Description

Technical Field

[0001] This utility model relates to the field of optical cable connector technology, and more specifically to a pre-fabricated end-shaped optical cable connector. Background Technology

[0002] The butterfly-shaped optical cable is a new type of user access optical cable. Based on different application environments and laying conditions, the optical cable structure and various technical parameters are rationally designed. It combines the characteristics of indoor flexible optical cables and self-supporting optical cables. It is produced using special equipment and imported precision molds, and plays a unique role in building intelligent buildings, digital communities, campus networks, local area networks and other networks.

[0003] When laying butterfly-shaped optical cables, connectors need to be installed at the ends to connect to the optical modem. Cold-splitter fiber optic connectors are a common type of optical cable connector, which typically consists of an outer sheath, a cold-splitter, a ferrule, a fiber optic crimp cap, and a tail cap. In use, the tail cap must be removed first, then the optical cable must be passed through the tail cap, then the fiber optic crimp cap must be opened, then the fiber optic cable must be inserted into the ferrule, then the fiber optic crimp cap must be closed, and finally the tail cap must be reinstalled. The overall operation is quite cumbersome. Therefore, there is an urgent need to design a pre-terminated butterfly-shaped optical cable connector to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pre-formed end-wound butterfly optical cable connector to solve the problem of cumbersome use steps of the existing cold-splitting optical fiber connectors in the background art.

[0005] This utility model provides the following technical solution: a pre-fabricated end-butterfly-shaped optical cable connector, including an outer sheath, a cold connector, a ferrule, and also a fixing plate, a clamping assembly, and a locking assembly. The cold connector is disposed inside the outer sheath, the ferrule is disposed inside the cold connector, the fixing plate is fixedly installed at one end of the cold connector, the clamping assembly is disposed on the top of the fixing plate, and the locking assembly is disposed inside the clamping assembly. The locking assembly can be connected to the fixing plate.

[0006] The clamping assembly includes a clamping plate, which is located on top of the fixed plate. The locking assembly includes two C-shaped rods and four insert rods. The two C-shaped rods are slidably installed inside the clamping plate, and the four insert rods are fixedly installed at the ends of the two C-shaped rods that are far apart from each other. The insert rods are slidably inserted into the fixed plate.

[0007] Furthermore, the top of the fixing plate and the bottom of the clamping plate are both provided with fiber core grooves and fiber grooves.

[0008] Furthermore, four through slots are provided between the top and bottom of the clamping plate, and the C-shaped rod is slidably installed between two through slots. The top of the fixing plate is provided with four strip slots, which are adapted to the C-shaped rods. A slot is provided on the inner wall of one end of the strip slot, which is adapted to the insertion rod.

[0009] Furthermore, the locking assembly also includes two sliders and a spring. The two sliders are fixedly installed at the bottom of the two C-shaped rods, and the spring is fixedly installed between the two sliders. A groove is provided on the top of the clamping plate, and both sliders are slidably installed in the groove.

[0010] Furthermore, the clamping assembly also includes a fixing rod, which is fixedly installed in the slide groove, and both sliders are slidably sleeved on the outer wall of the fixing rod.

[0011] Furthermore, the clamping assembly also includes a support frame, which is fixedly installed on the bottom of the clamping plate. Grooves are provided between the two sides and the bottom of the fixed plate, and the support frame is slidably installed in the grooves.

[0012] Furthermore, several rubber strips are provided at both ends of the support frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention, through its fixed plate, clamping assembly, and locking assembly, allows users to unlock the clamping plate by simply pinching the two C-shaped rods during optical cable installation. Then, the clamping plate is slid upwards, and the support frame is pushed into the groove. The friction between the rubber strip and the groove temporarily fixes the support frame and the clamping plate. After the optical cable is plugged in, the installation is completed by simply pressing the clamping plate, simplifying the operation steps and improving convenience. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 5 The present invention will be further described below.

[0023] A pre-terminated butterfly-shaped optical cable connector includes an outer sheath 1, a cold connector 2, and a ferrule 6. It also includes a fixing plate 3, a clamping assembly 4, and a locking assembly 5. The cold connector 2 is disposed inside the outer sheath 1, the ferrule 6 is disposed inside the cold connector 2, the fixing plate 3 is fixedly installed at one end of the cold connector 2, the clamping assembly 4 is disposed on the top of the fixing plate 3, and the locking assembly 5 is disposed inside the clamping assembly 4. The locking assembly 5 can be connected to the fixing plate 3.

[0024] The clamping assembly 4 includes a clamping plate 401, which is disposed on the top of the fixed plate 3. The locking assembly 5 includes two C-shaped rods 501 and four insert rods 502. The two C-shaped rods 501 are slidably installed in the clamping plate 401, and the four insert rods 502 are respectively fixedly installed at the ends of the two C-shaped rods 501 that are far apart from each other. The insert rods 502 are slidably inserted into the fixed plate 3.

[0025] Specifically, fiber core grooves 7 and fiber grooves 8 are provided on the top of the fixing plate 3 and the bottom of the clamping plate 401.

[0026] Specifically, four through slots 403 are provided between the top and bottom of the clamping plate 401, and the C-shaped rod 501 is slidably installed between two through slots 403. The top of the fixing plate 3 is provided with four strip slots 9, which are adapted to the C-shaped rod 501. A slot 11 is provided on the inner wall of one end of the strip slot 9, which is adapted to the insertion rod 502.

[0027] Specifically, the locking assembly 5 also includes two sliders 503 and a spring 504. The two sliders 503 are fixedly installed at the bottom of the two C-shaped rods 501 respectively, and the spring 504 is fixedly installed between the two sliders 503. The top of the clamping plate 401 is provided with a slide groove 402, and the two sliders 503 are slidably installed in the slide groove 402.

[0028] In this embodiment, in the initial state, the spring 504 is in the released state and pushes the two C-shaped rods 501 away from each other.

[0029] Specifically, the clamping assembly 4 also includes a fixing rod 404, which is fixedly installed in the slide groove 402, and the two sliders 503 are slidably sleeved on the outer wall of the fixing rod 404.

[0030] In this embodiment, the fixed rod 404 can limit the two sliders 503 and the two C-shaped rods 501 to prevent them from detaching from the sliding plate 401.

[0031] Specifically, the clamping assembly 4 also includes a support frame 405, which is fixedly installed on the bottom of the clamping plate 401. A groove 10 is provided between the two sides and the bottom of the fixed plate 3, and the support frame 405 is slidably installed in the groove 10.

[0032] Specifically, several rubber strips 406 are provided at both ends of the support frame 405.

[0033] Working principle: During use, pinching the two C-shaped rods 501 will disengage the four insertion rods 502 from the slot 11, thus unlocking the clamping plate 401. Sliding the clamping plate 401 upwards will cause the support frame 405 to slide within the groove 10. Pressing the support frame 405 into the groove 10 allows the friction between the rubber strip 406 and the groove 10 to temporarily fix the support frame 405 and the clamping plate 401. Then, insert the optical fiber into the ferrule 6. After insertion, simply press the clamping plate 401. Since one end of the insertion rod 502 is inclined, when the four insertion rods 502 touch the edge of the strip groove 9 during the downward movement, they will be squeezed and move closer to each other, thereby causing the two C-shaped rods 501 and the two sliders 503 to move closer to each other. At this time, the spring 504 will be compressed. When the insertion rod 502 slides down to correspond to the slot 11, the spring 504 will be released and push the two C-shaped rods 501 away from each other, thereby causing the four insertion rods 502 to be inserted into the slot 11 and locking the clamping plate 401.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
