Description

Technical Field

[0001] This utility model relates to the field of high-frequency connectors, specifically a high-frequency connector terminal assembly structure. Background Technology

[0002] High-frequency connectors are electronic connectors specifically designed for transmitting high-frequency signals (typically frequencies above 3 MHz, reaching millimeter-wave bands such as 40 GHz or even higher). They are crucial in applications such as radio frequency (RF), microwave, and high-speed digital signal transmission, minimizing signal loss, reflection, and interference to ensure signal integrity.

[0003] In the existing technology, terminals and insulators are usually connected as a single unit. Although this has advantages in simplifying assembly and improving sealing, if any part of the terminal or insulator is damaged, the entire unit must be replaced, and it cannot be repaired separately. The existing high-frequency connector terminal assembly structure is not convenient for partially replacing damaged parts while ensuring simple assembly and excellent sealing performance by connecting the insulator and terminal separately. At the same time, the existing terminal assembly structure is not convenient for changing the appearance according to the application of the connector, which reduces the aesthetics of the high-frequency connector. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in connecting insulators and terminals separately, in order to ensure simple assembly and excellent sealing performance while partially replacing damaged parts, and inconvenience in changing the appearance according to the application of the connector, this utility model proposes a high-frequency connector terminal assembly structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-frequency connector terminal assembly structure of this utility model includes a first terminal group, a first insulating block is sleeved on the surface of the first terminal group, a second insulating block is slidably connected to one side of the first insulating block, a second terminal group is connected through the interior of the second insulating block, a metal shell is snapped onto both sides of the first insulating block, and an outer sleeve is sleeved on the surface of the metal shell. A guide block is provided on one side of the first insulating block, and the surface of the guide block is slidably connected to a groove opened on one side of the second insulating block. A protrusion is provided on the bottom of the first insulating block, and the bottom of the protrusion overlaps in a connecting groove opened on the surface of the second insulating block. A stepped overlapping block is provided at the edge of one side of the first insulating block, and the bottom of the overlapping block overlaps at the top edge of the second insulating block. The bottom of the outer sleeve is provided with a first one-way locking block, and a bottom fixing piece is engaged with the surface of the first one-way locking block. A second one-way locking block is provided at the edges of both sides of the outer sleeve, and a side fixing piece is engaged with the surface of the second one-way locking block.

[0006] Preferably, the surface of the metal shell is provided with through holes, and the number of through holes is six, with an elastic arc-shaped piece provided on one side of each through hole.

[0007] Preferably, the inner surface of the outer sleeve is provided with a first groove on the side near the elastic arc-shaped piece, and the inner surface of the side fixing piece is provided with a second groove on the side near the elastic arc-shaped piece.

[0008] Preferably, limiting plates are fixedly connected to both sides of the first insulating block, and a metal shell overlaps the top of the limiting plates.

[0009] Preferably, one end of the second terminal group is provided with a insert, the surface of the insert is overlapped with a first insulating block, and the surface of the second terminal group near the insert is provided with an arc-shaped contact.

[0010] Preferably, a third one-way locking block is provided on both sides of the metal shell, and a limiting piece is engaged with the surface of the third one-way locking block.

