Description

Technical Field

[0001] The present invention relates to the field of fiber optic connectors, and particularly to a four-part type riveting press for fiber optic connectors. Background Art

[0002] A riveting press utilizes a stamping machine device and a special connecting die through an instantaneously strong high-pressure processing process. Based on the cold extrusion deformation of the material of the plate itself, a stress-free concentrated internal inlaid dot with a certain tensile and shear strength is formed, and thus two or more layers of materials with different materials and different thicknesses can be connected. A fiber optic connector, also known as a fiber optic adapter (also called a flange), is an important connecting component in fiber optic erection. During the connection process of the fiber optic connector, a riveting press is required.

[0003] Currently, the existing riveting presses for fiber optic connectors are mainly pneumatic up-and-down opening and closing type riveting presses or manual up-and-down opening and closing type riveting presses. Under the drive of air pressure or manual pressure, forming and riveting are performed through a circular two-half type forming jig, and the Kevlar wire of the optical fiber is press-fitted and connected with the riveting ring of the fiber optic connector. However, both of these two riveting presses have the following deficiencies:

[0004] 1. The precision control of the stamping stroke of the pneumatic downward pressing structure or the manual downward pressing structure is relatively poor. The size of the riveting ring cannot be guaranteed after riveting. In some cases, the riveting force is too large, resulting in a relatively flat riveting ring. In some cases, the riveting force is insufficient, resulting in a poor bite connection effect between the riveting ring and the Kevlar wire. The tensile strength of the product is poor, that is, the consistency is relatively poor, resulting in unstable connection quality of the fiber optic connector after riveting.

[0005] 2. The roundness of the riveting ring cannot be guaranteed after riveting, and it is easily riveted into an elliptical shape. Subsequently, when the tail sleeve of the fiber optic connector is pushed and sleeved on the riveting ring, it will be too tight or too loose. When it is too tight, it affects the appearance of the product. When it is too loose, the tail sleeve of the fiber optic connector is easily detached, losing its function of keeping the optical fiber wire from bending.

[0006] 3. The contact surface between the riveting ring and the Kevlar wire is relatively smooth after riveting, and the contact surface between the riveting ring and the tail sleeve is also relatively smooth, with small frictional resistance. It is easy for the riveting ring and the Kevlar wire to become loose, and the tail sleeve of the fiber optic connector is also easily detached. Summary of the Invention

[0007] To solve the problems in the prior art, the present invention provides a four-part riveting press for an optical fiber connector. By providing a driving mechanism, a control mechanism, a support base, and a riveting mechanism that cooperate with each other in the four-part riveting press, the control mechanism can adjust the specific distance and pressure of the stamping stroke to complete high-precision automatic riveting. After riveting, the size consistency of the riveting ring is good, and the quality stability of the riveted product is good. The four-part pressing method of the riveting groove closing from four directions towards the middle to press the Kevlar wire of the optical fiber and the riveting ring can ensure that the roundness of the riveting ring after riveting is better and the connection with the tail sleeve is more stable. The embossed pattern in the riveting groove can enhance the friction between the riveting ring and the Kevlar wire after riveting, and can also enhance the friction between the riveting ring and the tail sleeve, greatly improving the connection quality of the optical fiber connector and solving the problems of unstable stamping stroke, unstable connection quality between the riveting ring and the Kevlar wire after riveting, and unstable connection quality between the riveting ring and the tail sleeve in the pneumatic up-and-down opening and closing riveting press or the manual up-and-down opening and closing riveting press on the current market.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] As shown in Figures 1 - 5 the figure, a four-way riveting press for an optical fiber connector provided by the present invention includes a driving mechanism 1, a control mechanism 2, a support base 3 and a riveting mechanism 4.

