Description

Technical Field

[0001] The present invention relates to an ultra-high frequency ultra-fine coaxial RF connector assembly, and more specifically, to an ultra-high frequency ultra-fine coaxial RF connector assembly that omits the central terminal of the RF board end to transmit ultra-high frequency millimeter wave band RF signals. Background Technology

[0002] In recent years, the micro coaxial RF connector assembly transmits RF signals through the micro coaxial RF line end connector and the micro coaxial RF board end connector in sequence. Due to its light, thin and short size and the ability to transmit RF signals in the micron-wave frequency band below 10GHz, it has been widely used in computers and their peripherals, communication products and consumer electronic products to transmit RF signals in the micron-wave frequency band.

[0003] The structural design of the known ultra-fine coaxial RF connector assembly is as follows Figures 1 to 6 As shown, the main purpose is to plug the ultra-fine coaxial RF line-end connector 5 into the ultra-fine coaxial RF board-end connector 3 to transmit RF signals. The main body 311 of the board-end center terminal 31 of the ultra-fine coaxial RF board-end connector 3 is set at the center position of its board-end shielding terminal 32, and the board-end center terminal 31 extends through the notch 321 reserved by its board-end shielding terminal 32 through the bottom extension body 312 to electrically contact the circuit substrate 4 at a position outside the board-end shielding terminal 32. The notch 321 can separate the board-end center terminal 31 and the board-end shielding terminal 32 to avoid the board-end center terminal 31 electrically contacting the board-end shielding terminal 32 to cause a short circuit. However, the notch of the board-end shielding terminal 32 321 will cause wave leakage, resulting in poor electrical shielding effect of the board-end shielding terminal 32, which is easy to cause electromagnetic coupling interference in the board-end shielding terminal 32, so that the ultra-fine coaxial RF line-end connector 5 of the known ultra-fine coaxial RF board-end connector assembly and the ultra-fine coaxial RF board-end connector 3 can only transmit RF signals in the millimeter wave band below 10GHz. Although this can meet the transmission requirements of RF signals in the 3G and 4G communication generations, the transmission capacity still cannot reach the transmission of RF signals in the ultra-high frequency millimeter wave band above 30GHz, and cannot meet the transmission requirements of the 5G communication generation for ultra-high frequency RF signals. This is an application bottleneck that needs to be overcome urgently in the current 5G communication generation.

[0004] Therefore, how to improve the above-mentioned defects and enhance the electrical shielding effect of the shielding terminal of the ultra-fine coaxial RF board-end connector so that the ultra-fine coaxial RF connector assembly can be used for the transmission of RF signals in the ultra-high frequency millimeter wave band is indeed a problem that people in the relevant technical field need to solve urgently. Therefore, the present invention improves the component structure of the ultra-fine coaxial RF connector assembly to solve the various problems that the current ultra-fine coaxial RF connector assembly cannot transmit RF signals in the ultra-high frequency millimeter wave band. Summary of the invention

[0005] In view of the above-mentioned disadvantages of the prior art, the present invention provides an ultra-high frequency extremely thin coaxial RF connector assembly, which is paired with a circuit board to transmit RF signals. The circuit board includes a substrate center terminal contact portion. The ultra-high frequency extremely thin coaxial RF connector assembly includes: an ultra-high frequency extremely thin coaxial RF board-end connector and an ultra-high frequency extremely thin coaxial RF wire-end connector. The ultra-high frequency extremely thin coaxial RF board-end connector includes a board-end shielding terminal, and the board-end shielding terminal has a board-end shielding terminal insertion ring. The ultra-high frequency extremely thin coaxial RF wire-end connector has a wire-end insulator, a wire-end elastic arm center terminal, and a wire-end shielding terminal. Among them, the wire-end elastic arm center terminal has a wire-end elastic arm center terminal body and a wire-end elastic arm center terminal contact portion. The wire-end elastic arm center terminal body is inserted through the wire-end insulator; the wire-end shielding terminal includes a wire-end shielding terminal insertion ring; the wire-end elastic arm center terminal contact portion is exposed on one side of the wire-end insulator and the wire-end shielding terminal insertion ring; the wire-end shielding terminal insertion ring is inserted into the board-end shielding terminal insertion ring from top to bottom, so that the wire-end elastic arm center terminal contact portion passes through the inside of the board-end shielding terminal insertion ring to directly electrically contact the substrate center terminal contact portion; and the wire-end elastic arm center terminal body has an elastic structure, and by elastically abutting against the substrate center terminal contact portion, the wire-end elastic arm center terminal contact portion is kept applying an abutting force to the substrate center terminal contact portion to ensure electrical contact between the wire-end elastic arm center terminal contact portion and the substrate center terminal contact portion.

