Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a USB Type-C female connector. Background Technology

[0002] With the development of USB technology, USB transmission speeds are getting higher and higher. For example, the USB Type-C interface is small in size, easy to plug in, and features high-speed transmission. However, the smaller structural space makes the circuits more compact, increasing electromagnetic interference, and the radiated EMI during high-speed signal transmission can propagate in the space and interfere with other circuits.

[0003] In the prior art, to avoid the above situation, EMI springs are set inside the connector to prevent EMI. However, the structure of the traditional EMI springs themselves and their connection structure with external components are not stable enough. When subjected to external impact, they may bend or break, thus affecting their function. Utility Model Content

[0004] The purpose of this utility model is to provide a USB Type-C female connector, in which an electromagnetic shielding shell is fitted onto an injection-molded shell through a ring body, and a pair of horizontal plates of the extension body are respectively positioned in a pair of grooves and clamp the injection-molded shell. It is easy and stable to install, and can effectively avoid radiated EMI. In addition, the vertical and horizontal plates of the extension body have a larger contact area, which can achieve a better shielding effect.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 5 As shown, a USB Type-C female connector includes an inner core 10, an electromagnetic shielding shell 20, and a housing 30. The inner core 10 includes a core body 11 and an injection-molded shell 12 for wrapping and connecting the core body 11. The upper and lower ends of the injection-molded shell 12 are respectively provided with plate-shaped grooves 1201. The electromagnetic shielding shell 20 is preferably made of EMI electromagnetic shielding material. It includes an annular body 21 and symmetrical extensions 22 arranged at the upper and lower ends on the same side of the annular body 21. The annular body 21 has an inner cavity 200, which is sleeved on the injection-molded shell 12. The extensions 22 have an L-shaped structure and include a vertical plate 221 arranged on the annular body 21 and extending towards the inner cavity 200, and a horizontal plate 222 arranged on the vertical plate 221. Both vertical plates 221 abut against the injection-molded shell 12, and both horizontal plates 222 are respectively embedded in a pair of grooves 1201. The housing 30 has a cavity 300 and is fixedly sleeved on the inner core 10 and the electromagnetic shielding shell 20.

[0030] In this invention, by providing an electromagnetic shielding shell 20 on the injection-molded shell 12, the radiated EMI generated by the high-speed signal transmission of the inner core 10 can be effectively prevented, thus avoiding the transmission of radiated EMI in space and interference with other circuits. Specifically, the electromagnetic shielding shell 20 is fitted onto the injection-molded shell 12 through the inner cavity 200 of its annular body 21 to ensure stability on one side. The horizontal plate 222 in its extension body 22 is embedded in the groove 1201 on the injection-molded shell 12. Since there are two horizontal plates 222 and two grooves 1201 respectively located at the upper and lower ends of the injection-molded shell 12, and the horizontal plate 222 is connected to the annular body 21 through the vertical plate 221, a pair of horizontal plates 222 can clamp the injection-molded shell 12 to ensure stability on the other side. The horizontal plate 222 embedded in the groove 1021 can be stabilized in the horizontal direction. The above-mentioned clamping and embedding effects can relatively stably install the electromagnetic shielding shell 20 on the inner core 10. At the same time, since the annular body 21 and the horizontal plate 222 can form a large coverage area, it can have a better shielding effect.

[0031] The specific installation method of this utility model is as follows: The core 11 includes an upper row terminal module 111 (including an upper fixing seat and upper row terminals installed in the upper fixing seat), a partition 113 and a lower row terminal module 112 (including a lower fixing seat and lower row terminals installed in the lower fixing seat) stacked from top to bottom. After the three are positioned, they are wrapped by injection molding shell 12 to stably connect the three. The electromagnetic shielding shell 20 is fitted onto the injection molding shell 12 and positioned in a relative position. Then the shell 30 is installed on the outside.

[0032] Preferably, the annular body 21 includes a waist-shaped ring 21a and an extension plate 21b. A pair of extensions 22 are formed on the same side of the waist-shaped ring 21a, and the extension plate 21b is formed on the upper end of the other side of the waist-shaped ring 21a. The extension plate 21b can achieve a larger area coverage of the annular body 21 and also helps to stabilize the annular body 21 when it is fitted onto the injection-molded shell 12.

[0033] The horizontal cross-section of the groove 1201 is rectangular, and similarly, the horizontal cross-section of the horizontal plate 222 is also rectangular. By increasing the coverage area, a larger contact area can achieve good installation stability.

[0034] Furthermore, a positioning block 210 is provided on the inner wall of the inner cavity 200, and a positioning groove 1202 is provided on the injection molded shell 12. When the annular body 21 is fitted onto the injection molded shell 12, the positioning block 210 is embedded in the positioning groove 1202. The snap-fit ​​action can further ensure the stability of the electromagnetic shielding shell 20 on the injection molded shell 12.

[0035] Combination Figure 6 and Figure 7As shown, the housing 30 includes an inner shell 31 and an outer shell 32. The inner shell 31 forms the cavity 300 described above for housing the inner core 10 and the electromagnetic shielding shell 20. The outer shell 32 is snapped onto the inner shell 31, and a sealing plate 32a is provided on one side for sealing the cavity 300. Sealing one side of the cavity 300 with the sealing plate 32a can better ensure the installation stability of the inner core 10, especially ensuring its positional stability during the insertion process of the inner core 10.

[0036] Specifically, the outer shell 32 is provided with a bottom cavity 320 with an opening at the bottom end, the inner shell 31 is provided with a locking block 311 on the opposite side walls, and the outer shell 32 is provided with a locking groove 321 on the opposite side walls. The inner shell 31 is embedded in the bottom cavity 320, and a pair of locking blocks 311 are embedded in a pair of locking grooves 321 respectively, which can ensure the vertical stability of the inner shell 31 after it is installed on the outer shell 32.

[0037] Furthermore, a limiting block 322 is provided on the top wall of the outer shell 32 within the bottom cavity 320, and a limiting groove 312 is provided on the top wall of the inner shell 31 on the side away from the cavity 300. The limiting block 322 is embedded in the limiting groove 312, which can ensure the stability of the inner shell 31 and the outer shell 32 in the horizontal direction.

[0038] In addition, an upper protrusion 3131 is provided on the top wall of the inner shell 31 on one side of the cavity 300, and a lower protrusion 3132 is provided on the bottom wall of the inner shell 31 on one side of the cavity 300. The upper end of the injection molded shell 12 and the upper end of the electromagnetic shielding shell 20 are respectively provided with a first groove 121 and a second groove 211. Similarly, the lower ends of the two are also provided with grooves. The upper protrusion 3131 and the lower protrusion 3132 are respectively embedded in the grooves, which can restrict the position of the inner core 10 and the electromagnetic shielding shell 20 in the cavity 300. Furthermore, through the synergistic effect of the sealing plate 32a, the inner core 10 and the electromagnetic shielding shell 20 can be stably positioned in the cavity 300.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
