Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness design technology, and in particular to an anti-detachment wire harness. Background Technology
[0002] A wire harness is a medium for signal transmission between two electronic components. A wire harness includes: wires, terminals connected to the ends of the wires, and connectors for the terminals to pass through. The wire harness manufacturing process mainly includes: cutting the wires to a predetermined length, then stripping the insulation from both ends of the wires. Next, crimping the tail of the terminal to the end of the wire. Finally, inserting the terminal into the connector from the tail of the connector.
[0003] Traditional wire harnesses have the following drawbacks: terminals typically have barbed spring clips. When the terminal is inserted into the connector, the end of the spring clip engages with the inner wall of the connector to prevent detachment. The disadvantage of this traditional design is that when the wire is subjected to external force, the barbed spring clips of the terminal can easily be bent excessively and damaged, making the terminal easy to pull out, resulting in weak anti-detachment performance. Utility Model Content
[0004] Based on this, the present invention provides an anti-detachment wire harness, which uses the connector and the anti-reverse plug to clamp and fix the terminal, so that the terminal cannot move forward or backward. Moreover, the anti-reverse plug is radially inserted in the connector, which can provide a stable locking force for the terminal, thereby improving the anti-detachment capability of the terminal.
[0005] A type of anti-detachment wire harness, comprising:
[0006] wire;
[0007] Terminal for connecting wires; the tail of the terminal is riveted to the end of the wire; a stop plate is provided at the front end of the terminal;
[0008] A connector for connecting terminals; the connector has a movable channel for inserting terminals axially into the connector; the inner wall of the movable channel has a first stepped portion for abutting the front end of a stop plate; the connector also has lateral slots arranged crosswise with the movable channel; the lateral slots extend radially through both sides of the connector; and
[0009] A locking insert for connecting the connector; the locking insert is inserted radially into the lateral slot from one side of the connector, and the locking insert abuts against the rear end of the stop plate.
[0010] In the aforementioned anti-dislodgement wire harness, during assembly, after the tail of the terminal is riveted to the end of the wire, the terminal is inserted axially into the movable channel of the connector until the front end of the terminal's stop plate abuts against the first step portion within the movable channel. At this point, the terminal cannot advance further. Next, the anti-reverse insert is inserted into the lateral slot of the connector, abutting against the rear end of the terminal's stop plate. At this point, the terminal cannot retract. Finally, the terminal's stop plate is clamped between the first step portion and the anti-reverse insert and thus fixed, locking the terminal axially within the connector and preventing it from advancing or retracting. Through this design, the connector and the anti-reverse insert clamp and fix the terminal, preventing it from advancing or retracting. Furthermore, the anti-reverse insert, which passes radially through the connector, provides a stable locking force to the terminal, thereby improving the terminal's anti-dislodgement capability.
[0011] In one embodiment, the tail of the terminal is provided with a first collar and a second collar that are spaced apart sequentially along the axial direction of the terminal; both the first collar and the second collar are riveted to the conductor of the wire. Using multiple collars achieves multi-segment riveting between the terminal and the conductor of the wire, improving the stability of the connection between the terminal and the wire.
[0012] In one embodiment, the front end of the terminal is further provided with a barbed spring; the inner wall of the movable channel is provided with a second step portion for abutting the rear end of the spring. When the terminal is inserted into the movable channel, the rear end of the spring abuts against the second step portion, which not only allows for initial positioning of the terminal before insertion of the anti-reverse plug, but also improves the terminal's anti-disengagement capability.
[0013] In one embodiment, one end of the anti-reverse plug has a limiting plate that abuts against one side of the connector; the other end of the anti-reverse plug has a plug that extends to the other side of the connector. The limiting plate is used to control the maximum insertion depth of the anti-reverse plug in the lateral slot.
[0014] In one embodiment, the plug snaps into the connector. When the anti-reverse plug is inserted into the lateral slot, it is secured to the connector by snapping, preventing the anti-reverse plug from coming loose.
