[0018] The following is combined with Figure 1-2This application is described in further detail.

[0019] The present application embodiment discloses an optical fiber connector, referring to Figure 1 and Figure 2 A fiber optic connector includes a connector body 1. The connector body 1 adopts a common fiber optic connector on the market. The connector bodies 1 are used in pairs to connect two optical fibers. The fiber optic connector also includes a reinforcement sleeve 2, a connection component 3 and a fixing component 4. The reinforcement sleeve 2 is a block with the same cross-sectional edge and outer diameter as the connector body 1. A hole for the optical fiber to pass through is opened in the reinforcement sleeve 2. The optical fiber passes through the reinforcement sleeve 2. The reinforcement sleeve 2 is arranged at one end of the connector body 1 away from the joint. The connection component 3 is arranged on the reinforcement sleeve 2. The connection component 3 is connected to the connector body 1. The connection component 3 is used to fix the reinforcement sleeve 2 to the connector body 1. The fixing component 4 is arranged on the reinforcement sleeve 2 and connected to the optical fiber inserted into the reinforcement sleeve 2. The fixing component 4 is used to fix and limit the optical fiber.

[0020] By adding a reinforcement sleeve 2 to the connector body 1, the reinforcement sleeve 2 is fixedly connected to the connector body 1 through the connecting component 3, and the fixing component 4 fixes and limits the optical fiber inserted into the reinforcement sleeve 2, so that the connection between the optical fiber and the connector body 1 is reinforced through the reinforcement sleeve 2, and the tension exerted on the optical fiber is directly applied to the outer shell of the connector body 1 through the reinforcement sleeve 2, thereby improving the current problem of low tensile strength caused by the optical fiber being directly clamped on the connector body 1.

[0021] Reference Figure 1 and Figure 2 The connection assembly 3 includes a card plate 31 and a card block 32. A plurality of card plates 31 are arranged around the side of the reinforcing sleeve 2 close to the connector body 1. In this embodiment, the cross section of the connector body 1 is rectangular. Four card plates 31 are arranged around the reinforcing sleeve 2. The four card plates 31 correspond to the four sides of the reinforcing sleeve 2 respectively. In other embodiments, when the cross section of the connector body 1 is circular, the card plates 31 can be multiple arc-shaped plates arranged around. The card block 32 is arranged at the end of the card plate 31 away from the reinforcing sleeve 2. The card block 32 makes the end of the card plate 31 inverted triangle shape. A plurality of card slots 11 for inserting the card blocks 32 are arranged around the end of the connector body 1 close to the reinforcing sleeve 2. The reinforcing sleeve 2 and the snap-on piece 31 are both made of hard plastic. The snap-on piece 31 has a certain elasticity. When the reinforcing sleeve 2 is installed on the connector body 1, the reinforcing sleeve 2 is placed on the connector body 1, and the snap-on block 32 is snapped into the snap-on groove 11 on the connector body 1, so as to facilitate the connection of the reinforcing sleeve 2 to the connector body 1.

[0022] Reference Figure 1 and Figure 2The connection assembly 3 also includes an anti-dropping block 33 and a pressing ring 34. The anti-dropping block 33 is arranged on the side of the clamping piece 31 away from the clamping block 32, and the pressing ring 34 is slidably arranged on the reinforcing sleeve 2. In the initial position, the pressing ring 34 is located on the reinforcing sleeve 2. When the reinforcing sleeve 2 is sleeved on the connector body 1, the multiple clamping pieces 31 are first opened, and after the clamping block 32 is clamped into the clamping groove 11, the multiple clamping pieces 31 return to their original state. At this time, the pressing ring 34 is moved to contact the anti-dropping block 33, and the pressing ring 34 tightens the multiple clamping pieces 31, so that the multiple clamping pieces 31 cannot be opened, and then the reinforcing sleeve 2 is stably fixed on the connector body 1, so that the connection between the reinforcing sleeve 2 and the connector body 1 is stable.

