A slit 28a is formed in the width direction in the second positive curved portion 28, and a first plate ridge portion 29A and a second plate spring portion 29B are formed on both sides of the slit 28a. The slit 28a is It is set at a position slightly off-center in the width direction of the second positive curved portion 28, so that the plate width of the first plate spring portion 29A and the plate width of the second plate spring portion 29B are different. The first plate spring portion 29A and the second plate The spring portion 29B extends slightly parallel to the second linear portion 27f of the anti-curved portion 27, and is formed to bend forward and obliquely downward by the apexes 29Aa and 29Ba. The front end side of the slit 28a is continuous to the slit 28a. A second opening portion 28b having a width wider than that of the slit 28a is formed. The width of the second opening portion 28b is larger than the width of the anti-curved portion 27 In addition, protruding portions 29Ab and 29Bb protruding inward are formed at the front end portions of the first leaf spring portion 29A and the second leaf spring portion 29B. When the terminal 20 is accommodated in the terminal accommodation hole 11, the first positive curved portion 26 The reverse bending portion 27 and the second forward bending portion 28 are located in the terminal receiving hole 11, and the apex 29Aa of the first leaf spring portion 29A and the apex 29Ba of the second leaf spring portion 29B protrude from the top surface 10d of the housing 10. The vertices 29Aa and 29Ba can be connected to the conductor portion of the battery B on the mobile phone side from above.

Then, the curved surfaces near the front ends of the first leaf spring portion 29A and the second leaf spring portion 29B are bent downward along the inner surface of the front wall of the housing 10, thereby causing the second forward bend M243809 portion 28 to also bend downward and the reverse bend portion 27 and a part of the first positive curved portion 26 also bend downward with the vicinity of the bending point of the first positive curved portion 26 as a center. Therefore, one end portion 27a of the anti-bend portion 27 and the other end portion 27b are brought into contact with each other by friction, so that the conductor portion of the battery B and the circuit board pcb are electrically connected to each other. In the contact between the one end portion 27a and the other end portion 27b, these slope surfaces contact each other and are short-circuited, thereby electrically connecting the paths between the two end portions 27a and 27L · of the anti-bend portion 27 by using a shorter path to shorten the terminal 20 The electrical path length, that is, shorten the length of the apex 29Aa, 29Ba contacted by the battery B to the circuit board connection leg 25 contacted by the circuit board PCB. Therefore, the conductor resistance value of the terminal 20 can be reduced. Since the slope surfaces of the two end portions 27a and 27b of the anti-curved portion 27 are brought into frictional contact with each other, the contact pressure is also increased. Therefore, the contact reliability when the terminals for shortening the electrical path length are in contact with each other can be improved. It can be suitably used as a power connector 1 for electrically connecting a circuit board PCB provided on the charger side and a battery B provided on the mobile phone side. In addition, each terminal 20 includes two forward curved portions 26 and 28 and one reverse curved portion 27 connecting the two forward curved portions 26 and 28, so the length of the spring can be extended, the durability of the terminal 20 can be improved, and the connector can be maintained relatively. Low height, and increase the travel of the vertices 29Aa, 29Ba (variation in the vertical direction). When the first leaf spring portion 29A and the second leaf spring portion 29B are bent downward, as shown in FIG. 6 (B), the reverse bending portion 27 is partially located at the first leaf spring portion 29A and the second leaf spring portion 29B. In the second opening portion 28b between the first plate spring portion 29A, the second plate spring portion 29B, and the anti-bend portion 27 can be prevented from interfering with each other. In addition, when the reverse bending portion 27 is bent downward by pressing the apexes 29Aa and 29Ba downward, a part of the reverse bending portion 27 is located in the first opening portion 24 of the base portion 21, and mutual interference between the reverse bending portion 27 and the base portion 21 can be avoided. . In addition, since the plate width of the first leaf spring portion 29A is different from the plate width of the second leaf spring portion 29B, the elastic coefficients of the first plate spring portions 29A and the second plate spring portion 29B are also different. , Can prevent battery B and peaks 29Aa, 29Ba from the most intense contact by 12 M243809 to instant damage. · &Quot; Ginseng Figs. 7 to 10 illustrate a second embodiment of the electrical connector of the present invention.

