Electrical connector

The present invention relates to an electrical connector, and more particularly to a universal serial bus interface electrical connector.

The Republic of China Patent Publication No. M432980 discloses a USB socket electrical connector including an insulative housing, a plurality of conductive terminals received in the insulative housing, a metal inner casing encased in the outer body of the insulating body, and a metal outer casing. The USB socket of the prior art is generally assembled after the metal inner casing and the metal outer casing are welded together, and then sleeved on the outer body of the insulating body, after which the metal inner casing is bent and the fixing wall abuts against the rear end surface of the insulating body. . In the above assembly process, the method of welding the metal inner shell and the metal outer shell first is time-consuming, and at the same time, the welding technology is more economical than the assembly cost, and is not conducive to mass production in actual production; The welding legs of the metal inner casing are bent and formed after the assembly is completed, and the problem that the bending is not precise or cannot be closely attached to the rear end surface of the insulating body is easy to occur.

Therefore, there is a need for an improved electrical connector to compensate for the above-discussed deficiencies in the prior art.

The purpose of the present invention is to provide an electrical connector, especially an electrical connector having a low-cost, short-duty operation and a double-shell structure for achieving a more stable mounting effect.

In order to achieve the above object, the present invention provides an electrical connector including an insulating body having a base, a plurality of conductive terminals received in the insulating body, a shielding shell covering the outside of the insulating body, and a metal casing outside the shielding case. The shielding housing includes oppositely disposed side walls, the side wall includes a first portion and a second portion, wherein the sidewall of the shielding housing further has a stamped and formed elastic fin, the one end of the fin and the second portion Connected and the fin forms an angle α with the first portion, the metal casing includes an upper wall and opposite side walls, the side wall of the metal casing has a stopping hole, and the fin protrudes into the stopping hole Abutting against the stop hole of the metal casing forms two first stopping points to limit the movement of the shielding shell relative to the metal in the direction in which the casing is docked.

Compared with the prior art, the present invention has the following effects: the blanking and tearing structure of the inner casing of the electrical connector can reduce the strength of the outer casing during assembly; meanwhile, there are two stopping points on both sides of the inner casing. Preventing the sway between the front and rear positions of the two shells can effectively improve the holding effect of the inner and outer shells. The simple assembly process also saves labor and manufacturing costs.

The side wall 52 is provided with a stopper hole 521 and a holding piece 522 extending downward from the side wall 52. The blocking hole 521 includes an elongated hole 5211 located above and a short hole 5212 communicating with the long hole 5211 and located below. The bottom surface 4323 of the blocking block 432 abuts against the bottom wall of the short hole 5212. The first stopping point 4311 and the second stopping point 4321 of the shielding shell 4 are respectively received in the long hole 5211 and the short hole 5212 to prevent relative movement of the shielding shell 4 and the metal casing 5. The holding piece 522 is fixed to a printed circuit board (not shown).

The insulative housing 1 is integrally formed with the conductive terminal 2 and the reinforcing plate 3, and the insulative housing 1 is inserted into the shielding case 4 from the front to the rear in the insertion direction, and the abutting portion 412 on the shielding case 4 abuts against the groove on the base 11. In the 111, the rearward force of the shielding shell 4 on the insulating body 1 is provided; the first fixing leg 433 on the shielding shell 4 is wrapped around the rear end of the base portion 11, and the clamping leg 413 is clamped to the base portion 11. At the top rear end, the protrusion 113 on the base 11 abuts against the end edge of the top wall 41 of the shielding case 4. The above cooperation provides a forward force of the shielding case 4 relative to the insulating body 1, thereby ensuring the shielding case. The body 4 and the insulative housing 1 are fixed to each other in the front-rear direction; the metal shell 5 is fitted on the shielding shell 4 from top to bottom, and the second fixing leg 53 on the metal shell 5 is shielded from the rear end of the shielding shell 4 Providing a forward force of the metal casing 5 relative to the shielding casing 4; the recessed portion 511 correspondingly recessed into the punching hole 411 of the shielding casing 4, ensuring that the metal casing 5 and the shielding casing 4 are in the front-rear direction Fixed to each other; the bottom of the second stop point 4321 on the side wall 43 of the shielding case 4 4323 corresponds to the short hole 5212 of the blocking hole 521 of the metal casing 5, and prevents the relative movement of the metal casing 5 and the shielding casing 4 in the up-and-down direction, and the fin 431 of the shielding casing 4 is also provided. The function of cushioning and damping reduces the force during assembly.
