Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall concept of this utility model and should not be construed as a limitation thereof.

[0022] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0023] According to a general technical concept of the present invention, a terminal is provided. The terminal includes: a main body portion formed in the shape of a plate, having front and rear sides opposite to each other in its thickness direction, left and right sides opposite to each other in its width direction, and a top and bottom end opposite to each other in its height direction; a pair of outer support portions respectively connected to the opposite sides of the main body portion in the width direction, extending forward and backward respectively, and adapted to be supported on the upper surface of a circuit board; and a plurality of feet located between the pair of outer support portions and extending downward from the bottom end of the main body portion, each foot being adapted to be inserted into a mounting hole of the circuit board.

[0024] According to another general technical concept of this utility model, an electrical connection assembly is provided. The electrical connection assembly includes: a circuit board having a plurality of mounting holes; and the aforementioned terminals, mounted on the circuit board, each terminal inserted into one of the mounting holes.

[0025] First Embodiment Figures 1 to 3 This illustrates a first embodiment according to the present invention. Figure 1 A perspective view of an electrical connection assembly according to a first embodiment of the present invention is shown; Figure 2 This diagram shows an exploded view of an electrical connection assembly according to a first embodiment of the present invention. Figure 3 This shows a front view schematic diagram of terminal 1 according to the first embodiment of the present invention.

[0026] like Figures 1 to 3 As shown, in an exemplary embodiment of the present invention, a terminal 1 is disclosed. The terminal 1 includes a main body 10, a pair of outer support portions 11, and a plurality of feet 12.

[0027] The main body 10 is plate-shaped, having front and rear sides opposite each other in its thickness direction X, left and right sides opposite each other in its width direction Y, and top and bottom ends opposite each other in its height direction Z. A pair of outer support portions 11 are respectively connected to opposite sides in the width direction Y of the main body 10, extending forward and backward respectively, and adapted to support the upper surface of the circuit board 2. A plurality of feet 12 are located between the pair of outer support portions 11 and extend downward from the bottom end of the main body 10, each foot 12 being adapted to be inserted into a mounting hole 21 of the circuit board 2.

[0028] The terminal 1 is supported on the upper surface of the circuit board 2 by a pair of outer support parts 11, which can enhance the structural strength and stability of the terminal 1 after it is connected to the circuit board (e.g., PCB board), improve its resistance to external forces and torsional forces, not only increase the durability of the product, but also ensure its reliability in various application environments. The terminal 1 does not require the plate-shaped main body 10 to be inserted into the circuit board 2; instead, it is positioned and fixed by inserting multiple feet 12 into the mounting holes 21 of the circuit board 2. This allows the mounting holes 21 of the corresponding circuit board 2 to be set to a circular or other shape that is easily recognized by an automatic pin insertion machine, thereby enabling automated production, improving production efficiency, reducing labor costs, minimizing human error, and ensuring product consistency and quality.

[0029] The terminal 1 also includes a central front support portion 13 and a central rear support portion 14. The central front support portion 13 is located between the plurality of feet 12 and extends forward from the bottom end of the main body portion 10. The central rear support portion 14 is located between the plurality of feet 12 and extends rearward from the bottom end of the main body portion 10. The central front support portion 13 and the central rear support portion 14 are adapted to be supported on the upper surface of the circuit board 2.

[0030] A pair of outer support portions 11, a middle front support portion 13, and a middle rear support portion 14 extend forward and backward alternately in the width direction Y. The bottom ends of the outer support portions 11, the middle front support portion 13, and the middle rear support portion 14 respectively have a first support bottom surface 110, a second support bottom surface 130, and a third support bottom surface 140. The first support bottom surface 110, the second support bottom surface 130, and the third support bottom surface 140 are located in the same plane, perpendicular to the height direction Z, and are adapted to be supported on the upper surface of the circuit board 2.

[0031] By providing multiple alternating front and rear support parts at its bottom, the terminal 1 can further enhance the structural strength and stability after being connected to the circuit board, improve its resistance to external forces and torsional forces, and increase the durability and reliability of the product.

[0032] The plurality of feet 12 include two outer feet 12a and a middle foot 12b located between the two outer feet 12a, a middle front support 13 located between the middle foot 12b and one of the outer feet 12a, and a middle rear support 14 located between the middle foot 12b and the other outer foot 12a.

[0033] In one embodiment, the spacing between the three legs 12 of terminal 1 is 2.5 mm, which conforms to industry standard specifications and is compatible with most existing automatic pin insertion machines, thereby expanding the range of applications and improving production efficiency.

