It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] Traditional electrical connections between equipment and wiring harnesses involve connecting two terminals to the equipment and mating parts separately, and then fixing these two terminals together by soldering. This soldering method is complex, has a high failure rate, and increases the overall product defect rate, thus raising costs. Furthermore, the high manufacturing cost of the two terminals also increases the material cost of the electrical connection between the two components.

[0037] Based on this, the integrated terminal provided by this utility model has a base as the basic support structure for the integrated terminal, providing installation support for other components. Two protruding snap-fit ​​structures are provided on the top of the base, which are respectively connected to the two sides in the width direction of the base and are symmetrically arranged to achieve snap-fit ​​engagement with the mating parts, thereby fixing the integrated terminal to the mating parts. The snap-fit ​​hooks in the snap-fit ​​assembly are used to engage with at least the front end of the conductor covering the wire, thereby connecting the conductor to the integrated terminal. Thus, the integrated terminal can realize the electrical connection between the wire and the mating parts, reducing the cost of the electrical connection between the two.

[0038] See Figures 1 to 4 One embodiment of this application provides an integrated terminal, which may include a base 110 and a hook assembly connected to the base 110. Two protruding snap-fit ​​structures 120 are provided on the upper part of the base 110, and the two protruding snap-fit ​​structures 120 are respectively connected to two sides in the width direction of the base 110. The two protruding snap-fit ​​structures 120 are respectively used to achieve snap-fit ​​engagement with mating parts. The hook assembly includes at least one hook. The hook is used to engage with at least the front end of the conductor covering the wire.

[0039] In this embodiment, the base 110 and the two protruding snap-fit ​​structures 120 cooperate, with the base 110 serving as the load-bearing core and the two protruding snap-fit ​​structures 120 symmetrically distributed on both sides of the width direction of the base 110, which can form a double-sided snap-fit ​​with the mating parts, effectively avoiding tilting or loosening caused by unilateral force, and realizing a fixed connection with the mating parts.

[0040] In this embodiment, the mating component can be an aluminum strip of a PTC electric heating assembly. The aluminum strip includes a first plane and a second plane arranged opposite to each other. The inner sides of the two snap-fit ​​structures are in contact with the first plane of the aluminum strip, and the base 110 is in contact with the second plane of the aluminum strip. The mating of the base 110 and the two protruding snap-fit ​​structures 120 can wrap around the aluminum strip to achieve the connection between the mating component and the integrated terminal.

[0041] In this embodiment, the hook assembly is designed directly for the front end of the conductor. It replaces the traditional screw fastening or welding with a snap-fit ​​method, and the conductor can be fixed without additional tools. At the same time, it achieves the simultaneous realization of mechanical fixation and electrical connection, which solves the defects of the prior art that are cumbersome to assemble and not suitable for mass production.

[0042] In the above embodiments, the base 110 serves as the basic support structure for the integrated terminal, providing installation support for other components. Two protruding snap-fit ​​structures 120 are provided above the base 110. The two protruding snap-fit ​​structures 120 are respectively connected to two sides in the width direction of the base 110 and are symmetrically arranged to achieve snap-fit ​​engagement with the mating parts, thereby fixing the integrated terminal to the mating parts. The snap-fit ​​hooks in the snap-fit ​​hook assembly are used to engage with at least the front end of the conductor covering the wire, thereby connecting the conductor to the integrated terminal. Thus, the integrated terminal can achieve electrical connection between the wire and the mating parts, reducing the cost of electrical connection between the two.

[0043] Furthermore, by combining two terminals, each used for connecting to a corresponding component, into a single integrated terminal, the material cost for making electrical connections between the two can be reduced.

[0044] Furthermore, traditional methods are affected by the skill level of electrical connection operators, resulting in a high soldering defect rate when soldering two terminals. The integrated terminal design eliminates the soldering process, reducing the product defect rate caused by electrical connections and also lowering labor costs.

[0045] In some embodiments, the inner side of any of the protruding snap-fit ​​structures 120 includes at least one first barb structure 121. The first barb structure 121 points towards the base 110 and is used to pierce the first plane of the mating member.

