Description

Technical Field

[0001] This utility model relates to the field of pin technology, and in particular to a pin structure. Background Technology

[0002] Electronic pins are widely used in automotive connector terminals, various PCB circuit boards, computer connector terminals, and other electronic components.

[0003] The pins on existing terminals require a flatness control of up to 0.1mm when connecting the terminal pins to the PCB and undergoing reflow soldering. This is very difficult to process. If the dimensions are exceeded, the soldering will result in poor solder joints and a rough surface, leading to weak electrical connections and reduced production efficiency.

[0004] For example, a patent entitled "A PIN Pin" was published on September 5, 2012, with publication number CN202423613U. It includes a PIN pin body and two ends of the PIN pin. The two ends of the PIN pin are tapered tips. Although the tapered tips of the PIN pin make it easy to insert and remove, save installation time, and improve production efficiency, the soldering may result in poor soldering, which may lead to weak electrical connections and thus reduce production efficiency. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose a pin structure to solve the problem of reduced production efficiency.

[0006] To achieve the above objectives, this utility model provides a pin structure, including a body comprising an upper section, a middle section, and a pin segment. The upper section is connected to the pin segment via the middle section. The pin segment includes a fisheye pin with a fisheye hole. A first upper arc strip and a second upper arc strip, both connected to the lower end of the middle section, are respectively connected to the front and rear sides of the fisheye hole. The protrusions of the first and second upper arc strips are both located away from the fisheye hole. The lower ends of the first and second upper arc strips both extend into the lower part of the fisheye hole.

[0007] Optionally, the lower end of the first upper arc strip is connected to a first lower arc strip located below the second upper arc strip, and the lower end of the first lower arc strip is located directly below the fisheye pin.

[0008] Optionally, the lower end of the second upper arc strip is connected to a second lower arc strip located below the first upper arc strip, and the lower end of the second lower arc strip is located between the lower end of the fisheye needle foot and the lower end of the first lower arc strip.

[0009] Optionally, the first upper arc strip and the first lower arc strip are integrally formed.

[0010] Optionally, the second upper arc strip and the second lower arc strip are integrally formed.

[0011] Optionally, a barbed oblique protrusion is provided on the upper sidewall of the fisheye needle, and the lower end of the barbed oblique protrusion is connected to the sidewall of the fisheye needle.

[0012] Optionally, the horizontal distance between the upper end of the barbed oblique protrusion and the first upper arc strip protrusion is less than the horizontal distance between the lower end of the barbed oblique protrusion and the first upper arc strip protrusion.

[0013] Optionally, the upper sidewall of the fisheye needle is provided with a side groove to accommodate the oblique protrusion of the barb.

[0014] The beneficial effects of this utility model are as follows: The pin structure provided by this utility model uses a fisheye pin made of elastic material. Through the fisheye pin, the first upper arc strip, and the second upper arc strip, the PCB and the pin segment of the pin structure can be connected without soldering, facilitating insertion and improving production efficiency. The fisheye pin facilitates connection between the pin structure and the PCB after insertion into the insertion hole on the PCB. The first and second upper arc strips reduce the possibility of the pin structure loosening from the PCB. Furthermore, the lower ends of the first and second upper arc strips extend into the lower part of the fisheye hole, effectively filling the lower part of the fisheye hole, further reducing the possibility of the pin structure loosening from the PCB. This improves the durability and effectiveness of the connection between the pin structure and the PCB, reduces the possibility of detachment or loosening, increases connection strength, and also enhances stability and buffering capacity.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figures 1 to 3 As shown, a pin structure is a commonly used pin in terminal blocks. The term "pin" is common knowledge in the industry and will not cause misunderstanding. The pin structure provided in this embodiment includes a body 1, which includes an upper section 2, a middle section 3, and a pin segment 4. The upper section 2 is connected to the pin segment 4 through the middle section 3. The end of the upper section 2 is provided with a tapered tip. The pin segment 4 includes a fisheye pin 5, which has a fisheye hole 6. The front and rear sides of the fisheye hole 6 are respectively connected to a first upper arc strip 8 and a second upper arc strip 10, both of which are connected to the lower end of the middle section 3. The protrusions of the first upper arc strip 8 and the second upper arc strip 10 are both located away from the fisheye hole 6. The lower ends of the first upper arc strip 8 and the second upper arc strip 10 both extend into the lower part of the fisheye hole 6.

[0024] like Figure 4 As shown, a PCB is provided below the pin structure, and the PCB has an insertion hole for easy insertion of the pin segment 4 in the pin structure.

[0025] The fisheye pin 5 is made of elastic material. Through the fisheye pin 5, the first upper arc strip 8, and the second upper arc strip 10, the PCB can be connected to the pin segment 4 of the pin structure without soldering, facilitating insertion. The pin segment 4 can be smoothly inserted. The fisheye pin 5, after being inserted into the insertion hole, facilitates the connection between the pin structure and the PCB. The first upper arc strip 8 and the second upper arc strip 10 reduce the possibility of the pin structure loosening from the PCB. Furthermore, the lower ends of the first upper arc strip 8 and the second upper arc strip 10 extend into the lower part of the fisheye hole 6, effectively filling the lower part of the fisheye hole 6, further reducing the possibility of the pin structure loosening from the PCB. This improves the durability and effectiveness of the connection between the pin structure and the PCB, reduces the possibility of detachment or loosening, increases connection strength, and also enhances stability and buffering capacity.

[0026] The lower end of the first upper arc strip 8 is connected to a first lower arc strip 9 located below the second upper arc strip 10. The lower end of the first lower arc strip 9 is located directly below the fisheye pin 5. The first lower arc strip 9 has an arched structure, which improves stability and increases buffering capacity.

[0027] The lower end of the second upper arc strip 10 is connected to a second lower arc strip 11 located below the first upper arc strip 8. The lower end of the second lower arc strip 11 is located between the lower end of the fisheye pin 5 and the lower end of the first lower arc strip 9. The first lower arc strip 9 has an arched structure, which improves stability and increases buffering capacity. In addition, the second lower arc strip 11 is located above the first lower arc strip 9, which facilitates the pin segment 4 to be smoothly inserted into the insertion hole on the PCB.

[0028] The first upper arc strip 8 and the first lower arc strip 9 are integrally formed to improve structural strength and enhance damage resistance.

[0029] The second upper arc strip 10 and the second lower arc strip 11 are integrally formed to improve structural strength and enhance damage resistance.

[0030] The upper sidewall of the fisheye pin 5 is provided with a barbed oblique protrusion 7. The lower end of the barbed oblique protrusion 7 is connected to the sidewall of the fisheye pin 5. The barbed oblique protrusion 7 can effectively prevent the fisheye pin 5 from detaching from the PCB during normal use.

[0031] The horizontal distance between the upper end of the barbed protrusion 7 and the protrusion of the first upper arc strip 8 is less than the horizontal distance between the lower end of the barbed protrusion 7 and the protrusion of the first upper arc strip 8. The barbed protrusion 7 is inclined, and the barbed protrusion 7 is set so that it can cooperate with the insertion hole opened on the PCB. The inclined setting of the barbed protrusion 7 can reduce the possibility of the pin structure rotating in the insertion hole on the PCB.

[0032] The upper side wall of the fisheye needle 5 is provided with a side groove to accommodate the barbed oblique protrusion 7, which facilitates the accommodation of the barbed oblique protrusion 7.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0034] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
