[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0032] It should be noted that in this embodiment, the orientation or positional relationship indicated by "up", "down", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] In order to enable those skilled in the art of this technical field to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] Traditional power harnesses are usually made by combining commercial connectors with harnesses. During the implementation of the present application, the following technical problems are found:

[0035] First, existing connectors and harnesses only support electric motorcycles with about 80A and a speed of less than 70 Km / h. For a new generation of electric motorcycles that need to travel at a speed of more than 80 Km / h, they cannot meet the power output requirements.

[0036] Second, the existing connector fixing technology cannot maintain airtightness, and airtightness failure, air leakage, and water leakage will occur after long-term operation.

[0037] Third, the existing connector fixing latches are too sharp, and it is easy for users to scratch their fingers.

[0038] Fourth, the number of communication pins is too small, generally only 4 - 6 pins. It cannot meet the requirements of the power system of high-speed motorcycles.

[0039] Fifth, the air resistance caused by airtightness is small, and the vibration resistance of the connector is weak.

[0040] Sixth, the terminals of the male and female poles are parallel, which is likely to cause arcing and trigger dangerous accidents of personal injury, death, and property loss.

[0041] Therefore, based on the above situation, the present application proposes a connector and a power harness device applied to energy storage and electric motorcycles, which can improve the performance of the existing connector and harness device, thereby solving the above technical problems.

[0042] As Figure 1-8 shown, in this embodiment, a connector and a power harness device applied to energy storage and electric motorcycles are provided. The connector includes male and female plugging terminals 1, and the male and female plugging terminals 1 have plugging parts, so as to be connected to electrical components through the plugging parts to achieve power output.

[0043] The plug-in part includes a socket 11, signal pins 13, and a male terminal 12. The socket 11 can be adapted to the male and female plugs. Generally speaking, the socket 11 has certain protruding features and can be inserted into the slot of the male and female plugs, so as to achieve cooperation with the male and female plugs and closely fit with the male and female plugs to a certain extent, ensuring a certain degree of sealing and stability. It should be noted that the male and female plug-in terminals include male plug-in terminals and female plug-in terminals, and the corresponding male terminal and female terminal are provided. The male terminal is a pin structure, and the corresponding female terminal is a jack structure. The other structures of the male plug-in terminal and the female plug-in terminal are the same.

[0044] The socket 11 of the present application is rectangular, which can be square or rectangular. Based on the traditional wire harness device with an arc-shaped or semi-circular socket 11, without changing the external dimensions of the socket 11, by adjusting the structure of the socket 11, the outer wall area of the socket 11 can be increased, and at the same time, the accommodating space inside the socket 11 can be increased. In other words, under the same length and width conditions, the rectangular socket 11 has a larger internal capacity than the arc-shaped or semi-circular socket 11. Similarly, the area of the side wall of the rectangular socket 11 is also larger, which will make the contact surface between the socket 11 and the male and female plugs larger, increasing the bonding force between the two, thereby providing higher connection stability.

[0045] Two symmetrically arranged guiding grooves 111 are provided on the outer wall of the socket 11. Please refer to Figure 5 , according to the use feedback of traditional wire harnesses, too many guiding grooves 111 and groove depths are likely to cause excessive insertion and extraction forces of the male and female plugs, affecting daily use. Therefore, in the present application, the original four guiding grooves 111 are changed to two, and they are symmetrically arranged on both sides of the socket 11. The guiding grooves 111 are engaged with the guiding blocks on the male and female plugs. The guiding grooves 111 are rectangular grooves, and the groove depth is changed to 10 - 15 mm, reducing the groove depth on the original basis, so as to reduce the resistance during insertion and extraction and make the insertion and extraction more convenient.

[0046] Since the rectangular socket 11 increases the accommodating space inside the socket 11, more signal pins 13 can be arranged inside the socket 11. Compared with the original four to six pins, at least ten signal pins 13 can be arranged in the present application and are arranged in a rectangular array on one side of the socket 11, and are signal-connected to the cable 2, thereby greatly improving the flexibility of communication and meeting the power connection requirements of existing intelligent electric motorcycles.

[0047] In addition, the specification of the signal pin 13 is a diameter of 1.5 mm, which can support 5000 insertions and extractions, and is more stable and has better performance in use. At the same time, the male and female plug-in terminal 1 is a large current terminal supporting 100 - 120 amperes, which can meet the power requirements for the electric motorcycle to travel at a speed of more than 80 km / h.

