[0051] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0052] 1 to 6 , according to an embodiment of the present invention, the wiring harness connector includes a housing 10, a mounting block 20, and a connecting mechanism 30. A cavity 13 is provided inside the housing 10, and the housing 10 includes a first shell 11. Two through holes 111 are provided at the bottom end of the first shell 11. The through holes 111 are used for inserting male pins at the board end. The mounting block 20 is provided in the cavity 13 inside the housing 10. The mounting block 20 includes a first mounting portion 21. The first mounting portion 21 is installed in the first shell 11. The first mounting portion 21 is provided with two mounting cavities 211. The two mounting cavities 211 are spaced apart along the length direction of the first mounting portion 21. The two mounting cavities 211 correspond one to one with the two through holes 111. The connecting mechanism 30 is provided on the mounting block 20. The connecting mechanism 30 includes two connecting cavities. The connector 31 and the two connecting components 32 correspond one to one with the two mounting cavities 211, the two connectors 31 and the two connecting components 32 respectively. The connector 31 includes a first connecting portion 311 and a second connecting portion 312. The first connecting portion 311 is connected to the second connecting portion 312. The two first connecting portions 311 are horizontally arranged below the mounting cavity 211 and are arranged opposite to each other. The two connecting components 32 are respectively connected to the two first connecting portions 311 and are respectively accommodated in the two mounting cavities 211. The two second connecting portions 312 are connected to the ends of several cables 1, and the male pins at the board ends are inserted into the connecting components 32 through the through holes 111.

[0053] Specifically, the connecting mechanism 30 is mounted on the mounting block 20, which is in turn mounted in the cavity 13 of the housing 10. The connecting mechanism 30 is used to connect the board-end male pin and the cable 1, thereby achieving electrical connection. More specifically, the board-end male pin is inserted into the mounting cavity 211 in the first mounting portion 21 through the through hole 111 at the lower end of the first housing 11. The mounting cavity 211 is also provided with a connecting assembly 32 of the connecting mechanism 30. The board-end male pin is connected to the connecting assembly 32 after contact with the connecting assembly 32. At the same time, the connecting assembly 32 is connected to the first connecting portion 311 of the connector 31 of the connecting mechanism 30. In addition, the first connecting portion 311 and the second connecting portion 312 are connected to each other, so the board-end male pin can be indirectly connected to the second connecting portion 312 through the connecting assembly 32 and the first connecting portion 311. Since several cables 1 are connected to the second connecting portion 312, the board-end male pin is ultimately electrically connected to the cable 1.

[0054] It should be noted that the first connecting part 311 and the second connecting part 312 of the connector 31 can be an integrally formed copper busbar or separately arranged copper busbars connected by contact, so no specific limitation is made in this embodiment, and it is sufficient that the connection between the connecting component 32 and the cable 1 can be achieved.

[0055] It should also be noted that the length direction of the first mounting portion 21 mentioned in this embodiment is the front-to-back direction as shown in the figure, so the mounting cavity 211, the first connecting portion 311, and the connecting assembly 32 in this embodiment are all distributed along the front-to-back direction of the first mounting portion 21. It can be imagined that the left-right direction of the first mounting portion 21 shown in this embodiment is the width direction of the first mounting portion 21. In addition, the first connecting portion 311 is horizontally arranged below the mounting cavity 211, while the plane where the second connecting portion 312 is located is perpendicular to the plane where the first connecting portion 311 is located. In this case, the second connecting portion 312 is vertically arranged. It can also be seen that the up-down direction of the first mounting portion 21 shown in this embodiment is the height direction of the first mounting portion 21.

[0056] Therefore, it can be understood that the two mounting cavities 211 on the first mounting portion 21 of this embodiment are spaced apart along the length of the first mounting portion 21. At this time, the two connecting components 32 and the first connecting portions 311 of the two connecting members 31 are all spaced apart along the length of the first mounting portion 21. The arrangement along the length of the first mounting portion 21 can significantly reduce the width of the connector, thereby streamlining the overall volume of the connector and making it easier for users to install the connector in narrow spaces. It should also be noted that the second connecting portion 312 is perpendicular to the first connecting portion 311. While the first connecting portion 311 is horizontally arranged, the second connecting portion 312 is vertically arranged, which can significantly reduce the width of the wiring harness connector and further streamline the overall width and volume of the wiring harness connector. In addition, the second connecting portion 312 of the connecting member 31 is connected to a plurality of cables 1. The board-end male pins inserted into the connecting component 32 through the through hole 111 are electrically connected to the first connecting portion 311, thereby indirectly connecting to the vertically arranged second connecting portion 312, and ultimately achieving high-power circuit transmission with the plurality of cables 1. It can be understood that the vertically arranged second connecting portion 312 can connect more cables 1, so that the wiring harness connection can meet the requirements of high-power power transmission.

