Description

Technical Field

[0001] The utility model belongs to the field of optical fiber communication equipment, and specifically relates to an optical fiber adapter. Background Art

[0002] A fiber optic adapter is a component used to connect fiber optic devices. It plays a key role in fiber optic communication systems. The main function of a fiber optic adapter is to precisely align two optical fibers to ensure that optical signals can be transmitted efficiently and losslessly between the fibers.

[0003] When testing optical fibers through optical fiber test equipment, it is necessary to connect the optical fibers to be tested with different plugs to the optical fiber test equipment through adapters, and it is necessary to replace adapters with different adapter bodies according to the plugs of the optical fibers to be tested. For example, when the optical fiber connection plug is an SC head, the adapter body in the adapter should be an SC adapter inner body; when the optical fiber connection plug is an FC head, the adapter body in the adapter should be an FC adapter inner body. In existing technologies, optical fiber adapters are usually fastened to the panel of optical fiber test equipment by structures such as bolts. When the plug of the optical fiber to be tested is changed, the optical fiber adapter needs to be removed from the inside of the optical fiber test equipment for replacement. This is not only cumbersome and inefficient, but also easily affects other precision components inside the optical fiber test equipment during the removal process. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide an optical fiber adapter.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The optical fiber adapter includes a quick connector, in which an adapter body for connecting optical fiber test equipment and the optical fiber to be tested is assembled, and one end of the adapter body extending outside the quick connector is sleeved with a base for connecting to the optical fiber test equipment; the quick connector is movably connected to two or more locking hooks for locking on both sides of the base, and the locking hooks are connected to the quick connector by an elastic member, and the locking hooks are locked to the base under the elastic force of the elastic member.

[0007] Preferably, the locking hook is rotatably connected to the quick connector via a hinge shaft.

[0008] Preferably, the contact end between the locking hook and the base is provided with a clamping joint for clamping on the clamping surface of the base.

[0009] Preferably, the card joint and the elastic member are respectively located on both sides of the hinge shaft; when the end of the lock hook is pressed away from the card joint to compress the elastic member, the card joint releases the card contact limit on the base card surface, allowing the base to be separated from the quick joint.

[0010] Preferably, the elastic member is a compression spring, an elastic pressing sheet, or a compression rubber.

[0011] Preferably, the card joint is provided with a pressure-bearing inclined surface that cooperates with the inclined pressure surface of the base on the side close to the quick joint. When the base moves toward the quick joint, the inclined pressure surface of the base presses against the pressure-bearing inclined surface of the card joint, causing the card joint to move away from the quick joint and drive the locking hook to compress the elastic part.

[0012] Preferably, one end of the elastic member is inserted into the first receiving groove on the inner side surface of the lock hook and contacts the inner wall of the first receiving groove.

[0013] Preferably, the other end of the elastic member is inserted into the second accommodating groove on the outer side surface of the quick connector and is sleeved on the central column in the middle of the second accommodating groove.

[0014] Preferably, an end of the quick connector away from the base is provided with an open opening, and an end cover for protecting the adapter body assembled in the quick connector is inserted into the open opening.

[0015] Preferably, one side of the end cap and the quick connector connection end is clamped in the clamping interface of the quick connector through an elastic clamping block, and the other end of the end cap and the quick connector connection end is connected to the quick connector through a bolt.

[0016] The utility model has the following beneficial effects:

[0017] The fiber optic adapter of the utility model has a base for stably connecting to fiber optic test equipment. The base and the quick connector equipped with the adapter body are connected by two or more locking hooks for locking on both sides of the base. When a different adapter body needs to be replaced, it is only necessary to control the locking hooks to release the limit on the base to separate the quick connector from the base, which is convenient for replacing quick connectors with different adapter bodies to meet the testing needs of optical fibers to be tested with different plugs. The operation is convenient and saves time and effort.

[0028] The following description and accompanying drawings sufficiently illustrate the specific embodiments herein to enable those skilled in the art to practice them. Portions and features of some embodiments may be included in or substituted for portions and features of other embodiments. The scope of the embodiments herein includes the entire scope of the claims, including all available equivalents thereof. Herein, the terms "first," "second," and the like are used solely to distinguish one element from another and do not require or imply any actual relationship or order between these elements. In practice, the first element can also be referred to as the second element, and vice versa. Furthermore, the terms "comprise," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a structure, device, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such structure, device, or apparatus. Without further limitation, an element defined by the phrase "comprising a..." does not preclude the presence of other identical elements in the structure, device, or apparatus comprising the element. The various embodiments herein are described in a progressive manner, with each embodiment focusing on its differences from the other embodiments. Similar or identical parts between the various embodiments can be referenced to each other.

