The invention provides a fireproof socket which is used for preventing an external circuit connected with the socket from being burnt when the socket is on fire due to short circuit and the like.

In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the fire-proof socket 1 includes a socket base 11 and a cover plate 12, wherein the socket base 11 is provided with at least one mounting hole 111 and at least two electrode insertion holes 112; the cover plate 12 is provided with at least one mounting post 121 and at least two avoiding holes 122; the mounting column 121 has a connection state of being inserted into the mounting hole 111 and a fusing state of being separated from the wall of the mounting hole 111 after being melted; in the connection state, each avoiding hole 122 is arranged opposite to each electrode jack 112, and the cover plate 12 is connected with the socket base body 11; in the fused state, the cover plate 12 is detached from the socket base 11.

In the present embodiment, the socket base 11 is used for plugging a plug, and the socket base 11 may include a housing and a cavity formed in the housing, and the cavity may be used for accommodating and mounting circuit components of the fireproof plug, such as a circuit board. The socket base 11 may be made of a flame retardant and high temperature resistant material such as PC (Polycarbonate), so that when the fire-proof socket 1 is heated or ignited due to a short circuit or the like, the socket base 11 does not burn to generate an open fire, which may cause the ignition of the objects around the socket base 11 and cause a fire.

The cover plate 12 is used to block the connection of the plug and the socket base 11, and the cover plate 12 is connected with the socket base 11 through the plug-in fit of the mounting posts 121 and the mounting holes 111. When the fire socket 1 is in a normal condition of normal operation, each mounting post 121 is inserted into each mounting hole 111. The insertion of the mounting post 121 into the mounting hole 111 can be achieved by allowing the outer peripheral wall of the mounting post 121 to be in interference contact with the inner peripheral wall of the mounting hole 111. The cover plate 12 may be made of a flame retardant and heat absorbing material, so that the cover plate 12 will not melt or burn due to the high temperature on the socket base 11, and the cover plate 12 will absorb part of the heat on the socket base 11, thereby facilitating the heat dissipation of the socket base 11. The mounting posts 121 may be made of a material with a low melting point, such as plastic, so that the mounting posts 121 can be melted and broken rapidly when heated or ignited for short circuit in the socket base 11, and separated from the hole walls of the mounting holes 111, so that the cover plate 12 is forced by the elastic action of the socket base 11 to drive the plug to be separated from the socket base 11.

The connection between the mounting post 121 and the cover plate 12 can be implemented by bonding, inserting, clamping, etc., for example, an adhesive is coated on the cover plate 12, and one end of the mounting post 121 is connected with the adhesive, so as to connect the cover plate 12 and the mounting post 121. For another example, a hole in interference fit with the mounting post 121 is formed in the cover plate 12, and the mounting post 121 is inserted into the hole to connect the cover plate 12 and the mounting post 121. It is worth pointing out that the above two connection manners between the mounting post 121 and the cover plate 12 are only exemplary, and are not the only limitations on the connection manners between the mounting post 121 and the cover plate 12.

The elastic connection between the socket base 11 and the cover plate 12 can be implemented by: firstly, elastic structures such as an elastic pad, an elastic ring and an elastic sleeve are arranged on the cover plate 12 or the socket base body 11, and the cover plate 12 and the socket base body 11 are connected through the elastic structures; secondly, an elastic layer is arranged on one of the cover plate 12 and the socket base 11, the elastic layer can be a silica gel layer, a rubber layer and the like, and the other of the cover plate 12 and the socket base 11 is elastically abutted with the elastic layer. It should be noted that the two elastic connection manners of the cover plate 12 and the socket base 11 are only exemplary, and are not the only limitations on the elastic connection manner of the cover plate 12 and the socket base 11. Optionally, the cover plate 12 is elastically connected to the socket base 11, so that when each mounting post 121 enters the fusing state from the connection state, the cover plate 12 can be ejected from the socket base 11, and drives the plug to be separated from the socket base 11, thereby achieving physical isolation between the socket base 11 and the plug and an external circuit.

In the technical scheme of the embodiment, when the fire-proof socket 1 is in a normal state, the mounting column 121 is in a connection state, the cover plate 12 is connected and fixed by the insertion and the matching of the mounting column 121 and the mounting hole 111, and the electrode on the plug passes through the avoiding hole 122 and is inserted into the electrode insertion hole 112; under the unusual condition that fire prevention socket 1 heaies up or catches fire because of accidents such as short circuit, erection column 121 receives the high temperature environment influence in fire prevention socket 1 and melts, erection column 121 gets into fusing state and breaks away from with the pore wall of mounting hole 111 mutually, thereby make apron 12 bounce off socket base body 11 because of receiving socket base body 11's elastic action, apron 12 drives simultaneously and breaks away from with socket base body 11 mutually with the plug, so realize timely disconnected of external circuit and fire prevention socket 1, and cut off the current output of socket to plug and external circuit, when can make fire prevention socket 1 self outage and cool down gradually, protection plug and external circuit.

The elastic element 13 may be an elastic pad, an elastic ring, an elastic sleeve, a spring, an arched elastic sheet, etc., and the material of the elastic element 13 includes but is not limited to silicone, rubber, and metal. When the mounting post 121 is in a connection state, the elastic element 13 is located between the cover plate 12 and the socket base body 11 and is in a compression state, so that when the mounting post 121 enters a fusing state due to temperature rise or fire in the socket base body 11, the cover plate 12 is bounced off from the socket base body 11 by the elastic element 13, the cover plate 12 drives a plug inserted into the socket base body 11 to be separated from the socket base body 11 together, and disconnection of the cover plate 12 and the plug from the socket base body 11 is achieved.

Due to the arrangement of the elastic piece 13, when the mounting column 121 enters the fusing state from the connection state, the cover plate 12 can be rapidly ejected away from the socket base body 11 under the elastic action of the elastic piece 13, so that the plug and an external circuit connected with the plug can be timely and rapidly disconnected from the socket base body 11, and the power failure and isolation protection of the plug and the external circuit are realized.

In this embodiment, the first limiting hole 113 and the second limiting hole 123 are used for limiting the elastic element 13, so that the end of the elastic element 13 cannot move relative to the cover plate 12 and the mounting post 121, and reliable and stable elastic connection between the cover plate 12 and the mounting post 121 through the elastic element 13 is ensured, so that when the mounting post 121 enters the fusing state from the connection state, the elastic element 13 can normally exert its elastic function, the cover plate 12 is quickly and timely ejected away from the socket base 11, and the plug and the external circuit connected to the plug are timely and quickly disconnected from the socket base 11.

It can be understood that when the first limiting hole 113 and the second limiting hole 123 exist simultaneously, the two opposite ends of the elastic element 13 are respectively limited in the first limiting hole 113 and the second limiting hole 123, so that when the cover plate 12 is connected with the socket base 11, the two ends of the elastic element 13 will not move relative to the cover plate 12 or the socket base 11, and the elastic element 13 can exert its elastic function more reliably and stably.

Optionally, a latch or a latch protrusion is disposed in the mounting hole 111, and the hook 1211 extends into the mounting hole 111 and latches with the latch or the latch protrusion, so as to implement a latching fit of the hook 1211 with the socket base 11.
