Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector for optical fiber communication. Background Art

[0002] A fiber optic communication connector is a flexible joint that can connect two optical fibers or optical cables to form an optical path and can be repeatedly assembled and disassembled. It is often used to connect light sources and optical fibers, optical fibers and optical fibers, and optical fibers and detectors. Existing connectors are prone to loosening after multiple plugging and unplugging, affecting normal signal transmission.

[0003] Application No. 202220695050.6 discloses a connector for optical fiber communication, including a connecting shell, a connecting head, a fixing block, a conductive plate and a telescopic structure, etc. Through the action of the reset structure, during use, when the connecting shell needs to be installed and fixed, the user can press the pressing plate so that the pressing plate presses the movable plate downward, and the upper clamping sleeve presses the reset spring downward to shrink, thereby reducing the distance between the connecting shell and the movable plate, so that the connector can be connected more conveniently, and at the same time, the movable plate can be pushed upward by the action of the reset spring, thereby completing the clamping effect, and the effect of use is good. Through the action of the telescopic structure, when installing and connecting, the user can push the connecting shell to one side of the connecting head, and the movable spring will shrink, so that the connecting head can contact with the conductive head, thereby achieving the effect of mutual conduction between the conductive head and the connecting head, and the conductive head can be made conductive through the action of the movable spring, and at the same time, the movement of the conductive plate in the slide groove can be accommodated by the slide groove, and the effect of use is good. By clamping the conductive plate in the slide groove, the movable spring shrinks, and then the conductive head and the connecting head are contacted to complete the process of power-on, which can form a buffer at the connector head, and the effect of use is good.

[0004] However, in use, there are the following defects:

[0005] Although the contraction of the movable spring is used to buffer the conductive head and the connector to increase the service life of the connection and avoid poor contact, the optical fiber behind the connector may be pulled during the plugging and unplugging process. Especially when the connection position is difficult to separate due to dust accumulation and aging of parts, non-professionals may directly pull the optical fiber during operation, thereby damaging the optical fiber and affecting signal transmission. Utility Model Content

[0006] The purpose of the present application is to provide a connector for optical fiber communication, which solves the problem proposed in the background art that although the contraction of a movable spring is used to buffer the conductive head and the connector so that the service life of the connection can be increased to avoid poor contact, the optical fiber behind the connector may be pulled during the plugging and unplugging process, especially when the connection position is difficult to separate due to dust accumulation and aging of parts, non-professionals may directly pull the optical fiber during operation, thereby damaging the optical fiber and affecting signal transmission.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a connector for optical fiber communication, comprising a connector, a shell, a movable block, a storage groove and an inlet sleeve, the right side of the connector is fixedly connected and communicated with the shell, the right end of the shell is movably inserted and connected with the movable block, the right end of the movable block is fixedly connected with the storage groove, the right end of the storage groove is movably sleeved and connected with the inlet sleeve, a sliding groove is provided on the right side of the inner top and inner bottom of the storage groove, a slider is connected to the inner side of the sliding groove for transverse sliding, the slider is fixedly connected to the upper and lower ends of a fixed plate, and the upper and lower sides of the right wall of the fixed plate are fixedly connected to the left end of a No. 1 spring, the right end of the No. 1 spring is fixedly connected to the inner right side wall of the storage groove, and a sleeve pipe is fixedly connected to the inner top of the storage groove on the left side of the fixed plate.

[0008] In this technical solution, by inserting the movable block into the shell, the conductive head contacts the conductive sheet in the connector to complete the signal connection and transmission. In this process, the No. 3 spring can buffer the movable block to prevent the conductive head from being inserted with too much force and damaging the conductive sheet. During the insertion of the movable block, the plug-in block on its side wall will also be inserted into the slot on the side wall of the shell. When inserted, the plug-in block will squeeze the extrusion block into the extrusion groove. After entering, the extrusion block bounces back to complete the fixation of the plug-in block. When the plug-in block needs to be removed, it is only necessary to pull the pull rod to pull the extrusion block back into the extrusion groove. The optical fiber line can be protected and buffered by the fixed plate, No. 1 spring, slide groove and slider. When the device is pulled out, the optical fiber line may be stretched. At this time, the slide groove drives the fixed plate to slide to the right in the storage groove, driving the storage The optical fiber line in the groove moves to the right. Since the length of the optical fiber line is reserved in the storage groove, damage to the optical fiber line can be avoided when it is stretched, and the No. 1 spring can squeeze the fixing plate back to its original position after the stretching is completed, thereby improving the protection ability and practicality of the device. At the same time, the limit block, the telescopic block, the No. 2 spring and the sleeve tube can prevent the optical fiber line from being folded to a large extent. The limit block usually limits the optical fiber line to the bottom of the storage groove. When the optical fiber line is stretched, the limit block moves upward. At this time, the telescopic block moves into the sleeve tube. After the stretching is completed, the limit block can limit the optical fiber line to the bottom of the storage groove again, preventing the reserved length of the optical fiber line from changing direction and shifting when retracted, avoiding excessive folding that may affect signal transmission, and improving the practicality and stability of the device.