[0034] However, the present invention is not limited to the embodiments shown in the figure. For example, in some other embodiments, the spacing between the feet 12 can be other values; in still other embodiments, depending on the size and strength requirements of the terminal 1, the middle foot 12b may not be provided, or multiple middle feet 12b may be provided, and the number of middle front support 13 and middle rear support 14 may be increased accordingly.

[0035] See also Figures 1 to 3 A pair of outer support portions 11 are formed by bending forward and backward from two opposite sides of the main body portion 10 in the width direction Y.

[0036] A pair of outer support portions 11 extend a distance from the left and right sides of the main body 10 to the left and right sides respectively, such that the first support bottom surface 110 of the outer support portion 11 extends a distance to the left or right relative to the bottom end of the main body 10. For example, at least a portion of the outer support portion 11 is arc-shaped, so that the outer support portion 11 has a larger support range, thereby being able to support the circuit board 2 more stably and reliably.

[0037] However, the present invention is not limited to the embodiments shown in the figure. For example, in some other embodiments, a pair of outer support portions 11 may be connected to the left and right sides of the bottom end of the main body portion 10 respectively; in still other embodiments, the outer support portion 11 may be formed as a flat plate or composed of multiple flat plates at different angles.

[0038] See also Figures 1 to 3 The foot 12 is adapted to be fixed to the circuit board 2 by soldering.

[0039] Terminal 1 is a one-piece stamped part, which can reduce manufacturing costs and improve manufacturing efficiency.

[0040] In another exemplary embodiment of this utility model, an electrical connection assembly is also disclosed. The electrical connection assembly includes a circuit board 2 and the aforementioned terminals 1. The circuit board 2 has a plurality of mounting holes 21. The terminals 1 are mounted on the circuit board 2, with each pin 12 of the terminals 1 inserted into a mounting hole 21 of the circuit board 2.

[0041] Second Embodiment Figure 4 and Figure 5 This illustrates a second embodiment according to the present invention. Figure 4 A perspective view of an electrical connection assembly according to a second embodiment of the present invention is shown; Figure 5 This diagram shows a perspective view of terminal 1 according to a second embodiment of the present invention.

[0042] and Figures 1 to 3 Compared to the first embodiment shown, Figure 4 and Figure 5 The main difference in the second embodiment shown is that the foot 12 of the terminal 1 is adapted to be fixed in the mounting hole 21 by interference fit, thereby further simplifying the production process, improving production efficiency and reducing costs.

[0043] Specifically, the foot 12 includes a front protrusion 121 and a rear protrusion 122 that protrude forward and backward respectively. The front protrusion 121 and the rear protrusion 122 are offset in the width direction Y and are adapted to press against the inner wall of the mounting hole 21 by elastic deformation, thereby simply realizing the press-fit between the terminal 1 and the circuit board 2.

[0044] The other technical features of the second embodiment are basically the same as those of the first embodiment, and can be referred to accordingly. Figures 1 to 3 The first embodiment shown.

[0045] In another exemplary embodiment of this utility model, an electrical connection component is also disclosed.

Terminal 1 is mounted on the circuit board 2, and each leg 12 of terminal 1 is inserted into a mounting hole 21 of the circuit board 2.

[0046] Third Embodiment Figure 6 This shows a side view of terminal 1 according to a third embodiment of the present invention. Figures 1 to 3 Compared to the first embodiment shown, Figure 6 The main difference in the third embodiment shown is that the foot 12 of the terminal 1 is adapted to be fixed in the mounting hole 21 by interference fit, thereby further simplifying the production process, improving production efficiency and reducing costs.

[0047] Specifically, the foot 12 includes a front elastic arm 123 and a rear elastic arm 124 protruding forward and backward, respectively, with an opening 125 formed between the rear side of the front elastic arm 123 and the front side of the rear elastic arm 124. The opening 125 provides space for deformation of the front elastic arm 123 and the rear elastic arm 124, allowing them to easily undergo elastic deformation under the pressure of the mounting hole 21, thus facilitating the press-fit between the terminal 1 and the circuit board 2. In the width direction Y, the front elastic arm 123 and the rear elastic arm 124 can be aligned with each other or staggered.

[0048] The other technical features of the third embodiment are basically the same as those of the first embodiment, and can be referred to accordingly. Figures 1 to 3 The first embodiment shown.

[0049] In another exemplary embodiment of this utility model, an electrical connection component is also disclosed. This electrical connection component includes, as shown below: Figure 4 and Figure 5 The circuit board 2 shown and as shown Figure 6 Terminal 1 is shown.
