Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an LC type connector. Background Technology

[0002] LC-type connectors are a type of fiber optic connector. Because their size is only half that of SC / ST / FC connectors, they belong to the Small Fiber Optic (SFF) connector category. Existing LC-type connectors typically include a front shell for mating with the fiber optic adapter, a clip for the fiber optic cable to pass through, and a rear shell for connecting the front shell and clip. The front and rear shells are usually connected by a snap-fit ​​mechanism. After the front shell of the LC-type connector is inserted into the adapter's interface, the connection is locked by a flexible cantilever. For example, utility model patent CN207882508U discloses an LC-type fiber optic connector including a bend limiting head, a ferrule adjuster, a top fixing plate, and a fiber optic coupling tube. The top fixing plate has a press-down wrench. However, during use, the flexible cantilever of the LC-type connector is subject to pressure deformation due to external forces such as impacts and cable pull-back, causing the connector to detach from the adapter. This results in poor reliability and inconvenience in use. Utility Model Content

[0003] The purpose of this utility model is to design an LC type connector to overcome the shortcomings of the above-mentioned technology. The locking or unlocking of the elastic cantilever is achieved through the operating component, which not only facilitates user operation, but also effectively prevents the connector body from being unlocked and detached due to collision or external force, thereby improving the reliability and ease of use of the LC type connector.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an LC type connector, comprising:

[0005] The connector body includes a front shell, a rear shell, a ferrule, and an operating member. The ferrule is disposed inside the front shell, and the front end of the ferrule extends to the outside of the front shell. The front shell and the rear shell are detachably connected. The front shell is provided with an elastic cantilever. The top surface of the rear shell near the elastic cantilever is provided with a sliding groove for the operating member to slide and connect. The inner wall of the sliding groove is provided with an outwardly protruding positioning part. The operating member is provided with two recessed positioning grooves along its sliding direction. The corresponding positioning grooves and positioning parts are in concave-convex fit. The top of the operating member extends out of the sliding groove and abuts against the inner side wall of the elastic cantilever.

[0006] Preferably, both sides of the positioning part are provided with inclined guide surfaces so that the cross-section of the positioning part is an isosceles trapezoid.

[0007] Preferably, the inner wall of the chute is provided with a guide groove, and the operating component is provided with a sliding guide part.

[0008] Preferably, the spacing between the guide grooves is greater than the thickness of the guide portion.

[0009] Preferably, the inner sidewall of the elastic cantilever is provided with a support groove, and the top front end of the operating member is provided with a support part, which is in concave-convex fit with the support groove.

[0010] Preferably, the front end shell has a mating groove communicating with its inner cavity, and the mating groove has at least one snap-fit ​​groove. The rear end shell has a connecting pipe communicating with its inner cavity. The connecting pipe is inserted into the mating groove, and the outer wall of the connecting pipe has a snap-fit ​​part that engages with the snap-fit ​​groove.

[0011] Preferably, it also includes an adapter housing, with slots provided at both ends of the adapter housing, the front end shell being inserted into the slots, and the elastic cantilever abutting against the opening side of the slots.

[0012] Preferably, the adapter housing has at least one through slot, and the elastic cantilever is provided with a locking part that engages with the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this LC-type connector, the front shell protects the ferrule and provides docking functionality with the adapter. The rear shell is detachably connected to the front shell to form an integral structure. The operating member can slide in a groove and is positioned by the cooperation of two positioning grooves and positioning parts, giving the operating member a locked and unlocked position. When the operating member is in the locked position, one of the positioning grooves engages with the positioning part, and the top of the operating member abuts against the inner wall of the elastic cantilever to support the elastic cantilever, maintain its position, and prevent it from deforming under pressure due to external forces, thereby ensuring... To ensure the reliable connection of the LC type connector, when the operating element is in the unlocked position, another positioning groove engages with the positioning part, separating the operating element from the elastic cantilever. The operating element no longer provides support for the elastic cantilever, and the user operates the elastic cantilever to deform it under pressure, thereby unlocking the LC type connector for insertion and removal of the connector body. The LC type connector locks or unlocks the elastic cantilever through the operating element, which not only facilitates user operation but also effectively prevents the connector body from being unlocked and detached due to collision or external force, thus improving the reliability and ease of use of the LC type connector.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 An LC-type connector includes a connector body 1 and an adapter housing 2. The connector body 1 includes a front housing 11, a rear housing 12, a ferrule 13, and an operating element 14. The ferrule 13 is disposed inside the front housing 11, and its front end extends to the outside of the front housing 11. The front housing 11 has a mating groove 110 communicating with its inner cavity. The mating groove 110 has two symmetrically arranged snap-fit ​​slots 111. The rear housing 12 has a connecting tube 112 communicating with its inner cavity. The connecting tube 112 is inserted into the mating groove 110. The outer wall of the connecting tube 112 has a snap-fit ​​part 113 that engages with the snap-fit ​​slots 111, so that the front housing 11 and the rear housing 12 can be detachably connected. Preferably, the rear housing 12 also has a tail sleeve 115 communicating with its inner cavity, and the tail sleeve 115 allows an optical fiber to extend into it.

