Description

Technical Field

[0001] This invention relates to the field of optical cable technology, and more particularly to a device for installing an optical cable reinforcing core. Background Technology

[0002] Currently, optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a protective sheath as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers, plastic protective tubes, and plastic outer sheaths. They generally contain steel wires, aluminum ribbons, and steel tapes, and generally have no recycling value. An optical cable is a communication line that uses a certain number of optical fibers arranged in a certain way to form a cable core, which is covered with a sheath, and some also have an outer protective layer, to realize the transmission of optical signals. Fiber optic connectors are widely used in FTTH broadband networks and 4G and 5G mobile networks. However, the manufacturing process of fiber optic connectors is relatively complex, especially the fixing process between the cable reinforcement core and the fiber optic connector, which directly affects the mechanical reliability of the fiber optic connector. The traditional radial crimping process has a relatively small holding force of about 100N between the cable reinforcement core and the fiber optic connector, but fiber optic connectors used outdoors require a more severe mechanical tensile force of more than 200N.

[0003] To address this, we designed a device for installing the reinforcing core of optical cables. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of improving the holding force between optical cables and optical fiber connectors, so that optical fiber connectors can be used outdoors and in scenarios requiring high mechanical tensile force. This invention proposes a device for installing optical cable reinforcing cores.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 1. A device for installing an optical cable reinforcing core, comprising a housing, an optical cable for auxiliary connection provided on the top of the housing, a fixing crimping ring for clamping and fixing the optical cable on the top of the housing, a connector body for connecting with the optical cable on the top of the housing, an optical cable fixing device for fixing and limiting displacement on one side of the optical cable, an optical fiber connector fixing device on the top of the housing, the optical fiber connector fixing device being fixedly installed on the top of the housing, an optical cable reinforcing core feature within the optical fiber connector fixing device, an optical cable traction mechanism for pulling the optical cable on one side of the optical cable, a traction connecting plate and a traction connecting rod on the top of the housing, the optical cable traction mechanism pulling the fixing crimping ring onto the optical fiber connector body via the traction connecting plate and the traction connecting rod, two fixing pressure plates on the top of the housing to prevent axial displacement of the optical cable during the operation of the optical cable traction mechanism, and the optical fiber connector body being fixedly installed on the top of the housing.

[0007] Preferably, the reinforcing core of the optical cable is made of steel wire, and the reinforcing core is fixedly installed in the optical fiber connector fixing device. The optical cable is evenly distributed in the reinforcing core features within the optical fiber connector fixing device.

[0008] Preferably, the top of the enclosure is provided with an optical cable fixing device, which is fixedly installed on the top of the enclosure. A first auxiliary cylinder and a first control module are provided on one side of the optical cable fixing device. The first auxiliary cylinder is fixedly installed on the top of the enclosure and is set close to the optical cable fixing device. The output end of the first auxiliary cylinder is connected to the first control module. Two fixing pressure plates are set on the top of the enclosure, and both fixing pressure plates are connected to the first control module.

[0009] Preferably, the top of the housing is provided with a second auxiliary cylinder and a second control module. The second auxiliary cylinder is fixedly installed on the top of the housing, and the output end of the second auxiliary cylinder is connected to the second control module.

[0010] Preferably, the top of the housing is provided with multiple mounting holes, which are adapted to the parts on the top.

[0011] Preferably, the box body has a first hole and a second hole symmetrically opened on both sides, and the first hole and the second hole are compatible with each other.

[0012] Preferably, the bottom of the box is provided with a base plate, and the top of the box is provided with a switch on one side.

The top of the housing is provided with a first fixing plate and a second fixing plate, and the optical cable traction mechanism and the second auxiliary cylinder are fixedly installed on the top of the housing through the first fixing plate and the second fixing plate, respectively.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention utilizes components such as an optical cable fixing device and a first auxiliary cylinder. The optical cable fixing device is equipped with a first auxiliary cylinder. By simply triggering the switches of the first and second auxiliary cylinders, the optical cable placed within can be fixed by the two fixing plates of the first auxiliary cylinder, keeping the optical cable stationary throughout the assembly process.