[0029] The following is combined with Figure 1-7 The utility model is described in further detail.

[0030] like Figure 1As shown, the optical fiber adapter includes: a quick connector 1, in which an adapter body 2 for connecting the optical fiber test equipment and the optical fiber to be tested is assembled, and one end of the adapter body 2 extending outside the quick connector 1 is sleeved with a base 3 for connecting the optical fiber test equipment; the quick connector 1 is movably connected to two or more locking hooks 4 for locking on both sides of the base 3, and the locking hooks 4 are connected to the quick connector 1 by an elastic member 5. The locking hooks 4 are locked to the base 3 under the elastic force of the elastic member 5.

[0031] After replacing the quick connector 1 with a different adapter body 2, the base 3 and the quick connector 1 equipped with the adapter body 2 are docked, and the locking hooks 4 are re-locked on both sides of the base 3. The operation is convenient and time-saving.

[0032] The locking hook 4 is rotatably connected to the quick connector 1 via a hinge shaft 6. The end of the locking hook 4 that contacts the base 3 is provided with a latching joint 7 for engaging the engaging surface of the base 3. The latching joint 7 and the elastic member 5 are located on either side of the hinge shaft 6. Pressing the end of the locking hook 4 away from the latching joint 7 compresses the elastic member 5, releasing the latching joint 7 from the engaging surface of the base 3, allowing the base 3 to be separated from the quick connector 1. The elastic member 5 is a compression spring, an elastic pressing plate, or compressed rubber, preferably a compression spring.

[0033] Under normal conditions, the card joint 7 of the lock hook 4 is clamped on the clamping surface of the base 3 to achieve the limited fixation of the base 3; when it is necessary to control the separation of the base 3 and the quick connector 1, the lock hook 4 is pressed away from one end of the base 3, thereby compressing the elastic member 5. At this time, under the support of the hinge shaft 6, the card joint 7 at the connection end of the lock hook 4 and the base 3 gradually separates from the base 3, thereby releasing the limitation of the base 3; preferably, two lock hooks 4 are provided, and the two lock hooks 4 are relatively arranged on both sides of the quick connector 1. When operating, just press the two lock hooks 4 at the same time, which is very convenient to operate.

[0034] The card joint 7 is provided with a pressure-bearing inclined surface 8 that cooperates with the inclined pressure surface of the base 3 on the side close to the quick connector 1. When the base 3 and the quick connector 1 move toward each other, the inclined pressure surface of the base 3 presses against the pressure-bearing inclined surface 8 of the card joint 7, causing the card joint 7 to move away from the quick connector 1 and drive the locking hook 4 to compress the elastic member 5. The provision of the pressure-bearing inclined surface 8 facilitates the quick and smooth installation of the base 3. There is no need to press the locking hook 4 when installing the base 3, thereby improving the installation efficiency of the base 3.

[0035] One end of the elastic member 5 is inserted into the first receiving groove 9 on the inner side of the lock hook 4, where it abuts against the inner wall of the first receiving groove 9. The other end of the elastic member 5 is inserted into the second receiving groove on the outer side of the quick connector 1 and fits over the center column in the middle of the second receiving groove. The arrangement of the first receiving groove 9 and the second receiving groove ensures that the elastic member 5 remains relatively stable with the lock hook 4 and the quick connector 1, whether extended or compressed. This eliminates the need for a fixed connection between the elastic member 5, the lock hook 4, or the quick connector 1, making replacement of the elastic member 5 easy.

[0036] The end of the quick connector 1, away from the base 3, is provided with an open opening. An end cap 10, designed to protect the adapter body 2 assembled within the quick connector 1, fits within the open opening. One end of the end cap 10, which connects to the quick connector 1, is secured to the quick connector 1's snap-in interface via a resilient latch 11. The other end of the end cap 10, which connects to the quick connector 1, is bolted to the quick connector 1. The provision of end cap 10 protects the adapter body 2 within the quick connector 1, reducing damage to the adapter body 2 from external forces when not in use. It also facilitates installation and removal.

[0037] The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the same or similar parts between the various embodiments. It should be noted that those skilled in the art may make various improvements and modifications to the present application without departing from the principles of the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.

[0038] The present invention is not limited to the structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope of the present invention. The scope of the present invention is limited only by the appended claims.