[0022] Both ends of the adapter housing 2 are provided with slots 201, and the front end housing 11 is provided with an elastic cantilever 101. The front end housing 11 is inserted into the slot 201, and the elastic cantilever 101 abuts against the opening side of the slot 201. Moreover, the adapter housing 2 is provided with two symmetrically arranged locking slots 202, and the elastic cantilever 101 is provided with a locking part 114 that can be locked into the locking slot 202, thereby ensuring a reliable connection between the connector body 1 and the adapter housing 2.

[0023] A sliding groove 102 is provided on the top surface of the rear end housing 12 near the elastic cantilever 101 for the sliding connection of the operating member 14. A guide groove 106 is provided on the inner wall of the sliding groove 102. The operating member 14 is provided with a sliding connection guide part 107. The spacing of the guide grooves 106 is greater than the thickness of the guide part 107 to reserve space for the upward movement of the operating member 14. A protruding positioning part 103 is provided on the inner wall of the sliding groove 102. The operating member 14 is provided with two recessed positioning grooves 104 along its sliding direction. By sliding the operating member 14, the corresponding positioning groove 104 is made to engage with the positioning part 103. Both sides of the positioning part 103 are formed with inclined guide surfaces 105 so that the cross section of the positioning part 103 is an isosceles trapezoid, so that the operating member 14 can move upward under the guidance of the guide surfaces 105, thereby smoothly moving the other positioning groove 104 onto the positioning part 103.

[0024] In this LC type connector, the front shell 11 is used to protect the ferrule 13 and provide the function of docking with the adapter. The rear shell 12 is detachably connected to the front shell 11 to form an integral structure. The operating member 14 can slide in the slide groove 102 and is positioned by the cooperation of the two positioning grooves 104 and the positioning part 103, so that the operating member 14 has a locked position and an unlocked position.

[0025] When the operating member 14 is in the locked position, one of the positioning grooves 104 engages with the positioning part 103, and the top of the operating member 14 extends out of the sliding groove 102 and abuts against the inner wall of the elastic cantilever 101 to support the elastic cantilever 101, maintain its position, and prevent it from being deformed by external force, thereby ensuring the reliable connection of the LC type connector. Preferably, the inner wall of the elastic cantilever 101 is provided with a support groove 108, the inner wall of which is arc-shaped. The top front end of the operating member 14 is provided with a support part 109, which engages with the support groove 108 to ensure that the operating member 14 is aligned and supports the elastic cantilever 101.

[0026] When the operating member 14 is in the unlocked position, another positioning groove 104 engages with the positioning part 103, the operating member 14 separates from the elastic cantilever 101, the operating member 14 no longer provides support for the elastic cantilever 101, the user operates the elastic cantilever 101 to deform it under pressure, thereby unlocking the LC type connector so that the connector body 1 can be inserted or removed.

[0027] The LC type connector locks or unlocks the elastic cantilever 101 through the operating element 14, which not only facilitates user operation, but also effectively prevents the connector body 1 from being unlocked and detached due to collision or external force, thus improving the reliability and ease of use of the LC type connector.

[0028] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
