The fixing portion 12 has a rectangular planar shape for being connected to the circuit board ❹7〇〇. The fastening portion fixing portion 12 includes a first end 122 and an opposite second end 124. The positioning portion 14 is formed by the first end 122 of the fixing portion fixing portion 12 extending perpendicularly to the opposite direction of the circuit board 700 toward the fixing portion u. The ballistic portion 16 is formed by extending from the middle of the end portion of the positioning portion ,. One end of the ballistic portion 16 opposite to the positioning portion 14 extends perpendicularly to the fixed portion 10 and extends a bulletproof portion 162. The bulletproof portion 162 and the fixing portion 12 Roughly parallel. It will be understood that the position of the ballistic portion 16 is not limited to the portion of the end of the positioning portion 14 but may be any position at the end of the positioning portion 14. The elastic section 2G includes a first bent portion 22 and a second bent portion %. The first bent portion 22 includes a first connecting portion 222 and a first elastic portion 224. The first connecting portion 222 is formed in a substantially arc shape, and the first connecting portion 222 is formed by an arc extending from the second end 124 of the fixing portion 12 toward the opposite side of the fixing portion 12 and the circuit board 7 . The first elastic portion * 224 is arcuately extended from the end of the first connecting portion 222 toward the positioning portion 14. The first elastic portion 224 is substantially parallel to the fixed portion 12. The second bent portion 24 includes a second connecting portion 242 , a second elastic portion 244 , and a third connecting portion 246 . The second connecting portion 242 is substantially arcuate and is formed by an arc extending from an end of the first elastic portion 224 in a direction opposite to the fixing portion 12. The second elastic portion 244 is curved at an end from the end of the second connecting portion 242 in a direction opposite to the positioning portion 14. The second elastic portion 244 is substantially parallel to the first elastic portion 224. The second connecting portion 246 extends from the end of the second elastic portion 2 toward the first elastic portion 22. The contact segment 30 includes a contact portion 32 and a first curved portion %. The contact portion 32 is extended from the third connecting portion 246 toward the positioning portion 14 and is parallel to the fixing portion. The first curved portion 34 extends from the end of the contact portion 32 toward the positioning portion 14. The connecting section 40 includes a connecting portion 42 and a second curved portion 44. The connecting portion 幻 is the end of the first-shaped portion 34 extending in a direction perpendicular to the fixing portion 12. The second curved portion 44 extends from the end portion 3G of the joint portion 42. The overpressure prevention section 50 includes a branch portion 54 (see Fig. 2), two guide portions %, and a guide groove 58. The overpressure prevention section 5〇 is formed by the end of the second curved portion 44 extending in the opposite direction to the connecting portion 42, and the overpressure preventing section 5 is located below the bulletproof portion 162 with a predetermined gap therebetween. The intermediate portion of the overpressure prevention section 50. The bend extends for a distance and then rises to the branch portion 54, and the support portion 54 is disposed opposite to the positioning portion w, leaving a gap between the two and parallel to each other. The section of the overpressure prevention section 5〇 located on both sides of the branch portion 54 is folded to extend the two guide portions % and the connection two guide portions % and the overpressure prevention section such as one of the 5 201101973: curved portions 55. The guide portion % protrudes from the outer side of the positioning portion 14, and the guide portion % and the positioning portion M4 are parallel to each other with a gap. A guiding groove ‘ 58 is formed between the two guiding portions for accommodating the bulletproof portion 16 . It will be understood that the guide portion 56 is not limited to two, and the provision of one guide portion 56 can also achieve the function of the guide. Referring to FIG. 3, when the elastic structure 100 is compressed and contracted, the elastic segment 20 is elastically deformed toward the fixing portion I2, and the contact portion integrally formed with the elastic portion 2〇, the connecting portion 40 and the over-pressure preventing portion 5〇 The displacement in the vertical direction toward the fixed portion 12 is fixed. In this process, since the positioning portion 54 is disposed between the supporting portion 54 and the guiding portion 56 in parallel with the two and spaced apart from each other, the clamping position 14 can limit the supporting portion 54 and the guiding portion 56 to be perpendicular to The offset occurs in the direction of the positioning portion 14. The abutting engagement of the two end walls 582 on both sides of the guide groove 58 with the ballistic portion 16 can limit the deviation of the guide groove 58 in the symmetrical direction of the two end walls 582. Therefore, the contact portion % integrally connected with the support portion 54, the guide portion 56, and the guide groove % is subjected to the deviation from the direction of the granular portion 14 and the direction of the two end walls 582 of the guide groove 58 during the movement. limit. During the compression of the shrapnel structure 100, the support portion 54 prevents plastic deformation of the shrapnel structure. Specifically, when the deformation occurs after the second stage 2, the support portion 54 is correspondingly displaced in the vertical direction of the fixing portion 12 toward the fixing portion 12, when the elastic portion 20 is not plastically deformed, When the deformation is always increased and to a certain extent, the top end of the support portion 54 will abut the fixing portion 12, so that the elastic portion 2〇 stops deforming, so that the elastic portion 2 can be prevented from being excessively deformed when the elastic structure is excessively pressed. The elastic section 20 is plastically deformed or even broken. Moreover, the bulletproof section 162 located at the top of the bulletproof portion 16 is used to prevent the shrapnel structure from energizing 6 201101973 = re-timing after pressing, and the _ bit is excessive to cause the face segment 3q and good; specifically, when the elastic segment 20 is subjected to condensation resetting, and the spring pressure Segment 2〇—= ==〇 also with the bullet inspection 2 exposure straight to the fixed part u direction back = t when the shrapnel structure 100 is compressed - the fixed elastic force, when ^ I set up the role, prevent The pressure section 5G often has a pop-up of its unpressed port.
