Description
Technical Field
The present invention relates to a signal transmission device, and more particularly to a circuit board and a connector.
Background
As the command cycle of the electronic device is faster and the capacity of the storage unit is higher, the transmission amount of the wires must be correspondingly increased, and the number of the pins is increased correspondingly by a common method. Since the pins of the connector must be in contact with the pins of the electronic component or the storage unit, the more the pins are, the greater the resistance is, and the user must apply a greater force to complete the insertion and extraction. Specifically, the resistance generated by each pin is fixed, and the total resistance is proportional to the number of the pins, so that the more pins, the greater the total resistance.
As shown in fig. 10 and 11, a circuit board 91 is disposed in the connector, and the circuit board 91 is provided with a plurality of metal electrodes (also known as gold fingers) as pins, and the electronic component is provided with a plurality of spring pieces 92 as pins, when the connector is connected to the electronic component, the circuit board 91 of the connector first pushes the spring pieces 92 of the electronic component away, and then the circuit board 91 can be inserted into the electronic component, so that the metal electrodes of the connector and the spring pieces 92 of the electronic component form an electrical connection. Conventionally, the number of the resilient pieces 92 is small, and a user can know whether the angle of the circuit board 91 is correct or not by the elasticity of the resilient pieces 92 when inserting the circuit board 91. However, the number of the spring pieces 92 is large, so that the user cannot easily perceive the elasticity of the spring pieces 92, and the circuit board 91 is often inserted into the electronic component at a wrong angle. At this time, the user's force may cause the elastic piece 92 to be plastically bent and deformed or the entire elastic piece 92 may be dropped and pushed into the deep part of the electronic component, i.e. a so-called snap condition occurs, and thus the electronic component cannot be reliably electrically connected to the connector any more, and must be replaced or maintained.
In view of the above, a better solution is proposed, and a problem to be solved is needed in the art.

When the convex part contacts with part of the pins of the device, the contacted pins can be pushed away first. In other words, at this time, the user can insert the protruding portion of the circuit board structure into the device by pushing away only a portion of the pin, so that the resistance of the pin can be resisted only by a small pushing force. Along with the user continuously promotes the utility model discloses a connector, the circuit board structure just more deepens the device, and the plate body just contacts with the pin. Since part of the pins are already spread by the projections, the resistance to which the board is inserted into the device is only a part of the resistance of the pins. By inserting the circuit board structure into the device in a sectional manner, the pushing force applied by each section is small, so that even if the inserting direction is slightly inclined, a user can feel the state of the pins, and the phenomenon of pin collapse caused by bending the pins directly or pushing the pins into the deep part of the device due to excessive force is avoided.

Detailed Description
The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.
Please refer to fig. 1 and fig. 2 first. The utility model provides a connector, it has a casing 1 and a circuit board structure 2, and the connector definition one inserts the direction D and inserts the direction for the connector when inserting an electron device moving direction. In addition, the connector is also provided with an elastic sheet 3 selectively.
The circuit board structure 2 is disposed through the housing 1, and the circuit board structure 2 has a board body 10, at least one protrusion 20, and a plurality of metal electrodes 30. The plate 10 may include a first plate 11, a second plate 12 and a connecting end 13. The first plate surface 11 and the second plate surface 12 are two opposite side surfaces of the plate body 10, and the first plate surface 11 is parallel to the second plate surface 12. The connecting end surface 13 is connected between the first plate surface 11 and the second plate surface 12, and is perpendicular to the first plate surface 11 and the second plate surface 12. The normal line of the connection end surface 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 plate body 10 and protrudes in a direction parallel to the first plate surface 11. In other words, the projecting direction of the projecting portion 20 is parallel to the insertion direction D of the connector. In the present embodiment, the at least one protrusion 20 has a tapered thickness T and a tapered width W from the connecting end surface 13 toward the direction away from the plate body 10. In other words, the protruding portion 20 is tapered in both thickness T and width W in the insertion direction D.
The metal electrodes 30 (also called gold fingers) may be disposed on the first board surface 11 or the second board surface 12, but in this embodiment, the metal electrodes 30 are disposed on both the first board surface 11 and the second board surface 12. The metal electrodes 30 may have different lengths and thus may not be at the same distance from the connection end surface 13.
