Description

Technical Field

[0001] The present invention relates to the technical field of wire harness connectors, and particularly to a high-voltage and low-voltage wire harness connector for energy storage of new energy pure electric vehicles. Background Art

[0002] A connector is a component that people often come into contact with, and its function is very simple: it bridges the gap in a circuit where it is blocked or in an isolated circuit, enabling current to flow and the circuit to achieve its intended function. Connectors are indispensable components in electronic devices. Looking along the path of current flow, you will always find one or more connectors. The forms and structures of connectors vary widely. With different application objects, frequencies, powers, application environments, etc., there are various forms of connectors. For example, high-voltage and low-voltage wire harness connectors for energy storage in electric vehicles, connectors for lighting on the sports field, connectors for hard disk drives, and connectors for igniting rockets.

[0003] In order to solve the problem that it is relatively inconvenient to plug and unplug the male and female connectors of the existing wire harness connectors, Chinese Patent No. CN109326927B discloses a high-voltage and low-voltage wire harness connector for energy storage of new energy pure electric vehicles, which includes a wire positioning ring, a locking cover, a T-shaped slider, a positioning shaft, a top-holding plug-in frame, a positioning block, and a T-shaped sliding frame; the female head is integrally rectangular, and a disc-shaped wiring seat protrudes and supports on its rear end face. A locking cover is screwed onto this disc-shaped wiring seat, and a square slot is recessed and opened on the front end face of the female head. Three power connection sockets are supported in a triangular array inside this square slot; a positioning frame is injection-molded on the top end face of the female head. The front end of this positioning frame is open, and a stop plate is bent inward at the leading end of each of its left and right support rods, and the T-shaped slider is slidably placed inside the positioning frame. Although the existing technical problems are solved, there are still the following problems:

[0004] In this technical solution, after docking the male and female heads and fixing them, the steps are relatively complex and inconvenient to use. Therefore, corresponding improvements are made to address this problem. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a high-voltage and low-voltage wire harness connector for energy storage of new energy pure electric vehicles.

[0006] A new energy pure electric vehicle energy storage high and low voltage wire harness connector proposed by the present invention includes a female head and a male head that are plugged together. A rotating shaft is fixed on the outer end face of the top of the male head, and a cover plate is rotatably connected to the rotating shaft. Inlet pipes are respectively arranged at the opposite ends of the female head and the male head. First notches are respectively opened on both sides of the cover plate. A pair of symmetrically distributed front and rear clamping plates that are elastically connected to the male head are arranged on the top of the male head. One end inner wall of the first notch is provided with a triangular block, and a docking port for inserting the end of the clamping plate is left above the triangular block. An extension part is arranged at the end of the clamping plate far away from the triangular block; the two wire harnesses to be connected are respectively inserted into the two inlet pipes, and the two wire harnesses are respectively connected to the female head and the male head. After the connection is completed, the female head and the male head are plugged together, and then the cover plate is rotated to be combined with the female head. During this process, when the inclined surface below the triangular block contacts the end of the clamping plate, the clamping plate will be pushed to the side away from the triangular block. When the cover plate is completely closed, under the action of elastic force, the clamping plate will move back, and the end of the clamping plate will be inserted into the docking port, so as to directly fix the cover plate, and thus directly fix between the female head and the male head through the cover plate, avoiding the separation between the female head and the male head. And by pulling the clamping plate to the side away from the triangular block through the extension part, the fixation of the clamping plate to the cover plate can be released, and then the cover plate can be directly rotated upward to open.

[0007] Preferably, a guide rod is inserted at the end of the clamping plate far away from the triangular block, and a fixed block is fixed at the other end of the guide rod. The fixed block is fixed on the male head. A first spring is sleeved on the guide rod, and both ends of the first spring are respectively fixedly connected to the fixed block and the clamping plate; the guide rod is used to limit the lateral movement of the clamping plate, and the first spring can be used to drive the clamping plate to move back.

[0008] Preferably, sliding openings are respectively opened on the two inner side surfaces of the top of the male head, and the two clamping plates are fixedly connected by a plurality of connecting columns. The connecting columns pass through the sliding openings;

[0009] The two clamping plates are fixed together by the connecting columns, so that the two clamping plates can move synchronously, improving stability.

[0010] Preferably, a U-shaped sliding frame is jointly fixed between the two clamping plates, and a sliding groove is opened at the bottom of the male head. The U-shaped sliding frame forms a sliding fit with the male head through the sliding groove; when an upward pulling force is applied to the clamping plate, the two clamping plates are stabilized by the U-shaped sliding frame, so as to avoid damage to the clamping plate due to external force.

