[0050] The present invention provides a high frequency connector for electrically connecting an electronic card (not shown) to a circuit board (not shown). Figure 1 and Figure 2 The high-frequency connector 10 includes an insulating body 100 and a plurality of conductive terminals 200 accommodated in the insulating body 100. The plurality of conductive terminals 200 are divided into a first row of terminals and a second row of terminals and are arranged in the insulating body 100. The conductive terminals 200 of each row of terminals are arranged along the longitudinal direction of the insulating body 100. The insulating body 100 is provided with an insertion space 101.

The second row of terminals includes a second differential signal terminal pair and a second ground terminal located next to the second differential signal terminal pair. The two signal terminals are separated by grounding electrons to achieve a signal shielding effect.

[0052] In order to improve the signal transmission rate, in actual applications, the first row of terminals usually includes multiple first differential signal terminal pairs and multiple first grounding terminals, and the first differential signal terminal pairs and the first grounding terminals are arranged at intervals. The second row of terminals usually includes multiple second differential signal terminal pairs and multiple second grounding terminals, and correspondingly, the second differential signal terminal pairs and the second grounding terminals are also arranged at intervals.

[0053] The high-frequency connector 10 further includes a metal connecting piece 300 , a plurality of grounding springs 400 and a metal shell 500 . The metal connecting piece 300 is longitudinally fixed to the insulating body 100 , the plurality of grounding springs 400 are transversely fixed to the insulating body 100 , and the metal shell 500 is sleeved on the insulating body 100 .

[0054] like Figure 3 As shown, the insulating body 100 includes a bottom wall 102 and side walls 103 extending in parallel from opposite sides of the bottom wall 102. The bottom wall 101 has an upper surface and a lower surface. The upper surface is exposed in the plug-in space 101, and the lower surface is used for the conductive terminal 200 to be installed from back to front or from top to bottom in the insulating body 100.

[0055] The insulating body 100 is provided with a terminal slot 110 and a pre-slot 120 parallel to and connected to the terminal slot 110. Figure 4 The terminal groove 110 includes a first terminal groove 111 located on the bottom wall 102 and a second terminal groove 112 and a third terminal groove 113 located on the side wall 103. The pre-slot 120 includes a first pre-slot 121 located on the bottom wall 102 and a second pre-slot 122 located on the side wall 103. The second pre-slot 122 does not extend beyond the third terminal groove 113 at the front end of the side wall 103. A guide surface 1221 is provided at the front end of the second pre-slot 122.

[0056] Optionally, the guide surface 1221 is configured as an inclined surface directly connected to the third terminal groove 113. As a preferred solution, Figure 5 and Figure 6 As shown, the angle α formed by the inclined surface and the horizontal plane is greater than 45 degrees.

[0057] The bottom wall 102 is provided with a connection groove 130 for receiving the metal connection sheet 300 and a plurality of grounding grooves 140 for receiving the grounding spring sheet 400. The connection groove 130 is provided along the longitudinal direction of the bottom wall 102, and the plurality of grounding grooves 140 are provided along the transverse direction of the bottom wall 102. Each grounding groove 140 is respectively connected with a pre-slot 120 for receiving the first grounding terminal and a pre-slot 120 for receiving the second grounding terminal, and the grounding groove 140 penetrates to the lower surface of the bottom wall 102 but does not penetrate to the upper surface of the bottom wall 102.

[0058] like Figure 5As shown, the conductive terminal 200 includes a retaining portion 210, an elastic arm 220 obliquely extending from the upper end of the retaining portion 210, and a welding portion 230 extending from the lower end of the retaining portion 210. The elastic arm 220 is connected to a contact arm 240, and a protruding contact portion 241 is provided on the contact arm 240.

[0059] The retaining portion 210 includes a first side and a second side. The first side is provided with at least one clamping point 211 for interfering with the insulating body 100 .

[0060] In one embodiment, two clamping points 211 are provided, and a notch 212 is provided on the second side. The notch 212 is located between the two clamping points 211. The notch 212 can improve the high-frequency characteristic impedance of the conductive terminal 200 to meet the needs of high-frequency signal transmission.