[0023] Further, see Figure 1 and Figure 2 , the pressing ring 34 is connected with a hanging ear 35, and the hanging ear 35 is arranged on both sides of the pressing ring 34. The two connected connector bodies 1 are connected with a reinforcing sleeve 2, and a fixing rope 36 is connected between the hanging ears 35 on the two reinforcing sleeves 2. After the two connector bodies 1 are connected in place, the fixing rope 36 is connected between the two pressing rings 34. The fixing rope 36 is a steel wire rope with a diameter of 1mm, and the fixing rope 36 is fixed between the two pressing rings 34 through a thin steel wire buckle. The two reinforcing sleeves 2 are fixed by the fixing rope 36, and the two reinforcing sleeves 2 are connected as a whole, which further improves the overall tensile strength of the optical fiber connector.

[0024] Reference Figure 1 and Figure 2 The fixing assembly 4 includes a fixing ball 41, a retaining frame 42 and a spring 43. A fixing groove 21 is formed around the inner wall of the reinforcing sleeve 2. The cross-sectional shape of the fixing groove 21 is a right-angled trapezoid. The depth of the fixing groove 21 near the connector body 1 is greater than the depth of the fixing groove 21 away from the connector body 1. The retaining frame 42 is an annular plate and is located in the fixing groove 21. The outer wall of the retaining frame 42 is parallel to the bottom wall of the fixing groove 21, and the inner wall of the retaining frame 42 is flush with the inner wall of the reinforcing sleeve 2. In this embodiment, a plurality of fixing balls 41 are embedded around the retaining frame 42, and the plurality of fixing balls 41 can roll while being unable to detach from the retaining frame 42. In other embodiments, a plurality of horn holes 421 are formed around the retaining frame 42. The inner diameter of the horn hole 421 near the axis of the retaining frame 42 is small, and the inner diameter of the end away from the axis of the retaining frame 42 is large. The fixing ball 41 is located in the horn hole 421, and both sides of the fixing ball 41 extend to the outside of the retaining frame 42. The spring 43 is disposed on the reinforcing sleeve 2 and is located in the fixing groove 21 . The spring 43 is always in a compressed state, so that the spring 43 makes the retaining frame 42 always have a tendency to move away from the connector body 1 .

[0025] In the initial position, the retainer 42 is located at the shallow end of the fixing groove 21 under the action of the spring 43. At this time, one side of the fixing ball 41 contacts the optical fiber, and the other end of the fixing ball 41 contacts the bottom wall of the fixing groove 21. When the optical fiber is subjected to external tension, the optical fiber has a tendency to move away from the connector body 1. At this time, the optical fiber has a tendency to drive the fixing ball 41 to move toward the shallow end of the fixing groove 21. The gap between the fixing ball 41 and the optical fiber has a tendency to decrease, so that multiple fixing balls 41 clamp the light on the reinforcing sleeve 2, and the tension received by the optical fiber is transmitted to the connector body 1 structure through the reinforcing sleeve 2, thereby improving the tensile strength of the connector.

[0026] Furthermore, in other embodiments, a plurality of fixing components 4 may be provided in the reinforcing sleeve 2, and the plurality of fixing components 4 may jointly fix the optical fiber, thereby further improving the stability of the reinforcing sleeve 2 in fixing the optical fiber, thereby further improving the tensile strength.

[0027] The implementation principle of an optical fiber connector in an embodiment of the present application is as follows: a reinforcement sleeve 2 is added to the connector body 1, and the reinforcement sleeve 2 is fixedly connected to the connector body 1 through a connecting component 3, and a fixing component 4 fixes and limits the optical fiber inserted into the reinforcement sleeve 2, thereby reinforcing the connection between the optical fiber and the connector body 1 through the reinforcement sleeve 2, and the tensile force exerted on the optical fiber is directly applied to the outer shell of the connector body 1 through the reinforcement sleeve 2, thereby improving the problem of low tensile strength caused by the current direct clamping of the optical fiber on the connector body 1.
