Description

Technical Field

[0001] This utility model belongs to the field of optical fiber connector technology, and in particular relates to a closed optical fiber connector plug. Background Technology

[0002] As a key component for enabling detachable connections between optical fibers, fiber optic connectors play a crucial role in optical communication systems. They enable precise alignment of the end faces of two optical fibers to achieve efficient transmission of optical energy and minimize the impact on the performance of the optical link system.

[0003] However, existing enclosed fiber optic connector plugs have revealed some obvious defects in actual use. In terms of connection, after the plug and socket are connected, there is a lack of effective reinforcement structure. During daily use, once subjected to external forces, such as cable pulling or equipment vibration, the plug is very prone to loosening. This not only leads to interruption of optical signal transmission and affects communication quality, but frequent loosening of the connection may also cause wear and tear on the plug and socket, shortening their service life. In addition, the sealing at the gaps of the connector is not good. In dusty environments, dust can easily seep into the inside of the connector through the gaps. The accumulation of dust may affect the cleanliness of the fiber end face, thereby increasing the attenuation of the optical signal and reducing the transmission efficiency.

[0004] To address these issues, we provide a sealed fiber optic connector plug. Utility Model Content

[0005] The purpose of this utility model is to provide a closed fiber optic connector plug. Through the cooperation of the sealing groove, sealing shell and reinforcement components, it solves the problem that the existing fiber optic connector plugs lack an effective reinforcement structure. During daily use, once subjected to external forces, such as cable pulling or equipment vibration, the plug is very likely to loosen.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a closed-type fiber optic connector plug, comprising a male connector plate and a female connector plate. A first connector head is fixedly connected to one side of the male connector plate, and a connector shell is fixedly connected to one side of the female connector plate. A second connector head is disposed within the inner cavity of the connector shell. A core rod is fixedly connected to one side of the first connector head, and a core groove is formed on one side of the second connector head. A reinforcing assembly is disposed on the top of the connector shell. The reinforcing assembly includes a fixing plate, one side of which is fixedly connected to the surface of the female connector plate. A slot is formed on one side of the fixing plate. A pin is passed through the top of the fixing plate. A rotating clamping plate is fixedly connected to the top of the pin. A clamping frame is fixedly connected to one side of the top of the fixing plate. A plug plate is fixedly connected to the top of one side of the male connector plate, and a slot is formed on the top of the plug plate.

[0008] The present invention is further configured such that a tail sleeve is fixedly connected to the opposite side of the male connector plate and the female connector plate, and a protective sleeve is fixedly connected to one side of the tail sleeve. One end of the optical fiber is inserted into the inner cavity of the tail sleeve and connected to the first connector and the second connector. The protective sleeve at the tail of the tail sleeve can protect the connection between the optical fiber and the tail sleeve.

[0009] The present invention is further provided that anti-slip pads are fixedly connected to the front and back of the male and female connector boards. The anti-slip pads are provided with anti-slip textures on their surfaces. The anti-slip pads with anti-slip textures can improve the anti-slip properties of the male and female connector boards, making it easier for fiber optic installation personnel to operate the connector plugs.

[0010] The present invention is further configured such that a sealing groove is provided on one side of the male connector plate, and a sealing shell is fixedly connected to one side of the female connector plate. The sealing shell is inserted into the inner cavity of the sealing groove as the male connector plate and the female connector plate approach each other. The sealing structure formed by the sealing shell and the sealing groove seals the connection between the male connector plate and the female connector plate, preventing dust from seeping in.

[0011] The present invention is further configured such that a locking plate is fixedly connected to one side of the inner cavity of the slot, and a locking groove is provided on one side of the insert plate. As the insert plate is inserted into the inner cavity of the slot, the locking plate on one side of the inner cavity of the slot is inserted into the inner cavity of the locking groove on the surface of the insert plate. The limiting structure formed by the locking plate and the locking groove improves the stability of the insert plate inserted into the slot.

[0012] The present invention is further configured such that a magnetic block is fixedly connected to one side of the inner cavity of the slot, and one side of the magnetic block is in contact with the surface of the locking plate. As the insert plate is inserted into the inner cavity of the slot, the magnetic block attracts one side of the insert plate. Through the attraction and limiting effect of the magnetic block, the stability of the insert plate after being inserted into the slot is improved.

[0013] The present invention is further configured such that limiting plates are fixedly connected to the top and bottom of the inner cavity of the plug-in shell. The limiting plates are located above and below the second connector, respectively. After the first connector is inserted into the inner cavity of the plug-in shell, the limiting plate will abut against one side of the first connector to limit the movement range of the first connector, thereby avoiding damage to the first and second connectors due to long-term insertion and removal and improper force control.

[0014] The present invention is further configured such that a sloping dustproof plate is fixedly connected to one side of the fixing plate. The sloping dustproof plate is made of synthetic rubber. As the insert plate is inserted into the inner cavity of the slot, the sloping dustproof plate adheres tightly to the surface of the insert plate, which can prevent a large amount of external dust and water stains from seeping into the inner cavity of the slot and affecting the subsequent use of the reinforcement component.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model ensures the stability of the connection through a multi-interlocking and locking structure. During the connection process, the initial positioning of the first connector and the plug shell, and the precise docking of the core rod and the core groove form a core fit. At the same time, the insertion of the plug plate and the slot further enhances the fit of the structure. Subsequently, the double locking design of the pin being inserted into the slot and the rotating clamping plate being inserted into the clamping frame can effectively prevent the male plug plate and the female plug plate from loosening or separating, ensuring a stable connection during use.

