At first setting, the fresh tin adhered to the first side of the adhesive part overflows to the second side, and will not stick to the elastic area of the reflexed part, which affects the elasticity of the elastic arm. Retractable anti-climbing shrapnel. [Prior Art] In the Republic of China's new patent case No. 90217221, a type of "surface-adhered micro shrapnel" was unveiled in October. From the third figure in i, the case revealed a kind of shrapnel 2 that contains the -adhesive part 30. The -refolded portion 31, the -elastic arm portion 32, the -contact portion μ, and the second retaining wall portion 25. The adhesive portion 30 has a first surface 3 on the road substrate for fresh tin contamination. . And a second opposite to the first surface = ^ HAI refolded portion 31 is extended from the-end of the length direction of the adhesive portion and folded to the second surface 301 of the adhesive portion, and the elastic arm portion 32 is 0 ^ At the end of the reflexed part 31 and at an angle to the adhesive part away from the adhesive part = diagonally extending in the direction of the side 301, the abutment part 33 is connected: one end of the raw arm part 32 is used to abut another member, and, Each static: 25 is respectively connected to the opposite sides of the adhesive portion% and adheres to it ;: Two = and L? Degrees extend away from the second surface, so that the bomb 32 and the abutment portion 33 can be located at the second retaining wall portion 25 — stop The wall part makes the adhesive part work day] 'The second to the second sticky solder cannot overflow the brother-surface 301 and sticks to the elastic arm part and affects the elastic arm part's elasticity. 4 M259447 First use, this case The second wall is used to prevent the solder from overflowing-surface 301, but there is room for further improvement in the ^ Μ η ^ s ^ of the shrapnel to prevent solder overflow. Therefore, how to construct a borrowed field The two sides of the elastic arm portion of the sheet form a narrow, narrow setting; the solder adhered to the first side of the adhesive portion overflows to the second: mismatch = the spring The flexible arm part affects the elastic effect of the elastic arm part: W inner shrinkable anti-climbing tin elastic sheet is a subject that can be improved. [New content] Therefore, the purpose of the new model is to provide a narrow set of narrowed sides on the two sides of the "provided shell", so that the second arm of the adhesive part: the fresh tin that accounts for the adhesive overflows to the second Surface, will not stick to the bullet and affect the elasticity of the elastic arm as an anti-climbing tin shrapnel. Floss thin type-stand, so the new type of retractable anti-climbing tin shrapnel of the spring arm, including a sticky :! 2 7 A reflexed part, an elastic arm part, and an abutment part. The reflexed part has a StQ and a spring contact area. The spring contact area provides the elastic arm I, and is free. The adhesive part has—and a circuit. The first dead surface of the substrate is welded and the second surface is used for the springback area of the reflexed part to spring back, which is characterized in that the width of the springback area in the springback area is made to be adjacent to the two ends and adhere to the elastic arm. The width of the part is narrow, and the width is narrower. It is formed in the inner edge of the elastic area on both sides-shrinking so that the first surface of the adhesive part is painted, and the tin overflows to the second surface. The sticking to the rebounding area of the reflexed portion affects the elasticity of the elastic arm. The function of the new model can provide an elastic sheet to make the first side of the adhesive portion The sticking solder of M259447 overflows to the second side, and will not stick to the springback area of the reflexed part, which will affect the elasticity of the elastic arm. [Embodiment] The foregoing and other technical contents and characteristics of the new model With regard to the effect, it will be clearly understood in the following detailed description with reference to the second embodiment of the figure. 〇 As shown in FIG. 1, FIG. 2 and FIG. The embodiment is formed by bending a sheet-like member with elastic material, and is soldered to a circuit substrate by surface adhesion, and can be elastically abutted to another member. The elastic piece 4 includes an adhesive portion 40 A reflexed portion 41, an elastic arm portion 42, and an abutment 43. The reflexed portion 41 has a bending area 41 and a springing area 411. The springing area 411 is to provide the elastic arm portion 42. It has elasticity, and the adhesive part 40 has a first surface 400 and a second surface for the reflexed αP springing area 411 to be soldered to the circuit substrate. The width of the resilient area 411 is made to be adjacent to the two ends: the width of the sticky portion 40 and the elastic arm portion 42 are wider. It is narrow, and the width of the first side of the spring-back area 411 is set to be inward-constricted by its wider opening, so that the solder adhered to the first surface 400 of the adhesive portion overflows to the second surface and does not stick. The elasticity of the elastic arm portion 42 is affected by the rebounding portion 41 of the reflexed portion. More specifically, the adhesive portion 40 further has a first surface 401, so that the first surface has a certain width. And length, the adhesive portion 400400 and a second 400 opposite to the first surface 400 are used to adhere to the solder, and are