DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1 to 5 As shown, the LED display indoor power quick connector of the present invention includes a male connector 1 and a female connector 7. Specifically, the male connector 1 serves as the installation body for the internal power connection, and the female connector 7 serves as the installation body for the external power connection. The male connector 1 and the female connector 7 are connected in a plug-in manner. In order to facilitate the connection, Figure 1 、 Figure 2 As shown, a plug-in cavity 2 is provided at the front end of the male connector 1, and a group of conductive pin components 6 are provided in the plug-in cavity 2. Figure 3 As shown, the conductive pin assembly 6 comprises a live conductive pin 6-1, a ground conductive pin 6-2, and a neutral conductive pin 6-3. When in use, the live conductive pin 6-1 serves as a live connection component for the internal power line, the ground conductive pin 6-2 serves as a ground connection component for the internal power line, and the neutral conductive pin 6-3 serves as a neutral connection component for the internal power line.

[0023] like Figure 4 As shown, the front end of the female connector 7 is provided with a docking arm 8 that matches the plug cavity 2. A conductive plug hole assembly 5 is provided on the docking arm 8. Figure 5 As shown, the conductive socket assembly 5 comprises a live wire conductive hole 5-1, a ground wire conductive hole 5-2, and a neutral wire conductive hole 5-3. During use, the live wire conductive hole 5-1 serves as the live wire connection component for the external power cord, the ground wire conductive hole 5-2 serves as the ground wire connection component for the external power cord, and the neutral wire conductive hole 5-3 serves as the neutral wire connection component for the external power cord. When the male connector 1 and the female connector 7 are mated, the live wire conductive pin 6-1 plugs into the live wire conductive hole 5-1, the ground wire conductive pin 6-2 plugs into the ground wire conductive hole 5-2, and the neutral wire conductive pin 6-3 plugs into the neutral wire conductive hole 5-3.

[0024] like Figure 3 and Figure 5As shown, in this embodiment, the cavity of the plug-in cavity 2 and the insert arm of the docking arm 8 are both in the shape of a triangle. In actual use, the cavity of the plug-in cavity 2 and the insert arm of the docking arm 8 can also be configured to match different shapes as needed, such as rectangle, square, trapezoid, triangle, and other different shapes. At the same time, in order to protect the power cord and prevent damage to the connection between the power cord and the male and female connectors during use, a wire protection sleeve 4 is provided on both the male connector 1 and the female connector 7. The wire protection sleeve 4 can be a hard sleeve or a soft sleeve, and can be adjusted according to the needs of use.

[0025] like Figure 1 As shown, to achieve rapid docking and fast fixation between the male connector 1 and the female connector 7, one or more elastic locking devices 3 are provided on the male connector 1, and one or more clamping heads 9 that match the elastic locking devices 3 are provided on the female connector 7. During use, the elastic locking devices 3 are engaged with the clamping heads 9. In this embodiment, the number of elastic locking devices 3 and the clamping heads 9 is preferably set to two, and the two elastic locking devices 3 are symmetrically arranged on the insertion cavity 2 of the male connector 1, and the two clamping heads 9 are symmetrically arranged on the female connector 7, and the arrangement positions of the elastic locking devices 3 and the clamping heads 9 need to maintain a one-to-one correspondence.

[0026] Among them, Figure 2 As shown, the elastic locking device 3 is composed of a support block 3-2, an unlocking pressure arm 3-1 provided at one end of the support block 3-2, and a claw 3-3 provided at the other end of the support block 3-2. The support block 3-2 is fixed to the male connector 1. During installation, the support block 3-2 is fixed to the plug-in cavity 2 of the male connector 1. During use, the clamping head 9 is engaged with the claw 3-3. The plug-in surface of the clamping head 9 and the inner claw surface of the claw 3-3 are both inclined surfaces to facilitate the engagement of the clamping head 9 with the claw 3-3.

[0027] During use, the docking arm 8 of the female connector 7 is inserted into the insertion cavity 2 of the male connector 1, and after the conductive pin assembly 6 is inserted into the conductive insertion hole assembly 5, the female connector 7 or the male connector 1 is pushed so that the insertion surface of the clamping head 9 contacts the inclined surface of the inner claw surface of the clamping claw 3-3. Continuing to push the clamping head 9 can snap into the clamping claw 3-3, thus achieving a quick connection and fixation of the male connector 1 and the female connector 7. When it is necessary to separate the female connector 7 from the male connector 1, it is only necessary to press the unlocking pressure arm 3-1 to expand the clamping claw 3-3 outward. At this time, the clamping claw 3-3 can be disengaged from the clamping head 9, and the docking arm 8 of the female connector 7 can be pulled out of the insertion cavity 2 of the male connector 1, achieving a quick separation of the power connector. In this way, the male connector 1 and the female connector 7 can be quickly docked, fixed, and separated, which effectively solves the problem that the existing LED display power docking cable is not firmly connected, easily falls off, and is inconvenient to separate during use.

[0028] As described above, the present invention can be well implemented.