On the connection name 64, the terminal ^ can be restricted to be pressed to the foot and the general recess 62 is inserted on the foot: when it is on the circuit board, the movement of 璧 ^ is projected. In addition, the solder 70 is moved upward at the connection portion. It is also abutted on the base Π, which can limit i. In addition, the rear edge of the first positive curved portion 7 71 extends rearward 3 to make it thinner than the width of the base 71. The base and the inverse f-curved portion 74 are inclined diagonally in front of it. Bend up. And 4 74a is connected to the first forward curved portion 73 so that 14 M243809 is connected to the second forward curved portion 75. The reverse bending portion μ has a first arc portion 74c, which is bent from the front end of the first positive bending portion 73 to the same width as that of the first positive bending portion 73, and is slanted downward and forward first by one end portion 74a. , And then extend in a circular arc, facing forward and bending. The anti-curved portion 74 further includes: a first linear portion 74d linearly extending upward from an end portion of the first arc portion 74c; an end of the first linear portion 74d extending in a circular arc shape toward one side in a backward direction and one in a downward direction The curved first arc portion 74e and the second arc portion 74f extending linearly from the end portion of the second arc portion to one side and extending backward obliquely downward to the other end portion 74b. One end 74a and the other end 74b of the anti-curved portion 74 face each other on a slope surface. When viewed from the side, the second forward curved portion 75 is bent by the other end portion 74b of the reverse curved portion 74, and extends obliquely upwards in a manner parallel to the second linear portion 74f. As shown most suitably in FIG. 8 (C), the second forward curved portion 75 is formed by gradually widening the width of the other end portion 74b of the reverse curved portion 74. A slit 75a is formed in the widthwise direction in the second positive curved portion 75, and a first leaf spring portion 76A and a second leaf spring portion 76B are formed on both sides of the slit 75a. The slit 75a is provided at a position slightly offset from the center in the width direction of the second positive curved portion 75, so that the plate width of the first plate spring portion 76A is different from the plate width of the second plate spring portion 76B. The first leaf spring portion 76A and the second leaf spring portion 76B extend slightly parallel to the second linear portion 74f of the anti-bend portion 74, and are configured to bend obliquely downward and forward through the apexes 76Aa and 76Ba, respectively. The apexes 76Aa and 76Ba are located on top of the convex and curved surfaces so that the contact pressure with the battery can be increased. On the front end side of the slit 75a, a second opening portion 75b wider than the slit 75a is formed continuously to the slit 75a. In addition, front end portions 76Ab and 76Bb extending downward are formed at respective front end portions of the first and second leaf spring portions MA and 76B, as shown in FIG. 10, and the outer side walls of the front end portions 76Ab and 76Bb are shown in FIG. 8. (a) Projections 76Ac and 76Bc extending outward are formed as shown. When the terminal 70 is accommodated in the terminal accommodation hole 61, the first positive curved portion 73, the reverse 15-M243809 curved portion 74, and the 篦 -τ & a normal test curved portion 75 are located in the terminal accommodation hole 61, and the first leaf spring The point 76 "and the apex 76Ba of the second leaf spring portion 76B are formed by the shell 60-4 ... when the sub 70 is received in the terminal accommodation hole 61, it is reversely bent. The front face of the linear portion 74d is blocked by each The braking of the terminal receiving hole 61 is beneficial. It restricts the forward and backward movement of the bending portion 74, the second positive, the rear portion of the bending portion 75 catches the inclined brake surface M of each terminal receiving hole 61 to restrict the second positive bending # 75 moves backward. In addition, the protruding portions 76Ac and 76Bc of the terminal 70 enter the recessed portions 66 formed on the two side walls of each terminal receiving hole 61 to restrict the forward and rearward movement directions of the front end portions 76Ab and 76Bb. The apexes 76Aa and 76Ba of the terminal 70 can be connected to the conductor portion of the battery on the mobile phone side from above. _ When the battery B is not connected, as shown in FIG. 10, the first plate 76A and the second plate spring of each terminal 70 The portion 76B is in a free state, and the apexes 76Aa and 76Ba of these portions are substantially covered by the top of the casing 60 60d protrudes. In addition, one end 74a of the anti-curved portion 74 is kept separate from the other end 74b. When the battery is to be charged, the conductive portion of the battery is brought into contact with the apexes 76Aa and 76Ba of each terminal 70, and these apexes 76Aa and 76Ba are pushed downward. Then, the protruding portions 76Ac and 76Bc formed at the front end portion 76Ab of the first leaf spring portion 76A and the front end portion 76Bb of the second leaf spring portion 76B are moved downward in the recess portion 66 and face one side. Bending