Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing electrical connectors, and in particular to a high-speed data connector. Background Art

[0002] An HSD connector is a High-Speed Data connector, that is, a high-speed data connector. Based on the four-core principle, it has symmetric and impedance-controlled transmission of 100 ohms, and is widely used in handheld products such as mobile phones, digital cameras, MP3 players, and personal digital assistants (PDAs), as well as in the field of automotive manufacturing.

[0003] An HSD connector is one of the most important auxiliary connectors in automotive video, which is related to the integrity and efficiency of the video. A signal transmission component is provided inside the HSD connector, and is inserted and fixed in an insulating housing. The signal transmission component includes a signal wire, a terminal, an insulating column, and a metal shielding sleeve. Among them, the terminal is connected and conducted with the signal wire, and is internally fixed in the insulating column. The insulating column and the metal shielding sleeve are sequentially sleeved from the inside to the outside, and the whole is internally fixed in the insulating housing (as shown in Figure 1 ). In the prior art, the metal shielding sleeve is directly formed by turning, and a square convex portion is provided thereon to prevent itself from rotating relative to the insulating housing (as shown in Figure 2 ). However, processing the metal shielding sleeve by turning has the following disadvantages: the initial stock is a bar stock, and most of the material needs to be cut off during the turning process, resulting in extremely low material utilization rate, and the unit time cost of turning is relatively high, thus making the manufacturing cost of the metal shielding sleeve remain high. Therefore, it is urgent for technicians to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-speed data connector with a relatively low manufacturing cost and convenient for assembly.

[0005] To solve the above technical problem, the present invention relates to a high-speed data connector, which includes a signal transmission component and an insulating housing. A through-shaped first accommodation cavity is provided along the length direction of the insulating housing. The signal transmission component includes a signal wire, a terminal, an insulating column, a metal shielding sleeve, and a square insulating fixing member. The terminal is connected and conducted with the signal wire, and is internally fixed in the insulating column. The insulating column, the metal shielding sleeve, and the square insulating fixing member are sequentially sleeved from the inside to the outside, and the whole is internally fixed in the above first accommodation cavity. A through-shaped second accommodation cavity is provided along the length direction of the square insulating fixing member to facilitate the metal shielding sleeve to penetrate and be fixed along the left-to-right direction. The metal shielding sleeve is preferably a rolled rotating body.

[0006] As a further optimization of the technical solution disclosed in the present invention, a first abutting protrusion and a second abutting protrusion are provided on the metal shielding sleeve, which respectively abut against the left and right end faces of the square insulating fixing member to jointly limit the displacement of the square insulating fixing member in its length direction. The second accommodating cavity and the metal shielding sleeve are in a transition fit relationship, and a guiding inclined surface is provided on the second abutting protrusion. During the process of sleeving the metal shielding sleeve onto the square insulating fixing member, with the aid of the guiding inclined surface, the second abutting protrusion gradually squeezes into the second accommodating cavity, and during this process, the square insulating fixing member undergoes adaptive bulging to facilitate the passage of the second abutting protrusion.

[0007] As a further optimization of the technical solution disclosed in the present invention, the number of the second abutting protrusions is preferably set to 2 and is symmetrically distributed around the circumference of the metal shielding sleeve.

[0008] As a further optimization of the technical solution disclosed in the present invention, the second abutting protrusion is directly formed by stamping and profiling the side wall of the metal shielding sleeve.

[0009] As a further optimization of the technical solution disclosed in the present invention, an avoidance groove adapted to the outer shape of the second abutting protrusion is provided on the square insulating fixing member directly corresponding to the second abutting protrusion. The avoidance groove extends outward from the side wall of the second accommodating cavity. A first elastic arm extends further to the right from the right end face of the square insulating fixing member, and it also directly corresponds to the above-mentioned avoidance groove.

[0010] As a further optimization of the technical solution disclosed in the present invention, a second elastic arm also extends further to the right from the right end face of the square insulating fixing member and is offset relative to the first elastic arm. A third abutting protrusion is provided at the free end of the second elastic arm. Correspondingly, a limiting groove adapted to the third abutting protrusion is provided on the side wall of the first accommodating cavity.

