As described in the background art, currently mainstream USB connectors are mainly classified into USB a Type and USB Type C Type, and in order to facilitate transmission and ensure the universality of the connectors, the USB association has certain requirements on the size, transmission rate and frequency of USB connectors of different types. Due to the limitation of size, the USB connector plug in the related art only has a signal transmission function, and cannot meet the requirements of security protection for data storage, recovery and the like in a database.
Based on the above consideration, in order to solve the problem that the USB connector in the related art cannot show the requirements of security protection such as data storage and recovery in the data transmission process, the inventors have conducted intensive research to design a USB connector plug capable of meeting the requirements of security protection such as data storage and recovery in the data transmission process.
The USB connector disclosed by the application can be applied to high-speed signal transmission between two or more sets of database systems or circuit boards, but is not limited to the high-speed signal transmission, and is applicable to the fields with requirements on data transmission rate and functions.
Fig. 1 shows a schematic structural view of a first terminal 2 and a second terminal 3 of a USB connector plug in an embodiment of the present invention, fig. 2 shows a schematic structural view of a state in which a first mounting portion 21 and a second mounting portion 31 of the USB connector plug are mounted on an insulating plate 1 in an embodiment of the present invention, and fig. 3 shows a schematic structural view of a side view of the first terminal 2 and the second terminal 3 of the USB connector plug in an embodiment of the present invention.
Referring to fig. 1 to 3, the present application provides a USB connector plug including an insulating plate 1, a plurality of first terminals 2 and a plurality of second terminals 3.
The insulating plate 1 has a connection side, and a plurality of first terminals 2 are arranged along first direction interval, and all fixed connection is in the connection side. The plurality of second terminals 3 are arranged at intervals along the first direction and are all fixedly connected to the connecting side, a first terminal 2 is arranged between every two adjacent second terminals 3, and each first terminal 2 and any adjacent second terminal 3 have a height difference in the second direction. Wherein the first direction is parallel to the insulating plate 1 and perpendicular to the extending direction of the first terminal 2; the second direction is perpendicular to the first direction and perpendicular to the insulating plate 1. And at least one pair of differential signal terminal pairs is formed in the plurality of first terminals 2, each pair of differential signal terminal pairs including two adjacent first terminals 2; at least one of the plurality of second terminals 3 is a control terminal for transmitting a control signal.
Specifically, the differential signal terminal pair is used for transmitting a high-speed differential signal, and includes two adjacent first terminals 2, one of which is positive and the other of which is negative, and when a positive and a negative first terminals 2 are close to each other, association can be formed, so that a differential signal pair is formed, and when the widths of the two first terminals 2 satisfy a specific condition to ensure impedance matching, transmission of the high-speed signal is realized. The plurality of first terminals 2 form a ground terminal and at least one pair of differential signal terminal pairs, and the differential signal terminal pairs form a complete set of differential pairs for transmitting high-speed signals when conditions are appropriate. The second terminal 3 has at least one control terminal and a plurality of low-speed terminals formed therein for transmitting control signals and low-speed signals, respectively.
It can be understood that the differential signal terminal pair including two adjacent first terminals 2 is used as a high-speed transmission terminal for transmitting high-speed data, and the control terminal is used for transmitting a control signal, so as to meet the requirements of data storage, data recovery and the like in the high-speed signal transmission process. In addition, the first terminals 2 and the second terminals 3 have a height difference in the second direction, so that the area covered by all the first terminals 2 and the area covered by all the second terminals 3 can be adjusted in the first direction, and the USB connector plug can meet the size requirement of the USB industry standard. And the existence of the height difference enables signal transmission between the first terminals 2 and the second terminals 3 not to be influenced mutually, the coupling relevance of the differential signal terminal pair is improved, the anti-interference capability of the differential signal terminal pair is further improved, and the quality of control signals transmitted by the control terminals and high-speed data transmitted by the differential signal terminal pair is ensured. Therefore, the USB connector plug not only has high-speed data transmission performance, but also has the performances of data storage, data recovery and the like, and the structural size of the USB enables the connector plug to have better universality and compatibility.
In some embodiments, one of the first terminals 2 forms a ground terminal, the remaining first terminals 2 form even pairs of differential signal terminals, the even pairs of differential signal terminals are symmetrically distributed on two sides of the ground terminal, and the orthographic projection of the control terminal towards the plane of the insulating plate 1 is located between the orthographic projection of two adjacent first terminals 2 in a certain differential signal terminal pair towards the plane of the insulating plate 1. The control terminal is inserted between two adjacent first terminals 2 for transmitting the control signal, so that the coupling correlation between two differential signal terminal pairs is reduced to a certain extent, but the control terminal and two corresponding differential signal terminals thereof have a certain height difference in the second direction, so that the problem of the reduction of the coupling correlation caused by the insertion of the control terminal is solved.
