[0047] Please refer to Figures 1 to 5, an embodiment of the present invention discloses a signal transmission base for anti-interference between signal terminals. The base 1 is used to connect to the base head 2 to achieve high-speed transmission of 5G signals. The base 1 includes: an independently provided signal shielding frame 11 for shielding external interference signals. A second grounding welding foot 113 is provided on the signal shielding frame 11. After the second grounding welding foot 113 is grounded, the signal shielding frame will form a protective cover outside, which can effectively shield external interference signals; a first group of signal terminals 12 and a second group of signal terminals 13 are arranged inside the signal shielding frame 11 to achieve high-speed transmission of 5G signals between the base head 2 and the base 1; independently provided first partition plate 14 and second partition plate 15 for shielding interference signals between the first group of signal terminals 12 and the second group of signal terminals 13; a base insulator 16 is located inside the signal shielding frame 11, and the first group of signal terminals 12, the second group of signal terminals 13, the first partition plate 14 and the second partition plate 15 are arranged on the base insulator 16.

[0048] In one embodiment, please refer to Figures 4 to 6 , the base 1 includes a first partition plate 14 and a second partition plate 15 for shielding interference signals between the first group of signal terminals 12 and the second group of signal terminals 13. The first partition plate 14 and the second partition plate 15 are separately arranged, and the first partition plate 14 and the second partition plate 15 are of the same processing technology. Therefore, only one of the partition plates with simple technology needs to be produced to meet the requirements of the present invention. Compared with the case where the first partition plate 14 and the second partition plate 15 are integrally arranged, the processing technology of the integral arrangement is complex. The partition plate is a symmetric structure, and the same structure needs to be repeatedly processed in the same processing technology, increasing the process difficulty and steps, which is extremely inconvenient. Obviously, in this embodiment, because the first partition plate 14 and the second partition plate 15 have the same structure, only repeated processing is needed to produce a partition plate that can effectively isolate the interference signals between the two groups of signal terminals. Further, both the first partition plate 14 and the second partition plate 15 are separately arranged from the signal shielding frame 11. In the existing connectors, generally the partition plate and the signal shielding frame 11 are integrally arranged. Because the structures of the two are relatively complex, although the integral arrangement can process some structures at one time, its process steps are relatively complex, which will increase the production difficulty and defective rate of the partition plate. Further, the first partition plate 14 and the second partition plate 15 are symmetrically arranged in the first direction between the first group of signal terminals 12 and the second group of signal terminals 13, and the area covered by the first partition plate 14 and the second partition plate 15 in the second direction is larger than the area of the first group of signal terminals 12 and the second group of signal terminals 13, that is, the projected area of the first group of signal terminals 12 and the second group of signal terminals 13 on the first partition plate 14 and the second partition plate 15 is smaller than the area of the first partition plate 14 and the second partition plate 15. After the two partition plates are grounded, the interference signals between the two groups of signal terminals can be effectively shielded.

[0049] In one embodiment, please refer toFigure 6 , both the first baffle 14 and the second baffle 15 include a partition arm 151, a first anti-collision arm 152, and a first grounding welding foot 153 arranged in sequence along the first direction. In this embodiment, the first baffle 14 and the second baffle 15 are in a linear structure, which is convenient both in the production and processing and in the use process; further, the first grounding welding foot 153 is located below the base fixing member 111 for convenient grounding. The base fixing member 111 is provided with holes for the first baffle 14 and the second baffle 15 to pass through, and the first grounding welding foot 153 extends out of the base fixing member 111 through these holes for grounding. This structure is relatively compact and is a preferred method. Especially in such a precision connector, the compact structure can save the occupied space of the connecting parts and make the electronic device more compact.

