Description

Technical Field

[0001] The utility model relates to the technical field of cable interfaces, and specifically relates to a tooling cable quick-connection interface. Background Technique

[0002] A cable interface is a device used to dock two cables, so as to form a longer cable by combining the two cables, and can also realize signal transmission between the two cables, and is widely used in various electrical machinery and equipment.

[0003] In the prior art, Chinese Patent No. CN118156901A discloses an anti-disengagement structure and assembly method for an ignition cable interface. The anti-disengagement structure of the ignition cable interface is composed of a bushing, a nut, a spring, a high-voltage ignition wire, a retaining ring, a rubber gasket, an insulating tube and a jack. The high-voltage ignition wire sequentially passes through the bushing, the spring, the retaining ring, the rubber gasket and the insulating tube. First, the tail end of the insulating tube is screwed into the concave groove inside the bushing through threads, then the high-voltage ignition wire is crimped with the jack, and finally the jack is screwed into the insulating tube to complete the assembly of the anti-disengagement interface of the ignition cable. Through the mutual limitation between the parts of each interface of the ignition cable, an anti-disengagement interface design is formed, which solves the problem of difficult assembly caused by the separation of interface parts during the disassembly and assembly of the ignition cable, and improves the reliability of the product.

[0004] The above device fixes the cable through a nut to achieve the docking purpose. However, in the actual use process, the threaded method requires working days to rotate during docking and removal. In case of jamming, it is very difficult to disassemble. Therefore, the overall interface is not convenient for quick installation and disassembly. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tooling cable quick-connection interface to solve the problem of inconvenient disassembly and quick disassembly proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tooling cable quick-connection interface, including cable bodies to be docked. First joints and second joints are respectively installed at the tops of the two cable bodies, and further includes:

[0007] A copper docking column is fixedly installed inside the first joint, and the docking column is inserted and electrically connected with a docking hole opened at the front end of the second joint;

[0008] Positioning grooves are opened on the upper and lower sides of the first joint, and square-structured positioning blocks are installed on the upper and lower sides of the second joint. A fixed buckle for quick disassembly of the joint is fixedly installed on the side of the positioning block, and a clamping groove is opened inside the first joint;

[0009] A sealing mechanism for waterproofing after connection is provided at the front end of the second joint.

[0010] Preferably, the positioning groove and the positioning block are inserted and engaged with each other, and the fixing buckle and the engaging groove are engaged and fixed with each other.

[0011] Preferably, a limiting post is fixedly installed inside the second joint, and the limiting post and the positioning block penetrate and slide with each other.

[0012] Preferably, a return spring for pushing the positioning block to reset upward is installed outside the lower end of the limiting post, and a friction plate with a rough surface is fixedly installed on the side surface of the positioning block.

[0013] Preferably, the sealing mechanism includes a sealing ring fixedly installed on the outer surface of the second joint and an extrusion airbag installed inside the second joint. The sealing ring is made of hollow rubber material, and a communication structure is formed between the sealing ring and the extrusion airbag by means of a conveying hose.

[0014] Preferably, the extrusion airbag is fixedly installed on the upper surface of the extrusion plate, and the extrusion plate is fixedly connected to the positioning block through a connecting rod above it.

[0015] Preferably, connecting pieces are fixedly installed on the exteriors of both the first joint and the second joint, and the connecting pieces are fixedly installed with the cable main body through external fixing clamps.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The quick-connect interface of the tooling cable adopts a new structural design, and the specific content is as follows:

[0017] 1. The first joint and the second joint are fixed by the engagement between the fixing buckle and the engaging groove, so as to realize the docking operation. This operation does not require the use of a complex fixing structure, and only needs to press the positioning block, so the quick disassembly and quick installation of the joint can be realized.

[0018] Furthermore, the positions of the positioning block and the positioning groove correspond to each other. During docking, only by engaging the positioning block and the positioning groove can ensure correct connection and avoid repeated attempts to insert during docking.

[0019] Furthermore, a friction plate is fixedly installed on the outer side of the side surface of the positioning block. The friction force is generated between the friction plate and the inner wall of the positioning groove, so as to avoid the interface from loosening due to small accidental touches during use and improve the firmness of the connection.