[0015] In one embodiment, the anti-detachment harness further includes: a locking member connecting the anti-reverse plug; the locking member abuts against the side of the connector opposite to the limiting plate; the locking member is plate-shaped and has a insert; the end of the plug extends to the outside of the connector and has a socket for the insert to pass through. When the anti-reverse plug is inserted into the lateral slot, the insert of the locking member is inserted into the socket of the plug, thereby clamping the connector between the limiting plate and the locking member, preventing the anti-reverse plug from loosening.
[0016] In one embodiment, the connector has a limiting hole on its outer side for inserting the front end of the insert. The limiting hole serves to limit the insertion of the insert, reducing the risk of the insert being deformed or damaged by impact.
[0017] In one embodiment, the connector has an anti-disengagement clip at the top or bottom. When using the harness, the anti-disengagement clip can be used to fasten the connector to the target device, thus preventing the connector from detaching. Attached Figure Description

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0044] like Figures 1 to 13 As shown, it is an embodiment of the anti-detachment wire harness 100 of this utility model.
[0045] like Figures 1 to 5 As shown, the anti-detachment wire harness 100 includes: a wire 10, a terminal 20 connecting the wire 10, a connector 30 connecting the terminal 20, and a backstop plug 40 connecting the connector 30. The wire 10 and the terminal 20 are connected to form a channel for electrical signal transmission. The connector 30 is used for inserting the terminal 20 to carry the terminal 20 and also serves to protect the terminal 20. The backstop plug 40 cooperates with the connector 30 to clamp and fix the terminal 20 in the connector 30.
[0046] The following text, combined with Figures 1 to 13 Further explanation is provided regarding the aforementioned anti-detachment wire harness 100.
[0047] like Figure 1As shown, in this embodiment, there are four wires 10, which are distributed in a square array. It should be noted that when designing a wire harness, the number of wires 10 is determined according to the number of channels of electrical signals that the wire harness needs to transmit, and is not limited to the four shown in this embodiment.
[0048] like Figure 6 and Figure 7 As shown, the tail of terminal 20 is riveted to the end of wire 10, and a stop piece 23 is provided at the front end of terminal 20.
[0049] Here, in order to improve the connection stability between terminal 20 and wire 10, such as Figure 6 and Figure 7 As shown, in this embodiment, the tail of the terminal 20 is provided with a first collar 21 and a second collar 22 that are sequentially spaced along the axial direction of the terminal 20. Both the first collar 21 and the second collar 22 are riveted to the conductor of the wire 10. By using multiple collars, a multi-segment riveting connection is achieved between the terminal 20 and the conductor of the wire 10, improving the stability of the connection between the terminal 20 and the wire 10.
[0050] Furthermore, in this embodiment, the diameter of the first ring 21 is smaller than the diameter of the second ring 22. In other embodiments, the diameter of the first ring 21 may also be equal to the diameter of the second ring 22.
[0051] like Figures 8 to 10 As shown, connector 30 has a movable channel 31 for inserting terminal 20 along the axial direction of connector 30. (Connection) Figure 3 and Figure 10 As shown, the inner wall of the movable channel 31 is provided with a first step 311 for abutting the front end of the stop plate 23. Figure 10 As shown, the connector 30 is also provided with a lateral slot 32 that is cross-shaped with the active channel 31, and the lateral slot 32 passes through both sides of the connector 30 radially.
[0052] Combination Figure 4 and Figure 8 As shown, the anti-reverse plug 40 is inserted into the lateral slot 32 radially from one side of the connector 30, and the anti-reverse plug 40 abuts against the rear end of the stop piece 23.
[0053] like Figure 2 and Figure 11 As shown, in this embodiment, one end of the anti-reverse plug 40 is provided with a limiting plate 41 that abuts against one side of the connector 30. The other end of the anti-reverse plug 40 is provided with a plug 42 that extends to the other side of the connector 30. The limiting plate 41 is used to control the maximum insertion depth of the anti-reverse plug 40 in the lateral slot 32.
