Description

Technical Field

[0001] The invention relates to the technical field of wire harness connection, in particular to a protective electric motorcycle wire harness connection device. Background Art

[0002] Protective electric motorcycles are those that pay special attention to safety and protection performance during the design and manufacturing process. The electric motorcycle wiring harness connection device is an important part of the electric motorcycle electrical system. It is a series of wires and connectors used to connect various electrical components (such as batteries, motor controllers, sensors, dashboards, lamps, etc.). The main function of the wiring harness is to transmit power and signals to ensure communication and functional coordination between various parts of the vehicle.

[0003] The patent with announcement number CN220253652U discloses an electric vehicle wiring harness assembly, specifically, an electric vehicle wiring harness assembly for preventing the connection from loosening, including a wiring harness assembly, the wiring harness assembly including a cable assembly, a connector assembly, a plug assembly and a limit assembly, the connector assembly and the plug assembly are respectively arranged at both ends of the cable assembly, two limit assemblies are respectively arranged on the connector assembly and the plug assembly, the limit assembly includes a shell, a spring, a slide bar, a connecting plate and a plug block, and three springs are installed on the inner wall of one side of the shell by bolts; when the wiring harness assembly is connected together, the connecting plate is pulled so that the connecting plate is inserted into the groove on the corresponding connector or the installation groove on the plug, and the plug block is inserted into the limiting hole, and then the connecting plate is subjected to a pulling force under the action of the spring, so that the connecting plate, the plug block and other structures are firmly fixed in the groove or the installation groove to prevent the wiring harness from shaking and the connector from loosening and falling off.

[0004] When connecting the wiring harness, it is not only important to ensure a stable connection between the male and female connectors, but also the connection between the male and female connectors and the wiring harness. The wiring harness connecting the electric vehicle to the male and female connectors often has more than one wire, and it is often only connected to the part it should be connected to, such as power supply, sensor, lighting, power output, heat dissipation and other components. Because several wiring harnesses are cut to the same length when connected, and because several wiring harnesses, male and female connectors are generally not too large, this leads to the following situations when connecting several wiring harnesses to male or female connectors:

[0005] 1. Insert all the wiring harnesses at once: It is easy to cause the wiring harnesses to be misaligned, because different wiring harnesses have different functions, which can easily lead to subsequent short circuits or even direct unusability.

[0006] 2. Insert the wiring harnesses in sequence: Because the wiring harnesses have the same length and the male or female connector does not have the function of pre-fixing the already inserted wiring harnesses, it is easy to inadvertently cause the previously inserted wiring harness to loosen when inserting a new wiring harness, which will cause the wiring harness to fail to form an effective circuit connection with the contact pieces on the male and female connectors, and may still cause a short circuit or become unusable.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See also Figure 1-Figure 12A protective electric motorcycle wiring harness connection device comprises a male head 1 and a female head 2 respectively connected with a plurality of connection harnesses 5, the outer walls of the male head 1 and the female head 2 are respectively fixedly connected with a clamping strip 3 and a clamping block 4, a side of the female head 2 close to the male head 1 is provided with a plurality of female holes 202 matching the male head 1, the ends of the male head 1 and the female head 2 away from each other are both provided with an installation cavity 201, the rear ends of the plurality of female holes 202 are all located in the installation cavity 201, and the outer walls of the rear ends of the plurality of female holes 202 are all connected with a plurality of connecting components, and the other ends of the plurality of connecting components are simultaneously connected with a supporting block 15, and the other end of the supporting block 15 is connected to An anti-slip assembly is connected, the other end of the anti-slip assembly is connected to a pre-limiting assembly, the other end of the pre-limiting assembly is connected to a sealing assembly, the outer wall of the support block 15, the outer side of the pre-limiting assembly and the outer side of the sealing assembly are all slidably connected to the inner wall of the installation cavity 201, a number of connecting harnesses 5 are matched with the inner side of the sealing assembly, the inner side of the pre-limiting assembly and the side wall of the support block 15, and a number of connecting harnesses 5 are respectively matched with a number of connecting assemblies, the inner wall of the installation cavity 201 away from the mother hole 202 is connected to a number of supporting assemblies, and the other ends of the several supporting assemblies are connected to one end of the sealing assembly away from the pre-limiting assembly.