[0006] Compared with the prior art, the ultra-high frequency extremely thin coaxial RF connector assembly of the present invention omits the setting of the RF board-end center terminal, so that the ultra-high frequency extremely thin coaxial RF wire-end connector can directly transmit RF signals to the circuit board without relying on the RF board-end center terminal, and the board-end shielding terminal does not need to reserve a notch for the board-end center terminal to pass through. Therefore, the board-end shielding terminal in the RF board-end connector of the present invention can effectively provide electrical shielding to avoid electromagnetic coupling interference in the board-end shielding terminal when the ultra-high frequency extremely thin coaxial RF connector assembly of the present invention transmits high-frequency RF signals, so that the ultra-high frequency extremely thin coaxial RF connector assembly of the present invention can transmit RF signals in the ultra-high frequency millimeter wave band. In addition, the wire-end elastic arm center terminal can directly electrically contact the circuit board while maintaining a stable contact force to ensure that the RF signal transmitted by the wire-end elastic arm center terminal can reach the circuit board smoothly.

[0047] The following content will be presented in conjunction with diagrams to illustrate the technical content of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. In particular, the proportional relationships and relative positions of the various components in the diagrams are for illustrative purposes only and do not represent the actual situation of the implementation of the present invention.

[0048] To make the disclosure more concise and clear, the same symbols will be used to describe components with the same or similar functions below, and the descriptions of the same or equivalent features will be omitted.

[0049] The present invention improves the structure of an ultra-thin coaxial RF connector assembly by omitting the RF board-end center terminal of the ultra-thin coaxial RF board-end connector, enabling the center terminal of the line-end elastic arm of the ultra-thin coaxial RF line-end connector to directly electrically contact the circuit board without relying on the RF board-end center terminal. In this way, the ultra-thin coaxial RF line-end connector can directly transmit RF signals to the circuit board. Thus, there is no need to set an RF board-end center terminal in the ultra-thin coaxial RF board-end connector. Therefore, the board-end shielding terminal in the ultra-high frequency ultra-thin coaxial RF board-end connector of the present invention can effectively provide electrical shielding, enabling the ultra-high frequency ultra-thin coaxial RF connector assembly of the present invention to provide RF signals in the ultra-high frequency millimeter wave band above 30 GHz.

[0050] First Embodiment:

[0051] Please refer to Figures 7 to 16 and Figures 23 to 38 , where, as shown in the respective diagrams referred to in the left column, the ultra-high frequency ultra-thin coaxial RF connector assembly 1 of the first embodiment is at least composed of an ultra-high frequency ultra-thin coaxial RF line-end connector 11 and an ultra-high frequency ultra-thin coaxial RF board-end connector 12, and is used to respectively cooperate with an RF coaxial cable 6 and a circuit board 2 to transmit RF signals in the ultra-high frequency millimeter wave band above 30 GHz. Among them, the circuit board 2 includes a substrate center terminal contact portion 21 and a substrate shielding loop 22, and the substrate shielding loop 22 surrounds the substrate center terminal contact portion 21 to provide electrical shielding for the substrate center terminal contact portion 21. The ultra-high frequency ultra-thin coaxial RF line-end connector 11 cooperates with the RF coaxial cable 6, and the RF coaxial cable 6 includes a cable center conductor 61 and a cable shielding conductor 62. The ultra-high frequency ultra-thin coaxial RF board-end connector 12 includes a board-end shielding terminal 121, and the board-end shielding terminal 121 has a board-end shielding terminal insertion ring 1211.

[0052] In the first embodiment, the ultra-high frequency extremely thin coaxial RF wire end connector 11 has a wire end insulator 111, a wire end elastic arm center terminal 112 and a wire end shield terminal 113. The wire end elastic arm center terminal 112 can be joined to the cable center conductor 61 of the RF coaxial cable 6, and has a wire end elastic arm center terminal body 1121 and a wire end elastic arm center terminal contact portion 1122. The wire end shield terminal 113 can be joined to the cable shield conductor 62 of the RF coaxial cable 6. The wire end insulator 111 has a wire end insulator body 1111, a wire end insulator upper cover 1112 and a wire end insulator accommodation space 1113, and the wire end insulator accommodation space 1113 is provided in the wire end insulator body 1111. The wire end insulator upper cover 1112 can be flipped upward relative to the wire end insulator body 1111 as shown in Figure 14 or Figure 32 shown, or moved upward relative to the wire end insulator body 1111 as shown in Figure 38 shown, to expose the wire end insulator accommodation space 1113 for placing the wire end elastic arm center terminal body 1121 into the wire end insulator accommodation space 1113. The wire end insulator upper cover 1112 can also be flipped downward relative to the wire end insulator body 1111 as shown in Figure 13 or Figure 31 shown, or moved downward relative to the wire end insulator body 1111 as shown in Figure 37 shown, to shield the wire end insulator accommodation space 1113 to confine the wire end elastic arm center terminal body 1121 in the wire end insulator accommodation space 1113, so that the wire end insulator 111 and the wire end elastic arm center terminal 112 form a semi-finished product SP of the RF wire end connector. In addition, as shown in Figure 31 and Figure 37 shown, the wire end insulator upper cover 1112 has a wire end insulator upper cover buckling structure 11121 for buckling the wire end insulator body 1111 to complete the positioning of the wire end insulator upper cover 1112.

