Description

Technical Field

[0001] This utility model relates to the field of wire harness design technology, and in particular to a flip-type wire harness. Background Technology

[0002] A wire harness is a flexible medium for transmitting electrical signals. Its characteristic is that it can integrate multiple wires used to transmit electrical signals into a bundle, and then fix them with metal terminals and connectors to form a plug-in structure for docking devices.

[0003] In traditional wire harnesses, metal terminals are mounted on the connector in an array. Typically, spring tabs extending outwards and tilting to both sides are provided at the front end of the metal terminals, forming a barbed structure. During wire harness assembly, the metal terminals are inserted axially into the connector from the rear. During insertion, the spring tabs are compressed and retracted until they pass a step at a predetermined depth. At this point, the spring tabs open outwards to form a barbed structure and abut against the step, thus preventing them from retracting. The drawback of this traditional design is:

[0004] Firstly, when the wire is pulled backward, if the pulling force is too great, it is easy to damage the spring structure of the metal terminal, causing the metal terminal to be scrapped.

[0005] Secondly, after the wire harness is assembled, an electrical test is required. If the metal terminal is found to be inserted incorrectly, it needs to be removed from the connector and then reinserted into the correct position. This requires a specialized disassembly tool with a pointed tip that can be inserted into the connector from the front. The tip can be used to press the spring tab inward, forcing it to retract, allowing the metal terminal to be pulled out of the connector. This operation is difficult and inefficient. Utility Model Content

[0006] Based on this, the present invention provides a flip-type wire harness, which designs the connector as an openable flip-type structure, improves the installation method of the metal terminals from through-hole to placement, and uses the limiting groove set on the connector to achieve axial positioning of the metal terminals. It abandons the traditional spring sheet structure, improves the stability and tensile strength of the metal terminal positioning, and can easily complete the disassembly of the metal terminals by unlocking the buckle structure and flipping the cover, without the need for auxiliary tools, with low operation difficulty and high disassembly efficiency.

[0007] A flip-type wire harness, comprising:

[0008] A connector; the connector includes: a body and a cover hinged to the body; the body has a plurality of semi-open first terminal slots arranged in an array; each first terminal slot has a stop portion and a backstop portion arranged along the axial direction, and a limiting groove is formed between the stop portion and the backstop portion along the axial direction; the cover has a plurality of second terminal slots; the second terminal slots are semi-open and are arranged in pairs with the first terminal slots; one side of the cover is hinged to one side of the body, and the other side of the cover has a snap-fit ​​portion for fastening the other side of the body;

[0009] Metal terminals are inserted into the connector; multiple metal terminals are arranged one-to-one between a first terminal slot and a second terminal slot; each metal terminal has a rigid wing extending radially outward; the wing is housed in a limiting slot and is arranged parallel to the first terminal slot, with the front end of the wing abutting a stop portion and the rear end of the wing abutting a backstop portion; and

[0010] Wires connecting metal terminals; there are multiple wires, each corresponding to a metal terminal.

[0011] The aforementioned flip-top type wire harness features a flip-top connector design. When installing the metal terminals, the operator can flip the cover open to place the metal terminals directly into the first or second terminal slot from top to bottom. Then, the cover is flipped closed and snapped in place, aligning the first and second terminal slots. At this point, the metal terminal's flaps are confined between the stop and anti-reverse parts of the main body, preventing the metal terminal from moving forward or backward. This design, with its openable flip-top structure, improves the installation method of the metal terminals from through-feeding to placement. The limiting groove on the connector provides axial positioning of the metal terminals, eliminating the need for traditional spring clips and improving the stability and tensile strength of the metal terminal positioning. Furthermore, the metal terminals can be easily disassembled by unlocking the snap-on structure and flipping the cover, without the need for auxiliary tools, resulting in low operation difficulty and high disassembly efficiency.

[0012] In one embodiment, the bottom of the first terminal slot is marked with a number or letter. These markings allow operators to quickly locate the correct terminal slot for the current metal terminal, preventing mistake-proofing and improving assembly accuracy.