Detailed Implementation

[0022] Reference Figures 1-4A device for installing an optical cable reinforcing core includes a housing 100. The top of the housing 100 is provided with an optical cable 140 for auxiliary connection, used as a transmission medium for optical signal transmission. The top of the housing 100 is provided with a clamping crimp ring 150 for clamping and fixing the optical cable 140, providing auxiliary fixation during clamping and limiting. The top of the housing 100 is provided with a connector body 160 for connecting to the optical cable 140. A device 122 for adjusting the local dimensions of the optical fiber connector body allows for the use of various optical fiber connectors. One side of the optical cable 140 is provided with an optical cable fixing device 110 for fixing and limiting displacement of the optical cable 140, preventing axial displacement of the optical cable 140 when a traction device 130 is operating. One side of the optical cable 140 is provided with an optical cable traction mechanism 130 for traction, used when the cylinder 133 of the traction device 130 is triggered, the traction device 130 pulls the optical cable through a traction connecting plate 131. The traction connecting rod 132 pulls the fixing crimp ring 150 onto the fiber optic connector body 160, thereby achieving a firm connection between the optical cable 140 and the fiber optic connector body 160 through the fixing crimp ring 150. The top of the housing 100 is provided with two fixing pressure plates 111 to prevent the optical cable 140 from shifting along the optical cable axial direction when the optical cable traction mechanism 130 is working. The fixing pressure plates 111 are used to clamp the optical cable 140. The fiber optic connector body device 122 is fixedly installed on the top of the housing 100. It is used to adjust the local dimensions of the fiber optic connector body device 122. In addition to the design for placing the fiber optic connector body device 122, this device is also innovatively designed with a feature for placing the optical cable reinforcing core. This feature is a symmetrical structure. In addition to placing the optical cable reinforcing core, it can also evenly distribute the reinforcing core on both sides of the fiber optic connector, making the installation of the reinforcing core more reliable and the holding force between the optical cable 140 and the fiber optic connector greater. By adjusting the local dimensions of the fiber optic connector body 122, various fiber optic connectors can be universally used.

[0023] The reinforcing core of the optical cable 140 is made of steel wire. The top of the housing 100 is provided with an optical fiber connector fixing device 120, which is fixedly installed on the top of the housing 100 to assist in fixing the optical cable 140 at the top. The optical fiber connector fixing device 120 is provided with an optical cable reinforcing core feature 121, which is fixedly installed in the optical fiber connector fixing device 120 to enhance the fixing effect of the optical cable 140. The optical cables 140 are evenly distributed in the optical cable reinforcing core features 121 in the optical fiber connector fixing device 120, which are used to assist in positioning the optical cable 140.

[0024] The top of the enclosure 100 is equipped with a fiber optic cable fixing device 110 for auxiliary fixing of the fiber optic cable 140. The fiber optic cable fixing device 110 is fixedly installed on the top of the enclosure 100 for securing the fiber optic cable 140. A first auxiliary cylinder 112 and a first control module are located on one side of the fiber optic cable fixing device 110. The first auxiliary cylinder 112 is fixedly installed on the top of the enclosure 100 for driving and fixing the fiber optic cable 140 at the top of the enclosure. The first auxiliary cylinder 112 is positioned close to the fiber optic cable fixing device 110, and its output is connected to the first control module for controlling the fiber optic cable 140. The control module controls the process. Two fixed pressure plates 111 are set on the top of the housing 100. Both fixed pressure plates 111 are connected to the first control module. Through the optical cable fixing device 110 and the first auxiliary cylinder 112, etc., the optical cable fixing device 110 is equipped with the first auxiliary cylinder device 112. By simply triggering the switch of the first auxiliary cylinder 112 and the second auxiliary cylinder 133, the optical cable 140 placed inside can be fixed by the two fixed pressure plates 111 of the first auxiliary cylinder 112, so that the optical cable 140 remains stationary throughout the assembly process. This ensures that the optical fiber of the optical cable 140 will not bend or break, and avoids the optical fiber of the optical cable 140 from displacing along the optical cable axis during the assembly process.