[0057] 2 and 4 , further, in some embodiments of the present invention, the mounting block 20 further includes a second mounting portion 22, which is disposed on the upper side of one end of the first mounting portion 21 along the length direction of the first mounting portion 21. That is, as shown in the figure, the second mounting portion 22 is mounted on the upper side of the rear end of the first mounting portion 21. The second mounting portion 22 is provided with two receiving grooves 221, which are disposed opposite to each other along the width direction of the second mounting portion 22. The two second connecting portions 312 are respectively vertically disposed in the receiving grooves 221. Therefore, it can be understood that the first connecting portion 311 is mounted below the mounting cavity 211 of the first mounting portion 21, while the second connecting portion 312 is mounted in the receiving groove 221 of the second mounting portion 22. The cable 1 is disposed in the receiving groove 221 of the second mounting portion 22 and can be connected to the second connecting portion 312, thereby being connected to the first connecting portion 311 through the second connecting portion 312. At this time, the distribution direction of the two connecting components 32 is parallel to the length direction of the cable 1, which can greatly reduce the width of the wiring harness connector, thereby streamlining the overall volume of the wiring harness connector and making it easier for users to install the connector in a narrow space.

[0058] It is important to emphasize that each connector 31 ultrasonically welds multiple cables 1, effectively reducing the resistance of the cables 1. The simultaneous electrical conduction of multiple cables 1 effectively increases the connector's transmission power. Furthermore, the multiple cables 1 are spaced vertically apart, minimizing the width of the wiring harness connector. The arrangement of the cables 1 is parallel to the height of the wiring harness connector, allowing the cables 1 to pass through the narrow cavity without bending or twisting, thus avoiding bending and torsional stress in the wiring harness and effectively improving the connector's operational stability and safety.

[0059] Referring to Figures 2, 4, and 7 to 12, further, in some other embodiments of the present invention, the direction of the receiving groove 221 in the second mounting portion 22 of the wiring harness connector can extend along the length direction of the second mounting portion 22 or along the vertical direction of the second mounting portion 22. That is, the direction of the receiving groove 221 can extend along the front-to-back direction or the up-down direction as shown in the figure. When the receiving groove 221 extends along the front-to-back direction, that is, the direction of the receiving groove 221 extends along the front-to-back direction of the second mounting portion 22, and the second connecting portion 312 of the connector 31 is also vertically arranged in the receiving groove 221, at this time, the direction of the cable 1 connected to the second connecting portion 312 can be consistent with the direction of the receiving groove 221: front-to-back direction, so the width dimension of the wiring harness connector can be greatly reduced, thereby streamlining the overall volume of the wiring harness connector, making it convenient for users to install the wiring harness connector in a narrow and low space. When the receiving groove 221 extends in the up-down direction, that is, the direction of the receiving groove 221 extends along the vertical direction of the second mounting portion 22, and the second connecting portion 312 of the connector 31 is also vertically arranged in the receiving groove 221, the direction of the cable 1 connected to the second connecting portion 312 can be consistent with the direction of the receiving groove 221: vertical direction. Without increasing the width of the wiring harness connector, the positional relationship between the cable 1 and the wiring harness connector is changed, and the horizontal output can be converted to a vertical output, which is convenient for users to install the wiring harness connector in a narrow space. The direction of the receiving groove 221 can extend along the length direction of the second mounting portion 22 or along the vertical direction of the second mounting portion 22 to meet different usage scenarios.

[0060] Referring to Figures 1, 3, 6, 7, 9, and 12, further, in some embodiments of the present invention and another embodiment of the cable connector 1, when the mounting block 20 includes a second mounting portion 22, the housing 10 provided in the embodiment of the present invention may also include a second shell 12. The second shell 12 is disposed on the upper side of one end of the first shell 11 along the length of the first shell 11. Specifically, as shown in the figure, the second shell 12 is mounted on the upper side of the rear end of the first shell 11, corresponding to the position of the second mounting portion 22. Therefore, the second mounting portion 22 is disposed in the second shell 12. Specifically, openings 121 are provided at the upper and lower ends and the rear end of the second shell 12. The cable 1 passes through the openings 121 and connects to the second connecting portion 312. It should be noted that, as can be seen from the above embodiments, the receiving slot 221 of the second mounting portion 22 can extend in the front-to-back direction or the vertical direction. Therefore, the provision of openings 121 at the upper and lower ends and the rear end of the second shell 12 facilitates the connection of the cable 1 through the openings 121 to the second connecting portion 312 in the receiving slot 221 regardless of the extending direction of the receiving slot 221. It should also be noted that an opening 121 should also be opened at the rear end of the first shell 11 to facilitate the installation of the mounting block 20 into the cavity 13 of the housing 10 through the opening 121 at the rear ends of the first shell 11 and the second shell 12 .