[0061] The first side is further provided with a bent guide portion 213, and the guide portion 213 is located below the clamping point 211. As a preferred solution, the guide portion 213 is bent from the first side and extends horizontally.

[0062] The second side is provided with a guiding portion 214 , and the guiding portion 214 is located below the guide portion 214 .

[0063] For example, Figure 8 and Fig. 9 As shown, when the conductive terminal 200 is assembled into the insulating body 100 from the back to the front, the conductive terminal 200 is first inserted into the pre-slot 120. As the conductive terminal 200 goes deeper, when the contact portion 241 of the conductive terminal 200 contacts the guide surface 1221 at the front end of the second pre-slot 122, under the guidance of the guide surface 1221 and the continued action of the thrust, the contact portion 241 is inserted into the third terminal groove 113, thereby driving the conductive terminal 200 to transition from the pre-slot 120 to the terminal groove 110, wherein, in Before the contact portion 241 contacts the guide surface 1221, the card point 211 does not interfere with the insulating body 100. Furthermore, as a preferred solution, before the contact portion 241 is inserted into the third terminal groove 113 through the guide surface 1221, the card point 211 does not interfere with the insulating body 100. At the same time, the guide portion 213 on the retaining portion 210 also gives the conductive terminal 200 a lateral thrust, thereby pushing the conductive terminal 200 from the pre-slot 120 into the terminal groove 110, thereby improving assembly efficiency.

[0064] In one embodiment, if Fig.10 and Fig.11 As shown, the first pre-slot 121 is provided with a chamfered slope 1211 that matches the guide portion 213. After the conductive terminal 200 is fully inserted, the horizontal extension portion of the guide portion 213 is located in the first pre-slot 121, and the second pre-slot 122 is in an empty state.

[0065] like Fig.12 As shown, the retaining portion 210 is accommodated in the first terminal groove 111, the elastic arm 220 is accommodated in the second terminal groove 112, and the contact arm 240 is accommodated in the third terminal groove 113. The third terminal groove 113 is provided with recesses 1131 on both sides of the contact arm 240. Since the relative dielectric constant of air is smaller than the relative dielectric constant of the insulating body 100, and the relative dielectric constant is proportional to the capacitance, the capacitance between adjacent conductive terminals 200 is reduced by providing recesses 1131 on both sides of the contact arm 240. In addition, the characteristic impedance between the conductive terminals 200 increases as the capacitance decreases. Therefore, the provision of the recesses 1131 in this embodiment further improves the high-frequency characteristic impedance of the conductive terminal 200.

[0066] The clamping points 211 and the guide portions 213 of the first row of terminals are arranged opposite to the clamping points 211 and the guide portions 213 of the second row of terminals. The first terminal groove 111 includes a clamping groove 1111 for accommodating the clamping points 211 and a receiving groove 1112 for accommodating the guide portions 213 . The receiving groove 1112 extends through the lower surface of the bottom wall 102 .

[0067] The first terminal groove 111 further includes a guiding groove 1113 for accommodating the guiding portion 214, and the guiding groove 1113 penetrates the lower surface of the bottom wall 102. After the conductive terminal 200 is fully inserted, the guiding portion 214 is engaged in the guiding groove 1113, which can further guide the position of the conductive terminal 200 in the insulating body 100 to ensure that its welding portion 230 is located in the same plane, and at the same time, it can also prevent the conductive terminal 200 from being over-assembled.

[0068] Optionally, the width of the first terminal groove 111 gradually decreases from the lower surface of the bottom wall 102 to the upper surface of the bottom wall 102 , so that the conductive terminal 200 can be stably retained in the insulating body 100 .

[0069] After the conductive terminal 200 is assembled, the metal connecting piece 300 is inserted into the connecting groove 130 so that the metal connecting piece 300 is longitudinally fixed to the bottom wall 102. Fig.13 As shown, a barrier 131 is disposed in the connection groove 130 , and a notch 310 corresponding to the barrier 131 is disposed at the lower end of the metal connection sheet 300 along the direction in which the metal connection sheet 300 is inserted into the connection groove 130 .