In some embodiments, even pairs of differential signal terminal pairs are distributed on both sides of the ground terminal for transmitting high-speed signals, and the control terminal is located between two adjacent first terminals 2 of the differential signal terminal pairs to be able to monitor the data transmission condition of the differential signal terminal pairs in real time.
It can be understood that the control terminal is arranged between two adjacent first terminals 2 of the differential signal terminal pair, so that the data transmission condition of the differential signal terminal pair can be monitored in real time, and data can be stored or recovered according to the data transmission condition, so that the database system still has high safety performance when the data transmission condition is abnormal.
In some embodiments, the number of the first terminals 2 is five, two pairs of differential signal terminals are formed in the five first terminals 2, the two pairs of differential signal terminals are symmetrically distributed on both sides of the ground terminal, the number of the second terminals 3 is six, two of the six second terminals 3 are configured as control terminals, and the two control terminals are symmetrically disposed corresponding to the two pairs of differential signal terminals, respectively.
That is, one of the five first terminals 2 is a ground terminal, and a pair of differential signal terminal pairs (composed of two first terminals 2 and used for transmitting high-speed signals) and three second terminals 3 (one of the three second terminals 3 located on the same side is used as a control terminal and used for transmitting control signals, and the other two second terminals 3 are used as low-speed terminals and used for transmitting low-speed signals) are respectively distributed on two sides of the ground terminal in the longitudinal extension direction. The three second terminals 3 located on the same side and the two first terminals 2 in the differential signal terminal pair located on the same side are arranged in an interpenetration mode, and the projection of each control terminal on the insulating plate is located between the projections of the differential signal terminal pair on the insulating plate.
Therefore, in the first direction, the terminal arrangement sequence of the entire USB connector is: the first terminal 2 (differential signal terminal), the second terminal 3 (control terminal), the first terminal 2 (differential signal terminal), the second terminal 3 (low-speed terminal), the first terminal 2 (ground terminal), the second terminal 3 (low-speed terminal), the first terminal 2 (differential signal terminal), the second terminal 3 (control terminal), the first terminal 2 (differential signal terminal), and the second terminal 3 (low-speed terminal). The six second terminals 3 and the five first terminals 2 are arranged in a staggered mode, and have height differences in the second direction, so that certain space is saved in the first direction, and the size specification of the USB connector can be matched better. It is understood that, the combination of the five first terminals 2 and the six second terminals 3 has two more low-speed terminals compared with the conventional five high-speed terminals and four low-speed terminals (USB connector with 9 pins) for consumer electronics, and the low-speed terminals are used for transmitting control signals to realize data storage and recovery functions in the high-speed data transmission process, so that the combination is more suitable for enterprise-level signal storage and signal transmission, and facilitates control and management of reading and writing of high-speed signals.
In some embodiments, the width of each first terminal 2 along the first direction is greater than the distance between two adjacent second terminals 3, so that the width of the first terminal 2 is required to satisfy impedance matching during high-speed signal transmission.
In some embodiments, each first terminal 2 has a first mounting portion 21, each second terminal 3 has a second mounting portion 31, the first terminal 2 is fixedly connected to the connection side by its corresponding first mounting portion 21, and the second terminal 3 is fixedly connected to the connection side by its corresponding second mounting portion 31.
Specifically, the first mounting portion 21 and the second mounting portion 31 are both soldering pins, one part of which is fixedly connected to the connection side, and the other part of which is soldered to the corresponding PCB pad, so as to realize interconnection of two or more sets of systems or circuit boards.
In some embodiments, a projection of each first mounting portion 21 onto a first plane coincides with a projection of any one of the second mounting portions 31 onto the first plane, wherein the first plane is perpendicular to the first direction.
In some embodiments, the first mounting parts 21 are aligned in a first direction on the insulating plate 1, and the second mounting parts 31 are aligned in a first direction on the insulating plate 1.
That is, the first mounting portions 21 are arranged in a row on the insulating plate 1, and the second mounting portions 31 are arranged in another row on the insulating plate 1. The first mounting portions 21 of one row and the second mounting portions 31 of the other row are staggered with each other to prevent the first terminals 2 and the second terminals 3 from contacting each other to cause a short circuit.
In some embodiments, the displacement difference of the adjacent two first terminals 2 and second terminals 3 in the third direction is 0.5 mm.