[0050] In one embodiment, please refer to Figures 7 to 9, the first anti-collision arm 152 is used to prevent the signal terminal from being damaged and avoid damage to the signal terminal during the insertion of the base head 2. It belongs to mechanical protection. The first anti-collision arm 152 includes a first bending portion 1521, a first connecting member 1522, a second bending portion 1523, a second connecting member 1524, and a third bending portion 1525. This structure has a relatively stable connection and can preferably arrange the isolation arm 151, the first anti-collision arm 152, and the first grounding welding foot 153 in a straight line along the first direction, which can save the internal space of the signal shielding frame 11 and make full use of this space to achieve the isolation effect. This is crucial for the precision connector for 5G high-speed signal transmission. Further, the isolation arm 151 forms a first end by opening a first through hole 1526 on the isolation arm 151, and the first anti-collision arm 152 forms a second end by opening a second through hole 1527 on the first anti-collision arm. The first through hole 1526 and the second through hole 1527 divide a part of the material at the end of the isolation arm 151, eliminating the need for an additional anti-collision arm. An additional anti-collision arm is not stable enough. By directly processing the first bending portion 1521 on the isolation arm 151, the connection between the first anti-collision arm 152 and the isolation arm 151 can be made more stable. Both the first through hole 1526 and the second through hole 1527 are semi-open structures, and the openings are on the isolation arm 151 along the positive direction of the third direction, making the processing easy and not complex. It can be understood that there are also various ways to form the first end. For example, the first end can be set on the side of the isolation arm 151 without opening the first through hole 1526, and the connection is still stable. Further, the first bending portion 1521 is bent from the first end along the second direction, and it can be bent either in the positive direction or in the negative direction, with no difference between the two. The second bending portion 1523 is bent from the first connecting member 1522 along the negative direction of the third direction. The direction of arrow X is the first direction, and the first direction is the length direction of the connector; the direction of arrow Y is the second direction, and the second direction is the width direction of the connector; the direction of arrow Z is the third direction, and the third direction is the vertical direction, that is, the height direction of the connector. The third direction is perpendicular to the first direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the third direction. This bending method sets the height of the first connecting member 1522 to exceed the heights of the first baffle 14 and the second baffle 15, thereby playing an anti-collision role and being able to preferably protect the signal terminal. The third bending portion 1525 is bent from the second connecting member 1524 along the positive or negative direction of the first direction. Further, the first bending portion 1521 includes a first guiding arc, and the second bending portion 1523 includes a second guiding arc. The guiding arcs play a transitional role. When the signal terminal on the base head 2 is connected to the signal terminal on the base 1, the guiding arcs can enable the two to be stably connected, reduce the wear between the two, and avoid damaging the signal terminal due to contact and affecting the transmission stability of the connector.Furthermore, along the positive direction of the third direction, the position of the first connecting member 1522 is higher than the positions of the first group of signal terminals 12 and the second group of signal terminals 13. The first connecting member 1522 can play a positioning role. When the base head 2 contacts the first connecting member 1522, the base head 2 cannot move down further, avoiding over-insertion and damaging the signal terminals.

[0051] In one embodiment, please refer to Figure 10 , the first blocking partition 14 and the second blocking partition 15 are embedded in the base insulator 16. The embedded connection is more stable and can prevent the first blocking partition 14 and the second blocking partition 15 from loosening. Furthermore, the first blocking partition 14 and the second blocking partition 15 further include a third connecting member 154 and a fourth bending portion 155. The third connecting member 154 is connected to the first anti-collision arm 152. The third connecting member 154 and the first grounding welding foot 153 are connected through the fourth bending portion 155. The fourth bending portion 155 is formed by bending the third connecting member 154 along the negative direction of the third direction. In this embodiment, the second connecting member 1524, the third bending portion 1525, the third connecting member 154, and the fourth bending portion 155 together form a folded structure. One end of the folded structure is connected to the first anti-collision arm 152, and the opposite end of the folded structure is connected to the first grounding welding foot 153, facilitating grounding of the first blocking partition 14 and the second blocking partition 15. Moreover, the middle part of the folded structure is a plate, and the whole plate is embedded in the base insulator 16, which can effectively fix the positions of the first blocking partition 14 and the second blocking partition 15. Compared with a non-embedded structure, for example, the first grounding welding foot 153 and the third connecting member 154 are integrally provided, where a part of the third connecting member 154 is fixedly connected to the base insulator 16, and the other part is exposed to the external environment without a support structure. If the first grounding welding foot 153 is collided, it is very likely to bend or even damage the first grounding welding foot 153 and the third connecting member 154. As an improvement of this embodiment, the second connecting member 1524 and the third bending portion 1525 can be omitted, and the third connecting member 154 is directly connected to the first anti-collision arm 152 and the first grounding welding foot 153. At this time, the second connecting member 1524 is no longer horizontally arranged but in an inclined state, and it can still be embedded in the base insulator 16, and the connection is relatively stable.