[0011] The advantages of this utility model are: 1. This utility model, through the structural design of the first insulating block and the second insulating block, allows the second insulating block to be attached to the lower part of the side of the second insulating block during the assembly of the high-frequency connector. Then, the second insulating block is slid from bottom to top, while the guide block slides in the groove to ensure that the second insulating block does not deviate from the installation position. The second insulating block is slid until the protrusion is inserted into the connecting groove and the lap block is placed on the second insulating block, thus completing the assembly of the insulating block and the terminal. This allows the high-frequency connector terminal assembly structure to connect the insulator and the terminal in a separate manner, ensuring simple assembly and excellent sealing performance while allowing partial replacement of damaged parts. 2. Through the structural design of the outer sleeve, after the insulator, terminals and metal shell are assembled, the metal shell is inserted into the outer sleeve from bottom to top, and then the bottom fixing piece is inserted from bottom to top. The bottom fixing piece deforms when it passes through the arc edge of the first one-way locking block, and finally makes the first one-way locking block completely locked into the locking hole. The right angle edge of the first one-way locking block can effectively prevent the bottom fixing piece from falling off. Similarly, the second one-way locking block can lock into and fix the side fixing piece, thereby completely assembling the high-frequency connector. By changing the appearance of the outer sleeve, bottom fixing piece and side fixing piece, the appearance can be changed according to the occasion of use of the connector, thus improving the aesthetics of the high-frequency connector.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1-5 As shown, a high-frequency connector terminal assembly structure includes a first terminal group 1, a first insulating block 2 sleeved on the surface of the first terminal group 1, a second insulating block 3 slidably connected to one side of the first insulating block 2, a second terminal group 4 through-connected inside the second insulating block 3, a metal shell 5 snapped onto both sides of the first insulating block 2, and an outer sleeve 6 sleeved on the surface of the metal shell 5. A guide block 21 is provided on one side of the first insulating block 2. The surface of the guide block 21 is slidably connected to a groove 31 opened on one side of the second insulating block 3. A protrusion 22 is provided at the bottom of the first insulating block 2. The bottom of the protrusion 22 overlaps in a connecting groove 32 opened on the surface of the second insulating block 3. A stepped overlapping block 23 is provided at the edge of one side of the first insulating block 2. The bottom of the overlapping block 23 overlaps at the top edge of the second insulating block 3. The bottom of the outer sleeve 6 is provided with a first one-way locking block 61, and the surface of the first one-way locking block 61 is engaged with a bottom fixing piece 7. The edges on both sides of the outer sleeve 6 are provided with a second one-way locking block 62, and the surface of the second one-way locking block 62 is engaged with a side fixing piece 8. During operation, thanks to the structural design of the first insulating block 2 and the second insulating block 3, when assembling the high-frequency connector, the second insulating block 3 is placed against the lower part of its side. Then, the second insulating block 3 is slid upwards, while the guide block 21 slides in the groove 31 to ensure the second insulating block 3 does not deviate from its installation position. The second insulating block 3 continues to slide until the protrusion 22 is inserted into the connecting groove 32 and the lap block 23 rests on the second insulating block 3, completing the assembly of the insulating block and the terminal. This allows the high-frequency connector terminal assembly structure to connect the insulator and the terminal in a separate manner, ensuring easy assembly and excellent sealing performance while allowing for partial replacement of damaged parts. The outer sleeve 6 further facilitates this process. In this structural design, after assembling the insulator, terminals, and metal shell 5, the metal shell 5 is inserted into the outer sleeve 6 from bottom to top, and then the bottom fixing piece 7 is inserted from bottom to top. The bottom fixing piece 7 deforms when passing through the arc-shaped edge of the first one-way locking block 61, and finally makes the first one-way locking block 61 completely locked into the locking hole. The right-angle edge of the first one-way locking block 61 can effectively prevent the bottom fixing piece 7 from detaching. Similarly, the second one-way locking block 62 can lock into and fix the side fixing piece 8, thereby completely assembling the high-frequency connector. By changing the appearance of the outer sleeve 6, the bottom fixing piece 7, and the side fixing piece 8, the appearance can be changed according to the occasion in which the connector is used, thus improving the aesthetics of the high-frequency connector.

[0017] Furthermore, the surface of the metal shell 5 is provided with through holes 51, and the number of through holes 51 is six. An elastic arc-shaped piece 52 is provided on one side of the through holes 51. During operation, the elastic arc-shaped piece 52 deforms elastically and clamps the plug when it is inserted, thus improving the stability of the plug insertion.

[0018] Furthermore, a first groove 63 is provided on the inner surface of the outer sleeve 6 near the elastic arc-shaped piece 52, and a second groove 81 is provided on the inner surface of the side fixing piece 8 near the elastic arc-shaped piece 52. During operation, the first groove 63 and the second groove 81 provide space for the deformation of the elastic arc-shaped piece 52 when the plug is inserted.

[0019] Furthermore, limiting plates 24 are fixedly connected to both sides of the first insulating block 2, and a metal shell 5 is overlapped on the top of the limiting plates 24; During operation, the position of the insulator and terminal within the metal shell 5 can be controlled by the limiting plate 24 during the assembly of the insulator and terminal with the metal shell 5.

[0020] Furthermore, one end of the second terminal group 4 is provided with a insert 41, the surface of the insert 41 is overlapped with the first insulating block 2, and the surface of the second terminal group 4 is provided with an arc-shaped contact 42 on the side near the insert 41. During operation, the insert 41 is inserted into the first insulating block 2 during the assembly of the second insulating block 3 and the first insulating block 2 to improve the overall structure. The arc-shaped contact 42 generates elastic deformation during insertion and removal, providing continuous pressure to ensure that the contact and interface fit tightly and reduce contact resistance.

[0021] Furthermore, a third one-way locking block 53 is provided on both sides of the metal shell 5, and a limiting piece 9 is engaged with the surface of the third one-way locking block 53; During operation, by setting the third one-way locking block 53 and the limiting piece 9, after the insulator and terminal are inserted into the metal shell 5 from bottom to top until the limiting plate 24 overlaps with the metal shell 5, the limiting piece 9 is locked in by the third one-way locking block 53, which can connect the insulator, terminal and metal shell 5 into a whole.

[0022] Working principle: When assembling the high-frequency connector, the second insulating block 3 is attached to the lower part of the side of the second insulating block 3. Then, the second insulating block 3 is slid from bottom to top. At the same time, the guide block 21 slides in the slide groove 31 to ensure that the second insulating block 3 does not deviate from the installation position. The second insulating block 3 is slid until the protrusion 22 is inserted into the connecting groove 32 and the overlapping block 23 is placed on the second insulating block 3, completing the assembly of the insulating block and the terminal. Then, the insulator and the terminal are inserted into the metal shell 5 from bottom to top until the limiting plate 24 overlaps with the metal shell 5. After the limiting piece 9 is inserted through the third one-way locking block 53, the insulator, the terminal and the metal shell 5 can be connected as a whole. Finally, the bottom fixing piece 7 is inserted into the first one-way locking block 61 and the side fixing piece 8 is inserted into the second one-way locking block 62, completing the overall assembly of the high-frequency connector.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
