Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector technology, and in particular to an MPO metal connector. Background Technology

[0002] MPO connectors, as a type of high-density multi-core fiber optic connector, play a crucial role in data centers, high-speed optical communication networks, and other fields. To adapt to more demanding industrial environments or meet high reliability requirements, MPO metal connectors are widely used due to their high mechanical strength, corrosion resistance, and good electromagnetic shielding performance.

[0003] In the structure of the MPO metal connector, the mounting head that carries and aligns the multi-core optical fiber is the core precision component. The cleanliness and alignment accuracy of the mounting head's end face directly affect the transmission quality of the optical signal. However, in actual use, due to frequent plugging and unplugging operations, dust pollution in the field environment, or accidental bumps, the mounting head or the internal optical fiber end face may be worn, contaminated, or damaged.

[0004] Currently, in the design of MPO metal connectors, the internal mounting head is integrated and fixed inside the metal connector plug, for example, by adhesive bonding, press fitting, or integrated encapsulation. Although this structure ensures initial stability, once the mounting head fails or is damaged, maintenance personnel cannot quickly disassemble and replace it on-site. This non-removable design means that when the delicate and fragile mounting head fails, the entire high-value metal connector plug must be discarded, resulting in a huge waste of maintenance costs and resources.

[0005] Therefore, this utility model proposes an MPO metal connector to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing MPO metal connector, such as the difficulty in disassembling and replacing the internal mounting head after damage, which leads to the scrapping of the entire connector and high maintenance costs, this utility model aims to provide an MPO metal connector with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an MPO metal connector, including: a metal shell, a metal connector plug, and a mounting head.

[0008] The metal connector is detachably threaded to the metal housing. The metal connector has an internal mounting groove and an external circular groove. The mounting head is pluggable into the mounting groove. The MPO metal connector also includes a disassembly mechanism located inside the metal connector. The disassembly mechanism includes a retaining ring, a slider, a spring, a limiting rod, and an arc-shaped elastic plate.

[0009] The retaining ring is fixed to the outer periphery of the mounting head; the slider is slidably mounted on the inner wall of the metal connector; a spring is located between the slider and the inner wall of the metal connector, and the spring is used to push the slider to return to its original position, so that the bottom end of the slider engages with the retaining ring; one end of the limiting rod is connected to the slider, and the rod body of the limiting rod passes through the wall of the metal connector and slides along the circular groove; the arc-shaped elastic plate is connected to the other end of the limiting rod.

[0010] Preferably, the slider has a beveled surface. This beveled structure allows the retaining ring to contact the beveled surface and press the slider outward when the mounting head is pressed down along the mounting groove, thereby achieving convenient press-locking.

[0011] Preferably, the top of the mounting head has a mounting hole, and the MPO metal connector also includes a limiting sleeve connected to the top of the mounting hole for guiding and initially positioning the inserted optical fiber.

[0012] Furthermore, the MPO metal connector also includes a fixing clip, which is elastically clamped to both sides of the outer wall of the limiting sleeve. The elastic clamping force provides a firm fixation to the limiting sleeve to prevent loosening or misalignment during use.

[0013] Preferably, an external threaded collar is installed on the outer side of the mounting head. The external threaded collar is an annular component located at the base of the mounting head and can be used for mating and connecting with other components.

[0014] Preferably, the top of the metal housing is fixed with an external threaded sleeve, and the MPO metal connector also includes a nut, which is threadedly connected to the external threaded sleeve. The combination of the external threaded sleeve and the nut is used to make a stable and reliable connection between the metal housing and external equipment.

[0015] Preferably, the outer surface of the metal connector is provided with anti-slip texture, which is a groove or raised structure surrounding the outer periphery of the metal connector, increasing the friction between the user's hand and the outer surface of the connector, making it easier to perform the twisting operation.

[0016] Preferably, the MPO metal connector further includes a pull cord, which is fixed to the tail of the metal connector plug. Especially in narrow spaces with high-density wiring, the pull cord provides users with a convenient point of force, making it easy to plug and unplug the metal connector plug.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the mounting head inside the metal connector plug is difficult to disassemble after damage, resulting in the entire plug being scrapped, by setting up a disassembly mechanism consisting of an arc-shaped elastic plate, a limiting rod, a slider, a spring, and a retaining ring.

[0018] 2. This utility model solves the problems of alignment difficulties or inconvenient locking that may exist during the installation of traditional plug-in structures by setting the slider to have an inclined surface structure and using the elastic force of the spring to push the slider to reset.

[0019] 3. This utility model solves the problem that multi-core optical fibers are prone to loosening or misalignment due to structural instability after being aligned in the mounting head by setting a limiting sleeve and a fixing clamp that elastically holds the fiber on both sides of the outer wall of the limiting sleeve.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example:

[0023] Please refer to Figures 1 to 4 This utility model provides an MPO metal connector, including a metal housing 1 and a metal connector plug 3 that is detachably threaded to the metal housing 1. The metal housing 1 is used to stably connect the entire connector to external equipment, and the metal connector plug 3 is used to accommodate fiber optic installation components and realize the detachable function.

[0024] The metal connector plug 3 has an internal mounting groove 201, and the mounting head 6 can be plugged into the mounting groove 201. The outer wall of the metal connector plug 3 also has a circular groove.

[0025] The MPO metal connector also includes a disassembly mechanism 2 disposed inside the metal connector plug 3. The disassembly mechanism 2 is used to lock and release the mounting head 6. The disassembly mechanism 2 includes a retaining ring 202, a slider 203, a spring 204, a limit rod 205, and an arc-shaped elastic plate 206.

