Description of the new type: [Technical field to which the new type belongs] The new type relates to a conductive terminal, particularly a conductive terminal that establishes an electrical connection with a circuit board. [Previous technology] Referring to FIG. 1, conductive terminals are widely used in establishing electrical connections and electronic signal transmission. Electrical equipment needs to achieve the purpose of connection through a plurality of conductive terminals, as shown in the conductive terminal i in FIG. Is placed on a circuit board 2 (for convenience of explanation, only one conductive terminal is used as an example), the conductive terminal 1 has—the first end portion 11 and—is in the same extension direction as the first end portion 11 The second end portion 12 and the interference portion 13 are interposed between the first and second end portions Γ. Among them, the interference portion 13 includes two ellipses, singular slaves 131 ′, and the two elastically deformed sections 131 and the first and second loops, respectively; 14. Connected to the A and B positions and cooperate to form a space. When the assembly is completed, one of the conductive terminals 丨 the surface 2 of the circuit board 2 ^ 疋 颔 is at, 6X first end 丨 2 is exposed at the The other side 22 of the circuit board 2, and the interference: among them-inside the guide hole 23. Seek to save the circuit board 2 Refer to Figure 2, carry out the first end of the guide ... After the guide: 2 2 son 1 plugging operation, the hole is first ... restricted by the guide hole interference portion 13 before passing through Guide, the two elastic deformation sections 131 to 〜 deformation section ⑶ distance-for conductive terminals, 3 to compression and deformation occurs. 1 A conductive sprite 1 deforms, except for the two elastically deformed sections 131, the joints A and B at each joint of M267672 at 5h are stresses e,. Y ~ the point of concentration, and inevitably also occur here. The first end of the Deformation Society is next to the 19th ancient society 丄 I. Zhizi 1's younger brother ~ the end 11 or the younger one ... directly buckled by the connection A or B, so-come, the second and second ends 11, 12 are not A from . First, in the same direction of extension, the first 11M2 of the first 11M2 will be one to one — this will seriously affect the subsequent docking operations. Pre-formed 23 holes on the circuit board 2; ^ is not the same, but the 3 holes of the conductive terminal 丨 the force of the relocation of the sister industry makes the deformation early-the size 'causes the insertion of mechanical waste into force— The influence of the different degrees of 18 degrees, how to take the change of the kneading machine and the problem of Fang Nanza, >. Moreover, the elastic deformation section 131 ° is made in a working system. It is particularly easy to form a small gap between the guide holes 23 of the elastic deformation section 131 ("the guide holes for metal vaporization: ® 2), so that the air can penetrate the gap and the connection effect is greatly reduced. The electrical properties between 131 and circuit board 2 [New content] Therefore, 'A new structure of the new type has been excessively opened', and A and F are provided to prevent conductive terminal junctions. Ν Technique to maintain a conductive terminal with ideal mating effect Circuit board This new type of conductive terminal with group I insertion stability is used to establish electrical contact with a circuit board. # -Electric surface-the second surface of the circuit board has a first surface, as opposed to the first- The wall of the guide hole on the second side is: connecting the first side and the hole from the first side recess. The conductive terminal includes a first end portion, a first guide ==, and an interference portion. Deng, the end is exposed at the first: Γ is exposed outside the first side, and the second side is outside, the interference part is locked in the guide hole, and M267672 has two elastic deformation sections, each of which The elastically deformed section connects the first end portion and the second end portion of the joint and collectively delimits A compressible gap is formed, and the relative distance between the two elastically deformed sections is larger than the inner diameter of the guide hole before being unstressed. Each elastically deformed section is further formed to prevent the elastically deformed section from being excessively deformed by compression and causing the first And anti-buckling bumps where buckling occurs at the two ends. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be described in the following detailed description of a preferred embodiment with reference to the drawings. It can be clearly shown. Referring to FIG. 3, a preferred embodiment of the novel conductive terminal 3 with assembly and insertion stability 疋 most of them are electrically connected to a printed circuit board 4 at a certain interval, and are subject to two terminal bases 5 5 and 5. For the purpose of explanation, only one conductive terminal 3 is drawn as an example in the following figures. The circuit board 4 has a first surface 41 and a second surface 42 opposite to the first surface 41 The majority of the printed circuit board via hole walls 43 connecting the first, second, and 42 recessed from the first surface 41, and the majority of the via holes 44 (Plated thrugh) defined by each of the via walls u. 〇le). On the other hand, in each of the guide holes The toroidal surface of 43 is coated with _ copper pig layer ^ and a tin foil layer 46 (shown in FIG. 5) in order from the outside to the inside. Each of the terminal blocks 5 and 5 ′ corresponds to the first of the circuit board 4 respectively. The first and second sides 41 and 42 are disposed on opposite sides of the circuit board 4. If each of the terminal blocks 5, 5 is cut in a direction perpendicular to one of the imaginary planes of the plane of the circuit board 4, each of the terminal blocks ^ ' The cross-section is almost the same. The mouth-shaped openings of the two terminal bases are opposite to each other. M267672 Each conductive terminal 3 includes: a first end portion 31, a second end portion 32, and an interference portion 33, the first The two ends 31, 32 have the same extension direction. Referring to FIG. 4, the interference portion 33 has two ends connected to the first end 31 and the second end 胄 32, and each has an outwardly opened fox shape to The two elastic deformation sections 331 are formed in a pair of oblongs, and one elastic deformation section 331 of each conductive terminal 3 cooperates to define a compressible gap 332. In addition, in the unstressed