Technical Field
[0001] This utility model relates to the technical field of electrical connectors, specifically to the cover fastening structure of an electrical connector. Background Technology
[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between them.
[0003] Electrical connectors are designed to accommodate multiple terminals. To protect and maintain these terminals, an openable cover is required. Existing electrical connectors, such as the cover holding structure described in patent publication number CN201937100U, have a cover with multiple holding elements connected to one side of the connector's base. The cover can open and close 180 degrees between the base and the base, with the cover and base being integrally molded. This integrates the mold between the cover and the base, simplifying the manufacturing process.
[0004] However, due to its use of fixed fasteners, it is inconvenient to open and close, and is prone to falling off over time, resulting in poor reliability. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cover holding structure for an electrical connector that features a flip-up elastic reset slot structure for easy opening and closing operations. Furthermore, it eliminates the need for frequently moving fixed parts, resulting in a longer lifespan and improved practicality due to its movable connection method.
[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a cover fastening structure for an electrical connector, including an electrical connector, a base, a top cover, a fastening slot frame, a bushing frame, a movable shaft, a sleeve frame, a sliding pin, a pull tab, a connecting spring, and a snap fastener. The base is sleeved on the outside of the electrical connector. The upper rear side of the base is rotatably connected to the rear side of the top cover via a movable connecting part. The upper left and right sides of the front end of the base are respectively connected to the rear side of a set of fastening slot frames. The left and right sides of the front end of the top cover are respectively connected to the rear side of a set of bushing frames. The inner wall of each set of bushing frames is rotatably connected to the outer wall of a set of movable shafts. The two ends of the movable shaft are respectively connected to the inner side of the upper side of the sleeve frame. The lower inner wall of the sleeve frame is slidably connected to the outer wall of the sliding pin. The top side of the sliding pin is connected to the middle of the bottom side of the snap fastener. The bottom side of the sliding pin is connected to the rear side of the top of the pull tab. A connecting spring is connected to the outer side of the sliding pin at the top of the pull tab and the outer side of the sliding pin at the bottom of the sleeve frame.
[0007] Preferably, the movable connection part includes a fixed connection part, a constraint shaft, a movable sleeve, and a cover connector. The upper side of the rear end of the seat body is connected to the front side of the fixed connection part. A set of constraint shafts is connected to the middle of the left and right sides of the fixed connection part. The outer side of each set of constraint shafts is movably connected to the inner side of a set of movable sleeves. The two sets of movable sleeves are connected to the corresponding positions on the rear side of the upper cover via a set of cover connectors.
[0008] Preferably, it also includes a flared groove, wherein a flared groove is provided on the outer side of the groove at the bottom end of the buckle frame.
[0009] Preferably, it also includes an information board, with the top side of the upper cover connected to the bottom side of the information board.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a cover fastening structure for an electrical connector, which has the following advantages: The cover is fitted onto the outside of the electrical connector. When protection is required, the cover can be closed under the constraint of the movable connecting part. Then, the movable shaft is rotated under the constraint of the bushing frame. Pulling the pull tab stretches the connecting spring, causing the sliding pin to be in a lower position. The sleeve frame is then closed downwards, and the inner groove of the sleeve frame fits onto the outer side of the buckle frame. After releasing the pull tab, the sliding pin slides upwards on the bottom side of the sleeve frame under the elastic contraction of the connecting spring, and the buckle pin enters into the buckle frame. Thus, through the connection of the buckle frame, buckle, sliding pin, sleeve frame, movable shaft, and bushing frame, the cover is closed and fixed, forming protection. The flip-up elastic reset buckle structure facilitates opening and closing operations. Moreover, it has no frequently moving fixed parts, and the movable connection method results in a longer service life and improved practicality. Attached Figure Description

Example