[0026] Specifically, the retaining ring 202 is fixed to the outer periphery of the mounting head 6, the slider 203 is slidably mounted on the inner wall of the metal connector 3, and the spring 204 is located between the slider 203 and the inner wall of the metal connector 3. The spring 204 is used to push the slider 203 to return to its original position, so that the bottom end of the slider 203 engages with the retaining ring 202, thereby locking the mounting head 6.

[0027] One end of the limiting rod 205 is connected to the slider 203. The rod body of the limiting rod 205 passes through the wall of the metal connector plug 3 and slides along the circular groove. The arc-shaped elastic plate 206 is connected to the other end of the limiting rod 205. When the arc-shaped elastic plate 206 is pulled, the limiting rod 205 drives the slider 203 to slide outward and compress the spring 204, so that the bottom end of the slider 203 separates from the retaining ring 202, thereby making it easy to remove the mounting head 6.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 The slider 203 has an inclined surface. The inclined surface is designed so that when the mounting head 6 is pressed down along the mounting groove 201, the retaining ring 202 can first contact the inclined surface of the slider 203 and slide along the inclined surface. Under the action of the pressing force, the retaining ring 202 squeezes the slider 203 outward, realizing convenient press-type installation.

[0029] like Figure 3 As shown, the top of the mounting head 6 has a mounting hole 7 for aligning and connecting multi-core optical fibers. The MPO metal connector also includes a limiting sleeve 8, which is connected to the top of the mounting hole 7 and is used to guide the insertion of the optical fiber to ensure alignment accuracy. The MPO metal connector also includes a fixing clip 9, which is elastically clamped to both sides of the outer wall of the limiting sleeve 8. The fixing clip 9 fixes the limiting sleeve 8 with elastic clamping force and is used to prevent the limiting sleeve 8 from loosening and misaligning during use, ensuring the long-term stability of the optical fiber connection.

[0030] As a preferred embodiment, please refer to Figure 3 An external threaded collar 5 is installed on the outer side of the mounting head 6. The external threaded collar 5 is an annular component located at the base of the mounting head 6.

[0031] As another preferred embodiment, please refer to Figure 1 In order to securely fix the entire connector to the external device, an external threaded sleeve 10 is fixed to the top of the metal housing 1, and a nut 11 is threadedly connected to the external threaded sleeve 10. The external threaded sleeve 10 and the nut 11 are used to securely connect the metal housing 1 to the external device.

[0032] As another preferred embodiment, please refer to Figure 1 To facilitate the user in turning the metal connector plug 3, the outer surface of the metal connector plug 3 is provided with anti-slip texture 4. The anti-slip texture 4 is a groove or protrusion structure surrounding the outer periphery of the metal connector plug 3, which is used to increase the friction when turning.

[0033] As another preferred embodiment, please refer to Figure 1 To facilitate plugging and unplugging operations in confined spaces, the MPO metal connector also includes a pull cable 12, which is fixed to the tail of the metal connector plug 3 to facilitate plugging and unplugging operations.

[0034] Working principle: During fiber optic installation, first, the metal connector 3 is rotated away from the metal housing 1. At this time, the fiber optic cable is inserted into the mounting hole 7 at the top of the mounting head 6 through the groove in the limiting sleeve 8. The limiting sleeve 8 and the fixing clip 9 cooperate to guide and limit the fiber optic cable. The fixing clip 9 is elastically clamped on both sides of the outer wall of the limiting sleeve 8 to prevent the limiting sleeve 8 from loosening or misaligning during use. After the fiber optic cable is installed, the metal connector 3 is rotated so that the metal connector 3 is detachably threaded to the metal housing 1. The anti-slip texture 4 on the outer surface of the metal connector 3 is used to increase the friction during screwing. The external threaded sleeve 10 and the threaded nut 11 at the top of the metal housing 1 are used to stably connect the metal housing 1 to the external equipment. The pull cable 12 is fixed to the tail of the metal connector 3 to facilitate the user's plugging and unplugging of the metal connector 3. When the mounting head 6 needs to be disassembled and replaced, pull the arc-shaped elastic plate 206 of the disassembly mechanism 2. Because the arc-shaped elastic plate 206 is elastic, it will drive the rod of the limiting rod 205 to pass through the wall of the metal connector plug 3 and slide along the circular groove on the outer wall of the metal connector plug 3. At this time, the limiting rod 205 drives the slider 203 to slide outward. The slider 203 is slidably installed on the inner wall of the metal connector plug 3. When the slider 203 slides outward, it will compress the spring 204 provided between the slider 203 and the inner wall of the metal connector plug 3. After the slider 203 moves outward, the bottom end is no longer locked to the retaining ring 202 on the outer periphery of the mounting head 6. At this time, the mounting head 6 can be lifted, and the retaining ring 202 leaves the mounting groove 201 inside the metal connector plug 3, completing the disassembly. When the mounting head 6 needs to be reinstalled: Press the mounting head 6 downwards along the mounting groove 201. At this time, the retaining ring 202 contacts the inclined surface of the slider 203 and will push the slider 203 outwards. The slider 203 will drive the limiting rod 205 and the arc-shaped elastic plate 206 to slide outwards. At this time, the spring 204 is compressed. Until the retaining ring 202 moves below the bottom of the slider 203, the slider 203 will spring back inwards under the elastic force of the spring 204. The bottom of the slider 203 will lock the retaining ring 202, thus firmly locking the mounting head 6 in the mounting groove 201, realizing the disassembly, maintenance and recycling of the mounting head 6.
