Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber processing, in particular to a U-shaped PIN needle crimping tooling. Background Art

[0002] When crimping a PIN needle into an MPO ferrule, a manual blade is often used to crimp the PIN needle so that the PIN needle is stably inserted into the MPO ferrule, realizing a reliable electrical connection between the PIN needle and the MPO ferrule.

[0003] However, when using a blade for manual crimping, the following problems are likely to occur:

[0004] 1. It is difficult to ensure that the force, angle, and position of each crimping are exactly the same with manual blade crimping, and it is easy to damage the PIN needle, resulting in unstable crimping quality. At the same time, due to the subjectivity and uncertainty of manual operation, the crimping results of different operators or the same operator at different times may vary.

[0005] 2. The crimping direction is not easy to control and needs to be adjusted repeatedly, with significantly lower speed and efficiency, which will lead to an extended production cycle and increased production costs.

[0006] 3. During the manual operation process, the operator is prone to being injured due to misoperation, such as being scratched by the blade on the finger.

[0007] 4. The labor intensity of the operator is relatively large, which is likely to cause fatigue and a decline in work efficiency. Content of the Utility Model

[0008] Aiming at the deficiencies in the prior art, the utility model provides a U-shaped PIN needle crimping tooling to solve the problems of unstable crimping quality, low efficiency, and high cost caused by using a manual blade for crimping.

[0009] To achieve the above purpose, the basic scheme of the utility model is as follows: A U-shaped PIN needle crimping tooling includes a bottom plate, and further includes:

[0010] A ferrule limiting component, which forms a jack for the vertical insertion of the MPO ferrule, and the ferrule limiting component is installed on the bottom plate;

[0011] A crimping component that can slide horizontally along the bottom plate, the crimping component is installed on the bottom plate, and the crimping component can abut against the side wall of the MPO ferrule.

[0012] The technical principle of the present utility model is as follows: during use, the jack of the ferrule limiting component can perform preliminary limiting on the MPO ferrule to be press-fitted. Then, the crimping component is controlled to horizontally slide to the jack, so that the crimping component abuts against the side wall of the MPO ferrule, further stably limiting the MPO ferrule. At this time, the U-shaped PIN can be press-fitted into the MPO ferrule with accurate positioning, realizing accurate press-fitting of the U-shaped PIN, improving the consistency of the press-fitting force, angle and position each time, improving the press-fitting accuracy and efficiency, reducing the manual operation steps during the whole process, and reducing the error probability and labor cost.

[0013] Furthermore, the ferrule limiting component includes:

[0014] A support part, which is installed on the bottom plate;

[0015] A ferrule fixing part, which is horizontally installed at the top of the support part;

[0016] A ferrule limiting part, the upper surface of which is coplanar with the upper surface of the ferrule fixing part. A first limiting groove is provided on one side of the ferrule limiting part close to the ferrule fixing part, and a second limiting groove that can be combined with the first limiting groove to form a jack is provided on one side of the ferrule fixing part close to the ferrule limiting part. The horizontal gap between the ferrule limiting part and the ferrule fixing part is adjustable.

[0017] Through the above settings, the support part can stably support the ferrule fixing part and the ferrule limiting part, making the jack formed by the combination of the first limiting groove and the second limiting groove stable, and making the limiting of the MPO ferrule stable; at the same time, since the horizontal gap between the ferrule limiting part and the ferrule fixing part is adjustable, the gap between the first limiting groove and the second limiting groove is also adjustable, so that MPO ferrules of different specifications can be inserted into the jack formed by the first limiting groove and the second limiting groove. After adjustment, the U-shaped PIN press-fitting operation can be carried out batchwise for MPO ferrules of the same specification, reducing the press-fitting operation cost and having high adjustment efficiency.

[0018] Furthermore, the support part includes:

[0019] A number of jacking support parts, the lower side of which is detachably connected to the bottom plate, and the upper side of which is detachably connected to the ferrule fixing part;

[0020] A cushion block, the lower side of which is detachably connected to the bottom plate;

[0021] A first push block, which is horizontally installed on the jacking support part, and the cushion block is supported and installed between the first push block and the bottom plate.

[0022] Through the above settings, the jacking support parts, the cushion block and the first push block can cooperate to stably support the ferrule fixing part and the ferrule limiting part.

[0023] Further, the crimping assembly includes:

[0024] A guide rail, which is horizontally and detachably mounted on the bottom plate;

[0025] A sliding part, which is slidably connected to the guide rail;

[0026] A crimping piece, which is detachably mounted on the sliding part. The crimping piece can abut against the side wall of the MPO ferrule, and the lower surface of the crimping piece is higher than or equal to the upper surface of the ferrule fixing piece.

[0027] With the above arrangement, the guide rail can guide the horizontal movement of the sliding part and the crimping piece, making the horizontal movement of the crimping piece and the limiting cooperation with the MPO ferrule stable and accurate.

[0028] Further, the sliding part includes:

[0029] A slider that can slide along the guide rail;

[0030] A slider adapter, which is detachably connected to the slider;

[0031] A second push block, which is detachably connected to the slider adapter. The side of the second push block close to the ferrule limiting component is detachably connected to the crimping piece.

[0032] With the above arrangement, the slider can slide smoothly along the guide rail, and the slider adapter and the second push block can provide stable power transmission for the sliding and can stably support the crimping piece.

[0033] Further, the crimping assembly further includes a limiting block, which is detachably mounted on the bottom plate. The limiting block is located at one end of the guide rail far from the ferrule limiting component, and the limiting block can abut against the slider adapter or the second push block.

