Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical fiber communication and power transmission, and particularly relates to an optical fiber adapter or an optical-electric hybrid adapter. BACKGROUND

[0002] The optical fiber adapter or the optical-electric hybrid adapter is an important connection component in the field of modern communication and power transmission, and its main function is to realize the butt joint between optical fibers or the butt joint between conductive connectors, so as to realize efficient signal transmission or power supply requirements.

[0003] In the prior art, the optical fiber adapter or the optical-electric hybrid adapter is usually fixed on a circuit board or other fixing member through a buckle. For example, in the optical-electric hybrid adapter, the conductive member on the adapter needs to be connected with the circuit board to supply power to the circuit board or realize data transmission. In order to realize stable fixation, the adapter shell is usually designed with a buckle structure.

[0004] However, the existing adapter buckle structure has the following disadvantages: the conventional buckle is usually provided with only a single step, and the distance between the step and the fixing member (such as a circuit board) is fixed. Such a design can only adapt to fixing members of a specific thickness, resulting in poor universality of the adapter.

[0005] Therefore, there is an urgent need for an improved adapter which can adapt to fixing members of different thicknesses through an innovative buckle design, so as to meet the universality requirements of optical fiber butt joint and optical-electric hybrid connection. The utility model discloses

[0006] The present application provides an adapter which can adapt to fixing members of different thicknesses through an innovative buckle design, thereby improving the applicability and reliability of the adapter.

[0007] The adapter provided by the present application comprises an outer shell, and at least one buckle is arranged on the outer side of the outer shell. A plurality of buckle steps with different distances from the outer side of the outer shell are formed on the buckle, so as to adapt to fixing members of different thicknesses.

[0008] As a preferred, the buckle comprises a base and a plurality of buckling members extending from the base, and a plurality of buckle steps with different distances from the outer side of the outer shell are arranged on each buckling member.

[0009] As a preferred, the buckle steps on the plurality of buckling members form a plurality of step groups, and each step group comprises a plurality of buckle steps on the buckling members with the same distance from the outer side of the outer shell.

[0010] As a preferred, the plurality of buckling members of the buckle have a preset gap therebetween, which is used to provide an elastic movement space of the buckle.

[0011] Preferably, the side of the plurality of buckling members of the buckle, which is away from the preset gap, is provided with a guide slope, so that the buckling member can elastically deform in the direction of the preset gap when subjected to a pressing force in the direction of the outer shell.

[0012] Preferably, the buckle has two buckles, and the two buckles are symmetrically arranged on the outer side of the outer shell.

[0013] The one or more technical solutions provided in the present application have at least the following technical effects or advantages:

[0014] The adapter of the present application optimizes the buckle structure, so that it can adapt to fixing members of various thicknesses, solving the problem of limited adaptation range of traditional buckles. The design of the preset gap and the guide slope improves the convenience of the assembly process and reduces the risk of damage to the fixing member or the adapter. The design of symmetrically arranging two adapter buckles further enhances the stability and reliability of the fixing, and is suitable for various application scenarios of optical fiber communication and optical-electric hybrid connection.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figs. 1-5 As shown, the adapter in this embodiment includes a housing 10, which includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are connected and fixed together.

[0030] Two latches 20 are provided on the outer side of the first outer shell 11, and the two latches 20 are symmetrical about the center line of the outer shell 10.

[0031] The buckle 20 has three buckle steps 221 at different distances from the outer side of the outer shell 10 to accommodate three different thicknesses of fasteners, which are circuit boards. After the buckle 20 passes through the through hole on the circuit board, it is engaged with the circuit board through the buckle steps 221. The distance between the buckle steps 221 and the outer shell 10 is adapted to the thickness of the circuit board, so that the adapter is securely fixed on the circuit board.

[0032] The adapter is secured to the fastener by two clips 20 to further enhance the stability and reliability of the adapter's fixation.

[0033] In other embodiments, the number of clips 20 can be one, three or more, the number of clip steps 221 on each clip 20 can be two, four or more, and the fastener can be other components besides the circuit board, such as fiber optic brackets, plastic brackets, metal plates, etc.

[0034] The buckle 20 includes a base 21 and two fasteners 22 extending from the base 21 in a direction away from the first outer shell 11. Each fastener 22 is provided with a plurality of buckle steps 221 at different distances from the outer side of the outer shell 10.

[0035] The latching steps 221 on the two fasteners 22 form multiple step groups. Each step group includes multiple latching steps 221 on the fasteners 22 that are equidistant from the outer side of the outer shell 10. In other words, the latching steps 221 included in each step group are on the same plane. Thus, when the latch 20 is fastened to the fastener, all the latching steps 221 included in one step group are fastened to the surface of the circuit board, thereby making the adapter more secure.