[0046] In this embodiment, the first barb structure 121 is disposed inside the protruding snap-fit ​​structure 120 and points towards the base 110. When the protruding snap-fit ​​structure 120 is inserted into the mating part, the barb will actively pierce into the first plane of the mating part, forming a limit along the snap-fit ​​direction, preventing the integrated terminal and the mating part from being displaced relative to each other along the length direction of the integrated terminal.

[0047] In addition, the barbed structure can increase the contact stress with the mating parts, transforming surface contact into point contact (insertion point), improving the anti-slip capability of the snap-fit ​​surface, and making up for the shortcomings of the simple protrusion snap-fit ​​in the prior art, which relies solely on friction for fixation and is prone to loosening.

[0048] In some embodiments, any one of the protruding snap-fit ​​structures 120 includes two first barb structures 121; the two first barb structures 121 are arranged at intervals along the length direction of the base 110, and the length direction is perpendicular to the width direction.

[0049] In this embodiment, each protruding snap-fit ​​structure 120 is provided with two first barbs, which increases the number of insertion points with the first plane of the mating part, so that the snap-fit ​​stress is evenly distributed to two points, reducing the load-bearing capacity of a single barb and improving the fatigue resistance of the snap-fit ​​structure.

[0050] In this embodiment, two barbs are arranged at intervals along the length direction of the base 110 (perpendicular to the width direction), covering the length range of the protruding snap-fit ​​structure 120, avoiding snap-fit ​​failure caused by local deformation or uneven force of the aluminum strip. Compared with a single barb, the locking range is wider and the stability is stronger.

[0051] In some embodiments, the inner side of the base 110 includes at least one second barb structure 111;

[0052] The second barb structure 111 points to the protruding snap-fit ​​structure 120 and is used to insert into the second plane of the mating member. The second plane is disposed opposite to the first plane.

[0053] In this embodiment, the second barb structure 111 is disposed inside the base 110 and points towards the protruding snap-fit ​​structure 120, forming a reverse orientation with the first barb structure 121, acting on the opposite first and second planes of the mating component, respectively. This bidirectional insertion design clamps the mating component between the two barb structures, forming a "bidirectional locking," which not only resists the separation force along the snap-fit ​​direction but also suppresses vertical / horizontal movement between the terminal and the mating component, forming all-round snap-fit ​​protection.

[0054] In some embodiments, the number of the second barb structure 111 is four; the line connecting two adjacent second barb structures 111 forms a rectangular area.

[0055] In this embodiment, as Figure 3 As shown, the four second barb structures 111 are arranged in a rectangular region. In other words, two parallel second barb structures 111 are respectively provided on both sides of the width direction of the base 110. The rectangular structure has good mechanical stability, which can evenly distribute the stress transmitted from the mating parts to the base 110 to the four barb points, avoiding local stress concentration caused by a single barb or asymmetrical distribution.

[0056] In some embodiments, a first circular through hole 122 is provided on the outer side of the protruding snap-fit ​​structure 120. The first circular through hole 122 and the first barb structure 121 are located at the same position on the protruding snap-fit ​​structure 120.

[0057] In this embodiment, the first circular through hole 122 and the first barb structure 121 are located at the same position, serving as clearance space for the formation of the first barb during processing. In other words, a conical piercing can be performed from the outside to the inside of the protruding engagement structure 120, thereby piercing the protruding engagement structure 120 to form a circular through hole in it. The material generated by the first circular through hole 122 formed by the conical piercing forms the first barb structure 121 on the inner surface of the protruding engagement structure 120. This avoids material accumulation or incomplete forming during barb processing, making it suitable for one-piece molding processes and improving the processing yield.

[0058] In addition, during assembly, the first circular through hole 122 can serve as a visual positioning reference, allowing operators to quickly align the mating parts with the corresponding positioning points through the through hole, thus avoiding jamming failures caused by misalignment between the barbs and the mating parts, and improving assembly efficiency.

