Description

electrical connector

【Technical field】

The utility model relates to an electrical connector, in particular to an electrical connector capable of ensuring that terminals are stably held on an insulating body.

【Background technique】

A common electrical connector includes an insulating body and conductive terminals. The insulating body is provided with a rectangular opening at a central position, and the opening forms a receiving space for accommodating butted electronic 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 channel, an elastic butt joint arm bent from the main body and extending out of the terminal channel, and a welding part extending from the side edge of the main body. When the conductive end is welded or subjected to external force, the main body may move, thereby driving the contact portion to deflect, making the installation of the conductive terminal unstable and the contact unreliable. And when the elastic butt arm is deformed by force, the main body may also be driven to move, resulting in unstable installation of the conductive terminal and unreliable contact.

Based on the above defects, it is indeed necessary to improve the existing electrical connectors.

The elastic arm 22 is formed by extending obliquely upward from the free ends of the two side arms 211 . A fixing portion 23 extending vertically downward is formed on the outer edge of the middle portion of the side arm 211 , and a clamping portion 24 extending into the receiving hole 11 is formed on the inner edge of the side arm 211 . The clamping portion 24 is used for clamping cables (not shown), and the clamping portion 24 includes a first clamping piece 241 and a second clamping piece 242, wherein the first clamping piece 241 extends from the side arm 211 Extending horizontally, the second clamping piece 242 is located below the first clamping piece 241 and forms an acute angle with the first clamping piece 241 . The elastic arm 22 is U-shaped corresponding to the main body 21 and is located above the main body 21. The elastic arm includes two extension arms 221 connected to the two side arms 211 and arranged at an acute angle and connected to the ends of the two extension arms 221. The contact arm 222 is provided with a contact portion 223 in the middle of the contact arm 222 to contact with a circuit board (not shown).

Please continue to refer to FIG. 2 , the fixing member 3 is formed by punching and bending a sheet metal, which is approximately U-shaped and includes a holding portion 31 , a positioning portion 32 and a connecting portion 33 connecting the holding portion 31 and the positioning portion 32 . Two sides of the holding portion 31 are provided with barbs 311 . The holding portion 31 and the positioning portion 32 are parallel to each other and perpendicular to the connecting portion 33 .

1 and 2, the conductive terminal 2 is assembled into the insulating body 1, the main body 21 is correspondingly accommodated in the receiving groove 12, the side arms 211 are accommodated in the grooves 121 on both sides, the connecting arm 212 is accommodated in the connecting groove 122, and the fixing portion 23 corresponds to Insert into the holding groove 14, and hold on the holding groove 14 with the help of the barbs provided thereon.