[0038] like Figures 1 to 12 As shown, the protective electric motorcycle wiring harness connection device of the present invention can be connected to the connecting harness 5 with the male connector 1 or the female connector 2 according to the following steps:

[0039] 1. When the male connector 1 or the female connector 2 is not connected to the connecting harness 5, the connecting component on the supporting block 15 is not connected to and does not contact the female hole 202.

[0040] 2. At the same time, due to the function of the anti-drop assembly, the support block 15 will also push the pre-limiting assembly toward the outside of the installation cavity 201, so that the pre-limiting assembly and the support assembly are also out of contact.

[0041] 3. Because the pre-limiting component is located outside the installation cavity 201, the sealing component will naturally expand upward due to its own elasticity, and therefore, without the action of a large external force, the pre-limiting component will not naturally retract into the installation cavity 201.

[0042] 4. Also because the pre-limiting component is located outside the installation cavity 201, when it is necessary to connect the connecting harness 5 to the female connector 2, it is only necessary to first remove a portion of the insulation skin of the copper wire part at the front end of the connecting harness 5, and then insert the first connecting harness 5 into the pre-limiting component, and pass the exposed copper wire part through the pre-limiting component so that this part of the copper wire is located between the support block 15 and the pre-limiting component, that is, located in the area of ​​the anti-slip component, and then rotate the pre-limiting component to one side by a certain angle.

[0043] 5. When the pre-limiting assembly rotates, the first connecting harness 5 is squeezed and limited by the pre-limiting assembly, so that the connecting harness 5 will not fall off without a large external pulling force.

[0044] 6. Similarly, when the pre-limiting component rotates, the pre-limiting component will expose the installation area of ​​the second connecting harness 5. At this time, according to step 4, the second and other remaining connecting harnesses 5 are installed in the pre-limiting component in sequence, and pre-fixed by the pre-limiting component to avoid falling off. And because they are installed in sequence, there will be no misalignment.

[0045] 7. After all the connecting harnesses 5 are fixed by the pre-limiting assembly, the installer manually presses the pre-limiting assembly into the installation cavity 201 instantly.

[0046] 8. When the pre-limiting component is pressed into the installation cavity 201, the sealing component on the pre-limiting component is against the inner wall of the installation cavity 201 and squeezed downward until the pre-limiting component is completely located in the installation cavity 201 (that is, when an effective circuit connection is formed between the connecting component and the mother hole 202), and when the pre-limiting component stops moving, the sealing component can also just wrap the several connecting wire harnesses 5 located in the pre-limiting component therein, thereby increasing the sealing effect between the installation cavity 201 and the external environment and reducing the possibility of dust falling.

[0047] 9. Similarly, when the pre-limiting component is pressed into the installation cavity 201, the pre-limiting component will squeeze through several supporting components, and after completely passing through the supporting components (that is, when an effective circuit connection is formed between the connecting component and the mother hole 202), the pre-limiting component is located exactly between the supporting component and the mother hole 202, and can then be pressed tightly in the installation cavity 201 by the supporting component, making it less likely to loosen or fall off.

[0048] 10. Similarly, when the pre-limiting component is pressed into the installation cavity 201, the anti-dropping component will be squeezed by force and then received in the pre-limiting component. After the pre-limiting component is tightly limited by the supporting component, the anti-dropping component will not expand or contract.

[0049] 11. Through the above steps 1-10, the problem that the current connection harness 5 is easily short-circuited or cannot be used directly when connected and fixed between the male connector 1 and the female connector 2 can be solved. Then, the male connector 1 and the female connector 2 can be fixed by the clamping strip 3 and the clamping block 4 on the male connector 1 and the female connector 2.

[0050] Special mention should be made here:

[0051] 1. The internal structures of the male connector 1 and the female connector 2 are the same. Therefore, all the above-mentioned and subsequent structures and connection relationships located in the internal mounting cavity 201 of the female connector 2 are also applicable to the male connector 1. The only difference is that the male connector 1 is protruding relative to the female hole 202 of the female connector 2. Here, it is only necessary to protrude the female hole 202 inside the male connector 1 inward, which can be also applied to the above-mentioned and subsequent embodiments.

[0052] 2. Because the male connector 1 and the female connector 2 of the electric vehicle connection harness 5 are generally not too large, it does not take much effort to press the pre-limiting component into the installation cavity 201.

