Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector processing technology, and in particular to a short wire demolding tool. Background Technology

[0002] Figure 5 A schematic diagram of an MT-MT fiber optic connector is shown. The connector includes multiple optical fibers 1, each with a fiber core 15 at both ends. A housing 10 is fitted over both ends of the optical fibers 1, and multiple fiber optic jacks 14 are formed within the housing 10. The fiber cores 15 are inserted into the fiber optic jacks 14. A window 13 is formed on the upper wall of the housing 10, extending through to the fiber optic jacks 14. A raised edge 16 is formed on the inner end of the housing 10, which has a rectangular block structure. The outer contour of the raised edge 16 is larger than the outer contour of the housing 10. A rectangular sheath 11 is formed on the inner end face of the housing 10, and the optical fibers 1 pass through the rectangular sheath 11, with one end of the fiber optic jacks 14 extending to the rectangular sheath 11. During the curing process, the housing 10 and the optical fibers 1 often shift relative to each other, affecting the yield rate of the MT-MT fiber optic connector. Existing curing trays used for placement have poor fixation properties. Utility Model Content

[0003] This utility model provides a short-line demolding fixture to overcome the shortcomings of the prior art, and solves the problems of low yield rate and inconvenience in demolding MT-MT fiber optic connectors during curing. It has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A short-line demolding fixture includes a lower mold and an ejector pin below the lower mold. Both the lower mold and the ejector pin are elongated structures.

[0005] Furthermore, the lower wall of the lower mold is provided with a groove, the lower end of the groove is open, and a pair of elongated holes are provided at the bottom of the groove; The upper wall of the lower mold has a protrusion, and an elongated hole passes through the upper wall of the protrusion. Multiple placement slots are evenly spaced along the length of the protrusion, and the two ends and the top of the placement slots are open.

[0006] Furthermore, inner grooves are provided at both ends of the inner wall of the placement groove, and the inner grooves are located directly above the elongated hole.

[0007] Furthermore, the depth of the groove at both ends is greater than the depth of the middle section, and the middle section of the groove is located between the elongated holes.

[0008] Furthermore, the groove has openings at both ends along its length.

[0009] Furthermore, the bottom edge of the elongated hole is formed with an outwardly expanding inclined wall.

[0010] Furthermore, the ejector includes a base plate, the upper wall of which is formed with an upper protrusion that passes through a groove. The upper wall of the upper protrusion is symmetrically formed with inner inserts along the centerline of the width direction of the base plate. The inner inserts pass through elongated holes. The upper wall of the inner inserts is formed with top blocks in an equally spaced array along its length direction. The top blocks pass through each pair of inner grooves located at the same end and arranged opposite each other.

[0011] The advantages of the above technical solution are: This invention firstly uses each placement groove to limit and constrain the two sides of the housing, and most importantly, it uses the inner groove to limit and constrain the two ends of the convex edge. This limiting method prevents the housing and optical fiber from moving relative to each other, thus affecting the quality of the optical fiber connector.

[0012] Secondly, the ejector block inserted into the inner groove acts on the protruding edge of the fiber optic connector, thereby causing the fiber optic connector to move out of the placement groove, thus achieving the purpose of rapid demolding. Furthermore, during the demolding process, since each fiber optic connector is ejected simultaneously, it avoids pulling that could affect the connection stability between the fiber and the housing, and also avoids damaging the fiber itself. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0018] Figure 5 A schematic diagram of the MT-MT fiber optic connector structure is shown. Detailed Implementation

[0019] like Figures 1-5 As shown, a short-line demolding fixture includes a lower mold 3, and an ejector 2 is provided below the lower mold 3. Both the lower mold 3 and the ejector 2 are elongated structures.

[0020] The lower mold 3 has a groove 30 on its lower wall, with an opening at the lower end and openings at both ends along its length. A pair of elongated holes 31 are formed at the bottom of the groove 30, with the bottom edges of the elongated holes 31 forming inclined walls that expand outwards. The upper wall of the lower mold 3 has a protrusion 35, through which the elongated holes 31 penetrate. Multiple placement grooves 33 are evenly spaced along the length of the protrusion 35, with openings at both ends and the top. Inner grooves 34 are formed at both ends of the inner wall of the placement groove 33, located directly above the elongated holes 31. The groove depth at both ends of the placement groove 33 is greater than the depth in its middle section, and the middle section of the placement groove 33 is located between the elongated holes 31. This design prevents the fiber optic cable 1 from sagging and deforming due to gravity, thereby improving the bonding effect of the fiber optic connector.

[0021] The ejector 2 includes a base plate 20. The upper wall of the base plate 20 is formed with an upper protrusion 21. The upper protrusion 21 passes through the groove 30. The upper wall of the upper protrusion 21 is symmetrically formed with an inner insert 22 along the center line of the width direction of the base plate 20. The inner insert 22 passes through the elongated hole 31. The upper wall of the inner insert 22 is formed with top blocks 23 in an equally spaced array along its length direction. The top blocks 23 pass through each pair of inner grooves 34 located at the same end and arranged opposite each other.

[0022] In this embodiment, during operation, the operator sequentially inserts the fiber core 15 of the optical fiber 1 into the optical fiber jack 14, and at this time, the end of the optical fiber 1 is located in the rectangular sheath 11. After insertion, the connector is placed in the placement slot 33. At this time, the optical fiber 1 will be placed flat on the middle section of the placement slot 33, and the rear protrusion 16 is locked in each pair of inner grooves 34.

[0023] Then, the fiber optic connector is cured. After curing, the operator places the lower mold 3 on the ejector 2, and at the same time, the upper protrusion 21 is inserted into the groove 30. Then, by pressing the lower mold 3, the top block 23 moves upward relative to the lower mold 3. During the movement, its upper end will act on the protrusion 16, thereby ejecting all the fiber optic connectors in the placement groove 33.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