[0052] In one embodiment, please refer to Figure 11, the signal shielding frame 11 is sleeved on the base insulator 16. The signal shielding frame 11 includes base fixing members 111 and connecting arms 112. There are two base fixing members 111 and two connecting arms 112. The two base fixing members 111 are arranged at opposite ends of the signal shielding frame 11 along the first direction, and the two connecting arms 112 are arranged at opposite ends of the signal shielding frame 11 along the second direction. The base fixing members 111 and the connecting arms 112 are connected to each other in pairs to form the signal shielding frame 11. Specifically, the connection method is: base fixing member - connecting arm - base fixing member - connecting arm - base fixing member. Moreover, the signal shielding frame 11 is integrally formed. Multiple second grounding welding feet 113 are provided at the lower parts of the two connecting arms 112. The multiple second grounding welding feet 113 are equally spaced along the length direction of the connecting arms 112, i.e., the first direction. The multiple second grounding welding feet are grounded to enable the signal shielding frame 11 to shield external interference signals. Shielding interference signals by grounding is a prior art, and this application will not elaborate on it.

[0053] In one embodiment, please refer to Figure 11, a second anti-collision arm 1121 is provided on the connecting arm 112. There are at least 3 pairs of the second anti-collision arms 1121, which are evenly arranged in the middle and at both ends of the connecting arm 112. In this embodiment, the number of pairs of the second anti-collision arms 1121 is 3 pairs, and one pair has 2 pieces. From the perspective of the two connecting arms 112, the two second anti-collision arms 1121 of each pair are respectively arranged on the two connecting arms 112, and their positions correspond to each other and are symmetrically arranged, so the installation stability is better. If the positions are set randomly, when the base head 2 and the base 1 are inserted and pulled out, the respective connection ends of the two will not be inserted or pulled out synchronously, which will have certain negative impacts. For example, the second anti-collision arm 1121 on one connecting arm 112 is close to the end, and the second anti-collision arm 1121 on the other connecting arm 112 is closer to the middle of the connecting arm 112. Then when inserting the base head 2, the second anti-collision arm 1121 closer to the middle cannot stably support the pressure applied by humans. On the part of this connecting arm 112 close to the end, the base head 2 may tilt under the human pressure and be inserted into the base 1 in advance, while the part of the other connecting arm 112 close to the end is still supported by the second anti-collision arm 1121. Then the tilted part of the base head 2 may collide with the base 1, which will damage the connector itself. If the insertion and extraction are carried out according to this embodiment, each contact point between the base head 2 and the base 1 is synchronous and no tilting condition will occur, and the insertion and extraction actions will be more stable. Further, from the perspective of a single connecting arm 112, three second anti-collision arms 1121 are provided on each connecting arm 112, which are respectively located at both ends and in the middle of the connecting arm 112, and the installation stability is better. If the second anti-collision arm 1121 is not provided in the middle of the connecting arm 112, the base head 2 may be damaged under external pressure. For example, only the second anti-collision arms 1121 are provided at both ends of the base 1. When inserting the base head 2 into the base 1, the pressure from the external environment usually acts on the middle of the base head 2, and there is no support point in the middle of the base 1 either. If the pressure is large, the middle of the base head 2 may bend or even break. However, this problem will not occur with the three second anti-collision arms 1121 of this embodiment. The second anti-collision arm 1121 in the middle will bear the external pressure and insert the base head 2 into the base 1 stably through this second anti-collision arm 1121. This embodiment has some alternative solutions. For example, the second anti-collision arms 1121 are provided at both ends of one connecting arm 112, and the second anti-collision arm 1121 is provided in the middle of the other connecting arm 112.

[0054] Furthermore, the second anti-collision arm 1121 includes a fifth bending portion 11211, a sixth bending portion 11213, a fourth connecting member 11212, and a fifth connecting member 11214. The fifth bending portion 11211 and the sixth bending portion 11213 have certain bends, which have a certain transitional effect when inserting and removing the base head 2, and can smoothly insert and remove the base head 2. The fourth connecting member 11212 can play a positioning role. When the base head 2 is slowly inserted into the base 1, it will eventually come into contact with the fourth connecting member 11212. The position of the fourth connecting member 11212 is a pre-set position calculated in advance. After the base head 2 contacts the fourth connecting member 11212, it will no longer move, which can effectively prevent the base head 2 from being inserted too far and damaging the signal terminals. Further, the fifth bending portion 11211 is connected to the base fixing member 111. The fifth bending portion 11211 and the sixth bending portion 11213 are connected by the fourth connecting member 11212, and the fifth connecting member 11214 is connected to the sixth bending portion 11213, which can effectively prevent the base head 2 from hitting the signal terminals. Furthermore, the fifth bending portion 11211 is formed by bending the base fixing member 111 along the positive direction of the second direction, and the sixth bending portion 11213 is formed by bending the fourth connecting member 11212 along the negative direction of the third direction. In fact, in this embodiment, the bending directions of the fifth bending portion 11211 and the sixth bending portion 11213 are towards the shielding partition, that is, the center of the signal shielding frame 11, so that the internal space of the signal shielding frame 11 can be fully utilized. Furthermore, the fifth bending portion 11211 includes a third guiding arc, and the sixth bending portion 11213 includes a fourth guiding arc. The circular arc structure has better stability and can better insert the base head 2 into the base 1, reducing the wear caused by contact between the base head 2 and the base 1.

