Description

Technical Field

[0001] This invention relates to a connector, and more specifically, to a rugged connector. Background Technology

[0002] A connector is an electronic component with multiple connection ports, widely used in electrical wiring, electronic equipment connection and automation control. Its core function is to realize the branching, merging or signal transmission of current, while providing a reliable electrical connection.

[0003] In the connection process, existing connectors use threaded sleeves to reinforce the threads between connectors or between connectors and wires. To facilitate rotation, anti-slip textures are usually provided on the outer circumferential wall of the threaded sleeve to achieve the purpose of anti-slip.

[0004] During operation, the threaded sleeve may be affected by the connector housing's installation position or the compactness of the cable installation environment. If the threaded sleeve is tightened too much, it becomes difficult to remove it by applying lateral force. If the threaded sleeve is not properly tightened, it will cause loosening at the connection. Therefore, it is necessary to ensure that the threaded sleeve is screwed into the appropriate range during the initial installation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a reinforced connector that can improve the stability during locking.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reinforced connector, comprising a connector body, the connector body being arranged in a T-shape, and each of the three ends of the connector body being provided with a connector head, characterized in that: a sliding groove is recessed between each connector head and the connector body, and a threaded sleeve is slidably connected to each sliding groove; The connector body is provided with two sets of connecting cylinders, which are symmetrically arranged along the center of the connector body. A first limiting plate is detachably installed on one connecting cylinder, and a second limiting plate is detachably installed on the other connecting cylinder. The first limiting plate and the second limiting plate are each provided with three limiting parts. When the first limiting plate and the second limiting plate are engaged with each other, the limiting parts are respectively engaged between the threaded sleeve and the connector body. Both the first limiting plate and the second limiting plate are provided with limiting rods for insertion into the connecting cylinder, and each connecting cylinder is provided with a locking structure and an unlocking structure.

[0007] The present invention is further configured such that: the connector includes a plug and a doped plug, the plug is provided in two sets, one of the plugs is located in the middle of the connector body, and the doped plug and the other plug are symmetrically arranged at both ends along the middle of the connector body.

[0008] The present invention is further configured such that: one end of the limiting rod is rotatably connected to the corresponding first limiting plate or second limiting plate by a torsion spring, and the locking structure is a sector block disposed in the connecting cylinder; The connecting cylinder includes a limiting groove and an operating groove in sequence along the insertion direction of the limiting rod, and the diameter of the operating groove is larger than that of the limiting groove. The limiting rod includes a limiting head, a guide part, and an adjusting part in sequence along its length. The diameter of the guide part is the same as the diameter of the limiting groove, and the diameter of the adjusting part is smaller than the diameter of the guide part. A limiting area is provided between the limiting head and the guide part.

[0009] The present invention is further configured such that: the unlocking structure includes an unlocking block and a reset spring, the unlocking block is slidably connected in the operating groove, one end of the reset spring is connected to the unlocking block and the other end is connected to the groove wall of the operating groove, and the unlocking block is provided with an unlocking inclined surface on the side facing the fan-shaped block; A guide groove is provided through the connecting cylinder, and a guide arm is provided on the unlocking block. The guide arm is slidably connected in the guide groove and extends outward from the connecting cylinder.

[0010] The present invention is further configured such that: the side of the fan-shaped block facing the unlocking block is provided with a plug groove, and during the movement of the unlocking block, the unlocking inclined surface is inserted into the plug groove.

[0011] The present invention is further configured such that: the upper end of the unlocking block is provided with a mounting base, and the mounting base is provided with a pushing groove and a pushing rod on the side facing the fan-shaped block. The pushing rod is slidably connected to the pushing groove by a spring. When the unlocking block moves towards the fan-shaped block, the limiting head flips upward and abuts against the pushing rod.

[0012] The present invention is further configured such that: both the first limiting plate and the second limiting plate are provided with limiting rods and positioning rods, the limiting rods and positioning rods are respectively inserted into the two connecting cylinders, and the length of the positioning rod is smaller than the length of the limiting rod.

[0013] The present invention is further configured such that: the first limiting plate and the second limiting plate are provided with a mutually cooperating locking structure on the opposite side of each other.