[0054] Furthermore, in order to prevent the anti-reverse plug-in 40 from easily coming loose, there are various implementation methods.
[0055] For example, in some embodiments, the plug 42 snaps into the connector 30. When the anti-reverse plug 40 is inserted into the lateral slot 32, it is secured to the connector 30 by snapping, preventing the anti-reverse plug 40 from coming loose. For example, a first latching portion is provided at the end of the plug 42, and a second latching portion is provided on the side of the connector 30 to engage with the first latching portion.
[0056] For example, such as Figure 1 As shown, in this embodiment, the anti-detachment harness 100 may further include a locking member 50 connecting to the anti-reverse plug 40. The locking member 50 abuts against the side of the connector 30 opposite to the limiting plate 41. Figure 12 As shown, the locking member 50 is plate-shaped and has a insert 51. The end of the plug 42 extends to the outside of the connector 30 and has a socket 421 through which the insert 51 passes. When the anti-reverse plug 40 is inserted into the lateral slot 32, the insert 51 of the locking member 50 is inserted into the socket 421 of the plug 42, thereby clamping the connector 30 between the limiting plate 41 and the locking member 50 to prevent the anti-reverse plug 40 from loosening.
[0057] Furthermore, such as Figure 1 and Figure 9 As shown, in this embodiment, the connector 30 has a limiting hole 33 on its outer side for inserting the front end of the insert 51. The limiting hole 33 is used to limit the insertion of the insert 51, reducing the risk of the insert 51 being deformed or damaged by impact.
[0058] Brief description of working principle:
[0059] like Figure 3 and Figure 5 As shown, during assembly, after the tail of terminal 20 is riveted to the end of wire 10, terminal 20 is inserted axially into the movable channel 31 of connector 30 until the front end of stop piece 23 of terminal 20 abuts against the first step portion 311 in the movable channel 31. At this point, terminal 20 cannot proceed further (see [reference]). Figure 13 Next, the anti-reverse insert 40 is inserted into the lateral slot 32 of the connector 30. The anti-reverse insert 40 abuts against the rear end of the stop piece 23 of the terminal 20, at which point the terminal 20 cannot retract. Finally, the stop piece 23 of the terminal 20 is clamped between the first step portion 311 and the anti-reverse insert 40 and is fixed, and the terminal 20 is axially locked in the connector 30 and cannot move forward or backward (see See). Figure 1 and Figure 3 ).
[0060] Based on the above working principle, in order to further enhance the anti-detachment capability of terminal 20, such as Figure 6As shown, in this embodiment, the front end of the terminal 20 is also provided with a barbed spring piece 24. The inner wall of the movable channel 31 is provided with a second step portion (not shown) for abutting the rear end of the spring piece 24. When the terminal 20 is inserted into the movable channel 31, the rear end of the spring piece 24 abuts against the second step portion, which not only allows for initial positioning of the terminal 20 between insertion and anti-retraction plugs 40, but also improves the anti-disengagement capability of the terminal 20.
[0061] In addition, such as Figure 8 and Figure 9 As shown, in this embodiment, the connector 30 is provided with an anti-disengagement buckle 35 at its top or bottom. When using this wire harness, the connector 30 can be fastened to the target device by the anti-disengagement buckle 35, thus preventing the connector 30 from disengaging.
[0062] The aforementioned anti-detachment wire harness 100 uses the connector 30 and the anti-reverse plug 40 to clamp and fix the terminal 20, making it impossible for the terminal 20 to move forward or backward. Moreover, the anti-reverse plug 40 is radially inserted into the connector 30, which can provide a stable locking force for the terminal 20, thereby improving the anti-detachment capability of the terminal 20.
[0063] 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.
[0064] 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.
