[0035] Reference below Figure 1-Figure 4 The socket grounding terminal structure according to the embodiment of the utility model is described.

[0036] like Figure 1-Figure 4 As shown, the socket grounding terminal structure includes a grounding terminal seat 100, a terminal fixing seat 200 and a grounding wire connecting seat 300. The grounding terminal seat 100 is used to be plugged with the grounding wire electrode of the plug, the terminal fixing seat 200 is used to increase the connection strength between the grounding terminal seat 100 and the socket to prevent the grounding terminal seat 100 from loosening, and the grounding wire connecting seat 300 is used to connect the ground wire, and the ground wire is connected to the grounding terminal seat 100 through the terminal fixing seat 200.

[0037] Specifically, both sides of the ground terminal seat 100 are bent toward the middle to form a plug slot 110, which is used to plug with the plug grounding electrode. The structure of the plug slot 110 is adjusted according to the grounding electrode of different standards, and the plug slot 110 can adopt the structure of the corresponding standards such as national standard, British standard or European standard according to the application environment.

[0038] The middle part of the terminal fixing seat 200 is bent to both sides, and a mounting groove 210 is formed in the middle part. The grounding terminal seat 100 is fixedly connected to the mounting groove 210 through a rivet 410, and both ends of the terminal fixing seat 200 are connected to the socket. The terminal fixing seat 200 is fixedly connected to the socket, and the grounding terminal seat 100 is riveted to the mounting groove 210 of the terminal fixing seat 200 through a rivet 410, so that the grounding terminal seat 100 is fixed to the mounting groove 210, and the terminal fixing seat 200 is installed on the socket, so that the grounding terminal seat 100 is fixedly connected to the socket.

[0039] Among them, a ground connection seat 300 is provided at one end of the terminal fixing seat 200, and the ground connection seat 300 is detachably connected to the ground wire, and the ground terminal seat 100, the terminal fixing seat 200 and the ground connection seat 300 are connected in sequence to form a grounding path. That is, the ground connection seat 300 is fixedly connected to the terminal fixing seat 200, and the terminal fixing seat 200 is used as a connecting bridge, so that the ground connection seat 300 and the ground terminal seat 100 are both connected to the terminal fixing seat 200, and the terminal fixing seat 200 is made of metal material, so that the ground terminal seat 100 and the ground connection seat 300 are connected, so that the ground wire and the plug ground wire electrode are connected.

[0040] The existing grounding terminal and ground wire are usually directly connected. When the grounding terminal is loose, the connection between the ground wire and the grounding terminal is prone to poor contact. The utility model adds a terminal fixing seat 200 as a connection medium, so that the ground wire connection seat 300 and the grounding terminal seat 100 are respectively connected to the terminal fixing seat 200, and the connection between the terminal fixing seat 200 and the socket is more stable, thereby ensuring the stability of the grounding terminal seat 100 and the stable contact between the ground wire and the grounding terminal seat 100.

[0041] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the width of the mounting groove 210 of the terminal fixing seat 200 is greater than the width of the two ends of the terminal fixing seat 200. Specifically, in order to ensure that the mounting groove 210 can be firmly connected to the grounding terminal seat 100, the bottom of the mounting groove 210 is widened, thereby increasing the contact area between the bottom of the mounting groove 210 and the grounding terminal seat 100 and improving the connection stability.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a rivet hole 420 is provided at the bottom of the installation slot 210 , and a rivet hole 420 is correspondingly provided at the bottom of the plug-in slot 110 . The rivet piece 410 passes through the two rivet holes 420 to fix the ground terminal seat 100 and the terminal fixing seat 200 .

[0043] Specifically, the rivet holes 420 of the mounting slot 210 and the rivet holes 420 of the plug slot 110 have the same diameter, and the rivet piece 410 passes through the two rivet holes 420 and is riveted to the terminal fixing seat 200, thereby pressing the plug slot 110 and the mounting slot 210 to make the two fit tightly.

[0044] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the groove width of the installation groove 210 is greater than the groove width of the plug-in groove 110. Specifically, the width of the grounding terminal seat 100 varies according to different standards, and the groove width of the installation groove 210 is greater than the groove width of the plug-in groove 110, so that the installation groove 210 of the terminal fixing seat 200 can adapt to grounding terminal seats 100 of various specifications.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the two ends of the terminal fixing seat 200 are provided with connection holes 220, and the terminal fixing seat 200 is threadedly connected to the socket through the connection holes 220. Specifically, the connection holes 220 at the two ends of the terminal fixing seat 200 are pressed against the socket mounting surface by screws, so that the two ends of the terminal fixing seat 200 are stably connected to the socket, and the two-side connection makes the force of the terminal fixing seat 200 more balanced, which can reduce the shaking of the grounding terminal seat 100 during the plugging and unplugging process of the grounding terminal seat 100 and the plug.

[0046] In a further embodiment, Figure 1 and Figure 2 As shown, both ends of the terminal fixing seat 200 are in annular shape.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a ground wire mounting hole 230 is provided at one end of the terminal fixing seat 200, and the bottom of the ground wire connecting seat 300 is welded to the ground wire mounting hole 230. Specifically, a ground wire mounting hole 230 is provided at any end of the terminal fixing seat 200, and the ground wire mounting hole 230 is welded to the ground wire connecting seat 300 so that the ground wire mounting seat and the terminal fixing seat 200 are connected.

[0048] In a further embodiment, Figure 2-Figure 4 As shown, the middle of the ground connection seat 300 is through-through, and the side wall is inclinedly provided with a threaded hole 310. A clamping piece 430 is threadedly connected with the threaded hole 310 and extends into the inside of the ground connection seat 300. The clamping piece 430 is used to clamp the ground wire in the ground connection seat 300. Specifically, the middle of the ground connection seat 300 is through-through to accommodate the ground wire. After the ground wire is inserted into the ground connection seat 300, the clamping piece 430 is tightened in the threaded hole 310 so that the end of the clamping piece 430 clamps the ground wire.

[0049] In a further embodiment, Figure 2-Figure 4 As shown, the threaded hole 310 is inclined toward the bottom of the ground connection seat 300, so as to enable the clamping member 430 to clamp the ground wire. When the clamping member 430 is screwed into the threaded hole 310, the clamping member 430 can drive the ground wire to move toward the bottom of the ground connection seat 300 to prevent the ground wire from being separated from the ground connection seat 300.

[0050] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the top inner circle of the ground connection base 300 is chamfered, which facilitates the insertion of the ground wire from the top of the ground connection base 300 and plays a guiding role.