[0053] 3. The card strip 3 and the card block 4 on the male connector 1 and the female connector 2 are very mature technologies, so they will not be described in detail here.

[0054] As a preferred embodiment of the present invention, the connecting component includes a connecting copper ring 10, a deformable copper ring 16 and a copper column 17. The side wall of the support block 15 is provided with a plurality of placement openings 151. One end of the connecting copper ring 10 is fixedly connected to one end of the mother hole 202 located in the installation cavity 201. The other end of the connecting copper ring 10 is sleeved and slidably connected to the outer wall of the copper column 17. The other end of the copper column 17 is fixedly connected to one end of the deformable copper ring 16. The outer wall of the other end of the deformable copper ring 16 is respectively fixedly connected to the inner walls of the plurality of placement openings 151. The end of the connecting wiring harness 5 located in the installation cavity 201 is located in the deformable copper ring 16, and the outer wall of the connecting wiring harness 5 is slidably connected to the inner wall of the deformable copper ring 16.

[0055] More specifically, when it is necessary to ensure the normal circuit connection between the connecting wiring harness 5 in the support block 15 and the female hole 202, as the connecting wiring harness 5 is fixed by the pre-limiting assembly, and the pre-limiting assembly and the connecting wiring harness 5 are manually pushed into the deformable copper ring 16 in the placement port 151 (because the distance between the support block 15 and the pre-limiting assembly is shortened, the copper wire portion of the connecting wiring harness 5 originally located between the support block 15 and the pre-limiting assembly can be just inserted into the deformable copper ring 16 in the placement port 151), at this time, the copper wire of the connecting wiring harness 5 is squeezed tightly in the deformable copper ring 16, and then an effective circuit connection can be formed between the deformable copper ring 16, and then, when power or signal is actually transmitted to the electric vehicle in the future, the deformable copper ring 16 can transmit this part of the electric energy or wiring harness to the female hole 202 through the copper column 17 and the connecting copper ring 10, and finally form a circuit from the female hole 202 and the needle on the male head 1.

[0056] As a preferred solution of the present invention, the anti-slip assembly includes a sliding column 20, an anti-slip plate 21, a push spring 22 and a plurality of connecting rods 14, one end of the sliding column 20, the push spring 22 and the plurality of connecting rods 14 are fixedly connected to the end of the support block 15 away from the mother hole 202, the other end of the sliding column 20 is fixedly connected to one end of the anti-slip plate 21, and the anti-slip plate 21, the push spring 22 and the plurality of connecting rods 14 are connected to the pre-limiting assembly at one end away from the support block 15.

[0057] More specifically, when not installed, due to the action of the push spring 22, there will be a distance between the support block 15 and the pre-limiting component, and the length of this distance is the area where the copper wires of the subsequent connecting harness 5 are located.

[0058] When the connecting harness 5 is limited by the pre-limiting assembly, the pre-limiting assembly is pushed toward the inside of the installation cavity 201. At this time, one end of the pushing spring 22 is subjected to the pushing pressure, and the other end can only be compressed due to the obstruction of the support block 15 and the connecting assembly, thereby making the distance between the support block 15 and the pre-limiting assembly instantly smaller, so that the previously extra copper wire can be inserted into the deformable copper ring 16.

[0059] As a preferred embodiment of the present invention, the pre-limiting component includes a turntable 7, a fixed ring 13, a flip block 19 and two pressure rings 23. An anti-slip cavity 704 is provided on the side of the turntable 7 close to the mother hole 202, and a plurality of sliding openings 706 are provided on the side of the fixed ring 13 close to the mother hole 202. A plurality of wiring openings 701 are provided through the side wall of the turntable 7, and an installation opening 131 is provided through one side of the fixed ring 13. A pressure cavity 705 is provided in the middle of the side wall of the turntable 7. One end of the flip block 19 is hinged to one end of the installation opening 131 through a hinge. The two pressure rings 23 are fixedly connected to the inner walls of the flip block 19 and the fixed ring 13 respectively. The outer walls of the two pressure rings 23 are slidably connected to the inner wall of the pressure cavity 705, pushing the spring The end of 22 away from the mother hole 202 is against the side wall of the turntable 7, the anti-slip plate 21 is located in the anti-slip cavity 704, and the outer wall of the anti-slip plate 21 is slidably connected to the inner wall of the anti-slip cavity 704, a plurality of connecting rods 14 are respectively located in a plurality of sliding openings 706, and the outer wall of the connecting rod 14 is slidably connected to the inner wall of the sliding opening 706, the end of the fixing ring 13 away from the mother hole 202 is connected to both the sealing assembly and the plurality of supporting assemblies, the outer wall of the connecting wire harness 5 is slidably connected to the inner wall of the wiring opening 701, and the outer wall of the connecting wire harness 5 is also slidably connected to the outer walls of the two pressure rings 23, the outer wall of the turntable 7 is slidably connected to the inner wall of the installation cavity 201, and a buckle groove 191 is provided on the upper surface of the flip block 19 away from the hinge end.

