[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0048] This invention discloses a wire harness end-connection device, which includes: a first upper connection interface 1, a first lower connection interface 2, a second upper connection interface 3, a second lower connection interface 4, and a connection mechanism 5.
[0049] For example, such as Figure 1 As shown, the docking device designed in this invention has docking interfaces on both sides, including a first upper docking interface 1, a first lower docking interface 2, a second upper docking interface 3, and a second lower docking interface 4. The wire harness is inserted into the docking interface, and a connecting mechanism is located in the middle. The length of the connecting mechanism can be arbitrarily set, and two wire harnesses located at arbitrary locations can be docked through the docking device 5. The docking interfaces on both sides can be symmetrically arranged.
[0050] Specifically, the first lower interface 2 has a plurality of first lower grooves at its first end; the first upper interface 1 has a first cavity at its first end; the second end of the first upper interface 1 is axially connected to the second end of the first lower interface 2 to form a first interface; the first cavity includes a first upper shell 11, a first elastic element 12, a first conductor 13, a first puncture element 14, and a first partition element 15; the first upper shell 11 has a plurality of first partition elements 15 inside, which divide the first cavity into a plurality of first small cavities; the plurality of first small cavities can cooperate with the plurality of first lower grooves to form a plurality of first wire grooves.
[0051] For example, the first lower interface 2 has a plurality of first lower grooves at its first end; the first upper interface 1 has a first cavity at its first end; and the second end of the first upper interface 1 is axially connected to the second end of the first lower interface 2 to form a first pair of interfaces. Figure 1 The image shows the effect when the first upper interface 1 and the first lower interface 2 are joined together. Figure 2The image shows the effect when the first upper interface 1 and the first lower interface 2 are opened. The first cavity includes a first upper shell 11, a first elastic element 12, a first conductor 13, a first piercing element 14, and a first partition 15; the first upper shell 11 is provided with a plurality of first partitions 15, which divide the first cavity into a plurality of first smaller cavities; the plurality of first smaller cavities can cooperate with a plurality of first lower slots to form a plurality of first wire slots. Figure 3 The image shows the cross-sectional effect when the first upper interface 1 and the first lower interface 2 are joined together. Figure 3 There are three first wire slots. The number of first wire slots can be set according to actual needs, such as two first wire slots. When the wire harness needs to be connected, open the first upper pair interface 1 and the first lower pair interface 2, place the wire harness into the first pair interface, and then close the first upper pair interface 1 and the first lower pair interface 2, that is, place the wire harness into the first wire slot.
[0052] Specifically, the plurality of first small cavities are respectively provided with a first elastic element 12, a first conductor 13, and a first puncture element 14 from the inside to the outside; the inner wall of the first upper outer shell 11 is fixedly connected to one end of the first elastic element 12, the other end of the first elastic element 12 is fixedly connected to one end of the first conductor 13, and a plurality of first puncture elements 14 are installed on the other end of the first conductor 13.
[0053] For example, the docking device designed in this invention has a lower part for placing the wire harness and an upper part for connecting the wire harness. The first upper docking interface 1 is divided into several small cavities by a first partition 15, and from the inside out, a first elastic element 12, a first conductive element 13, and a first piercing element 14 are respectively arranged. Preferably, the first elastic element 12, the first conductive element 13, and the first piercing element 14 are all parallel to the upper surface of the inner wall of the first upper outer shell 11, so that the wire harness is placed directly below the first elastic element 12, the first conductive element 13, and the first piercing element 14. The inner wall of the first upper outer shell 11 is fixedly connected to one end of the first elastic element 12, and the other end of the first elastic element 12 is fixedly connected to one end of the first conductive element 13. Several first piercing elements 14 are installed on the other end of the first conductive element 13.
[0054] Specifically, the second upper interface 3 has a second cavity at its first end; the second lower interface 4 has a plurality of second lower grooves at its first end; the second end of the second upper interface 3 and the second end of the second lower interface 4 are axially connected to form a second interface; the second cavity includes a second upper shell, a second elastic material, a second conductor, a second piercing body, and a second partition body; the second upper shell has a plurality of second partition bodies inside, which divide the second cavity into a plurality of second smaller cavities; the plurality of second smaller cavities can cooperate with the plurality of second lower grooves to form a plurality of second wire grooves; the plurality of second smaller cavities are formed by the inner... The outer surface is provided with a second elastic element, a second conductor, and a second piercing element; the inner wall of the second upper outer shell is fixedly connected to one end of the second elastic element, the other end of the second elastic element is fixedly connected to one end of the second conductor, and a plurality of second piercing elements are installed on the other end of the second conductor; the second end of the first upper interface 1 and the second end of the first lower interface 2 are fixedly connected to the first end of the connecting mechanism 5; the second end of the second upper interface 3 and the second end of the second lower interface 4 are fixedly connected to the second end of the connecting mechanism 5; the first conductor 13 is electrically connected to the second conductor through the connecting mechanism 5.
[0055] For example, the design of the second upper interface 3 and the second lower interface 4 is similar to that of the first upper interface 1 and the first lower interface 2. Those skilled in the art can derive the design of the second upper interface 3 and the second lower interface 4 from the design of the first upper interface 1 and the first lower interface 2. The first conductor 13 is electrically connected to the second conductor through the connecting mechanism 5. The connecting mechanism 5 can have various designs, such as a wire.