[0013] In one embodiment, the metal terminal has a locking block extending radially outward, the locking block being perpendicular to the first terminal slot; the first terminal slot has a first locking groove for engaging the locking block. During assembly, the metal terminal can be initially positioned on the first terminal slot before the cover is closed.

[0014] In one embodiment, the second terminal slot is provided with a second slot for engaging the locking block. During assembly, the metal terminal can be initially positioned on the second terminal slot before the cover is closed.

[0015] In one embodiment, the tail of the metal terminal is provided with a first riveting portion and a second riveting portion arranged sequentially along the axial direction; the first riveting portion rivets the conductor of the wire, and the second riveting portion rivets the outer sheath of the wire. By using two riveting portions to rivet different areas of the metal terminal and the wire, the stability of the riveting is improved.

[0016] In one embodiment, a U-shaped first hinge seat is provided on one side of the main body, and a U-shaped second hinge seat is provided on one side of the cover. The first and second hinge seats are connected in series by a pivot. The hinge between the main body and the cover is achieved by using a pivot connection, which results in a strong structural stability and simple assembly.

[0017] In one embodiment, the flip-type wiring harness further includes a collar for connecting the connector; the collar is axially sleeved on the outer periphery of the body and the cover. The collar allows for secondary locking of the cover, improving the stability of the cover closure. Attached Figure Description

[0040] like Figures 1 to 11 As shown, it is a flip-type wire harness 100 according to one embodiment of the present utility model.

[0041] like Figure 1 and Figure 2 As shown, the flip-type wiring harness 100 includes: a connector 10, metal terminals 20 passing through the connector 10, and wires 30 connecting the metal terminals 20. The connector 10 is used to house the metal terminals 20 and to connect devices. The metal terminals 20 and the wires 30 are connected to form a channel for electrical signal transmission.

[0042] The following text, combined with Figures 1 to 11 The above-mentioned flip-type wiring harness 100 will be further explained.

[0043] Combination Figures 2 to 6 As shown, the connector 10 includes a body 11 and a cover 12 hinged to the body 11. A receiving cavity for accommodating a metal terminal 20 is formed between the body 11 and the cover 12, and the receiving cavity is divided into a plurality of terminal slots.

[0044] Combination Figures 6 to 8 As shown, in this embodiment, a U-shaped first hinge seat 111 is provided on one side of the main body 11, and a U-shaped second hinge seat 121 is provided on one side of the cover 12. The first hinge seat 111 and the second hinge seat 121 are connected in series by a pivot 13. The hinge between the main body 11 and the cover 12 is achieved by using a pivot connection, which results in a strong structural stability and simple assembly.

[0045] like Figure 7 and Figure 8 As shown, the main body 11 is provided with a plurality of semi-open first terminal slots 112 arranged in an array. Each first terminal slot 112 is provided with a stop portion 1121 and a backstop portion 1122 distributed along the axial direction, and a limiting groove is formed between the stop portion 1121 and the backstop portion 1122 along the axial direction.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, the bottom of the first terminal slot 112 is provided with a number or letter marking. The number or letter marking allows operators to quickly locate the correct terminal slot for the current metal terminal 20, preventing mistake-proofing and improving assembly accuracy.

[0047] like Figure 9 and Figure 10 As shown, the cover 12 is provided with multiple second terminal slots 122. Combined with... Figure 3 and Figure 4 As shown, the second terminal slot 122 has a semi-open structure and is arranged in pairs with the first terminal slot 112. One side of the cover 12 is hinged to one side of the main body 11, and the other side of the cover 12 is provided with a snap-fit ​​part 123 for fastening the other side of the main body 11.

[0048] For example, in this embodiment, the main body 11 is provided with four first terminal slots 112, and is designed in a 2*2 distribution pattern. Correspondingly, in this embodiment, there are two covers 12, which are distributed vertically, and each cover 12 is provided with two second terminal slots 122.

