Description

Technical Field

[0001] The present invention relates to the field of circuit safety technology, and in particular to a fireproof socket, a socket structure and a charging pile. Background Art

[0002] The power-off protection of sockets affects the safety of users' electricity use. In related technologies, sockets often use internal power-off methods to disconnect the power. For example, a built-in electromagnet or other power-off structure disconnects the contact switch in the circuit loop to disconnect the circuit. However, if a fire occurs inside the socket due to an accident such as a short circuit, firstly, the circuit loop inside the socket may not be complete, and the built-in power-off structure may not work properly and reliably disconnect the power. Secondly, even if the socket successfully disconnects the power through the built-in power-off structure, the temperature inside the socket will still be high, which may cause the external circuits such as the plug connected to the socket to melt due to the high temperature, resulting in damage to the plug and other external circuit structures.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The present invention provides a fireproof socket, which is used to prevent an external circuit connected to the socket from burning when the socket catches fire due to a short circuit or other reasons.

[0046] In the embodiment of the present invention, combining 1 and Figure 2 As shown, the fireproof socket 1 includes a socket base 11 and a cover plate 12. The socket base 11 is provided with at least one mounting hole 111 and at least two electrode sockets 112; the cover plate 12 is provided with at least one mounting column 121 and at least two avoidance holes 122; wherein the mounting column 121 has a connection state in which it is inserted into the mounting hole 111, and a fused state in which it is separated from the hole wall of the mounting hole 111 after melting; in the connection state, each avoidance hole 122 is arranged opposite to each electrode socket 112, and the cover plate 12 is connected to the socket base 11; in the fused state, the cover plate 12 is separated from the socket base 11.

[0047] In this embodiment, the socket base 11 is used to receive a plug. The socket base 11 may include a housing and a cavity formed within the housing. The cavity may be used to accommodate and install circuit components of the fire-resistant 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). This ensures that if the fire-resistant socket 1 heats up or catches fire due to a short circuit or other reasons, the socket base 11 will not burn and produce open flames, which could ignite items around the socket base 11 and cause a fire.

[0048] The cover plate 12 is used to block the connection between the plug and the socket base 11. The cover plate 12 is connected to the socket base 11 through the plug-in fit of the mounting post 121 and the mounting hole 111. When the fireproof socket 1 is in normal working conditions, each mounting post 121 is plugged into each mounting hole 111. The plug-in fit between the mounting post 121 and the mounting hole 111 can be achieved by allowing the outer peripheral wall of the mounting post 121 to be in interference fit with the inner peripheral wall of the mounting hole 111. The material of the cover plate 12 can be 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, which is convenient for heat dissipation of the socket base 11. The material of the mounting post 121 can be a material with a low melting point, such as plastic, so that the mounting post 121 can quickly melt and break when the temperature rises or a fire occurs inside the socket base 11 due to a short circuit or other reasons, and separate from the hole wall of the mounting hole 111, so that the cover plate 12 is forced to separate from the socket base 11 due to the elastic effect of the socket base 11, driving the plug to separate from the socket base 11.

[0049] The connection between the mounting post 121 and the cover plate 12 can be achieved through bonding, plugging, or snapping. For example, adhesive can be applied to the cover plate 12, and one end of the mounting post 121 can be connected to the adhesive to achieve the connection between the cover plate 12 and the mounting post 121. Another example is that a hole can be provided in the cover plate 12 to provide an interference fit with the mounting post 121, and the mounting post 121 can be plugged into the hole to achieve the connection between the cover plate 12 and the mounting post 121. It is worth noting that the above two connection methods between the mounting post 121 and the cover plate 12 are merely illustrative and are not the only two limiting methods for connecting the mounting post 121 and the cover plate 12.

[0050] The elastic connection between the socket base 11 and the cover plate 12 can be implemented in the following ways: first, an elastic structure such as an elastic pad, elastic ring, or elastic sleeve is provided on the cover plate 12 or the socket base 11, and the cover plate 12 and the socket base 11 are connected via this elastic structure; second, an elastic layer is provided on one of the cover plate 12 and the socket base 11, which can be a silicone layer, a rubber layer, etc., and the other of the cover plate 12 and the socket base 11 elastically abuts against the elastic layer. It is worth noting that the above two elastic connection methods of the cover plate 12 and the socket base 11 are merely exemplary and are not the only two limiting methods of elastic connection between the cover plate 12 and the socket base 11. Optionally, the elastic connection between the cover plate 12 and the socket base 11 allows the cover plate 12 to be ejected from the socket base 11 when each mounting post 121 enters the fused state from the connected state, driving the plug to separate from the socket base 11, thereby achieving physical isolation between the socket base 11, the plug, and the external circuit.