[0059] In some embodiments, a second circular through hole 112 is provided on the outer side of the base 110. The second circular through hole 112 and the second barb structure 111 are located at the same position on the base 110.

[0060] In this embodiment, the second circular through-hole 112 and the second barb structure 111 are located at the same position, serving as clearance space for the formation of the second barb during processing. In other words, a conical piercing can be performed from the outside to the inside of the base 110 to pierce the base 110 and form a circular through-hole in it. The material generated by the second circular through-hole 112 formed by the conical piercing forms the second barb structure 111 on the inner surface of the base 110. This avoids the problems of material accumulation or incomplete forming during barb processing, making it suitable for one-piece molding processes and improving the processing qualification rate.

[0061] In addition, during assembly, the second circular through hole 112 can serve as a visual positioning reference, allowing operators to quickly align the mating parts with their corresponding positioning points through the through hole, thus avoiding jamming failures caused by misalignment between the barbs and the mating parts, and improving assembly efficiency.

[0062] In some embodiments, the hook assembly includes two U-shaped hooks arranged side by side along the length direction of the base 110. The length direction is perpendicular to the width direction.

[0063] In this embodiment, the U-shaped hook has excellent elastic deformation capability, enabling rapid insertion and removal of the conductor through its own deformation without the need for additional tools, thus solving the problem of low efficiency in traditional connection methods. Furthermore, the U-shaped structure can form a wraparound enclosure around the conductor, increasing the contact area and ensuring the stability of the electrical connection while preventing axial movement of the conductor.

[0064] In this embodiment, two U-shaped hooks are arranged side by side along the length of the base 110, working together on the front end of the same conductor to form a double fixation. Compared with a single hook, this not only increases the total contact area with the conductor and reduces the contact resistance to ensure conductivity stability, but also applies clamping force to the conductor from different points.

[0065] In some embodiments, the base 110 and the hook assembly are connected by a connector 140. The base 110, the connector 140, and the hook assembly are integrally formed.

[0066] In this embodiment, the connector 140 serves as a transitional connection between the base 110 and the hook assembly, solving the problem of force transmission when the two are directly connected and avoiding stress concentration.

[0067] In this embodiment, the base 110, connector 140, and hook assembly are manufactured using a one-piece molding process, rather than a multi-part splicing method. This eliminates gaps or connection defects at the splicing points, structurally improving the overall load-bearing capacity of the terminal and avoiding the problem of easy breakage at the splicing points in the prior art. Furthermore, one-piece molding reduces multiple processing and assembly steps, lowers errors in component transportation and assembly, improves production efficiency, and reduces the number of parts, thereby reducing production and management costs.

[0068] In some embodiments, the connector 140 is trapezoidal in shape. The two parallel sides of the connector 140 are respectively connected to the base 110 and the hook assembly.

[0069] In this embodiment, since the base 110 and the protruding snap-fit ​​structure 120 are connected by a mating component, and the hook assembly is connected to an electrical wire, the width of the base 110 is greater than the width of the hook assembly. By providing a trapezoidal connector 140, with its two parallel sides connected to the base 110 and the hook assembly respectively, the parallelism and coaxiality of their connection surfaces can be ensured, avoiding uneven stress caused by connection misalignment. This further improves the structural stability of the terminal during long-term use and reduces the risk of fatigue damage caused by stress concentration.

[0070] In some embodiments, the integrated terminal is made of copper.

[0071] In this embodiment, copper is a metallic material with excellent conductivity, which can effectively reduce the contact resistance between the conductor and the terminal, reduce losses during signal or power transmission, meet the core requirements of electrical connection, and make up for the poor conductivity caused by improper material selection in the prior art. In addition, copper has good mechanical strength and toughness, which can meet the shaping requirements during the processing of barb structures (such as the sharpness forming of barbs), and can withstand elastic deformation and stress impact during the snap-fit ​​and insertion process, and is not prone to problems such as barb breakage and base deformation, thus ensuring the structural stability of the terminal for long-term use.

[0072] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0073] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0074] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