[0070] After the metal connecting piece 300 is assembled, the multiple grounding springs 400 are respectively inserted into the grounding groove 140, so that the multiple grounding springs 400 are respectively fixed to the bottom wall 102 horizontally. After the grounding springs 400 are inserted, the guide portion 213 of the first grounding terminal and the guide portion 213 of the second grounding terminal are in contact with the grounding springs 400 to form a grounding loop; because the metal connecting piece 300 is fixed to the bottom wall 102 longitudinally, the grounding springs 400 are also in contact with the metal connecting piece 300, and the metal connecting piece 300 and the grounding springs 400 together form a grounding loop.

[0071] In one embodiment, if Fig.14 and Fig.15 As shown, the grounding spring 400 includes a main body 410 and a first spring foot 420 and a second spring foot 430 located on both sides of the main body 410 . There is a distance between the first spring foot 420 and the second spring foot 430 and the main body 410 .

[0072] The first spring foot 420 extends into the pre-slot 120 for accommodating the first grounding terminal, and contacts the horizontally extending portion of the guide portion 213 of the first grounding terminal. The second spring foot 430 extends into the pre-slot 120 for accommodating the second grounding terminal, and contacts the horizontally extending portion of the guide portion 213 of the second grounding terminal. When the first spring foot 420 and the second spring foot 430 contact the guide portion 213 of the first grounding terminal and the guide portion 213 of the second grounding terminal respectively, the distance between the main body 410 can provide them with deformation space, thereby facilitating assembly.

[0073] Along the direction of the grounding spring 400 being inserted into the grounding slot 140, the lower end of the main body 410 of the grounding spring 400 is provided with a bayonet 440 engaged with the metal connecting piece 300, the opening of the bayonet 440 faces downward, and clamping parts 441 are provided on both sides of the bayonet 440. After the grounding spring 400 is inserted into the grounding slot 140, the bayonet 440 at the lower end of the grounding spring 400 is engaged with the upper end of the metal connecting piece 300, and the clamping parts 441 clamp the metal connecting piece 300 on the left and right sides, so that the grounding spring 400 is engaged with the metal connecting piece 300.

[0074] Optionally, refer again to Fig.13 The upper end of the metal connecting piece 300 is provided with a second notch 320 for locating the position where the grounding spring 400 engages with the metal connecting piece 300.

[0075] like Fig.16As shown, by engaging multiple grounding springs 400 with the metal connecting sheet 300, the metal connecting sheet 300 can connect multiple first grounding terminals, multiple second grounding terminals and multiple grounding springs 400, thereby improving the grounding performance of the high-frequency connector 10. The metal connecting sheet 300 and the grounding springs 400 together also surround and isolate the differential signal terminal pairs to achieve the purpose of shielding and anti-interference.

[0076] In other embodiments, the bayonet 440 may also be provided at the upper end of the main body 410, and the connecting groove 130 for accommodating the metal connecting piece 300 may not be provided on the bottom wall 102. During assembly, the plurality of grounding spring pieces 400 are first inserted into the grounding grooves 140 respectively, and then the metal connecting piece 300 is inserted into the upper ends of the plurality of grounding spring pieces 400. The metal connecting piece 300 is then inserted into the bayonet 440 at the upper ends of the grounding spring pieces 400. The clamping portions 441 on both sides of the bayonet 440 clamp the metal connecting piece 300 left and right, thereby achieving the engagement between the metal connecting piece 300 and the plurality of grounding spring pieces 400. Similarly, the metal connecting piece 300 can connect the plurality of first grounding terminals, the plurality of second grounding terminals and the plurality of grounding spring pieces 400.