[0056] Specifically, the first piercing body 14 comprises multiple blades; the blades of the first piercing body 14 are positioned away from the first conductor 13; the blades of the first piercing body 14 are parallel to the length direction of the first small cavity. Alternatively, the first piercing body 14 may comprise multiple needle-like objects; the needle tips of the first piercing body 14 are positioned away from the first conductor 13. The hardness of the first piercing body 14 is greater than the hardness of the wire harness outer sheath but less than the hardness of the wire harness metal core. The first conductor 13 is made of metal and can be bent under pressure. The first partition 15 is made of an insulating material.
[0057] For example, when the wire harness is placed onto the first lower connector 2 and the first upper connector 1 is closed, the first piercing body 14, due to its hardness being greater than the hardness of the wire harness outer sheath but less than or equal to the hardness of the wire harness metal core, can pierce the wire harness outer sheath but cannot pierce the wire harness metal core. Preferably, the first piercing body 14 is made of soft copper, which has good conductivity and meets the required hardness. After piercing, the first piercing body 14 comes into contact with the metal core inside the wire harness. When current flows between the first piercing body 14 and the wire harness, there is resistance at the contact point between the first piercing body 14 and the metal core inside the wire harness. The magnitude of the resistance is affected by the contact area between the first piercing body 14 and the metal core inside the wire harness; the larger the contact area, the smaller the resistance. To reduce the resistance, multiple first piercing bodies 14 are provided. The first piercing body 14 can be multiple blades; the blades of the first piercing body 14 are positioned away from the first conductive body 13; the blades of the first piercing body 14 are parallel to the length direction of the first small cavity. The first piercing element 14 can be multiple needle-like objects; the needle tips of the first piercing elements 14 are positioned away from the first conductor 13. When multiple first piercing elements 14 pierce the same wire harness, the contact area increases, the resistance decreases, and power loss is reduced. This also avoids overheating at the connection point due to excessive resistance between the first piercing element 14 and the metal core within the wire harness. Since the cross-section of the metal core within the wire harness is circular, the penetration depth of the first piercing elements 14 varies depending on their position. For example, the penetration depth is shallower near the center of the metal core and deeper near the sides. The first conductor 13 is made of metal and can be bent under pressure. A first elastic element 12 is provided between the first conductor 13 and the first upper outer shell 11, and the first elastic element 12 has a certain degree of elasticity. When the first piercing elements 14 pierce the wire harness, the reaction force of the first piercing elements 14 on the first conductor 13 varies depending on their position. Figure 4 As shown, this causes the first conductor 13 to bend and the center of the first elastic element 12 to be concave. At this time, the sequential connection of the multiple first puncture bodies 14 near the center forms an arc shape. The first puncture body 14 close to the metal core inside the wire harness plays a conductive role. Current flows from the metal core of the wire harness to the first puncture body 14, then to the first conductor 13, and through the connecting mechanism to the second conductor. When the wire harness sheath is damaged, different wire harnesses need to be insulated from each other. The first partition body 15 is made of an insulating material. Preferably, the height of the first partition body 15 is greater than the height of the first puncture body 14, so that the damaged parts of different wire harnesses are isolated by the first partition body 15.
[0058] Specifically, the second piercing body is a blade; the blade edge of the second piercing body is positioned away from the second conductor; the blade edge of the second piercing body is parallel to the length direction of the second small cavity. Alternatively, the second piercing body can be a needle-like object; the needle tip of the second piercing body is positioned away from the second conductor. The hardness of the second piercing body is greater than the hardness of the wire harness outer sheath but less than the hardness of the wire harness metal core. The second conductor is made of metal and can be bent under pressure. The second partition is made of an insulating material.
[0059] For example, the design of the second upper interface 3 is similar to that of the first upper interface 1. Those skilled in the art can derive the design of the second upper interface 3 from the design of the first upper interface 1, and thus can also derive the design of the second piercing body, the second conductive body, and the second partition body. The first piercing body 14 and the second piercing body can both be multiple blades, or both be multiple needles, or one can be multiple blades and the other can be multiple needles.
[0060] When using the docking device designed in this invention to assemble the wiring harness, the following method is used:
[0061] Disconnect the power supply to the wire harness and determine its specific type, such as a combination of multiple three-core and two-core cables. A three-core cable includes three inner cores. Remove the outer sheath of the first three-core cable; the outer sheath of the inner cores does not need to be removed. Place each inner core into a different first lower slot of the first lower connector 2, and so on, until all the inner cores in the wire harness are placed into different first lower slots of the first lower connector 2. If the wire harness includes too many inner cores, multiple connection devices can be used. After placement, close the first upper connector. If necessary, wrap the first upper connector 1 and the first lower connector 2 with insulating tape. Connect another wire harness to the second connector in the same way. This completes the wire harness connection. During connection, ensure that the wire harnesses of the first and second connectors correspond one-to-one; that is, the two wire harnesses to be connected must be placed in the same lower slots of the first and second connectors.
[0062] The connecting mechanism 5 can also be equipped with devices such as LED lights. When both ends are powered on, the LED lights will light up, indicating that the connection is successful.
[0063] The docking device designed in this invention can realize the docking of various wire harnesses. The docking operation is convenient and does not require professional electricians. It is also easy to produce in industry.
[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
