannot be transmitted and even short circuits are possibly caused exist.

2. And (3) retrieval: relevant patents such as the positioning of the inner core of the cable are searched in a patent library, and more than ten patents are searched. Among them, the following two are similar to the technical problems and technical features to be solved by the present application.

3. Citation: the invention discloses an inner core positioning sheet for an overhead insulated cable in a patent with the Chinese patent number of 202210711085, and relates to the technical field of cable inner core positioning, and solves the problem of poor positioning effect in the process of wrapping a conventional cable chip.

To summarize: for this related art patent, the inventors consider here: this patent is when fixing a position many inner cores, at first need take out spacing cardboard, fill in T type groove with fastening area one end again after, fill in spacing cardboard again in the ann jack, later personnel take a plurality of locating plates of fastening area other end winding, later personnel pull fastening area one end hard, fill in T type inslot once more at last, it is spacing to carry out the centre gripping to it through the grip block, operating procedure is comparatively loaded down with trivial details, and only carry on spacingly through the fixed band to fixation clamp and inner core, when tightening up the fastening area through manual, not only waste physical power, and the dynamics is difficult to hold, when the dynamics of bundling is not enough, the locating rack can be followed the connecting rod and slided from beginning to end, two locating rack distances are far away, then can not be fine play the location effect to the inner core between two locating racks, it can not be applicable to the cable of different models to have this patent again, cable inner core diameter is different, need to produce the support frame and the packing cover that are applicable to different diameters.

Citation: in the patent of chinese patent No. 202022972478, an inner core spacer for overhead cable is disclosed, including the spacer main part, inner core positioning groove has all been seted up to four inside sides of spacer main part, and inner core positioning groove is semi-circular structure, mounting groove has all been seted up to both ends inside around the inner core positioning groove inner wall, and mounting groove internal connection has fixed glue film, the radian and the internal diameter of fixed glue film all equal with inner core positioning groove's radian and internal diameter, spacer main part outer wall is circular arc structure. This inner core spacer for aerial cable can be quick with the neat of aerial cable inner core put together that flushes, convenient follow-up processing improves and puts efficiency. This inner core spacer for aerial cable can fix a position the aerial cable inner core through the semi-circular inner core positioning groove of four sides of spacer main part, and can consolidate the position of aerial cable inner core through the fixed glue film, improves the installation stability of aerial cable inner core.

To summarize: for this related art patent, the inventors consider here: this patent is fixed a position the position of aerial cable inner core through fixed glue film, fixed glue film has the instability, meet water, the condition such as being heated can all lose viscidity, make inner core and spacer break away from, and this aerial cable only supports the location from the inner core inboard with the inner core spacer, can't guarantee the roundness in the cable outside, need have the spacer that has different diameter inner core positioning groove according to the bore production of cable inner core again, can't adjust to the inner core of different bores.

Therefore, the present invention provides a core locator for insulated communication cables to solve the above problems.
