Description

Technical Field

[0001] This utility model relates to the field of MPO technology, and in particular to a snap-fit ​​assembly structure for MPO. Background Technology

[0002] MPO fiber optic patch cords and MPO connectors are part of the MT series connectors. The MT series ferrules use two 0.7mm diameter guide holes on the left and right sides of the ferrule end face to connect precisely with the guide pins. The MPO's snap-fit ​​assembly structure uses elastic snaps to achieve a stable lock, ensuring the stability and reliability of the connector during use.

[0003] A search revealed Chinese patent "An MPO Anti-Loosening Clip" (publication number CN222866909U). This utility model relates to an MPO anti-loosening clip, comprising a collar for fitting onto the outer shell of an MPO connector, a locking plate arranged above and / or below the collar, the middle of the locking plate rotatably engaging with the collar, and a locking protrusion at the rear end of the locking plate that engages with a movable groove formed between the rear end of the outer shell and the rear end of the inner shell of the MPO connector, preventing the outer shell from retracting relative to the inner shell. The beneficial effect is that, to keep the MPO connector locked, the locking plate rotates around its connection point with the collar until the locking protrusion engages with the movable groove formed between the rear end of the outer shell and the rear end of the inner shell of the MPO connector. Even if the fiber optic patch cord has a certain weight, the clip of the MPO adapter will not loosen from the MPO connector. This anti-loosening clip can be applied to existing MPO connectors without requiring modifications to the MPO connector itself.

[0004] Although the aforementioned MPO latch can engage with the MPO connector by placing the locking protrusions of the latch plate into the movable slot, the latch plate is limited only by a rotating shaft, and the lower latch plate is subjected to greater force. Therefore, in actual use, the MPO connector is still prone to loosening due to fiber optic patch cords. Utility Model Content

[0005] Therefore, it is necessary to provide a snap-fit ​​assembly structure for MPO to address the problems of the aforementioned MPO snap-fit ​​assembly structure lacking locking effect and being prone to loosening of the MPO connector due to optical jumpers.

[0006] A snap-fit ​​assembly structure for an MPO includes: a locking sleeve body sleeved on the surface of a connector, wherein transition plates are provided above and below the locking sleeve body;

[0007] A locking component, which is disposed on the surface of the locking sleeve body and is capable of locking the angle of the transformation plate;

[0008] The locking component includes an integral shell disposed on the surface of the locking sleeve body, and a locking ball embedded in the conversion plate is disposed inside the integral shell.

[0009] In one embodiment, the locking assembly further includes a groove formed in an integral housing, the inner wall of the groove being fixedly connected to a spring, and the spring having a telescopic rod fixed to the inner wall of the groove.

[0010] In one embodiment, the locking ball has a groove on the side near the spring, and the ends of the spring and the telescopic rod near the locking ball are both fixedly connected to the inner wall of the groove.

[0011] In one embodiment, the conversion plate has an arc-shaped groove on the side near the integral shell, and the locking ball is located in the arc-shaped groove.

[0012] In one embodiment, the ratio of the locking ball located in the integral shell and the arcuate groove is six to four.

[0013] In one embodiment, an extension is provided at the rear of the integral shell, the extension being located above the conversion plate.

[0014] In one embodiment, locking protrusions are fixedly connected to the front ends of the two conversion plates on opposite sides. The locking protrusions are used to engage with the grooves of the connector and prevent the connector from becoming loose due to fiber optic patch cords.

[0015] In one embodiment, grooves are provided on both the upper and lower sides of the locking sleeve body, and a rotating shaft is fixedly connected to the inner wall of the groove, with the transformation plate movable on the surface of the rotating shaft.

[0016] Beneficial effects

[0017] 1. By setting the locking ball of the locking component, after the converter plate is moved to a certain position, the locking ball can extend into the arc groove by means of spring and telescopic rod, which can limit the angle of the converter plate and prevent the converter plate from being affected by the fiber optic patch cord and reducing the locking effect on the connector.

[0018] 2. By setting the extension of the integrated shell, the lower conversion plate can be supported, preventing the lower conversion plate from changing angle due to the weight of the fiber optic patch cord and causing the locking protrusion to loosen. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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 some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figure 1 - Figure 5 This invention describes a snap-fit ​​assembly structure for MPO.

