Description

Technical Field

[0001] This utility model belongs to the field of connector auxiliary tooling technology, specifically relating to an auxiliary tooling for an airtight connector. Background Technology

[0002] The core component of a ceramic core connector is the ceramic ferrule, a small cylinder made of high-precision special ceramic materials (such as nano-zirconia) through a series of processes. It is a key component in fiber optic connectors for realizing optical signal transmission.

[0003] The existing CN218040146U discloses an auxiliary tooling for a gas-tight connector, comprising: a vacuum fixture for generating a vacuum, the vacuum fixture including a fixture top cover and a fixture housing, the fixture top cover having a socket for connecting to a plug, the fixture housing having a vacuum generating cavity, and the fixture top cover sealing the vacuum generating cavity; a vacuum machine communicating with the vacuum generating cavity and generating a vacuum within the vacuum generating cavity; and a glue dispensing machine for sealing the connector plug.

[0004] When using this vacuum fixture, if it is necessary to extract the fixture shell to a vacuum state, it is only sealed with a single sealing ring, which is not very effective. At the same time, it is impossible to monitor the defoaming status and the internal vacuum level inside the fixture shell in real time, making it not very practical. Summary of the Invention

[0005] This utility model provides an auxiliary tooling for an airtight connector, which aims to solve the problems of existing vacuum fixtures, which, when used, require the fixture shell to be evacuated to a vacuum state, rely solely on a single sealing ring for sealing, resulting in poor sealing performance. Furthermore, they cannot monitor the defoaming status and internal vacuum level of the fixture shell in real time, thus limiting their practicality.

[0006] This utility model provides an auxiliary tooling for an airtight connector, including a vacuum fixture. The vacuum fixture has a vacuum machine and a glue injection machine on both sides. The vacuum fixture has a fixture plate inside. The vacuum fixture is divided into a shell and a fixture cover. Both the shell and the fixture cover are provided with a sealing mechanism. A vacuum gauge is installed on the fixture cover. The vacuum gauge is connected to the inside of the shell. The wall of the shell is provided with transparent glass.

[0007] Furthermore, the outer shell has an upward-opening cylindrical structure, and a slot is provided on the top wall of the outer shell. A first groove is provided on the top wall of the outer shell on the outer side and the inner side of the slot, respectively.

[0008] By adopting the above technical solution, the outer shell and the fixture cover can be threaded together via slots and inserts.

[0009] Furthermore, the fixture cover has a cylindrical structure with the opening facing downwards, and an insert plate is fixedly connected to the bottom wall of the fixture cover. The bottom wall of the fixture cover is provided with second grooves on the outer and inner sides of the insert plate, respectively.

[0010] By adopting the above technical solution, the insert plate can be screwed into the slot, thereby connecting the outer shell with the fixture cover.

[0011] Furthermore, the slot is threadedly connected to the insert plate.

[0012] By adopting the above technical solution, the threaded connection between the slot and the insert plate greatly improves the overall tightness and will not be damaged during use.

[0013] Furthermore, the sealing mechanism includes a first anti-loosening pad slidably connected in the first groove, a second anti-loosening pad fixedly connected in the second groove, the surfaces of the first and second anti-loosening pads are provided with oblique teeth, a sealing soft pad is sandwiched between the first and second anti-loosening pads, and a sealing ring is provided at the bottom of the inner wall surface of the slot.

[0014] By adopting the above technical solution, after the insert plate is screwed into the slot, it will compress the sealing ring, thereby sealing the outer shell and the fixture cover. During the process of screwing the insert plate into the slot, the first anti-loosening pad and the second anti-loosening pad will come closer together. When the insert plate descends to a certain extent, the first anti-loosening pad and the second anti-loosening pad will compress the sealing pad in the middle. Because the first anti-loosening pad slides in the first groove, and the opposing surfaces of the first anti-loosening pad and the second anti-loosening pad have oblique teeth, as the insert plate continues to descend, the first anti-loosening pad and the second anti-loosening pad will clamp the sealing pad more tightly, further sealing the inside of the outer shell and greatly improving the overall sealing effect.

[0015] Furthermore, a baffle is fixedly connected to the inner wall of the outer shell, and the fixture plate is placed above the baffle.

[0016] By adopting the above technical solution, the baffle provides a platform for placing the fixture plate, so that the fixture plate can be placed inside the outer shell, making it convenient for the dispensing machine to pass through the fixture cover and dispense glue onto its plug.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By using a vacuum gauge and transparent glass, this utility model allows operators to monitor the vacuum level inside the vacuum fixture in real time when evacuating it, preventing damage to the connectors caused by excessively high or low vacuum levels. At the same time, operators can observe the degassing process of the vacuum fixture through the transparent glass, greatly improving its practicality.

[0019] 2. With the design of the insert plate and slot, the outer shell and the fixture cover can be threadedly connected through the slot and insert plate. The threaded connection of the slot and insert plate greatly improves the overall tightness and will not be damaged during use.

