[0046] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0047] Figures 1 to 6 A terminal according to the utility model is shown, and the terminal includes an elastic part 100, two connecting parts 110 and a spring piece 120. The elastic part 100 is provided with a telescopic hole 101 to form a hollow structure. The two connecting parts 110 are arranged at both ends of the elastic part 100 along the axial direction Z, and the connecting part 110 is used to be sleeved to the part to be connected. The first end of the spring piece 120 is connected to the connecting part 110, and the second end of the spring piece 120 is a free end. The spring piece 120 is at least partially recessed to the inner side of the connecting part 110 through the telescopic hole 101, and is used to abut against the part to be connected.

[0048] According to the terminal of the utility model, the elastic part 100 is constructed as a hollow structure through the telescopic hole 101, so that the terminal has elasticity, thereby preventing the terminal from material fatigue and plastic deformation during the telescopic process, and improving the performance stability of the terminal. The spring 120 is at least partially recessed into the inner side of the connecting part 110, and can contact the part to be connected, thereby increasing the resistance between the terminal and the part to be connected, and preventing the part to be connected from detaching from the terminal and causing the connector to be interrupted. In addition, the first end of the spring 120 is connected to the connecting part 110, and the second end of the spring 120 is a free end. When installing the part to be connected, the depth of the spring 120 recessed into the inner side of the connecting part 110 can be adjusted by pulling the free end of the spring 120, so that the pressing force of the spring 120 on the part to be connected can be adjusted, thereby adjusting the resistance of the terminal to the part to be connected.

[0049] Reference Figure 1 and Figure 6 The elastic part 100 and the two connecting parts 110 are integrally formed. Figures 2 to 5 As shown, the terminal of the present invention is formed by cutting, bending and welding a plate. The terminal can be cylindrical or bent into a cylindrical structure with a square or rectangular opening. The present invention does not specify the shape of the structure after bending.

[0050] In detail, the telescopic hole 101 of the elastic part 100 includes a first hole 102 and a second hole 103. Figure 2 shows the unfolded state of the terminal before bending. Figure 2 It can be seen that along the axial direction Z and the circumferential direction D of the terminal, the first hole 102 and the second hole 103 are arranged alternately, so that the elastic part 100 is constructed as a hollow structure. Further, the telescopic hole 101 includes an inclined edge 104 and a connecting edge 105. In other words, the inclined edge 104 and the connecting edge 105 are formed by cutting the telescopic hole 101 from the plate. The inclined edge 104 is not parallel to the axial direction Z, and the connecting edge 105 is parallel to the axial direction Z. The four inclined edges 104 are connected end to end in sequence, thereby surrounding the first hole 102. The two connecting edges 105 and the four inclined edges 104 are connected to form the second hole 103. The telescopic hole 101 of the elastic part 100 is composed of the first hole 102 and the second hole 103 arranged alternately, which increases the hollow area of ​​the elastic part 100 and enhances the elasticity of the elastic part 100. The physical structure of the elastic part 100 includes a connecting edge 105 and an inclined edge 104. When the elastic part 100 expands and contracts along the axial direction Z, the angle of the inclined edge 104 relative to the connecting edge 105 changes, so that the elastic part 100 can expand and contract along the axial direction Z.

[0051] Further, the telescopic hole 101 is provided with at least two shapes. Optionally, the first hole 102 is a diamond hole, and the second hole 103 is a hexagonal hole. This structural arrangement is convenient for processing and can also ensure the deformation of the elastic part 100 along the axial direction Z.

[0052] Furthermore, the spring piece 120 includes a first spring piece 121 and a second spring piece 122, and the first spring piece 121 and the second spring piece 122 are arranged along the axial direction Z. For example, along the axial direction Z, the first spring piece 121 is farther away from the elastic part 100 than the second spring piece 122, and the first spring piece 121 can be used as a pre-assembled part to contact the part to be connected (such as a wiring harness), while the second spring piece 122 can be used as a main contact part to contact the part to be connected, which is convenient for installing and reinforcing the terminal and the part to be connected. Since the elastic part 100 is retractable, the first spring piece 121 and the second spring piece 122 can be used to adjust the effective length of the part to be connected to pass through the terminal, so that it can adapt to parts to be connected of different specifications.