[0020] 2. After the positioning block moves upward, it drives the extrusion plate to move synchronously through the connecting rod, so that the extrusion plate squeezes the extrusion airbag. At this time, the air in the extrusion airbag is transported to the sealing ring through the delivery hose, causing the sealing ring to expand and fit the inner wall of the first joint, achieving the effect of sealing and waterproofing. Moreover, the sealing ring can be inflated and deflated cyclically, which can prevent deformation after long-term use and affect the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 4, in order to solve the problem that traditional devices are not convenient for quick connection, the following technical solutions are provided, and specifically disclosed: the cable main body 1 to be docked, the top ends of the two cable main bodies 1 are respectively installed with a first connector 2 and a second connector 3. Inside the first connector 2, a copper docking post 6 is fixedly installed, and the docking post 6 is inserted and docked with a docking hole 7 opened at the front end of the second connector 3 and is electrically connected. Positioning grooves 8 are opened on both the upper and lower sides of the first connector 2, and square-shaped positioning blocks 9 are installed on both the upper and lower sides of the second connector 3. A fixed buckle 10 for quick disassembly of the connector is fixedly installed on the side of the positioning block 9. And a clamping groove 11 is opened inside the first connector 2. The positioning groove 8 and the positioning block 9 are correspondingly inserted and clamped, and the fixed buckle 10 and the clamping groove 11 are clamped and fixed to each other. A limiting post 12 is fixedly installed inside the second connector 3, and the limiting post 12 penetrates and slides with the positioning block 9. A return spring 13 for pushing the positioning block 9 to reset upward is installed outside the lower end of the limiting post 12. And a friction plate 14 with a rough surface is fixedly installed on the side of the positioning block 9. Connection pieces 4 are fixedly installed on the outsides of both the first connector 2 and the second connector 3, and the connection pieces 4 are fixedly installed with the cable main body 1 through an external fixed hoop 5.

[0031] During use, first, the two cable main bodies 1 to be docked are respectively installed with the first connector 2 and the second connector 3. During installation, the cable main body 1 is inserted into the connection piece 4, and then the connection piece 4 and the cable main body 1 are fixedly connected by using the fixed hoop 5. When docking, the first connector 2 and the second connector 3 are aligned and inserted into each other. At this time, the docking post 6 correspondingly inserts into the docking hole 7 to realize current flow. During docking, the positioning block 9 inserts into the positioning groove 8 to avoid misalignment. And when inserting, the positioning block 9 is pressed, and after insertion is completed, the positioning block 9 is released. At this time, the positioning block 9 moves outward under the elastic action of the return spring 13 and the guiding action of the limiting post 12. During the movement of the positioning block 9, the fixed buckle 10 is driven to move synchronously. Finally, the fixed buckle 10 enters the clamping groove 11 to form a clamping structure, fixing the first connector 2 and the second connector 3. The friction plate 14 can increase the friction between the positioning block 9 and the inner wall of the positioning groove 8, thus avoiding loosening caused by accidental touch.

[0032] Embodiment Two: Please refer to Figure 5 , in order to solve the problem of poor sealing effect of traditional devices, the following technical solutions are provided, and specifically disclosed: a sealing mechanism for waterproofing after connection is provided at the front end of the second connector 3. The sealing mechanism includes a sealing ring 15 fixedly installed on the outer surface of the second connector 3 and an extrusion airbag 16 installed inside the second connector 3.

[0033] After docking is completed, the sealing ring 15 fits with the inner wall of the first connector 2 to achieve the purpose of sealing and waterproofing, so that the interface can be used with confidence even outdoors.

[0034] Embodiment Three: Please refer toFigures 5 - 7 , in order to solve the problem of poor sealing and waterproofing effect of traditional devices, the following technical solutions are provided in this embodiment, and specifically disclosed: The sealing ring 15 is made of hollow rubber material, and a communication structure is formed between the sealing ring 15 and the extrusion airbag 16 by using a delivery hose 17. The extrusion airbag 16 is fixedly installed on the upper surface of the extrusion plate 18, and the extrusion plate 18 is fixedly connected to the positioning block 9 through a connecting rod 19 above it.

[0035] After the docking is completed, the positioning block 9 moves upward. During the moving process, the extrusion plate 18 is driven to move synchronously through the connecting rod 19. At this time, the extrusion airbag 16 is extruded by the extrusion plate 18. When the extrusion airbag 16 is extruded, the air inside it is filled into the sealing ring 15 through the delivery hose 17, causing the sealing ring 15 to expand, so as to achieve a better sealing effect. At the same time, after disassembly, the sealing ring 15 shrinks, avoiding deformation due to long-term extrusion and affecting the subsequent sealing and waterproofing effect.
