[0052] like Figure 1 and Figure 2 As shown, embodiment 2 of the present invention discloses a connector, which includes a base head 1 and a base 2 connected to each other, and the base head 1 is located on the upper part of the base 2; Figure 3 and Figure 4 As shown, the base head 1 includes a base head insulator 11, two base head fixing bodies, a plurality of first base head signal terminals 13, a plurality of second base head signal terminals 14, a plurality of third base head signal terminals 15 and a plurality of fourth base head signal terminals 16.

The first base rib 112 and the second base rib 113 are respectively arranged at the two ends of the base substrate 111. The first base rib 112 and the second base rib 113 are arranged parallel to each other. The third base rib 114 and the fourth base rib 115 are arranged between the first base rib 112 and the second base rib 113, and the third base rib 114 and the fourth base rib 115 are perpendicular to the first base rib 112.

[0053] The two base head fixing bodies are respectively installed at both ends of the base head insulator 11, specifically, one of the base head fixing bodies is installed on the first base head rib 112, and the other base head fixing body is installed on the second base head rib 113. Figure 5As shown, the base head fixing body includes a first base head fixing portion 121 and two second base head fixing portions 122 symmetrically arranged about the centerline of the first base head fixing portion 121. The second base head fixing portions 122 are arranged perpendicular to the first base head fixing portion 121 and are integrally formed with the first base head fixing portion 121. A first lead-in arc 1214 is provided on the side of the first base head fixing portion 121 facing away from the first base head groove 116. The first lead-in arc 1214 extends away from the base and is connected to the fifth base head weld leg 1211, the sixth base head weld leg 1212, and the seventh base head weld leg 1213. A second lead-in arc 1221 is provided on the side of the second base head fixing portion 122 facing the first base head groove 116, and a third lead-in arc 1222 is provided on the side of the second base head fixing portion 122 facing away from the first base head groove 116.

[0054] like Figure 3 As shown, a plurality of first base head signal terminals 13 are mounted on the fourth base head rib 115, and a plurality of second base head signal terminals 14 are also mounted on the fourth base head rib 115. In this embodiment, the number of first base head signal terminals 13 is the same as the number of second base head signal terminals 14, and the first base head signal terminals 13 and the second base head signal terminals 14 are staggered and spaced apart along the length of the base head insulator 11. A plurality of third base head signal terminals 15 are mounted on the third base head rib 114, and a plurality of fourth base head signal terminals 16 are also mounted on the third base head rib 114. In this embodiment, the number of third base head signal terminals 15 is the same as the number of fourth base head signal terminals 16, and the third base head signal terminals 15 and the fourth base head signal terminals 16 are staggered and spaced apart along the length of the base head insulator 11. Furthermore, in this embodiment, the number of first base head signal terminals 13 is the same as the number of third base head signal terminals 15.

[0055] like Figure 6 and Figure 7 As shown, in this embodiment, the first base head signal terminal 13 is provided with a first connection groove 131 and a second connection groove 132, and the first connection groove 131 and the second connection groove 132 are respectively provided on opposite sides of the first base head signal terminal 13. At the same time, the first base head signal terminal 13 is also provided with a first base head welding foot 133, and the first base head welding foot 133 extends to the outside of the base head insulator 11. Figure 6 and Figure 7As shown, the second base head signal terminal 14 is provided with a first base head connecting arm 146, a second base head connecting arm 147, and a second base head welding foot 145. A third connecting protrusion 143 is provided on the side of the first base head connecting arm 146 facing the second base head connecting arm 147, and a third connecting contact 141 is provided on the side of the first base head connecting arm 146 facing away from the second base head connecting arm 147; a fourth connecting protrusion 144 is provided on the side of the second base head connecting arm 147 facing the first base head connecting arm 146, and a fourth connecting contact 142 is provided on the side of the second base head connecting arm 147 facing away from the first base head connecting arm 146. Figure 8 As shown, the second base head solder leg 145 on the second base head signal terminal 14 extends into the first base head groove 116. The first base head solder leg 133 extends to the outside of the base head insulator 11, while the second base head solder leg 145 extends into the first base head groove 116. This increases the distance between the first base head solder leg 133 and the second base head solder leg 145, preventing the solder ball on the first base head solder leg 133 from connecting with the solder ball on the second base head solder leg 145 during soldering, which could cause a short circuit between the first base head signal terminal 13 and the second base head signal terminal 14. In this embodiment, the structure of the third base head signal terminal 15 is the same as that of the first base head signal terminal 13. Specifically, the third base head signal terminal 15 is provided with a fifth connecting groove and a sixth connecting groove, which are respectively located on opposite sides of the third base head signal terminal 15.

