Description

electrical connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector with elastic terminals.

【Background technique】

A conventional electrical connector for connecting an electro-acoustic component to a circuit board includes an insulating body and a pair of elastic conductive terminals fixed in the insulating body. The insulating body is provided with a rectangular opening at the central position, and the opening forms a receiving space for receiving the butted electro-acoustic components. A pair of symmetrical terminal grooves open upward are arranged on the insulating body around the opening, and the conductive terminals are accommodated in the terminal grooves. The conductive terminal includes a main body accommodated in the terminal groove and an elastic butt joint arm extending out of the terminal groove. When the electrical connector is installed on the circuit board, the circuit board will press the elastic butt arm of the terminal to move into the channel until it is fully accommodated in the terminal channel. Due to the long length of the elastic docking arm of the terminal, during the pressing down process, its middle part tends to bulge upwards and touch the circuit board, so that the contact point at the front end of the docking arm does not make good contact with the corresponding conductive sheet on the circuit board. Therefore, it is necessary to provide an electrical connector to solve the above problems.

【Detailed ways】

As shown in FIG. 1 and FIG. 2 , the electrical connector of the present invention includes an insulating body 1 and a pair of elastic conductive terminals 2 fixed in the insulating body. The insulating body 1 is rectangular, and includes a frame-shaped body portion 10 and a rectangular accommodating space 12 arranged in the center of the body portion 10 for accommodating electro-acoustic components. On the body part 10 around the accommodation space 12, a pair of upwardly open terminal grooves 11 are oppositely arranged. On the side walls 102 of the Two ends of the side wall 102 are respectively provided with openings 111 vertically penetrating the side wall, and protrusions 112 are provided in the openings 111 . The main body 10 further defines a pair of through holes 121 at diagonal positions of the receiving space 12 .

The elastic conductive terminal 2 is formed by stamping and bending a frame-shaped metal sheet, which includes an "n"-shaped main body 22 and an elastic arm 21. The elastic arm 21 is bent upward from one end of the main body 22 and extends between the main body 22 It is arranged at an acute angle, so the elastic arm 21 will move toward the main body portion 22 when subjected to an external force acting downward. The main body 22 is accommodated in the terminal channel 11 , and includes first and second extension arms 222 , 223 parallel to each other and a connecting portion 221 connecting the first and second extension arms. A locking piece 224 vertically extending downward is respectively provided on the outside of the first and second extension arms 222 , 223 , and a receiving hole 225 is formed on the locking piece 224 . The buckling piece 224 is accommodated in the opening 111 of the side wall 102 , and the receiving hole 225 thereof interferes with the protrusion 112 on the side wall to fix the terminal 2 in the terminal channel 11 . The inner side of the second extension arm 223 is bent to form a clamping portion 226 , which is accommodated in the through hole 121 of the main body portion 10 and used for connecting a cable (not shown) extending from the electro-acoustic element.

As shown in FIG. 2 and FIG. 3 , the elastic arm 21 includes first and second elastic arms 211 and 212 parallel to each other and a contact portion 213 connecting the first and second elastic arms. When the electrical connector is installed on the circuit board, the contact portion 213 overlaps with the circuit board. The first elastic arm 211 is bent to form a folding line 214 near the middle position, so that the first elastic arm 211 is not in the same plane, and it is divided into two sections 211a, 211b arranged at an obtuse angle, and the section 211b adjacent to the contact portion is away from Channel top surface 110 . The second elastic arm 212 is also provided in the same manner. In other embodiments, the two ends are arc-shaped transitions. The arcuate transition or fold line results in a bend between the two sections of the elastic arm that faces away from the top surface 110 of the channel.

The terminal 2 is accommodated in the terminal slot 11 , and the elastic arm 21 protrudes from the top surface 110 of the slot 11 . When the electrical connector is installed on the circuit board, the contact portion 213 of the elastic arm 21 will be pressed downwards and move toward the main body portion 22 until it is fully accommodated in the terminal channel 11 . Since the first and second elastic arms 211, 212 are respectively provided with bending parts away from the top surface 110, when the elastic arms are pressed to the horizontal position, the elastic arms will be close to the horizontal state, so there will be no upward protrusion ,As shown in Figure 4. That is to say, due to the existence of the bent portion 214 , the elastic arm of the terminal can be fully accommodated under the top surface 110 of the channel 11 , thereby ensuring good contact between the contact portion of the elastic conductive terminal and the corresponding conductive piece on the circuit board.
