Description

Technical Field

[0001] This utility model relates to the field of optical fiber fusion splicer technology, specifically a protective mechanism for the battery connector of an optical fiber fusion splicer. Background Technology

[0002] In the construction and maintenance of optical fiber communication networks, fiber optic fusion splicers are indispensable key equipment. They are primarily used for fiber optic splicing operations, ensuring the quality and stability of fiber optic connections. The battery components of fiber optic fusion splicers are mostly detachable, with male connectors inside the battery chamber adapting to the female connectors of the battery components, thus facilitating battery replacement. However, the PCB boards of the battery connectors in existing fiber optic fusion splicers are often directly exposed to the external environment. For example, in CN215678850U, a reverse-charging fiber optic fusion splicer, the PCB board of the connector lacks an effective protective structure. In dusty outdoor environments, dust easily adheres to the PCB board of the connector, potentially causing poor contact between the battery and the fusion splicer, leading to unstable power supply, splicing interruptions, and oxidation and corrosion of the solder joints on the PCB board. This significantly shortens the lifespan of the connector, increases equipment maintenance costs, and raises the risk of operational failures, indicating certain shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a protective mechanism for the battery connector of a fiber optic fusion splicer to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for a battery connector of a fiber optic fusion splicer, comprising a male connector assembly, wherein the male connector assembly comprises a PCB board with conductive contacts and a PCB board mounting post fixedly connected to the housing of the fusion splicer, the PCB board being mounted on the top of the PCB board mounting post by bolts, a lower shell assembly being mounted at the bottom of the male connector assembly, and an upper shell assembly being magnetically mounted at the top of the lower shell assembly.

[0005] The upper shell assembly includes an upper shell and a dustproof mesh. The upper shell has multiple through slots at equal intervals.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 6 The present invention provides a technical solution: a protective mechanism for the battery connector of a fiber optic fusion splicer, comprising an upper shell assembly 2, a lower shell assembly 1, and a male connector assembly 3.

[0023] The lower housing assembly 1 consists of a lower housing 11, a spring-shaped rubber sleeve 12, and a rear sealing plate 14. The spring-shaped rubber sleeve 12 is made of elastic rubber and is fixedly installed on the top of one side of the lower housing 11. A contact groove 12a adapted to the contact of the male connector assembly 3 is opened on one side of the lower housing assembly 1. The rear sealing plate 14 is connected to the side of the lower housing assembly 1 away from the male connector assembly 3 by magnetic attraction. A groove sealing plate 15 is fixedly connected to the bottom of one side of the rear sealing plate 14, which is adapted to the groove 12b opened at the bottom of the lower housing 11.

[0024] The male connector assembly 3 includes a PCB board 31 with conductive contacts and a PCB board mounting post 32 fixedly connected to the housing of the welding machine. The PCB board 31 is mounted on top of the PCB board mounting post 32 by bolts.

[0025] The upper shell assembly 2 consists of an upper shell 21 and a dustproof mesh 22. Multiple through slots 21a are equidistantly spaced on the upper shell 21. The dustproof mesh 22 is magnetically attached to the area where the through slots 21a are located on the upper shell 21, effectively blocking dust particles from adhering to the PCB board 31 while ensuring heat dissipation of the PCB board 31. The bottom surfaces of the parallel side panels of the upper shell 21 have first slots 21b that mate with the first clip 13, and second slots 12c on one side of the side panels of the lower shell 11 where the first clip 13 is installed. Magnetic pieces are provided in both the first slot 21b and the second slot 12c, magnetically engaging with the first clip 13 and the second clip 16 to ensure a tight fit between the upper shell assembly 2, the lower shell assembly 1, and the rear cover plate 14, forming a unified protective structure while facilitating disassembly and maintenance.

[0026] Furthermore, a bolt post 17 is horizontally fixedly installed on the side plate of the lower housing 11 where the spring-shaped rubber sleeve 12 is installed. It cooperates with the threaded hole opened on one side of the PCB board mounting post 32. The lower housing 11 and the male connector assembly 3 can be stably installed by means of bolt connection.

[0027] Furthermore, a flexible sealing strip adapted to the size of the cable outlet groove is installed at the bottom of one side panel of the upper shell assembly 2. After the PCB board 31 exits, the flexible sealing strip can effectively reduce the occurrence of external dust entering the upper shell assembly 2 and the lower shell assembly 1 and adhering to the PCB board 31.

[0028] In actual use, the lower housing 11 is first installed at the bottom of the male connector assembly 3. A bolt is used to pass through the bolt post 17, with one end of the bolt fixed in the threaded hole of the PCB board mounting post 32. At this time, the lower housing 11 is firmly fixed. After installation, the contact of the male connector assembly 3 passes through the contact groove 12a1mm-2mm of the spring-shaped rubber sleeve 12 to ensure good contact with the female connector of the battery assembly. Then, the rear cover plate 14 is connected to the back of the lower housing assembly 1 by magnetic attraction, completing the assembly of the lower housing assembly 1. Finally, the upper housing assembly 2 is installed on top of the lower housing assembly 1 by magnetic attraction. At this time, the upper housing assembly 2, the lower housing assembly 1, and the rear cover plate 14 fit tightly together, completely surrounding the male connector assembly 3, forming an all-round protective structure. This effectively reduces the probability of dust, water, and other impurities adhering to the contact of the male connector assembly 3, reduces the occurrence of corrosion of the PCB board 31, and helps to ensure the stability and reliability of the battery connection of the fiber optic fusion splicer.

[0029] When installing the battery assembly of the welding machine, the female end of the battery assembly is installed in the battery cavity of the welding machine. The female end of the battery assembly will squeeze the spring-shaped rubber sleeve 12, so that the contact of the male end assembly 3 can be smoothly inserted into the female end of the battery assembly, and the battery assembly supplies power to the welding machine.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
