Description

Technical Field

[0001] The utility model relates to an optical fiber connector, in particular to an optical fiber connector plugging and unplugging mechanism. Background Art

[0002] Optical fiber is a light transmission tool. In order for optical fiber to be connected to various electronic devices and the information it transmits can be used by these electronic devices, a connector is required as an intermediary between the optical fiber and the electronic device to achieve the connection purpose.

[0003] A typical fiber optic connector consists of a female adapter that matches a male fiber optic connector. The female adapter is installed in the electronic device. When the male fiber optic connector is inserted into the female adapter, a connection is established, thereby achieving the purpose of fastening and data transmission.

[0004] With the expansion of computing centers and the rapid increase in the number of devices that require computing, the space for each fiber optic connector has become smaller. When replacing one set of fiber optic connectors (a pair is a group) in a cabinet with limited space, the hand cannot properly press the elastic arm on the male fiber optic connector to disengage the elastic arm from the female adapter, making it difficult to remove the cable and even damaging the entire cable and other cables. The amount of wiring is also reduced due to space constraints.

[0005] Currently, the market uses a pull handle method to solve the above problem. The male fiber optic connector is pulled by extending the distance. However, the pull handle structure itself is only a single structure and is located above the male fiber optic connector. The only connection point with the entire male fiber optic connector is the elastic arm at the front end of the male fiber optic connector. Therefore, to avoid the pull handle structure being too large, this thinner method is adopted. As a result, prolonged use or incorrect pulling method can easily lead to deformation or breakage. Therefore, how to solve the problems of the conventional structure is an issue that relevant industry players must consider. Utility Model Content

[0008] Preferably, the housing defines a housing opening for inserting the base and a receiving space for accommodating the base.

[0009] Preferably, the housing is defined on both sides by a limiting opening, the limiting openings corresponding to the limiting parts formed on both sides of the base, and the limiting openings are used to limit the moving range of the limiting parts to control the moving position of the housing corresponding to the base.

DETAILED DESCRIPTION

[0026] See also Figure 1 and Figure 2The figures are a perspective schematic diagram and an exploded perspective schematic diagram of a preferred embodiment of the present invention. This invention is a fiber optic connector plugging and unplugging mechanism, primarily comprising: a plurality of LC fiber optic connectors 1, a base 2, and a housing 3. Each LC fiber optic connector 1 is adjacently disposed within a mounting space 20 within the base 2. Each LC fiber optic connector 1 comprises a housing 10, an optical fiber assembly 12, and an optical fiber transmission line 14. The optical fiber transmission line 14 connected to the optical fiber assembly 12 is mounted within a receiving groove 22 of the housing 10. The housing 3 is then mounted onto the base 2. The optical fiber assembly 12 mentioned above mainly includes a pin, a core tube, a spring and a sleeve. The core tube is made of ceramic material. The core tube is used to cover the optical fiber and make the optical fiber cut flush with the core hole. The pin is located at one end of the core tube, and one end of the sleeve is connected to the other end of the core tube. The other end of the sleeve is connected to the optical fiber transmission line 14 (represented by a single imaginary image). The sleeve is fixed at the rear end of the base 2, and the spring is connected to the other end of the core tube. The spring is placed in the sleeve. One end of the spring abuts the core tube, and the other end of the spring abuts the sleeve. The spring is used to give the core tube a buffering effect.

[0027] The aforementioned shell 10 has an extension arm 100 extending from one end of the top surface toward the other end, and has a snap portion 102 connecting the extension arm 100, and a connecting portion 104 extending from the snap portion 102, wherein the connecting portion 104 forms an actuating space 106, and an inclined inner wall 1060 is defined in the actuating space 106. The inclined inner wall 1060 defines a first positioning point 1062 on the side adjacent to the snap portion 102, and a second positioning point 1064 on the side away from the snap portion 102.

