Description

Technical Field

[0001] The utility model relates to the technical field of fiber optic jumpers, in particular to a snap - lock type fiber optic jumper. Background Art

[0002] A fiber optic jumper is a patch cord used to connect a device to a fiber optic cabling link and is also known as a fiber optic connector. It mainly consists of connector plugs installed at both ends of an optical cable and is used to achieve an optical path active connection. Fiber optic jumpers are widely used in fields such as fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

[0003] In the prior art, fiber optic jumpers are mostly divided into LC type and ST type. Among them, for LC type fiber optic jumpers, if the force during the insertion and extraction of the fiber optic connector is too large or too small, the connector may become loose. Excessive force may damage the internal structure of the connector, while too little force may not fully fix the connector. Although the ST type fiber optic jumper has a tight connection, it needs to be rotated half a turn for fixation after insertion and is prone to breakage due to improper operation.

Specific embodiments

[0025] The following will further elaborate on the present utility model with reference to the accompanying drawings.

[0026] Embodiment:

[0027] Referring to Figures 1 - 5 , a snap - type fiber optic jumper disclosed by the present utility model includes a connecting element 1. Both ends of the connecting element 1 are fixedly connected with sockets 2. A first guide plate 3 is arranged at the bottom end of the socket 2. On both sides of the end of the first guide plate 3 close to the socket 2, there are connecting plates 4. The top ends of the two connecting plates 4 are jointly rotatably connected with a second guide plate 5;

[0028] A positioning slide plate 6 is arranged inside the first guide plate 3. The positioning slide plate 6 is arc-shaped, and a lead plug 7 is slidably arranged inside the positioning slide plate 6. A lead fixing structure 8 is arranged at one end of the lead plug 7 away from the socket 2. A locking structure 9 is slidably arranged on the outer surface of the first guide plate 3;

[0029] A push-lock structure 10 is arranged at one end of the second guide plate 5 away from the connecting plate 4 inside.

[0030] In this embodiment, during use, the push-lock mechanism is removed, and the second guide plate 5 is lifted upward. As Figure 1 and Figure 2 shown, at this time, the lead plug 7 can be pulled out from inside the first guide plate 3 and the second guide plate 5. At this time, the optical cable is fixed to one end of the lead plug 7 through the lead fixing structure 8. Then, the lead plug 7 is slid into the positioning slide plate 6, and the lead plug 7 is inserted into the socket 2. Then, the second guide plate 5 is closed. During the closing process of the second guide plate 5, a thrust is applied to the lead plug 7 through the push-lock structure 10, so that the lead plug 7 and the socket 2 are tightly closed, so as to achieve the purpose of improving the stability of the optical cable connection, effectively fixing the thrust on the lead plug 7, thereby avoiding the problem of damage to the internal structure of the connector caused by excessive plugging and unplugging force, or avoiding the problem that the connector cannot be fixed due to too small plugging force, thus effectively improving the stability of the wire connection, and there is no need to rotate the optical fiber during connection, effectively avoiding the problem of optical fiber breakage caused by twisting the optical fiber.

[0031] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the push-lock structure 10 includes a support push plate 101. The outer arc surface of the support push plate 101 fits with the inner arc surface of the second guide plate 5. A connecting hinge 102 is jointly arranged at one end of the support push plate 101 and the second guide plate 5. An elastic plate 103 is arranged at the top end of the support push plate 101.

As Figure 2As shown in the figure, when installing the lead plug 7, slide the lead plug 7 into the inside of the positioning slide plate 6 until the outer wall of the lead plug 7 contacts the bottom end of the support push plate 101. Then, press the second guide plate 5 downward until it contacts the first guide plate 3. During the process of pressing the second guide plate 5 downward, the included angle between the support push plate 101 and the second guide plate 5 will gradually decrease. At this time, the support push plate 101 will push the lead plug 7 to move in one direction, thereby achieving the purpose of connecting the lead plug 7 with the socket 2, effectively limiting the force for inserting the lead plug 7, and further avoiding the problem of connector loosening caused by excessive or insufficient force.

[0033] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, a support plate 71 is provided at the top end of the lead plug 7, and the outer arc surface of the support plate 71 is matched with the inner arc surface of the second guide plate 5.

[0034] In this embodiment, the support plate 71 is provided to position the position where the lead plug 7 slides into the inside of the positioning slide plate 6. Specifically, when installing the lead plug 7, slide the lead plug 7 into the inside of the positioning slide plate 6 until the outer wall of the lead plug 7 contacts the bottom end of the support push plate 101 and the bottom end of the support push plate 101 is opposite to the side of the support plate 71 facing the lead fixing structure 8. During the process of pressing the second guide plate 5 downward, the support push plate 101 can push the support plate 71 to achieve the purpose of sliding the lead plug 7 in the positioning slide plate 6, thereby achieving the purpose of connecting the lead plug 7 with the socket 2.

[0035] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, jacks 11 for installing optical cables are provided at the corresponding positions of the socket 2 and the lead plug 7, and a plurality of positioning holes 21 are provided at positions near the edge of one end of the socket 2 facing the lead plug 7.

[0036] In this embodiment, the jacks 11 are provided for installing optical cables to achieve the purpose of connecting two optical cables, and the positioning holes 21 are provided for connecting the lead plug 7.

[0037] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, positioning pins 72 corresponding to the positioning holes 21 are provided at the positions of the lead plug 7 corresponding to the positioning holes 21.

[0038] In this embodiment, the positioning pins 72 are provided to cooperate with the positioning holes 21 to position the connection position between the lead plug 7 and the socket 2;

[0039] Specifically, when the lead plug 7 slides into the inside of the positioning slide plate 6 until the outer wall of the lead plug 7 contacts the bottom end of the support push plate 101 and the bottom end of the support push plate 101 is opposite to the side of the support plate 71 facing the lead fixing structure 8, the end of the positioning pin 72 is inserted into the inside of the positioning hole 21. Then, when the second guide plate 5 is pressed downward until it is closed with the first guide plate 3, the movement track of the lead plug 7 is fixed, thereby effectively improving the connection stability between the lead plug 7 and the socket 2.
