Description

Technical Field

[0001] This application relates to an integrated multi-channel coaxial connector. Background Technology

[0002] With the development of technology, many electrical connections between modules now require dual-channel RF coaxial cables. Compared to single-channel RF coaxial cables, dual-channel RF coaxial cables can transmit multiple signals and save space. However, currently, existing dual-channel RF coaxial cables, in order to ensure the stability of the two-channel signal transmission and guarantee the relevant shielding performance, generally consist of an upper shield and a lower shield that fit together to fix the insulating body, the shielding spacer located between the two coaxial cables, and the inner conductor connector connecting the two coaxial cables. This involves many parts, and the structure of the upper and lower shields is relatively complex, making manufacturing difficult and more expensive than producing two RF coaxial cables.

[0003] Therefore, it is necessary to design a new solution to address the aforementioned technical problems. Utility Model Content

[0004] The purpose of this application is to provide an integrated multi-channel coaxial connector that has a simple structure and is easy to assemble.

[0008] Each of the aforementioned coaxial cable connectors includes: an insulator, an internal terminal mounted inside the insulator, and an outer housing surrounding the insulator;

[0009] The outer shell includes a cylindrical portion that docks with a docking connector and a main body portion that at least partially covers one end of the cylindrical portion, the other end of the cylindrical portion being open.

[0015] Furthermore, the limiting portions of the at least two coaxial cable connectors arranged side by side are adjacent to each other and together form an adjacent limiting portion, and at least one of the locking portions is locked and fixed to the adjacent limiting portion.

[0016] Furthermore, the limiting part and the cylindrical part of the same coaxial cable connector are independent of each other.

[0017] Furthermore, the limiting portion and the outer wall surface of the cylindrical portion of the same coaxial cable connector are spaced apart in a radial direction perpendicular to the axial direction of the cylindrical portion.

[0018] Furthermore, the main body plate extends upward from its two ends along the left and right directions perpendicular to the axial direction of the cylindrical portion to form sidewall portions, and each sidewall portion has a locking portion formed thereon;

[0024] The edge of the main body extension is provided with a limiting part at the position of the locking part formed at the end of the side wall portion away from the fastening part in the front-back direction. The locking part is locked and fixed to the limiting part.

[0025] Furthermore, the main body extension extends away from the side wall in the front-back direction and forms a bent portion. The bent portion extends towards the side wall in the front-back direction and forms two locking portions. The two locking portions are respectively locked and fixed to the main body extensions of two coaxial cable connectors arranged side by side.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be understood that the terms “comprising” and “having” as used herein, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may include other steps or units that are not expressly listed or that are inherent to such process, method, product, or apparatus.

[0038] To ensure the accuracy of the description throughout this application, all references to directions should be made using the format of "direction". Figure 1 For reference, the X-axis direction corresponds to the left-right direction; the Z-axis direction is defined as the front-back direction, with the positive Z-axis being front; and the Y-axis direction is defined as the up-down direction, with the positive Y-axis being up. The Z-axis and X-axis directions are also the radial directions of the cylindrical portion 131 described below, and the Y-axis direction is also the axial direction of the cylindrical portion 131 described below.

[0039] Please refer to the reference. Figures 1 to 6 As shown, this application discloses an integrated multi-channel coaxial connector, including two coaxial cable connectors 1 arranged side by side and a locking member 2 that fixes the two coaxial cable connectors 1 together. Each coaxial cable connector 1 includes an insulator 11, an internal terminal 12 installed within the insulator 11, and an outer shell 13 surrounding the insulator 11. The outer shell 13 includes a cylindrical portion 131 that mates with a mating connector (not shown) and a main body portion 132 that at least partially covers one end of the cylindrical portion 131. The other end of the cylindrical portion 131 is open for mating with the mating connector.

[0040] The insulator 11 includes a base (unlabeled) and an insulating main body 111 integral with the base and housed within the cylindrical portion 131. The internal terminal 12 includes a fixing section (unlabeled) fixed to the insulator 11, a contact section (unlabeled) protruding from the cylindrical portion 131 for mating with a mating connector, and a mating section (unlabeled), the mating section being used for fixed connection with the cable 4.

[0041] Please refer to the reference. Figures 1 to 6As shown in this application, the main body 132 has multiple limiting portions 1321 formed at its edge in the radial direction perpendicular to the axial direction of the cylindrical portion 131. The locking member 2 has a main body plate 21 and multiple locking portions 22. The main body portions 132 of the two coaxial cable connectors 1 arranged side by side are attached to the main body plate 21. The multiple locking portions 22 are respectively locked and fixed with the corresponding limiting portions 1321 to achieve integral fixation of the two coaxial cable connectors 1 arranged side by side to the locking member 2. The locking member 2 fixes the two coaxial cable connectors 1 as one unit. When the coaxial cable connectors 1 are mated with the mating connector, the locking portions 22 do not interfere with the elastic deformation of the cylindrical portion 131.