[0077] The insulating body 100 of the high-frequency connector 10 of the embodiment of the present invention is provided with a terminal slot 110 and a pre-slot 120 parallel to and connected with the terminal slot 110, the terminal slot 110 includes a first terminal slot 111 located on the bottom wall 102 and a second terminal slot 112 and a third terminal slot 113 located on the side wall 103, the pre-slot 120 includes a first pre-slot 121 located on the bottom wall 102 and a second pre-slot 122 located on the side wall 103, and the second pre-slot 122 extends at the front end of the side wall 103 without exceeding the first pre-slot 121. The third terminal slot 113 and the front end of the second pre-slot 122 are provided with a guide surface 1221. During assembly, the conductive terminal 200 is first inserted into the pre-slot 120. When the contact portion 241 of the conductive terminal 200 contacts the guide surface 1221 at the front end of the second pre-slot 122, the guide surface 1221 can guide the contact portion 241 of the conductive terminal 200 to be inserted into the third terminal slot 113, thereby driving the conductive terminal 200 to transition from the pre-slot 120 to the terminal slot 110, and preventing the conductive terminal 200 from deforming.

[0078] The present invention also provides a high frequency connector. Fig.17 , which is different from the above-mentioned embodiment in that the bottom wall of the insulating body 100B of the high-frequency connector 10B is not fixed with a metal connecting piece and a grounding spring piece; Fig.18 and Fig.19 As shown, the guide portion 213B of the conductive terminal 200B is bent from the second side of the retaining portion 210B and extends toward the pre-slot 120B.

[0079] like Fig. 20As shown, when the conductive terminal 200B is assembled into the insulating body 100B from the back to the front, the conductive terminal 200B is first inserted into the pre-slot 120B. As the conductive terminal 200B goes deeper, the guide portion 213B gives the conductive terminal 200B a lateral thrust, so that the conductive terminal 200B can be pushed from the pre-slot 120B into the terminal slot 110B. Before the contact portion of the conductive terminal 200B is inserted into the third terminal slot through the guide surface, the clamping point 211B does not interfere with the insulating body 100B.

[0080] like Fig.21 As shown, the first pre-slot 121B includes a supporting groove 1211B that accommodates the extended portion of the guide portion 213B. The supporting groove 1211B penetrates to the lower surface of the bottom wall of the insulating body 100B, and the depth of the supporting groove 1211B is deeper than that of the remaining adjacent first pre-slots to form a step difference. When the conductive terminal 200B is fixed in the insulating body 100B, the front end of the guide portion 213B abuts against the front end of the supporting groove 1211B to prevent the conductive terminal 200 from being over-inserted.

[0081] The present invention also provides a high frequency connector. Figure 22-Figure 24 , which is different from the above-mentioned embodiment, is that the guide portion 213C of the conductive terminal 200C of the high-frequency connector 10C protrudes from the surface of the retaining portion 210C toward the pre-slot 120C, and the guide portion 213C is configured in the shape of a spring sheet, which is torn from the surface of the retaining portion 210C along its length direction, and one end of the spring sheet close to the elastic arm 220C is fixed to the retaining portion 210C, and the other end of the spring sheet is an open end, which protrudes into the pre-slot 120C.

[0082] In another embodiment, the guide portion 213C is a convex hump, both ends of which are fixed to the retaining portion 210C, and the upper end surface thereof protrudes from the surface of the retaining portion 210C and is in an arch shape.

[0083] like Fig.25 As shown, when the conductive terminal 200C is assembled into the insulating body 100C from back to front, the conductive terminal 200C is first inserted into the pre-slot 120C. As the conductive terminal 200C goes deeper, the guide portion 213C contacts the pre-slot 120C, giving the conductive terminal 200C a lateral thrust, and transitioning the conductive terminal 200C from the pre-slot 120C to the terminal slot 110C, wherein the card point 211C does not interfere with the insulating body 100C before the contact portion of the conductive terminal 200C is inserted into the third terminal slot through the guide surface.

[0084] like Fig.26As shown, the first terminal groove includes a guiding groove 1113C for accommodating the guiding portion 214C, the guiding groove 1113C penetrates to the lower surface of the bottom wall, and the depth of the guiding groove 1113C is deeper than the other adjacent first terminal grooves to form a step difference. After the conductive terminal 200C is fully inserted, the guiding portion 214C is engaged in the guiding groove 1113C to correct the position of the conductive terminal 200C in the insulating body 100C, and at the same time, it can also prevent the conductive terminal 200C from being over-assembled.
