[0002] Traditional electrical accessories that need to be connected to a power cord, such as power sockets, circuit breakers, switches, etc., usually use screws to press the power cord terminals onto the wiring copper sheets. This connection structure is not only complicated to operate and has low wiring efficiency, but the wiring quality is highly dependent on the operator's personal professionalism, proficiency and concentration. For example, when ordinary users purchase a power socket and install it themselves, the power cord terminals of the socket are often poorly connected, resulting in high resistance at the power cord connection. Long-term use will cause heat at the power cord connection to damage the socket, and in severe cases, it may even cause serious accidents such as fire. Summary of the invention

[0007] In the quick connection device of the present invention, the elastic member includes a second bend, the second bend connects the supporting edge and the extending edge of the elastic member, and the extending edge is electrically connected to the conductive member.

[0008] In the quick connection device of the present invention, the elastic inclined arm of the elastic member includes a third bend for increasing the elastic clamping force, and the third bend is bent in a direction that increases a wedge angle formed by the elastic inclined arm and the conductive member.

[0026] The present invention will be described in detail below in conjunction with typical embodiments and the accompanying drawings. The same reference numerals in each figure indicate the same or similar parts. Although the specification discloses typical embodiments, there may be other embodiments that do not depart from the spirit and scope of the present invention without changing the embodiments of the specification. The following detailed description does not limit the present invention, and the scope of protection of the present invention is defined by the claims and their equivalent technical solutions.

[0027] like Figures 1 to 3 As shown, the quick connection device of the present invention comprises a housing 101, a conductive member 2, an elastic member 3 and a clamp release mechanism. The structure of the housing 101 can be a single housing or a combined housing consisting of an upper cover and a lower cover.

[0028] The conductive member 2 is installed near the wire insertion port 1011 of the housing 101 to ensure that after the wire 4 terminal is inserted through the wire insertion port 1011, the side surface of the wire 4 contacts and cooperates with the surface of the conductive member 2 to achieve electrical connection. The conductive member 2 can be a sheet structure or other structure that meets the needs, such as a columnar structure.

[0029] The elastic member 3 is arranged in the housing 101 opposite to the conductive member 2. The elastic member 3 includes an elastic tilted arm, which is wedge-shaped with the conductive member 2 along the insertion direction of the wire insertion port 1011, and the edge of the elastic tilted arm is elastically pressed on the conductive member 2 to ensure that after the connection end of the wire 4 is inserted through the wire insertion port 1011, the edge of the elastic tilted arm clamps the wire 4 on the conductive member 2.

[0030] like Figure 2 , Figure 3 As shown, in the present embodiment, the elastic member 3 adopts three bending structures: the first bend 31 generates an elastic clamping force and is used for positioning the elastic member 3, the first bend 31 connects the elastic inclined arm and the supporting edge of the elastic member 3, the supporting edge is supported on the wall of the shell 101, and the first bend 31 is supported on the corresponding bending mounting position of the shell 101; the second bend 32 connects the supporting edge and the extension edge of the elastic member 3, the extension edge is electrically connected to the conductive member 2, thereby increasing the electrical connection contact area between the conductive member and the wire 4, and meeting the load requirements of large current electrical accessories; the third bend 33 is arranged on the elastic inclined arm, for increasing the elastic clamping force on the wire 4, the third bend 33 is bent in a direction that increases the wedge angle formed by the elastic inclined arm and the conductive member 2, and when the wire 4 is inserted, the elastic inclined arm undergoes elastic deformation at the third bend 33, which can increase the elastic clamping force of the elastic inclined arm on the wire 4.

[0031] In other embodiments, the third bend 33 may not be provided, and the purpose of the present invention can still be achieved.

[0032] In other embodiments, the second bend 32 may not be provided, and the purpose of the present invention can still be achieved.

[0033] In other embodiments, only the first bend 31 may be provided, and the purpose of the present invention may also be achieved.

[0034] In other embodiments, the elastic member 3 may only be an elastic tilting arm, and the rear end of the elastic tilting arm is connected and fixed to the housing 101 , which can also achieve the purpose of the present invention.