[0014] The present invention is further configured such that both the first limiting plate and the second limiting plate are convex structures.

[0015] The present invention is further configured such that nameplate slots are provided on the connector body, the first limiting plate, and the second limiting plate.

[0016] In summary, the present invention has the following beneficial effects: by designing sliding grooves at three ends of the connector body, the movement stroke of the threaded sleeve can be effectively limited. When the threaded sleeve rotates in conjunction with the external threaded structure, one end of the threaded sleeve moves along the sliding groove. When the threaded sleeve rotates to its final position, the groove wall of the sliding groove abuts against it, thereby preventing the threaded sleeve from being over-tightened.

[0017] When the first and second limiting plates are installed on the connecting cylinder, the limiting part needs to be engaged between the threaded sleeve and the connector body. If the threaded sleeve cannot be rotated properly, the limiting part cannot be engaged successfully. Therefore, the rotation position of the threaded sleeve needs to be adjusted a second time to avoid the situation where the threaded sleeve cannot be rotated properly. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 5As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a reinforced connector, including a connector body 1, the connector body 1 is arranged in a T-shape, and each of the three ends of the connector body 1 is provided with a connector head, and a sliding groove 2 is recessed between each connector head and the connector body 1, and a threaded sleeve 3 is slidably connected to each sliding groove 2. The connector body 1 is provided with two sets of connecting cylinders 4. The two connecting cylinders 4 are symmetrically arranged along the center of the connector body 1. A first limiting plate 5 is detachably installed on one connecting cylinder 4, and a second limiting plate 6 is detachably installed on the other connecting cylinder 4. Three limiting parts 51 are provided on the first limiting plate 5 and the second limiting plate 6 respectively. When the first limiting plate 5 and the second limiting plate 6 are engaged with each other, the limiting parts 51 are respectively engaged between the threaded sleeve 3 and the connector body 1. Both the first limiting plate 5 and the second limiting plate 6 are provided with limiting rods 7 for insertion into the connecting cylinder 4, and each connecting cylinder 4 is provided with a locking structure 8 and an unlocking structure 9.

[0022] The design of this invention utilizes sliding grooves 2 at three ends of the connector body 1 to effectively limit the travel of the threaded sleeve 3. When the threaded sleeve 3 rotates in conjunction with the external threaded structure, one end of the threaded sleeve 3 moves along the sliding groove 2. When the threaded sleeve 3 is rotated to its final position, the groove wall of the sliding groove 2 abuts against it, thereby preventing the threaded sleeve 3 from being over-tightened.

[0023] When the first limiting plate 5 and the second limiting plate 6 are installed on the connecting cylinder 4, the limiting part 51 needs to be inserted between the threaded sleeve 3 and the connector body 1. When the threaded sleeve 3 cannot be rotated properly, the limiting part 51 cannot be successfully inserted. Therefore, it is necessary to adjust the rotation position of the threaded sleeve 3 a second time to avoid the situation where the threaded sleeve 3 cannot be rotated properly.

[0024] Furthermore, the locking structure 8 and unlocking structure 9 enable quick locking and unlocking operations, making the device easy to use.

[0025] The present invention is further configured such that: the connector includes a plug 11 and a plug 12; the plug 11 is provided in two sets, one plug 11 is located in the middle of the connector body 1, and the plug 12 and the other plug 11 are symmetrically arranged at both ends along the middle of the connector body 1. The internal structure of the connector body 1 adopts an existing structural design, and the specific style is not limited.

[0026] The present invention is further configured such that: one end of the limiting rod 7 is rotatably connected to the corresponding first limiting plate 5 or second limiting plate 6 by a torsion spring, and the locking structure 8 is a sector block 81 disposed in the connecting cylinder 4; The connecting cylinder 4 includes a limiting groove 41 and an operating groove 42 in sequence along the insertion direction of the limiting rod 7. The groove diameter of the operating groove 42 is larger than that of the limiting groove 41. The limiting rod 7 includes a limiting head 71, a guide part 72 and an adjusting part 73 in sequence along its length. The diameter of the guide part 72 is the same as the diameter of the limiting groove 41, and the diameter of the adjusting part 73 is smaller than the diameter of the guide part 72. A limiting area is provided between the limiting head 71 and the guide part 72.