[0053] The wire end elastic arm center terminal body 1121 is a cantilever terminal passing through the wire end insulator 111. The tail of the cantilever terminal has a wire end elastic arm center terminal joint portion 11211. The wire end elastic arm center terminal joint portion 11211 can be joined to the cable center conductor 61 of the RF coaxial cable 6 by means of soldering (as shown in Figure 23 ), riveting (as shown in Figures 24 to 24-1 ), crimping (as shown in Figure 25 ), or IDC (as shown in Figures 26 to 26-1 ) etc., so as to receive the RF signal from the cable center conductor 61.

[0054] As shown in Figures 27 to 30 and Figures 33 to 36As shown, the wire-end shielding terminal 113 includes a wire-end shielding terminal insertion ring 1131, a wire-end shielding terminal accommodation space 1132, a wire-end shielding terminal joint portion 1133, a wire-end shielding terminal cover 1134, and a wire-end shielding terminal body 1135. The wire-end shielding terminal accommodation space 1132 is used to accommodate the semi-finished product SP of the ultra-high frequency ultra-thin coaxial RF wire-end connector. The wire-end shielding terminal cover 1134 is joined to the wire-end shielding terminal body 1135 by, for example, snap-fastening, so as to confine the semi-finished product SP of the ultra-high frequency ultra-thin coaxial RF wire-end connector in the wire-end shielding terminal accommodation space 1132. Optionally, the wire-end shielding terminal insertion ring 1131 is arranged on the wire-end shielding terminal body 1135 as shown in Figure 30 or is arranged on the wire-end shielding terminal cover 1134 as shown in Figure 36 . Optionally, the wire-end shielding terminal cover 1134 and the root shielding terminal body 1135 can be formed as one body as shown in Figure 30 , so as to abut against the semi-finished product SP of the ultra-high frequency ultra-thin coaxial RF wire-end connector by bending, so as to confine the semi-finished product SP of the ultra-high frequency ultra-thin coaxial RF wire-end connector in the wire-end shielding terminal accommodation space 1132.

[0055] The wire-end shielding terminal joint portion 1133 joins the cable shielding conductor 62 of the RF coaxial cable 6. The center terminal contact portion 1122 of the wire-end elastic arm is exposed on one side of the wire-end insulator 111 and the wire-end shielding terminal insertion ring 1131. When the wire-end shielding terminal insertion ring 1131 is inserted into the board-end shielding terminal insertion ring 1211 from top to bottom, since the ultra-high frequency ultra-thin coaxial RF board-end connector 12 does not have a board-end center terminal, the center terminal contact portion 1122 of the wire-end elastic arm can pass through the inside of the board-end shielding terminal insertion ring 1211 to directly electrically contact the substrate center terminal contact portion 21, so as to ensure that the RF signal transmitted by the center terminal body 1121 of the wire-end elastic arm can reach the circuit board 2 smoothly. Moreover, the board-end shielding terminal 121 of the ultra-high frequency ultra-thin coaxial RF board-end connector 12 does not need to reserve a through-hole notch for the board-end center terminal like the known ultra-thin coaxial RF board-end connector shielding terminal. In the present invention, the center terminal contact portion 1122 of the wire-end elastic arm passes through the inside of the board-end shielding terminal insertion ring 1211 to directly electrically contact the substrate center terminal contact portion 21. In this way, the electrical shielding effect of the board-end shielding terminal 121 can be improved, and the ultra-high frequency ultra-thin coaxial RF connector assembly 1 of the present invention can be used to transmit RF signals in the ultra-high frequency millimeter wave band above 30 GHz.

[0056] In the first embodiment, the board-end shielding terminal 121 is electrically contacted with the substrate shielding circuit 22, so that the wire-end shielding terminal 113, the board-end shielding terminal 121, and the substrate shielding circuit 22 are electrically connected to form a shielding environment, so as to provide electrical shielding for the center terminal contact portion 1122 of the wire-end elastic arm and the substrate center terminal contact portion 21.

