Description

Technical Field

[0001] This utility model relates to the field of connector base technology, and in particular to an anti-interference connector base. Background Technology

[0002] The connector base is the main structure of the connector, usually made of metal or engineering plastic. It is responsible for bearing the contacts, providing mechanical support, ensuring electrical isolation, and defining the connector's installation method and environmental protection level. Its design directly determines the connector's mechanical reliability, electrical performance, and environmental adaptability.

[0003] A search revealed that Chinese patent CN222214566U discloses a connector base that addresses the issue of loosening between the male and female connectors during factory production, logistics transportation, equipment installation, and subsequent use, especially when encountering drops, vibrations, or being pulled by a vehicle. Furthermore, as the connector ages, the connection between the male and female connectors gradually weakens, making them prone to detachment. This can easily lead to poor contact, affecting normal use, and even causing dangerous situations such as electrical sparks. Therefore, this patent aims to improve the tightness of the connection between the male and female connectors.

[0004] While the aforementioned connector base facilitates a secure connection between the male and female heads in the event of drops, vibrations, or when pulled by a vehicle, when it is installed in a fixed position within industrial equipment such as motors or compressors, the entire connector base will vibrate due to the operation of the equipment when it is turned on. Since connector bases are typically connected using bolts and nuts, which have weak resistance to vibration interference, prolonged vibration can easily cause the bolts and nuts to collide with the connector base's connecting parts, resulting in loosening and insecure fixing. It can also cause internal components to vibrate and be damaged due to prolonged vibration, thus reducing the service life of the connector base. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-interference connector base.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-interference connector base body, comprising a connector base body, wherein connectors are fixedly connected to both sides of the connector base body, and a buffer assembly is provided below the connector base body;

[0007] The buffer assembly includes a base plate disposed below the connector base body. The inner wall of the base plate has multiple sliding grooves, and the lower surface of the sliding grooves has a sealing slide. A limit frame is fixedly connected inside the sealing slide, and a piston is slidably connected inside the sealing slide. A connecting frame is fixedly connected to one side of the piston, and one end of two of the connecting frames is hinged to an arc plate.

[0008] As a further description of the above technical solution:

[0009] The connecting frame is slidably connected inside the slide groove, and an extrusion column is fixedly connected to the lower surface of the arc plate, with a pressure pad provided at one end of the extrusion column.

[0010] As a further description of the above technical solution:

[0011] The pressure pad is made of rubber, the arc plate is made of spring steel, and two fixed shells are fixedly connected to the middle of the base plate. The pressure pad is slidably connected inside the fixed shell.

[0012] As a further description of the above technical solution:

[0013] Two connecting posts are fixedly connected to both sides of the base plate, and two fixing frames are fixedly connected to both sides of the connector base body. The connecting posts are slidably connected inside the fixing frames.

[0014] As a further description of the above technical solution:

[0015] A clamping assembly is provided on one side of the connector base body. The clamping assembly includes two mounting frames, which are fixedly connected to one side of the connector base body. A limit groove is provided on one side of each mounting frame.

[0016] As a further description of the above technical solution:

[0017] The mounting frame is internally connected to a bidirectional lead screw, one end of which is fixedly connected to a shaft. One end of one of the shafts is fixedly connected to a knob. A synchronous pulley is fixedly connected to the outside of the shaft. A synchronous belt is provided on the outside of the two synchronous pulleys. A protective shell is fixedly connected to one side of the connector base body. The two shafts are rotatably connected inside the protective shell.

[0018] As a further description of the above technical solution:

[0019] The external thread of the bidirectional lead screw has two moving blocks. The moving blocks have threaded holes inside. A rotating rod is hinged to one side of the moving block. The moving blocks are slidably connected to one side of the limiting groove. One end of the two rotating rods is hinged to a fastening plate. A toothed groove is opened on one side of the fastening plate. An anti-slip pad is provided on one side of the fastening plate. The anti-slip pad is made of silicone.

[0020] This utility model has the following beneficial effects:

[0021] With the inclusion of a buffer assembly, this invention utilizes the elastic deformation of an arc-shaped plate to provide the first layer of buffering and vibration damping for the connector base body. The deformation of the arc-shaped plate pushes the pistons on both sides to open and compress the sealed slideway, generating air pressure to create pneumatic damping, thus providing the second layer of buffering and vibration damping. Furthermore, when the arc-shaped plate deforms, it pushes the pressure pad to slide and rub downwards within the fixed shell, generating frictional energy dissipation and providing the third layer of buffering and vibration damping. This design helps reduce vibration interference to the connector base body, thereby extending its service life.

[0022] With the clamping assembly, this invention utilizes two closely spaced fastening plates at the connection port of the connector base body to effectively clamp the connector head inserted into the connection port. This reduces the risk of accidental contact with the connector head during manual maintenance and use, which could lead to the connector head detaching from the connection port and causing loosening. Furthermore, the anti-slip pads and toothed grooves further enhance the tightness of the fastening plates in clamping the connector head, reducing the occurrence of minor displacement at the connection port. Simultaneously, the connection of the synchronous belt and synchronous pulley facilitates the simultaneous rotation of the two shafts when turning the knob, thereby improving the convenience of clamping the connector head.

