[0062] This embodiment provides a quick wiring device, which can realize the quick plugging and unplugging of wires without the aid of auxiliary tools, reduces the difficulty of connecting and disconnecting wires, and improves the efficiency of connecting and disconnecting wires.

[0063] Specifically, as Figures 1 - 7 shown, the quick wiring device includes a housing 100, a quick plug terminal 200, a button 300, and a second elastic member 400.

[0064] Among them, a terminal installation space is provided inside the housing 100. The terminal installation space is used to install the quick-insert terminal 200. A wire insertion hole 111 and a button assembly hole 112 communicating with the terminal installation space are provided on the housing 100. An external wire can be inserted into the housing 100 from the wire insertion hole 111 and enter the terminal installation space to be connected to the quick-insert terminal 200. The quick-insert terminal 200 includes a conductive plate 210 and a first elastic member 220. A clamping plate 211 is provided at one end of the conductive plate 210 close to the wire insertion hole 111. One end of the first elastic member 220 is connected to the conductive plate 210, and the other end can elastically approach or move away from the clamping plate 211 to clamp or loosen the external wire inserted from the wire insertion hole 111. The button 300 is slidably assembled in the button assembly hole 112. Under the drive of an external force, the end of the button 300 located inside the housing 100 can press the first elastic member 220, so that the other end of the first elastic member 220 moves away from the clamping plate 211. The second elastic member 400 is arranged in the button assembly hole 112, and the second elastic member 400 is used to keep the button 300 separated from the first elastic member 220 without the drive of an external force.

[0065] The working principle of this quick wiring device is as follows:

[0066] When an external wire needs to be installed, one end of the external wire is inserted from the wire insertion hole 111. As the external wire is inserted, the external wire will contact and press the other end of the first elastic member 220, causing the other end of the first elastic member 220 to elastically deform and move away from the clamping plate 211. After the other end of the first elastic member 220 moves away from the clamping plate 211, the external wire will enter between the clamping plate 211 and the other end of the first elastic member 220. At this time, the insertion of the external wire is stopped. The other end of the first elastic member 220 will approach the clamping plate 211 under the action of the elastic restoring force and clamp the external wire between the other end of the first elastic member 220 and the clamping plate 211, completing the installation of the external wire.

[0067] If there is no external force pressing the button 300, the second elastic member 400 can always keep the end of the button 300 located inside the housing 100 separated from the first elastic member 220, thereby ensuring that the other end of the first elastic member 220 can reliably clamp the external wire with the clamping plate 211, improving the reliability of the installation of the external wire.

[0068] When it is necessary to disassemble the external wire, press the button 300 into the housing 100. The button 300 will slide in the button assembly hole 112 in the direction close to the first elastic member 220. As the button 300 slides further, the end of the button 300 placed inside the housing 100 will contact and press the other end of the first elastic member 220, causing the other end of the first elastic member 220 to elastically deform away from the clamping plate 211. When the other end of the first elastic member 220 moves away from the clamping plate 211, the external wire will be released. At this time, the external wire can be directly pulled out to complete the disassembly of the external wire.

[0069] During the process of disassembling the external wire, the second elastic member 400 is compressed to store elastic potential energy. After the external wire is pulled out from the wire insertion hole 111, if the pressing external force applied to the button 300 is removed, the button 300 can return to the initial position separated from the first elastic member 220 under the elastic restoring force of the second elastic member 400.

[0070] The quick wiring device provided in this embodiment can realize the quick plugging and unplugging of the wire without the aid of auxiliary tools, reducing the difficulty of connecting and disconnecting the wire and improving the efficiency of connecting and disconnecting the wire. By setting the second elastic member 400, on the one hand, it can keep the button 300 separated from the first elastic member 220 without external force, so that when the external wire does not need to be disassembled, the first elastic member 220 and the clamping plate 211 can reliably clamp and fix the external wire; on the other hand, after the external wire is disassembled, the second elastic member 400 can make the button 300 quickly reset under the action of the elastic restoring force, which is convenient to control.

[0071] Optionally, continue to refer to Figure 2 , in this embodiment, the housing 100 includes a base 120 and an upper cover 110 covering the base 120. The terminal installation space is arranged on the base 120, and the wire insertion hole 111 and the button assembly hole 112 are arranged on the upper cover 110. The structure of the housing 100 is simple, which is convenient for the installation of the quick plug terminal 200.

[0072] Furthermore, continue to refer to Figures 2 - 5, the button 300 includes a push rod 310 slidably connected to the button assembly hole 112, a pressing portion 320 provided at one end of the push rod 310 away from the first elastic member 220, and a first limiting portion 330 provided at one end of the push rod 310 close to the first elastic member 220. A limiting flange 113 protrudes from the inner peripheral wall of the button assembly hole 112. The second elastic member 400 is sleeved on the push rod 310. One end of the second elastic member 400 abuts against the first surface 1131 of the limiting flange 113, and the other end abuts against the pressing portion 320. The first limiting portion 330 can abut against the second surface 1132 of the limiting flange 113. The second surface 1132 and the first surface 1131 are oppositely arranged along the sliding direction of the push rod 310. With such an arrangement, when the second elastic member 400 elongates under the action of the elastic restoring force, the first limiting portion 330 abuts against the second surface 1132 of the limiting flange 113. In this state, the portion of the button 300 placed inside the housing 100 is separated from the first elastic member 220. That is, the limiting flange 113 and the pressing portion 320 cooperate to fix the second elastic member 400, and cooperate with the first limiting portion 330 to limit the button 300 from being disengaged from the button assembly hole 112. The structure is simple, and the control of the button 300 is also relatively convenient.

