Description

Technical Field

[0001] The present invention relates to a terminal of an RF connector, and more particularly to an RF terminal tape structure. Background Art

[0002] RF connectors are generally applied to radio frequency fields such as mobile phones, computers, tablets, gaming devices, digital applications, wireless access points, etc., and their application scope is very wide. An RF connector has a terminal for electrical connection, and the terminal usually includes a metal housing (for grounding) and a metal center pin. During the manufacturing process, the housing needs to be stamped into shape by a stamping process first, then the center pin is inserted into the center position of the housing, and finally the main body is formed by an injection molding process, so as to realize the integral molding of the entire RF terminal.

[0003] Chinese invention patent CN206134993U discloses an RF radio frequency connector tape, which includes a housing tape and a pin tape. The housing tape and the pin tape are fixed by a welding process, and the signal terminal is located at the center of the grounding terminal, and is generated in the form of a tape to improve production efficiency.

[0004] However, the housing tape and the pin tape are respectively manufactured and formed, and it is inevitable that there will be errors in their sizes. Therefore, the positions of some signal terminals may deviate during welding. In addition, even if the influence of the error is eliminated, in order to ensure the accuracy of the welding position, a high precision is required, so the process difficulty is high. Summary of the Invention

[0005] The technical solution of the present invention is directed to the above situation. In order to solve the above problems, an RF terminal tape structure is provided, which is characterized in that: the RF terminal tape structure includes: a plurality of tape frames, a plurality of housing elements and a plurality of center pin elements. The tape frame has a main tape board and a secondary tape board. The housing element has a first bent board and a housing board. One end of the first bent board is connected to the main tape board, and the other end is connected to the housing board. The center pin element has a second bent board and a center pin. One end of the second bent board is connected to the secondary tape board, and the other end is connected to the center pin.

[0006] Further, the main tape board has a plurality of positioning holes.

[0007] Further, the main tape board and the secondary tape board face each other, the housing element is located inside the tape frame, and the center pin element is located outside the tape frame.

[0008] Further, there are a plurality of tape frames, and the plurality of tape frames are arranged in two rows, and the two rows of tape frames face each other one by one.

[0009] Further, two connecting rods are provided between two mutually facing tape frames, and the center pin element is located between the two connecting rods.

[0010] Furthermore, the other end of the first bent plate is connected to the middle part of the outer shell plate.

[0011] Furthermore, the outer shell element further has two substrate plates, both of which are connected to the outer shell plate, and the first bent plate is located between the two substrate plates.

[0012] After adopting the above technical solution, the effects of the present invention are as follows:

[0013] 1. Since the outer shell element and the center pin element are arranged on the same material frame, they can be integrally manufactured and formed using a set of molds. The dimensional controllability of the outer shell element and the center pin element is more stable, the error range is smaller, and the structure is also simpler.

[0014] 2. Since the outer shell element is provided with a first bent plate and the center pin element is provided with a second bent plate, only by ensuring the unity of the bending positions can it be ensured that the outer shell element and the center pin element reach the predetermined positions, and the process difficulty is relatively low.

[0018] It should be specifically noted that in the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined; the meaning of "several" is at least one. In all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, they are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0019] The technical solution of the present invention will be further described below through embodiments:

[0020] The present invention provides an RF terminal tape structure, as Figure 1As shown in the figure, the RF terminal strip structure includes: a plurality of strip frames 1, a plurality of housing components 2, and a plurality of center pin components 3. The strip frame 1 has a main strip board 11 and a secondary strip board 12. The housing component 2 has a first bent board 21 and a housing board 22. One end of the first bent board 21 is connected to the main strip board 11, and the other end is connected to the housing board 22. The center pin component 3 has a second bent board 31 and a center pin 32. One end of the second bent board 31 is connected to the secondary strip board 12, and the other end is connected to the center pin 32.

[0021] Combined with Figure 2 and Figure 3 As shown, the above RF terminal strip structure can be fixed as a whole, and then through the stamping process, the housing board 22 forms a ring-shaped housing. Then, the first bent board 21 and the second bent board 31 are bent, so that the center pin 32 is inserted into the center position of the housing. Finally, an injection molding process is used to form a plastic body 4, so that the entire RF terminal is integrally manufactured and formed.

[0022] Among them, since the housing component 2 and the center pin component 3 are arranged on the same strip frame 1, a set of molds can be used for integral manufacturing and forming. The dimensional controllability of the housing component 2 and the center pin component 3 is more stable, the error range is smaller, and the structure is also simpler.

[0023] Among them, since the housing component 2 is provided with the first bent board 21 and the center pin component 3 is provided with the second bent board 31, only by ensuring that the bending positions are unified can it be ensured that the housing component 2 and the center pin component 3 reach the predetermined positions, and the process difficulty is relatively low.

[0024] Specifically, the main strip board 11 has a plurality of positioning holes 13. The setting of the positioning holes 13 can facilitate the alignment operation in the stamping and injection molding processes.

[0025] Specifically, the main strip board 11 and the secondary strip board 12 face each other. The housing component 2 is located inside the strip frame 1, and the center pin component 3 is located outside the strip frame 1. During the bending process, the first bent board 21 is bent by 90°, and the housing formed by the housing board 22 is in an upright state. The second bent board 31 is bent by 180°, and the center pin 32 is inserted into the center position of the housing.

[0026] More specifically, there are multiple strip frames 1, and the multiple strip frames 1 are arranged in two rows, and the two rows of strip frames 1 face each other one by one. The above RF terminal strip structure can achieve multi-cavity production, greatly improving the production capacity.

[0027] More specifically, two connecting rods 5 are arranged between two mutually facing strip frames 1, and the center pin component 3 is located between the two connecting rods 5. The setting of the connecting rods 5 can connect the two rows of strip frames 1 to form a whole, and can play a protective role for the center pin component 3 before bending.

[0028] Specifically, the other end of the first bending plate 21 is connected to the middle part of the outer shell plate 22. During stamping, semi-circular plates are formed at both ends of the outer shell plate 22, thus finally forming a cylindrical outer shell.

[0029] More specifically, the outer shell element 2 further has two substrate plates 23, both of the two substrate plates 23 are connected to the outer shell plate 22, and the first bending plate 21 is located between the two substrate plates 23. Before stamping, the two substrate plates 23 are parallel to the outer shell plate 22, and after stamping, the two substrate plates 23 are turned over by 90°. The arrangement of the substrate plates 23 can play a supporting role for the plastic main body 4 and improve the stability of the product.

[0030] The above-described embodiments are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention should be included within the scope of the patent application of the present invention.
