Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically to a single-fiber connector dispensing and curing fixing fixture. Background Technology

[0002] In the field of fiber optic communication technology, the dispensing and curing process of single-fiber connectors is a crucial step in ensuring precise mating between fiber optic connectors and optical devices. In existing technologies, typical dispensing and curing fixtures usually employ a slotted structure design, i.e., fixing the connector and the optical device bonded and cured with the dispensed connector by creating a groove (such as a square groove) in the fixture base. However, such traditional fixtures have the following significant drawbacks in practical applications: Existing fixtures rely solely on the physical boundaries of the groove to constrain the rotation angle of the components. However, to accommodate the dimensional tolerances of the parts, the groove dimensions are generally too large. While this "loose fit" strategy can accommodate the dimensional tolerances of the parts, it significantly weakens the groove's ability to restrict the axial and radial directions of the components. Especially during the bonding and curing process, both the upper and lower components have considerable axial and radial movement space, making precise positioning difficult. In production environments with insufficient precision control, these defects can easily lead to axial / radial misalignment between the connector and the optical components. Furthermore, this misalignment problem can propagate along the process chain, ultimately resulting in substandard optical performance of the final product and severely impacting the yield rate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a single-fiber connector dispensing and curing fixture to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A single fiber connector dispensing and curing fixing fixture includes a base, an inverted L-shaped base, and a clamping member; the lower end face of the vertical plate of the base is connected to the upper end face of the base, and a number of square grooves are horizontally spaced on the first horizontal plate of the base. The clamping member is set on the front side of the vertical plate of the base, and the clamping member includes a number of C-shaped elastic clips, which are horizontally arranged one-to-one below the number of square grooves.

[0005] The beneficial effects of this utility model are as follows: During use, the lower and upper parts of the connector are first inserted into the C-shaped elastic clip and the square groove, respectively. Then, adhesive is applied to the top of the connector. After the adhesive is applied, the optical device is inserted from the top of the square groove to achieve adhesion and curing between the optical device and the connector. Because a C-shaped elastic clip is added to the lower end of the square groove, the C-shaped elastic clip has a certain elasticity, which can accommodate the dimensional tolerances of the parts and can achieve the fastening and fixing of the parts. During the adhesion and curing process of the connector and the optical device, the C-shaped elastic clip fixes the connector axially and radially from the bottom, thereby improving the accuracy of adhesion and curing between the optical device and the connector.

[0007] Furthermore, the clamping component also includes a connecting rod, and several C-shaped elastic clamps are respectively connected to the connecting rod. The connecting rod is detachably connected to the front side wall of the vertical plate.

[0009] Furthermore, limit baffles are provided at both ends of the connecting rod, and the distance between the two limit baffles is consistent with the width of the vertical plate.

[0010] Furthermore, several bases and clamping components are provided, and each base is detachably connected to the base.

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] like Figures 1-4 As shown in Embodiment 1, a single-fiber connector dispensing and curing fixture includes a base 1, an inverted L-shaped base 2, and a clamping member 3. The lower end face of the vertical plate 21 of the base 2 is connected to the upper end face of the base 1. A plurality of square grooves 221 are longitudinally formed on the first horizontal plate 22 of the base 2. The clamping member 3 is disposed on the front side of the vertical plate 21 of the base 2. The clamping member 3 includes a plurality of C-shaped elastic clips 31 arranged at intervals along the width direction of the vertical plate 21. The plurality of C-shaped elastic clips 31 are arranged horizontally below the plurality of square grooves 221 in a corresponding manner.

[0017] During use, the lower and upper parts of the connector 4 are first inserted into the C-shaped elastic clip 31 and the square groove 221 respectively. Then, glue is applied to the top of the connector 4. After the glue is applied, the optical device is inserted from the upper part of the square groove 221 to achieve adhesion and curing between the optical device and the connector 4. Since the C-shaped elastic clip 31 is added to the lower end of the square groove 221, the C-shaped elastic clip 31 has a certain elasticity, which can accommodate the dimensional tolerances of the parts and can achieve fastening and fixing of the parts. During the adhesion and curing process of the connector 4 and the optical device, the C-shaped elastic clip 31 fixes the connector 4 axially and radially from the bottom, thereby improving the accuracy of adhesion and curing between the optical device and the connector 4.

