Abstract
Description
Technical Field
[0001] This utility model relates to the field of power connector technology, and specifically to a power connector that is securely installed. Background Technology
[0002] As a core component for power transmission in electronic devices, the reliability of the assembly between the conductive terminals and the insulating shell of a power connector directly affects the overall performance of the connector. In traditional power connector designs, the conductive terminals are typically formed by folding together two symmetrically distributed conductive metal sheets, left and right. For example... Figure 1 As shown, the tops of the two conductive metal sheets are formed by a stamping process to create an upward-curving anti-retraction elastic sheet 1. After the terminal is inserted into the insulating housing, the elastic sheet is inserted into the preset limiting hole on the top of the housing through elastic deformation, so as to achieve axial fixation between the terminal and the housing.
[0003] However, the aforementioned traditional structure has significant limitations: First, due to the molding method of the anti-reverse elastic sheet 1, the conductive metal sheet needs to reserve sufficient width to accommodate the folding space of the two symmetrical pieces, making it difficult to compress the lateral dimensions of the terminal; Second, when the internal cavity of the insulating housing can only provide installation space for a single-sided conductive metal sheet due to miniaturization requirements, the symmetrically designed anti-reverse elastic sheet 1 cannot be effectively engaged due to the lack of opposing support structures, and may even lose its anti-reverse function due to plastic deformation caused by unilateral force on the elastic sheet. In addition, the two-piece folding design requires additional cutting and bending processes for the metal sheet, leading to increased production costs and reduced assembly efficiency.

[0028] The present invention will be further described in conjunction with the following embodiments.

[0033] Specifically, in this embodiment, when installing the conductive metal part to the housing 2, the plug part 42 enters from the fixing channel 22 and moves towards the plug groove 21. During the process of the plug part 42 moving to the plug groove 21, the top of the fixing part 41 enters the fixing groove 51 from the inlet 6. When the anti-reverse spring 43 passes through the inlet 6, since the width of the inlet 6 and the width of the fixing groove 51 are both smaller than the width of the anti-reverse groove 52, the anti-reverse spring 43 deforms until it enters the anti-reverse groove 52.
