The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 7 and 9, the pair of inserts of the LED display device of the present embodiment includes: a power supply female terminal 10, a switching member 20, and a blocking member 30. The power supply female terminal 10 includes a base 11, and a first current-carrying portion 12 and a second current-carrying portion 13 provided in the base 11 at an interval. The switch member 20 includes a connection conductor 21 movably disposed in the base 11 and a control key 22 for driving the connection conductor 21 to move. The control key 22 is in the first control position to drive the connecting conductor 21 in the conducting position in which the first conducting portion 12 and the second conducting portion 13 are conducting, and the control key 22 is in the second control position to drive the connecting conductor 21 in the disconnecting position in which the first conducting portion 12 and the second conducting portion 13 are disconnecting. The blocking member 30 is movably disposed through the base 11 and has a first blocking position for locking the control key 22 at the second control position and a second blocking position for blocking the external plug 40 from entering the base 11. When the external plug 40 is inserted into the base 11 and electrically connected to the second conducting portion 13, the external plug 40 keeps the blocking member 30 at the first blocking position, and when the control key 22 is located at the first control position, the control key 22 keeps the blocking member 30 at the second blocking position.

By applying the technical scheme of the embodiment, the plug-in units of the LED display device can be mounted at the side edges of two adjacent display units, the first electrifying part 12 is connected with the power supply unit of one display unit, and the second electrifying part 13 is connected with the power supply unit of the other display unit. The blocking member 30 is movably disposed through the base 11 and has a first blocking position for locking the control key 22 at the second control position and a second blocking position for blocking the external plug 40 from entering the base 11. When the external plug 40 is inserted into the base 11 and electrically connected to the second conducting portion 13, the external plug 40 keeps the blocking member 30 at the first blocking position, and when the control key 22 is located at the first control position, the control key 22 keeps the blocking member 30 at the second blocking position. In this way, the connection conductor 21 is always kept in a separated state in which the first current carrying portion 12 and the second current carrying portion 13 are disconnected, and further, current is not conducted between the adjacent two display units. In this way, the on state and the off state of the first conducting part 12 and the second conducting part 13 of the power supply female terminal 10 can be known to be in the off state without manual identification, thereby avoiding manual identification errors or misoperation in the on state, and further reducing the possibility of accidents. Therefore, the technical scheme of the embodiment solves the problem that the socket is conducted by the misoperation of the socket in the related art. The switch member 20 of the present embodiment is preferably a boat type switch.

Thus, when the external plug 40 is not inserted into the base 11, the second blocking section 32 is always kept at the second blocking position under the elastic force of the elastic member 50, so as to prevent the external plug 40 from entering the base 11. The elastic member 50 is preferably a spring.

As shown in fig. 3, 4 and 7, in order to facilitate the installation of the stopper 30 and the elastic member 50 in the base 11, the mount 14 is provided in the base 11. The blocking member 30 is movably disposed through the mounting seat 14, and the elastic member 50 is disposed in the mounting seat 14. In order to prevent the mounting seat 14 from interfering with the blocking member 30 during the switching of the blocking member 30 between the first blocking position and the second blocking position, the mounting seat 14 is provided with a first notch 141 that is open to the first blocking section 31 and a second notch 142 that is open to the second blocking section 32.

The blocking member 30 further comprises a guiding ring portion 33 in guiding engagement with the receiving cavity 143, the guiding ring portion 33 being connected between the first blocking section 31 and the second blocking section 32. In this way, during the switching process of the blocking member 30 between the first blocking position and the second blocking position, the guide ring moves along the cavity wall of the accommodating cavity 143, so that the first blocking section 31 and the second blocking section 32 can both move along the predetermined moving track, and the switching process of the blocking member 30 is smooth. Preferably, the receiving cavity 143 has a semi-circular concave surface for guiding engagement with the guide ring.

Thus, the blocking member 30 and the elastic member 50 are prevented from being separated from the receiving chamber 143.

As shown in fig. 3 and 7, an end of the first blocking section 31 facing the control key 22 is a first ball 311, and an end of the second blocking section 32 facing the outer plug 40 is a second ball 321. When the external plug 40 is inserted into the base 11 and electrically connected to the second conducting portion 13, the outer side surface of the external plug 40 contacts the second ball 321 at a point, so as to push the second blocking section 32 to drive the first blocking section 31 to be inserted into the blocking hole 222. When the control key 22 is located at the first control position, the outer side surface of the key body 221 is in point-surface contact with the first ball head 311, so as to push the first blocking section 31 to drive the second blocking section 32 to move.

As shown in fig. 5 to 9, the LED display device of the present embodiment includes a first display unit 61, a second display unit 62, and a plug-in unit, where the first display unit 61 and the second display unit 62 are disposed adjacent to each other, and the plug-in unit is the plug-in unit of the LED display device. The plug-in of the LED display device can solve the problem that the socket is conducted by misoperation in the related art, so that the LED display device with the plug-in can solve the same technical problem. The power supply female terminal 10 of the plug-in unit is arranged at the adjacent side of the first display unit 61 and the second display unit 62, the first electrifying part 12 is connected with the power supply part of the first display unit 61, and the second electrifying part 13 is connected with the power supply part of the second display unit 62.

When only the control key 22 is located at the second control position, the blocking hole 222 faces the first blocking section 31, and at this time, if the external plug 40 presses the second blocking section 32, the blocking member 30 can move to the position where the first blocking section 31 is inserted into the blocking hole 222. When no external plug 40 is inserted into the base 11, the control key 22 can be freely switched between the second control position and the first control position; when the external plug 40 is inserted, only the external plug 40 is allowed to supply power to the second electrifying part 13, and the power supply to the first electrifying part 12 is not allowed; the misoperation caused by manual power-on of the first power-on part 12 and the second power-on part 13 is prevented.