[0061] 3, 4, 6, 8, and 12, in some embodiments and another embodiment of the present invention, the second mounting portion 22 is provided with a partition 222, the partition 222 being located between the two receiving grooves 221, and the two second connecting portions 312 being disposed on opposite sides of the partition 222. An accommodating gap 223 is formed between the second connecting portions 312 and the partition 222, and the end portion of the cable 1 is accommodated in the accommodating gap 223 and connected to the second connecting portion 312. By providing the partition 222 and the accommodating gap 223 between the partition 222 and the second connecting portion 312, the end structure of the cable 1 can be accommodated and hidden, and in conjunction with the second housing 12 outside the second connecting portion 312, the cable 1 is protected, effectively extending the service life of the wiring harness connector.

[0062] 2 , 6 , 8 , and 12 , in some embodiments and another embodiment of the present invention, the lower portion of the first mounting portion 21 defines two horizontally disposed slots 212. The two slots 212 are spaced apart along the length of the first mounting portion 21 and correspond one-to-one with the two first connecting portions 311. The two first connecting portions 311 engage with the two slots 212, respectively. Specifically, the first connecting portions 311 of the two connectors 31 engage with the two slots 212, one in front of the other, and are located below the mounting cavity 211. The connecting assembly 32 of the connecting mechanism 30 is mounted in the mounting cavity 211, with a portion of the connecting assembly 32 located in the slots 212. Therefore, the connecting assembly 32 can be inserted into the first connecting portion 311, while the first connecting portion 311 can be sleeved onto the outside of the connecting assembly 32, thereby achieving connection between the connecting assembly 32 and the first connecting portion 311.

[0063] Referring to Figures 2, 6, 8, and 12, further, in some embodiments and another embodiment of the present invention, the slots 212 are disposed on opposite sides of the first mounting portion 21 along the width direction of the first mounting portion 21, and the two first connecting portions 311 are located on opposite sides of the first mounting portion 21 along the width direction. That is, the slots 212 are respectively provided on the left and right sides of the first mounting portion 21 and extend horizontally in the left-right direction. Therefore, the two first connecting portions 311 can be disposed opposite each other, one in front of the other, on the left and right sides of the first mounting portion 21. This allows the two connecting members 31 to be spaced apart on either side of the first mounting portion 21. The distance between the spaced connecting members 31 reduces inductance between them, thereby facilitating power transmission. Furthermore, the provision of the slots 212 allows the connecting member 31 to be secured by engaging the first connecting portions 311 before the housing 10 is installed, thereby facilitating assembly of the wiring harness connector and effectively improving the installation stability of the connecting member 31 and the structural tightness of the wiring harness connector.

[0064] It can be understood that a sinking platform that sinks inward can be provided on one side of the first mounting portion 21 in the left and right directions to accommodate the corresponding first connecting portion 311, thereby further reducing the width dimension of the first mounting portion 21, and further reducing the width dimension of the entire wiring harness connector, effectively improving the installation stability of the connector 31 and the structural tightness of the wiring harness connector.

[0065] 2, 4 to 6, 8, and 10 to 12, in some embodiments and another embodiment of the present invention, the connection assembly 32 includes: a sleeve 321 and a contact 322. The sleeve 321 is inserted into the first connection portion 311, and the first connection portion 311 is sleeved on the outside of the sleeve 321 and abuts against the outer wall of the sleeve 321; the contact 322 is disposed in the sleeve 321, and the contact 322 is provided with a socket 3221, which is coaxial with the sleeve 321. The male pin on the board end can be inserted into the socket 3221 in the contact 322 and connected to the contact 322. So it can be imagined that the board-end male pin is inserted into the socket 3221 in the contact piece 322, and the board-end male pin is in contact and connected with the contact piece 322, and the contact piece 322 is passed through the sleeve 321. At the same time, the first connecting part 311 is sleeved on the outside of the sleeve 321 and abuts against the outer wall of the sleeve 321, so the board-end male pin is indirectly connected to the first connecting part 311 through the contact piece 322 and the sleeve 321.

