[0030] Embodiment 1

[0031] See also Figure 1 and Figure 2 , this embodiment provides a terminal set 100, including a mounting bar 101, a terminal 102 and a material strip 103;

[0032] At least twenty terminals 102 are arranged in sequence, and a spring height 1021 is provided on the terminal 102 near the front end of the terminal 102. The rear end of each terminal 102 is connected to the mounting strip 101, and the front end is connected to the material strip 103;

[0033] The material strip 103 includes a plurality of component strips 1031 , and each component strip 1031 is provided with eight or less connection positions, and the connection positions are used to connect the front ends of the terminals 102 .

[0034] In a common manufacturing process, the mounting strip 101 , the terminal 102 and the material strip 103 are integrally manufactured from a whole piece of rectangular thin-walled material by punching and cutting, and thus, the mounting strip 101 and the material strip 103 are both in sheet form.

[0035] The mounting strip 101 is a component used to fix and support the terminal 102, and it plays the following roles during the installation process: helping to firmly fix the terminal 102 in its installation position to prevent it from loosening or shifting during use; providing additional support for the terminal 102 to enhance its mechanical strength and ensure that the terminal 102 can remain stable under the action of external forces; the mounting strip 101 can be designed into a specific shape to ensure that the terminal 102 can only be inserted in the correct direction and manner to avoid misinsertion.

[0036] The material strip 103 is mainly produced during the stamping or cutting process. It is used to ensure the accuracy of the shape and size of the terminal 102 during stamping and to ensure the integrity and accuracy of the cutting during cutting. Its existence is mainly to facilitate production and processing.

[0037] The lengths of the mounting strip 101 and the material strip 103 are the same, and the widths of the mounting strip 101 and the material strip 103 are different according to their different functions, and the width of the mounting strip 101 is greater than the width of the material strip 103. The wider width enables the mounting strip 101 to more effectively support the terminal 102, especially in the case of a large mechanical load or vibration, providing a stronger support effect and ensuring reliability in long-term use.

[0038] The width of the material strip 103 is relatively narrow, and the whole is a long thin-walled piece. For a long thin-walled piece, the longer the length, the greater the deformation of the thin-walled piece when subjected to force. The elasticity of the thin-walled piece is proportional to the length, and the longer the length, the greater the elasticity.

[0039] The rear end of the terminal 102 is connected to the mounting strip 101, that is, the vertical distance between the rear end of each terminal 102 and the mounting strip 101 is 0. A spring height 1021 is set on the terminal 102 near the front end of the terminal 102, and the position of the spring height 1021 is bent and deformed. Since at least twenty terminals 102 are arranged in sequence, the deformation amount of the spring height 1021 position of each terminal 102 will be different, resulting in different vertical distances between the front end of each terminal 102 and the mounting strip 101. The long strip of material 103 has greater elasticity. The material strip 103 is connected to the front end of the terminal 102 and is driven by the terminal 102 to deform, which ultimately leads to inconsistent heights of the spring height 1021 of the terminal 102.

[0040] The material strip 103 is divided into multiple groups of sub-strips 1031, and each group of sub-strips 1031 is provided with less than or equal to eight connection positions for connecting the terminals 102, that is, the total length of the material strip 103 remains unchanged, but the length of the sub-strips 1031 constituting the material strip 103 is shortened compared to the total length of the material strip 103. The specific length of each sub-strip 1031 is adapted according to the number of terminals 102 connected to each sub-strip 1031, and each sub-strip 1031 is connected with less than or equal to eight connecting terminals 102, so that the sub-strip 1031 can have sufficient rigidity to ensure that it does not deform. The sub-strip 1031 is short in length, low in elasticity, and not easy to deform, so that the terminal 102 is deformed to adapt to the sub-strip 1031, thereby ensuring the consistency of the height of the elastic height 1021 of each terminal 102.

[0041] In this embodiment, since the material strip 103 includes multiple component strips 1031, each component strip 1031 is provided with less than or equal to eight connection positions for connecting the front end of the terminal 102. The sub-strip 1031 is short in length, low in elasticity, good in rigidity, and not easy to deform, thereby fixing the connection position between the front end of the terminal 102 and the sub-strip 1031, limiting the deformation amount of the elastic height 1021, and ensuring the consistency of the height of the elastic height 1021 of each terminal 102.

[0042] Embodiment 2

[0043] See also Figure 2 On the basis of the first embodiment, a plurality of first connection protrusions are provided on the connection position, and the terminal 102 is connected to the strip 1031 through the first connection protrusions.

[0044] The first connection protrusion clarifies the connection position between the terminal 102 and the sub-band 1031, so that the connection between the two has a clear boundary, which is easy to identify and distinguish. In addition, the connection through the first connection protrusion can disperse the stress between the terminal 102 and the sub-band 1031, reducing material fatigue and damage caused by stress concentration.

[0045] In one embodiment, the width of the first connection protrusion at the connection point with the sub-ribbon 1031 is greater than the width at the connection point with the terminal 102. The contact area between the sub-ribbon 1031 and the protrusion can be increased, thereby enhancing the stability of the connection.

[0046] In one embodiment, the width of the connection between the first connection protrusion and the terminal 102 is smaller than the width of the front end of the terminal 102. Since the material strip 103 is mainly produced during the stamping or cutting process, its existence is mainly for the convenience of production and processing, but it needs to be removed in the final product. Therefore, the width of the connection between the terminal 102 is smaller than the width of the front end of the terminal 102, reducing the connection area between the terminal 102 and the sub-strip 1031, and facilitating the subsequent removal of the sub-strip 1031.

[0047] In one embodiment, the connection position between the first connection protrusion and the sub-belt 1031 is rounded, which helps to disperse the stress at the connection, reduce the stress concentration problem caused by the sharp edge, and enhance the stability of the connection.

[0048] Embodiment 3

[0049] See also Figure 2 Based on the first embodiment, gaps are set between adjacent sub-bands 1031.

[0050] Providing gaps between adjacent sub-strips 1031 helps to reduce mutual interference, ensure the independence of each sub-strip 1031, avoid friction and collision between sub-strips 1031, improve tensile and shear resistance, and thus improve the overall stability of the terminal 102 group.

[0051] In one embodiment, the gap between adjacent sub-strips 1031 is not less than 0.5 mm. 0.5 mm is a safe distance to prevent the sub-strips 1031 from contacting each other.

[0052] Embodiment 4

[0053] See also Figure 2 On the basis of the first embodiment, a plurality of second connection protrusions are provided on the mounting bar 101, and the terminal 102 is connected to the mounting bar 101 through the second connection protrusions. The beneficial effects of the second connection protrusions are similar to those of the first connection protrusions, and will not be described in detail here.

[0054] In one embodiment, the connection position between the second connection protrusion and the mounting bar 101 is rounded, which helps to disperse the stress at the connection, reduce the stress concentration problem caused by the sharp edge, and enhance the stability of the connection.

[0055] Embodiment 5

[0056] See also Figure 3 On the basis of the first embodiment, the terminal assembly 100 further includes an injection molded part 104 , which is connected to the terminal 102 by injection molding, and an extending direction of the injection molded part 104 is consistent with an extending direction of the mounting bar 101 .

[0057] An injection molded part 104 is added to the terminal group 100 and connected to the terminal 102 by injection molding. Commonly used injection molding materials such as polycarbonate, acrylonitrile-butadiene-styrene copolymer and polypropylene have poor elasticity and are not easy to deform. They can provide additional fixation and support to improve the stability of the overall connection.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