[0060] More specifically, when the connecting harness 5 is not installed, the turntable 7 will have a certain distance from the support block 15 due to the action of the push spring 22, and this distance does not exceed the maximum sliding length of the anti-slip plate 21 in the anti-slip cavity 704.

[0061] Because the turntable 7 is connected to the fixed ring 13 through the pressure ring 23 and the pressure chamber 705, the fixed ring 13 cannot fall off the turntable 7. And because the anti-drop plate 21, the sliding column 20 and the anti-drop chamber 704 are all circular, and the connecting rod 14 and the sliding opening 706 are both rectangular, the fixed ring 13 and the turntable 7 can be in a rotational connection relationship. Also because of the above-mentioned connection relationship, the fixed ring 13 and the support block 15 are in a relationship where they can slide close to each other, and the turntable 7 and the support block 15 are also in a relationship where they can rotate, so it will not affect the rotation of the connecting harness 5 inserted into the wiring opening 701.

[0062] Specifically, when installing, it is only necessary to manually buckle the buckle slot 191, unfold the flip block 19 to one side through the hinge, then expose the installation port 131 and the first wiring port 701, and then put the first connecting wire harness 5 into the first wiring port 701, and then rotate the turntable 7. The rotation of the turntable 7 will rotate with the connecting wire harness 5, and because of the action of the pressure ring 23 between the turntable 7 and the fixing ring 13, the connecting wire harness 5 will be squeezed in the wiring port 701, and it is not easy to fall off.

[0063] Then, follow the same operation to install all the remaining connecting harnesses 5 in the wiring openings 701, finally buckle the flip block 19, and press the last connecting harness 5 together through the pressing ring 23 on the flip block 19, and then push the installed connecting harnesses 5, turntable 7 and fixing ring 13 into the installation cavity 201 together.

[0064] As a preferred solution of the present invention, the sealing assembly includes a plurality of elastic blocks 6, the fixing ring 13 is away, and a pressure hole 132 is opened on the outer wall of one end of the mother hole 202. One ends of the plurality of elastic blocks 6 are hinged to the inner wall of the pressure hole 132, and the other ends of the plurality of elastic blocks 6 are against the outer wall of the turntable 7. The connecting wiring harness 5 is located between the elastic block 6 and the wiring opening 701, and sealing strips are provided at the connection between the elastic block 6, the wiring opening 701 and the connecting wiring harness 5. The outer walls of the plurality of elastic blocks 6 are slidably connected to the inner wall of the installation cavity 201.

[0065] More specifically, when the connecting harness 5 is not installed, the plurality of elastic blocks 6 are in a tilted state (as can be seen here). Fig.10 ), so it does not affect the normal placement of the connecting harness 5 and the rotation of the following turntable 7.

[0066] When the connection harness 5 is installed, at this time, several connection harnesses 5, turntable 7 and fixing ring 13 are pushed into the installation cavity 201 together, and the back sides (slanted surfaces) of several elastic blocks 6 are against the opening of the installation cavity 201, and can then be buckled down. After several connection harnesses 5, turntable 7 and fixing ring 13 are pushed into the installation cavity 201 together and completely enter the installation cavity 201, the elastic block 6 will also be completely attached to the surface of the turntable 7, and in conjunction with the sealing strip, the gap between the connection harness 5 and the wiring opening 701 can be blocked to prevent dust in the external environment (if the sealing strip has a better sealing effect, it can even be moisture-proof) from entering the installation cavity 201.