[0048] The male terminal 12 is located inside the socket 11 and is electrically connected to the cable 2. The male terminal 12 includes a positive pin 122 and a negative pin 121. Please refer to Figure 4 , there is a certain height difference between the positive pin 122 and the negative pin 121. It can be that the negative pin 121 is higher and the positive pin 122 is lower; or the positive pin 122 is higher and the negative pin 121 is lower. As long as the ends of the two are not in the same plane, the arcing phenomenon during plugging and unplugging can be greatly reduced or even avoided, improving the safety of people and property.

[0049] In addition, please refer to Figure 2 and Figure 3 , the male-female pluggable terminal 1 of the present application further includes a fixing part 14 integrally formed by injection molding with the plugging part. After assembling the male-female pluggable terminal 1 with the cable 2 riveted to the plastic part and gluing and fixing it into a combined part, the above combined part is placed in the mold of the inner mold, and after synchronously fixing the correct wire outlet position of the wire in the mold, inner mold forming is carried out to form the fixing part 14.

[0050] The cable at the corresponding position of the fixing part 14 is bent, that is, the cable 2 at the tail of the male-female pluggable terminal 1 is bent. The bent area 21 of the cable 2 is located inside the fixing part 14 and is integrally connected with it. The formed inner mold product is subjected to secondary appearance forming, and the wire outlet position at the tail of the wire is accurately fixed and formed, that is, the forming part 15.

[0051] The male-female pluggable terminal 1 is formed in the above way, which can ensure the integrity of the product, and effectively protect the safety hazard brought by the damage of the cable 2 in the bent area 21 during the daily plugging and unplugging use of the plug. In addition, the integral injection molding method effectively protects the plugging part, the fixing part 14 and the forming part 15 to have good airtightness, and still has high airtightness after long-term operation.

[0052] In addition, a locking component 3 is also provided on the male-female pluggable terminal 1. After the socket 11 and the male-female plug are plugged in place, the locking component 3 locks with the male-female plug. It is pointed out above that the existing lock has no protection structure at the pressing part, and the sharp structure of the lock part is exposed, which is easy to scratch the finger when pressing. At the same time, the existing structure of the lock has a large pressure when pressing to unlock, and it is difficult to unlock; therefore, the present application realizes locking and unlocking through the lever principle, which is more in line with ergonomics and is more labor-saving and easy to use during pressing. Specifically, the locking component 3 of the present application includes a lock rod 31 hinged to the male-female pluggable terminal 1 in the middle. Please refer to Figure 5 and Figure 6, one end of the locking rod 31 has a fastening portion for locking with the male and female plug, and the other end of the locking rod 31 is provided with a pressing portion 32. Press the pressing portion 32 to unlock the fastening portion from the male and female plug. Of course, if the pressing portion 32 is released, the locking rod 31 can automatically reset under the action of the elastic member and complete the locking with the male and female plug.

[0053] On this basis, an inclined surface 321 inclined downward is provided at the tail of the pressing portion 32. The finger can directly contact the inclined surface 321 for pressing. At the same time, the tail of the pressing portion 32 is located above the locking rod 31 and at least covers the end of the locking rod 31, which can block the sharp part of the locking rod 31 and prevent the finger from directly contacting the locking rod 31, thereby preventing finger scratching. In order to further improve the matching degree between the pressing portion 32 and the finger and conform to ergonomics, the inclined surface 321 can be set as an arc surface matching the finger here.

[0054] Combining the above embodiments, the socket 11 of the present application is set as a rectangular socket 11, which can accommodate at least ten communication pins, greatly improving the flexibility of communication; the communication pins adopt a specification of 1.5 mm, support 5000 times of plugging and unplugging, and the male and female plug-in terminals 1 adopt large-current terminals, supporting a large current of 100 - 120 amperes, meeting the power requirements of intelligent electric motorcycles. At the same time, after the rectangular socket 11 is plugged with the male and female plug, the contact surface between the two is larger, the connection between the two is more stable, and the anti-vibration performance is strong; through the integrally injection-molded male and female plug-in terminals 1, its sealing performance is higher, without air leakage or water leakage, meeting the harsh use environment; at the same time, the redesigned lock assembly 3 is more comfortable and durable, conforming to the ergonomic design.

[0055] In addition, the present application also provides a power harness device, including the connector applied to energy storage and electric motorcycles in any of the above items. The male and female plug-in terminals 1 at both ends of the power harness device are connected by cables and are respectively used to connect the battery output end and the power output end, so that the energy storage device also has the excellent performance of the power harness device.

[0056] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0057] Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