[0020] 3. Through the sealing structure, this utility model compresses the sealing ring after the insert plate is screwed into the slot, thereby sealing the outer shell and the fixture cover. During the process of screwing the insert plate into the slot, the first anti-loosening pad and the second anti-loosening pad will come closer together. When the insert plate descends to a certain extent, the first anti-loosening pad and the second anti-loosening pad will compress the sealing pad in the middle. Because the first anti-loosening pad slides in the first groove, and the opposing surfaces of the first anti-loosening pad and the second anti-loosening pad have oblique teeth, the first anti-loosening pad and the second anti-loosening pad will clamp the sealing pad more tightly during the continuous descent of the insert plate, further sealing the inside of the outer shell and greatly improving the overall sealing effect.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Reference Figure 1-5 This utility model provides an auxiliary tooling for an airtight connector, including a vacuum fixture 1. A vacuum machine and a dispensing machine are located on both sides of the vacuum fixture 1. A fixture plate 5 is located within the vacuum fixture 1. The vacuum fixture 1 is divided into a housing 2 and a fixture cover 3. A baffle 23 is fixedly connected to the inner wall of the housing 2. The fixture plate 5 is placed above the baffle 23, which provides a platform for the fixture plate 5, allowing it to be placed inside the housing 2. This facilitates the dispensing machine's needle passing through the fixture cover 3 to dispense adhesive onto the connector. The housing 2 has an upward-opening cylindrical structure. The top wall of the housing 2 is provided with a slot 21. The top wall of the housing 2 is provided with a first groove 22 on the outer side and the inner side of the slot 21. The fixture cover 3 is a cylindrical structure with the opening facing downward. The bottom wall of the fixture cover 3 is fixedly connected with a plate 31. The bottom wall of the fixture cover 3 is provided with a second groove 32 on the outer side and the inner side of the plate 31. The plate 31 can be screwed into the slot 21, thereby connecting the housing 2 and the fixture cover 3. The threaded connection of the slot 21 and the plate 31 greatly improves the overall tightness and will not be damaged during use.

[0031] Reference Figure 1-5Both the outer shell 2 and the fixture cover 3 are equipped with sealing mechanisms 4. The sealing mechanism 4 includes a first anti-loosening pad 41 slidably connected in the first groove 22, and a second anti-loosening pad 42 fixedly connected in the second groove 32. The surfaces of both the first and second anti-loosening pads 41 and 42 are provided with oblique teeth. A sealing soft pad 43 is sandwiched between the first and second anti-loosening pads 41 and 42. A sealing ring 44 is provided at the bottom of the inner wall of the slot 21. After the insert plate 31 is screwed into the slot 21, it will compress the sealing ring 44, thereby sealing the outer shell 2 and the fixture cover 3. During the process, the first anti-loosening pad 41 and the second anti-loosening pad 42 will come closer together. When the insert plate 31 descends to a certain extent, the first anti-loosening pad 41 and the second anti-loosening pad 42 will squeeze the middle sealing pad 43. Because the first anti-loosening pad 41 slides in the first groove 22, and the opposing surfaces of the first anti-loosening pad 41 and the second anti-loosening pad 42 have oblique teeth, as the insert plate 31 continues to descend, the first anti-loosening pad 41 and the second anti-loosening pad 42 will clamp the sealing pad 43 more tightly, further sealing the inside of the outer shell 2 and greatly improving the overall sealing effect.

[0032] Reference Figure 1-5 A vacuum gauge 6 is installed on the fixture cover 3. The vacuum gauge 6 is connected to the inside of the outer shell 2. A transparent glass 7 is provided on the wall of the outer shell 2. When the operator is evacuating the vacuum fixture 1, the operator can monitor the vacuum level inside the vacuum fixture 1 in real time through the vacuum gauge 6, so as to avoid damage to the connector caused by excessively high or low vacuum. At the same time, the operator can observe the defoaming of the vacuum fixture 1 through the transparent glass 7, which greatly improves the practicality.

[0033] The specific implementation method is as follows: In use, first place the jig plate 5 on the baffle 23, then screw the insert plate 31 under the jig cover 3 into the slot 21 along the thread. When the insert plate 31 descends to the bottom, it can squeeze the sealing ring 44 at the bottom of the slot 21, thereby achieving the effect of sealing the inside of the outer shell 2. During the process of screwing the insert plate 31 into the slot 21, the first anti-loosening pad 41 and the second anti-loosening pad 42 will come closer to each other, and then the first anti-loosening pad 41 and the second anti-loosening pad 42 will squeeze the middle sealing pad 43. Because the first anti-loosening pad 41 slides in the first groove 22, and the first anti-loosening pad 41 and the second anti-loosening pad 42 are opposite to each other... The surfaces of all parts are provided with helical teeth. As the insertion plate 31 continues to descend, the first anti-loosening pad 41 and the second anti-loosening pad 42 will clamp and engage the middle sealing pad 43. At the same time, as the distance between the first anti-loosening pad 41 and the second anti-loosening pad 42 gets closer and closer, the sealing pad 43 will be clamped tighter and tighter, further improving the overall sealing effect. Meanwhile, when the operator is evacuating the vacuum fixture 1, the vacuum gauge 6 can monitor the vacuum level inside the vacuum fixture 1 in real time, avoiding damage to the connector caused by excessively high or low vacuum. Furthermore, the operator can observe the de-bubbling of the vacuum fixture 1 through the transparent glass 7, which greatly improves its practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
