[0022] The following is for reference Figures 1 to 5 The grounding terminal 10 according to the embodiment will be described.

[0023] Referring to the accompanying drawings, the grounding terminal 10 includes a main body 11 and a crimping portion 12. For reference, the following description will focus on the vertical direction and the front-back / left-right direction, with the grounding terminal 10 inserted into the connection hole 1a as the reference.

[0024] The main body 11 includes: a latch 112 that is inserted into and fixed in a connection hole 1a formed on the connecting object (e.g., PCB) 1; and a lever 111 formed to enable the operator to grasp or apply force during rework.

[0025] like Figure 2 As shown, the latch 112 is formed by bending the main body 11 into a roughly U-shape. Furthermore, the latch 112 is formed by bending approximately perpendicularly at both ends of the main body 11 and is positioned opposite each other, with its ends forming free ends, thus possessing its own elasticity. Additionally, the latch 112 is formed to gradually open outwards towards the upper part. By forming the latch 112 as described above, when the grounding terminal 10 is inserted into the connection hole 1a, an elastic force can be applied to the inner peripheral edge of the connection hole 1a, thereby stably maintaining the engagement state. Furthermore, even if the size of the connection hole 1a is different, the latch 112 can be inserted into it and stably maintain the engagement state. Moreover, since a downwardly tapering inclined surface is formed along the direction of insertion into the connection hole 1a, the resistance is small when the grounding terminal 10 is inserted into the connection hole 1a, thus allowing for easy insertion.

[0026] A locking portion is formed on the outer side of the latch 112 to prevent the latch 112 from disengaging from the connection hole 1a.

[0027] For example, refer to Figure 3 The locking portion of the latch 112 can be a serrated groove 113, which forms a serrated protrusion and concavity structure on the entire outer surface of the latch 112. Furthermore, the protrusion and concavity direction of the serrated groove 113 is inclined in the opposite direction to the direction in which the latch 112 disengages from the connecting hole 1a.

[0028] According to this embodiment, when the grounding terminal 10 is inserted into the connection hole 1a, it can not only stably maintain the engagement state through the elastic force applied by the latch 112, but also prevent the latch 112 from disengaging from the connection hole 1a through the serrated groove 113. Furthermore, since the grounding terminal 10 has the serrated groove 113, it can be easily adapted to connection objects 1 with different thicknesses.

[0029] In addition to the aforementioned serrated groove 113, the locking portion of the latch 112 also includes, for example, the locking portion of the latch tongue 112. Figure 4 As shown, it can also be a locking latch 114. The locking latch 114 is formed by cutting a portion of the latch portion 112 and bending it outward, and at least one or more can be formed on each of the two sides of the latch portion 112.

[0030] Furthermore, the locking tongue 114 is formed to gradually open outward from the side of the tongue portion 112 towards the upper part in the direction of insertion into the connection hole 1a, thereby enabling the grounding terminal 10 to be inserted into the connection hole 1a by elasticity, and after being inserted into the connection hole 1a, it can be hooked around the periphery of the connection hole 1a to prevent it from falling out.

[0031] A lever 111 is formed at the upper end of the latch 112 and is bent to protrude outward. When rework is required, as the operator grasps the lever 111 or applies force inward, the distance between the lever 111 and the latch 112 decreases, allowing the latch 112 and the serrated groove 113 to separate from the connection hole 1a, thereby enabling the grounding terminal 10 to be easily removed from the connection hole 1a. Here, to facilitate the operator's gripping or application of force, the bent portion of the lever 111 can be formed with a predetermined thickness, and its outwardly bent portion can be flat or curved. Furthermore, the length of the bent portion of the lever 111 toward the inward direction of the grounding terminal 10 can be formed to be short enough that the grounding terminal 10 can be separated from the connection hole 1a when force is applied to the lever 111. For example, the lever 111 can be bent relative to the end of the latch 112 to form a roughly "U"-shaped structure, so that the bent end is approximately on the same plane as the latch 112. However, the shape of lever 111 is only an example, and its shape can take many different forms as long as it protrudes outward from the upper end of the latch 112 and is convenient for the operator to apply force.

[0032] When the grounding terminal 10 is inserted into the connection hole 1a, the lever 111 can prevent the grounding terminal 10 from being stuck in the connection hole 1a and from continuing to be inserted into the connection hole 1a. That is, the lever 111 can also serve as a stop to limit the depth of the grounding terminal 10 being inserted into the connection hole 1a.

[0033] The crimping portion 12 extends from the main body 11 and is integrally formed therein, and is connected to the wire (not shown). The crimping portion 12 is generally bent to form a "U"-shaped structure, and a wire is inserted inside it, and the core wire and insulation layer of the wire are pressed and fixed by crimping.

[0034] The two end portions 121 of the crimping portion 12 may be formed with steps 121a and 121b, or the lengths of the two end portions may be different from each other. For example, the end portions 121 of the crimping portion 12 may be formed with steps 121a and 121b, so that the lengths extending from the bent portion are different from each other. Furthermore, the crimping portion 12 may also be formed with a structure in which the two side steps 121a and 121b are staggered. With the crimping portion 12 having steps 121a and 121b as described above, such as... Figure 5As shown, when a wire (not shown) is inserted into it and crimped, the longer side of the steps 121a and 121b partially overlaps with the shorter side, thereby crimping the wire and forming a 2D crimping structure.

[0035] However, the shape of the pressing part 12 and the steps 121a and 121b is not limited to the form shown in the figure, but can be modified in various substantial ways.

[0036] According to this embodiment, the crimping part 12 has a groove or uneven structure formed on the inner side surface that is connected with the wire, and adopts a 2D crimping method, so it can be applied to more wires of different thicknesses or types.

[0037] According to this embodiment, the grounding terminal 10 has a latch portion 112 with a serrated groove 113 or a locking tongue 114 formed on its outer surface, thus it can be easily adapted to connection objects 1 with different thicknesses. Furthermore, due to the elastic force of the latch portion 112, the grounding terminal 10 can stably maintain its connection with the connection object 1, and the serrated groove 113 and the locking tongue 114 can effectively prevent it from detaching from the connection object 1. Additionally, the grounding terminal 10 is equipped with a lever 111, making rework easier. Moreover, since the crimping portion 12 of the grounding terminal 10 adopts a 2D crimping method, it can be easily adapted to wires of different thicknesses and types.

[0038] In summary, the embodiments have been described with reference to the limited accompanying drawings. Those skilled in the art can make various modifications and variations based on the description. For example, appropriate results can be obtained by performing the described techniques in a different order than the described methods, and / or by combining or integrating the described systems, structures, devices, circuits, and other constituent elements in a different manner than the described methods, or by replacing or substituting them with other constituent elements or equivalents.

[0039] Therefore, other embodiments, other implementations, and equivalents within the scope of the claims are all within the scope of the claims of this invention.