fixed on the circuit substrate by means of surface adhesion M259447. The reverse-folded part 41 is 逯 柱 你 私 # * is connected to one end of the sticky part 40 in the length extension direction, and a zigzag area 41 is formed in the direction opposite to the length of the sticky part 40. ^ ^ Continue to make arcs, only fold back into an elastic area 411. The elastic area 411 contacts the second surface 401 of the adhesive part 0, and it can also be spaced at a macro distance. In this embodiment, the bending region 410 of the reverse folding portion has a width equal to the width of the same width as μ 丄 3 Erxing Adhesive Portion 40, but the sound of 疋 5hai bouncing in the area 4 11 θ # ^ 幻The visibility w 疋 is narrower than the width w1 of the sticky portion 40, which means that it is also narrower than the width of the bending region 410.忒 The elastic arm portion 42 is connected to one end of the springback portion 411 of the reflexed portion and extends obliquely toward the direction away from the second surface 4 () at an angle with respect to the adhesive 胄 40. The width of the elastic arm portion 42 is 42G The width w of the elastic abutting region 411 is wider than the width of the adhesive portion 40 or the width of the bending region 410 adjacent to the adjacent folded portion. The elastic abutting region 411 makes the elastic arm portion 42 have an elastic effect. In the embodiment, the forming of the bending area “I0” of the reverse bending part, the elastic abutting area 411 and the elastic arm portion 42 is narrowed to a narrow width at the place where the bending area 41 is connected to the elastic abutting area 411. w Until the end connected to the elastic arm portion 42 returns to the same width 42 ° as the width W1 of the bending area 41 °, that is, the edges 411 ° and 4111 of both sides are formed into a contraction shape, and the abutment The portion 43 is connected to the other end of the elastic arm portion 42 and is substantially parallel to the adhesive portion 40 at a distance. The abutting portion 43 has the same width as the elastic arm portion 42. In application, the elastic piece 4 is moved by using an adsorption device to adsorb on the M259447 surface of the abutting portion 43, so that the first surface of the adhesive portion 40 can be adhered to the circuit substrate, and 2 after welding The abutment portion 43 of the adhesive elastic piece 4 can be used to contact the chip to be connected. The elastic contact of the abutment portion 43 with the elastic arm portion 42 relative to the reflexed portion abutment area 41 can provide elastic contact of the abutment portion 43. The effect is to avoid the phenomenon that tin overflow can cause the elastic arm portion 42 to lose its elasticity. This creation directly improves at least the width w of the rebound area 411 in the rebend portion to be narrower than the width wl of the bend area 410, that is, two The side edges WO, 4111 form an inward shrinking shape, as shown in Figs. 2 and 3. From the top and side views, the solder has overflowed from the first surface 400 of the adhesive portion 40 to the second surface 401. The elastic contact portion 411 of the arm portion 42 which is elastically in contact with the second surface 401 is not adhered to by solder, so the elastic effect of the elastic arm portion 42 is not affected at all. Figure 4 is another embodiment of the present invention. The above-mentioned inner narrow county 'extends at the end of the elastic area 41 i to the bending area of the reflexed portion ，, and the other end of the elastic area 411 extends to the elastic arm portion. The partial area 421 'of 42 is not affected by the solder in the rebound area 411 in the rebend portion, and the material can be saved. "..." As mentioned above, both the new model and the 9201 new patent case filed by the applicant previously can achieve the elastic effect of the elastic arm portion 42 not affected, and this case need not be the second retaining wall of the case. Department 25, which is less labor-intensive, and although there is a chance that the amount of solder exceeds, but the amount is not much, even if there are more than 40% of the spring area that will not be soldered to the case and the second side 4 8 M259447 The contact site, because of & & fragrance, can indeed achieve the stated effect. However, only the enhanced embodiment of the new model can not be used to limit the target range of the new model implementation, that is, the simplification made by the scope of the patent application and the content of the new specification. And modifications should still fall within the scope of this new patent. That ’s it, this new special effect change M259447 [Schematic description] Figure 1 疋 The perspective view of the retractable anti-climbing tin shrapnel of the new spring arm; Figure 2 is the drawing of the retractable anti-climbing shrapnel of the new spring arm; Figure 3 FIG. 4 is a schematic top view of the new i-type indented retractable anti-climbing tin shrapnel; FIG. 4 is a perspective view of the new type of inflated retractable anti-elastic tin bomb μ. η A three-dimensional schematic illustration of excessive tin in another embodiment M259447 [Description of the main symbols of the drawings] 4 Retractable anti-climbing tin shrapnel 40 Adhesive part 400 First surface 401 Second surface 41 Folding portion 410 Bending area 411 Reaching area 4110, 4111 Reaching area both sides 42 Elastic arm portion 420 Resilient arm portion width 421 Resilient arm portion area 43 Abutment portion W Reaching area width W1 Adhesive portion width 11