In some embodiments, each first terminal 2 has a first intermediate portion 22 fixedly connected to the first mounting portion 21, and each second terminal 3 has a second intermediate portion 32 fixedly connected to the second mounting portion 31. The difference in height in the second direction between each first intermediate portion 22 and any one of the second intermediate portions 32 is greater than or equal to 2.5 times the thickness in the second direction of any one of the first intermediate portions 22.
Further, the plurality of first intermediate portions 22 are aligned in a line in the first direction on the insulating plate 1, and the plurality of second intermediate portions 32 are aligned in a line in the second direction on the insulating plate 1.
It can be understood that due to the limitation of the standard size of USB, the plurality of first terminals 2 and the plurality of second terminals 3 are staggered with each other, so that the signal transmission of the two first terminals 2 in the differential signal terminal pair is interfered by the control signal transmitted by the control terminal (the second terminal 3 located between the differential signal terminal pair), and the signals between the two first terminals 2 in the differential signal terminal pair cannot be coupled. When the height difference between the first middle portion 22 and any one of the second middle portions 32 in the second direction is greater than or equal to 2.5 times the thickness of any one of the first middle portions 22 in the second direction, the interference of the control terminal on the corresponding differential signal terminal pair can be effectively reduced, and at the moment, the first terminal and the second terminal are not easily broken down by current, so that the risk of short circuit is reduced. At the moment, the energy of the signals in the transmission process is concentrated on the inner surfaces of the positive and negative signals, so that coupling association is formed, a group of complete differential pair groups can be formed on the differential signal terminal pairs, and the differential signal terminal pairs have anti-interference capacity, so that high-speed data transmission is realized.
In some embodiments, the second intermediate portion 32 is half-wrapped embedded in the insulating plate 1, and at least a surface of a side of the second intermediate portion 32 facing away from the insulating plate 1 is exposed to air.
In some embodiments, each first terminal 2 has a first contact portion 23 fixedly connected to an end of the first middle portion 22 away from the connection side, and a vertical distance between each first contact portion 23 and the insulating plate 1 along the second direction is at least partially greater than a vertical distance between the corresponding first middle portion 22 and the insulating plate 1.
That is, the relative height of the first contact portion 23 to the insulating plate 1 is at least partially greater than the relative height of the first middle portion 22 to the insulating plate 1 (the first contact portion 23 protrudes toward the direction away from the insulating plate 1), so as to facilitate connection with a member to be connected, and further achieve signal transmission.
In some embodiments, the end of the first contact portion 23 remote from the first intermediate portion 22 is bent toward the side close to the insulating plate 1.
In some embodiments, each second terminal 3 has a second contact portion 33 fixedly connected to an end of the second middle portion 32 away from the connection side, and a vertical distance between each second contact portion 33 and the insulating plate 1 along the second direction is at least partially greater than a vertical distance between its corresponding second middle portion 32 and the insulating plate 1.
That is, the relative height of the second contact portion 33 to the insulating plate 1 is at least partially greater than the relative height of the second middle portion 32 to the insulating plate 1 (the second contact portion 33 protrudes in a direction away from the insulating plate 1), so as to facilitate connection with a member to be connected, and thus, signal transmission is realized.
In some embodiments, an end of the second contact portion 33 away from the second intermediate portion 32 is bent toward a side close to the insulating plate 1, and an end of the second contact portion 33 away from the second intermediate portion 32 is in contact with the insulating plate 1, and at least a side surface of the second contact portion 33 facing away from the insulating plate 1 is exposed to the air.
That is, the second contact portion 33 portion of the second terminal 3 is raised with respect to the insulating plate 1. The other part of the second contact portion 33 and the second intermediate portion 32 are embedded in the insulating plate 1 and are at least partially exposed to the air.
In some embodiments, the arrangement direction of the projections of the plurality of second contact portions 33 on the insulating plate 1 is parallel to the arrangement direction of the projections of the plurality of first contact portions 23 on the insulating plate 1, and the projections of the first contact portions 23 on the insulating plate 1 are closer to the connection side than the projections of the second contact portions 33 on the insulating plate 1.
That is, the length of any first terminal 2 in the third direction is smaller than the length of any second terminal 3 in the third direction, and the side of the second terminal 3 away from the second middle portion 32 is further prevented from contacting the first terminal 2 and causing a short circuit.
In some embodiments, the length of the first terminal 2 in the third direction is less than or equal to the sum of the length of the second middle portion 32 in the third direction and the length of the second mounting portion 31 in the third direction, so that the first contact portion 23 and the second contact portion 33 of the first terminal 2 and the second terminal 3 can be staggered with respect to each other, on one hand, contact short-circuit can be prevented, and on the other hand, the first terminal 2 and the second terminal 3 can be free from mutual interference.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present disclosure, and the present disclosure should be construed as being covered by the claims and the specification.