[0055] In one embodiment, please refer to Figures 1 to 5, in the positive direction of the third direction, the position of the fourth connecting member 11212 is higher than the positions of the first set of signal terminals 12, the second set of signal terminals 13, the first blocking partition 14, and the second blocking partition 15. The purpose is to limit the base head 2 to prevent over-insertion and damage to the connector. In another embodiment, it can be understood that the fourth connecting member 11212 can also be a groove structure. In this case, a boss matching the groove is provided on the base head 2. After the base head 2 is inserted into the base 1, the boss can cooperate with the groove to limit the base head 2. The use of the groove-boss matching method is only to make the connection between the base head 2 and the base 1 more stable. Further, in the direction along the second direction and facing the blocking partition from the connecting arm 112, the position of the fifth connecting member 11214 is higher than the positions of the first set of signal terminals 12 and the second set of signal terminals 13. In essence, in this embodiment, the distance between the fifth connecting members 11214 of each pair of second anti-collision arms 1121 is less than the distance between the corresponding two signal terminals at this position, and the distance between the two signal terminals accommodates the distance between the two fifth connecting members 11214. In this way, when the base head 2 is inserted into the base 1, contact between the base head 2 and the signal terminals can be completely avoided, preventing damage to the signal terminals during the insertion and extraction of the base head 2.

[0056] In one embodiment, please refer to Figure 4 and Figure 12 , the base 1 includes a first set of signal terminals 12 and a second set of signal terminals 13, which are arranged in the signal shielding frame 11 and used for connecting to the circuit board. Both the first set of signal terminals 12 and the second set of signal terminals 13 include a plurality of first sub-terminals 121 and second sub-terminals 122. The first sub-terminals 121 are connected to the ground terminal of the circuit board, and the second sub-terminals 122 are connected to the signal transmission terminal of the circuit board. The first sub-terminals 121 and the second sub-terminals 122 have the same structure. The first sub-terminals 121 and the second sub-terminals 122 are alternately and spaced apart along the first direction, and the spacing is equally spaced. The specific setting method is: first sub-terminal → second sub-terminal → first sub-terminal → second sub-terminal... The second sub-terminals 122 are used to shield the interference signals between the first sub-terminals 121. The second sub-terminals 122 are grounded and arranged between two first sub-terminals 121, which can effectively shield the interference signals between the two first sub-terminals 121.

[0057] Further, please refer to Figure 13 and Figure 14, both the first sub-terminal 121 and the second sub-terminal 122 include a fixing portion 1211, an abutting portion 1212, and an elastic arm 1213 that are sequentially arranged in the positive or negative direction of the second direction. The positive direction of the second direction is the direction in which the first sub-terminal 121 and the second sub-terminal 122 on the first group of signal terminals 12 face the first baffle 14 and the second baffle 15 in the middle. The negative direction of the second direction is the direction in which the first sub-terminal 121 and the second sub-terminal 122 on the second group of signal terminals 13 face the first baffle 14 and the second baffle 15 in the middle. And the fixing portion 1211, the abutting portion 1212, and the elastic arm 1213 are integrally provided. The abutting portion 1212 abuts against the base head 2. The abutting portion 1212, the elastic arm 1213, and the fixing portion 1211 form a U-shaped structure. The abutting portion 1212 is the bottom of the U-shaped structure. When the signal terminal of the base head 2 is inserted into the base 1, it will contact the abutting portion 1212, thereby completing the installation of the base head 2 on the base 1. Moreover, the abutting portion 1212 is formed by bending the material of the fixing portion in the positive or negative direction of the second direction.

[0058] In one embodiment, please refer to Figure 13 and Figure 14 , the fixing portion 1211 of the first sub-terminal 121 is connected with a first welding portion 1214, and the fixing portion 1211 of the second sub-terminal 122 is connected with a second welding portion 1221. The first sub-terminal 121 is electrically connected to the signal transmission end on the circuit board, and the second sub-terminal 122 is electrically connected to the grounding end on the circuit board. Thus, the first sub-terminal 121 becomes a signal transmission terminal for transmitting signals, and the second sub-terminal 122 becomes a grounding terminal for shielding the interference signals between the first sub-terminals 121.

