[0027] The utility model will be described in detail below in combination with the embodiments shown in the drawings. However, the embodiments do not limit the utility model, and the changes in structure, method or function made by those skilled in the art based on the embodiments are all included in the protection scope of the utility model.
[0028] As Figures 1 to 8 shown, the utility model provides a novel multi-band board-to-board high-frequency connector 100, including along the length direction extends the insulating body 1, first group of conductive terminal 20 and second group of conductive terminal 30 are fixed in the insulating body 1 along the length direction arrangement respectively, first group of conductive terminal 20 and second group of conductive terminal 30 all include several conductive terminals 4;
[0029] The conductive terminal 4 includes:
[0030] The contact part 41 extends in the vertical direction, and the contact part 41 includes the first surface 411 and the second surface 412 arranged oppositely.
[0031] The glue sealing part 42 is protruded from the top of the contact part 41 and forms the first sharp head face 421, the second sharp head face 422 and the third sharp head face 423 connected in sequence, and the first sharp head face 421 and the third sharp head face 423 are arranged oppositely; the third sharp head face 423 is connected with the second surface 412, and the first sharp head face 421 is spaced from the first surface 411.
[0032] Therefore, in the utility model, the glue sealing part 42 is protruded from the top of the contact part 41, the third sharp head face 423 is connected with the second surface 412, and the first sharp head face 421 is spaced from the first surface 411, so that the first sharp head face 421 is not directly connected with the first surface 411, and the thickness of the glue sealing part 42 relative to the contact part 41 is overall thin, so that the plastic at the glue sealing part 42 is not too little during the glue sealing process, the combination of the plastic and the glue sealing part 42 is more compact, and the terminal is not easy to be lifted and separated.
[0033] As Figure 3 shown, the contact part 41 further comprises a connecting surface 413 at the top thereof, which is connected between the first surface 411 and the first pointed surface 421. The connecting surface 413 is a plane, and since the connecting surface 413 is connected between the first surface 411 and the first pointed surface 421, the first pointed surface 421 is spaced apart from the first surface 411. Of course, if other ways are adopted, for example, the connecting surface 413 is other connecting structures, as long as the first surface 411 and the first pointed surface 421 are spaced apart from each other and not connected, the purpose of the utility model can be achieved.
[0034] In this embodiment, an obtuse angle is formed between the connecting surface 413 and the first pointed surface 421 and the first surface 411. Thus, more plastic can be accommodated at the angle between the first pointed surface 421 and the connecting surface 413, so that the glue sealing part 42 can be more stably fixed in the insulating body 1. Of course, if the connecting surface 413 is perpendicular to the first pointed surface 421 and the first surface 411, the purpose of the utility model can also be achieved.
[0035] Furthermore, specifically, the first pointed surface 421 and the third pointed surface 423 are parallel, so that the glue sealing part 42 is overall thin and elongated. Of course, if the first pointed surface 421 and the third pointed surface 423 are not parallel and have a certain angle between their extension surfaces, as long as the glue sealing part 42 is overall thin, the purpose of the utility model can be achieved.
[0036] As Figure 3 shown, the third pointed surface 423 is in the same plane as the extension direction of the second surface 412. That is, the third pointed surface 423 extends from the second surface 412 and is in the same plane. As described above, the first pointed surface 421 and the third pointed surface 423 are parallel, so that the first pointed surface 421 is also parallel to the second surface 412. Furthermore, in this specific embodiment, the first surface 411 and the second surface 412 are also generally parallel, so that the first pointed surface 421 and the third pointed surface 423 are also parallel to the first surface 411.
[0037] As Figures 4 to 7 shown, the glue sealing part 42 further comprises a fourth pointed surface 424 and a fifth pointed surface 425 connected between the first pointed surface 421 and the third pointed surface 423, and the fourth pointed surface 424 and the fifth pointed surface 425 converge towards the top direction. The fourth pointed surface 424 and the fifth pointed surface 425 are connected between the first pointed surface 421 and the third pointed surface 423, and are both connected to the second pointed surface 422. Thus, the glue sealing part 42 is overall a trapezoid with uniform thickness, so as to be more closely combined with the plastic.