[0051] When the fireproof socket 1 in the technical solution of this embodiment is under normal conditions, the mounting post 121 is in a connected state, and the cover plate 12 is connected and fixed by plugging the mounting post 121 into the mounting hole 111, and the electrode on the plug is plugged into the electrode plug hole 112 through the avoidance hole 122; under abnormal conditions when the fireproof socket 1 heats up or catches fire due to an accident such as a short circuit, the mounting post 121 is affected by the high temperature environment in the fireproof socket 1 and melts, and the mounting post 121 enters a fused state and separates from the hole wall of the mounting hole 111, so that the cover plate 12 is elastically acted upon and bounces off the socket base 11, and at the same time, the cover plate 12 drives the plug and the socket base 11 to separate, thereby realizing timely disconnection between the external circuit and the fireproof socket 1, and cutting off the current output from the socket to the plug and the external circuit, which can protect the plug and the external circuit while the fireproof socket 1 itself is powered off and gradually cooled.

[0052] In one embodiment of the present invention, Figure 2As shown, the fireproof socket 1 also includes an elastic member 13, which is arranged on the socket base 11; when in the connected state, the end of the elastic member 13 away from the socket base 11 abuts against the cover plate 12, and the cover plate 12 and the socket base 11 cooperate to compress the elastic member 13; when in the fused state, the elastic member 13 pushes the cover plate 12 to separate from the socket base 11.

[0053] In this embodiment, the elastic member 13 is used to bounce the cover plate 12 off the socket base 11 when the mounting post 121 enters the fused state from the connected state. The elastic member 13 can be an elastic pad, an elastic ring, an elastic sleeve, a spring, an arched spring, etc. The material of the elastic member 13 includes but is not limited to silicone, rubber, and metal. When the mounting post 121 is in the connected state, the elastic member 13 is located between the cover plate 12 and the socket base 11 and is in a compressed state, so that when the mounting post 121 enters the fused state due to temperature rise or fire in the socket base 11, the elastic member 13 bounces the cover plate 12 off the socket base 11, and the cover plate 12 drives the plug connected to the socket base 11 to separate from the socket base 11, thereby disconnecting the cover plate 12 and the plug from the socket base 11.

[0054] The setting of the elastic member 13 enables the cover plate 12 to quickly bounce off the socket base 11 under the elastic action of the elastic member 13 when the mounting post 121 enters the fused state from the connected state, so that the plug and the external circuit connected to the plug can be disconnected from the socket base 11 in a timely and rapid manner, thereby achieving power-off and isolation protection for the plug and the external circuit.

[0055] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the socket base 11 is provided with a first limiting hole 113, and the elastic member 13 is partially accommodated and limited in the first limiting hole 113; and / or, the cover plate 12 is provided with a second limiting hole 123, and when in the connected state, the elastic member 13 is partially accommodated in the second limiting hole 123 and abuts against the bottom wall of the second limiting hole 123.

[0056] In this embodiment, the first limiting hole 113 and the second limiting hole 123 are used to limit the elastic member 13 so that the end of the elastic member 13 will not move relative to the cover plate 12 and the mounting column 121, ensuring a reliable and stable elastic connection between the cover plate 12 and the mounting column 121 through the elastic member 13, thereby ensuring that when the mounting column 121 enters the fuse state from the connected state, the elastic member 13 can normally exert its elastic effect, quickly and timely bounce the cover plate 12 away from the socket base 11, and realize timely and rapid disconnection of the plug and the external circuit connected to the plug from the socket base 11.

[0057] It can be understood that when the first limiting hole 113 and the second limiting hole 123 exist at the same time, the opposite ends of the elastic member 13 are respectively limited in the first limiting hole 113 and the second limiting hole 123. In this way, when the cover plate 12 is connected to the socket base 11, both ends of the elastic member 13 will not move relative to the cover plate 12 or the socket base 11, so that the elastic member 13 can exert its elastic effect more reliably and stably.

[0058] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, a hook 1211 is provided at one end of the mounting post 121 away from the cover plate 12; the socket base 11 is provided with a mounting cavity, and at least one mounting hole 111 and at least two electrode sockets 112 are connected to the mounting cavity; when in the connected state, the hook 1211 is located in the mounting cavity and is clamped to the periphery of the mounting hole 111.

