[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] See also Figure 1-6 The utility model provides an embodiment: a DC charging socket with quick maintenance and signal integration, including a front end portion 1, a fixing member 2 is provided on the back of the front end portion 1, the fixing member 2 includes a connecting sleeve 13 and a cable connecting seat 16, the front end portion 1 includes a connecting plate 17 and a connecting ring seat 18, the outer walls of the connecting ring seat 18 are all provided with a snap seat 14, the outer walls of the connecting sleeve seat 13 are all provided with a snap groove 15, and the snap seat 14 is snapped into the inside of the snap groove 15, the interior of the connecting plate 17 is provided with a female terminal 4, the connecting ring seat A signal terminal 3 is provided inside 18, one end of the female terminal 4 is connected to a protective sleeve 8 by an external snap-fit, and the other end of the female terminal 4 is connected to a connecting sleeve 7 by an external snap-fit. The female terminal 4 includes a crown spring assembly 12 and a copper sleeve 10, and the copper sleeve 10 is located at one end of the crown spring assembly 12. A connecting groove 9 is provided on the outer wall of the crown spring assembly 12. The crown spring assembly 12 includes a terminal sleeve 5 and a flanged crown spring 6, and the flanged crown spring 6 is combined with the terminal sleeve 5 by riveting. The crown spring assembly 12 is a detachable structure, which is convenient for quick replacement of damaged or worn terminals.
[0024] See also Figure 2 、 3 The signal terminal 3 is integrated uniformly by the PCB circuit board to improve signal stability.
[0025] Working principle: During use, since the end of the crown spring assembly 12 of the charging socket is fixed to the copper sleeve 10 by the screw 11, the crown spring assembly 12 can be quickly disassembled and replaced, which improves convenience. When the front end 1 of the charging socket is connected to the fixing part 2, its connecting ring seat 18 is partially inserted into the connecting sleeve seat 13, and is snapped into the snap groove 15 through the snap seat 14, so as to realize the quick connection between the front end 1 and the fixing part 2, thereby forming a DC charging socket. When the socket terminal of the front end 1 is damaged or worn, it is only necessary to remove the protective cover 8 and the female terminal 4, and then remove the screw 11 to independently remove the crown spring assembly 12, thereby facilitating the replacement of the terminal sleeve 5 and the flanging crown spring 6. There is no need to additionally separate the front end 1 and the fixing part 2, and there is no need to replace the entire cable, which reduces after-sales costs and reduces component replacement losses. The process is simple and intuitive, and is easy to operate.
[0026] The flanged crown spring 6 of the charging socket is combined with the terminal sleeve 5 by riveting, which increases the cross-sectional area of the terminal, allowing the maximum charging power of the charging socket to reach 600A (15MIN), significantly reducing the charging time. The terminals and cables are ultrasonically welded, which has very good conductivity.
[0027] The signal terminal 3 of the charging socket is uniformly integrated by the PCB circuit board;
[0028] The protective sleeve 8 and the connecting sleeve 7 of the charging socket are both connected to the female terminal 4 by snaps, which not only provide protection but also facilitate disassembly and replacement, thereby improving flexibility.
[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
