Description

  The present invention relates to a fiber optic connector pedestal, and more particularly, to a dustproof gate piece of the fiber optic connector pedestal.

Fiber optic connectors are a new product, currently used for externally mating another connector, thereby placing a plug-in or terminal in an outer body or cradle. The fitted connector is placed in the receiving table.
The connector is always installed, and if it is not installed, it will not prevent dust from entering the connector insertion opening of the cradle, resulting in poor insertion or poor signal, affecting transmission signal quality . Therefore, a gate piece must be installed in the cradle opening to prevent dust from entering.

A known optical fiber connector outer body having a gate piece is as shown in FIG. 1 and is obtained by assembling a lid, a spring, a gate fan, and an outer body. This spring is a single-stage torsion spring type having a middle winding. Therefore, when facing the gate piece, the pressing force is imbalanced. At the same time, assembling is complicated and difficult, and the cradle has an increased thickness connected to the gate piece, which results in a large volume, which is not suitable for products requiring lightness and shortness.
Taiwan Notice No. 500233 Patent "Light emitting receiver connecting joint structure"

In another known example, a pivot shaft is inserted into both side holes of a single torsion spring and a gate fan. In this method, apart from the above-mentioned torsion being unbalanced, the components are too fine. Therefore, simply inserting the pivot shaft into the hole of the spring and the gate piece increases the processing cost. Further, since the protruding step is positioned on the pivot shaft as described above, the height is increased, and it is difficult to reduce the volume.
Japanese Patent No. 3440022 "Optical Fiber Connector"

    The problem to be solved is that the spring uses a single torsion spring, so that the torsion becomes unbalanced, and the protruding gate piece is located on the pivot axis, which is disadvantageous for pursuit of lightness and shortness. Is a point.

  In the present invention, an optical fiber joint is connected, and is composed of an outer body, a gate piece, an elastic part, and a stop piece. The outer body forms a storage space at the front end, in which the optical fiber connector is stored. Positioning grooves are formed on both sides of the storage space, and a concave chamber is formed behind the positioning groove. The gate piece is provided with at least one hooking ridge. The resilient component includes at least one arc-shaped body, a connecting end, a first end and a second end, wherein the arc-shaped body fits into the engaging ridge and couples with the portal piece. Opening and closing of the gate piece is controlled by the coaxial structure of the gate piece and the elastic component. The main feature of the stop piece is that it is inserted into the positioning groove to fix the first end and the second end of the elastic component.

    The optical fiber connector pedestal of the present invention has the advantage that the pressing force is stabilized and the volume is reduced by controlling the opening and closing of the dustproof gate by the coaxial structure.

  2, 3 and 4 are a three-dimensional exploded view and an assembly instruction diagram of the present invention. As shown in FIG. 2, the optical fiber connector receiver of the present invention mainly includes an outer body 10, a gate piece 20, It is composed of the elastic part 30 and the stop piece 40 and assembled.

A storage space 101 is formed in the outer body 10 and receives an optical fiber plug (not shown). Further, positioning grooves 102 (see FIG. 4) are formed on both sides of the storage space 101, and a concave chamber 104 (see FIG. 4) is formed behind the positioning grooves 102, and optical components are stored therein. A plurality of convex points 105 are formed in the concave chamber 104 (see FIG. 4).
The gate piece 20 is a plastic gate piece (not limited to plastic), on which at least one hooking ridge 21 is installed, and in this embodiment, two hooking ridges 21 are installed. ), A projection 22 is provided on the bottom. In addition, a protruding uppermost convex portion 106 is provided on the uppermost surface of the outer body 10 and plays a role of positioning when assembled into a product.

  The elastic part 30 is made of metal or other plastic material, and includes arc-shaped main bodies 31 and 33, a connecting part 32, a first end 34 and a second end 35. Among them, the arc-shaped main bodies 31 and 33 are fitted to the engaging ridges 21 and connected to the gate pieces 20. The first end 34 and the second end 35 are inserted into the positioning groove 102, and the connecting portion 32 controls opening and closing of the gate piece. Since the elastic part 30 of the present invention is formed by the two arc-shaped bodies 31 and 33, one spring is installed on one side as in a known optical fiber connector to prevent the pressing force from being unbalanced.

    As shown in FIG. 2, the stop piece 40 is not limited to metal, and is fixed to the positioning groove 102 on the outer body 10 by the first end 34 and the second end 35 of the elastic component 30.

  FIG. 4 is an assembled sectional view of the embodiment. As shown in the figure, when assembling into an optical fiber connector, first, the arc-shaped main bodies 31 and 33 of the elastic part 30 are respectively fitted into the engaging ridges 21 of the gate piece 20, and then the stop piece 40 is positioned from outside the gate piece 20. When fitted in the direction of the groove 102, the first end 34 and the second end 35 of the gate piece 20 and the elastic part 30 are fixed in the positioning grooves 102 on the outer body 10, respectively. The present invention is completed when the optical component is incorporated into the concave chamber 104. After the assembly is completed, the connecting portion 32 of the elastic component 30 is bent downward and hits the gate piece 20. The two torsion springs control the opening and closing of the gate piece 20 by equalizing the pressing force.

FIG. 4 is a view showing a known optical fiber connector receiver assembly instruction. FIG. 3 is a three-dimensional exploded view of the optical fiber connector receiver according to the embodiment of the present invention. FIG. 3 is an assembly instruction diagram of the optical fiber connector receiver according to the embodiment of the present invention. FIG. 4 is an assembled sectional view according to an embodiment of the present invention.
