Description

Technical Field

[0001] This invention relates to the field of electronic devices, and more particularly to an electrical connector. Background Technology

[0002] Type-C female electrical connectors are widely used in various electronic products, such as power banks, Bluetooth headsets, and mobile phones, for charging or signal transmission. Existing connectors have a relatively complex structure with many components, especially due to the numerous terminals used for transmitting electrical energy or signals. Type-C female connectors also feature two independent locking mechanisms. Existing Type-C female connectors are prone to static electricity buildup; if this static electricity is not discharged, it can easily cause noise during signal transmission.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] like Figure 1-5As shown, the Type-C female electrical connector of this embodiment includes a metal housing 1000, an insulating body 2000, several terminals, a locking latch 23, and a locking latch 24. The Type-C female electrical connector also has a connecting portion. The locking latches 23 and 24 are connected to the metal housing 1000 through their connecting portions. In this embodiment, the connecting portions of the locking latches 23 and 24 are integrated into a single unit, namely the connecting portion 25. In this embodiment, the Type-C female electrical connector includes two layers of terminals. The connecting portion 25 is connected to the tail of the locking latches 23 and 24. The locking latch 23 has a channel 231 through which the mating portion 212 of the terminal 21 passes. The locking latch 24 has a channel 241 through which the mating portion 222 of the terminal 22 passes. Both the locking latches 23 and 24 are electrically connected to the metal housing 1000 through the connecting portion 25, thereby releasing static electricity within the connector and preventing noise caused by static electricity. The metal housing 1000 is welded to the connecting portion 25, thereby fixing the metal housing 1000 to the insulating body 2000 and facilitating the release of static electricity within the connector. Specifically, the connecting portion 25 has an L-shaped lug 259, which is welded to the metal housing 1000 via its upper wall 2591. The connecting portion 259 is partially embedded within the insulating body 2000. The connecting portion 25 protrudes from the protrusion 1001 of the tongue of the insulating body 1000, allowing it to mate with the spring contacts of the connector male, releasing static electricity and preventing static noise. The front end of the connecting portion 25 has a chamfer 258 to prevent scratching the spring contacts of the connector male. Figure 4 As shown, all terminals are located on the same side of the latch 23 and the latch 24, that is, they are all located below the latch.

[0029] By electrically connecting the locking mechanism to the metal housing, static electricity within the Type-C female connector can be released, preventing electrostatic interference with signal transmission, improving signal transmission performance, and eliminating noise generated by static electricity during signal transmission.

[0030] By setting a connecting part to connect the two locking devices into one unit, the number of processing steps can be reduced, making processing more convenient and thus reducing costs.

[0031] As a simple variation of this embodiment, the lug 259 may also maintain only electrical contact with the metal casing without being welded together.

[0032] Example 2:

[0033] like Figure 6As shown, in this embodiment, the locking latches 33 and 34 are connected together via the connecting part 35. The difference between this embodiment and Embodiment 1 is that the lug 359 is in the shape of a straight plate, and the lug 359 is welded to the metal shell through its upper end face 3591. By welding the lug 359 to the metal shell, the locking latches 33 and 34 can be electrically connected to the metal shell, the metal shell can be fixed together with the insulating body, and the static electricity on the connector can be released through the metal shell.

[0034] As a simple variation of this embodiment, the lug 359 may also maintain only electrical contact with the metal casing without being welded together.

[0035] Example 3:

[0036] like Figure 7 As shown, in this embodiment, the locking latches 53 and 54 are connected together via the connecting part 55. The difference between this embodiment and Embodiment 1 is that the lug 559 makes electrical contact with the metal housing through a protrusion 5592 on its upper wall surface 5591. In this embodiment, the lug 559 is not welded to the metal housing, but only maintains electrical contact, thereby allowing static electricity on the connector to be released through the housing. By providing the protrusion 5592, the lug 559 can maintain good electrical contact with the metal housing, thus facilitating the release of static electricity.

[0037] Example 4:

[0038] like Figure 8 As shown, in this embodiment, the locking latches 63 and 64 are electrically connected to the metal casing (not shown) through their connecting parts, thereby dissipating static electricity on the connector through the metal casing. In this embodiment, the connecting parts of locking latches 63 and 64 are integrated into a single unit, namely connecting part 65, thus connecting the two locking latches into one unit, facilitating the placement of the locking latches, reducing processing steps, and improving production efficiency. The connecting part 65 is provided with two solder feet 658 for electrical connection with the PCB board, thereby improving the conductivity of the grounding terminal and providing connection strength between the connector and the PCB board. The connecting part 65 is also provided with a lug 659, which is L-shaped and electrically connected to the metal casing through two protrusions 6592 on its upper wall 6591. The lug 659 is provided with a through hole 6593 to facilitate the flow of plastic during injection molding.

[0039] Example 5:

[0040] like Figure 9As shown, in this embodiment, the locking latches 73 and 74 are electrically connected to a metal casing (not shown) via their connecting portions 751 and 752, respectively, thereby dissipating static electricity on the connector through the metal casing. In this embodiment, the connecting portions 751 and 752 of the locking latches 73 and 74 are separately arranged. The connecting portion 751 has solder feet 7518, and the connecting portion 752 has solder feet 7528, for electrical connection with the PCB board, thereby improving the conductivity of the grounding terminal and increasing the connection strength between the connector and the PCB board. The connecting portion 751 also has a lug 7519, which is L-shaped and electrically connected to the metal casing via a protrusion 75192 on its upper wall. The connecting portion 752 also has a lug 7529, which is L-shaped and electrically connected to the metal casing via a protrusion 75292 on its upper wall.
