Description

Technical Field

[0001] This utility model belongs to the field of terminal technology, specifically a short-circuit protection insulation structure for the pins of a miniaturized terminal connector. Background Technology

[0002] Miniaturized terminal connector pins are precision conductive structures specifically designed for miniaturized devices. These pins are typically tin-plated, support extreme temperatures from -40°C to 125°C, and have a 3A rated current carrying capacity, making them compatible with surface mount technology (SMT). In terms of applications, miniaturized terminal connectors are widely used in industrial robots, medical devices, automotive electronics, and other scenarios with stringent precision requirements. Typical applications include industrial PLC controllers, medical device sensors, and automotive circuit modules. By providing high-speed data transmission and reliable power connections, they have become a key supporting technology for device miniaturization and integration.

[0003] Existing miniaturized terminal connectors have poor isolation and insulation capabilities for their pins, which cannot effectively protect the pin connections and poses safety hazards. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a short-circuit protection insulation structure for the pins of a miniaturized terminal connector, which effectively solves the problem that the existing miniaturized terminal connector pins have poor isolation insulation capability and cannot effectively protect the connection of the pins, thus posing a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a short-circuit insulation structure for a miniaturized terminal connector pin, comprising a terminal body, a pin-shaped pin fixedly mounted on the inner wall of one end of the terminal body, a movable ring provided inside the terminal body at one end, an insulating sleeve rotatably connected to one side of the movable ring, a mounting groove opened on the inner wall of the other end of the terminal body, a fixing ring fixedly mounted in the center of the mounting groove, openings at the upper and lower parts of the circumferential surface of the fixing ring, two insertion holes opened on the surface of the fixing ring, two connecting ears symmetrically fixedly mounted on the surface of the insulating sleeve, and a pin fixedly mounted on one side of each connecting ear. The two plug rods are adapted to the two sockets and are inserted into the two sockets. The upper and lower parts of the moving ring away from the insulating sleeve are fixedly installed with fixing blocks. The ends of the two fixing blocks that are far from each other are fixedly installed with limiting sleeves. The inside of the two limiting sleeves are movably inserted with limiting slide rods. The upper and lower parts of the inside of the insulating sleeve are provided with strip grooves. The two ends of the two limiting slide rods are respectively fixedly installed on the inner wall of one end of the two strip grooves and one end of the two limiting sleeves. The surface of the two limiting slide rods is covered with a first spring. The two ends of the two first springs are respectively fixedly connected to the limiting sleeves and the inner walls of the two strip grooves.

[0006] Preferably, a pushing ring is fitted on one end of each limiting slide rod surface, and a second spring is fixedly installed on one side of each pushing ring. The two second springs are respectively fitted on the surfaces of the two limiting slide rods, and the ends of the two second springs away from the pushing rings are respectively fixedly connected to the inner walls of the other ends of the two strip grooves.

[0007] Preferably, an annular groove is provided on one side of the movable ring, a limiting slip ring is slidably installed inside the annular groove, four connectors are fixedly installed at equal intervals on one side of the limiting slip ring, a limiting ring is fixedly installed between one end of the four connectors, and the limiting ring is installed inside the mounting groove, and an insulating isolation sleeve is fixedly installed on one side of the limiting ring.

[0008] Preferably, a rubber suction cup is fixedly installed at one end of the insulating sleeve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When not in use, the insulating sleeve effectively protects the pin-shaped pins, preventing them from being bent by external forces. At the same time, the insulating sleeve is in a locked state, which can prevent the insulating sleeve from moving and shrinking, thus ensuring the stability of the protection. When it is necessary to connect with the female terminal, the operator first pulls the insulating sleeve outward. When the insulating sleeve is pulled, the moving ring and two fixed blocks drive the two limiting sliding sleeves to slide along the surface of the two limiting sliding rods. At the same time, the two pushing rings squeeze the two second springs, so that the insulating sleeve drives the two plug rods to exit the two plug holes through the two connecting ears and releases the limit. Then the operator rotates the insulating sleeve by °. When the insulating sleeve rotates, the four connecting heads drive the limiting sliding rings to slide inside the annular sliding groove, ensuring the stability during rotation. The two connecting ears are aligned with the two openings. Then the operator releases the insulating sleeve, so that the insulating sleeve moves a certain distance into the terminal body under the elastic force of the two second springs, so that the two connecting ears exit the mounting groove through the two openings and release the limit.