[0059] In this embodiment, the hook 1211 is used to engage the cover plate 12 with the socket base 11. The hook 1211 can be integrally formed with the cover plate 12. The hook 1211 passes through the mounting hole 111 and engages with the periphery of the mounting hole 111. The cover plate 12 is elastically connected to the socket base 11 via the elastic member 13. In this way, the cover plate 12 can be firmly and reliably assembled to the socket base 11 without the elastic action of the elastic member 13 causing the cover plate 12 and the mounting hole 111 to shift relative to or separate from each other. This ensures that each avoidance hole 122 is positioned directly opposite each electrode receptacle 112, allowing the electrodes of the plug to smoothly pass through the avoidance holes 122 and engage with the electrode receptacles 112 of the socket base 11.

[0060] Optionally, a clamping block or a clamping protrusion is provided in the mounting hole 111 , and the hook 1211 extends into the mounting hole 111 and clamps with the clamping block or the clamping protrusion, thereby achieving a clamping fit between the hook 1211 and the socket base 11 .

[0061] In one embodiment of the present invention, Figure 2 As shown, the socket base 11 is provided with a limiting groove 114, at least one mounting hole 111 and at least two electrode sockets 112 are opened on the bottom wall of the limiting groove 114; when in the connected state, the cover plate 12 is at least partially accommodated and limited in the limiting groove 114.

[0062] In this embodiment, the retaining grooves 114 are used to retain the cover plate 12 so that when the mounting posts 121 are connected, the cover plate 12 and the elastic member 13 are accommodated and retained within the retaining grooves 114. This prevents the cover plate 12 from protruding from the surface of the socket base 11, making the assembled assembly of the cover plate 12 and the socket base 11 more aesthetically pleasing. Furthermore, the cover plate 12 is less likely to shift relative to the socket base 11, ensuring that each clearance hole 122 is positioned directly opposite each electrode receptacle 112, allowing the electrodes of the plug to smoothly pass through the clearance holes 122 and connect with the electrode receptacles 112 of the socket base 11.

[0063] Secondly, the present invention also proposes a socket structure, such as Figure 2 As shown, the socket structure includes a mounting base 2 and the above-mentioned fireproof socket 1; the mounting base 2 is provided with an assembly opening 221, and the socket base 11 is detachably arranged in the assembly opening 221.

[0064] In this embodiment, the mounting base 2 is used to install and fix the fireproof socket 1. The mounting base 2 is detachably connected to the fireproof socket 1. In this way, the fireproof socket 1 can be used as a replaceable module in the socket structure. When the fireproof socket 1 is damaged due to temperature rise or fire, the fireproof socket 1 can be very conveniently removed from the mounting base 2 to quickly replace the fireproof socket 1.

[0065] The detachable connection between the fireproof socket 1 and the mounting base 2 can be implemented in the following ways: first, the assembly opening 221 of the mounting base 2 matches the fireproof socket 1, the socket base 11 of the fireproof socket 1 is inserted into the assembly opening 221, and the outer peripheral wall of the fireproof socket 1 abuts the inner peripheral wall of the assembly opening 221; second, the outer peripheral wall of the socket base 11 is provided with a plurality of clamping blocks, and the inner peripheral wall of the assembly opening 221 is provided with a plurality of clamping holes, and the socket base 11 is clamped to the inner peripheral wall of the assembly opening 221 through the clamping fit of the clamping blocks and the buckles. It is worth noting that the above two detachable connection methods between the fireproof socket 1 and the mounting base 2 are only for illustrative purposes, and are not the only two limitations on the detachable connection methods of the fireproof socket 1 and the mounting base 2.

[0066] The specific structure of the fireproof socket 1 in this embodiment refers to the above embodiment. Since this socket structure adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0067] In one embodiment of the present invention, Figure 2 As shown, a portion of the socket base 11 protrudes from the assembly opening 221 and is located outside the mounting seat 2 .

[0068] In this embodiment, when part of the socket base 11 protrudes from the assembly opening 221, the socket has a portion exposed on the surface of the socket base 11, so that it is convenient to use force when pulling out the fireproof socket 1 from the assembly opening 221 of the socket base 11, thereby facilitating the disassembly and replacement of the fireproof socket 1.

[0069] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the outer wall of the mounting seat 2 is provided with a mounting surface 21 and an assembly surface 22; the angle between the plane where the mounting surface 21 is located and the plane where the assembly surface 22 is located is defined as α, 0°<α≤90°; the mounting surface 21 is used to install and fix the mounting seat 2, and the assembly port 221 is opened on the assembly surface 22.

