Description

Technical Field

[0001] The utility model relates to the technical field of MPO connectors, in particular to an anti-loosening card block of an MPO connector. Background Art

[0002] The MPO connector includes: an outer shell, an inner shell and a jumper 840. The inner shell is sleeved on the jumper 840, and the outer shell is movably sleeved on the inner shell. The rear ends of the outer shell and the inner shell both have protrusions. Usually, the width of the protrusion at the rear end of the inner shell is smaller than the width of the protrusion at the rear end of the outer shell. When the outer shell moves along its length on the inner shell, a slide groove will be formed between the rear ends of the outer shell and the rear ends of the inner shell. When the MPO connector is inserted into the MPO adapter of the optical module, the outer shell of the MPO connector will block the buckle of the MPO adapter to prevent the buckle of the MPO adapter from springing outward, so as not to cause abnormal position of the jumper and affect performance. However, in actual use, especially when the jumper is relatively long, due to the weight of the jumper, it is easy to cause the buckle of the MPO adapter to loosen from the MPO connector. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an anti-loosening card block for an MPO connector to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model provides a technical solution to the above technical problem as follows: an anti-loosening card block for an MPO connector, comprising: a structural block, a first card slot for accommodating a protrusion at the rear end of an inner shell in an MPO connector is provided on the lower surface of the structural block in an area close to the front end thereof, and a second card slot is provided on the lower surface of the structural block that penetrates the front end surface thereof and is connected to the first card slot; the length of the area on the structural block where the second card slot is provided is smaller than the length of the slide slot in the MPO connector; the width of the second card slot is larger than the width of the inner shell in the MPO connector in the slide slot area, and smaller than the width of the protrusion at the rear end of the inner shell.

[0005] The beneficial effects of the utility model are:

[0006] During use, the first card slot of the structural block is stuck on the rear end protrusion of the inner shell in the MPO connector, and the area where the second card slot is opened in the structural block is stuck in the slide groove formed between the rear end of the outer shell and the rear end of the inner shell in the MPO connector, so that the outer shell can be prevented from retreating relative to the inner shell. At this time, even if the jumper has a certain weight, it will not cause the MPO adapter's buckle and the connector to loosen. The MPO connector anti-loosening card block does not require structural improvement of the MPO connector, and can be applied to existing MPO connectors. The MPO connector anti-loosening card block can be removed from the MPO connector, so it can be used on the next MPO connector, that is, it can be reused.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the structural block has two first card slots and two second card slots arranged side by side; the center distance between the two first card slots and the two second card slots is the same as the center distance between the two MPO connectors plugged into the optical module.

[0009] A further beneficial effect of the above is that when two MPO connectors are plugged into the optical module, the MPO connector anti-loosening card block can still be used.

[0010] Furthermore, a third groove is formed on the lower surface of the structural block, which passes through the rear end surface thereof and is connected to the second card slot. The third groove is used to accommodate a jumper wire of the MPO connector.

[0011] A further beneficial effect of adopting the above method is that the structural block can be better adapted to the MPO connector.

[0012] Furthermore, the first slot passes through the upper surface of the structural block.

[0013] A further beneficial effect of the above method is that it is possible to observe through the upper opening of the first card slot whether the MPO connector anti-loosening card block is assembled in place.

[0014] Furthermore, a clamping position is provided on the structural block for the structural block to be clamped between two arms of the U-shaped handle in the optical module.

[0015] A further beneficial effect of the above method is that the anti-loosening card block of the MPO connector can be prevented from falling off the U-shaped handle in the optical module.

[0016] Furthermore, the clamping positions are two protrusions located on both sides of the structural block and distributed along the length direction of the structural block. When the structural block is clamped between the two arms of the U-shaped handle in the optical module, the upper surfaces of the two protrusions are attached to the lower surface of the structural block.

[0017] Furthermore, a notch is provided on the structural block starting from the area near the second slot and penetrating through the upper and lower surfaces and the rear end surface thereof, and the areas on both sides of the structural block not covered by the notch form hand gripping positions.

[0018] The above-mentioned further beneficial effect is that when the MPO connector anti-loosening card block needs to be removed, it can be removed by prying the hand position, and in addition, the notch does not affect the function of manually pulling the optical module pull ring.

[0019] Furthermore, the lower surface of the protrusion is an inclined surface that slopes downward from the outside to the inside.