[0049] It should be noted that, based on the flip-top structure design of this solution, the first terminal slot 112 is only applicable to N*1 or N*2 layouts, that is, corresponding to the design of a single cover 12 or two covers 12 respectively.

[0050] like Figure 3 and Figure 4 As shown, there are multiple metal terminals 20, each corresponding to the first terminal slot 112 and the second terminal slot 122. Figure 11 As shown, the metal terminal 20 has a rigid wing 21 extending radially outward. The wing 21 is received in a limiting groove and is arranged parallel to the first terminal groove 112. The front end of the wing 21 abuts against the stop portion 1121, and the rear end of the wing 21 abuts against the anti-reverse portion 1122. (Combined with 4 and...) Figure 11 As shown, when the metal terminal 20 is pulled backward, the anti-reverse part 1122 abuts against the rear end of the wing 21. The structure of the wing 21 is set to be rigid and parallel to the first terminal groove 112. Therefore, during the process of the metal terminal 20 being pulled backward, the wing 21 can also maintain good structural fixation, and finally achieve the function of stopping the metal terminal 20 from moving backward and preventing it from falling off.

[0051] like Figure 4 and Figure 11 As shown, in this embodiment, the metal terminal 20 is provided with a locking block 24 extending radially outward, and the locking block 24 is disposed perpendicular to the first terminal slot 112. The first terminal slot 112 is provided with a first locking groove 113 for engaging the locking block 24. During assembly, the metal terminal 20 can be initially positioned on the first terminal slot 112 before the cover 12 is closed.

[0052] To allow for more flexible assembly of the metal terminal 20, it can be placed on the cover 12 first, and then the metal terminal 20 can be fixed by flipping and closing the cover 12. For example, as Figure 4 and Figure 10 As shown, in this embodiment, the second terminal slot 122 is provided with a second slot 124 for engaging the locking block 24. During assembly, the metal terminal 20 can be initially positioned on the second terminal slot 122 before the cover 12 is closed.

[0053] like Figure 4 As shown, there are multiple wires 30, each connected to a corresponding metal terminal 20. For example... Figure 4 and Figure 11As shown, in this embodiment, the tail of the metal terminal 20 is provided with a first riveting portion 22 and a second riveting portion 23 arranged sequentially along the axial direction. The first riveting portion 22 rivets the conductor of the wire 30, and the second riveting portion 23 rivets the outer sheath of the wire 30. By using two riveting portions to rivet different areas of the metal terminal 20 and the wire 30, the stability of the riveting is improved.

[0054] Brief description of working principle:

[0055] like Figure 4 and Figure 6 As shown, connector 10 has a flip-top design. When installing the metal terminal 20, the operator can place the metal terminal 20 directly onto the first terminal slot 112 or the second terminal slot 122 from top to bottom by flipping open the cover 12. Then, the cover 12 is flipped closed and locked in place, so that the first terminal slot 112 and the second terminal slot 122 are connected. At this time, the flap 21 of the metal terminal 20 is restricted between the stop part 1121 and the anti-reverse part 1122 of the main body 11, so that the metal terminal 20 cannot move forward or backward.

[0056] In other embodiments, to further reinforce the cover 12 and prevent it from being easily opened by external force, the flip-top wiring harness 100 may further include a collar for connecting the connector 10. The collar is axially sleeved on the outer periphery of the body 11 and the cover 12. The collar can be used to lock the cover 12 a second time, improving the stability of the cover 12 when closed.

[0057] The aforementioned flip-type wire harness 100 designs the connector 10 as an openable flip-type structure, improves the installation method of the metal terminal 20 from through-feeding to placement, and uses the limiting groove provided on the connector 10 to achieve axial positioning of the metal terminal 20, abandoning the traditional spring sheet structure, improving the stability and tensile strength of the metal terminal 20 positioning, and the metal terminal 20 can be easily disassembled by unlocking the buckle structure and flipping the cover 12 without the need for auxiliary tools, making the operation simple and the disassembly efficiency high.

[0058] 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.

[0059] 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.
