DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0021] See also Figure 1-8 , the utility model provides an embodiment: a fixing structure of an electrical connector, including a plug housing 1 and a mating housing 2 that matches the plug housing 1, and the end of the plug housing 1 away from the mating housing 2 is connected to a plug connector 4; the plug connector 4 includes a shell 40, a retaining frame 42 installed in the shell 40, and a conductive plate 41 is provided in the retaining frame 42; one end of the conductive plate 41 is connected to a conductive sheet 43, and after the plug housing 1 is mated with the mating housing 2, the other side of the conductive plate 41 is connected to the electrode sheet in the mating housing 2; a support portion 45 is provided inside the retaining frame 42, and a first fastener 46 is provided at one end of the support portion 45, and a second fastener 47 is provided at the other end of the support portion 45.

[0022] To sum up, after the conductive plate 41 is connected to the retaining frame 42, the cooperation between the two first fasteners 46 and the second fasteners 47 and the support portion 45 can limit the conductive plate 41 from sliding backward inside the retaining frame 42 and swinging left and right in the middle of the support portion 45, thereby ensuring that the conductive plate can be stably and reliably located in the retaining frame.

[0023] Based on this, when the plug housing 1 is connected to the mating housing 2, when the electrode sheet inside the mating housing 2 contacts the conductive plate 41, since the position of the conductive plate 41 is stable and reliable, there will be no sparking between the electrode sheet and the conductive plate 41 due to displacement of the conductive plate, thereby ensuring the reliability of the circuit connection.

[0024] Furthermore, after the conductive plate 41 is inserted into the retaining frame 42, the first fastener 46 and the second fastener 47 are pressed against the conductive plate 41 from both sides of the conductive plate 41. Therefore, the two fasteners can be used to fix the conductive plate 41 on both sides to ensure the stability of the conductive plate 41 after installation. In particular, it can avoid the problem of the conductive plate 41 moving backward during the connection process between the plug housing 1 and the mating housing 2, that is, the conductive plate 41 moves toward the end away from the mating housing 2.

[0025] Furthermore, since the conductive plate 41 is further provided with a stepped surface 44 , and the first fastener 46 and the second fastener 47 both abut against the stepped surface 44 , the conductive plate 41 can be further prevented from moving backward.

[0026] Specifically, the first fastener 46 and the second fastener 47 have the same structure; and the first fastener 46 includes a first interference portion and a second interference portion; therefore, both fasteners have two interference portions, so the four interference portions can be used to fix the conductive plate 41 from the top, bottom, left and right of the conductive plate 41 at the same time to ensure that the conductive plate 41 will not be displaced after installation.

[0027] On the basis of the above solution, the retaining frame 42 is further provided with an outer cover 48, and is connected to the retaining frame 42 through the outer cover 48 to fix the conductive plate 41 in the retaining frame 42. Therefore, the outer cover 48 is covered on the retaining frame 42 to reliably fix the conductive plate 41, thereby preventing the conductive plate 41 from being pulled out when the plug housing 1 and the mating housing 2 are separated.

[0028] Specifically, a central portion of the outer cover 48 is provided with a latching slot 411 for latching onto the conductive plate 41. Furthermore, the outer cover 48 is adapted to engage with a latching pin 49 provided on the retaining frame 42 via a latching slot 410. This ensures that the conductive plate 41 is securely positioned within the retaining frame 42, thereby ensuring safe and stable operation of the circuit.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
