[0019] like Figures 1-10 As shown, an easy-to-assemble optical fiber connection device includes a female connector assembly 11 and a ferrule module.

[0020] Among them, such as Figure 2 As shown, the ferrule module includes a ferrule base 51, a ferrule tail 52, a ferrule 53, and a spring 54. The ferrule tail 52 and the ferrule 53 are fixed to each other and are provided in two sets, upper and lower. The ferrule tail 52 is installed in the ferrule base 51, and the ferrule 53 passes through the ferrule base 51. The spring 54 presses on both ferrule tails 52 at the same time.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the female head assembly 11 includes a double female shell 21, with a front sleeve 22 and a tail sleeve 23 respectively provided at both ends of the double female shell 21. One of the insert modules is installed in the front sleeve 22, that is, the insert seat 51 is slidably connected in the front sleeve 22, and the insert 53 extends out of the front sleeve 22 in a direction away from the double female shell 21. The other end of the spring 54 in the insert module presses against the double female shell 21.

[0022] Through the above design, when assembling the female connector assembly 11, the operator can first assemble the ferrule module, then install the ferrule module into the front sleeve 22, and finally connect the front sleeve 22 to the double-unit female shell 21. This process makes the assembly of the easy-to-assemble optical fiber connection device simpler and also eliminates the risk of interference between the two ferrules 53.

[0023] Furthermore, one side of the double-shell 21 is equipped with a sleeve 24 extending into the tail sleeve 23, the sleeve 24 being used to fix the optical cable that extends into the double-shell 21 after passing through the tail sleeve 23.

[0024] The specific path of the optical cable within the female connector assembly 11 is as follows: the optical cable passes through the tail sleeve 23, then through the clamp 24 and is fixed inside the double-ended female shell 21. After that, the optical cable passes through the spring 54 and extends into the ferrule tail 52, allowing the optical fiber inside to pass through the ferrule 53.

[0025] The connection method of the double female shell 21, the front sleeve 22 and the tail sleeve 23 in the female head assembly 11 is as follows: the tail sleeve 23 is provided with a fourth buckle 63 so as to be connected and fixed with the double female shell 21, and the double female shell 21 is provided with a fifth buckle 64 so as to be connected and fixed with the front sleeve 22.

[0026] In this embodiment, the spring 54 provides a preload force so that the ferrule module tends to move outward (away from the direction of the double female shell 21) and so that the ferrule end face can make tight contact when the female head assembly 11 contacts the male head.

[0027] In a second embodiment of the easily assembled fiber optic connection device, such as Figure 5 As shown, it also includes a male connector 12 and an adapter 13 to cooperate with the female connector 11 and form a complete fiber optic connection link.

[0028] Specifically, such as Figure 6 and Figure 7 As shown, the male connector assembly 12 includes a double male housing 31, a ferrule module is installed in the double male housing 31 such that the ferrule seat 51 is slidably connected to the double male housing 31, the ferrule 53 extends to the outside of the double male housing 31, and the other end of the spring 54 presses against the end face inside the double male housing 31.

[0029] like Figure 8 As shown, the adapter 13 is provided with a slot 41, and the slot 41 is provided with a separator 42 to divide the slot 41 into two sockets, which respectively accommodate the female connector assembly 11 and the male connector assembly 12. The separator 42 is provided with two ceramic sleeves 43 to accommodate the two ferrules 53 in the female connector assembly 11 and the male connector assembly 12.

[0030] Furthermore, to facilitate the installation of the ceramic sleeve 43, the separator includes a first sleeve plug 44 and a second sleeve plug 45 symmetrically distributed. The first sleeve plug 44 is integrally formed in the slot 41, and the second sleeve plug 45 is fixed to the first sleeve plug 44 by a first buckle. The ceramic sleeve 43 is sandwiched between the first sleeve plug 44 and the second sleeve plug 45.

[0031] In this embodiment, the slot 41 is provided with six slots that are equidistantly distributed in the front and back of the adapter 13, so that one adapter 13 can accommodate six female connector components 11 and six male connector components 12, and allow the female connector components 11 and the male connector components 12 to be connected.

[0032] The female connector assembly 11, the male connector assembly 12 and the adapter 13 are interconnected by means that the double female shell 21 and the double male shell 31 are respectively integrally formed with a second buckle 61 and a third buckle 62, so that they can be fixed in the adapter 13 respectively.

[0033] In this embodiment, both the second buckle 61 and the third buckle 62 are cantilever elastic buckles. The locking protrusion inside the third buckle 62 faces downward so that it can be fastened into the adapter 13 for easy disassembly and assembly. The locking protrusion inside the second buckle 61 faces upward. In order to allow the female head assembly 11 to be removed from the adapter 13, the second buckle 61 is also integrally formed with a sloping protrusion 71. In addition, the double-walled female shell 21 is provided with a hook groove for cooperating with the fourth buckle 63, and the lateral width of the hook groove is greater than the left and right width of the locking protrusion in the fourth buckle 63, so that the tail sleeve 23 can move laterally a certain distance relative to the double-walled female shell 21. It also includes a locking plate 72, which is fixed to the tail sleeve 23 and covers the second buckle 61. The locking boss inside the second buckle 61 is located outside the locking plate 72, and the locking plate 72 is provided with a slot for the inclined boss 71 to protrude upward.

[0034] The inclined surface inside the inclined boss 71 presses against one side of the empty groove, causing the double female shell 21 and the tail sleeve 23 to be tightly pressed together. When the female head assembly 11 needs to be pulled out, the operator pulls the tail sleeve 23 to the right, causing the tail sleeve 23 to move to the right relative to the double female shell 21. At this time, the locking plate 72 presses against the inclined surface inside the inclined boss 71, causing the left edge of the second buckle 61 to bend downward and be able to disengage from the adapter 13. At this time, the double female shell 21 can also disengage from the adapter 13.

[0035] Furthermore, such as Figure 9As shown, it also includes a dust cover 81, which has a accommodating cavity for accommodating the front sleeve 22 and has a one-way opening. The upper side of the accommodating cavity has a notch for engaging the second buckle 61. The dust cover 81 is needed to protect the female head assembly 11 before it is inserted into the adapter 13. Similarly, the operator can also pull the tail sleeve 23 to make the second buckle 61 bend downward and make the dust cover 81 disengage from the female head assembly 11.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