[0036] The two buckles 22 of the buckle 20 have a preset gap 23 therebetween for providing an elastic moving space of the buckle 20. The side of each of the plurality of buckles 22 of the buckle 20, which is away from the preset gap 23, is provided with a guide slope 222, so that when the guide slope 222 is pressed in the direction of the outer shell 10, the buckle 22 can elastically deform in the direction of the preset gap 23. Thus, the size of the buckle 20 is slightly larger than the hole diameter of the through hole of the circuit board. When the buckle 20 is inserted into the through hole of the circuit board, the periphery of the through hole of the circuit board exerts a force on the buckle 22 through the guide slope 222, so that the buckle 22 elastically deforms in the direction of the preset gap 23, thereby reducing the size of the buckle 20. The buckle 20 can smoothly pass through the through hole of the circuit board until the first outer shell 11 abuts against the first surface of the circuit board. At this time, the buckle step 221 matching the thickness of the circuit board is buckled on the second surface of the circuit board, thereby completing the buckling of the buckle 20 and the circuit board. The adapter of the present embodiment has three buckle steps 221 of different heights, thereby being able to adapt to the connection with three circuit boards of different thicknesses.

[0037] The adapter of the embodiment is provided with a first inner housing 30 in the first outer housing 11, the first inner housing 30 comprising a first base plate 31, a pair of first fixing clamps 32 and a first cylinder 33, a second inner housing 40 and two conductive members 60 in the second outer housing 12, the second inner housing 40 comprising a second base plate 41, a pair of second fixing clamps 42 and a second cylinder 43, the first outer housing 11 is fixedly connected with the second outer housing 12, the back surface of the first base plate 31 is engaged with the back surface of the second base plate 41, the pair of first fixing clamps 32 extends from the front surface of the first base plate 31 in the longitudinal direction, the first cylinder 33 is arranged between the two first fixing clamps 32, the pair of second fixing clamps 42 extends from the front surface of the second base plate 41 in the longitudinal direction, the second cylinder 43 is arranged between the two second fixing clamps 42, the first cylinder 33 and the second cylinder 43 are aligned with each other and communicated with each other, and a sleeve 50 is arranged in the passage formed by the first cylinder 33 and the second cylinder 43; the two conductive members 60 each comprise a side conductive sheet 61, a top conductive sheet 62 and a connecting sheet 63 made of conductive material, the two side conductive sheets 61 are respectively arranged on the inner walls of the two sides of the second outer housing 12, the two top conductive sheets 62 are respectively arranged on the left and right sides of the top wall of the second outer housing 12, and the two connecting sheets 63 extend outwardly from the second outer housing 12. When the adapter is used, the two fiber connectors are respectively inserted into the first outer housing 11 and the second outer housing 12, the two first fixing clamps 32 and the two second fixing clamps 42 respectively clamp and fix the two fiber connectors, and the fiber connectors are connected in the sleeve 50, the sleeve 50 is generally made of ceramic material, and meanwhile, the two side walls or the top wall of the fiber connector in the second outer housing 12 is further provided with a conductive connecting part, the conductive connecting parts on the two side walls of the fiber connector can respectively contact and conduct electricity with the two side conductive sheets 61, and the two conductive connecting parts on the top wall of the fiber connector can respectively contact and conduct electricity with the two top conductive sheets 62, and after the adapter is fixed to the circuit board by the two buckles 20, the two connecting sheets 63 are respectively welded to the conductive ports on the circuit board, so that the fiber connector in the second outer housing 12 can supply power to the circuit board through the conductive member 60 to realize the photoelectric hybrid transmission of the adapter.

[0038] A first dustproof plug 70 is arranged at the open end of the first shell 11 to achieve dustproof of the interior of the first shell 11, and a first sleeve 71 extending longitudinally is arranged on the inner wall of the first dustproof plug 70, when the first dustproof plug 70 is plugged into the open end of the first shell 11, the first sleeve 71 is sleeved on the first cylinder 33 to fix the first dustproof plug 70 stably; a second dustproof plug 81 is arranged at the open end of the second shell 12 to achieve dustproof of the interior of the second shell 12, and a second sleeve 81 extending longitudinally is arranged on the inner wall of the second dustproof plug 80, when the second dustproof plug 80 is plugged into the open end of the second shell 12, the second sleeve 81 is sleeved on the second cylinder 43 to fix the second dustproof plug 80 stably.

[0039] In other embodiments, the adapter does not have two conductive parts 60, and only the optical fiber can be connected.

[0040] In other embodiments, the conductive part of the adapter extends from the first shell 11 to the second shell 12, which can conduct the conductive connection of the two optical fiber connectors, so that the two optical fiber connectors can not only realize optical fiber butt joint, but also realize current butt joint, to realize optical and electrical hybrid transmission.
