Description

Technical Field

[0001] This utility model relates to the field of capillary processing, and in particular to a capillary constraint device. Background Technology

[0002] When processing capillary ferrules in optical fiber communication, a glass slide needs to be attached to the front of the capillary ferrule. The purpose of this is to fix the position of the capillary and ensure that it does not shift during the subsequent ferrule process, and it also serves to isolate contamination.

[0003] Before attaching a glass slide to a capillary, the capillary needs to be constrained and fixed. Currently, a method similar to a "clamp" is commonly used to restrict the front-to-back direction and the direction of twisting of the capillary. This method mainly relies on pressure to restrict the capillary. However, since the capillary itself is a glass product with a very low coefficient of friction, it is very easy to move, which affects the quality of glass slide attachment during the process of attaching the glass slide. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a capillary constraint device to solve the technical problem that the capillary is not stable when constrained and fixed by pressure in the existing technology, and the capillary moves during the glass slide application process, which affects the accurate application of the glass slide.

[0005] According to an embodiment of the present invention, a capillary constraint device includes a support base and a limiting plate. The top of the support base is detachably provided with a positioning plate. A plurality of slots are equally spaced on one side of the positioning plate. The top of the support base is provided with receiving holes corresponding to the slots. The size of the receiving holes is smaller than the size of the slots and is located directly below the slots. A receiving groove communicating with the outside is provided on the side of the receiving holes away from the support base. The limiting plate is detachably provided on the top of the support base and located on one side of the slots. The limiting plate is used to restrict the capillary from tilting out of the slots.

[0006] Compared with the prior art, this utility model has the following advantages: By detachably setting a positioning plate that can be adapted to different models on the support base, the slot of the positioning plate and the receiving hole on the support base form a step to support the end of the capillary tube. After the capillary tube is placed in the slot, the limiting plate limits and constrains the capillary tube in the slot, keeping the capillary tube in a vertically upward state. Due to the support of the step on the capillary tube and the limitation of the limiting plate, the multiple degrees of freedom of the capillary tube are restricted, and it is impossible to make horizontal or vertical displacement. The capillary tube is stably constrained in the slot, thereby ensuring the yield of the product after the staff attaches the glass slide to the capillary tube.

[0007] Furthermore, the top of the support base has mounting holes, each containing a magnet, and the limiting plate has magnetic material.

[0008] Furthermore, each slot has a square cross-section.

[0009] Furthermore, each slot on the positioning plate has a symmetrical arc groove on the side opposite to the limiting plate.

[0010] Furthermore, each receiving hole has an arc-shaped transition surface at its top.

[0011] Furthermore, the positioning plate is bolted to the support base.

[0012] Furthermore, the support base has a concave structure. Attached Figure Description

[0015] The present invention will be further described in detail below through specific embodiments: like Figures 1-3As shown, a capillary constraint device includes a support base 1 and a limiting plate 6. The top of the support base 1 is detachably provided with a positioning plate 2. A plurality of slots 3 are equally spaced on one side of the positioning plate 2. The top of the support base 1 is provided with receiving holes 4 corresponding to the slots 3 one by one. The size of the receiving holes 4 is smaller than the size of the slots 3 and is located directly below the slots 3. A receiving groove 5 communicating with the outside is provided on the side of the receiving holes 4 away from the support base 1. The limiting plate 6 is detachably provided on the top of the support base 1 and located on one side of the slots 3. The limiting plate 6 is used to restrict the capillary from tilting out of the slots 3. Specifically, slot 3 has an opening on one side that communicates with the outside. The limiting plate 6 is located directly above the receiving groove 5. The receiving groove 5 is connected to the receiving hole 4. When attaching glass slides to the capillary, one end of the capillary is connected to an optical fiber. The cross-section of the optical fiber is smaller than the cross-section of the capillary ferrule. When the capillary is installed on the support base 1, the optical fiber on the capillary passes through the receiving groove 5 and enters the receiving hole 4. At this time, the capillary is above the receiving hole 4 and located in the slot 3. The step formed by the slot 3 and the receiving hole 4 supports the capillary. After multiple capillary tubes are placed into the corresponding slot 3 one by one, the limiting plate 6 limits them in the slot 3, so that the capillary is in a vertical upward state and will not tip over. This device features a detachable positioning plate 2 on the top of the support base 1. The slots 3 on the positioning plate 2 correspond one-to-one with the receiving holes 4 of the support base 1, forming a step for vertically placing the capillary. When mounting glass slides onto different types of capillary, only the positioning plate 2 needs to be replaced. The shape and size of the slots 3 on different positioning plates 2 correspond to different capillary models. A limiting plate 6 limits and supports one side of the capillary, ensuring that the capillary can only move upwards. Under gravity, the capillary will not move upwards. After the limiting plate 6 confines the capillary within the slot 3, there is no tendency for relative movement between the two, thus stably constraining and fixing the capillary. Furthermore, there is no tendency for relative movement between the capillary and the positioning plate 2 and the limiting plate 6, preventing scratches on the capillary and effectively ensuring a high yield rate.

[0016] like Figure 3 and Figure 4 As shown, the top of the support base 1 is provided with mounting holes 7, each mounting hole 7 is provided with a magnet, and the limiting plate 6 is provided with magnetic material. Specifically, magnetic material can be installed on the limiting plate 6 at the position corresponding to the mounting hole 7, or the limiting plate 6 can be made entirely of magnetic material. The magnetic material can be selected from the prior art, such as neodymium iron boron. The limiting plate 6 and the support base 1 are detachably connected by magnetic attraction, which facilitates the release and restraint of the capillary tube in the slot 3 by the worker.

[0017] like Figure 4 and Figure 5As shown, furthermore, the cross-section of each slot 3 is square. Specifically, the capillary insert is mostly square in structure, and the slot 3 is made into a square structure that fits the capillary insert. When the capillary is placed into the receiving space formed by the slot 3 of the positioning plate 2 and the limiting plate 6, the capillary cannot rotate, thereby ensuring the stable constraint of the capillary by this device.

[0018] like Figure 4 and Figure 5 As shown, furthermore, each slot 3 of the positioning plate 2 has a symmetrically formed arc groove 8 on the side opposite to the limiting plate 6. When the capillary is inserted into the slot 3, the arc groove 8 can act as a "flared mouth" guide, reducing frictional resistance during insertion and preventing jamming or scratching of the capillary surface. In particular, the arc groove 8 forms a clearance, preventing pressure on the edge of the capillary, which could cause the thinner part of the edge to break under pressure.

[0019] like Figure 4 and Figure 5 As shown, each receiving hole 4 is further provided with an arc-shaped transition surface 9 at its top. The arc-shaped transition surface 9 serves to smoothly transition the optical fiber connected to the capillary tube, preventing the optical fiber connected to the capillary tube from being scratched when it moves within the receiving hole 4 during installation and removal of the capillary tube.

[0020] Furthermore, the positioning plate 2 is bolted to the support base 1. The positioning plate 2 and the support base 1 are connected in a detachable manner by bolts. When attaching glass slides to different types of capillaries, the positioning plate 2 can be replaced with the corresponding positioning plate 2, so that the slot 3 on the positioning plate 2 is adapted to the size of the capillary.

[0021] like Figure 1 As shown, the support base 1 further has a concave structure. Specifically, the concave support base 1 has a groove, the square shape of which is consistent with the direction of the receiving groove 5. The optical fiber connected to the capillary can be accommodated in this area for temporary storage and protection of the optical fiber.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