[0011] As a further optimization of the technical solution disclosed in the present invention, a right-tilted guiding inclined surface is provided on the third abutting protrusion.

[0012] As a further optimization of the technical solution disclosed in the present invention, the first abutting protrusion is preferably in a sheet shape, and its number is set to 1, which is formed by punching and bending the side wall of the metal shielding sleeve.

[0013] As a further optimization of the technical solution disclosed in the present invention, a limiting notch is provided on the left side wall of the square insulating fixing member directly corresponding to the first abutting protrusion.

[0014] As a further optimization of the technical solution disclosed in the present invention, left-tilted guiding inclined surfaces are provided on both sides of the entrance of the above-mentioned limiting notch.

[0015] Compared with the high-speed data connector of the traditional design structure, in the technical solution disclosed in the present invention, the metal shielding sleeve abandons the long-term used turning part structure and adopts a rolled rotating body structure form, thus saving the usage amount of raw materials, improving the material utilization rate, and replacing the turning process with a high unit-time labor cost by stamping and rolling processes, thereby effectively reducing the manufacturing cost of the metal shielding sleeve. In addition, the presence of the square insulating fixing part preferably solves the subsequent difficult assembly problem caused by changing the design structure form of the metal shielding sleeve, and effectively ensures the reliability of the fixation between the metal shielding sleeve and the insulating housing.

Detailed implementation manners

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "left", "right", "up", "down", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] The following combines specific embodiments to further elaborate on the content of the present invention. Figure 3 The assembly schematic diagram of the high-speed data connector in the present invention is shown. It can be seen that it mainly consists of a signal transmission component 1 and an insulating housing 2. Among them, a through-shaped first accommodating cavity 21 is provided along the length direction of the insulating housing 2 (as shown in Figure 12 、 13 ). The signal transmission component 1 includes a signal wire 11, a wiring terminal (not shown in the figure), an insulating column 12, a metal shielding sleeve 13, and a square insulating fixing member 14. The wiring terminal is connected and conducted with the signal wire 11 and is internally placed and fixed in the insulating column 12. The insulating column 12, the metal shielding sleeve 13, and the square insulating fixing member 14 are sleeved in sequence from the inside to the outside and are integrally internally placed and fixed in the above-mentioned first accommodating cavity 21 (as shown in Figure 12 ). A through-shaped second accommodating cavity 141 is provided along the length direction of the square insulating fixing member 14 (as shown in Figure 9 、10 As shown in [the figure], it is convenient for the metal shielding sleeve 13 to be inserted and fixed along the left-to-right direction. The metal shielding sleeve 13 is preferably a rolled rotary body. In this way, the usage amount of raw materials is effectively saved, the material utilization rate is improved, and it is formed by stamping and rolling processes with relatively low labor-hour costs, thus effectively reducing the manufacturing cost of the metal shielding sleeve 13. In addition, the presence of the square insulating fixing member 14 preferably solves the subsequent difficult assembly problem caused by changing the design structure form of the metal shielding sleeve 13, and effectively ensures the reliability of the fixation between the metal shielding sleeve 13 and the insulating housing 2.