[0010] The operator then inserts the pin-shaped leads on the terminal body into the female terminal. During the insertion of the pin-shaped leads into the female terminal, the insulating sleeve is pushed inward and retracts into the terminal body, while the rubber suction cup is simultaneously adsorbed onto the surface of the female terminal, improving the protective effect. When the terminal body retracts and moves, it drives the two limiting sleeves to move inward along the surface of the two limiting slide rods through the moving ring and two fixing blocks, while simultaneously squeezing the two first springs. The elastic force of the two first springs can push the insulating sleeve to drive the rubber suction cup to firmly adhere to the female terminal. This gives the pins of this miniaturized terminal connector good isolation and insulation capabilities, effectively protecting the connection of the pins. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 7The present invention includes a terminal body 1. A pin-shaped lead 2 is fixedly installed on the inner wall of one end of the terminal body 1. A movable ring 4 is provided inside the terminal body 1. An insulating isolation sleeve 3 is rotatably connected to one side of the movable ring 4. An installation groove 13 is opened on the inner wall of the other end of the terminal body 1. A fixing ring 14 is fixedly installed in the middle of the installation groove 13. An opening 22 is opened on the upper and lower parts of the circumferential surface of the fixing ring 14. Two insertion holes 18 are opened on the surface of the fixing ring 14. Two connecting ears 16 are symmetrically fixedly installed on the surface of the insulating isolation sleeve 3. A plug rod 17 adapted to the two insertion holes 18 is fixedly installed on one side of each of the two connecting ears 16. The two plug rods 17 are inserted into the inside of the two insertion holes 18.

[0023] When not in use, the insulating sleeve 3 effectively protects the pin-shaped pin 2, preventing it from being bent by external forces. At the same time, the insulating sleeve 3 is in a locked state, which can prevent the insulating sleeve 3 from moving and shrinking, thereby ensuring the stability of the protection.

[0024] Fixed blocks 7 are fixedly installed on the upper and lower parts of the movable ring 4 away from the insulating sleeve 3. Limiting sleeves 8 are fixedly installed on the ends of the two fixed blocks 7 that are far apart from each other. Limiting rods 9 are movably inserted into the interior of the two limiting sleeves 8. Strip grooves 15 are opened in the upper and lower parts of the interior of the insulating sleeve 3. The two ends of the two limiting rods 9 are respectively fixedly installed on the inner wall of one end of the two strip grooves 15 and one end of the two limiting sleeves 8. The surface of the two limiting rods 9 is fitted with a first spring 10. The two ends of the two first springs 10 are respectively fixedly connected to the limiting sleeves 8 and the inner walls of the two strip grooves 15.

[0025] Each end of the limiting slide bar 9 is fitted with a push ring 11. A second spring 12 is fixedly installed on one side of each push ring 11. Each of the two second springs 12 is fitted onto the surface of the two limiting slide bars 9. The ends of the two second springs 12 away from the push ring 11 are fixedly connected to the inner walls of the other ends of the two strip grooves 15.

[0026] When it is necessary to connect to the female terminal, the operator first pulls the insulating sleeve 3 outward. When the insulating sleeve 3 is pulled, the moving ring 4 and the two fixed blocks 7 drive the two limiting sliding sleeves 8 to slide along the surface of the two limiting sliding rods 9, and at the same time push the two pushing rings 11 to squeeze the two second springs 12, so that the insulating sleeve 3 drives the two plug rods 17 out of the two plug holes 18 through the two connecting ears 16 to release the limit. Then the operator rotates the insulating sleeve 3 90° so that the two connecting ears 16 are aligned with the two openings 22. Then the operator releases the insulating sleeve 3, so that the insulating sleeve 3 moves a certain distance into the terminal body 1 under the elastic force of the two second springs 12, so that the two connecting ears 16 are out of the mounting groove 13 through the two openings 22 to release the limit.

[0027] Then, the operator inserts the pin-shaped pin 2 on the terminal body 1 into the female terminal. During the insertion of the pin-shaped pin 2 into the female terminal, it pushes the insulating sleeve 3 to retract into the interior of the terminal body 1, and at the same time, it adsorbs the rubber suction cup 21 onto the surface of the female terminal, improving the protection effect. When the terminal body 1 retracts and moves, it drives the two limiting sleeves 8 to move inward along the surface of the two limiting slide rods 9 through the moving ring 4 and the two fixing blocks 7, and at the same time, it squeezes the two first springs 10. The elastic force of the two first springs 10 can push the insulating sleeve 3 to drive the rubber suction cup 21 to adhere tightly to the female terminal. This gives the pins of this miniaturized terminal connector good isolation and insulation capabilities, and can effectively insulate and protect the connection of the pins.

[0028] An annular groove 5 is provided on one side of the movable ring 4. A limiting slip ring 6 is slidably installed inside the annular groove 5. Four connectors 19 are fixedly installed at equal intervals on one side of the limiting slip ring 6. A limiting ring 20 is fixedly installed between one end of the four connectors 19, and the limiting ring 20 is installed inside the mounting groove 13. An insulating isolation sleeve 3 is fixedly installed on one side of the limiting ring 20. A rubber suction cup 21 is fixedly installed on one end of the insulating isolation sleeve 3.

[0029] When the insulating sleeve 3 rotates, it drives the limiting slip ring 6 to slide inside the annular groove 5 through the four connectors 19, ensuring the stability during rotation.