[0059] In another embodiment, which is an improvement of the previous embodiment, the first sub-terminal and the second sub-terminal have the same structure. Both the first sub-terminal and the second sub-terminal include two wiring states, and can be grounded or connected to the signal input line, and the wiring states of both can be switched arbitrarily. Further, the first sub-terminal and the second sub-terminal are alternately and spaced apart along the first direction, and the spacing is equally spaced. The specific setting method is as follows: first sub-terminal → second sub-terminal → first sub-terminal → second sub-terminal... Both the first sub-terminal and the second sub-terminal include a fixing portion, an abutting portion, an elastic arm, and a third welding portion (not shown). Each first sub-terminal and second sub-terminal corresponds to two wiring terminals in the circuit, and the two wiring terminals are respectively a grounding terminal and a signal transmission terminal. During normal use, the signal terminals are arranged as follows: the third welding portion of the first sub-terminal is connected to the grounding terminal → the third welding portion of the second sub-terminal is connected to the signal transmission terminal → the third welding portion of the first sub-terminal is connected to the grounding terminal → the third welding portion of the second sub-terminal is connected to the signal transmission section... When one of the signal terminals fails, for example, one of the first sub-terminals connected to the grounding terminal fails, the arrangement of the signal terminals is as follows: the third welding portion of the first sub-terminal is connected to the grounding terminal → the third welding portion of the second sub-terminal is connected to the signal transmission terminal → the third welding portion of the first sub-terminal is connected to the grounding terminal (failed) → the third welding portion of the second sub-terminal is connected to the signal transmission terminal... Then, there will be a situation where two second sub-terminals connected to the signal transmission end are adjacent. Since the grounding first sub-terminal between them fails and cannot be used normally, the interference signal between them cannot be shielded. During the high-speed transmission of 5G signals, this will greatly affect the transmission speed of 5G signals, thereby affecting the normal use of 5G devices. Therefore, the present invention proposes this embodiment. By using the first sub-terminal and the second sub-terminal provided in this embodiment, when the grounding terminal fails, the wiring state of the signal terminal after the failed grounding terminal can be switched. For example: the third welding portion of the first sub-terminal is connected to the grounding terminal → the third welding portion of the second sub-terminal is connected to the signal transmission terminal → the third welding portion of the first sub-terminal is connected to the grounding terminal (failed) → the third welding portion of the second sub-terminal is connected to the grounding terminal → the third welding portion of the first sub-terminal is connected to the signal transmission terminal → the third welding portion of the second sub-terminal is connected to the grounding terminal... In this way, it is possible to avoid the situation where there is no grounding terminal between two signal terminals connected to the signal transmission. It can be understood that there are many other state conversion optimization methods, which will not be exemplified one by one here. The connector of this embodiment can be recycled, has good use performance, is not easily scrapped, saves costs, is convenient to use, and can better meet the requirements of high-speed transmission of 5G signals.

[0060] As an improvement over the previous embodiment, an indicator light can be provided on the signal terminal wiring loop. When the third grounding solder pad of the signal terminal is connected to the grounding end, the indicator light displays a first color. When the third grounding solder pad of the signal terminal is connected to the signal transmission end, the indicator light displays a second color.

[0061] In one embodiment, please refer to Figure 13 and Figure 14 , a first accommodation cavity 12111 is provided in the fixing part 1211. The first accommodation cavity 12111 is used to connect with the base insulator 16. Pouring the base insulator into this first accommodation cavity will make the connection of the signal terminal more stable. Further, a first guiding part 12112 is provided on the fixing part 1211. The first guiding part 12112 faces the elastic arm 1213. The first guiding part 12112 is used to guide the signal terminal of the base head 2, and the first guiding part 12112 is used in cooperation with the elastic arm 1213. Further still, the first guiding part 12112 is an arc-shaped convex structure. The convex structure can stably support the signal terminal of the base head, and the arc-shaped structure can more stably guide the signal terminal of the base head 2.