The fourth base head welding leg 163 on the fourth base head signal terminal 16 extends into the interior of the first base head groove 116. The third base head welding pin extends to the outside of the base head insulator 11, and the fourth base head welding pin 163 extends to the inside of the first base head groove 116, thereby increasing the distance between the third base head welding pin and the fourth base head welding pin 163, avoiding the solder ball on the third base head welding pin from being connected to the solder ball of the fourth base head welding pin 163 during welding, resulting in a short circuit between the third base head signal terminal 15 and the fourth base head signal terminal 16.

[0056] like Figure 8As shown, the fourth base head rib 115 is provided with a first connecting block 1151 opposite to each second base head signal terminal 14. The first connecting block 1151 is an inverted T-shaped structure. The second base head signal terminal 14 is inserted into the base head insulator 11 from the side of the base head insulator 11 away from the base, so that the third connecting protrusion 143 and the fourth connecting protrusion 144 on the second base head signal terminal 14 are clamped on the first connecting block 1151.

The fourth base head signal terminal 16 is inserted into the base head insulator 11 from the side of the base head insulator 11 away from the base, so that the seventh and eighth connecting protrusions on the fourth base head signal terminal 16 are snap-fitted to the second connecting block, thereby connecting the second base head signal terminal 14 to the base head insulator 11. In this embodiment, the first base head signal terminal 13 and the third base head signal terminal 15 are embedded in the base head insulator 11.

[0057] like Figure 9 and Figure 10 As shown, the base 2 includes a base insulator 21, two base fixing bodies, a plurality of first base signal terminals 23, a plurality of second base signal terminals 24, a plurality of third base signal terminals 25 and a plurality of fourth base signal terminals 26.

When the base is connected to the base head, the boss 216 is embedded in the first base head groove 116. The boss 216 is arranged parallel to the third base rib 214 and between the third base rib 214 and the fourth base rib 215, so that a first base groove 217 is formed between the boss 216 and the third base rib 214. The size of the first base groove 217 matches the size of the fourth base head rib 115. When the base is connected to the base head, the fourth base head rib 115 is embedded in the first base groove 217. A second base groove 218 is formed between the boss 216 and the fourth base rib 215. The size of the second base groove 218 matches the size of the third base head rib 114.

Figure 14 and Figure 15As shown, the second base signal terminal 24 is provided with a third connecting groove 241 and a fourth connecting groove 242, which are respectively located on opposite sides of the first base groove 217. Furthermore, the second base signal terminal 24 is provided with a second base solder leg 243, which extends outside the base insulator 21. The structure of the third base signal terminal 25 in this embodiment is identical to that of the first base signal terminal 23. Specifically, the third base signal terminal 25 is provided with a second base connecting arm, a third base solder leg, a fifth connecting contact, and a sixth connecting contact, wherein the fifth connecting contact and the sixth connecting contact are respectively located on opposite sides of the second base groove 218. The second base connecting arm is provided with a fifth connecting protrusion and a sixth connecting protrusion. In this embodiment, the first base connecting arm 236 and the second base connecting arm are staggered and spaced apart along the length of the base insulator 21. The third base solder leg on the third base signal terminal 25 is located on the side of the base insulator 21 facing away from the base head. In this embodiment, the structure of the fourth base signal terminal 26 is identical to that of the second base signal terminal 24. Specifically, the fourth base signal terminal 26 is provided with a seventh connecting groove 261 and an eighth connecting groove 262, which are located on opposite sides of the second base groove 218. Furthermore, the fourth base signal terminal 26 is provided with a fourth base solder leg, which extends to the exterior of the base insulator 21.

[0061] like Figure 11 and Figure 16 As shown, the first base connecting arm 236 is provided with a first base engaging groove 2161 on the boss 216, and the first base connecting arm 236 on the second base signal terminal 24 is inserted into the first base engaging groove 2161 inside the base insulator 21 from the side of the base insulator 21 away from the base head, so that the first connecting protrusion 234 and the second connecting protrusion 235 on the first base connecting arm 236 are engaged in the first base engaging groove 2161 as shown in FIG. Figure 16 As shown, the first base signal terminal 23 is connected to the base insulator 21. The third base signal terminal 25 is connected to the base insulator 21 in the same manner as the first base signal terminal 23 is connected to the base insulator 21. Figure 11As shown, the boss 216 is provided with a second base engaging groove 2162 opposite the second base connecting arm. The second base connecting arm on the third base signal terminal 25 is inserted into the second base engaging groove 2162 inside the base insulator 21 from the side of the base insulator 21 facing away from the base head, so that the fifth and sixth connecting protrusions on the second base connecting arm engage with the second base engaging groove 2162, thereby connecting the third base signal terminal 25 to the base insulator 21. In this embodiment, the second base signal terminal 24 and the fourth base signal terminal 26 are embedded in the base insulator 21.