[0066] It should be noted that the contact piece 322 can be an integrally formed metal cylindrical drum spring, the wall of which is composed of a number of bars connected at both ends, and the bars are evenly distributed and elastic. The bars as a whole can be spiral or parallel to the axis. At the same time, the projection of the axial section of the wall of the drum spring is a hyperbola or an axisymmetric wavy line. The bottom position of the hyperbola of the bar or the trough position of the wavy line can abut against the outer wall of the board end male pin inserted into the socket 3221, and the elastic bar will automatically hold the board end male pin to achieve circuit conduction. The contact piece 322 can be integrally formed, with a simple structure and stable connection, which can effectively improve the convenience of using the wiring harness connector.

[0067] 2, 4 to 6, 8, and 10 to 12, further, in some embodiments and another embodiment of the present invention, the connection assembly 32 further includes an end cap 323 and a snap ring 324. The end cap 323 is sleeved on the top of the sleeve 321; the snap ring 324 is disposed at the top of the end cap 323 and the sleeve 321, and the inner diameter of the snap ring 324 is smaller than the inner diameter of the insertion hole 3221.

[0068] It is understood that the connection assembly 32 further includes a hollow end cap 323 and a snap ring 324. The end cap 323 is sleeved on the top of the sleeve 321 and abuts against the inner wall of the installation cavity 211. The snap ring 324 is located between the end cap 323 and the sleeve 321. The inner diameter of the snap ring 324 is smaller than the inner diameter of the socket 3221. By providing the end cap 323, the installation stability of the connection assembly 32 can be further improved. The snap ring 324 is provided between the end cap 323 and the sleeve 321. After the board-end male pin is inserted into the socket 3221 and is tightly held by the contact member 322, the end of the board-end male pin passes through the snap ring 324 and the hollow hole of the end cap 323. At this time, the snap ring 324 can cooperate with the annular groove provided on the end of the board-end male pin, thereby achieving the effect of locking the board-end male pin, which can further ensure that the board-end male pin is prevented from vibrating and falling off from the connection assembly 32, thereby further improving the operational stability of the wiring harness connector.

[0069] Referring to Figures 2, 4 to 6, 8, and 10 to 12, further, in some embodiments of the present invention and another embodiment, two accommodating cavities 112 are provided at the upper end of the first shell 11. The two accommodating cavities 112 are located above the installation cavity 211 and are connected to the installation cavity 211. The accommodating cavities 112 correspond one-to-one with the installation cavity 211. When the length of the board end male pin is long, the end of the board end male pin may pass through the end cover 323 and abut against the inner side wall of the shell 10, thereby causing the board end male pin to be unable to be fully inserted into the connecting component 32 of the wiring harness connector. By providing the accommodating cavity 112, the accommodating cavity 112 can accommodate the part of the end of the board end male pin that passes through the end cover 323, thereby achieving an avoidance effect, ensuring that the board end male pin can be stably inserted into the jack 3221, and effectively improving the structural rationality of the wiring harness connector.

[0072] Specifically, with reference to FIG13 , in some other embodiments of the present invention, the handle portion 40 includes a lifting rod, which is arranged in a relief (not shown) at the top of the first mounting portion 21 or in a relief portion at the top of the first shell 11. When the lifting rod is arranged at the top of the first mounting portion 21, a relief hole 41 is provided at a corresponding position on the top of the first shell 11. The relief hole 41 is used to avoid the lifting member, and the lifting member is connected to the lifting rod. It should be noted that the relief portion at the top of the first mounting portion 21 and the relief portion at the top of the first shell 11 are portions for accommodating the lifting rod. The two ends of the lifting rod are respectively connected to the first mounting portion 21 or the first shell 11, and the corresponding relief portion is a recessed portion on the first mounting portion 21 or the first shell 11. The lifting rod is located in the recessed portion, but there is a gap between it and the first shell 11 or the first mounting portion 21. At this time, a flexible handle (not shown) can be passed through the gap between the lifting rod and the first shell 11 or the first mounting portion 21, and then wrapped around the lifting rod. The wiring harness connector can be lifted upward by the handle to remove it from the board end.

[0073] It should also be noted that when the lifting rod is set on the top of the first mounting block 20, an avoidance hole 41 should be provided at the corresponding position on the first shell 11 to facilitate the handle to pass through the first shell 11 and wrap around the lifting rod on the first mounting part 21.

[0074] The handle in the above embodiment can be a flexible rope or braided belt, or a cable 1, etc. In this embodiment, the handle is not specifically limited, and can pass through the avoidance portion and be wrapped around the lifting rod to lift the wiring harness connector.