[0033] It is known that in the prior art, the metal shielding sleeve 13 and the square insulating fixing member 14 are generally assembled in an interference fit form. Although a good fixing effect can be achieved, the insertion operation is time-consuming and laborious, and the radial dimension errors of the metal shielding sleeve 13 and the square insulating fixing member 14 need to be strictly controlled during the manufacturing process, which inevitably increases the manufacturing cost. In view of this, a reference solution is disclosed in the present invention, specifically as follows: The metal shielding sleeve 13 is provided with a first abutting protrusion 131 and a second abutting protrusion 132, which respectively abut against the left and right end faces of the square insulating fixing member 14 to jointly limit the displacement of the square insulating fixing member 14 along its length direction (as Figure 11 shown in [the figure]). The second accommodation cavity 141 and the metal shielding sleeve 13 are in a transitional fit relationship, and a guiding inclined surface 1321 is provided on the second abutting protrusion 132 (as Figure 11 shown in [the figure]). During the insertion operation, the second abutting protrusion 132 first contacts the square insulating fixing member 14, and during the process of inserting the metal shielding sleeve 13 into the square insulating fixing member 14, with the help of the above guiding inclined surface 1321, the second abutting protrusion 132 gradually squeezes into the second accommodation cavity 141. During this process, the square insulating fixing member 14 undergoes adaptive bulging to facilitate the passage of the second abutting protrusion 132 until the left end of the square insulating fixing member 14 abuts against the first abutting protrusion 131.

[0034] It should be noted here that the first abutting protrusion 131 is preferably in a sheet shape (as Figure 7 , 8 shown in [the figure]), and its number is set to 1, which is blanked and bent by a mold before the metal shielding sleeve 13 is formed by rolling; in addition, before the metal shielding sleeve 13 is formed by rolling, the above second abutting protrusion 132 is directly stamped and profiled on the rolled sheet, and then finally formed by rolling.

[0035] Generally speaking, considering both the actual fixing effect and the manufacturing cost comprehensively, the number of the above second abutting protrusions 132 is preferably set to 2, and they can be symmetrically distributed around the circumference of the metal shielding sleeve 13 (asFigure 5 , 6 ).

[0036] As a further optimization of the above technical solution, a relief groove 142 matching the shape of the second stop protrusion 132 can be provided on the square insulating fixing member 14, just corresponding to the second stop protrusion 132. The relief groove 142 is formed by extending outward from the side wall of the second accommodating cavity 141. In addition, a first elastic arm 143 is further extended to the right from the right end face of the square insulating fixing member 14, and it also just corresponds to the above-mentioned relief groove 142 (such as Figure 9 , 10 ). When the metal shielding sleeve 13 is inserted, the second stop protrusion 132 is built into the avoidance groove 142 and slides freely along it. In the later stage of the insertion stage, the first elastic arm 143 is elastically deformed under the action of the pressing force of the second stop protrusion 132 to avoid, until the second stop protrusion 132 completely passes over the square insulating fixing piece 14, thereby achieving reliable fixation of the metal shielding sleeve 13 and the square insulating fixing piece 14. By adopting the above technical solution, the difficulty of assembling the metal shielding sleeve 13 can be further reduced.

[0037] Furthermore, a second elastic arm 144 may be further extended to the right from the right end face of the square insulating fixing member 14, and may be offset relative to the first elastic arm 143. A third stop protrusion 1441 (such as Figure 9 Correspondingly, a limiting groove 211 (as shown in FIG. 1 ) adapted to the third stop protrusion 1441 is provided on the side wall of the first accommodating cavity 21. Figure 12 , 13 As shown in ). In this way, under the premise of ensuring the reliability of the fixing of the square insulating fixing member 14 and the insulating housing 2, by adopting the above technical solution, the production and manufacturing costs are effectively reduced, and the assembly operation is convenient. Of course, as a further optimization of the above technical solution, a right-leaning guide inclined surface 14411 can also be provided on the third stop protrusion 1441 to facilitate its smooth sliding into the above-mentioned limiting groove 211.

[0038] In order to prevent the metal shielding sleeve 13 from rotating around its axial center line in the square insulating fixing member 14, a limited position notch 145 (such as Figure 9 , 10 When the metal shielding sleeve 13 is completely inserted into the square insulating fixing member 14, the first stop protrusion 131 is placed in the above-mentioned limiting notch 145 (as shown in Figure 7 , 8As shown in []. Of course, as a further optimization of the above technical solution, left-leaning guiding inclined surfaces 1451 may be provided on both sides of the entrance of the above-mentioned limiting notch 145 (as shown in Figure 9 []), so that the first gear-leaning protrusion 131 can smoothly enter the limiting notch 145.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
