At present, the TYPEC connection structure is a commonly used multi-pin connection solution. Its connection terminal has a total of 24 pins, including 12 pins in each of the upper and lower rows. Designers can define different pins to realize multiple functions.

[0003] At present, the single-line contact scheme of TYPEC connection structure is as follows Figure 1 As shown, the interface pin is straight, and the terminal pin is provided with an arc-shaped bending portion at a position away from the terminal base.

DETAILED DESCRIPTION

[0022] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0024] Figure 1 It is a schematic diagram of the matching structure of the connection terminal and the connection interface in the prior art.

[0025] The TYPEC connection structure is a commonly used multi-pin connection scheme. Its connection terminal has a total of 24 pins, including 12 pins in each of the upper and lower rows. Designers can define different pins to achieve multiple functions. Figure 1 As shown, the interface pin 201 is straight, and the terminal pin is provided with an arc-shaped bending portion at a position away from the terminal base. When the connection terminal 1 is plugged into the connection interface 2, the arc-shaped bending portion of the terminal pin abuts against the corresponding interface pin 201. The inventor of the present application has found through research that the contact form between the terminal pin and the corresponding interface pin in the prior art is close to line contact, and the contact area is small, which is very likely to cause poor contact, thereby causing functional failure due to poor signal transmission, which is manifested as failure to recognize the inserted device.

[0026] In order to solve the problems in the prior art, the present application provides a connection terminal and a data line, which are described in detail below with reference to the accompanying drawings.

[0028] Figure 3 A schematic diagram of the internal structure of the connection terminal provided in an embodiment of the present application.

[0029] See also Figures 2 to 3The embodiment of the present application provides a connection terminal 1, including a terminal base 102, a terminal housing and a terminal pin 101. One end of the terminal housing along the first direction X is fixedly connected to the terminal base 102, and the other end is provided with an insertion interface 104. The terminal housing includes a first side wall 103 parallel to the first direction X; the terminal pin 101 includes a lead-out section 1011, a first support section, a butt section 1014 and a second support section located in the terminal housing and distributed successively along the first direction X. Part of the lead-out section 1011 is fixedly connected to the terminal base 102, the butt section 1014 is parallel to the first side wall 103, and the first support section and the second support section both butt against the first side wall 103, so as to provide a supporting force to the butt section 1014 to press against the interface pin 201 when the connection terminal 1 is plugged into the connection interface 2.

[0030] During the process of the terminal housing being plugged into the connection interface 2, the interface pin 201 in the connection interface 2 can be inserted into the plug-in port 104 and abutted against the abutting section 1014. The first supporting section cooperates with the second supporting section to provide supporting force to the abutting section 1014, so that when the connection terminal 1 is plugged into the connection interface 2, the terminal pin 101 can stably abut against the interface pin 201. At the same time, since the abutting section 1014 is parallel to the first side wall 103, when the connection terminal 1 is plugged into the connection interface 2, a surface contact can be formed between the terminal pin 101 and the interface pin 201, achieving a relatively large contact area, thereby enabling the terminal pin 101 to form good contact with the interface pin 201 and stably realize data and signal transmission, thereby reducing the risk of functional failures such as failure to recognize the inserted device due to poor contact.

[0031] like Figure 3 As shown, in some embodiments, the first supporting section includes a first branch section 1012 and a second branch section 1013 distributed successively along the first direction X, the first branch section 1012 is connected to the lead-out section 1011, the second branch section 1013 is connected to the supporting section 1014, and the connecting position of the first branch section 1012 and the second branch section 1013 abuts against the first side wall 103. When the connecting terminal 1 is plugged into the connecting interface 2, the interface pin 201 and the terminal pin 101 are tightly abutted. Compared with the state where the connecting terminal 1 is not plugged into the connecting interface 2, the supporting section 1014 will produce a slight displacement in the direction close to the corresponding first side wall 103. At the same time, the first supporting section and the second supporting section will provide a supporting force to the supporting section 1014 to press the interface pin 201. By limiting the connecting position of the first branch section 1012 and the second branch section 1013 to abut against the first side wall 103, it can be prevented that the connecting position of the supporting section 1014 and the second branch section 1013 is prevented from tilting toward the direction close to the corresponding first side wall 103 due to excessive supporting force provided by the second supporting section to the supporting section 1014, thereby further improving the contact stability between the supporting section 1014 and the interface pin 201.

[0032] like Figure 3 As shown, in some embodiments, the angle between the first branch segment 1012 and the second branch segment 1013 at the joint position is greater than or equal to 90°. It should be noted that the above definition means that when the connection terminal 1 is in a natural state without being plugged into the connection interface 2, the angle between the first branch segment 1012 and the second branch segment 1013 at the joint position is greater than or equal to 90°. During the process of repeatedly plugging and unplugging the connection terminal 1 relative to the connection interface 2, the abutting segment 1014 will repeatedly move slightly in a direction perpendicular to the first side wall 103. Since the joint position between the first branch segment 1012 and the second branch segment 1013 abuts against the first side wall 103, the angle between the second branch segment 1013 and the first branch segment 1012 will also repeatedly increase and decrease. In the natural state, the smaller the included angle between the first branch section 1012 and the second branch section 1013 is, the greater the change in the included angle between the first branch section 1012 and the second branch section 1013 is when the abutting section 1014 undergoes the same displacement in the direction perpendicular to the first side wall 103, and the metal fatigue is more likely to occur at the connecting position of the first branch section 1012 and the second branch section 1013. Therefore, by limiting the included angle between the first branch section 1012 and the second branch section 1013 to be greater than or equal to 90°, it is possible to prevent the metal fatigue from occurring too early at the connecting position of the first branch section 1012 and the second branch section 1013 due to the too small included angle between the first branch section 1012 and the second branch section 1013, and the working life of the first supporting section can be relatively increased.