[0029] In one embodiment, a snap-fit ​​assembly structure for an MPO includes: a locking sleeve body 1 sleeved on the surface of a connector, wherein a transition plate 2 is provided above and below the locking sleeve body 1;

[0030] Locking component 3, which is disposed on the surface of the locking sleeve body 1 and can lock the angle of the transformation plate 2;

[0031] How the MPO latch works: The latch on top of the MPO connector is a flexible arm. When the adapter is inserted, the latch arm is pressed down until it clicks into the corresponding slot of the adapter, completing the locking. When you need to remove it, press the latch arm with your finger to release the engagement with the adapter slot, and you can pull out the connector. However, when the fiber optic patch cord is subjected to tension, torque, or accidental scratches, the force may be transmitted to the latch arm, causing it to be accidentally partially or completely pressed down, thereby releasing the locking state and causing the connector to come loose from the adapter.

[0032] At the rigid connection between the latch arm and the connector body, there is usually a natural recess. Therefore, after the conversion plate 2 drives the locking protrusion 4 to rotate to a horizontal state, the locking protrusion 4 will be embedded in the root recess area between the MPO connector latch arm and the connector. In this way, the phenomenon of the MPO adapter latch and the MPO connector becoming loose can be avoided.

[0033] First, the locking sleeve body 1 is placed on the surface of the connector. Then, the conversion plate 2 is moved to the horizontal position so that the locking protrusion 4 at the end of the conversion plate 2 can be embedded in the groove between the outer shell of the snap-fit ​​structure and the connector, thereby limiting the position of the connector.

[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the locking assembly 3 includes an integral shell 301 disposed on the surface of the locking sleeve body 1, and a locking ball 304 embedded in the conversion plate 2 is disposed inside the integral shell 301; the locking assembly 3 also includes a groove formed in the integral shell 301, and a spring 302 is fixedly connected to the inner wall of the groove, and a telescopic rod 303 fixed to the inner wall of the groove is disposed inside the spring 302; a groove is formed on the side of the locking ball 304 near the spring 302, and the ends of the spring 302 and the telescopic rod 303 near the locking ball 304 are both fixedly connected to the inner wall of the groove; an arc-shaped groove is formed on the side of the conversion plate 2 near the integral shell 301, and the locking ball 304 is located in the arc-shaped groove; the ratio of the locking ball 304 in the integral shell 301 and the arc-shaped groove is 6:4;

[0035] When the conversion plate 2 changes angle to the horizontal state, the end face of the conversion plate 2 near the locking ball 304 will first contact the arc surface of the locking ball 304. Then the locking ball 304 will be retracted into the groove by the arc surface. At this time, the spring 302 will be in a contracted state after being compressed. When the conversion plate 2 is completely turned to the horizontal state, the locking ball 304 will lose its restriction. At this time, the spring 302 will drive the locking ball 304 to extend outward, and four-tenths of the locking ball 304 will extend into the arc groove, so that the locking ball 304 is engaged between the integrated shell 301 and the conversion plate 2, which can lock the conversion plate 2 without large external force and can withstand the fiber optic patch cord.

[0036] An extension 305 is provided at the rear of the integrated shell 301, and the extension 305 is located above the conversion plate 2.

[0037] By providing the extension 305 of the integrated housing 301, the lower conversion plate 2 can be supported, preventing the lower conversion plate 2 from changing angle due to the weight of the fiber optic patch cord and causing the locking protrusion 4 to loosen.

[0038] Locking protrusions 4 are fixedly connected to the front ends of the two conversion plates 2 on opposite sides. The locking protrusions 4 are used to engage with the groove of the connector and prevent the connector from coming loose due to the fiber optic patch cord. The upper and lower sides of the locking sleeve body 1 are provided with grooves. The inner wall of the groove is fixedly connected to a rotating shaft. The conversion plate 2 moves on the surface of the rotating shaft.

[0039] Working principle: In actual use, firstly, the locking sleeve body 1 is placed on the surface of the connector. Then, the adapter plate 2 is moved to the horizontal position, so that the locking protrusion 4 at the end of the adapter plate 2 can be embedded in the groove between the snap-fit ​​structure shell and the connector, thus limiting the connector. When the adapter plate 2 changes to the horizontal position, the end face of the adapter plate 2 near the locking ball 304 will first contact the arc surface of the locking ball 304. Then, the locking ball 304 will be retracted into the groove by the arc surface. At this time, the spring 302 will be in a contracted state after being compressed. When the adapter plate 2 is completely moved to the horizontal position, the locking ball 304 will lose its restriction. At this time, the spring 302 will drive the locking ball 304 to extend outward, and four-tenths of the locking ball 304 will extend into the arc groove, so that the locking ball 304 is snapped between the integrated shell 301 and the adapter plate 2. The adapter plate 2 can be locked without large external force and can withstand the fiber optic patch cord.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