[0070] In this embodiment, the mounting surface 21 is a plane for mounting and fixing the mounting base 2. Generally, the mounting surface 21 is a hidden surface after the mounting base 2 is installed and fixed, that is, it is not visible after the mounting base 2 is installed and fixed. The assembly surface 22 is used to assemble the fireproof socket 1. The assembly surface 22 is provided with an assembly opening 221 for accommodating and limiting the position of the fireproof socket 1. When the angle between the plane on which the mounting surface 21 is located and the plane on which the assembly surface 22 is located is greater than 0 degrees and less than or equal to 90 degrees, after the mounting base 2 is installed and fixed via the mounting surface 21, the assembly surface 22 is positioned downward, and the cover plate 12 of the fireproof socket 1 is located on the side of the socket base 11 facing away from the ground. In this way, when each mounting post 121 enters the fused state, the cover plate 12 and the plug are more easily separated from the socket base 11 due to their own gravity. This further ensures that if the socket base 11 heats up or catches fire due to a short circuit or other problem, the cover plate 12 and the plug can be promptly and quickly separated from the socket base 11, thereby promptly disconnecting the plug and the socket base 11.

[0071] In one embodiment of the present invention, Figure 1 As shown, the mounting surface 21 is provided with an operating groove 211 connected to the assembly port 221, and the operating groove 211 is used for the fire-proof socket 1 to connect to the external circuit; the mounting surface 21 is provided with a wire accommodating groove 212, and the wire accommodating groove 212 is used to accommodate wires; the mounting surface 21 is also provided with a wire passing groove 213 for connecting the operating groove 211 and the wire accommodating groove 212.

[0072] In this embodiment, the operating slot 211 is used for connecting the wire to the fireproof socket 1, making it convenient for the operator to connect the wire to the electrode or connector terminal of the fireproof socket 1.

[0073] The wire duct 212 is used to accommodate excess wires to prevent the wires from leaking out of the socket structure and affecting the aesthetics of the socket structure after installation, as well as to isolate and protect the excess wires to prevent the wires from being accidentally damaged. At the same time, when the maintenance personnel pull out the socket base 11, the connected wires do not need to be cut and can be maintained.

[0074] The wire passage 213 is used for passing wires so that the wires can be arranged regularly in the wire passage 213, thereby avoiding messy wiring in the plug structure and also avoiding the problem of electrical signal interference between wires caused by messy wiring.

[0075] Optionally, the assembly port 221, the operating slot 211, the wire passing slot 213 and the wire accommodating slot 212 are connected in sequence, the wires are connected to the fireproof socket 1 in the operating slot 211, and after being regularized by the wire passing slot 213, the remaining wires are uniformly accommodated in the wire accommodating slot 212, so that the wires are arranged in an orderly manner in the mounting seat 2, avoiding the disorder of the wire routing and the interference of electrical signals between the wires.

[0076] Optionally, both the wire receiving slot 212 and the wire passing slot 213 are connected to the assembly opening 221. In this way, when the wire connected to the fireproof socket 1 is long, part of the wire can be arranged back and forth in the wire passing slot 213 and the wire receiving slot 212, so that part of the wire can be accommodated by the wire passing slot 213 and the wire receiving slot 212, thereby avoiding messy routing of the wires and reducing the problem of electrical signal interference between the wires.

[0077] In addition, the present invention also proposes a charging pile, combined with Figure 1 and Figure 2 As shown, the charging pile includes a pile body (not shown) and the socket structure in the above embodiment, and the mounting base 2 of the socket structure is provided on the pile body.

[0078] In this embodiment, the charging pile charges robots, electric vehicles, electric toys, power banks and other devices or equipment that need to be charged through the socket structure. The mounting seat 2 is fixed on the pile body through the mounting surface 21, and the assembly surface 22 is set downward. The cover plate 12 of the fireproof socket 1 is located on the side of the socket base 11 facing away from the ground. In this way, when each mounting column 121 enters the melting state, the cover plate 12 and the plug are affected by their own gravity and are more likely to be separated from the socket base 11. This further ensures that when the socket base 11 heats up or catches fire due to problems such as short circuits, the cover plate 12 and the plug can be separated from the socket base 11 in a timely and rapid manner, so that the plug and the socket base 11 are disconnected in time.

[0079] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, within the scope of the present invention are included in the patent protection scope of the present invention.