The riveting mechanism 4 includes an upper riveting module 41 and a lower riveting module 42 which are symmetrically separated up and down. The upper riveting module 41 is fixedly connected to the upper riveting support connecting plate 11, the lower riveting module 42 is fixedly arranged on the lower riveting support connecting plate 31. Each of the upper riveting module 41 and the lower riveting module 42 is provided with two diagonal slide rails. A riveting slider 43 is slidably connected to the diagonal slide rails. The riveting slider 43 is fixedly connected with a riveting pressing block 44. The riveting pressing block 44 is provided with an arc-shaped riveting groove 45. The riveting groove 45 is adapted to the riveting ring 51 of the optical fiber connector 5. The riveting groove 45 is provided with raised pressing patterns. In this embodiment, the driving mechanism can drive the upper riveting module to press down, and then drive the four riveting sliders to slide along the diagonal slide rails when the riveting groove touches the riveting ring, so as to drive the riveting pressing block and the riveting groove to close from four directions to the middle to press and fit the Kevlar wire 62 of the optical fiber 6 and the riveting ring 51. Among them, the control mechanism can adjust and control the specific distance and pressure of the stamping stroke to complete high-precision automatic riveting. After riveting, the size consistency of the riveting ring is good, and the quality stability of the riveted product is good. The four-way pressing method of the riveting groove closing from four directions to the middle to press and fit the Kevlar wire of the optical fiber and the riveting ring can ensure that the roundness of the riveting ring after riveting is better and the connection with the tail sleeve 52 is more stable. The pressing patterns pressed on the riveting ring by the pressing patterns in the riveting groove can enhance the friction force between the riveting ring and the Kevlar wire 62 layer after riveting, and can also enhance the friction force between the riveting ring and the tail sleeve, greatly improving the connection quality of the optical fiber connector.

[0027] As shown in Figures 2 - 3As shown, a downward pressing and resetting elastic device 46 is provided between the riveting slider 43 and the upper riveting module 41, an upward rising and resetting elastic device 47 is provided between the riveting slider 43 and the lower riveting module 42, and separating and resetting elastic devices 48 are provided between the two riveting sliders 43 slidably connected within the upper riveting module 41 and between the two riveting sliders 43 slidably connected within the lower riveting module 42.

[0028] As Figures 2 - 3 shown, the sliding directions of the four diagonal slide rails correspond to each other. The four riveting sliders 43 can slide together and disperse along the diagonal slide rails.

In this embodiment, the specific distance and pressure magnitude of the stamping stroke can be set on the control panel to ensure the consistency of the riveting of the riveting ring of each optical fiber connector, complete high-precision automated riveting, and the foot control switch is used as a start switch.

[0031] As Figure 5As shown, in this embodiment, the optical fiber 6 includes many layers from the outside to the inside. The innermost layer is the optical fiber 61, and the outermost layer is the outer sheath layer. Inside the outer sheath layer is the aramid yarn layer, also called the Kevlar wire 62 layer. The Kevlar wire 62 layer is used to provide tensile strength for the optical fiber 6 and protect the innermost optical fiber. When the optical fiber connector is riveted, in fact, the riveting ring 51 of the optical fiber connector 5 and the Kevlar wire 62 layer are laminated together, and then the ferrule 52 of the optical fiber connector is sleeved on the riveting ring. In this embodiment, the four-way closing and pressing of the Kevlar wire of the optical fiber and the riveting ring by the riveting groove from four directions towards the middle can ensure better roundness of the riveting ring after riveting and more stable connection with the ferrule 52. The embossed pattern in the riveting groove can enhance the friction between the riveting ring and the Kevlar wire 62 layer after riveting, and also enhance the friction between the riveting ring and the ferrule, greatly improving the connection quality of the optical fiber connector.

The driving mechanism can drive the upper riveting module to press down, and then drive the four riveting sliders to slide along the inclined rails when the riveting groove touches the riveting ring, so as to drive the riveting block and the riveting groove to close and press the Kevlar wire of the optical fiber and the riveting ring from four directions towards the middle. Among them, the control mechanism can adjust and control the specific distance and pressure of the stamping stroke to complete high-precision automatic riveting. The size consistency of the riveting ring after riveting is good, and the quality stability of the product after riveting is good. The four-way closing and pressing of the Kevlar wire of the optical fiber and the riveting ring by the riveting groove from four directions towards the middle can ensure better roundness of the riveting ring after riveting and more stable connection with the ferrule. The embossed pattern in the riveting groove can enhance the friction between the riveting ring and the Kevlar wire after riveting, and also enhance the friction between the riveting ring and the ferrule, greatly improving the connection quality of the optical fiber connector, and solving the problems of unstable stamping stroke, unstable connection quality between the riveting ring and the Kevlar wire after riveting, and unstable connection quality between the riveting ring and the ferrule after riveting of the pneumatic up-and-down opening and closing riveting machine or the manual up-and-down opening and closing riveting machine on the current market.