[0034] With the above arrangement, when the crimping piece moves in the direction away from the ferrule limiting component and reaches the end of the guide rail, the slider adapter or the second push block can abut against the limiting block to prevent the crimping assembly from sliding out of the guide rail.

[0035] Further, a third limiting groove for the MPO ferrule to be inserted is vertically penetrated through one side of the crimping piece close to the ferrule limiting component.

[0036] With the above arrangement, the inner wall of the third limiting groove on the crimping piece fits with the outer wall of the MPO ferrule, realizing the abutting fixation of the MPO ferrule and further positioning of the MPO ferrule.

[0037] Further, one side of the second push block close to the ferrule limiting component extends beyond the edge of the slider adapter; or, one side of the crimping piece close to the ferrule limiting component extends beyond the edge of the second push block.

[0038] With the above settings, it is convenient for the third limiting groove of the crimping part to protrude beyond the edge of the second pushing block, and then it can accurately abut against the outer wall of the MPO ferrule for limiting, making the positioning of the MPO ferrule more stable.

Detailed Embodiments

[0041] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0042] This embodiment is basically as Figure 1 shown. An embodiment of the present invention provides a U-shaped PIN needle crimping tooling, which includes a base plate 10, a ferrule limiting assembly, and a crimping assembly that can slide horizontally along the base plate 10. The ferrule limiting assembly forms a jack 40 for the vertical insertion of the MPO ferrule. Both the ferrule limiting assembly and the crimping assembly are installed on the base plate 10.

[0043] As Figure 1 shown, the ferrule limiting assembly includes a support part, a ferrule fixing part 20, and a ferrule limiting part 30. The support part includes two lifting support parts 50, a cushion block 501, and a first pushing block 502. The lower side of the lifting support part 50 is detachably connected to the base plate 10 by screws, and the upper side of the lifting support part 50 is detachably connected to the ferrule fixing part 20 by screws. The ferrule fixing part 20 is horizontally installed at the top of the lifting support part 50; the lower side of the cushion block 501 is detachably connected to the base plate 10 by screws; the first pushing block 502 is horizontally installed on the lifting support part 50, and the cushion block 501 is supported and installed between the first pushing block 502 and the base plate 10; at the same time, the upper surface of the ferrule limiting part 30 is coplanar with the upper surface of the ferrule fixing part 20. A first limiting groove 301 is provided on the left side of the ferrule limiting part 30, and a second limiting groove 201 that can be combined with the first limiting groove 301 to form the jack 40 is provided on the right side of the ferrule fixing part 20. A bolt is horizontally installed between the ferrule limiting part 30 and the ferrule fixing part 20 to realize the adjustable horizontal gap between the ferrule limiting part 30 and the ferrule fixing part 20.

[0044] As Figure 1As shown in the figure, the crimping assembly includes a guide rail 60, a sliding part, a limit block 601, and a crimping part 70. The sliding part includes a slider 801 that can slide along the guide rail 60, a slider 801 adapter, and a second push block 803. The slider 801 adapter is detachably connected to the slider 801 by screws; the second push block 803 is detachably connected to the slider 801 adapter by screws, and the side of the second push block 803 close to the ferrule limiting assembly is detachably connected to the crimping part 70 by screws; the guide rail 60 is horizontally detachably mounted on the bottom plate 10 by screws; the crimping part 70 is detachably mounted on the sliding part, the crimping part 70 can abut against the side wall of the MPO ferrule, the lower surface of the crimping part 70 is higher than or equal to the upper surface of the ferrule fixing part 20, and a third limiting groove 701 through which the MPO ferrule can be inserted is vertically penetrated on the left side of the crimping part 70; at the same time, the limit block 601 is detachably mounted on the bottom plate 10, the limit block 601 is located at one end of the guide rail 60 away from the ferrule limiting assembly, and the limit block 601 can abut against the slider 801 adapter or the second push block 803.

[0045] In addition, as Figure 1 shown, the side of the second push block 803 close to the ferrule limiting assembly extends beyond the edge of the slider 801 adapter; alternatively, the side of the crimping part 70 close to the ferrule limiting assembly extends beyond the edge of the second push block 803.

[0046] When the U-shaped PIN needle crimping tooling in this embodiment is in use, first adjust the bolt between the ferrule limiting part 30 and the ferrule fixing part 20 according to the specifications of the MPO ferrule, so that the horizontal gap between the ferrule limiting part 30 and the ferrule fixing part 20 is adjusted to just the width enough for the MPO ferrule to be vertically inserted. The adjustment of the gap here enables MPO ferrules of different specifications to be inserted into the jack 40 formed by the first limiting groove 301 and the second limiting groove 201. After the adjustment, the U-shaped PIN needles can be batch-pressed onto the MPO ferrules of the same specification.

[0047] Then control the crimping assembly to move along the guide rail 60 towards the ferrule limiting assembly. During this process, the slider 801 adapter or the second push block 803 is pushed towards the ferrule limiting assembly. At this time, the slider 801 slides along the guide rail 60 synchronously. The guide rail 60 guides the horizontal sliding of the crimping part 70. When the crimping part 70 moves to the jack 40, the inner wall of the third limiting groove 701 on the crimping part 70 fits against the outer wall of the MPO ferrule, realizing the abutting and fixing of the MPO ferrule and further positioning the MPO ferrule. At this time, the U-shaped PIN needle can be pressed into the MPO ferrule with accurate positioning, realizing the accurate pressing of the U-shaped PIN needle, improving the consistency of the pressing force, angle, and position each time, improving the pressing accuracy and efficiency, reducing the manual operation steps during the whole process, and reducing the error probability and labor cost.