[0073] It can be understood that the second elastic member 400 is optional but not limited to a spring.

[0074] Further, continue to refer to Figure 4 , in order to enable the button 300 to be inserted into the button assembly hole 112, an avoidance notch 114 is provided on the limiting flange 113. When installing the button 300, make the first limiting portion 330 opposite to the avoidance notch 114, and then press the pressing portion 320 of the button 300 until the first limiting portion 330 passes through the avoidance notch 114, and then rotate the button 300 to make the first limiting portion 330 abut against the second surface 1132 of the limiting flange 113.

[0075] Further, continue to refer to Figure 3 and Figure 4 , the first limiting portion 330 includes one or more first limiting ribs 331 provided on the push rod 310, and each first limiting rib 331 corresponds to an avoidance notch 114. Providing a plurality of first limiting ribs 331 can increase the contact area between the first limiting portion 330 and the second surface 1132 of the limiting flange 113, and improve the limiting effect of the limiting flange 113 on the button 300.

[0076] Continue to refer to Figure 3 and Figure 4 , in this embodiment, two first limiting ribs 331 are provided, and the two first limiting ribs 331 are arranged at an interval of 90° along the circumferential direction of the push rod 310. In other embodiments, the number and arrangement manner of the first limiting ribs 331 can also be other, and can be set according to actual needs. The present application does not make specific limitations.

[0077] Further, continue to refer to Figure 5 , two first anti-rotation ribs 115 extending along the sliding direction of the push rod 310 are provided on the second surface 1132, and the two first anti-rotation ribs 115 enclose a first anti-rotation chute 116. The first limiting portion 330 is slidably disposed in the first anti-rotation chute 116. During the process of pressing the button 300, the first limiting portion 330 can slide in the first anti-rotation chute 116 to prevent the button 300 from rotating about its own axis.

[0078] In this embodiment, one of the first limiting ribs 331 is slidably disposed in the first anti-rotation chute 116.

[0079] Further, continue to refer to Figure 3 , Figure 4 and Figure 6 , on the housing 100, two second anti-rotation ribs 117 extending along the sliding direction of the push rod 310 are provided at the outer edge of the button assembly hole 112. The two second anti-rotation ribs 117 enclose a second anti-rotation chute 118. An anti-rotation portion 321 is provided on the pressing portion 320, and the anti-rotation portion 321 is slidably disposed in the second anti-rotation chute 118. During the process of pressing the button 300, the anti-rotation portion 321 can slide in the second anti-rotation chute 118 to prevent the button 300 from rotating about its own axis.

[0080] In this embodiment, the installation method of the button 300 is as follows:

[0081] Align the two first limiting ribs 331 on the button 300 with the two avoiding notches 114 respectively, and then insert the button 300 into the button assembly hole 112. During the insertion process of the button 300, when the bottom height of the anti-rotation portion 321 is the same as the top height of the second anti-rotation rib 117, rotate the button 300 until the anti-rotation portion 321 is opposite to the second anti-rotation chute 118, and then release the button 300. One of the first limiting ribs 331 will move upward under the elastic restoring force of the second elastic member 400 and enter the first anti-rotation chute 116.

[0082] In this embodiment, when pressing the button 300, before the anti-rotation portion 321 enters the second anti-rotation chute 118, the anti-rotation of the button 300 depends on the sliding connection between the first limiting rib 331 and the first anti-rotation chute 116. After the anti-rotation portion 321 enters the second anti-rotation chute 118, the anti-rotation of the button 300 depends on the sliding connection between the anti-rotation portion 321 and the second anti-rotation chute 118. At this time, the first limiting rib 331 disengages from the first anti-rotation chute 116. Through the cooperation of the first anti-rotation chute 116 and the second anti-rotation chute 118, both the first anti-rotation rib 115 and the second anti-rotation rib 117 do not need to be set too long, reducing the occupation of the internal and external spaces of the housing 100.

[0083] Optionally, the button 300 is of an integral structure, which is convenient for processing and has relatively high structural stability.

[0084] Optionally, continue to refer to Figure 2 and Figure 3 , a slope 311 is provided at the end of the push rod 310 close to the first elastic member 220, and the other end of the first elastic member 220 is inclined. The slope 311 is used to cooperate with the other end of the first elastic member 220. With such a setting, the contact area between the push rod 310 and the other end of the first elastic member 220 can be increased, avoiding the excessive concentration of force on the first elastic member 220 and being beneficial to protecting the first elastic member 220.

[0085] Furthermore, continue to refer to Figure 2 and Figure 3 , a second limiting portion 340 is provided on the push rod 310, and the second limiting portion 340 can abut against the first surface 1131. By providing the second limiting portion 340, the length of the push rod 310 entering the housing 100 can be limited, avoiding excessive deformation of the first elastic member 220 caused by the button 300 and resulting in fatigue failure of the first elastic member 220, and prolonging the service life of the first elastic member 220.

[0086] Optionally, continue to refer to Figure 2 and Figure 3 , the second limiting portion 340 includes one or more second limiting ribs 341.