[0062] like Figure 17 As shown, when the base and the base head are connected, the first connecting contact 231 on the first base signal terminal 23 is snapped into the first connecting groove 131 of the first base head signal terminal 13, and the second connecting contact 232 on the first base signal terminal 23 is snapped into the second connecting groove 132 of the first base head signal terminal 13; the seventh connecting contact 161 of the fourth base head signal terminal 16 is snapped into the seventh connecting groove 261 of the fourth base signal terminal 26, and the eighth connecting contact 162 of the fourth base head signal terminal 16 is snapped into the eighth connecting groove 262 of the fourth base signal terminal 26. At the same time, when the base and the base head are connected, the fifth connecting contact on the third base signal terminal 25 is snapped into the fifth connecting groove of the third base head signal terminal 15, and the sixth connecting contact on the third base signal terminal 25 is snapped into the sixth connecting groove of the third base head signal terminal 15; the third connecting contact 141 of the second base head signal terminal 14 is snapped into the third connecting groove 241 of the second base signal terminal 24, and the fourth connecting contact 142 of the second base head signal terminal 14 is snapped into the fourth connecting groove 242 of the second base signal terminal 24.

[0063] During the connection between the base and the head, the first guide arc 1214 will contact the fourth guide arc 2213, the second guide arc 1221 will contact the boss 216, and the third guide arc 1222 will contact the fifth guide arc 2224. The above-mentioned guide arcs together guide the base and the head so that the head can be inserted into the base in the correct path. Figure 18 As shown, after the base and the base head are connected, the second base head fixing part 122 is located between the first contact elastic arm 2221 and the second contact elastic arm 2222 on the second base fixing part 222. During the process of inserting the base head into the base, the second base head fixing part 122 squeezes the first contact elastic arm 2221 and the second contact elastic arm 2222 to produce elastic deformation; when the base and the base head are connected, the first contact elastic arm 2221 and the second contact elastic arm 2222 are subjected to the elastic force to clamp the second base head fixing part 122, so that the base and the base head are stably connected.

[0064] In this embodiment, the base is provided with a plurality of first base signal terminals 23, a plurality of second base signal terminals 24, a plurality of third base signal terminals 25, and a plurality of fourth base signal terminals 26. The first base signal terminals 23 and the second base signal terminals 24 are arranged in a staggered manner along the length of the base insulator 21, and the third base signal terminals 25 and the fourth base signal terminals 26 are arranged in a staggered manner along the length of the base insulator 21. This maximizes the use of the base space, allows for the installation of as many signal terminals as possible, and enhances transmission effect and efficiency. Simultaneously, the base head is provided with a plurality of first base head signal terminals 13, a plurality of second base head signal terminals 14, a plurality of third base head signal terminals 15, and a plurality of fourth base head signal terminals 16. The first base head signal terminals 13 and the second base head signal terminals 14 are arranged in a staggered manner along the length of the base head insulator 11, and the third base head signal terminals 15 and the fourth base head signal terminals 16 are arranged in a staggered manner along the length of the base head insulator 11. This maximizes the use of the base head space, allows for the installation of as many signal terminals as possible, and enhances transmission effect and efficiency. After the signal terminal in the base is connected with the signal terminal in the base head, it can save resources while better meeting the transmission speed and quality required by 5G.

[0065] Example 3

[0066] See Figure 19 and Figure 20 The connector in Example 3 of the present invention is improved upon Example 2. Specifically, in Example 3, the second pedestal signal terminal 24 is further provided with a first bent section 244. This first bent section 244 extends to the exterior of the pedestal insulator 21 and then connects to the second pedestal solder leg 243. This arrangement increases the distance between the second pedestal solder leg 243 on the second pedestal signal terminal 24 and the first pedestal solder leg 237 on the first pedestal signal terminal 23, preventing the solder ball on the first pedestal solder leg 237 from connecting with the solder ball on the second pedestal solder leg 243 during soldering, which could cause a short circuit between the first pedestal signal terminal 23 and the second pedestal signal terminal 24. The structure of the fourth pedestal signal terminal 26 in this embodiment is identical to that of the second pedestal signal terminal 24.

[0067] The rest of the structure and working principle of Example 3 are the same as those of Example 2.