[0028] The housing 3 is mounted on the base 2, and a sliding member 30 is provided on the top surface of the housing 3. The sliding member 30 includes a support member 300, a first rod 302, and a second rod 304. The support member 300 extends from the top surface of the housing 3, and the first rod 302 and the second rod 304 are respectively located on both sides of the support member 300. The first rod 302 is placed in the actuating space 106 of one of the LC fiber optic connectors 1, and the second rod 304 is placed in the actuating space 106 of the other LC fiber optic connector 1. The space 106 can move the base 2 laterally by pulling the sleeve 3, so that the first rod 302 and the second rod 304 can move between the first positioning point 1062 and the second positioning point 1064 by abutting against the inclined inner wall 1060, and change the action state of the extension arm 100. The height of the aforementioned support member 300 can enable the first rod 302 and the second rod 304 to maintain the same height when located at the first positioning point 1062 without generating abutting pressure on the inclined inner wall 1060.

[0029] The aforementioned housing 3 defines a housing opening 32 for inserting the base 2 and a receiving space 34 for accommodating the base 2. Limit openings 36 are defined on both sides of the housing 3. The limit openings 36 correspond to the limit portions 24 formed on both sides of the base 2. Each limit opening 36 is used to limit the movement range of the limit portion 24 to control the movement position of the housing 3 corresponding to the base 2.

[0030] For reference Figure 3 、 Figure 4 and Figure 5 The figure shows a top view of the unassembled LC fiber optic connectors and adapters of the present invention, a cross-sectional view of the assembled adapters, and a cross-sectional view of the sleeve being pulled back to cause the extension arm to move downward and detach from the adapter. The present invention primarily assembles a pair of LC fiber optic connectors 1 (two) to a base 2, then places the sleeve 3 over the base 2. During use, the sleeve 3 can be directly inserted into the insertion channel 40 of the adapter 4. Once inserted, the latching portion 102 on each LC fiber optic connector 1 latches with the latching groove 42 of the adapter 4 located in the insertion channel 40, preventing the LC fiber optic connector 1 from detaching from the adapter 4 and providing stable signal transmission.

[0031] In the above description, when the assembly of each LC fiber optic connector 1 and the adapter 4 is completed, the first rod 302 and the second rod 304 on each LC fiber optic connector 1 are located at the first positioning point 1062, and the locking portion 102 is locked and positioned in the locking groove 42, and the limiting portion 24 does not interfere with the limiting opening 36. At the same time, the extension arm 100 remains in a stationary state, that is, the extension arm 100 is away from the top surface of the housing 10 according to the locked state, and the height of the support member 300 located on the sleeve 3 can ensure that the first rod 302 and the second rod 304 maintain the same height when located at the first positioning point 1062 without generating any abutting pressure on the inclined inner wall 1060.

[0032] When each LC fiber optic connector 1 is to be removed from the adapter 4, the housing 3 on the base 2 is pulled toward the reverse position of the LC fiber optic connector 1. At this time, the first rod 302 and the second rod 304 located in the actuating space 106 of the LC fiber optic connector 1 will move laterally relative to the base 2 by pulling the housing 3. Then, they will move from the first positioning point 1062 to the second positioning point 1064 by abutting against the inclined inner wall 1060. The latch portion 102 will disengage from the latch groove 42 and enter the unlocked state. The limiting portion 24 will interfere with the limiting opening 36 to prevent the housing 3 from being removed from the base 2. In the unlocked state, the extension arm 100 is positioned close to the top surface of the housing 10 according to the unlocked state.

[0033] As can be seen from the above, the present invention mainly moves the base 2 laterally by pulling the housing 3, so that the first rod 302 and the second rod 304 move between the first positioning point 1062 and the second positioning point 1064 by abutting against the inclined inner wall 1060, and changes the action state of the extension arm 100. When the LC fiber optic connector 1 is plugged into the adapter 4, the housing 3 is away from the adapter 4. Therefore, even if the adapters 4 are arranged closely, there is no problem of narrow space between the housings 3 of adjacent groups of LC fiber optic connectors 1. The housing 3 can still be easily pulled, and then each group of fiber optic connectors 1 can be smoothly removed from the adapter 4.
