[0030] To make the objectives, technical solutions, and advantages of this embodiment clearer, the technical solutions of this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, not all embodiments. Based on the embodiments in this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0032] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The terminal interface provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] For ease of understanding and explanation, the terms "first direction," "second direction," and "third direction" appearing in this application are first defined and explained. In the embodiments of this application, "first direction" refers to the length direction of the base plate 1. "Second direction" refers to the width direction of the base plate 1 (or the insertion direction of the wire harness 4 relative to the terminal interface). "Third direction" refers to the height direction of the base plate 1. The third direction is substantially perpendicular to the plane containing the first and second directions.

[0035] like Figures 1 to 9 As shown, this application discloses an anti-detachment terminal interface, which can be integrally stamped using a metal material (such as copper, aluminum, or stainless steel). Specifically, the terminal interface may include a base plate 1 and a cover plate 2. The cover plate 2 is rotatably constructed or formed at both ends of the base plate 1 opposite to each other in a first direction. A first bend 3 is integrally formed between the base plate 1 and the cover plate 2. At least two first bends 3 are respectively formed at both ends of the base plate 1 opposite to each other in the first direction. The first bends 3 are configured to be rotatable, thereby allowing the cover plates 2 at both ends of the base plate 1 to rotate above the base plate 1 via the first bends 3, and to be stacked with the base plate 1 in a spaced-apart state in a third direction (or the height direction of the base plate 1).

[0036] Furthermore, when the cover plates 2 at both ends of the base plate 1 are rotated through the rotatable first bend 3 and positioned at intervals above the base plate 1, a wire-pressing space is formed between the base plate 1 and the cover plates 2. This wire-pressing space can be used to accommodate part or all of one or more wire bundles 4 to be pressed and fixed, which are inserted into the wire-pressing space along the second direction.

[0037] In some alternative embodiments, the first bending portion 3 may comprise a plurality of independent first bending units. In other words, each first bending unit may be individually driven. The plurality of independent first bending units may be arranged at intervals from each other along the second direction of the base plate 1. Preferably, the plurality of independent first bending units may be configured to be different from each other. For example, each first bending unit has a different length from each other.

[0038] likeFigures 1 to 5 As shown, the first bending portion 3 arranged at both ends of the base plate 1 may include a first flat plate 33 and a first arc-shaped plate 32 formed on both sides of the first flat plate 33. The two first arc-shaped plates 32 are integrally connected to the base plate 1 and the cover plate 2 on the same side, respectively. Both the first flat plate 33 and the first arc-shaped plate 32 extend along the second direction of the base plate 1. Specifically, when the cover plates 2 at both ends of the base plate 1 are rotated to the top surface of the base plate 1 by means of the first bending portion 3, the first flat plate 33 and the first arc-shaped plate 32 form a bending groove 31. This bending groove 31 can partially wrap the wire harness 4 placed in the wire pressing space along the first direction (or the two transverse ends of the base plate 1).

[0039] See Figure 1 The cover plate 2 has a through hole 21 on its surface. In some alternative embodiments, the through hole 21 can be constructed as a circle, rectangle, triangle, trapezoid, regular / irregular polygon, or other possible arbitrary geometric shape. The accompanying drawings and descriptions of the embodiments in this application are merely preferred examples for non-limiting illustration and are not intended to limit the specific structure of this application.

[0040] It is understood that the number of through holes 21 on the surface of the cover plate 2 can be one or more. Furthermore, the multiple through holes 21 on the surface of each cover plate 2 can be formed at different locations. Optionally, two cover plates 2 facing each other can contain different numbers of through holes 21. Alternatively, the multiple through holes 21 on two cover plates 2 facing each other can be arranged in different ways.

[0041] See Figures 1 to 4 The through hole 21 has a pressing part 22 for pressing against the wire harness 4. Specifically, when the cover plate 2 is rotated through the rotatable first bend 3 and placed above the base plate 1 at intervals, and one or more wire harnesses 4 are inserted into the wire pressing space between the cover plate 2 and the base plate 1 along the second direction, the pressing part 22 contacts and presses against the surface of the wire harness 4 approximately along the third direction (or approximately in the direction perpendicular to the base plate 1).

[0042] See Figures 1 to 4 The pressing part 22 has pressing teeth 221 that bend and extend toward the base plate 1. When the cover plate 2 rotates to the top surface of the base plate 1 by means of the first bending parts 3 at both ends of the base plate 1, and one or more wire harnesses 4 are inserted into the wire pressing space between the cover plate 2 and the base plate 1 in the second direction, the pressing teeth 221 at least partially contact and abut against the surface of the wire harnesses 4 in the third direction.

[0043] See Figure 3 The pressure tooth 221 may be configured with a pressure tip capable of contacting the wire harness at four points, along a line, and / or on a surface. For example, the bent end of the pressure tooth 221 may be configured with a triangular tip (e.g., Figure 3Therefore, when the pressure tooth 221 abuts against the wire harness 4, the bent end of the pressure tooth 221 makes approximately point contact with the surface of the wire harness 4. Alternatively, the bent end of the pressure tooth 221 is constructed as a trapezoidal tip (not shown in the figure), so that when the pressure tooth 221 abuts against the wire harness 4, the bent end of the pressure tooth 221 makes approximately line contact with the surface of the wire harness 4. Or, the bent end of the pressure tooth 221 is constructed as a tip with a significant thickness (not shown in the figure), so that when the pressure tooth 221 abuts against the wire harness 4, the bent end of the pressure tooth 221 makes approximately surface contact with the surface of the wire harness 4.

