New description: [New technical field] The present invention relates to an electrical connector, and more particularly to an electrical connector for connecting a power source. [Prior Art] Chinese Patent No. 200420116764 discloses a battery connector 6 for use in a portable electronic product in contact with a panel (not shown) for electrical connection. As shown in FIG. 1, the battery connector 6 includes an insulating body 60 and a plurality of terminals 61. The insulating body 60 is formed with a plurality of terminal receiving slots 62. The terminals 61 are received in the corresponding terminal receiving slots 62. The insulating body 60 has an upper surface 600 and a lower surface 601 opposite to the upper surface 600. The upper surface 600 and the lower surface 601 are formed with a front end surface 602 and Rear end face 603. Each of the terminal receiving grooves 62 defines an upper opening 620, a lower opening 621 and an insertion opening 622 on the upper surface 600, the lower surface 601 and the front end surface 602, respectively. The width of the upper opening 620 is slightly smaller than the width of the terminal receiving groove 62. A retaining groove 623 is defined in the inner wall of the terminal receiving groove 62 near the lower opening 621. Each of the terminals 61 includes a resilient contact arm 610, a base portion 611, a first bent portion 612 connecting the resilient contact arm 610 and the base portion 611, and a soldering portion 613 extending downward from the base portion 611. Specifically, the elastic contact arm 610 is sequentially provided with a second bending portion 614 and a third bending portion 615, wherein a contact portion 616 protrudes from the top of the third bending portion 615. In addition, the elastic contact arm 61 has a pair of buckles 617 extending to the sides, and two fixed wings 618 extend from both sides of the base 611. After the terminal 61 is assembled into the terminal receiving groove 62, the contact portion 616 protrudes from the upper opening M316533. 620, and the entire elastic contact arm 610 is relatively positioned in the terminal receiving groove 62 by the two latching ears 617, and does not pop out. The fixing wings 618 on both sides of the base portion 611 of the terminal 61 are received in the corresponding holding grooves 623, and the terminal 61 is fixed in the terminal receiving groove 62 by an interference fit with the groove wall of the holding groove 623. The soldering portion 613 of the terminal 61 extends through the lower opening 621 of the terminal receiving groove 62 and can be further soldered to a circuit board. When the interface is docked with the panel, the contact portion is correspondingly displaced downward with the pushing of the panel, resulting in an initial position of contact between the contact portion of the electrical connector and the gold finger on the panel. The final position is relatively large. The size of the gold finger on the battery board is large to meet the needs of accurate docking and stable connection, and it is difficult to adapt to the trend of miniaturization of the product; otherwise, the contact portion of the terminal is likely to slip out of the gold finger and the contact is poor. Therefore, the existing electrical connection benefits of this type still need further improvement. [New content] The present invention mainly provides an electrical connector capable of reducing the relative displacement between the initial position of the interface portion and the final docking position of the interface with the gold finger on the panel, correspondingly The size of the gold finger on the panel does not need to be too large to ensure an accurate and stable electrical connection. The present invention provides the following technical solutions: a battery connector comprising an insulative housing having two terminal receiving slots and a plurality of terminals received in respective terminals. The insulative housing has a front end surface for abutting, and each of the terminals forms a front opening on the front end surface. Each of the terminals has a f, a contact portion of the elastic arm connected to the base end and a contact portion extending from the front opening σ, and a welded portion connected to the other end of the base. The insulating body forms a limiting portion above the opening M316533 to limit the elastic arm of the terminal during the crimping action. In an embodiment, the elastic arm of each of the terminals further includes a first U-shaped portion and a second shaped portion extending from the base, and each of the U-shaped portions includes a first leg and a second leg. An opening of a U-shaped portion faces the base, and an opening of the second U-shaped portion faces a front end surface of the insulative housing. The first U-shaped portion is