[0025] The top of the housing 100 is provided with a second auxiliary cylinder 133 and a second control module. The second auxiliary cylinder 133 is fixedly installed on the top of the housing 100 and is used to assist in fixing and driving the optical cable 140 on the top of the housing 100. The output end of the second auxiliary cylinder 133 is connected to the second control module and is used to drive the second control module through the output end of the second auxiliary cylinder 133. The top of the housing 100 is provided with a traction connecting plate 131 and a traction connecting rod 132. The optical cable traction mechanism 130 pulls the fixing crimping ring 150 onto the optical fiber connector body 160 through the traction connecting plate 131 and the traction connecting rod 132, thereby realizing the firm connection between the optical cable 140 and the optical fiber connector body 160 through the fixing crimping ring 150.

[0026] The top of the housing 100 is provided with multiple mounting holes 190, which are adapted to the parts on the top. When installing and fixing the parts on the top of the housing 100, the multiple mounting holes 190 on the top of the housing 100 are used to assist in the installation, so as to facilitate the user's use of the whole device.

[0027] The housing 100 has a first hole 180 and a second hole 200 symmetrically opened on both sides. The first hole 180 and the second hole 200 are adapted to each other and are used to assist in fixing the optical cable 140 through the overall device, thereby reducing the weight of the overall device and avoiding the device being too heavy and thus inconvenient to use.

[0028] The bottom of the housing 100 is provided with a base plate 170 for closing the entire device. The top of the housing 100 is provided with a switch on one side. The switch is fixedly installed on one side of the first auxiliary cylinder 112 and the second auxiliary cylinder 133 for circuit control of the first auxiliary cylinder 112 and the second auxiliary cylinder 133. The switch is interconnected with the first auxiliary cylinder 112 and the second auxiliary cylinder 133. The first auxiliary cylinder 112 and the second auxiliary cylinder 133 are connected in series in the circuit, so that the first auxiliary cylinder 112 and the second auxiliary cylinder 133 can be controlled together by a single switch.

[0029] After the switch is turned on, the first auxiliary cylinder 112 and the second auxiliary cylinder 133 are activated sequentially. The switching delay of the first auxiliary cylinder 112 and the second auxiliary cylinder 133 is one second. The switching logic of the two cylinders is that the first auxiliary cylinder 112 is triggered first, and the second auxiliary cylinder 133 is triggered approximately one second later, so that one switch controls two cylinders. The top of the housing 100 is provided with a first fixing plate 134 and a second fixing plate 135. The optical cable pulling mechanism 130 and the second auxiliary cylinder 133 are fixedly mounted on the top of the housing 100 through the first fixing plate 134 and the second fixing plate 135, respectively, so as to fix the optical cable pulling mechanism 130 and the second auxiliary cylinder 133 to the top of the housing 100 through the first fixing plate 134 and the second fixing plate 135, thereby achieving the effect of assisting the optical cable 140.

[0030] The working principle of this invention is as follows: The optical cable 140, the fixing crimping ring 150, and the connector body 160 are placed on the housing 100. The optical cable is fixed by the first auxiliary cylinder 112 and the fixing pressure plate 111 of the optical cable fixing device 110, preventing the optical cable 140 from shifting axially when the optical cable traction mechanism 130 is working. The fixing crimping ring 150 is pre-inserted into the optical cable 140. The reinforcing core of the optical cable 140 is made of steel wire, and the reinforcing core is evenly distributed within the symmetrical features of the optical fiber connector fixing device 120. When the second auxiliary cylinder 13 of the optical cable traction mechanism 130 is triggered... After step 3, the optical cable pulling mechanism 130 pulls the fixed crimping ring 150 onto the optical fiber connector body 160 through the pulling connecting plate 131 and the pulling connecting rod 132, thereby realizing the firm connection between the optical cable 140 and the optical fiber connector body 160 through the fixed crimping ring 150. In the design of the second auxiliary cylinder 133 switch of the optical cable pulling mechanism 130, the present invention also integrates the switch of the first auxiliary cylinder of the optical cable fixing device 110. The switching logic of the two cylinders is that the first auxiliary cylinder is triggered first, and the second auxiliary cylinder 133 is triggered about 1 second later, realizing one switch controlling two cylinders.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