[0038] The insulating body 1 is internally concave from top to bottom to form a docking space 11, and the insulating body 1 is arranged with a plurality of terminal receiving grooves 12 along the edge of the docking space 11, and the conductive terminal 4 can be inlaid and accommodated in the terminal receiving groove 12; the first surface 411 of the contact part 41 is exposed outward from the docking space 11.
[0039] The insulating body 1 is in the shape of a cuboid as a whole, and is internally concave from the top surface to form a docking space 11 for connecting with a docking connector. The front side and the rear side of the docking space 11 of the insulating body 1 are arranged with a plurality of terminal receiving grooves 12, the first group of conductive terminals 20 are accommodated in the terminal receiving grooves 12 on the front side of the docking space 11, and the second group of conductive terminals 30 are accommodated in the terminal receiving grooves 12 on the rear side of the docking space 11. The conductive terminals 4 can be well adapted in the insulating body 1.
[0040] Of course, the first group of conductive terminals 20 and the second group of conductive terminals 30 are symmetrically arranged in the front-rear direction, and the first surface 411 of the contact part 41 is exposed toward the docking space 11. The first group of conductive terminals 20 and the second group of conductive terminals 30 are relatively symmetrical, so that the number of conductive terminals 4 in the first group of conductive terminals 20 and the second group of conductive terminals 30 is consistent and arranged in pairs, and the first surface 411 of the contact part 41 of the conductive terminal 4 is exposed to the docking space 11 to be connected with a docking connector.
[0041] The insulating body 1 further comprises an inlaid part 13 located at the opening of the docking space 11, and the inlaid part 13 is inlaid with the sealing part 42.
[0042] The inlaid part 13 is located at the opening of the terminal receiving groove 12 close to the docking space 11, and protrudes from the top of the terminal receiving groove 12 to the docking space 11. The inlaid part 13 is inlaid with the sealing part 42 to fix the top of the conductive terminal 4 on the insulating body 1, preventing the top of the conductive terminal 4 from being raised.
[0043] The insulating body 1 further comprises a main body part 14 located below the docking space 11, and the conductive terminal 4 is also mainly fixed in the main body part 14. Specifically, the conductive terminal 4 further comprises a holding part 43 and a solder leg 44 successively extending from the contact part 41, the holding part 43 is accommodated in the insulating body 1, the solder leg 44 is bent outwardly and extends from the holding part 43, and at least part of the solder leg 44 is exposed at the bottom of the insulating body 1.
[0044] Specifically, the holding portion 43 is accommodated in the main body portion 14, and the soldering leg 44 extends from the holding portion 43. The soldering leg 44 of the first conductive terminal 4 extends forwardly, and the soldering leg 44 of the second conductive terminal 4 extends rearwardly. The bending angle between the soldering leg 44 and the holding portion 43 is substantially 90°. In the embodiment, the soldering leg 44 is located below the insulating body 1 and exposed outwardly to be better connected with other electronic devices.
[0045] In summary, the sealing portion 42 is protruded from the top of the contact portion 41, the third pointed surface 423 is connected with the second surface 412, and the first pointed surface 421 is spaced from the first surface 411, so that the first pointed surface 421 is not directly connected with the first surface 411. The thickness of the sealing portion 42 relative to the contact portion 41 is relatively thin as a whole, so that the plastic at the sealing portion is not too little during the sealing process, and the combination of the plastic and the sealing portion 42 is more compact, which is not easy to cause the conductive terminal 4 to be raised and separated from the insulating body 1 made of plastic material. In addition, the insulating body 1 also has a fitting portion 13 matched with the sealing portion 42 to be fitted with the conductive terminal 4.