composed of a first leg extending upward from one end of the base portion and a second leg extending downward from the first leg; the first leg of the first portion extends The second leg end of the first U-shaped portion, the top of the second U-shaped portion is a contact portion, and the second leg of the second domed portion extends from the contact portion into the terminal receiving groove. The second leg of the second U-shaped portion is located above the first leg and faces the limiting portion. The terminal receiving groove is formed with an upper blocking wall at the front opening, and the upper blocking wall constitutes the limiting portion. The free end of the elastic arm of the rafter is formed with a fastening portion; and the two side walls of the terminal receiving groove are correspondingly recessed with a displacement groove, and the fastening portion is received in the displacement groove. The displacement groove has an upper stop portion and a lower stop portion, and the buckle portion is limited between the upper and lower stops. The two lower stops of the displacement groove form a fitting opening through the front end surface, and the fastening portion is assembled by the fitting opening. The raft receiving groove is formed with an upper wall at the front opening, and two side walls are respectively formed from the two sides of the upper wall to the upper side of the assembly opening, and the fastening portion abuts the sides Block the wall. A rear end portion is disposed at a rear end of the terminal receiving groove, and the rear stop portion resists the first leg supporting the first u-shaped portion in an elastic deformation of the end M316533. A plurality of holding portions are disposed on both sides of the base of the terminals, and a lower portion of each of the terminal receiving grooves is formed with a holding groove on both sides of each front opening; the holding portion is received in the corresponding holding groove. The welded portion is bent downward from the end of the base and then horizontally extended. Compared with the existing battery connector, the contact portion of the terminal does not always move up because of the limit of the limiting portion during the docking process, but a back shift occurs. Therefore, the displacement between the initial position and the final docking position of the contact portion is small, and the size of the gold finger on the corresponding required battery board is small; the utility model has the advantages of reducing production cost, stable electrical connection, and being suitable for miniaturization of the product. [Embodiment] For a better understanding of the spirit of the present invention, a further embodiment of the present invention will be further described below. As shown in Fig. 2, the electrical connector 1 according to a preferred embodiment of the present invention can be placed in a portable electronic product for connecting an inserted independent panel to provide power to the entire product. The electrical connector 丨 includes an insulative housing 2 and a plurality of terminals 3 disposed in the insulative housing 2 . 3 and 4, the insulative housing 2 has a substantially rectangular parallelepiped shape, and a plurality of terminal receiving slots 4 for receiving the corresponding terminals 3 are arranged side by side along the length thereof. The surface of the insulating body 2 facing the battery panel is a front end surface 2〇, and the front end surface 21 is opposite to the front end surface 2〇, and the front end surface 2〇 and the rear end surface 21 are connected to form an upper surface 22 and a lower surface 23. Each of the terminal receiving grooves 4 extends through the front end surface 2 〇 to the rear end surface 21 ′ of the insulative housing 2 to form a front opening 4 〇 and a rear opening 41 , respectively, and a lower opening 42 is formed at the front end of the lower surface 23 . Each of the terminal receiving grooves 4 forms a rear stop portion 25 of M316533 below the rear opening 41. A displacement groove 43 extending from the front to the rear is formed on each of the inner side walls of each of the terminal receiving grooves 4, and the two displacement grooves 43 respectively form upper and lower stops 43〇, 43 on opposite side walls thereof. . Further, the lower portion of the two displacement grooves 43 forms a fitting port % on the front end face 2'. The terminal receiving groove 4 defines an upper retaining wall at the opening 40, and the upper retaining wall defines a limiting portion 4 and extends downwardly from the two sides of the upper retaining wall to the upper side of the mounting opening 26 to form two side stops. The wall 261 has opposite holding grooves 44 formed on both sides of the lower end opening 42 of the lower end of the terminal receiving groove 