[0068] Example 4

[0069] See Figure 21 and Figure 22The connector in Example 4 of the present invention is improved upon Example 2. Specifically, the first base head signal terminal 13 in Example 2 is further provided with a second bent section 134. This second bent section 134 extends to the exterior of the base head insulator 11 and then connects to the first base head solder pin 133. This arrangement increases the distance between the first base head solder pin 133 on the first base head signal terminal 13 and the second base head solder pin 145 on the second base head signal terminal 14, preventing the solder ball on the first base head solder pin 133 from connecting with the solder ball on the second base head solder pin 145 during soldering, which could cause a short circuit between the first base head signal terminal 13 and the second base head signal terminal 14. The structure of the third base head signal terminal 15 in this embodiment is identical to that of the first base head signal terminal 13.

[0070] The rest of the structure and working principle of Example 4 are the same as those of Example 2.

[0071] Example 5

[0072] See Figure 23 The connector in Example 5 of the present invention is improved upon Example 4. Specifically, in Example 5, the second base head solder pin 145 on the second base head signal terminal 14 extends outside the base head insulator 11, and the fourth base head solder pin 163 on the fourth base head signal terminal 16 also extends outside the base head insulator 11. In this embodiment, the length of the first base head solder pin 133 on the first base head signal terminal 13 extending outside the base head insulator 11 is greater than the length of the second base head solder pin 145 on the second base head signal terminal 14 extending outside the base head insulator 11. The distance between the first base head solder pin 133 and the second base head solder pin 145 is greater than or equal to a first predetermined distance, which in this embodiment is 0.3 mm. This increased distance between the first base head solder pin 133 and the second base head solder pin 145 prevents solder balls on the first base head solder pin 133 from connecting with solder balls on the second base head solder pin 145 during soldering, thereby preventing a short circuit between the first base head signal terminal 13 and the second base head signal terminal 14. The length of the third solder pin on the third base head signal terminal 15 extending to the exterior of the base head insulator 11 is greater than the length of the fourth solder pin 163 on the fourth base head signal terminal 16 extending to the exterior of the base head insulator 11. The distance between the third solder pin and the fourth solder pin 163 is greater than or equal to a second predetermined distance, which in this embodiment is 0.3 mm. This increases the distance between the third and fourth solder pins 163, preventing the solder ball on the third solder pin from connecting with the solder ball on the fourth solder pin 163 during soldering, which could cause a short circuit between the third and fourth signal terminals 15 and 16.

[0073] The rest of the structure and working principle of Example 5 are the same as those of Example 4.

[0074] Example 6

[0075] See Figure 24 The connector in Example 6 of the present invention is improved upon Example 4. Specifically, in Example 6, the fourth base head weld leg 163 on the fourth base head signal terminal 16 also extends outside the base head insulator 11. In this embodiment, the length of the third base head weld leg on the third base head signal terminal 15 extending outside the base head insulator 11 is greater than the length of the fourth base head weld leg 163 on the fourth base head signal terminal 16 extending outside the base head insulator 11. The distance between the third base head weld leg 163 and the fourth base head weld leg 163 is greater than or equal to a third predetermined distance, which in this embodiment is 0.3 mm.

[0076] The rest of the structure and working principle of Example 6 are the same as those of Example 4.

[0077] Example 7

[0078] See Figure 25 The connector in Example 7 of the present invention is improved upon that in Example 5. Specifically, in Example 7, the length of the first solder pin 133 on the first base head signal terminal 13 extending to the exterior of the base head insulator 11 is shorter than the length of the second solder pin 145 on the second base head signal terminal 14 extending to the exterior of the base head insulator 11. Furthermore, the distance between the first solder pin 133 and the second solder pin 145 is greater than or equal to a fourth predetermined distance, which in this embodiment is 0.3 mm. This increases the distance between the first solder pin 133 and the second solder pin 145, preventing the solder ball on the first solder pin 133 from connecting with the solder ball on the second solder pin 145 during soldering, thereby preventing a short circuit between the first and second base head signal terminals 13 and 14. The length of the third solder pin on the third signal terminal 15 extending outside the base insulator 11 is greater than the length of the fourth solder pin 163 on the fourth signal terminal 16 extending outside the base insulator 11. The distance between the third and fourth solder pins 163 is greater than or equal to a fifth predetermined distance, which in this embodiment is 0.3 mm. This increases the distance between the third and fourth solder pins 163, preventing the solder ball on the third solder pin from connecting with the solder ball on the fourth solder pin 163 during soldering, which could cause a short circuit between the third and fourth signal terminals 15 and 16.

[0079] The rest of the structure and working principle of Example 7 are the same as those of Example 5.
