Detailed ways

Below in conjunction with accompanying drawing and preferred embodiment the utility model is further described.

As shown in FIGS. 1 and 2 , FIG. 1 is a perspective view of the electronic device of the present invention, and FIG. 2 is an exploded view of the electronic device of the present invention. This embodiment provides an electronic device, which includes an electronic circuit board 3 and an electrical connector. The electrical connector includes an insulating body 1 and a plurality of terminals 2 . The terminal 2 includes three first terminals 21 .

The types of the insulating body 1 and the plug in this embodiment are not limited. For example: the specification of the insulating body 1 can be a 3.5mm, 2.5mm, etc. earphone socket of level 3 or level 4. The plug is a plug corresponding to the specification of the above-mentioned insulating body 1 . In FIGS. 1-7 , the insulating body 1 is described by taking a four-level 3.5 mm specification as an example, but it is not limited thereto.

As shown in Figure 1 and Figure 3. FIG. 3 is a three-dimensional exploded view of the electronic device of the present invention. The insulating housing 1 in this embodiment is roughly rectangular and includes a top surface 11 and a bottom surface 12 . The insulating body 1 is recessed from the top surface 11 to form six terminal slots 102 . Some of the terminal slots 102 have substantially the same shape.

As shown in FIG. 5 , it is a plan view of the electronic device of the present invention. The insulating body 1 defines a vertical imaginary plane W and a horizontal imaginary plane H. The side of the insulating body 1 is recessed inwardly to form a cylindrical slot 10 . The cylindrical socket 10 forms an accommodating space 100 . The cylindrical socket 10 is left-right symmetrical with respect to the vertical virtual plane W. The virtual horizontal plane H is substantially parallel to the top surface 11 and the bottom surface 12 of the insulating body 1 . The vertical imaginary plane W and the horizontal imaginary plane H are perpendicular to each other and both pass through both ends of the cylindrical socket 10 .

As shown in Figure 3 and Figure 4. FIG. 4 is a cross-sectional view of the electronic device of the present invention. Six terminal contact holes 101 are formed facing the inner walls of the cylindrical socket 10 . The accommodating space 100 communicates with the terminal slot 102 through the terminal contact hole 101 .

More specifically, the terminal contact holes 101 are arranged in two rows facing each other at a position on the side of the inner wall of the cylindrical slot 10 close to the top surface 11 . Part of the terminal contact holes 101 in this embodiment are approximately pentagonal, but may also be other polygonal shapes. The shape of the terminal contact hole 101 may also be a combination of various shapes. The shape and number of the terminal contact holes 101 are not intended to limit the present invention.

As shown in Figure 2 and Figure 4. Each first terminal 21 is in an irregular continuous bent shape. The first terminal 21 includes a welding portion 214 , a first contact protrusion 210 , a second contact protrusion 211 and a connection portion 219 connecting the first contact protrusion 210 and the second contact protrusion 211 .

More specifically, the first contact protrusion 210 and the second contact protrusion 211 are located on the same bending surface of the first terminal 21 and substantially opposite to each other. The appearance of the first contact protrusion 210 and the second contact protrusion 211 is substantially circular protrusion.

as shown in picture 2. Each first terminal 21 is disposed in the terminal slot 102 of the insulating housing 1 along a first direction. The first direction in this example is the y-axis, but it is not intended to limit the present invention.

As shown in Figure 1. The welding portions 214 of the two first terminals 21 that are closer to the opening of the cylindrical slot 10 are disposed on the left side of the insulating housing 1 (ie, the left side in FIG. 1 ). The welding portion 214 of the other first terminal 21 is disposed on the right side of the insulating housing 1 (ie, the right side in FIG. 1 ).

As shown in Figure 5. Each of the first contact protruding portion 210 and the second contact protruding portion 211 protrudes from the corresponding terminal contact hole 101 substantially closely (as shown in FIG. 4 ). In other words, the shapes of the first contact protrusion 210 and the second contact protrusion 211 pass through the terminal contact hole 101 substantially without any gap. The first contact protrusion 210 and the second contact protrusion 211 are located on two sides of the vertical virtual plane W, respectively.

In summary, the first terminals 21 are arranged in a row from front to back, and the first contact protrusions 210 and the second contact protrusions 211 are disposed on opposite sides of the cylindrical socket 10 . The left and right positions of the first contact protrusion 210 and the second contact protrusion 211 can be replaced with each other. However, the left and right positions of the first contact protrusion 210 and the second contact protrusion 211 are not intended to limit the present invention.

Therefore, when the plug is inserted into the cylindrical socket 10 , if one of the first contact protrusion 210 and the second contact protrusion 211 cannot be reset smoothly due to force. Then the other contact protrusion can still be electrically connected to the plug, so as to provide an electrical connector with better structural reliability.

as shown in picture 2. The electronic device in this embodiment further includes a detection terminal 22 , a second terminal 23 and a fixed terminal 24 . The detection terminal 22 , the second terminal 23 and the fixed terminal 24 are all disposed on the insulating body 1 along the direction of the y-axis.

As shown in Figure 2 and Figure 4. The second terminal 23 includes a resilient contact portion 230 and a welding portion 231 . The second terminal 23 is disposed in the insulating body 1 along a second direction. In this embodiment, the second direction is the direction of the x-axis, but not limited thereto. The elastic contact portion 230 of the second terminal 23 passes through the inner wall of the cylindrical slot 10 .

