The present invention relates to an electrical connection device, and more particularly to a flat electrical connector.

A conventional electrical connector includes an insulative housing, a conductive terminal mounted on the insulative housing, and a metal housing that shields the conductive terminal. First, each component needs to be formed, and after the molding, the conductive terminal is inserted into the insulative body from the front to the rear or from the back to the front. The insulating body and the metal casing are fixed, and the manufacturing process is complicated, and more steps are required to realize assembly.

Therefore, it is necessary to design an electrical connector to overcome the aforementioned deficiencies.

The purpose of the present invention is to provide an electrical connector which is simple in structure and convenient in assembly.

In order to achieve the foregoing objectives, the technical solution of the present invention is: an electrical connector defining a front and rear direction, including a circuit board and a seat body, the base body including an insulative housing and a shielding housing, the circuit board including the first connecting component a mating end and a connecting end connected to the second connecting component, wherein the mating end and the connecting end are electrically connected by a conductive line provided on the circuit board, wherein the mating end protrudes forwardly from the shielding shell, and the connecting end protrudes rearward from the shielding shell The circuit board is provided with a notch on both sides of the conductive line, and the shielding shell is correspondingly provided with an elastic arm that abuts against the notch.

Compared with the prior art, the electrical connector of the present invention is simple to manufacture and easy to assemble.

The first figure is a perspective view of the present electrical connector; the second figure is an exploded view of the first figure; the third figure is an exploded view of the first figure; and the fourth figure is a flexible circuit board of another embodiment of the present creation A perspective view of the reinforcing plate.

As shown in the first and second figures, the electrical connector 100 of the present invention includes an insulative housing 10, a circuit board 20, and a shielding housing 30. The insulative housing 10 and the shielding housing 30 are injection molded, and the two enclose a receiving circuit board. 20 housing cavity 101.

Referring to the second figure, the circuit board 20 is flat, and defines a longitudinally long front end as a butt end 21 for mating with a mating connector (not shown), and a longitudinally long rear end is defined as a connecting end 22, which can be connected to the line. Cables (not shown, which may be flat cables or twisted pairs) are connected. The circuit board 20 is respectively provided with a plurality of contact pads 23 at the front and the rear ends. The contact pads 23 include a first contact pad 231 at the mating end 21 and a second contact pad 232 at the connecting end 22. The first contact pad 231 can directly The conductive terminals of the butt connection are in contact, and the second contact pads 232 are fixed to the cable by soldering or the like. The first contact pad 231 and the second contact pad 232 are connected by a conductive line 24 provided on the circuit board (only a portion is shown by a broken line), thus achieving electrical connection between the cable and the mating connector.

Referring to the second and third figures, the butt end 21 of the circuit board is slightly narrower than the connecting end 22, and the two sides of the circuit board are provided with notches 25, and the notches are substantially located at an intermediate position in the front-rear direction of the circuit board. The square projection on the front side of the notch is defined as the ear portion 26. The insulative housing 10 is formed by injection molding the insulative housing 10 so that the insulative housing is integrated with the shielding housing, and the two can be defined as the housing 40. The shielding housing 30 includes an upper wall 301, a lower wall 302 and two side walls 303 connected to each other. The insulating body 10 is formed with a bottom wall 102 and two side walls 103. The lower wall 302 of the shielding shell 30 is located below the insulating body, and both ends of the shielding shell 30 are embedded in the side walls 103 of the insulating body.

A pair of elastic arms are stamped downward from the upper wall 301, and the elastic arms extend to both sides and are located inside the side walls 103 of the insulating body. The elastic arm 31 includes a blocking portion 311 and a guiding portion 312 extending rearward from the blocking portion. The guiding portion 312 can guide the ear portion 26 of the circuit board to move rearward until the resisting portion abuts against the notch 25. At this point, the shield housing just covers the conductive traces 24 on the board. The ear defines a front end face 262 and a rear end face 261. The rear end face can also be referred to as the inner surface of the notch, so that the abutment portion can also be said to abut against the rear end face 261 of the ear. A pair of blocking portions 11 are provided at the front end of the insulating body, and the front end surface 262 of the ear portion abuts against the blocking portion 11. Thus, the ear portion 26 is restricted in the front-rear direction, that is, the circuit board is restricted in the front-rear direction, and when mated with the mating connector, the circuit board does not move back and forth due to the action of the insertion force, ensuring electrical connection. Stable.

Referring to the fourth embodiment, in another preferred embodiment, the circuit board is a flexible circuit board 20', but the flexible circuit board is directly inserted into the receiving cavity formed by the insulating body and the shielding shell during installation, so the flexible circuit board 20' itself has a small strength, so a layer of reinforcing plate 21' is attached to the bottom surface of the circuit board to achieve the purpose of increasing strength.

Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the present invention, and it is still possible for those skilled in the art to make equivalent substitutions of the modifiers and retouchings without departing from the spirit and scope of the present invention. This is the scope of patent protection for this creation.
