The current general docking method of the cable plug connector and the socket connector can only be fixed through the structure itself, so it is very easy to fall off due to collision or vibration, especially in the environment where the application environment is prone to vibration or requires stable insertion. Therefore, how to make the cable plug connector stably plugged into the socket connector without the risk of loosening is the problem to be solved by the present invention.

DETAILED DESCRIPTION

[0024] See also Figure 1 and Figure 2 The figure shows a three-dimensional schematic diagram and a three-dimensional exploded schematic diagram of a preferred embodiment of the present invention. The present invention is a double-shell locking clip electrical connector structure, which is used to lock a panel 4 with a socket electrical connector 5. The panel 4 defines a plurality of sockets 40, mainly including: a plug electrical connector 1, a colloid shell 2 and an iron shell 3, wherein the colloid shell 2 defines a main body 20, a covering portion 22 and a pressing portion 24, the main body 20 is used to cover a plug electrical connector 1 with a cable 10, the covering portion 22 is located at the rear end of the main body 20 and is used to cover the cable 10, and the pressing portion 24 extends from the covering portion 22 toward the main body 20 and is located on both sides of the main body 20, and each pressing portion 24 defines a A convex portion 240 protruding toward the main body 20 is defined, the main body 20 defines two corresponding long sides 200 and two corresponding short sides 202 connecting the long sides 200, and each pressing portion 24 corresponds to the position of the short side 202, and the iron shell 3 is sleeved and fixed on the main body 20 and located between the pressing portions 24, wherein the latches 30 extending from both sides of the iron shell 3 correspond to the pressing portions 24, and the latches 30 define a hook 300 and a convex portion 302 corresponding to the convex portion 240, and the hook 300 is buckled with the socket 40 to electrically connect the plug electrical connector 1 to the socket electrical connector 5.

[0025] In addition, the main body 20 defines at least one slot 204 on two corresponding surfaces respectively, and the iron shell 3 is formed by bending so that a dovetail groove 34 is formed on the top surface, and at least one fastener 32 (which can be a spring or a convex bump) corresponding to the slot 204 is provided on the two corresponding surfaces respectively, and the fastener 30 is formed on the iron shell 3 in a tearing manner, and the hook 300 defines two plates 300a, each plate 300a is located on both sides of the front end of the fastener 30, and each plate 300a is bent outward at an angle so that each plate 300a and the fastener 30 form a bending state.

[0026] For reference Figures 3 to 6 The figures are a schematic diagram of the three-dimensional structure of the colloid shell formed on the plug electrical connector of the present invention, a schematic diagram of the three-dimensional structure of the iron shell combined with the colloid shell, a schematic diagram of the three-dimensional structure of the plug electrical connector lock clip connected to the socket electrical connector, and a schematic diagram of the operation structure of the pressing part pressing the latch. The plug electrical connector 1 and the socket electrical connector 5 in this embodiment are both Typc-C electrical connectors. Figure 3 As can be seen in the figure, the plug electrical connector 1 is mainly welded to the cable 10 and then a colloid seat 12 is formed at the welded portion of the plug electrical connector 1 and the cable 10 by insert molding. After the production of the plug electrical connector 1 and the cable 10 is completed, a second insert molding is performed so that the main body 20 and the covering portion 22 in the colloid shell 2 cover the rear end of the plug electrical connector 1, the entire colloid seat 12 and the front end of the cable 10, thereby achieving overall fixation. At the same time, the two corresponding surfaces of the main body 20 are respectively defined with a card slot 204, and the pressing portion 24 extends from the covering portion 22 toward the main body 20 and is located on both sides of the main body 20. Each pressing portion 24 is respectively defined with a convex pressing portion 240 protruding toward the main body 20. It is particularly important that each pressing portion 24 corresponds to the position of the short side 202 of the main body 20, thereby, the operator can use it more in accordance with the inertia of general operation.

[0027] After the insert molding of the colloid shell 2 is completed, the iron shell 3 is sleeved from the position of the plug electrical connector 1 to the direction of the cable 10. At this time, the iron shell 3 is fixed to the main body 20 and located between the pressing parts 24. Then, the fasteners 32 (using springs as an example) provided on the two corresponding surfaces of the iron shell 3 are snapped into the slots 204 to achieve the snap positioning effect. Then, the fasteners 30 on both sides of the iron shell 3 correspond to the pressing parts 24, and the convex parts 302 on the fasteners 30 are adjacent to the position of the hooks 300, and the convex parts 302 correspond to the convex parts 240 on the pressing parts 24. Thus, when the pressing parts 24 on the colloid shell 2 are pressed, the convex parts 240 on the pressing parts 24 directly abut against the convex parts 302 on the fasteners 30, which makes it easier and more accurate to control the hooks 300, and the hooks 300 can be separated from the sockets 40 without pressing too hard (such as Figure 6), and at the same time, the convex portion 302 provided on the buckle 30 is located near the hook 300, so that when the buckle 30 is pressed by the pressing portion 24, the convex portion 302 is located at a position where the elastic strength of the buckle 30 is relatively small, so the deepest pressing range can be achieved with the minimum force. In addition, the anti-slip surface 242 formed on the outer surface of the pressing portion 24 can make the operator feel more operational when pressing and avoid the undesirable operation of the hand slipping during pressing, which is difficult to press. Conversely, the pressing portion 24 can also apply pressure to the buckle 30, so that the hook 300 shrinks inward so that it can be easily inserted into the socket 40 for fastening. The buckled hook 300 is as shown in FIG. Figure 5 It can be seen that the panel 4 is buckled to achieve a locking effect, so that the plug electrical connector 1 can be stably electrically connected to the socket electrical connector 5 without being loosened.

[0028] In addition, the outer surface of the main body 20 is lower than the outer surface of the covering portion 22 to form a height difference, and this height difference is equal to the thickness of the shell 3. Therefore, after the body shell 2 is installed, the overall double-shell locking clip electrical connector structure can be made flatter.
