Abstract

The utility model discloses a novel optical fiber terminal, which is characterized by comprising a base, a spring, a dust-proof sheet, an upper cover, an optical fiber chip and pins, wherein the spring, the dust-proof sheet and the upper cover are assembled together and are inserted in the base; the base is provided with a chip fixing groove, the optical fiber chip is inserted in the chip fixing groove and the dust-proof sheet is positioned above the optical fiber chip; and the pins are clamped on the base. According to the optical fiber connector disclosed by the utility model, the adopted dust-proof plate can rebound automatically, no plastic rear cover is needed, the front end of the base directly sinks below a PCB board, the operation is convenient and space is saved; and the pins are fixed by fixing grooves and positioning buckles on the outer side of the base, and the metal pins can be inserted in a plugboard more stably and are more resistant to high temperature.

Description

A kind of novel optical fiber terminal

Technical field

The utility model belongs to fiber optic communication field, relates to a kind of novel optical fiber terminal.

Background technology

The development of digital technology is so that optical fiber communication becomes the trend of communication development.The existing fiber terminal structure comprises pedestal, plastic cement bonnet, fiber chip, plastic cement dust cap as shown in Figure 1.At first fiber chip is lain in the base bottom chip pickup groove during assembling, then utilize the fixedly buckle above the plastic cement bonnet to match with fixed card slot on the pedestal, fiber chip is fixed, utilize at last in the optical fiber cable preformed hole on the plastic cement dust cap insertion pedestal, prevent that dust from entering.It is larger in use to take up room, and plug plastic cement dust cap repeatedly will be extracted the plastic cement dust cap when using Optical fiber plug simultaneously, turn back to again after using, and complex operation, the plastic cement dust cap is also lost easily.Simultaneously owing to use the leadless process welding, require product can bear welding temperature roughly about 260 °, cause easily the distortion of plastic cement pin.Therefore need a kind of novel optical fiber terminal of design, easy to operate, it is little to take up space, high temperature resistant, convenient and swift during use, elegant in appearance.

The utility model content

Technical problem to be solved in the utility model provides a kind of novel optical fiber terminal, use the dustproof sheet that automatically rebounds, do not need the plastic cement bonnet, the pedestal front end directly sinks under the pcb board, easy to operate, save the space, utilize simultaneously pickup groove and the locating button fixed piece on earpiece in the pedestal outside, pin is more steady when plate, and is high temperature resistant.

The technical solution of utility model is as follows:

A kind of novel optical fiber terminal is characterized in that, comprises pedestal, spring, dustproof sheet, loam cake, fiber chip, pin;

Described spring, dustproof sheet, loam cake are assembled together and are inserted in the pedestal;

Described pedestal has the chip pickup groove, and described fiber chip is plugged in the chip pickup groove, and described dustproof sheet is positioned at the fiber chip top;

Pin is installed on the pedestal.

Have the U-shaped coil on the described spring, have U-lag on the described dustproof sheet, the U-shaped coil on the described spring places in the U-lag on the described dustproof sheet;

The relative both sides of described loam cake inside are provided with two pickup grooves, and the relative both sides of described dustproof sheet are equipped with turning axle, and turning axle places in the described pickup groove.

Have locating button on the described pedestal, have the positioning through hole suitable with this locating button on the described pin, the locating button on the described pedestal buckles in the positioning through hole on the described pin.

Beneficial effect:

The utility model optic fibre connector uses the dustproof sheet that automatically rebounds, and does not need the plastic cement bonnet, the pedestal front end directly sinks under the pcb board, and is easy to operate, saves the space, utilize simultaneously pickup groove and the locating button fixed piece on earpiece in the pedestal outside, pin is more steady when plate, and is high temperature resistant.

Embodiment

Below with reference to the drawings and specific embodiments the utility model is described in further details:

Shown in Fig. 2-5, a kind of novel optical fiber terminal is characterized in that, comprises pedestal, spring, dustproof sheet, loam cake, fiber chip, pin;

Pin is installed on the pedestal.

The utility model utilizes the coil above the spring to cooperate with plastic cement pillar above the dustproof sheet, and the turning axle at dustproof sheet two ends cooperates with the pickup groove at two ends in the loam cake, and the realization dustproof sheet rebounds afterwards automatically in compression, allows user's more convenient operation.Directly utilize in addition loam cake and pedestal that fiber chip is located, saved the plastic cement bonnet.Simultaneously the pedestal front end directly sinks under the pcb board, has saved fiber-optical socket shared space on employed product.Utilize pickup groove and the locating button fixed piece on earpiece in the pedestal outside, pin is more steady when plate, and the experience high-temperature soldering can be out of shape.