[0011] Preferably, a pair of connecting rods distributed front and back are fixed to the side of the U-shaped carriage. A column rod is fixed to the inner side of the connecting rod. Second notches for the column rod to move are respectively formed on both sides of the cover plate. An arc-shaped portion capable of contacting the column rod is provided at one end of the second notch away from the triangular block. When the clamping plate is pulled to one side, the clamping plate synchronously drives the U-shaped carriage and the connecting rod to move. When the end of the clamping plate completely moves out of the docking port, the column rod just contacts the arc-shaped portion, and then the arc surface of the arc-shaped portion is pushed by the second notch, so as to jack up the cover plate and quickly open the cover plate.

[0012] Preferably, a pair of socket sleeves distributed up and down are provided on the inlet pipe. Plug plates are inserted into the socket sleeves. Arc-shaped clamping blocks are respectively fixed to one ends of the two plug plates facing each other. An elastic connection is formed between the plug plate and the socket sleeve. The plug plate is connected with a transmission assembly. By the action of the transmission assembly on the plug plate, the two plug plates will approach each other along the direction of the socket sleeve, and the wire harness is clamped and fixed by the two clamping blocks.

[0013] Preferably, the transmission assembly includes a threaded sleeve threadedly connected to the inlet pipe. A sleeve disk capable of moving horizontally is sleeved on the inlet pipe. The sleeve disk is located between the threaded sleeve and the socket sleeve. An inclined edge abutting against the plug plate is provided on one side of the sleeve disk close to the plug plate. When the threaded sleeve is rotated, the threaded sleeve pushes the sleeve disk to the side close to the plug plate. The inclined edge on the sleeve disk acts on the top end of the plug plate to apply pressure to the plug plate, so that the two clamping blocks approach each other.

[0014] Preferably, a pair of positioning columns distributed up and down are provided on one side of the socket sleeve close to the sleeve disk. A pair of positioning holes for the positioning columns to pass through are formed on the sleeve disk. The sleeve disk is horizontally limited and moved through the cooperation of the positioning columns and the positioning holes.

[0015] Preferably, guide sleeves are respectively fixed to both sides of the socket sleeve. Guide columns are respectively fixed to both sides of the plug plate. The bottom ends of the guide columns pass through a corresponding guide sleeve. A second spring is sleeved on the guide column. Both ends of the second spring are fixedly connected with the guide sleeve and the plug plate respectively. When the threaded sleeve is rotated in the reverse direction, the plug plate moves in the reset direction under the elastic force of the second spring, so that the two clamping blocks loosen the clamping and fixing of the wire harness.

[0016] Compared with the prior art, the present invention provides a high-low voltage wire harness connector for energy storage of a new energy pure electric vehicle, and has the following beneficial effects:

[0017] 1. A high - and low - voltage wire harness connector for energy storage of a new - energy pure - electric vehicle. After inserting the female head and the male head together by setting a cover plate, then rotating the cover plate to close it onto the female head. During this process, when the inclined surface below the triangular block contacts the end of the clamping plate, the clamping plate will be pushed to the side away from the triangular block. And when the cover plate is completely closed, under the elastic force, the clamping plate will move back, and the end of the clamping plate will insert into the docking port, thus directly fixing the cover plate. In this way, the cover plate directly fixes the female head and the male head, with a simple structure and convenient operation.

[0018] 2. A high - and low - voltage wire harness connector for energy storage of a new - energy pure - electric vehicle. By setting a U - shaped sliding frame, when the clamping plate is subjected to an upward pulling force, the U - shaped sliding frame stabilizes the two clamping plates, thus preventing the clamping plate from being damaged by external forces.

[0019] 3. A high - and low - voltage wire harness connector for energy storage of a new - energy pure - electric vehicle. By setting a column rod and an arc part, when pulling the clamping plate to one side, the clamping plate synchronously drives the U - shaped sliding frame and the connecting rod to move. When the end of the clamping plate completely moves out of the docking port, the column rod just contacts the arc part, and then the arc surface of the arc part is pushed by the second notch, thus lifting the cover plate upward to quickly open the cover plate.

[0020] 4. A high - and low - voltage wire harness connector for energy storage of a new - energy pure - electric vehicle. By setting clamping blocks, rotating the threaded sleeve, the threaded sleeve pushes the sleeve plate towards the side close to the insertion plate. The inclined edge on the sleeve plate acts on the top of the insertion plate, applying pressure to the insertion plate, making the two clamping blocks approach each other to clamp and fix the wire harness.
