Description

Circuit board structure and connector with the same

technical field

The utility model relates to a signal transmission device, in particular to a circuit board and a connector.

Background technique

As the command cycle of electronic components is getting faster and the storage unit capacity is getting higher and higher, the transmission volume of the wire must also be increased accordingly, and a common method is to increase the number of pins accordingly. Since the pins on the connector must be in contact with the pins of the electronic component or the storage unit, the more pins there are, the greater the resistance, and the user must exert a greater force to complete the insertion and removal. Specifically, the resistance produced by each pin is fixed, and the total group force is proportional to the number of pins, so the more pins, the greater the total resistance.

As shown in FIG. 10 and FIG. 11, a common connection method is to set a circuit board 91 in the connector, and the circuit board 91 is provided with a plurality of metal electrodes (that is, commonly known as gold fingers) as pins, and the other On the one hand, the electronic component uses a plurality of elastic pieces 92 as pins. When the connector is connected to the electronic component, the circuit board 91 of the connector first pushes away the elastic pieces 92 on the electronic component, and then the circuit board 91 can be inserted into the electronic component. Thereby, the metal electrodes of the connector are electrically connected with the elastic pieces 92 of the electronic component. In the past, the number of the elastic pieces 92 was relatively small. When inserting the circuit board 91 , the user could know whether the angle of the circuit board 91 is correct through the elasticity of the elastic pieces 92 . However, nowadays, the number of the elastic pieces 92 is large, and the user cannot easily perceive the elasticity of the elastic pieces 92. Therefore, the circuit board 91 is often inserted into the electronic component at the wrong angle. At this time, the force of the user may cause the elastic sheet 92 to undergo plastic bending deformation, or the entire elastic sheet 92 may fall off and be pushed into the depth of the electronic component, which is commonly known as a pin collapse condition, and the electronic component can no longer be reliably electrically connected to the connector. connection, must be replaced or repaired.

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

In order to achieve the above-mentioned purpose, the circuit board structure proposed by the present utility model has:

A board body, which includes:

a first deck; and

a connecting end surface, which is connected to the first board surface, and the connecting end surface is perpendicular to the first board surface;

at least one protruding portion, which is disposed on the connecting end surface of the board body and protrudes in a direction parallel to the first board surface; and

A plurality of metal electrodes, at least one of the plurality of metal electrodes is disposed on the first board surface.

In order to achieve the above-mentioned purpose, the connector proposed by the present utility model has:

a shell; and

A circuit board structure as described above, the circuit board structure penetrates the casing; the protruding direction of the at least one protruding portion of the circuit board structure is parallel to the insertion direction of the connector.

In the aforementioned circuit board structure, the thickness of each of the at least one protruding portion is tapered from the connecting end surface to the direction away from the board body.

In the aforementioned circuit board structure, the width of each of the at least one protruding portion is tapered from the connecting end surface to the direction away from the board body.

In the aforementioned circuit board structure, the connecting end surface and the at least one protruding portion form a wave-shaped front edge.

In the circuit board structure as described earlier:

The board body further includes a second board surface, which is opposite to the first board surface, and the connecting end surface is connected between the first board surface and the second board surface; and

At least one of the plurality of metal electrodes is disposed on the second plate surface.

In the aforementioned circuit board structure, the metal electrodes include at least one first-length metal electrode and at least one second-length metal electrode, and each of the at least one first-length metal electrode has a length and each of the at least one second length The lengths of the metal electrodes are not the same.

In the above-mentioned circuit board structure, the metal electrode further comprises at least one third-length metal electrode, and the length of each of the at least one third-length metal electrode is greater than the length of the at least one first-length metal electrode and each of the at least one The length of the second length metal electrode.

At least one bump is selectively engaged with the electronic device.

Therefore, when the connector of the present invention is connected to other devices, the protruding portion of the circuit board structure will first contact some pins of the device, but the board body has not yet contacted the pins of the device. When the protruding portion is in contact with part of the pins of the device, the contact pins can be pushed away first. In other words, at this time, the user only needs to push away part of the pins to enable the protruding portion of the circuit board structure of the present invention to be inserted into the device, so only a small pushing force can resist the resistance of the pins. As the user continues to push the connector of the present invention, the circuit board structure goes deeper into the device, and the board body comes into contact with the pins. Since some of the pins have been propped up by the protruding parts, the resistance to be resisted when inserting the board into the device is only the resistance of part of the pins. By inserting the circuit board structure into the device in sections, the thrust applied by each section is small, so even if the insertion direction is slightly skewed, the user can feel the state of the pins, and will not suffer from excessive force. The phenomenon of pin collapse occurs when the pin is bent directly or pushed into the depth of the device.

The connecting end surface 13 is connected between the first board surface 11 and the second board surface 12 and is perpendicular to the first board surface 11 and the second board surface 12 . The normal line of the connection end face 13 is parallel to the insertion direction D of the connector.

The protruding portion 20 is disposed on the connecting end surface 13 of the board body 10 and protrudes in a direction parallel to the first board surface 11 . In other words, the protruding direction of the protruding portion 20 is parallel to the insertion direction D of the connector. In this embodiment, from the connecting end surface 13 to the direction away from the board body 10 , the thickness T of each of the at least one protruding portion 20 is tapered and the width W is tapered. In other words, the thickness T and the width W of the protruding portion 20 in the insertion direction D are tapered.

The metal electrodes 30 (commonly known as gold fingers) can be arranged on the first board surface 11 or on the second board surface 12 , but in this embodiment, the metal electrodes 30 are simultaneously arranged on the first board surface 11 and the second board surface 12 . on the second board surface 12 . The metal electrodes 30 may have different lengths, and thus may have different distances from the connection end face 13 .
