Description

Technical Field

[0001] The utility model relates to the technical field of line connection, in particular to a line connector for parallel connection of multiple digital generator sets. Background Art

[0002] Digital variable frequency generator is a new generator product field developed in recent years. The popularization of this product is mainly concentrated in small generator systems below 5 kilowatts.

[0003] With the continuous development of society, the demand for special vehicles such as ambulances and emergency satellite communications is increasing. With the continuous advancement of science and technology, more and more high-power equipment is being used in these special vehicles. Therefore, a single digital variable frequency generator can no longer meet the actual power requirements. In order to meet the actual power requirements, two or more digital variable frequency generators are usually used in parallel on special vehicles.

[0004] In the process of using two digital variable frequency generators in parallel, line connection is an indispensable link. The traditional wiring method is to wrap and tighten the metal wires exposed after removing the insulation of the two wires. The degree of tightening determines the quality of the wiring. If the degree of tightening is poor, it is extremely easy to generate electric sparks after power is turned on, causing fire and threatening the safety of users' lives and property. The winding connection of the two wires will be wrapped and tied tightly with insulating tape. After long-term use, the insulating tape is prone to aging, leaving the metal wires inside exposed to the air, which is prone to danger. At the same time, when the electrician connects the wires and metal wires when the generator line is in a power-off state, if the generator line is accidentally energized due to misoperation, it is inevitable that the electrician will be in danger when directly contacting the wires and metal wires, posing a threat to the electrician's life safety. In view of this, we propose a line connector for multi-machine parallel connection of digital generator sets. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-Figure 7 As shown, one of the purposes of this embodiment is to provide a line connector for connecting multiple digital generator sets in parallel, including a shell 1. The shell 1 is made of plastic with good insulation to prevent the connector from leaking and injuring people. Two fixed joints 13 are symmetrically fixed inside the shell 1. One end of the fixed joint 13 is fixedly connected to a fixed line 12. The other end of the fixed line 12 passes through one side of the shell 1 and extends out. When the line connector is used to connect two generator sets in parallel to an energy storage device, the ends of the two fixed lines 12 located outside the shell 1 are electrically connected to the input ends of the two generator sets, and the output ends of the two generator sets are electrically connected to the positive pole of the same energy storage device. Two movable joints 2 are symmetrically provided inside the shell 1. The two movable joints 2 The two fixed connectors 13 are respectively arranged at positions near the four corners inside the shell 1, and the two movable connectors 2 and the two fixed connectors 13 are arranged correspondingly. A connecting line 11 is provided inside the movable connector 2. The end of the connecting line 11 away from the fixed connector 13 passes through one side of the shell 1 and extends out. The ends of the two connecting lines 11 located outside the shell 1 are electrically connected to the negative pole of the same energy storage device. A conductive pile 21 is fixedly connected to the side of the movable connector 2 close to the fixed connector 13. The conductive pile 21, the fixed connector 13, and the movable connector 2 are all made of metal with good conductivity. When the conductive pile 21 is inserted into the interior of the fixed connector 13, a passage is formed between the connecting line 11 and the fixed line 12, so that the two generator sets can be connected in parallel to the same energy storage device circuit.

[0030] A clamping mechanism 3 is provided on the side where the two movable joints 2 are close to each other, and two displacement mechanisms 4 are correspondingly provided between the two clamping mechanisms 3. When the electrician performs wiring operations, the two displacement mechanisms 4 simultaneously push the corresponding clamping mechanism 3 close to the connecting line 11, and the clamping mechanism 3 clamps one end of the connecting line 11 inside the movable joint 2, and can simultaneously fix the two connecting lines 11 inside the corresponding movable joints 2, thereby improving wiring efficiency. At this time, the displacement mechanism 4 drives the movable joint 2 close to the fixed joint 13, so that the conductive pile 21 is inserted into the corresponding fixed joint 13 to complete the wiring. Before the conductive pile 21 is inserted into the fixed joint 13, the movable joint 2 is in a non-energized working state, thereby improving the safety of the electrician when inserting the connecting line 11 into the movable joint 2.

[0031] In order to help the electrician fix one end of the connecting line 11 inside the corresponding movable joint 2, the structure of the clamping mechanism 3 and the partial structure of the displacement mechanism 4 are detailed below. Figure 2 、 Figure 3 and Figure 4 A movable groove 25 is provided on one side of the movable joint 2, and the movable groove 25 is communicated with the interior of the movable joint 2. The clamping mechanism 3 includes a clamping rod 31 slidably arranged inside the movable groove 25. The clamping rod 31 can only move horizontally along the inner wall of the movable groove 25. One end of the clamping rod 31 extends to the interior of the movable joint 2 and contacts the connecting line 11. The other end of the clamping rod 31 is fixedly connected to an end plate 32. A second spring 33 sleeved on the clamping rod 31 is provided between the end plate 32 and the movable joint 2. The second spring 33 is used to limit the position of the end plate 32 and the clamping rod 31 to prevent the clamping rod 31 from entering the interior of the movable joint 2 before the connecting line 11 is inserted into the movable joint 2, causing the clamping rod 31 to hinder the electrician from inserting the connecting line 11 into the interior of the movable joint 2. Figure 5 and Figure 6The displacement mechanism 4 includes a mounting cylinder 41 fixedly arranged inside the housing 1, a screw rod 42 is rotatably arranged inside the mounting cylinder 41, a nut 44 is threadedly connected to the screw rod 42, and the nut 44 is slidably arranged inside the mounting cylinder 41. The side wall of the mounting cylinder 41 is provided with a transverse groove 48 and a vertical groove 49. The transverse groove 48 and the vertical groove 49 are spliced ​​to form an L-shaped structure. The nut 44 and the expansion disk 46 are fixedly connected by a slider 45. When the slider 45 moves, it slides in the transverse groove 48 and the vertical groove 49. The expansion disk 46 is slidably sleeved on the outside of the mounting cylinder 41, and the expansion disk 46 contacts the side of the end plate 32 away from the movable joint 2. The electrician inserts one end of the connecting line 11 into the movable joint 2. After the inside of the joint 2 is rotated, the screw rod 42 is rotated, and the threaded connection between the screw rod 42 and the nut 44 is used to make the nut 44 drive the slider 45 along the inner wall of the horizontal groove 48 close to the movable joint 2. The moving slider 45 drives the expansion disk 46 to move synchronously, and the expansion disk 46 pushes the end plate 32 close to the movable joint 2. The moving end plate 32 drives the clamping rod 31 to move, and the second spring 33 elastically contracts. When the slider 45 contacts one end of the vertical groove 49 connected to the horizontal groove 48, the clamping rod 31 cooperates with the inner wall of the movable joint 2 to clamp one end of the connecting line 11 to the inside of the movable joint 2, thereby fixing the connecting line 11 and the movable joint 2, and connecting the generator corresponding to the connecting line 11 to the circuit.