[0062] In one embodiment, please refer to Figure 15 , a second accommodation cavity 161 is provided on the base insulator 16. The second accommodation cavity 161 is used to accommodate the elastic arm 1213. The second accommodation cavity 161 is a hollow structure. The elastic arm 1213 is formed by bending the material of the abutting part 1212 along the positive direction of the third direction. A second guiding part 12131 is provided on the elastic arm 1213. The second guiding part 12131 is used to guide the base head 2. The elastic arm 1213 is made of elastic material, and the distance between the first guiding part 12112 and the second guiding part 12131 is less than the width of the signal terminal of the base head 2 between the two. Due to the elasticity of the elastic arm 1213, when the base head 2 is inserted, the signal terminal of the base head 2 will contact the first guiding part 12112 and the second guiding part 12131, and as the two guiding parts gradually move downward, the distance between the first guiding part 12112 and the second guiding part 12131 slowly becomes larger until the simple distance between the two is equal to the width of the signal terminal of the base head 2. At this time, the base head 2 continues to move downward until the signal terminal of the base head 2 abuts against the abutting part 1212, and the installation of the base 1 of the base head 2 is completed.

[0063] In one embodiment, please refer to Figure 4 , the base 1 further includes a base insulator 16, which is arranged in the signal shielding frame 11 and surrounds the first group of signal terminals 12, the second group of signal terminals 13, the first baffle 14 and the second baffle 15. The signal shielding frame 11, the first group of signal terminals 12, the second group of signal terminals 13, the first baffle 14 and the second baffle 15 are cast as a whole, and the cast part forms the base insulator 16, and the connection between the various structures is relatively stable.

[0064] In one embodiment, auxiliary tape connection ends for rapid production are provided on both the first grounding pin 153 and the signal shielding frame 11. A base fixing member 111 or the first grounding pin 153 can be connected to an auxiliary tape connection arm on the auxiliary tape through the auxiliary tape connection end. A number of auxiliary tape connection arms are provided on the upper side of the auxiliary tape, and the number of auxiliary tape connection arms are arranged at equal intervals along the length direction of the auxiliary tape. Each auxiliary tape connection arm is connected to a base fixing member 111 or the first grounding pin 153. A number of rack tooth-shaped openings are provided on the lower side of the auxiliary tape, and the number of rack tooth-shaped openings are arranged at equal intervals along the length direction of the auxiliary tape. After such a setting, the auxiliary tape is driven to move linearly by a gear. After the processing of the previous base fixing member 111 or the first grounding pin 153 is completed, the gear rotates one tooth, and then the next base fixing member 111 or the first grounding pin 153 is processed. Such a cycle realizes the high-speed mass production of the base 1 in a pipeline manner. With the structure of the base fixing member 111 or the first grounding pin 153 in this embodiment, 500 bases 1 can be produced per minute.

[0065] In a second aspect, an embodiment of the present invention discloses a connector, including the signal transmission base for preventing interference between signal terminals described above.

[0066] With the above structure for the connector in the embodiment of the present invention, during the connection process between the base head 2 and the base 1, the first anti-collision arm 152 of the base fixing member 111 first contacts the anti-collision arm of the base head 2. Then, the first introduction part 12112 of the fixing part 1211 on the signal terminal of the base 1 and the second introduction part 12131 on the elastic arm 1213 are in contact with the corresponding parts on the signal terminal of the base head 2, and the base head 2 is gradually pressed down. When the signal terminal of the base head 2 abuts against the abutting part 1212, the base head 2 is simultaneously in contact connection with the first connecting member 1522, the second connecting member 1524, the fourth connecting member 11212, and the fifth connecting member 11214, realizing the signal transmission between the base head 2 and the base 1. A welding pad PAD is provided on the base head 2, and the welding pad is used to accommodate solder (solder paste), which is convenient for base head chip mounting.

[0067] In a third aspect, an embodiment of the present invention discloses an electronic device, including the signal transmission base for preventing interference between signal terminals or the connector described above.

[0068] In the electronic device according to the embodiment of the present invention, adopting the above structure, during the connection process of the base head 2 and the base 1, the first anti-collision arm 152 of the base fixing member 111 first contacts the anti-collision arm of the base head 2, and then the first guiding portion 12112 of the fixing portion 1211 on the signal terminal of the base 1 and the second guiding portion 12131 on the elastic arm 1213 are in contact with the corresponding ones on the signal terminal of the base head 2. Then, the base head 2 is gradually pressed down. When the signal terminal of the base head 2 abuts against the abutting portion 1212, the base head 2 is simultaneously in contact connection with the first connecting member 1522, the second connecting member 1524, the fourth connecting member 11212, and the fifth connecting member 11214, realizing signal transmission between the base head 2 and the base 1. A welding pad PAD is provided on the base head 2, and the welding pad is used to accommodate solder (solder paste) to facilitate the base head patch.