[0075] Furthermore, in some embodiments of the present invention, the housing 10 further includes a handle loop 14, the ends of which are connected to the first housing 11, and a handle portion 40 is provided on the handle loop 14. Of course, referring to Figures 1, 5, 7, 11, and 13, the ends of the handle loop 14 can also be connected to the first housing 11 and the second housing 12, respectively, to form a handle portion, making it easier for the user to remove the wiring harness connector through the handle loop 14.

[0076] It should be noted that the handle loop 14 and the housing 10 can also be integrally formed. A handle portion 40 can be provided on the handle loop 14. In this case, the handle portion 40 can be a handle rod or a threaded sleeve, allowing the wiring harness connector to be lifted by the handle member or screw. Of course, the handle member can also be directly wrapped around the handle loop 14.

[0077] In summary, the present invention does not impose any specific restrictions on the structure of the handle portion 40 , as long as it can facilitate the removal of the wiring harness connector in a narrow space.

[0078] 3 to 5, 9 to 11, and 13, in some embodiments of the present invention, a first latch 113 is provided at the bottom of the first housing 11. The first latch 113 is provided on one side of the through hole 111 along the length direction of the first housing 11. A first buckle 213 is provided on the outer side of the bottom of the first mounting portion 21. The first buckle 213 corresponds to the position of the first latch 113 and can be snapped into the first latch 113. By providing the first buckle 213 and the first latch 113, after the first housing 11 completely covers the mounting block 20 and the connector 31, the first buckle 213 automatically enters the first latch 113, thereby limiting the position of the first housing 11 along the length direction of the mounting block 20, preventing the mounting block 20 from peeling off during use of the wiring harness connector, effectively improving the connection stability between the first housing 11 and the mounting block 20, and improving the structural stability of the wiring harness connector.

[0079] 1 , 3 , 6 , 7 , 9 , 12 , and 13 , further, in some embodiments of the present invention, the first housing 11 is further provided with a second snap 114, which is disposed on one side of the first housing 11 along the width direction of the first shell 10. A second bayonet 214 is further disposed on the outer side of the first mounting portion 21, which is disposed on one side of the first mounting portion 21 along the width direction of the first mounting portion 21. The second snap 114 and the second bayonet 214 are disposed at positions corresponding to each other, and the second snap 114 can be snapped into the second bayonet 214. The second bayonet 214 provided on one side of the first mounting portion 21 is a groove, and the second snap 114 is disposed on the corresponding side of the first housing 11. A boss is disposed on the inner side of the second snap 114, and the boss can be snapped into the groove. By providing the second buckle 114, which is located on the left and right sides of the mounting block 20, the main body of the mounting block 20 is fixed for a second time, further improving the connection stability between the housing 10 and the mounting block 20 and improving the user's feel.

[0080] 1 , 2 , 6 to 8 , and 12 , further, in some embodiments of the present invention, the housing 10 further includes a second housing 12, on which third bayonet holes 122 are provided. The third bayonet holes 122 are arranged on both sides of the second housing 12 along the width direction of the second housing 12. Third clips 224 are provided on the outer side of the second mounting portion 22. The third clips 224 are arranged on both sides of the second mounting portion 22 along the width direction of the second mounting portion 22. The positions of the third bayonet holes 122 and the third clips 224 correspond one-to-one, and the third clips 224 can be snapped into the third bayonet holes 122. By snapping the third clips 224 into the third bayonet holes 122, the position of the second mounting block 20 can be determined, and the main body of the mounting block 20 can be fixed three times, further improving the connection stability between the housing 10 and the mounting block 20. When the handle 40 is used to lift the wiring harness connector, looseness, shaking, and other problems between the second mounting block 20 and the second housing 12 can be avoided, making it easier to pull out and remove the entire wiring harness connector.

[0081] Referring to Figure 14 , in some embodiments of the present invention, two or more cables 1 are provided. The cables 1 on the two second connecting portions 312 are arranged in parallel, and the cables 1 on the two second connecting portions 312 are intertwined. The two connecting members 31 are connected to the positive and negative poles, respectively, that is, to the two second connecting portions 312. The cables 1 on the second connecting portions 312 are arranged in parallel. As can be seen from the above embodiment, the cable 1 can extend in both the vertical and horizontal directions of the wiring harness connector. When the cables 1 extend horizontally, multiple cables 1 are arranged vertically, and the positive and negative cables 1 on the same horizontal plane are intertwined, thereby reducing inductance and, in turn, minimizing the impact of inductance on power transmission. Similarly, when the cables 1 extend vertically, multiple cables 1 are arranged horizontally, and the positive and negative cables 1 on the same vertical plane are intertwined, similarly achieving the goal of reducing inductance.

[0082] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