[0053] Optionally, along the axial direction Z, the length dimensions of the first spring clip 121 and the second spring clip 122 are different, so that the signal of the terminal can be differentiated when the first spring clip 121 and the second spring clip 122 each contact the connected member separately or simultaneously. Since the resistance of the terminal is different when the first spring clip 121 and the second spring clip 122 each contact the connecting member separately or simultaneously, the terminals with different spring clip 120 contact methods can be used as devices with different resistance values ​​in the signal circuit.

[0054] For example, along the axial direction Z, the length of the first spring piece 121 is less than the length of the second spring piece 122, and the terminal has three modes when contacting the to-be-connected part: only the first spring piece 121 contacts the to-be-connected part; only the second spring piece 122 contacts the to-be-connected part; and both the first spring piece 121 and the second spring piece 122 contact the to-be-connected part. Therefore, the terminal can generate different resistance signals when connected to the circuit due to the different contact modes of the spring piece 120, so that the terminal can be used as a device of the signal circuit.

[0055] Of course, the first spring piece 121 and the second spring piece 122 can also be differentiated in other aspects, so as to make the terminal more functional. For example, the first spring piece 121 and the second spring piece 122 can be selected to be different temperature-sensitive resistor materials or photoresistor materials, so that the terminal can be adjusted to have different temperature-sensitive resistor performance or photoresistor performance when connected to the circuit by different contact modes of the spring piece 120.

[0056] In addition, the first spring piece 121 and the second spring piece 122 can also cooperate with different parts to be connected, and the terminal has different characteristics by the first spring piece 121 and the second spring piece 122 contacting different parts of the parts to be connected. It can be understood that the technical solutions for differentiating the terminal characteristics by the first spring piece 121 and the second spring piece 122 should be within the protection scope of the present utility model.

[0057] Optionally, the spring piece 120 includes at least two first spring pieces 121, and along the circumferential direction D perpendicular to the axial direction Z, at least two first spring pieces 121 are arranged at intervals, so that the first spring piece 121 is in full contact with the part to be connected, so that the connection between the terminal and the part to be connected is more stable. Similarly, optionally, the spring piece 120 includes at least two second spring pieces 122, and along the circumferential direction D perpendicular to the axial direction Z, at least two second spring pieces 122 are arranged at intervals, so that the second spring piece 122 is in full contact with the part to be connected, so that the connection between the terminal and the part to be connected is more stable.

[0058] Optionally, refer to Figure 1 , the size of the spring piece 120 along the axial direction Z can correspond to the size of the telescopic hole 101 along the axial direction Z, which is convenient for integrated cutting of the terminal. For example, along the axial direction Z, the size of the first hole 102 is smaller than the size of the second hole 103, and the first spring piece 121 extends into the first hole 102 along the axial direction Z. The second spring piece 122 extends into the second hole 103 along the axial direction Z, so that the size setting of the spring piece 120 corresponds to the size setting of the telescopic hole 101, and there is no need to cut the telescopic hole 101 and the spring piece 120 at an additional position, which saves cutting and is easy to process.

[0059] Optionally, the connection portion 110 is provided with a weight-reducing hole 111 for reducing the weight of the terminal. The weight-reducing hole 111 may be triangular, so that the connection portion 110 has sufficient structural strength.

[0060] Optionally, the spring sheet 120 is provided with a through slot 123, so as to improve the bending performance of the spring sheet 120. Figure 1 In the embodiment, the second elastic sheet 122 is provided with a through slot 123, and the through slot 123 extends along the axial direction Z, so that the second elastic sheet 122 is easy to bend, thereby facilitating the installation of the terminal and the component to be connected.

[0061] Optionally, refer to Figure 5The terminal includes a first edge 130 and a second edge 140, the first edge 130 and the second edge 140 extend along the axial direction Z, and the first edge 130 and the second edge 140 are welded together, so that the structure of the terminal is more stable and the terminal is not easy to crack. Further, the terminal includes a plurality of welding points 150, the plurality of welding points 150 are located at the connection between the first edge 130 and the second edge 140, and the plurality of welding points 150 are arranged along the axial direction Z, so that the terminal has sufficient structural strength and high welding efficiency.