[0018] In practice, the thickness of the C-shaped elastic clip 31 matches the spacing between the two angle limiting square plates of the connector 4. The C-shaped elastic clip 31 is inserted into the fixing slot between the two angle limiting square plates, further improving the axial fixation of the connector 4. The C-shaped elastic clip 31 is a copper spring structure, which is more durable.

[0019] Example 2 is a further improvement based on Example 1, and its details are as follows: The clamping member 3 also includes a connecting rod 32, and several C-shaped elastic clamps 31 are respectively connected to the front side wall of the connecting rod 32. The connecting rod 32 is detachably connected to the front side wall of the vertical plate 21.

[0020] The C-shaped elastic clip 31 is a consumable part. During long-term use, its clamping performance is easily reduced due to metal fatigue. By making it detachable, only the C-shaped elastic clip 31 can be replaced according to the usage, without having to replace the entire fixing fixture, which can effectively reduce costs. In addition, by setting several C-shaped elastic clips 31 on the connecting rod 32, it is not necessary to replace each C-shaped elastic clip 31 individually, which can greatly improve the replacement efficiency of the C-shaped elastic clip 31.

[0021] Example 3 is a further improvement based on Example 2, and its details are as follows: It also includes a support plate 23 and a pressure plate 24; an embedding groove 211 is provided on the vertical plate 21, and the support plate 23 is detachably installed in the embedding groove 211; multiple pressure plates 24 are provided and are spaced apart on the upper end of the front side wall of the support plate 23; a connecting rod 32 is provided on the top of the support plate 23 and is located between the pressure plate 24 and the vertical plate 21; the pressure plate 24 and the C-shaped elastic clamp 31 are offset.

[0022] The support plate 23 and the pressure plate 24 can improve the stability of the clamping part 3 during installation; in specific implementation, the support plate 23 is detachably connected to the vertical plate 21 by bolts.

[0023] Example 4 is a further improvement on Example 3, and its details are as follows: Both ends of the connecting rod 32 are provided with limit baffles 33, and the distance between the two limit baffles 33 is the same as the width of the vertical plate 21. This serves to limit the movement, facilitates quick installation and alignment, and ensures that the square groove 221 corresponds one-to-one with the C-shaped elastic clip 31.

[0024] Example 5 is a further improvement based on Example 1, and its details are as follows: Several bases 2 and clamping components 3 are provided, and each base 2 is detachably connected to the base 1. The appropriate number of bases 2 and clamping components 3 can be used according to actual production needs.

[0025] Example 6 is a further improvement on Example 5, and its details are as follows: It also includes at least two insertion rods 25, a slot 212 is provided through the vertical plate 21 along its height direction, and an insertion hole 11 is provided on the base 1. One end of the insertion rod 25 is detachably connected to the insertion hole 11, and the other end extends into the slot 212.

[0026] This technical solution enables rapid expansion of the base 2 and the clamping member 3. In specific implementation, the insertion hole 11 is a threaded hole, and the insertion rod 25 includes a screw and a smooth rod connected to the upper end of the screw. The screw is threadedly engaged with the insertion hole 11, and the smooth rod is inserted into the slot 212.

[0027] Example 7 is a further improvement on Example 6, and its details are as follows: A second horizontal plate 26 is also provided at the bottom of the vertical plate 21. The first horizontal plate 22, the vertical plate 21, and the second horizontal plate 26 form a C-shaped structure. The second horizontal plate 26 is in contact with the upper end surface of the base 2. This makes the base 2 more stable and reduces the risk of the insertion rod 25 bending under stress.