[0057] The board - end shielding terminal insertion ring 1211 and the wire - end shielding terminal insertion ring 1131 are both circular rings, enabling the board - end shielding terminal insertion ring 1211 and the wire - end shielding terminal insertion ring 1131 to rotate relative to each other to adjust the relative angle between the ultra - high - frequency ultra - fine coaxial RF wire - end connector 11 and the ultra - high - frequency ultra - fine coaxial RF board - end connector 12 in the ultra - high - frequency ultra - fine coaxial RF connector assembly 1, so as to adapt to the circuit board 2 to be matched.

[0058] In addition, regarding the inner - diameter size of the insertion ring, the wire - end shielding terminal insertion ring 1131 is larger than the board - end shielding terminal insertion ring 1211. Since the volume of the RF board - end connector 12 is too small, if the wire - end shielding terminal insertion ring 1131 is larger than the board - end shielding terminal insertion ring 1211, during the buckling process of the ultra - high - frequency ultra - fine coaxial RF wire - end connector 11 and the ultra - high - frequency ultra - fine coaxial RF board - end connector, the wire - end shielding terminal insertion ring 1131 will block the board - end shielding terminal insertion ring 1211, resulting in a blind - plug buckling situation where the position of the board - end shielding terminal insertion ring 1211 cannot be visually confirmed. Thus, when the wire - end shielding terminal insertion ring 1131 is inserted into the board - end shielding terminal insertion ring 1211 from top to bottom, the wire - end shielding terminal insertion ring 1131 may squeeze the board - end shielding terminal insertion ring 1211 without being aligned as expected, causing damage. In response to this, in the first embodiment, a guiding column 1114 is added to the insertion end of the wire - end insulator 111. The guiding column 1114 extends outwards from the inside of the wire - end shielding terminal insertion ring 1131 to form a guiding structure. During the process of the wire - end shielding terminal insertion ring 1131 inserting into the board - end shielding terminal insertion ring 1211, the wire - end shielding terminal insertion ring 1131 is guided to align with the board - end shielding terminal insertion ring 1211, so that the wire - end shielding terminal insertion ring 1131 can be smoothly inserted into the inside of the board - end shielding terminal insertion ring 1211 under blind - plug conditions, enabling the wire - end elastic - arm center - terminal contact portion 1122 to approach the substrate center - terminal contact portion 21, ensuring that the wire - end elastic - arm center - terminal contact portion 1122 can be electrically contacted with the substrate center - terminal contact portion 21.

[0059] Furthermore, in the first embodiment, when the wire - end insulator upper cover 1112 of the wire - end insulator is flipped downwards or moved downwards to shield the wire - end insulator accommodation space 1113, the wire - end insulator upper cover 1112 of the wire - end insulator 111 can push against the wire - end elastic - arm center - terminal body 1121, causing the wire - end elastic - arm center - terminal body 1121 to form an elastic structure such as an elastic cantilever. By means of the elastic cantilever, elastic abutment is provided to the substrate center - terminal contact portion 21 to maintain a stable abutting force exerted by the wire - end elastic - arm center - terminal contact portion 1122 on the substrate center - terminal contact portion 21, so as to achieve stable electrical contact between the wire - end elastic - arm center - terminal contact portion 1122 and the substrate center - terminal contact portion 21.

[0060] Second Embodiment:

[0061] Please refer to Figures 17 to 22 simultaneously. As shown in the diagrams referred to in the left column, the biggest difference between the second embodiment and the first embodiment lies in that, regarding the inner diameter size of the plugging ring, the plugging ring 1131 of the wire-end shielding terminal is smaller than the plugging ring 1211 of the board-end shielding terminal. Thus, during the process of the plugging ring 1131 of the wire-end shielding terminal plugging into the plugging ring 1211 of the board-end shielding terminal, the plugging ring 1211 of the board-end shielding terminal is in a visible state for the plugging ring 1211 of the wire-end shielding terminal to align, so that the plugging ring 1131 of the wire-end shielding terminal can be inserted into the interior of the plugging ring 1211 of the board-end shielding terminal without blind plugging, and to avoid the plugging ring 1131 of the wire-end shielding terminal squeezing the plugging ring 1211 of the board-end shielding terminal during the top-down plugging process without expected misalignment, thereby causing damage, enabling the central terminal contact portion 1122 of the wire-end elastic arm to approach the central terminal contact portion 21 of the substrate, and thus ensuring that the central terminal contact portion 1122 of the wire-end elastic arm can be in electrical contact with the central terminal contact portion 21 of the substrate.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limitations on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