[0044] In other embodiments, the pressing teeth 221 may have two or more pressing tips that are different from each other. For example, at least a portion of the contact end of the pressing teeth 221 may be configured as a triangular tip, while at least another portion of the contact end may be configured as a trapezoidal tip. Thus, when the pressing teeth 221 contact and abut against the surface of the wire harness 4, the multiple pressing tips can provide different forms of clamping force to the wire harness 4.

[0045] In the accompanying drawings and embodiments of this application, the pressing teeth 221 are described as having a pointed tooth-shaped structure, but this is only an illustrative example for ease of understanding and explanation, and is not a specific limitation on the structure of this application. In other embodiments, the pressing teeth 221 may also be constructed in other possible geometries, and their purpose is to fix the wire harness 4 by abutting and pressing it against the surface of the base plate 1 and to prevent the wire harness 4 from slipping off when the cover plate 1 is pressed against the surface of the base plate 1 in a third direction.

[0046] According to a preferred embodiment, such as Figures 1 to 5 As shown, a locking groove 23 is formed on one of the cover plates 2 at both ends of the base plate 1. A locking block 24 is formed on the other cover plate 2 at both ends of the base plate 1. The locking groove 23 and the locking block 24 can be configured to fit each other in shape / structure. Specifically, when the cover plates 2 at both ends of the base plate 1 are rotated to the top surface of the base plate 1 by means of the rotatable first bend 3, the two cover plates 2 can be connected adaptively by means of the locking groove 23 and the locking block 24, which fit each other in shape, so that the two cover plates 2 are combined into one piece to be arranged or even attached to the surface of the wire harness 4. In particular, the setting of the locking groove 23 and the locking block 24 can be used to prevent the two bent surfaces (i.e., cover plates 2) from misaligning, ensuring that the entire terminal interface is flush after bending (e.g., Figure 2 ).

[0047] Figures 6 to 9 Another preferred embodiment of the terminal interface provided in this application is shown, and the similarities will not be repeated. For example... Figure 8 and Figure 9As shown, in this embodiment, a rotatable second bend 5 is constructed at one end of the base plate 1 along the second direction. Specifically, when the wire harness 4 is inserted into the wire pressing space between the base plate 1 and the cover plate 2 along the second direction, the second bend 5 can be rotated to the end of the wire harness 4 to contact and abut against the wire harness 4 along the second direction. For example, when the wire harness 4 is... Figure 4 When inserted in the indicated direction, the second bend 5, which is provided at the insertion end of the wire harness on the base plate 1, can be rotated to block the wire harness 4 from coming out of the pressure space.

[0048] like Figure 6 As shown, in this embodiment, one or more bending holes 321 can be constructed on the first bending portions 3 at both ends of the base plate 1, extending toward the wire harness 4. Specifically, one or more bending holes 321 can be formed on the first arc-shaped plate 32. For example, the bending holes 321 can be formed on one of the first arc-shaped plates 32. Alternatively, bending holes 321 can be formed on both first arc-shaped plates 32. In particular, these bending holes 321 reduce the mechanical strength at the first bending portion 3, making the folding between the cover plate 2 and the base plate 1 easier to perform.

[0049] like Figure 9 As shown, similar to the first bend 3, the second bend 5 may include a second flat plate 52 and a second arcuate plate 51 formed between the second flat plate 52 and the base plate 1. Both the second flat plate 52 and the second arcuate plate 51 extend along a first direction of the base plate 1. Specifically, when the second bend 5 is rotated and abuts against the wire harness 4 along a second direction, the second bend 5, composed of the second flat plate 52 and the second arcuate plate 51, can partially cover the insertion end of the wire harness 4. Preferably, in other embodiments, the second bend 5 may be configured the same as the first bend 3, i.e., the second bend 5 almost completely covers the insertion end of the wire harness 4.

[0050] In some alternative embodiments, the second bending portion 5 may comprise a plurality of independent second bending units. That is, each second bending unit may be driven independently. The plurality of independent second bending units may be arranged at intervals from each other along a first direction of the base plate 1. Furthermore, the plurality of independent second bending units may be configured to be different from each other, for example, having different lengths.

[0051] like Figure 6 and Figure 7 As shown, in this embodiment, each cover plate 2 at both ends of the base plate 1 is constructed with a plurality of alternately arranged engaging grooves 23 and engaging blocks 24. The engaging grooves 23 and engaging blocks 24 are shape-fitted to each other. When the cover plates 2 at both ends of the base plate 1 are rotated to the top surface of the base plate 1 via the first bending portion 3, the two cover plates 2 can be connected adaptively by means of the mutually shape-fitting engaging grooves 23 and engaging blocks 24. For example, with Figure 7When the two cover plates 2 are joined as shown, each engagement groove 23 on one cover plate 2 engages with each engagement block 24 on the other cover plate 2 that is positioned opposite each other, and / or each engagement groove 24 on one cover plate 2 engages with each engagement groove 23 on the other cover plate 2 that is positioned opposite each other.