[0033] like Figure 3 As shown, in some embodiments, the angle between the lead-out section 1011 and the first branch section 1012 and the angle between the second branch section 1013 and the abutting section 1014 are both obtuse angles. It should be noted that the above definition means that when the connection terminal 1 is in a natural state without being plugged into the connection interface 2, the angle between the lead-out section 1011 and the first branch section 1012 and the angle between the second branch section 1013 and the abutting section 1014 are both obtuse angles, which avoids the metal fatigue caused by the angle at the corresponding position being too small, and can relatively increase the working life of the corresponding position.

[0034] like Figure 3 As shown, in some embodiments, the lead-out section 1011 is parallel to the first side wall 103, the distance from the lead-out section 1011 to the first side wall 103 is smaller than the distance from the abutting section 1014 to the first side wall 103, the length of the lead-out section 1011 along the first direction X is generally shorter, and under the premise that the length of the lead-out section 1011 remains unchanged, by limiting the distance between the lead-out section 1011 and the first side wall 103 to be relatively small, the angle between the lead-out section 1011 and the first branch section 1012 and the angle between the first branch section 1012 and the second branch section 1013 can be made relatively large, thereby preventing metal fatigue from occurring prematurely at the corresponding position and improving the service life of the corresponding position.

[0035] like Figure 3As shown, in some embodiments, the second support segment includes a third branch segment 1015 and a fourth branch segment 1016 distributed successively along the first direction X, the fourth branch segment 1016 is parallel to the first side wall 103, and the side of the fourth branch segment 1016 facing the first side wall 103 abuts against the first side wall 103. During the process of repeated plugging and unplugging of the connecting terminal 1 relative to the connecting interface 2, there is an interaction force perpendicular to the first side wall 103 between the second support segment and the corresponding first side wall 103, and the contact position of the second support segment and the corresponding first side wall 103 will move repeatedly along the first direction X. By setting the fourth branch segment 1016, the contact area of ​​the corresponding position can be increased to avoid large wear caused by too small contact area at the corresponding position.

[0036] like Figure 3 As shown, in some embodiments, the angle between the third branch segment 1015 and the abutting segment 1014 is an obtuse angle. It should be noted that the above definition means that when the connection terminal 1 is in a natural state without being plugged into the connection interface 2, the angle between the third branch segment 1015 and the abutting segment 1014 is an obtuse angle, which avoids the metal fatigue at the corresponding position due to the angle being too small, and can relatively improve the service life of the corresponding position. In addition, during the process of plugging the connection terminal 1 into the connection interface 2, the third branch segment 1015 can play a certain guiding role on the interface pin 201, so that the interface pin 201 can smoothly abut against the abutting segment 1014.

[0037] like Figure 3 As shown, in some embodiments, the length of the fourth branch segment 1016 along the first direction X is H1, satisfying 0.1mm≤H1≤0.15mm. By limiting the minimum value, the contact position between the second support segment and the corresponding first side wall 103 can be prevented from prematurely experiencing significant wear. By limiting the maximum value, the risk of leakage caused by the fourth branch segment 1016 being too long and extending out of the plug interface 104 can be reduced.

[0038] Figure 4 for Figure 3 Schematic diagram of the structure in the A direction.

[0039] like Figure 3 and Figure 4As shown, in some embodiments, the length of the abutting section 1014 along the first direction X is H2, which satisfies 0.61mm≤H2≤1.01mm, and the width of the abutting section 1014 along the second direction Y is H3, which satisfies 0.14mm≤H3≤0.245mm, and the second direction Y is parallel to the first side wall 103 and perpendicular to the first direction X. By limiting the minimum values ​​of H2 and H3, it is ensured that the abutting section 1014 and the interface pin 201 have sufficient contact area, so that good contact can be formed between the two, and data and signal transmission can be stably achieved; by limiting the maximum value of H2, the risk of leakage caused by the fourth branch section 1016 extending out of the plug interface 104 due to the excessive length of the abutting section 1014 can be reduced; by limiting the maximum value of H3, under the premise that the connection terminal 1 has a fixed size along the second direction Y, the number of connection pins that can be arranged is increased.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, the terminal housing includes two first side walls 103 arranged opposite to each other along the third direction Z, and the area between the two first side walls 103 is provided with a plurality of pin groups spaced apart along the second direction Y, each pin group includes two terminal pins 101 arranged opposite to each other along the third direction Z, and the two terminal pins 101 included in each pin group are respectively abutted against the corresponding first side wall 103, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Specifically, in this embodiment, the terminal housing also includes two second side walls 105 arranged opposite to each other along the second direction Y, and the two edges of each second side wall 105 parallel to the first direction X are connected to the edge of the corresponding first side wall 103. By setting multiple pins, designers can define different terminal pins 101 to achieve multiple functions.

[0041] The present application also provides a data line, including the connection terminal 1 in the above embodiment. Since the connection terminal 1 includes the data line in the above embodiment, it has at least all the beneficial effects brought by the above embodiment, which will not be described one by one here.

[0042] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
