Description

Golden finger connector, circuit board, female connector and related assembly and equipment thereof
Technical Field
The invention relates to the technical field of network equipment connection, in particular to a golden finger connector, a circuit board, a female connector and related components and equipment thereof.
Background
As the size of communication modules becomes smaller and the capacity becomes larger, increasing the communication rate by increasing the number of channels becomes a simple and feasible approach. The golden finger connector is a commonly used connector and is characterized in that signal transmission between the golden finger connector and a female connector is realized through contact between a golden finger and a contact elastic sheet in the female connector at the opposite end. Most of the golden finger connectors adopted in the industry at present comprise a single row of golden fingers, and because the number of channels of the single row of golden fingers is small, the golden finger connectors adopting the single row of golden fingers have the defect of low communication speed. In order to solve the technical problem, the technical staff starts to research and adopt the golden finger connector comprising the double rows of golden fingers, but the research shows that the service life of the golden finger connector is finally shortened due to the problems of surge overshoot, current backflow and the like of the golden finger connector comprising the double rows of golden fingers.

The second golden finger is opposite to the gap between the adjacent first rows of golden fingers and is positioned in the same row, and the adjacent two golden fingers forming the slid gap are not contacted in the sliding process of the contact elastic sheet, so that the first golden finger is prevented from being simultaneously powered off after being contacted and powered on when the golden finger connector is inserted into the female connector or from being simultaneously connected with the first golden finger to be powered on when the golden finger connector is pulled out of the female connector, the problems of current surge overshoot, current backflow and the like generated in the plugging and unplugging process are further avoided, and the service life of the golden finger connector is prolonged.

The plurality of second gold fingers 151 are located in the same row and arranged at regular intervals, and the first row of gold fingers 11 and the second row of gold fingers 15 are arranged side by side and arranged on the substrate 12 at intervals, wherein the substrate may be a circuit board of an optical/electrical module or a sub-board connected with the circuit board. It should be noted that the contact portion of the contact elastic piece and any one of the golden fingers may be located on a straight line perpendicular to the insertion direction of the golden finger connector. The second gold fingers 151 and the plurality of first gold fingers 111 are arranged in a staggered manner, the second gold fingers 151 are opposite to the gaps 113 between the first gold fingers 111, that is, along the insertion direction of the gold finger connector 10, the gaps 113 between two adjacent first gold fingers 111 and the second gold fingers 151 are located in the same row, that is, the gaps 113 and the second gold fingers 151 are both located in the direction parallel to the insertion direction and form a row; when the contact spring passes through the gap 113, the contact spring is connected with the second gold finger 151, and does not contact with the two first gold fingers 111 forming the gap 113 in the process of sliding through the gap 113. It should be noted that the extending direction of the row where the gap 113 and the second gold finger 151 are located is perpendicular to the extending direction of the row where the second row of gold fingers 15 is located.
Further, a center line a of the gap 113 between every two adjacent first gold fingers 111 along the plugging and unplugging direction of the gold finger connector 10 substantially coincides with a center line of the contact elastic sheet sliding through the corresponding gap 113 along the plugging and unplugging direction of the gold finger connector 10, so as to ensure that the contact elastic sheet and the second gold finger 151 can be well connected. Furthermore, the width of the gap 113 between every two first gold fingers is greater than the width of the contact spring sheet contacting the second gold finger 151. On the premise that the plugging tolerance does not exist, the contact spring sheet cannot be contacted with the first golden finger forming the gap 113 when and after sliding through the corresponding gap 113. Therefore, the contact elastic sheet can smoothly pass through the gap 113, and the contact of the contact elastic sheet contacted by the second golden finger 151 and the first golden finger when the golden finger connector 10 is hot-plugged is avoided. It can be understood that, during the assembly process, when the golden finger connector 10 is inserted into or pulled out from the female connector and the assembly tolerance is constant, the width of the gap 113 is such that the contact spring contacted by the second golden finger 151 is not contacted with the first golden finger, that is, the width of the gap 113 is greater than the sum of the contact spring and the assembly tolerance.
The gold finger connector 10 of the present application is provided with two rows of gold fingers, which can improve the speed of the connector, and at the same time, the second gold finger 151 of the second row of gold fingers 15 and the gap 113 between the two first gold fingers 111 of the first row of gold fingers 11 are located in the same row, when the connector is plugged into the female connector, the contact spring sheet contacting with each second gold finger 151 slides through the gap 113 and contacts with the second gold finger 151, and the contact spring sheet is isolated from the corresponding adjacent two first gold fingers 111 sliding through the gap 113, and the contact spring sheet does not contact with the adjacent two first gold fingers 111 sliding through the gap 113 in the sliding process, thereby avoiding the problems of the first gold fingers 111 being powered down at the same time after being powered on by the contact spring sheet or being simultaneously connected with the first gold fingers and powered up when being pulled out, and further avoiding the problems of current overshoot and current pouring in the inserting process, meanwhile, the contact spring sheet only needs to be electrified up and down with the second golden finger 151, and the electrification up and down is not repeated.
Referring to fig. 2 again, a center line B of each of the second gold fingers 151 along the plugging direction of the gold finger connector 10 and a center line a of the gap 113 between two corresponding adjacent first gold fingers 111 along the plugging direction of the gold finger connector 10 substantially coincide with each other. The substantial coincidence means that the center line a and the center line B are completely coincident on a straight line, or may not completely coincide, that is, the center line B is located on both sides of the center line a and the distance from the center line a falls within the manufacturing tolerance range of the golden finger connector 10. The center line B of each second gold finger 151 and the center line a of the gap 113 are substantially overlapped to ensure that the contact elastic sheet corresponding to the second gold finger 151 and the second gold finger 151 achieve good contact, so as to achieve a better signal transmission effect.
Further, the minimum distance between the first row of gold fingers 11 and the second row of gold fingers 15 meets the requirement of electrical short circuit, and the maximum distance is smaller than the length of the shortest gold finger in the gold finger connector 10. The electrical short circuit means that the first row of golden fingers 11 and the second row of golden fingers 15 are prevented from generating a short circuit phenomenon through conducting wires or direct contact, and the maximum distance satisfies that the contact spring pieces connected with the second row of golden fingers 15 have enough stroke when the golden finger connector 10 is plugged with the female connector and ensure normal contact with the second golden fingers 151.

