In a preferred embodiment, the electrical connector plug and its components are intended for use with flexible cables. The flexible cable mentioned here preferably refers to a flexible flat cable (FFC/FPC, Flexible Flat Cable/Flexible Printed Circuit). However, in other different embodiments, the flexible cable can also be an electric wire, a mini-coaxial wire, or other flat cables. In addition, the flexible cable is preferably disposed on the bearing seat of the electrical connector plug in an adhesive manner. However, in other different embodiments, the flexible cable can also be positioned on the bearing base with an iron shell with convex points on both sides, or positioned on the bearing base by piercing the iron shell together with the contact part, and Or directly set wings on both sides of the flexible cable, and position them on the positioning elastic arm. Below promptly cooperates accompanying drawing, further illustrate the specific embodiment of the present invention and steps thereof:

As shown in FIG. 2 , the electrical connector plug 100 of the present invention is used in conjunction with a flexible cable 700 . The electrical connector plug 100 includes an electrical connector plug body 110 having a bearing seat 120 and two positioning elastic arms 130 . In the embodiment shown in FIG. 2 , the electrical connector plug body 110 is preferably made of insulating materials such as plastic or synthetic resin. The positioning elastic arm 130 is preferably disposed on both sides of the bearing seat 120 , and the positioning elastic arm 130 and the bearing seat 120 are preferably integrally formed. However, in other different embodiments, the positioning elastic arm 130 can also be connected with the bearing seat 120 to form a secondary process. One end of the positioning elastic arm 130 protrudes from the bearing base 120 , and the other end has a non-connecting portion 140 between the bearing base 120 . In other words, the protruding portion of the positioning elastic arm 130 is mainly designed so that when the positioning elastic arm 130 is pressed, the positioning elastic arm 130 can slightly rotate around the bearing seat 120 . In addition, an extension portion 132 extends from the outer end of the positioning elastic arm 130 , and a hook portion 134 is formed on an inner wall edge of the extension portion 132 .

In this embodiment, one surface of the bearing seat 120 preferably has an inclined surface 122 , and the inclined surface 122 is inclined toward the hook portion 134 . However, in other different embodiments, the two surfaces of the bearing seat 120 can also be arranged as two parallel planes. In addition, there is preferably a protruding portion 124 at the edge of the inclined surface 122 for setting and limiting the flexible cable 700 . The positioning elastic arm 130 has a gap 136 formed opposite to the other end of the hook portion 134 . In other words, the gap 136 is formed in a direction protruding from the bearing seat 120 and extends to a certain length. However, in the embodiment shown in FIG. 3 , the positioning elastic arm 130 can also be a rigid force applying arm 138 in one piece. Returning to Fig. 2, the gap 136 further separates the positioning elastic arm 130 from the force applying arm 138 and the blocking arm 142, and the blocking arm 142 is used for the force applying arm 138 to stop, so the force applying arm 138 can rotate slightly and stop on the blocking arm 142 . Wherein the force applying arm 138 also has a curved surface 148 which is easy to apply force on the surface.

Fig. 4 is an exploded view of another preferred embodiment of the present invention. This embodiment provides an electrical connector assembly, including an electrical connector plug 100 and an electrical connector receptacle 200 . In other words, it is a structure in which the electrical connector plug 100 and the correspondingly connected electrical connector receptacle 200 form an electrical connector assembly. The structure of the electrical connector plug 100 is the same as that described above, and will not be repeated here. The electrical connector socket 200 has a socket body 210 and a plurality of conductive terminals 250 . In the embodiment shown in FIG. 4 , the socket body 210 is made of insulating material such as non-conductive plastic, rubber or synthetic resin, and is injection molded. The conductive terminal 250 is made of metal or its alloy. The socket body 210 also has a slot 220 . In this embodiment, one side of the slot 220 is inserted into the conductive terminal 250 , and the other end is inserted into the bearing seat 120 . The front edges of the two short sides of the socket body 210 respectively include card slots 212 , and the opposite short sides of the card slot 212 have notches 214 . In addition, the socket body 210 preferably further has two ground plates 240 respectively disposed on two sides of the slot 220 for positioning on a printed circuit board (not shown).

Please also refer to FIG. 5 , the slot 212 is preferably engaged with the hook portion 134 , so that the electrical connector plug 100 and the electrical connector receptacle 200 are engaged and positioned with each other. The notch 214 is disposed relative to the unconnected portion 140 . What needs to be explained here is that when the bearing seat 120 of the electrical connector plug 100 is plugged into the slot 220 of the electrical connector receptacle 200 , the positioning elastic arm 130 also has a slope 146 on the upper edge of the hook portion 134 and the receptacle body 210 The slope 216 is set opposite. Therefore, when operating, the user only needs to apply force toward the electrical connector socket 200 , and the inclined surfaces 146 , 216 can be easily fitted and positioned. In addition, in the embodiment shown in FIG. 5 , the engaging groove 212 also includes a slight angle, that is, a slight angle inclined to the assembly direction, for increasing the effect of engaging with the hook portion 134 . Of course, the shape of the hook portion 134 is preferably set corresponding to the shape of the groove 212 . In other words, the engaging groove 212 is inwardly inclined, and the hook portion 134 is outwardly inclined. However, in other different embodiments, the hook portion 134 and the slot 212 may also be male-female engaging structures of other different shapes.

Fig. 6 is a cross-sectional view of the electrical connector assembly of the present invention along line A-A. In this embodiment, the conductive terminal preferably further has an elastic arm 252 for contacting with the contact end 710 of the flexible cable 700 to form electrical conduction. Wherein, since the bearing base 120 of the electrical connector plug 100 has an inclined surface 122, when the electrical connector plug 100 is plugged into the electrical connector receptacle 200, the longer the insertion length of the bearing base 120 is, the more it can be connected with the electrical connector. The socket 200 forms a tight fit. In particular, the elastic arm 252 of the conductive terminal 250 is supported by the flat portion 222 of the socket body 210 , so that the contact end 710 of the flexible cable 700 is in close contact with the elastic arm 252 . In addition, since the front edge of the inclined surface 122 has a protruding portion 124 , and its height is preferably higher than the height of the flexible cable 700 disposed on the bearing seat 120 . Therefore, when the electrical connector plug 100 is inserted into the slot 220 of the electrical connector receptacle 200, it will not interfere with the elastic arm 252 or other parts of the slot 220 due to other factors such as warpage or poor assembly of the flexible cable 700. And affect plugging.

In the embodiment shown in FIG. 6, the conductive terminal 250 of the electrical connector socket 200 is preferably a dual in-line package (Dual In-line Package, DIP), so as to be soldered and positioned with a printed circuit board (not shown). . However, in other different embodiments, the conductive terminals 250 can also be soldered and positioned on the printed circuit board by using surface mount technology (Surface Mount Technology, SMT) or single in-line package (SIP).

Fig. 7 is a diagram showing an operational embodiment of the electrical connector assembly of the present invention. By pressing the positioning elastic arms 130 on both sides of the electrical connector plug 100 , the hook portion 134 disengages from the slot 212 of the electrical connector receptacle 200 , so that the electrical connector plug 100 is disengaged from the electrical connector receptacle 200 . In other words, through the operation of the two positioning elastic arms 130 , the electrical connector plug 100 can be easily plugged into and removed from the electrical connector receptacle 200 for stable positioning, avoiding loosening and smooth signal transmission.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the specification of the essential technical content of the present invention. An equivalent replacement is considered to be covered in the scope of this patent.