[0009] As an optional solution of the technical solution of the present application, a No. 2 spring is fixedly installed on the inner side of the sleeve, the bottom of the No. 2 spring is fixedly connected to the top of the telescopic block, and the telescopic block is vertically slidably connected to the inner side of the sleeve, and the bottom of the telescopic block is fixedly connected to the limiting block.

[0010] As an optional solution of the technical solution of the present application, a conductive head is fixedly installed on the left end of the movable block, and the left ends of the movable block on the upper and lower sides of the conductive head are fixedly connected to the right end of the No. 3 spring, and the left end of the No. 3 spring is fixedly connected to the inner left side wall of the outer shell.

[0011] As an optional solution of the technical solution of the present application, a conductive sheet is fixedly installed in the center of the interior of the connector.

[0012] As an optional solution of the technical solution of the present application, an optical fiber line is opened on the inner side of the line inlet sleeve, the center of the side wall of the fixed plate is fixedly connected to the optical fiber line, and the left end of the optical fiber line passes through the left side wall of the storage groove and the movable block and is fixedly connected to the conductive head.

[0013] As an optional scheme of the technical scheme of the present application, a slot is fixedly installed on the side wall of the shell close to the movable block, and an insert block is fixedly installed on the side wall of the movable block. Extrusion grooves are opened on the upper and lower sides of the interior of the slot, and a pull rod passes through the side wall of the slot outside the extrusion groove. The end of the pull rod located on the inner side of the slot is fixedly connected to the extrusion block, and the extrusion block is vertically slidably connected on the inner side of the extrusion groove, and the pull rod is movably sleeved on the surface of the side wall inside the slot and is connected to an extrusion spring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can protect and buffer the optical fiber line through the fixed plate, No. 1 spring, sliding groove and sliding block. When the device is pulled out, the optical fiber line may be stretched. At this time, the sliding groove drives the fixed plate to slide to the right in the storage groove, driving the optical fiber line in the storage groove to move right. Since the length of the optical fiber line is reserved in the storage groove, damage to the optical fiber line can be avoided during stretching, and the No. 1 spring can squeeze the fixed plate back to its original position after the stretching is completed, thereby improving the protection ability and practicality of the device.

[0016] 2. The present application uses a limit block, a telescopic block, a No. 2 spring and a sleeve tube to prevent the optical fiber line from being folded significantly. The limit block will normally limit the optical fiber line to the bottom of the storage slot. When the optical fiber line is stretched, the limit block will move upward, and the telescopic block will move toward the sleeve tube. After the stretching is completed, the limit block can re-limit the optical fiber line to the bottom of the storage slot to prevent the reserved length of the optical fiber line from changing direction and shifting when retracted, thereby avoiding excessive folding that may affect signal transmission and improving the practicality and stability of the device.

[0025] like Figure 2 and Figure 3 As shown, a slide groove 9 is opened on the right side of the inner top and inner bottom of the storage groove 4, and a slider 701 is connected to the inner side of the slide groove 9 for transverse sliding. The slider 701 is fixedly connected to the upper and lower ends of the fixed plate 7, and the upper and lower sides of the right wall of the fixed plate 7 are fixedly connected to the left end of the No. 1 spring 8, and the right end of the No. 1 spring 8 is fixedly connected to the inner right side wall of the storage groove 4. The fixed plate 7 is fixedly connected to the optical fiber line 6, and can drive the optical fiber line 6 to move together during the sliding process.

[0026] like Figure 3 As shown, a sleeve tube 102 is fixedly connected to the top of the storage slot 4 on the left side of the fixed plate 7, and a No. 2 spring 101 is fixedly installed on the inner side of the sleeve tube 102. The bottom of the No. 2 spring 101 is fixedly connected to the top of the telescopic block 10, and the telescopic block 10 is vertically slidably connected on the inner side of the sleeve tube 102. The bottom of the telescopic block 10 is fixedly connected to a limit block 11, and the limit block 11 can limit the optical fiber line 6 at the bottom of the storage slot 4 to prevent displacement and folding.

[0027] like Figure 3 As shown, a conductive head 12 is fixedly installed on the left end of the movable block 3, and the left ends of the movable block 3 on the upper and lower sides of the conductive head 12 are fixedly connected to the right end of the No. 3 spring 14, the left end of the No. 3 spring 14 is fixedly connected to the inner left side wall of the outer shell 2, and a conductive sheet 13 is fixedly installed in the inner center of the connector 1.

[0028] like Figure 3 As shown, an optical fiber line 6 is opened on the inner side of the line inlet sleeve 5, the center of the side wall of the fixing plate 7 is fixedly connected to the optical fiber line 6, and the left end of the optical fiber line 6 passes through the left side wall of the storage groove 4 and the movable block 3 and is fixedly connected to the conductive head 12.

[0029] like Figure 4 As shown, extrusion grooves 15 are opened on the upper and lower sides of the interior of the slot 201, and a pull rod 16 passes through the side wall of the slot 201 outside the extrusion groove 15, and one end of the pull rod 16 located on the inner side of the slot 201 is fixedly connected with an extrusion block 17, and the extrusion block 17 is vertically slidably connected on the inner side of the extrusion groove 15, and the pull rod 16 is located on the side wall surface inside the slot 201 and is movably connected with an extrusion spring 18.
