Abstract
The utility model discloses a flexible fireproof cable pre-branched coupler, comprising a copper pipe shell. A main cable and a branch cable are packaged in the copper pipe shell and connected through an insulated coupling head. The terminals, penetrating out of the copper pipe shell, of the main cable and the branch cable are provided with metal compressing rings. Each of the metal compressing rings is shaped like a bell mouth and the opening of the bell mouth faces outwards. According to the flexible fireproof cable pre-branched coupler provided by the utility model, the bell mouth-shaped metal compressing rings are arranged at the terminals, so that the cables are effectively prevented from being pulled and becoming loose, and the reliable coupling of the main cable and the branch cable is guaranteed. Moreover, the flexible fireproof cable pre-branched coupler is simple in structure and easy to implement.
Description
Technical field
The utility model relates to a kind of cable coupler, relates in particular to the pre-branch of a kind of flexible fire-proof cable coupling.
Background technology
Existing cable coupler, when carrying out leader cable and branch cable connection, a general mode of only pressing " T connects " connects, and to join a connect box, and node stability is difficult to ensure the card consistency, time-consuming taking a lot of work, easily be subject to tractive to cause node contact resistance variation and fault.Therefore be necessary the existing cable coupling is improved.
The utility model content
Technical problem to be solved in the utility model is to provide the pre-branch of a kind of flexible fire-proof cable coupling, can guarantee leader cable and branch cable positive connection, and simple in structure, easy to implement.
The utility model is to solve the problems of the technologies described above the technical scheme adopted to be to provide the pre-branch of a kind of flexible fire-proof cable coupling, comprise the copper pipe housing, be packaged with leader cable and branch cable in described copper pipe housing, described leader cable is connected by the insulation coupling head with branch cable, wherein, the terminal head place that described leader cable and branch cable pass the copper pipe housing is provided with the compression of metals ring, and described compression of metals ring is bell mouth shape and iiared port is outside.
The pre-branch of above-mentioned flexible fire-proof cable coupling, wherein, part and leader cable that described branch cable is stretched out the copper pipe housing are arranged in parallel.
The pre-branch of above-mentioned flexible fire-proof cable coupling, wherein, described leader cable and branch cable are aluminum conductor, the outside of described aluminum conductor is coated with the copper layer.
The pre-branch of above-mentioned flexible fire-proof cable coupling, wherein, described compression of metals ring is fixedly linked by clamp nut and terminal head.
The utility model contrast prior art has following beneficial effect: the pre-branch of the flexible fire-proof cable that the utility model provides coupling, by the compression of metals ring of bell mouth shape is set at the terminal head place, thereby effectively prevent from that cable from being pullled and cause getting loose, guarantee the effective conducting ground connection of copper pipe of main, as to prop up cable copper outer jacket with pre-bifurcation connector simultaneously, guarantee leader cable and branch cable positive connection, and simple in structure, easy to implement.

Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the pre-branch of the utility model flexible fire-proof cable joiner structure schematic diagram.
Refer to Fig. 1, the pre-branch of the flexible fire-proof cable that the utility model provides coupling comprises copper pipe housing 1, be packaged with leader cable 2 and branch cable 3 in described copper pipe housing 1, described leader cable 2 is connected by insulation coupling head 4 with branch cable 3, wherein, terminal head 5 places that described leader cable 2 and branch cable 3 pass copper pipe housing 1 are provided with compression of metals ring 6, and described compression of metals ring 6 is bell mouth shape and iiared port is outside.
The pre-branch of the flexible fire-proof cable that the utility model provides coupling; Adopt the copper pipe housing, described leader cable 2 and branch cable 3 are aluminum conductor, and the outside of described aluminum conductor is coated with the copper layer, can effectively prevent fires; By the compression of metals ring 6 of bell mouth shape is set at terminal head 5 places, make the cable stretched out there is the certain flexibility bending, thereby effectively prevent from that cable from being pullled and cause getting loose, guarantee leader cable 2 and branch cable 3 positive connection, and simple in structure, easy to implement.
In order further to guarantee part that leader cable and branch cable positive connection, described branch cable 3 stretch out copper pipe housing 1 preferably and leader cable 2 is arranged in parallel; Described compression of metals ring 6 can be fixedly linked by clamp nut 7 and terminal head 5.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; within not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