[0017] 2. When the male and female connectors are connected, the sealing shell and the sealing groove are precisely fitted to form a closed structure, which directly seals the connection between the male and female connectors in all directions. This effectively prevents dust and other impurities from penetrating into the internal core components. This sealing function, which is achieved simultaneously with the connection, can not only prevent impurities from affecting the optical fiber transmission performance, but also extend the service life of the connector.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a closed fiber optic connector plug, including a male connector plate 1 and a female connector plate 2. A first connector 3 is fixedly connected to one side of the male connector plate 1, and a connector shell 4 is fixedly connected to one side of the female connector plate 2. A second connector 5 is provided in the inner cavity of the connector shell 4. A core rod 6 is fixedly connected to one side of the first connector 3, and a core groove 7 is opened on one side of the second connector 5. A reinforcing component 8 is provided on the top of the connector shell 4. The reinforcing component 8 includes a fixing plate 801. One side of the fixing plate 801 is fixedly connected to the surface of the female connector plate 2. A slot 802 is opened on one side of the fixing plate 801. A pin 803 is passed through the top of the fixing plate 801. A rotating clamping plate 804 is fixedly connected to the top of the pin 803. A clamping frame 805 is fixedly connected to one side of the top of the fixing plate 801. A plug plate 806 is fixedly connected to the top of one side of the male connector plate 1. A slot 807 is opened on the top of the plug plate 806.

[0028] Specifically: the male connector 1 is moved to insert the first connector 3 on one side into the connector shell 4 on the side of the female connector 2. As the male connector 1 and the female connector 2 continue to approach each other, the core rod 6 on the side of the first connector 3 will be inserted into the core groove 7 on the side of the second connector 5. At the same time, the plug 806 is inserted into the slot 802 on the side of the fixing plate 801. The pin 803 is moved to its bottom and inserted into the slot 807 on the surface of the plug 806. The rotating clamping plate 804 at one end of the pin 803 is rotated to its side and locked into the inner cavity of the clamping frame 805, thereby completing the connection of the fiber optic connector plug.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, tail sleeves 9 are fixedly connected to opposite sides of male connector plate 1 and female connector plate 2. A protective sleeve is fixedly connected to one side of tail sleeve 9. Anti-slip pads are fixedly connected to the front and back of male connector plate 1 and female connector plate 2. The surface of the anti-slip pads is provided with anti-slip texture. A sealing groove 10 is opened on one side of male connector plate 1. A sealing shell 11 is fixedly connected to one side of female connector plate 2. A locking plate is fixedly connected to one side of the inner cavity of slot 802. A locking groove is opened on one side of connector plate 806. A magnetic block is fixedly connected to one side of the inner cavity of slot 802. One side of the magnetic block is in contact with the surface of the locking plate. Limiting plates are fixedly connected to the top and bottom of the inner cavity of connector shell 4. The limiting plates are located above and below the second connector head 5, respectively. A sloping dustproof plate is fixedly connected to one side of fixing plate 801. The sloping dustproof plate is made of synthetic rubber.

[0031] Specifically: One end of the optical fiber is inserted into the inner cavity of the tail sleeve 9 and connected to the first connector 3 and the second connector 5. The protective sleeve at the tail of the tail sleeve 9 protects the connection between the optical fiber and the tail sleeve 9. The anti-slip pad with anti-slip texture on the surface can improve the anti-slip properties of the male connector plate 1 and the female connector plate 2, making it convenient for optical fiber installation personnel to operate the connector plug. The sealing shell 11 is inserted into the inner cavity of the sealing groove 10 as the male connector plate 1 and the female connector plate 2 approach each other. The sealing structure formed by the sealing shell 11 and the sealing groove 10 seals the connection between the male connector plate 1 and the female connector plate 2, preventing dust from seeping in. As the insert plate 806 is inserted into the inner cavity of the slot 802, the locking plate on one side of the inner cavity of the slot 802 is inserted into the locking groove inner cavity on the surface of the insert plate 806. The locking plate engages with the locking groove. The limiting structure formed by the slots improves the stability of the insert plate 806 when inserted into the slot 802. As the insert plate 806 is inserted into the inner cavity of the slot 802, the magnetic block attracts one side of the insert plate 806. Through the attraction and limiting effect of the magnetic block, the stability of the insert plate 806 after being inserted into the slot 802 is improved. After the first connector 3 is inserted into the inner cavity of the plug shell 4, the limiting plate will abut against one side of the first connector 3 to limit the movement range of the first connector 3, avoiding damage to the first connector 3 and the second connector 5 due to long-term insertion and removal and improper force control. As the insert plate 806 is inserted into the inner cavity of the slot 802, the inclined dustproof plate is close to the surface of the insert plate 806, which can prevent a large amount of external dust and water stains from seeping into the inner cavity of the slot 802 and affecting the subsequent use of the reinforcement component 8.

[0032] The working principle of this utility model is as follows: The male connector 1 is moved until its first connector 3 is inserted into the connector shell 4 on one side of the female connector 2. As the male connector 1 and female connector 2 continue to approach each other, the core rod 6 on one side of the first connector 3 is inserted into the core groove 7 on one side of the second connector 5. Simultaneously, the connector 806 is inserted into the slot 802 on one side of the fixing plate 801. The pin 803 is moved to its bottom and inserted into the slot 807 on the surface of the connector 806. The pin 803 is then rotated... The rotating clamping plate 804 at one end is inserted into the inner cavity of the clamping frame 805 on one side, connecting the male plug plate 1 and the female plug plate 2 together on one side. As the male plug plate 1 and the female plug plate 2 are connected, one side of the plug shell 4 abuts against the male plug plate 1. The sealing shell 11 on one side of the female plug plate 2 is inserted into the sealing groove 10 on one side of the male plug plate 1. The sealing structure composed of the sealing shell 11 and the sealing groove 10 seals the connection between the male plug plate 1 and the female plug plate 2, preventing dust from seeping in.