downwardly, the second forward bending portion 75 is also bent downward, and a portion of the reverse bending portion 74 and the first forward bending portion 73 is also bending downward. Therefore, one end 74a of one of the reverse bending portions 74 and other ends thereof are bent. 74b—Surface friction and surface contact make the battery's conductor and the circuit board electrically connected to each other. Here, the movement range of the protrusions 76Ac and 76Bc is limited to the recess 66, so even if it comes from the oblique rear and below (X in Fig. 10 (Direction) load is applied to the first and second leaf spring portions 76A and 76B, and one end portion 74a of the reverse bending portion 74 and the other end portion 74b can be kept in contact with each other. In addition, the second positive bending portion 75 is bent downward. Behind the second forward bend 75 The inclined stopper surface 68 of each terminal accommodating hole '61 rubs and restricts the second forward bending portion 75 from moving to the rear 16 M243809, so that one end portion 74 a of the reverse bending portion 74 and the other end portion 74 b can be more surely kept in contact. In the contact between the one end portion 74a and the other end portion 74b, these slope surfaces contact each other and are short-circuited, so that the path between the two end portions 74a and 74b of the anti-bend portion 74 is electrically connected by a shorter path, and the length of the terminal 70 is shortened. The electrical path length is to shorten the length from the apex 76Aa, 76Ba that the battery contacts to the circuit board connection leg 72 that the circuit board contacts. Therefore, the conductor resistance value of the terminal 70 can be reduced. In addition, since the slope surfaces of the two end portions 74a and 74b of the anti-curved portion 74 are brought into frictional contact with each other, the contact pressure is also increased, so that the contact reliability when the terminals for shortening the electrical path length are in contact with each other, Therefore, it can be suitably used as a power connector for electrically connecting a circuit board provided on a charger side and a battery provided on a mobile phone side. In addition, each terminal 70 includes two forward curved portions 73 and 75 and one reverse curved portion 74 connecting the two forward curved portions 73 and 75, so that the length of the spring can be extended, and the durability of the terminal 70 can be improved, so that the connector can be maintained relatively. The lower the height, the larger the strokes of the vertices 76Aa and 76Ba (the amount of change in the vertical direction). When the first leaf spring portion 76A and the second leaf spring portion 76B are bent downward, a part of the reverse bending portion 74 is located in the second opening portion 76b between the first leaf spring portion 76A and the second leaf spring portion 76β. Interference between the first leaf spring portion 76A and the second leaf spring portion 76B and the anti-bend portion 74 can be avoided. In addition, when the reverse bending portion 74 is bent downward by pressing the apexes 76Aa and 76Ba downward, a part of the reverse bending portion 74 is located in the first opening portion 77 of the base portion 71, and the mutual relationship between the reverse bending portion 74 and the base portion 71 can be avoided interference. In addition, since the plate width of the first leaf spring portion 76A and the plate width of the second leaf spring portion 7 are different, the elastic coefficients of the first leaf spring portions 76A and the second plate spring portion 76B are also the same. It can prevent the battery B from being damaged instantaneously when the contact with the peaks 76Aa and 76Ba is the most intense. The embodiment of the present invention has been described above, but the embodiment of the present invention is not limited to this, and various changes can be made. 17 M243809 For example, as long as it is an electrical connector capable of electrically connecting a circuit board and an opposite connection member to each other, it can also be applied to the electrical connection between the circuit board pcB provided on the charger side and the battery B provided on the mobile phone side. Uses other than connectors 丨. The first forward bends 26 and 73; the reverse bends 27 and 74; the second forward bends 28 and 75 and the first leaf springs 29A and 76A; the plates of the second leaf springs 29B and 76B can also be seen. The desired elastic coefficient needs to be changed appropriately. [New effect] As explained above, according to the electrical connector of this creation, since the terminal includes two forward bends and one reverse bend connecting the two forward bends, the length of the spring can be extended to increase the durability of the terminal. Sex. In addition, the terminals are formed by punching and bending a metal plate, and when contacting the terminals with the connection member, the slope surfaces of both ends of the anti-bend portion can be brought into contact with each other. Therefore, the terminals are used to shorten the length of the electrical path. When contacting each other, the contact reliability can be improved. Therefore, it can be suitably used as a power connector for electrically connecting a circuit board provided on a charger side and a battery provided on a mobile phone side.