[0020] Furthermore, the lower edge of the protrusion is flush with the lower surface of the structural block. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] Example 1

[0030] like Figure 1 to Figure 5 As shown, an MPO connector anti-loosening card block includes: a structural block 1, a first card slot 2 is provided on the lower surface of the structural block 1 in an area near the front end thereof, and when the structural block 1 is subsequently mated with the MPO connector 8, the first card slot 2 of the structural block 1 is used to accommodate the rear end protrusion 821 of the inner shell 820 of the MPO connector 8;

[0031] The lower surface of the structural block 1 is provided with a second card slot 3, which not only penetrates the front end surface of the structural block 1, but also communicates with the first card slot 2. The length of the area where the second card slot 3 is provided on the structural block 1 is smaller than the length of the slide slot 830 in the MPO connector 8. This limitation ensures that when the structural block 1 is subsequently mated with the MPO connector 8, the area where the second card slot 3 is provided on the structural block 1 can be inserted into the slide slot 830 formed between the rear end of the outer shell 810 and the rear end of the inner shell 820 in the MPO connector 8.

[0032] The width of the second card slot 3 is larger than the width of the inner shell 820 in the MPO connector 8 in the area of ​​the slide slot 830, and the width of the second card slot 3 is smaller than the width of the protrusion 821 at the rear end of the inner shell 820. This limitation ensures that when the subsequent structural block 1 is stuck in the area of ​​the inner shell 820 in the slide slot 830, the outer shell 810 can be prevented from retreating relative to the inner shell 820;

[0033] During use, the first card slot 2 of the structural block 1 is stuck on the rear end protrusion 821 of the inner shell 820 in the MPO connector 8, and the area of ​​the structural block 1 where the second card slot 3 is opened is stuck in the slide groove 830 formed between the rear end of the outer shell 810 and the rear end of the inner shell 820 in the MPO connector 8, so as to prevent the outer shell 810 from retreating relative to the inner shell 820. At this time, even if the jumper 840 has a certain weight, it will not cause the MPO adapter buckle and the MPO connector 8 to loosen. The MPO connector anti-loosening card block does not need to make structural improvements to the MPO connector 8, and can be applied to the existing MPO connector 8. The MPO connector anti-loosening card block can be removed from the MPO connector 8, so it can be used on the next MPO connector 8, that is, it can be reused.

[0034] Example 2

[0035] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0036] The structural block 1 has two first card slots 2 and two second card slots 3 distributed side by side, and the center distance between the two first card slots 2 is the same as the center distance between the two MPO connectors 8 plugged into the optical module 9, and the center distance between the two second card slots 3 is the same as the center distance between the two MPO connectors 8 plugged into the optical module 9. When two MPO connectors 8 are plugged into the optical module 9, the MPO connector anti-loosening card block can still be applied.

[0037] Example 3

[0039] A third groove 5 is provided on the lower surface of the structural block 1. The third groove 5 not only passes through the rear end surface of the structural block 1, but is also connected to the second card slot 3. The third groove 5 is used to accommodate the jumper wire 840 of the MPO connector 8 so that the structural block 1 can better adapt to the MPO connector 8.

[0040] Example 4

[0041] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on any one of Embodiments 1 to 3, and the details are as follows:

[0042] The first card slot 2 passes through the upper surface of the structural block 1 . At this time, through the upper opening of the first card slot 2 , it can be observed whether the MPO connector anti-loosening card block is assembled in place.

[0043] Example 5

[0044] like Figure 1 to Figure 5 As shown, this embodiment is a further improvement on any one of Embodiments 1 to 4, and the details are as follows:

[0045] The structural block 1 is provided with a clamping position 4 for allowing the structural block 1 to be clamped between the two arms of the U-shaped handle 910 in the optical module 9.

[0046] Example 6

[0047] like Figure 1 to Figure 5 As shown, this embodiment is a further improvement on the basis of Embodiment 5, and the details are as follows:

[0048] The clamping position 4 is two protrusions located on both sides of the structural block 1 and distributed along the length direction of the structural block 1. When the structural block 1 is clamped between the two arms of the U-shaped handle 910 in the optical module 9, the upper surfaces of the two protrusions are attached to the lower surface of the structural block 1. The structure is simple and can allow the MPO connector anti-loosening clamping block to be stably clamped between the two arms of the U-shaped handle 910 in the optical module 9.

[0049] Example 7

[0050] like Figure 1 to Figure 5 As shown, this embodiment is a further improvement on the basis of Embodiment 5 or 6, and the details are as follows:

[0051] A notch 6 is provided on the structural block 1, and the notch 6 does not affect the function of manually pulling the optical module pull ring, wherein the notch 6 extends from the area close to the second card slot 3 and penetrates the rear end surface of the structural block 1. In addition, the notch 6 also penetrates the upper and lower surfaces of the structural block 1, and the areas on both sides of the structural block 1 not covered by the notch 6 form hand-gripping positions 7. When the MPO connector anti-loosening card block needs to be removed, it can be removed by prying the hand-gripping positions 7.