In the present embodiment, the metal electrode 30 may include at least one first length metal electrode 31 and at least one second length metal electrode 32, and may further include at least one second length metal electrode 32. The length of the first-length metal electrode 31 is different from the length of the second-length metal electrode 32, and specifically, the length of the first-length metal electrode 31 is smaller than the length of the second-length metal electrode 32, and the length of the third-length metal electrode 33 is greater than the length of the first-length metal electrode 31 and the length of the second-length metal electrode 32. In other words, the distance between the length of the third-length metal electrode 33 and the connection end surface 13 is smaller than the distance between the length of the second-length metal electrode 32 and the connection end surface 13, and the distance between the length of the second-length metal electrode 32 and the connection end surface 13 is smaller than the distance between the length of the first-length metal electrode 31 and the connection end surface 13. Even more, at least one metal electrode 30 may extend to one of the protrusions 20, for example, the third length metal electrode 33 may extend to the protrusion 20.
For example, the longest third length metal electrode 33 may be grounded to ensure that the circuit board structure 2 is grounded first when the device is connected and conducted, so as to protect the electronic components on the circuit board structure 2. The second length metal electrode 32 can be connected with a power supply, and then the first length metal electrode 31 is connected with a signal, so that the circuit board structure 2 starts to operate by electrifying firstly when the circuit board structure 2 is jointed with a device, and the waiting time for waiting for starting the circuit board structure 2 after jointing is reduced. In other embodiments, the length relationship and the function of the metal electrode 30 are not limited to those disclosed above, and may be configured differently according to different devices connected thereto.
Referring to fig. 3 to fig. 6, an electronic device connection system is shown, which includes the connector and an electronic device a. The electronic device a has a plurality of pins a 1. With the circuit board structure 2, when the connector is connected to the electronic device a, the protrusion 20 of the circuit board structure 2 first contacts with a portion of the pin a1 of the electronic device a, but the board 10 does not contact with the pin a1 of the electronic device a. When the protrusion 20 contacts the partial pin a1 of the electronic device a, the contacted pin a1 is pushed away first. In other words, at this time, the user can insert the protruding portion 20 of the circuit board structure 2 into the electronic device a only by pushing the pin a1 away, so that the resistance of the pin a1 can be resisted only by a small pushing force. As the user continuously pushes the connector of the present invention, the circuit board structure 2 further goes into the electronic device a, and the board 10 contacts with the pin a 1. Since part of the pin a1 is already spread by the protrusion 20, the resistance to insert the board 10 into the electronic device is only the resistance of the part of the pin a 1. By inserting the circuit board structure 2 into the electronic device a in a stepwise manner, the pushing force applied to each stage is small, so that even if the insertion direction is slightly inclined, the user can feel the state of the pin a1, and the pin a1 is not deformed or the pin a1 is pushed into the electronic device a by improper force, so that the pin is not collapsed.
Please refer to fig. 5 and fig. 7. The elastic sheet 3 of the connector is fixedly arranged on the shell 1, and the elastic sheet 3 is provided with at least one convex block 3 a. When the connector is inserted into the electronic device a, the protrusion 3a of the spring piece 3 is engaged with the electronic device a, so that the connector does not fall off from the electronic device a. When the user wants to separate the connector from the electronic device a, the user only needs to press the elastic sheet 3 to make the projection 3a fall off the engagement state, so that the connector can be pulled out from the electronic device a.
Please refer to fig. 8. In other embodiments, the connection end surface 13A and the protrusion 20A of the circuit board structure 2 may be curved surfaces, and the connection end surface 13A is an inward curved surface and the protrusion 20A is an outward curved region, so that the connection end surface 13A and the protrusion 20A together form a wavy front edge on the circuit board structure 2A. Therefore, the effect of dispersing the resistance by inserting the circuit board structure 2A in multiple stages can also be achieved.
Please refer to fig. 9. In other embodiments, the length of the metal electrode 30B may be the same, and the same effect of electrically connecting with other devices can be achieved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