[0042] Specifically, in a preferred embodiment, the limiting portion 1321 and the cylindrical portion 131 of the same coaxial cable connector 1 are independent of each other and do not contact each other. In a more preferred embodiment, the limiting portion 1321 and the outer wall surface of the cylindrical portion 131 of the same coaxial cable connector 1 are spaced apart in a radial direction perpendicular to the axial direction of the cylindrical portion 131. This can more effectively ensure that the locking portion 22 does not interfere with the elastic deformation of the cylindrical portion 131. It also avoids the design of the locking member 2 from affecting the mating stability of the coaxial cable connector 1 and the mating connector.

[0043] Please refer to the reference. Figures 1 to 4 As shown, two coaxial cable connectors 1 are arranged adjacent to each other. The limiting portions 1321 of the two coaxial cable connectors 1 arranged side by side are arranged adjacently and together form an adjacent limiting portion 1320. At least one of the locking portions 22 is locked and fixed to the adjacent limiting portion 1320. Specifically, in this embodiment, the locking member 2 is formed by stamping and bending a single piece of metal plate. The main body plate 21 extends upward from both ends of its left and right edges in a direction perpendicular to the axial direction of the cylindrical portion 131 to form sidewall portions 211, and the locking portion 22 is formed on each sidewall portion 211. The main body plate 21 extends upward from one end edge of its front and back edges in a direction perpendicular to the axial direction of the cylindrical portion 131 to form an end wall portion 212, and the locking portion 22 is formed on the end wall portion 212. The end wall portion 212 extends to both ends along the left-right direction and forms a fastening portion 213, which respectively conforms to and is fastened to the outer wall surface of the side wall portion 211. A locking portion 22 formed on the end wall portion 212 is correspondingly locked to the adjacent limiting portion 1320. Furthermore, each side wall portion 211 also extends to the end away from the fastening portion 213 along the front-rear direction and forms a locking portion 22.

[0044] Furthermore, the main body 132 also has a main body extension 133 extending further along one end in the front-rear direction. The projection of the cylindrical part 131 and the main body extension 133 do not overlap in the axial direction of the cylindrical part 131. The limiting part 1321 is formed by bending the two ends of the main body 132 directly below the cylindrical part 131 upwards in the left-right direction. The limiting part 1321 is formed by bending the edge of the main body extension 133 upwards at the position of the locking part 22 formed at the end of the side wall part 211 away from the fastening part 213 in the front-rear direction. Each locking part 22 is locked and fixed to the limiting part 1321.

[0045] Furthermore, in a preferred embodiment of this application, the end of the main body extension 133 away from the side wall 211 along the front-rear direction is further extended to form a bent portion 220. The bent portion 220 extends towards the side wall 211 along the front-rear direction to form two locking portions 22. The two locking portions 22 are respectively locked and fixed to the locking portions 22 formed on the adjacent main body extensions 133 of the two side-by-side coaxial cable connectors 1. In a preferred embodiment, the bent portion 220 and the locking portions 22 formed on the end wall 212 are correspondingly arranged in the front-rear direction (that is, they are basically located on the same straight line in the front-rear direction) to ensure more stable fixation with the coaxial cable connector 1.

[0046] In this embodiment of the application, one locking member 2 fixes two coaxial cable connectors 1. Of course, in other embodiments, the number of coaxial cable connectors 1 can be increased, such as three, four, five or even more.

[0047] The manufacturing method of the integrated multi-channel coaxial connector of this application is as follows:

[0048] Step 1: Provide a metal plate (locking member 2), and form a locking part 22 extending upward on the two side wall portions 211 by stamping and bending, form a locking part 22 extending upward on the end wall portion 212 by stamping and bending, and form a locking part 22 extending upward on the bent portion 220 by stamping and bending.

[0049] Step 2: Provide two coaxial cable connectors 1, which are fixed side by side by the mold and then assembled and attached to the main body plate 21 of the locking component 2 from top to bottom;

[0050] Step 3: Two upwardly extending sidewall portions 211 are formed by stamping and bending, so that the locking portions 22 located on the sidewall portions 211 are locked and fixed with the limiting portions 1321 formed on both sides of the main body portion 132 of the coaxial cable connector 1;

[0051] Step 4: The upwardly extending end wall portion 212 is formed by stamping and bending, so that the locking portion 22 located on the end wall portion 212 is locked and fixed with the adjacent limiting portion 1320.

[0052] Step 5: By stamping and bending to form an upwardly extending bent portion 220, the locking portion 22 located on the bent portion 220 is locked and fixed to the locking portion 22 formed on the adjacent main body extension portion 133 of the two side-by-side coaxial cable connectors 1, and finally the assembly of the entire integrated multi-channel coaxial connector is completed.

[0053] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
