Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and in particular to a quick-release wire harness structure. Background Technology

[0002] A wire harness is an electronic connector that mounts multiple metal terminals and wires onto a connector. Its key feature is its ability to transmit multiple different electrical signals, making it particularly common in industrial control buses and control buses for new energy vehicles. Taking an industrial control bus as an example, multiple wire harnesses can extend from it, and each wire harness can also extend into multiple wire harnesses. Therefore, the complexity of a wire harness is related to the number and routing of channels on the industrial control bus. The complex and ever-changing product requirements mean that wire arrangement and metal terminal connection still require manual labor in the current wire harness production process.

[0003] Traditional wire harness structures include: a connector, metal terminals passing through the connector, and wires connecting the metal terminals. During assembly, the tail of the metal terminal is first crimped to the wire (commonly riveted), and then the metal terminal is inserted axially forward from the rear end of the connector into the connector's terminal slot. To ensure the metal terminal is secured after insertion (preventing it from being pulled out when the wire is pulled back), a common practice is to have outward-opening spring tabs on both sides of the metal terminal. These spring tabs form a barbed structure to engage with the stepped portion on the inner wall of the connector's terminal slot (the two spring tabs form a figure-eight-like structure). While this design offers very high assembly efficiency, disassembly is extremely difficult. It requires the use of an auxiliary tool with two pointed tips, inserted axially backward from the front end of the connector's terminal slot. The pointed tips compress the two spring tabs, causing them to retract simultaneously. In this retracted state, the wire is quickly grasped and pulled back, thus pulling the metal terminal out along with it. Utility Model Content

[0004] Based on this, the present invention provides a quick-release wire harness structure, which has a socket on the metal terminal, and locks the metal terminal by inserting a plug through the socket, and then limits the plug by a limiting plate. When it is necessary to remove the metal terminal, the limiting plate and the plug can be removed in sequence, and the metal terminal can be pulled out without the need for auxiliary tools, making disassembly easy.

[0005] A quick-release wire harness structure, comprising:

[0006] Connector; The connector has multiple terminal slots arranged in an array; The bottom of the connector has a limiting slot that extends radially through the terminal slots; The inner wall of the terminal slots is also provided with a stop block;

[0007] Metal terminals are inserted into the connector; the metal terminals are inserted into the terminal slots; the metal terminals have sockets; the sockets are collinear with the limiting slots; the metal terminals also have stop plates and riveting parts arranged sequentially behind the sockets; the stop plates abut against the rear end of the stop blocks;

[0008] Wires connecting metal terminals; there are multiple wires, and each wire is connected in a one-to-one correspondence; one end of each wire is riveted to a riveted part;

[0009] An insert inserted between the connector and the metal terminal; the insert is inserted upwards from the bottom of the connector into the limiting slot and passes through the socket; and

[0010] A limiting plate for connecting the connector; the limiting plate is slidably connected to the bottom of the connector in a direction parallel to the bottom of the connector, and the limiting plate abuts against the plug and covers the plug.

[0011] The quick-release wiring harness structure described above involves first riveting the metal terminals to the wires during assembly. Then, the metal terminals are axially inserted into the connector's terminal slots until the stop plate of the metal terminal abuts against the stop block of the connector. Next, the plug-in is inserted from the bottom of the connector to lock the position of the metal terminals. Finally, the limiting plate is slidably installed at the bottom of the connector to limit the plug-in's position, completing the wiring harness assembly. When it is necessary to remove the metal terminals from the connector, the limiting plate is slid out, the plug-in is pulled out, and the metal terminals can then be pulled out by pulling the wires. This operation is simple and convenient, requiring no auxiliary tools. Through this design, a socket is provided on the metal terminal, and the metal terminal is locked by the plug-in passing through the socket, further limited by the limiting plate. When it is necessary to disassemble the metal terminals, simply remove the limiting plate and the plug-in in sequence to pull out the metal terminals, eliminating the need for auxiliary tools and simplifying disassembly.

[0012] In one embodiment, the top of the connector has a hook that extends forward along the axial direction. When the connector mates with the interface of an electronic device, it can hook onto the interface of the electronic device to improve the stability of the connection between the connector and the interface of the electronic device.

[0013] In one embodiment, the plug-in includes: a base plate and a plurality of parallel vertical rods connected to the base plate; the shape of the base plate is adapted to the opening shape of the limiting slot; the vertical rods pass through the limiting slot and through the insertion hole. Positioning is achieved by the base plate aligning with the opening of the limiting slot, and the metal terminal is locked by the vertical rods. This design is simple and highly reliable.

[0014] In one embodiment, the base plate has notches at both ends. The notches allow operators to insert their fingers into the notches to pry out the inserts, reducing the difficulty of operation.

[0015] In one embodiment, a stop is provided on one side of the limiting plate; the stop abuts against one side of the connector. When the limiting plate is slidably installed, the stop can limit the insertion depth of the limiting plate, thereby improving the assembly accuracy.

[0016] In one embodiment, the stop portion has a first engaging portion at each end; the connector has a second engaging portion on one side that engages with the first engaging portions. The engagement between the stop portion and the connector improves the installation stability of the limiting plate. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0048] like Figures 1 to 18 As shown, it is a quick-release wire harness structure 100 of one embodiment of the present utility model.