[0032] In order to help the electrician fix one end of the two connecting lines 11 at the same time inside the corresponding movable joint 2, refer to Figure 7 A rotating rod 14 is provided for rotation inside the housing 1. One end of the rotating rod 14 passes through the housing 1 and is fixedly connected to a knob. A driving bevel gear 15 is coaxially fixedly connected to the side wall of the rotating rod 14. The end of the screw rod 42 away from the movable joint 2 is coaxially fixedly connected to a driven bevel gear 43. The two driven bevel gears 43 are respectively meshed and connected to the opposite sides of the driving bevel gear 15. When the electrician holds the knob and twists the rotating rod 14, the rotating rod 14 drives the driving bevel gear 15 to rotate. Through the meshing transmission of the two driven bevel gears 43 and the driving bevel gear 15, the two driven bevel gears 43 respectively drive the two screw rods 42 to rotate synchronously, thereby fixing one end of the two connecting lines 11 at the same time inside the corresponding movable joint 2 to improve the wiring efficiency of the electrician.

[0033] In order to fix one end of the connecting line 11 inside the corresponding fixed joint 13 and insert one end of the conductive pile 21 into the corresponding fixed joint 13, the remaining components of the displacement mechanism 4 are refined below. The expansion disk 46 is coaxially fixedly connected to the side of the movable joint 2 with the transmission gear 47, and the side of the movable joint 2 close to the expansion disk 46 is fixedly connected to the rack 24. One side of the rack 24 is in sliding contact with the inner wall of the shell 1. When the expansion disk 46 pushes the end plate 32 close to the movable joint 2, the transmission gear 47 engages with the rack 24. When one end of the connecting line 11 is fixed inside the corresponding fixed joint 13, the slider 45 contacts one end of the vertical slot 49 connected to the horizontal slot 48, and the expansion disk 46 drives the transmission gear 47 to move to the rack 2 4, and the transmission gear 47 is engaged with the rack 24. At this time, the electrician continues to twist the rotating rod 14 to rotate the screw rod 42. The screw rod 42 drives the slider 45 along the inner wall of the horizontal groove 48 to rotate into the interior of the vertical groove 49. The rotating slider 45 drives the expansion disk 46 and the transmission gear 47 to rotate synchronously. Through the meshing transmission of the transmission gear 47 and the rack 24, the rack 24 drives the movable joint 2 to approach the fixed joint 13 until the slider 45 rotates to the end of the vertical groove 49 away from the horizontal groove 48. At this time, the moving movable joint 2 drives one end of the conductive pile 21 to insert into the interior of the fixed joint 13. The conductive pile 21 and the fixed joint 13 are in contact, and current can flow between the conductive pile 21 and the fixed joint 13, thereby connecting the two generator sets in parallel to the circuit.

[0034] There is a gap between the end plate 32 and the transmission gear 47. When the movable joint 2 approaches the fixed joint 13, the end plate 32 is driven to move synchronously. The moving end plate 32 slides along the side of the expansion disk 46 close to the movable joint 2. When one end of the conductive pile 21 is inserted into the interior of the fixed joint 13, the end plate 32 still does not contact the transmission gear 47 on the expansion disk 46, thereby ensuring the normal rotation of the transmission gear 47.

[0035] A sleeve 22 is slidingly sleeved on the conductive pile 21, and the sleeve 22 is fixedly arranged inside the housing 1. The sleeve 22 guides the conductive pile 21, thereby improving the stability of the conductive pile 21 when it moves horizontally. A first spring 23 sleeved on the conductive pile 21 is provided between the movable joint 2 and the sleeve 22. The first spring 23 is used to limit the position of the movable joint 2, the conductive pile 21 and the rack 24. When the connector is in an unpowered working state, the conductive pile 21 is prevented from contacting the fixed joint 13, ensuring the safety of the electrician when inserting one end of the connecting line 11 into the movable joint 2. At the same time, when the transmission gear 47 moves to the upper side of the rack 24, it is ensured that the transmission gear 47 and the rack 24 can be stably engaged. When the movable joint 2 drives the conductive pile 21 close to the fixed joint 13, the distance between the movable joint 2 and the sleeve 22 is shortened, and the first spring 23 elastically contracts, so that the first spring 23 will not hinder the movement of the fixed joint 13 under human action.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