As a specific implementation manner of the embodiment of the present invention, a portion of the plurality of first gold fingers 111 distributed on each side of the reference line satisfies: the length of the grounded first golden finger is greater than that of the first golden finger for connecting the communication signal; the reference line is perpendicular to the plugging direction of the golden finger connector 10 and divides a plurality of shortest first golden fingers in the first golden fingers into two equal parts along the length of the plugging direction, so that the contact elastic pieces matched with the first row of golden fingers 11 can be sequentially electrically contacted with the first golden fingers which are grounded and the first golden fingers which are communicated with the communication signals in sequence, and the golden finger connector 10 is ensured to be normally electrically connected with the female connector. The reference line in this embodiment is the center line of the first gold finger that is connected with the communication signal.
As another specific implementation manner of the embodiment of the present invention, in a case that the plurality of first gold fingers 111 at least include a first gold finger connected to ground, a first gold finger transmitting a power signal, and a first gold finger connecting a communication signal, a portion of the plurality of first gold fingers distributed on each side of the reference line satisfies: the length of the grounded first golden finger is greater than that of the first golden finger for transmitting the power signal, and the length of the first golden finger for transmitting the power signal is greater than that of the first golden finger for receiving the communication signal. At least including means that a plurality of the first gold fingers 111 may also include gold fingers transmitting power signals or other non-contact signals.
Referring to fig. 3, specifically, the longest first gold finger is the first gold finger connected to the ground, the shortest is the first gold finger connected to the communication signal, and the lengths of the portions of each gold finger located at the two sides of the reference line are equal. As is common to those skilled in the art, the length of the grounded gold finger is greater than the length of the gold finger transmitting the power signal, and the length of the gold finger transmitting the power signal is greater than the length of the gold finger transmitting the communication signal. As a person skilled in the art will also appreciate, even if both gold fingers are grounded, or both carry power signals, or both carry communication signals, their lengths are not necessarily exactly equal, or they are substantially equal, and how the so-called substantial equality should be determined, should be based on technical features known to those skilled in the art to achieve the object of the present invention.
Referring to fig. 2, in the present embodiment, the lengths of the grounded first gold finger, the first gold finger for transmitting the power signal, and the first gold finger for connecting the communication signal, which are located on the right side of the reference line O, that is, on the side of the insertion direction, are sequentially decreased.
As another specific implementation manner of the embodiment of the present invention, the lengths of the first gold finger grounded to the portion located on the left side of the reference line O, the first gold finger transmitting the power signal, and the connection signal are equal, or may be different.
Further, in a case that the plurality of second gold fingers 151 at least includes a second gold finger connected to ground, a second gold finger transmitting a power signal, and a second gold finger connecting a communication signal, the right portion of the reference line where the plurality of second gold fingers are distributed all satisfies: the length of the grounded second golden finger is greater than that of the second golden finger for transmitting the power signal, and the length of the second golden finger for transmitting the power signal is greater than that of the second golden finger for receiving the communication signal. Referring to fig. 2, as mentioned above, generally speaking, in the present embodiment, the lengths of the grounded second gold finger, the second gold finger for transmitting the power signal and the second gold finger for making the communication signal on the right side of the reference line, that is, on the side of the insertion direction, of the second row of gold fingers 151 are sequentially decreased, and the lengths of the grounded second gold finger, the second gold finger for transmitting the power signal and the second gold finger for making the communication signal on the left side of the reference line are equal to or different from each other.
As a further specific implementation manner of the embodiment of the present invention, one end of each of the gold fingers in the second row of gold fingers 15, which is far away from the first row of gold fingers 11, is aligned, in this technical solution, since one end of each of the gold fingers in the second row of gold fingers 15, which is far away from the first row of gold fingers 11, is aligned, the substrate of the gold finger connector is divided into more regular areas by the second row of gold fingers 15, thereby facilitating to dispose other devices on the substrate. It should be noted that the alignment means that the aligned end of each gold finger in the second row of gold fingers 15 is substantially located on the same straight line perpendicular to the plugging direction of the gold finger connector. It should be emphasized that the substantially same straight line means that the end of each gold finger in the second row 15 far from the first row 11 may not be completely located in the same straight line, or the end of each gold finger in the second row 15 far from the first row 11 may form a curve, but the degree of curvature of the curve is limited, which should be understood by those skilled in the art, and will not be described herein again.

It should be noted that, the first row of gold fingers 11 and the second row of gold fingers 15 may include an undefined gold finger, where the undefined gold finger means that one end of the gold finger contacts the contact spring, but the other end of the gold finger is not communicated with the circuit, so that the gold finger cannot transmit the signal to other devices through the circuit after receiving the signal transmitted by the contact spring.
In other embodiments, the first row of gold fingers 11 and the second row of gold fingers 15 are both located on the front surface of the gold finger connector 10, and the plurality of first gold fingers 111 at least include a gold finger connected to ground, a gold finger transmitting a power signal, and a gold finger connecting a communication signal; and the plurality of second gold fingers 151 at least includes a gold finger connected to ground and a gold finger connected to a communication signal.