[0033] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] As attached Figure 1-8 As shown, one embodiment of the present invention is provided: an anti-interference connector base body, including a connector base body 1, with connectors 2 fixedly connected to both sides of the connector base body 1, and a buffer assembly provided below the connector base body 1.

[0035] The buffer assembly includes a base plate 3, which is located below the connector base body 1. The inner wall of the base plate 3 has multiple grooves 5, and the lower surface of the grooves 5 has a sealing slide 4. A limit frame 6 is fixedly connected inside the sealing slide 4, and a piston 7 is slidably connected inside the sealing slide 4. A connecting frame 8 is fixedly connected to one side of the piston 7, and an arc plate 9 is hinged to one end of two connecting frames 8. The sealing slide 4 facilitates the connection of the piston 7, thereby forming a pneumatic damping buffer. The arc plate 9 will deform when the connector base body 1 is pressed down, playing the role of elastic deformation buffer, thereby playing the role of buffering and vibration resistance.

[0036] As attached Figure 3As shown, the connecting frame 8 is slidably connected inside the slide groove 5. The lower surface of the arc plate 9 is fixedly connected to the extrusion column 10. One end of the extrusion column 10 is provided with a pressure pad 11. The pressure pad 11 is made of rubber. The arc plate 9 is made of spring steel. Two fixed shells 12 are fixedly connected to the middle of the base plate 3. The pressure pad 11 is slidably connected inside the fixed shell 12. Two connecting columns 13 are fixedly connected to both sides of the base plate 3. When the pressure pad 11 slides inside the fixed shell 12, it can play a role in buffering and damping under the action of friction.

[0037] As attached Figure 6 As shown, two fixed frames 14 are fixedly connected to both sides of the connector base body 1, and the connecting post 13 is slidably connected inside the fixed frame 14 to facilitate the connection between the base plate 3 and the connector base body 1.

[0038] As attached Figure 7 As shown, a clamping assembly is provided on one side of the connector base body 1. The clamping assembly includes two mounting frames 15, which are fixedly connected to one side of the connector base body 1. A limiting groove 16 is provided on one side of the mounting frame 15. A bidirectional lead screw 17 is rotatably connected inside the mounting frame 15. A shaft 18 is fixedly connected to one end of the bidirectional lead screw 17. A knob 19 is fixedly connected to one end of one of the shafts 18. The limiting groove 16 limits the movement of the moving block 23. Under the action of the threads in opposite directions on both sides of the bidirectional lead screw 17, it is easy to drive the two moving blocks 23 to move closer or further apart.

[0039] As attached Figure 6 As shown, a synchronous pulley 20 is fixedly connected to the outside of the shaft 18, and a synchronous belt 21 is provided on the outside of the two synchronous pulleys 20. A protective shell 22 is fixedly connected to one side of the connector base body 1. The two shafts 18 are rotatably connected inside the protective shell 22. The protective shell 22 protects the synchronous pulleys 20 and the synchronous belt 21.

[0040] As attached Figure 8 As shown, the external thread of the bidirectional lead screw 17 has two moving blocks 23. The moving blocks 23 have threaded holes inside. A rotating rod 24 is hinged to one side of the moving blocks 23. The moving blocks 23 are slidably connected to one side of the limiting groove 16. One end of the two rotating rods 24 is hinged to a fastening plate 25. The threaded holes match the threads of the bidirectional lead screw 17. When the two fastening plates 25 are close to both sides of the connector, they can clamp the connector.

[0041] As attached Figure 6 As shown, a toothed groove is provided on one side of the fastening plate 25, and an anti-slip pad 26 is provided on one side of the fastening plate 25. The anti-slip pad 26 is made of silicone. The toothed groove and the anti-slip pad 26 help to enhance the anti-slip effect of the fastening plate 25.

[0042] Working principle: After the connector base body 1 is installed in a suitable position using the connector 2, when the connector base body 1 is subjected to vibration due to the operation of external industrial equipment, the vibration will cause the connector base body 1 to shake up and down. When it moves down, it will squeeze the two arc plates 9, causing the two arc plates 9 to deform under pressure, generating elastic deformation buffer. When the arc plates 9 deform, the connecting frame 8 will be pushed by both sides to slide inside the slide groove 5. The connecting frame 8 will push the piston 7 to slide inside the sealing slide 4, compressing the air inside the sealing slide 4, forming pressure, generating air pressure damping buffer, which helps to play the role of vibration reduction and buffering. When the arc plates 9 deform and the center moves down, it will drive the extrusion column 10 to push the pressure pad 11 to slide inside the fixed shell 12. Under the action of friction, friction energy dissipation buffering is generated, further enhancing the anti-vibration buffering effect.

[0043] When the connector is inserted into the connection port on one side of the connector base body 1, the knob 19 is turned, causing the knob 19 to drive one of the shafts 18 to rotate. When the two shafts 18 are connected by the synchronous pulley 20 and the synchronous belt 21, the rotation of one shaft 18 will drive the other shaft 18 to rotate, thereby causing the two bidirectional lead screws 17 to rotate. Under the action of the opposite direction threads of the bidirectional lead screws 17, the two moving blocks 23 on both sides will move away from each other when sliding inside the limiting groove 16, thereby pushing the rotating rod 24 to rotate, so that the rotating rod 24 pushes the fastening plate 25 to come closer to the connector, and then clamps it under the connection of the anti-slip pad 26.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