[0049] like Figures 1 to 4 As shown, the quick-release wiring harness structure 100 includes: a connector 10, a metal terminal 20 passing through the connector 10, a wire 30 connecting the metal terminal 20, a plug 40 passing between the connector 10 and the metal terminal 20, and a limiting plate 50 connecting the connector 10. The connector 10 is used to house the metal terminal 20 and for interface connection with electronic equipment. The metal terminal 20 and the wire 30 are connected to form an electrical signal transmission channel. The plug 40 is used to lock the metal terminal 20 onto the connector 10. The limiting plate 50 is used to restrict the position of the plug 40 to prevent the plug 40 from dislodging from the connector 10.

[0050] The following text, combined with Figures 1 to 18 The quick-release harness structure 100 described above will be further explained.

[0051] like Figures 5 to 7 As shown, the connector 10 has a plurality of terminal slots 11 arranged in an array. For example, in this embodiment, there are four terminal slots 11 arranged in a 2*2 array. The bottom of the connector 10 has a limiting slot 12 that extends radially from bottom to top through the terminal slot 11, and the terminal slot 11 is also provided with a stop block 13.

[0052] like Figure 5 As shown, in this embodiment, the top of the connector 10 is provided with a hook 14 extending forward along the axial direction. When the connector 10 is connected to the interface of the electronic device, it can be hooked to the interface of the electronic device through the hook 14 to improve the connection stability between the connector 10 and the interface of the electronic device.

[0053] like Figure 3 As shown, in this embodiment, there are four metal terminals 20, each corresponding to the other, inserted into the terminal slot 11. Combined with... Figure 8 As shown, each metal terminal 20 has a socket 21, and the socket 21 is collinear with the limiting slot 12. The metal terminal 20 also has a stop piece 22 and a riveting part 23 sequentially arranged behind the socket 21. Figure 3 As shown, the stop piece 22 abuts against the rear end of the stop block 13, thereby limiting the maximum insertion depth of the metal terminal 20 in the terminal slot 11.

[0054] like Figures 2 to 4 As shown, in this embodiment, there are four wires 30, which are connected one-to-one, and one end of each wire 30 is riveted to the riveting part 23.

[0055] Combination Figure 3 , Figure 11 ,as well as Figure 12 As shown, the plug 40 is inserted upwards from the bottom of the connector 10 into the limiting slot 12 and passes through the socket 21. Figures 9 to 12 As shown, in this embodiment, the plug-in 40 includes a base plate 41 and a plurality of parallel vertical rods 42 connected to the base plate 41. Since in this embodiment, the number of metal terminals 20 is four and distributed in a 2x2 pattern, the number of vertical rods 42 is two. Figure 12 As shown, the shape of the base plate 41 matches the opening shape of the limiting slot 12. Combined Figure 3 and Figure 11 As shown, the vertical rod 42 passes through the limiting slot 12 and the insertion hole 21. The base plate 41 is positioned by docking with the opening of the limiting slot 12, and the metal terminal 20 is locked by the vertical rod 42. The structure is simple and highly reliable.

[0056] Furthermore, combined Figure 9 and Figure 12 As shown, in this embodiment, the base plate 41 has notches 411 at both ends. The notches 411 allow operators to insert their fingers into the notches 411 to pry out the plug-in 40, reducing the difficulty of operation.

[0057] like Figures 1 to 3 As shown, the limiting plate 50 is slidably connected to the bottom of the connector 10 in a direction parallel to the bottom of the connector 10, and the limiting plate 50 abuts against the plug 40 and covers the plug 40 (see [reference]). Figure 3 The top surface of the limiting plate 50 abuts against the top of the plug-in 40.

[0058] like Figure 13 and Figure 14 As shown, in this embodiment, a stop portion 51 is provided on one side of the limiting plate 50. The stop portion 51 abuts against one side of the connector 10. When the limiting plate 50 is slidably installed, the stop portion 51 can limit the insertion depth of the limiting plate 50, thereby improving the assembly accuracy.

[0059] Furthermore, such as Figure 18As shown, the stop portion 51 has a first engaging portion 511 at each end. The connector 10 has a second engaging portion 15 on one side that engages with the first engaging portion 511. By engaging the stop portion 51 with the connector 10, the installation stability of the limiting plate 50 is improved.

[0060] Brief description of working principle:

[0061] like Figure 15 As shown, during assembly, the metal terminal 20 is first riveted to the wire 30. Then, the metal terminal 20 is inserted axially forward into the terminal slot 11 of the connector 10 until the stop piece 22 of the metal terminal 20 abuts against the stop block 13 of the connector 10.

[0062] like Figure 16 As shown, next, insert the plug 40 from the bottom of the connector 10 to lock the position of the metal terminal 20. Finally, slide the limiting plate 50 on the bottom of the connector 10 to limit the plug 40. At this time, the plug 40 is covered and hidden by the limiting plate 50, and the wire harness assembly is completed.

[0063] When it is necessary to remove the metal terminal 20 from the connector 10, slide the limiting plate 50 out from the bottom side of the connector 10, and then pull the plug 40 out downwards. The metal terminal 20 is unlocked. Then, the metal terminal 20 can be pulled out by pulling the wire 30 backwards. The operation is simple and convenient and does not require auxiliary tools.

[0064] The aforementioned quick-release wiring harness structure 100 features a socket 21 on the metal terminal 20. The metal terminal 20 is locked by a plug 40 passing through the socket 21, and the plug 40 is further limited by a limiting plate 50. When it is necessary to remove the metal terminal 20, simply remove the limiting plate 50 and the plug 40 in sequence to pull out the metal terminal 20; no auxiliary tools are required, making disassembly easy.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
