New description: [New technical field] This creation is about an electrical connector, especially for an electrical connector that can stabilize electrical contact terminals. [Prior Art] With consumer electronics constantly moving towards light In thin, short, and small directions, for example, in mobile devices such as mobile phones and PDAs and digital cameras, the miniaturization and the sturdy design of mobile devices require connectors to be downsized and have a thin profile ( Low prof i le) features, in addition, the versatility of mobile communication development, therefore, the density of electronic components mounted on the circuit board increases, it requires the correspondingly arranged plug and socket terminals, thus continuously reducing the arrangement between the terminals The density of the plug and the height of the socket, while ensuring that the terminal can maintain a stable pull-out retention in the confined space has become the direction of current research in the industry. As disclosed in Chinese Patent Publication No. 1237662, a board-to-board female connector structure is disclosed. The terminal is stamped and bent by a metal sheet, and is composed of a leaf spring portion, a fitting portion and an end portion, wherein assembly The first arm, the second arm and the second bending portion are included on the upper part, and the contact portion is included in the upper part of the socket body; the terminal is fixed in the preset hole of the socket body from the top to the bottom, and then passed through the leaf spring The contact apex and the second bend together form a double contact to make contact with the plug connector for 3 M419276 telecom transmission. However, the terminal is only interfered in the predetermined hole of the insulating body by the protrusion on the first arm during the assembly process, and is not fixed on the second arm, in this case, due to all the terminals. The protrusions on the first arm are all on the same straight line and are arranged in a high density in the confined socket body space, so the size of the protrusion on each terminal is limited, and the pull-out force of the single terminal is very limited. When the connector is connected to the male connector multiple times, it is easy to loosen the terminal, which causes serious instability of the electrical characteristics. Moreover, during the SMT process, the terminal is easily loosened due to the influence of high temperature welding. Causes poor soldering, resulting in unstable contact. [New content] The structure of the conventional electrical connector is not reliable for the assembly of the terminal, which causes the electrical connector to be prone to complaints. The present invention provides an electrical connector comprising an insulative housing and a plurality of terminals, wherein the insulative housing is provided with a plurality of receiving slots, each of which is formed by a side wall and a recessed structure formed by a stop portion connected to one of the side walls.

The second insulator 22 has a base portion 221, and the base portion 221 is provided to be embedded with the mating connector 4, and a plurality of accommodating grooves 222 are formed in each of the two sides of the base portion 221 in the longitudinal direction of the base portion 221. The accommodating grooves 222 extend through the base portion 221. In the upper surface, each of the accommodating grooves 222 is formed by a side wall 223 of the base portion 221 and a recessed structure formed by the stopper portion 224 connected to the side wall 223. A groove 226 corresponding to the accommodating groove 222 is provided on the bottom portion of both sides of the outer edge portion 225 on both sides of the connecting base 221, and a bottom portion of the outer edge portion 225 is provided at the inner end of each groove 226. In the hollow portion 227, the hollow portion 227 may receive a small amount of deformation displacement at the bottom of the terminal 3 when the terminal 3 is stressed, so as to disperse the force of the terminal 3 and prevent stress from being concentrated on the terminal 3. In this embodiment, the second insulator 22 is in contact with the main body 211 and the long arm 213 of the first insulator 21 by the outer edge portion 225, and the second insulator 22 is fixed to the first insulator 21 by ultrasonic wave processing. In one. The plurality of terminals 3 include a welded portion 31 integrally formed by metal stamping, a fixing portion 32, and an elastic portion 33. The fixing portion 32 is located between the welded portion 31 and the elastic portion 33, wherein the fixing portion 32 is insert-molded on the insulating body 2. The elastic portion 33 extends from the fixing portion 32 along the accommodating groove 222, and the welded portion 31 extends from the fixing portion 32 toward the outer side of the insulating body 2. The fixing portion 32 is composed of a first fixing arm 321, a second fixing arm 322, and a connecting arm 323 that connects the first fixing arm 321 and the second fixing arm 322. 6 M419276 The elastic portion 33 extends from the end of the second fixing arm 322, and includes a horizontal arm 331 at the bottom of the groove 226, a contact arm 332 connecting the horizontal arm 331 and extending upward, and a connecting contact arm 332. The buffer arm 333 extending from the side wall 223 and the stopping portion 224, the buffer arm 333 is disposed to abut against the first abutting portion 334 and the second abutting portion 335 of the side wall 223 and the stopping portion 224 respectively to form a The convex arc structure, wherein the contact arm 332, the horizontal arm 331 and the second fixing arm 322 are in a "U" shape to form a contact space with the mating connector 4, and continue to extend from the rear end of the contact arm 332. A buffer arm 333 having a convex circular arc structure is formed. When the butt connector 4 is butted into the elastic portion 33 of the terminal 3, the elastic portion 33 is displaced by the force, and since the force includes the downward force and the forward force, the buffer arm 333 of the elastic portion 33 at this time. The first abutting portion 334 can be forwardly abutted against the side wall 223 ′. The second abutting portion 335 can be pressed down against the stopping portion 224 to prevent the contact arm 332 from being excessively deformed by the force, and The contact arm 332 is provided with sufficient elastic restoring force, and also drives the horizontal arm 331 toward the hollow portion 227. The buffer space 336 and the hollow portion 227 formed between the contact arm 332 and the buffer arm 333 located in the receiving groove 222 are provided. The structure is such that the movable space provided to the elastic portion 33 with sufficient elastic deformation 'avoids stress concentrated on the elastic portion 33 causes the elastic portion 33 to lose elasticity. In addition, in order to make the docking connector 4 easier to apply to the contact arm 332, the angle between the horizontal arm 331 and the contact arm 332 is between 70 degrees and 90 degrees, and the blocking portion 2 is 7 M419276 is adjacent to the junction of the contact arm 332 and the horizontal arm 331 to obtain a better effect. In summary, the electrical connector of the present invention completely covers and fixes the fixing portion of the terminal to the insulating body by insert molding, so that the effect of optimally holding the terminal can be obtained, so as to solve the conventional interference assembly. The terminals that are easily caused by the terminals are loose and the electrical characteristics are unstable.