As shown in Figure 2 and Figure 4. The detection terminal 22 is located at the bottom of the accommodating space 100 and includes a welding portion 220 . The detection terminal 22 is adjacent to the second terminal 23 and abuts against the elastic contact portion 230 . When the plug is inserted into the cylindrical slot 10 , the elastic contact portion 230 is bent and separated from the detection terminal 22 under force. When the plug is removed, the elastic contact portion 230 returns to its original shape and abuts against the detection terminal 22 .

In other words, the detection terminal 22 is electrically connected to the second terminal 23 and is a normally closed contact. When the plug is not inserted into the cylindrical slot 10 , the detection terminal 22 and the second terminal 23 are in contact with each other and are in a conduction state. After the plug is inserted into the cylindrical slot 10 , the detection terminal 22 and the second terminal 23 are separated from each other and in a non-conductive state.

As shown in Figure 3 and Figure 4. The fixed terminal 24 includes a wave-shaped elastic arm 240 . The fixed terminal 24 is disposed on an opposite side of the second terminal 23 and partially passes through the inner wall of the cylindrical slot 10 . The fixed terminal 24 and the second terminal 23 define a buckle structure.

In other words, when the plug is inserted into the cylindrical slot 10 , the three first terminals 21 abut against the plug one after another. Then the elastic contact portion 230 of the second terminal 23 and the elastic arm 240 of the fixed terminal 24 are stretched away from each other and engaged with the plug. After the plug is removed from the cylindrical socket 10 , the elastic contact portion 230 and the elastic arm 240 return to their original shape.

As shown in Figure 5. The vertical imaginary plane W and the horizontal imaginary plane H equally divide the tubular slot 10 and define four quadrants. The upper right and upper left of the electronic device (ie, the upper right and upper left of FIG. 5 ) are respectively the first quadrant and the second quadrant. The lower left and lower right of the electronic device (ie, the lower left and lower right of FIG. 5 ) are respectively the third quadrant and the fourth quadrant.

In other words, the first quadrant is located at the upper right, and the order from the first quadrant to the fourth quadrant is determined by taking the central axis of the cylindrical slot 10 as the center and rotating counterclockwise.

As shown in Figure 5. The first contact protrusion 210 and the second contact protrusion 211 are respectively disposed in the first quadrant and the second quadrant.

As shown in FIG. 5A , it is another plan view of the electronic device of the present invention. The first contact protrusion 210 and the second contact protrusion 211 are respectively disposed in the second quadrant and the fourth quadrant.

As shown in FIG. 5B , it is another plan view of the electronic device of the present invention. The first contact protrusion 210 and the second contact protrusion 211 are respectively disposed in the first quadrant and the third quadrant.

The positions of the first contact protrusion 210 and the second contact protrusion 211 in FIGS. 5 , 5A, and 5B above can provide good structural reliability and connection quality when the plug is inserted into the electrical connector. Furthermore, the plurality of terminals 2 in this embodiment can be used for signal transmission, but the purpose of the terminals 2 is not intended to limit the present invention.

As shown in FIG. 6 , it is a three-dimensional exploded view of the electronic device of the present invention. Each first terminal 21 in this embodiment is provided with a third contact protrusion 212 . The shape of the third contact protrusion 212 is substantially the same as that of the first contact protrusion 210 or the second contact protrusion 211 .

As shown in Figure 6. A terminal contact hole 101 corresponding to the third contact protrusion 212 is formed on the inner wall of the cylindrical socket 10 . The third contact protrusion 212 passes through the corresponding terminal contact hole 101 substantially seamlessly.

As shown in FIG. 7 , it is a plan view of the electronic device of the present invention. The third contact protrusion 212 is located on a side of the horizontal virtual plane H adjacent to the bottom surface 12 . The first contact protrusion 210 and the second contact protrusion 211 are located on a side of the horizontal virtual plane H adjacent to the top surface 11 . The positions of the first, second, and third contact protrusions 210 , 211 , 212 are not intended to limit the present invention.

as shown in picture 2. In this embodiment, the electronic circuit board 3 and the electrical connector are connected in a broken board type. In other words, the electronic circuit board 3 includes a surface 30 and a notch 31 . The electrical connector is embedded in the notch 31 of the electronic circuit board 3 .

As shown in Figure 1. The welding portions 214 , 231 , 220 of the first terminal 21 , the second terminal 23 and the detection terminal 22 are respectively bent and extended along the outer wall of the insulating housing 1 . The welding portions 214 , 231 , 220 of the terminals are respectively welded to the surface 30 and electrically connected to the electronic circuit board 3 .

In summary, the electronic device of the present invention has the following effects:

1. When the plug is inserted into the cylindrical slot, the first, second, and third terminals contact the protrusions to be displaced by force; when the plug is removed, if the first, second, and third terminals contact one of the protrusions If it cannot be reset smoothly, the contact protrusions of the other two terminals are still electrically connected to the plug, so as to provide an electronic device with high reliability.

2. The broken board connection makes the electrical connector assembled on the electronic circuit board require less space, which is conducive to the thinning of the electronic device.

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