[0035] like Figure 4 , Figure 5As shown, in order to increase the contact area between the conductive member 2 and the wire 4 and improve the conductive area between the conductive member 2 and the wire 4, an arc surface 22 that matches the surface of the wire 4 is provided on the surface of the conductive member 2 that matches the wire 4. In this way, the line contact between the conductive member 2 and the wire 4 when the electrical connection surface is a plane can be improved to surface contact, which can greatly improve the conductive area between the conductive member 2 and the wire 4. The radius of the arc surface 22 can adopt the radius of the most commonly used wire diameter, such as 1 mm for a wire with a wire diameter of 2 mm, or the radius of 0.9 mm for a wire diameter of 1.8 mm, which is an intermediate value of the commonly used wire diameter of 1.5 mm to 2.1 mm, or the radius of the arc surface 22 can be determined by a radius of a smaller wire diameter (such as 1.5 mm). In this way, when the radius of the wire diameter actually used is greater than the radius of the arc surface 22, the wire 4 generates two contact lines at both ends of the arc surface 22 of the conductive member 2, which can also improve the conductive area between the conductive member 2 and the wire 4.

[0036] In other embodiments, the conductive member 2 is not provided with the arc surface 22 and the purpose of the present invention can also be achieved.

[0037] The unclamping mechanism is arranged on both sides of the conductive member 2 opposite to the elastic member 3. The unclamping mechanism is arranged on the housing 101. By unclamping the mechanism, the clamping of the elastic inclined arm of the elastic member 3 on the wire 4 can be released or released with the help of an external tool.

[0038] like Figure 2 , Figure 3 As shown, in this embodiment, the clamping release mechanism adopts the following structure: the clamping release mechanism includes a button 1, which includes a hinged end 11 and a pushing end 12. The button 1 is hinged to the housing 101 through its hinged end 11, and cooperates with the elastic inclined arm of the elastic member 3 through its pushing end 12. When the button 1 is pressed, the pushing end 12 lifts the elastic inclined arm to release the clamping of the edge of the elastic inclined arm on the wire 4.

[0039] In other embodiments, the clamping release mechanism can adopt the following structure: the clamping release mechanism includes a button, which includes a pressing guide portion (including a pressing surface and a guide portion) and a pushing top portion. The pressing guide portion cooperates with the guide groove of the shell 101 to realize the movement and guidance of the button, and the pushing top portion cooperates with the elastic inclined arm of the elastic member 3. When the button is pressed, the pushing top portion lifts the elastic inclined arm to release the clamping of the edge of the elastic inclined arm on the wire 4.

[0040] In other embodiments, the clamping release mechanism can adopt the following structure: the clamping release mechanism includes an operating hole arranged on the shell 101, through which a pushing tool (such as a small screwdriver, etc.) can be used to lift the elastic inclined arm of the elastic member 3 to release the clamping of the edge of the elastic inclined arm on the wire 4.

[0041] like Figure 1 , Figure 6 As shown, the electrical accessory 100 of the present invention adopts the above-mentioned quick wiring device of the present invention.

[0042] In this embodiment, the power socket using the quick wiring device of the present invention is provided with a ground wire jack, a live wire jack and a neutral wire jack, and a live wire jack and a neutral wire jack are also extended.

[0043] In other embodiments, the wire jacks of the socket are arranged as needed, for example, only a ground wire jack, a live wire jack and a neutral wire jack are arranged, which can also achieve the purpose of the present invention.

[0044] In other embodiments, the electrical accessories of the present invention may include but are not limited to circuit breakers, power switches, etc.

[0045] The above description has described various embodiments in conjunction with the accompanying drawings. However, it is obvious that various modifications and changes can be made without departing from the scope of the claims of the present invention to obtain other embodiments, and the purpose of the present invention can also be achieved. In conjunction with the embodiments disclosed in the description of the present invention, other embodiments that achieve the purpose of the present invention will be obvious to those skilled in the art.