4. As shown in Fig. 4, each terminal 3 has a resilient arm 3''', a contact portion 31, a base portion 32, and a solder portion 33. The elastic arm 3 has a first u-shaped portion 3〇〇 and a second u-shaped portion 301, and the shaped portions 30〇, 3〇1 respectively have a first leg 3〇〇a, 301a and a second leg 3〇〇b, 3〇lb. The first ridge portion 3 〇〇 is open and the 苐 leg extends from the base portion 32; the opening direction of the second u-shaped ridge faces the front end surface of the insulating body, the second. The first leg 3〇1a of the shape 301 is bent forward from the second leg end of the first u-shaped portion 3〇〇 to form a convex arc, and the second leg 3〇1b extends The first leg 301a is above and facing the limiting portion 24, and the free end thereof forms a lever-shaped latching portion 34. The contact portion 31 is formed on the first u-shaped portion 301; The welded portion 33 extends from the base portion 32 and the other end of the elastic arm 30 is slightly folded downward and then horizontally extended. Further, in order to further hold the terminal 3 in the terminal receiving groove 4, a plurality of holding portions 32 such as barbs are provided on both sides of the base portion 32. 3, 4, 5 ' Align the latching portion 34 at the end of the elastic arm 30 of the terminal 3 with the mounting opening 26, the base portion 32 is aligned with the retaining groove 44, and the front end is assembled into the terminal to receive the 4 slot 4, while With the advancement of the terminal 3 in the terminal receiving groove 4. The holding portions 320 on both sides of the base M316533 - 32 interfere with the groove walls of the corresponding holding grooves 44, and the terminals 3 are relatively held. The latching portion 34 is elastically restored in the displacement groove 43 and is biased forwardly and is resisted by the side retaining wall 261 on both sides of the front opening 40. The elastic arm 30 of the terminal is generally designed. It has an initial pre-elastic deformation, a so-called pre-pressure action. The displacement groove 43 has an upper stopper portion 43 〇 and a lower stopper portion 43 1. The latching portion 34 is restrained between the upper and lower stopper portions 430 and 431, and the first U-shaped portion 301 is permanently deformed by the restriction force. The contact portion 31 of the terminal 3 protrudes beyond the front opening 40 of the terminal receiving groove 4, and the welded portion 33 extends at the lower opening Φ 42 . As shown in Fig. 6, when the battery connector 1 is mated with a battery board e, the battery board E pushes the contact portion 31 of each terminal 3 to elastically deform the elastic arm 30. At the initial stage E1 of the butt joint, the elastic arm 30 elastically deforms inwardly under the action of an external force, thereby causing the position of the contact portion 31 to be initially moved up until the second leg 301b of the second U-shaped portion 301 of the elastic arm 3A abuts. The limiting portion 24 of the insulating body 2, such as E2. Further pressing of the battery panel, the contact portion 31 of each terminal 3 is moved downward by the stop of the limiting portion 24, and after the force is stopped, the respective terminals 3 are slightly rebounded by the elasticity of the elastic arm 30, and finally Reach a relatively balanced state, such as E3. The rear stopper portion 25 resists the first leg 300a supporting the first u-shaped portion 300 in the elastic deformation of the terminal 3, so that the first leg 300a does not protrude from the rear opening 41 and can reinforce the elastic force of the terminal. As can be seen from FIG. 6, the displacement hi between the initial position E1 and the final position E3 of the contact portion 31 is much smaller than a displacement h2 of E1 to E2 during the docking process, and it is easy to see that the infinite portion 24 is The stop of the contact portion 31 will continue to rise upward. Therefore, the setting of the limiting portion 24 greatly reduces the displacement of the contact portion 3丨 between the initial position and the final position M316533, and the size of the gold finger on the corresponding panel E is also greatly reduced. Therefore, the present invention has the disadvantages of being accurate and stable at the lower cost than the existing battery connector, which is suitable for miniaturization of the product. The technical content and technical features of the present invention have been disclosed as above, but those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention. Therefore, the scope of protection of the present invention is not limited to the contents disclosed in the embodiments, but should include various alternatives and modifications that do not depart from the present invention and are covered by the present application.