[0027] The design of this structure ensures that when the limiting rod 7 is inserted into the connecting cylinder 4, the guide part 72 first slides in the limiting groove 41 to ensure the stability of the insertion of the limiting rod 7.

[0028] When the limiting head 71 abuts against the sector block 81, the adjusting part 73 is located in the limiting groove 41. When the limiting head 71 moves along the sector surface of the sector block 81, the limiting rod 7 rotates. When the limiting rod 7 continues to extend until the sector block 81 is inserted into the limiting area, the end face of the sector block 81 is flat, and the contact surface between the limiting head 71 and the sector block 81 is also flat, thus completing the fixing operation.

[0029] In the aforementioned fixed state, the first limiting plate 5 and the second limiting plate 6 cannot be separated by simple pulling, thus ensuring the stability of the fixation.

[0030] The present invention is further configured such that: the unlocking structure 9 includes an unlocking block 91 and a reset spring 92, the unlocking block 91 is slidably connected in the operating groove 42, one end of the reset spring 92 is connected to the unlocking block 91, and the other end is connected to the groove wall of the operating groove 42, and the unlocking block 91 is provided with an unlocking slope on the side facing the fan-shaped block 81. A guide groove 43 is provided through the connecting cylinder 4, and a guide arm 44 is provided on the unlocking block 91. The guide arm 44 is slidably connected in the guide groove 43 and extends outward from the connecting cylinder 4.

[0031] The structure is designed so that the unlocking block 91 can be moved by the guide arm 44. When the unlocking ramp contacts the limiting head 71, the limiting rod 7 can rotate until it rotates to a specified angle, at which point the first limiting plate 5 and the second limiting plate 6 can be pulled.

[0032] The invention is further configured such that: a slot 82 is provided on the side of the fan-shaped block 81 facing the unlocking block 91, and during the movement of the unlocking block 91, the unlocking ramp is inserted into the slot 82. This structural design can meet the movement stroke of the unlocking block 91, and can gradually push the limiting head 71 upward to flip through the unlocking ramp.

[0033] The present invention is further configured such that: the upper end of the unlocking block 91 is provided with a mounting base 93, and the mounting base 93 is provided with a pushing groove 94 and a pushing rod 95 on the side facing the fan-shaped block 81. The pushing rod 95 is slidably connected to the pushing groove 94 by a spring. When the unlocking block 91 moves toward the fan-shaped block 81, the limiting head 71 flips upward and abuts against the pushing rod 95.

[0034] The structure is designed such that when the limiting head 71 flips upward, it will abut against the abutting rod. As the unlocking block 91 moves gradually, the abutting rod will contract under force. When the limiting head 71 flips upward to the position where it is completely separated from the fan-shaped block 81, the abutting rod will retract outward under the action of the spring, thereby causing the limiting rod 7 to move to the outside of the connecting cylinder 4, thus completing the automatic separation function.

[0035] The invention is further configured such that: both the first limiting plate 5 and the second limiting plate 6 are provided with limiting rods 7 and positioning rods 52, which are respectively inserted into the two connecting cylinders 4. The length of the positioning rod 52 is less than the length of the limiting rod 7. This structure design utilizes the two-point fixing principle to ensure that the first limiting plate 5 and the second limiting plate 6 will not rotate or shift when installed on the connecting cylinder 4.

[0036] The invention is further configured such that a mutually cooperating locking structure is provided on the opposite side of the first limiting plate 5 and the second limiting plate 6. This locking structure is an existing slot and protrusion structure, which mainly ensures the firmness of the fixation between the first limiting plate 5 and the second limiting plate 6.

[0037] The present invention is further configured such that both the first limiting plate 5 and the second limiting plate 6 are convex structures.

[0038] The present invention is further configured such that nameplate grooves 13 are provided on the connector body 1, the first limiting plate 5, and the second limiting plate 6.

[0039] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