state, the relative distance between the two elastically deformed sections 331 is greater than the inner diameter of the guide hole 44. In addition, each of the elastic deformation sections 331-the inner side surface 334 forms a predetermined angle 0 in the middle section, and the predetermined angle Θ is preferably greater than 120 degrees. Each elastic deformation section 331 has a position where the predetermined angle θ is formed. A 2 buckling bump 333, the anti-buckling bumps 333 of the two elastic deformation sections 331 protrude toward the compressible gap 332, that is, the second buckling-resistant bumps 333 protrude toward each other. For ease of explanation, in the following description, only a conductive terminal 3 is used as an example. As shown in FIG. 3, the conductive terminal 3 is not inserted into the circuit board 4. The conductive terminal 3 is the first one using the circuit board 4. One side 41 corresponds to the first end 43. The second side 42 corresponds to the direction of the second end 32 and the guide hole 44 of the circuit board 4 is inserted. When the first end 31 has completely passed the The guide hole 44, and the person entering the guide hole 44 next is the interference portion 33. Referring to FIG. 5, when the interference portion 33 gradually passes through the hole guide material, the hole wall 43 exerts a pressing effect on each of the elastic deformation sections 331. As the book industry continues to advance, the elliptical elastic deformation ⑫ 331 bears The compressive force gradually increases from M267672, and all the elastic deformation sections 331 are deformed toward each other with the direction of the force of the guide hole wall 43. At the same time, the anti-buckling bumps 333 of the two elastic deformation sections 331 are gradually approaching. When the pressing force is continuously applied, the two anti-buckling bumps 333 will finally touch each other, so that the first end portion 31 of the conductive terminal 3 is exposed on the first surface 41 of the circuit board 4 and the second end portion ^ The interference portion 33 exposed on the second surface 42 'is inserted into the guide hole 44 of the circuit board * in a tight fit. After all the conductive terminals 3 have been inserted at the same time, the first ends 31 of all the conductive terminals 3 are threaded to one of the terminal blocks 5 to form an electrical connection with a plate-to-board connector (not shown in FIG. 5). All the conductive terminals 3 and the second end portion 32 of the conductive terminal 3 pass through the other terminal block 5 to form an electrical connection with a cable (not shown in FIG. 5). In the mouth-to-mouth technique, the joint between the two elastically deformed sections 131 and the first and second ends UI / 2 forms two stress concentration points A and B. Therefore, when each section 131 is forced, it deforms It tends to be directly at the stress concentration point ^ If the junction A and B of the second Mr. A are deformed, the first and second ends # 1 will be caused. Frustration, the two are no longer in the same direction of extension. , The new Yu-elastic deformation section 331 through the anti-buckling bump state curve bump 333 is set to add to four 'especially each anti-frustration Lu ⑽ "inner side 334 of the deformation section 331 facing each other ::: : Γ 广 ~ ...,-but suffered from the shrinkage of the pilot hole; the block 333 can withstand repeated pressure on average, can the first and second end portions 31, 3 32 still be maintained in the same extension direction, M267672 That is, no lateral offset is formed, thereby ensuring the accuracy of subsequent docking operations. In addition, changing the size of each of the anti-buckling bumps 333 < may determine the durability of the interference portion 33 to the guide hole wall 43, further It seems that if each anti-buckling bump 333 is smaller, it means that each anti-buckling bump 333 has a relatively large movable distance within the compressible gap 332, and thus can withstand a larger pressing force. It is not easy for the conductive terminal 3 to buckle and directly lead to the situation that it cannot be smoothly docked with the terminal base 5. On the other hand, the size of each anti-buckling bump 333 can be determined according to the inner position of the guide hole 44, that is, If the guide hole 44 formed on the circuit board 4 for the conductive terminal 3 to be inserted is small, the anti-buckling bump 3 33 is relatively small. As mentioned, under the premise of the small volume of the anti-buckling bumps 333, the moving distance of each anti-buckling bump 333 within the compressible gap 332 is increased, and of course it is more able to cushion the The compressive force of the via hole wall 43 can strengthen the resistance of the interference portion 33 of each conductive terminal 3 to the compressive force. It is worth noting that each of the elastically deformed sections 331 is strongly pressed, so each of the elastically deformed sections 311 is It is tightly pressed against the tin foil layer 46, that is, an air-tight effect can be effectively produced between the two, so that air cannot easily enter the gap between the two. In this way, each of the elastic deformation section 331 and the copper foil layer 45 and the tin foil The layer 46 is less likely to form oxidation, which greatly blocks the possible negative effects of oxidation on electrical conduction. Knowing the above, the new conductive terminal 3 with assembly and insertion stability forms an anti-frustration through each elastic deformation section 331 The curved bump 333, during the insertion of the interference portion 33 into the guide hole 44 of the circuit board 4, the wall 43 of the guide hole forms a pressing force on each of the elastic deformation sections 331 of the bomb 10, forcing each elastic deformation section M to deform. Until the second resistance frustrated convex The block 333 conflicts, ensuring that the pressure is evenly applied to the interference portion 33, and the first end portion 31 and the second end portion μ are located in the same extension direction without tilting, and the assembly and insertion of the conductive terminal 3 are stable. The performance has been improved, and the quality of the docking has been maintained, so the purpose of the new model can be achieved. However, the above are only the preferred embodiments of the new model. Otherwise, the scope of the implementation of the new model is limited, that is, Any simple equivalent changes and modifications made according to this new type of towel: the scope of the benefit and the description of the new type are still covered by the new patent.