[0067] As a preferred solution of the present invention, the supporting assembly includes an anti-slipping top block 8 and an extrusion spring 12, and a plurality of receiving openings 203 are provided on the inner wall of the installation cavity 201 away from the mother hole 202. One end of the anti-slipping top block 8 is hinged to one end of the receiving opening 203, and the other end of the anti-slipping top block 8 is abutted against the end of the elastic block 6 away from the pressure opening 132. The upper surface of the anti-slipping top block 8 close to the end of the elastic block 6 is fixedly connected to the lower end of the extrusion spring 12, and the upper end of the extrusion spring 12 is fixedly connected to the inner wall of the receiving opening 203, and the depth of the receiving opening 203 is not less than the total length of the anti-slipping top block 8 and the compressed extrusion spring 12.

[0068] More specifically, when several connecting wire harnesses 5, turntable 7 and fixing ring 13 are pushed into the installation cavity 201 together, the fixing ring 13 will squeeze the anti-detachment top block 8 and the extrusion spring 12 into the storage port 203 together, so it will not affect the normal movement of several connecting wire harnesses 5, turntable 7 and fixing ring 13.

[0069] When the connecting harnesses 5, the turntable 7 and the fixing ring 13 squeeze through the anti-slip top block 8, the extrusion spring 12 lacks pressure, and the anti-slip top block 8 can be lifted up at one end close to the elastic block 6, and supported from the outward end of the elastic block 6, thereby reducing the possibility of loosening and falling off.

[0070] As a preferred solution of the present invention, the outer wall of the turntable 7 away from the female hole 202 is provided with a turn indicator arrow 702 and an indicator number 703, and the turn indicator arrow 702 and the indicator number 703 match the plurality of wiring openings 701.

[0071] More specifically, by setting the turn indicator arrow 702 and the indicator number 703, the installer can more quickly understand the corresponding position and rotation direction, thereby reducing the probability of failure caused by different wiring harness directions inside the male connector 1 and the female connector 2 or other reasons.

[0072] As a preferred solution of the present invention, a plurality of slide grooves 204 are formed on the inner wall of the installation cavity 201 , a plurality of sliders 18 are fixedly connected to the side wall of the support block 15 , and the outer walls of the sliders 18 are slidably connected to the inner walls of the plurality of slide grooves 204 .

[0073] More specifically, by setting the slide groove 204 and the slider 18, firstly, the moving trajectory of the support block 15 can be limited so that the support block 15 can only move in a specific direction; secondly, it can prevent the support block 15 from rotating in the installation cavity 201, causing misalignment between the connecting component and the mother hole 202; finally, the sliding distance of the support block 15 can be limited to prevent the support block 15 from slipping out of the installation cavity 201.

[0074] As a preferred solution of the present invention, a plurality of slope extrusion blocks 11 are fixedly connected to the inner wall of the installation cavity 201 close to the mother hole 202, the ends of the slope extrusion blocks 11 close to the mother hole 202 are thicker, and the ends away from the mother hole 202 are thinner, and the outer walls of the plurality of slope extrusion blocks 11 are respectively abutted against the outer walls of the ends of the plurality of deformable copper rings 16 away from the placement port 151.

[0075] More specifically, by providing the sloped extrusion block 11, when the copper wire of the connecting wiring harness 5 is inserted into the deformable copper ring 16, the sloped extrusion block 11 can press the deformable copper ring 16 downward, so that the connection between the deformable copper ring 16 and the connecting wiring harness 5 is more stable, and this part of the extrusion limit can also be used to prevent the connecting wiring harness 5 from loosening or even falling off from the deformable copper ring 16.

[0076] As a preferred solution of the present invention, a post 9 is fixedly connected to the middle of the installation cavity 201 near one end of the mother hole 202, and the other end of the post 9 is abutted against the side of the support block 15 near the mother hole 202, and the length of the post 9 is the same as the length of the mother hole 202 and the connecting copper ring 10.

[0077] More specifically, by setting the positioning column 9, it is possible to avoid the situation where the momentary impact force when the support block 15 is forced to move toward the inside of the installation cavity 201 causes the mother hole 202, the connecting copper ring 10, the copper column 17 or the deformable copper ring 16 to deform.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
