Description

A kind of rubber-insulated wire optic fibre fixing device

(1) technical field

The utility model relates to a kind of rubber-insulated wire optic fibre fixing device.

(2) background technology

The development of internet, people online have become the one way of life demand, along with high-definition network video, and the popularizing of big game, people are increasing to the complaint of the network speed of existing ADSL online.A kind of speed of people's exigence is network access faster, and light wave transmissions is the good solution of high speed information transmission network, and optical fiber is the light wave transmissions medium.For obtaining the high speed information transmission network, play an important role in the mechanical optical fiber connector fiber entering household, a rubber-insulated wire optic fibre fixing device that clamps rubber-insulated wire optical fiber is arranged on the optical fiber splicer.

There is the earliest the people to propose a kind of flip-shell chuck in the drawing stage, as described in Figure 7, comprise a box body, be provided with the optical fiber cavity that front and back are penetrating in the described box body, be provided with a pair of clamping limb of embracing optical fiber cavity in the described box body, also be provided with the jacking block space between the limit wall of described clamping limb and box body; Be pivoted with on the described box body one relatively box body dig or fixed cap is combined in lid on the box body, described lid is provided with jacking block; When described lid covers on box body, described jacking block coupling is filled in the compression clamp gripping arm to the optical fiber cavity campaign in jacking block the space in, and for fixing, this flip-shell chuck employing be that the mode of fixture block, draw-in groove links together.Fixture block 1A draw-ingroove 1B is the head that is placed in the flip-shell chuck design time at the beginning, but this part is the Hookean region of whole flip-shell chuck just, lid and box body press together firmly in this place, even the bottom offers angle, also dial not open, sofixture block 2A and draw-ingroove 2B were the rear sides that is positioned at whole flip-shell chuck in actual production afterwards, as shown in Figure 8, namely near the articulated section.And when design the articulated section structure be to adopt to establish protruding pivot on the box body, establish the mode of axis hole on the lid, break lid during installation into two with one's hands and be articulated on the box body.In actual use, when the connection broken into two with one's hands betweenfixture block 2A and the draw-ingroove 2B, lid also can separate with box body thereupon, does not have the effect that is pivoted at all.

(3) summary of the invention

Arrange unreasonable in order to overcome existing rubber-insulated wire optic fibre fixing device fixture block and draw-in groove when clamping, not can realize the being pivoted deficiency of function, the utility model provide a kind of lid really to be hubbed on the box body and can block the rubber-insulated wire optic fibre fixing device on the box body of being installed in of dismantling.

The technical scheme in the invention for solving the technical problem is: a kind of rubber-insulated wire optic fibre fixing device, comprise a box body, be provided with the optical fiber cavity that front and back are penetrating in the described box body, be provided with a pair of clamping limb of embracing optical fiber cavity in the described box body, described clamping limb is provided with the clamping tooth towards that face of optical fiber cavity, also is provided with the jacking block space between the limit wall of described clamping limb and box body; Also comprise a lid, described box body is provided with pivot outward, and described lid is provided with the pivot hole, described lid by pivot be arranged in mode on the pivot hole be hubbed on the box body and relatively box body dig or fixed cap is combined on the box body, described lid is provided with jacking block; When described lid covers on box body, described jacking block coupling is filled in the jacking block space compression clamp gripping arm to the optical fiber cavity campaign; Described lid front end is provided with elastic hook, and described box body front end downside is provided with bayonet socket, and described lid is crossed the mode that the box body front end is stuck on the bayonet socket by elastic hook and is fixed on the box body.

For ease of making, described clamping limb is arranged on the cramping body that is embedded in box body.

Further optimize, described elastic hook has between two and two elastic hooks and leaves optical-fibre channel; Described box body front end is provided with sunken groove, and when covering, described elastic hook is absorbed in the groove.

For ease of the location of rubber-insulated wire optical fiber, described box body is extruded with catch towards optical fiber cavity, is provided with hole slot in the described catch, and described catch is used for blocking the rubber-insulated wire section so that accurate positioning when installing.

Further increase the fixedly fastness of rubber-insulated wire optical fiber, described box body is provided with first towards optical fiber cavity and stings tooth, and described lid is stung tooth towards optical fiber cavity correspondence first and is provided with second and stings tooth; When described box body and lid covered, described first stings tooth, second stung the interlock of tooth trend.When rubber-insulated wire optical fiber was arranged in optical fiber cavity, first stings tooth and second stung tooth and can firmly bite rubber-insulated wire optical fiber.

The rubber-insulated wire optical fiber connector is divided into rubber-insulated wire section and fiber segment.

The utility model in use end of rubber-insulated wire optical fiber pierces in the optical fiber cavity in the box body, then the lid fixed cap is combined on the box body, and jacking block is filled in the driving clamping limb in jacking block the space in and clamped the rubber-insulated wire section, and described rubber-insulated wire optical fiber just can firmly be fixed on the box body.

The beneficial effects of the utility model are: the stationary installation of box body and lid adopts the elastic hook of being located at the lid front end, and so just having avoided needs laterally firmly to peel off lid and box body, thereby lid and box body really realize articulating function.