[0015] Please see Figure 1-4 The cover fastening structure of the electrical connector includes the electrical connector 1, and also includes a base 2, an upper cover 3, a fastening slot frame 4, a bushing frame 5, a movable shaft 6, a sleeve frame 7, a sliding pin 8, a pull tab 9, a connecting spring 10, and a snap fastener 11. The base 2 is sleeved on the outside of the electrical connector 1. The upper rear part of the base 2 is rotatably connected to the rear side of the upper cover 3 via a movable connecting part. The upper left and right front sides of the base 2 are respectively connected to the rear side of a set of fastening slot frames 4. The left and right front sides of the upper cover 3 are respectively connected to the rear side of a set of bushing frames 5. The inner wall of each set of bushing frames 5 is rotatably connected to the outer wall of a set of movable shafts 6. The two ends of the movable shafts 6 are respectively connected to the upper interior of the sleeve frame 7. The lower inner wall of the sleeve frame 7 is slidably connected to the outer wall of the sliding pin 8. The top side of the sliding pin 8 is connected to the middle of the bottom side of the snap fastener 11. The bottom side of the sliding pin 8 is connected to the rear side of the top of the pull tab 9. Connecting the pull tab 9, the outer side of the sliding pin 8 at the top of the pull tab 9 is connected to the outer side of the sliding pin 8 at the bottom of the sleeve 7, and a connecting spring 10 is connected to the outer side of the electrical connector 1 by the seat 2. When protection is required, the upper cover 3 can be closed under the constraint of the movable connecting part. Then, the movable shaft 6 is rotated under the constraint of the bushing frame 5. Pulling the pull tab 9 stretches the connecting spring 10, so that the sliding pin 8 is connected to the buckle 11 in a lower position, and the sleeve 7 is closed downward. The inner groove of the sleeve 7 is fitted onto the outer side of the buckle frame 4. Then, the pull tab 9 is released, and under the elastic contraction of the connecting spring 10, the sliding pin 8 slides upward on the bottom side of the sleeve 7 and is pinned into the buckle frame 4 by the buckle 11. Thus, through the connection of the buckle frame 4, the buckle 11, the sliding pin 8, the sleeve 7, the movable shaft 6 and the bushing frame 5, the upper cover 3 is closed and fixed to form protection.
[0016] The movable connection part includes a fixed connection part 12, a constraint shaft 13, a movable sleeve 14, and a cover connector 15. The upper rear end of the seat body 2 is connected to the front side of the fixed connection part 12. A set of constraint shafts 13 are respectively connected to the middle of the left and right sides of the fixed connection part 12. The outer side of each set of constraint shafts 13 is movably sleeved with the inner side of a set of movable sleeves 14. The two sets of movable sleeves 14 are respectively connected to the corresponding positions on the rear side of the upper cover 3 through a set of cover connectors 15. The constraint shafts 13 are fixed on the rear side of the seat body 2 by the fixed connection part 12. They can rotate and move under the constraint of the corresponding constraint shafts 13 through the two sets of movable sleeves 14, so that the upper cover 3 can be flipped open and closed.
[0017] It also includes a flared groove 16, which is provided on the outer side of the groove at the bottom of the buckle frame 4; the flared groove 16 can be used to widen the lower groove of the buckle frame 4, so that the buckle 11 can be inserted into the buckle frame 4.
[0018] It also includes an information board 17, with the top side of the upper cover 3 connected to the bottom side of the information board 17; the information board 17 can display information about the device, making it easier to read and assist in operation, thus improving convenience.
[0019] The base 2 and the top cover 3 are made of rigid PVC material; they have lower cost, higher quality, and better resistance to oxidation and corrosion, thus improving reliability.
[0020] In summary, during use, the cover holding structure of the electrical connector is fitted onto the outside of the electrical connector 1 by the base 2. When protection is required, the constraint shaft 13 is fixed to the rear side of the base 2 by the fixed connecting part 12. Under the constraint of the corresponding constraint shaft 13, the two sets of movable sleeves 14 rotate and move, allowing the upper cover 3 to be flipped open and closed. When the upper cover 3 is closed, the movable shaft 6 is rotated under the constraint of the bushing frame 5. Pulling the pull tab 9 stretches the connecting spring 10, causing the sliding pin 8 to connect the buckle 11 to be in a lower position, thus closing the sleeve frame 7 downwards. When closed, the inner groove of the sleeve 7 is fitted onto the outer side of the buckle frame 4. After the pull tab 9 is released, the sliding pin 8 slides upward on the bottom side of the sleeve 7 under the elastic contraction of the connecting spring 10. The lower groove of the buckle frame 4 can be widened through the flared groove 16, which facilitates the insertion of the buckle 11 into the buckle frame 4. Thus, through the connection of the buckle frame 4, the buckle 11, the sliding pin 8, the sleeve 7, the movable shaft 6, and the bushing frame 5, the upper cover 3 is closed and fixed to form protection. In addition, the information plate 17 can display the information of this device, which is convenient for reading and assisting in operation.
